This systematic review synthesizes observational studies on the relationship between ageism and health. We searched 10 electronic databases and included 67 articles. The operationalization of ageism in these studies can be classified into three constructs: age stereotype, self-perceptions of aging, and age discrimination. Most ageism measures were used within a single study, and many lacked information about psychometric properties. Seven health domains—disease, mortality, physical/functional health, mental health, cognitive function, quality of life, and health behavior—have been used as outcomes. Evidence supports a significant association between ageism and health, particularly between self-perceptions of aging and health. Nine studies report moderators, which helps to identify those more vulnerable to negative effects of ageism and inform the development of interventions. The review suggests that the literature has examined limited dimensions of ageism, and that developing valid and reliable instruments for ageism-related concepts is a priority.

The governmental responses to coronavirus disease 2019 (COVID-19) pandemic, including the approach, interventions, and their associated effectiveness, vary across social, cultural, political, and institutional contexts. In China, the Wuhan lockdown significantly reduced the transmission of COVID-19 throughout the country. Chinese central and local governments' responses to disease containment and mitigation were uniform in policymaking but implemented differently across local governing contexts. This study examines the variation in the effects of human mobility restrictions on inter-provincial migration flow during the COVID-19 outbreak in China. The results show that mobility restrictions reduced the inter-provincial in-migration flow by 63%, and the out-migration flow by 62% from late January to early May in 2020, but the effects varied significantly across provinces. Further, the negative effects of mobility restrictions on province's outflow migration were greater in provinces where local governments had higher levels of social media involvement, greater public security spending, and longer duration of first-level response to public health emergencies. The finding provides important insights for understanding China's local governmental responses to mobility restrictions and their effects on the spread of COVID-19. The coronavirus disease 2019 (COVID-19) emerged in Wuhan, Hubei Province, China, in early December of 2019, and rapidly evolved into a global pandemic. In China, a range of interventions were implemented to CONTACT Zhen Liu

Using hierarchical age–period–cohort growth curve models, this study assesses changes in gender disparities in housework time across Chinese adults’ life course and across different birth cohorts. The results revealed three key findings. First, inconsistent with convergence theory, the Chinese family is still a male-dominated but male-absent family, with women still doing the majority of domestic work and showing no signs of decline with age. Second, as they age, Chinese women and men present diverging tendencies toward time spent on housework: Women tend to dedicate more time to it, and men less, resulting in a widening gender gap in housework with age. Third, although recent cohorts present lower levels of housework time than previous cohorts, this is because men from recent cohorts are doing less housework, while their female counterparts are doing almost as much as women from earlier cohorts.
