Psychological distress, psychosocial factors, and physical inactivity among older women and men in Sweden: a...

Physical inactivity is a major public health concern worldwide. Psychological distress is linked to physical inactivity, which increases the risk of several diseases. Women tend to be more physically inactive than men. Moreover, physical inactivity increases with age in both sexes. Therefore, this study aimed to investigate the association between psychological distress and physical inactivity in adults aged ≥ 65 years, the role of psychosocial factors and explore sex-based differences.

This study included 14,213 older adults, comprising 7,069 women (52%) (median age = 75 years), who responded to a survey questionnaire sent to a random population sample in Mid-Sweden in 2022. The response rate in the population aged ≥ 65 years was 61%. The association between psychological distress as defined by the Kessler-6 and physical inactivity (< 150 min/week of physical activity) was analyzed using binary logistic regression, adjusting for sex, age, country of birth, educational level, and psychosocial factors.

Overall, 30% of the participants reported psychological distress, and 45% were physically inactive. Psychological distress and physical inactivity were significantly associated (p < 0.001), being more common among women (p < 0.001). In the fully adjusted model, the Odds Ratio (OR) for physical inactivity was 1.46 (95% confidence interval (CI) 1.43-1.50) for women and 1.70 (95% CI: 1.65-1.74) for men regarding moderate psychological distress and 2.87 (95% CI: 2.72-3.04) for women and 2.43 (95% CI: 2.28-2.58) for men regarding serious psychological distress. Not participating in social activities in the last 12 months was associated with physical inactivity in both women and men.

Psychological distress is significantly associated with physical inactivity among older adults. Participation in social activities was identified as an essential factor in addressing physical inactivity. Social connections and physical inactivity are important factors to consider when supporting older adults' mental health. Public health interventions should promote and raise awareness of physical and mental health as well as the social dimensions of aging, while also considering age and sex-based differences.
