Race and health profiles in the United States: an examination of the social gradient through the 2009 CHIS adult survey

The relationships between resilience and child health behaviors in a national dataset

BACKGROUND

Resilience mechanisms at the individual, family, and environmental levels may improve health outcomes despite potentially harmful stress exposure partly through the practice of positive health behaviors.

METHODS

We performed a secondary analysis of 2016-2021 National Survey of Children's Health data to assess the relationships between three resilience domains - child, family, neighborhood - and six health behaviors using multiple regression models adjusted for the other resilience domain(s) and potential confounders.

RESULTS

Analysis revealed significant associations between each resilience domain and multiple health behaviors in a total weighted analytic sample of 70,156,540 children. For each outcome, the odds of better health behaviors were highest with high resilience in all possible domains. For example, among children ages 0-5 years, the adjusted odds of having "good quality" vs. "poor quality" sleep for those with "high" resilience in all domains were 2.21 times higher (95% CI 1.78, 2.63) than for those with "low" resilience in all domains.

CONCLUSIONS

This line of research may help to inform the design of resilience and health behavior promotion interventions by targeting multiple socio-ecological domains of influence to improve health and development outcomes in children exposed to experiences or sources of potential stress.

IMPACT

This study assessed the associations between three socio-ecological resilience domains (child, family, and neighborhood) and six child and family health behaviors in a national dataset. Resilience exists within multiple socio-ecological levels and supports healthy functioning despite experiencing stress. Studies in adults and limited pediatric sub-populations show associations between resilience and health behaviors, which in turn influence numerous health outcomes. Resilience at three levels of socio-ecological levels was found to be associated with the performance of multiple child and family health behaviors in a nationally representative general pediatric population. These findings have important implications for child and family health promotion efforts.

How Education Shapes Indigenous Health Inequalities in the USA and Mexico

Indigenous peoples around the world face significant health disparities relative to the dominant groups in their countries, yet the magnitude and patterns of health disparities vary across countries. We use data from the National Health Interview Survey and Mexican Family Life Survey to examine the health of Indigenous peoples in Mexico and American Indians and Alaska Natives in the USA and to evaluate how they fare relative to the majority populations in their countries (non-Indigenous Mexicans and non-Hispanic Whites, respectively). We assess disparities in self-rated health and activity limitations, with a focus on how Indigenous health disparities intersect with educational gradients in health. Regression analyses reveal three primary findings. First, Indigenous health disparities are larger in the USA than in Mexico. Second, differences in educational attainment account for most of the differences between Indigenous and non-Indigenous populations in Mexico, but less than half in the USA. Third, in both countries, health is moderated by educational attainment such that between-group disparities are largest at the highest levels of education. However, for Indigenous Mexicans there is a "cross-over" in which Indigenous Mexicans report better health at the lowest level of education. Overall, this study finds a weak relationship between education and Indigenous health, and raises the question about the validity of using traditional measures of SES in Indigenous contexts.

Comorbidity Burden in Psoriasis Patients with Skin of Color

Background

Psoriasis is a chronic disease with increased risk of numerous comorbidities. Known differences exist regarding treatment outcomes for psoriasis patients with skin of color (SOC). However, factors contributing to these differences are relatively unknown.

Objectives

This study aims to compare the comorbidity burden in SOC psoriasis patients vs. White patients, as measured by the Charlson Comorbidity Index (CCI) score.

Methods

We utilized the National Ambulatory Medical Care Survey (NAMCS) to identify visits for adult psoriasis patients occurring in the years 2002-2016 and 2018. The CCI was used to objectively measure comorbidity burden. Patients were identified by race, and SOC was defined as any reported race besides White Only. A multiple linear regression was run to compare the CCI among adult psoriasis patients based on race and ethnicity, controlling for age, sex, insurance status, and geographic region.

Results

A total of 39,176,928 weighted visits were analyzed. Compared to White patients, patients with SOC did not have statistically significant differences in comorbidity burden, as measured by CCI score (p=0.073 for Black/African American Only vs. White Only, p=0.073 for American Indian/Alaska Native Only vs. White Only, p=0.435 for Asian Only vs. White Only, p=0.403 for Native Hawaiian/Pacific Islander Only vs. White Only, p=0.195 for Other vs. White Only).

Conclusion

Patients with SOC were not found to have differences in comorbidity burden compared to White patients. These results highlight that social factors such as socioeconomic status and access to healthcare may contribute more directly to psoriasis treatment outcomes than patient race.

Genetics of Alzheimer's Disease in the African American Population

Black/African American (AA) individuals have a higher risk of Alzheimer's disease (AD) than White non-Hispanic persons of European ancestry (EUR) for reasons that may include economic disparities, cardiovascular health, quality of education, and biases in the methods used to diagnose AD. AD is also heritable, and some of the differences in risk may be due to genetics. Many AD-associated variants have been identified by candidate gene studies, genome-wide association studies (GWAS), and genome-sequencing studies. However, most of these studies have been performed using EUR cohorts. In this paper, we review the genetics of AD and AD-related traits in AA individuals. Importantly, studies of genetic risk factors in AA cohorts can elucidate the molecular mechanisms underlying AD risk in AA and other populations. In fact, such studies are essential to enable reliable precision medicine approaches in persons with considerable African ancestry. Furthermore, genetic studies of AA cohorts allow exploration of the ways the impact of genes can vary by ancestry, culture, and economic and environmental disparities. They have yielded important gains in our knowledge of AD genetics, and increasing AA individual representation within genetic studies should remain a priority for inclusive genetic study design.

Adolescent peer struggles predict accelerated epigenetic aging in midlife

This study examined struggles to establish autonomy and relatedness with peers in adolescence and early adulthood as predictors of advanced epigenetic aging assessed at age 30. Participants (N = 154; 67 male and 87 female) were observed repeatedly, along with close friends and romantic partners, from ages 13 through 29. Observed difficulty establishing close friendships characterized by mutual autonomy and relatedness from ages 13 to 18, an interview-assessed attachment state of mind lacking autonomy and valuing of attachment at 24, and self-reported difficulties in social integration across adolescence and adulthood were all linked to greater epigenetic age at 30, after accounting for chronological age, gender, race, and income. Analyses assessing the unique and combined effects of these factors, along with lifetime history of cigarette smoking, indicated that each of these factors, except for adult social integration, contributed uniquely to explaining epigenetic age acceleration. Results are interpreted as evidence that the adolescent preoccupation with peer relationships may be highly functional given the relevance of such relationships to long-term physical outcomes.

Who Has Active Lifestyles? Sociodemographic and Personality Correlates of Activity Diversity in Two Samples of Adults

OBJECTIVES

Activity diversity-an index of active lifestyles that captures variety (number) and evenness (consistency) in activity engagement-is known to support health in adulthood. However, less is known who has higher or lower activity diversity, information that helps identify individuals who may be at greater risk for poor health. This article examined sociodemographic characteristics and Big Five personality traits that may be associated with activity diversity.

METHODS

We used 2 independent project samples (nsample1 = 2,699; nsample2 = 301). Sample 1 included U.S. national adults in a wide age range (25-84). Sample 2 included U.S. community-dwelling older adults (age = 65-89). Each study asked about different types of activity engagement using surveys. The activity diversity index was calculated in each sample, using Shannon's entropy method.

RESULTS

In Sample 1, older adults, women, non-Hispanic White individuals, married/partnered individuals, and those with higher education and fewer functional limitations had higher activity diversity. Additionally, higher conscientiousness, higher extraversion, and lower neuroticism were each associated with higher activity diversity after controlling for sociodemographic factors. Extraversion and neuroticism remained significant in the younger group (age < 65) of Sample 1, but only extraversion was a significant factor associated with activity diversity in the older group (age ≥ 65). The results in the older group were generally replicated in Sample 2, such that higher extraversion in older adults was consistently associated with higher activity diversity independent of the strong correlates of sex, education, and functional limitations.

DISCUSSION

Findings were discussed in terms of age-specific associations between sociodemographic and personality characteristics and activity diversity.

The impact of social determinants of health on obesity and diabetes disparities among Latino communities in Southern California

BACKGROUND

Social determinants of health (SDoH) describe the complex network of circumstances that impact an individual before birth and across the lifespan. SDoH contextualize factors in a community that are associated with chronic disease risk and certain health disparities. The main objective of this study was to explore the impact of SDoH on the prevalence of obesity and diabetes, and whether these factors explain disparities in these health outcomes among Latinos in Southern California.

METHODS

We utilized three composite indices that encompass different SDoH: the Healthy Places Index (HPI), Social Vulnerability Index (SVI), and CalEnviroScreen (CES). Univariate linear regression models explored the associations between index scores with adult obesity, adult diabetes, and childhood obesity.

RESULTS

Communities with lower HPI scores were associated with higher prevalence of metabolic disease and a greater proportion of Latino residents. Cities in the lowest decile of HPI scores had 71% of the population identifying as Latino compared to 12% in the highest decile. HPI scores explained 61% of the variability in adult obesity (p < 0.001), 41% of the variability in childhood obesity (p < 0.001), and 47% of the variability in adult diabetes (p < 0.001). Similar results were observed when examining SVI and CES with these health outcomes.

CONCLUSIONS

These results suggest that Latinos in Southern California live in communities with adverse SDoH and face a greater burden of adult obesity, diabetes, and childhood obesity.

Student loans, physical and mental health, and health care use and delay in college

Objective: Determine relationships between college students' student loan presence and self-rated physical and mental health, major medical problems, mental health conditions, physical, dental, and mental health care visits and delays, and medication use and reductions. Participants: A total of 3,248 undergraduates at two regional public U.S. universities, surveyed Spring 2017. Methods: OLS and Logistic regression. Results: Loan presence was related to significantly worse self-rated physical and mental health and more major medical problems, but not to mental health conditions, or physical or mental health medication use. Respondents with loans were less likely to visit the dentist and more likely to report delaying medical, dental, and mental health care, and reducing medication use to save money. Conclusions: Results provide evidence of health and health care use divides among college students by loan presence.

Increasing psychological distress among Californians from 2013 to 2020: Race/ethnic differences

The influence of the COVID-19 pandemic on mental health is of mounting concern to population-health researchers. While early reports indicated increases in mental health problems, noticeably absent from these studies is how mental health has changed in 2020 compared to previous years (2013-2019) and whether such trends vary by race/ethnicity. The present study used repeated cross-sectional data from the California Health Interview Survey (n ​= ​168,216) to systematically document trends in psychological distress scores (Kessler-6 scale; K6) and severe psychological distress scores (K6; 13+) from 2013 to 2020 and by race/ethnicity over the same period. Among all Californians we find that the reported average psychological distress scores increased by 22% between 2013 and 2020. Reported severe psychological distress scores increased 61% from 2013 to 2020. These increases were largely concentrated in the years 2017-2020. Increases in psychological distress were also especially pronounced among non-Latino/a White Californians (29% increase in K6 from 2013 to 2020), Latino/a Californians (14% increase in K6 from 2013 to 2020), and Asian Californians (35% increase in K6 from 2013 to 2020). Multiple and logistic regression models that accounted for sociodemographic and behavioral health covariates echoed these findings. Future research should continue to investigate secular trends in mental health that coincided with the COVID-19 pandemic and carefully situate the shifts into broader temporal perspective.

Race/ethnicity, gender and the SES gradient in BMI: The diminishing returns of SES for racial/ethnic minorities

Using the 2013-2016 data from the National Health and Nutrition Examination Survey (NHANES), this study uses the case of obesity to examine whether and to what extent racial and ethnic minorities experience fewer benefits from higher SES relative to their white counterparts. Study results provide support for the diminishing returns in health hypothesis and add an intersectional dimension to this perspective by uncovering stark gendered racial/ethnic disparities in BMI. Specifically, research findings demonstrate that higher income and education is associated with lower BMI among white but not black or Mexican American adults. The most substantial decrease in BMI associated with increase in individual-level SES was observed among white women. Taken together, empirical evidence from this study underscores difficulty in overcoming adverse health effects of lower ascribed status (i.e. gender or race/ethnicity) even with attainment of higher achieved social status (i.e. educational attainment or income) and offers promising avenues for future research on identifying complex hierarchies that shape population health outcomes.

Determinants of perceived health and unmet healthcare needs in universal healthcare systems with high gender equality

Background

Patient attitudes about health and healthcare have emerged as important outcomes to assess in clinical studies. Gender is increasingly recognized as an intersectional social construct that may influence health. Our objective was to determine potential sex differences in self-reported overall health and access to healthcare and whether those differences are influenced by individual social factors in two relatively similar countries.

Methods

Two public health surveys from countries with high gender equality (measured by UN GII) and universal healthcare systems, Canada (CCHS2014, n = 57,041) and Austria (AT-HIS2014, n = 15,212), were analysed. Perceived health was assessed on a scale of 1 (very bad) to 4 (very good) and perceived unmet healthcare needs was reported as a dichotomous variable (yes/no). Interactions between sex and social determinants (i.e. employment, education level, immigration and marital status) on outcomes were analysed.

Results

Individuals in both countries reported high perceived health (Scoring > 2, 85.0% in Canada, 79.9% in Austria) and a low percentage reported unmet healthcare needs (4.6% in Canada, 10.7% in Austria). In both countries, sex and several social factors were associated with high perceived health, and a sex-by-marital status interaction was observed, with a greater negative impact of divorce for men. Female sex was positively associated with unmet care needs in both countries, and sex-by-social factors interactions were only detected in Canada.

Conclusions

The intersection of sex and social factors in influencing patient-relevant outcomes varies even among countries with similar healthcare and high gender equality.

Who engages in the arts in the United States? A comparison of several types of engagement using data from The General Social Survey

BACKGROUND

Engaging in the arts is a health-related behavior that may be influenced by social inequalities. While it is generally accepted that there is a social gradient in traditional arts and cultural activities, such as attending classical music performances and museums, previous studies of arts engagement in the US have not adequately investigated whether similar demographic and socioeconomic factors are related to other forms of arts engagement.

METHODS

Using cross-sectional data from the General Social Survey (GSS) in the US, we examined which demographic, socioeconomic, residential, and health factors were associated with attendance at arts events, participation in arts activities, membership of creative groups, and being interested in (but not attending) arts events. We combined data from 1993 to 2016 in four analytical samples with a sample size of 8684 for arts events, 4372 for arts activities, 4268 for creative groups, and 2061 for interested non-attendees. Data were analysed using logistic regression.

RESULTS

More education was associated with increased levels of all types of arts engagement. Parental education demonstrated a similar association. Being female, compared to male, was also consistently associated with higher levels of engagement. Attendance at arts events was lower in participants with lower income and social class, poorer health, and those living in less urban areas. However, these factors were not associated with participation in arts activities or creative groups or being an interested non-attendee.

CONCLUSIONS

Overall, we found evidence for a social gradient in attendance at arts events, which was not as pronounced in participation in arts activities or creative groups or interest in arts events. Given the many benefits of engagement in the arts for education, health, and wider welfare, our findings demonstrate the importance of identifying factors to reduce barriers to participation in the arts across all groups in society.

Longitudinal data reveal strong genetic and weak non-genetic components of ethnicity-dependent blood DNA methylation levels

Epigenetic architecture is influenced by genetic and environmental factors, but little is known about their relative contributions or longitudinal dynamics. Here, we studied DNA methylation (DNAm) at over 750,000 CpG sites in mononuclear blood cells collected at birth and age 7 from 196 children of primarily self-reported Black and Hispanic ethnicities to study race-associated DNAm patterns. We developed a novel Bayesian method for high-dimensional longitudinal data and showed that race-associated DNAm patterns at birth and age 7 are nearly identical. Additionally, we estimated that up to 51% of all self-reported race-associated CpGs had race-dependent DNAm levels that were mediated through local genotype and, quite surprisingly, found that genetic factors explained an overwhelming majority of the variation in DNAm levels at other, previously identified, environmentally-associated CpGs. These results indicate that race-associated blood DNAm patterns in particular, and blood DNAm levels in general, are primarily driven by genetic factors, and are not as sensitive to environmental exposures as previously suggested, at least during the first 7 years of life.

Data spanning three decades illustrate racial disparities in likelihood of obesity

Obesity rates have risen significantly in recent decades, with underprivileged Americans associated with higher rates of the condition. Risks associated with obesity, furthermore, appear unequally distributed across different racial/ethnic groups, according to the literature. The present study examined racial disparities in obesity as a function of socioeconomic factors, using a sample of American adults from a 32-year longitudinal study. We accounted for the time factor as we evaluated obesity's associations with selected socioeconomic factors; we also examined race/ethnicity's moderating role in obesity-socioeconomic status associations over time. We used data from the National Longitudinal Survey of Youth (NLSY) to obtain a final sample of 118,749 person-waves for analysis. A subsample of person-waves numbering 65,702 represented data from White respondents; one numbering 31,618 represented data from Black respondents; and one numbering 21,429 represented data from Hispanic respondents. Needing to consider repeated measures of the same variables over time, we chose generalized estimated equations (GEE) for use in the data analysis. Speaking generally, the obtained results suggested that for the two smaller subsamples, minority race/ethnicity could have introduced disadvantages that helped explain links between obesity and race/ethnicity. Results also showed that White-Black disparities in obesity have widened slightly in the past three decades, while White-Hispanic disparities have stabilized during the same time period.

Socioeconomic position and the health gradient in Cuba: dimensions and mechanisms

Background

To throw light on the under-researched association between socioeconomic position (SEP) and health in Cuba, this study examined SEP gradients in health and their underlying mechanisms among urban Cuban adults aged 18–65.

Methods

By applying linear regressions to data from the 2010 National Survey on Risk Factors and Chronic Diseases, the analysis explored the SEP-health gradient along three SEP dimensions − education, occupation, and skin colour − using ten health measures: self-reported health (SRH), general and abdominal obesity, hypertension, high glucose, high cholesterol, high triglycerides, low high-density lipoprotein cholesterol, metabolic syndrome, and cumulative risk factors. Regressions also included behaviours and health-related risk perceptions (tobacco and alcohol consumption, diet, physical activity, and risk-related behaviours). It thus investigated the SEP-health gradient and its underlying mechanisms via both behaviours and health-related risk perceptions.

Results

Once controlling for gender, age, marital status, region and provincial dummies, the analysis detected educational gradients in SRH (estimated coefficient [95% CI]: middle-level education = 3.535 [1.329, 5.741], p < 0.01; high-level education = 5.249 [3.050, 7.448], p < 0.01) that are partially explainable by both health-affecting behaviours (tobacco and alcohol consumption, diet, physical and sedentary activity) and risk perceptions. Using objective measures of health, however, it found no SEP-health gradients other than hypertension among people identified as having Black skin color (adjusted for demographic variables, 0.060 [0.018, 0.101], p < 0.01) and high cholesterol among those identified as having Mulatto or Mestizo skin color (adjusted for demographic variables, − 0.066 [− 0.098, − 0.033], p < 0.01).

Conclusions

In terms of objective health measures, the study provides minimal evidence for an SEP-health gradient in Cuba, results primarily attributable to the country’s universal healthcare system − which offers full coverage and access and affordable medications − and its highly developed education system.

Intensive Outpatient Treatment (IOP) of Behavioral Health (BH) Problems: Engagement Factors Predicting Subsequent Service Utilization

The purpose of the study is to 1) better understand patterns of utilization of Intensive Outpatient Treatment (IOP) Programs and Services in the State of Connecticut by adult Medicaid recipients experiencing a serious mental illness, substance use disorder, or co-occurring disorders; and 2) to determine the relationship between the duration of an IOP episode and connection to care rates for higher (i.e., rehospitalization) or lower levels of care following discharge. We hypothesized that the duration of an IOP episode would impact positively in reducing the use of higher levels of care while increasing the use of lower levels of care. In order to examine the frequency and duration of use of Intensive Outpatient (IOP) services by the CT Medicaid population, a two-year timeframe was selected: July 1, 2012 to June 30, 2014. A survival analysis was conducted to assess the risk of readmission to an IOP within 180 days based on demographic and utilization factors including, Age (in years on date of discharge), Race and Ethnicity, Gender, Homeless Status (at least one day in CY 2013), and Engagement Group (Intent to Treat, Early Termination, Minimally Adequate Dosage, & Target or More). To better understand the patterns of utilization associated with Adult IOP services, the average length of stay, number of treatment days, and average number of treatment days per week were explored. The number of unique individuals who were part of this analysis is 11,473, of which 2050 were mental health IOP utilizers (18%), 4598 were co-occurring IOP utilizers (40%), and 4825 (42%) were substance use IOP utilizers. For the total population, the average length of stay (ALOS) in days was 42 and the average number of treatment days attended per week was 2.5, for an average of 15 treatment days per episode of care. Among the IOP Cohorts, the Mental Health Cohort had the longest ALOS at 44.15 days, an average of 2.34 days of service per week, for an average of 14.76 days of IOP service per episode of care. The Substance Use Cohort had the shortest ALOS at 41.33 days, but had the highest intensity of services per week at 2.71 for an average of 16 days of service per episode of care. The Co-Occurring Cohort presented an ALOS of 41.74 days, an average of 2.32 services per week and an average of 13.83 sessions per episode. Overall there is evidence supporting an association between the number of days of care and protection from hospitalization, up to a certain number of days of care or number of days in IOP. Above the Minimally Adequate Dosage, the IOP protection factor seems to reach a plateau. This means that after 16 days of care, the chances of hospitalization remain the same regardless of the additional days provided.

Evidence to Improve Physical Activity among Medically Underserved Older adults: A Scoping Review

BACKGROUND AND OBJECTIVES

Participation in leisure physical activity (PA) and engagement in PA interventions among older adults is influenced by socioeconomic status (SES), race/ethnicity, and environment. However, studies of PA for medically underserved older adults have not yet been systematically evaluated. The objective of this study is to map the nature and extent of research conducted on PA participation, interventions, and components of effective leisure PA programs for medically underserved older adults.

RESEARCH DESIGN AND METHODS

The five-stage approach was used to conduct this scoping review. We searched PubMed, CINAHL, and Cochrane Library for peer-reviewed studies published between 2006 and 2016. Data extracted from selected studies included study population, study type, purpose of intent, evidence level, barriers to PA participation, and components of PA intervention.

RESULTS

Three hundred and ninety-two articles were identified, and 60 studies were included in the final data charting. Existing literature showed that most studies remained descriptive in nature, and few intervention studies have achieved a high level of evidence. Among 21 intervention studies, only 4 were explicitly conducted for older adults. Culturally adapted materials, race/ethnicity-specific barriers and facilitators, and form of intervention were important components for intervention programs.

DISCUSSION AND IMPLICATIONS

Findings indicate that more studies are needed to reduce health disparities related to PA participation for medically underserved older adults. Intervention components such as race/ethnicity-relevant barriers and facilitators and culturally sensitive materials are also needed for PA interventions targeting underserved older adults in order to provide evidence for best practices.

Subjective Social Status and Financial Hardship: Associations of Alternative Indicators of Socioeconomic Status with Problem Drinking in Asian Americans and Latinos

Background: Prior research shows inconsistent associations between socioeconomic status (SES) and alcohol outcomes, particularly for immigrant populations. Conventional markers of SES may not fully capture how social position affects health in these groups. Objective: We examine: (1) the associations of two alternative indicators, subjective social status (SSS) and financial hardship, with problem drinking outcomes, heavy episodic drinking (HED) and alcohol use disorder (AUD), for Asian Americans and Latinos; and (2) moderation of these relationships by educational level and nativity status. Methods: Multiple logistic regression modeling was performed using nationally-representative Asian American (n = 2,095) and Latino samples (n = 2,554) from the National Latino and Asian American Study. Age, gender, nativity, individual-level SES (income and education), unfair treatment, racial discrimination, and social support were adjusted. Results: Financial hardship was independently associated with AUD in both Asians and Latinos. Lower SSS was associated with increased AUD risk among individuals with college degrees or with US nativity in both populations. The association between financial hardship and HED was positive for US-born Latinos and foreign-born Asians, and negative for foreign-born Latinos. Conclusions: SSS and financial hardship are indicators of SES that may have particular relevance for immigrant health, independently of education and income, with SSS particularly meaningful for AUD in the more conventionally advantaged subgroups. There may be underlying processes affecting Asian and other Latino subgroups with similar socioeconomic and nativity profiles and exposing them to common risk/protective factors of AUD.

Racial/Ethnic Variations in Clustered Risk Behaviors in the U.S

INTRODUCTION

Alcohol misuse, cigarette smoking, poor diet, and physical inactivity, known as the "big four" contributors to chronic conditions and mortality, typically co-occur or cluster together, with their synergistic effect more detrimental to health than their cumulative individual effects. Little research has been reported on race/ethnicity-specific analyses of the clustering of these behaviors in the U.S. This study identified clustered risk behaviors among whites, blacks, and Hispanics and examined whether unhealthy clusters were associated with lower SES (assessed by education level and family income) and poor health status.

METHODS

A nationally representative sample of U.S. adults aged 30-69 years (n=9,761) from the 2010 and 2015 National Alcohol Surveys was used to perform latent class analysis and multinomial and logistic regression modeling in 2018-2019. Obesity was used as a proxy for unhealthy diet.

RESULTS

Three lifestyle classes were identified in each group. The relatively healthy lifestyle class was identified among whites and Hispanics. The nonsmoking and low risky drinking class among blacks, though showing a healthier lifestyle than the other 2 classes, still had relatively high prevalence of inactivity and obesity. The inactive and obese class was found in all 3 groups. Also identified were the smoking and risky drinking class among whites; the smoking and inactive class among blacks; and the smoking, inactive, and risky drinking class among Hispanics. For all 3 groups, unhealthy lifestyle classes mostly were associated with lower SES. Unhealthy lifestyle classes were also associated with poorer health status.

CONCLUSIONS

Multi-behavior interventions are warranted to address inactivity and obesity in all 3 groups and unhealthy clusters involving smoking in each group.

Associations of Asian Ethnicity and Parental Education with Overweight in Asian American Children and Adolescents: An Analysis of 2011-2016 National Health and Nutrition Examination Surveys

Objectives Asian Americans are highly diverse in cultural, socioeconomic, and health conditions. We aimed to identify socioeconomic and cultural profiles of subgroups of Asian American children at high risk of obesity or overweight to inform targeted interventions. Methods A sample of 841 Asian American children and adolescents ages 6-19 from the 2011-2016 National Health and Nutrition Examination Survey was used. Multivariable logistic regression modeling was conducted. Analyses were also stratified by age (6-11 vs. 12-19). Key variables of interest were Asian ethnicity (Chinese, Korean/Japanese, Filipino, South Asian, and Southeast Asian) and parental educational level. Models adjusted for age, gender, nativity status, parental nativity status, and health insurance coverage. Results Filipino (AOR 2.79; 95% CI 1.30-6.00), Japanese/Korean (AOR 2.55; 95% CI 1.21-5.38), Southeast Asian (AOR 2.54; 95% CI 1.63-3.94), and South Asian (AOR 2.10; 95% CI 1.01-4.36) children ages 6-19 had higher odds of being obese/overweight than Chinese. Filipino (AOR 3.24; 95% CI 1.11-9.49) and Southeast Asian (AOR 2.47; 95% CI 1.22-5.01) ethnicities were associated with higher risk of obesity/overweight in adolescents ages 12-19. Having a parent with a 4-year college or advanced degree was inversely associated with obesity/overweight in US-born Asian adolescents (AOR 0.34; 95% CI 0.14-0.78). Conclusions for Practice Asian American children and adolescents in some Asian ethnic subgroups may be at higher risk of obesity/overweight than in others. Higher parental education level appears to protect US-born Asian American adolescents from being obese/overweight. Multi-sectoral efforts are needed to better understand and address sociocultural processes that increase childhood obesity/overweight in high-risk Asian subgroups.

Mental health status and dietary intake among California adults: a population-based survey

California Health Interview Survey (2005-2015) data were used to examine the association between dietary intake frequencies and mental health - Kessler-6 scores categorised as no/low (NLPD), moderate (MPD) or serious psychological distress (SPD). The 245,891 surveys represented 27.7 million adults annually, with 13.2% having MPD and 3.7% SPD. Survey-adjusted regression adjusting for gender, age, race, education, poverty, marital status, BMI, geography and year found MPD and SPD associated with lower consumption of fruits (adjusted odds ratio 0.79 and 0.65, respectively), vegetables (AOR 0.81 and 0.68), and increased consumption of French fries (AOR 1.24, 1.30), fast food (AOR 1.32, 1.27), soda (AOR 1.23, 1.26) and variance-adjusted daily teaspoons of sugar (coefficients 3.05, 4.21), all p-values less than 0.001. In this large population-based sample, moderate and SPD were independently associated with unhealthy diet. Targeted public health interventions could focus on young adults and those with less than 12 years of education.

Factors Associated With Physical Performance Measures in a Multiethnic Cohort of Older Adults

Objective: To explore the association between ethnicity, sociodemographic, health, and lifestyle factors, and physical performance (PP) in ethnically diverse community-dwelling older adults from one geographic area. Method: We used multivariable linear regression to identify factors associated with upper (grip strength [GS], arm curls [AC]) and lower (chair stands [CS]) body strength and mobility (gait speed [GSp]) in 577 older adults (mean age 74 ± 8; 104 African American, 142 Afro-Caribbean, 123 Hispanic, and 208 European American) from South Florida. Results: Worse mental health was negatively associated with CS in African Americans and AC in Hispanics. Older age and higher body mass index (BMI) was associated with slower GSp in all except in Hispanics. Higher physical activity was associated with higher upper body strength in Hispanics and better mobility in African Americans and Afro-Caribbeans, but not in European Americans. Conclusion: Studies with large multiethnic cohorts are needed to further our understanding of ethnic differences in PP, which will help in tailoring interventions and recognizing unmet needs for health and social services.

Obesity trend in the United States and economic intervention options to change it: A simulation study linking ecological epidemiology and system dynamics modeling

OBJECTIVES

To study the country-level dynamics and influences between population weight status and socio-economic distribution (employment status and family income) in the US and to project the potential impacts of socio-economic-based intervention options on obesity prevalence.

STUDY DESIGN

Ecological study and simulation.

METHODS

Using the longitudinal data from the 2001-2011 Medical Expenditure Panel Survey (N = 88,453 adults), we built and calibrated a system dynamics model (SDM) capturing the feedback loops between body weight status and socio-economic status distribution and simulated the effects of employment- and income-based intervention options.

RESULTS

The SDM-based simulation projected rising overweight/obesity prevalence in the US in the future. Improving people's income from lower to middle-income group would help control the rising prevalence, while only creating jobs for the unemployed did not show such effect.

CONCLUSIONS

Improving people from low- to middle-income levels may be effective, instead of solely improving reemployment rate, in curbing the rising obesity trend in the US adult population. This study indicates the value of the SDM as a virtual laboratory to evaluate complex distributive phenomena of the interplay between population health and economy.

Associations of overweight/obesity and socioeconomic status with hypertension prevalence across racial and ethnic groups

Racial/ethnic disparities in the prevalence of diagnosed hypertension are persistent but may be partially explained by racial/ethnic differences in weight category and neighborhood socioeconomic status. The authors compared hypertension prevalence rates among 4 060 585 adults with overweight or obesity across 10 healthcare systems by weight category and neighborhood education level in geographically and racially diverse individuals. Data were obtained from electronic health records. Hypertension was defined as at least two outpatient visits or one inpatient hospitalization with a coded diagnosis. Logistic regression, adjusted for age, sex, and site, with two-way interactions between race/ethnicity and weight category or neighborhood education, was used to examine the association between hypertension and race/ethnicity, with whites as the reference. Results documented that odds ratios for hypertension prevalence were greater for blacks, American Indians/Alaskan Natives, Asians, and Native Hawaiians/other Pacific Islanders compared with whites and lower for Hispanics in similar weight categories and neighborhood education levels. Although two-way interactions were statistically significant, the magnitude of the odds of hypertension compared with whites did not substantially vary across weight or neighborhood education. Hypertension odds were almost double relative to whites for blacks and Native Hawaiians/other Pacific Islanders across most weight categories and all neighborhood education levels. Odds of hypertension were about 50% greater for Asians relative to whites across weight categories. Results suggest that other factors might be associated with racial/ethnic disparities in hypertension. More research is needed to understand the many factors that may contribute to variation in diagnosed hypertension across racial/ethnic groups with overweight or obesity.

Race disparities in cardiovascular disease risk factors within socioeconomic status strata

PURPOSE

Racial differences in socioeconomic status (SES) explain some, but not all, of racial disparities in cardiovascular disease (CVD) risk. To address this, race disparities among higher SES individuals need to be assessed. The purpose of this study was to assess whether racial disparities in CVD risk factors differ by SES levels.

METHODS

Data from the National Health and Nutritional Examination Survey 2007-2014 were used to calculate racial differences in hypertension, high cholesterol, diabetes, and obesity. Interactions between race and SES were assessed.

RESULTS

African Americans had higher odds of hypertension (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.72-2.09), diabetes (OR, 1.66; 95% CI, 1.33-2.07), and obesity (OR, 1.64; 95% CI, 1.46-1.83) than whites. Significant interactions between race and income greater than or equal to $100,000 were observed for obesity (OR, 1.55; 95% CI, 1.24-1.94) and between race and education (college graduate or more; OR, 1.58; 95% CI, 1.16-2.15). Disparities in diabetes were observed in the highest SES groups, but not among those in the lowest SES groups.

CONCLUSIONS

Race disparities in some CVD risk factors varied by SES levels. Results suggest that race disparities in obesity are larger among those with income greater than or equal to $100,000 and who are college graduates. It is possible that African Americans experience fewer health-related benefits of increased income and education levels compared with whites.

Differential methylation between ethnic sub-groups reflects the effect of genetic ancestry and environmental exposures

Populations are often divided categorically into distinct racial/ethnic groups based on social rather than biological constructs. Genetic ancestry has been suggested as an alternative to this categorization. Herein, we typed over 450,000 CpG sites in whole blood of 573 individuals of diverse Hispanic origin who also had high-density genotype data. We found that both self-identified ethnicity and genetically determined ancestry were each significantly associated with methylation levels at 916 and 194 CpGs, respectively, and that shared genomic ancestry accounted for a median of 75.7% (IQR 45.8% to 92%) of the variance in methylation associated with ethnicity. There was a significant enrichment (p=4.2×10-64) of ethnicity-associated sites amongst loci previously associated environmental exposures, particularly maternal smoking during pregnancy. We conclude that differential methylation between ethnic groups is partially explained by the shared genetic ancestry but that environmental factors not captured by ancestry significantly contribute to variation in methylation.

Community-identified strategies to increase physical activity during elementary school recess on an American Indian reservation: A pilot study

The aim of this study was to determine the effect of an 8-week recess intervention on physical activity levels in children attending elementary school on an American Indian reservation during fall 2013. Physical activity was measured with direct observation in three zones on the playground. Lines were painted on existing pavement in zone 1. Zone 2 had permanent playground equipment and was unchanged. Zone 3 contained fields where bi-weekly facilitators led activities and provided equipment. Pre- to post-changes during recess in sedentary, moderate physical activity, moderate-to-vigorous, and vigorous physical activities were compared within zones. Females physical activity increased in Zone 1 (moderate: 100% increase; moderate-to-vigorous: 83%; vigorous: 74%, p < 0.01 for all) and Zone 3 (moderate: 54% increase, p < 0.01; moderate-to-vigorous: 48%, p < 0.01; vigorous: 40%, p < 0.05). Male sedentary activity decreased in Zone 2 (161%, p < 0.01). Physical activity changes in Zone 3 were not dependent upon the presence of a facilitator. Simple and low-cost strategies were effective at increasing recess physical activity in females. The findings also suggest that providing children games that are led by a facilitator is not necessary to increase physical activity as long as proper equipment is provided.

A comparison study on the prevalence of obesity and its associated factors among city, township and rural area adults in China

OBJECTIVES

To explore the association of dietary behaviour factors on obesity among city, township and rural area adults.

SETTING

A stratified cluster sampling technique was employed in the present cross-sectional study. On the basis of socioeconomic characteristics, two cities, two townships and two residential villages were randomly selected where the investigation was conducted.

PARTICIPANTS

A total of 1770 city residents, 2071 town residents and 1736 rural area residents participated in this survey.

PRIMARY AND SECONDARY OUTCOME MEASURES

Dietary data were collected through interviews with each household member. Anthropometric values were measured. Participants with a body mass index (BMI) of ≥28.0 kg/m(2) were defined as obesity.

RESULTS

The prevalence of obesity was 10.1%, 7.3% and 6.5% among city, township and rural area adults, respectively. Correlation analysis showed that for adults living in cities, the daily intake of rice and its products, wheat flour and its products, light coloured vegetables, pickled vegetables, nut, pork and sauce was positively correlated with BMI (r=0.112, 0.084, 0.109, 0.129, 0.077, 0.078, 0.125, p<0.05), while the daily intake of tubers, dried beans, milk and dairy products was negatively correlated with BMI (r=-0.086, -0.078, -0.116, p<0.05). For township residents, the daily intake of vegetable oil, salt, chicken essence, monosodium glutamate and sauce was positively correlated with BMI (r=0.088, 0.091, 0.078, 0.087, 0.189, p<0.05). For rural area residents, the daily intake of pork, fish and shrimp, vegetable oil and salt was positively correlated with BMI (r=0.087, 0.122, 0.093, 0.112, p<0.05), while the daily intake of dark coloured vegetables was negatively correlated with BMI (r=-0.105, p<0.05).

CONCLUSIONS

The prevalence of obesity was higher among city residents than among township and rural area residents. The findings of this study indicate that demographic and dietary factors could be associated with obesity among adults. Healthy dietary behaviour should be promoted and the ongoing monitoring of population nutrition and health status remains crucially important.

Individual- and community-level social gradients of edentulousness

Background

Community-level factors as well as individual-level factors affect individual health. To date, no studies have examined the association between community-level social gradient and edentulousness. The aim of this study was to investigate individual- and community-level social inequalities in edentulousness and to determine any explanatory factors in this association.

Methods

We analyzed the data from the Japan Gerontological Evaluation Study (JAGES). In 2010-2012, 112,123 subjects aged 65 or older responded to the questionnaire survey (response rate = 66.3%). Multilevel logistic regression analysis was applied to determine the association between community-level income and edentulousness after accounting for individual-level income and demographic covariates. Then, we estimated the probability of edentulousness by individual- and community-level incomes after adjusted for covariates.

Results

Of 79,563 valid participants, the prevalence of edentulousness among 39,550 men (49.7%) and 40,013 women (50.3%) were both 13.8%. Living in communities with higher mean incomes and having higher individual-level incomes were significantly associated with a lower risk of edentulousness (odds ratios [ORs] by 10,000 USD increments were 0.37 (95% confidence interval [CI] [0.22-0.63]) for community-level and 0.85 (95% CI [0.84-0.86]) for individual-level income). Individual- and community-level social factors, including density of dental clinics, partially explained the social gradients. However, in the fully adjusted model, both community- and individual-level social gradients of edentulousness remained significant (ORs = 0.43 (95% CI [0.27-0.67]) and 0.90 (95% CI [0.88-0.91]), respectively). One standard deviation changes in community- and individual-level incomes were associated with 0.78 and 0.84 times lower odds of edentulousness, respectively. In addition, compared to men, women living in communities with higher average incomes had a significantly lower risk of edentulousness (p-value for interaction < 0.001).

Conclusions

Individual- and community-level social inequalities in dental health were observed. Public health policies should account for social determinants of oral health when reducing oral health inequalities.
