By applying latent class model on the data of Chinese Longitudinal Healthy Longevity Study 2018, this paper analyzes the lifestyle patterns and the impacts of socio-economic status on lifestyle patterns among the older adults in China. Results show that the lifestyle patterns of the older adults in China can be divided into 4 types, which could be characterized as “lowstandard”“healthy”“mixed” and “risky” lifestyle, while the “lowstandard” type is the most distinguished lifestyle pattern of the older adults in China. The impacts of socioeconomic status on lifestyle patterns are not only significant by itself but could also change with age with different mechanisms. In the disadvantaged socioeconomic groups of older adults, the beneficial effects of socioeconomic status could be offset by ageing. However, in the advantaged socioeconomic groups of older adults, socioeconomic status could offset the adverse effects of ageing. This phenomenon is interpreted as “convergence at lower levels while divergence at higher levels” in this study. Finally, based on the research findings, this paper provides implications for promoting a healthy lifestyle among the older adults in China.

Based on data of new generation derived from the dynamic monitoring survey of migrants in 2011 in China and the theoretical perspectives of intergenerational accumulation and inheritance of family resources, this article investigates the influence of parental outworking experience on the employment status of the newgeneration migrants. Results show that the intergenerational inheritance of the parental outworking experience has an important direct or indirect impact on the employment status of the newgeneration migrants. Specifically, in the employment competition of the labor market, as ascriptive factors, the intergenerational inheritance of the parental outworking experience can indirectly change the employment opportunities of the newgeneration migrants by their personal migration experience, such as improving their employment disadvantage due to insufficient accumulation of their stay or experience. The intergenerational inheritance of the outworking experience of both parents can directly and effectively promote their nonemployed employment status. With the same personal, family, migration characteristics and the same work and security conditions, the intergenerational inheritance of the outworking experience of both parents directly improves the possibility of their dissatisfaction with the present work.

Drawing upon data from the 2010 Sample Survey of the Research of Theory and Practice of Peasant Workers’ Rights and Interests Protection conducted in Pearl Rver Delta and Yangtze River Delta，this paper examines patterns and determinants of mental health of peasant workers in the context of intergenerational difference，focusing on the impact of intergenerational difference on mental health of peasant workers by comparing the new generation with the old generation migrant workers. Results suggest that the impact of intergenerational difference on mental health of peasant workers involves major cohort effect in addition to age effect. Factors inside and outside workplace and social psychology have significant effect on the mental health of peasant workers，which are apparently different between the new and the old generation migrant workers. Life course and cohort effect perspectives are fundamentally important to deal with issues related to the new generation migrant workers for their integration into the cities.

Drawing on survey data from "Theoretical and Practical Research on Peasant Laborers’ Rights and Interests" in 2010,and based on age and experience of left-behind or migration in childhood,this paper identifies the second-generation peasant-workers who are deeply affected by parental labor migration,and compare their various characteristics.It shows that the characteristics of the second-generation peasant-workers is largely associated with their experiences of out-migration or left-behind in childhood.They are more likely to be "the amphibious persons" who do not benefit from the intergenerational transmission of labor migration between rural areas and cities,and consequently less likely to identify themselves being residents of the destination.The implication of such findings is that more attention should be paid to migrant and left-behind children and the second-generation peasant-workers with experience of migration or left-behind in childhood.Additionally,it is necessary to establish a system collecting prospective longitudinal data for migrant and left-behind children or retrospective longitudinal data for second-generation peasant-workers.

Various problems related to migrant or left-behind children are largely associated with family patterns and children’s living arrangement.Using data from a 2006 survey of migrant workers in Pearl River Delta,this paper explores determinants of migration probability of children of migrant workers.Results show that being migrant or being left-behind is significantly associated with children’s age,rural social support,migration distance and living status of their parents in the cities.The decision of being migrant or being left-behind is a rationale choice of children’s parents,which is also determined by institutions at the national and local level.Consistent with the "pull-push" theory of migration,migration of children of migrant workers is an outcome of the combination of the pulling factors at rural areas and the pushing factors at the urban areas,while also being a trade-off decision of their parents.
