Social relationships play an important role in mental health as well as suicidal ideation in later life. In contrast with the other well-established risk factors, despite an increasing number of related studies, no meta-analyses focusing on social relationships and late-life suicidal ideation have been published. Synthesis of data across the studies using different measurements of social relationships would allow for comparison of the effects on late-life suicidal ideation that have not been studied before. Therefore, we conducted a meta-analysis on the studies published between January 1, 2000 and November 31, 2016 extracted from 7 medical and social science databases. 31 studies with 83 estimates of Odds Ratios (“ORs”) on the associations between social relationships and late-life suicidal ideation were identified to compute effect sizes using a random-effect model. Sensitivity analyses were also performed to evaluate their heterogeneity and bias. Moderator analyses were further conducted to determine moderating factors of the associations. Eventually, across the 31 studies (203,152 participants), the overall random effect size was OR = 1.57(95% CI [1.40, 1.76]), indicating a 57% likelihood increase of suicidal ideation for elderly participants with discordant social relationships. The functional measures (OR = 1.77; 95%CI [1.48, 2.10]) of social relationships, however, were more predictive than structural measures (OR = 1.37; 95%CI [1.25, 1.51]). Among all the measures of social relationships, elderly mistreatment (OR = 2.31; 95%CI [1.81, 2.94]) had the strongest effect size, followed by perceived loneliness (OR = 2.24; 95%CI [1.73, 2.90]) and poorly perceived social support (OR = 1.59; 95% CI [1.37, 1.83]). The associations between social relationships and late-life suicidal ideation were moderated by country income levels, social-cultural context, study types, and various measurements of social relationships. More importantly, our study is the first meta-analysis to provide significant evidence for improving social relationships, especially in perceived bonds, is a promising strategy in reducing late-life suicide risks.

Libraries play a significant role in supplying educational and cultural services. They are important public spaces that can contribute to creating social equality by providing unlimited access to information and public spaces for the community. In this research both the traditional measures (supply-to-demand ratio and straight distance) and advanced measures (population-weighted average nearest network distance and population-weighted average two-step floating catchment area (2SFCA) score) are used to assess spatial inequity in the distribution of libraries throughout Hong Kong. How accessibility has been changed after the introduction of two strategies for improvement (community and mobile libraries) is also examined, as are spatial demographic and socioeconomic characteristics associated with library provision. The results indicate that there is a substantial heterogeneity of library provision in Hong Kong. Community and mobile libraries have significantly improved the library provision in several areas, although spatial inequality remains. Areas with demographic and socioeconomic groups with lower accessibility to library services were further identified. Data at multiple geographical scales were used, and consistent findings were obtained, confirming the robustness of the results. [ABSTRACT FROM AUTHOR]

In considering the influence of the neighborhood environment on cognitive function, little research has looked beyond the individual factors. Here, we conducted a study on 21,008 older adults aged 65 years and above in Hong Kong to examine the cross-sectional associations of neighborhood economic disadvantage, recreational resources, walkability, library accessibility and physical activities on cognitive function and dementia. Both smaller and larger census tracts were adopted as proxies for neighborhoods. Using multilevel regression, neighborhood economic disadvantage was found to be associated with cognitive decline, net of individual features. This association was not explained by neighborhood built environment. Recreational environment was not a significant factor for older adults' cognitive function while library accessibility was. Neighborhood walkability was only related to dementia but not the cognitive function score. Physical activity can partly explain the relationship between neighborhood environment and cognitive function. No significant interaction effect was identified except on the educational level and neighborhood library accessibility. To conclude, late life residential environments are important contexts for aging. Aging-in-place interventions in Hong Kong should thus address neighborhood poverty, improve accessibility of libraries and walkability to reduce future risks of cognitive decline.

With some exceptions, literature has consistently shown that divorced populations are at higher risk for suicide than married ones. Here we make use of coefficients of aggravation (COAs), suicide rate ratios of the divorcees over the married, to study patterns of COAs and test the contribution of international sociocultural factors and gender to the relationship between divorce and suicide. We conducted a systematic search of electronic databases to identify ecological studies reporting suicide rates and ratios of those rates within different marital statuses between Jan 1, 2000 and Dec 31, 2013. In total, ten studies consisting in suicide statistics of eleven countries/areas were selected. Using random-effect modeling, we noted that the pooled COA for men and women were 3.49 (95% CI 2.43–4.56) and 3.15 (95% CI 1.74–4.56), suggesting both divorced men and women exhibited a greater risk of suicide than their married counterparts. Subgroup analyses revealed that COAs in Asian countries are significantly higher than those in non-Asian ones. Among the sociocultural measures retrieved from the HOFSTEDE index and the World Values Surveys, we noted significant associations between COA and four measures, including the individualism–collectivism score, the long-term orientation scores, the survival/self-expression score, and the gender inequality indices. The magnitudes and the directions of the associations however differ by sex. The results confirm that overall divorced people have an aggregate higher suicide risk than married ones. The method used in our research could reveal what cultural indicators are exerting effect on the relationship between divorce and suicide risk, which might change with sociocultural transition. More investigation into the relationships and then the construction of culturally appropriate suicide prevention policy is recommended. [ABSTRACT FROM AUTHOR]
