RESUMO
Objective To examine the relationship between electronic wearable device (WD) use and physical activity (PA) levels among older adults in the US. Methods Data were pooled from 3310 older adults from the 2019 and 2020 Health Information National Trends Survey. The explanatory variable was WD use, and the outcomes were weekly PA levels, resistance training, and sedentary time. Logistic regression was conducted to investigate the association between WD use and the reported outcome variables. Separate logistic models were also fitted to explore the relationship between WD use and physical activity outcomes among a subgroup of older adults with chronic conditions. Results A total of 14.4% of older adults reported WD use. Older adults who use WD were more likely to meet national guidelines for weekly levels of PA (odds ratio (OR) 1.60, 95% confidence intervals (CI) (1.10, 2.32); p = 0.015) and resistance strength training (OR 1.54, 95% CI (1.14, 2.09); p = 0.005) when compared with their counterparts not using WD. After restricting the analysis to those with chronic conditions only, WD use was only associated with a higher level of weekly strength training (OR 1.68, 95% CI 1.19, 2.38; p = 0.004). Conclusion WD use may be associated with increased physical activity among older adults, including those with chronic health conditions. Further studies are needed to examine the factors influencing the adoption and sustained use of WD in older adults.
RESUMO
OBJECTIVE: The aim of this study was to examine the impact of coronary heart disease (CHD) on health-related quality of life (HRQoL) among individuals taking aspirin, as well as to explore the potential association between stroke and CHD on HRQoL. METHOD: A total of 17,106 respondents aged 50 years and above who reported using aspirin on "some days" or "daily" were included in the analysis. Among them, 4,036 individuals had a history of coronary heart disease. We utilized the Chi-square test to assess the proportion of individuals with CHD who reported poor self-rated health and experienced poor HRQoL in four domains: physical health, mental health, physical and mental health combined, and the number of days limited by poor health. Logistic regression was employed to investigate the interaction between stroke and CHD concerning the quality of life. RESULT: Among adults aged 50 years and above using aspirin, those with CHD tended to be older (68.7 years ± 0.37 vs 66.6 ± 0.24), had a higher proportion of male respondents (60.0% vs 45.1%), and were mostly of white ethnicity (77.4% vs 76.2%). The group with CHD reported significantly poorer self-rated health compared to those without CHD (52.1% vs 25.6%, p<0.001), along with a higher prevalence of poor physical health (55.3% vs 42.7%, p<0.001) and poor mental health (50.2% vs 40.4%, p = 0.033) in comparison to aspirin users without CHD. However, there was no statistically significant association between stroke and CHD concerning the impact on all domains of quality of life (p>0.05). CONCLUSION: Our findings indicate that individuals aged 50 years and above with CHD who are using aspirin experience a lower quality of life in both the physical and mental health domains when compared to their counterparts without CHD. Furthermore, there was no significant interaction between stroke and CHD in relation to the impact on HRQoL in this study.
