Elderly's Homesickness: Development of Elderly Homesickness Questionnaire.

Introduction: Homesickness is a result of migration, and is related to adjustment difficulties and health problems, as well as clinical disorders. The aim of this study was to measure and explore the homesickness of Chinese elderly. Methods: A total of 355 non-local Chinese elderly in Shenzhen were recruited to measure demographic information and homesickness. and tested for reliability and validity. Patterns and influences of homesickness among Chinese elderly were explored through latent profile analysis and One-way ANOVA on the basis of EHQ. Results: A three-factor structure was verified in the 19-item elderly homesickness questionnaire (EHQ), namely "positive contact", "refusal to separate" and "homesickness behavior". The EHQ reports high validity and reliability. Chinese elderly had a high degree of homesickness, and homesickness among Chinese elderly varied significantly across variables such as age, occupation, and education level. Four homesickness patterns were found in Chinese elderly, named low homesick group, moderate homesick group, middle-high homesick group, and high homesick group. Coming from rural/urban areas and living with grandchildren are factors that affect classification. Conclusion: The present study reveals the high validity and reliability of the EHQ among Chinese elderly. The Chinese elderly reported high levels of homesickness, which varied significantly across levels of demographic factors. Four patterns of homesickness were found among the Chinese elderly, coming from rural/urban areas and living with grandchildren are the factors that affect classification. There may be a masking of the male contribution to the main effect due to the larger female sample.

The Associations of Meteorological and Environmental Factors with Memory Function of the Older Age in Urban Areas.

Individual, meteorological, and environmental factors are associated with cognitive function in older age. However, little is known about how meteorological and environmental factors interact with individual factors in affecting cognitive function in older adults. In the current study, we used mixed effects models to assess the association of individual, meteorological, and environmental factors with cognitive function among older adults in urban areas. Data from 2623 adults aged 60 to 91 years from 25 provinces (or autonomous regions/municipalities) from the China Family Panel Studies (CFPS) were used. We used the memory test in CFPS to measure memory function, while meteorological data from the daily climate data set of China's surface international exchange stations, and the traffic and greening data compiled by the National Bureau of Statistics (NBS) of China, were used to assess meteorological and environmental factors. The ICC of the empty model indicated that 7.7% of the variation in memory test scores for the older adults was caused by provincial characteristics. Results showed that the temperature and relative humidity of provinces moderated the effect of gender on the memory function for the older urban adults. Specifically, in the high temperature areas, memory scores for females were higher than those of males, and in the middle humidity areas, memory scores were also higher for the females than those of males. This study explained how meteorological and environmental factors played roles in influencing demographic factors on memory function among older adults. Further research is needed to better define the role and potential mechanism of this moderation.

The Impact of Early Neighborhood Cohesion, and Its Mechanism, on Cognitive Function in Later Life.

Objectives: This study aimed to explore the impact of early neighborhood cohesion, and its mechanism, on cognitive function in later life. Methods: In total, 10,727 Chinese elderly, aged 60-90, forming two datasets (2014 and 2018) from the China Health and Retirement Longitudinal Study (CHARLS) were used as a sample. Childhood neighborhood cohesion was measured by the extent of how much neighbors were willing to help and how close-knit neighbors were. Mini-Mental State Examination (MMSE) and Center for Epidemiologic Studies Depression Scale (CESD-10) were used to assess the cognitive functions and depression of the elderly. We used a structural equation model to examine the relationship between early neighborhood cohesion and late-life cognitive function and conducted bootstrapping analyses to assess the mechanism. Results: Cognitive function was positively predicted by childhood neighborhood cohesion (ß = 0.06, p < 0.001), and cognitive function of the elderly were also positively predicted through the mediating effects of childhood friendships, which included depression and social activity participation as two chain paths. Conclusion: The findings suggest that childhood neighborhood cohesion positively predicts cognitive function among elderly people through the mediating roles of childhood friendship, depression, and social activity engagement. Childhood neighborhood cohesion is correlated with better childhood friendships, then to fewer depression symptoms and greater elderly social activity participation, and finally to better cognitive functions in the elderly.
