To explore the effects of leisure activities (LA), dietary diversity score (DDS) and body fat levels(BMI, WHtR, WC)on the prevalence of physical-psychological-cognitive comorbidities in the elderly.
Based on the CLHLS—2018 data, the comorbidities of the elderly aged 65 and above from 2017 to 2019 were described. The Chi-square and t test were used to compare differences between groups, and multi-factor logistic regression and restricted cubic splines were used to explore the effects of leisure activities, dietary diversity and body fat indicators on the prevalence of comorbidities in the elderly.
A total of 12 047 subjects were included in the study, and the prevalence of comorbidities was 42.60%, with more females than males. Multivariate regression showed that compared with the Q1 group of LA, the OR and 95% CI of the Q3 group: 0.575 (0.513-0.645); The DDS group OR and 95% CI of the Q3 group: 0.853 (0.774-0.939), Ptrend=0.002; Among body fat indicators, only BMI has a significant association. The risk of disease in group Q3 is 1.195 times that of group Q1 (95% CI: 1.065-1.342), Ptrend=0.003. Further nonlinear tests indicate that LA and WHtR have non-linear relationships with comorbidities (both Pnon-linear< 0.05).
Reasonably controlling body fat levels, increasing engagement in leisure activities, and improving dietary diversity may be effective measures to prevent physical-psychological-cognitive comorbidities in the elderly.
