Note, b = standardized coefficient. Bold font denotes statistically significant associations. Asterisks indicate statistically significant associations following false discovery rate correction. Model 1 adjusts for chronological age. biological sex, and self-identified race/ethnicity. Model 2 adjusts for Model 1 variables as well as educational attainment, body mats index category, smoking status, and alcohol use. The sample size for the other family status models is n = 3,710 (Model 1) and n = 3,635, (Model 2), for the other family support models is n = 3,370, and for the other family strain models is n = 3,569.
