Do perceived neighbourhood cohesion and safety contribute to neighbourhood differences in health?

This paper reports on a survey (N=3344) and in-depth interviews (N=80) from four socio-economically contrasting postcode areas in Adelaide. Logistic regression was used to examine locational differences in self-rated health, controlling for demographic, socio-economic factors, health behaviours, individual social capital (social networks, support, reciprocity, trust) and perceived neighbourhood cohesion and safety. Statistically significant locational differences in health emerged. Perceived neighbourhood cohesion and safety accounted for this difference. Interviews explored perceptions of cohesion and safety and found that they were intricately related and varied between the areas. The implications of the findings for understanding locational differences in health are discussed.     

Perception of place and health: Differences between neighbourhoods in the Québec City region

This paper addresses two questions: (1) Can people's perceptions of problems and social cohesion in the neighbourhood be considered as contextual variables; and (2) are these perceptions related to people's health? Data come from a general health survey carried out in 2004 among 1634 individuals living in three localities of the region of Québec City, namely a downtown, a suburban and a rural area, which were further subdivided into 34 smaller spatial units, hereafter called neighbourhoods. The survey included questions on individuals’ perception of problems (social and environmental) and social cohesion (attraction to neighbourhood, neighbouring and psychological sense of community) in the neighbourhood, as well as questions on self-rated health, long-term disability and self-mastery. A first set of logistic multilevel models was performed to ascertain the existence of neighbourhood variations in the perception of problems and social cohesion, after accounting for individual attributes. A second set of multilevel models was carried out to examine the association between perceived problems and social cohesion in the neighbourhood and people's health. Results show that, after accounting for individual attributes, the perception of problems and social cohesion varies significantly by neighbourhood and/or localities and can be considered as contextual variables. Furthermore, these perceptions of place appear to be significant predictors of people's health.     

The importance of gender and conceptualization for understanding the association between collective social capital and health: a multilevel analysis from northern Sweden

Growing research on social capital and health has fuelled the debate on whether there is a place effect on health. A central question is whether health inequality between places is due to differences in the composition of people living in these places (compositional effect) or differences in the local social and physical environments (contextual effects). Despite extensive use of multilevel approaches that allows controlling for whether the effects of collective social capital are confounded by access to social capital at the individual level, the picture remains unclear. Recent studies indicate that contextual effects on health may vary for different population subgroups and measuring "average" contextual effects on health for a whole population might therefore be inappropriate. In this study from northern Sweden, we investigated the associations between collective social capital and self-rated health for men and women separately, to understand if health effects of collective social capital are gendered. Two measures of collective social capital were used: one conventional measure (aggregated measures of trust, participation and voting) and one specific place-related (neighbourhood) measure. The results show a positive association between collective social capital and self-rated health for women but not for men. Regardless of the measure used, women who live in very high social capital neighbourhoods are more likely to rate their health as good-fair, compared to women who live in very low social capital neighbourhoods. The health effects of collective social capital might thus be gendered in favour for women. However, a more equal involvement of men and women in the domestic sphere would potentially benefit men in this matter. When controlling for socioeconomic, sociodemographic and social capital attributes at the individual level, the relationship between women's health and collective social capital remained statistically significant when using the neighbourhood-related measure but not when using the conventional measure. Our results support the view that a neighbourhood-related measure provides a clearer picture of the health effects of collective social capital, at least for women.     

Neighbourhood life and social capital: the implications for health

Social capital has been linked to health outcomes, though there are some inconsistencies in the research and the link is dependent on the measures of social capital and health used. In this paper, we argue that social capital is multifaceted and its relationship with health is complex. We explore the relationship between a number of elements of neighbourhood life and neighbourhood-based social capital, and health, using both qualitative and quantitative methods. The paper reports on a study of the Western suburbs of Adelaide and the analysis of 2400 questionnaires and 40 in-depth interviews. A partial least-square path analysis was undertaken with the questionnaire data. It considered the impact of perceptions of the physical environment, neighbourhood connections, neighbourhood trust, reciprocity, perceived safety and local civic action, and a number of demographic variables, on physical and mental health as measured by the SF-12. Of the neighbourhood-related variables, only perceived neighbourhood safety was related to physical health, with neighbourhood safety and neighbourhood connections related to mental health. Of the demographic variables, higher-income level and educational achievement were related to better physical and mental health. In addition, physical health was lower and mental health higher within older age groups. The inter-relationships between the neighbourhood variables and demographic differences in experience of neighbourhood were also examined. The thematic analysis of the interviews linked a number of social aspects of neighbourhood, the physical neighbourhood environment, perceptions of safety, civic activities and availability of local services, to health outcomes. The paper concludes that there is a need for more complex measures of social capital and that socio-economic factors are of relatively greater importance in determining health.     

Multilevel analyses of neighbourhood socioeconomic context and health outcomes: a critical review

PURPOSE: Interest in the effects of neighbourhood or local area social characteristics on health has increased in recent years, but to date the existing evidence has not been systematically reviewed. Multilevel or contextual analyses of social factors and health represent a possible reconciliation between two divergent epidemiological paradigms-individual risk factor epidemiology and an ecological approach. DATA SOURCES: Keyword searching of Index Medicus (Medline) and additional references from retrieved articles. STUDY SELECTION: All original studies of the effect of local area social characteristics on individual health outcomes, adjusted for individual socioeconomic status, published in English before 1 June 1998 and focused on populations in developed countries. DATA SYNTHESIS: The methodological challenges posed by the design and interpretation of multilevel studies of local area effects are discussed and results summarised with reference to type of health outcome. All but two of the 25 reviewed studies reported a statistically significant association between at least one measure of social environment and a health outcome (contextual effect), after adjusting for individual level socioeconomic status (compositional effect). Contextual effects were generally modest and much smaller than compositional effects. CONCLUSIONS: The evidence for modest neighbourhood effects on health is fairly consistent despite heterogeneity of study designs, substitution of local area measures for neighbourhood measures and probable measurement error. By drawing public health attention to the health risks associated with the social structure and ecology of neighbourhoods, innovative approaches to community level interventions may ensue.     

Social capital, socio-economic status and psychological distress among Australian adults

High levels of social capital may be associated with positive mental health in adults. However, quantifying the various dimensions of social capital has presented a challenge due in part to the diverse definitions and measures used. Data from a representative, population-wide survey of Australian adults aged 16 years and older were used to investigate the links between dimensions of social capital and mental health morbidity. Social capital comprised three constructs and was measured at the individual level: feelings of trust and safety, community participation and neighbourhood connections and reciprocity. Mental health was measured by the 10-item Kessler (K10) instrument and assessed symptoms of psychological distress (i.e., depression and anxiety) over the previous month. Community participation showed a weak, and neighbourhood connections and reciprocity a moderate association with distress. Having higher levels of trust and feeling safe were consistently associated with low levels of psychological distress, after adjusting for socio-demographic characteristics and health conditions. The results clearly demonstrate that having trust in people, feeling safe in the community and having social reciprocity are associated with lower risk of mental health distress. The implications for conceptualising and measuring the individual and collective (contextual) dimensions of social capital are discussed. The findings also suggest the importance of examining the interrelationships between socio-economic status, social capital and mental health for community-dwelling adults.     

Neighbourhood deprivation and self-rated health: the role of perceptions of the neighbourhood and of housing problems

It has been known for a long time that people living in socially and economically deprived neighbourhoods generally experience poorer health. However, it is often not clear what processes underlie the relationship between neighbourhood deprivation and individual health. In this study we explore the association between neighbourhood socio-economic status and self-rated health using the Caerphilly Health and Social Needs Survey (n=10,892). We found that the association between neighbourhood deprivation and self-rated health was substantially reduced after adjusting for individual socio-economic status, but remained statistically significant. This suggests that the health effects of neighbourhood deprivation are partly contextual. We also found that the association between neighbourhood deprivation and self-rated health was further attenuated when controlling for perceptions of the neighbourhood and of housing problems, suggesting that these variables may play a role in mediating the health effects of neighbourhood deprivation. The implications of the results are that health policy should target 'places' as well as 'people'; and that policies aimed at improving the quality of housing, access to amenities, neighbourhood safety, and social cohesion may help to reduce health inequalities.     

Social capital and perceived health in Japan: An ecological and multilevel analysis

Numerous empirical studies, largely conducted in Western societies, have linked social capital to health outcomes. However, few studies thus far have been conducted in northeastern Asian countries, particularly Japan. Therefore, whether social capital is a determinant of health in Japanese society remains unclear. This study attempted to provide new evidence for the impact of social capital on health in Japan by analyzing original survey data with two different statistical models. In total, 1910 subjects were randomly selected from 210 enumeration districts (EDs) considered in the 2000 population census. In the present study, after excluding missing data on the outcome and predictor variables, we conducted an analysis of 1157 individuals nested within 206 EDs. Ecological and multilevel regression analyses were performed to examine the association between social capital and health, measured by the General Health (GH) perception item (a subcategory of Short Form 36 (SF-36)), and to estimate the impact of aggregated indicators of social capital on health. We developed an original Japanese version of three social capital items (perceived helpfulness, kindness, and greeting) based on previous studies and expert opinions and prepared a social cohesion index that integrated these three social capital items. The ecological model, after adjusting for sociodemographic factors, revealed that perceived helpfulness and greeting, along with the social cohesion index, were observed to have statistically significant associations with GH. The multilevel model, after adjusting for individual social capital perceptions, indicated that the two aggregated indicators of community social capital (kindness and greeting), along with the social cohesion index, showed a statistically significant association with GH. These results showed the existence of a contextual effect of social capital on health outcomes, although individual differences in social capital perceptions in Japan were considered.     

Social capital and young adolescents' perceived health in different sociocultural settings

We conducted a cross-national study to examine the association between neighbourhood socioeconomic deprivation, social capital and child health in two countries and multiple ethnic groups. For our analysis we used data from (1) the Project on Human Development in Chicago Neighborhoods (PHDCN), USA and (2) the Maastricht Quality of Life study (MQoL), the Netherlands. Both the PHDCN and the MQoL collected data on objective neighbourhood socioeconomic deprivation, subjective neighbourhood social capital (i.e. informal social control, ISC, social cohesion and trust, SC&T), and children's perceived health. For the present analyses, 11- and 12-year olds were selected. Multilevel analyses were conducted using both neighbourhood level and individual-level data. Lower socioeconomic deprivation scores and higher levels of ISC as well as SC&T were associated with higher levels of children's perceived health, in both Maastricht and the Chicago Hispanic subsample, but not in the Chicago non-Hispanic samples. The results suggest that associations between the wider social environment and health outcomes vary across different populations and cross-national contexts.     

Contextual social capital as a risk factor for poor self-rated health: a multilevel analysis

In this study, we critically examine whether contextual social capital (CSC) is associated with self-rated health, with an emphasis on the problem of confounding. We also examine different components of CSC and their association with self-rated health. Finally, we look at differences in susceptibility between different socio-demographic groups. We use the cross-sectional base line study of the Stockholm Public Health Cohort, conducted in 2002. A postal questionnaire was answered by 31,182 randomly selected citizens, 18-84 years old, in Stockholm County. We used four measures of social capital: horizontal (civic trust and participation), vertical (political trust and participation), cognitive (civic and political trust) and structural (civic and political participation). CSC was measured at parish level from aggregated individual data, and multilevel regression procedures were employed. We show a twofold greater risk of poor self-rated health in areas with very low CSC compared with areas with very high CSC. Adjustments for individual socio-demographic factors, contextual economic factors and individual social capital lowered the excess risk. Simultaneous adjustment for all three forms of confounding further weakened the association and rendered it insignificant. Cognitive and structural social capital show relatively similar associations with self-rated health, while horizontal CSC seems to be more strongly related to self-rated health than vertical CSC. In conclusion, whether there is none or a moderate association between CSC and self-rated health, depends on the extent to which individual social capital is seen as a mediator or confounder. The association with self-rated health is similar independent of the measure of CSC used. It is also similar in different socio-demographic groups.     

Neighbourhood environment and positive mental health in older people: the Hertfordshire Cohort Study

Little is known about the potential effects of neighbourhood environment on positive mental health in older people. We examined cross-sectional associations between the index of multiple deprivation score of the census area of residence, perceptions of neighbourhood cohesion and neighbourhood problems and mental wellbeing, as measured by the Warwick-Edinburgh Mental Wellbeing Scale, in 1157 men and women aged 69-78 years from Hertfordshire, UK. We found no association between area-level deprivation and mental wellbeing. People who felt a stronger sense of cohesion within their neighbourhood and reported fewer neighbourhood problems had higher levels of mental wellbeing, independently of social class, income, presence of limiting illness or disability, mobility problems, and perceived social support. Adjustment for emotional stability attenuated the associations between mental wellbeing and both of these measures of perceived neighbourhood environment, particularly in the case of neighbourhood problems. How older people feel about their neighbourhood may be important for positive mental health in later life.     

Individual and neighbourhood determinants of social participation and social capital: a multilevel analysis of the city of Malmö, Sweden

The aim of this study was to analyse the impact of neighbourhood on individual social capital (measured as social participation). The study population consisted of 14,390 individuals aged 45–73 that participated in the Malmö diet and cancer study in 1992–1994, residing in 90 neighbourhoods of Malmö, Sweden (population 250,000). A multilevel logistic regression model, with individuals at the first level and neighbourhoods at the second level, was performed. The study analysed the effect (intra-area correlation and cross-level modification) of the neighbourhood on individual social capital after adjustment for compositional factors (e.g. age, sex, educational level, occupational status, disability pension, living alone, sick leave, unemployment) and, finally, one contextual migration factor. The prevalence of low social participation varied from 23.0% to 39.7% in the first and third neighbourhood quartiles, respectively. Neighbourhood factors accounted for 6.3% of the total variance in social participation, and this effect was reduced but not eliminated when adjusting for all studied variables (−73%), especially the occupational composition of the neighbourhoods (−58%). The contextual migration variable further reduced the variance in social participation at the neighbourhood level to some extent. Our study supports Putnam's notion that social capital, which is suggested to be an important factor for population health and possibly for health equity, is an aspect that is partly contextual in its nature.     

Individual and neighbourhood determinants of social participation and social capital: a multilevel analysis of the city of Malmö, Sweden

Social capital and sense of insecurity in the neighbourhood: a population-based multilevel analysis in Malmö, Sweden

The aim of this study was to investigate the influence of social capital on self-reported sense of insecurity in the neighbourhood. The public health survey in Malm?, Sweden in 1994 was a cross-sectional study. A total of 5600 individuals aged 20-80 years were asked to answer a postal questionnaire. The participation rate was 71%. A multilevel logistic regression model, with individuals at the first level and neighbourhoods at the second, was performed. We analysed the effect (intra-area correlation, cross-level modification and odds ratios) of individual (social participation) and neighbourhood social capital (electoral participation in the 1994 municipal election) on sense of insecurity after adjustment for compositional factors. Neighbourhood factors accounted for 7.2% of the total variance in individual insecurity. This effect was marginally reduced when the individual factors were included in the model. In contrast, it was reduced by 70% by the introduction of the contextual variable. This study suggests that social capital, measured as electoral participation, may partly explain the individual's sense of insecurity in the neighbourhood.     

Associations between physical activity and the neighbourhood social environment: baseline results from the HABITAT multilevel study

Limitations have arisen when measuring associations between the neighbourhood social environment and physical activity, including same-source bias, and the reliability of aggregated neighbourhood-level social environment measures. This study examines cross-sectional associations between the neighbourhood social environment (perceptions of incivilities, crime, and social cohesion) and self-reported physical activity, while accounting for same-source bias and reliability of neighbourhood-level exposure measures, using data from a large population-based clustered sample. This investigation included 11,035 residents aged 40–65 years from 200 neighbourhoods in Brisbane, Australia, in 2007. Respondents self-reported their physical activity and perceptions of the social environment (neighbourhood incivilities, crime and safety, and social cohesion). Models were adjusted for individual-level education, occupation, and household income, and neighbourhood disadvantage. Exposure measures were generated via split clusters and an empirical Bayes estimation procedure. Data were analysed in 2016 using multilevel multinomial logistic regression. Residents of neighbourhoods with the highest incivilities and crime, and lowest social cohesion were reference categories. Individuals were more likely to be in the higher physical activity categories if they were in neighbourhoods with the lowest incivilities and the lowest crime. No associations were found between social cohesion and physical activity. This study provides a basis from which to gain a clearer understanding of the relationship between the neighbourhood social environment and individual physical activity. Further work is required to explore the pathways between perceptions of the neighbourhood social environment and physical activity.     

Social Cohesion and Mortality: A Survival Analysis of Older Adults in Japan

Objectives. We examined the association between social cohesion and mortality in a sample of older adults in Japan.Methods. Data were derived from a cohort study of elderly individuals (65–84 years) in Shizuoka Prefecture; 14 001 participants were enrolled at baseline (1999) and followed up in 2002, 2006, and 2009. Among the 11 092 participants for whom we had complete data, 1427 had died during follow-up. We examined the association between social cohesion (assessed at both the community and individual levels) and subsequent mortality after control for baseline and time-varying covariates. We used clustered proportional hazard regression models to estimate hazard ratios (HRs) and confidence intervals (CIs).Results. After control for individual characteristics, individual perceptions of community cohesion were associated with a reduced risk of all-cause mortality (HR = 0.78; 95% CI = 0.73, 0.84) as well as mortality from cardiovascular disease (HR = 0.75; 95% CI = 0.67, 0.84), pulmonary disease (HR = 0.66; 95% CI = 0.58, 0.75), and all other causes (HR = 0.76; 95% CI = 0.66, 0.89). However, no statistically significant relationship was found between community cohesion and mortality risk.Conclusions. Among the elderly in Japan, more positive individual perceptions of community cohesion are associated with reduced risks of all-cause and cause-specific mortality.A growing body of research has focused on social cohesion as a determinant of population health.1 Higher levels of community social cohesion—characterized by closely knit social relationships among residents with strong mutual trust and reciprocity—have been linked to better health outcomes such as lower mortality rates and higher self-rated health.1–10However, prospective studies of social cohesion and health remain sparse, and there is continuing debate about whether such associations are driven by individual residents’ psychological perceptions about their communities or by the characteristics of the communities per se.11 In other words, cohesive communities may be healthier either because residents are psychologically healthier and express trust toward their neighbors (a compositional effect) or because the community social environment promotes health via group-level processes such as the ability to undertake collective action, for example mobilizing local volunteers to participate in health promotion activities (a contextual effect).Multilevel analytical techniques are required to tease out the compositional effects of community cohesion from its contextual effects. To date, there has been stronger empirical support for an association between individual-level perceptions of social cohesion and health outcomes and less evidence for a community-level contextual effect.11Japanese society has historically been characterized by high levels of social cohesion. The reasons for this include the roughly 2 centuries of isolationism (from 1633 until 1853) enforced by the Tokugawa shogunate (a feudal Japanese military government), as well as the comparative ethnic homogeneity of the Japanese population.12 Recent multilevel studies conducted in Japan suggest an association between community social cohesion and improved health outcomes, including higher self-rated health,13 a lower risk of depression,14 and a lower incidence of functional disabilities.15 Two of these studies were conducted among older Japanese people.13,15 However, according to a systematic review of multilevel studies of income inequality, prospective studies remain sparse, and more evidence is needed to establish the robustness of the association between income inequality and population health.11With few exceptions, the empirical evidence linking community social cohesion to health has been based on cross-sectional study designs, and there is a dearth of longitudinal evidence. We examined the long-term associations between social cohesion and mortality in a sample of older Japanese adults.     

Does social trust at school affect students’ smoking and drinking behavior in Japan?

This study examined the individual and contextual effects of cognitive social capital at school on cigarette smoking and alcohol drinking in Japanese high school students. Self-administered questionnaires were distributed to 3248 students in grades 10-12 (aged 15-18 years) at 29 public high schools across Okinawa, Japan in 2008. The individual-level cognitive social capital studied was generalized trust. Using multi-level logistic regression models, the effects of individual- and contextual-level cognitive social capital on smoking and drinking were analyzed. Contextual-level cognitive social capital was measured on the basis of aggregated individual responses to the trust question at school level. After adjustment for the covariates, individual-level trust was negatively associated with smoking and drinking among boys and girls. Similarly, after adjustment for the covariates, school-level trust showed an inverse association with smoking for girls. A similar but not statistically significant association was observed for boys. On the other hand, school-level trust was not associated with drinking among boys or girls. After adjustment for individual-level trust and the covariates, these findings were in the same direction, but the school-level trust for girls no longer had a significant contextual effect on smoking. The findings suggest evidence of the individual effect of cognitive social capital on adolescents' smoking and drinking, and that the contextual effect of social capital on smoking was inconclusive. In addition, no association of contextual-level social capital with drinking was observed.     

Individual social capital, neighbourhood deprivation, and self-rated health in England

Individual social capital is increasingly considered to be an important determinant of an individual's health. This study examines the extent to which individual social capital is associated with self-rated health and the extent to which individual social capital mediates t.he relationship between neighbourhood deprivation and self-rated health in an English sample. Individual social capital was conceptualized and operationalized in both the social cohesion- and network resource tradition, using measures of generalized trust, social participation and social network resources. Network resources were measured with the position generator. Multilevel analyses were applied to wave 2 and 3 of the Taking Part Surveys of England, which consist of face-to-face interviews among the adult population in England (N(i) = 25,366 respondents, N(j) = 12,388 neighbourhoods). The results indicate that generalized trust, participation with friends and relatives and having network members from the salariat class are positively associated with self-rated health. Having network members from the working class is, however, negatively related to self-rated health. Moreover, these social capital elements are partly mediating the negative relationship between neighbourhood deprivation and self-rated health.     

Community resilience and health: the role of bonding, bridging, and linking aspects of social capital

The current study draws on data from the 2007 and 2009 Citizenship Survey collected in England (n=17,572) to explore the role of social capital in building community resilience and health, using the bonding, bridging, and linking social capital framework of Szreter and Woolcock (2004). The results show that the indicators of the different types of social capital are only weakly interrelated, suggesting that they capture different aspects of the social environment. In line with the expectations, most indicators of bonding, bridging, and linking social capital were significantly associated with neighbourhood deprivation and self-reported health. In particular bonding and bridging social cohesion, civic participation, heterogeneous socio-economic relationships, and political efficacy and trust appeared important for community health after controlling for neighbourhood deprivation. However, no support was found for the hypothesis that the different aspects help buffer against the detrimental influences of neighbourhood deprivation.     

Neighbourhood community life and health: A systematic review of reviews

Neighbourhood community life has been widely recognized as an important determinant of population health. This systematic review of reviews provides an overview of the evidence for the ecological correlation between neighbourhood community life and population health. Nine databases were searched from 2008 to 2018 in order to identify systematic reviews of studies examining the association between neighbourhood community life and population health in urban neighbourhoods within the Organisation for Economic Co-operation and Development countries. Two reviewers completed selection and data extraction, then assessed the methodological quality of reviews using the Measurement Tool to Assess Systematic Reviews. We identified three high quality reviews and five of moderate quality. The reviews vary in quality of methodology, concepts, and measures. Most of the reviews examined the influence of social cohesion, social capital, and social interactions on health. Reviews found evidence supporting a consistently favourable correlation between social cohesion and physical activity, as well as a favourable trend in the relationship between social cohesion and healthy weight. They also found evidence of a favourable trend in the correlation between social capital and healthy weight. Reviews identified studies supporting a consistently favourable correlation between social interaction and depression. We identify evidence of a positive association between neighbourhood community life and several population health outcomes. Future research should define and conceptualize neighbourhood community life factors and health indicators to improve the comparison between studies and the process of evidence synthesis. This will also enable policy makers to take appropriate decisions.
