American Indian, Alaska Native, Native Hawaiian, and Pacific Islander Children's Body Mass Index: Diminished Returns of Parental Education and Family Income.

ABSTRACT:

Background

Socioeconomic status (SES) is associated with several health-related outcomes, such as obesity and body mass index (BMI). However, we do not know whether SES is associated differently with children's BMI from American Indian and Alaska Native and Native Hawaiian and Pacific Islander (AIAN/NHPI) families when compared to non-Hispanic White (NHW) families.

Aim

To compare AIAN/NHPI and NHW families for associations between parental education, family income, and children's BMI in the United States (U.S).

Methods

This cross-sectional investigation used the Adolescent Brain Cognitive Development (ABCD) study data. Participants (n = 8580) included 63 AIAN/NHPI and 8517 NHW children between ages 9 and 10. The independent variables were parental education and family income. The primary outcome was BMI. Race was the moderator. Age, sex, and family structure were covariates. Mixed-effects regression models were used for data analysis.

Results

In the pooled sample, higher parental education and family income were associated with lower children's BMI. We found interactions between race and parental education and family income indicating weaker associations between parental education and family income and children's BMI in AIAN/NHPI families than in NHW families.

Conclusion

The salience of parental education and family income as social determinants of children's BMI is diminished for AIAN/NHPI families than NHW families. As a result, AIAN/NHPI children with high SES remain at risk for high BMI, while high-SES NHW children show the lowest BMI. Future research should test if obesogenic environments, food options, and physical activity-friendly neighborhoods can explain higher-than-expected BMI in high-SES AIAN/NHPI children. In other terms, more research is needed to understand if residential segregation, discrimination, and historical trauma explain the observed differences in the social patterning of childhood BMI in AIAN/NHPI and NHW communities.

Project description:Objective: The aim of this study was to describe current measurement of health disparities for Asian American, Native Hawaiian, and Pacific Islander (AANHPI) populations and subgroups across U.S. states. Methods: State department of health websites were searched for publicly available online reports and interactive databases denoted as state health or minority health assessments. Sources were examined to determine whether health metrics stratified by any racial/ethnic groups included the AANHPI aggregate population or subgroups. The number and frequency of AANHPI population designations were tabulated, as were the proportion of states that included AANHPIs in stratified metrics in four domains across the life span and the median number of metrics (1) stratified by any racial/ethnic group and (2) including AANHPI populations. A Pearson correlation coefficient assessed the association between the proportion of AANHPIs in state populations and the proportion of state metrics that included AANHPIs in the stratification. Results: States used 17 AANHPI population descriptors. Of 49 states stratifying health metrics by race/ethnicity, 34 included AANHPI populations and 2 included disaggregated AANHPI subgroups in ≥1 metric. The proportion of states that included AANHPI populations in stratification ranged from 57% for maternal–infant health to 69% for adult health, and by metric groups within domains, the proportion ranged from 14% for maternal mortality to 100% for marital or head of household status. The median number of metrics reported for AANHPI populations was lower than the median number reported for other racial/ethnic groups in adult, maternal–infant, and child and adolescent health domains. The proportion of state metrics that included AANHPIs in racial/ethnic stratification was not correlated with the proportion of AANHPIs in state populations (r=0.30). Conclusions and Implications for Health Equity: AANHPIs were substantially underrepresented in state health equity data, with rare subgroup disaggregation. Reducing disparities and inequities affecting AANHPI health in the United States requires improved and equitable data.

Project description:BackgroundAsian Americans and Native Hawaiians and other Pacific Islanders have suboptimal human papillomavirus (HPV) vaccination and cancer screening rates. Asian Americans and NHPIs are often aggregated, masking disparities characterized by varying colonization and immigration patterns and cultural and religious beliefs between populations and ethnicities. We examined the incidence of HPV-associated cancers across disaggregated Asian American and NHPI ethnicities.MethodsUsing the Surveillance, Epidemiology, and End Results Detailed Asian/Pacific Islander database, we calculated 1990 to 2014 sex-specific, age-standardized HPV-associated cancer incidence of cervical carcinoma, oropharyngeal squamous cell carcinoma (SCC), vulvar SCC, vaginal SCC, anal SCC, and penile SCC by ethnicity: Asian Indian and Pakistani, Chinese, Filipino, Japanese, Kampuchean, Korean, Laotian, Native Hawaiian, other Pacific Islander, and Vietnamese. Trends by calendar period (1990 to 1996, 1997 to 2002, 2003 to 2008, 2009 to 2014) were estimated using Joinpoint regression.ResultsThe most common HPV-associated cancer was cervical carcinoma in women and oropharyngeal SCC in men. During 1990 to 2014, cervical carcinoma incidence per 100 000 ranged from 4.5 (Asian Indian and Pakistani) to 20.7 (Laotian). Cervical carcinoma incidence only statistically significantly declined for Asian Indian and Pakistani, Filipino, Korean, Laotian, and Vietnamese women (range = 19.9% to 44.1% decline per period). Among men, oropharyngeal SCC incidence per 100 000 ranged from 1.1 (Chinese) to 5.1 (Native Hawaiian). Oropharyngeal SCC incidence only statistically significantly increased (31.0% increase per period) for Japanese men. Heterogeneity across ethnicities were observed for other cancer sites.ConclusionsHPV-associated cancer incidence varied widely between Asian Americans and NHPIs and by ethnicity, underscoring the need for improved data capture of ethnic groups in research and more tailored interventions to better address health disparities between Asian American and NHPI populations.

Project description:BackgroundObesity prevalence remains high among children of Pacific Islander (PI) origin, Filipino (FI), and American Indian/Alaska Native (AIAN) origins in the United States. While school nutrition policies may help prevent and reduce childhood obesity, their influences specifically among PI, FI, and AIAN children remain understudied. We evaluated the association of the California (CA) state school nutrition policies for competitive food and beverages and the federal policy for school meals (Healthy, Hunger-Free Kids Act of 2010 (HHFKA 2010)) with overweight/obesity among PI, FI, and AIAN students.Methods and findingsWe used an interrupted time series (ITS) design with FitnessGram data from 2002 to 2016 for PI (78,841), FI (328,667), AIAN (97,129), and White (3,309,982) students in fifth and seventh grades who attended CA public schools. Multilevel logistic regression models estimated the associations of the CA school nutrition policies (in effect beginning in academic year 2004 to 2005) and HHFKA 2010 (from academic year 2012 to 2013) with overweight/obesity prevalence (above the 85 percentile of the age- and sex-specific body mass index (BMI) distribution). The models were constructed separately for each grade and sex combination and adjusted for school district-, school-, and student-level characteristics such as percentage of students eligible for free and reduced price meals, neighborhood income and education levels, and age. Across the study period, the crude prevalence of overweight/obesity was higher among PI (39.5% to 52.5%), FI (32.9% to 36.7%), and AIAN (37.7% to 45.6%) children, compared to White (26.8% to 30.2%) students. The results generally showed favorable association of the CA nutrition policies with overweight/obesity prevalence trends, although the magnitudes of associations and strengths of evidence varied among racial/ethnic subgroups. Before the CA policies went into effect (2002 to 2004), overweight/obesity prevalence increased for White, PI, and AIAN students in both grades and sex groups as well as FI girls in seventh grade. After the CA policies took place (2005 to 2012), the overweight/obesity rates decreased for almost all subgroups who experienced increasing trends before the policies, with the largest decrease seen among PI girls in fifth grade (before: log odds ratio = 0.149 (95% CI 0.108 to 0.189; p < 0.001); after: 0.010 (-0.005 to 0.025; 0.178)). When both the CA nutrition policies and HHFKA 2010 were in effect (2013 to 2016), declines in the overweight/obesity prevalence were seen among White girls and FI boys in fifth grade. Despite the evidence of the favorable association of the school nutrition policies with overweight/obesity prevalence trends, disparities between PI and AIAN students and their White peers remained large after the policies took place. As these policies went into effect for all public schools in CA, without a clear comparison group, we cannot conclude that the changes in prevalence trends were solely attributable to these policies.ConclusionsThe current study found evidence of favorable associations of the state and federal school nutrition policies with overweight/obesity prevalence trends. However, the prevalence of overweight/obesity continued to be high among PI and AIAN students and FI boys. There remain wide racial/ethnic disparities between these racial/ethnic minority subgroups and their White peers. Additional strategies are needed to reduce childhood obesity and related disparities among these understudied racial/ethnic populations.
