Design Of the 4030 participants in Phase 1 (1999), 3253 (81 %) participated in Phase 2 (2003) and 3058 (76 %) participated in Phase 3 (2006). Education was categorized as elementary, high school or college graduate. Study participants self-identified as White, Black or Pardo. BMI was calculated from measured weight and height. BMI trajectories were modelled using a generalized additive regression model with mixed effects (GAMM). Setting The Pro-Saúde Study, a longitudinal investigation of social determinants of health. Subjects Women (n 1441) and men (n 1127) who participated in the three phases of data collection and had complete information for all study variables. Results Women and men with less than ...

Purpose: John Henryism (JH) is a strong behavioral predisposition to engage in high-effort coping with difficult socioen­vironmental stressors. We investigated associations between JH and perceived general health (GH) among maintenance hemodialysis (MHD) patients in a multiracial Brazilian population.Design: The 12-item John Henryism Acting Coping (JHAC) Scale was completed by 525 patients enrolled in The Prospective Study of the Prognosis of Hemodialysis Patients (PROHEMO) in Salvador (Bahia) Brazil. JH scores could range from 12 to 60. The low and high JH groups were determined by a median split (<52 vs ≥52). The 36-Item Short Form Health Survey was used to determine GH score (range 0-100; higher means better health). Linear regression with extensive adjustments was used to test as­sociations.Results: Mean age was 48.3±13.7 years; 38.7% were female; 11.4% were White, 29.1% were Black and 59.4% were mixed race. JH was positively associated with higher GH in the whole sample (adjusted difference [AdjDif]=7.14, 95% CI= 2.98, 11.3) and similarly in men and women. A strong positive association between JH and GH was observed in non-Whites but not in Whites; (AdjDif in Blacks =16.4, 95% CI=8.37, 24.4). Also, a strong positive as­sociation between JH and GH was observed for patients aged <60 years (AdjDif =9.04, 95% CI = 4.46, 13.6) but not for older patients.Conclusions: The results indicate that MHD patients engaged in high-effort coping with socioenvironmental stressors as demonstrat­ed by high JH tend to feel more positively about their overall health. This seems to be especially the case for non-White and younger patients. Ethn Dis. 2018;28(4):539- 548; doi:10.18865/ed.28.4.539.
