“…Another study reported favourable gestational outcomes in obese women who gained less than 5 kg in weight over the course of pregnancy as compared to those who gained more than 5 kg (25). A large study on pregnant women in China followed over a 13 year period has also reported higher maternal and fetal adverse outcomes with excess gestational weight gain, as well as low birth weight following insufficient weight gain in pregnancy (26).…”

What is already known about the subjectMaternal obesity is a risk factor for adverse maternal and foetal perinatal outcomes.The Institute of Medicine gives recommendations for weight gain during pregnancy based on initial body mass index (BMI) category, but the effects of these weight changes on pregnancy outcomes has not been adequately described. What this study adds: This study supports an association between gestational weight gain and adverse outcomes in obese pregnant women. Older and primiparous women in the cohort had the highest rates of weight gain, while socioeconomic deprivation did not influence weight changes. Women were recruited into the study at their antenatal booking visit and had weights measured throughout pregnancy. Patterns of weight gain were described and related to maternal and neonatal outcomes.Main outcome measure: The primary outcome was a composite measure consisting of any of twelve adverse maternal and fetal outcomes. This was compared by categorised pregnancy weight gain (<0 kg, 0-5 kg, 5.1-9 kg and >9 kg). patterns of weight gain varied widely and missing data was common and non-random.There was a significant association between increased weight gain during pregnancy and poor maternal and fetal outcome.Conclusions: Weight gain in obese women during pregnancy can be highly variable. Our study supports an association between increased weight gain in pregnancy and adverse perinatal outcomes.

“…Low pre-pregnancy body mass index (BMI) is a significant risk factor for delivering low-birth weight (LBW) infants [1,2]. Gestational weight gain (GWG) and gestational week at delivery (GWD) are also crucial for preventing the delivery of LBW infants [1,2].…”

Background: The rate of low-birth weight infants in Japan has been increasing. Being underweight and increasing maternal age are risk factors for delivering low birthweight infants. Currently, pregnant Japanese women exhibit these risk factors for delivering low birthweight infants; however, little research has been conducted. This study aimed to investigate the associations between pregnancy characteristics in Japanese women and low birth weight infants. Methods: We enrolled 2551 pregnant women at >36 weeks of gestation and who delivered in metropolitan Tokyo. Pre-pregnancy body mass index was categorized using the World Health Organization classification. Gestational weight gain and birth weight were categorized based on the guidelines of the Ministry of Health, Labour and Welfare, Japan. The differences in pregnancy characteristics among three birth-weight categories,i.e., low birth weight, normal, and macrosomia, were assessed using the chisquare test. The risk ratios of low birth weight were estimated using logistic regression analysis. Results: In Japanese pregnancies, birth weight was associated with gestational week at delivery, gestational weight gain, pre-pregnancy body mass index, sex, parity, and maternal age (P<0.05). In particular, the risk of low birth weight increased with advanced maternal age (odds ratio=1.97), insufficient gestational week at delivery (odds ratio=9.00), low gestational weight gain (odds ratio=2.76), and female infant (odds ratio=2.06). Further, it decreased in multiparous women compared with that in primiparous women (odds ratio=0.57). Conclusions: These findings suggest that pregnant Japanese women who are ≥40 years old with a gestational weight gain of <7.0 kg, <37 gestational weeks at delivery, female baby, and primiparous should be checked carefully during the gestational period. In order to decrease the risk of low birth weight babies, women should be educated early about childbearing and pregnancy.

Abstract. Objective, to use prenatal health education and nutritional intervention strategies for pregnant women with pregnancy-related hypertension to explore the effect of interventions on patient outcomes and analyze them. Methods, a total of 90 pregnant women with gestational hypertension were selected and randomly divided into the observation group and the control group by random number method. The control group used the routine intervention nursing method. The observation group used prenatal health education and nutritional guidance. The values of blood pressure changes, delivery methods, weight changes, and other indicators were analyzed. Results Compared with the results of the control group, the normal rate of body weight gain during pregnancy in the observation group was significantly higher than that in the control group, and the difference between the groups was significant (P>0.05). In the observation group, the degree of satisfaction was significantly higher than that in the control group, with significant differences between groups. There was a statistically significant difference (P <0.05). The blood pressure of pregnant women in the observation group decreased significantly (P <0.05). Conclusion, The use of prenatal health education and nutritional intervention in patients with pregnancy-induced hypertension can help patients understand health knowledge, change their bad habits, and can help patients to improve clinical curative effect and improve the quality of life of patients. Maternal birth process progressed smoothly, effectively improving the outcome of childbirth, which is worth learning from in clinical practice.Pregnancy-induced hypertension is a common and unique disease that affects the life and health of pregnant women and perinatal babies. It is also a common complication during maternity gestation. The current stage is the second cause of death from maternal deaths in China. The main clinical manifestations include high blood pressure, proteinuria, and edema, severe symptoms such as headache, coma, convulsions, and even maternal and child deaths. Prenatal examination and treatment awareness are enhanced, and maternal mortality caused by pregnancy-induced hypertension is greatly reduced [1][2] . Therefore, if the prevention and treatment are not treated in time or the method selection is not appropriate, and a series of more serious complications are caused, the condition will progress to severe pre-eclampsia or even eclampsia, threatening the life safety of the mother and child. The importance of obstetricians should be emphasized on this issue, and the prevalence of pregnancies in pregnant women is currently on a sharp upward trend. The disease is more frequent in the second trimester of pregnancy. It is easy to restrict the growth and development of fetuses with pregnancy-induced hypertension, cause maternal dystocia, or cause more severe birth injury, and the mortality rate shows a significant upward trend. According to relevant investigation reports, the main cause of the disea...

Abstract: Being overweight/obese and having a high weight gain, as well as being underweight and having a low weight gain, were associated with increased risks for adverse pregnancy outcomes in Chinese women.
