Data from: 8-year trends in physical activity, nutrition, TV viewing time, smoking, alcohol and BMI: a comparison of younger and older Queensland adults

Lifestyle behaviours significantly contribute to high levels of chronic
disease in older adults. The aims of the study were to compare the
prevalence and the prevalence trends of health behaviours (physical
activity, fruit and vegetable consumption, fast food consumption, TV
viewing, smoking and alcohol consumption), BMI and a summary health
behaviour indicator score in older (65+ years) versus younger adults
(18-65 years). The self-report outcomes were assessed through the
Queensland Social Survey annually between 2007-2014 (n=12,552). Regression
analyses were conducted to compare the proportion of older versus younger
adults engaging in health behaviours and of healthy weight in all years
combined and examine trends in the proportion of younger and older adults
engaging in health behaviours and of healthy weight over time. Older
adults were more likely to meet recommended intakes of fruit and vegetable
(OR=1.43, 95%CI=1.23-1.67), not consume fast food (OR=2.54,
95%CI=2.25-2.86) and be non-smokers (OR=3.02, 95%CI=2.53-3.60) in
comparison to younger adults. Conversely, older adults were less likely to
meet the physical activity recommendations (OR=0.86, 95%CI= 0.78-0.95) and
watch less than 14 hours of TV per week (OR=0.65, 95%CI=0.58-0.74).
Overall, older adults were more likely to report engaging in 3, or at
least 4 out of 5 healthy behaviours. The proportion of both older and
younger adults meeting the physical activity recommendations (OR=0.97,
95%CI=0.95-0.98 and OR=0.94, 95%CI=0.91-0.97 respectively), watching less
than 14 hours of TV per week (OR=0.96, 95%CI=0.94-0.99 and OR=0.94,
95%CI=0.90-0.99 respectively) and who were a healthy weight (OR=0.95,
95%CI=0.92-0.99 and OR=0.96, 95%CI=0.94-0.98 respectively) decreased over
time. The proportion of older adults meeting the fruit and vegetable
recommendations (OR=0.90, 95%CI=0.84-0.96) and not consuming fast food
(OR=0.94, 95%CI=0.88-0.99) decreased over time. Although older adults meet
more health behaviours than younger adults, the decreasing prevalence of
healthy nutrition behaviours in this age group needs to be addressed.
