Abstract

Background: This cluster randomised controlled trial aimed to determine if a 6- month home-based interventioncould improve the physical activity and dietary behaviours of adults aged 60 to 80 years living in retirement villageslocated in Perth, Western Australia.Methods: Participants (n = 363) from 38 retirement villages were recruited into the trial and allocated to theintervention (n = 197: 17 sites) or control (n = 166: 21 sites) group and were blinded. Previously validatedinstruments-Fat and Fibre Barometer and International Physical Activity Questionnaire, along with anthropometricmeasures (weight, height, waist and hip circumferences) and blood pressure were collected at baseline and 6 -monthtime period. Comparisons between intervention and control groups were undertaken pre- and post- intervention usingunivariate chi-square and t-tests. Multi-level mixed regression analyses were then conducted to ascertain the effects ofthe intervention on changes in the outcome variables over time and between groups.Results: A total of 139 (70.5%) intervention and 141 (84.9%) control group participants completed the program andpost-test assessments. The intervention group demonstrated significant increases in time (80 min more per week onaverage) devoted to moderate-intensity physical activity, engagement in strength exercises (from 23.7% to 48.2%),frequency of fruit consumed as well as fat avoidance and fibre intake scores, in addition to a 0.5 kg mean reduction inweight post program, whereas no apparent changes were observed in the control group. Mixed regression resultsfurther confirmed statistically significant improvements in weight loss (p p p = 0.012) by the intervention participants at post-test relative to their controls.Conclusions: Retirement offers a time to reassess lifestyle, and adopt positive health enhancing physical activity anddietary behaviours. This intervention was successful in improving weight, engagement in strength exercises,increasing levels of moderate-intensity physical activity and consumption of fruit among retirement villageresidents. Further investigation is needed on how to better engage retirement village managers in such programs.
