Objective: To investigate birth-to-childhood tracking of linear growth and weight gain across the distribution of length/height and weight for age z-scores and according to household wealth.
Methods: Data from 614 children from the MINA-Brazil Study with repeated anthropometric measurements at birth and up to age five years were used. Z-scores were calculated for length/height (HAZ) and weight (WAZ) according to international standards.
Objectives: To determine predictors of 25-hydroxyvitamin D (25(OH)D) concentrations (25, 50, and 75 percentiles) in the third trimester of pregnancy.
Subjects/methods: Data on sociodemographic, obstetric, lifestyle and pregnancy characteristics, including serum 25(OH)D and retinol, were collected among 448 pregnant women who participated in the Maternal and Child Health and Nutrition in Acre, Brazil (MINA-Brazil Study) in Cruzeiro do Sul, Brazilian Amazon (latitude 7°S). Simultaneous-quantile regression was fitted to prospectively assess predictors at the 25, 50 and 75 percentiles of 25(OH)D concentrations.
