Diabetes mellitus and functional limitations among older adults: Evidence from a large, representative Ghanaian aging study
International audienceObjectives: Literature linking diabetes mellitus (DM) to functional status is limited in low- and middle-income countries. Importantly, factors influencing this association are even less understood. This study aims to examine the association of DM with functional limitations (FL) in older adults and to identify potential factors influencing this association. Methods: In a cross-sectional analysis, we examined the association between DM and basic and instrumental activities of daily living-related FL in 1201 adults aged ≥50 years from the Aging, Health, Psychological Well-being, and Health-seeking Behavior Study. DM was defined as a self-report of physician diagnosis. The associations were assessed using hierarchical regression estimates and bootstrapping technique via the Hayes PROCESS macro program. Results: The prevalence of DM and FL was 10.1% and 36.1%, respectively, with OR = 2.50 (95%CI = 1.59–3.92) after accounting for sociodemographic factors, smoking, alcohol use, self-rated health, loneliness, and sleep quality. After full adjustment, polytomous regressions showed that the association of DM with FL increased with the number of FL (i.e., OR = 1.60 for 1–2, OR = 1.88 for 3–5, and OR = 2.0o for >5 FL compared with no FL). However, this association was attenuated after controlling for physical activity (OR = 2.06, 95%CI = 1.28–3.31), hypertension (OR = 1.87, 95%CI = 1.14–2.99), stroke (OR = 1.82, 95%CI = 1.20–2.93), and pain facets (OR = 1.80, 95%CI = 1.04–3.02). PA thus mediated 40.39% of the DM-FL association. Conclusions: In this representative study, older adults with DM showed higher odds for FL, and this association was partially explained by physical activity and health variables. Investing in a holistic management approach might be helpful for public health planning efforts to address DM-induced FL in old age
Mobility limitations and emotional dysfunction in old age: The moderating effects of physical activity and social ties
International audienceBackground: This study aims to examine the association between mobility limitations and emotional dysfunction among older Ghanaians and evaluate the buffering effect of physical activity (PA) and social ties in this association. Methods: The analysis included 1201 adults aged ≥50 from the 2016-17 Aging, Health, Psychological Well-being, and Health-seeking Behavior study. The Medical Outcomes Study Short Form-36 (MOS SF-36) assessed mobility limitations and emotional dysfunction. We measured PA using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Hierarchical OLS regressions were performed to evaluate the hypothesized direct and interactive relationships. Results: The mean age of the sample was 66.2 (SD = 11.9), and 63.3% were women. After full adjustment for potential confounders, OLS regressions found that mobility limitations increased the risk of emotional dysfunction (β = 0.113, p = 0.004). Moreover, social ties (β = −0.157, p < 0.001) and PA (β = −0.096, p < 0.001) were independently and negatively associated with emotional dysfunction. We finally found a significant effect modification of the association of mobility limitations with emotional dysfunction by PA (β = −0.040, p < 0.002) and social ties (β = −0.013, p = 0.013). Conclusions: Mobility-enhancing strategies such as engagement in positive behavioral choices, focusing on regular PA, and maintaining resourceful interpersonal social networks can mitigate the impact of mobility limitations on emotional dysfunction in later life
