Background Breastfeeding and maternal health play crucial roles in improving newborn health, which is closely related to the development of families and society. Early essential newborn care, which emphasizes early exclusive breastfeeding and skin-to-skin contact, is recommended by the World Health Organization. This study aimed to explore the association of early essential newborn care with breastfeeding and maternal outcomes. Methods A nonrandomized controlled study was carried out from May 2020 to January 2021 in a tertiary hospital in Chengdu city, China. Pregnant women were recruited from the maternity ward before they gave birth. Early essential newborn care was performed for 91 mother-newborn pairs after birth in the intervention group, while routine birth care was performed for 91 mother-newborn pairs in the control group. Data on breastfeeding and maternal outcomes were collected pre-test and post-test and were recorded by trained data collectors and retrieved from hospital case record files. Results Compared with the control group, the intervention group had a higher incidence of early breastfeeding initiation, an earlier initiation and longer duration for the first breastfeeding, a higher incidence of successful first breastfeeding, more exclusive breastfeeding at hospital discharge, higher maternal breastfeeding self-efficacy, a shorter duration of the third stage of labour, lower postpartum blood loss, and lower scores of maternal pain and anxiety postpartum; the differences were statistically significant (p < 0.05). Conclusion The implementation of high-quality early essential newborn care can help mothers initiate early breastfeeding, improve exclusive breastfeeding rates at hospital discharge, enhance breastfeeding self-efficacy, promote the woman’s recovery from labour, and reduce maternal anxiety and pain in the postpartum period. High-quality early essential newborn care is recommended to policymakers and medical professionals to improve breastfeeding and maternal outcomes.

The World Health Organization recommended that the oral intake of low-risk pregnant women during labor should not be restricted. Hospitals in different countries take different measures to manage the intake during labor, but it is not clear about the current situation of oral intake management measures in the hospital during labor in China. Thus, the objective of this study was to investigate the current situation of oral intake management measures during labor in China, so as not only provide references for developing appropriate midwifery technology training and formulating relevant policies, but also provide a basis for exploring and implementing better oral intake management measures in the future. A cross-sectional survey was conducted. From December 2017 to November 2018, the oral intake management measures of 1213 hospitals in 22 provinces, cities, and autonomous regions in China were investigated by a self-designed questionnaire. χ 2 test was used for statistical analysis. Different hospitals in China have adopted different oral intake management measures. Among the 1213 hospitals, 939(77.4%) hospitals took measures to allow pregnant women to bring the easily digestible food, 813(67.0%) hospitals took measures to allow pregnant women to eat what she wanted to eat. Few hospitals provide pregnant women with oral nutrition solution or provide a suitable diet for pregnant women. Thirty-four (2.8%) hospitals still restrict pregnant women's fluid intake. Oral intake management measures that are more suitable for Chinese pregnant women should be explored to better ensure the women energy needs and they safely go through childbirth.

Background Adolescence is a formative period of social development. Adolescents have experienced considerable changes in their lives due to the COVID-19 pandemic. We conducted a longitudinal study to examine the effects of the COVID-19 pandemic on adolescents’ prosocial attributes and empathy, as well as their longitudinal bilateral relationships. Methods A total of 2,510 students from five junior schools in Sichuan Province were recruited via random cluster sampling. Data were collected in December 2019 (Wave 1, before the outbreak of the pandemic) and July 2020 (Wave 2, during the pandemic) in Chengdu, Sichuan, China. Prosocial attributes and empathy were measured with the Positive Youth Development Scale (GPYDS) subscale and Chinese Empathy Scale, respectively. Results During the pandemic, both empathy and prosocial attributes decreased significantly from 49.89 (9.12) and 49.89 (8.80) before to 48.29 (8.72) and 49.39 (9.26) (p < 0.001), respectively. A higher level of empathy at Wave 1 significantly predicted higher prosocial attributes at Wave 2 (β = 0.173, SE = 0.021, t = 8.430, p < 0.001). A lower prosocial attributes score predicted a significantly lower empathy score from Wave 1 to Wave 2 (β = 0.100, SE = 0.021, t = 4,884, p < 0.001). Conclusions The COVID-19 pandemic has had detrimental effects on adolescents’ empathy and prosocial attributes. Special attention should be given to these two longitudinally associated factors in any social crisis, such as the COVID-19 pandemic, considering their importance for adolescents’ physical, mental, and social development.

Background Women in perimenopause are vulnerable to depressive symptoms, and physical activity was reported to be a potential protective factor. The trajectories of physical activity and depressive symptoms over time and their longitudinal relationships in Chinese perimenopausal women have not been explored yet, leaving a research gap hindering us from better understanding and managing perimenopause depressive symptoms. Methods A multi-center prospective longitudinal study was conducted in four cities in Sichuan Province, China. Depressive symptoms and physical activity in perimenopausal women were collected in March 2019, June 2019, September 2019, and December 2019, respectively. Multivariable linear regression by generalized estimation equation was used to identify the relevant factors associated with depressive symptoms and physical activity. A four-wave autoregressive and cross-lagged panel model was performed to explore their longitudinal relationships. Results A total of 1875 women who completed the four-wave data collection were included in the data analysis. Depressive symptoms exacerbated over time and were associated with women’s age, monthly income, marital status, chronic disease, and negative life events. Physical activity decreased over time and was associated with educational background and monthly income. According to the cross-lagged panel model, perimenopausal women with more severe depressive symptoms tended to be less physically active, and similarly, perimenopausal women with less physical activity were more prone to report more severe depressive symptoms. Conclusion The cross-lagged panel model disclosed longitudinal bidirectional relationships between depressive symptoms and physical activity in perimenopausal women. Appropriate physical activity should be recommended for perimenopausal women to improve their mental well-being. Tailored physical activity duration and maintenance measures should be proposed based on different sociodemographic statuses.

Background Early essential newborn care (EENC) was introduced to medical practice in China in 2016, but the number of medical institutions that have put EENC into practice remains low due to insufficient clinical evidence and the absence of awareness among health professionals. This study aimed to explore the effect of EENC on physiological variables and sleep state among newborn infants and to provide evidence to support the implementation of EENC. Methods A quasi-experimental design was conducted among 182 newborn infants in a tertiary maternity hospital in China from May 2020 to January 2021. A total of 91 newborn infants were included in the intervention group, and 91 were included in the control group to receive EENC or routine birth care, respectively. Results The newborn infants in the intervention group had a lower incidence of hypothermia than those in the control group at 75 min, 90 min, 105 min, and 120 min after birth (p < 0.05). The time of first breathing after birth in the intervention group was earlier than that in the control group (5 s vs. 7 s, p < 0.05), and the infants had a better sleep state at 30 min, 60 min, 90 min, and 120 min after birth (p < 0.05). Conclusions EENC can decrease the incidence of hypothermia, promote the initiation of breathing, and improve the sleep state among newborn infants compared to routine birth care in China. More coaching should be provided to health professionals to promote the implementation of EENC in China.

IntroductionAlthough intrapartum caesarean delivery can resolve dystocia, it would still lead to several adverse outcomes for mothers and children. The obstetric care professionals need effective tools that can help them to identify the possibility and risk factors of intrapartum caesarean delivery, and further implement interventions to avoid unnecessary caesarean birth. This study aims to develop a prediction model for intrapartum caesarean delivery with real-life data based on the artificial neural networks approach.Methods and analysisThis study is a prospective nested case–control design. Pregnant women who plan to deliver vaginally will be recruited in a tertiary hospital in Southwest China from March 2022 to March 2024. The clinical data of prelabour, intrapartum period and psychosocial information will be collected. The case group will be the women who finally have a baby with intrapartum caesarean deliveries, and the control group will be those who deliver a baby vaginally. An artificial neural networks approach with the backpropagation algorithm multilayer perceptron topology will be performed to construct the prediction model.Ethics and disseminationEthical approval for data collection was granted by the Ethics Committee of West China Second University Hospital, Sichuan University, and the ethical number is 2021 (204). Written informed consent will be obtained from all participants and they can withdraw from the study at any time. The results of this study will be published in peer-review journal.
