Table 1. Covariates retained through backward elimination in fully adjusted models.

Blood Cell Types	Covariates retained
White blood cell count (1000 cells/μL)	HEI-2015 score, illness past 30 days (flu, pneumonia, or ear infection), asthma, donated blood, poverty income ratio, BMI, smoking status, marital status
Red blood cell count (million cells/μL)	HEI-2015 score, asthma, anemia, blood transfusion, arthritis, cancer or malignancy, poverty income ratio, BMI, marital status, smoking status
Platelet count (1000 cells/μL)	HEI-2015 score, illness past 30 days (flu, pneumonia, or ear infection), donated blood, asthma, blood transfusion, arthritis, cancer or malignancy, BMI, marital status, smoking status, poverty income ratio

HEI = healthy eating index. BMI = Body Mass Index (weight(kg)/height(m2). All models adjusted for sex, age, race/ethnicity (non-Hispanic white, Mexican American, non-Hispanic black, other) and total sedentary time and MVPA, as appropriate.
