Associations of lifestyle with physical, hearing, visual, and mental functional impairments among older adults: Findings from two prospective cohort studies

Unraveling the associations between unhealthy lifestyle behaviors and mental health in the general adult Chinese population: A cross-sectional study

BACKGROUND

This study examined the cumulative risk of unhealthy lifestyle behaviors and the associations between overall lifestyle and common mental disorders (CMDs), insomnia, stress, health-related quality of life (HRQOL), and functional impairment. Additionally, the treatment preferences for managing CMDs and insomnia were examined.

METHODS

A survey was conducted on 1487 Chinese Hong Kong adults, assessing their lifestyle behaviors (i.e., diet and nutrition, substance use, physical activity, stress management, restorative sleep, social support, and environmental exposures), mental health-related outcomes, and treatment preferences via a vignette.

RESULTS

The findings revealed significant additive relationships between the number of 'worse' lifestyle domains and the risk of all outcomes. A healthier overall lifestyle was significantly associated with reduced risks of all outcomes (AORs = 0.88 to 0.93). Having healthier practices in diet and nutrition, substance use, stress management, restorative sleep, and social support domains were significantly associated with lower risks of all outcomes (AORs = 0.93 to 0.98), except that substance use was not significantly associated with stress. Physical activity was inversely associated with only depressive symptoms (AOR = 0.98), anxiety symptoms (AOR = 0.99), and stress (AOR = 0.99). Environmental exposures were not significantly associated with functional impairment but with all other outcomes (AORs = 0.98 to 0.99). Besides, lifestyle interventions (55 %) were significantly more preferred for managing CMDs and insomnia relative to psychotherapy (35.4 %) and pharmacotherapy (9.6 %).

CONCLUSIONS

Our findings underscore the importance of considering lifestyle factors when managing CMDs, insomnia, stress, HRQOL, and functional impairment, with a particular emphasis on adopting a multicomponent treatment approach.

Latent transition analysis to explore patterns of physical functional decline among older adults in China: A national 6-year longitudinal study

BACKGROUND AND AIMS

Multiple limitations often co-occur and accumulate, leading to subsequent function decline. However, there is a scarcity of longitudinal studies examining the progression of physical function among the general population of older adults in China. This study aimed to define typical physical function status and its change, which were characterized by the coexistence and accumulation of diverse limitations targeting a Chinese sample of older adults.

METHODS

This study used the three recent public data waves of the Chinese Longitudinal Healthy Longevity Survey during a 6-year follow-up period. 9765 individuals who were over 65 and participated in the 2011 survey were included. Latent transition analysis was used to identify the latent physical function status and explore the transition of older adults among different latent statuses.

RESULTS

Seven latent statuses of physical function were identified, with visual impairment and related limitations being particularly prevalent among older adults. Upper limb mobility appeared to be a differentiated indicator of physical functional status. Physical function decline mainly started with the limitations in squatting, carrying weights and walking, then to the status with intact upper limb mobility and hearing function only, or converted directly into the latter, then to complete dysfunction.

CONCLUSIONS

Our findings suggest some indicative limitations and critical steps in the process of functional decline among older adults. These results may provide insight for researchers and policymakers to develop tailored preventive and rehabilitation care and provide support for physically limited elderly according to their latent status and course of functional decline.
