BackgroundThis study aimed to describe the intentions of and barriers to the use of long-acting reversible contraceptives (LARCs) in the post-abortion period among women seeking abortion in mainland China.MethodsA cross-sectional study was conducted from July 2015 to December 2015 using a waiting room questionnaire. A total of 381 women seeking abortions were recruited at a public hospital abortion clinic. The outcome variable was an ‘intention-to-use’ LARCs in the immediate post-abortion period. Chi-square tests were used to assess associations between categorical variables. Statistically significant variables (p ≤ 0.05) were then further analyzed by logistic regression.ResultsAmong 381 respondents, 42.5% intended to use LARCs in the immediate post-abortion period; 35.2% intended to use intra-uterine devices (IUDs); and 13.9% intended to use implants. Previous use of LARC was a predictor for an intention to use LARCs (odds ratio [OR] = 2.41; 95% confidence interval [CI]: 1.06–5.47). Participants with one or no child had reduced odds for an intention to use LARC (OR = 0.32, 95% CI: 0.15–0.47 and OR = 0.29, 95% CI: 0.13–0.68, respectively). Women with a higher sex frequency (at least once per week) showed increased odds for LARC use (OR = 3.34; 95% CI: 1.03–10.78) and married women were more likely to use LARC than single women (OR = 1.57; 95% CI:1.00–2.47). Women who planned to have another baby within two years were more likely not to use LARCs in the immediate post-abortion period (OR = 0.97; 95% CI: 0.43–2.12). Barriers to the use of LARCs were anxiety relating to impaired future fertility (56.2%), LARCs being harmful to health (45.2%), irregular bleeding (44.3%), risk of IUD failure (41.6%) and lack of awareness with respect to LARCs (36.1%).ConclusionsIntention to use LARCs was predicted by marital status, frequency of sexual activity, number of children, planned timing of next pregnancy, and previous LARC use. Impaired future fertility, being harmful to health, irregular bleeding, risk of complications, and lack of awareness with regards to LARCs were the main barriers in their potential use.

Background Earlier age of menarche has been associated with an increased risk of chronic diseases during adulthood, but whether early menarche has intergenerational effect is not clear. Methods In this population-based cross-sectional study, we recruited children from 26 primary schools using cluster random probability sampling in Shanghai, China, in 2014. We used multiple linear regression models to estimate the adjusted associations of maternal age of menarche (MAM) with offspring body mass index (BMI). We also used the mediation analysis to examine the contribution of maternal BMI and gestational diabetes to offspring BMI. Results A total of 17,571 children aged 6–13 years were enrolled, of whom 16,373 had their weight and height measured. Earlier MAM was associated with higher child BMI in boys (− 0.05 z-score per year older MAM, 95% CI − 0.08 to − 0.02) and in girls (− 0.05 z-score per year older MAM, 95% CI − 0.07 to − 0.02). Maternal BMI positively mediated the association of MAM with offspring BMI in both sexes, with mediation effects of 37.7 and 19.4% for boys and girls, respectively. Conclusion Early maternal menarche was associated with greater offspring BMI. This study provides evidence for the intergenerational effect in the development of BMI in offspring.

Background As the birth policy has been adjusted from one-child-one-couple to universal two-child-one-couple in China, there is an increasing number of women undergoing a second pregnancy after a previous cesarean section (CS). Undertaking an elective repeat CS (ERCS) has been taken for granted and has thus become a major contributor to the increasing CS rate in China. Promoting trial of labor after CS (TOLAC) can reduce the CS rate without compromising delivery outcomes. This study aimed to investigate Chinese obstetricians’ perspectives regarding TOLAC, and the factors associated with their decision-making regarding recommending TOLAC to pregnant women with a history of CS under the two-child policy. Methods A cross-sectional survey was carried out between May and July 2018. Binary logistic regression was used to determine the factors associated with the obstetricians’ intention to recommend TOLAC to pregnant women with a history of CS. The independent variables included sociodemographic factors and perceptions regarding TOLAC (selection criteria for TOLAC, basis underlying the selection criteria for TOLAC, and perceived challenges regarding promoting TOLAC). Results A total of 426 obstetricians were surveyed, with a response rate of ≥83%. The results showed that 31.0% of the obstetricians had no intention to recommend TOLAC to pregnant women with a history of CS. Their decisions were associated with the perceived lack of confidence regarding undergoing TOLAC among pregnant women with a history of CS and their families (odds ratio [OR] = 2.31; 95% CI: 1.38–1.38); obstetricians’ uncertainty about the safety of TOLAC for pregnant women with a history of CS (OR = 0.49; 95% CI: 0.27–0.96), and worries about medical lawsuits due to adverse delivery outcomes (OR = 0.14; 95% CI: 0.07–0.31). The main reported challenges regarding performing TOLAC were lack of clear guidelines for predicting or avoiding the risks associated with TOLAC (83.4%), obstetricians’ uncertainty about the safety of TOLAC for women with a history of CS (81.2%), pregnant women’s unwillingness to accept the risks associated with TOLAC (81.0%) or demand for ERCS (80.7%), and the perceived lack of confidence (77.5%) or understanding (69.7%) regarding undergoing TOLAC among pregnant women and their families. Conclusion A proportion of Chinese obstetricians did not intend to recommend TOLAC to pregnant women with a history of CS. This phenomenon was closely associated with obstetricians’ concerns about TOLAC safety and perceived attitudes of the pregnant women and their families regarding TOLAC. Effective measures are needed to help obstetricians predict and reduce the risks associated with TOLAC, clearly specify the indications for TOLAC, improve labor management, and popularize TOLAC in China. Additionally, public health education on TOLAC is necessary to improve the understanding of TOLAC among pregnant women with a history of CS and their families, and to improve their interactions with their obstetricians regarding shared decision making.
