The sex ratio increased with each weight gain increase group from 0.96 in women gaining less than 11 lb to 1.14 in women gaining over 40 lb. Sex ratios were lowest in women delivering smaller infants 2500-2599 gm with a weight gain below 11 lb (sex ratio: 0.72) and were highest in women delivering infants over 4,499 gm and gaining over 30 lb (2.32) and over 40 lb (2.25).
Keywords: obesity, sex-related differences, gender-related differences, weight loss. 1. Introduction. Obesity is defined as excessive fat accumulation that can have a negative impact on health . Body mass index (BMI) is a commonly used parameter for obesity classification.
While women’s weight gain is in part due to biological pathways, through changes due to pregnancy, breastfeeding, postnatal retention of gestational weight gain (Mannan, Doi & Mamun, 2013), a primary finding of our analysis is that these gains are even greater for men, suggesting that the pathways underlying the connection between weight and number of children are not solely driven by the ...

This study was done to determine whether there is relationship in evidence by evaluating any association between maternal weight gain during pregnancy and the newborn sex ratio. 221: Impact of fetal gender on maternal weight gain during pregnancy - American Journal of Obstetrics & Gynecology
May 15, 2024 · Background The aim of this study was to evaluate commonly assumed causal relationships between body mass index (BMI), gestational weight gain (GWG), and adverse pregnancy outcomes, which have formed the basis of guidelines and interventions aimed at limiting GWG in women with overweight or obesity. We explored relationships between maternal BMI, total GWG (as a continuous variable and as ...

Apr 12, 2023 · We considered as common covariates (covariates used in all the analyses) 10 variables, based on Maitre et al. [].These covariates are cohort, year of birth, mother’s BMI, mother’s weight gain during pregnancy, gestational age, mother’s age during pregnancy, mother’s education, whether parents were native from the country cohort, parity, and children’s age at clinical assessment ...
