Abstract P194: Psychosocial Stressors And Cardiovascular Disease Risk Factors In Young African American Women: A Systematic Review
Bibliographic record
Abstract
Background: Emerging evidence suggests that psychosocial factors are related to morbidity and mortality due to cardiovascular disease (CVD). African American women experience a unique multitude of psychosocial stressors, including racism, discrimination, poverty, neighborhood stress, anxiety, and depression. The impact of these stressors on CVD risk in African American women during early adulthood (age 19-24 years) is limited. Objective: In this systematic review, we synthesized and evaluated the existing evidence on the relationship between psychosocial stress and CVD risk in young adult African American women. Methods: We conducted a comprehensive search of the literature in PubMed, APA PsycINFO, and CINAHL for studies published between January 1975 and May 2020 that examined psychosocial stress and CVD risk factors in young adult African American women. Eligible studies measured at least one psychosocial stress exposure, a CVD risk factor, or subclinical CVD outcome (e.g., body mass index, blood pressure, carotid intima-media thickness), and included African American women age 19-24 years or reported sex-stratified analyses. We excluded reviews, editorials, case studies, and gray literature. Two reviewers independently screened studies for eligibility and appraised the quality of the included studies using the Newcastle-Ottawa Scale. Results: The literature search yielded 1,100 potentially relevant articles for review. Of these, we identified nine studies that met our inclusion criteria: six cross-sectional and three prospective cohort studies. The mean age of participants ranged from 19 to 22 years. Of the nine studies, eight found that stress (i.e., perceived stress, racial discrimination, internalized racism, depression) was related to higher body mass index and blood pressure. In one longitudinal study, a greater frequency of everyday discrimination was associated with a nearly 2-fold higher odds of excessive weight gain (>40 pounds) during pregnancy. Overall, the majority of studies (n=6) were rated as excellent ; the remainder were good and fair. The lowest risk of bias was the selection and outcome measurement. Conclusion: This systematic review found sufficient evidence to support a relationship between psychosocial stress and CVD risk factors in young adult African American women. However, future studies that follow women from childhood to early adulthood are needed to gain a better understanding of the impact of psychosocial stress on the progression of CVD risk. Further investigation on specific stressors relevant to early adulthood, including self-identity and social role stress, are needed to understand the full extent to which psychosocial stress impacts CVD risk in young African American women.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
