Does low workplace social capital have detrimental effect on workers' health?

While the majority of studies of social capital and health have focused on conceptualizing social capital at the geographic level, evidence remains sparse on workplace social capital. We examined the association between workplace social capital and health status among Japanese private sector employees in a cross-sectional study. By employing a two-stage stratified random sampling procedure, 1147 employees were identified from 46 companies in Okayama in 2007. Workplace social capital was measured based on two components; trust and reciprocity. Company-level social capital was based on aggregating employee responses and calculating the proportion of workers reporting mistrust and lack of reciprocity. Multilevel logistic regression analysis was conducted using Markov Chain Monte Carlo methods to explore whether individual- and company-level mistrust and lack of reciprocity were associated with poor self-rated health. Odds ratios (ORs) and 95% credible intervals (CIs) for poor health were obtained for each variable. Workers reporting individual-level mistrust and lack of reciprocity had approximately double the odds of poor health even after controlling for sex, age, occupation, educational attainment, smoking, alcohol use, physical activity, body mass index, and chronic diseases. While we found some suggestion of a contextual association between company-level mistrust and poor health, no association was found between company-level lack of reciprocity and health. Despite the thorough examination of cross-level interaction terms between company-level social capital and individual characteristics, no clear patterns were observed. Individual perceptions of mistrust and lack of reciprocity at work have adverse effects on self-rated health among Japanese workers. Although the present study possibly suggests the contextual effect of workplace mistrust on workers' health, the contextual effect of workplace lack of reciprocity was not supported.     

Social capital and health and well-being in East Asia: a population-based study

How individual-level social capital relates to adult health and well-being was examined using data from a cross-sectional interview survey in East Asia (Japan, South Korea, Singapore, five areas in Mainland China, and Taiwan) in 2002-2004. The number of self-reported somatic symptoms, subjective health satisfaction, life satisfaction and social capital indicators, as well as socio-economic status (SES), were analyzed by a logistic regression model. Adjusting for SES, social capital measured by belonging to organizations and weakness in "norms of reciprocity" were related to a greater number of self-reported somatic symptoms (p<0.001 for both). Lack of trust in organizations (p<0.001) and of a person to consult (p=0.012) were related to poor health satisfaction. Lower "interpersonal trust" (p=0.016), weakness in "norms of reciprocity" (p<0.001) and lack of trust in organizations (p<0.001) were related to poor life satisfaction. Gender inequality was observed across countries, but the relationships varied according to the health indicator. Specifically, self-reported somatic symptoms were more numerous and health satisfaction was worse in women (p<0.001), but life satisfaction was worse in men (p=0.017). The analyses provide evidence that dimensions of social capital are positively associated with self-reported somatic symptoms and overall well-being in East Asian countries.     

A multilevel analysis of social capital and self-rated health: Evidence from China

We investigate relationship between social capital and self-rated health (SRH) in urban and rural China. Using a nationally representative data collected in 2005, we performed multilevel analyses. The social capital indicators include bonding trust, bridging trust, social participation and Chinese Communist Party membership. Results showed that only trust was beneficial for SRH in China. Bonding trust mainly promoted SRH at individual level and bridging trust mainly at county level. Moreover, the individual-level bridging trust was only positively associated with SRH of urban residents, which mirrored the urban–rural dual structure in China. We also found a cross-level interaction effect of bonding trust in urban area. In a county with high level of bonding trust, high-bonding-trust individuals obtained more health benefit than others; in a county with low level of bonding trust, the situation was the opposite.     

Social capital and health. A study of adult twins in the U.S

BACKGROUND: A growing number of studies have suggested a link between social capital and health. However, the association may reflect confounding by factors, such as personality or early childhood environment, that are unmeasured prior common causes of both social capital and health outcomes. The purpose of this study was to investigate the impact of social capital on physical and mental health among adult twins in the U.S. METHODS: A cross-sectional national survey of twins within the National Survey of Midlife Development in the U.S. (MIDUS), 1995--1996 was analyzed in 2007. The study population included 944 twin pairs (37.2% monozygotic [MZ] and 62.8% dizygotic [DZ]). Data were obtained on individual-level social capital variables (social trust, sense of belonging, volunteer activity, and community participation); health outcomes (perceived physical and mental health, depressive symptoms and major depression); and individual covariates (age, gender, race, education, working status, and marital status). A fixed-effects model was used to examine health status among twin pairs who were discordant on levels of social capital. RESULTS: In the individual data analysis, social trust, sense of belonging, and community participation were each significantly associated with health outcomes. In the fixed-effects model, physical health remained significantly positively associated with social trust among MZ and DZ twins. However, major depression was not associated with social capital. CONCLUSIONS: The present study is the first to find the independent positive effect of social trust on self-rated physical health using fixed-effects models of twin data. The results suggest that the association between social capital and physical health status is not explained by unobserved confounds, such as personality or early childhood environment.     

Does social capital enhance health and well-being? Evidence from rural China

Despite increasing acknowledgement that social capital is an important determinant of health and overall well-being, empirical evidence regarding the direction and strength of these linkages in the developing world is limited and inconclusive. This paper empirically examines relationships between social capital and health and well-being-as well as the suitability of commonly used social capital measures-in rural China, where rapid economic growth coexists with gradual and fundamental social changes. To measure social capital, we adopt a structural/cognitive distinction, whereby structural social capital is measured by organizational membership and cognitive social capital is measured by a composite index of trust, reciprocity, and mutual help. Our outcome measures included self-reported general health, psychological health, and subjective well-being. We adopt multi-level estimation methods to account for our conceptualization of social capital as both an individual- and contextual-level resource. Results indicate that cognitive social capital (i.e., trust) is positively associated with all three outcome measures at the individual level and psychological health/subjective well-being at the village level as well. We further find that trust affects health and well-being through pathways of social network and support. In contrast, there is little statistical association or consistent pattern between structural social capital (organizational membership) and the outcome variables. Furthermore, although organizational membership is highly correlated with collective action, neither is associated with health or well-being. Our results suggest that policies aimed at producing an environment that enhances social networks and facilitates the exchange of social support hold promise for improving the health and well-being of the rural Chinese population. In addition, China may not have fully taken advantage of the potential contribution of structural social capital in advancing health and well-being. A redirection of collective action from economic to social activities may be worth considering.

Social capital and its relationship with measures of health status: evidence from the Health Survey for England 2003

Social capital is a concept that attempts to describe the quantity and quality of social interactions in a community. This study explores the relationship between individual measures of social capital and alternative measures of health status within the context of a large national survey of population health. Using data for 13 753 adult participants in the 2003 Health Survey for England, linear regression with weighted least-squares estimation and Tobit regression with upper censoring were used to model the relationship between individual measures of social capital and EQ-5D utility scores. In addition, logistic regression was used to model the relationship between individual measures of social capital and a dichotomous self-reported health status variable. The study demonstrated that low stocks of social capital across the domains of trust and reciprocity, perceived social support and civic participation are significantly associated with poor measures of health status. The implications for health economists and, potentially, for policymakers are discussed.     

Social capital and self‐rated health: A cross‐sectional study of the general social survey data comparing rural and urban adults in Ontario

The concept of social capital shows great promise for its potential to influence individual and population health. Yet challenges persist in defining and measuring social capital, and little is known about the mechanisms that link social capital and health. This paper reports on the quantitative phase of a sequential explanatory mixed methods study using data from Canada's 2013 General Social Survey (data collected 2013–14). An exploratory factor analysis revealed six underlying dimensions of social capital for 7,187 adults living in Ontario, Canada. These factors included trust in people, neighbourhood social capital, trust in institutions, sense of belonging, civic engagement, and social network size. A logistic regression indicated that having high Trust in People and Trust in Institutions were associated with better mental health while high Trust in Institutions, Sense of Belonging, and Civic Engagement were associated with better physical health. When comparing rural and urban residents, there were no differences in their self‐reported health, nor did social capital influence their health any differently, despite rural residents having higher social capital scores. The study findings are important for understanding the nature of social capital and how it influences health, and provide direction for targeted health promotion strategies.     

Health differences between European countries

This paper examines self-reported health among individuals in 21 European countries. The purpose is to analyze how both individual- and country-level characteristics influence health. The study is based on data from the European Social Survey (ESS) conducted in 2003 and employs hierarchical modelling (N=38,472). We present three main findings: (1) individual-level characteristics, such as age, education, economic satisfaction, social network, unemployment, and occupational status are related to the health of individuals, both for women and men; (2) we tested how societal features, such as public expenditure on health, socioeconomic development, lifestyle, and social capital (social trust) were related to subjective health. Among the country-level characteristics, socioeconomic development, measured as GDP per capita (logarithm), is the indicator that is most strongly associated with better health, after controlling for individual-level characteristics; (3) the eastern European countries stand out as the countries where individuals report the poorest health. In our models, the individual-level variables explain 60% of the variance between countries, whereas 40% is explained by the macro-level variables.     

Social capital and health in Australia: An overview from the household,income and labour dynamics in Australia survey

Social capital is associated with better health, but components of social capital and their associations with different types of health are rarely explored together. The aim of this study was to use nationally representative data to develop population norms of community participation and explore the relationships between structural and cognitive components of social capital with three forms of health – general health, mental health and physical functioning. Data were taken from Wave 6 (2006) of the Household, Income and Labour Dynamics in Australia Survey. Using individual-level data, the structural component of social capital (community participation) was measured using a twelve-item short-form of the Australian Community Participation Questionnaire, and the cognitive component (social cohesion) by sense of belonging, tangible support, trust and reciprocity. Three subscales of the SF-36 provided measures of health. Multiple hierarchical regression modelling was used to investigate multivariate relationships among these factors. Higher levels of participation were related to higher levels of social cohesion and to all three forms of (better) health, particularly strongly to mental health. These findings could not be accounted for by sex, age, Indigenous status, education, responsibility for dependents, paid work, living alone or poverty. Controlling for these and physical health, structural and cognitive components of social capital were each related to mental health, with support for a possible mediated relationship between the structural component and mental health. Social capital was related to three forms of health, especially to mental health. Notable gender differences in this relationship were evident, with women reporting greater community participation and social cohesion than men, yet worse mental health. Understanding the mechanisms underlying this apparent anomaly needs further exploration. Because community participation is amenable to intervention, subject to causal testing, our findings may assist in the development of programs which are effective in promoting social cohesion and, thereby, mental health.     

A multilevel analysis of social capital and self-rated health: Evidence from the British Household Panel Survey

Social capital is often described as a collective benefit engendered by generalised trust, civic participation, and mutual reciprocity. This feature of communities has been shown to associate with an assortment of health outcomes at several levels of analysis. The current study assesses the evidence for an association between area-level social capital and individual-level subjective health. Respondents participating in waves 8 (1998) and 9 (1999) of the British Household Panel Survey were identified and followed-up 5 years later in wave 13 (2003). Area social capital was measured by two aggregated survey items: social trust and civic participation. Multilevel logistic regression models were fitted to examine the association between area social capital indicators and individual poor self-rated health. Evidence for a protective association with current self-rated health was found for area social trust after controlling for individual characteristics, baseline self-rated health and individual social trust. There was no evidence for an association between area civic participation and self-rated health after adjustment. The findings of this study expand the literature on social capital and health through the use of longitudinal data and multilevel modelling techniques.     

Contextual effect of different components of social capital on health in a suburban city of the greater Tokyo area: A multilevel analysis

Social capital (SC) can be broken down into a number of aspects and dimensions, but few studies have differentiated between the effects of different components of SC on health. This study examined the relationship between contextual SC and health (self-rated health, and co-occurrence of lifestyle risk factors such as smoking, drinking, overweight/underweight and physical inactivity) among the general population in a Japanese suburban area. The specific research question was to explore which components of contextual SC had what effects on health. In 2009, we randomly selected 4123 residents, aged 20 years and over, from 72 districts in the city of Kashiwa, Chiba prefecture (a typical suburban city of Tokyo) to participate in a cross-sectional survey using mailed questionnaires. We used four indicators of SC: cognitive/horizontal (trust in neighbors), cognitive/vertical (institutional trust in the national social security system), structural/horizontal (participation in groups with egalitarian relationships) and structural/vertical (participation in groups with hierarchical relationships). District-level SC was calculated by aggregating the individual responses of each SC indicator within each district. The response rate was 42.1% (1716 questionnaires), 43.7% of the respondents were male, and the mean age was 54.8 ± 16.4 (ranging from 20 to 97). A multilevel analysis showed that higher district-level institutional mistrust was associated with self-rated poor health, but higher district-level mistrust in neighbors was inversely associated with it, after adjusting for individual-level covariates. There was no contextual effect of any SC components on co-occurrence of risk factors. Our findings showed that institutional trust has a beneficial effect on self-rated health, but trust among neighbors might negatively affect the health of the residents in a Japanese suburban city. These unique findings could suggest the advantage of breaking down SC to examine more specific relationships between SC and health, and the importance of accumulating the evidence in specific cohorts to develop customized health promotion strategies.     

Social capital and health among the aged: comparisons between the United States and Germany

Through a cross-national investigation of the United States and Germany, this study examines how individual level social capital relates to the health of the elderly. Data from two national telephone surveys conducted in Germany (N=682) and the United States (N=608) with probability samples of non-institutionalized persons aged 60 and older was used. Indicators of social capital including both norms (reciprocity and civic trust) and behaviors (participation) were tested with three self-reported health indicators-overall health, depression (CES-D) and functional limitations. Housing variables and social support were controlled for in the study. Lack of reciprocity was associated with poorer self-rated health in both countries. Civic mistrust was associated with poorer self-rated health in both countries as well as with depression and functional limitations in America. Lack of participation was, in Germany, associated with poorer self-rated health and depression. The cross-national results indicate that individual-level analysis of social capital along with marco-level determinants are important for understanding the health of the elderly.     

The impact of changes in different aspects of social capital and material conditions on self-rated health over time: A longitudinal cohort study

Individual aspects of social capital have been shown to have significant associations with health outcomes. However, research has seldom tested different elements of social capital simultaneously, whilst also adjusting for other well-known health determinants over time. This longitudinal individual-level study investigates how temporal changes in social capital, together with changes in material conditions and other health determinants affect associations with self-rated health over a six year period. We use data from the British Household Panel Survey, a randomly selected cohort which is considered representative of the United Kingdom's population, with the same individuals (N = 9303) providing responses to identical questions in 1999 and 2005. Four measures of social capital were used: interpersonal trust, social participation, civic participation and informal social networks. Material conditions were measured by total income (both individual and weighted household income), net of taxation. Other health determinants included age, gender, smoking, marital status and social class. After the baseline sample was stratified by health status, associations were examined between changes in health status and changes in all other considered variables. Simultaneous adjustment revealed that inability to trust demonstrated a significant association with deteriorating self-rated health, whereas increased levels of social participation were significantly associated with improved health status over time. Low levels of household and individual income also demonstrated significant associations with deteriorating self-rated health. In conclusion, it seems that interpersonal trust and social participation, considered valid indicators of social capital, appear to be independent predictors of self-rated health, even after adjusting for other well-known health determinants. Understandably, how trust and social participation influence health outcomes may help resolve the debate surrounding the role of social capital within the field of public health.     

Social capital, the miniaturisation of community and self-reported global and psychological health

Social capital is often operationalised as social participation in the activities of the formal and informal networks of civil society and/or as generalised trust. Social participation and trust are two aspects of social capital that mutually affect each other, according to the literature. In recent years there has been an increased attention to the fact that generalised trust decreases for every new birth cohort that reaches adulthood in the USA, while social participation may take new forms such as ideologically much narrower single-issue movements that do not enhance trust. The phenomenon has been called "the miniaturisation of community". The effects of similar patterns in Sweden on self-reported health and self-reported psychological health are analysed. The odds ratios of bad self-reported global health are highest in the low-social capital category (low-social participation/low trust), but the miniaturisation of community and low-social participation/high-trust categories also have significantly higher odds ratios than the high-social capital category (high-social participation/high trust). The odds ratios of bad self-reported psychological health are significantly higher in both the low-social capital category and the miniaturisation of community category compared to the high-social capital category, while the low-social participation/high-trust category does not differ from the high-social capital reference group.     

Social capital and self-rated health--a study of temporal (causal) relationships

Despite the vast amount of research over the past fifteen years, there is still lively debate surrounding the role of social capital on individual health outcomes. This seems to stem from a lack of consistency regarding the definition, measurement and plausible theories linking this contextual phenomenon to health. We have further identified a knowledge gap within this field - a distinct lack of research investigating temporal relationships between social capital and health outcomes. To remedy this shortfall, we use four waves of the British Household Panel Survey to follow the same individuals (N = 8114) between years 2000 and 2007. We investigate temporal relationships and association between our outcome variable self-rated health (SRH) and time-lagged explanatory variables, including three individual-level social capital proxies and other well-known health determinants. Our results suggest that levels of the social capital proxy 'generalised trust' at time point (t - 1) are positively associated with SRH at subsequent time point (t), even after taking into consideration levels of other well-known health determinants (such as smoking status) at time point (t - 1). That we investigate temporal relationships at four separate occasions over the seven-year period lends considerable weight to our results and the argument that generalised trust is an independent predictor of individual health. However, lack of consensus across a variety of disciplines as to what generalised trust is believed to measure creates ambiguity when attempting to identify possible pathways from higher trust to better health.     

Opening the black box of the relationship between neighborhood socioeconomic status and mental health: Neighborhood social-interactive characteristics as contextual mechanisms

Previous studies have linked low neighborhood socioeconomic status (NSES) to mental health problems. However, few studies have investigated the mechanisms underlying this association and most focused on the association with negative indicators of mental health, such as symptoms of depression or anxiety. This paper investigated whether neighborhood social characteristics (social interaction, trust, safety, organization participation, and attachment) mediate the association between NSES and mental health. We combined Danish register data with survey data from the North Denmark Region Health Survey 2017. Mental health was assessed with the Rand 12-item Short-form Survey (SF-12). The sample consisted of 14,969 individuals nested in 1047 neighborhoods created with an automated redistricting algorithm. We fitted multilevel structural equation mediation models and used a Monte Carlo simulation method to estimate confidence intervals for the indirect effects. NSES was positively associated with mental health. Neighborhood trust significantly mediated this relationship, accounting for 34% of the association after controlling for other mediators. These results indicate that higher levels of mental health in more affluent neighborhoods are partially explained by higher levels of trust. Improving neighborhood trust could mitigate sociogeographic inequalities in mental health.     

How much does social capital add to individual health? A survey study of Russians

Some Russians are healthier than others. To what extent does their health vary with involvement or exclusion from social capital networks? The first section reviews alternative theories: human capital as the primary determinant; social capital, whether generic, situation-specific or simply a new label for old measures of social integration; or a composite theory--both human and social capital are major determinants of health. The evidence to test hypotheses consists of individual-level data about self-assessed physical and emotional health from the special-purpose social capital questionnaire used in the 1998 New Russia Barometer survey, a nationwide representative sample of the adult Russian population. Multiple regression analysis shows that on their own human capital and social capital each account for a notable amount of variance in health. When both forms of capital are combined in a composite model, each retains major influence, demonstrating that social capital does make an independent contribution to health. Significant social capital influences include involvement or exclusion from formal and informal networks; friends to rely on when ill; control over one's own life; and trust. Significant human capital influences besides age include subjective social status, gender and income. Regression-based estimates of impact show that social capital increases physical and emotional health more than human capital; together they can easily raise an individual's self-reported health from just below average on a five-point scale to approaching good health.     

Social capital and self-rated health in Colombia: the good, the bad and the ugly

Although there is increasing evidence supporting the associations between social capital and health, less is known of potential effects in Latin American countries. Our objective was to examine associations of different components of social capital with self-rated health in Colombia. The study had a cross-sectional design, using data of a survey applied to a nationally representative sample of 3025 respondents, conducted in 2004-2005. Stratified random sampling was performed, based on town size, urban/rural origin, age, and sex. Examined indicators of social capital were interpersonal trust, reciprocity, associational membership, non-electoral political participation, civic activities and volunteering. Principal components analysis including different indicators of social capital distinguished three components: structural-formal (associational membership and non-electoral political participation), structural-informal (civic activities and volunteering) and cognitive (interpersonal trust and reciprocity). Multilevel analyses showed no significant variations of self-rated health at the regional level. After adjusting for sociodemographic covariates, interpersonal trust was statistically significantly associated with lower odds of poor/fair health, as well as the cognitive social capital component. Members of farmers/agricultural or gender-related groups had higher odds of poor/fair health, respectively. Excluding these groups, however, associational membership was associated with lower odds of poor/fair health. Likewise, in Colombians with educational attainment higher than high school, reciprocity was associated with lower odds of fair/poor health. Nevertheless, among rural respondents non-electoral political participation was associated with worse health. In conclusion, cognitive social capital and associational membership were related to better health, and could represent important notions for health promotion. Human rights violations related to political violence and gender based discrimination may explain adverse associations with health.     

The effect of social capital on health: the case of two language groups in Finland

The aim of this study was to examine the association between individual-level social capital and two aspects of self-reported health-self-rated health and psychological health -- in Finland. Data were taken from a nationwide survey conducted in year 2000/2001. Two language groups, the Swedish-speakers and the Finnish-speakers in Finland were used as examples to illustrate ethnic differences in social capital. Moreover, social capital was used to explore the reasons behind health inequalities between the language groups. The results of the study demonstrated a positive association between individual-level cognitive social capital and the health outcomes. We further found that Swedish-speakers possess more structural and cognitive social capital compared to Finnish-speakers. Social capital explains to some extent health differences between the language groups. The results indicate the importance of considering ethnic differences in social determinants of health.
