Objective:
BMI is commonly used to measure risk to prenatal health but may not be sensitive to adiposity-associated health problems for Black women. The aim of the present study was to test associations between indices of prenatal health and BMI in Black women.
Methods:
Data were from 652 women enrolled in two studies. Height and weight were used to calculate BMI. Depression and perceived stress were measured via maternal report, systemic inflammation via C-reactive protein (CRP), and nutrition by the ratio of omega-3 docosahexaenoic acid to omega-6 arachidonic acid fatty acids.
Results:
Neither perceived stress, depression, nor fatty acids were associated with prenatal BMI. CRP levels were positively associated with BMI (beta = 6.56, t = 13.30, p < .001). The prevalence of high-risk levels of CRP (> 3 mg/L) was below 10% for all weight classes except for BMI ≥ 40.
Conclusions:
Results suggest that BMI may not be a sensitive index of adiposity related risk to prenatal health for Black women.
