Objective To systematically review the literature on associations between climate drivers and health outcomes among pregnant people. This review fills a gap by synthesizing evidence for a clinician audience. Data Sources Systematic scoping review of articles published in PubMed and clinicaltrials.gov from January 2010 through December 2023. Study Eligibility Criteria Empirical studies published in English-language peer-reviewed journals, assessing associations between select climate drivers and adverse maternal and birth outcomes. The review included studies examining heat, storms, sea level rise, flooding, drought, wildfires, and other climate-related factors. Health outcomes included preterm birth, low birthweight, small for gestational age, gestational diabetes, pre-eclampsia/eclampsia, miscarriage/stillbirth and maternal mortality. Study Appraisal and Synthesis Methods The scoping review protocol was registered with the International Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY202410004, January 3, 2024) and conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Data were extracted by 2 authors; quality and risk of bias was assessed independently. Results Total of 966 references were screened; 16.35% (k=158) met inclusion criteria. The majority of studies (146/158; 92.4%) documented statistically significant and clinically meaningful associations between climate drivers and adverse perinatal health outcomes, including risk of preterm birth, low birthweight, and stillbirth as well as preeclampsia, gestational diabetes, miscarriage, and maternal death. Among the most durable findings: extreme heat exposure in early and late pregnancy were associated with increased risk of preterm birth and stillbirth. Driven in part by large (often population-based) studies and objective outcomes from surveillance data or medical record reviews, studies in this scoping review were evaluated as high quality (scoring 7-9 on the Newcastle-Ottawa Scale). Risk of bias was generally low. Conclusions Climate drivers are consistently associated with adverse health outcomes for pregnant people. Continuing education for clinicians, and clinician-patient communications should be expanded to address risks of climate change and extreme weather exposure, especially risks of extreme heat in late-pregnancy. Results from this review should inform multilevel interventions to address adverse health effects of climate during pregnancy as well as practice advisories, protocols, checklists, and clinical guidelines in obstetrics.

Rapid urbanization and escalating climate crises place cities at the critical juncture of environmental and public health action. Urban areas are home to more than half of the global population, contributing ~ 75% of global greenhouse gas emissions. Structured surveys were completed by 191 leaders in city governments and civil society from 118 cities in 52 countries (February–April 2024). Data aggregated to report one response per city. The survey utilized framework and indicators established by The 2023 Lancet Countdown on Health and Climate Change. (1) Health hazards, exposures, impacts: two-thirds of cities identify extreme heat, flooding, and air pollution of “high concern,” with health impacts for residents. (2) Adaptation, planning, resilience for health: Although 60% of cities have climate resilience plans, only 22.9% of cities have plans that concurrently address climate and health. Essential resources, municipal systems, and cross-sector collaborations are limited. (3) Mitigation actions and health co-benefits: 90% of cities reported air pollution from multiple sources; only 38% monitor air quality. Energy, food, and transportation systems are sub-optimal to mitigate climate concerns. (4) Economics and finance: 92% of cities report climate change-related economic losses; they plan to increase investments though resources remain constrained. (5) Public and political engagement: City leaders report minimal knowledge sharing among media, national/local government, scientific community, business community, and residents. Results underscore urgency for action and highlight solutions, providing a roadmap for cities to enhance resilience, safeguard public health, and promote social equity.

Objective The objective of this study was to determine the preliminary effectiveness of an intervention to mitigate adverse pregnancy outcomes associated with pre‐pregnancy obesity in American Samoa. Methods We enrolled n = 80 low‐risk pregnant women at <14 weeks' gestation. A complete case analysis was conducted with randomized group assignment (group prenatal care‐delivered intervention vs. one‐on‐one usual care) as the independent variable. Primary outcomes were gestational weight gain and postpartum weight change. Secondary outcomes included gestational diabetes screening and exclusive breastfeeding at 6 weeks post partum. Other outcomes reported include gestational diabetes incidence, preterm birth, mode of birth, infant birth weight, and macrosomia. Results Gestational weight gain was lower among group versus usual care participants (mean [SD], 9.46 [7.24] kg vs. 14.40 [8.23] kg; p = 0.10); postpartum weight change did not differ between groups. Although the proportion of women who received adequate gestational diabetes screening (78.4% group; 65.6% usual care) was similar, there were clinically important between‐group differences in exclusive breastfeeding (44.4% group; 25% usual care), incidence of gestational diabetes (27.3% group; 40.0% usual care), and macrosomia (8.3% group; 29.0% usual care). Conclusions It may be possible to address multiple risk factors related to intergenerational transmission of obesity in this high‐risk setting using a group care‐delivered intervention.

Pregnancy is a universal experience shaped by sociocultural contexts. News media presents a unique opportunity to analyze public narratives of pregnancy and how it differs across cultures. Our study aims to (1) identify the most prevalent overall themes in news media narratives of pregnancy across 19 English-speaking countries, and (2) compare pregnancy narratives across geographic regions. We used the largest English news media corpus that included over 30 million news articles from more than 7000 news websites across 19 countries, and extracted a one-year data subset (2019; 1.5 billion words). Of the primary search terms ‘pregnant’ and ‘pregnancy’, we collated 240,464 descriptors that met criteria of lexical proximity and semantic bonding. Thereafter, we used topic modelling to identify the five most prevalent pregnancy-related themes: (1) complications and risk, (2) crime, (3) celebration, (4) celebrity births, and (5) contraception. Although there were regional differences, themes of complications and risk were most common, comprising 39.6% of all pregnancy narratives in our big-data corpus. The second-most dominant theme was crime (20.8%). Narratives of contraception were more prevalent in Europe, North America, and Oceania (27.2–31.3%) compared to Africa and Asia (11.9–19.6%). Though the vast majority of pregnancies are healthy, themes of complications and risk dominated the news media discourse; unchecked, this may be an avenue for misinformation, stress, and anxiety. In addition, lower prevalence of contraception narratives in Africa and Asia may reflect a gap that requires the attention of policymakers in building culturally-adapted programs to promote family planning and encourage open discussions about sexual health. Results contribute to the academic repository of societal representations of pregnancy through a big-data lens, providing contextual information for future development, implementation and evaluation of localized pregnancy-related campaigns.

Background: Mindful eating is a promising strategy to address problematic eating behaviors; however, little is known about its applicability during pregnancy. No studies have examined the combined effects of mindful and practical eating skills on eating behaviors. Aim: We examined associations between mindful and practical eating skills and eating behaviors (nutritional intake and emotional eating) among pregnant women who received psychoeducation on healthy eating and pregnancies. Methods: Participants were racially-diverse pregnant women (14–42 years) from four clinical sites in Detroit, Michigan, and Nashville, Tennessee (N = 741). We conducted multiple linear regression to examine associations between mindful (hunger cues, satiety cues, mindful check-ins) and practical (food diary/journal, MyPlate method) eating skills and nutritional intake. We calculated residualized change scores to represent changes in the quality of nutritional intake from second to third trimester. We performed multiple logistic regression to examine associations between mindful and practical eating skills and emotional eating. Results: Women improved over time in eating behaviors (better nutrition, less emotional eating). Regular use of MyPlate was associated with better nutritional intake (unstandardized coefficient [B] = −0.61), but food diaries were not. We found a significant interaction in predicting emotional eating: For those regularly paying attention to hunger cues, some use of MyPlate (Adjusted Odds Ratio [AOR] = 0.39) and especially regular use of MyPlate (AOR = 0.13) reduced the likelihood of emotional eating during pregnancy. Conclusion: Enhancing both mindful and practical eating skills, such as paying attention to hunger cues, and using the MyPlate method, may facilitate pregnant women's ability to improve their eating behaviors.

Background Group prenatal care enhances quality of care, improves outcomes, and lowers costs. However, this healthcare innovation is not widely available. Using a case-study approach, our objectives were to (1) examine organizational characteristics that support implementation of Expect With Me group prenatal care and (2) identify key factors influencing adoption and sustainability. Methods We studied five clinical sites implementing group prenatal care, collecting qualitative data including focus group discussions with clinicians (n = 4 focus groups, 41 clinicians), key informant interviews (n = 9), and administrative data. We utilized a comparative qualitative case-study approach to characterize clinical sites and explain organizational traits that fostered implementation success. We characterized adopting and non-adopting (unable to sustain group prenatal care) sites in terms of fit for five criteria specified in the Framework for Transformational Change: (1) impetus to transform, (2) leadership commitment to quality, (3) improvement initiatives that engage staff, (4) alignment to achieve organization-wide goals, and (5) integration. Results Two sites were classified as adopters and three as non-adopters based on duration, frequency, and consistency of group prenatal care implementation. Adopters had better fit with the five criteria for transformational change. Adopting organizations were more successful implementing group prenatal care due to alignment between organizational goals and resources, dedicated healthcare providers coordinating group care, space for group prenatal care sessions, and strong commitment from organization leadership. Conclusions Adopting sites were more likely to integrate group prenatal care when stakeholders achieved alignment across staff on organizational change goals, leadership buy-in, and committed institutional support and dedicated resources to sustain it.
