Introduction and Objective: Excess gestational weight gain (GWG) is common and increases risk for gestational diabetes (GDM), obesity, diabetes. We assessed whether Healthy for Two, a virtual behavioral intervention in prenatal care clinics, vs. usual prenatal care, reduces GWG and GDM among women with pre-pregnancy overweight/obesity using a pragmatic randomized controlled trial design.Methods: Eligibility was […]

Introduction and Objective: To date, limited long-term evidence links depressive symptoms to subsequent glycated hemoglobin (HbA1c) trajectories in youth and young adults (YYAs) with youth-onset type 1 diabetes (T1D). We explored the within- and between-person associations of depressive symptoms and changes therein with HbA1c in YYAs with T1D.Methods: We analyzed longitudinal data from the SEARCH […]

Introduction and Objective: Health care has become unaffordable for many diabetes patients. We examined 3-year health effects of: (1) Preventive Drug List (PDL) benefits that set drug cost sharing to $0, including for insulin, GLP-1 RA, & SGLT2i; (2) switches from high-deductible (HDHP; ≥$1000) to low-deductible health plans (LDHP; ≤$500) that broadly reduce cost sharing […]

Introduction and Objective: Metabolic inflexibility, or an inability to switch between fat and carbohydrate oxidation, has not been thoroughly investigated in T1D despite its close link with skeletal muscle insulin resistance—an established feature of T1D. We investigated whether T1D is characterized by metabolic inflexibility relative to controls without diabetes, and whether physical activity (PA), sedentary […]

Introduction and Objective: T2D is characterized by increased rates of endogenous glucose production (VEGP) and hepatic insulin resistance, which are strongly linked with MASLD and potential alterations in hepatic mitochondrial function. Because there is limited direct evidence for this in humans we assessed rates of hepatic mitochondrial oxidation [citrate synthase (VCS)] flux and contributions of […]

Introduction and Objective: Advancements in stem-cell treatment (SCT) offer hope of a cure for type 1 diabetes (T1D). As SCT trials progress, it is important to understand why adults with T1D do or do not pursue SCT, especially in the context of advanced diabetes technology use. Our aim was to explore factors influencing pursuit of […]

Introduction and Objective: Hepatic steatosis is closely linked to obesity, insulin resistance, and type 2 diabetes mellitus (T2DM). However, the relative contributions of obesity versus portal insulin exposure to liver fat accumulation remain unclear. We examined the relationship between liver fat content, body mass index (BMI), and portal insulin concentration in individuals with type 1 […]

Introduction and Objective: Human evidence is lacking on whether added sugar intake affects liver function via gut microbes. We examined associations of added sugar intake from desserts, a major added sugar source, with liver fibrosis (FIB-4), MRI liver fat (PDFF) and inflammation (native T1), gut microbiota, and metabolites in Hispanic Community Health Study/Study of Latinos […]

Introduction and Objective: Subtypes of gestational diabetes mellitus (GDM) have been described but their association with subsequent maternal cardiometabolic health remains uncertain. We examined whether GDM subtypes were differentially associated with cardiometabolic health 10-14 years after delivery.Methods: An exploratory secondary analysis from the prospective Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study (HAPO FUS). GDM was […]
