- Abstract: Determining the predictors of serum retinol at mid-pregnancy is relevant for planning interventions aimed at improving vitamin A status ofpregnant women and their offspring. This prospective study assessed predictors of serum retinol at the beginning of the third trimester ofpregnancy. We enrolled 442 pregnant women living in the urban area of Cruzeiro do Sul, Western Brazilian Amazon. Demographic, socio-economic, environmental and clinical characteristics as well as obstetric history, anthropometric, dietary and biochemical data, includingserum retinol, were gathered between 16 and 20 gestational weeks. Serum retinol also measured at the beginning of the third trimester ofpregnancy (approximately 28 gestational weeks) was the outcome of interest. Multiple linear regression models were used to evaluateassociations with the outcome. Overall, the following variables explained serum retinol at the beginning of the third trimester of pregnancy inthe adjusted model (R2=11·1 %): seasonality (winter season–November to April;β=0·134; 95 % CI 0·063, 0·206), weekly consumption ofAmazonian fruits (β=0·087; 95 % CI 0·012, 0·162) and retinol concentrations between 16 and 20 gestational weeks (β=0·045; 95 % CI 0·016,0·074) were positively associated, whereas having a smoker in the house was negatively associated (β=–0·087; 95 % CI:–0·166,–0·009).Consumption of pro-vitamin A-rich fruits by pregnant women should be encouraged. Passive smoking may play a role in decreasing vitamin Astatus as a proxy of smoking exposure during pregnancy
