Abstract Racial inequities in postpartum weight have been documented with limited studies on the influences of racism and other forms of discrimination. In a prospective longitudinal study applying ecological momentary assessment (EMA) and ambulatory assessment of weight, we measured the association between discrimination, stress, and postpartum weight change. The Postpartum Mothers Mobile Study is a cohort of 313 pregnant and birthing individuals who were followed during their second and third trimesters through 1 year postpartum. They were recruited in clinical settings between 2017 and 2020 in a major city center in Pennsylvania. Measures of racism and gender-based discrimination were collected via random EMA surveys throughout pregnancy and postpartum, and weight was collected via Bluetooth-enabled scales at least weekly. Among Black participants, a 10% increase in the number of days a participant experienced racial discrimination in the past month was associated with retaining 0.3 more pounds, a 10% increase in EMA gender discrimination was associated with retaining 0.4 more pounds, and EMA stress reported in the past month was associated with decreased weight retention. Chronic experiences of racial and gender discrimination may contribute to weight retention immediately after pregnancy and beyond.

ImportancePreventing diabetes complications requires monitoring and control of hyperglycemia and cardiovascular risk factors. Switching to high-deductible health plans (HDHPs) has been shown to hinder aspects of diabetes care; however, the association of HDHP enrollment with microvascular and macrovascular diabetes complications is unknown.ObjectiveTo examine the association between an employer-required switch to an HDHP and incident complications of diabetes.Design, Setting, and ParticipantsThis retrospective cohort study used deidentified administrative claims data for US adults with diabetes enrolled in employer-sponsored health plans between January 1, 2010, and December 31, 2019. Data analysis was performed from May 26, 2022, to January 2, 2024.ExposuresAdults with a baseline year of non-HDHP enrollment who had to switch to an HDHP because their employer offered no non-HDHP alternative in that year were compared with adults who were continuously enrolled in a non-HDHP.Main Outcomes and MeasuresMixed-effects logistic regression models examined the association between switching to an HDHP and, individually, the odds of myocardial infarction, stroke, hospitalization for heart failure, lower-extremity complication, end-stage kidney disease, proliferative retinopathy, treatment for retinopathy, and blindness. Models were adjusted for demographics, comorbidities, and medications, with inverse propensity score weighting used to account for potential selection bias.ResultsThe study included 42 326 adults who switched to an HDHP (mean [SD] age, 52 [10] years; 19 752 [46.7%] female) and 202 729 adults who did not switch (mean [SD] age, 53 [10] years; 89 828 [44.3%] female). Those who switched to an HDHP had greater odds of experiencing all diabetes complications (odds ratio [OR], 1.11; 95% CI, 1.06-1.16 for myocardial infarction; OR, 1.15; 95% CI, 1.09-1.21 for stroke; OR, 1.35; 95% CI, 1.30-1.41 for hospitalization for heart failure; OR, 2.53; 95% CI, 2.38-2.70 for end-stage kidney disease; OR, 2.23; 95% CI, 2.17-2.29 for lower-extremity complication; OR, 1.17; 95% CI, 1.13-1.21 for proliferative retinopathy; OR, 2.35; 95% CI, 2.18-2.54 for blindness; and OR, 2.28; 95% CI, 2.15-2.41 for retinopathy treatment).Conclusions and RelevanceThis study found that an employer-driven switch to an HDHP was associated with increased odds of experiencing all diabetes complications. These findings reinforce the potential harm associated with HDHPs for people with diabetes and the importance of affordable and accessible chronic disease management, which is hindered by high out-of-pocket costs incurred by HDHPs.

OBJECTIVE To determine the relative hazards of acute and chronic diabetes complications among people with diabetes across the U.S. rural-urban continuum. RESEARCH DESIGN AND METHODS This retrospective cohort study used the OptumLabs Data Warehouse, a deidentified data set of U.S. commercial and Medicare Advantage beneficiaries, to follow 2,901,563 adults (age ≥18 years) with diabetes between 1 January 2012 and 31 December 2021. We compared adjusted hazard ratios (HRs) of diabetes complications in remote areas (population <2,500), small towns (population 2,500–50,000), and cities (population >50,000). RESULTS Compared with residents of cities, residents of remote areas had greater hazards of myocardial infarction (HR 1.06 [95% CI 1.02–1.10]) and revascularization (HR 1.04 [1.02–1.06]) but lower hazards of hyperglycemia (HR 0.90 [0.83–0.98]) and stroke (HR 0.91 [0.88–0.95]). Compared with cities, residents of small towns had greater hazards of hyperglycemia (HR 1.06 [1.02–1.10]), hypoglycemia (HR 1.15 [1.12–1.18]), end-stage kidney disease (HR 1.04 [1.03–1.06]), myocardial infarction (HR 1.10 [1.08–1.12]), heart failure (HR 1.05 [1.03–1.06]), amputation (HR 1.05 [1.02–1.09]), other lower-extremity complications (HR 1.02 [1.01–1.03]), and revascularization (HR 1.05 [1.04–1.06]) but a smaller hazard of stroke (HR 0.95 [0.94–0.97]). Compared with small towns, residents of remote areas had lower hazards of hyperglycemia (HR 0.85 [0.78–0.93]), hypoglycemia (HR 0.92 [0.87–0.97]), and heart failure (HR 0.94 [0.91–0.97]). Hazards of retinopathy and atrial fibrillation/flutter did not vary geographically. CONCLUSIONS Adults in small towns are disproportionately impacted by complications of diabetes. Future studies should probe for the reasons underlying these disparities.

Importance Preeclampsia is one of the most serious health problems that affect pregnant persons. It is a complication in approximately 4% of pregnancies in the US and contributes to both maternal and infant morbidity and mortality. Preeclampsia also accounts for 6% of preterm births and 19% of medically indicated preterm births in the US. There are racial and ethnic disparities in the prevalence of and mortality from preeclampsia. Non-Hispanic Black women are at greater risk for developing preeclampsia than other women and experience higher rates of maternal and infant morbidity and perinatal mortality. Objective To update its 2014 recommendation, the USPSTF commissioned a systematic review to evaluate the effectiveness of low-dose aspirin use to prevent preeclampsia. Population Pregnant persons at high risk for preeclampsia who have no prior adverse effects with or contraindications to low-dose aspirin. Evidence Assessment The USPSTF concludes with moderate certainty that there is a substantial net benefit of daily low-dose aspirin use to reduce the risk for preeclampsia, preterm birth, small for gestational age/intrauterine growth restriction, and perinatal mortality in pregnant persons at high risk for preeclampsia. Recommendation The USPSTF recommends the use of low-dose aspirin (81 mg/d) as preventive medication for preeclampsia after 12 weeks of gestation in persons who are at high risk for preeclampsia.
