BMI Trajectories During the Transition to Older Adulthood: Persistent, Widening, or Diminishing Disparities by Ethnicity and Education?

Previous research has produced inconsistent results on whether education and ethnic disparities in BMI persist, widen, or diminish over time. We investigate how education and ethnicity, independently and conditionally, influence BMI trajectories during the transition to older adulthood. Employing random coefficient modeling, we analyzed 8 biennial waves of data (1992-2006) from the Health and Retirement Study, a nationally representative longitudinal study of individuals born between 1931 and 1941. After adjusting for health behaviors and health status, education and ethnic disparities in BMI persisted for most groups, but narrowed between high-educated white men and both low-educated Hispanic men and high-educated black men. As such, our findings generally support the persistent inequality interpretation. Therefore, even though interventions targeted at earlier points in the life course may be effective in reducing BMI disparities in later life, social and health policies directed at reducing obesity among older adults is also warranted

STRV -- A radiation hard RISC-V microprocessor for high-energy physics applications

While microprocessors are used in various applications, they are precluded from the use in high-energy physics applications due to the harsh radiation present. To overcome this limitation a microprocessor design must withstand high doses of radiation and mitigate radiation induced soft errors. A TMR protection scheme is applied to protect a RISC-V microprocessor core against these faults. The protection of the integrated SRAM by an independent scrubbing algorithm is discussed. Initial irradiation results and power consumption measurements of the radiation-resistant RISC-V microprocessor implemented in 65 nm CMOS technology are presented.Comment: TWEPP-2022 Proceeding

The intersection of school racial composition and student race/ethnicity on adolescent depressive and somatic symptoms

Effect of School Racial Composition on Trajectories of Depressive Symptoms from Adolescence Through Early Adulthood

We investigate the effect of high school racial composition, measured as percent of non-Hispanic white students, on trajectories of depressive symptoms from adolescence to early adulthood. We also explore whether the effect of school racial composition varies by respondent race/ethnicity and whether adult socioeconomic status mediates this relationship. We analyzed four waves of data from the National Longitudinal Study of Adolescent Health using 3-level linear growth models. We restricted our sample to respondents enrolled in grades 9-12 in 1994/5 who were interviewed at a minimum in Waves I and IV. This resulted in 10,350 respondents enrolled in 80 high schools in 1994/5 (5,561 whites, 2,030 blacks, 1,834 Hispanics, 738 Asians, and 187 of other race). As the percentage of white students increased at the high school respondents attended in 1994/5, blacks reported more depressive symptoms. This effect did not vary by age. In comparison, Asian and Hispanic respondents who attended predominantly white high schools had lower levels of depressive symptoms than their counterparts who attended predominantly minority schools, but they also experienced a slower decline in depressive symptoms through early adulthood. Adult SES mediated the relationship between high school racial composition and depressive symptoms for black, but not for Asian or Hispanic respondents. Our results suggest that high school racial composition is associated with trajectories of depressive symptoms through early adulthood, but the effect differs by respondents’ race/ethnicity. Racial/ethnic disparities in depressive symptoms during early adulthood may have their origins in adolescence

Accumulating Disadvantage Over the Life Course: Evidence From a Longitudinal Study Investigating the Relationship Between Educational Advantage in Youth and Health in Middle Age

Recent studies suggest the importance of examining cumulative risk or advantage as potential predictors of health over the life course. Researchers investigating the cumulative health effects of education, however, have mainly conceptualized education in years or degrees, often disregarding educational quality and access to educational opportunities that may place individuals on divergent academic trajectories. We investigate whether educational advantages in youth are associated with an individual\u27s health trajectory. We develop a novel index of educational advantage and employ random-intercept modeling using data from the National Longitudinal Survey of Youth. We find a widening health disparity in adulthood between respondents with greater and those with fewer educational advantages in youth. Further, among respondents with few educational advantages, blacks experience a greater health burden as they age compared to whites and Hispanics. These results suggest that differential access to educational advantages during youth may contribute to persisting health disparities in adulthood

Effect of School Racial Composition on Trajectories of Depressive Symptoms from Adolescence through Early Adulthood

Introduction: We investigate the effect of high school racial composition, measured as percent of non-Hispanic White students, on trajectories of depressive symptoms from adolescence to early adulthood. We also explore whether the effect of school racial composition varies by respondent race/ethnicity and if adult socio-economic status mediates this relationship. Methods: We analyzed four waves of data from the National Longitudinal Study of Adolescent Health using 3-level linear growth models. We restricted our sample to respondents enrolled in grades 9-12 in 1994/5 who were interviewed at a minimum in Waves I and IV. This resulted in 10,350 respondents enrolled in 80 high schools in 1994/5 (5,561 Whites, 2,030 Blacks, 1,834 Hispanics, 738 Asians, and 187 of other race). Results: As the percentage of White students increased at the high school respondents attended in 1994/5, Blacks reported more depressive symptoms. This effect did not vary by age. In comparison, Asian and Hispanic respondents who attended predominantly-White high schools had lower levels of depressive symptoms than their counterparts who attended predominantly-minority schools, but they also experienced a slower decline in depressive symptoms through early adulthood. Adult SES mediated the relationship between high school racial composition and depressive symptoms for Black, but not for Asian or Hispanic respondents. Discussion: Our results suggest that high school racial composition is associated with trajectories of depressive symptoms through early adulthood, but the effect differs by respondents\u27 race/ethnicity. Racial/ethnic disparities in depressive symptoms during early adulthood may have their origins in adolescence

Adolescent Loneliness and Health in Early Adulthood

The health consequence of loneliness in the early life course is an understudied topic in the sociological literature. Using data from Waves 1–3 of the National Longitudinal Study of Adolescent Health, we examine pre-disease pathways in the relationship between adolescent loneliness and early adult health. Our results indicate that loneliness during adolescence is associated with diagnosed depression, poorer adult self-rated health, and metabolic risk factors related to cardiovascular disease. High depressive symptoms and parent support are important pathways through which the health consequences of loneliness are exacerbated or offset. There is also evidence that lonely youth remain at higher risk for experiencing adult depression and poor self-rated health even in the presence of equivalent levels of parental support relative to non-lonely adolescents. Furthermore, lonely adolescent females are more vulnerable to reporting poor adult self-rated health and being overweight or obese in adulthood. In sum, our study demonstrates the importance of adolescent loneliness for elevating the risk of poor health outcomes in adulthood
