Goal‐Striving Stress and Incident Cardiovascular Disease in Blacks: The Jackson Heart Study. Issue 9 (5th May 2020) - Glover, LáShauntá M.
Abstract : Background: Goal‐striving stress (GSS), the stress from striving for goals, is associated with poor health. Less is known about its association with cardiovascular disease (CVD). Methods and Results: We used data from the JHS (Jackson Heart Study), a study of CVD among blacks (21–95 years old) from 2000 to 2015. Participants free of CVD at baseline (2000–2004) were included in this analysis (n=4648). GSS was examined in categories (low, moderate, high) and in SD units. Incident CVD was defined as fatal or nonfatal stroke, coronary heart disease (CHD), and/or heart failure. We used Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of incident CVD by levels of GSS, adjusting for demographics, socioeconomic status, health behaviors, risk factors, and perceived stress. The distribution of GSS categories was as follows: 40.77% low, 33.97% moderate, and 25.26% high. Over an average of 12 years, there were 140 incident stroke events, 164 CHD events, and 194 heart failure events. After full adjustment, high (versus low) GSS was associated with a lower risk of stroke (HR, 0.38; 95% CI, 0.17–0.83) and a higher risk of CHD (HR, 1.91; 95% CI, 1.10–3.33) among women. A 1‐standard deviation unit increase in GSS was associated with a 31% increased risk of CHD (HR, 1.31; 95% CI, 1.10–1.56) among women. Conclusions: Higher GSS may be a risk factor for developing CHD among women; however, it appears to be protective of stroke among women. These analyses should be replicated in other samples of black individuals.
