Mediation association of contextual risk and α-diversity measure microbiome richness by (a) diet quality, (b) Dietary Inflammatory Index (DII), (c) fiber intake, and (d) sex- and age-adjusted body mass index (BMI). The associations are adjusted for the other stress domains (life events, parental risk, interpersonal risk, direct victimization) and covariates (child sex, age, 5 genetic PCs, time in mail, season of production, batch, and number of reads). Results are pooled estimates from 30 imputed datasets.
