Aims/Introduction: To prospectively investigate whether simultaneous elevation of gamma‐glutamyl transferase (GGT) and alanine aminotransferase (ALT) is associated with the increase of type 2 diabetes mellitus incidence independent of alcohol drinking, body mass index and triglycerides.Methods: A total of 2,775 Japanese male workers who had no history of type 2 diabetes mellitus were followed. High GGT and ALT were defined as the top tertiles (GGT cutpoint: 49 IU/L, ALT cutpoint: 28 IU/L). Three groups were created using these dichotomized GGT and ALT cutpoints: both low, either high or both high. Multivariable Cox proportional hazards models were carried out adjusted for potential confounding factors.Results: A total of 276 type 2 diabetes mellitus cases were identified during 12 years (27,040 person‐years) of follow up. Participants with simultaneously elevated GGT and ALT had a significantly higher incidence of type 2 diabetes mellitus, even after adjustment for fasting insulin and fasting blood glucose compared with the group without GGT or ALT elevation. Similar associations were observed in non‐ or light‐to‐moderate alcohol drinkers, as well as in participants with normal weight. However, the association was weaker in participants with triglycerides <150 mg/dL. We then evaluated whether the addition of GGT and ALT would improve the prediction of type 2 diabetes mellitus incidence, and found that their inclusion significantly increased the C‐statistic, net reclassification improvement and integrated discrimination improvement.Conclusions: Simultaneous elevation of GGT and ALT was significantly associated with type 2 diabetes mellitus incidence, independent of potential confounding factors, including alcohol drinking and obesity, although the association might require concomitant elevation of triglycerides. Inclusion of GGT and ALT improved type 2 diabetes mellitus risk prediction.

Context Maternal cholesterol is important for fetal development. Whether maternal serum total cholesterol (maternal TC) levels in midpregnancy are associated with small (SGA) or large (LGA) for gestational age independent of prepregnancy body mass index (BMI) and weight gain during pregnancy is inconclusive. Objective This work aimed to prospectively investigate the association between maternal TC in midpregnancy and SGA or LGA. Methods The Japan Environment and Children’s Study is a nationwide prospective birth cohort study in Japan. Participants in this study included 37 449 nondiabetic, nonhypertensive mothers with singleton birth at term without congenital abnormalities. Birth weight for gestational age less than the 10th percentile and greater than or equal to the 90th percentile were respectively defined as SGA and LGA by the Japanese neonatal anthropometric charts. Results The mean gestational age at blood sampling was 22.7 ± 4.0 weeks. After adjustment for maternal age, sex of child, parity, weight gain during pregnancy, prepregnancy BMI, smoking, alcohol drinking, blood glucose levels, household income, and study areas, 1-SD decrement of maternal TC was linearly associated with SGA (odds ratio [OR]: 1.20; 95% CI, 1.15-1.25). In contrast, 1-SD increment of maternal TC was linearly associated with LGA (OR: 1.13; 95% CI, 1.09-1.16). Associations did not differ according to prepregnancy BMI and gestational weight gain (P for interaction > .20). Conclusion Maternal TC levels in midpregnancy were associated with SGA or LGA in a Japanese cohort. It may help to predict SGA and LGA. Favorable maternal lipid profiles for fetal development must be explored.

Background: In Burundi, birth certificate ownership (56.4%) and postnatal care (PNC) coverage (30%) remain low. Birth certificates prove birth registration and allow clients to receive free medical care including PNC. To obtain birth certificates, notification of birth by witnesses is indispensable. However, use of existing parallel home-based records for mother and child has prevented clients from successfully receiving notification of birth and related information. Objective: To assess the effectiveness of the Maternal and Child Health (MCH) handbook for increasing notification of birth at health facilities and PNC uptake. Methods: Pre- and post-introduction measurement were applied including: (i) structured interviews with two different sets of randomly selected mothers having infants aged less than six weeks at the pre- or post-studies; and (ii) secondary data from the national health management information system. Results: 95.1% of mothers had an MCH handbook post-study. Significant improvement was observed in the proportion of mothers receiving notification of birth at health facilities, from 4.6% to 61.0% (95% confidence interval [CI]: 55.9%–66.2%), and the proportion of mothers receiving guidance on PNC, from 35.9% to 64.2% (95% CI: 59.2%–69.3%). The annual PNC coverage (43.9% to 54.2%; p < 0.05) in the Gitega District significantly increased from 2013 to 2014. Among MCH handbook owners, mothers giving birth at hospitals/clinics had 2.62 higher odds (95% CI: 1.63–4.22) of obtaining notification of birth than mothers giving birth at health centers. Conversely, mothers delivering at hospitals/clinics had 0.51 lower odds (95% CI: 1.63–4.22) of receiving PNC guidance than mothers delivering at health centers. Conclusions: As previous studies showed, the MCH handbook appeared to help health personnel provide guidance on PNC, thereby it may have increased PNC. Furthermore, this study suggests the handbook contributed to every birth being counted. However, to increase the effectiveness of the handbook, health personnel should be encouraged toward its proper use.

Aims/Introduction: The Japanese government started a nationwide screening program for metabolic syndrome (MetS) to prevent cardiovascular diseases and diabetes in 2008. Although impaired fasting glucose (IFG) is a strong predictor for type 2 diabetes mellitus, the program does not follow up IFG in non‐MetS individuals. This study aimed to examine the risk and the population attributable fraction (PAF) of MetS and IFG for incidence of type 2 diabetes mellitus.Materials and Methods: Japanese workers (3,417 men and 714 women) aged 40–64 years without a history of diabetes were prospectively followed. MetS was defined as either abdominal obesity plus two or more metabolic risk factors, or being overweight in the case of normal waist circumference plus three or more metabolic risk factors. IFG was defined as fasting blood glucose 100–125 mg/dL.Results: During a mean 6.3 years, 240 type 2 diabetes mellitus cases were identified. Compared with those without MetS and IFG, the multivariable‐adjusted hazard ratios (95% confidence interval) of non‐MetS individuals with IFG, MetS individuals without IFG and MetS individuals with IFG for type 2 diabetes mellitus were 4.9 (3.4–7.1), 2.4 (1.6–3.5) and 8.3 (5.9–11.5), respectively. The corresponding PAFs for type 2 diabetes mellitus incidence were 15.6, 9.1 and 29.7%, respectively.Conclusions: IFG represented a higher risk and PAF than MetS for type 2 diabetes mellitus incidence in middle‐aged Japanese individuals. The coexistence of MetS and IFG showed the highest risk and PAF for type 2 diabetes mellitus incidence. The current Japanese MetS screening program should be reconsidered to follow up non‐MetS individuals with IFG.

There are a limited number of studies in which the depression status was followed up throughout pregnancy and postpartum to 1 year after delivery though 8.6-33% of women with recurrent pregnancy loss (RPL) and 10-25% of women who undergo in vitro fertilization and embryo transfer (IVF-ET) suffer from depression. We examined whether RPL and IVF-ET affect depressive symptoms during pregnancy and postpartum. A nationwide large-scale birth cohort study known as the "Japan Environment and Children's Study (JECS)" was conducted. The subjects consisted of 99,202 pregnant women recruited between January 2011 and March 2014. The Kessler Psychological Distress Scale was used for the 1st trimester, 2nd/3rd trimester and 1 year postpartum. The Edinburgh Postnatal Depression Scale was used for the first and the sixth month postpartum. The screening instruments were used to quantify depressive symptoms. Women with no live births had a significantly higher prevalence of elevated depressive symptoms throughout pregnancy and postpartum. The prevalence of elevated depressive symptoms was significantly higher in the second/third trimester among women with three or more pregnancy losses with no live births. IVF-ET was associated with reduced risk of developing depressive symptoms during all pregnancies and at 1 and 6 months after delivery in women with no live births. RPL and IVF-ET did not affect postpartum depressive symptoms, and IVF-ET rather reduced the risk of depression throughout pregnancy and postpartum. Psychological support for RPL women would be necessary.
