Social capital and self-rated health: Results from the US 2006 social capital survey of one community

Child health and its effect on adult social capital accumulation

Although studies have demonstrated important effects of poor health in childhood on stocks of human and health capital, little research has tested economic theories to investigate the effect of child health on social capital in adulthood. Studies on the influence of child health on adult social capital are mixed and have not used sibling fixed effects models to account for unmeasured family and genetic characteristics, that are likely to be important. Using the Add-Health sample, health in childhood was assessed as self-rated health, the occurrence of a physical health condition or mental health condition, while social capital in adulthood was measured as volunteering, religious service attendance, team sports participation, number of friends, social isolation, and social support. We used sibling fixed effects models, which attenuated several associations to non-significance. In sibling fixed effects models there was significant positive effects of greater self-rated health on participation in team sports and social support, and negative effect of mental health in childhood on social isolation in adulthood. These results suggest that children with poor health require additional supports to build and maintain their stock of social capital and highlight further potential benefits to efforts that address poor child health.

The role of health and health systems in promoting social capital, political participation and peace: A narrative review

High levels of violence and insecurity are highly detrimental for societies. United Nations Sustainable Development Goal 16 is advocating for peaceful, accountable and inclusive institutions as one powerful channel to foster global development. Investing in health and health policies can potentially contribute achieving these objectives. After providing a conceptual framework, this article reviews the existing literature on the evidence of the role of health and health systems in promoting social capital and trust, political engagement and participation, and peace that closely relate to the objectives of Sustainable Development Goal 16. We provide evidence of a systematically positive impact of better physical and mental health on social capital, and on political participation, both contributing to the sustainability of inclusive democratic institutions. We also document that health and health systems can help supporting peace, both via the reduction of social inequality and grievances, and by reducing the disruptive effects of epidemic shocks. Overall, the study provides evidence that health and health systems can generate co-benefits outside the health domain by promoting social capital, political participation and peace.

The effect of environmental degradation on self-reported health: the role of renewable energy consumption

Although there are a number of studies in the literature that have explored the effect of environmental degradation on the subjective well-being and life satisfaction, no previous study has addressed the role of renewable energy consumption in examining the effect of environmental degradation on self-reported health. To this end, we employ a conditional mixed process (CMP) model, using a unique dataset that combines both micro-level data from the 6th (2010-2014) and 7th (2017-2022) Waves of the World Values Survey (WVS) database and macro-level data from the World Bank. Our study has several important empirical findings. First, while environmental degradation deteriorates self-reported health, social capital and health expenditure have a positive impact on self-reported health. Second, the share of renewable energy consumption in total final energy consumption has a statistically significant negative impact on environmental degradation. Third, urbanization has a deteriorating effect on environmental quality and the total number of people increases environmental degradation.

The Relationship between Neighborhood Social Capital and the Health of Chinese Urban Elderly: An Analysis Based on CHARLS2018 Data

There is growing interest in the relationship between neighborhood social capital and the health of urban older people, but existing research still falls short in exploring the relationship between the two. Based on 2018 CHARLS data, this paper quantitatively examines the association between neighborhood social capital and the self-rated health of urban older people. The study found that, after controlling for a series of variables, both increased social interaction and increased frequency of social interaction significantly improved urban older people's self-rated health. To implement the Health China strategy and improve the health of urban older people, further attention should be paid to the role of neighborhood social capital, creating a harmonious environment for neighborhood interaction and promoting the cultivation of neighborhood social capital.

Social Capital and Self-Rated Health: A Cross-Sectional Study among Rural Japanese Working Residents

Social capital is positively associated with self-rated health; however, this association among workers is still unclear. Thus, this study examined the relationship between social capital and self-rated health with special attention to the employment type. A cross-sectional survey was conducted with 6160 workers aged 20-64 years from two towns in Mie Prefecture in January-March 2013. Social capital was assessed using five items in 4816 income-earning workers. The social capital scores were summed and then divided into three groups. The self-rated health responses were dichotomised into 'poor' and 'good'. The association was examined using a stepwise binomial logistic regression stratified by employment type and adjusted for potential confounders. Regular employees with low social capital had a higher significant odds ratio of poor self-rated health than medium (OR 0.58 95% CIs 0.39-0.87) and high (OR 0.39; 95% CIs 0.26-0.59) social capital levels after controlling for all potential confounders. Similar patterns were observed for non-regular employees with medium and high social capital. There was a significant relationship between some indicators of social capital and poor self-rated health among self-employees. These results highlight that social capital acts as an unequal health resource for different types of workers.

Socioenvironmental factors and behaviors associated with negative self-rated health in Brazil

The purpose of this study is to determine the factors associated with negative self-rated health in Brazil. The sample consisted of 5,259 adults from five representative capitals of the five regions of Brazil. Data collection was achieved in the following municipalities: Palmas (North Region), João Pessoa (Northeast Region), Goiânia (Central-West Region), Vitória (Southeast Region) and Florianópolis (South Region). For the analysis of the data, Binary Logistic Regression for determine the factors associated with negative self-rated health was used. Negative self-rated health was identified in 31.43% of Brazilians. The factors that were significantly associated were bad air quality, does not have public spaces for leisure, older age group, insufficient salary to cover expenses, a rare practice of physical exercises, does not perform healthy eating, active commuting for study or employment and commuting time for above 30 minutes, dissatisfaction with health services and still, not working, not looking for a job and finally, reside in some Brazilian regions. The study presents the importance of socioenvironmental and behavioral factors for the self-rated health of Brazilian adults, as well as it shows high rates of negative self-rated health compared to other studies.

The Association of Social Capital and Self-Rated Health Between Urban Residents and Urbanized Rural Residents in Southwest China

China has seen an accelerated process of urbanization in the past 30 years. The influence of urbanization on health is complex and primarily influenced by changes in social capital. The purpose of this research was to compare the social capital between urban residents and urbanized rural residents of southwest China and its relationship with self-rated health. It is of great significance to study the difference of social capital between urban and urbanized rural residents to help urbanized rural residents improve their social adaptability and health. Data was collected from 1,646 residents between November and December of 2017 in Chengdu. Three logistic regressions were used to investigate the association between social capital and self-rated health by controlling for demographic variables, lifestyles factors, and health status factors. We observed that urban residents' self-rated health had a higher proportion of “good” than that of urbanized rural residents (P = 0.017). After controlling for factors such as health status and demographic characteristics, participants with higher social capital had better self-rated health. Urbanized rural residents with higher community trust and belonging had better self-rated health (OR = 0.701, 95% CI = 0.503~0.978), however urban residents with higher personal social networks and family relationships had better self-rated health (OR = 0.676, 95% CI = 0.490~0.933 and OR = 0.666, 95% CI = 0.450~0.987, respectively). Different types of communities should focus on the types of social capital from different sources, so as to take more targeted measures to improve the social support of residents and improve their health. Improving residents' social trust and sense of belonging may help urbanized rural residents better adapt to the new living environment and help them complete the identity transformation.

Social Capital and Self-Rated Health among Older Adults Living in Urban China: A Mediation Model

Social capital and healthy aging are both crucial for social sustainability in China. The present study tested the role of structural social capital in self-rated health among older urban Chinese adults and the influence of cognitive social capital on this relationship. A sample of 456 older adults aged 60 or older in Suzhou, China, were recruited and completed the survey in 2015. Structural equation modeling was used to test the proposed model. Cognitive social capital had larger effects on self-rated health than structural social capital. The relationship between structural social capital and self-rated health was fully mediated by cognitive social capital, when sociodemographic characteristics, socioeconomic status, physical health conditions, and living arrangements were controlled. The culturally sensitive latent construct of community-based social capital proved to be a valid instrument in urban Chinese contexts. Structural social capital likely indirectly affects self-rated health through cognitive social capital. Policy and intervention implications are discussed.

Examining the relationship between U.S. incarceration rates and population health at the county level

A collateral consequence of mass incarceration in the United States is its negative effects on population health. Using data from 2015, this study examines the relationship between incarceration rates and population health for a national sample of U.S. counties. To obtain unbiased estimates of the effect of incarceration on health, we use multivariate models which account for the endogeneity of incarceration rates when determining their effect on population health by employing an instrumental variable approach where the robust instrumental (exogenous) variable per capita corrections expenditures is used to predict incarceration rate. We then estimate population health outcomes as a function of predicted incarceration rate alongside factors such as public health spending, indicators of health behavior and control variables in models explaining county-level population health. Consistent with findings from prior research on individuals, families and at the state level, results of our analyses indicate that higher levels of incarceration are associated with higher levels of both morbidity (percentage reporting fair or poor health) and mortality (life expectancy). Implications of these findings for health and criminal justice policy, as well as research, are considered.

Social capital and physical health: An updated review of the literature for 2007-2018

PURPOSE

Social capital is frequently indicated as a determinant of population health. Despite an increase in the frequency of public health studies including such measures, our understanding of social capital's effects on health remains unclear. In 2008, a systematic review of the "first decade" of research on social capital and health was published in the textbook Social Capital and Health. Our study intends to update and expand upon this original review to account for developments in the literature over the second decade of research on social capital and health.

METHODS

We employed a systematic review of empirical studies investigating the relationship between measures of social capital and physical health outcomes published between January 1, 2007 and December 31, 2018. To identify potential studies, we conducted searches of PubMed, Embase, and PsychINFO databases in January 2019 using combinations of "social capital" and "physical health" search terms.

RESULTS

We identified 1,608 unique articles and reviewed 145 studies meeting our inclusion criteria. The most frequently examined health condition was self-reported health (57%), followed by mortality (12%), cardiovascular diseases (10%), obesity (7%), diabetes (6%), infectious diseases (5%), and cancers (3%). Of these studies, 127 (88%) reported at least partial support for a protective association between social capital and health. However, only 41 (28%) reported exclusively positive findings. The majority (59%) of results were mixed, suggesting a nuanced relationship between social capital and health. This finding could also be indicative of differences in study design, which showed substantial variation.

CONCLUSIONS

Despite limitations in the literature, our review chronicles an evolution in the field of social capital and health in terms of size and sophistication. Overall, these studies suggest that social capital may be an important protective factor for some physical health outcomes, but further research is needed to confirm and clarify these findings.

Social capital: Implications for neurology

Social capital (SC) is a broad term that encompasses the many resources derived from social connections. The contemporary study of SC in public health has deep roots in the related fields of sociology, economics, and politics. Its multidisciplinary nature and the varying potential ways it could affect individuals have resulted in different but overlapping models to approach SC in the health field. There are currently no standardized measures of SC, and even more challenging its impact on health outcomes seems to vary according to the level of analysis. Despite the accumulating evidence that supports a protective effect of SC on mental and physical health, and mortality, not enough attention has been paid to the potential drawbacks of SC. The role of SC in neurological disease is just beginning to be explored. Concerted efforts are needed to ensure that empirical evidence on SC could be properly translated into interventions for health-promoting purposes. In this paper, we review the current state of scientific knowledge on the subject of SC, with a focus on its application in the field of neurology.

Self-rated health and endogenous selection into primary care

This study assesses the causal effects of primary care utilization on subjective health status in Turkey using individual-level data from the 2012 Health Research Survey. Employing recursive bivariate ordered models that take into account the possibility that selection into healthcare might be correlated with the respondent's self-reported health status, we find that selection into primary care is endogenously determined and that the utilization of primary care significantly improves self-rated health after controlling for sociodemographics, socioeconomic status, health behaviors and risk factors, and access to healthcare. We show that the causal association between healthcare utilization and health status is robust to the use of objective measures of health and specific types of care, suggesting that the use of a single-item question on self-rated health and binary measures of preventive care utilization is valid.

Class and Health Inequality in Later Life: Patterns, Mechanisms and Implications for Policy

The growth of the post-retirement population, which has occurred as a result of rapid growth in life expectancy coupled with the ageing of the baby boomer cohort, has led to significant concern. This concern, however, typically neglects the heterogeneity of later life experiences and how these are patterned by inequalities that reflect how process of social stratification continue to operate into later life. This paper draws on a programme of work, based on analysis of the English Longitudinal Study of Ageing, to empirically examine questions of inequality in later life. It begins by illustrating the patterning of health inequality. It then investigates the importance of later life contexts and events in shaping inequality through and after the retirement process. In doing so it examines the extent to which later life continues to reflect stable social structures that shape inequalities and, consequently, health and wellbeing in later life. The paper then illustrates how the effects of socioeconomic position on health in later life can be theorised as a product of class processes, borrowing in part from Bourdieu. Other dimensions of inequality, such as gender, ethnicity, area and sexuality, are not discussed here. The paper concludes with a discussion of the need for a close focus on inequalities in later life in research, policy and practice.

Social participation and self-rated psychological health: A longitudinal study on BHPS

Although social capital has been hypothesized to have positive influence on psychological health, a relationship between social capital dimensions and psychological wellbeing has rarely been found. This longitudinal study investigates the relationship between social participation in associations and self-rated psychological health. The paper uses five waves of the British Household Panel Survey (BHPS) from 1991 to 1995 (unbalanced panel N=45,761). Ordered logit fixed effect methods were used to study the longitudinal link between structural social capital (being a member, active, and both a member and active in associations) and self-rated psychological health assessed by single items of the General Health Questionnaire (GHQ-12) controlling for age, marital status, household size, number of children, education, income, economic status, number of visits to the GP and health problems. The paper shows that being only a member and only active in associations has no statistical relationship with almost all the items of the GHQ-12. Instead, being both a member and active in associations is linked to all "positive" items of self-rated psychological health and to two main "negative" items of psychological wellbeing. These findings highlight the protective role of being both a member and active in associations against poor psychological health outcomes.

Social capital and health in China: exploring the mediating role of lifestyle

Background

Although social capital as a key determinant of health has been well established in various studies, little is known about how lifestyle factors mediate this relationship. Understanding the cross-relationships between social capital, health, and lifestyle factors is important if health promotion policies are to be effective. The purpose of this study is to explore whether different dimensions of social capital and lifestyle factors are related, and whether lifestyle factors mediate the association between social capital and self-rated health (SRH) and psychological well-being (PWB) in China.

Methods

This study used nationally representative data from the 2014 China Family Panel Studies (n = 28,916). The data reported on three dimensions of individual-level social capital: social trust, social relationship and Chinese Communist Party (CCP) membership. Health was assessed using SRH and PWB. Five lifestyle indicators were recorded: healthy diet, physical activity, smoking, sleeping, and non-overweight status. Logistic regression was used to examine the associations between social capital and lifestyle factors, and whether there was a mediating role of lifestyle. Odds ratios relating health status to social capital were reported before and after adjustment for lifestyle factors. Mediation analysis was then used to calculate the total, direct and indirect effects of social capital on SRH and PWB.

Results

The results show that social trust was significantly associated with all five lifestyle factors. Social relationship was significantly associated with four of the five: healthy diet, physical activity, sleeping and non-overweight. CCP membership was only significantly associated with two lifestyle factors: physical activity and non-overweight. Social trust and social relationship were significantly related to both SRH and PWB. CCP membership was only significantly related to SRH. Mediation analysis found modest evidence that lifestyle factors influenced the relationship between all three types of social capital and SRH. In contrast, only social trust and social relationship, but not CCP membership, were mediated by lifestyle factors with respect to PWB.

Conclusions

This study is the first to explore the mediating role of lifestyle factors in the relationship between social capital and health in China. The overall findings suggest that lifestyle factors modestly mediate the association between social capital and health. The degree of mediating effect varies across different dimensions of social capital. Social capital-based health promotion policies would benefit from taking lifestyle factors into account.

Self-rated health, generalized trust, and the Affordable Care Act: A US panel study, 2006-2014

Previous research shows that generalized trust, the belief that most people can be trusted, is conducive to people's health. However, only recently have longitudinal studies suggested an additional reciprocal pathway from health back to trust. Drawing on a diverse body of literature that shows how egalitarian social policy contributes to the promotion of generalized trust, we hypothesize that this other 'reverse' pathway could be sensitive to health insurance context. Drawing on nationally representative US panel data from the General Social Survey, we examine whether the Affordable Care Act of 2010 could have had influence on the deteriorating impact of worsening self-rated health (SRH) on generalized trust. Firstly, using two-wave panel data (2008-2010, N = 1403) and employing random effects regression models, we show that a lack of health insurance coverage negatively determines generalized trust in the United States. However, this association is attenuated when additionally controlling for (perceived) income inequality. Secondly, utilizing data from two separate three-wave panel studies from the US General Social Survey (2006-10; N = 1652; 2010-2014; N = 1187), we employ fixed-effects linear regression analyses to control for unobserved heterogeneity from time-invariant factors. We demonstrate that worsening SRH was a stronger predictor for a decrease in generalized trust prior (2006-2010) to the implementation of the Affordable Care Act. Further, the negative effect of fair/poor SRH seen in the 2006-2010 data becomes attenuated in the 2010-2014 panel data. We thus find evidence for a substantial weakening of the previously established negative impact of decreasing SRH on generalized trust, coinciding with the most significant US healthcare reforms in decades. Social policy and healthcare policy implications are discussed.

Perceptions of community, social capital, and how they affect self-reported health: a multilevel analysis

OBJECTIVES

The link between social capital and self-reported health has been widely explored. On the other hand, we know less about the relationship between social capital, community socioeconomic characteristics, and non-social capital-related individual differences, and about their impact on self-reported health in community settings.

METHODS

Cross-sectional study design with a proportional sample of 7965 individuals from 20 US communities were analyzed using multilevel linear regression models, where individuals were nested within communities. The response rates ranged from 13.5% to 25.4%.

RESULTS

Findings suggest that perceptions of the community and individual level socioeconomic characteristics were stronger predictors of self-reported health than were social capital or community socioeconomic characteristics.

CONCLUSIONS

Policy initiatives aimed at increasing social capital should first assess community member's perceptions of their communities to uncover potential assets to help increase social capital.

Promoting social capital to alleviate loneliness and improve health among older people in Spain

Loneliness is especially frequent among older people in Southern Europe. Furthermore, promoting social capital to tackle loneliness and its health effects is an understudied intervention strategy. Therefore, a complex intervention was piloted in Spain in a pre-post study with a 2-year follow-up. Its aims were to explore the feasibility of the intervention and its short- and long-term effects. It was conducted in one mixed rural-urban and two urban areas of diverse socioeconomic levels from 2011 to 2012. The intervention framework was based on social capital theory applying a behaviour change model and care co-ordination. The intervention comprised: (i) a co-ordinated action aimed at building a network between primary healthcare centres and community assets in the neighbourhood and (ii) a group-based programme, which promoted social capital among lonely older people, especially social support and participation. Older people active in senior centres volunteered as gatekeepers. The main outcome domain was loneliness. Secondary outcome domains were participation, social support, self-perceived health, quality of life, depressive symptoms and use of health resources. Pre-post changes were assessed with t-test, Wilcoxon signed-rank test and McNemar's test. Differences between the three time points were assessed with a one-way ANOVA with repeated measures. Social workers and nurses were successfully involved as group leaders, 10 volunteers took part and 38 participants were included. After the intervention, loneliness decreased while social participation and support significantly increased. Furthermore, the number of visits to nurses increased. Exactly 65.8% of the participants built social contacts within the group and 47.4% became engaged in new activities. Two years later, social effects were maintained and depressive symptoms had decreased. Exactly 44.7% of the participants continued to be in contact with at least one person from the group and 39.5% continued participating. The intervention contributes a novel and feasible social capital-based approach for alleviating loneliness among older adults while prompting meaningful changes in their lives.

Patient-centered evaluation of home-based rehabilitation developed using community-based participatory research approach for people with disabilities: a case series

PURPOSE

The purpose of this study was to evaluate the effectiveness of the locally tailored and individualized home-based rehabilitation (HBR) program developed using the community-based participatory research (CBPR) approach, in terms of perceived health in patients with different levels of social engagement, and to explore the perceived facilitators and barriers to rehabilitation.

METHOD

A concurrent mixed-method design was employed. Four patients participated in the combined therapist- and self-delivered HBR program for 5 months. The perceived health outcomes were quantitatively assessed at baseline, after the therapist-delivered intervention period, and at 1 and 3 months after the self-delivered intervention period. Then, in-depth individual interviews were conducted to explore the facilitators and barriers to rehabilitation.

RESULTS

The perceived health of patients who were fully or partially engaged in society was increased during the therapist-delivered intervention period, and maintained the increased level during the self-delivered intervention period, whereas that of patients who were rarely or not engaged dropped again to lower than the baseline. These results were caused by differentiated facilitators and barriers to rehabilitation depending on the level of social engagement.

CONCLUSIONS

Applying tailored strategies to patients with differing levels of social engagement is recommended to further optimize the local relevance of the HBR program. Implications for rehabilitation A community-based participatory research approach can provide an opportunity to enhance local relevance through community-academic partnerships, in developing a home-based rehabilitation (HBR) program for the people with disabilities. For community therapists, enhancing the local relevance of the HBR program, applying tailored strategies to patients with differing levels of social engagement is recommended because the perceived health of the HBR program can be different owing to differing perceived facilitators and barriers to rehabilitation, depending on the level of social engagement. For patients with rare or no engagement in society, satisfying their need for interaction with the therapists and helping them cope with their wrong belief about the possibility of their recovery is important to encourage behavioral change and perceived physical improvements.

Social capital interventions targeting older people and their impact on health: a systematic review

BACKGROUND

Observational studies show that social capital is a protective health factor. Therefore, we aim to assess the currently unclear health impact of social capital interventions targeting older adults.

METHODS

We conducted a systematic review based on a logic model. Studies published between January 1980 and July 2015 were retrieved from MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials and Web of Science. We included randomised controlled trials targeting participants over 60 years old and focused on social capital or its components (eg, social support and social participation). The comparison group should not promote social capital. We assessed risk of bias and impact on health outcomes and use of health-related resources applying a procedure from the Canadian Agency for Drugs and Technologies in Health (CADTH) based on vote-counting and standardised decision rules. The review protocol was registered in PROSPERO (reference number CRD42014015362).

RESULTS

We examined 17 341 abstracts and included 73 papers reporting 36 trials. Trials were clinically and methodologically diverse and reported positive effects in different contexts, populations and interventions across multiple subjective and objective measures. According to sufficiently reported outcomes, social capital interventions showed mixed effects on quality of life, well-being and self-perceived health and were generally ineffective on loneliness, mood and mortality. Eight trials with high quality showed favourable impacts on overall, mental and physical health, mortality and use of health-related resources.

CONCLUSIONS

Our review highlights the lack of evidence and the diversity among trials, while supporting the potential of social capital interventions to reach comprehensive health effects in older adults.

How does social capital matter to the health status of older adults? Evidence from the China Health and Retirement Longitudinal Survey

This paper uses longitudinal data from China to examine the causal relationship between structural social capital and health among Chinese older adults. We employ various econometric strategies to control for the potential endogeneity of social capital and account for the possible contextual confounding effects by including community-level social capital. We use three indicators to measure individuals' general, physical, and mental health. Results indicate that social capital has a significant and positive effect on general and physical health. Based on our primary IV findings, a one standard-deviation increase in social capital leads to a 4.9 standard-deviation decrease in the probability of having bad health and a 2.2 standard-deviation decrease in physical activity limitations. Our results are robust to a series of sensitivity checks. Further analysis suggests heterogeneous effects by age but not by gender or area of residence.

Effect of Moderate to Vigorous Physical Activity Intervention on Improving Dementia Family Caregiver Physical Function: A Randomized Controlled Trial

OBJECTIVE

Alzheimer's disease and related dementias (ADRD) affect more than five million Americans and their family caregivers. Caregiving creates challenges, may contribute to decreased caregiver health and is associated with $9.7 billion of caregiver health care costs. The purpose of this 12 month randomized clinical trial (RCT) was to examine if the Enhancing Physical Activity Intervention (EPAI), a moderate to vigorous physical activity (MVPA) treatment group, versus the Caregiver Skill Building Intervention (CSBI) control, would have greater: (1) MVPA adherence; and (2) physical function.

METHODS

Caregivers were randomly assigned to EPAI or CSBI (N=211). MVPA was assessed using a self-report measure; and physical function was objectively assessed using two measures. Intention-to-treat analyses used descriptive, categorical and generalized estimating equations (GEE), with an exchangeable working correlation matrix and a log link, to examine main effects and interactions in change of MVPA and physical function over time.

RESULTS

At 12 months, EPAI significantly increased MVPA (p=<0.001) and number of steps (p=< .01); maintained stable caregiving hours and use of formal services; while CSBI increased hours of caregiving (p=<0.001) and used more formal services (p=<0.02). Qualitative physical function data indicated that approximately 50% of caregivers had difficulties completing physical function tests.

CONCLUSION

The EPAI had a stronger 12 month effect on caregiver MVPA and physical function, as well as maintaining stability of caregiving hours and formal service use; while CSBI increased caregiving hours and use of formal services. A study limitation included greater EPAI versus CSBI attrition. Future directions are proposed for dementia family caregiver physical activity research.

Gender differences in the association between cognitive social capital, self-rated health, and depressive symptoms: a comparative analysis of Sweden and Ukraine

Background

Social capital is one of the social determinants of health, but there is still a lack of studies comparing its significance for health in different cultural settings. This study investigates and compares the relations between individual cognitive social capital and depressive symptoms and self-rated health in Sweden and Ukraine for men and women separately.

Study design

Two cross-sectional nationally representative surveys of adult populations were used for the analysis. Data from the Ukraine’s World Health Survey and the Sweden’s National Public Health Survey were analyzed in this comparative study.

Methods

The independent variable, cognitive social capital, was operationalized as institutional trust and feelings of safety. Depressive symptoms and self-rated health were used as the outcome variables. Crude and adjusted odds ratios and the 95 % confidence intervals were calculated using logistic regression. The model also adjusted for socio-demographic and lifestyle variables.

Results

Institutional trust is higher in Sweden compared to Ukraine (31 % of the Swedes vs. 12 % of the Ukrainians reported high trust to their national government/parliament). There is a strong association between self-rated health and institutional trust for both sexes in Sweden (odds ratio/OR = 1.99; 95 % CI = 1.58–2.50 for women and OR = 1.82, CI = 1.48–2.24 for men who reported low institutional trust compared with those with high institutional trust) but only for women (OR = 1.88, CI = 1.12–3.15) in Ukraine. Trust thus seems to be more important for self-rated health of women and men in Sweden compared to their counterparts in Ukraine. Significant associations between depressive symptoms and institutional trust were not observed in either country after adjusting for socio-demographic and lifestyle factors. A lack of feeling of safety increased the odds of having depressive symptoms among women (OR = 1.97, CI = 1.41–2.76) and men (OR = 3.91, CI = 2.19–6.97) in Sweden. The same association was observed for poor self-rated health among Swedish women (OR = 2.15, CI = 1.55–2.99) and men (OR = 2.75, CI = 1.58–4.80). In Ukraine, a lack of feeling of safety did not show any significant association with self-rated health or depressive symptoms for men, but it increased the odds of depressive symptoms among women (OR = 1.72, CI = 1.13–2.62).

Conclusions

In general, individual cognitive social capital is higher in Sweden than in Ukraine, and there is a stronger association between cognitive social capital and self-rated health in Sweden than in Ukraine. Interventions aiming to increase cognitive social capital for health promoting purposes might be favorable in Sweden, but this is not evidently the case in Ukraine.

Racial Differences in Program Evaluation of a Lifestyle Physical Activity Randomized Controlled Trial

The purpose of this study was to compare program evaluation responses between African American and Caucasian caregivers of persons with Alzheimer's disease and related dementias who completed a lifestyle physical activity randomized controlled trial. The aim was to determine if African Americans evaluated the study differently than Caucasians. Family caregivers (N = 211) were randomly assigned to a 12-month physical activity intervention or a control condition. Upon intervention completion (n = 114), caregivers responded to an 11-item questionnaire using Likert-type scale responses and three open-ended questions about the overall intervention quality. Findings indicated that African American caregivers evaluated both conditions more favorably than Caucasian caregivers (p = .02). Content analysis of the narrative responses revealed five major qualitative themes: support, resources, responsibility, adjusting, and time These findings suggest the value of both access to resources, and support for African American caregivers who participate in intervention research.

Investigating the temporal relationship between individual-level social capital and health in fragile families

Background

The potential for social capital to influence health outcomes has received significant attention, yet few studies have assessed the temporal ordering between the two. Even less attention has been paid to more vulnerable populations, such as low-income women with children. Our objective was to explore how different dimensions of social capital impact future health status among this population.

Methods

This study uses data from the Fragile Families and Child Well-Being (FFCWB) Study, which has followed a cohort of children and their families born in large U.S. cities between 1998 and 2000 to mostly minority, unmarried parents who tend to be at greater risk for falling into poverty. Four separate measures of social capital were constructed, which include measures of social support and trust, social participation, perceptions of neighborhood social cohesion, and perceptions of neighborhood social control. The temporal effect of social capital on self-reported health (SRH) is investigated using logistic regression and we hypothesize that higher levels of social capital are associated with higher levels of self-rated health.

Results

After controlling for socioeconomic and demographic factors related to social capital and self-rated health, social support and trust, perceptions of neighborhood social cohesion and control at an earlier point in time were positively associated with higher levels of health four-years later. Social participation was not related to increased health. The empirical results appear robust.

Conclusion

Higher levels of social capital are predictive of improved health over a four-year time frame. These results suggest that policy initiatives supporting increasing the social capital available and accessible by low-income, urban, minority women are viable for improving health. Such policies may have the potential to reduce socioeconomic health disparities.

Longitudinal association between social capital and self-esteem: a matter of context

The aim of this study is to investigate the longitudinal association between indicators of different components of social capital at the individual, household, and area levels and self-esteem while adjusting for various confounders at multiple levels. Respondents participating in Wave 1 (2009) and 2 (2010) of the Seoul Welfare Panel Study were used in the analysis. The final sample for the current study includes a total of 5127 participants in 2738 households within 25 administrative areas. This study shows that only a small amount of variance in self-esteem was attributed to the area level (7.6%). On the other hand, a relatively large amount of variance in self-esteem was attributed to the household level (52.5%). It has also shown that all individual-level social capital indicators including perceived helpfulness, organizational participation, and volunteer work were positively associated with self-esteem. Among household-level indicators of social capital, only organizational participation was associated with self-esteem. However, none of the area-level social capital indicators were associated with self-esteem. The main finding of the current study suggested that the association between social capital and self-esteem varied depending on both dimensions and levels of social capital indicators.

Changes in access to structural social capital and its influence on self-rated health over time for middle-aged men and women: a longitudinal study from northern Sweden

Until recently, most studies on social capital and health have been cross-sectional making it difficult to draw causal conclusions. This longitudinal study used data from 33,621 individuals (15,822 men and 17,799 women) from the Västerbotten Intervention Program, to analyse how changes in access to individual social capital influence self-rated health (SRH) over time. Two forms of structural social capital, i.e. informal socializing and social participation, were measured. Age, sex, education, marital status, smoking, snuff, physical activity, alcohol consumption, high blood pressure, and body mass index were analysed as potential confounders. The association between changes in access to structural social capital and SRH in the follow-up was adjusted for SRH at baseline, as well as for changes in the socio-demographic and health-risk variables over time. The results support that changes in access to structural social capital over time impact on SRH. Remaining with no/low level of informal socializing over time increased the odds ratio for poor SRH for both men and women (OR of 1.45; 95%CI = 1.22-1.73 among men and OR of 1.56; 95%CI = 1.33-1.84 among women). Remaining with no/low levels of social participation was also detrimental to SRH in men and women (OR 1.14; 95%CI = 1.03-1.26 among men and OR 1.18; 95%CI = 1.08-1.29 among women). A decrease in informal socializing over time was associated with poor SRH for women and men (OR of 1.35; 95%CI = 1.16-1.58 among men and OR of 1.57; 95%CI = 1.36-1.82 among women). A loss of social participation had a negative effect on SRH among men and women (OR of 1.16; 95%CI = 1.03-1.30 among men and OR of 1.15; 95%CI = 1.04-1.27 among women). Gaining access to social participation was harmful for SRH for women (OR 1.17; 95%CI = 1.05-1.31). Structural social capital has complex and gendered effects on SRH and interventions aiming to use social capital for health promotion purposes require an awareness of its gendered nature.

Patterns and causes of health inequalities in later life: a Bourdieusian approach

This study explores the relationship between social class and health change in older people in a path analysis, using data from the English Longitudinal Study of Ageing (n = 6241) in a Bourdieusian theoretical framework. Bourdieu drew a distinction between the occupational characteristics by which people are classified and the secondary properties of class that relate to lifestyle (economic, cultural and social capitals). Our path model includes both occupational and secondary characteristics of objective social class as well as a measure of subjective social class. We investigate the effects of the predictors on change in three health outcomes (self-rated health, number of symptoms of depression and number of difficulties with the activities of daily living). The analysis adds to Bourdieusian research by showing how the effects of objective social class on health are partially mediated by perceived social status. It also adds to substantive research on the relationship between class and health by suggesting that class-related health inequalities do persist for older people, even for those who are not in paid employment. It suggests that a large amount of the effect of occupation on the health of older people is not direct but indirect; through their personal wealth and lifestyle.

The relationship between social capital and traffic law violations: Israeli Arabs as a case study

Social aspects of a community may be correlated with driver's involvement in road traffic accidents. This study focused on examining this association in the context of the social capital theory. A survey of 600 Arab drivers living in 19 towns and villages was conducted using a face-to-face interview. Structural equation modeling was applied to explore paths of associations between the model components. Most of the proposed relationships in the path model were found to be significant, where the model explained 37% of the variation. The results indicate that only volunteering and reciprocity have direct correlations with traffic law violations. While the other correlations (except political involvement), were mediated by attitudes toward traffic laws violation. Hence, it can be concluded that it is not always possible to generalize the positive mechanisms of the social capital theory, and in certain populations such as the Arab minority it can give undesirable results.

Association between social group participation and perceived health among elderly inhabitants of a previously methylmercury-polluted area

OBJECTIVE

This study attempted to clarify the association between participation in a social group and perceived health among elderly residents of a previously methylmercury-polluted area in Japan.

METHODS

We conducted a cross-sectional study using eligible subjects from the Shiranui Sea coastal area, where mercury poisoning due to daily intake of fish and shellfish had previously caused some residents to develop the neurological disorder "Minamata disease (MD)." In the present study, we selected subjects aged ≥65 years who had never been diagnosed with MD or applied for medical treatment compensation.

RESULTS

A logistic regression model after adjusting for confounding factors showed that membership in a hobby or volunteer group was associated with good perceived health (odds ratio 1.97, 95 % confidence interval 1.02-3.80).

CONCLUSION

Our results showed that the effects of membership in social groups on perceived health were not equal across all social groups, with only hobby- or volunteer-related groups having a positive effect on perceived health. Our findings suggested that promoting participation in a social group such as hobby- or volunteer-related groups can help improve perceived health among elderly individuals who had experienced environmental pollution incidents.

"El lado oscuro": "the dark side" of social capital in Mexican American heroin using men

This article describes social capital in a cohort of 227 Mexican American men who are long-term injection heroin users. Social capital scores for current and former users were similar, suggesting equal absolute values of capital, but associated with illicit activities in current users and with cessation efforts in former users. Stable drug-using relationships provided high negative capital, whereas conventional relationships provided positive capital. Thus, social capital functions dichotomously in positive and negative contextualized roles. This study provides an alternative understanding of the dynamic interactions between individuals, environment, and drug abuse and can inform prevention and treatment interventions for an important demographic group.

Social capital and under-utilization of medication for financial reasons among elderly women: evidence from two Brazilian health surveys

This cross-sectional study assesses the prevalence and examines the role of social and demographic factors, health conditions, health system characteristics and contextual factors of under-utilization of medication for financial reasons among elderly women. Participants in the Greater Metropolitan Belo Horizonte Health Survey (GMBH) and the eleventh phase of the Bambuí Cohort Study of the Elderly were assessed. Among elderly women in the GMBH, the prevalence of under-utilization was 11.4%, and in Bambuí, the rate was 5.4%. Self-perception of health (OR, 3.46; 95%CI, 1.32_9.10); daily life limitations (OR, 2.75; 95% CI, 1.31-5.78) and perception of help (OR, 2.36; 95% CI, 1.07-5.25) had independent associations with under-utilization among GMBH residents. A poor perception of both cohesion in the neighborhood (OR, 2.38; 95% CI, 1.02-5.56) and the physical environment (OR, 2.58; 95% CI, 1.10-6.03) significantly increased the likelihood of under-utilization among Bambuí residents. These results provide important clues to identifying possible risk factors for under-utilization, highlighting the need to develop strategies targeting the amplification of the involvement between elderly women and their community to reduce the extent of under-utilization in later life.

Religious orientation and health among active older adults in the United States

This study utilizes a combination of intrinsic and extrinsic Religious Orientation Scales to explore the connection between religion and health in a sample of physically active, older adults. The revised Religious Orientation Scale and the RAND Short Form 36 (SF-36) were adopted to relate religious orientation (intrinsic, extrinsic, pro-religious, and non-religious) and self-rated mental and physical health status. Individuals of pro-religious orientation reported significantly worse health for physical functioning, role limitations due to physical health, and energy or fatigue when compared with those of all other religious orientations; however, no dose-response relationships were found between religious orientation and self-rated health. The results of this study indicate that deleterious health effects may accompany pro-religious orientation. Caution is provided for directors of religious programs for older adults.

Testing the association between social capital and health over time: a family-based design

BACKGROUND

The past decade has seen a vast increase in empirical research investigating associations between social capital and health outcomes. Literature reviews reveal 'generalized trust' and 'social participation' to be the most robust of the commonly used social capital proxies, both showing positive association with health outcomes. However, this association could be confounded by unmeasured factors, such as the shared environment. Currently, there is a distinct lack of social capital research that takes into account such residual confounding.

METHODS

Using data from the United Kingdom's British Household Panel Survey (BHPS) (waves thirteen to eighteen, N = 6982), this longitudinal, multilevel study investigates the validity of the association between trust, social participation and self-rated health using a family-based design. As the BHPS samples on entire households, we employed 'mean' and 'difference from the mean' aggregate measures of social capital, the latter of which is considered a social capital measurement that is not biased by the shared environment of the household. We employed Generalized Estimating Equations for all analyses, our two-level model controlling for correlation at the household level.

RESULTS

Results show that after adjusting for the shared environment of the household over a six year period, the association between social participation and self-rated health was fully attenuated (OR = 0.97 (95% confidence interval 0.89-1.06)), while the association with trust remained significant (OR = 1.11 (1.02-1.20)). Other health determinants, such as being a smoker, having no formal qualifications and being unemployed maintain their associations with poor self-rated health.

CONCLUSIONS

The association between social capital (specifically trust and social participation) and self-rated health appear to be confounded by shared environmental factors not previously considered by researchers. However, the association with trust remains, adding to existing empirical evidence that generalized trust may be an independent predictor of health.

Neighborhood social capital, neighborhood attachment, and dental care use for Los Angeles Family and Neighborhood Survey adults

OBJECTIVES

We tested the hypothesis that neighborhood-level social capital and individual-level neighborhood attachment are positively associated with adult dental care use.

METHODS

We analyzed data from the 2000-2001 Los Angeles Family and Neighborhood Survey that were linked to US Census Bureau data from 2000 (n = 1800 adults aged 18-64 years across 65 neighborhoods). We used 2-level hierarchical logistic regression models to estimate the odds of dental use associated with each of 4 forms of social capital and neighborhood attachment.

RESULTS

After adjusting for confounders, the odds of dental use were significantly associated with only 1 form of social capital: social support (adjusted odds ratio [AOR] = 0.85; 95% confidence interval [CI] = 0.72, 0.99). Individual-level neighborhood attachment was positively associated with dental care use (AOR = 1.05; 95% CI = 1.01, 1.10).

CONCLUSIONS

Contrary to our hypothesis, adults in neighborhoods with higher levels of social capital, particularly social support, were significantly less likely to use dental care. Future research should identify the oral health-related attitudes, beliefs, norms, and practices in neighborhoods and other behavioral and cultural factors that moderate and mediate the relationship between social capital and dental care use.

Health co-benefits and risks of public health adaptation strategies to climate change: a review of current literature

Objectives

Many public health adaptation strategies have been identified in response to climate change. This report reviews current literature on health co-benefits and risks of these strategies to gain a better understanding of how they may affect health.

Methods

A literature review was conducted electronically using English language literature from January 2000 to March 2012. Of 812 articles identified, 22 peer-reviewed articles that directly addressed health co-benefits or risks of adaptation were included in the review.

Results

The co-benefits and risks identified in the literature most commonly relate to improvements in health associated with adaptation actions that affect social capital and urban design. Health co-benefits of improvements in social capital have positive influences on mental health, independently of other determinants. Risks included reinforcing existing misconceptions regarding health. Health co-benefits of urban design strategies included reduced obesity, cardiovascular disease and improved mental health through increased physical activity, cooling spaces (e.g., shaded areas), and social connectivity. Risks included pollen allergies with increased urban green space, and adverse health effects from heat events through the use of air conditioning.

Conclusions

Due to the current limited understanding of the full impacts of the wide range of existing climate change adaptation strategies, further research should focus on both unintended positive and negative consequences of public health adaptation.

The health implications of civic association in Russia

Can civic and political participation influence health outcomes, and if so, does the general aversion to joining community activities have some connection to poor health outcomes in Russia? Using data from surveys of 18,000+ urban Russians conducted from 2003 to 2005 and controlling for a wide range of variables, we find that individuals who join collective civic and political activities report better health than non-joiners and that living in a participatory community may enhance one's health, regardless of one's own participation.

Multiple trajectories of successful aging of older and younger cohorts

PURPOSE

The purpose of this study was to apply group-based trajectory analysis to identify multiple successful aging trajectories by multiple indicators and to examine the factors related to successful aging among the elderly population in Taiwan.

DESIGN AND METHODS

Nation-representative longitudinal data collected from 1993 to 2007 and consisting of 2 cohorts were used, and the trajectories of the following 6 successful aging indicators were analyzed: chronic diseases, physical function difficulties, depressive symptoms, social support, social participation, and economic satisfaction.

RESULTS

Members of the cohorts fell into 4 groups: successful aging, usual aging (the older cohort)/insecure aging (the younger cohort), health declining, and care demanding. Successful aging trajectories reflected differences in self-rated health and life satisfaction.

IMPLICATIONS

This study provides empirical findings of the heterogeneity of successful aging trajectories in multidimensional indicators.

Social Capital and Human Mortality: Explaining the Rural Paradox with County-Level Mortality Data

The "rural paradox" refers to standardized mortality rates in rural areas that are unexpectedly low in view of well-known economic and infrastructural disadvantages there. We explore this paradox by incorporating social capital, a promising explanatory factor that has seldom been incorporated into residential mortality research. We do so while being attentive to spatial dependence, a statistical problem often ignored in mortality research. Analyzing data for counties in the contiguous United States, we find that: (1) the rural paradox is confirmed with both metro/non-metro and rural-urban continuum codes, (2) social capital significantly reduces the impacts of residence on mortality after controlling for race/ethnicity and socioeconomic covariates, (3) this attenuation is greater when a spatial perspective is imposed on the analysis, (4) social capital is negatively associated with mortality at the county level, and (5) spatial dependence is strongly in evidence. A spatial approach is necessary in county-level analyses such as ours to yield unbiased estimates and optimal model fit.

The importance of addressing social determinants of health at the local level: the case for social capital

Social determinants are gaining momentum in public health practice. Many proposed solutions for tackling social determinants are outside the scope of local public health professionals. This article reviews the literature to find possible moderating variables which may buffer the effects of the social determinants of health at the local level, and allow social determinants to be addressed within the purview of local health departments. The systematic approach employed for this article entailed searches of electronic academic databases (PubMed, EBSCO and Medline) and additional searches using Internet search engines and relevant websites for articles published between 1,975 and May 2010. The search revealed 2,554 articles, and 36 were determined appropriate for inclusion. The purpose of the search was to identify published articles relating to social determinants of health, social capital and effective approaches for addressing both at the level of the local health department. The search was then expanded to include unpublished material, to include the perspectives of local health departments. This process resulted in the inclusion of content from five sources. In this article, the case is made for focusing on social capital interventions to mitigate health problems associated with social determinants. Examples of successful interventions are provided to aid public health professionals in developing locale-specific solutions for addressing social determinants.

Perceptions of social capital and cost-related non-adherence to medication among the elderly

The aim of this study was to examine the association between social capital and cost-related non-adherence (CRN) in an elderly population, using data from 1,134 respondents to the Greater Metropolitan Belo Horizonte Health Survey. CRN was lower for those elderly with a better perception of attachment to their neighbourhoods (PR = 0.68; 95%CI: 0.50-0.94), with more social contacts (one to five, PR = 0.49; 95%CI: 0.30-0.80 and more than five, PR = 0.42; 95%CI: 0.26-0.67), and with private health insurance coverage (PR = 0.64; 95%CI: 0.45-0.93). Meanwhile, CRN was significantly higher for those with fair to poor self-rated health (PR =1.66; 95%CI: 0.95-2.90 and PR = 2.62; 95%CI: 1.46-4.71 respectively), with multiple comorbidities (two, PR = 3.45; 95%CI: 1.38-8.62 and three or more, PR = 4.42; 95%CI: 1.74-11.25), and with a lower frequency of physician-patient dialogue about health/treatment (rarely/never, PR = 1.91; 95%CI: 1.16-3.13). These findings highlight the need to take into account the social context in future research on CRN.

Community health promotion: a framework to facilitate and evaluate supportive social environments for health

The evaluation of community health promotion designed to create supportive social environments for health is still in its infancy. There is a lack of consensus on concepts, a lack of information on interventions that bring about social change, and a lack of feasible methods and tools. Consequently, the effectiveness of community health promotion may not be evaluated under all relevant headings. Therefore, this study aims to contribute to the evaluation of change in the social environment by presenting a framework. On the basis of the relevant literature we describe the relation between social environment and health predicting mediators. We selected participation and collaboration as core concepts in moderating the social environment of health because these terms give insight into the actual dynamics of health promotion practice. We synthesize the results into a framework with operational variables and offer four guidelines on how to apply the framework: use the variables as a menu, set specific aims for social change processes, use an action research approach, and triangulate data. The framework and guidelines enable the start-up, facilitation and evaluation of social change and learning processes and provide common ground for researchers and practitioners to improve the practice of their professions.

Dying of corruption

In many poor countries, over 80% of the population have experienced corrupt practices in the health sector. In rich countries, corruption takes other forms such as overbilling. The causal link between low levels of the quality of government (QoG) and population health can be either direct or indirect. Using cross-sectional data from more than 120 countries, our findings are that more of a QoG variable is positively associated with higher levels of life expectancy, lower levels of mortality rates for children and mothers, higher levels of healthy life expectancies and higher levels of subjective health feelings. In contrast to the strong relationships between the QoG variables and the health indicators, the relationship between the health-spending measures and population health are rather weak most of the time and occasionally non-existent. Moreover, for private health spending as well as for private share of total health spending, the relation to good health is close to zero or slightly negative. The policy recommendation coming out of our study to improve health levels around the world, in rich countries as well as in poor countries, is to improve the QoG and to finance health care with public, not private, money.

"Well, it's nobody's responsibility but my own." A qualitative study to explore views about the determinants of health and prevention of knee pain in older adults

BACKGROUND

Dahlgren and Whitehead's 'rainbow' outlines key determinants of health and has been widely adopted within public health policy and research. Public understanding regarding the determinants of health is, however, relatively unknown, particularly in relation to common chronic joint problems like knee pain. We aimed to explore individual attitudes to the prevention of knee pain, and assess how people make sense of their lives by using the rainbow model to explore social determinants of health.

METHODS

Twenty-eight semi-structured interviews were undertaken with older adults living in the community. The format of the interview enabled individuals to first tell their story, then the rainbow picture was used to further prompt discussion. Interviews were digitally recorded and transcripts were fully transcribed. Qualitative computer software package NVivo 2 was used to manage the data. Thematic analysis was undertaken.

RESULTS

Individual responsibility for health was a dominant theme although the role of health and statutory services was also recognised. Barriers to uptake of prevention activities included cultural perceptions, attitudes towards work and perceived costs of prevention activities. Participants used the rainbow for locating their personal life within a wider social, economic and policy context.

CONCLUSIONS

People view individual responsibility as key to maintaining health and draw upon the past, present and future expectations when considering social determinants of their health. The rainbow picture does have relevance at the individual level and can help to formulate more dynamic and contextualised approaches to the prevention of health conditions in community living adults.

What is self-rated health and why does it predict mortality? Towards a unified conceptual model

The association of self-rated health with mortality is well established but poorly understood. This paper provides new insights into self-rated health that help integrate information from different disciplines, both social and biological, into one unified conceptual framework. It proposes, first, a model describing the health assessment process to show how self-rated health can reflect the states of the human body and mind. Here, an analytic distinction is made between the different types of information on which people base their health assessments and the contextual frameworks in which this information is evaluated and summarized. The model helps us understand why self-ratings of health may be modified by age or culture, but still be a valid measure of health status. Second, based on the proposed model, the paper examines the association of self-rated health with mortality. The key question is, what do people know and how do they know what they know that makes self-rated health such an inclusive and universal predictor of the most absolute biological event, death. The focus is on the social and biological pathways that mediate information from the human organism to individual consciousness, thus incorporating that information into self-ratings of health. A unique source of information is provided by the bodily sensations that are directly available only to the individual him- or herself. According to recent findings in human biology, these sensations may reflect important physiological dysregulations, such as inflammatory processes. Third, the paper discusses the advantages and limitations of self-rated health as a measure of health in research and clinical practice. Future research should investigate both the logics that govern people's reasoning about their health and the physiological processes that underlie bodily feelings and sensations. Self-rated health lies at the cross-roads of culture and biology, therefore a collaborative effort between different disciplines can only improve our understanding of this key measure of health status.

Effects of child health on parents' social capital

This paper adds to the literature on social capital and health by testing whether an exogenous shock in the health of a family member (a new baby) affects the family's investment in social capital. It also contributes to a small but growing literature on the effects of children's health on family resources and provides information about associations between health and social capital in a socioeconomically disadvantaged population. We use data from the Fragile Families and Child Wellbeing study, a longitudinal survey of about 5000 births to mostly unwed parents in 20 U.S. cities during the years 1998-2000. Both parents were interviewed at the time of the birth and then again one and three years later. The infants' medical records from the birth hospitalization were reviewed, and poor infant health was characterized to reflect serious and random health problems that were present at birth. Social interactions, reported at three years, include the parents' participation in church groups, service clubs, political organizations, community groups, and organizations working with children; regular religious attendance; and visiting relatives with the child. Education, employment, wages, and sociodemographic characteristics are included in the analyses. The results suggest that infant health shocks do not affect the parents' social interactions.
