Barriers to healthy lifestyle behaviours and adherence to physical activity and dietary guidelines by older Australians: A descriptive analysis

Abstract

Objective: To examine adherence to physical activity (PA) and dietary guidelines, explore barriers to healthy lifestyle behaviours, and determine any associations with lipid-lowering drug therapy (LLT). Design: Cross-sectional analysis of self-reported PA using the International Physical Activity Questionnaire for Elderly (IPAQ-E), diet using the Australian Short Dietary Screener (Aus-SDS), and perceived barriers to healthy PA and dietary behaviours. Setting: Australia Participants: A convenience sample of 110 community-dwelling Australian adults aged ≥70 years. Results: Descriptive statistics and Pearson's χ2 were used to analyse adherence to guidelines and lifestyle barriers. Of 110 adults (mean age 76.8 ± 4.5y), 51.8% met PA guidelines, and none met all five dietary guidelines. Lipid-lowering drug therapy users engaged in less weekly PA (median 155, IQR = 70, 370 min) than non-users (median 420, IQR = 210, 675 min). Dietary intake did not differ by LLT status. Mobility and health concerns (68.1% vs 23.7%), and motivation (79.2% vs 36.8%) were more common barriers to PA among LLT users compared with non-users (p < 0.001). Perceived dietary barriers did not differ by LLT use. Conclusion: Half the study population met PA guidelines; however, none met all dietary guidelines. In older adults, targeted interventions addressing common barriers to achieving healthy lifestyles and reducing the risk of chronic disease are needed, especially among LLT users.
