The menopausal age is one of the important menopausal factors, and women of different menopausal ages have different risks of diabetes. This study reviewed the evidence from prospective studies on the association between the age at natural menopause and diabetes risk, both domestically and internationally, and presented its research design and main findings. Advanced menopause, especially premature and early menopause, will increase the risk of diabetes in postmenopausal women. The research on the influence of delayed menopause on the incidence of diabetes is still insufficient. Many factors may modify the association between menopausal age and the risk of diabetes.

Objective: To investigate the prevalence levels and trends of overweight and obesity among adult residents in Zhejiang Province from 2015 to 2023, so as to provide a basis for developing regional weight management strategies. Methods: Permanent residents aged ≥18 years from Zhejiang Province who participated in the China Chronic Disease and Risk Factor Surveillance Project in 2015, 2018, and 2023 were selected as survey subjects. Data on sociodemographic information, height, weight and waist circumference were collected through questionnaire surveys and physical examinations. The prevalence of overweight, obesity, and central obesity were calculated and standardized using data from the Seventh National Population Census of Zhejiang Province in 2020. The Cochran-Armitage trend test was employed to analyze the trends in prevalence of overweight, obesity, and central obesity across different genders, ages and regions. Results: A total of 23 902 individuals were surveyed, comprising 10 985 males (45.96%) and 12 917 females (54.04%). Participants were aged ≥60 years, with 13 088 individuals accounting for 54.76%. There were 9 388 urban residents (39.28%) and 14 514 rural residents (60.72%). The standardized prevalence of overweight among residents increased from 30.05% in 2015 to 33.98% in 2023, the standardized prevalence of obesity increased from 7.67% to 15.22%, and the standardized prevalence of central obesity increased from 22.81% to 33.82%, all showed upward trends (all P<0.05). In 2015, 2018, and 2023, the standardized prevalence of overweight was higher in males than in females. In 2018 and 2023, the standardized prevalence of obesity and central obesity were higher in males than in females (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both males and females showed upward trends (all P<0.05). In 2015, 2018 and 2023, the prevalence of central obesity showed an increasing trend with age (all P<0.05). From 2015 to 2023, upward trends were observed in the prevalence of overweight, obesity, and central obesity among residents aged 18-<45 years and aged ≥60 years, as well as in the prevalence of obesity and central obesity among residents aged 45-<60 years (all P<0.05). In 2015, 2018 and 2023, the standardized prevalence of overweight obesity were higher in urban areas than in rural areas, while the standardized prevalence of central obesity was lower in urban areas (all P<0.05). From 2015 to 2023, the standardized prevalence of overweight, obesity, and central obesity among both urban and rural areas showed upward trends (all P<0.05). Conclusion From 2015 to 2023, the prevalence of overweight, obesity, and central obesity among adult residents in Zhejiang Province showed increasing trends, with variations in prevalence levels and trends observed across genders, ages, and urban / rural areas.

Objective:To investigate the pregnancy outcome and the maternal and infant follow-up in the puer-peral period(42 days after delivery)of cesarean section with SARS-CoV-2 Omicron variant in different periods of pregnancy.Methods:330 pregnant women who were diagnosed with SARS-CoV-2 infection and delivered by ce-sarean section in Guangdong Women and Children Hospital from November 20,2022 to January 25,2023 were selected as the research subjects.They were divided into the early(80 cases),middle(151 cases)and late(99 cases)pregnancy group according to the gestational age of infection.The general information,pregnancy compli-cations and comorbidities,pregnancy outcomes,and postpartum maternal and infant follow-up of each group of pregnant women were compared.Results:The clinical classification of pregnant women was asymptomatic and mild,with 9 cases of asymptomatic and 321 cases of mild.The incidence of gestational diabetes mellitus(GDM)in the early and late group was higher than that in the middle group(P＜0.05).There was no statistically significant difference in the incidence of placental abruption,fetal growth restriction,fetal distress,amniotic fluid contamina-tion,preterm labor,postpartum hemorrhage,macrosomia,low-birth-weight infants and the maternal intensive care unit(MICU)transfer rate,newborn birth weight,neonatal asphyxia rate and NICU transfer rate among the three groups(P＞0.05).The incidence of preterm rupture of membranes in the middle group was higher than that in the late group(P＜0.05).Puerperal follow-up results showed that there was no statistically significant difference in the incidence of poor maternal uterine incision healing,poor uterine involution,vaginal microecological imbal-ance and neonatal acute upper respiratory tract infection,pneumonia,digestive system disease,cardiovascular system disease among the three groups(P＞0.05).Conclusions:The majority of pregnant women with Omicron infection during pregnancy are mild.Omicron infection in different periods of pregnancy has no significant effect on pregnancy outcome and puerperal follow-up of cesarean section.No evidence was found that GDM and prema-ture rupture of membranes are significantly associated with Omicron infection in different periods of pregnancy.
