2  1. Are current and future cohorts/ generations becoming healthier?  2. What can we do to improve?

3  2001 – 13.6% of population  %  2011 – 15.3% Projected  2021 – 20.4%  2031 – 25.2%

4

5  Dychtwald (1997) Baby boomers are “train wrecks about to happen” (pandemic of chronic disease, mass dementia, inadequate pensions & pressures on deteriorating health care system)

6  Over $120 billion in 2007  Over $180 billion in total costs to the economy  Not surprising that someone has to be blamed – often older adults  Prevention may be the largest untapped area for cost savings*

7 What Constitutes Good Health?

8 Statistics Canada, 2006 Life Expectancy at Birth, Canada,

9  Onset of disease and disability compressed into a shorter time frame (Fries, 1983)  – 2% per year decline in functional disability, 1% decline in mortality  Evidence from

10  Moderate support, but mostly for less severe disability, 75+; but also declining recovery (Wolf et al., 2007)  Less support when examining other measures of health (chronic illness, perceived health)

11  1978/79 to 1998/99 decreases in arthritis, hypertension, heart disease, bronchitis/emphysema for person (Statistics Canada, 1999)  Increases in diabetes, asthma & migraines  For 65+, no declines (positive trends); but diabetes, dementias, & asthma up  Cancers show unique and complex trends

12  Rising life expectancy and disability compression concurrent with rising rates of many chronic illnesses  Due to changes in utilization and health care? Improved services and technology to facilitate independence? Or healthy lifestyles?

13 Some state that older adults today and the future older adults of tomorrow (the boomers) are healthier than previous generations because they are wealthier, exercise, eat better, and knowledgeable about healthy lifestyles

20  Smoking increases mortality by 50% and doubles incidence of cancer and cardiovascular disease (CACR, 1999)  Quitting can lower risks within one year

21  Physically inactive have a 90% higher risk of developing CVD; 60% osteoporosis; and 40% higher risk of stroke, hypertension, colon cancer, and diabetes (Katzmarzyk et al., 2000)  Benefits of physical activity can be realized immediately no matter what age

22  Obese individuals are more than twice as likely to have arthritis, heart disease, breast & colon cancer (Cairney and Wade, 1998)

23  Unique health and illness trajectories connected to the size and composition of cohorts, and to earlier life experiences, normative milieu and historical events  Upward bound age escalator

28  Paradox - exercise and obesity moving in opposite directions  Is the exercise measure flawed?

29 Statistics Canada, 2007 Leisure-time Physical Activity % Inactive, Canada, 1994/95 – 2002/03 AgeNPHS 1994/95CCHS %50.1 % %51.6 % %51.0 % %50.3 % %59.6 %

30  Among ages in 2000/01, there is a 25% relative risk reduction in obesity rate (>=30) among frequent exercisers compared to infrequent/sedentary  19% relative risk reduction in infrequent/sedentary activity among those who are not obese, compared to those who are not

31  Most studies linking TV and exercise or obesity are cross-sectional  Therefore problems of causality – which comes first?

32  Jeffery & French (1998)  TV watching associated with obesity at cross sectional level, but only among low- income women  At longitudinal level, no associations were supported

33  Canadian TV watching dropped from 23.3 hours/week in 1991 to 21.5 hours/week in 2000 (Statistics Canada, 2001)  For workers, average time spent watching TV dropped from 95 minutes in 1986 to 79 minutes in 2005 (Statistics Canada, 2007)

34  Computer use at work has doubled between 1989 and 2000 (33% to 57%) (GSS 2000)  80% of Canadians work at their computer every day  But, it is not enough to tip the scales, given exercise improvements

35  Consumption of fruits has increased 27% between the 1970s and 1997 (Alain, 1999)  Low fat milk up (e.g., 1% milk up from 12% in 1990 to 27% in 1997)  Consumption of red meat down

36  Over 25% of energy burned by adolescents and adults originates from the “Other Food Group” (Starkey at al., 2001)

37  Pop consumption in Canada doubled between 1975 and 1997, from 60 liters to 106 liters per person per year (Alain, 1999)

38  20% of all meals are consumed out of the home (Struempler, 2002)  Especially fast & inexpensive meals  McDonalds continues to lead the way

39  Average serving size has increased between 20% - 70% over past two decades  2-3 times the USDA recommended food size (Kendall, 2000)

40  Collected information on foods purchased in 24 hours before survey  Fast food sources predict obesity in men and women

41  Therefore it is both the quality and the quantity of food consumption that is the problem

42 Why Do We Have Poor Lifestyles?

43  Boomers report time issues more often, seniors repot energy  Perception that when we age, we need to slow down  Health is a major issue for older adults  Energy drops from some  Fear of falling  But, it is never too late – Plethora of Intervention Studies

44

45  13% of Canadians reported that they did not have time to prepare a healthy meal  74% eat in a hurry  39% eat in a vehicle at least once a week because of a busy work schedule (FPT Advisory Committee on Population Health, 1999)  40% of Canadian older adults report that they do not have the time or energy to exercise regularly

46

47  Over 50,000 diets in existence  Disagreement over what is good and what is bad  Concept of lifestyle change is not part of most diets

48  Presentation of fast food is a multimillion dollar industry (Schlosser, 2002)  Low fat everything rather than making substantive changes to lifestyle habits  Positive lifestyle messages must compete on an uneven playing field  Messaging active lifestyles is easier than you think – axioms of inertia

49

50  Okinawa, Japan Reason for living; social connectedness; physically active; low caloric intake – fish soup (highest obesity rate due to change in diet)  Sardinia More males; less stress; family and social connectedness; Mediterranean diet; mountain walking  Loma Linda – Seventh-day Adventists – Sabbath (day off); social capital; physical activity; nutrition  Genetics – Epi-genetics Gene-environment interaction

51  Income  Sense of belonging, social connectedness  Physical activity  Nutrition  Moderate wine

52  How do we get people to sustain or improve health behaviours over the life course?

53  Increase confidence to make a change (efficacy) involves getting people to be introspective about health  Must keep messages simple but potent  Notion of “health credit” – investments into health multiply and carry forward

54  Innovations Diffusion – lifestyle change through natural networks (Rogers, 1983)  Mass Media – more effective in creating knowledge of innovations and agenda setting  Interpersonal Channels – better in changing attitudes & behaviour  Health Promotion

55  Interactive, tailored designs are more effective because more engaging, higher expectations, and motivational  Higher levels of fitness (Hurling et al., 2006)  Interactive cardiovascular interventions showed improved quality of life (Delgado et al., 2003)

56  ParticipAction program – between 1971 and 2000, it was run on less than 1 million per year  Being reinvented  Canada’s Physical Activity Guide to Healthy Active Living (1998)  Older adult version (1999)

57  Integrated Pan-Canadian Healthy Living Strategy (2002)  $300M over 5 years  Population health approach – Phase One targets physical activity, eating habits and healthy weights

58  Many provinces have their own health promotion platforms to motivate Canadians to lead healthier lives:  ActNow BC/2010 Olypics  Active2010 (Ontario)  Healthy U (Alberta)  Saskatchewan in Motion

59  Four Cornerstones:  Age Friendly Communities  Mobilize and Support Volunteerism  Promote Healthy Lifestyles  Support Older Workers
