Item Mid-pregnancy sleep disturbances are not associated with mid-pregnancy maternal glycemia(medRxiv, 2023-04-26) Hawkins, Marquis; Feghali, Maisa; Abebe, Kaleab Z.; Scrifres, Christina M.; Lalama, Christina M.; Costacou, Tina; Catalano, Patrick; Simhan, Hyagriv; Orris, Steve; Mendez, Dara; Buysse, Daniel J.; Davis, Esa M.; Obstetrics and Gynecology, School of MedicineBackground: In pregnancy, epidemiological data have consistently shown strong associations between sleep quality and duration and maternal glycemia. However, other sleep disturbances such as difficulty falling asleep and staying asleep are common in pregnancy. They may contribute to impaired maternal glycemia through sympathetic nervous system activity, systemic inflammation, and hormonal pathways. However, there is little research examining associations between these specific sleep disturbances and maternal glycemia. Objective: This study aimed to investigate the associations of sleep disturbances during mid-pregnancy and mid-pregnancy maternal glycemia and gestational diabetes subtypes. Study design: This is a secondary data analysis of the Comparison of Two Screening Strategies for Gestational Diabetes trial. Participants (n = 828) self-reported the frequency of sleep disturbances (i.e., trouble falling asleep, trouble staying asleep, waking several times per night, and waking feeling tired or worn out) in mid-pregnancy. Gestational diabetes was diagnosed using either the International Associations of Diabetes and Pregnancy Study Groups or Carpenter-Coustan approach. We defined gestational diabetes subtypes based on the degree of insulin resistance and beta-cell dysfunction. We used multinomial logistic regression to examine associations of sleep disturbances with gestational diabetes status (i.e., normal, mild glycemic dysfunction, and gestational diabetes) and gestational diabetes subtypes (i.e., neither insulin resistance or beta-cell dysfunction, insulin resistance only, beta-cell dysfunction only, and insulin resistance and beta-cell dysfunction). Results: A total of 665 participants (80%) had normal glycemia, 81 (10%) mild hyperglycemia, and 80 (10%) had gestational diabetes. Among participants with gestational diabetes, 62 (78%) had both insulin resistance and beta-cell dysfunction, 15 (19 %) had insulin resistance only, and 3 had beta-cell dysfunction only or neither insulin resistance nor beta-cell dysfunction. Sleep disturbance frequency was not associated with maternal glycemia or gestational diabetes subtypes. Conclusions: Sleep disturbances in mid-pregnancy were not associated with maternal glycemia during mid-pregnancy. Future research should collect data on sleep disturbances at multiple time points in pregnancy and in combination with other sleep disturbances to determine whether sleep plays any role in maternal glycemic control.Item Treatment of Gestational Diabetes Mellitus and Offspring Early Childhood Growth(Endocrine Society, 2021-04) Feghali, Maisa; Atlass, Jacqueline; Abebe, Kaleab Z.; Comer, Diane; Catov, Janet; Caritis, Steve; Arslanian, Silva; Scifres, Christina; Obstetrics and Gynecology, School of MedicineBackground: Gestational diabetes mellitus (GDM) is associated with fetal overgrowth, and certain treatments are associated with an increased risk of macrosomia. However, there are limited data about the long-term effect of GDM treatment on childhood growth. Methods: Cohort study of 816 women with GDM and their offspring delivered between 2009 and 2012. Childhood height and weight through age 3 were collected from the medical record and z-scores and body mass index (BMI) were calculated. We assessed the association between GDM treatment and childhood growth using linear mixed modeling. Results: Treatment was divided into medical nutritional therapy (MNT) (n = 293), glyburide (n = 421), and insulin (n = 102). At delivery, birthweight, z-score, and BMI were higher in the offspring of women treated with either glyburide or insulin compared to MNT. However, weight, z-score, and BMI were similar among all offspring at 6 months and 1, 2, and 3 years of age. After controlling for covariates, there were differences in the weight z-score (P = 0.01) over the 3-year period by treatment group, but no differences in weight (P = 0.06) or change in BMI (P = 0.28). Pairwise comparisons indicated that insulin was associated with more weight gain compared with MNT (0.69 kg; 95% CI, 0.10-1.28; P = 0.02) and glyburide was associated with a trend toward lower weight z-score compared with MNT (-0.24; 95% CI, -0.47 to 0.003; P = 0.05). Conclusion: Despite growth differences detected at birth, we observed no meaningful differences in childhood growth from 6 months to 3 years among treatment groups, including in the offspring of women with GDM treated with glyburide.
