ABSTRACT

Background: Whether coronavirus disease 2019 (COVID-19) pandemic would affect pregnancy-associated factors of uninfected pregnant women was rarely reported.Methods: A total of 32,277 pregnant women from six sites (Hubei Province, Guangdong Province, Hebei Province, Shandong Province, Yunnan Province and Beijing City) were finally recruited. We conducted a retrospective combined cohort study to analyze the associations between the number of prenatal examinations (NPE), delivery gestational week (DGW), the risk of caesarean section (CS), stillbirth, neonatal weight, preterm birth, macrosomia, small for gestational age (SGA), large for gestational age (LGA) and the COVID-19 in two time-periods, the pre-pandemic period (P-2019, 1/1/19-5/31/19) and the pandemic period (P-2020, 1/1/20-5/31/20).Findings: After adjusting for other covariates, we found the NPE, DGW, and SGA were negatively associated with the COVID-19 pandemic, whereas the CS and preterm birth rates were positively associated with the COVID-19, with adjusted relative risks (aRRs) of 1.11 [95% confidence interval (CI) 1.06–1.17] and 1.37 (95% CI: 1.02–1.84) respectively in Hubei. For Guangdong, the associations of CS and preterm birth with the COVID-19 were similar in Hubei. In contrast, limited associations were evident in other areas, except for a positive association with macrosomia [aRR = 1.26 (95% CI: 1.03–1.55)] in Beijing.Interpretation: The CS and preterm birth rates increased slightly in areas that were more affected by the pandemic than other areas among uninfected pregnant women. NPEs were not significantly interrupted and most maternal and neonatal clinical characteristics were within the normal ranges.Funding: National Key Research and Development Program, National Natural Science Foundation of China and National Health Commission Capacity Building and Continuing Education Center.Declaration of Interests: All authors declare to have no conflict of interest.Ethics Approval Statement: The study was approved by the Peking University ethics board (no. IRB00001052-20025).

ABSTRACT

Using the method of sewage epidemiology, the occurrence characteristics and changes of two typical psychoactive drugs methamphetamine and ketamine in the domestic sewage of a city in Guangdong Province during and before and after the new crown epidemic in 2020 were studied, and the mobile phone signaling data was used to analyze The total population, structural characteristics and their change laws were combined to analyze the changes in the consumption of the two drugs during the epidemic and before and after the epidemic. The results show that the actual population of the city during the epidemic decreased by about 45% compared with before the epidemic. The total consumption of various drugs has dropped by about 75% compared to before the epidemic. The significant decline in total consumption was largely caused by the actual population decline during the epidemic. In fact, the per capita consumption levels of methamphetamine and ketamine in the city during the epidemic Compared with the pre-epidemic drop of less than 50%. Taking into account the strict control measures during the epidemic, this decline shows that the abuse of these two psychotropic substances is extremely stubborn;after the epidemic, the consumption of the two drugs and their concentrations in the environment have increased significantly. It has basically returned to the level before the epidemic, which further proves the stubbornness of psychotropic substance abuse.

ABSTRACT

SUMMARY: What is already known about this topic? The coronavirus disease 2019 (COVID-19) pandemic potentially affected prenatal care quality and maternal and fetal outcomes globally.What is added by this report? During COVID-19 pandemic period, the rates of caesarean sections (CS) and preterm birth for uninfected pregnant women increased slightly in areas that were relatively severely impacted by the pandemic in China. The overall number of prenatal examinations did not dramatically decrease, while the eligible examinations significantly decreased in Hubei Province.What are the implications for public health practice? Routine prenatal examinations had been well maintained during the pandemic period in China. In the future, in-time prenatal examinations should be provided to improve the quality of screening and management of high-risk pregnancy under pandemic-affected circumstances. Psychological counseling and transfer treatment channels should be strengthened for pregnant women during lockdown period.
