Background: Metabolic dysfunction is a major determinant in the progression of fatty liver disease. It is pivotal to evaluate the metabolic status and subsequent transition in fatty liver population and to identify the risk of subclinical atherosclerosis. Methods: The prospective cohort study included 6260 Chinese community residents during 2010–2015. Fatty liver was determined as hepatic steatosis (HS) by ultrasonography. Metabolic unhealthy (MU) status was defined as having diabetes and/or ≥ 2 metabolic risk factors. Participants were categorized into 4 groups according to the combination of metabolic healthy (MH)/MU and fatty liver status (MHNHS, MUNHS, MHHS and MUHS). Subclinical atherosclerosis was assessed by elevated brachial-ankle pulse wave velocity, pulse pressure and/or albuminuria. Results: 31.3% of the participants had fatty liver disease and 76.9% were in MU status. During a 4.3-year follow-up, 24.2% of participants developed composite subclinical atherosclerosis. Multivariable adjusted odds ratios for composite subclinical atherosclerosis risk were (1.66 [1.30–2.13]) in MUNHS group and (2.57 [1.90–3.48]) in MUHS group. It seemed that participants with fatty liver disease were more prone to be remained in MU status (90.7% vs.50.8%) and less likely to regress to MH status (4.0% vs. 8.9%). Fatty liver participants progressed to (3.11 [1.23–7.92]) or maintained MU status (4.87 [3.25–7.31]) significantly impelled the development of the composite risk, while regressing to MH status (0.15 [0.04–0.64]) were more intended to mitigate the risk. Conclusions: The current study emphasized the importance of assessing metabolic status and its dynamic changes, especially in the fatty liver population. Regressing from MU to MH status not only benefited the systematic metabolic profile but also ameliorated future cardiometabolic complications. [ABSTRACT FROM AUTHOR]

Objectives Momentary solitude (the objective state of being alone) has a strong association with negative affective experiences in older people, but little is known about how the role of social relationship characteristics on relationship between momentary solitude and affect. We examined the momentary association between momentary solitude and negative affect (NA), and whether such association was moderated by the structural and functional aspects of social relationships. Methods A sample of 153 late-middle-aged and older adults were recruited and provided a total of 6,742 ecological momentary assessment surveys, of which momentary solitudes were reported for 1,885 (28%) surveys. Hierarchical linear model was used to examine how social networks and social support moderated the association of momentary solitude with NA experiences. Results The association of momentary solitude with NA experiences was significant among middle-aged and older adults (b = 0.025, SE = 0.008, p <.01). Family networks had the main effect on NA. Perceived social support buffered against increased NA in momentary solitude: Individuals with a higher level of perceived support reported fewer increases in NA during momentary solitude than those perceiving a lower level of support. Discussion Momentary solitude was experienced less negatively for middle-aged and older persons embedded in a context of higher levels of perceived social support. Practitioners need to pay more attention to the promotion of social resources when delivering programs to improve the subjective well-being of late-middle-aged and older adults.

Frailty is a pervasive symptom among the older population, and social participation is a beneficial factor of late‐life well‐being. However, studies on the bidirectional association between social participation and frailty are limited. This study examined the cross‐sectional and lagged associations of social participation and frailty. The analytic sample contained 6865 community‐dwelling older adults, with 21,141 observations, from the first four waves (2011–2018) China Health and Retirement Longitudinal Study (CHARLS). Frailty was measured by the Frailty Index (FI). Social participation was measured by the accumulation of the frequencies of six social activities. Random intercept two‐level models were used to analyse the concurrent and lagged association between social participation and frailty. The results showed significantly cross‐sectional associations between higher levels of frailty and lower levels of social participation in the same wave. Moreover, there was a lagged association of social participation in the prior wave with the current frailty (b = −0.001, SE = 0.001, p = 0.028), and frailty in the prior wave with the current social participation (b = −0.634, SE = 0.088, p < 0.001) even after adjusting for sociodemographic characteristics, and frailty or social participation in the prior wave. The bidirectional associations between social participation and frailty imply the necessity of enhancing social participation to prevent or slow the frailty progression, and improving the physical and social environment to reduce social participation restrictions imposed by frailty status.
