Measurement of Health-Related Quality of Life from Conception to Postpartum Using the EQ-5D-5L Among a National Sample of US Pregnant and Postpartum Adults.

BACKGROUND: During pregnancy, physiological changes occur from conception to birth. We assessed the health-related quality of life (HRQoL) throughout pregnancy and postpartum using the EQ-5D-5L. METHODS: Between May and July 2021 (wave 1) and December 2021 and April 2022 (wave 2), we conducted a series of cross-sectional, national online surveys of 5250 pregnant and postpartum United States (US) adults. The survey included the EQ-5D-5L, EQ visual analog scale (EQ VAS), items measuring respondents' sociodemographic and health information, last menstrual period, estimated date of delivery, and date of pregnancy end (if postpartum). We examined monthly EQ-5D-5L items, utility values, and EQ VAS scores during pregnancy and postpartum. We used quantile regression adjusted for calendar month of last menstrual period to estimate changes in HRQoL at different time points of pregnancy and postpartum. RESULTS: There was a steady increase in the frequency of respondents reporting health-related problems and a decline in EQ-5D-5L utility values from early pregnancy until the ninth month of pregnancy (ß = - 0.21; standard error [SE] 0.02; P < 0.001), followed by a 0.10 (SE 0.02; P < 0.001) unit increase in values during the first postpartum month and a stabilization during the remainder of the postpartum period (ß = 0.02; SE 0.02; P = 0.214). The median EQ-5D-5L utility value was lowest during the ninth month of pregnancy (median 0.78 [interquartile range 0.30]). CONCLUSIONS: HRQoL as measured by EQ-5D-5L varies across pregnancy, indicating progressive declines throughout pregnancy and a return to first trimester values during the first month postpartum. Studies involving HRQoL measurement in pregnant people should account for the stage of pregnancy in their estimates.

COVID-19 vaccine coverage among college students following vaccine mandates.

OBJECTIVE: Colleges are potential hotspots for transmission of SARS-CoV-2 due to lower immunization rates and possible close contacts among young adults. Some universities have implemented policies mandating COVID-19 vaccination; however, their effects remain uncertain. We estimated COVID-19 vaccination rates with and without university-mandated vaccination policies. PARTICIPANTS: A university-wide survey was conducted among 2,011 students. METHODS: Students completed an online questionnaire on sociodemographics, COVID-19 vaccine status, and vaccine intention. RESULTS: Without university vaccine mandates, 76% of students would receive a COVID-19 vaccination, and with vaccine mandates, more than 82% of students would receive vaccination. Despite this improvement, we observed fewer changes in vaccine coverage for certain subgroups of students, indicating these policies could exacerbate ongoing disparities in COVID-19 vaccination rates. CONCLUSIONS: COVID-19 vaccine mandates on campuses are likely to increase vaccination rates modestly. However, interventions will likely be required to supplement vaccine mandates.

Uptake and Perceptions of COVID-19 Vaccines Among US Pregnant Women

Background Compared to the non-pregnant population, pregnant persons are at increased risk for severe COVID-19 related illness, including higher rates of admission to intensive care and greater mortality. Despite the potential benefits of COVID-19 vaccines for pregnant persons, current guidelines for the use of COVID-19 vaccines during pregnancy are limited, and the uptake of COVID-19 vaccines among US pregnant adults is unclear. Methods As part of an ongoing national longitudinal cohort study, 1,372 pregnant and recently postpartum pregnant persons participated in an online baseline survey, including questions on COVID-19 vaccination status and perceptions of COVID-19 vaccines. Preliminary analyses were restricted to 1,041 individuals who were pregnant during vaccine availability (after 14 December 2020). Post-stratification survey weights were applied to ensure results are representative of the general population. Weighted percentages and odds ratios were estimated based on survey responses. Results 39.4% (95% CI 33.7, 45.1%) of respondents received a COVID-19 vaccine during pregnancy. Predictors of vaccination included belief that COVID-19 was a serious disease (OR 2.49;95% CI 1.41, 4.11) and concerns about giving birth during the COVID-19 pandemic (OR 1.83, 95% CI 1.10, 3.04). The most common reason for receiving a COVID-19 vaccine was to protect themselves (21.2%) or their baby (39.1%). Among unvaccinated respondents, 14.9% planned to receive a vaccine during their pregnancy and 35.3% after pregnancy, 28.6% had no intention of receiving a vaccine, and the remaining 21.1% were uncertain. Among those who never planned to vaccinate, the most common reason was concern about side effects (57.2%). Percent of pregnant persons receiving at least one dose of COVID-19 vaccine, by month of delivery (postpartum participants) or estimated month of delivery (pregnant participants). Conclusion Our results indicate that despite the lack of clear recommendations for vaccination during pregnancy, more than one-third of pregnant persons received a COVID-19 vaccine during pregnancy. Evaluation of the health effects of COVID-19 vaccination during pregnancy, including the ability to protect pregnant persons and their infants from infection, is needed.
