Project description:BackgroundDespite increased attention on the links between poverty and the health and wellbeing of youth, few have attempted to understand the physiological consequences associated with different forms of economic disadvantage among Latina/o children. The present study begins to address this gap by (1) examining whether different forms of economic disadvantage were related to telomere length for Latina/o children and (2) determining whether parents' nativity shapes economic disadvantage-telomere length relationships.MethodsData were drawn from the Fragile Families and Child Wellbeing Study, a longitudinal, stratified multistage probability sample of couples and children in 20 large US cities. The sample consisted of 417 Latina/o children and their parents that were followed from birth to age 9. Ordinary least squares regressions were used to examine relationships between economic disadvantage and telomere length.ResultsFindings revealed that poverty status was not significantly related to telomere length, whereas some forms of material hardship were shown to play a role in the risk of premature cellular aging. More specifically, medical hardship and difficulty paying bills were associated with shorter telomere length at age 9. Results also provide minimal evidence economic disadvantage-telomere length patterns varied by parents' nativity. Only medical hardship was related to shorter telomere length at age 9 for children with at least one foreign-born parent.ConclusionOverall, results indicate that the risk of premature cellular aging depends on the measure of economic disadvantage under investigation. Findings from this study can inform targeted strategies designed to reduce the deleterious consequences associated with economic deprivation.

Project description:Purpose: The purpose of this study was to examine how sexual orientation in adolescence and young adulthood was linked to diabetes risk. Methods: Data were drawn from the 1994-2008 National Longitudinal Study of Adolescent to Adult Health. The baseline sample included 4330 girls and 3510 boys ages 12-18. Guided by the life course approach, we considered both the timing and continuity of sexual orientation-broadly defined by sexual identity, sexual attraction, sexual contact, and romantic/sexual relationships-by differentiating respondents into four categories: sexual minority in both adolescence and adulthood, sexual minority in adulthood only, sexual minority in adolescence only, and heterosexual in both adolescence and young adulthood. Diabetes was identified using A1c and glucose biomarkers and self-reports of diabetes diagnosis or medication use. Results: Results from logistic regression models indicated that in comparison with their continuously heterosexual counterparts, respondents reporting sexual minority status in adulthood only or continuously in both adolescence and adulthood had higher diabetes risk in adulthood. However, respondents reporting sexual minority status in adolescence only were not different in diabetes risk in adulthood. The association between diabetes risk and continuous sexual minority status was stronger among women than among men. Conclusions: Sexual minority health disparities emerge early in the life course during adolescence and young adulthood. These findings highlight the importance of designing and implementing policies and public programs to alleviate minority stress early in life to reduce health disparities.

Project description:Material hardship, or difficulty affording basic resources such as food, housing, utilities, and health care, increases children's risk for internalizing problems. The uncinate fasciculus (UNC) and two of the gray matter regions it connects-the orbitofrontal cortex (OFC) and amygdala-may play important roles in the neural mechanisms underlying these associations. We investigated associations among material hardship, UNC microstructure, OFC and amygdala structure, and internalizing symptoms in children. Participants were 5-9-year-old children (N = 94, 61% female) from socioeconomically diverse families. Parents completed questionnaires assessing material hardship and children's internalizing symptoms. High-resolution, T1-weighted magnetic resonance imaging (n = 51), and diffusion tensor imaging (n = 58) data were acquired. UNC fractional anisotropy (FA), medial OFC surface area, and amygdala gray matter volume were extracted. Greater material hardship was significantly associated with lower UNC FA, smaller amygdala volume, and higher internalizing symptoms in children, after controlling for age, sex, and family income-to-needs ratio. Lower UNC FA significantly mediated the association between material hardship and internalizing symptoms in girls but not boys. These findings are consistent with the notion that material hardship may lead to altered white matter microstructure and gray matter structure in neural networks critical to emotion processing and regulation.

Project description:ObjectivePoor sleep poses negative health consequences for youth, yet few longitudinal actigraphy studies have examined basic developmental trends in sleep across adolescents' transition to young adulthood. In this longitudinal actigraphy study, stability of individual differences and trajectories of sleep during and after high school were examined. The degree to which sleep trajectories differed by college attendance status was also studied.MethodsA total of 343 youth with Asian, Latino, and European American backgrounds completed eight days of wrist actigraphy at two-year intervals in Wave 1 (n = 295, Mage = 16.39), Wave 2 (n = 211 including 34 new participants to refresh the sample, Mage = 18.31), and Wave 3 (n = 144, Mage = 20.29). Sleep duration, efficiency, and latency were estimated for weekdays and weekends. Intra-individual variability in duration across nights was also obtained.ResultsSleep parameters were correlated modestly between Wave 1 and Wave 2, but not correlated between Wave 1 and Wave 3, indicating modest shorter-term and little longer-term stability of individual differences. Multilevel growth models demonstrated declines in weekday sleep duration and efficiency across high school and post-high school years. Intra-individual variability in duration increased over the years. Latency trajectories changed more for non-college attendees compared with college attendees.ConclusionsOverall the findings suggest developmental trends of worsening sleep during adolescents' transition to young adulthood. Interventions to improve sleep may need to target specific issues faced by youth at that particular period in their lives.

Project description:Zeolites are key materials in both basic research and industrial applications. However, their synthesis is neither diverse nor applicable to labile frameworks because classical procedures require harsh hydrothermal conditions, whereas post-synthesis methods are limited to a few suitable parent materials. Remaining frameworks can fail due to amorphization, dissolution, and other decomposition processes. Nevertheless, stopping degradation at intermediate structures could yield new zeolites. Here, by optimizing the design and synthesis parameters of the parent zeolite IWV, we "caught" a new, highly crystalline, and siliceous zeolite during its degradation. IWV seed-assisted crystallization followed by gentle transformation into the water-alcohol system yielded the highly crystalline daughter zeolite IPC-20, whose structure was solved by precession-assisted three-dimensional electron diffraction. Without additional requirements, as in conventional (direct or post-synthesis) strategies, our approach may be applied to any chemically labile material with a staged structure.

Project description:ObjectiveSleep is unequally distributed in the US population. People with low socioeconomic status report worse quality and shorter sleep than people with high socioeconomic status. Past research hypothesized that a potential reason for this link could be exposure to material hardship. This study examines the associations between several material hardships and sleep outcomes.MethodsWe use population-representative cross-sectional data (n = 730) from the Michigan Recession and Recovery Study collected in 2013 and examine the associations between 6 indicators of material hardship (employment instability, financial problems, housing instability, food insecurity, forgone medical care, and the total number of material hardships reported) and 3 sleep outcomes (short sleep, sleep problems, and nonrestorative sleep). We build multivariable logistic regression models controlling for respondents' characteristics and light pollution near their residence.ResultsIn unadjusted models, all material hardships were associated with negative sleep outcomes. In adjusted models, forgone medical care was a statistically significant predictor of nonrestorative sleep (average marginal effect 0.16), as was employment instability (average marginal effect 0.12). The probability of sleep problems and nonrestorative sleep increased with a greater number of hardships overall (average marginal effects of .02 and .05, respectively). We found marginally statistically significant positive associations between food insecurity and short sleep and sleep problems.ConclusionsThis study finds that, except when considering foregone medical care, employment instability, and total count of material hardships, associations between material hardship and negative sleep outcomes are not statistically significant after adjusting for a robust set of sociodemographic and health characteristics.

Project description:In the current study, we examined a moderated mediation model using the risk and resilience framework. Specifically, the impact of family material hardship on adolescent problem behaviors was examined in a Chinese sample; we used the family stress model framework to investigate parental depression and negative parenting as potential mediators of the relation between family material hardship and adolescents' problem behaviors. In addition, based on resilience theory, we investigated adolescents' resilience as a potential protective factor in the development of their internalizing and externalizing problems. Participants included 1,419 Chinese adolescents (mean age = 15.38 years, SD = 1.79) and their primary caregivers. After controlling for covariates (age, gender, location of family residence, and primary caregiver), we found that parental depression and negative parenting mediated the association between family material hardship and adolescents' problem behaviors. Furthermore, the adolescent resilience moderated the relationship between negative parenting and internalizing problems in a protective-stabilizing pattern; in addition, a protective-reactive pattern also emerged when adolescent resilience was examined as a moderator of the relationship between negative parenting and externalizing problems. These findings contribute to a comprehensive understanding of the mechanisms of risk and resilience in youth development. Moreover, the findings have important implications for the prevention of adolescent problem behaviors.

Project description:American policymakers have long focused on work as a key means to improve economic wellbeing. Yet, work has become increasingly precarious and polarized. This precarity is manifest in low wages, but also in unstable and unpredictable work schedules that often vary significantly week-to-week with little advance notice. We draw on new survey data from The Shift Project on 37,263 hourly retail and food service workers in the United States. We assess the association between routine unpredictability in work schedules and household material hardship. Using both cross-sectional models and panel models, we find that workers who receive shorter advanced notice, those who work on-call, those who experience last minute shift cancellation and timing changes, and those with more volatile work hours are more likely to experience hunger, residential, medical, and utility hardships as well as more overall hardship. Just-in-time work schedules afford employers a great deal of flexibility, but at a heavy cost to workers' economic security.

Project description:The New York City (NYC) Longitudinal Study of Wellbeing, or "Poverty Tracker," is a survey of approximately 2300 NYC residents. Its purpose is to provide a multidimensional and dynamic understanding of economic disadvantage in NYC. Measures of disadvantage were collected at baseline and a 12-month follow-up, and include 3 types of disadvantage: 1) income poverty, using a measure on the basis of the new Supplemental Poverty Measure; 2) material hardship, including indicators of food insecurity, housing hardship, unmet medical needs, utility cutoffs, and financial insecurity; and 3) adult health problems, which can drain family time and resources. In this article initial results for NYC families with children younger than the age of 18 years are presented. At baseline, 56% of families with children had 1 or more type of disadvantage, including 28% with income poverty, 39% with material hardship, and 17% with an adult health problem. Even among nonpoor families, 33% experienced material hardship and 14% reported an adult health problem. Two-thirds of all families faced disadvantage at either baseline or follow-up, with 46% experiencing some kind of disadvantage at both time points. Respondents with a college education were much less likely to face disadvantage. Even after adjusting for educational attainment and family characteristics, the families of black and Hispanic respondents had increased rates of disadvantage. Considering income poverty alone the extent of disadvantage among families with children in NYC is greatly understated. These results suggest that in addition to addressing income poverty, policymakers should give priority to efforts to reduce material hardship and help families cope with chronic physical or mental illness. The need for these resources extends far above the poverty line.

Project description:Unintended pregnancies disproportionately occur among teenage women, yet little is known about the determinants of pregnancy desire among this group. We use a comprehensive baseline survey and weekly data on pregnancy desires to investigate which unmarried 18-20 year-old women want a pregnancy, want to avoid pregnancy, and report consistent pregnancy desire and disinclination. Variables that positively predict pregnancy desire generally negatively predict desire to avoid pregnancy. While most young women have no desire and strong disinclination in most weeks, childhood receipt of public assistance is a strong predictor of wanting pregnancy and not wanting to avoid it. Comparing nested models suggests that the effects of childhood disadvantage operate through social environments where early pregnancy is less stigmatized. Young women in serious relationships, who are depressed, and who are not pursuing post-secondary education have more desire for pregnancy and less disinclination, but little of childhood disadvantage is mediated by these factors.
