AIM Women diagnosed with abnormal glucose tolerance and gestational diabetes mellitus are at increased risk for subsequent type 2 diabetes, with higher risks in Hispanic women. Studies suggest that physical activity may be associated with a reduced risk of these disorders; however, studies in Hispanic women are sparse. METHODS We prospectively evaluated this association among 1241 Hispanic pa...

KEY POINTS Sleep disordered breathing (SDB) is common and the severity increases as pregnancy progresses.Frequent snoring, older age and high pre-pregnancy body mass index (>25 kg⋅m(-2)) could be reliable indicators for SDB in early pregnancy.SDB screening tools, including questionnaires, used in the nonpregnant population have poor predictive ability in pregnancy.Accumulating evidence suggests...

Background: The timing of maternal weight change in pregnancy may be an important determinant of birth weight. The objective of this study was to measure weight gain patterns from early pregnancy until delivery, and to examine the relationship between prenatal weight gain and low birth weight. Methods: A total of 500 pregnant women within 15-20 days of conception, with confirmed pregnancies and...

The aims of this study were to compare the effects of Swedish snuff and cigarette smoking on preeclampsia risk and to estimate whether changes in tobacco habits during pregnancy affect the risk of devel...

It is well established that the death of one fetus in a monochorionic twin pregnancy places the surviving twin at significant risk for neuro-developmental delay or death. Although the early 1st trimester "vanishing twin" has not traditionally been considered a major risk, the precise gestational threshold beyond which a surviving twin is at risk remains uncertain. Most experts recommend serial ...

BACKGROUND Despite being associated with lower birth weight, maternal smoking in the last 2 trimesters of pregnancy has been associated with increased risk of offspring overweight in several studies. To date, only one study has examined whether smoking in the first trimester only, which is not associated with birth weight, is also associated with childhood overweight. OBJECTIVE This study use...
