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 a...

BACKGROUND Pre-pregnancy weight and gestational weight gain (GWG) are important factors in both maternal and infant outcomes. Little information is available in relation to different levels of pre-pregnancy body mass index (BMI) and body weight gain on obstetric outcomes in Taiwan. This study investigated the associations between pregnancy complications with pre-pregnant BMI and GWG, in Taiwane...

BACKGROUND Weight gain is a long-recognized side-effect of antipsychotic (AP) drugs and a major health concern in the treatment of psychosis. The strength of the causal relationship between AP drug exposure and weight gain can only be gauged by a drugs trial conducted on AP-naive patients. METHOD We conducted a review of the literature regarding the amount of weight gain induced by APs in AP-...

this study was carried out to investigate the effect of esterification on the surface roughness of eastern cottonwood. eastern cottonwood was modified without using any catalyst and solvent at different temperatures and times with two linear chain carboxylic acid anhydrides (acetic anhydride or propionic anhydride). different weight percentage gains (wpgs) were obtained at different conditions....

maternal nutritional status and weight gain throughout pregnancy affect the outcome of pregnancy. the objective of this study was to determine prepregnancy body mass index and total weight gain during pregnancy in women from rural areas of guilan province, iran. prenatal and obstetrical records of 480 pregnant women who attended rural health centers between 2002 and 2003 including prepregnancy ...

Human clinical trials targeted at preventing gains in body weight using soy protein and isoflavones are limited to adults and yield conflicting results. We hypothesized that daily intake of soy protein/isoflavones would attenuate gains in body weight to a greater extent than a casein-based control in 18 to 19 year-old females. To test this hypothesis, we conducted a randomized, double blind, pl...

Effects of breed and sward surface height on ewe liveweight and body condition changes and on lamb liveweight gains during grazing in the spring and autumn were studied. The output per hectare in each season was also calculated. A total of 112 Gallega ewes (35Æ6 kg live weight) and 204 Latxa ewes (47Æ5 kg live weight) with their lambs were used during the spring (March–June) to study the effect...

The weights of single mealworms were continuously recorded at 20 degrees C during exposure to periods of constant humidity and to abrupt changes in atmospheric vapour pressure. Two exchange stages were recognized in each animal. Weight changes were either limited to slow losses, suggesting transpiration through the external cuticle, or showed more rapid humidity-dependent gains as well as losse...
