The effect of maternal obesity gestational weight gain breast-feeding. It has been recognized that it might be problematic to link total gestational weight gain with pregnancy outcomes that are highly correlated with gestational age at birth, such as preterm birth. In addition, numerous studies have shown a lower sum of Apgar scale in infants of obese mothers, while our study did not show that there are statistically significant differences in the vitality of newborns according to body mass index of mothers at the beginning and the end of their pregnancies or depending on weight gain of mothers during pregnancy, one of the possible reasons being the small sample size Table 4 920 Based on a recent systematic review of 12 studies involving 2, women from 9 countries, differences in the methodological quality of gestational weight gain studies may explain the varying chart recommendations. Despite the range of cultures, behaviors, clinical practices, and traditions, which can strongly influence gestational weight gain, we did not observe differences in the patterns of weight gain between cohorts and countries. The physician-side survey was completed by physicians and epidemiologists and included three surveys about information on prenatal examination, maternal delivery outcomes and infant outcomes.

Population-based assessment of the risk of primary cesarean delivery due to excess Prepregnancy weight among nulliparous women delivering term infants. In addition, data from the Pregnancy Risk Assessment Monitoring System PRAMS were analyzed to estimate prevalence for five states with available data that had not yet adopted the birth certificate. Conclusion: The gestational weight gain limits for BMI categories determined in this large population-based cohort study from Swedish Medical Registers showed that a decreased risk of adverse obstetric and neonatal outcomes was associated with lower gestational weight gain limits than was earlier recommended, especially among obese women. Excessive gestational weight gain predicts large for gestational age neonates independent of maternal body mass index.

Bmi mass index in the early stages of pregnancy BMI 1 and body mass index of pregnant women at the end of their pregnancy BMI 2 proved to be a significant element in the development of complications during pregnancy; the highest amount of complications during pregnancy occurred in the group of obese pregnant women. Also, due to the data request format within this collaboration, only one weight measurement at early, mid, and late pregnancy was obtained, when available, for each woman even if multiple weight measurements were taken during each period. Strengths and limitations Strengths of this study were the description of the pattern of weight gain throughout pregnancy in a large sample of pregnant women from 33 cohorts from Europe, North America, and Oceania.
