Sex/gender differences in cognitive trajectories vary as a function of race/ethnicity.

ABSTRACT: Introduction:The present study sought to determine whether cognitive trajectories differ between men and women across and within racial/ethnic groups.

Methods:Participants were 5258 non-Hispanic White (NHW), Black, and Hispanic men and women in the Washington/Hamilton Heights-Inwood Columbia Aging Project who were administered neuropsychological tests of memory, language, and visuospatial abilities at 18- to 24-month intervals for up to 25 years. Multiple-group latent growth curve modeling examined trajectories across sex/gender by race/ethnicity.

Results:After adjusting for age and education, the largest baseline differences were between NHW men and Hispanic women on visuospatial and language, and between NHW women and Black men on memory. Memory and visuospatial decline was steeper for Black women compared with Hispanic men and NHW women, respectively.

Discussion:This study takes an important first step in understanding interactions between race/ethnicity and sex/gender on cognitive trajectories by demonstrating variability in sex/gender differences across race/ethnicity.

Project description:BACKGROUND:National heart failure (HF) hospitalization rates have not been appropriately age standardized by sex or race/ethnicity. Reporting hospital utilization trends by subgroup is important for monitoring population health and developing interventions to eliminate disparities. METHODS AND RESULTS:The National Inpatient Sample (NIS) was used to estimate the crude and age-standardized rates of HF hospitalization between 2002 and 2013 by sex and race/ethnicity. Direct standardization was used to age-standardize rates to the 2000 US standard population. Relative differences between subgroups were reported. The national age-adjusted HF hospitalization rate decreased 30.8% from 526.86 to 364.66 per 100?000 between 2002 and 2013. Although hospitalizations decreased for all subgroups, the ratio of the age-standardized rate for men compared with women increased from 20% greater to 39% (P trend=0.002) between 2002 and 2013. Black men had a rate that was 229% (P trend=0.141) and black women, 240% (P trend=0.725) with reference to whites in 2013 with no significant change between 2002 and 2013. Hispanic men had a rate that was 32% greater in 2002 and the difference narrowed to 4% (P trend=0.047) greater in 2013 relative to whites. For Hispanic women, the rate was 55% greater in 2002 and narrowed to 8% greater (P trend=0.004) in 2013 relative to whites. Asian/Pacific Islander men had a 27% lower rate in 2002 that improved to 43% (P trend=0.040) lower in 2013 relative to whites. For Asian/Pacific Islander women, the hospitalization rate was 24% lower in 2002 and improved to 43% (P trend=0.021) lower in 2013 relative to whites. CONCLUSIONS:National HF hospitalization rates have decreased steadily during the recent decade. Disparities in HF burden and hospital utilization by sex and race/ethnicity persist. Significant population health interventions are needed to reduce the HF hospitalization burden among blacks. An evaluation of factors explaining the improvements in the HF hospitalization rates among Hispanics and Asian/Pacific Islanders is needed.

Project description:BackgroundExamining social networks, characterized by interpersonal interactions across family, peer, school, and neighborhoods, offer alternative explanations to suicidal behaviors and shape effective suicide prevention. This study examines adolescent social networks predicting suicide ideation and attempt trajectories transitioning to adulthood, while revealing differences across racial/ethnic, sex, sexual identity, and socioeconomic status.MethodsParticipants included 9421 high school students (Mage = 15.30 years; 54.58% females, baseline) from Waves I-IV of the National Longitudinal Study of Adolescent to Adult Health, 1994-2008. Latent class growth analyses were conducted to identify suicide ideation and attempt trajectories. Multivariate multinomial logistic regressions examined the relationships between social network characteristics during adolescence and suicidal trajectories. Interaction terms between social networks and sociodemographic characteristics were included to test moderation effects.ResultsThree suicidal ideation trajectories (low-stable, high-decreasing, moderate-decreasing-increasing) and two suicide attempt trajectories (low-stable, moderate-decreasing) were identified. Greater family cohesion significantly reduced the probability of belonging to high-decreasing (Trajectory 2) and moderate-decreasing-increasing (Trajectory 3) suicidal ideation trajectories, and moderate-decreasing (Trajectory 2) suicide attempt trajectory. Race/ethnicity, sex, and sexual identity significantly moderated the associations between social networks (household size, peer network density, family cohesion, peer support, neighborhood support) and suicidal trajectories.ConclusionsSocial networks during adolescence influenced the odds of belonging to distinct suicidal trajectories. Family cohesion protected youth from being in high-risk developmental courses of suicidal behaviors. Social networks, especially quality of interactions, may improve detecting adolescents and young adults at-risk for suicide behaviors. Network-based interventions are key to prevent suicidal behaviors over time and suicide intervention programming.

Project description:Using social-cognitive career theory, we identified the experiential sources of learning that contribute to research self-efficacy beliefs, outcome expectations, and science identity for culturally diverse undergraduate students in science, technology, engineering, and math (i.e., STEM) majors. We examined group differences by race/ethnicity and gender to investigate potential cultural variations in a model to explain students' research career intentions. Using a sample of 688 undergraduate students, we ran a series of path models testing the relationships between the experiential sources, research self-efficacy beliefs, outcome expectations, and science identity to research career intentions. Findings were largely consistent with our hypotheses in that research self-efficacy and outcome expectancies were directly and positively associated with research career intentions and the associations of the experiential sources to intentions were mediated via self-efficacy. Science identity contributed significant though modest variance to research career intentions indirectly via its positive association with outcome expectations. Science identity also partially mediated the efficacy-outcome expectancies path. The experiential sources of learning were associated in expected directions to research self-efficacy with 3 of the sources emerging as significantly correlated with science identity. An unexpected direct relationship from vicarious learning to intentions was observed. In testing for group differences by race/ethnicity and gender in subsamples of Black/African American and Latino/a students, we found that the hypothesized model incorporating science identity was supported, and most paths did not vary significantly across four Race/Ethnicity × Gender groups, except for 3 paths. Research and practice implications of the findings for supporting research career intentions of culturally diverse undergraduate students are discussed.
