Abstract:

Introduction: Birth weight, as one of the main indices of growth, is among the determining factors of survival. Given the absence of documented studies and lack of information regarding the influence of mothers’ body mass index (BMI) on newborns’ birth weight, this study was carried out with the aim to determine the relation between the mother’s BMI at the beginning of pregnancy and the infant’s weight at birth. Methods: In the current cross-sectional study, 800 pregnant women, who were referred to medical and healthcare centers of Mashhad during 2011 (with a gestational age less than 12 weeks), were selected using stratified random multi-level cluster sampling. In the first prenatal checkup, a questionnaire, containing questions about personal information, was completed and mothers’ BMIs were calculated. At birth, the infants’ weight and other variables were surveyed. Analysis of data was done using SPSS version 11.5 and descriptive and analytical tests. Results:Among 800 mothers, 14% were underweight (BMI
