The role of pharmaceutical side-effects in depression among immigrants

OBJECTIVES

This study explores the role of pharmaceuticals with depression or suicidality as a side-effect in explaining the immigrant depression paradox. Immigrants generally report less depression than their native-born peers, despite the socio environments that are less conducive to well-being. This immigrant advantage in mental health tends to recede with time in the US and more acculturation. To date, an explanation for this pattern has remained elusive, partly because acculturation is also associated with many desirable outcomes, suggesting less depression with more acculturation.

DESIGN

Data came from seven two-year waves (2005-2006 to 2017-2018) of the National Health and Nutrition Examination Survey (NHANES). Depression was measured using the Patient Health Questionnaire (PHQ-9). Linear and logistic regressions were used to estimate the immigrant differences in depression, while controlling for sociodemographic characteristics, healthcare access, health conditions, and the use of medications with depression or suicidality as a side-effect.

RESULTS

30.3% and 22.7% of US-born adults used at least one medication with depression or suicidality as a side-effect, compared to 16.4% and 9.2% of foreign-born adults. Access to healthcare improved with time in the US and with acculturation, and both of these factors were also positively associated with the use of medications with depression or suicidality as a side-effect. The magnitude of the mediation associated with medication side-effects was significant, in many cases sufficient to eliminate the relationship between acculturation - whether expressed in terms of time in the US, English-language use, or nativity - and depression.

CONCLUSION

Exposure to medications with depression or suicidality as a side-effect helped explain part of the relative mental health advantage of foreign-born residents, as well as the diminishing advantage associated with time in the US and with acculturation.

The contingent effect of incarceration on state health outcomes

Introduction

This study examines how growth in the population of former prisoners affects rates of communicable diseases such as tuberculosis, syphilis, chlamydia, and HIV.

Methods

We estimate state-level fixed effects count models showing how the former prisoner population affected communicable disease in U.S. states from 1987 to 2010, a period of dramatic growth in incarceration.

Results

We find contingent effects, based on how specific diseases are recognized, tested, and treated in prisons. The rate of former prisoners increases diseases that are poorly addressed in the prison health care system (e.g., chlamydia), but decreases diseases that are routinely tested and treated (e.g., tuberculosis). For HIV, the relationship has shifted in response to specific treatment mandates and protocols. Data on prison healthcare spending tracks these contingencies.

Discussion

Improving the health of prisoners can improve the health of the communities to which they return. We consider these results in light of the relative quality of detection and treatment available to underserved populations within and outside prisons.

Pharmaceutical Side Effects and the Sex Differences in Depression and Distress

INTRODUCTION

Women suffer from depression at higher rates than men. This difference is well established, although a consolidated explanation remains elusive. This study examines the role played by medications with depression or suicidality as a potential side effect in explaining the sex difference in depression.

METHODS

Data were analyzed for 224,810 U.S. adults aged ≥18 years from the 2008-2018 Medical Expenditure Panel Survey. Linear and logistic regressions were used to assess the sex differences in distress and depression while controlling for sociodemographic characteristics, healthcare access, health conditions, and the use of medications with depression or suicidality as a side effect.

RESULTS

41% and 28% of women used ≥1 medication with depression and suicidality as a side effect compared with 27% and 17% of men, respectively. When controlling for sociodemographic characteristics, healthcare access, and health conditions, women were more likely to report significant distress (OR=1.16, 95% CI=1.10, 1.24) and major depression (OR=1.12, 95% CI=1.07, 1.18) than men. In models that further adjusted for the use of medications with depression or suicidality as a side effect, the sex differences became statistically nonsignificant for both distress (OR=0.97, 95% CI=0.91, 1.03) and depression (OR=0.97, 95% CI=0.92, 1.02). Nonhormone medications (rather than hormone medications) with such side effects helped explain the sex differences in distress and depression.

CONCLUSIONS

Findings suggest a significant sex difference in pharmaceutical treatment and the potential consequences of pharmaceutical side effects on distress and depression. These results highlight the importance of pharmaceutical side effects in understanding health and health disparities.

The Nexus of Physical and Psychological Pain: Consequences for Mortality and Implications for Medical Sociology

Although physical pain lies at the intersection of biology and social conditions, a sociology of pain is still in its infancy. We seek to show how physical and psychological pain are jointly parts of a common expression of despair, particularly in relation to mortality. Using the 2002-2014 National Health Interview Survey Linked Mortality Files (N = 228,098), we explore sociodemographic differences in the intersection of physical and psychological pain (referred to as the "pain-distress nexus") and its relationship to mortality among adults ages 25 to 64. Results from regression and event history models reveal that differences are large for the combination of the two, pointing to an overlooked aspect of health disparities. The combination of both high distress and high pain is most prevalent and most strongly predictive of mortality among socioeconomically disadvantaged, non-Hispanic whites. These patterns have several implications that medical sociology is well positioned to address.

The impact of disease-related knowledge on perceptions of stigma among patients with Hepatitis C Virus (HCV) infection

Most patients with hepatitis C virus (HCV) infection perceive some degree of disease-related stigma. Misunderstandings about diseases may contribute to disease-related stigma. The objective of this study was to evaluate patient-level knowledge about HCV infection transmission and natural history and its association with HCV-related stigma among HCV-infected patients. We conducted a cross-sectional survey study among 265 patients with HCV in Philadelphia using the HCV Stigma Scale and the National Health and Nutrition Examination Survey (NHANES) Hepatitis C Follow-up Survey (2001-2008). The association between HCV knowledge and HCV-related stigma was evaluated via linear regression. Overall knowledge about HCV transmission and natural history was high, with >80% of participants answering ≥9 of 11 items correctly (median number of correct responses, 9 [82%]), HCV-related knowledge was similar between HIV/HCV-coinfected and HCV-monoinfected participants (p = 0.30). A higher level of HCV-related knowledge was associated with greater perceived HCV-related stigma (β, 2.34 ([95% CI, 0.51-4.17]; p = 0.013). Results were similar after adjusting for age, race, ethnicity, HIV status, education level, stage of HCV management, time since diagnosis, and history of injection drug use. In this study, increased HCV-related knowledge was associated with greater perceptions of HCV stigma. Clinicians may consider allotting time to address common misconceptions about HCV when educating patients about HCV infection, which may counterbalance the stigmatizing impact of greater HCV-related knowledge.

1072. The Impact of Hepatitis C-Related Knowledge on Perceptions of Stigma Among Infected Individuals

Background

Stigma is an important and understudied barrier to hepatitis C virus (HCV) infection treatment and elimination. Education to dispel disease-based myths and misinformation has been identified as a key intervention point to reduce disease-related stigma; however, the association between knowledge about HCV infection and perceptions of stigma among HCV-infected patients remains unknown.

Methods

To address this gap and evaluate the association between patient-level HCV knowledge and HCV-related stigma, we conducted a cross-sectional study among 270 HCV-infected patients (147 [56%] HIV-coinfected) from 5 clinics across Philadelphia. HCV-related stigma was measured using the validated 33-item HCV Stigma Scale (range, 33-132). HCV-related knowledge was measured via the National Health and Nutrition Examination Survey (NHANES) Hepatitis C Follow-up Survey (2003-2008), an eleven item True/False survey (range, 0 to 11) comprising statements about HCV-related health effects and transmission. The association between HCV knowledge and HCV-related stigma was evaluated via linear regression by HIV status. Self-reported demographic, behavioral, and clinical covariates were evaluated in adjusted analyses.

Results

The median overall HCV knowledge score was high at 9 out of 11 points (IQR, 9-10). Median knowledge scores did not significantly differ between HIV/HCV-coinfected and HCV-monoinfected participants (10 versus 9; p=0.29). However, higher HCV knowledge scores were associated with higher HCV-related stigma score among HCV-monoinfected participants (p=0.03) but not among HCV/HIV-coinfected participants (p=0.12). Differences by HIV status were also observed when adjusting for demographic, behavioral, and clinical covariates.

Conclusion

Regardless of HIV status, the majority of both HIV/HCV-coinfected and HCV-monoinfected participants in this study answered questions about HCV knowledge correctly. Surprisingly, greater HCV knowledge was associated with increased HCV-related stigma among HCV-monoinfected participants, but this association was not observed among coinfected participants. Additional studies are needed to understand why this association was observed only among monoinfected persons.

HFE and ALK3 act in the same signaling pathway

Hepcidin deficiency leads to iron overload by increased dietary iron uptake and iron release from storage cells. The most frequent mutation in Hfe leads to reduced hepcidin expression and thereby causes iron overload. Recent findings suggested that HFE activates hepcidin expression predominantly via the BMP type I receptor ALK3. Here, we investigated whether HFE exclusively utilizes ALK3 or other signaling mechanisms also. We generated mice with double deficiency of Hfe and hepatocyte-specific Alk3 and compared the iron overload phenotypes of these double knockout mice to single hepatocyte-specific Alk3 deficient or Hfe knockout mice. Double Hfe^-/-/hepatic Alk3^fl/fl;Alb-Cre knockouts develop a similar iron overload phenotype compared to single hepatocyte-specific Alk3 deficient mice hallmarked by serum iron levels, tissue iron content and hepcidin levels of similar grades. HFE protein levels were increased in Alk3^fl/fl;Alb-Cre mice compared to Alk3^fl/fl mice, which was caused by iron overload - and not by Alk3 deficiency. The data provide evidence by genetic means that 1. HFE exclusively uses the BMP type I receptor ALK3 to induce hepcidin expression and 2. HFE protein expression is induced by iron overload, which further emphasizes the iron sensing function of HFE.

Determinants of stigma among patients with hepatitis C virus infection

Stigma around hepatitis C virus (HCV) infection is an important and understudied barrier to HCV treatment and elimination. The determinants of HCV-related stigma, including the impacts of stage of HCV treatment (ie spontaneously cleared; diagnosed, untreated; previously treated, not cured; currently being treated; and treated, cured) and coinfection with human immunodeficiency virus (HIV), remain unknown. To address these gaps, we conducted a cross-sectional study among patients with a history of HCV infection (n = 270) at outpatient clinics in Philadelphia from July 2018 to May 2019. We evaluated stigma using the validated HCV Stigma Scale, adapted from the Berger HIV Stigma Scale. Associations among HCV-related stigma and hypothesized demographic, behavioural, and clinical risk factors were evaluated by multivariable linear regression. Most participants (95.5%) experienced HCV-related stigma. Mean stigma scores did not differ significantly between HCV-monoinfected and HIV/HCV-coinfected participants (P = .574). However, we observed significant interactions between HIV status and multiple determinants; therefore, we stratified analyses by HIV status. Among HIV/HCV-coinfected participants, previous HCV treatment without cure, female gender, Hispanic/Latinx ethnicity and some college education were significantly associated with higher HCV-stigma scores. An annual income of $10 000-$40 000 was associated with significantly lower stigma scores. No significant associations were observed among HCV-monoinfected participants. We found that most participants experienced stigma associated with HCV diagnosis. While stigma scores were similar between HCV-monoinfected and HIV/HCV-coinfected participants, the determinants associated with HCV stigma differed by HIV status. Understanding how experiences of stigma differ between HCV-monoinfected and HIV/HCV-coinfected patients may aid in the development of targeted interventions to address the HCV epidemic.

Neither mad nor bad? The classification of antisocial personality disorder among formerly incarcerated adults

Using the National Comorbidity Survey, this study explores the presence and symptoms of antisocial personality disorder (ASPD) among people with varying degrees of contact with the criminal justice system. The study finds an elevated prevalence of ASPD among formerly incarcerated persons, but also that ASPD is not a simple linear function of actual or potential contact with the criminal justice system. For example, among people who have been arrested the prevalence of ASPD is not much greater than among those who committed a crime but were never arrested. Furthermore, the difference in prevalence between those who were incarcerated and those who were arrested but not incarcerated is small. Moreover, the prevalence is highly sensitive to the elimination of one particular symptom among seven: failure to conform to social norms, as indicated by having been arrested. Eliminating this single symptom reduces the prevalence of ASPD by more than 50%, even among formerly incarcerated persons. Additional analyses reveal that, among formerly incarcerated persons who meet the diagnostic threshold for ASPD, their set of symptoms is perhaps driven more by their circumstance than their personality. For example, while formerly incarcerated persons frequently report failing to fulfill their promises, fewer than one in ten report a lack of remorse for having mistreated others. These findings suggest the need to further contextualize ASPD symptomatology, particularly among populations with frequent contact with the criminal justice system.

In-utero determinants of adult depression: evidence from the 1918 flu pandemic

Social scientists have dealt only glancing with potential in-utero determinants of mental health. This study looks at the enduring consequences of gestational exposure to the 1918 flu pandemic for adult depression. It does so using data collected in the first wave of the National Health and Nutrition Examination Survey (1971-1975), corresponding to when those exposed in-utero were in their early to mid-50s. The results indicate very strong effects of in-utero exposure on depression. These effects are only found, however, among men. The effects are sufficiently large to eliminate sex differences in major depression within a cohort: among those born in 1919, the prevalence of major depression is about 1 in 5 for both men and women. Additional analyses further clarify the relationship, showing effects of in-utero exposure across the full spectrum and syndrome of depressive symptoms. In addition, the effects are stronger for symptoms related to depression than for symptoms related to schizophrenia. Additional analyses show that the effect of exposure is reduced somewhat when adjusting for later socioeconomic disadvantages. In addition, the effect is reduced when controlling for broader dimensions of physical health. Yet neither of these relationships explains the effects of exposure altogether.

Pharmaceutical Side Effects and Mental Health Paradoxes among Racial-Ethnic Minorities

Sociologists have long struggled to explain the minority mental health paradox: that racial-ethnic minorities often report better mental health than non-Hispanic whites despite social environments that seem less conducive to well-being. Using data from the 2008-2013 Medical Expenditure Panel Survey (MEPS), this study provides a partial explanation for the paradox rooted in a very different disparity. Evidence from MEPS indicates that non-Hispanic whites consume more pharmaceuticals than racial-ethnic minorities for a wide variety of medical conditions. Moreover, non-Hispanic whites consume more pharmaceuticals that although effective in treating their focal indication, include depression or suicide as a side effect. In models that adjust for the use of such medications, the minority advantage in significant distress is reduced, in some instances to statistical nonsignificance. Although a significant black and Hispanic advantage in a continuous measure of distress remains, the magnitude of the difference is reduced considerably. The relationship between the use of medications with suicide as a side effect and significant distress is especially large, exceeding, for instance, the relationship between poverty and significant distress. For some minority groups, the less frequent use of such medications is driven by better health (as in the case of Asians), whereas for others, it reflects a treatment disparity (as in the case of blacks), although the consequences for the mental health paradox are the same. The implications of the results are discussed, especially with respect to the neglect of psychological side effects in the treatment of physical disease as well as the problem of multiple morbidities.

Validation of a modified Berger HIV stigma scale for use among patients with hepatitis C virus (HCV) infection

BACKGROUND

Stigma around hepatitis C virus (HCV) infection is an important and understudied barrier to HCV prevention, treatment, and elimination. To date, no validated instrument exists to measure patients' experiences of HCV stigma. This study aimed to revise the Berger (2001) HIV stigma scale and evaluate its psychometric properties among patients with HCV infection.

METHODS

The Berger HIV stigma scale was revised to ask about HCV and administered to patients with HCV (n = 270) in Philadelphia, Pennsylvania. Scale reliability was evaluated as internal consistency by calculating Cronbach's alpha. Exploratory factor analysis was performed to evaluate construct validity by comparing item clustering to the Berger HIV stigma scale subscales. Item response theory was employed to further evaluate individual items and to calibrate items for simulated computer adaptive testing sessions in order to identify potential shortened instruments.

RESULTS

The revised HCV Stigma Scale was found to have good reliability (α = 0.957). After excluding items for low loadings, the exploratory factor analysis indicated good construct validity with 85% of items loading on pre-defined factors. Analyses strongly suggested the predominance of an underlying unidimensional factor solution, which yielded a 33-item scale after items were removed for low loading and differential item functioning. Adaptive simulations indicated that the scale could be substantially shortened without detectable information loss.

CONCLUSIONS

The 33-item HCV Stigma Scale showed sufficient reliability and construct validity. We also conducted computer adaptive testing simulations and identified shortened six- and three-item scale alternatives that performed comparably to the original 40-item scale.

Utilization of Medications With Cognitive Impairment Side Effects and the Implications for Older Adults' Cognitive Function

Objectives: Many medications have cognitive impairment, memory loss, amnesia, or dementia as side effects ("cognitive side effects" hereafter), but little is known about trends in the prevalence of these medications or their implications for population-level cognitive impairment. Method: We use data from the National Health and Nutrition Examination Survey (1999-2016) to describe trends in the use of medications with cognitive side effects among adults aged 60+ (N = 16,937) and their implications for cognitive functioning (measured using word learning and recall, animal fluency, and digit symbol substitution assessments). Results: Between 1999 to 2000 and 2015 to 2016, the prevalence of older adults taking one, two, and at least three medications with cognitive side effects increased by 10.2%, 57.3%, and 298.7%, respectively. Compared to non-users, respondents who simultaneously used three or more medications with cognitive side effects scored 0.22 to 0.27 standard deviations lower in word learning and recall (p = .02), digit symbol substitution (p < .01), and the average standardized score of the three assessments (p < .001). Limitation: Dosage of medications associated with cognitive side effects was not measured. Discussion: Concurrent use of medications with cognitive side effects among older adults has increased dramatically over the past two decades. The use of such medications is associated with cognitive impairment and may explain for disparities in cognitive function across subgroups. These findings highlight the need for cognitive screenings among patients who consume medications with cognitive side effects. They also highlight the synergic effects of polypharmacy and potential drug-drug interactions that result in cognitive deficits.

Religion, social integration, and depression in Europe: Evidence from the European Social Survey

Western Europe's growing Muslim population has occasioned considerable debate regarding cultural integration, immigration, and social isolation. In this study I explore the relationship between religious identification and depression in European countries, focusing in particular on the situation of Muslims, but comparing across other religious groups, as well as those who are unaffiliated with any religion. The analysis is based on countries sampled in the sixth round of the European Social Survey, conducted in 2012. The results reveal the dueling effects of religious identity: religious involvement involves social integration among like-minded friends, but can also invite discrimination from others. This dueling effect implies significant differences between groups. Among Protestants and Catholics greater religious identification is associated with progressively lower depression, relative to those with no affiliation. Among Muslims lower levels of identification are associated with significantly more depression. Muslims of the highest level of identification are statistically indistinguishable from those with no religious affiliation. These patterns among Muslims are not born of poor social integration, but rather reflect more experiences with discrimination. Overall differences among religious groups are very strong: the difference in depression between Muslims and Protestants, for instance, exceeds the difference between men and women.

Season of birth and depression in adulthood: Revisiting historical forerunner evidence for in-utero effects

Evidence showing a relationship between season of birth and adult well-being is long-standing, but is now largely overlooked or dismissed. In light of increasingly compelling evidence for the effects of in-utero conditions on adult health, however, it is instructive to revisit the relationship, with an eye toward resolving the reasons for skepticism. This study uses data from the first National Health and Nutritional Examination Survey to examine the effects of month of birth on adult depression. The data correspond to an important time in history and the analysis points to one reason why enthusiasm for birth seasonality in depression has faded: although there was a strong relationship between month of birth and depression in the early 20th century, with spring and summer month births corresponding to significantly more depression, the relationship was largely eliminated by the 1940 birth cohort. Few adults alive today would be subject to this effect, but when it was apparent it was enormously consequential. Population attributable risk scenarios indicate that among those born between 1900 and 1920 the prevalence of major depression would have been reduced by approximately 22% if all births had been confined to November through March. The percent rises to 26% among those born between 1900 and 1910, and was likely even higher in earlier cohorts. Additional analyses point to the importance of nutritional deficits in explaining these effects. In the early 20th century, the relationship between month of birth and depression was weaker in circumstances where the food supply was less seasonally sensitive. For this reason, the turn-of-the-century relationship between month of birth and depression was much weaker among the well-educated, in Southern states, and in urban areas. Although birth seasonality in depression can be regarded as a historical artefact of diet and nutrition, evidence for its prior existence nonetheless speaks to the significance of other in-utero effects, both past and present.

The Growth, Scope, and Spatial Distribution of People With Felony Records in the United States, 1948-2010

The steep rise in U.S. criminal punishment in recent decades has spurred scholarship on the collateral consequences of imprisonment for individuals, families, and communities. Several excellent studies have estimated the number of people who have been incarcerated and the collateral consequences they face, but far less is known about the size and scope of the total U.S. population with felony convictions beyond prison walls, including those who serve their sentences on probation or in jail. This article develops state-level estimates based on demographic life tables and extends previous national estimates of the number of people with felony convictions to 2010. We estimate that 3 % of the total U.S. adult population and 15 % of the African American adult male population has ever been to prison; people with felony convictions account for 8 % of all adults and 33 % of the African American adult male population. We discuss the far-reaching consequences of the spatial concentration and immense growth of these groups since 1980.

Social Distance in the Clinical Encounter: Interactional and Sociodemographic Foundations for Mistrust in Physicians

Although many observers have drawn attention to the low levels of trust in physicians among members of racial/ethnic minorities and those of lower socioeconomic status, the reasons for this mistrust are not well understood. Using a social distance perspective and a large, nationally representative data set, I find that blacks and Hispanics are less trusting of their personal physicians than are whites and that education and income both increase physician trust. A fraction of each of these differences can be explained by physicians' behavior (the perceived thoroughness of the last examination, how well the physician listened, and how well the physician explained), but most of each difference remains well after physicians' behavior is held constant. The otherwise positive, strong effect of physicians' behavior has only a limited capacity to explain these differences because social distance moderates the strength of the effect of that behavior. For blacks, Hispanics, and those of lower socioeconomic status, physicians' behavior exerts much less effect on trust than for whites and those of higher socioeconomic status. A social distance perspective helps to explain this downweighting, as well as the divergent ways in which different sociodemographic groups evaluate physicians. By understanding the inference of trust as a social cognitive process, scholars can understand more clearly why some groups are more receptive to physicians than others, and why some groups' mistrust is more resistant to updating.

The Institutional Effects of Incarceration: Spillovers From Criminal Justice to Health Care

POLICY POINTS

The steady increase in incarceration is related to the quality and functioning of the health care system. US states that incarcerate a larger number of people show declines in overall access to and quality of care, rooted in high levels of uninsurance and relatively poor health of former inmates. Providing health care to former inmates would ease the difficulties of inmates and their families. It might also prevent broader adverse spillovers to the health care system. The health care system and the criminal justice system are related in real but underappreciated ways.

CONTEXT

This study examines the spillover effects of growth in state-level incarceration rates on the functioning and quality of the US health care system.

METHODS

Our multilevel approach first explored cross-sectional individual-level data on health care behavior merged to aggregate state-level data regarding incarceration. We then conducted an entirely aggregate-level analysis to address between-state heterogeneity and trends over time in health care access and utilization.

FINDINGS

We found that individuals residing in states with a larger number of former prison inmates have diminished access to care, less access to specialists, less trust in physicians, and less satisfaction with the care they receive. These spillover effects are deep in that they affect even those least likely to be personally affected by incarceration, including the insured, those over 50, women, non-Hispanic whites, and those with incomes far exceeding the federal poverty threshold. These patterns likely reflect the burden of uncompensated care among former inmates, who have both a greater than average need for care and higher than average levels of uninsurance. State-level analyses solidify these claims. Increases in the number of former inmates are associated simultaneously with increases in the percentage of uninsured within a state and increases in emergency room use per capita, both net of controls for between-state heterogeneity.

CONCLUSIONS

Our analyses establish an intersection between systems of care and corrections, linked by inadequate financial and administrative mechanisms for delivering services to former inmates.

Cultural reflexivity in health research and practice

Recent public health movements have invoked cultural change to improve health and reduce health disparities. We argue that these cultural discourses have sometimes justified and maintained health inequalities when those with power and authority designated their own social practices as legitimate and healthy while labeling the practices of marginalized groups as illegitimate or unhealthy. This "misrecognition," which creates seemingly objective knowledge without understanding historical and social conditions, sustains unequal power dynamics and obscures the fact that what is deemed legitimate and healthy can be temporally, geographically, and socially relative. We use examples from research across multiple disciplines to illustrate the potential consequences of cultural misrecognition, highlight instances in which culture was invoked in ways that overcame misrecognition, and discuss how cultural reflexivity can be used to improve health research and practice.

The relationship between incarceration and premature adult mortality: gender specific evidence

We examine the relationship between incarceration and premature mortality for men and women. Analyses using the National Longitudinal Survey of Youth (NLSY79) reveal strong gender differences. Using two different analytic procedures the results show that women with a history of incarceration are more likely to die than women without such a history, even after controlling for health status and criminal behavior prior to incarceration, the availability of health insurance, and other socio-demographic factors. In contrast, there is no relationship between incarceration and mortality for men after accounting for these factors. The results point to the importance of examining gender differences in the collateral consequences of incarceration. The results also contribute to a rapidly emerging literature linking incarceration to various health hazards. Although men constitute the bulk of inmates, future research should not neglect the special circumstances of female former inmates and their rapidly growing numbers.

The increasing predictive validity of self-rated health

Using the 1980 to 2002 General Social Survey, a repeated cross-sectional study that has been linked to the National Death Index through 2008, this study examines the changing relationship between self-rated health and mortality. Research has established that self-rated health has exceptional predictive validity with respect to mortality, but this validity may be deteriorating in light of the rapid medicalization of seemingly superficial conditions and increasingly high expectations for good health. Yet the current study shows the validity of self-rated health is increasing over time. Individuals are apparently better at assessing their health in 2002 than they were in 1980 and, for this reason, the relationship between self-rated health and mortality is considerably stronger across all levels of self-rated health. Several potential mechanisms for this increase are explored. More schooling and more cognitive ability increase the predictive validity of self-rated health, but neither of these influences explains the growing association between self-rated health and mortality. The association is also invariant to changing causes of death, including a decline in accidental deaths, which are, by definition, unanticipated by the individual. Using data from the final two waves of data, we find suggestive evidence that exposure to more health information is the driving force, but we also show that the source of information is very important. For example, the relationship between self-rated health and mortality is smaller among those who use the internet to find health information than among those who do not.

As fathers and felons: explaining the effects of current and recent incarceration on major depression

Dramatic increases in the American imprisonment rate since the mid-1970s have important implications for the life chances of minority men with low educational attainment, including for their health. Although a large literature has considered the collateral consequences of incarceration for a variety of outcomes, studies concerned with health have several limitations: Most focus exclusively on physical health; those concerned with mental health only consider current incarceration or previous incarceration, but never both; some are cross-sectional; many fail to consider mechanisms; and virtually all neglect the role of family processes, thereby overlooking the social roles current and former prisoners inhabit. In this article, we use stress process theory to extend this research by first considering the association between incarceration and major depression and then considering potential mechanisms that explain this association. Results from the Fragile Families and Child Wellbeing Study (N = 3,107) show current and recent incarceration are substantially associated with the risk of major depression, suggesting both immediate and short-term implications. In addition, consistent with stress proliferation theory, the results show the well-known consequences of incarceration for socioeconomic status and family functioning partly explain these associations, suggesting the link between incarceration and depression depends heavily on the consequences of incarceration for economic and social reintegration, not only the direct psychological consequences of confinement.

Learning to do well or learning to do good? Estimating the effects of schooling on civic engagement, social cohesion, and labor market outcomes in the presence of endowments

Although some point to the large effects of schooling on civic engagement (usually measured in terms of volunteering and participation in civic organizations) and social cohesion (usually measured in terms of social networks and relationship quality), the effects of schooling on social outcomes have not been estimated with the same rigor as the effects of schooling on labor-market outcomes, such as earnings. In particular, previous research has failed to consider (i) the many potential and often unobserved confounding factors ("endowments") influencing both schooling and social outcomes, including family upbringing, innate characteristics, and personality, and (ii) the ways in which schooling pushes individuals in multiple directions simultaneously, including toward greater social engagement, but also toward more independent and market-driven pursuits. Using samples of unrelated persons, ordinary siblings, and identical twins, this study explores the effects of schooling on measures of civic engagement and social relationships, as well as labor-force earnings and labor-force participation. The siblings models reveal a more complex picture than typically suggested by standard individual estimates. On one hand, the results reveal a robust positive effect of schooling on earnings: well-schooled persons work more and earn more, albeit not as much as associations without control for endowments suggest. On the other hand, the results reveal more tenuous and occasionally negative effects of schooling on social outcomes. The effects of schooling on volunteering and membership in civic organizations, for example, disappear almost entirely with control for endowments. Also, within-identical-twins models reverse the positive effects of schooling on reports of support from friends, family, and coworkers. These results may reflect the tension schooling creates between market and non-market commitments, as well as between independence and interpersonal reliability. Schooling may, indeed, induce some pro-social behaviors, but schooling allows individuals choices of whether to pursue more personal interests as well.

Social science methods for twins data: integrating causality, endowments, and heritability

Twins have been extensively used in economics, sociology, and behavioral genetics to investigate the role of genetic endowments on a broad range of social, demographic, and economic outcomes. However, the focus in these literatures has been distinct.: The economic literature has been primarily concerned with the need to control for unobserved endowments--including as an important subset, genetic endowments--in analyses that attempt to establish the impact of one variable, often schooling, on a variety of economic, demographic, and health outcomes. Behavioral genetic analyses have mostly been concerned with decomposing the variation in the outcomes of interest into genetic, shared environmental, and non-shared environmental components, with recent multivariate analyses investigating the contributions of genes and the environment to the correlation and causation between variables. Despite the fact that twins studies and the recognition of the role of endowments are central to both of these literatures, they have mostly evolved independently. In this paper we develop formally the relationship between the economic and behavioral genetic approaches to the analyses of twins, and we develop an integrative approach that combines the identification of causal effects, which dominates the economic literature, with the decomposition of variances and covariances into genetic and environmental factors that are the primary goal of behavioral genetic approaches. We apply this integrative ACE-beta approach to an illustrative investigation of the impact of schooling on several demographic outcomes such as fertility and nuptiality and health.

Gene-environment correlations in the stress-depression relationship

A critical feature of the social stress model is the apparent relationship between stress and depression. Although many studies have demonstrated a connection between the two, the relationship may be contaminated by genes affecting both stress and depression. Using a sample of identical and fraternal twins, this study explores genetic influences on depression and assorted sources of stress while explicitly estimating, and thereby controlling for, gene-environment correlations. I consider both stress and depression in a fine-grained fashion. For the former, the study explores assorted sources of stress, including health and disability, family, unemployment, discrimination, and perceived neighborhood safety, as gene-environment correlations may be stronger for some forms of stress than others. For the latter, the study explores both depressive symptoms and major depressive disorders, as each may entail a different epidemiological process, especially with respect to genes. The results reveal that most, but not all, measures of stress have moderate heritabilities, suggesting that genes influence exposure to the environment in a broad fashion. Yet, despite this, the relationship between stress and depression is generally robust to gene-environment correlations. There are some notable exceptions. For example, allowing for gene-environment correlations, marital conflict is generally unrelated to depression. Moreover, gene-environment correlations are generally stronger for major depression than for depressive symptoms, encouraging further elaboration of the distinction between the onset of depression and its recurrence, especially in the context of genes. These exceptions do not put limits on environmental influence, but do suggest that genes operate in a complex life-course fashion.

Methuselah's medicine: pharmaceutical innovation and mortality in the United States, 1960-2000

Although there is a good deal of speculation surrounding the role of pharmaceutical innovation in late 20th century mortality improvements in the United States, there is little empirical evidence on the topic and there remains a good deal of doubt regarding whether pharmaceuticals matter at all for mortality. Using a reliable indicator of pharmaceutical innovation-yearly approvals of new molecular entities (NMEs) by the Food and Drug Administration, along with information on priority status and disease-category indication-this study examines the relationship between pharmaceutical innovation and life expectancy between 1960 and 2000. The study demonstrates a significant relationship between pharmaceutical innovation and life expectancy at birth, which is robust to controls for gross domestic product, as well as controls for various forms of medical spending. The relationship with life expectancy is robust, in part, because pharmaceutical innovation has a stronger relationship with early-life mortality (between 20 and 50) than with later-life mortality (65 and over), even though older persons consume more pharmaceuticals and many recently approved drugs target conditions more common in later life. There is, to be sure, another side to the results. There is some evidence, for example, that the relationship between pharmaceutical innovation and mortality has declined over time, suggesting a change in the kind of innovations now entering the market. Nevertheless, there is more to contemporary pharmaceutical innovation than the development of mere "halfway" technologies. The overall relationship between innovation and mortality is sufficiently strong to warrant further consideration as a key determinant of trends in mortality.

The role of income and race/ethnicity in experiences with medical care in the United States and United Kingdom

Inequalities in experiences with medical care are well-known in the United States, but little is known about the shape of such inequalities in other countries. This study compares a broad spectrum of experiences in the United States and United Kingdom. Furthermore, it focuses on two of the most important dimensions of inequality, race/ethnicity and income, and two of the most widely discussed system-level factors, health insurance and emphasis on primary care. Two general conclusions are reached. First, there are broad income-based inequalities in medical care in both the United States and United Kingdom. These inequalities persist even after controlling for health insurance, including private medical insurance in the United Kingdom. Race is also related to experiences with medical care, although the effects of race are more particular and contingent than are those for income. In particular, the mapping of racial/ethnic inequality differs considerably between the United States and United Kingdom, reflecting their different sociocultural climates. Second, the health care system, especially primary care, plays a limited role in ameliorating inequalities in care, but plays a strong role in elevating the average level of quality within a country. Because inequalities in medical care reflect broader social processes, they are durable across very different health care systems and contexts.

Happiness and success: genes, families, and the psychological effects of socioeconomic position and social support

Although there is considerable evidence linking success -- including wealth, marriage, and friendships -- to happiness, this relationship might not reflect, as is often assumed, the effects of the proximate environment on well-being. Such an interpretation is contravened by evidence that both happiness and the environment are influenced by genetic factors and family upbringing. Using the National Survey of Midlife Development in the United States, which includes a subsample of twins, this study evaluates the relationship between happiness and various features of success before and after eliminating the influence of endowments. The results suggest that many putative indicators of the environment are highly heritable and, indeed, that the same genes that affect the environment may affect happiness as well. Yet the results also suggest that the role of genetic endowments varies considerably across different features of success, suggesting complex patterns of selection, reinforcement, and causation among genes and the environment.

Look (closely) at all the lonely people: age and the social psychology of social support

OBJECTIVE

This article explores the relationship between age and social support. Previous research on the relationship has reached inconsistent conclusions.

METHODS

Three theories are tested using the Americans' Changing Lives survey.

RESULTS

The likelihood of reporting no close friends or confidants increases with age, and role changes (such as the growing likelihood of living alone) account for much of this increase. Yet these cases are exceptional, and in general, the number of friends and confidants stays the same. Moreover, evaluations of support become more positive with age, and loneliness declines.

DISCUSSION

Improvements in perceived support appear to be premised on psychological processes rather than role changes: They occur despite changes in the environment and independent of how individuals make choices among friends. Indeed, this process is so powerful that loneliness declines even among those who are living alone, have no children, and report no confidants.

Enduring stigma: the long-term effects of incarceration on health

Although incarceration rates have risen sharply since the 1970s, medical sociology has largely neglected the health effects of imprisonment. Incarceration might have powerful effects on health, especially if it instills stigma, and it could provide sociologists with another mechanism for understanding health disparities. This study identifies some of incarceration's direct and indirect effects and rigorously tests them using the National Longitudinal Survey of Youth. It finds that incarceration has powerful effects on health, but only after release. A history of incarceration strongly increases the likelihood of severe health limitations. Furthermore, any contact with prison is generally more important than the amount of contact, a finding consistent with a stigma-based interpretation. Although this relationship is partly attributable to diminished wage growth and marital instability, the bulk of the effect remains even under the most stringent of specifications, including controls for intelligence and the use of fixed effects, suggesting a far-reaching process with a proliferation of risk factors. The study also finds that incarceration contributes only modestly to racial disparities, that there are few synergistic interactions between incarceration and other features of inequality, including schooling, and that the evidence for a causal effect is much weaker among persistent recidivists and those serving exceptionally long sentences. These study findings are inconsistent with recent speculation; nevertheless, incarceration is an important addition to sociology's research agenda. Exploring incarceration could lead to, among other things, a fruitful synergy among studies on fundamental causes, stigma, and stress.

Psychological factors as mechanisms for socioeconomic disparities in health: a critical appraisal of four common factors

Social epidemiology has increasingly looked to psychological factors as both risk factors for physical health and mechanisms behind disparities. Yet, there has been little resolution to the question of whether psychological factors explain disparities, and skepticism has begun to mount about whether psychological factors are causally linked to health. Furthermore, some have questioned the nature of the relationship: most research suggests that psychological factors mediate the relationship between socioeconomic status and health, but recent research suggests that they moderate the relationship. The present paper attempts to provide a more comprehensive appraisal of the current debate. It uses four popular psychological factors (i.e., self-esteem, mastery, neuroticism, and depressive symptoms), three health outcomes, and a nationally representative, three-panel longitudinal survey. The results illustrate the promise and limitations of psychological mechanisms. In the cross-section, the results provide evidence for substantial moderating effects, but these effects disappear entirely when estimated prospectively. The results also provide some evidence for mediating effects, but these effects are very weak and the prospective effects of psychological factors diminish over time and with controls for baseline health. Implications for theories of socioeconomic status and health are discussed and a more social psychologically sophisticated approach is encouraged.

The promise and limits of racial/ethnic concordance in physician-patient interaction

Although some scholars suggest that racial/ethnic concordance between physicians and patients will do much to eliminate disparities in medical care, the evidence for concordance effects is mixed. Using nationally representative data with an oversample of blacks and Latinos, this study examines a variety of topics, including beliefs about and preferences for concordance, the effects of concordance on patient experiences, and interactions between expectations and experiences. The results point to the limited effects of concordance in general but illuminate for whom concordance matters most. The results encourage more nuanced and contingent theories. They suggest that racial/ethnic concordance holds little salience in the minds of most black and Latino patients and that discordance has little effect. Nevertheless, there is some evidence that concordance has a positive effect among those who prefer concordance-thus the apparent effects of concordance might reflect the effects of patient choice more than concordance per se. The conclusion sketches policy implications, including the merits of promoting concordance among targeted groups of patients, even in the absence of overall effects on disparities.

When mental health becomes health: age and the shifting meaning of self-evaluations of general health

Do self-evaluations of general health change as individuals age? Although several perspectives point to age-related shifts, few researchers have compared them. For this article, several competing hypotheses were tested using a large, nationally representative, and longitudinal data set. The results suggest two trends. First, the correspondence between functional limitations and self-rated health declines, especially after age 50. Similarly, the correspondence between various chronic conditions and self-rated health declines with age. These findings are consistent with social comparison theory. Yet, the results also suggest that the correspondence between depressive symptoms and self-rated health increases. Indeed, after age 74, the correspondence between self-rated health and some common symptoms of depression becomes stronger than that between self-rated health and several chronic, and often fatal, somatic conditions. This crossover has important implications for the detection and treatment of depressive symptoms in later life.

Chronic illness and depressive symptoms in late life

The relationship between illness and depressive symptoms is examined using a large, nationally representative, and longitudinal sample of Americans over the age of 50. Seven illnesses (cancer, stroke, heart condition, chronic obstructed pulmonary disease, diabetes, high blood pressure, and arthritis) and three forms of disability (activities in daily living, mobility, and strength) substantially increase symptoms. Yet, most of these positive effects diminish with age. Multiplicative interactions between age and illness indicate that those who develop chronic illnesses earlier in life tend to report more depressive symptoms than do those who develop them later. Similarly, disability leads to more depressive symptoms when experienced at younger ages. This age-graded effect emerges even for illnesses that are known to share a biological substrate with depression (e.g. vascular disorders). The results are discussed with respect to theories of illness, depression, and aging.

Education and the changing shape of the income gradient in health

Research on the social determinants of health has increasingly sought to understand the relative importance of different features of socioeconomic status. Much of the ensuing debate has wavered between education and income, with recent research leaning increasingly toward income. This research has not, however, consistently explored interactions between different features of socioeconomic status and, in trying to understand the independent effects of different components of socioeconomic status, may have missed important features of socioeconomic position. With an eye toward examining how features of socioeconomic status combine and coalesce, this paper examines variation in the income-health association by level of education. Theories derived both from medical sociology and health economics suggest synergistic interactions between income and education, but they are unclear as to the direction and magnitude of these interactions. Results from two large and nationally representative data sets (the 1996-1997 Community Tracking Study and the 1972-2000 General Social Survey) indicate that the positive relationship between income and health varies substantially in both its strength and shape by level of education. Education improves health, and its effects are larger at lower levels of income. Moreover, education reduces the strength and curvature of the income-health relationship. Consequently, those with more education have better health for all levels of income, and fewer income-based disparities exist among the well educated than among the less well educated. The linear "gradient" relationship between income and health is, thus, more characteristic of groups with higher levels of education. Additional analyses indicate that these interactions existed in the United States in each of the last three decades. The results are discussed in light of theory regarding the perpetuation of health disparities, as well as current debates regarding the apparent incompatibility of distributive versus aggregative goals in health policy.

Misgivings of medicine?: African Americans' skepticism of psychiatric medication

Research has consistently documented black-white differences in rates of voluntary psychiatric treatment that cannot be reduced entirely to differences in either need or access. A variety of explanations have been offered for the gap that remains, but the empirical testing of alternative propositions has thus far been minimal. Using the 1998 General Social Survey's Pressing Issues in Health and Medical Care module (n = 1,387), I find consistent and substantial black-white differences in a variety of beliefs about psychiatric medications, one of the most common treatments for mental illness, and the predisposition to use them. Specifically, blacks express less willingness to use psychiatric medications themselves or to administer them to a child for whom they are responsible. Neither socioeconomic status, knowledge, religious involvement, nor trust in medicine appears to explain this reluctance. Rather, it stems almost entirely from blacks' beliefs about psychiatric medications' efficacy and side-effects. The results indicate, first, that researchers should not assume that African Americans will use psychiatric medications at rates similar to whites if offered equal access. Second, the results indicate that blacks' skepticism of psychiatric medications may be rooted in specific beliefs about psychiatric medications, rather than general ideologies about medical practice. Health beliefs about psychiatric treatment, therefore, will continue to play an important role in understanding race differences in the use of psychiatric medications.

American attitudes toward and willingness to use psychiatric medications

Despite recent advances in treatment, many Americans decline to take prescribed psychiatric medication. This study explores the role of attitudes regarding the effectiveness of and potential problems associated with psychiatric medications on Americans' willingness to use them. Face-to-face interviews of a US household population sample were done with 1387 volunteers. The 1998 General Social Survey's (response rate, 76.4%) included questions about efficacy, problems, and potential use. Most Americans agree that psychiatric medications are effective, and fewer than half had concerns regarding potential problems. However, the majority of respondents would not be willing to take them. Willingness to use is influenced by these attitudes and other factors, including health status and past use of mental health treatments. Although Americans perceive psychiatric medications to be effective, and this influences their willingness to take them, many still are not willing to take them.

Injuries to the nervous system and spine in downhill skiing

The authors describe injuries to the nervous system and spine from downhill skiing accidents through a review of the charts of downhill skiers admitted over 5 years to the three teaching hospitals of the University of Calgary. The office of the chief medical examiner provided details about accidental deaths from downhill skiing in which nervous system trauma occurred. During the study period, 145 downhill skiers suffered injury to the nervous system or spine. There were five deaths from nervous system trauma. The mean age of the injured skiers was 23.8 years, and these injuries were three times more common in men than in women. Eighty-eight skiers sustained a head injury, 25 had spinal fractures alone, 20 had spinal cord or nerve root injury and 12 had peripheral nerve injury. A simple fall on the hill was the commonest method of injury, followed in frequency by collision with a tree, which caused the most severe injuries. Reckless skiing, design of ski runs and man-made snow were contributing factors. The serious nature and number of these injuries must be recognized, and further study is needed on causal factors and preventive measures.
