“…Further studies needed to explore the underlying reasons led to the skip of regular check-ups. In addition, one study also suggested the lockdown policy may interfere with the circadian rhythm of women and fetuses, which may have led to several adverse pregnancy outcomes and may result in CS [27]. These results advocate that more medical support and more targeted guidance should be implemented in severely affected regions.…”

Background Improving and maintaining the health of mothers and newborns is indisputably a global priority, especially during a pandemic. This study intends to examine the factors associated with cesarean section (CS) during lockdown time. Methods A total of 678 women who just gave birth within 7 days were enrolled from maternal and children hospitals in nine cities of China from April to May 2020. The delivery modes and potential influencing factors were investigated. The subgroup analysis and sensitivity analysis were used to examine the association of CS and risk factors among populations with different characteristics and to control for possible confounding, respectively. Results The overall rate of cesarean delivery was 37.3%. In multi-variant model, maternal age > 30 years (OR, 95% CI = 1.71, 1.21–2.41), higher pre-gestational BMI (OR, 95% CI = 1.16, 1.10–1.23), living in regions with confirmed COVID-19 cases > 500 (OR, 95% CI = 2.45, 1.74–3.45), and excess gestational weight gain (OR, 95% CI = 1.73, 1.17–2.55) were associated with cesarean delivery. These trends of associations were not changes in sensitivity analysis and subgroup analysis. Cesarean delivery occurred more in women who got more nutrition instruction during the pandemic period in the univariant model; however, this association showed insignificance in the multiple-variant analysis. Conclusion A high cesarean delivery rate was found in uninfected women who experienced lockdown in their third trimester. During the COVID-19 pandemic, more medical support should be provided in severely affected regions to ensure and promote health in pregnancy.

“…Thus, we speculated that anxiety or other factors during the lockdown made the maternal diet style change, resulting in excessive nutrient transport to the fetus and placenta which further leading to fetal macrosomia. Studies have found that moderate exercise is helpful to improve GDM condition, especially bene ting from walking [27][28][29]. The light regulation of circadian rhythm has also been found to be essential for fetal development.…”

Aims: This study was to evaluate the effects of the home quarantine on pregnancy outcomes of gestational diabetes mellitus (GDM) patients during the COVID-19 outbreak.Methods: Thecomplete electronic medical records of GDM patients with home quarantine history were collected and classified into the home quarantine group from 24 February 2020 to 24 November 2020. The same period of GDM patients without home quarantine historywas included in the control group from 2018 and 2019.Results: A total of 1358 GDM patients were included in the analysis, including 484 in 2018, 468 in 2019, and 406 in 2020. GDM patients with home quarantine in 2020 had higher glycemic levels and worse pregnancy outcomes than 2018 and 2019, including higher cesarean section rate,lower Apgar scores, and higher incidence of macrosomia and nuchal cord. More importantly, the second trimester of home quarantine had brought a broader impactto pregnant women and fetuses.Conclusion: Home quarantine has aggravated the condition of GDM pregnant women and brought more adverse pregnancy outcomes during the COVID-19 outbreak. Therefore, we suggested that governments and hospitals should strengthen lifestyle guidance, glucose management, and antenatal care for GDM patients with home quarantine during public health emergencies.

“…According to the previous studies, chronic changes during the daytime photoperiod are enhanced by artificial light during nighttime [8]. Change in photoperiod, as indicated by the longtime light exposure which occurred in lockdown during Covid-19, may alter the function of all body organs, according to Bagic et al [13]. However, several questions are arising in this regard.…”

“…There are scanty studies concerning the effects of lockdown on change in circadian rhythm and its hazardous effects on metabolic status. However, in one study, Bagci and colleagues (2020) have emphasized that chronic photoperiod change during lockdown may dramatically affect different organs of the fetus body during its development [13]. According to the previous studies, chronic changes during the daytime photoperiod are enhanced by artificial light during nighttime [8].…”

Covid-19 pandemic forced the governments to choose the policy to the lockdown the gathering centers , including universities and schools to prevent the rapid spread of the disease, forcing millions of people to stay at home for several weeks and even more. Staying in the home for such long periods is associated with a change in the wake/sleep period (a kind of social jet lag) and the resulting alteration in feeding time and type of food. Moreover, the prevalence of anxiety and depression resulted from the reduction in physical activity and bad news also may help to worsen the social jetlag effect on these parts of society. Possible hazardous changes in this factor are reviewed in this study and some suggestions for better management of this condition are also offered. Pubmed, SCOPUS, WOS, and Google Scholar data banks were searched using the following keyword in combination and/or alone: jetlag, social jetlag, Chronobiology, photoperiod, metabolic disease, cardiovascular, sleep/weak period. Longtime lockdown gathering centers are shown to change the photoperiod cycle in people, and it may induce several consequences, including the effects on cognitive brain function, induce mental illness, metabolic syndrome, insulin resistance, mitochondrial aging, and cardiovascular diseases. Considering these facts, it is important to make rehabilitation programs for all the societies' members for post-pandemic time.
