Does the predictive power of self-rated health for subsequent mortality risk vary by socioeconomic status in the US?

Building Financial Capability and Assets to Reduce Poverty and Health Disparities: Race/Ethnicity Matters

BACKGROUND

Evidence has documented racial wealth inequity as one of the key pathways linking structural racism and racial health inequity. Most prior studies on the wealth-health relationship use net worth as the measure of wealth. This approach provides little evidence on the most effective interventions as various types of assets and debt affect health differently. This paper examines how U.S. young adults' wealth components (e.g., financial assets, nonfinancial assets, secured debt, and unsecured debt) are associated with physical and mental health, and if the associations differ by race/ethnicity.

METHODS

Data were drawn from the National Longitudinal Survey of Youth 1997. Health outcomes were measured by mental health inventory and self-rated health. Logistic regressions and ordinary least square regressions were used to assess the association between wealth components and physical and mental health.

RESULTS

I found that financial assets and secured debt were positively associated with self-rated health and mental health. Unsecured debt was negatively associated with mental health only. The positive associations between financial assets and health outcomes were significantly weaker for non-Hispanic Black respondents. Unsecured debt was protective of self-rated health for non-Hispanic Whites only. For Black young adults, unsecured debt had more severe negative health consequences compared to other racial/ethnic groups.

CONCLUSION

This study provides a nuanced understanding of the complex relationship among race/ethnicity, wealth components, and health. Findings could inform asset building and financial capability policies and programs to effectively reduce racialized poverty and health disparities.

Disparities in prevalence and treatment of diabetes, cardiovascular and chronic kidney diseases - Recommendations from the taskforce of the guideline workshop

There is a mounting clinical, psychosocial, and socioeconomic burden worldwide as the prevalence of diabetes, cardiovascular disease (CVD), and chronic kidney disease (CKD) continues to rise. Despite the introduction of therapeutic interventions with demonstrated efficacy to prevent the development or progression of these common chronic diseases, many individuals have limited access to these innovations due to their race/ethnicity, and/or socioeconomic status (SES). However, practical guidance to providers and healthcare systems for addressing these disparities is often lacking. In this article, we review the prevalence and impact of healthcare disparities derived from the above-mentioned chronic conditions and present broad-based recommendations for improving access to quality care and health outcomes within the most vulnerable populations.

Disparities in Olfactory Dysfunction in African Americans

OBJECTIVES

To examine olfactory performance in African Americans (AA) and Whites by comparing individual scent scores on objective olfactory tests to assess potential racial-ethnic differences of scent detection.

METHODS

Cross-sectional study of healthy participants, age 18+ years, and without sinonasal inflammatory disease from June 2021 to April 2022. Included participants self-identified as AA or White. Patients were recruited from outpatient clinics at University of Kansas Medical Center, and the local community. Two smelling tests were employed: Affordable Rapid Olfactory Measurement Array (AROMA) and Sniffin' Sticks (SST-12). Sino-Nasal Outcome Test (SNOT-22) was used for self-reported olfactory function . Pearson correlation and chi-square tests were used to detect statistical significance.

RESULTS

Our sample included 102 (46 AA and 56 Whites) participants. AROMA and SST-12 scores were significantly correlated in AA (P < .01, Pearson's Rho = .642) and Whites (P < .05, Pearson's Rho = .297). Mean scores on AROMA were significantly lower for AAs: 64.2 and Whites: 75.5 (P < .01). On AROMA, AA less accurately identified the scents of Licorice, Orange, Lavender, Cinnamon, Clove, and Rosemary (P < .05). Similarly, SST-12 mean scores for AAs: 84.2 were also lower than Whites: 89.9 (P < .01). On SST-12, AA less accurately identified the scent of pineapple Based on SST-12 scoring criteria, 60.9% of AA and 30.4% of Whites were classified as hyposmic (P < .05). SNOT-22 Smell scores were equivalent for both groups.

CONCLUSION

On both tests of olfaction, AA performed worse than Whites and a greater proportion of AA were considered hyposmic compared to Whites. This is a discrepancy with self-reported olfaction, which showed no difference between Whites and AA. AA performed significantly worse than their White counterparts on several scents, with possible implications regarding cultural appropriateness of scents used in olfactory testing.

Assessing the impact of caregiving for older parents on caregivers' health: Initial health status and trajectories of physical and mental health among midlife caregivers for parents and parents-in-law in Britain

Assessing the impact of caregiving for older parents on caregivers' health is increasingly important in the context of population changes and curtailment of state provided services. This has been extensively studied but results are inconsistent, possibly reflecting a lack of attention to health-related selection into the caregiver role. We use data from a nationally representative UK longitudinal study to analyse differences in the health of people aged 40-69 at baseline by whether they were 'eligible' to provide parent care (with a living parent/parent-in-law) and by whether they subsequently assumed a caregiver role. We measured initial health status using a latent variable derived from three observer-recorded indicators as well as self-reported health. We analysed trajectories of physical and mental health over a seven-year follow-up for those providing intensive care (20+ hours per week) to a parent or parent-in-law, providers of lesser amounts of care, and non-caregivers. Outcomes were measured using the SF-12 indicators of mental and physical health. RESULTS: showed that those with a living parent or parent-in-law had better health than those lacking these relatives. However, among potential caregivers for a parent or parent-in-law, those assuming intensive caregiving had poorer initial health than non-caregivers or those who became providers of less intensive care. Fixed effects analyses of follow-up data showed that the mental health of intensive caregivers deteriorated. However, the physical health of intensive caregivers with low levels of education improved. RESULTS: show the importance of taking account of whether people are at risk of providing parental care and initial health status when assessing impacts of caregiving on health. They also indicate differential effects of caregiving on health depending on socio-demographic characteristics and reaffirm the need for greater supports for those providing substantial amounts of care to older parents.

Specific domains of positive childhood experiences (PCEs) associated with improved adult health: A nationally representative study

Background

Positive childhood experiences (PCEs) are supportive relationships and environments associated with improved health when aggregated into composite scores. Adverse childhood experiences (ACEs), a reciprocal measure to PCEs, are associated with worse health in aggregate scores and when disaggregated into measures of specific ACE types (hereafter domains). Understanding the associations between specific PCE domains and health, while accounting for ACEs, may direct investigations and intervention planning to foster PCE exposure.

Methods

We analyzed data from the nationally representative United States longitudinal Panel Study of Income Dynamics. Five PCE domains were examined: (i) peer support and healthy school climate, (ii) neighborhood safety, (iii) neighborhood support, and nurturing relationships with (iv) maternal and (v) paternal figures. Survey weighted logistic regression models tested associations between each PCE domain measure and adult general health rating, controlling for demographic covariates and nine ACE exposures: physical, emotional, or sexual abuse/assault; emotional neglect; witnessing intimate partner violence or household substance use; having a parent with mental illness; any parental separation or divorce; and/or having a deceased or estranged parent. Secondary outcomes included adult functional status and mental and physical health diagnoses. We also tested for statistical interactions between PCE domain and ACE score measures.

Results

The sample included 7105 adults. Higher scores for the "peer support and healthy school climate" and "neighborhood safety" domain measures showed the most protective relationships with the adverse health conditions tested, most notably for mental illness. The relationship between PCE domain measures and health outcomes was attenuated, but not statistically moderated by ACE exposure.

Conclusion

Experiencing childhood peer support, a healthy school climate, and neighborhood safety were especially protective against multiple adult health conditions, including for ACE exposed individuals. Interventions that promote PCEs may yield population health gains.

Advancing Universal Oral Health Coverage via Person-Centred Outcomes

The World Health Organization member states proposed a comprehensive "Global Strategy on Oral Health," which includes achieving universal oral health coverage by 2030. Challenges and barriers, including persistent inequalities, will hamper the achievement of universal oral health coverage. In low- and middle-income countries, the oral health of a large proportion of the population has been neglected, increasing oral health inequalities. In high-income countries, some receive excessive dental treatment, whilst particularly those with higher needs receive too little dental care. Therefore, an analysis of individual countries' needs, encompassing the training of oral health professionals in a new philosophy of care and attention and the optimisation of the existing resources, is necessary. Distancing from a person-centred focus has prompted individual and societal issues, including under-/overdiagnosis and under-/overtreatment. The person-centred approach considers the perceptions, needs, preferences, and circumstances of individuals and populations. Patient-reported outcome measures, such as self-rated and -reported health, reflect an individual's overall perception of health and are designed to mediate human biology (ie, the disease) and psychology. The usage of patient-reported outcome measures in dentistry to place the individual at the centre of treatment is delayed compared to other areas. This paper discusses some challenges and potential solutions of patient-reported outcome measures in dentistry for achieving universal oral health coverage.

Education and age trajectories of chronic conditions: Are tests of the cumulative advantage and disadvantage hypothesis biased by underreporting?

OBJECTIVE

This study examined the impact of underreporting on tests of the cumulative advantage and disadvantage hypothesis (CAD), which predicts age-related increases in health disparities between individuals with higher and lower education.

METHODS

Using the English Longitudinal Study of Ageing (ELSA), we identified underreporting by comparing self-reported hypertension and diabetes with biomedically measured hypertension (systolic blood pressure≥140 mm Hg and/or diastolic blood pressure≥90 mm Hg) and diabetes (fasting glucose level≥7 mmol/l and/or HbA1c≥6.5%). In a sample of 11,859 respondents aged 50 to 85 (54% women, 97% White), we assessed the associations between underreporting and the main analytic constructs in tests of the CAD (education, age, sex, and cohort).

RESULTS

The results showed that self-reported measures underestimated the prevalence of hypertension and diabetes. Underreporting showed weak to moderate associations with the main constructs in tests of the CAD, being more pronounced in individuals with lower education, in older age, in more recent cohorts, and among men. When correcting for underreporting using biomedical measures, the overall prevalence of hypertension and diabetes increased substantially, but education differences in age trajectories of both conditions remained similar.

CONCLUSIONS

Underreporting affected conclusions about the prevalence of hypertension and diabetes, but it did not affect conclusions about the CAD hypothesis for either condition.

The relationship between neighborhood typologies and self-rated health in Maryland: A latent class analysis

Despite widespread evidence that neighborhood conditions impact health, few studies apply theory to clarify the physical and social factors in communities that drive health outcomes. Latent class analysis (LCA) addresses such gaps by identifying distinct neighborhood typologies and the joint influence that neighborhood-level factors play in health promotion. In the current study, we conducted a theory-driven investigation to describe Maryland neighborhood typologies and examined differences in area-level self-rated poor mental and physical health across typologies. We conducted an LCA of Maryland census tracts (n = 1384) using 21 indicators of physical and social characteristics. We estimated differences in tract-level self-rated physical and mental health across neighborhood typologies using global Wald tests and pairwise comparisons. Five neighborhood classes emerged: Suburban Resourced (n = 410, 29.6%), Rural Resourced (n = 313, 22.6%), Urban Underserved (n = 283, 20.4%), Urban Transient (n = 226, 16.3%), Rural Health Shortage (n = 152, 11.0%). Prevalence of self-rated poor physical and mental health varied significantly (p < 0.0001) by neighborhood typology, with the Suburban Resourced neighborhood class demonstrating the lowest prevalence of poor health and the Urban Underserved neighborhoods demonstrating the poorest health. Our results highlight the complexity of defining "healthy" neighborhoods and areas of focus to mitigate community-level health disparities to achieve health equity.

Health-Related Quality of Life after Cataract Surgery in Armenia: A Cross-Sectional Survey

Cataract surgery helps to enhance visual function and improve the quality of life of cataract patients. The present study assessed visual outcomes and explored health-related quality of life (HRQoL) and factors associated with it following cataract surgery in Armenia. An interviewer-administered survey along with the ophthalmologic examination was conducted among 248 patients. It explored socio-demographic characteristics, use of eye care services, smoking status, comorbidities, and receiving and giving social support. A Short Form Health Survey (SF-36) was used to measure HRQoL. Simple and multivariable linear regression was used for the analysis. About 72.8% of examined eyes had good visual outcomes, while 17.7% had borderline outcomes. Poor visual outcomes were detected in 9.5% of the eyes. The mean composite SF-36 score for physical health was 50.8, while the mean composite score for mental health was 49.9. Gender, socioeconomic status, having a non-communicable disease, and receiving and giving tangible social support were significantly associated with SF-36 physical component in the adjusted analysis, while the variables which demonstrated significant association with the mental component included socioeconomic status, having a non-communicable disease, and giving tangible support. The visual outcome after cataract surgery in Armenian patients is below WHO-recommended standards. The quality of ophthalmological surgical care should be monitored to maximize the visual outcome in Armenian patients, with a focus on women, patients with poor socioeconomic status, and those with non-communicable diseases.

Diabetes Moderates the Link between Personality Traits and Self-Rated Health (SRH)

OBJECTIVES

The primary objective of this study is to explore the relationship between personality traits and self-rated health (SRH) in individuals with diabetes, while also comparing these associations with a group of healthy controls.

METHODS

The data for this study were obtained from the UK Household Longitudinal Study (UKHLS), comprising a sample of 1860 diabetes patients and 12,915 healthy controls who were matched in terms of age and sex. Hierarchical linear regression was utilized to analyze the data. The analysis included demographic variables such as age, sex, monthly income, highest educational qualification, marital status, and psychological distress assessed through the GHQ-12, personality traits, including Neuroticism, Agreeableness, Openness, Conscientiousness, and Extraversion, and diabetes status (0 for diabetes patients, 1 for healthy controls) as predictors. Interactions between personality traits and diabetes status were also included as predictors, with SRH serving as the dependent variable. Additionally, separate multiple regression analyses were conducted for diabetes patients and healthy controls, incorporating demographic variables, psychological distress, and personality traits as predictors, while SRH remained the dependent variable.

RESULTS

The findings of this study indicate that diabetes significantly moderates the association between Neuroticism and SRH. Specifically, both Neuroticism and Extraversion were negatively associated with SRH, whereas Openness and Conscientiousness exhibited a positive association with SRH in healthy controls. However, among diabetes patients, only Conscientiousness showed a positive association with SRH.

CONCLUSION

Personality traits predict SRH in people with and without diabetes differently. Healthcare professionals and clinicians should try to come up with ways that improve SRH and thus better outcomes in diabetes patients based on the findings from the current study.

Self-Rated Health and Mortality: Moderation by Purpose in Life

Poor self-rated health consistently predicts reduced longevity, even when objective disease conditions and risk factors are considered. Purpose in life is also a reliable predictor of diverse health outcomes, including greater longevity. Given prior work in which we showed that purpose in life moderated the association between chronic conditions and health-related biological factors, the aim of the current study was to examine the role of purpose in life in moderating the relationship between subjective health and mortality. We also examined potential differences in these associations by race/ethnicity. Data were from two large national longitudinal studies-the Health and Retirement Study (HRS) and the Midlife in the United States (MIDUS) study-with a 12- to 14-year follow-up period for mortality estimates. Results of logistic regression analyses showed that purpose in life and self-rated health were both significantly positively associated with longevity, and that purpose in life significantly moderated the relationship between self-rated health and mortality. Stratified analyses showed similar results across all racial/ethnic groups, with the exception of Black MIDUS participants. These results suggest that greater purpose in life may provide a buffer against the greater probability of mortality associated with poor subjective health.

Self-assessed health status and obesity vulnerability in rural Louisiana: A cross-sectional analysis

Rural communities are resource-constrained and at higher risk of obesity and obesity-related conditions. Thus, studying self-assessed health status and underlying vulnerabilities is critical to provide insights to the program planners for effective and efficient planning of obesity prevention programs. This study aims to investigate the correlates of self-assessed health status and subsequently determine the obesity vulnerability level of residents in rural communities. Randomly sampled data were obtained from in-person community surveys in three rural Louisiana counties-East Carroll, Saint Helena, and Tensas-in June 2021. The association of social-demographic factors, grocery store choice, and exercise frequency with self-assessed health was investigated using the ordered logit model. An obesity vulnerability index was constructed using the weights obtained from the principal component analysis. The results show that gender, race, education, possession of children, exercise frequency, and grocery store choice significantly influence self-assessed health status. Around 20% of respondents fall into the most-vulnerable segment and 65% of respondents are vulnerable to obesity. The obesity vulnerability index ranged from -4.036 to 4.565, indicating a wide heterogeneity in the vulnerability level of rural residents. The findings show that the self-assessed health status of rural residents is not promising along with a high level of vulnerability to obesity. The findings from this study could serve as a reference in the policy discussion regarding an effective and efficient suite of interventions in rural communities to address obesity and promote well-being.

Relationships between Health Education, Health Behaviors, and Health Status among Migrants in China: A Cross-Sectional Study Based on the China Migrant Dynamic Survey

Managing the health of migrants has become a crucial aspect of promoting social harmony and cohesion in China. This study investigates the impact of public health education on the health status of migrants in China using cross-sectional data from the China Migrants Dynamic Survey 2017. A total of 169,989 migrants in China were selected as samples for empirical test. Data were analyzed using descriptive statistics, logistic regression, and the structural equation model. The findings show that health education significantly influences the health status of migrants in China. Specifically, health education related to occupational diseases, venereal diseases/AIDS, and self-rescue in public emergencies had a significant positive impact on migrants' health, while health education regarding chronic diseases had a significant negative impact. Health education delivered through lectures and bulletin boards had a significant positive impact on migrants' health, but online education had a significant negative effect on the health status of migrants. The effects of health education differ by gender and age, with a stronger positive impact on female migrants and elderly migrants aged 60 and above. The mediating effect of health behaviors was significant only in the total effect. In conclusion, health education can effectively enhance the health status of migrants in China by modifying their health behaviors.

People with Diabetes Have Poorer Self-Rated Health (SRH) and Diabetes Moderates the Association between Age and SRH

Diabetes is a severe chronic condition that is related to decreased physical functioning. Recently, there has been growing interest in understanding how a brief report on health such as self-rated health (SRH) could be used to track changes in health status and service needs in people with diabetes. The current research aims to investigate how SRH is affected by diabetes and how diabetes could moderate the association between age and SRH. By analyzing data from 47,507 participants, with 2869 of them clinically diagnosed with diabetes, the current study found that people with diabetes had significantly poorer SRH than people without diabetes after controlling for demographic covariates (t(2868) = -45.73, p < 0.001, 95% C.I. (-0.92, -0.85), Cohen's d = -0.85). In addition, diabetes was a significant moderator of the relationship between age and SRH (b = 0.01, p < 0.001, 95% C.I. (0.01, 0.01)). Specifically, age was more strongly related to SRH in people without diabetes (b = -0.015, p < 0.001, 95% C.I. (-0.016, -0.015)) than in people with diabetes (b = -0.007, p < 0.001, 95% C.I. (-0.010, -0.004)). Health professionals should aim to improve SRH in people with diabetes given that SRH is related to various outcomes.

Demandas e utilização de serviços de saúde entre imigrantes de uma região metropolitana do nordeste do Brasil

Resumo Objetivo analisar as demandas e a utilização dos serviços de saúde por imigrantes na Região Metropolitana de Aracaju, Sergipe. Método recrutaram-se, pelo método bola de neve, 186 imigrantes, alocados em clusters relacionados à renda per capita do país de origem e países da América Latina ou não. Utilizou-se questionário auto aplicado sobre as condições e práticas de saúde. Resultados imigrantes de países com renda baixa e média baixa (IMB) são mais jovens, com menor tempo de permanência no Brasil, possuem ensino fundamental/médio, exercem atividade laboral sem carteira de trabalho assinada e renda de até um salário mínimo (p<0,05). Imigrantes da América Latina (IAL) possuem aproximadamente duas vezes mais chances de ter alguma doença crônica não transmissível (DCNT), comparados aos imigrantes de outros países (IOP). A idade e o tempo de permanência no Brasil influenciam na autoavaliação da saúde, na busca por serviços de saúde e ter alguma DCNT (p<0,05). O Sistema Único de Saúde foi o mais buscado tanto na chegada ao Brasil quanto nos últimos 12 meses, principalmente pelos IMB e IAL (p<0,05). Conclusão e implicações para a prática observaram-se diferenças dentro dos subgrupos de imigrantes, principalmente em termos de padrões de utilização, ressaltando a importância da competência transcultural na assistência.

Demands and use of health services among immigrants from a metropolitan region in northeastern Brazil

Abstract Objective This study aimed to analyze the demands and use of health services by international migratory clusters in the metropolitan region of Aracaju, Sergipe. Method A total of 186 immigrants were recruited, and divided into clusters according to the country of origin and continent. An epidemiological questionnaire on health conditions and care-related. Results Low and low middle income country immigrants (LMI) are younger, with lower length of stay in Brazil, elementary education, working without a formal contract, with an income of up to 1 minimum wage (p<0.05). Latin America immigrants (LAI) are approximately twice as likely to have some Chronic noncommunicable disease (NCDs), compared to other country immigrants (OCI). Age and length of stay in Brazil influence self-rated health, search for health services and having some NCDs (p<0.05). The Unified Health System (Sistema Único de Saúde) was the most sought after both on arrival in Brazil and in the last 12 months, mainly by LMI and LAI (p<0.05). Conclusion and implications for practice Differences were observed within immigrant subgroups, mainly in terms of their use patterns and the importance for cross-cultural competence in health care.

Rural-Urban disparities in self-reported physical/mental multimorbidity: A cross-sectional study of self-reported mental health and physical health among working age adults in the U.S

Purpose

Self-rated physical health (SRPH) and self-rated mental health (SRMH) are both linked to excess morbidity and premature mortality and can vary across rural and urban contexts. This can be particularly problematic for rural residents who have less access to important health care infrastructure. In this paper, we assess the prevalence of and rural-urban disparities at the intersection of SRPH and SRMH, specifically self-rated physical/mental multimorbidity (SRPMM) overall and across rural-urban contexts.

Methods

Using a cross-sectional demographically representative national dataset of over 4000 working age adults in the U.S., we expose rural-urban differences in the prevalence of SRPMM and explore individual-level factors that may explain this disparity.

Results

Approximately 15 percent of working age adults reported SRPMM, but rural adults were at higher risk than their urban counterparts. However, this disadvantage disappeared for remote rural working-age adults and was attenuated for metro-adjacent rural working-age adults when we controlled for the fact that rural adults had lower household incomes.

Conclusion

Findings reveal a higher risk of SRPMM among rural adults, in part because of lower incomes among this group. This work acts as the foundation for facilitating research on and addressing rural-urban disparities in SRPMM.

Age Moderates the Link between Epilepsy and Self-Rated Health (SRH)

Epilepsy is one of the most severe neurological diseases that affect people around the globe. Self-rated health (SRH) refers to one’s subjective evaluation of their own health and is associated with various outcomes such as morbidity and mortality. Thus, understanding the association between epilepsy and SRH is of great importance. Moreover, SRH generally decreases with age. The aim of the current study is to test whether age moderates the link between epilepsy and SRH. The current study used a hierarchical regression and three multiple regressions to analyze the associations between epilepsy and SRH in 529 epilepsy patients and 46,978 healthy controls from the United Kingdom. The current study found that age significantly moderates the association between epilepsy and SRH. Specifically, epilepsy status was negatively related to SRH in young people (b = −0.69, p < 0.001, 95% C.I. [−0.84, −0.54]), more strongly in middle-aged adults (b = −0.81, p < 0.001, 95% C.I. [−0.95, −0.66]), and most strongly in older adults (b = −0.89, p < 0.001, 95% C.I. [−1.09, −0.69]). The current study may imply that older adults need more attention in terms of their SRH, which is closely associated with outcomes. Clinicians and health professionals should come up with ways that improve SRH in people with epilepsy, especially for older adults with epilepsy.

Reliability and predictive validity of two scales of self-rated health in China: results from China Health and Retirement Longitudinal Study (CHARLS)

Background

Despite the widespread use of the single item self-rated health (SRH) question, its reliability has never been evaluated in Chinese population.

Methods

We used data from the China Health and Retirement Longitudinal Study, waves 1–4 (2011–2019). In wave 1, the same SRH question was asked twice, separated by other questions, on a subset of 4533 subjects, allowing us to examine the test–retest reliability of SRH. In addition, two versions of SRH questions (the WHO and US versions) were asked (n = 11,429). Kappa (κ), weighted kappa (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\kappa}_{w}$$\end{document}κw), and polychoric correlation coefficient (ρ) were used for reliability assessment. Cox proportional-hazards models were estimated to assess the predictive validity of SRH measurement for mortality over 7 years of follow up. To do so, relative index of inequality (RII) and slope index of inequality (SII) were estimated for each SRH scale.

Results

There was moderate to substantial test–retest reliability (κ = 0.54, \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\kappa}_{w}$$\end{document}κw=0.63) of SRH; 31% of respondents who used the same scale twice changed their ratings after answering other questions. There was strong positive association between the two SRH measured by the two scales (ρ > 0.8). Compared with excellent/very good SRH, adjusted hazard ratios (HR) of death are 2.30 (95% CI, 1.70–3.13) for the US version and 1.86 (95% CI, 1.33–2.60) for the WHO version. Using slope indices of inequality, the WHO version estimated slightly larger mortality differences (RII = 3.50, SII = 15.53) than the US version (RII = 3.25, SII = 14.80).

Conclusions

In Chinese middle-aged and older population, the reliability of SRH is generally good, although the two commonly used versions of SRH scales could not be compared directly. Both indices predict mortality, with similar predictive validity.

Association between poor self-reported health and unmarried status among adults: examining the hypothesis of marriage protection and marriage selection in the Indian context

Background

The link between marital status and health differences has long been a topic of debate. The substantial research on marriage and health has been conducted under two important hypotheses: marital protection and marriage selection. While the majority of evidence on the marriage-health relationship using these hypotheses comes from developed countries, there is a lack of evidence from Asia, particularly from India.

Objectives

The current study examines theoretical frameworks of marriage i.e., marital protection and marriage selection in the Indian setting concurrently, bringing substantial empirical evidence to explore the link between marriage and health, considering this subject in the context of self-reported health (SRH). Secondly, this study will aid in investigating age and gender differences in marriage and health.

Methods

Using the Study on Global AGEing and Adult Health (SAGE), a cohort study of individuals aged 50 years and older with a small section of individuals aged 18 to 49 for comparative reasons, the present study population was 25 years and above individuals with complete marital information. Logistic regressions were employed to explore the connection between marital status and self-reported health. In the marriage protection hypothesis, the follow-up poor SRH was the dependent variable, whereas the initial unmarried status was the independent variable. For the marriage selection effects, initial poor SRH as the independent variable and follow-up unmarried status as the dependent variable had considered.

Results

Examining the marital protection hypothesis, the initial unmarried status (OR: 2.14; CI at 95%: 1.17, 3.92) was associated with the followed-up SRH transition from good to poor between 2007 and 2015 for young men, while initial unmarried status was linked with a lower likelihood of stable good SRH and a higher likelihood of stable poor SRH status across all age categories among women. Focusing on the marriage selection hypothesis, among young men, a significant association exists between the initial poor SRH and departure in marital status from married to unmarried. Young women with initial poor SRH (OR: 0.68; CI at 95%: 0.40, 1.00) had lower odds of stable married. In comparison, women with initially poor SRH, irrespective of age, were more likely to have higher odds of being stably unmarried.

Conclusion

Marriage indeed protects health. There are also shreds of evidence on health-selected marital status in India. Taken together, the aspect of marital protection or marriage selection is gender and age-specific in India. The findings contribute to a more comprehensive understanding of the relationship between marriage and health, which may have significant implications for health-related public policies aimed at unmarried women.

Health status and the Great Recession. Evidence from electronic health records

We investigate the impact of the Great Recession in Italy on the incidence of chronic diseases using new individual longitudinal data from Electronic Health Records. We exploit the exogenous shock in the economic conditions occurred in 2008 to estimate heterogeneous effects of an unprecedented rise in local unemployment rates in an individual fixed-effects model. Our results document that harsh economic downturns have a negative long-lasting effect on cardiovascular disease and a temporary effect on depression. This effect is heterogeneous across gender, increases with age and is stronger right before the retirement age. An important policy recommendation emerging from this study is that prolonged economic downturns constitute an additional external risk for individual health and not a temporary benefit.

Racial/ethnic health disparities among children with special health care needs in Boston, Massachusetts

BACKGROUND

Little is known about the factors that contribute to racial/ethnic disparities among children with special health care needs (CSHCN).

OBJECTIVE

To quantify the contributions of determinants of racial/ethnic disparities in health and health care among CSHCN in Boston, Massachusetts.

METHODS

A sample of 326 Black, Latino, and white CSHCN was drawn from the Boston Survey of Children's Health, a city-wide representative sample of children. The study implemented Oaxaca-Blinder-style decomposition techniques to examine the relative contributions of health resources and child-, family-, and neighborhood-level factors to disparities in four outcomes: health status, barriers to medical care, oral health status, and utilization of preventive dental care.

RESULTS

White CSHCN had a greater likelihood of having very good/excellent health and oral health and were less likely to experience barriers to care than Black CSHCN. Compositional differences on predictors explained 63%, 98%, and 80% of these gradients, respectively. Group variation in household income, family structure, neighborhood support, and exposure to adverse childhood experiences accounted for significant portions of the Black-white gaps in health and access. White CSHCN were also more likely to have very good/excellent health and oral health compared to Latino CSHCN. Differences on predictors accounted for about 86% and 80% of these gaps, respectively. Household income, adverse childhood experiences, and household language emerged as significant determinants of Latino-white disparities.

CONCLUSIONS

Racial/ethnic health disparities among CSHCN are explained by relatively few determinants. Several of the contributing factors that emerged from the analysis and could be targeted by public health and policy interventions.

Predictive capacity of self-rated health on all-cause mortality in Spain: differences across sex, age and educational level

BACKGROUND

Published evidence on self-rated health's capacity to predict mortality and its variability across subpopulations lacks consistency. Our objective is to evaluate this predictive association and whether/how it varies by sex, age and educational attainment at the population level in Spain.

METHODS

Data came from a prospective longitudinal study based on 42 645 individuals aged ≥15 years who participated in the 2011-2012 and 2014 Spanish Health Surveys. Median follow-up time for mortality was 5.4 years. Cox proportional hazards models adjusted for sociodemographic, lifestyle and chronic disease variables were used to estimate the predictive capacity of self-rated health on mortality.

RESULTS

Self-rated health was associated with mortality with a dose-response effect (p value for linear trend <0.001). Compared with respondents who rated their health as very good, those rating it as very poor presented an HR of 3.33 (95% CI 2.50 to 4.44). Suboptimal self-rated health was a stronger predictor of mortality among 15-44 year-olds (HR 2.87; 95% CI 1.59 to 5.18), compared with the estimate for 45-64 year-olds (HR 1.86; 95% CI 1.45 to 2.39) (p value for interaction=0.001) and for those 65 and older (HR 1.51; 95% CI 1.36 to 1.68) (p value for interaction <0.001). Regarding educational attainment, the association was stronger for individuals with university studies (HR 2.51; 95% CI 1.67 to 3.76) than for those with only primary or no studies (HR 1.31; 95% CI 1.17 to 1.48) (p value for interaction=0.010). No statistically significant differences were observed between men and women.

CONCLUSIONS

Self-rated health may be considered a good predictor of all-cause mortality in the population of Spain, although the magnitude of this predictive association varies by age and educational level.

Self-rated health, socioeconomic status and all-cause mortality in Chinese middle-aged and elderly adults

Our study aims to investigate the association between SRH and all-cause mortality, and to investigate whether the SRH-mortality association varies across different socioeconomic status (SES) groups among middle-aged and older Chinese adults. We used data from China Health and Retirement Longitudinal Study (CHARLS), including 11,762 participants for the final analysis. Cox proportional hazards regression was conducted to investigate the association between SRH status and subsequent mortality. There were 724 death events occurred. The results were shown that fair/poor SRH participants tend to die than better SRH peers (HR 1.46, 95% CI 1.12–1.91). The association only occurred in those with rural residency (HR 1.46, 95% CI 1.05–2.04), those who were literate (HR 1.65, 95% CI 1.17–2.33), those with above-average household income (HR 1.95, 95% CI 1.15–3.29) and those working in agriculture and below (HR 1.38, 95% CI 1.02–1.88). In conclusion, worse SRH may be a predictor of all-cause mortality among middle-aged and elderly Chinese, especially in people with rural residency, literacy, above-average household income and working in agriculture and below.

A general pattern of health erosion in the United States? An examination of self-reported health status from 1997 - 2018

Purpose

Recent research has found a general pattern of health erosion in self-assessed pain and allostatic load among adults in the United States (US). It remains to be determined if self-reported health status, hereafter SRH, also follows this pattern. The aim of this study was to examine whether a general pattern of health erosion is found in SRH among adults in the United States (US).

Methods

Data from the National Health Interview Survey 1997-2018 were used to study sex, educational attainment, and racial/ethnic patterns in SRH by age, period and cohort among adults in the US. The analytic sample consisted of respondents aged 18 years or older at the moment of interview with valid information in the age, sex, education, race/ethnicity and health status question (n = 669,501). Estimates for the percent population reporting poor/fair health were produced by age, period and cohort to study trends in health status by sex, educational attainment and race/ethnicity. All estimates were weighted to account for complex survey design.

Results

No discernible pattern of health erosion, or improvement, is observed in the age, period or cohort analyses of the percent of the population reporting poor/fair SRH by sex, educational attainment or race/ethnicity.

Conclusions

The analysis indicates that self-reported health does not follows the general pattern of health erosion found in self-assessed pain and allostatic load in the US. The percent of the population reporting poor/fair health status has remained relatively stable between 1997 and 2018. Further research is required to determine whether self-reported health is an appropriate metric to track population health in the US.

Perceived healthcare discrimination and well-being among older adults in the United States and Brazil

Despite well-documented evidence illustrating the relationship between discrimination and health, less is known about the influence of unfair treatment when receiving medical care. Moreover, our current knowledge of cross-national and racial variations in healthcare discrimination is limited in aging populations. This article addresses these gaps using two harmonized data sets of aging populations to clarify the relationship between healthcare discrimination and health in the United States and Brazil. We use nationally representative, harmonized data from the Health and Retirement Study in the United States and the Brazilian Longitudinal Study of Aging to examine and compare perceived discrimination in the healthcare setting and its relationship to self-rated health, depression diagnosis, and depressive symptoms across national contexts. Using Poisson regression models and population attributable risk percent estimates, we found that aging adults reporting healthcare discrimination were at higher risk of poor self-rated health, diagnosed depression, and depressive symptoms. Our results also suggest that reducing perceived healthcare discrimination may contribute to improved self-rated health and mental well-being in later life across racialized societies. In two comparative settings, we highlight the differential impact of healthcare discrimination on self-rated health and depression. We describe the implications of our study's findings for national public health strategies focused on eliminating discrimination in the healthcare setting, particularly among aging countries.

Self-Rated Health Among Italian Immigrants Living in Norway: A Cross-Sectional Study

Background

Most studies on immigrant health focus on immigrant groups coming from extra-European and/or low-income countries. Little attention is given to self-rated health (SRH) in the context EU/EEA migration. To know more about health among European immigrants can provide new insights related to social determinants of health in the migration context. Using the case of Italian immigrants in Norway, the aim of this study was to (i) examine the levels of SRH among Italian immigrants in Norway as compared with the Norwegian and the Italian population, (ii) examine the extent to which the Italian immigrant perceived that moving to Norway had a positive or negative impact on their SRH; and (iii) identify the most important factors predicting SRH among Italian immigrants in Norway.

Methods

A cross-sectional survey was conducted among adult Italian immigrants in Norway (n = 321). To enhance the sample's representativeness, the original dataset was oversampled to match the proportion of key sociodemographic characteristics of the reference population using the ADASYN method (oversampled n = 531). A one-sample Chi-squared was performed to compare the Italian immigrants' SRH with figures on the Norwegian and Italian populations according to Eurostat statistics. A machine-learning approach was used to identify the most important predictors of SRH among Italian immigrants.

Results

Most of the respondents (69%) rated their SRH as "good" or "very good". This figure was not significantly different with the Norwegian population, nor to the Italians living in Italy. A slight majority (55%) perceived that their health would have been the same if they continued living in Italy, while 23% perceived a negative impact. The machine-learning model selected 17 variables as relevant in predicting SRH. Among these, Age, Food habits, and Years of permanence in Norway were the variables with the highest level of importance, followed by Trust in people, Educational level, and Health literacy.

Conclusions

Italian immigrants in Norway can be considered as part of a "new mobility" of high educated people. SHR is shaped by several interconnected factors. Although this study relates specifically to Italian immigrants, the findings may be extended to other immigrant populations in similar contexts.

Associations of occupational and leisure-time physical activity with self-rated health in Korea

Recent findings have suggested that not all physical activity (PA) types improve health and that the health effects of occupational PA (OPA) and leisure-time PA (LTPA) can be different. However, few studies have been reported the association of OPA and LTPA with self-rated health (SRH). Therefore, we aimed to examine the association between different PA domains and general health and the impact of LTPA on the relationship between health and OPA. In total, 33440 adults from the Korea National Health and Nutrition Examination Survey 2014-2019 were analyzed in September 2021. SRH was dichotomized into "poor" and "good." Sedentary behavior (SB) was evaluated by measuring the daily sitting time. Multiple logistic regression was used to investigate the relationship of SRH with OPA, LTPA, and SB, stratified by LTPA to identify its impact on the relationship. In the fully adjusted model, OPA was found to increase the risk of poor SRH, while LTPA was found to lower the risk. In those who did not engage in LTPA, OPA and poor SRH were significantly associated. Poor SRH was not significantly associated with OPA in those who engaged in LTPA. SB was also associated with poor SRH, independent of LTPA. To improve health, it is important to promote LTPA and reduce OPA and SB. In particular, for workers with a higher level of OPA, additional LTPA should be introduced to prevent SRH from worsening.

Assessing the Validity of Self-rated Health Across Ethnic Groups: Implications for Health Disparities Research

OBJECTIVES

This study examines the association between morbidity (i.e., chronic health conditions) and self-rated health (SRH) with the aim of testing the within-group and across-group validity of SRH across nine ethnic groups: non-Latinx White, Mexican, Puerto Rican, Cuban, African American, Afro-Caribbean, Chinese, Filipino, and Vietnamese Americans. In addition, we assess whether acculturation (i.e., nativity, years of US residency, language of interview) and health-related factors (e.g., mental disorder) account for ethnic distinctions in SRH.

DESIGN

Data are from the National Survey of American Life (NSAL) and the National Latino and Asian American Study (NLAAS) (N = 8338). Weighted proportions and means for SRH and chronic conditions are reported. Ordered logistic regression analysis is used to determine ethnic group patterns in SRH.

RESULTS

Despite evidence of within-group validity of SRH for each ethnic group, our results seriously challenge the across-group validity of SRH. For example, Chinese and Vietnamese respondents report lower SRH despite having fewer chronic conditions relative to non-Latinx Whites. Moreover, Mexican Americans report fewer chronic health problems but lower SRH compared to non-Latinx Whites. Acculturation factors (e.g., language of interview) partially explain the Mexican-White difference in SRH. Among Chinese Americans, completing an interview in English is associated with higher SRH relative to those who completed an interview in Chinese.

CONCLUSION

These findings have implications for health disparities research that uses SRH as the dependent measure. Studies that compare the health profiles of diverse ethnic groups should use the SRH measure with caution, as SRH does not align with ethnic patterns of morbidity.

Measuring older people's socioeconomic position: a scoping review of studies of self-rated health, health service and social care use

Background

The challenges of measuring socioeconomic position in older populations were first set out two decades ago. However, the question of how best to measure older people’s socioeconomic position remains pertinent as populations age and health inequalities widen.

Methods

A scoping review aimed to identify and appraise measures of socioeconomic position used in studies of health inequalities in older populations in high-income countries. Medline, Scopus, EMBASE, HMIC and references lists of systematic reviews were searched for observational studies of socioeconomic health inequalities in adults aged 60 years and over, published between 2000 and 2020. A narrative synthesis was conducted.

Findings

One-hundred and thirty-eight studies were included; 20 approaches to measuring socioeconomic position were identified. Few studies considered which pathways the chosen measures of socioeconomic position intended to capture. The validity of subjective socioeconomic position measures, and measures that assume shared income and educational capital, should be verified in older populations. Incomplete financial data risk under-representation of some older groups when missing data are socially patterned. Older study samples were largely homogeneous on measures of housing tenure, and to a lesser extent, measures of educational attainment. Measures that use only two response categories risk missing subtle differences in older people’s socioeconomic circumstances.

Conclusion

Poor choice of measures of socioeconomic position risk underestimating the size of health inequalities in older populations. Choice of measures should be shaped by considerations of theory, context and response categories that detect subtle, yet important, inequalities. Further evidence is required to ascertain the validity of some measures identified in this review.

Low fruit and vegetable intake is associated with poor self-rated health in the Czech part of the HAPIEE study

Background: Although fruits and vegetables are considered a pillar of healthy eating, previous evidence suggests that their consumption in Eastern European countries is low, and their association with health outcomes has rarely been researched in this region. Aim: To examine the effect of fruit and vegetable intake on self-rated health (SRH) in the Czech arm of the Health, Alcohol and Psychosocial factors in Eastern Europe prospective cohort study. Methods: Dietary data on fruit and vegetable intake was measured at baseline using food frequency questionnaires, and SRH from the second wave was chosen as the main outcome. The relationship between fruit and vegetable intake and SRH was analysed using multivariable ordinal regression. Results: A total of 4255 persons aged 45-69, in good and very good SRH at baseline were included in the longitudinal analysis, with a median follow-up time of 3.7 years. In the second wave, 218 (5.1%) individuals reported poor or very poor SRH. In the fully adjusted model, individuals in the lowest fruit and vegetable intake quartile had higher odds of poor SRH compared to those in the highest quartile (OR = 1.24, 95% CI: 1.01-1.52). When examined separately, the results were similar: for vegetables (OR = 1.25, 95% CI: 1.03-1.51) and fruit (OR = 1.18, 95% CI: 0.97-1.44). Conclusion: The observed longitudinal association suggests that low fruit and vegetable intake is associated with poor SRH in the Czech Republic. Considering almost half of our sample reported less than the daily recommended intake of 400 grams of fruits and vegetables, higher consumption should be supported.

Accuracy of perceived glaucoma risk by patients in a clinical setting

Objective

To determine whether patients attending the ophthalmology department underestimate their glaucoma risks.

Method

We conducted a cross-sectional survey with a final study population of 1203 individuals from two medical centers in Taiwan during January 1–June 30, 2019. The “High concern” group was defined as the set of patients who rated themselves as having low risk but who had been rated by physicians as having medium or high risk of developing glaucoma over the next year.

Results

Approximately 12% of the respondents belonged to the “High concern” group. For those with education at the college level or higher, the interaction term was estimated to be 0.294 (95% CI = 0.136–0.634). Marginal effect calculations revealed significant sex-based differences in the effect of knowledge at specific age intervals.

Conclusions

A considerable proportion of patients attending the ophthalmology department underestimate their glaucoma risks. Misjudgment of glaucoma risks can lead to delays in seeking of medical attention. Glaucoma education should be designed according to each patient’s education level and sex, as its effect is not consistent across different education and sex clusters.

The Association of Interpersonal Relationships and Social Services with the Self-Rated Health of Spanish Homelessness

Understanding the specific factors associated with poor health is critical to improve the health of homeless people. This study aimed to analyze the influence of personal variables, interpersonal relationships, and the influence of social services on the health of homeless people. A secondary analysis was applied to cross-sectional data from a sample of 1382 homeless people living in the Basque Country (Spain) (75.69% male). Multinomial logistic regression modelling was used to analyze the relationship between health and personal variables, interpersonal variables, perceived help and use of the social services. Relationships with the family, using a day center, and a sufficient and high perceived help of the social services were significant factors associated with good health. On the other hand, spending the day alone or using mental and health care services are associated with poor health. In the same way, the longer a person has been homeless, the worse their expected state of health is. Addressing housing exclusion, promoting interpersonal relationships, using a day center, and developing the use and perceived helpfulness of social services stand out as key factors in improving health status. Social policies are usually focused on housing. However, this paper also highlights the relevance of developing interpersonal relationships and using day centers to improve homeless people’s health.

Adolescent developmental assets and longitudinal weight status and psychosocial health outcomes: Exploratory analysis from a youth cohort study in Taiwan

BACKGROUNDS

Asset-based youth development has been proposed to be associated with health behaviors and psychological well-being in adolescents. This study aims to extend the current knowledge regarding the effects of positive youth development on weight status and psychosocial health outcomes in young adulthood using a large representative longitudinal sample.

METHODS

Data were retrieved from the Taiwan Youth Project that comprised a longitudinal cohort of adolescents (N = 2688) surveyed at grades 7, 8, 9, and 12, and at age 22. Principal component analysis was used to construct developmental asset scores based on 35 items selected from the relevant questions at wave 1. Outcomes were standardized scores of body mass index, self-rated healthiness and happiness, depressive symptomology and deviant behaviors in the subsequent waves. Generalized estimating equation analysis was applied to assess the impact of developmental assets on these repeatedly measured outcome variables.

RESULTS

As compared to those with the highest quintile level of developmental assets, individuals with the lowest quintile level were more likely to rate themselves unhealthy (β = 0.33 [95% confidence interval 0.26, 0.40]) and unhappy (β = 0.47 [0.41, 0.54]) and report more depressive symptomatology (β = 4.18 [3.35, 5.01]) and deviant behaviors (β = 0.63 [0.44, 0.81]). No association was found between body mass index and developmental asset scores.

CONCLUSION

The results concluded a longitudinal association between adolescent developmental assets and psychological and behavioral health outcomes. Further research may be required to investigate whether positive youth development could be translated into long-term benefits in adult physical conditions, such as obesity.

Trajectories of middle-aged and elderly people's chronic diseases Disability Adjusted Life Years (DALYs): cohort, socio-economic status and gender disparities

BACKGROUND

The accelerated aging trend brought great chronic diseases burdens. Disabled Adjusted Life Years (DALYs) is a novel way to measure the chronic diseases burden. This study aimed to explore the cohort, socioeconomic status (SES), and gender disparities of the DALYs trajectories.

METHODS

A total of 15,062 participants (55,740 observations) comes from China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018. Mixed growth curve model was adopted to predict the DALYS trajectories in 45-90 years old people influenced by different birth cohorts and SES.

RESULTS

We find significant cohort, SES (resident place, education level and income) disparities differences in the chronic diseases DALYs. For individuals of earlier cohort, DALYs are developed in a late age but grow fast with age but reversed for most recent cohorts. Living in urban, having higher SES level will decrease the growth rate with age, but converges for most recent cohorts. Meanwhile, DALYs disparities of resident place and education level show gender differentials that those for female are narrowed across cohort but for male are not.

CONCLUSIONS

The cohort effects on chronic diseases DALYs are accumulated with China's unique social, and political settings. There are large inequalities in early experiences, SES and DALYs. Efforts of reducing these inequalities must focus on the lower SES individuals and those living in rural areas, which greatly benefit individuals from recent cohorts.

[Self-perceived health in Spanish and Portuguese young seniors after the great recession according to the European Health Survey: A cross-sectional study]

OBJECTIVE

The aim of this study is to describe self-perceived health (SPH) in Spanish and Portuguese population aged between 65 and 74years old and to analyze other associated factors measured in the European Health Interview Survey (EHIS) in 2014.

DESIGN

Retrospective secondary data analysis from EHIS 2014.

SETTING

Community based.

PARTICIPANTS

Young seniors, people aged 65-74years old surveyed and with available data from two countries.

MAIN MEASUREMENTS

For each country and sex, SPH, sociodemographic variables, clinical chronic conditions, lifestyles and utilization of health care resources were described. A multiple logistic regression (very good or good SPH versus remaining levels) with robust estimators was used to assess the country effect adjusted by sociodemographic factors, clinical factors and/or lifestyles.

RESULTS

Good SPH showed variation by country (52.9% Spain vs. 19% Portugal; P<.001) and gender (44% men vs. 31.3% women; P<.001). Both countries had high prevalence of multimorbidity (64.7% Spain vs. 76.3% Portugal; P<.001) and the distribution of chronic diseases was similar with the only exception of depression (13.2% Spain vs. 20.3% Portugal; P<.001). Regarding individual factors related with good SPH we found Spanish nationality (OR: 4.52; 95%CI: 4.05-5.04), male gender (OR: 1.10; 95%CI: 1.101-2.21), education level, completing primary school (OR: 1.28; 95%CI: 1.24-1.31) or achieving tertiary level (OR: 2.43; 95%CI: 1.14-5.17) and physical activity of two or more days per week (OR: 1.87; 95%CI: 1.39-2.5). Factors with a negative impact on SPH were multimorbidity (OR: 0.19; 95%CI: 0.12-0.31) and depression (OR: 0.32; 95%CI: 0.25-0.41).

DISCUSSION

Good SPH is higher in Spanish young seniors compared to Portuguese. Having higher level of education achieved and practicing regular physical exercise were two most important factors increasing good SPH.

What do time-use patterns tell us about the validity of self-reported health?

OBJECTIVE

This short communication investigates the usefulness of time-use measures to validate subjective health measures such as self-reported health (SRH). It does this by examining time-use patterns and SRH among middle-age adults in the United States distinguished by race/ethnicity and with additional attention to differences in responses based on language of interview for Hispanics.

METHODS

Data for this study come from the 2013-2016 American Time Use Survey. We calculated average time-use for personal care; housework; paid work; leisure; volunteering/travel; caregiving; and education for every racial/ethnic group differentiating by SRH for 27,063 adults aged 25-64 years. A series of ANOVAs were computed to assess differences in time-use by SRH.

RESULTS

Non-Hispanic whites and non-Hispanic Blacks who reported poor/fair SRH spent more time in personal care and leisure, and less time in paid work, volunteering/travel, caregiving and education, in comparison to those who reported Excellent/Very Good/Good SRH. Among Hispanics, differences by SRH were found for personal care, paid work, leisure and volunteering/travel. Hispanics who answered in English displayed partially similar patterns in SRH found for non-Hispanic whites and Blacks. Hispanics who answered in Spanish demonstrated differences in SRH in the areas of paid work, leisure and education, diverging from the other groups.

CONCLUSIONS

Time-use differences by health status are consistent between non-Hispanic whites, non-Hispanic blacks, but not so for Hispanics. To some extent, Hispanics who answered in English have more comparable patterns to non-Hispanic whites and non-Hispanic Blacks than Spanish respondents. Caution should be exercised when self-reported health measures are used to compare diverse samples collected with surveys that are administered in different languages.

Trajectories of Subjective Health: Testing Longitudinal Models for Self-rated Health From Adolescence to Midlife

Self-rated health (SRH) is ubiquitous in population health research. It is one of the few consistent health measures in longitudinal studies. Yet, extant research offers little guidance on its longitudinal trajectory. The literature on SRH suggests several possibilities, including SRH as (1) a more fixed, longer-term view of past, present, and anticipated health; (2) a spontaneous assessment at the time of the survey; (3) a result of lagged effects from prior responses; (4) a function of life course processes; and (5) a combination of the preceding. Different perspectives suggest different longitudinal models, but evidence is lacking about which model best captures SRH trajectory. Using data from the National Longitudinal Study of Adolescent to Adult Health and the National Longitudinal Survey of Youth, we employ structural equation modeling to correct for measurement error and identify the best-fitting, theoretically guided models describing SRH trajectories. Results support a hybrid model that combines the lagged effect of SRH with the enduring perspectives, fitted with a type of autoregressive latent trajectory (ALT) model. This model structure consistently outperforms other commonly used models and underscores the importance of accounting for lagged effects combined with time-invariant effects in longitudinal studies of SRH. Interestingly, comparisons of this latent, time-invariant autoregressive model across gender and racial/ethnic groups suggest that there are differences in starting points but less variability in SRH trajectories from early life into adulthood.

The value of general health perception in health equity research: A community-based cohort study of long-term mortality risk (Finnmark cohort study 1987-2017)

Background

General health perception as measured by self-rated health (SRH) is an individual's synthesis of personal overall health and has value in its own right. In addition, this subjective perspective has a unique predictive power of subsequent mortality and adds valuable information not captured by objective measures. We studied the relationship between SRH and subsequent mortality to demonstrate how simple self-ratings can enhance our understanding of health inequities.

Methods

Data from a population-based survey conducted in Finnmark 1987/1988 were linked to the Norwegian Cause of Death Registry for information on all deaths by the end of 2017. We used Cox proportional hazard regression modelling to estimate the relative effects of all-cause mortality separately for sex and age (30–49 and 50–62 years) with stepwise adjustment for socio-demographics and various other health status and behavioural measures.

Results

The age-adjusted power of mortality prediction of SRH was strong (most pronounced in the youngest age-group) but markedly attenuated by other factors. Education inequality in mortality was most substantial in the youngest age-group, which might partly be due to a combination of selective mortality and historical changes in health inequality. In comparison, educational inequality in SRH was clearly pronounced regardless of age. Work disability pension appeared as the common key factor affecting the mortality prediction of SRH and educational inequity for both subsequent mortality and SRH.

Conclusion

SRH adds unique information to our understanding of health inequities. The consistency in shared predictors of educational inequity concerning both mortality and SRH underscores the correspondence of these measures. In addition to predicting the fatal effects of social selection mechanisms, SRH adds non-fatal effects and seems less prone to selective mortality. The results are relevant to approaches in health equity research and have important policy implications.

•

Self-rated health yielded robust age adjusted mortality predictions.

•

Self-rated health adds unique information to our understanding of health inequities.

•

Educational inequity in mortality is extensive, but it narrows with age, which can be explained by selective mortality and historical changes.

•

Measures to reduce preventable workforce exclusions can be effective for achieving or maintaining health equity.

Evaluation of general body temperament and uterine dystemperament in amenorrhoea: a cross-sectional analytical study

OBJECTIVES

Amenorrhoea in women of reproductive age may be an indication of an undiagnosed and chronic condition. The concept of temperament is a fundamental component of health preservation and diagnosis of various disease conditions including amenorrhoea in Unani medicine. Dystemperament is the commonest cause of various diseases. Therefore, general body temperament and uterine dystemperament in amenorrhoea was determined.

METHODS

A prospective, single-centre, cross-sectional observational study from June to November 2019 was conducted in 80 patients of reproductive age with amenorrhoea ≥60 days. Validated questionnaire for the assessment of women's general body temperament and clinical features of uterine dystemperament was used. The data were analysed by appropriate statistical analysis.

RESULTS

The age of patients with amenorrhoea ranged from 14 to 50 years. The most prevalent general body temperament was cold (57.5%) and wet (60%). Cold and wet general temperament was more common at the age of 21-30 years (30 and 36.25%), 60-90 days of amenorrhoea (33.75 and 32.5%) and body mass index (BMI) ≥25 kg/m² (47.5 and 50%). The most prevalent uterine dystemperament was cold and dry (95%). A significant correlation between general temperament with age, amenorrhoea and BMI >23 kg/m² was noted. Moreover, the cold temperament of the body had a significant correlation with cold uterine temperament (r=0.864, p<0.001).

CONCLUSIONS

This study corroborated the claim of Unani scholars that cold and wet general and uterine temperament is more common in amenorrhoea and obesity. However, amenorrhoea can also occur in normal and other temperaments.

Health status among NEET adolescents and young adults in the United States, 2016-2018

Adolescents and young adults not employed or in education/training (NEET) could be at higher risk of adverse health outcomes. Approximately 4.6 million Americans aged between 16 and 24 fall in this group. However, differences in health between NEET and non-NEET population remain unaddressed. This study examines the association of NEET status and poor/fair self-reported health status (SRH), among adolescents and young adults in the United States. Data for this study come from the 2016–2018 National Survey on Drug Use and Health (NSDUH). Our analytical sample consisted of 53,690 respondents. We used logistic regression models to investigate the association between NEET and health status in the United States, while controlling for potential covariates. Approximately 14% of our analytical sample was classified as NEET. NEET report poor/fair health status at higher rates than their counterparts who remained in school and/or had a job (11.30% vs. 5.62%). The NEET population was older, had a higher proportion of non-Hispanic Blacks, engaged in more smoking but in less alcohol drinking than non-NEET. In our initial model, NEET were more likely report poor/fair SRH than their non-NEET counterparts (OR = 2.14; p < 0.001). This difference remains strong when demographic and socioeconomic characteristics are accounted for in our empirical models (OR = 1.93, p < 0.001). In our fully specified model, which accounts for health behaviors, NEET continue to have higher odds of reporting poor/fair SRH (OR = 1.77, p < 0.001). Our analyses suggest that NEET populations report worse health than non-NEETs. The health of this population may improve if interventions to reinsert them into either education or employment are effectively deployed.

•

Approximately 14% of the population aged 16 to 25 are not employed or participating in education/training activities (NEET).

•

The NEET population report worse health status than their non-NEET peers.

•

NEETs report worse health even when accounting for demographic and socioeconomic characteristics and metropolitan residence.

The utility of self-rated health in population surveys: the role of bodyweight

Background

Self-rated health (SRH) is one of the most commonly used summary measures of overall health and well-being available to population scientists due to its ease of administration in large-scale surveys and to its efficacy in predicting mortality. This paper assesses the extent to which SRH is affected by its placement before or after questions about bodyweight on a survey, and whether differences in placement on the questionnaire affects SRH’s predictive validity.

Methods

I assessed the validity of SRH in predicting the risk of mortality by comparing outcomes of sample members who were asked to rate their health before reporting on their bodyweight (the control group) and sample members who were asked to rate their health after reporting on their bodyweight (the treatment group). Both the control and treatment group were randomly assigned via an experiment administered as a module in a nationally representative sample of adults in the USA in 2019 (N = 2523).

Results

The odds of reporting a more favorable appraisal of health are 30% lower for sample members who were in the treatment group when compared with the control group. Additionally, the SRH of treatment group members is significantly associated with their risk of mortality, while the SRH of control group members is not.

Conclusion

The findings from this study suggest that for researchers to maximize the utility of SRH, closer attention needs to be paid to the context of the survey within which it asked. SRH is highly sensitive to the questions that precede it, and this sensitivity may in turn mischaracterize the true health of the population that the survey is intending to measure.

Subjective health in adolescence: Comparing the reliability of contemporaneous, retrospective, and proxy reports of overall health

Self-rated health (SRH) is one of the most important social science measures of health. Yet its measurement properties remain poorly understood. Most studies ignore the measurement error in SRH despite the bias resulting from even random measurement error. Our goal is to estimate the measurement reliability of SRH in contemporaneous, retrospective, and proxy indicators. We use the National Longitudinal Study of Adolescent to Adult Health to estimate the reliability of SRH relative to proxy assessments and respondents' recollections of past health. Even the best indicators - contemporaneous self-reports - have a modest reliability of ~0.6; retrospective and proxy assessments fare much worse, with reliability less than 0.2. Moreover, not correcting for measurement error in SRH leads to a ~20-40% reduction in its correlation with other measures of health. Researchers should be skeptical of analyses that treat these subjective reports as explanatory variables and fail to take account of their substantial measurement error.

Does the Union Make Us Strong? Labor-Union Membership, Self-Rated Health, and Mental Illness: A Parametric G-Formula Approach

Union members enjoy better wages and benefits and greater power than nonmembers, which can improve health. However, the longitudinal union-health relationship remains uncertain, partially because of healthy-worker bias, which cannot be addressed without high-quality data and methods that account for exposure-confounder feedback and structural nonpositivity. Applying one such method, the parametric g-formula, to US-based Panel Study of Income Dynamics data, we analyzed the longitudinal relationships between union membership, poor/fair self-rated health (SRH), and moderate mental illness (Kessler 6-item score of ≥5). The SRH analyses included 16,719 respondents followed from 1985-2017, while the mental-illness analyses included 5,813 respondents followed from 2001-2017. Using the parametric g-formula, we contrasted cumulative incidence of the outcomes under 2 scenarios, one in which we set all employed-person-years to union-member employed-person-years (union scenario), and one in which we set no employed-person-years to union-member employed-person-years (nonunion scenario). We also examined whether the contrast varied by sex, sex and race, and sex and education. Overall, the union scenario was not associated with reduced incidence of poor/fair SRH (relative risk = 1.01, 95% confidence interval (CI): 0.95, 1.09; risk difference = 0.01, 95% CI: -0.03, 0.04) or moderate mental illness (relative risk = 1.02, 95% CI: 0.92, 1.12; risk difference = 0.01, 95% CI: -0.04, 0.06) relative to the nonunion scenario. These associations largely did not vary by subgroup.

The longitudinal relation between depressive symptoms and change in self-rated health: A nationwide cohort study

OBJECTIVE

This study aimed to prospectively assess the relationship between depressive symptoms and change in self-rated health (SRH) in middle-aged and elderly Chinese adults.

METHODS

We used data from the China Health and Retirement Longitudinal Study (CHARLS). The final analysis included 8169 participants (≥45 years old) and a multinomial logistic regression model was used to assess the association between baseline depression and follow-up change in SRH.

RESULTS

Taking no change in SRH as the reference, depressive symptoms at baseline were positively associated with a 2-year decline in SRH (OR: 1.38, 95% CI: 1.15-1.65) and negatively associated with a 2-year improvement in SRH (OR: 0.74, 95% CI: 0.63-0.85). Over a 4-year period, the OR (95% CI) values increased to 1.41 (1.19-1.67) and decreased to 0.69 (0.59-0.80) for decline and improvement in SRH, respectively. In stratified analyses, the association between depression and 2- or 4-year decline/improvement in SRH persisted in all sex and age subgroups.

CONCLUSIONS

Baseline depression is an independent predictor of change in SRH among Chinese people aged 45 and above. Early monitoring and management of depressive symptoms may be worthwhile to maintain and improve SRH in the middle-aged and elderly population.

Neighborhood Age Composition and Self-Rated Health: Findings from a Nationally Representative Study

Neighborhood age composition is an understudied area. Furthermore, existing empirical and conceptual work is conflicting, with some scholarship-indicating neighborhoods with older adults are beneficial and other scholarship suggesting it can be detrimental. Combining data from 7,197 older adults from the first wave (2011) of the National Health & Aging Trends Study and census tract data from the National Neighborhood Change Database, the purposes of our study were to: 1) identify the characteristics of neighborhoods experiencing different types of changes in age composition, and 2) examine the association between neighborhood age composition and self-rated health. Findings indicate that neighborhoods experiencing Concentration (where the number of older adults are declining but their percentage of the total population are increasing), the majority of which are in urban areas, have less aggregate economic resources, more indicators of neighborhood disorder, and less access to services and supports. Regression models also suggest older adults living in Concentration neighborhoods reported lower self-rated health compared to those living in the other three neighborhood types. Findings point to the importance of considering neighborhood age composition when targeting interventions and resources, and the potential consequences of being stuck in place in a neighborhood that does not meet elders' needs.

Socioeconomic status, well-being and mortality: a comprehensive life course analysis of panel data, Germany, 1984-2016

BACKGROUND

This study seeks to explore potential causal mechanisms involved in the observed associations between several socioeconomic status (SES) indicators, well-being and mortality, by taking a life course perspective focusing on (i) the trajectory of income and domain-specific well-being indicators, (ii) the influence of different SES indicators on well-being and mortality, (iii) the interactions between those trajectories, and (iv) the associations of the income and domain-specific well-being trajectories with all-cause mortality.

METHODS

Socioeconomic status is operationalised by net household income, education, employment and marital status. Well-being is measured with two indicators: life satisfaction and satisfaction with health. Data from the German Socio-Economic Panel, collected between 1984 and 2016 and comprising more than 55,000 individuals, are analysed by means of longitudinal k-means cluster analysis, simultaneous equation systems and parametric time-to-death regressions.

RESULTS

The analyses indicate the presence of large reciprocal effects of the trajectories of income and well-being on each other. However, the results suggest that well-being has a larger influence on income than the opposite, namely, income on well-being. The mortality analysis, on the other hand, revealed that the history of satisfaction with health is a much stronger predictor of longevity than the individual's income history. Mortality risk was found lower among married individuals and those with tertiary education. In contrast, unemployment was associated with lower income and well-being levels. The findings provide support to the notion that education is a superior SES indicator than income in the investigation of the social determinants of well-being and mortality.

CONCLUSION

The present study provides evidence of large reciprocal effects of income and well-being and emphasises the importance of taking a life course approach in the investigation of the social determinants of health. Several SES indicators and both well-being indicators were found to be highly predictive of all-cause mortality and indicate the presence of cumulative effects related to one's income and well-being trajectories.

Association between objectively measured sleep duration and physical function in community-dwelling older adults

STUDY OBJECTIVES

The aim of this research was to investigate the relationships between objectively measured sleep duration and physical function in older adults.

METHODS

We recruited community-dwelling older adults aged ≥ 60 years old in Taipei City, Taiwan. Sleep duration was measured with accelerometers and recorded as the total hours of sleep per night for each participant. The following physical functions were assessed: 1) grip strength (measured by handgrip dynamometer), 2) balance (1-leg standing test), 3) lower body strength (5-timed chair stand), 4) basic mobility (timed up and go test), 5) gait speed (5-m walk test). The relationships between sleep duration and physical function outcomes were analyzed using generalized additive models, controlling for objectively measured sedentary behavior and moderate-to-vigorous physical activity, and other sociodemographic variables.

RESULTS

A total of 121 older adults (men = 28.9%; mean age = 70.0 ± 5.0 years) was included in this study. A positive association of sleep duration with grip strength was found after adjusting for covariates (P = .005). No significant associations were observed between sleep duration and the other physical function outcomes.

CONCLUSIONS

For older adults, lengthening their sleep duration may be helpful to enhance the grip strength. This result has implications for improving their health by targeting better performance in specific physical functions. Further studies of sleep duration and physical function among older adults should investigate the underlying mechanisms.
