Household socioeconomic status modifies the association between neighborhood SES and obesity in a nationally representative sample of first grade children in the United States.

ABSTRACT: Both low family socioeconomic status (SES) and low neighborhood SES have been associated with higher levels of childhood obesity. However, little is known about how these two factors operate together. The purpose of this study was to determine if the association between neighborhood SES and obesity varies across household SES. We used the first-grade round of the Early Childhood Longitudinal Study, Kindergarten Class of 2011 (ECLS-K:2011). Household SES was defined based on income, education, and occupation. Neighborhood SES was defined by the percent of households living in poverty in the child's school district. Log-binomial regression models estimated the association between neighborhood SES and obesity and tested whether this association varied by household SES. We found the association between neighborhood SES and obesity varied significantly by household SES (p-interaction = 0.002). For children in the lowest tertile of neighborhood SES, prevalence of obesity was not statistically significantly different comparing children with low, middle or high household SES (Predicted probability (PP)lowest 0.20 (95% CI: 0.17, 0.23), PPmiddle 0.21 (95%CI: 0.18, 0.24), PPhighest 0.16 (95%CI: 0.12, 0.20)). Conversely, within the highest and the middle tertiles of neighborhood SES, children with high household SES have significantly lower prevalence of obesity compared to children with the lowest household SES (PP: 0.09 (95%CI: 0.07, 0.11) vs 0.19 (0.16, 0.21) and (PP: 0.07 (95%CI: 0.05, 0.09) vs 0.17 (0.13, 0.21) for highest vs lowest household SES in middle and high neighborhood SES, respectively). Hence, low-SES in either variable is enough to be associated with increased prevalence of obesity.

Project description:Despite increased awareness and concern about children with developmental disabilities wandering away from adult supervision, there is a paucity of research about elopement. This is the first study to examine and report the prevalence and correlates of elopement in a nationally representative sample of school-age children in the United States with an autism spectrum disorder (ASD) and/or cognitive impairment. Data were obtained from the CDC's "Pathways" Survey, a follow-up telephone survey of the parents of 4,032 children with a developmental condition. 3,518 children that had ASD, intellectual disability (ID), and/or developmental delay (DD) at the time of survey administration were included for analysis. Children were divided into three condition groups: ASD-only; ID/DD-only; ASD+ID/DD. Logistic regression analyses were used to compare the prevalence of elopement and rates of preventive measure use (barriers and/or electronic devices) across condition groups, and to examine the clinical and demographic correlates of elopement. T-tests were also performed to compare scores on the Children's Social Behavior Questionnaire (CSBQ) between wanderers and non-wanderers. Overall, 26.7% of children had reportedly eloped within the previous year, most commonly from public places. Children with ASD-only and ASD+ID/DD were more likely to have eloped than those with ID/DD-only. Across all groups, wanderers scored higher than non-wanderers on five out of six CSBQ subscales; they were more likely not to realize when there is danger, to have difficulty distinguishing between strangers and familiar people, to show sudden mood changes, to over-react to everything/everyone, to get angry quickly, to get lost easily, and to panic in new situations or if change occurs. Even after controlling for elopement history, parents of children in the ASD+ID/DD group were more likely than those in the other condition groups to report using physical or electronic measures to prevent wandering.

Project description:IntroductionSeveral studies reported the negative impact of elevated neutrophil/lymphocyte ratio (NLR) on outcomes in many surgical and medical conditions. Previous studies used arbitrary NLR cut-off points according to the average of the populations under study. There is no data on the average NLR in the general population. The aim of this study is to explore the average values of NLR and according to race in adult non-institutional United States individuals by using national data.MethodsThe National Health and Nutrition Examination Survey (NHANES) of aggregated cross-sectional data collected from 2007 to 2010 was analyzed; data extracted included markers of systemic inflammation (neutrophil count, lymphocyte count, and NLR), demographic variables and other comorbidities. Subjects who were prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. Adjusted linear regression models were used to examine the association between demographic and clinical characteristics and neutrophil counts, lymphocyte counts, and NLR.ResultsOverall 9427 subjects are included in this study. The average value of neutrophils is 4.3 k cells/mL, of lymphocytes 2.1k cells/mL; the average NLR is 2.15. Non-Hispanic Black and Hispanic participants have significantly lower mean NLR values (1.76, 95% CI 1.71-1.81 and 2.08, 95% CI 2.04-2.12 respectively) when compared to non-Hispanic Whites (2.24, 95% CI 2.19-2.28-p<0.0001). Subjects who reported diabetes, cardiovascular disease, and smoking had significantly higher NLR than subjects who did not. Racial differences regarding the association of smoking and BMI with NLR were observed.ConclusionsThis study is providing preliminary data on racial disparities in a marker of inflammation, NLR, that has been associated with several chronic diseases outcome, suggesting that different cut-off points should be set according to race. It also suggests that racial differences exist in the inflammatory response to environmental and behavioral risk factors.

Project description:There is considerable variation in alcohol use and problems across the United States, suggesting that systematic regional differences might contribute to alcohol involvement. Several neighborhood contextual factors may be important aspects of this "alcohol environment."Participants were 15,197 young adults (age 18 to 26) from Wave III of the National Longitudinal Study of Adolescent to Adult Health, a nationally representative U.S. survey. Measures of past-year alcohol use and problems were obtained via structured in-home interviews. Tract-level neighborhood contextual factors (density of on- and off-premises alcohol outlets, neighborhood disadvantage, rural vs. urban residence) were derived from census indicators and geocoded state-level alcohol outlet licenses. Multivariate logistic regression, ordered logistic regression, or negative binomial regression models, including age, sex, race, and household income as covariates, were fit to examine the relation of the neighborhood contextual factors with alcohol use and problems.The most consistent finding across 4 of the 5 measures of alcohol involvement was their association with neighborhood advantage; the active ingredient underlying this effect was primarily the proportion of educated residents in the neighborhood. The densities of alcohol outlets were associated with any alcohol use-they were not associated with binge drinking or alcohol problems, nor could they explain any of the neighborhood advantage effects. The influence of alcohol outlet densities on alcohol involvement did not differ for those above or below the legal age to purchase alcohol. Living in a rural versus an urban neighborhood was associated with a different alcohol use pattern characterized by a lower likelihood of any drinking, but among those who drank, consuming more alcohol per occasion.Living in a more advantaged and educated urban neighborhood with greater densities of bars and restaurants is associated with greater alcohol involvement among 18- to 26-year-olds in the United States.
