|概要||Low birth weight (LBW) is a major public health concern in Japan. From a public health perspective, it is necessary to identify the risk factors of LBW in the Japanese population and examine the association of pre-pregnancy BMI and gestational weight gain (GWG) with infant birth weight considering the maternal dietary intake.
In total, 250 singleton pregnancies were included. Dietary intake was assessed by a validated brief diet history questionnaire (BDHQ). The GWG were obtained by subtracting pre-pregnancy weight from the latest weight before delivery.
Pre-pregnancy BMI was positively associated with infant birth weight and 1-month body weight in the fully adjusted model. Pre-pregnancy BMI was also positively associated with infant birth weight in male infants, but not in female infants. However, pre-pregnancy BMI was positively associated with 1-month body weight in female infants, but not in female infants.
