Does social capital determine health? Evidence from eight transition countries

There is growing interest in the role of social relationships in explaining patterns of health. We contribute to this debate by investigating the impact of social capital on self‐reported health for eight countries from the Commonwealth of Independent States. We rely on three indicators of social capital at the individual level (trust, participation in local organisations, social isolation) and employ alternative procedures to estimate consistently the impact of social capital on health. The three social capital indicators are choice variables and are hence, by definition, endogenously determined. We attempt to circumvent the endogeneity problems by using instrumental variable estimates. Our results show that the individual degree of trust is positively and significantly correlated with health, this being true with least squares estimators as well as when relying on instrumental variable estimators with (and without) community fixed effects. Similarly, social isolation is negatively and significantly associated with health, irrespective of the procedure of estimation. On the other hand, the effect of being a member of a Putnamesque organisation is more ambiguous and usually not significantly related to health. Copyright © 2009 John Wiley & Sons, Ltd.     

Does health insurance coverage lead to better health and educational outcomes? Evidence from rural China

Using the 2006 China Agricultural Census (CAC), we examine whether the introduction of the New Cooperative Medical System (NCMS) has affected child mortality, maternal mortality, and school enrollment of 6-16year olds. Our data cover 5.9 million people living in eight low-income rural counties, of which four adopted the NCMS by 2006 and four did not adopt it until 2007. Raw data suggest that enrolling in the NCMS is associated with better school enrollment and lower mortality of young children and pregnant women. However, using a difference-in-difference propensity score method, we find that most of the differences are driven by endogenous introduction and take-up of the NCMS, and our method overcomes classical propensity score matching's failure to address selection bias. While the NCMS does not affect child morality and maternal mortality, it does help improve the school enrollment of six-year-olds.     

Does smoking affect schooling? Evidence from teenagers in rural China

Youth smoking can biologically reduce learning productivity. It can also reduce youths' expected returns to education and lower their motivation to go to school, where smoking is forbidden. Using rich household survey data from rural China, this study investigates the effect of youth smoking on educational outcomes. Youth smoking is clearly an endogenous variable; to obtain consistent estimates of its impact, we use counts of registered alcohol vendors and a food price index as instrumental variables. Since the variable that measures smoking behavior is censored for non-smoking adolescents, we implement a two-step estimation strategy to account for the censored nature of this endogenous regressor. The estimates indicate that smoking one cigarette per day during adolescence can lower students' scores on mathematics tests by about 0.08 standard deviations. However, we find no significant effect of youth smoking on either Chinese test scores or total years of schooling.     

Social relations or social capital? Individual and community health effects of bonding social capital

Social capital has become one of the most popular topics in public health research in recent years. However, even after a decade of conceptual and empirical work on this subject, there is still considerable disagreement about whether bonding social capital is a collective resource that benefits communities or societies, or whether its health benefits are associated with people, their personal networks and support. Using data from the 2000 and 2002 Health Survey for England this study found that, in line with earlier research, personal levels of social support contribute to a better self-reported health status. The study also suggests that social capital is additionally important for people's health. In both datasets the aggregate social trust variable was significantly related to self-rated health before and after controlling for differences in socio-demographics and/or individual levels of social support. The results were corroborated in the second dataset with an alternative indicator of social capital. These results show that bonding social capital collectively contributes to people's self-rated health over and above the beneficial effects of personal social networks and support.

Do health behaviors mediate the association between social capital and health?

INTRODUCTION: There is increasing evidence that social capital is important for people's health. However, there is still considerable disagreement about the specific pathways that links social capital to health. This study investigates the hypothesis that the association between social capital and health is mediated by people's health behaviors. METHOD: Data from the 2002 Health Survey for England (n = 7394) were used and analyzed from a multilevel perspective. The association between social capital and self-rated health were examined before and after controlling for smoking, alcohol intake, and fruit/vegetable consumption. RESULTS: Social capital was found to be associated with self-rated health, as well as with the different health behaviors. In addition, the health behaviors were significantly related to self-rated health. However, controlling for smoking, alcohol intake, and fruit/vegetable consumption did not substantially affect the association between social capital and self-rated health. CONCLUSIONS: The results demonstrate that social capital and support are important determinants of self-rated health and health behaviors. But only limited support was found for the hypothesis that health behaviors mediate the association between social capital and health.     

Are rural health professionals also social entrepreneurs?

Social entrepreneurs formally or informally generate community associations and networking that produces social outcomes. Social entrepreneurship is a relatively new and poorly understood concept. Policy promotes generating community activity, particularly in rural areas, for health and social benefits and ‘community resilience’. Rural health professionals might be well placed to generate community activity due to their status and networks. This exploratory study, conducted in rural Tasmania and the Highlands and Islands of Scotland considered whether rural health professionals act as social entrepreneurs. We investigated activities generated and processes of production. Thirty-eight interviews were conducted with general practitioners, community nurses, primary healthcare managers and allied health professionals living and working rurally. Interviewees were self-selecting responders to an invitation for rural health professionals who were ‘formally or informally generating community associations or networking that produced social outcomes’. We found that rural health professionals initiated many community activities with social outcomes, most related to health. Their identification of opportunities related to knowledge of health needs and examples of initiatives seen elsewhere. Health professionals described ready access to useful people and financial resources. In building activities, health professionals could simultaneously utilise skills and knowledge from professional, community member and personal dimensions. Outcomes included social and health benefits, personal ‘buzz’ and community capacity. Health professionals' actions could be described as social entrepreneurship: identifying opportunities, utilising resources and making ‘deals’. They also align with community development. Health professionals use contextual knowledge to envisage and grow activities, indicating that, as social entrepreneurs, they do not explicitly choose a social mission, rather they act within their known world-view. Policymakers could consider ways to engage rural health professionals as social entrepreneurs, in helping to produce resilient communities.

Can social support matter? The relationship between social support and mental health among bereaved parents in an only-child society: Evidence from China

Shidu parents (parents who lost their only child) experience poor mental health, and social support is expected to alleviate mental stress and facilitate mental adaptation of bereaved parents. However, the literatures on the effects of social support on mental health of bereaved parents have yield mixed outcomes, and the relationship between social support and mental health among Shidu parents has been unexplored in China. The purpose of this study was to examine the relationship between social support and mental health among Shidu parents in China. Multistage stratified random sampling was conducted to collect data in 2017, and a total of 1,750 Shidu parents were employed as the analytical sample. The Ordinary Least Squares Model and Instrumental Variables (IV) Method were both employed. The variable of community services for the aged provided by the market was employed as the IV of the study considering death taboo inveterately rooted in philosophies and religions in Chinese culture. The results indicated that there was a positive relationship between social support and mental health among Shidu parents, specifically, objective social support and social support utilisation were significantly related to mental health of Shidu parents, while subjective social support was not. Implications of the study include the following: First, it is crucial to help spouse and friends gain appropriate social support skills. Mutual associations can be an important source of social support. Second, objective social support should be given a top priority, and suitable amount, timing, source and structure of social support should be paid more attention to strengthen the ‘goodness of fit’ between the needs of Shidu parents and support provided. Third, some other social services such as community care, social work services and professional consulting services can be appropriate alternatives to alleviate mental stress of Shidu parents.     

Does health care spending improve health outcomes? Evidence from English programme budgeting data

Empirical evidence has hitherto been inconclusive about the strength of the link between health care spending and health outcomes. This paper uses programme budgeting data prepared by 295 English Primary Care Trusts to model the link for two specific programmes of care: cancer and circulatory diseases. A theoretical model is developed in which decision-makers must allocate a fixed budget across programmes of care so as to maximize social welfare, in the light of a health production function for each programme. This yields an expenditure equation and a health outcomes equation for each programme. These are estimated for the two programmes of care using instrumental variables methods. All the equations prove to be well specified. They suggest that the cost of a life year saved in cancer is about 13,100 pounds, and in circulation about 8000 pounds. These results challenge the widely held view that health care has little marginal impact on health. From a policy perspective, they can help set priorities by informing resource allocation across programmes of care. They can also help health technology agencies decide whether their cost-effectiveness thresholds for accepting new technologies are set at the right level.

Do adolescent leisure-time physical activities foster health and well-being in adulthood? Evidence from two British birth cohorts

BACKGROUND: Calls for public health initiatives to increase adolescent leisure-time physical activity suggest that increasing activity in this age group will reduce social inequalities in health. While the public health benefits of exercise are undisputed, there is little evidence on its role in reducing health inequalities. The paper examines the extent to which adolescent leisure-time physical activity promotes adult health and well-being and explores whether adolescent leisure-time physical activity can act to reduce health inequalities arising from material deprivation during childhood. METHODS: This is a longitudinal study of the 1958 British birth cohort followed from age 16 to age 33 years (N = 15,452) and the 1970 British birth cohort followed to age 30 years (N = 14,018). Adult self-rated general health and Malaise Inventory scores are regressed on self-reports of leisure time physical activity. Analyses are conducted separately for men and women controlling for adolescent body mass index (BMI) and psychosocial problems. RESULTS: There was a consistent relationship between leisure-time physical activity in adolescence and psychological well-being approximately 15 years later for both the cohorts. This relationship was independent of adolescent BMI and psychosocial problems. More physical activity in adolescence predicted better adult self-assessed health in the 1958 cohort only. Leisure-time physical activity did not affect inequalities in health. CONCLUSIONS: Policies aimed at increasing participation in leisure-time physical activities in youth may improve population health but are unlikely to prevent the development of social inequalities in health.     

How are individual-level social capital and poverty associated with health equity? A study from two Chinese cities

Background  

A growing body of literature has demonstrated that higher social capital is associated with improved health conditions. However, some research indicated that the association between social capital and health was substantially attenuated after adjustment for material deprivation. Studies exploring the association between poverty, social capital and health still have some serious limitations. In China, health equity studies focusing on urban poor are scarce. The purpose of this study is therefore to examine how poverty and individual-level social capital in urban China are associated with health equity.     

Is social capital the key to inequalities in health?

There has been vigorous debate between the "social capital" and "neomaterialist" interpretations of the epidemiological evidence regarding socioeconomic determinants of health. We argue that levels of income inequality, social capital, and health in a community may all be consequences of more macrolevel social and economic processes that influence health across the life course. We discuss the many reasons for the prominence of social capital theory, and the potential drawbacks to making social capital a major focus of social policy. Intervening in communities to increase their levels of social capital may be ineffective, create resentment, and overload community resources, and to take such an approach may be to "blame the victim" at the community level while ignoring the health effects of macrolevel social and economic policies.     

Does area-based social capital matter for the health of Australians? A multilevel analysis of self-rated health in Tasmania

BACKGROUND: Material circumstances and collective psychosocial processes have been invoked as potential explanations for socioeconomic inequalities in health; and, linking social capital has been proposed as a way of reconciling these apparently opposing explanations. METHODS: We conducted multilevel logistic regression of self-rated health (fair or poor vs excellent, very good, or good) on 14 495 individuals living within 41 statistical local areas who were respondents to the 1998 Tasmanian Healthy Communities Study. We modelled the effects of area-level socioeconomic disadvantage and social capital (neighbourhood integration, neighbourhood alienation, neighbourhood safety, social trust, trust in public/private institutions, and political participation), and adjusted for the effects of individual characteristics. RESULTS: Area-level socioeconomic disadvantage was associated with poor self-rated health (beta = 0.0937, P < 0.001) an effect that was attenuated, but remained significant, after adjusting for individual characteristics (beta = 0.0419, P < 0.001). Social trust was associated with a reduction in poor self-rated health (beta = -0.0501, p = 0.008) and remained significant when individual characteristics (beta = -0.0398, P = 0.005) were included. Political participation was non-significant in the unadjusted model but became significant when adjusted for individual characteristics (beta = -0.2557, P = 0.045). The effects of social trust and political participation were attenuated and became non-significant when area-level socioeconomic disadvantage was included. CONCLUSION: Area-based socioeconomic disadvantage is a determinant of self-rated health in Tasmania, but we did not find an independent effect of area-level social capital. These findings suggest that in Tasmania investments in improving the material circumstances in which people live are likely to lead to greater improvements in population health than attempts to increase area-level social capital.     

Does the multidimensional nature of Super Profiles help district health authorities understand the way social capital affects health?

BACKGROUND: Social capital describes the notion that the social processes in an area can lead to benefits in health. As Super Profiles describe the social character of an area and they are easy for health authorities to use, they could provide a simple method for local assessment of how social organization affects health. METHODS: We calculated the expected mean birthweight for the enumeration districts of Birmingham based upon marital status, registration details of the child, year of birth, the mother's country of birth, fetal sex and deprivation as judged by the Townsend score using data from 138,696 live-born singleton births for the years 1986-1996 inclusive. We classified enumeration districts into Target Markets, derived from Super Profiles. For each Target Market, we calculated the observed mean birthweight and the difference and 95 per cent confidence interval between the observed and expected birthweights. We used information in Super Profiles to speculate about the social processes that led to some Target Markets having mean birthweights that were significantly different from those expected. RESULTS: Fifteen of the 40 Target Markets had significant differences between predicted and observed mean birthweight, but these differences were less than 50 g. There were no common characteristics of Target Markets that were consistently advantageous for birthweight and none that were disadvantageous. CONCLUSION: The information in the Super Profiles does not illuminate the way that social processes affect health, and the variation in mean birthweight between areas explained by social processes as measured by Super Profiles is small.     

Does Regular Physical Activity Improve Personal Income? Empirical Evidence from China

A lack of adequate exercise threatens human health, weakening human capital accumulation. The relationship between exercise and income has become the focus of attention in health economics. In terms of reducing body weight and improving physical fitness, diet and physical exercise are intertwined and become effective ways to shape a healthy state. Based on individual-level survey data from China, this study quantified the economic returns of habitual exercise behavior by using an endogenous switching regression model (ESRM) to eliminate selection bias. The study shows that (1) participants in the group with regular exercise behavior increased their income by 3.79% compared with those not exercising regularly; (2) for the group with no regular exercise behavior, regular exercise increased their income by 13.36% compared with those not exercising regularly. Additionally, empirical evidence shows that both drinking and smoking can significantly increase individual income, despite unhealthy habits. These results suggest that the habit of regular physical activity plays a vital role in increasing individual income and improving overall national health, and the effect of individual behavior on income is affected by national culture. The outcomes are empirical evidence for the Chinese government to promote Healthy China Action and support developing countries worldwide to enable habitual exercise, stimulating a policy of exercise behavior.     

Is social capital associated with HIV risk in rural South Africa?

The role of social capital in promoting health is now widely debated within international public health. In relation to HIV, the results of previous observational and cross-sectional studies have been mixed. In some settings it has been suggested that high levels of social capital and community cohesion might be protective and facilitate more effective collective responses to the epidemic. In others, group membership has been a risk factor for HIV infection. There have been few attempts to strengthen social capital, particularly in developing countries, and examine its effect on vulnerability to HIV. Employing data from an intervention study, we examined associations between social capital and HIV risk among 1063 14 to 35-year-old male and female residents of 750 poor households from 8 villages in rural Limpopo province, South Africa. We assessed cognitive social capital (CSC) and structural social capital (SSC) separately, and examined associations with numerous aspects of HIV-related psycho-social attributes, risk behavior, prevalence and incidence. Among males, after adjusting for potential confounders, residing in households with greater levels of CSC was linked to lower HIV prevalence and higher levels of condom use. Among females, similar patterns of relationships with CSC were observed. However, while greater SSC was associated with protective psychosocial attributes and risk behavior, it was also associated with higher rates of HIV infection. This work underscores the complex and nuanced relationship between social capital and HIV risk in a rural African context. We suggest that not all social capital is protective or health promotive, and that getting the balance right is critical to informing HIV prevention efforts.
