Dimensions of the diet-exercise relationship in later life: A qualitative study.

OBJECTIVE: Diet and physical activity are two lifestyle behaviours that are critical for healthy ageing. The aim of this study was to explore how older adults negotiate dietary and physical activity decisions to identify areas of intersection between these two behaviours and inform health promotion interventions targeting both diet and exercise. METHODS: This exploratory study utilised a novel data collection approach that involved lay interviewers recruiting their peers to (i) participate in two interviews over a period of six months and (ii) make notes on their thoughts relating to diet and physical activity. Participants were 75 adults aged 60+ years in Western Australia (n = 64 females). RESULTS: Three primary themes were identified: (i) the importance but difficulty of achieving energy balance; (ii) issues relating to managing food intake before, during, and after physical activity; and (iii) reciprocal opportunities for eating and physical activity. CONCLUSIONS: Diet and physical activity are linked in complex ways, highlighting the need for multi-factorial interventions. IMPLICATIONS FOR PUBLIC HEALTH: When developing communications strategies designed to encourage older people to both improve their diets and increase their physical activity, consideration could be given to leveraging existing perceived alignments between healthy eating and being active.

Brief Report: A Latent Class Analysis of Guideline Compliance Across Nine Health Behaviors.

BACKGROUND: Prevalence figures for health-related behaviors disguise the existence of behavioral clusters. A growing body of work indicates the potential effectiveness of using simultaneous (versus sequential) approaches to targeting health-related behaviors to make deeper inroads into addressing non-communicable diseases. To inform future interventions designed to simultaneously address multiple risk factors, the aim of the present study was to identify behavioral clusters including nine behaviors relating to smoking, alcohol consumption, nutrition, physical activity, and sleep. METHOD: A latent class analysis was applied to a nationally representative sample of 1849 adult Australians. RESULTS: Of the four identified segments, one was characterized by a relatively healthy behavioral profile and another demonstrated poor results across multiple lifestyle domains. The other two groups comprised individuals who demonstrated healthy behaviors in some domains (e.g., substance use) but not in others (primarily physical inactivity and junk food consumption, respectively). CONCLUSIONS: Results suggest the opportunity to encourage individuals in the latter two groups to build on existing positive behaviors to achieve greater overall compliance with health recommendations. Particularly intensive interventions are likely needed for those in the unhealthiest group to address the potentially reinforcing effects of their multiple unhealthy behaviors.
