Background: China was the first country in the world to experience a large-scale COVID-19 outbreak. The rapid spread of the disease and enforcement of public health measures has caused distress among vulnerable populations such as pregnant women. With a limited understanding of the novel, emerging infectious disease, pregnant women have sought ways to access timely and trusted health care information. The mental health status of pregnant women during this public health emergency, as well as how they responded to the situation and where and how they obtained antenatal care information, remain to be understood. Objective: This study aimed to evaluate the mental health status of pregnant women during the COVID-19 epidemic in China by measuring their perceived stress, anxiety, and depression levels; explore the approaches used by them to access antenatal health care information; and determine their associations with maternal mental health status. Methods: We conducted a web-based, cross-sectional survey to assess the mental health status of Chinese pregnant women by using the validated, Chinese version of Perceived Stress Scale, Self-Rating Anxiety Scale, and Edinburgh Depression Scale. We also collected information on the various approaches these women used to access antenatal care information during the early stage of the COVID-19 epidemic, from February 5 to 28, 2020. Results: A total of 1873 pregnant women from 22 provinces or regions of China participated in the survey. The prevalence of perceived stress, anxiety, and depression among these participants was 89.1% (1668/1873; 95% CI 87.6%, 90.4%), 18.1% (339/1873; 95% CI 16.4%, 19.9%), and 45.9% (859/1873; 95% CI 43.6%, 48.1%), respectively. Hospitals’ official accounts on the Chinese social media platforms WeChat and Weibo were the most popular channels among these pregnant women to obtain antenatal care information during the COVID-19 outbreak. Access to antenatal care information via the hospitals’ official social media accounts was found to be associated with a significantly lower risk of perceived stress (adjusted odds ratio [aOR] 0.46, 95% CI 0.30-0.72; P=.001), anxiety (aOR 0.53, 95% CI 0.41-0.68; P<.001), and depression (aOR 0.73, 95% CI 0.59-0.91; P=.005). Access to health care information via hospital hotlines or SMS was found to be significantly associated with a lower risk of anxiety only (OR 0.77, 95% CI 0.60-0.98; P=.04). Conclusions: During the COVID-19 outbreak in China, pregnant women experienced high levels of perceived stress, anxiety, and depression. During such public health emergencies, mental health care services should be strengthened to reassure and support pregnant women. Specific information targeted at pregnant women, including information on how to cope in an emergency or major disease outbreak, developed and disseminated by health care institutions via social media platforms could be an effective way to mitigate mental health challenges and ensure epidemic preparedness and response in the future.

Background: Evidence on the association between exposure to perfluoroalkyl and polyfluoroalkyl substances (PFASs) and blood glucose concentrations in pregnant women is inconsistent. This study aimed to examine the association between PFAS exposure and the concentrations of fasting plasma glucose (FPG) and one-hour plasma glucose (1 h-PG) after a 50-g oral glucose tolerance test in pregnant women. Methods: The study was based on the Shanghai-Minhang Birth Cohort, in which 1292 pregnant women were recruited. Among them, 981 women provided blood samples (at 12–16 gestational weeks) for PFAS measurement. FPG data collected from 856 women at 12–20 GW and 1 h-PG data collected from 705 women at 20–28 GW were obtained through medical records from the routine prenatal care system. High FPG or 1 h-PG was defined as ≥90th percentile of FPG or 1 h-PG. The analysis of eight PFASs was conducted in this study: perfluorohexane sulfonate (PFHxS), perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorodecanoic acid (PFDA), perfluoroundecanoic acid (PFUdA), perfluorododecanoic acid (PFDoA), and perfluorotridecanoic acid (PFTrDA). The odds ratios (ORs) and associated 95% confidence intervals (CIs) were estimated to determine the associations of each PFAS compound with high FPG and 1 h-PG from a logistic regression model. Results: After adjustment for potential confounders, most PFASs were positively associated with high 1 h-PG concentrations. The OR for high 1 h-PG concentrations was 1.87 (95% CI: 1.15–3.05) with a one log unit increase of PFOS; similar associations were observed for PFNA (OR: 2.15, 95% CI: 1.24–3.74), PFDA (OR: 1.61, 95% CI: 1.10–2.44), PFUdA (OR: 1.71, 95% CI: 1.12–2.62), and PFDoA (OR: 1.34, 95% CI: 1.00–1.81). When the PFAS concentrations were categorized into three groups by tertiles, the highest tertiles of PFOS, PFOA, PFNA, PFDA, PFDoA, and PFTrDA had a statistically significant increase in the risk of high 1 h-PG concentrations compared with the lowest tertiles. No statistically significant association was observed between PFAS exposure and high FPG. Conclusion: PFAS exposure was associated with an increased risk of high 1 h-PG among pregnant women, but no such association was observed for FPG.

Unintended pregnancy and induced abortion among young (unmarried or nulliparous) women have become serious social and health issues in China, which are thought to partly result from low use of long-acting reversible contraception, such as intrauterine devices (IUDs). Considering that providers may play an especially important role in increasing use of this particular method, we investigated Chinese health care providers’ attitudes and practices regarding IUDs use for nulliparous women, and further examine the potential factors and reasons contributing to their attitudes and practices. We recruited health care providers at two Chinese national academic conferences and surveyed them about knowledge of IUDs, willingness to recommend IUDs to nulliparous women, and their related practices. Modified Poisson regression was used to examine the potential factors related to their attitudes and practices. Approximately a half of respondents reported unwillingness to recommend IUDs to nulliparous women. Providers with more misperceptions about the safety and contraindications were more likely to be unwilling to recommend IUDs to nulliparous women. Moreover, 71.0% of respondents rarely or never recommended or provided IUDs to nulliparous women. Providers’ unwillingness to recommend IUDs to nulliparous women was associated with their infrequent practices (aPR=1.43; 95% CI: 1.04, 1.96). In addition to concerns about the side effects or complications, traditional sexual concept against premarital sex was often cited as a reason by Chinese health providers for their negative attitudes towards IUDs use for nulliparous women, a large proportion of whom are unmarried. Our findings suggest that negative attitudes and infrequent practices regarding IUDs use for nulliparous women are common in Chinese health care providers. Moreover, misperceptions about IUDs, as well as traditional sexual concept, contribute to Chinese health care providers’ negative attitudes towards IUDs use for nulliparous women, and may further reduce their provision. Educational interventions are needed to improve providers’ accurate knowledge of IUDs and fill the gap between traditional sexual concept and young women’s needs of contraceptive services.

Background: Spontaneous pregnancy loss (SPL) precedes an increased risk of reduced fertility, while its etiology mechanism remains largely unknown. Liver dysfunction presenting in early pregnancy may represent a pre-existing undiagnosed liver condition affecting fetal development. Here, we investigated whether maternal abnormal liver function in early pregnancy contributed to the incidence of SPL.Methods: Data on pregnant women were leveraged from the Maternal Health Care Information System in Shanghai City from 2017 to 2021. Liver dysfunction status was defined as having any elevated liver function biomarker levels (LFBs) at the first antenatal visit. SPL cases were defined as fetal death occurring before 28 weeks gestation. Generalized linear models were used to estimate crude and adjusted risk ratios (aRRs) and 95% confidence intervals (CIs).Results: Among 10175 leveraged pregnant women, 918 (9.0%) SPL cases were recorded. Maternal liver dysfunction in early pregnancy was associated with a 49% increased risk of SPL (RR 1.49, 95% CI 1.22–1.84). This positive association persisted after adjustment for covariates (aRR 1.55, 95% CI 1.26–1.92). Higher γ-glutamyl transferase (GGT) and alkaline phosphatase (ALP) levels were also linked with increased risk of SPL in a linear fashion (aRRs per 1 standard deviation increase: 1.13, 95% CI 1.08–1.17; 1.13, 1.07–1.20, respectively). Similar magnitudes of associations were observed between normal weight and overweight pregnant women in subgroup analysis.Conclusion: We provide new evidence that maternal abnormal liver function in early pregnancy, as well as GGT and ALP, predisposes to an increased risk of SPL.

Importance: The interpregnancy intervals are suboptimal worldwide, and women lack access to high-quality postpartum contraceptive services in China.Objective: To evaluate the effectiveness of integrating postpartum contraceptive interventions into the existing maternal and child health care (MCH) system.Design, Setting, and Participants: This cluster randomized trial randomly allocated 13 communities in Minhang District in Shanghai, China, to the intervention or the control group. Data were collected between September 2020 and February 2023. Eligible participants included women who registered their pregnancy in community health centers and were followed up to 1 year post partum. Data analysis was conducted from April 2023 to May 2024.Interventions: Participants in the intervention group received postpartum contraception consultations, online educational videos, a 45-minute class, health prescriptions, and educational pamphlets at 5 stages in alignment with the MCH system of China. The control group received routine MCH services.Main Outcomes and Measures: The primary outcome was incidence of unintended pregnancy within 1 year after childbirth. The secondary outcomes included knowledge level of postpartum contraception, utilization rate of reliable long-acting reversible contraception (LARC), and incidence of induced abortion.Results: A total of 1279 participants (698 in intervention from 7 clusters and 581 in control from 6 clusters) were recruited, and 995 (521 older than 30 years [40.7%]; 539 intervention [54.2%] and 456 control [45.8%]) completed the trial. The incidence of unintended pregnancy, LARC utilization, and induced abortion within 1 year after childbirth was 1.5% (8 participants), 3.2% (17 participants), and 0.6% (3 participants), respectively, in the intervention group, and 3.9% (18 participants), 1.1% (5 participants), and 2.0% (9 participants), respectively, in the control group. Participants in the intervention group were significantly less likely to experience unintended pregnancy (adjusted odds ratio [aOR], 0.33; 95% CI, 0.16-0.70), had a higher rate of LARC utilization (aOR, 2.47; 95% CI, 1.02-5.98), and a lower rate of induced abortion due to unintended pregnancy (aOR, 0.30; 95% CI, 0.09-0.99). The postpartum contraception knowledge level in the intervention group was substantially higher than the control group (β = 24.20; 95% CI, 20.92-27.47).Conclusions and Relevance: This cluster randomized clinical trial demonstrated the designed postpartum contraceptive interventions were effective in reducing unintended pregnancy and induced abortion and increasing postpartum contraception knowledge and LARC utilization among women at 1-year post partum.Trial Registration: Chictr.org.cn Identifier: ChiCTR2000034603

This study investigates the effectiveness of information technology–based 2-way referral in the diagnosis and management of cervical lesions in Minhang District, Shanghai, China. Women who underwent screening for cervical lesions in 4 community health centers constituted the intervention group, whereas women from the other 9 community health centers were included as controls. The diagnosis rate of cervical lesions was higher in the intervention group (7.61%) than in the control group (0.36%; P = .000). The diagnosis rate of early cervical lesion was 97.11% in the intervention group and 85.71% in the control group, showing no statistically significant differences (P = .080). However, early diagnosis rate of precancerous lesion was much higher in the intervention group (95.45%) compared with the control group (64.29%; P = .001). In conclusion, higher effectiveness of early diagnosis and management of cervical lesions was observed in the intervention group compared with the control group.
