Gestational hypertension is associated with increased risk of type 2 diabetes in adult offspring: the Helsinki Birth Cohort Study.

ABSTRACT: Women with hypertensive disorders in pregnancy are at an increased risk of cardiovascular disease and type 2 diabetes later in life. Offspring born from these hypertensive pregnancies have increased levels of cardiovascular risk factors; whether they are at an increased risk of type 2 diabetes is not known.The objective of the investigation was to study the risk of type 2 diabetes in the adult offspring exposed to maternal preeclampsia or gestational hypertension in utero.We studied 5335 members of the Helsinki Birth Cohort Study, who were born between 1934 and 1944 and who lived in Finland in 1995 when the National Medication Purchase Register was initiated. We ascertained gestational hypertension and preeclampsia according to modern criteria by using maternal and birth records. We defined type 2 diabetes through purchases of antidiabetic medication recorded in the comprehensive National Medication Purchase Register, excluding the 31 subjects who had purchased only insulin. We used Cox regression to assess hazard ratios for type 2 diabetes.A total of 590 men (21.6%) and 433 women (16.9%) had purchased medication for diabetes. The hazard ratio for type 2 diabetes for offspring exposed to any maternal hypertension in pregnancy was 1.13 (95% confidence interval, 1.00-1.29; n = 1780). For maternal gestational hypertension, it was 1.15 (95% confidence interval, 1.00-1.33; n = 1336) and for preeclampsia 0.98 (95% confidence interval, 0.71-1.34; n = 231). For type 2 diabetes with first medication purchase before 62 years, the corresponding hazard ratios were 1.25 (95% confidence interval, 1.04-1.51); 1.28 (95% confidence interval, 1.05-1.58), and 1.18 (95% confidence interval, 0.75-1.84). The hazard ratios were similar when adjusted for birthweight SD score for gestation, length of gestation, maternal body mass index in late pregnancy, height, age, and parity and for childhood or adult socioeconomic position. An increased risk of type 2 diabetes was also associated with low birthweight SD score, independent of the association with gestational hypertension.Offspring exposed to maternal gestational hypertension in utero have an increased risk of type 2 diabetes in late adult life. This finding underlines the role of the whole spectrum of hypertensive disorders of pregnancy as risk factors of offspring disease throughout life. It also reinforces previous suggestions that adult health care providers should incorporate birth histories when evaluating an individual's risk to develop type 2 diabetes.

Project description:ObjectiveGestational diabetes mellitus (GDM) affects a significant number of women. Evidence regarding the association between GDM and offspring body mass index (BMI) is unclear due to small samples and lack of adequate confounding control. The objective of this study was to investigate the association between GDM and offspring BMI z-scores from birth to early adolescence and to examine the role of maternal pre-gestational BMI in this relationship.DesignProspective study.SettingPelotas 2004 Birth Cohort, Brazil.ParticipantsCohort participants that were followed-up from birth up to early adolescence (~3500) and their mothers.Primary outcome measuresBMI z-scores at birth, 3, 12, 24, 48 months and 6 and 11 years of age, calculated according to the WHO growth charts.ResultsUnadjusted and adjusted linear regressions were performed and interaction terms between maternal pre-gestational BMI and GDM were included. Prevalence of self-reported GDM was 2.6% (95% CI 2.1% to 3.1%). The offspring BMI z-scores (SD) at birth, 3, 12, 24, 48 months and at 6 and 11 years were 0.10 (1.12), -0.47 (1.10), 0.59 (1.10), 0.59 (1.08), 0.78 (1.32), 0.70 (1.43) and 0.75 (1.41), respectively. Unadjusted regression models showed positive associations between GDM and offspring BMI z-scores at birth, 6 and 11 years. After adjustment, the associations attenuated towards the null. Statistical evidence of effect modification between maternal pre-gestational BMI and GDM was observed at birth (p=0.007), with the association between GDM and offspring BMI z-score being apparent only in those children born to overweight or obese mothers (?=0.72, 95%?CI 0.30 to 1.14 and ?=0.61, 95%?CI 0.20 to 1.01, respectively).ConclusionsWe observed that in the association between GDM and offspring BMI z-scores, there is a predominant role for maternal nutritional status before pregnancy and that the association between GDM and newborn's BMI is apparent only among those born to overweight or obese mothers.

Project description:BACKGROUND:Gestational diabetes mellitus (GDM) is associated with increased availability of glucose and macronutrients in fetal circulation and macrosomia. Therefore, the role of GDM in the association between metabolism-disrupting chemicals and birth size deserves attention. OBJECTIVE:We examined whether GDM may mediate or modify the associations between maternal environmental pollutant exposures and offspring birth size measures. METHODS:We analyzed 604 Faroese pregnant women and their offsprings born in 1997-2000. Maternal pregnancy serum concentrations of organochlorine compounds (OCs: polychlorinated biphenyl (PCB) congeners and dichlorodiphenyldichloroethylene (DDE)), and five perfluoroalkyl substances (PFASs), and hair and cord blood mercury concentrations were measured. We used regression (single-pollutants) and structural equation models (SEMs) (multiple-pollutant analyses using latent constructs of OCs, PFASs and mercury) to estimate the associations with GDM and birth size measures, accounting for mediation and/or effect modification by GDM. RESULTS:Serum-DDE and hair-mercury concentrations were associated with GDM (adjusted OR per concentration doubling: 1.29; 95% CI: 0.94, 1.77 for DDE, and 0.79; 95% CI: 0.62, 0.99 for mercury), but in multiple pollutant-adjusted SEMs only a positive association between OC exposure and GDM remained significant (change in GDM odds per OC doubling: 0.45; 95% CI: 0.05, 0.86). PCB and overall OC exposure were positively associated with head circumference (SEM; mean change per OC doubling: 0.13cm; 95% CI, 0.01. 0.25). Overall PFAS exposure was inversely associated with birth weight (SEM; mean change per PFAS doubling: -169g; 95% CI: -359, 21), and for many single-PFASs we found a pattern of inverse associations with birth weight and head circumference in boys, and positive or null associations in girls. None of the environmental pollutants was associated with offspring length. GDM neither modified nor mediated the associations with birth size measures. CONCLUSIONS:We found associations with GDM and offspring birth size to be specific to the environmental pollutant or pollutant group. Associations with birth size measures appear to be independent of GDM occurrence.
