Advantage In Health Research Articles

Do conservatives really have an advantage in mental health? Anexamination of measurement invariance.

Many studies have found that conservatives show an advantage in mental health and happiness and various causes of this have been debated (e.g., religiousness, ideology, or genetics). However, not much attention has been given to examining whether this advantage is psychometrically real, or whether it is due to test bias. We analyzed data from two large Finnish surveys of adults (Ns = 848 and 4,978) from Lahtinen (2024), that measured general anxiety and depression symptoms, as well as a new wokeness scale. Using differential item functioning tests, we found no evidence for measurement bias in these scales. The correlation between index scores of wokeness and mental health (internalizing) was -0.36, which increased to -0.41 when measurement error was removed. The association between wokeness and anxiety (r = -0.33, adjusted r = 0.37) was stronger than wokeness and depression (r = 0.20, adjusted r = 0.22).

The role of pharmaceutical side-effects in depression among immigrants

ABSTRACT 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.

A contextual exploration of healthcare service use in urban slums in Nigeria.

IntroductionMany urban residents in low- and middle-income countries live in unfavorable conditions with few healthcare facilities, calling to question the long-held view of urban advantage in health, healthcare access and utilization. We explore the patterns of healthcare utilization in these deprived neighborhoods by studying three such settlements in Nigeria.MethodsThe study was conducted in three slums in Southwestern Nigeria, categorized as migrant, indigenous or cosmopolitan, based on their characteristics. Using observational data of those who needed healthcare and used in-patient or out-patient services in the 12 months preceding the survey, frequencies, percentages and odds-ratios were used to show the study participants’ environmental and population characteristics, relative to their patterns of healthcare use.ResultsA total of 1,634 residents from the three slums participated, distributed as 763 (migrant), 459 (indigenous) and 412 (cosmopolitan). Residents from the migrant (OR = 0.70, 95%CI: 0.51 to 0.97) and indigenous (OR = 0.65, 95%CI: 0.45 to 0.93) slums were less likely to have used formal healthcare facilities than those from the cosmopolitan slum. Slum residents were more likely to use formal healthcare facilities for maternal and perinatal conditions, and generalized pains, than for communicable (OR = 0.50, 95%CI: 0.34 to 0.72) and non-communicable diseases (OR = 0.61, 95%CI: 0.41 to 0.91). The unemployed had higher odds (OR = 1.45, 95%CI: 1.08 to 1.93) of using formal healthcare facilities than those currently employed.ConclusionThe cosmopolitan slum, situated in a major financial center and national economic hub, had a higher proportion of formal healthcare facility usage than the migrant and indigenous slums where about half of families were classified as poor. The urban advantage premise and Anderson behavioral model remain a practical explanatory framework, although they may not explain healthcare use in all possible slum types in Africa. A context-within-context approach is important for addressing healthcare utilization challenges in slums in sub-Saharan Africa.

Differences in post-disaster mental health among Vietnamese and African Americans living in adjacent urban communities flooded by Katrina.

Some communities recover more quickly after a disaster than others. Some differentials in recovery are explained by variation in the level of disaster-related community damage and differences in pre-disaster community characteristics, e.g., the quality of housing stock. But distinct communities that are similar on the above characteristics may experience different recovery trajectories, and, if so, these different trajectories must be due to more subtle differences among them. Our principal objective is to assess short-term and long-term post-disaster mental health for Vietnamese and African Americans living in two adjacent communities in eastern New Orleans that were similarly flooded by Hurricane Katrina. We employ data from two population-based cohort studies that include a sample of African American adults (the Gulf Coast Child and Family Health [GCAFH study]) and a sample of Vietnamese American adults (Katrina Impacts on Vietnamese Americans [KATIVA NOLA study]) living in adjacent neighborhoods in eastern New Orleans who were assessed near the second and thirteenth anniversaries of the disaster. Using the 12-Item Short Form Survey (SF-12) as the basis of our outcome measure, we find in multivariate analysis a significant advantage in post-disaster mental health for Vietnamese Americans over their African American counterparts at the two-year mark, but that this advantage had disappeared by the thirteenth anniversary of the Katrina disaster.

The Citizenship Advantage in Psychological Well-being: An Examination of the Hukou System in China.

Given that Chinese migrants with rural hukou status are not considered full citizens in their urban destinations, rural-urban hukou conversion signifies full citizenship attainment in urban China. We assess causal effects of three major types of urban hukou attainment-merit-, policy-, and family-based hukou conversion-on migrants' psychological well-being in middle- and later-life. We further examine how hukou matters-how periods and hukou destinations alter the values of specific urban hukou and their psychological health implications for individuals. We use the China Health and Retirement Longitudinal Study (2015 data) and life history data (for 2014) for analysis. To assess the extent to which the salmon effect contributes to estimation bias for migrants, we compare results from a sample with current migrants and one with current and returned migrants. To address for selection into hukou conversion, we adopt inverse probability-weighted regression adjustment methods. We show that the salmon bias significantly dampened causal estimates. Merit- and policy-based hukou conversion has protective effects on psychological well-being. Policy-based converters have better psychological health than other types of converters. Hukou conversion in the pre-1978 period conveys greater psychological benefits than that in the post-1998 period, when economic and social values of urban hukou have decreased. Hukou converters in the cities with the most resources enjoy better psychological well-being than their counterparts in other cities. Our study joins the emerging literature in investigating how citizenship conveys advantage in health and well-being. We discuss these results in the global context as well as the context of China's decades of evolution of hukou policy and the urbanization process.

Life expectancy and mortality in 363 cities of Latin America

The concept of a so-called urban advantage in health ignores the possibility of heterogeneity in health outcomes across cities. Using a harmonized dataset from the SALURBAL project, we describe variability and predictors of life expectancy and proportionate mortality in 363 cities across nine Latin American countries. Life expectancy differed substantially across cities within the same country. Cause-specific mortality also varied across cities, with some causes of death (unintentional and violent injuries and deaths) showing large variation within countries, whereas other causes of death (communicable, maternal, neonatal and nutritional, cancer, cardiovascular disease and other noncommunicable diseases) varied substantially between countries. In multivariable mixed models, higher levels of education, water access and sanitation and less overcrowding were associated with longer life expectancy, a relatively lower proportion of communicable, maternal, neonatal and nutritional deaths and a higher proportion of deaths from cancer, cardiovascular disease and other noncommunicable diseases. These results highlight considerable heterogeneity in life expectancy and causes of death across cities of Latin America, revealing modifiable factors that could be amenable to urban policies aimed toward improving urban health in Latin America and more generally in other urban environments.

Effects of the brown algae Sargassum horneri and Saccharina japonica on survival, growth and resistance of small sea urchins Strongylocentrotus intermedius

Mass mortality of the long line culture of the sea urchin Strongylocentrotus intermedius in summer, which is greatly associated with their disease, energy storage and resistant abilities, is the most serious problem for the development of the aquaculture. Here, a feeding experiment was conducted for ~ 9 weeks to investigate the survival, growth and gonadal development of small S. intermedius (~ 3 cm) fed either brown algae Sargassum horneri or Saccharina japonica. Subsequently, we assessed their resistant abilities via observing the behaviors of righting, tube feet extension and Aristotle's lantern reflex at both moderately elevated and acutely changed water temperatures. Sea urchins fed S. horneri showed significantly fewer diseased individuals and slower gonadal development than those fed S. japonica. Consistently, significantly greater Aristotle's lantern reflex occurred in sea urchins fed S. horneri at moderately elevated temperatures. These findings suggest that S. horneri has direct application potential as food for the long line culture of S. intermedius in summer because of the advantage in health, energy storage (avoid the energy loss caused by gonadal development at small body sizes) and resistance abilities. In comparison, sea urchins fed S. japonica outperformed those fed S. horneri for all experimental behaviors under the acutely changed water temperatures. These findings clearly suggest that S. intermedius fed S. japonica is more suitable for the areas with cold water mass in summer, because it can effectively avoid or reduce the negative impacts of acute changes of water temperature on sea urchins. The present study provides valuable information into the management of the long line culture of S. intermedius in summer.

Racial stratification in self-rated health among Black Mexicans and White Mexicans.

How do Mexicans of distinct racial backgrounds fit into the recognized patterns of racial health disparities? We conduct regression analyses using data from the 2000-2017 National Health Interview Survey to determine if Mexicans who self-identify as White or Black have a relative advantage or disadvantage in self-rated health in relation to Non-Hispanic (NH) Whites and Blacks in the U.S. Our results indicate that both Black Mexicans and White Mexicans have a significant disadvantage in relation to NH-Whites while White Mexicans have a slight advantage in relation to both NH-Blacks and Black Mexicans. Overall, our results suggest that studying health outcomes among Hispanics without considering race may mask inequalities not observed in the aggregate.

Bisexuality, Union Status, and Gender Composition of the Couple: Reexamining Marital Advantage in Health.

It has long been documented that married individuals have better health outcomes than unmarried individuals. However, this marital advantage paradigm has been developed primarily based on heterosexual populations. No studies to date have examined the health effects of marriage among bisexuals, one of the most disadvantaged but understudied sexual minority groups, although a few have shown mixed results for gays and lesbians. Similarly, no research has examined how the gender composition of a couple may shape bisexuals' health outcomes above and beyond the effects of sexual orientation. We analyzed pooled data from the 2013-2017 National Health Interview Survey (n = 154,485) and found that the health advantage of marriage applied only to heterosexuals and, to a lesser extent, gays and lesbians. Married bisexuals, however, exhibited poorer health than unmarried bisexuals when socioeconomic status and health behaviors were adjusted for. Moreover, bisexuals in same-gender unions were healthier than bisexuals in different-gender unions primarily because of their socioeconomic advantages and healthier behaviors. Together, our findings suggest that bisexuals, particularly those in different-gender unions, face unique challenges in their relationships that may reduce the health advantage associated with marriage.

Is the story about sensitive women and stoical men true? Gender differences in health after adjustment for reporting behavior

Research indicates that women have higher levels of physical disability and depression and lower scores on physical performance tests compared to men, while the evidence for gender differences in self-rated health is equivocal. Scholars note that these patterns may be related to women over-reporting and men under-reporting health problems, but gender differences in reporting behaviors have not been rigorously tested. Using Wave 1 of the Survey of Health, Ageing and Retirement in Europe (SHARE), the present study investigates the extent to which adjusting for differences in reporting behavior modifies gender differences in general health. We also examine whether men and women's reporting behaviors are consistent across different levels of education. After adjusting for reporting heterogeneity, gender differences in both poor and good health widened. However, we found no clear gender-specific patterns in reporting either poor or good health. Our findings also do not provide convincing evidence that education is an important determinant of general health reporting, although the female disadvantage in poor health and the male advantage in good health were more apparent in lower than higher education groups at all ages. The results challenge prevailing stereotypes that women over-report and men under-report health problems and highlight the importance of attending to health problems reported by women and men with equal care.

Trends in gender differences in health at working ages among West and East Germans

Before 1990, Germany was divided for more than 40 years. While divided, significant mortality disparities between the populations of East and West Germany emerged. In the years following reunification, East German mortality improved considerably, eventually converging with West German levels. In this study, we explore changes in the gender differences in health at ages 20–59 across the eastern and western regions of Germany using data from the German Socio-Economic Panel (SOEP) for the 1990–2013 period. We apply random-effects linear regressions to the SOEP data to identify trends in health, measured as self-assessed health satisfaction, after German reunification.The findings indicate that women were substantially less satisfied with their health than men in both West and East Germany, but that the gender gap was larger in East Germany than in West Germany. Furthermore, the results show that respondents’ satisfaction with their health decreased over time, and that the decline was steeper among men – and particularly among East German men – than among women. Thus, the initial male advantage in health in East and West Germany in the years immediately after reunification diminished over time, and even reversed to become a female advantage in East Germany. One interpretation of this finding is that stress-inducing post-reunification changes in the political and social landscape of East Germany had lasting damaging consequences for men’s health.Ongoing risky health behaviors and high levels of economic insecurity due to unemployment could have had long-lasting effects on the health of the working-aged population. A partial explanation for our finding that health declined more sharply among East German men than among their female counterparts could be that women have better compensatory mechanisms than men for dealing with psychosocial stress.

Not all built the same? A comparative study of electoral systems and population health

Much literature depicts a worldwide democratic advantage in population health. However, less research compares health outcomes in the different kinds of democracy or autocracy. In an examination of 179 countries as they existed between 1975 and 2012, advantages in life expectancy and infant health appear most reliably for democracies that include the principle of proportional representation in their electoral rules. Compared to closed autocracies, they had up to 12 or more years of life expectancy on average, 75% less infant mortality, and double the savings in overall mortality for most other age groups. Majoritarian democracies, in contrast, did not experience longitudinal improvements in health relative to closed autocracies. Instead their population health appeared to be on par with or even superseded by competitive autocracies in most models. Findings suggest that the principle of proportional representation may be good for health at the national level. Implications and limitations are discussed.

Urban Health in Tanzania: Questioning the Urban Advantage

How are health inequalities articulated across urban and rural spaces in Tanzania? This research paper explores the variations, differences, and inequalities, in Tanzania's health outcomes-to question both the idea of an urban advantage in health and the extent of urban-rural inequalities in health. The three research objectives aim to understand: what are the health differences (morbidity and mortality) between Tanzania's urban and rural areas; how are health inequalities articulated within Tanzania's urban and rural areas; and how are health inequalities articulated across age groups for rural-urban Tanzania? By analyzing four national datasets of Tanzania (National Census, Household Budget Survey, Demographic Health Survey, and Health Demographic Surveillance System), this paper reflects on the outcomes of key health indicators across these spaces. The datasets include national surveys conducted from 2009 to 2012. The results presented showcase health outcomes in rural and urban areas vary, and are unequal. The risk of disease, life expectancy, and unhealthy behaviors are not the same for urban and rural areas, and across income groups. Urban areas show a disadvantage in life expectancy, HIV prevalence, maternal mortality, children's morbidity, and women's BMI. Although a greater level of access to health facilities and medicine is reported, we raise a general concern of quality and availability in health services; what data sources are being used to make decisions on urban-rural services, and the wider determinants of urban health outcomes. The results call for a better understanding of the sociopolitical and economic factors contributing to these inequalities. The urban, and rural, populations are diverse; therefore, we need to look at service quality, and use, in light of inequality: what services are being accessed; by whom; for what reasons?

Health returns to education by family socioeconomic origins, 1980–2008: Testing the importance of gender, cohort, and age

Recent studies find that health returns to education are elevated among those who come from disadvantaged families. These findings suggest that education may be a health resource that compensates or “substitutes” for lower parental socioeconomic status. Alternatively, some studies find support for a cumulative (dis)advantage perspective, such that educational health returns are higher among those who already were advantaged, widening initial health (dis)advantages across the life course. However, it remains unclear whether these findings are dependent on gender or cohort, and this is a fundamental oversight given marked differences between men and women in educational and health inequalities across the twentieth century. Drawing on national US data (1980–2002 General Social Survey with 2008 National Death Index Link), I indeed find that the presence or strength of resource substitution or cumulative (dis)advantage depends upon health measure as well as gender and cohort. For self-rated health, cumulative (dis)advantage explains educational health disparities, but among men only. Cumulative (dis)advantage in avoiding fair or poor health is partly explained by cohort and age variation in health returns to education, and cumulative (dis)advantage in excellent health is more robust in earlier cohorts and at older ages. For mortality, resource substitution is instead supported, but for women only. Among those from disadvantaged families, educational mortality buffering increases with cohort but diminishes with age. Taken together, these findings confirm prior research showing that adult health inequalities linked to education depend on family background, and extend this work by demonstrating that the nature and extent of these dynamics differ considerably depending on the health outcome being assessed and on an individual's historical context, life course stage, and gender.

An Age-Period-Cohort Analysis of Religious Involvement and Adult Self-Rated Health: Results from the USA, 1972-2008.

This study conducts an age, period, cohort analysis of how religious involvement affects adult health across the life course and over time in the USA. Cross-classified random-effect models are used to examine data drawn from the General Social Survey, 1972-2008. The research shows clear life course patterns, time trends and birth cohort changes in the religious involvement and health relationship with period effects surpassing cohort effects. For the most part, the results show a loss of advantage in health with age for those who are more involved in religion. Period effects are mainly demonstrated by an overall downward trend of self-rated health (SRH) attributable to religious denominational differences and various levels of social integration. Unlike the period effects, the health disparities associated with religious denominational differences fluctuated when cohort progressed. These findings suggest that in general, the positive effect of religious involvement on SRH decreases with age and periods, but its influence on individual SRH fluctuates by cohort. It is expected that a downward trend in SRH attributable to religious involvement will carry on in future.

Healthy(?), wealthy, and wise: Birth order and adult health

While recent research has found that birth order affects outcomes such as education and earnings, the evidence for effects on health is more limited. This paper uses a large Norwegian dataset to focus on the relationship between birth order and a range of health and health-related behaviors, outcomes not previously available in datasets of this magnitude. Interestingly, we find complicated effects of birth order. First-borns are more likely to be overweight, to be obese, and to have high blood pressure and high triglycerides. For example, compared to fifth-borns, first-borns are about 5% points more likely to be obese and 7% points more likely to have high blood pressure. So, unlike education or earnings, there is no clear first-born advantage in health. However, first-borns are about 13% points less likely to smoke daily than fifth-borns and are more likely to report good physical and mental health. Later-borns also score lower on well-being with fifth-borns being about 9% points less likely than first-borns to report that they are happy. Our findings are generally monotonic with middle-borns having outcomes that are intermediate between first- and fifth-borns. We find that these effects are largely unaffected by conditioning on education and earnings, suggesting that these are not the only important pathways to health differentials by birth order. When we explore possible mechanisms, we find that early maternal investment may play a role in birth order effects on health.

Politics and population health: Testing the impact of electoral democracy

This study addresses questions of whether and why electoral democracies have better health than other nations. After devising a replicable approach to missing data, we compare political, economic, and health-related data for 168 nations collected annually from 1960 through 2010. Regression models estimate that electoral democracies have 11 years of longer life expectancy on average and 62.5% lower rates of infant mortality. The association with life expectancy reduces markedly after controlling for GDP, while a combination of factors may explain the democratic advantage in infant health. Results suggest that income inequality associates independently with both health outcomes but does not mediate their associations with democracy.

Sex differences in health and mortality in Moscow and Denmark

In high income countries females outlive men, although they generally report worse health, the so-called male-female health-survival paradox. Russia has one of the world's largest sex difference in life expectancy with a male disadvantage of more than 10 years. We compare components of the paradox between Denmark and Moscow by examining sex differences in mortality and several health measures. The Human Mortality Database and the Russian Fertility and Mortality Database were used to examine sex differences in all-cause death rates in Denmark, Russia, and Moscow in 2007-2008. Self-reported health data were obtained from the Study of Middle-Aged Danish Twins (n = 4,314), the Longitudinal Study of Aging Danish Twins (n = 4,731), and the study of Stress, Aging, and Health in Russia (n = 1,800). In both Moscow and Denmark there was a consistent female advantage at ages 55-89 years in survival and a male advantage in self-rated health, physical functioning, and depression symptomatology. Only on cognitive tests males performed similarly to or worse than women. Nevertheless, Muscovite males had more than twice higher mortality at ages 55-69 years compared to Muscovite women, almost double the ratio in Denmark. The present study showed that despite similar directions of sex differences in health and mortality in Moscow and Denmark, the male-female health-survival paradox is very pronounced in Moscow suggesting a stronger sex-specific disconnect between health indicators and mortality among middle-aged and young-old Muscovites.

Offline: The state of public health (research) in the UK

At a recent meeting in a leading London research-intensive university, a respected professor of public health reported to colleagues from overseas that the UK was “in danger of losing our comparative advantage in academic public health”. She was ringing an alarm bell about the effects of the Coalition Government's NHS reforms, which she described as “chaotic”. But she was also signalling her concerns about the future of public health research. Her warning was not made lightly. Given the current direction and pace of NHS reforms, public health research could be irreversibly harmed. A year ago, recognising that these threats were real, a small group of concerned individuals came together to plan Public Health Science: a National Conference Dedicated to New Research in Public Health. This 1-day meeting, being held on Nov 23 at the Royal Society of Medicine, is jointly organised by the London School of Hygiene and Tropical Medicine, the National Heart Forum, and The Lancet. The meeting will “showcase the exceptional talent and creativity in the UK public health research community”. Great thanks are due to Rob Aldridge, Katie Cole, Louise Hurst, Neeraj Bhala, Rachel Catley, Simon Capewell, Klim McPherson, and Martin McKee for a tremendous amount of work to make this unusual event possible. The purpose of the meeting is two-fold. First, to provide a forum to present and debate the very best public health science in the UK. And second, to show how vibrant and successful public health research in Britain is today, and why it should be cherished, protected, and strengthened as a vital national asset. The research reported at this meeting amply fulfils both these ambitions.
