County-Level Clustering and Characteristics of Repeat Versus First Teen Births in the United States, 2015-2017.

ABSTRACT: PURPOSE:Approximately 16% of U.S. births to women aged 15-19 years are repeat (second or higher order) births. Repeat teen mothers are at elevated risk for poor perinatal outcomes. Geographic clustering and correlates of repeat teen birth are unknown. METHODS:Data from birth certificates on N = 629,939 teen births in N = 3,108 U.S. counties in 2015-2017 were merged with data on county-level demographic, socioeconomic, and health provider characteristics. We identified contiguous clusters of counties with significantly elevated rates of first teen births only, repeat teen births, both, or neither between 2015 and 2017 and compared demographic, socioeconomic, and medical provider characteristics of counties between 2010 and 2016 in each cluster type. RESULTS:A total of 193 counties (6.21%) had high rates of repeat births only; 504 (16.22%) had high rates of first teen birth only; 991 (31.89%) had high rates of both repeat and first teen births; and 1,420 (45.69%) had neither. Counties with high repeat (vs. first only) birth rates had higher rates of poverty and unemployment, higher levels of income inequality, lower high school graduation rates, a higher share of racial and ethnic minority residents, fewer publicly funded family planning clinics per capita, and more women receiving contraceptive services at publicly funded clinics. CONCLUSIONS:First and repeat teen births cluster in differentially resourced geographic areas. Counties with high repeat teen birth rates have lower socioeconomic conditions than counties with high rates of first teen births only. These counties are more reliant on publicly funded family planning clinics but have fewer of them per capita.

Project description:Importance:Progress against premature death due to noncommunicable chronic disease (NCD) has stagnated. In the United States, county-level variation in NCD premature mortality has widened, which has impeded progress toward mortality reduction for the World Health Organization (WHO) 25 × 25 target. Objectives:To estimate variations in county-level NCD premature mortality, to investigate factors associated with mortality, and to present the progress toward achieving the WHO 25 × 25 target by analyzing the trends in mortality. Design, Setting, and Participants:This cross-sectional study focused on NCD premature mortality and its factors from 3109 counties using US mortality data for cause of death from the Centers for Disease Control and Prevention WONDER databases and county-level characteristics data from multiple databases. Data were collected from January 1, 1999, through December 31, 2017, and analyzed from April 1 through October 28, 2019. Exposures:County-level factors, including demographic composition, socioeconomic features, health care environment, and population health status. Main Outcomes and Measures:Variations in county-level, age-adjusted NCD mortality in the US residents aged 25 to 64 years and associations between mortality and the 4 sets of county-level factors. Results:A total of 6 794 434 deaths due to NCD were recorded during the study period (50.58% women; 16.49% aged 65 years or older). Mortality decreased by 4.30 (95% CI, -4.54 to -4.08) deaths per 100 000 person-years annually from 1999 to 2010 (P < .001) and decreased annually at a rate of 0.90 (95% CI, -1.13 to -0.73) deaths per 100 000 person-years annually from 2010 to 2017 (P < .001). Mortality in the county with the highest mortality was 10.40 times as high as that in the county with the lowest mortality (615.40 vs 59.20 per 100 000 population) in 2017. Geographic inequality was decomposed by between-state and within-state differences, and within-state differences accounted for most inequality (57.10% in 2017). County-level factors were associated with 71.83% variation in NCD mortality. Association with intercounty mortality was 19.51% for demographic features, 23.34% for socioeconomic composition, 16.40% for health care environment, and 40.75% for health-status characteristics. Conclusions and Relevance:Given the stagnated trend of decline and increasing variations in NCD premature mortality, these findings suggest that the WHO 25 × 25 target appears to be unattainable, which may be related to broad failure by United Nations members to follow through on commitments of reducing socioeconomic inequalities. The increasing inequalities in mortality are alarming and warrant expanded multisectoral efforts to ameliorate socioeconomic disparities.

Project description:ObjectiveTo determine which county-level social, economic, demographic, epidemiologic and access to care factors are associated with Latino/non-Latino White disparities in prevalence of diagnosed HIV infection.Methods and findingsWe used 2016 county-level prevalence rates of diagnosed HIV infection rates for Latinos and non-Latino Whites obtained from the National HIV Surveillance System and factors obtained from multiple publicly available datasets. We used mixed effects Poisson modeling of observed HIV prevalence at the county-level to identify county-level factors that explained homogeneous effects across race/ethnicity and differential effects for Latinos and NL-Whites. Overall, the median Latinos disparity in HIV prevalence is 2.4; 94% of the counties have higher rates for Latinos than non-Latinos, and one-quarter of the counties' disparities exceeded 10. Of the 41 county-level factors examined, 24 showed significant effect modification when examined individually. In multi-variable modeling, 11 county-level factors were found that significantly affected disparities. Factors that increased disparity with higher, compared to lower values included proportion of HIV diagnoses due to injection drug use, percent Latino living in poverty, percent not English proficient, and percent Puerto Rican. Latino disparities increased with decreasing percent severe housing, drug overdose mortality rate, percent rural, female prevalence rate, social association rate, percent change in Latino population, and Latino to NL-White proportion of the population. These factors while significant had minimal effects on diminishing disparity, but did substantially reduce the variance in disparity rates.ConclusionsLarge differences in HIV prevalence rates persist across almost all counties even after controlling for county-level factors. Counties that are more rural, have fewer Latinos, or have lower NL-White prevalence rates tend to have higher disparities. There is also higher disparity when community risk is low.

Project description:U.S. Latino and foreign-born populations show lower child maltreatment report (CMR) rates despite their low socioeconomic positions, perhaps due to protective cultural factors within these populations. However, discriminatory Immigration and Customs Enforcement (ICE) activities may attenuate such protection. We examined how ethnic and foreign-born compositions and local ICE activities were associated with community CMR rates, overall and within racial/ethnic groups (i.e., White, Black, Latino), and how these associations changed over time. We used national county-level data linking multiple administrative/archival data sources (i.e., CMR, Census, and ICE data) longitudinally for 2015 to 2018 across the United States. Multilevel (county-years, counties, and states) models estimated how percentages of Latino, percentages of foreign-born, and ICE arrest rates were related to overall and race/ethnicity-specific CMR rates among counties while adjusting for a range of demographic, socioeconomic, child care burden, health insurance, residential mobility, and urbanicity factors. Higher percentages of foreign-born residents within counties were significantly associated with lower CMR rates, both overall and within all racial/ethnic groups. These protective associations became significantly stronger over the study period. Higher percentages of Latino residents were significantly associated with lower total and White CMR rates but not with Black or Latino CMR rates. The interaction between the percentage of Latino residents and year was not significant. ICE arrest rates showed no significant associations with CMR rates. Our findings suggest that communities with more foreign-born and Latino residents may be more protective against CMRs. While the foreign-born and Latino concentrations were both independently predictive of decreased CMR rates, the protective associations of the foreign-born concentration were more consistent within racial/ethnic groups and grew stronger over time. These findings suggest the need to investigate community-level protective mechanisms that may explain these results. The null findings for ICE activity also require further research with alternative measures of discriminatory state action.
