Abstract MP77: Perceived Stress From Childhood to Young Adulthood and Cardiometabolic Endpoints in Young Adulthood: A Longitudinal Study of the Southern California Children’s Health Study

Abstract

The longitudinal impact of perceived stress on the risk of cardiometabolic disease has not been comprehensively evaluated among children and young adults. We hypothesized that patterns of perceived stress from childhood to adulthood may predict cardiometabolic risk in early adulthood. As part of the Southern California Children’s Health Study (CHS), we examined perceived stress score (PSS) in adolescence (mean age, 13.3 years) and young adulthood (mean age, 23.6 years) among 276 participants. Based on PSS in adolescence and young adulthood, participants were categorized into 4 stress pattern groups: consistently high (n = 85), decreasing (n = 49), increasing (n = 59), and consistently low (n = 65). CHS participants were assessed for seven measures of cardiometabolic disease risk, namely carotid artery intima-media thickness (CIMT), systolic and diastolic blood pressure (SBP and DBP), obesity, percent body fat, android/gynoid ratio, and elevated HbA1c in their young adulthood. An overall cardiometabolic risk score was generated by summing the number of clinically elevated measures to indicate cumulative cardiometabolic risk. Using multivariate linear and logistic regression models, we examined PSS measured at single time points and change in PSS score across adolescence to young adulthood in relation to cardiometabolic disease risk. Results indicated that PSS in adulthood had significant positive associations with overall cardiometabolic risk score (Beta, 0.12: 95% CI, 0.01-0.22; p =0.031), CIMT (Beta, 0.01; 95% CI, 0.00-0.02; p =0.043), SBP (Beta, 1.27, 95% CI, 0.09-2.45; p =0.035), and DBP (Beta, 0.94; 95% CI, 0.13-1.76; p =0.024). Further, analyses of PSS patterns suggested that individuals with consistently high PSS had higher cardiometabolic risk scores (Beta, 0.26; 95% CI, -0.02-0.54; p =0.066), as well as significantly higher android/gynoid ratio (Beta, 0.09; 95% CI, 0.03-0.14; p =0.002), percent body fat (Beta, 0.96; 95% CI, 0.51-5.41; p =0.018), and greater odds of obesity (OR, 5.73; 95% CI, 1.96-16.78; p = 0.001), compared to individuals with consistently low PSS. Our work suggests that perceived stress from adolescence to adulthood may contribute to cardiometabolic disease risk in adulthood. Interventions to reduce stress earlier in life (e.g., in adolescence) should be investigated for their potential to reduce cardiometabolic disease risk factors in young adulthood.
