GUIDING PRINCIPLES FOR PHYSICIANS RECOMMENDING MOBILE HEALTH APPLICATIONS TO PATIENTS
This document is designed to provide basic information for physicians about how to assess a mobile health application for recommendation to a patient in the management of that patient's health, health care, and health care information.
These guiding principles build on the Canadian Medical Association's (CMA) Physician Guidelines for Online Communication with Patients.1
* Mobile health applications, distinct from regulated medical devices, may be defined as an application on a mobile device that is intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, treatment, or prevention of disease. The functions of these applications may include:
o The ability to store and track information about an individual or group's health or the social determinants thereof;
o Periodic educational information, reminders, or motivational guidance;
o GPS location information to direct or alert patients;
o Standardized checklists or questionnaires.2
* Mobile health applications can enhance health outcomes while mitigating health care costs because of their potential to improve a patient's access to information and care providers.3
* Mobile health applications are most commonly used on a smart phone and/or tablet. Some may also interface with medical devices.
* The use of mobile health applications reflects an emerging trend towards personalized medicine and patient involvement in the management of their health information. By 2016, 142 million health apps will have been downloaded.4 According to some industry estimates, by 2018, 50 percent of the more than 3.4 billion smartphone and tablet users worldwide will have downloaded at least one mobile health application.5
* While mobile health application downloads are increasing, there is little information about usage and adherence by patients. It is believed that many patients cease to use a mobile health application soon after downloading it.
* Distributers of mobile health applications do not currently assess content provided by mobile health applications for accuracy, comprehensiveness, reliability, timeliness, or conformity to clinical practice guidelines.6 However, mobile applications may be subjected to certain standards to ensure critical technical requirements such as accessibility, reachability, adaptability, operational reliability, and universality.
* Increasingly there are independent websites providing reviews of medical apps and checklists for health care professionals. However, the quality criteria used by these sites, potential conflicts of interest, and the scope and number of mobile apps assessed are not always declared by these groups.
To date, randomized controlled trials are not usually employed to assess the effectiveness of mobile health applications. Some believe that the rigorousness of this type of assessment may impede the timeliness of a mobile health application's availability.7
* Some examples of the uses of mobile health applications include tracking fitness activities to supplement a healthy lifestyle; supported self-management of health and health information; post-procedure follow up; viewing of test results; and the virtualization of interaction between patients and providers, such as remote patient monitoring for chronic disease management. Some mobile health applications may be linked to a patient profile or patient portal associated with a professional or recognized association or medical society or health care organization.
* Some mobile health applications may be an extension of an electronic medical records (EMR) platform.
* The objective of recommending a mobile health application to a patient must be to enhance the safety and/or effectiveness of patient care or otherwise for the purpose of health promotion.
* A mobile health application is one approach in health service delivery. Mobile health applications should complement, rather than replace, the relationship between a physician and patient.
* No one mobile health application is appropriate for every patient. Physicians may wish to understand a patient's abilities, comfort level, access to technology, and the context of the application of care before recommending a mobile health application.
* Should a physician recommend a mobile health application to a patient, it is the responsibility of the physician to do so in a way that adheres to legislation and regulation (if existing) and/or professional obligations.
* If the mobile health application will be used to monitor the patient's condition in an ongoing manner, the physician may wish to discuss with the patient what they should watch for and the steps they should take in response to information provided.
* Physicians are encouraged to share information about applications they have found effective with colleagues.
* Physicians who require additional information about the competencies associated with eHealth and the use of health information technologies may wish to consult The Royal College of Physicians and Surgeons of Canada's (RCPSC) framework of medical competencies, CanMEDS.8
* Physicians may wish to enter into and document a consent discussion with their patient, which can include the electronic management of health information or information printed out from electronic management platforms like mobile health applications. This agreement may include a one-time conveyance of information and recommendations to cover the elements common to many mobile health applications, such as the general risk to privacy associated with storing health information on a mobile device.
Characteristics of a safe and effective mobile health application
A mobile health application does not need to have all of the following characteristics to be safe and effective. However, the more of the following characteristics a mobile health application has, the likelier it will be appropriate for recommendation to a patient:
1. Endorsement by a professional or recognized association or medical society or health care organization
As recommended by the Canadian Medical Protective Association (CMPA), it is best to select mobile health applications that have been created or endorsed by a professional or recognized association or medical society.9 Some health care organizations, such as hospitals, may also develop or endorse applications for use in their clinical environments. There may also be mobile health applications associated with an EMR platform used by an organization or practice. Finally, some mobile health applications may have been subject to a peer review process distinct from endorsement by an association or organization.
There are a number of usability factors than can complicate the use of mobile applications, including interface and design deficiencies, technological restrictions, and device and infrastructure malfunction.
Many developers will release periodic updates and software patches to enhance the stability and usability of their applications. Therefore, it would be prudent for the physician recommending the mobile health application to also recommend to the patient that they determine if the application has been updated within the last year.
Physicians considering recommending a mobile health application to a patient may wish to ask about the patient's level of comfort with mobile health technologies, their degree of computer literacy, whether or not the patient owns a mobile device capable of running the application, and whether or not the patient is able to bear potential one-time or ongoing costs associated with use of the application.
Physicians may consider testing the application themselves beforehand to understand whether its functionality and interface make it easy to use.
3. Reliability of information
Physicians considering recommending a mobile health application may wish to understand how the patient intends to use the information, and/or review the information with the patient to understand whether it is current and appropriate.
Information presented by the mobile health application should be appropriately referenced and time-stamped with the last update by the application developer.
4. Privacy and security
In 2014, the Officer of the Information and Privacy Commissioner of Alberta assessed approximately 1200 mobile applications and found nearly one-third of them required access to personal information beyond what should be required relative to their functionality and purpose, and that basic privacy information was not always made available.10
Physicians entering into and documenting a consent discussion with their patients may wish to include the electronic management of health information in the scope of these discussions, and make a notation of the discussion in the patient's health record.
Some mobile health applications may feature additional levels of authentication for use, such as an additional password or encryption protocols. If all other factors between applications are equal, physicians may wish to recommend that patients use mobile health applications adhering to this higher standard of security.
5. Avoids conflict-of-interest
Physicians may wish to recommend that patients learn more about the company or organization responsible for the development of the application and their mandate. There is a risk of secondary gains by mobile health application developers and providers where information about patients and/or usage is gathered and sold to third parties.
A standardized conflict of interest statement may be made available through the mobile health application or on the developer's website. If so, physicians may wish to refer the patient to this resource.
Physicians who develop mobile applications for commercial gain or have a stake in those who develop applications for commercial gain may risk a complaint being made to the College on the basis that the physician engaged in unprofessional conduct if they recommend mobile health applications to their patients in the course of patient care.
6. Does not contribute to fragmentation of health information
Some mobile health applications may link directly to an EMR, patient portal, or government data repository. These data resources may be standardized, linked, and cross-referenced.
However, health information entered into an application may also be stored on a mobile device and/or the patient's home computer, or developers of mobile health applications may store information collected by their application separately. While there may be short-term benefits to using a particular mobile health application, the range of applications and developers may contribute to the overall fragmentation of health information.
If all other factors between applications are considered equal, physicians may wish to recommend mobile health applications which contribute to robust existing data repositories, especially an existing EMR.
7. Demonstrates its impact on patient health outcomes
While not all mobile health applications will have an appropriate scale of use and not all developers will have the capacity to collect and analyze data, physicians may wish to recommend mobile health applications that have undergone validation testing to demonstrate impact of use on patient health outcomes. If mobile health applications are claiming a direct therapeutic impact on patient populations, physicians may wish to recommend that their patients seek out or request resources to validate this claim.

The Canadian Medical Association (CMA) supports the promotion of healthy lifestyles in order to improve individual health and well-being and the overall health status of the population. Healthy lifestyles refer to patterns of individual practices and personal behavioural choices that are associated with optimal health. Two of the most important behaviours to create or maintain optimum health are healthy eating and physical activity.
For many Canadians, their diet and physical activity levels can have a negative rather than positive impact on their overall health. There is a particular concern for children and youth who are growing up in increasingly obesogenic environments that reinforce practices that work against a healthy lifestyle.1 Childhood obesity research tells us that overweight and obese children are more likely to stay the same into adulthood.2 To reverse this trend, determined action is required for children and youth to learn and acquire healthy behaviours that they will maintain throughout their life. Healthy lifestyles are central to successful aging and improving the likelihood of recovery after poor health.3
This policy paper discusses the importance of physical activity and healthy eating, and the role that individuals and families, schools, workplaces, communities, the food industry and all levels of governments can play in promoting healthy lifestyles. We know that collaborative action is required to make it easier for Canadians to incorporate healthy eating and physical activity into their daily lives - to make the healthy choice the easy choice.
What are the health impacts of unhealthy diets and physical inactivity
Diet is the leading risk factor for death, disability and life-years lost; being estimated to cause over 65,000 deaths and 864,000 life years lost in Canada in 2010.4
Unhealthy diet has been consistently linked with cardiovascular diseases (heart disease, stroke, hypertension, diabetes, dyslipidemia) and some cancers,5 which constitutes the majority of the disease burden in Canada. An estimated 80% of hypertension, which affects over 7 million Canadians, is directly or indirectly attributed to unhealthy diet.6
An estimated 60% of Canadian adults and close to one-third of children are overweight or obese, largely caused by unhealthy diets.7 Overweight and obesity (and the lifestyle choices associated with them) are contributors to more than 18 chronic conditions.8 This includes diabetes, cardiovascular disease, hypertension and liver disease, as well as breast, colon and prostate cancer.
Obesity is a public health issue not unique to Canada as the rates are increasing worldwide. Obesity is generally attributed to the fact that, as a society, we are increasing our calorie intake while at the same time burning less energy in physical activity. While it is difficult to determine how many deaths are directly attributable to obesity, we know that obesity often co-exists with other risk factors such as the lack of physical activity.
Exercise is one of the top modifiable risk factor for chronic disease.9 Regular physical activity is associated with a reduced risk of cardiovascular disease, some types of cancer, diabetes, obesity, hypertension, bone and joint diseases, and depression.10 The risk for many of these conditions is reduced by 20 - 40% in adults with the highest levels of physical activity compared to those with the lowest levels of physical activity. Recent research has shown that a sedentary lifestyle is associated with higher risk for chronic conditions such as obesity, diabetes and cancer independent of physical activity levels.11
According to the most recent Canadian Health Measures Study physical activity levels for children and youth are low with 6 out of 10 waking hours devoted to sedentary pursuits. Obesity is rising and physical fitness is declining.12
Canadians who do not achieve adequate levels of physical activity or eat unhealthy foods are vulnerable to preventable chronic diseases, premature death, and contribute to high health care costs. For instance, in 1999, $2.1 billion or 2.5% of the total direct health care costs were attributable to physical inactivity.13
To understand why the rates of obesity and overweight are rising, it may be helpful to look at what we already know about healthy eating and physical activity.
What we know about healthy eating
While modern science has allowed us to expand our knowledge of the impact of nutrients and food on human health we continue to be beset with illness and disease caused by the foods we consume. Having the right amount and type of food recommended in Canada's Food Guide is a first step towards healthy eating. But Canadians self-reported dietary intakes do not meet national dietary recommendations despite high reliance on public education concerning healthy eating and healthy diets. Children and adults are under-consuming the recommended servings of vegetables and fruits, an established proxy for healthy eating habits, and exceeding daily recommended intakes of sodium.14,15
As the links between nutrition and disease, and the impact on the health of our society are revealed it is more important than ever to understand what influences healthy eating behaviours. Food choices are structured by a variety of individual determinants of behaviour, ranging from one's physiological state, food preferences, nutritional knowledge, perceptions of healthy eating and psychological factors.
Many processed foods have become popular due to their accessibility and 'convenience factor', but these features have changed the way food and in particular these products are consumed compared to unprocessed foods: increased 'grazing', eating alone or eating while carrying out other activities such as work or driving. In addition, many calories consumed come in liquid form.16
Growth in the production and consumption of ultra-processed foods has increased drastically in the last decades in both higher and lower-income countries.17 A number of studies have shown that because less healthy foods are cheaper than healthier food, individuals from lower socioeconomic classes tend to be more dependent on unhealthy foods for nourishment.18
Other determinants for healthy eating include a wide range of contextual factors, such as the interpersonal environment created by family and peers, the physical environment, which determines food availability and accessibility, the economic environment, in which food is a commodity to be marketed for profit, and the social environment. Within the social environment, social status (income, education and gender) and cultural milieu are determinants of healthy eating that may be working "invisibly" to structure food choice.19
What we know about physical activity
Canada's Physical Activity Guidelines recommend that children and youth aged 5 to 17 get at least 60 minutes of moderate-to-vigorous physical activity (MVPA) per day; and adults get 150 minutes of physical activity per week.20 In fact, about 94% of Canadian children and youth do not meet minimum physical activity guidelines.21 Furthermore, about 85% of Canadian adults do not meet the minimum guidelines. Physical activity includes but is not limited to sports and recreation. Using active transportation to get to work as well as being active at work is an alternative form of MVPA and can also lead to improved health.
For most Canadians, the average day is spent on passive activities such as TV viewing, computer and game-console use, workplace sitting, and time spent in automobiles. Moreover, the sprawling suburban communities, in which many live, do not encourage physical activity.
Emerging research suggests that prolonged sitting time is associated with an increased health risk.22 These findings mean that one can meet the minimum physical activity guidelines and still not engage in a healthy lifestyle. Spending a few hours a week at the gym or otherwise engaged in moderate or vigorous activity doesn't seem to significantly offset the risk. Hence too much sitting is a risk distinct from too little exercise.
While further research is required to identify which methods of exercise promotions work best for individuals,23 it is clear that supportive environments and infrastructures are essential for Canadians to make physical activity part of their daily lives. CMA's policies about the Built Environment and Active Transportation support the role of the environment on our physical activity patterns.
How we can promote physical activity and healthy eating
A sedentary lifestyle is a cue for physician advice.24 Physical activity is a vital sign that may require as much attention as other traditional vital signs25 - weight, blood pressure, or smoking history. Physicians are eager to initiate these conversations, especially with patients living with chronic diseases. A message must be repeated many times in order to effect a change in lifestyle. Physicians can reiterate the medical importance of physical activity and healthy eating by reinforcing this message during each office visit, and writing the recommendation on a prescription pad.26 For instance, in British Columbia, physicians are prescribing exercise on specially-designed pads, distributing free pedometers, and hosting free walking events for their patients and the public. In the Edmonton area, Primary Care Networks are prescribing free access passes or a free month of access at local municipal recreation facilities. And in Nova Scotia, physicians have been running a free provincial running program for over 10 years that benefits thousands of kids in elementary school.
Nonetheless these clinical interventions alone cannot shape healthier food consumption patterns and lifestyle choices. An obvious starting point to develop a comprehensive policy is to understand the interplay between individual and environmental determinants that influence our behaviours. In this regard, CMA has developed policies on Active Transportation and the Built Environment and Health which recognize the role of neighborhood design and alternative modes for transportation for an active lifestyle. This approach is also at the heart of the Integrated Pan-Canadian Healthy Living Strategy (PCHLS)27, approved in 2005 by all levels of government. CMA commends the efforts put in the PCHLS to prioritize healthy eating and physical activity.
What we recommend
CMA looks forward to working with others in making options for physical activity and healthy eating more available and accessible to all Canadians. The following recommendations highlight the potential contributions of the following sectors: health professionals, all levels of government, communities, workplaces, schools, the food industry and individuals and families.
CMA encourages physicians to promote healthy eating and physical activity inside and outside their office.
Physicians are lifestyle change agents and remain the preferred source of information about health for many people. Physicians, who are committed to physical activity, are role models whose advice on healthy living is more likely to be adopted.28 CMA encourages physicians to address any work-imposed limitations - such as the lack of time, motivation, or tiredness - that could also influence their own exercise and eating habits.
In clinical practice, physicians can help patients start or maintain a healthy lifestyle by:
* assessing nutrition and physical activity as part of routine assessments;
* determining the factors that influence individual patient's nutrition and physical activity levels;
* assessing patient's readiness to change and tailoring interventions and support to their current situation;
* providing an exercise prescription to encourage physical activity to maintain or improve health status, and
* working in inter-professional teams to provide patient education with other health care providers such as dieticians.
Medical students and residents, while reporting a high level of importance for exercise prescription concede a low level of expertise in this area upon graduation.29,30,31 As knowledge develops, physicians and other health professionals should be kept updated and encouraged to incorporate the most effective interventions into their practices. The CMA encourages the development of continuing medical education courses on issues related to physical activity and healthy eating.
Within the healthy living approach, there are multiple opportunities to extend the role of physicians into the community as observed in Nova Scotia, British Columbia and Edmonton area. Physicians can establish strong community norms for a healthy lifestyle by:
* establishing and reinforcing healthy food policies in hospital cafeterias or at health-related meetings and conferences
* using, facilitating and advocating for the use of active transportation in their communities
* working within the community to ensure that recreation centres and other facilities are available and patients can be referred to the services most appropriate to their needs
Federal, Provincial, and Territorial Governments
CMA calls on federal, provincial, territorial and municipal governments to commit to a long-term, well-funded Canada-wide strategy for healthy living beyond 2015.
In 2005, Canada's federal, provincial, and territorial governments endorsed a 10-year Healthy Living Strategy Framework, whose initial priorities included the promotion of healthy eating and physical activity. The national strategy addressed information and support for Canadians to help them make healthy choices; support for physicians and other health professionals in counselling patients on healthy weight and in treating existing obesity; community infrastructures that make healthy living easier; and public policies that encourage healthy eating and physical activity. The federal and provincial / territorial governments have undertaken a number of activities in the intervening years to promote physical activity and healthy eating but much remains to be done.
CMA believes that all levels of governments have a continuous obligation to provide public guidance on healthy eating and to promulgate policies, standards, regulations and legislations that support the availability and accessibility of healthy and affordable food and beverage choices.
CMA calls on governments to improve access to nutritious food at affordable prices for all Canadians.
The price of milk, fresh produce and other healthy foods can vary greatly across Canada. In many remote areas, they are often more expensive than processed, nutrition-poor foods because of high transportation costs. Governments should implement effective programs to offset the impact of transportation costs on food prices in northern and remote communities. Even in urban areas, nutritious food may be unaffordable for people on low incomes. School meal programs, social assistance rates that take into account the cost of purchasing healthy food, access to urban farmers' markets can help to ensure that all Canadians have access to healthy foods at a reasonable price.
CMA calls on governments to ban marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
The typical Canadian child may be exposed to as many as 40,000 advertisements for food a year.32 This does not include point-of-sale promotions, such as displays of candy bars at convenience-store counters. CMA's policy on marketing of unhealthy foods and beverages to children and youth calls for a ban on marketing of foods and beverages high in salt, sugars and trans fats to those 13 years of age and younger.
CMA calls on governments to set rigorous standards for front of package food labeling and for the advertising of health claims for food.
Brand-specific advertising is a less than optimal way to provide health information to consumers, who should be encouraged to seek out objective information sources for answers to their questions about physical activity and healthy eating. To improve the quality of information received through commercial channels, the CMA recommends that health claims made for foods be strictly regulated to ensure that they are based on the best available scientific evidence and that they are accurately communicated to consumers. Food advertisements should be pre-cleared before airing in the media, and the provisions against deceptive advertising in the Food and Drug Act should be strengthened.
CMA recommends that governments at all levels invest in evidence-based research on healthy eating and physical activity and share the results of this research with all Canadians.
CMA encourages all levels of governments to continue to fund and support research for healthy lifestyles. There is a clear need to invest in research to strengthen the evidence base about physical activity and healthy eating, particularly on:
best measures for assessing overweight and obesity;
the effectiveness of weight management and treatment programs; and
the effect of policy interventions on healthy eating and physical activity on rates of obesity and obesity-related disease.
CMA encourages governments to continue to work with the food industry to improve the food environment in Canada.
The partnership and collaboration of food manufacturers is needed to help Canadians make healthier food choices. The food industry can work with governments to:
reduce the salt, sugar, saturated fat, trans fat and calorie content of processed foods and pre-prepared meals;
provide information about the calorie and nutrition content on restaurant menus;
restrict advertising and in-store promotion of high-sugar, high-salt, high-fat foods, particularly those aimed at children;
provide user-friendly consumer information about their products, including and accurate health and advertising claims;
improve the nutrition fact table to make it more user friendly and increase the amount of information for example, by identifying the amount of free sugars.
CMA calls on municipal governments to create environments that encourage healthy and active living and on federal, provincial and territorial governments to support them in this endeavour.
Communities have an important role to play to promote healthy behaviours for children, youth, and adults. They shape how many Canadians decide to live, work and play in their daily life. Through mixed-use land planning and building design, communities can create walking-friendly environments, and reduce the time people spend in cars. To achieve this, communities should consider:
developing and maintaining a community-wide network of walking and cycling paths;
zoning communities in such a way that amenities are within walking distance of homes; and
revising building codes to make stairs accessible, pleasant and safe, so that people have an alternative to taking the elevator.
Canadians are considerably more physically active in the summer than in the winter and this could have an impact on obesity trends.33 Communities could improve pathways to healthy lifestyles year-round by improving access to indoor sport and recreation facilities, especially during winter. Where possible, communities should consider partnering with schools to share the use of gymnasiums, playgrounds, fields, courts, and tracks with the public after school hours and on weekends. In doing so, communities are ensuring the best use of time and resources, but also sharing liability for the development, operation, and maintenance of the facilities.
Community food security can happen if local residents have equal access to safe, affordable and nutritious food. Communities have a role to play in advocating for healthier food options in schools and workplaces, encouraging community kitchens to teach cooking skills, and supporting local agriculture and farmers markets. This, in turn, would encourage individuals to eat more healthy foods.
CMA encourages employers to actively promote the health of their employees by providing opportunities for physical activity, and healthy food choices in cafeterias.
Prolonged, unbroken time spent sitting in front of a screen is very common in the workplace. In addition, four out of five commuters sit daily in their private vehicles to go to work.34 As Canadians spend most of their adult life at work, it is important to reduce workplace sitting. CMA encourages employers, especially in sedentary occupational groups, to increase opportunities for physical activity. For example, employers can promote healthy behaviours by:
Building on-site fitness facilities or entering into agreements with off-site fitness centres to provide programs for their employees
Providing showers, bike racks and other amenities for employees for those who want to commute to work on foot or by bike.
Healthier food options in cafeteria and vending machines can promote and encourage healthy eating by employees.
Schools, where children spend most of their time outside of home, present an excellent opportunity to instil healthy behaviours at an early age. They could, for example, provide comprehensive nutrition education, serve nutritious food in their cafeterias and promote physical activity by providing formal instruction and informal recreation time. Schools can provide the most effective and efficient way to reach not only the children themselves, but their parents, teachers, and other community members.35
CMA encourages school boards to provide at least 60 minutes of active daily physical education for all primary and secondary grades.
Only 26% of Canadian schools reported that they had implemented daily physical education classes for their students.36 There is some evidence that school-based physical activity can increase physical activity levels and reduce time spent watching television at home. 37 For instance, schools can promote physical activity through unstructured out-of-home play, structured sports, or active transportation (e.g. walking to school). Children who are physically active and spend less time watching television after school are less likely to become overweight before age 12.38
CMA recommends that schools provide access to attractive, affordable, healthy food choices, provide nutrition education, and initiate programs aimed at encouraging healthy food consumption and skills to prepare meals from scratch.
CMA calls for restrictions on the sale of high-calorie, high fats, sugars or salts foods/drinks in recreational facilities frequented by young people.
Fast food restaurants and convenience stores can be an important influence on children's eating habits and food choices.39 Children attending schools within a short distance of fast food restaurants eat fewer fruits and vegetable servings, and drink more soft drinks than others who did not have similar establishments within proximity.40 To encourage effective school-based nutrition interventions, it is therefore important to educate students about the nutrition value of foods, healthy food choices, and provide healthy canteens or cafeterias.
Individuals and families
CMA recommends that all Canadians work toward achieving and maintaining health by:
educating themselves about their dietary needs and about the caloric and nutrition content of foods; and
engaging in physical activity, with the goal of at least 60 minutes of moderate activity per day for children and youth, and 150 minutes per week for adults.
Ultimately, healthy eating and physical activity require that individuals take action to make healthy choices in their lives. To inform these choices, Canadians should be supported with appropriate resource materials with consistent information about healthy eating and physical activity. For instance, many young children do not choose what they consume; their parents buy and prepare the food for them. Research suggests that mothers and children appear to have divergent attitudes towards food and mealtimes.41 In this regard, it is important for parents to be well-informed and able to explain the tangible benefits of foods and their nutritional components to their children before they reach adulthood.
What we conclude
Healthy behaviours are easier to maintain through life if acquired in childhood and encouraged by the family. Therefore Canadian families should be supported in efforts to ensure that both children and adults eat nutritiously and exercise daily. We believe there is a role for everyone in promoting healthy behaviours - including health professionals, individuals, families, schools, workplaces, communities, the food industry and all levels of governments.
Popular approaches seek to provide individuals with information and options about healthy lifestyles choices. However, individual choice is not sufficient to ensure healthy behaviours.
Many barriers to the adoption of healthy behaviours and lifestyle choices can be met through a targeted population health approach, and evidence-based policy and regulatory controls. A comprehensive change in culture and mindset, political endorsement and multifaceted strategies are needed to promote and facilitate change to improve the dietary practices and physical activity levels of Canadians.

The Role of Physicians in Recognizing and Supporting
Treatment of Gambling Addiction
(Update November 2005)
Gambling is a common activity in our society. For a small percentage, this behaviour can become pathological, affecting the well-being of gamblers as well as their families and workplaces. This disorder has been described in the "Diagnostic and Statistical Manual of Mental Disorders" Fourth Edition, (DSM IV) and is recognized as an illness by physicians.
Physicians have a role in identifying pathological gambling behaviour and being aware of the resources that exist to treat and support addicted individuals and their families. To assist them in performing this role, the CMA makes the following recommendations:
* The CMA supports the development of core curricula in gambling disorders to be offered at undergraduate and post-graduate levels and through CME programs. These could include inter-professional or interdisciplinary curricula developed in partnership with other health professionals.
* The CMA supports the development and dissemination of resources to help practising physicians screen patients to identify those with gambling addiction and to provide appropriate treatment.
* Governments should ensure the timely availability of quality treatment services appropriate to the age, culture and background of client groups.
* The CMA encourages research into gambling addiction, which could include:
identifying the biological basis for gambling;
identifying best-practice interventions to reduce the prevalence of problem gambling;
measuring the social and economic impacts of gambling on individuals and communities; and
dispelling the myths surrounding gambling addiction.
* Governments and others should work together to implement educational and policy strategies to reduce the prevalence of problem gambling. These could include:
elementary school programs to help prevent pathological gambling disorders;
limiting the number of gambling establishments, particularly video lottery terminals (VLTs) and casinos;
placing age limits on accessibility to VLTs so that children and adolescents are restricted from their use; and
promoting lower risk gambling approaches for primary prevention and harm reduction such as gambling only with a predetermined loss limit and not gambling alone.
