Ma A, Campbell J, Sanchez A, Sumner S, Ma M. Racial Concordance on Healthcare Use within Hispanic Population Subgroups. J Racial Ethn Health Disparities 2024; 11:2329-2337. [PMID: 37479955 PMCID: PMC11236923 DOI: 10.1007/s40615-023-01700-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 06/20/2023] [Accepted: 06/24/2023] [Indexed: 07/23/2023]
Abstract
OBJECTIVE To examine the association of patient-provider racial and ethnic concordance on healthcare use within Hispanic ethnic subgroups. METHODS We estimate multivariate probit models using data from the Medical Expenditure Panel Survey, the only national data source measuring how patients use and pay for medical care, health insurance, and out-of-pocket spending. We collect and utilize data on preventive care visits, visits for new health problems, and visits for ongoing health problems from survey years 2007-2017 to measure health outcomes. Additionally, we include data on race and ethnicity concordance, non-health-related socioeconomic and demographic factors, health-related characteristics, provider communication characteristics, and provider location characteristics in the analysis. The sample includes 59,158 observations: 74.3% identified as Mexican, 10.6% identified as Puerto Rican, 5.1% identified as Cuban, 4.8% identified as Dominican, and 5.2% classified in the survey as Other Hispanics. Foreign-born respondents comprised 56% of the sample. A total of 8% (4678) of cases in the sample involved Hispanic provider-patient concordance. RESULTS Hispanic patient-provider concordance is statistically significant and positively associated with higher probabilities of seeking preventive care (coef=.211, P<.001), seeking care for a new problem (coef=.208, P<.001), and seeking care for an ongoing problem (coef=.208, P<.001). We also find that the association is not equal across the Hispanic subgroups. The association is lowest for Mexicans in preventive care (coef=.165, P<.001) and new problems (coef=.165, P<.001) and highest for Cubans in preventive care (coef=.256, P<.001) and ongoing problems (coef=.284, P<.001). Results are robust to the interaction of the Hispanic patient-provider concordance for the Hispanic patient categories and being foreign-born. CONCLUSIONS In summary, racial disparities were observed in health utilization within Hispanic subgroups. While Hispanic patient-provider concordance is statistically significant in associating with healthcare utilization, the findings indicate that this association varies across Hispanic subpopulations. The observations suggest the importance of disaggregating Hispanic racial and ethnic categories into more similar cultural or origin groups. Linked with the existence of significant differences in mortality and other health outcomes across Hispanic subgroups, our results have implications for the design of community health promotion activities which should take these differences into account. Studies or community health programs which utilize generalized findings about Hispanic populations overlook differences across subgroups which may be crucial in promoting healthcare utilization.

Abstract
PURPOSE Pediatric obesity disproportionately impacts Hispanic or Latino/a adolescents. Culturally appropriate family-based behavioral initiatives to improve weight status are warranted. The purpose of this research was to determine prevalence rates and identify protective factors associated with having overweight/obesity (body mass index ≥ 85th percentile) to inform Hispanic or Latino/a-targeted behavioral intervention development. DESIGN Secondary data analyses of a population-based statewide survey. SETTING Minnesota public high schools. PARTICIPANTS Male (n = 2,644) and female (n = 2,798) Hispanic or Latino/a 9th and 11th graders (N = 5,442). MEASURES Obesity-related behaviors (meeting fruit and vegetable [F&V] and physical activity [PA] recommendations), family caring, family country/region of origin, and weight status. ANALYSIS Stepwise logistic regression models (F&V, PA), stratified by biological sex, were used to identify protective factors of overweight/obesity. RESULTS The overall prevalence of meeting F&V and PA recommendations was 11.0% and 11.8%, respectively. Meeting F&V recommendations was not protective against overweight/obesity in either sex. Yet, males and females who met PA recommendations had significantly lower odds of having overweight/obesity (p < .05). In F&V and PA models, family caring was protective against overweight/obesity in females (p < .05), and family country/region of origin was protective against overweight/obesity in both sexes (p < .05). CONCLUSION Findings illustrate a need for obesity prevention initiatives for Hispanic or Latino/a youth. More research is needed to understand the protective nature of family caring and country/region of origin.

[PMID: 36510504 PMCID: PMC9738159 DOI: 10.2147/jmdh.s391587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2022] [Accepted: 11/24/2022] [Indexed: 12/09/2022] Open
Abstract
Purpose Osteoporosis is a degenerative disease that affects women and men of all races. We studied the association between body mass index (BMI), rs2908004 polymorphism of the WNT16 gene, and osteoporosis using data from Taiwan Biobank (TWB). Patients and Methods We analyzed data from 10,942 subjects aged 30 to 70. We defined osteoporosis based on a mean T-score of -2.5 and below in the hip. Body mass index was classified following the guidelines of the Health Promotion Administration. Imputation was carried out using the IMPUTE2 (v2.3.1) program. Multiple logistic regression was used for analysis. The odds ratios (ORs) and 95% confidence interval (CI) for osteoporosis were determined. Results In the multivariate regression model, variant rs2908004 had a significant association with osteoporosis. That is, the rs2908004-GA+AA genotype was associated with lower osteoporosis risk than the GG genotype (OR, 0.651; 95% CI = 0.544 to 0.780). Compared to normal-weight, underweight was significantly associated with a higher risk of osteoporosis (OR, 6.517; 95% CI = 4.624 to 9.186) while overweight and obesity were protective (OR, 0.176; 95% CI = 0.140 to 0.221 and 0.057; 95% CI = 0.039 to 0.083, respectively). There was an interaction between rs2908004 and BMI (p = 0.0148). Subgroup analyses (using rs2908004-GG/normal-weight as the reference group) indicated ORs of 7.66 (95% CI = 5.153 to 11.394) in the rs2908004-GG/underweight group and 3.002 (95% CI = 1.509 to 5.974) in the rs2908004-GA+AA/underweight group (95% CI = 1.509 to 5.974). Odds ratios were substantially lower in rs2908004-GG/obese, rs2908004-GG/overweight, GA+AA/normal-weight, rs2908004-GA+AA/overweight, and rs2908004-GA+AA/obese groups, respectively. Conclusion According to our study, underweight was associated with an increased risk of osteoporosis irrespective of WNT16 rs2908004 genotypes, while overweight and obesity were associated with a lower risk.

The impact of sex on blood pressure and anthropometry trajectories from early adulthood in a Nigerian population: insights into women's cardiovascular disease risk across the lifespan. BMC Womens Health 2022; 22:303. [PMID: 35869545 PMCID: PMC9306031 DOI: 10.1186/s12905-022-01888-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Accepted: 07/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Sex disparities in blood pressure and anthropometry may account for differences in cardiovascular (CV) risk burden with advancing age; modulated by ethnic variability. We explored trajectories of blood pressures (BPs) and anthropometric indices with age on the basis of sex in an urban Nigerian population. METHODS We conducted a secondary analysis on data from 5135 participants (aged 16-92 years; 2671(52%) females) from our population-based cross-sectional study of BP profiles. We utilized the WHO STEPS and standardized methods for documenting BPs, body mass index (BMI) and waist circumference (WC). Data was analyzed using Analysis of variance (ANOVA), Spearman correlation analysis and mean difference in variables (with 95% confidence interval). We explored the influence of age and sex on BP profiles and specific anthropometric indices using generalized regression analysis. RESULTS In those aged 15-44 years, males had significantly higher systolic BP (SBP) and pulse pressure (PP). However, mean SBP and PP rose more steeply in females from 25 to 34 years, intersected with that of males from 45 to 54 years and remained consistently higher. Difference in mean BPs (95% Confidence Interval) (comparing < and > 45 years) was higher in females compared to males for SBP (17.4 (15.8 to 19.0) v. 9.2 (7.7 to 10.7), DBP (9.0 (7.9 to 10.1) v. 7.8 (6.7 to 8.9)), and PP (8.4 (7.3 to 9.5) v. 1.4 (0.3 to 2.5)). Females had significantly higher BMI and WC across all age groups (p < 0.001). Age more significantly correlated with BPs, BMI and WC in females. Interaction models revealed that SBP was significantly predicted by age category in females from (15-54 years), while DBP was only significantly predicted by age in the 15-34-year category (p < 0.01). BMI and WC were significantly predicted by age only in the 25-34-year category in females, (p < 0.01). CONCLUSIONS Our population demonstrates sex disparity in trajectories of SBP, PP, BMI and WC with age; with steeper rise in females. There is a need to focus on CV risk reduction in females, starting before, or during early adulthood.

Abstract
Chronic and acute stress may have a detrimental effect on children's physical activity. Research on stress as a predictor of children's physical activity has mostly focused on stress between children, rather than how children's within-day variation in stress may predict physical activity. The current study assessed the within- and between-effects of stress on subsequent physical activity in three different time windows using ecological momentary assessment (EMA) and accelerometry. Children (N = 190; MBaseline Age =10.1±0.9, 53% female, 56% self-identified Hispanic/Latino) completed six semi-annual assessment bursts across three years. During each burst, participants responded to up to seven (weekend) or three (weekday) randomly prompted EMA surveys on smartphones for seven days and wore a waist-worn accelerometer. Multi-level structural equation modeling examined within- and between-subjects effects of stress as a predictor of children's subsequent moderate-to-vigorous physical activity (MVPA) in the 15, 30, and 60 minutes following the EMA prompt. Latent variables were created for within- and between-subjects stress were comprised of three EMA stress items. Higher than average levels of stress (within-subjects) significantly predicted lower MVPA in the subsequent 15, 30 and 60 minutes (ps < .05). Between-subjects stress was not significantly associated with subsequent MVPA (ps > .05). Results indicate that elevated momentary stress predicts less subsequent MVPA. These findings suggest that within-day fluctuations in stress may be a barrier for children engaging in physical activity. Childhood physical activity promotion and interventions should consider the role of children's stress, aim to reduce the stress children experience throughout the day, and incorporate stress coping strategies.

Abstract
To investigate sex and racial/ethnic differences in overweight and obesity in college students. Participants: A nationally representative sample of 319,342 U.S. college students (mean age = 20.4 years; 67.7% female) from Fall 2011 to Spring 2015. Methods: A secondary data analysis of multi-year cross-sectional data was performed. Multiple logistic regression was used to examine factors (e.g. cumulative grade average, year in school, and living place) associated with overweight and obesity determined from BMI calculated by self-reported height and weight. Results: The prevalence of overweight and obesity was significantly higher for both sexes in Spring 2015 than in Fall 2011. Significant differences were found in overweight and obesity by sex and race/ethnicity. Higher adjusted odds ratios for overweight and obesity were observed for men, blacks, and Hispanics (compared to whites). Asians had the lowest adjusted odds of overweight and obesity. Conclusions: Intervention strategies for the prevention and management of overweight and obesity in U.S. college students should consider sex and racial/ethnic inequalities.

Abstract
No research exists on how body mass index (BMI) changes with age over the full life span and social disparities therein. This study aims to fill the gap using an innovative life-course research design and analytic methods to model BMI trajectories from early adolescence to old age across 20th-century birth cohorts and test sociodemographic variation in such trajectories. We conducted the pooled integrative data analysis (IDA) to combine data from four national population-based NIH longitudinal cohort studies that collectively cover multiple stages of the life course (Add Health, MIDUS, ACL, and HRS) and estimate mixed-effects models of age trajectories of BMI for men and women. We examined associations of BMI trajectories with birth cohort, race/ethnicity, parental education, and adult educational attainment. We found higher mean levels of and larger increases in BMI with age across more recent birth cohorts as compared with earlier-born cohorts. Black and Hispanic excesses in BMI compared with Whites were present early in life and persisted at all ages, and, in the case of Black-White disparities, were of larger magnitude for more recent cohorts. Higher parental and adulthood educational attainment were associated with lower levels of BMI at all ages. Women with college-educated parents also experienced less cohort increase in mean BMI. Both race and education disparities in BMI trajectories were larger for women compared with men.

Abstract
Aim We compared the effects of parental education and household income on children's body mass index (BMI) in Hispanic White (HW) and non-Hispanic White (NHW) families. Methods In this cross-sectional study, we borrowed data from the Adolescent Brain Cognitive Development (ABCD) study and analyzed data of 5100 children between the ages of 9 and 10. The independent variables were parental education and household income. The primary outcome was BMI value. Ethnicity was the moderating variable. Confounders were age, sex, and family structure. Three mixed-effects regression models were used for data analysis. Results Overall, higher parental education and household income were associated with lower BMI levels in children. While an interaction was found between ethnicity and parental education, no interaction was noted between ethnicity and household income regarding BMI. The interaction indicated weaker protective effects of high parental education on BMI in HW children than NHW children. Household income showed similar protective effects on children's BMI in HW and NHW families. Conclusion Parental education but not household income loses some of its protective effects on childhood BMI among HW families compared to NHW families. Distal social determinants of health may be more vulnerable to the MDRs (minorities' diminished returns) than proximal ones. As a result, closing the income gap may be a good strategy towards closing the childhood BMI gap between highly educated HW and NHW families. Policies that raise the minimum wage and those that help HW families save money (e.g., earned income tax policies) maybe more promising strategies to eliminate the ethnic gap in BMI than increasing the education level of ethnic minority families.

BACKGROUND Although insufficient physical activity (PA), high sedentary behaviour (SB), and inadequate sleep are fairly common among children, little is known about these behaviours in immigrant children. This systematic review examined the prevalence of PA, SB, and sleep among immigrant children aged 5-17 years around the globe. METHODS Four electronic databases were searched to retrieve the English language peer-reviewed original articles published between 2000 and 2019. Cross-sectional, cohort, or longitudinal studies that reported on the prevalence of PA, SB, or sleep-related outcomes among immigrant children were included. RESULTS Of 2724 retrieved articles, 55 were selected for full-text screening and 12 met the eligibility criteria. Five studies were based on nationally representative samples. Over half (n = 7; 58%) of the studies assessed only PA, one reported only sleep, three reported both PA and SB, and one reported all three behaviours. Only one study used device-based measure. Assessment of PA and SB varied greatly across the studies with their differing definitions. The prevalence of doing PA ranged from 48 to 72%. Three studies reported an average sedentary time ranging from 1 to 3 h/day. One study reported that 10-13% of immigrant children in the USA had inadequate sleep. All of the studies reviewed were from Western countries with no study from non-Western countries. CONCLUSIONS Future studies should include all three movement behaviours and use standard assessment tools and definitions. Future research should extend beyond Western countries to non-Western countries with immigrant children.

CHILDREN-BASEL 2020; 7:children7050044. [PMID: 32397657 PMCID: PMC7278682 DOI: 10.3390/children7050044] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Revised: 04/02/2020] [Accepted: 05/06/2020] [Indexed: 12/15/2022]
Abstract
Background: Recent research has documented marginalization-related diminished returns (MDRs) of socioeconomic status (SES), defined as weaker effects of SES indicators, such as parental educational attainment, on securing tangible outcomes for the members of socially marginalized (e.g., racial and ethnic minority) groups, compared to privileged social groups (e.g., non-Hispanic Whites). Aims: To explore race/ethnic differences between non-Hispanic Blacks vs. non-Hispanic Whites who attend urban public schools on the effect of parental education on lower school environmental risk among American high schoolers. Methods: For this cross-sectional study, we borrowed the Education Longitudinal Study (ELS-2002) baseline data, a nationally representative study that enrolled 1706 10th grade youths who were attending urban public schools. From this number, 805 (47.2%) were non-Hispanic Black and 901 (52.8%) were non-Hispanic White youths. The dependent variable was the level of school social environmental risk measured using 18 items as self-reported, and was treated as a continuous variable. The independent variable was parental educational attainment, treated as a continuous measure. Gender, region, and parental marital status were the covariates. Race/ethnicity was the moderating variable. Linear regressions were applied to perform our data analysis. Results: Black students were found to attend schools with higher levels of social environmental risk. Youths with parents with a higher educational attainment were found to attend schools with a lower social environmental risk. We found a significant interaction between race (non-Hispanic Black vs. non-Hispanic White) and parental educational attainment on the level of school social environmental risk, suggesting that the protective effect of high parental education on reducing the school social environmental risk was smaller for non-Hispanic Black than for non-Hispanic White youths. Conclusions: Although high parental educational attainment is protective against social environmental risk for American youths, this protective effect is weaker for non-Hispanic Black than non-Hispanic White youths. The diminished returns of parental education in reducing school social environmental risk may explain why the effects of parental education on educational outcomes are smaller for non-Hispanic Black than non-Hispanic White youths (i.e., MDRs). The social environment indirectly generates racial youth educational disparities through deteriorating non-Hispanic Black youth educational outcomes across all SES levels. To prevent the confounding effects of private, suburban, rural, and Catholic schools, we limited this analysis to public urban schools. More research is needed on other settings.

Abstract
BACKGROUND Youth educational outcomes are a function of a wide range of factors including parental education level. This effect, however, is shown to be smaller for African American, Hispanic, and Asian American youth, a pattern called Marginalization-related Diminished Returns (MDRs). It is, however, unknown if it is race/ethnicity or other conditions associated with race/ethnicity (e.g., poor neighborhood quality) which reduces the marginal returns of parental education for youth. AIM To explore whether MDRs are only due to race/ethnicity or if they also remain for non-Hispanic Whites in poor neighborhoods, we compared the association between parental education level and adolescents' school performance based on neighborhood quality in a nationally representative sample of non-Hispanic Whites in the United States. METHODS This cross-sectional study used wave 1 of the Add Health study, an ongoing nationally representative cohort, 1994-2019. Participants included 849 non-Hispanic White adolescents between the ages of 12 and 21 years and their parents. The independent variable was parental education level, which was treated as a continuous measure. Age, grade, gender, and parental marital status were the covariates. The dependent variable was school performance (sum of school grades in Math, English, History, and Science). Linear regression models were used for data analysis. RESULTS Overall, worse neighborhood quality was associated with worse school performance. Parental education level, however, was not directly associated with youth school performance. We found a statistically significant interaction between parental education level and neighborhood quality suggesting that the strength of the association between parental education and youth school performance weakens as neighborhood quality declines. CONCLUSION Parental education level is a more salient determinant of youth educational outcomes in better neighborhoods. The result suggests that MDRs may not be solely due to race/ethnicity but contextual factors that commonly covary with marginalization and poverty. These contextual factors may include segregation, concentration of poverty, and social and physical neighborhood disorder.

Differences in Diet Quality and Snack Intakes Among Non-Hispanic White and Mexican American Adolescents from Different Acculturation Groups. J Racial Ethn Health Disparities 2020; 7:1090-1099.

Abstract
Mexican American adolescents have an increased risk for obesity compared to non-Hispanic whites (NHWs), especially as their degree of acculturation increases. Snack intakes can impact diet quality and may affect obesity risk, yet little is known about differences in snack intakes among NHW and Mexican American adolescents from different acculturation groups. This study compared diet quality and snack intakes among NHW and Mexican American adolescents from different acculturation groups. This study used cross-sectional data from 3636 Mexican American and NHW adolescents in the 2005-2014 National Health and Nutrition Examination Survey. Acculturation was defined based on generational status and language use. Outcomes were Healthy Eating Index-2015 (HEI-2015) score, daily energy intake from snacks, snack frequency, energy value of snacks, and percent contribution of snacks to total daily energy. Analysis of covariance was used to compare outcomes across groups, after adjustment for sex and income. In the full sample, mean HEI-2015 score was 45 ± 0.4. Non-Hispanic white adolescents had modestly poorer diet quality compared to US-born adolescents with a foreign-born parent and Mexican-born adolescents (P < 0.001). Mean daily snack intake was 583 ± 16 kcal. Items in the Snacks and Sweets and Beverages categories contributed more than half of the energy provided by snacks. Non-Hispanic white adolescents had a greater total snack intake compared to all language use at home groups, except equal Spanish and English use. Improving the types of foods consumed as snacks has the potential to partially mitigate differences in snack intakes and diet quality among non-Hispanic white and Mexican American adolescents.

Abstract
Recent research has documented Minorities' Diminished Returns (MDRs), defined as weaker protective effects of parental educational attainment and other socioeconomic status (SES) indicators for racial and ethnic minority groups. To explore racial differences in the associations between parental educational attainment and youth educational outcomes among American high schoolers. This cross-sectional study used baseline data from the Education Longitudinal Study (ELS-2002), a nationally representative survey of 10th grade American youth. This study analyzed 10702 youth who were composed of 2020 (18.9%) non-Hispanic Black and 8682 (81.1%) non-Hispanic White youth. The dependent variables were youth math and reading grades. The independent variable was parental educational attainment. Gender, parental marital status, and school characteristics (% students receiving free lunch, academic risk factors, urban school, public school) were the covariates. Race was the moderating variable. Linear regression was used for data analysis. Overall, higher parental educational attainment was associated with higher math and reading test scores. We found a significant interaction between race (Non-Hispanic Black) and parental education attainment on math and reading test scores, suggesting that the boosting effects of high parental educational attainment on youth educational outcomes might be systemically smaller for Non-Hispanic Black than for Non-Hispanic White youth. While high parental educational attainment promotes educational outcomes for youth, this association is weaker for Non-Hispanic Black youth than non-Hispanic White youth. The diminished returns of parental education are beyond what can be explained by school characteristics that differ between Non-Hispanic Black and non-Hispanic White students. Diminishing returns of parental educational attainment (MDRs) may be an unrecognized source of racial youth disparities. Equalizing SES would not be enough for equalizing outcomes. There is a need for public and economic policies that reduce diminished returns of SES for Black families.

Abstract
The Marginalization-related Diminished Returns (MDR) phenomenon refers to the weaker effects of parental educational attainment for marginalized groups, particularly ethnic minorities. This literature, however, is limited to Blacks and Hispanics; thus, it is not clear if the MDR phenomenon also applies to the educational performance of Asian Americans or not. To explore ethnic differences in the association between parental educational attainment and youth mathematical performance among 10th-grade American high schoolers, this cross-sectional study used baseline data from the Education Longitudinal Study, a national survey of 10th-grade American youth. The analytical sample included a total number of 10,142 youth composed of 1460 (14.4%) Asian-American and 8682 (85.6%) non-Hispanic youth. The dependent variable was youth math performance (standard test score). The independent variable was parental education. Gender, both parents living in the same household, and school characteristics (% students receiving free lunch, urban school, and public school) were the covariates. Ethnicity was the moderating variable. Linear regression was used for data analysis. Overall, parental educational attainment was positively associated with math ability (test score). We observed a statistically significant interaction between ethnicity (Asian American) and parental education attainment on the results of math test scores, indicating that the boosting effect of high parental educational attainment on youth math function is smaller for Asian-American youth than for Non-Hispanic White youth. While high parental educational attainment contributes to youth educational outcomes, this association is weaker for Asian-American youth than non-Hispanic White youth. Diminished returns (weaker effects of parental education in generating outcomes for ethnic minorities) that are previously shown for Hispanics and Blacks also apply to Asian Americans.

Abstract
Background/Objectives: Previous attempts to create national BMI curves for Iranian children and adolescents were limited to local databases. The objective of this study was to build national BMI growth charts for children and adolescents and to report the key percentiles and national cutoff points based on the data obtained from all provinces of Iran. We also aimed to compare our BMI curves to WHO and CDC curves. Methods: In each province, about 1000 children and adolescents (6-18 years) were randomly selected from the urban and rural areas by the multistage stratified cluster sampling method. Across the entire country, 240 trained researchers visited the participants' homes. After obtaining consent forms, these researchers gathered the demographic data, accurate anthropometrics, and BMI measurements. In the data screening and data cleaning levels, the outliers were removed. Then the data sets were smoothed using the log-transformation method. After this, they were converted to Z-scores based on normal distribution and then transformed back to the original scale. Finally, these data sets were used to determine each percentile. Results: A total of 22,718 final cleaned data were analyzed, including 10,921 (48.1%) boys and 11,797 (51.9%) girls. The normal BMI curves of Iranian children and adolescents and comparison to the WHO and CDC curves are presented here. This study introduces the new cutoff points for categorizing Iranian children and adolescents as underweight, normal, overweight, or obese, based on a large-scale national survey. Conclusions: The fifth BMI percentiles in Iranian boys and girls were significantly lower compared to WHO and CDC fifth percentile. Also, the 95th percentile curve in our study was significantly lower than the CDC 95th percentile curves in boys and girls.

Abstract
Background: Failure to recognize children's overweight status by parents may contribute to children's risk for obesity. We examined two methods of measuring mothers' perceptions of children's weight and factors associated with weight perception inaccuracy. Methods: Cross-sectional analyses of clinical and self-report data from 287 Mexican-heritage mother-child dyads. Mothers identified their child's weight category using a scale (e.g., "normal/overweight/obese") and a visual silhouette scale (11 child gender-specific weight-varying images). Children's height and weight were measured to calculate body mass index (BMI). Chi-square tests examined associations between categorical, silhouette, and BMI percentile categories of children's weight. Bivariate logistic regression analyses examined factors associated with mothers' inaccuracy of their children's weight. Results: Only 13% of mothers accurately classified their child as obese using the categorical scale, while 78% accurately classified their child as obese using the silhouette scale. Mothers were more likely to underestimate their child's weight using BMI categories (62%) compared to using the silhouette scale (23%). Predictors of mothers' underestimation using the categorical method were child sex [female] (adjusted odds ratio [AOR] = 1.99; 95% CI: 1.02-3.86), child age [younger age] (AOR = 10.39; 95% CI: 4.16-25.92 for ages 5-6 years), and mother's weight status (overweight AOR = 2.99; 95% CI: 1.05-8.51; obese AOR = 5.19; 95% CI: 1.89-14.18). Child BMI was the only predictor of mothers' overestimation (AOR = 0.89; 95% CI: 0.85-0.94) using the silhouette method. Conclusions: Using silhouette scales to identify children's body weight may be a more accurate tool for clinicians and interventionists to activate parents' awareness of unhealthy weight in children compared to using traditional categorical weight-labeling methods.

Abstract
Objectives: Marginalization-related diminished returns (MDRs) refer to weaker health effects of educational attainment for socially marginalized groups compared to the socially privileged groups. Most of the existing literature on MDRs, however, has focused on marginalization due to race, ethnicity, and sexual orientation. Thus, very limited information exists on MDRs of educational attainment among immigrant populations in the United States. Aims: Building on the MDRs framework and using a nationally representative sample of US adults, we compared immigrant and native-born adults for the effects of educational attainment on psychological distress, self-rated health (SRH), and chronic diseases (CDs). Methods: The 2015 National Health Interview Survey (NHIS) has enrolled 33,672 individuals who were either immigrant (n = 6,225; 18.5%) or native born (n = 27,429; 81.5%). The independent variable (IV) was educational attainment, which was treated as a categorical variable. The dependent variables included psychological distress, SRH, and CDs, all of which were dichotomous variables. Age, gender, race, ethnicity, and region were confounders. Immigration (nativity status) was the moderator. Results: Higher educational attainment was associated with lower odds of psychological distress, poor SRH, and CDs. However, immigration showed a significant statistical interaction with college graduation on all outcomes, which were suggestive of smaller protective effects of college graduation on psychological distress, poor SRH, and CDs for immigrant than native-born adults. Conclusions: In the US, the associations between educational attainment and psychological distress, SRH, and CDs are all weaker for immigrant than native-born adults. To prevent health disparities, it is essential to decompose health inequalities that are due to low educational attainment from those that are due to diminished returns of educational attainment (i.e., MDRs). There is a need to help highly educated immigrant adults secure positive health outcomes, similar to their native-born counterparts. Such changes may require bold and innovative economic, public, and social policies that help immigrant adults to more effectively mobilize their educational attainment to secure tangible outcomes. Elimination of health disparities in the US requires efforts that go beyond equalizing access to education.

Assari S, Caldwell CH, Bazargan M. Association Between Parental Educational Attainment and Youth Outcomes and Role of Race/Ethnicity. JAMA Netw Open 2019; 2:e1916018. [PMID: 31755951 PMCID: PMC6902825 DOI: 10.1001/jamanetworkopen.2019.16018] [Citation(s) in RCA: 67] [Impact Index Per Article: 13.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 09/23/2019] [Indexed: 02/06/2023] Open
Abstract
Importance The concept of minorities' diminished returns refers to the smaller protective effects of educational attainment for racial and ethnic minority groups compared with those for majority groups. Objective To explore racial and ethnic differences in the associations between parental educational attainment and youth outcomes among US adolescents. Design, Setting, and Participants A cross-sectional study was performed of 10 619 youth aged 12 to 17 years who were participants at wave 1 of the Population Assessment of Tobacco and Health (PATH) study, a nationally representative survey, in 2013. Data analysis was performed from August to October 2019. Main Outcomes and Measures The dependent variables were youth tobacco dependence, aggression, school performance, psychological distress, and chronic medical conditions. The independent variable was parental educational attainment. Age and sex of the adolescents and marital status of the parents were the covariates. Race and ethnicity were the moderating variables. Logistic regression was used for data analysis. Results Among the participants, 5412 (51.0%) were aged 12 to 15 years, and 5207 (49.0%) were aged 16 to 17 years; 5480 (51.7%) were male. For non-Hispanic white youth, as parental educational attainment increased, there were stepwise reductions in the prevalence of tobacco dependence (13.2% vs 6.9% vs 2.7%), aggression (37.9% vs 34.8% vs 26.1%), low grade point average (84.2% vs 75.6% vs 53.3%), and chronic medical conditions (51.7% vs 50.8% vs 43.9%), but there was not such a trend for psychological distress (43.7% vs 48.6% vs 41.0%). Interactions were significant between Hispanic ethnicity and parental education on tobacco dependence (OR, 3.37 [95% CI, 2.00-5.69] for high school graduation; OR, 5.40 [95% CI, 2.52-11.56] for college graduation; P < .001 for both), aggression (OR, 1.41 [95% CI, 1.09-1.81]; P = .008 for high school graduation; OR, 1.59 [95% CI, 1.14-2.21]; P = .006 for college graduation), and psychological distress (OR, 1.50 [95% CI, 1.05-2.13]; P = .03). Black race showed an interaction with college graduation on poor school performance (OR, 2.00 [95% CI, 1.26-3.17]; P = .003) and chronic medical conditions (OR, 1.56 [95% CI, 1.14-2.14]; P = .005). All these findings suggest that the protective associations between high parental educational attainment and youth development might be systemically smaller for Hispanic and black youth than for non-Hispanic youth. Conclusions and Relevance Although high parental educational attainment is associated with better outcomes for youth, this association is systemically less significant for Hispanic and black than non-Hispanic white youth. The result is an increased health risk in youth from middle class black and Hispanic families. Given the systemic pattern for outcomes across domains, the diminishing returns of parental educational attainment may be due to upstream social processes that hinder ethnic minority families from translating their capital and human resources into health outcomes.

Abstract
Objectives We examined the association between prepregnancy body mass index (PP-BMI) and preterm birth (PTB) among women in Puerto Rico (PR) as a potentially modifiable risk factor. Methods We conducted a retrospective study using the birth certificate data files from 2005 to 2012 developed by the PR Department of Health to examine the relationship between PP-BMI and PTB. Logistic regression was used to determine crude and adjusted odds ratios (OR) and 95% confidence intervals (CI) for the categories of PP-BMI of overweight (25-29.9 kg/m2), obesity (≥ 30 kg/m2), and overweight and obesity together (≥ 25 kg/m2) and PTB. Stratified analysis explored the associations between PP-BMI and PTB by region within PR and year. Results Following exclusions of birth records with missing data, 343,508 births were included in our analysis. The percentage of PTB decreased from 18.6 to 15.2 during our study period. Statistically significant differences were observed between preterm and full term births across all covariates. Overweight (OR 1.08, 95% CI 1.06, 1.11), obesity (OR 1.17, 95% CI 1.14, 1.20), and overweight and obesity together (OR 1.11, 95% CI 1.09, 1.14) were significantly associated with increased odds of PTB after adjusting for confounders. The associations between PP-BMI and PTB persisted across all regions and years. Conclusions for Practice PP-BMI is associated with increased odds of PTB among women in PR and the associations were consistent in exploratory analyses. Future research should examine the relationship between PP-BMI and PTB among other Hispanic subgroups and among Puerto Ricans in the mainland United States.

Abstract
BACKGROUND Parental educational attainment is shown to be protective against health problems; the Minorities' Diminished Returns theory, however, posits that these protective effects tend to be smaller for socially marginalized groups particularly blacks than whites. AIMS To explore racial differences in the effect of parental educational attainment on body mass index (BMI) in a national sample of US adolescents. METHODS In this cross-sectional study, we used baseline data of 10,701 (8678 white and 2023 black) 12-17 years old adolescents in the Population Assessment of Tobacco and Health (PATH; 2013). Parental educational attainment was the predictor. Youth BMI (based on self-reported weight and height) was the dependent variable. Age, gender, ethnicity, and family structure were covariates. Race was the focal moderator. RESULTS Overall, higher parental educational attainment was associated with lower youth BMI. Race, however, moderated the effect of parental educational attainment on BMI, suggesting that the protective effect of parental educational attainment on BMI is significantly smaller for black than white youth. CONCLUSIONS In the United States, race alters the health gains that are expected to follow parental educational attainment. While white youth who are from highly educated families are fit, black youth have high BMI at all levels of parental educational attainment. This means, while the most socially privileged group, whites, gain the most health from their parental education, blacks, the least privileged group, gain the least. Economic, social, public, and health policymakers should be aware that health disparities are not all due to lower socioeconomic status (SES) of the disadvantaged group but also diminished returns of SES resources for them. Black-white health disparities exist across all high socioeconomic status (SES) levels.

Abstract
Background: Parental educational attainment is protective against chronic medical conditions (CMCs). According to the minorities’ diminished returns (MDRs) theory, however, the health effects of socioeconomic status (SES) indicators are smaller for socially marginalized groups such as racial and ethnic minorities rather than Whites. Aims: To explore racial and ethnic differences in the effect of parental educational attainment on CMCs in a nationally representative sample of American youth. Methods: In this cross-sectional study, we used baseline data of 10,701 12–17 years old youth in the Population Assessment of Tobacco and Health (PATH; 2013). Parental educational attainment was the independent variable. The dependent variable was the number of CMCs in youth. Age, gender, and family structure were covariates. Race and ethnicity were the focal moderators. Linear and multinomial regression were applied to analyze the data. Results: Overall, higher parental educational attainment was associated with a lower number of CMCs. Race and ethnicity, however, showed significant interactions with parental educational attainment on a number of CMCs as well as 2+ CMCs, suggesting that the effect of parenting educational attainment on CMCs is significantly smaller for Black and Hispanic than White youth. Conclusions: In the United States, race and ethnicity alter the health gains that are expected to follow parental educational attainment. While White youth who are from highly educated families are most healthy, Black and Hispanic youth from highly educated families remain at higher risk for CMCs. That means, while the most socially privileged group, Whites, gain the most health from their parental education, Blacks and Hispanics, the least privileged groups, gain the least. The result is a disproportionately high number of CMCs in middle-class Blacks and Hispanics. Economic, social, public, and health policy makers should be aware that health disparities are not all due to lower SES of the disadvantaged group but also diminished returns of SES resources for them. Youth physical health disparities due to race and ethnicity exist across all SES levels.

Abstract
BACKGROUND Hispanics are the largest minority population in the United States (18%). They represent a heterogeneous and growing population. Cancer is the leading cause of death among Hispanics, yet few studies have described cancer mortality burden by specific Hispanic group nationwide. METHODS Cancer-related deaths from U.S. death certificates for the years 2003-2012 were analyzed for decedents identifying as Mexican, Puerto Rican, Cuban, and Central or South American. We calculated descriptive statistics, including potential years of lives lost (PYLL), age-adjusted rates, standardized mortality ratios, and fitted JoinPoint regression models, to evaluate annual trends by Hispanic group, using non-Hispanic Whites (NHW) as the reference population. RESULTS We identified 287,218 cancer-related deaths among Hispanics and 4,570,559 among NHWs. Mortality trends were heterogeneous across Hispanic groups. Female NHWs and male Puerto Ricans had the greatest rates of adjusted PYLL per 1,000 (NHWs, 19.6; Puerto Ricans, 16.5). Liver cancer was ranked among the top 5 cancer-related deaths for every Hispanic group, but not for NHWs. Stomach cancer mortality was twice as high for most Hispanic groups when compared with NHWs and especially high for Mexicans [male standardized mortality ratio (SMR), 2.07; 95% confidence interval (CI), 2.01-2.13; female SMR, 2.62; 95% CI, 2.53-2.71]. CONCLUSIONS We observed marked heterogeneity in cancer mortality across Hispanic groups. Several cancers affect Hispanics disproportionately compared with NHWs. Screening programs in Hispanics should be considered for stomach and liver cancer. IMPACT Disaggregated analysis of Hispanics is needed to fully understand cancer burden among the diverse Hispanic population and is critical for cancer prevention and control efforts.

Abstract
OBJECTIVES Few studies have focused on weight change and frailty, especially in Asia. This research aimed to evaluate midlife body mass index (BMI) trajectory and assess its relationship with frailty 8 years later in Taiwan. DESIGN A prospective cohort study. SETTING AND PARTICIPANTS Data were retrieved from the Taiwan Longitudinal Study on Aging conducted from 1999 to 2007. The analysis was restricted to respondents aged between 50 to 69 years old, who were not frail in 1999 and were alive in 2007 (n=1609). MEASUREMENTS Frailty was defined using the Fried criteria. The group-based model of trajectory was used to estimate BMI trajectories among elderly participants. Logistic regression analysis was used to examine the association between BMI change and frailty. RESULTS Four trajectory classes were identified and each remained stable during the 8-year follow-up. There were 316 participants (20.3%) in the low-normal weight group (baseline BMI=20.38 kg/m2), 737 participants (44.7%) in the high-normal weight group (baseline BMI=23.22 kg/m2), 449 participants (28.4%) in the overweight group (baseline BMI=26.24 kg/m2), and 107 participants (6.6%) in the obesity group (baseline BMI=30.65 kg/m2). After adjustment for confounding factors, the low-normal weight group and obesity group were associated with increased frailty compared with the high-normal weight group. CONCLUSION Our results showed that the BMI trajectories of midlife individuals tended to be constant and those in both the low-normal weight group and obesity group had an increased risk of developing frailty in later life. Therefore, an optimal weight-targeting strategy should be considered for Asian elderly individuals.

Abstract
BACKGROUND AND AIMS In this analysis, we estimated population-level trajectory groups of life course cardiovascular risk to explore their impact on mid-life atherosclerotic and metabolic outcomes. METHODS This prospective study followed n = 1269 Bogalusa Heart participants, each with at least 4 study visits from childhood in 1973 through adulthood in 2016. We used discrete mixture modeling to determine trajectories of cardiovascular risk percentiles from childhood to adulthood. Outcomes included mid-life subclinical atherosclerotic measures [(carotid intima-media thickness (cIMT), pulse wave velocity (PWV)], metabolic indicators [(diabetes and body mass index (BMI)], and short physical performance battery (SPPB). RESULTS Between the mean ages of 9.6-48.3 years, we estimated five distinct trajectory groups of life course cardiovascular risk (High-Low, High-High, Mid-Low, Low-Low, and Low-High). Adult metabolic and vascular outcomes were significantly determined by life course cardiovascular risk trajectory groups (all p < 0.01). Those in the High-Low group had lower risks of diabetes (20% vs. 28%, respectively; p = .12) and lower BMIs (32.4 kg/m2vs. 34.6 kg/m2; p = .06) than those who remained at high risk (High-High) throughout life. However, the High-Low group had better cIMT (0.89 mm vs. 1.05 mm; p < .0001) and PWV (7.8 m/s vs. 8.2 m/s; p = .03) than the High-High group. For all outcomes, those in the Low-Low group fared best. CONCLUSIONS We found considerable movement between low- and high-relative cardiovascular risk strata over the life course. Children who improved their relative cardiovascular risk over the life course achieved better mid-life atherosclerotic health despite maintaining relatively poor metabolic health through adulthood.

Abstract
Introduction: National data on the epidemiology of cancer are commonly reported by broad racial/ethnic categories, such as "Hispanic." However, few studies have disaggregated Hispanic groups and explored mortality differentials in this heterogeneous population. This paper aims to further examine cancer mortality differentials among Hispanic subgroups in the U.S. Materials and Methods: The study examined cancer deaths in the United States from 2004 to 2014 among decedents classified as Mexican, Puerto Rican, Cuban, Dominican, Central/South American and non-Hispanic white on the death certificate among those who were 20 years or older at the time of death. Data were obtained from the National Vital Statistics System. Sex-specific age-adjusted mortality rates were computed for a 10-year period and each individual year, for all cancers combined. Differences by age group, cancer sites, and age distribution were also assessed. Results: A total of 296,486 Hispanic cancer deaths were identified. Mortality rates of the Hispanic subgroups compare favorably with those of non-Hispanic whites. The mortality rates for Mexicans are very similar to those of all Hispanics combined, whereas the rates for Cuban and Puerto Ricans are higher. Dominicans and Central/South Americans had the overall lowest mortality rates. Statistically significant decreases in cancer mortality rates were noted in some sub-groups, but rates increased among Dominican women. Age-adjusted mortality rates by cancer site varied among Hispanics subgroups and gender. Among Cubans, only 5% of cancer deaths occurred before the age of 50 compared to 16% of cancer deaths among Central/South American. Conclusion: While it is common to present data on the burden of cancer among Hispanics as an aggregate group, this study illustrates that the burden of cancer varies by Hispanic subgroups. The disaggregation of Hispanics by ancestry/country of origin allows for a clearer understanding of the health status of this growing population and is needed if health disparities are to be adequately identified, understood and addressed.

Abstract
OBJECTIVE To examine whether the relationship between nativity and overweight/obesity has changed over time among Mexican American children and to investigate the implications of this pattern on overweight/obesity disparities relative to non-Hispanic white children. METHODS Using cross-sectional data from Mexican American and non-Hispanic white children aged 4 to 17 years participating in the National Health and Nutrition Examination Surveys (1988-1994 [N = 4,720] and 2005-2014 [N = 7,275]) log-binomial regression was used to calculate prevalence ratios (PRs) of overweight/obesity by nativity status adjusting for sociodemographic covariates, survey period, and a nativity-by-survey period interaction. A separate covariate-adjusted model tested a three-level interaction between ethnicity, nativity, and survey period that included non-Hispanic white children. RESULTS In 1988-1994, foreign-born Mexican Americans had significantly lower prevalence of overweight/obesity compared with US-born Mexican Americans (PR = 0.75, 95% CI: 0.61-0.94). However, by 2005-2014, the nativity gap in overweight/obesity had closed (PR = 0.94, 95% CI: 0.84-1.07). Moreover, while foreign-born Mexican Americans had the lowest levels of overweight/obesity in 1988-1994, by 2005-2014, foreign-born and US-born Mexican Americans had comparable estimates, both significantly higher than that of non-Hispanic white individuals. CONCLUSIONS Although overweight/obesity disparities between Mexican Americans and non-Hispanic white Americans had previously been specific to US-born Mexican Americans, disparities in more recent years have extended to foreign-born Mexican Americans.

[PMID: 29769702 DOI: 10.1038/s41366-018-0056-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 12/29/2017] [Accepted: 01/31/2018] [Indexed: 11/09/2022]
Abstract
BACKGROUND/OBJECTIVES Mexico has one of the highest prevalence of childhood obesity in the world. Genome-wide association studies (GWAS) for obesity have identified multiple single-nucleotide polymorphisms (SNPs) in populations of European, East Asian, and African descent. The contribution of these loci to obesity in Mexican children is unclear. We assessed the transferability of 98 obesity loci in Mexican children and fine-mapped the association signals. SUBJECTS/METHODS The study included 405 and 390 Mexican children with normal weight and obesity. Participants were genotyped with a genome-wide dense SNP array designed for Latino populations, allowing for the analysis of GWAS index SNPs as well as fine-mapping SNPs, totaling 750 SNPs covering 98 loci. Two genetic risk scores (GRS) were constructed: a "discovery GRS" and a "best-associated GRS", representing the number of effect alleles at the GWAS index SNPs and at the best-associated SNPs after fine-mapping for each subject. RESULTS Seventeen obesity loci were significantly associated with obesity, and five had fine-mapping SNPs significantly better associated with obesity than their corresponding GWAS index SNPs in Mexican children. Six obesity-associated SNPs significantly departed from additive to dominant (N = 5) or recessive (N = 1) models, and a significant interaction was found between rs274609 (TNNI3K) and rs1010553 (ITIH4) on childhood obesity risk. The best-associated GRS was significantly more associated with childhood obesity (OR = 1.21 per additional risk allele [95%CI:1.17-1.25], P = 4.8 × 10-25) than the discovery GRS (OR = 1.05 per additional risk allele [95%CI:1.02-1.08], P = 8.0 × 10-4), and was also associated with waist-to-hip ratio, fasting glucose, fasting insulin and triglyceride levels, the association being mediated by obesity. An overall depletion of obesity risk alleles was observed in Mexican children with normal weight when compared to GWAS discovery populations. CONCLUSIONS Our study indicates a partial transferability of GWAS obesity loci in Mexican children, and supports the pertinence of post-GWAS fine-mapping experiments in the admixed Mexican population.

Abstract
OBJECTIVES U.S.-born Hispanic infants have a well-documented health advantage relative to other minority groups. However, little published research has examined racial heterogeneity within the Hispanic population, in relation to health outcomes. The current study aims to explore possible implications of racial identification for the health of U.S. born Hispanic compared to non-Hispanic infants. Methods Data were drawn from 2007 to 2008 NCHS Cohort Linked Live Birth-Infant Death Files, restricted to deliveries of Hispanic black, Hispanic white, non-Hispanic black (NHB) and non-Hispanic white mothers (NHW) (n = 7,901,858). Adjusted odds ratios for first week mortality, neonatal, postneonatal, and overall infant mortality were calculated for each group, using NHW as the reference group. RESULTS A distinct health gradient was observed in which NHB infants (n = 1,250,222) had the highest risk of first week (aOR 2.29, CI 2.21-2.37), neonatal (aOR 2.23, CI 2.17-2.30), postneonatal (aOR 1.74, CI 1.68-1.81), and infant mortality (aOR 2.05, CI 2.00-2.10) compared to NHW infants (n = 4,578,150). Hispanic black infants (n = 84,377) also experienced higher risk of first-week (aOR 1.28 (1.12-1.47), neonatal (aOR .27, CI 1.13-1.44), postneonatal (aOR 1.34, CI 1.15-1.56), and infant mortality (aOR 1.30, CI 1.18-1.43) compared to both NHW and Hispanic white infants (n = 1,989,109). Conclusions for Practice: Risk of infant mortality varies among Hispanic infants by race, with poorer outcomes experienced by Hispanic black infants. Compared to non-Hispanic infants of the same race, Hispanic black infants experience a smaller health disadvantage and Hispanic white infants have better or similar infant health outcomes. Our findings suggest implications of racial heterogeneity on infant health outcomes, and provide insight into the role of race as a social construct.

Abstract
BACKGROUND/OBJECTIVES An increase in mean body mass index (BMI) or prevalence of obesity may be accompanied by changes in the population BMI distribution. This study aimed to examine how the distributions of BMI and waist circumference (WC) have changed in South Korea over a 16-year interval (1998-2014). SUBJECTS/METHODS Using the Korea National Health and Nutrition Examination Survey, we analyzed changes in mean, standard deviation (SD), 5th, and 95th percentile values of BMI and WC distributions for 46,343 (BMI) and 46,327 (WC) adults aged 25-64 years. RESULTS For men, mean BMI increased at an annual rate of 0.060 units (95% CI: 0.047-0.073) with annual increases of 0.029 units in SD (95% CI: 0.019-0.039), 0.121 units in the 95th percentile (95% CI: 0.097-0.145) and 0.042 units in the 5th percentile (95% CI: 0.021-0.062). The 95th percentile and SD of the WC distribution increased, but not mean WC and the 5th percentile. For women, mean BMI decreased at an annual rate of 0.030 units (95% CI: 0.010-0.049) with a 0.030-unit increase in SD (95% CI: 0.012-0.048) and a 0.049-unit decrease in the 5th percentile (95% CI: 0.029-0.070). Mean WC also decreased with an increase in SD and a decrease in the 5th percentile. CONCLUSIONS These findings suggest increasing dispersion in the distribution of BMI and WC derived from significant shifts in the upper tails for Korean men, but not women. Future research needs to identify the factors that underlie the increasing dispersion of obesity measures.

Abstract
There have been conflicting findings regarding the relationship between body mass index (BMI) and self-rated health (SRH) worldwide. The purpose of this study was to examine the association between BMI and SRH by comparing its relationship in four East Asian countries: South Korea, China, Japan, and Taiwan. Using data from the East Asian Social Survey, the relationship between weight status and SRH status was investigated and compared between four countries, China, Japan, South Korea, and Taiwan. An ordinal logit regression model was estimated for each country, and the results were compared. We found that the relationship between weight status and SRH status differed across the four countries. In China, people who were overweight reported better SRH scores than those of normal weight, whereas in Japan, obese and severely obese people reported poor scores. In contrast, South Koreans who were underweight, obese, or severely obese reported poor ratings of health status than those of normal weight. In Taiwan, however, no differences in respondents' weight status were found across SRH scores. There were notable differences in the relationship between BMI and SRH status in four East Asian countries. Individual countries should consider these relationships when designing and implementing obesity intervention programs.

Abstract
BACKGROUND Central obesity is a major risk factor for cardiometabolic diseases. The prevalence of central obesity has not been reported fully among Asian adults in the United States (US). METHODS Cross-sectional data of 1288 Asian adults aged 20 years or over was selected from the US National Health and Nutrition Examination Survey with a stratified multi-stage sampling design. The prevalence of central obesity was calculated with 95% confidence intervals (CIs) and Chi-square tests were conducted to test the significance of the prevalence differences across characteristic groups. RESULTS The overall prevalence of central obesity among US Asian adults was 58.1% in 2011-2014. The prevalence of central obesity was higher in older adults (73.5%) than in young adults (45.4%) (p < 0.0001). Women had 13.4% higher prevalence than men (64.4% vs 51.0%, p < 0.0001). The prevalence increased over time (2011-2012 vs 2013-2014) in young adults (39.2% vs 51.5%), men (45.4% vs 56.6%), adults with college education or above (54.2% vs 61.7%) and non-poor adults (55.4% vs 62.4%). Compared with men, women had higher prevalence in each subgroup of age, education, poverty, and length of time (except for the subgroup of "born in the US") (all p < 0.05) and in the subgroup of "married or living with partner" for marital status (p < 0.0001). CONCLUSION Central obesity is prevalent in Asian adults, particularly in older adults and women. More efforts are needed to prevent and treat obesity in Asian adults as Asians are incurring the greatest increase in type 2 diabetes in parallel with the rising rate of central adiposity.

Abstract
INTRODUCTION Heavy episodic alcohol use during young adulthood may contribute to excess weight gain and transition from healthy weight to overweight/obesity. This study is the first to evaluate the association between heavy episodic drinking during early adulthood and transition to overweight/obese status 5 years later using data from the U.S. National Longitudinal Study of Adolescent to Adult Health. METHODS The study used data from Waves III and IV, when participants were aged 18-26 and 24-32 years, respectively. The final sample consisted of 7,941 participants with measured height/weight who reported ever drinking alcohol. Multinomial logistic regression models tested the association between heavy episodic drinking and risk of transitioning to an unhealthy weight class. RESULTS Heavy episodic drinking was associated with 41% higher risk of transitioning from normal weight to overweight (relative risk ratio, 1.41; 95% CI=1.13, 1.74; p=0.002) and 36% higher risk of transitioning from overweight to obese by Wave IV (relative risk ratio, 1.36; 95% CI=1.09, 1.71; p=0.008), compared with individuals not drinking heavily, while accounting for covariates. Heavy episodic drinking was associated with 35% higher risk of maintaining obesity (relative risk ratio, 1.35; CI=1.06, 1.72; p=0.016) and gaining excess weight (OR=1.20, 95% CI=1.03, 1.39, p=0.02). CONCLUSIONS Regular heavy episodic drinking in young adulthood is associated with higher risk of gaining excess weight and transitioning to overweight/obesity. Obesity prevention efforts should address heavy drinking as it relates to caloric content and risk of transitioning to an unhealthy weight class.

Breastfeeding in Infancy Is Associated with Body Mass Index in Adolescence: A Retrospective Cohort Study Comparing American Indians/Alaska Natives and Non-Hispanic Whites. J Acad Nutr Diet 2017; 117:1049-1056. [PMID: 28082060 PMCID: PMC5586593 DOI: 10.1016/j.jand.2016.11.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2015] [Accepted: 11/17/2016] [Indexed: 01/16/2023]
Abstract
BACKGROUND American Indians and Alaska Natives have the highest obesity prevalence in the United States, but the influence of early childhood variables on body mass index (BMI; calculated as kg/m2) is not well understood. Previous studies have investigated the association between breastfeeding in infancy and offspring BMI, but rarely included American Indians and Alaska Natives. OBJECTIVE This study investigated the association between breastfeeding in infancy and BMI in American Indians and Alaska Native and non-Hispanic white adolescents and young adults. DESIGN Longitudinal analysis based on data from the National Longitudinal Study of Adolescent to Adult Health (1994 to 2008). PARTICIPANTS Adolescent respondents who self-identified as American Indians and Alaska Native or non-Hispanic white, and whose parents completed the parental questionnaire, reported their height and weight. The final sample included 655 American Indians and Alaska Native and 10,305 non-Hispanic white respondents. STATISTICAL ANALYSES PERFORMED Generalized estimating equations were used to measure the mean differences, 95% CIs, and P values of the association between breastfeeding in infancy and offspring BMI in adolescence, stratifying by race, and adjusting for demographic and socioeconomic variables. RESULTS The length of breastfeeding was inversely associated with BMI in both populations. American Indians and Alaska Natives that were breastfed for 6 to 12 months or for more than 12 months had a mean BMI of 2.69 (95% CI -3.46 to -1.92; P<0.01) and 1.54 (95% CI -2.75 to -0.33; P<0.05) units lower than those that were never breastfed. Non-Hispanic whites that were breastfed for 3 to 6 months, 6 to 12 months, or more than 12 months had a mean BMI of 0.71 (95% CI -0.93 to -0.50; P<0.01), 0.68 (95% CI -0.87 to -0.50; P<0.01), and 0.85 (95% CI -1.09 to -0.62; P<0.01) units lower than those that were never breastfed. The association between the length of breastfeeding and offspring BMI varied by race (P<0.01). CONCLUSIONS Breastfeeding in infancy is associated with lower mean BMI. Future research should investigate causal pathways and whether interventions promoting breastfeeding in American Indians and Alaska Natives can prevent increasing BMI.

Abstract
Childhood obesity is increasingly prevalent worldwide, and Portugal presents one of the highest prevalence of obesity and overweight among the European countries. Since childhood obesity is a risk factor for obesity in adulthood, the high prevalence of overweight and obesity in paediatric age currently experienced is expected to lead to even higher prevalence of obesity in adulthood in future decades. It is well known that the prenatal period and infancy are critical or sensitive periods for obesity development, but a growing body of evidence also suggests a relevant role of childhood and adolescence. The exposure to some factors during these periods or specific time frames within these periods may confer additional risk for obesity development. Paediatric obesity is associated with cardiovascular risk factors both in the short or medium-term, but also in the long term, conferring additional risk for future adult health. However, it is not clear whether the relation between paediatric obesity and adult health is independent of adult adiposity. There is a moderate to high tracking of obesity from paediatric age into adulthood, which may partially explain the association with adult outcomes. Therefore, there has been increasing interest on life course frameworks to study the effect of the dynamics of adiposity across paediatric age on adult outcomes, namely on the cardiovascular disease risk. The use of this approach to study determinants and consequences of obesity raises methodological challenges to summarize the exposure to adiposity/obesity across the life span, being the identification of growth trajectories and the quantification of the duration of obesity among the most used methods. However, further investigation is still needed to explore the best methods to summarize exposure to adiposity and its variation across time.

Abstract
Multilevel/hierarchical obesity studies analyze adolescent and family, neighbourhood and social settings' characteristics to generate data needed to design prevention interventions. This scoping study summarizes such studies' characteristics and key findings to provide information to decision makers, which allows them to quickly grasp the state of the evidence and potential policy implications for adolescent obesity prevention. PubMed, CINAHLplus, PsychINFO and Sociological Abstracts were searched for peer-reviewed studies spanning 1 January 2000-31 August 2014. Inclusion criteria included (i) outcome weight status, physical activity and weight status, or physical activity alone if the aim was obesity prevention; (ii) 12- to 19-year-old participants in a cross-sectional study, a separate analysis in a cross-sectional study or a longitudinal follow-up. Nineteen studies were published in the United States of America; four in Canada; two in Spain, China and Vietnam, respectively; and one in Germany. Self-efficacy, parental physical activity support, perceived neighbourhood support, social cohesion and access to recreational facilities were associated with increased activity levels; neighbourhood physical disorder and perceived lack of safety associated with reduced physical activity levels. Overweight or obesity was associated with sugar-sweetened beverage intake and household availability thereof; reduced odds were reported with fruit and vegetable intake and household availability of these, daily breakfast and family meal frequency. Potential adolescent obesity risk regulators may be found at the individual, family or social contextual levels.

Abstract
OBJECTIVE The prevalence of obesity in Mexico has increased at an alarming rate in both adults and children. This study was undertaken to test in Mexican children the effects of single nucleotide polymorphisms (SNP) that have been associated with body mass index (BMI) and obesity in Europeans. METHODS School-age children (N = 1,559, 5-17 years) were recruited in Mexico City. Thirty-five SNPs with established effects on BMI and obesity were genotyped and analyzed individually and as a combined gene score (GS). RESULTS SNPs in FAIM2 (rs7138803), GPRC5BB (rs12444979), MTIF3 (rs4771122), TFAP2B (rs987237), TMEM18 (rs7561317), and the GS were significantly associated with BMI. The GS explained 0.9% of the variance of BMI. Also, SNPs in LRRN6C (rs10968576) and MC4R (rs17782313) were significantly associated with overweight and obesity categories, respectively. Importantly, the effect allele frequency of 26/35 SNPs (74.3%) differed significantly between Mexican children and European adults. No significant gene × environment or gene × gene interactions were detected after Bonferroni adjustment. CONCLUSIONS Several SNPs first associated with BMI/obesity in European adults replicated well in Mexican children, and investigating differences in the distribution of effect alleles across ethnic populations may shed light on genetic susceptibilities of different populations to obesity.

[PMID: 27196145 DOI: 10.1016/j.ypmed.2016.05.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2015] [Revised: 05/06/2016] [Accepted: 05/15/2016] [Indexed: 11/21/2022]
Abstract
BACKGROUND The literature suggests an association between poor school performance and obesity. However, little is known about academic achievement and behavior as possible risk factors for future obesity. METHOD The analysis was based on data from 3172 participants aged 6 to 25years from the US National Longitudinal Survey conducted 1986 to 2010. Academic achievement, behavior problems and body mass index (BMI) were assessed at childhood (6-9) and teenhood (10-14). Height and weight were self-reported at pre-young adulthood (15-18) and young adulthood (19-25). RESULTS Based on logistic regression stratified by sex and race/ethnicity, academic and behavioral deficiencies during childhood and teenhood were risk factors for young adult obesity with some sex and ethnic/racial differences. The highest prevalence rates of obesity by race/ethnicity and sex are as follows: black/Hispanic females, those in the lowest quartile of teen reading and math (32.8%); black/Hispanic males, those in lowest quartile of teen reading (26.1%); white males, those in the highest quartile of behavioral problems (21.9%); and white females, those in the lowest quartile teen math (23.2%). CONCLUSION Poor school performance in childhood and teenhood is associated with an increased risk of adult obesity. Prospective studies should further examine the association of school performance and adult obesity and whether programs directed at improving school performance may have secondary gains in preventing obesity.

Cook WK, Tseng W, Bautista R, John I. Ethnicity, socioeconomic status, and overweight in Asian American adolescents. Prev Med Rep 2016; 4:233-7. [PMID: 27413687 PMCID: PMC4929066 DOI: 10.1016/j.pmedr.2016.06.010] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 04/28/2016] [Accepted: 06/06/2016] [Indexed: 11/18/2022] Open
Abstract
Asian American children and adolescents are an under-investigated subpopulation in obesity research. This study aimed to identify specific profiles of Asian subgroups at high risk of adolescent overweight with special attention to Asian ethnicity, socioeconomic status (SES), and their interaction. Multiple logistic regression models were fitted using a sample of 1533 Asian American adolescents ages 12–17 from the 2007–2012 California Health Interview Survey (CHIS). In addition to Asian ethnicity and socioeconomic status (assessed by family income and parental education level), age, gender, nativity, and two lifestyle variables, fast food consumption and physical activity, were also controlled for in these models. Key predictors of overweight in Asian American adolescents included certain Asian ethnicities (Southeast Asian, Filipino, and mixed ethnicities), low family income (< 300% of the Federal Poverty Level), and being male. Multiplicative interaction terms between low family income and two ethnicities, Southeast Asian and Vietnamese that had the lowest SES among Asian ethnic groups, were significantly associated with greatly elevated odds of being overweight (ORs = 12.90 and 6.67, respectively). These findings suggest that high risk of overweight in Asian American adolescents associated with low family incomes may be further elevated for those in low-income ethnic groups. Future research might investigate ethnic-group SES as a meaningful indicator of community-level socioeconomic disparities that influence the health of Asian Americans. Southeast Asian and Filipino ethnicities were associated with adolescent overweight. Low family income was positively associated with Asian adolescent overweight. Ethnicity and low family income interacted to increase risk of adolescent overweight.

Abstract
INTRODUCTION Facebook is the most popular online platform among adolescents and can be an effective medium to deliver health education. Although Korean American (KA) adolescents are at risk of obesity, a culturally tailored health education program is not available for them. Thus, our research team developed a health education program for KA adolescents on Facebook called "Healthy Teens." The aim of this study was to discuss important lessons learned through the program development process. METHOD This program includes culturally tailored learning modules about healthy eating and physical activity. The program was developed on the basis of the social cognitive theory, and the online program was developed by applying Web usability principles for adolescents. Upon completion, the usability of the program was assessed using heuristic evaluation. RESULTS The findings from the heuristic evaluation showed that the Healthy Teens program was usable for KA adolescents. DISCUSSION The findings from this study will assist researchers who are planning to build similar Facebook-based health education programs.

Abstract
This review focuses on obesity, asthma and mental health functioning as salient health issues affecting Hispanic youth. Burden of these conditions and consequences for adult health are also discussed. Hispanic youth are affected by obesity at an early age; the prevalence of obesity among Hispanic children 6-11 years old is twice as high as the prevalence for non-Hispanic White children of the same age, but among 2-5 years old is 4 times higher. Asthma disproportionally affects certain Hispanic groups, notably children of Puerto Rican ancestry, and the comorbidity of asthma and obesity is an emerging health issue. Another area of concern is the scant data on mental health functioning among Hispanic youth. Research on Hispanic youth mental health have reported high rates of depressive symptomatology and high rates of alcohol use among Hispanic adolescents but despite these findings, they have inadequate access to mental health services. This review highlights the need for better data to gain a better understanding of the health status of Hispanic youth and help develop preventive programs that addresses the need of this population. Improving access to health services, in particular mental health services, is also a crucial aspect.

Abstract
OBJECTIVE This study examined the role of English language use in the reported frequency of musculoskeletal pain among Hispanic and non-Hispanic White youth. METHOD This is a secondary data analysis using a cross-sectional sample of 12,189 Hispanic and non-Hispanic White adolescents recruited for the National Longitudinal Study of Adolescent to Adult Health. Respondents were classified into three groups: (a) English-speaking non-Hispanic Whites, (b) English-speaking Hispanics, and (c) Spanish-speaking Hispanics. RESULTS After controlling for body mass index and demographic, socioeconomic, and behavioral variables, Spanish-speaking Hispanics reported the least frequent musculoskeletal pain ( OR = 0.415, 95% CI [0.361, 0.477]; p < .001), followed by English-speaking Hispanics ( OR = 0.773, 95% CI [0.690, 0.865]; p < .001). CONCLUSION The experience of musculoskeletal pain is a physiological as well as a cultural phenomenon. IMPLICATIONS FOR PRACTICE Health care providers should consider the role of language use in reports of pain in Hispanic and non-Hispanic White adolescents.

Abstract
OBJECTIVE The purpose of this study was to examine the association of intergenerational education and country of birth with waist circumference, metabolic syndrome, and type 2 diabetes among older adult Latinos in the United States. METHODS We used cross-sectional data from the Sacramento Area Latino Study on Aging, a cohort of older adult Mexican-American Latinos (mean age = 70 years). At baseline, we measured waist circumference and assessed metabolic syndrome and diabetes according to established guidelines (N = 1,789). Participants were classified as US-born or foreign-born based on self-reported birth country. Participants reported their parents' education level (≥6 vs. <6 years) and their own educational attainment (≥12 vs. <12 years). RESULTS US-born participants who achieved high adult education, regardless of their parents' education, had 37% lower odds of type 2 diabetes compared to US-born participants with both low parental and personal education levels [e.g., multivariable-adjusted OR (parental low/adult high) = 0.63; 95% CI = 0.40, 0.99]. Among the foreign-born, only those with both high parental and high personal education levels had 55% lower odds of large waist circumference (OR = 0.45; 95% CI = 0.23, 0.88) compared to foreign-born participants with both low parental and personal education levels. CONCLUSIONS Intergenerational exposure to low education levels may increase central obesity and type 2 diabetes differentially among US-born and foreign-born Latinos.

Abstract
Obstructive sleep apnea (OSA) is an increasingly prevalent condition. A growing body of literature supports substantial racial disparities in the prevalence, risk factors, presentation, diagnosis, and treatment of this disease. Craniofacial structure among Asians appears to confer an elevated risk of OSA despite lower rates of obesity. Among African Americans, Native Americans, and Hispanics, OSA prevalence is increased, likely due in part to obesity. The burden of symptoms, particularly excessive daytime sleepiness, is higher among African Americans, although Hispanics more often report snoring. Limited data suggest that African Americans may be more susceptible to hypertension in the setting of OSA. While differences in genetic risk factors may explain disparities in OSA burden, no definitive genetic differences have yet been identified. In addition to disparities in OSA development, disparities in OSA diagnosis and treatment have also been identified. Increased severity of disease at diagnosis among African Americans suggests a delay in diagnosis. Treatment outcomes are also suboptimal among African Americans. In children, tonsillectomy is less likely to cure OSA and more commonly associated with complications in this group. Among adults, adherence to continuous positive airway pressure (CPAP) is substantially lower in African Americans. The reasons for these disparities, particularly in outcomes, are not well understood and should be a research priority.

Abstract
PURPOSE To explore whether contextual variables attenuate disparities in weight among 18,639 US children and adolescents aged 2 to 18 years participating in the National Health and Nutrition Examination Survey, 2001 to 2010. METHODS Disparities were assessed using the Symmetrized Rényi Index, a new measure that summarizes disparities in the severity of a disease, as well as the prevalence, across multiple population groups. Propensity score subclassification was used to ensure covariate balance between racial and ethnic subgroups and account for individual-level and contextual covariates. RESULTS Before propensity score subclassification, significant disparities were evident in the prevalence of overweight and/or obesity and the degree of excess weight among overweight/obese children and adolescents. After propensity score subclassification, racial/ethnic disparities in the prevalence and severity of excess weight were completely attenuated within matched groups, indicating that racial and ethnic differences were explained by social determinants such as neighborhood socioeconomic and demographic factors. CONCLUSIONS The limited overlap in covariate distributions between various racial/ethnic subgroups warrants further attention in disparities research. The attenuation of disparities within matched groups suggests that social determinants such as neighborhood socioeconomic factors may engender disparities in weight among US children and adolescents.

Abstract
Obesity is an escalating threat of pandemic proportions, currently affecting billions of people worldwide and exerting a devastating socioeconomic influence in industrialized countries. Despite intensive efforts to curtail obesity, results have proved disappointing. Although it is well recognized that obesity is a result of gene-environment interactions and that predisposition to obesity lies predominantly in our evolutionary past, there is much debate as to the precise nature of how our evolutionary past contributed to obesity. The "thrifty genotype" hypothesis suggests that obesity in industrialized countries is a throwback to our ancestors having undergone positive selection for genes that favored energy storage as a consequence of the cyclical episodes of famine and surplus after the advent of farming 10 000 years ago. Conversely, the "drifty genotype" hypothesis contends that the prevalence of thrifty genes is not a result of positive selection for energy-storage genes but attributable to genetic drift resulting from the removal of predative selection pressures. Both theories, however, assume that selection pressures the ancestors of modern humans living in western societies faced were the same. Moreover, neither theory adequately explains the impact of globalization and changing population demographics on the genetic basis for obesity in developed countries, despite clear evidence for ethnic variation in obesity susceptibility and related metabolic disorders. In this article, we propose that the modern obesity pandemic in industrialized countries is a result of the differential exposure of the ancestors of modern humans to environmental factors that began when modern humans left Africa around 70 000 years ago and migrated through the globe, reaching the Americas around 20 000 years ago. This article serves to elucidate how an understanding of ethnic differences in genetic susceptibility to obesity and the metabolic syndrome, in the context of historic human population redistribution, could be used in the treatment of obesity in industrialized countries.
