“…Respondents were asked to indicate how often during the past 12 months they had helped their neighbors who do not live with them and who did not pay them for that help ( almost daily ; almost weekly ; not regularly ; never ). Following previous studies [3, 4, 15, 17, 34, 35], the responses were categorized into a dichotomous indicator contrasting those with high social reciprocity (almost daily or almost weekly) to those with low social reciprocity (not regularly or never). Neighborhood social reciprocity was indicated as the proportion (ratio) of persons in the respondent’s neighborhood that reported high social reciprocity.…”

Background This study aims to investigate the mechanisms through which neighborhood social reciprocity influences older adults’ mental health in China. Methods This study used data from the 2011–2015 waves of the China Health and Retirement Longitudinal Study. It estimated the effects of neighborhood social reciprocity on older adults’ mental health and tested the mediating effects of the frequencies of physical activity, social interaction with neighbors, and volunteering experience. Results The results indicated that more neighborhood social reciprocity related to better mental health. The effects of the three mediators were statistically significant and enhanced mental health. In addition, the effects of the mediators were strengthened by neighborhood social reciprocity, and vice versa. Conclusions In China, neighborhood social reciprocity influenced older adults’ mental health directly and through the mechanisms of the frequencies of physical activity, social interaction with neighbors, and volunteering experience.

“…Depression not only reduces life quality (Ruo et al, ) but also increases the risk of chronic physical illness (Farrokhi, Abedi, Beyene, Kurdyak, & Jassal, ; Hare, Toukhsati, Johansson, & Jaarsma, ; Moussavi et al, ; Psaltopoulou et al, ; Van der Kooy et al, ). Preventing and reducing the risk of depression is therefore a key public health concern especially for older people (Helbich et al, ; Niles & O'Donovan, ; Wang, Liu, et al, ; Wang, Lu, et al, ). Compared to young people, older people spend more time in their neighbourhoods due to retirement and functional restriction (Liu et al, ; Wang, Feng, Xue, Liu, & Wu, ; Wiles et al, ; Wiles, Leibing, Guberman, Reeve, & Allen, ) and neighbourhood environment may play an important role in their daily life.…”

Previous research has found a negative linkage between neighbourhood social participation and depressive symptoms in Western countries, but the cross‐sectional design of these studies limits the ability to infer causality. Little attention has been paid to socio‐psychological pathways linking neighbourhood social participation to depressive symptoms among older adults in China. This study aimed to examine the impact of neighbourhood social participation on depressive symptoms among older adults in China. It also further explored the mediating roles of physical activity, social contact among neighbours, and contact with own children in the relationship between social participation and depressive symptoms. Data obtained through three waves (2011, 2013, and 2015) of the China Health and Retirement Longitudinal Study were used. The sample consisted of 10,105 individuals aged 60 and above and 24,623 person‐year records captured during these three waves. Depressive symptoms were assessed using the Center for Epidemiology Studies of Depression scale. Results showed that respondents' depression decreased with an increasing level of neighbourhood social participation, more time spent on physical activities, and a higher frequency of contact with neighbours and with own children. These factors were found to partly mediate the relationship between neighbourhood social participation and depression. The negative relationships between social contact and depression and contact with own children and depression were both strengthened by neighbourhood social participation. In conclusion, physical activity, social contact among neighbours and contact with own children are mechanisms through which neighbourhood social participation lowers the risk of depression among older adults in China.

“…In terms of mediating pathways, mediators, such as air pollution, social interactions, and physical activities, also mediate the association between neighborhood greenspaces and residents' well-being. Air pollution, such as nitrogen dioxide, fine particulate matter (such as PM 2.5 ), and ozone, has negative health effects, and many studies have demonstrated the negative association between surrounding greenspaces and air pollution ( 40 – 42 ). Greenspaces can help in mitigating urban microclimates and effectively reducing urban environmental pollution and filtering health-threatening air pollutants by sticking wind-blown particulates, such as PM 2.5 and PM 10 , to plant leaves and stems ( 43 – 45 ).…”

According to the United Nations, the proportion of the older population is increasing at a faster rate than all other age groups. Hence, the well-being of older adults is a mounting concern worldwide in the current century. Using a single greenery metric, previous studies linked greenness to residents' well-being. This study aims to extend this field by focusing on the mental and physical well-being of older adults by using remote sensing and streetscape metrics in evaluating neighborhood greenness. We selected 20 residential neighborhoods in Guangzhou City, China as the cross-sectional case study areas. We investigated neighborhood normalized difference vegetation index (NDVI) collected using remote sensing images, streetscape greenery, and PM2.5 via field surveys. We assessed the health condition of 972 senior residents selected by multi-stage stratified probability proportionate to population size sampling technique (PPS) using a questionnaire survey. We adopted the structural equation model (SEM) in analyzing the pathways that link neighborhood greenness and the mental and physical health of older adults. We found that neighborhood greenness has a positive association with the physical activity by older adults that is positively linked to their physical health. Moreover, neighborhood greenness is positively related to regular social interactions among older adults that is positively linked to their mental health. These findings are consistent with those of previous studies. However, we obtained new results that were unique to China. We found that neighborhood greenness has no significant direct relationship with the physical and mental health of older adults and that social interactions of low-income senior groups are more substantially related to neighborhood greenness than the other groups. Therefore, community planning should emphasize the development of neighborhood greenness, such as parks and street trees, to provide natural spaces for social interactions and places for physical activities among older residents.
