The relationship between oral status and healthy aging in Chinese older adults: A community cohort study.

OBJECTIVES: In recent years, there has been a growing academic interest in investigating the determinants of healthy aging. The main objective of this study was to investigate the association between oral status, as defined by tooth loss and denture use, and healthy aging among Chinese older adults over a four-year duration. METHODS: The data were derived from the 2014 and 2018 waves of the Chinese Longitudinal Healthy Longevity Survey. Descriptive statistics and multivariate logistic regression analysis were employed for statistical analysis. RESULTS: The results suggest that older adults with ≥20 natural teeth have a higher likelihood of experiencing healthy aging compared to those with fewer than 20 natural teeth. In the fully adjusted model, only older adults with ≥20 natural teeth demonstrated a higher rate of healthy aging compared to those with 0 natural teeth, with an OR (95% CI): 2.09 (1.54-2.84). CONCLUSIONS: These results highlight the importance of maintaining ≥20 teeth for promoting healthy aging among Chinese older adults. Furthermore, wearing dentures can, to varying degrees, mitigate the adverse effects of tooth loss on healthy aging. Rehabilitative interventions, such as the utilization of dentures and other clinical strategies, play a pivotal role in enhancing the oral health status of older individuals.

Amelioration and deterioration: Social network typologies and mental health among female domestic workers in China.

Previous quantitative studies on the effects of social network types on mental health have obtained inconsistent or conflicting results, due to problems such as sample selection bias or crude measurement of variables. In this study, we avoided these problems by using appropriate statistical methodology to examine the effect of various forms of social network on the mental health of a sample of 987 Chinese female domestic workers. Thus, we measured social network types in terms of both network attributes (friend networks and family networks) and interaction channels (face-to-face, telephone, and WeChat/QQ channels, where the latter are two popular online messaging platforms in China), and used the coarsened exact matching method to obtain a balanced sample. The results showed that social network typologies had positive and negative effects on the mental health of this sample of domestic workers, as evidenced by (1) In terms of network attributes, family networks were associated with improved mental health and friend networks were associated with worsened mental health; (2) In terms of interaction channels, the significant amelioration in mental health from family networks came from face-to-face interactions, the significant deterioration in mental health from friends networks came from telephone interactions, and in terms of other interaction channels, family networks and friends networks had no significant effect on mental health. Robustness tests indicated that these conclusions are reliable. We discuss the possible mechanisms of which different types of social networks influence mental health.

The Influence of Person-Job Fit on Health Status and Depression Among Chinese Domestic Workers: Mediating Effect of the Employer-Employee Relationship.

Domestic workers usually perform manual work in households. Unlike fixed work, their work tends to be individualized and atomized. Their person-job fit and relationship with employers might exert some influence on their health, both physical and psychological. This quantitative study explores the association between person-job fit, health status, and depressive symptoms among Chinese domestic workers by identifying the employer-employee relationship as a mediator. Data is collected from a survey of Chinese domestic workers conducted in four cities of Nanjing, Wuxi, Guangzhou, and Foshan (N = 1,003) in 2019. We test our theoretical model by conducting structural equation modeling. The results show that demand-ability fit is indirectly related to heath status and depressive symptoms via the employer-employee relationship. Need-supply fit is significantly associated with health status and depressive symptoms both directly (70% for health status and 72% for depressive symptoms, separately) and indirectly, via the mediating effect of the employer-employee relationship (30% for health and 28% for depressive symptoms, separately). Our findings suggest that appropriate policy and vocational training should be implemented to improve the health status of Chinese domestic workers.

Examining the impact of functional disability and cognitive impairment on mental health of Chinese elderly.

Depression and anxiety, as the two most prevalent psychiatric disorders, pose a huge challenge to the quality of life of the elderly. Using a sample of 7,721 elderly from the latest Chinese Longitudinal Health and Longevity Survey (CLHLS), the present study intended to explore the association between mental health and socioeconomic status, physical functional disability, and cognitive impairment among Chinese elderly by adopting multivariate logistic regression analyses. The results revealed that depression, anxiety, and their comorbidity are significantly higher in the elderly with instrumental activities of daily living (IADL) disability, cognitive impairment, financial strain, and living alone. Findings of the study will provide implications for policymakers, social workers, and individual caregivers to develop necessary intervention measures to improve the mental health of the elderly and promote successful aging.

Act Tough and Soft: Video Monitoring, Hongbao Gifts, and the Job Satisfaction of Domestic Workers.

There is a rapidly growing demand for domestic services among urban families in China. However, domestic work remains a low-status occupation with a high turnover rate. Focusing on the job satisfaction of domestic workers is useful to interpret this phenomenon. We investigate how the job satisfaction of domestic workers in China is affected by to two distinct labor control strategies used by their employers: the installation of video-monitoring devices in employers' homes (a "tough" control strategy), and the Chinese custom of giving monetary gifts, or "hongbao" (a "soft" control strategy). By analyzing data from surveys of domestic workers in four cities in China (N = 699), we find that video monitoring in employers' homes negatively impacts domestic workers' job satisfaction, and that hongbao gifts from employers significantly promote domestic workers' job satisfaction. The analysis of the causal mechanism based on a structural equation model suggests that video monitoring can increase the discrimination that domestic workers perceive, which in turn reduces their job satisfaction. In particular, we find that domestic workers' perception of discrimination completely mediates the effect of video monitoring on their job satisfaction. However, we also find that hongbao gifts significantly reduce domestic workers' perceptions of discrimination, and thus promote their job satisfaction; that is, the relationship between hongbao gifts and job satisfaction is partially mediated by discrimination. Our study provides a more comprehensive understanding of Chinese employers' labor control strategies and their effects on the job satisfaction of domestic workers.

Occupational Characteristics in the Outbreak of the COVID-19 Delta Variant in Nanjing, China: Rethinking the Occupational Health and Safety Vulnerability of Essential Workers.

The risk of contracting COVID-19 varies by occupation. Clarifying the occupational disparity in the infection risk is crucial to the prevention and control of the epidemic in the workplace. In late July, some new cases of COVID-19 were confirmed among cleaners working in Lukou International Airport in Nanjing, China. The infected cases rapidly increased and spread to many domestic cities in the following days. The present study traces the brief reports of epidemiological investigations among the confirmed cases released by the Nanjing government from 20 July to 2 August, and offers a descriptive analysis on the occupational distribution of these cases. Cleaners and other staff working in the airport were found to make up more than 40% of all cases. The overwhelming majority of the cleaner cases were confirmed in the first 7 days. The present study statistically ascertains that the airport cleaners were the initial sufferers and transmitters in this outbreak. They experienced occupational health and safety vulnerability on both individual and contextual levels, including workplace hazards, workplace safety policies, and lack of awareness and empowerment. Effective protection for essential workers and the strict surveillance of occupational health in the workplace is urgently needed.

Prediction of Epidemic Spread of the 2019 Novel Coronavirus Driven by Spring Festival Transportation in China: A Population-Based Study.

After the 2019 novel coronavirus (2019-nCoV) outbreak, we estimated the distribution and scale of more than 5 million migrants residing in Wuhan after they returned to their hometown communities in Hubei Province or other provinces at the end of 2019 by using the data from the 2013-2018 China Migrants Dynamic Survey (CMDS). We found that the distribution of Wuhan's migrants is centred in Hubei Province (approximately 75%) at a provincial level, gradually decreasing in the surrounding provinces in layers, with obvious spatial characteristics of circle layers and echelons. The scale of Wuhan's migrants, whose origins in Hubei Province give rise to a gradient reduction from east to west within the province, and account for 66% of Wuhan's total migrants, are from the surrounding prefectural-level cities of Wuhan. The distribution comprises 94 districts and counties in Hubei Province, and the cumulative percentage of the top 30 districts and counties exceeds 80%. Wuhan's migrants have a large proportion of middle-aged and high-risk individuals. Their social characteristics include nuclear family migration (84%), migration with families of 3-4 members (71%), a rural household registration (85%), and working or doing business (84%) as the main reason for migration. Using a quasi-experimental analysis framework, we found that the size of Wuhan's migrants was highly correlated with the daily number of confirmed cases. Furthermore, we compared the epidemic situation in different regions and found that the number of confirmed cases in some provinces and cities in Hubei Province may be underestimated, while the epidemic situation in some regions has increased rapidly. The results are conducive to monitoring the epidemic prevention and control in various regions.
