ABSTRACT
Objective: To describe fertility and explore factors associated with it among pre-conception couples of childbearing age. Methods: Based on the pre-conceptional offspring trajectory study of the School of Public Health of Fudan University, couples of childbearing age who participated in the pre-conception physical examination in Shanghai Jiading District from 2016 to 2021 were recruited and followed up. Couples' time to pregnancy (TTP) was analyzed and Cox proportional hazards regression model was used to explore the factors associated with TTP. Kaplan-Meier was used to calculate each menstrual cycle's cumulative pregnancy rate. Results: A total of 1 095 preconception couples were included in the analysis, the M(Q1,Q3)of TTP was 4.33 (2.41, 9.78) menstrual cycles. Age of women (FR=0.90, 95%CI: 0.85-0.95, P<0.001), women who were overweight or obese before pregnancy (FR=0.36, 95%CI: 0.24-0.55, P<0.001), women who were exposed to second-hand smoking (FR=0.63, 95%CI: 0.44-0.92, P=0.016), women whose home or office had been renovated in the past 2 years and had a particular smell (FR=0.46, 95%CI: 0.26-0.81, P=0.008) were risk factors for impaired fertility. Regular menstrual cycles (FR=1.64, 95%CI: 1.16-2.31, P=0.005), females who often drank tea/coffee (FR=1.55, 95%CI: 1.11-2.17, P=0.011) and males who took folic acid before conception (FR=2.35, 95%CI: 1.38-4.23, P=0.002) were associated with better fertility. The cumulative pregnancy rate of 3, 6, and 12 menstrual cycles was 37.6%, 64.4%, and 78.4%, respectively. Conclusion: Older couples, overweight or obesity before pregnancy, irregular menstruation, exposure to secondhand smoke and decoration pollutants in females are associated with impaired fertility. Frequent tea/coffee drinking before pregnancy in females and taking folic acid before pregnancy in males are associated with shortened conception time.

Objective:To explore the relationship between breastfeeding knowledge， self-efficacy and exclusive breastfeeding behavior among mothers of one-month old babies. Methods:Random sampling method was conducted for choosing 5 out of 13 community service health centers in Jiading district of Shanghai. A cross-sectional online survey was conducted among the mothers. Results:A total of 456 valid questionnaires were received， the full score of breastfeeding knowledge was set at 60， with an average of 47.17±5.65， ranging from 12 to 60. The full score of self-efficacy was set at 70， with an average of 47.70±14.48， ranging from 14 to 70. The exclusive breastfeeding rate of one-month old infants was 55.3%（252/456）. Multivariate logistic analysis showed that mothers with higher scores of breastfeeding knowledge had significantly higher rate of exclusive breastfeeding （OR=1.717， 95%CI 1.034-2.851， P=0.037）. Those with higher scores of breastfeeding self-efficacy also had significantly higher rate of exclusive breastfeeding （OR=5.736， 95%CI 3.455-9.522， P=0.001）. Conclusions:The breastfeeding knowledge and self-efficacy of mothers of one-month old babies were significantly associated with the rate of exclusive breastfeeding. Medical staff should strengthen the delivery and cultivation of breastfeeding knowledge and skills for mothers to improve breastfeeding self-efficacy， and ultimately promote the rate of exclusive breastfeeding.
ABSTRACT
Objective To investigate the current situation of the exercise, relevant knowledge and impact factors in pregnant women during pregnancy, providing references to instruct pregnant women to do suitable exercise. Methods Self-designed questionnaires were used to investigate the exercise behavior and cognition in 3 099 pregnant women who visited the clinic for first-time prenatal examination at Jiading District of Shanghai. Results It was found in investigation that 65.21% pregnant women often did exercise, of whom 29.14% did less than 20 minutes exercise every time, while 60.96% did 20 to 40 minutes, and 9.90% did more than 40 minutes.Slow-walking was the majority choice, which counted for 87.14% in pregnant women.And 34.79% pregnant women did not do exercise, mainly due to "wouldn't like to do exercise" or "don't have time for it".Age, body mass index (BMI), educational level with the pregnant women as well as their husbands impact factors related to their exercise behavior during pregnancy (P<0.01). Conclusion At present, pregnant women exercise mode is unitary during pregnancy.Doctors and nurses should advocate more on health education for them, and family members should be involved in health education program as well.We should improve the education health system and give full play to the advantages of the Internet, train obstetricians, nutritionists, community doctors and other weight management professionals, improve service capabilities, and instruct pregnant women to choose safe and effective exercise during pregnancy.
