Maternal preconceptional body weight, pregnancy weight gain and delivery outcome

Introduction: Maternal weight at the time of conception and gestational weight gain are the strongest predictors of infant birth weight. Obese women have a greater risk of hypertension, diabetes, complications during labour and delivery, postterm births, and late foetal death. Methods: 58 women, 21 to 39 years (average 29.2) were monitored during their pregnancy at the gynaecologists office. According to measured height and weight at the beginning of the pregnancy, their BMI was calculated. Weight gain was followed during pregnancy, and for infant’s data on birth weight and length, sex, and gestational age were collected. Results: BMI showed that 69.0% of women started their pregnancy as normal weight, 6.9% as underweight, and 24.1% as overweight. Weight gain during pregnancy (average duration of pregnancy was 39.5 gestational weeks), ranged from 2 to 23.1kg (average 13.4kg). Birth weight of infants was on average 3395.4g, and length 50.0cm. Overweight women gained less weight during pregnancy than the normal weighted (11.1kg vs 14.3kg ; p=0.026) and delivered babies with higher birth weight (3664.3g vs 3327.0g ; p=0.016). Women's BMI at the beginning of the pregnancy significantly negatively correlated with the gained weight and positively with the birth weight. Conclusions: The results affirmed that the overweight mothers deliver infants of higher birth weight what should be considered as the risk factor for obesity later in life.
