“…According to a prospective cohort study in the USA, GWG within the levels recommended by the Institute of Medicine (IOM) guidelines was associated with a decreased risk of delivering LBW babies [1]. In Mexico, adequate GWG decreases maternal and infant adverse outcomes [24]. In this study, the proportion of LBW in both underweight and average pregnancies based on MHLW weight gain guidelines was higher.…”

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.

“…Whiteman et al [22] found in women with increasing BMI in 2 subsequent pregnancies an elevated stillbirth risk with a hazard ratio between 1.2 and 1.5 depending on BMI before the first pregnancy and weight gain between the 2 consecutive pregnancies. Reyes et al [23] showed that intense nutritional control in early pregnancy reduces the risk for perinatal adverse outcomes. Thus, obesity is an important risk factor for perinatal mortality, the impact of which can be diminished by control of maternal weight.…”

Objective: To investigate the impact of advanced maternal age on the rate of perinatal mortality. Design: Retrospective cohort study including all 56,517 singleton hospital deliveries between 1999 and 2008. Methods: Data were analyzed according to maternal age at delivery in 3 groups of women, 25-34 years, 35-39 years and ≥40 years, using the youngest as the reference group. Results: Odds ratios (ORs) for antenatal deaths were 0.98 (CI: 0.67-1.43) and 2.57 (CI: 1.57-4.22) for age groups 35-39 years and ≥40 years, respectively. Significant differences in neonatal mortality rates between the age groups were not found. Significant amendable risk factors were attendance of <4 health care visits (OR = 15.55, CI: 9.47-25.51 in age group 35-39 years; OR = 16.38, CI: 9.78-27.43 in the age group ≥40 years) and obesity (OR = 1.85, CI: 1.27-2.70 in age group 35-39 years; OR = 1.83, CI: 1.22-2.74 in the age group ≥40 years). In the multivariate regression analysis, the adjusted ORs for perinatal mortality were 1.03 (95% CI: 0.77-1.39) and 1.66 (95% CI: 1.03-2.66) for age groups 35-39 and ≥40, respectively. Conclusions: Women older than 40 years carry an increased risk for stillbirth. Important amendable risk factors are obesity and poor antenatal care.

“…For example, in a recent study of women seeking prenatal care for singleton pregnancies at the National Institute of Perinatology in Mexico during 2007–2008, 17% of normal‐weight women gained above the recommended amount of weight compared to 35.7% of overweight women and 22.4% of obese women. The odds of poor maternal outcomes including gestational diabetes mellitus, preeclampsia, and lack of spontaneous initiation of labor were greatest for obese women in the sample …”

The impact of the obesity epidemic on women of childbearing age has been of particular concern in recent years as a result of studies linking maternal weight status to long-term adverse outcomes for obese mothers and their offspring. The US Institute of Medicine developed new gestational weight gain guidelines based on this literature that attempts to strike a balance between the known risks and benefits of weight gain during pregnancy. More studies that include large numbers of obese women, examine outcomes beyond the perinatal period, and identify safe and effective pregnancy weight gain interventions are needed before lower weight gain recommendations can be made for obese women.
