“…We considered ten main outcomes of interest, which are already known to be influenced by GWG [5][6][7][8][9][10][11][12][13][14][15][16][20][21][22][23][24][25][26][27]: small for gestational age (SGA), large for gestational age (LGA), low birth weight (LBW) (<2,500 g), macrosomia (≥4,000 g), gestational hypertension, preeclampsia, caesarean delivery, operative virginal delivery, umbilical artery pH <7.0, and an Apgar Score at 5 min <7. SGA and LGA neonates were defined as birth weights below the 10th percentile and above 90th percentile, respectively, after matching for gestational age and sex.…”

Abstract. We aimed to determine the optimal gestational weight gain (GWG) in Japanese women with a Body Mass Index (BMI) ≥25 kg/m 2 . The present retrospective study investigated singleton pregnancies in 6,781 Japanese women registered in the Japan Society of Obstetrics and Gynecology system in 2013. We divided overweight and obese women into four GWG categories based on the Institute of Medicine (IOM) recommended: weight loss, small weight gain, within IOM criteria, and above IOM criteria. The adjusted odds ratios and predicted probabilities of maternal and neonatal outcomes of interest with weight change were calculated. In overweight women, GWG was associated with neonatal birth weight. In the loss and small gain subgroups, there was a significant increase in small for gestational age (SGA) and low birth weight neonates (LBW). Predicted probabilities showed the lowest risk was observed in a weight gain of 0 kg; the risk sharply increased at a gain of 11.5 kg. In obese women, weight gain increased the prevalence of large for gestational age (LGA) neonates; however; SGA was not associated with GWG. Predicted probabilities showed an increase in the risk with weight gain. The observed optimal GWG was 0 to 11.5 kg in overweight, and weight loss in obese, pregnant Japanese women. should gain between 5 and 9 kg to obtain the best maternal and perinatal outcomes [4]. However, a few studies from Europe and North America have suggested that a GWG below the IOM guidelines is associated with more favourable pregnancy outcomes in obese women [3,[7][8][9][10][11][12][13].Japanese women are more likely to be underweight than those in Europe and North America; therefore, the Submitted Jan. 22, 2018; Accepted Feb. 3, 2018 as EJ18-0027 Released online in J-STAGE as advance publication Mar. 20, 2018 Correspondence to: Shigeru Aoki, Perinatal Center for Maternity and Neonate, Yokohama City University Medical Center, 4-57 Urafunecyou, Minami-ku, Yokohama City, Kanagawa 232-0024, Japan. E-mail: smyyaoki@yahoo.co.jp obesity classification used in Japan differs from that developed by the IOM [14][15][16]. According to the criteria developed by the Japan Society of Obstetrics and Gynecology (JSOG), women with a BMI of ≥25 kg/m 2 are classified as obese without further subdivision [17]. Optimal weight gain for pregnant Japanese women with a BMI ≥25 kg/m 2 is assessed on a case-to-case basis [18,19]. In our previous study entitled, "Pregnancy outcomes based on pre-pregnancy body mass index in Japanese women: POBMIJ Study," we reported that the IOM classification is also applicable to pregnant Japanese women because overweight (25 kg/m 2 ≤ BMI <30 kg/m 2 ) and obese (BMI ≥30 kg/m 2 ) women have different pregnancy outcomes. In addition, when pregnancy outcomes were compared among three groups of pregnant Japanese women with GWG below, within, and above the IOMrecommended weight gain, pregnant women with GWG within the IOM criteria had the best pregnancy outcomes among those with a BMI <30 kg/m 2 , whereas no differences were observ...

“…But an expectant mother who herself had a high birth weight [83] and the body mass index of the expectant father were also found to be associated with excessive weight gain during pregnancy [72]. In addition, continued nicotine consumption [72,74], quitting smoking, and lack of physical activities [69,80,83] can also lead to excessive weight gain [83]. In contrast, regular physical activity during pregnancy can have a preventive effect on weight gain in pregnancy.…”

!In recent decades, the understanding of the short and longer term effects of health-damaging behaviors and mental health problems in pregnant women and the underlying mechanisms of these behaviors and illnesses has significantly increased. In contrast, little is known about the factors affecting individual pregnant women which contribute to health-damaging behaviors and mental illness. The aim of this paper was therefore to summarize the current state of research into the consequences of nicotine and alcohol consumption, malnutrition, excessive weight gain or obesity, and impaired mental health (depression and anxiety) during pregnancy. In addition, the characteristics of pregnant women which increase their risk of developing such behaviors or mental disorders are described. A better knowledge of these risks should make it easier for clinicians to identify cases at risk early on and put measures of support in place. A review of the literature has shown that certain characteristics of pregnant women (e.g. her relationship with her partner, a previous history of mental illness prior to pregnancy) are associated with various healthdamaging behaviors as well as with impaired mental health. Affected women often show an accumulated psychosocial stress which was already present prior to the pregnancy and which may persist even after the birth of the child.

“…They are also more likely to give birth by c-section (12)(13)(14)(15)(16). Obese women are at greater risk for medically induced preterm birth (2,17) and women who are obese prepregnancy are less likely to initiate breastfeeding and breastfeed for shorter durations (18).…”

A total of 7,496 births to 3,990 mothers from the National Longitudinal Survey of Youth 1979 survey are examined. Outcomes include macrosomia, gestational length, incidence of low birthweight, preterm birth, large and small for gestational age (LGA, SGA), c-section, infant doctor visits, mother's and infant's days in hospital post-partum, whether the mother breastfed, and duration of breastfeeding. Association of income outcomes with maternal pre-pregnancy obesity was examined using Ordinary Least Squares (OLS) regression to compare across mothers and fixed effects to compare within families. In fixed effect models we find no statistically significant association between most outcomes and prepregnancy obesity with the exception of LGA, SGA, low birth weight and preterm birth. We find that prepregnancy obesity is associated with a with lower risk of low birthweight, SGA, and preterm birth but controlling for prepregnancy obesity, increases in GWG lead to increased risk of LGA. Contrary to previous studies, which have found that maternal obesity increases the risk of c-section, macrosomia and LGA, while decreasing the probability of breastfeeding, our sibling comparison models reveal no such association. In fact, our results suggest a protective effect of obesity in that women who are obese prepregnancy have longer gestation lengths, and are less likely to give birth to a preterm or low birthweight infant.JEL Classification: I12, J13
