AbstractObjectivesThis study was aimed to analyze post-disaster birth outcomes in coastal and inland regions of Miyagi Prefecture, Japan.MethodsPrimary data sets were compiled from birth records of obstetric facilities and 12,808 patients were analyzed for baseline birth outcomes by region. Regional risk analysis of the low-birth-weight rate and premature birth rate were conducted using multi-level logistic regression analysis.ResultsFrom overall baseline birth outcomes, a preterm birth rate was 4.6% and low-birth-weight rate was 8.8%. Regional analysis revealed that a preterm birth rate was 3.2% (coastal) and 5.0% (inland), respectively, and the rate of low birth weight was 6.5% in the coastal and 8.5% in the inland region. In the risk analysis of low-birth-weight rate and preterm birth rate, the risk in the coastal region could not be considered any higher than in the inland region (adjusted odds ratio 0.91 [0.73-1.14] and 0.85 [0.46-1.59], respectively).ConclusionsThe incidence of preterm birth and low birth weight were not adversely affected by the disaster. Early transfer and intensive medical intervention may have led to those findings. Further survey will be necessary to determine the long-term effects in both mothers and children.SugawaraJ, IwamaN, HoshiaiT, TokunagaH, NishigoriH, MetokiH, OkamuraK, YaegashiN.

Background The prevalence of obesity in the population has increased in parallel with increasing rates of adverse pregnancy outcomes (APOs). Quantifying contemporary trends in prepregnancy obesity and associations with interrelated APOs (preterm birth, low birth weight, and pregnancy‐associated hypertension) together and individually can inform prevention strategies to optimize cardiometabolic health in women and offspring. Methods and Results We performed a serial, cross‐sectional study using National Center for Health Statistics birth certificate data including women aged 15 to 44 years with live singleton births between 2013 and 2018, stratified by race/ethnicity (non‐Hispanic White, non‐Hispanic Black, Hispanic, and non‐Hispanic Asian). We quantified the annual prevalence of prepregnancy obesity (body mass index ≥30.0 kg/m 2 ; body mass index ≥27.5 kg/m 2 if non‐Hispanic Asian). We then estimated adjusted associations using multivariable logistic regression (odds ratios and population attributable fractions) for obesity‐related APOs compared with normal body mass index (18.5–24.9 kg/m 2 ; 18.5–22.9 kg/m 2 if non‐Hispanic Asian). Among 20 139 891 women, the prevalence of prepregnancy obesity increased between 2013 and 2018: non‐Hispanic White (21.6%–24.8%), non‐Hispanic Black (32.5%–36.2%), Hispanic (26.0%–30.5%), and non‐Hispanic Asian (15.3%–18.6%) women ( P ‐trend < 0.001 for all). Adjusted odds ratios (95% CI) for APOs associated with obesity increased between 2013 and 2018, and by 2018, ranged from 1.27 (1.25–1.29) in non‐Hispanic Black to 1.94 (1.92–1.96) in non‐Hispanic White women. Obesity was most strongly associated with pregnancy‐associated hypertension and inconsistently associated with preterm birth and low birth weight. Population attributable fractions of obesity‐related APOs increased over the study period: non‐Hispanic White (10.6%–14.7%), non‐Hispanic Black (3.7%–6.9%), Hispanic (7.0%–10.4%), and non‐Hispanic Asian (7.4%–9.7%) women ( P ‐trend < 0.01 for all). Conclusions The prevalence of prepregnancy obesity and burden of obesity‐related APOs have increased, driven primarily by pregnancy‐associated hypertension, and vary across racial/ethnic subgroups.

BACKGROUND: Only one study has investigated the combined effect of maternal asthma and obesity on perinatal outcomes; however, it did not consider small-for-gestational age and large-for-gestational age infants.OBJECTIVES: To examine the impact of obesity on perinatal outcomes among asthmatic women.METHODS: A cohort of 1386 pregnancies from asthmatic women was reconstructed using three of Quebec’s administrative databases and a questionnaire. Women were categorized using their prepregnancy body mass index. Underweight, overweight and obese women were compared with normal weight women. The primary outcome was the birth of a small-for-gestational-age infant, defined as a birth weight below the 10th percentile for gestational age and sex. Secondary outcomes were large-for-gestational-age infants (birth weight >90th percentile for gestational age) and preterm birth (<37 weeks’ gestation). Logistic regression models were used to obtain the ORs of having small-for-gestational-age infants, large-for-gestational-age infants and preterm birth as a function of body mass index.RESULTS: The proportions of underweight, normal weight, overweight and obese women were 10.8%, 53.3%, 19.7% and 16.2%, respectively. Obese asthmatic women were not found to be significantly more at risk for giving birth to small-for-gestational-age infants (OR 0.6 [95% CI 0.4 to 1.1]), large-for-gestational-age infants (OR 1.2 [95% CI 0.7 to 2.2]) or having a preterm delivery (OR 0.7 [95% CI 0.4 to 1.3]) than normal-weight asthmatic women.CONCLUSIONS: No significant negative interaction between maternal asthma and obesity on adverse perinatal outcomes was observed.

Abstrak Latar belakang dan tujuan : Preeklampsia merupakan masalah komplikasi kehamilan yang menyumbang kematian ibu tertinggi di Jawa Timur. Preeklampsia dengan Indeks Massa Tubuh ibu obesitas akan meningkatkan perburukan luaran maternal dan perinatal. Penelitian ini bertujuan untuk menganalisis hubungan Indeks Massa Tubuh ibu preeklampsia dengan luaran maternal dan luaran perinatal. Metode: penelitian ini adalah analitik obsevasional dengan rancangan cross sectional, jumlah sampel 60 rekam medis ibu dan bayi baru lahir di Rumah Sakit Universitas Airlangga. Sampel terdiri dari ibu preeklampsia semua kategori IMT yaitu underweight, normal, overweight, obesitas grade I,II, dan III. Luaran perinatal yang diteliti adalah kematian perinatal, kelahiran prematur, IUGR (Intrauterine growth restriction), asfiksia, bayi berat lahir rendah,  Sindrom Respiratori Distres (SRD), sepsis, Necrotizing Enterocolitis (NEC) dan Intraventrikular Hemorrhage (IVH).

Preeclampsia with body mass index of obese mothers will increase the deterioration in maternal and perinatal outcomes. This study aims to analyze the body mass index of preeclampsia mothers with maternal and perinatal outcomes. Methods: This is an observational with cross-sectional design study, a sample of 60 pregnant women and newborn medical records at Universitas Airlangga Hospital. The sample consisted of preeclamptic women in all categories of body mass index such as underweight, normal, overweight, obesity grade I,II, and III. The perinatal outcomes observed are perinatal death, preterm birth, Intrauterine Growth Restriction (IUGR), asphyxia, low birth weight, Respiratory Distress Syndrome (RDS), sepsis, Necrotizing Enterocolitis (NEC), and Intraventricular Hemorrhage (IVH). Results: There is no significant association between body mass index of preeclampsia with perinatal outcomes. Which include preterm birth, Intrauterine Growth Restriction (IUGR), asphyxia, low birth weight and early complications Conclusion: there were no difference on maternal and perinatal outcomes in all categories Body mass index of preeclamptic women

The Relationship

Background and Aims: Cord blood leptin may reflect the leptinemic status of a newborn at birth more accurately than the leptin values of blood collected from other sites. The present study was undertaken to determine the relationship of cord serum leptin concentration at birth with neonatal and maternal anthropometric parameters. Materials and Methods: Blood was taken from the umbilical cord of the babies at delivery. Maternal anthropometric measurements were recorded at admission for delivery. Neonatal anthropometric measurements were recorded within 48 hours after delivery. Linear regression analysis was used to explore the relationship between cord serum leptin concentration and anthropometric parameters of the baby and the mother. Both Serum leptin and serum C-peptide levels were measured by chemiluminescence-based ELISA method. Results: The leptin concentration (ng/ml, mean±SD) in cord blood was 39.13±14.44. Cord leptin levels correlated with birth weight (r=0.673, p<0.0001), ponderal index (r=0.732, p<0.0001) but it did not correlate with maternal body mass index, gestational age (r=0.135, p=0.349) at delivery or cord serum C-peptide concentration (r=-0.049, p=0.735) or placental weight (r=0.203, p=0.157). Conclusion: There are associations between cord leptin concentration at delivery and birth weight, ponderal index (PI) of the babies but not body mass index (BMI) of the mothers. High leptin levels of the baby could represent an important feedback modulator of substrate supply and subsequently for adipose tissue status during late gestation.
