Gestational Weight Gain and Its Relationship with Maternal Characteristics

Both high and insufficient weight gain during pregnancy have been associated with adverse outcomes for mothers and their offspring.

To describe self-reported weight gain during pregnancy, assess the concurrence of this weight gain with issued recommendations, and investigate associations between lifestyle factors and weight gain.

In this cross-sectional study, 109 pregnant women hospitalized in one gynecological and obstetrics department completed questionnaires related to weight gain and lifestyle factors such as smoking, diet and exercise. Recommended weight gain was defined by the American Congress of Obstetricians and Gynecologists and was compatible with the Ministry of Health guidelines in Israel.

Fifty-three (49%) participants reported weight gain above the recommendation, 31 (28%) met the recommendations and 25 (23%) reported weight gain below the recommendations. Characteristics associated with high weight gain included past smoking and/or age above 36 years and/or body mass index (BMI) above 25 kg/m2. Only 34 women (31%) reported seeking professional nutritional counseling during pregnancy. An increased tendency to consult a nutritionist was reported among diabetic women.

Only a minority of women gained the recommended weight during pregnancy. High BMI and/or a history of smoking and/or older age were associated with weight gain above recommendations. Particular effort should be directed toward counseling women at high risk of weight gain during pregnancy.
