OBJECTIVE To evaluate the incremental effect of weight gain above that recommended for term pregnancy (15 pounds) on postpartum weight retention at 1 year among obese women. METHODS In a retrospective cohort study, we identified 1,656 singleton gestations resulting in live births among obese women (body mass index at or above 30 kg/m) between January 2000 and December 2005 in Kaiser Permanent...

BACKGROUND Pregnancy is characterised by large weight gain over a short period, and often a notable change in mode of transportation. This makes pregnancy suitable for examining the plausible, but in the scientific literature still unclear, association between active transportation and weight gain. We hypothesize that women continuing an active mode of transportation to work or school from pre-...

OBJECTIVE To examine pregnant women's weight-related attitudes and behaviors in relation to a constellation of psychosocial characteristics, prepregnancy body habitus, and gestational weight gain. PARTICIPANTS One hundred-thirty women with low-risk, normal pregnancies. DESIGN Cross-sectional, observational study assessed attitudes about weight gain at 36 weeks' gestation.

BACKGROUND Body mass index (BMI) before pregnancy and weight gaining during pregnancy affect infant birth weight and are associated with unfavorable pregnancy outcomes. The aim of this study was to describe the weight gain pattern of Iranian pregnant women according to the BMI status at the beginning of pregnancy. METHODS This was a longitudinal cross sectional study. A total of 500 pregnant ...

The aim of the present experiment was to determine the relationship between placental and fetal weight after placental growth had been retarded by maternal undernutrition. Placental weight and fetal weight were measured in single-lamb-bearing ewes which were well-fed throughout pregnancy, or severely undernourished between the 30th and 96th day of pregnancy. Placental transfer of calcium and wh...

BACKGROUND The relationship between maternal hemoglobin (Hb) levels during pregnancy and birth outcomes has been controversial. Changes in Hb level during pregnancy may have an impact on birth outcomes. This study aimed to investigate whether changes in Hb levels from early to mid- or late pregnancy is associated with birth outcomes. METHODS Participants were singleton mothers who delivered a...

PURPOSE To evaluate weight retention 12 months postpartum and factors associated among women who had received prenatal care at Health Care Centers in Porto Alegre, southern Brazil. METHODS Pregnant women in the last trimester were identified at 20 Health Care Centers. Socioeconomic, demographic and anthropometrics data were obtained. Six and 12 months after delivery, the women received home v...

BACKGROUND To establish the unbiased relation between maternal weight gain in pregnancy and perinatal health, a classification for maternal weight gain is needed that is uncorrelated with gestational age. OBJECTIVE The goal of this study was to create a weight-gain-for-gestational-age percentile and z score chart to describe the mean, SD, and selected percentiles of maternal weight gain throu...
