RESUMEN
BACKGROUND: Gestational diabetes mellitus (GDM) is associated with DNA methylation and lifestyle. The effects of DNA methylation on GDM, and the interaction between DNA methylation and lifestyle factors are not well elucidated. The objective of this study was to explore the association between GDM, DNA methylation and lifestyle factors. METHODS: A nest case-control design was performed. Sociodemographic data, dietary intake and daily physical activity information of pregnant women were collected. Bisulfate pyrosequencing was used to detect the DNA methylation level of PPARGC1A, HLA-DQA1, and ADCY3 genes. The differences of DNA methylation levels between the GDM group and the control group were compared. The correlation between clinical characteristics, dietary, physical activity and DNA methylation level was analyzed. RESULTS: A total of 253 pregnant women were enrolled, of which, 60 participants (GDM: 30; control: 30) were included in the final analysis. There were no significant differences in DNA methylation levels of six methylated sites between the two groups in this study (P > 0.05). Daily intake of potato and poultry were associated with DNA methylation level of the CpG 1 site of the ADCY3 gene in all participants and the control group (P < 0.05). Duration of folic acid intake before pregnancy was correlated with the methylation level of the CpG 1 site of the ADCY3 gene in all participants (r = 0.341, P = 0.04) and the control group (r = 0.431, P = 0.025). Daily oil intake was correlated with the methylation level of CpG 2 (r = 0.627, P = 0.016) and CpG 3 (r = 0.563, P = 0.036) of PPARGC1A in the GDM group. CONCLUSION: The association between the DNA methylation levels and GDM wasn't validated. There were associations between dietary and DNA methylation in pregnant women. A large-sample-sized and longitudinal study is warranted to further investigate the impacts of lifestyle on DNA methylation.

Research on the association between maternal PM2.5 exposure and hypospadias risk in male offspring, particularly in highly polluted areas, has been limited and inconsistent. This study leveraged data from China's National Population-based Birth Defects Surveillance System spanning the years 2013 to 2019, and employed sophisticated machine learning models to estimate daily PM2.5 levels and other pollutants for mothers at a 1-km resolution and a 6-km buffer surrounding maternal residences. Multivariate logistic regression analyses were performed to evaluate the relationship between PM2.5 exposure and hypospadias risk. For sensitivity analyses, stratification analysis was conducted, and models for one-pollutant and two-pollutants, as well as distributed lag nonlinear models, were constructed. Of the 1194,431 boys studied, 1153 cases of hypospadias were identified. A 10 µg/m3 increase in maternal PM2.5 exposure during preconception and the first trimester was associated with an elevated risk of isolated hypospadias, with Odds Ratios (ORs) of 1.102 (95% CI: 1.023-1.188) and 1.089 (95% CI: 1.007-1.177) at the 1-km grid, and 1.122 (95% CI: 1.034-1.218) and 1.143 (95% CI: 1.048-1.246) within the 6-km buffer. Higher quartiles of PM2.5 exposure were associated with increased odds ratios compared to the lowest quartile. These findings highlight a significant association between PM2.5 exposure during the critical conception period and an elevated risk of isolated hypospadias in children, emphasizing the need for targeted interventions to reduce PM2.5 exposure among expectant mothers.

BACKGROUND: Positive development plays an important role in youth when dealing with stressful circumstances. According to the resource dilution theory, adolescents with or without siblings may receive different levels of emotional and material resources from their parents. The purpose of this study is to examine the association between the positive development of adolescents in China today with their family characteristics such as the number of siblings. METHODS: A total of 2072 junior high and senior high school students (13 to 18 years old) in Chengdu, Sichuan, China, were investigated by cluster sampling. The Chinese Positive Youth Development scales (CPYDs) were used to measure positive youth development. The generalized linear model was used to explore the relationships among the number of siblings, parent-child relationships and positive youth development. RESULTS: Adolescents from only-child families had better performance on positive development (H = 21.87, P < 0.001) and better relationships with parents (H = 15.1, P < 0.05). The positive development of male and female adolescents does not significantly differ in families with different numbers of siblings. The generalized linear model showed that a positive parent-child relationship is positively correlated with adolescent positive development (P < 0.05). CONCLUSION: Positive youth development is not only associated with the number of siblings but also other modifiable familial factors. The positive relationship between parents and adolescents is of great practical value in daily life to improve youth development, and this might be the real lesson the resource dilution theory tells.

BACKGROUND: Nutritional status is a modifiable factor associated with perimenopausal women's health and quality of life. Assessing body composition indicators helps to comprehensively understand nutritional status compared with using body mass index (BMI) only. However, few published studies measured the trends in body composition among perimenopausal women. OBJECTIVES: To assess the one-year trajectory of the nutritional status of perimenopausal women and to explore its influential factors. METHODS: A community-based observational study with 3-wave repeated measurements at 6-month intervals was carried out. The nutritional status indicators include weight, body mass index (BMI), and body composition variables. Bioelectrical impedance analysis was used to assess body composition. Repeated measures ANOVA and Chi-square test were used to calculate the changes in nutritional status and generalized estimating equations were performed to explore their influential factors. RESULTS: 2760 participants completed the study. Increasing trajectories in weight (from 56.05 ± 7.55 to 57.02 ± 7.60), fat mass (from 17.99 ± 4.80 to 20.49 ± 4.90), and waist-hip ratio (from 0.86 ± 0.04 to 0.91 ± 0.15) were found (P < 0.001). Decreasing trajectories in skeletal muscle (from 20.30 ± 2.38 to 19.19 ± 2.46), protein level (from 7.39 ± 0.79 to 7.06 ± 0.81), and total body water (from 27.87 ± 2.92 to 27.00 ± 3.01) were found (P < 0.001). Being married/unmarried with a partner and without negative life events were associated with higher total body water, skeletal muscle, and protein level, while negatively associated with fat mass and waist-hip ratio. Age was positively associated with fat mass (P < 0.001). Participants with junior high school education were prone to increased fat mass (P = 0.018) compared with those holding primary school education and below. A per capita monthly income of 1500 to 3000 Yuan was associated with higher total body water, skeletal muscle, and protein level (P < 0.001) compared with a per capita monthly income of less than 1500 Yuan. CONCLUSION: Worsening nutritional status exists in perimenopausal women, which is characterized by increased weight, fat mass, and waist-hip ratio, and decreased skeletal muscle, total body water, and protein level. For greater efficiency, precision nutritional interventions are needed, and recipients should be classified into different risk levels based on their sociodemographic background.

Objective. This study aims to investigate compliance and the influencing factors related to pediatric tuberculosis patients who are undergoing treatment with anti-tuberculosis drugs in the Sichuan Province of China. Methods. A questionnaire survey was conducted between March 2019 and March 2021. The survey was distributed to caregivers of children aged 0 to 14 who had been diagnosed with pulmonary tuberculosis. These children had been receiving oral anti-tuberculosis drug treatment for more than 1 month. The survey was administered at the pediatric infection departments of West China Second University Hospital, Sichuan University, and The First People's Hospital of Ganzi Prefecture. Results. The study revealed a notable lack of medication adherence among the pediatric patients. Through multiple linear regression analysis, it was determined that several factors played a role in influencing medication adherence among children with tuberculosis. These factors include the educational level of the parents, the frequency of daily anti-tuberculosis drug prescriptions, and the parents' comprehension of the disease. All of these factors showed statistically significant influence on medication adherence among pediatric tuberculosis patients (all P < .05). Conclusion. In order to enhance adherence among pediatric patients undergoing anti-tuberculosis treatment, it is imperative to focus on reinforcing health education, particularly for parents with lower educational attainment and limited understanding of the disease.
RESUMEN
Introduction: Women with perinatal anxiety have reduced coping capacity during labor, which affects labor progress and increases the likelihood of a cesarean section. Several non-pharmacological interventions for anxiety during childbirth are available. This study used the "lite touch" method, a non-pharmacological intervention based on physiological responses and obstetric clinical experience in women. We aimed to evaluate whether lite touch could relieve perinatal anxiety and investigate the effect of light skin stroking on the maternal hormones, catecholamine, and cortisol. Methods: This randomized clinical trial involved women with low-risk singleton pregnancies at full term or near term. Eligible pregnant women who were latent and did not undergo epidural anesthesia were randomized into two groups. Participants in the intervention group underwent routine prenatal care, including lite touch, whereas the control group underwent routine prenatal care alone. Demographic data were collected through a questionnaire. Labor anxiety was assessed using the State Anxiety Inventory, and saliva was collected before and after the intervention. Changes in saliva cortisol and catecholamine levels were analyzed using a double-antibody sandwich enzyme-linked immunosorbent assay. Results: In total, 83 participants were included, with 43 and 40 in the intervention and control groups, respectively. In the intervention group, pre-intervention anxiety scores were significantly lower (p < 0.01) than post-intervention anxiety scores, whereas the control group showed no difference in anxiety scores before and after intervention (p > 0.05). Cortisol and catecholamine levels in saliva were significantly lower in the intervention group than in the control group after the intervention (p < 0.01). Discussion: Lite touch can reduce the latent anxiety state of low-risk pregnant women, thereby maintaining in vivo stability and facilitating labor.

RESUMEN
BACKGROUND: The increasing incidence of gestational diabetes mellitus (GDM) is a global health problem that is more likely to occur in pregnant women with overweight or obesity. Adhering to a healthy lifestyle is associated with a reduced risk of GDM. With the development of IT, mobile health (mHealth) interventions have become widely available in health care. However, there are no definitive conclusions on the effectiveness of mHealth-based lifestyle interventions in preventing GDM. OBJECTIVE: This study aims to evaluate the impact of mHealth-based lifestyle interventions on GDM and other pregnancy outcomes in pregnant women with overweight or obesity. METHODS: A systematic literature search was conducted in 5 English databases (MEDLINE, Embase, Web of Science, CENTRAL, and CINAHL) and 4 Chinese databases (CBM, CNKI, Vip, and Wanfang) to identify randomized controlled trials (RCTs) on the effectiveness of mHealth-based interventions for GDM from inception to January 10, 2023. In total, 2 authors independently screened the studies and extracted the data. The quality of the included studies was examined using the Cochrane risk-of-bias tool. Data synthesis was conducted using Review Manager (version 5.4; The Cochrane Collaboration). RESULTS: A total of 16 RCTs with 7351 participants were included in this study. The included studies were published between 2014 and 2021 and were conducted in China, the United States, Australia, New Zealand, the United Kingdom, Ireland, and Norway. The sample sizes of the studies ranged from 75 to 2202, and the duration of the mHealth-based lifestyle interventions ranged from 4 to 28 weeks. Compared with usual care, mHealth-based lifestyle interventions significantly reduced the incidence of GDM (odds ratio [OR] 0.74, 95% CI 0.56-0.96; P=.03; I2=65%), preterm birth (OR 0.65, 95% CI 0.48-0.87; P=.004; I2=25%), macrosomia (OR 0.59, 95% CI 0.40-0.87; P=.008; I2=59%), and gestational weight gain (mean difference=-1.12 kg, 95% CI -1.44 to -0.80; P<.001; I2=43%). The subgroup analysis showed that interventions delivered via apps (OR 0.55, 95% CI 0.37-0.83; P=.004; I2=44%), provided by obstetricians (OR 0.69, 95% CI 0.51-0.93; P=.02; I2=60%), and targeted at Asian populations (OR 0.44, 95% CI 0.34-0.58; P<.001; I2=0%) and that used the International Association of Diabetes and Pregnancy Study Groups diagnostic criteria (OR 0.58, 95% CI 0.39-0.86; P=.007; I2=69%) showed a statistically significant reduction in the risk of GDM. CONCLUSIONS: mHealth-based lifestyle interventions had a favorable impact on the prevention of GDM in pregnant women with overweight and obesity. Future studies need to further explore the potential of mHealth-based interventions for GDM through better design and more rigorous large-scale RCTs.

OBJECTIVES: To explore the use of complementary and alternative medicine (CAM) by Chinese gynaecological oncology patients undergoing chemotherapy and discuss measures to address the existing gaps. DESIGN: Qualitative phenomenology. Semistructured in-depth interview. Colaizzi's method data analysis. SETTING: A tertiary general hospital. PARTICIPANTS: 16 gynaecological oncology patients (mean age 51.7) having undergone ≥1 chemotherapy cycle were recruited by purposive sampling. RESULTS: Six themes were generated. The participants were under-informed about CAM concept and options. They were open to explore various modalities after chemotherapy as long as it could alleviate symptoms. The gynaecological patients with cancer sought information about CAM from diverse sources, with professional expertise being the most desirable way to seek information. They used CAM as a strategy to support continued chemotherapy and for symptom alleviation. Financial burden was not stressed but they had concerns about sustainability of some therapies. Their attitudes toward different CAM types varied. Some were sceptical about the efficacy. CONCLUSIONS: The Chinese gynaecological oncology patients may be under-informed about CAM. They are open to use various CAM therapies for symptom relief and as a support strategy. However, their attitudes toward specific therapies may vary. Some may host scepticism about certain CAM modalities. The patients actively seek information on CAM and treatment resources but prefer professional expertise to other sources. Financial burden due to continued CAM use is inconclusive due to possible sampling bias. Sustainability of CAM therapies is a common concern because of limited resources and access. Education on CAM should be incorporated into the curriculum of healthcare professionals. Oncologists and nurses should educate gynaecological patients with cancer on the concept and options of CAM, preferably with information tailored to patient's individual needs. Health authorities should advocate provisions of diverse CAM services and develop the necessary technologies such as network of local care resources.

OBJECTIVES: The objective was to assess the prevalence of perinatal depressive symptoms and determine the trajectories of marital adjustment and depressive symptoms and their reciprocal relationships among Chinese perinatal women. DESIGN: This was a prospective, longitudinal cross-lagged study. SETTING: The study was conducted at the outpatient department of the largest women's and children's hospital in China, which is located in Chengdu, Sichuan Province. PARTICIPANTS: Four hundred and sixty-three mothers were conveniently sampled. MAIN OUTCOME MEASURES: The Dyadic Adjustment Scale and the Chinese version of the Edinburgh Postnatal Depression Scale were used to evaluate marital adjustment and depressive symptoms, respectively, at three time points: the first trimester of pregnancy (T1), the third trimester of pregnancy (T2) and 6 weeks after childbirth (T3). Descriptive statistics were used to assess the prevalence of perinatal depressive symptoms, and repeated-measures analysis of variance (ANOVA) was used to determine the trajectories of marital adjustment and depressive symptoms among the participants. A cross-lagged model was used to explore the reciprocal relationship between marital adjustment and depressive symptoms. RESULTS: The prevalence of perinatal depressive symptoms among our participants ranged from 21.2% to 24.0%. Repeated-measures ANOVA showed that during the perinatal period there was a significant tendency towards worse marital adjustment (F=33.031, p=0.000) and a slight but not significant reduction in depressive symptoms (F=1.883, p=0.153) among the participants. The cross-lagged model showed that maternal marital adjustment at T1 significantly and negatively predicted depressive symptoms at T2 (ß=-0.165, p<0.001), and that depressive symptoms at T2 significantly and negatively predicted marital adjustment at T3 (ß=-0.135, p<0.001). However, the predictive effects of depressive symptoms at T1 on marital adjustment at T2 and that of marital adjustment at T2 on depressive symptoms at T3 were not significant. CONCLUSION: The prevalence of perinatal depressive symptoms ranged from 21.2% to 24.0% among the participants. During the perinatal period, the marital adjustment of women tended to be worse; however, there was no significant change in depressive symptoms. This study showed that better marital adjustment at T1 was a protective factor against maternal depressive symptoms at T2, and a higher level of depressive symptoms at T2 was a risk factor for worse marital adjustment at T3.

(1) Background: Female body composition undergoes significant changes to support fetal growth and development during pregnancy. This study investigated the association of maternal body composition in the second trimester and macrosomia and explored whether body-composition-related indicators could be used to predict macrosomia. (2) Methods: This study was conducted in China from December 2016 to December 2021. Women with singleton pregnancies, gestational ages between 37 and 42 weeks, and an absence of pregnancy complications were included. In the second trimester, bioelectric impedance analysis (BIA) was used to measure body-composition-related indicators. Logistic regression analysis was performed to explore the risk factors for macrosomia. The predictive performance of maternal body composition and clinical indicators for macrosomia were assessed using the area under the receiver-operating-characteristics curve (AUC). (3) Results: This retrospective study involved 43,020 pregnant women; we collected 2008 cases of macrosomia. Gravidity, gestational age, body mass index (BMI), gestational weight gain (GWG), total body water, fat mass, fat-free mass (FFM), skeletal muscle mass, and visceral fat level were risk factors for macrosomia (p < 0.05 for all). In the prediction model, the AUC of FFM for predicting macrosomia was the largest (0.742). (4) Conclusions: Body-composition-related indicators associated with macrosomia and body composition measurements in the second trimester can predict the risk of macrosomia, enabling clinicians to implement interventions earlier to reduce adverse perinatal outcomes.

INTRODUCTION: Problematic Internet use (PIU), which is associated with deliberate self-harm (DSH), has become a common problem among adolescents. Life satisfaction (LS) may be able to mitigate the negative influences of PIU and DSH. But the longitudinal associations among them are yet to be well-researched. METHODS: A longitudinal study with three-wave data collection involving 6092 adolescents was carried out in China. PIU, LS, and DSH were assessed using the Young Internet Addiction Test, the Satisfaction with Life Scale, and the Deliberate Self-Harm Inventory Nine-Item Version, respectively. A cross-lagged model was used to analyze the longitudinal interactions between them. Generalized Estimating Equations were adopted to identify their influential factors. RESULTS: The prevalence of single DSH behaviors from wave 1 to wave 3 was 5.04%, 5.00%, and 4.67%, and the repeated DHS from wave 1 to wave 3 was 2.9%, 3.2%, and 3.4%, respectively. Bidirectional longitudinal predictive associations were revealed between PIU and LS (pï¼0.001), and LS and DSH (pï¼0.001). DSH could longitudinally predict PIU (pï¼0.001). Gender and age were associated with PIU, LS, and DSH (pï¼0.001), and PIU was influenced by ethnicity (pï¼0.001). CONCLUSION: PIU and LS, LS and DSH were associated bidirectionally. Adolescents with more severe DSH behaviors were inclined to become addicted to the Internet, and adolescents with a history of DSH had a higher risk of recurring DSH. Parents, schools, and administrators need to improve the LS of adolescents, with a particular focus on older, female adolescents.

Background: COVID-19 has become a global pandemic, which necessitates that health workers be capable of protecting themselves and their patients. This article aimed to describe knowledge levels, attitudes, behaviors and training needs regarding COVID-19 among obstetric and gynecological nurses in medium-risk areas during the pandemic. Method: A cross-sectional survey of obstetric and gynecological nurses in medium-risk areas was performed during the peak period of the pandemic in China. The main survey tool was the self-designed COVID-19 Knowledge, Attitude, Behavior and Training Needs Questionnaire. Pearson correlation analysis was conducted to analyze the relationships among knowledge, attitudes, behaviors and training needs. Results: A total of 599 nurses were recruited, of whom 27.7% failed the knowledge part of the questionnaire. Positive correlations were found between knowledge and attitudes (r = 0.100, P = 0.015) and between attitudes and behaviors (r = 0.352, P = 0.000) regarding occupational protection against COVID-19. A total of 88.5% of nurses preferred online training to traditional training, and more than 70% believed that demonstration of and training in operations by their own department were effective ways to learn about how to protect themselves against COVID-19. Conclusion: The higher the level of knowledge about the disease was, the more positive the attitude toward occupational protection, and consequently, the more actively protective behaviors were adopted. Training affected nurses' knowledge of COVID-19 occupational protection and promoted positive attitudes, which further facilitated the effective prevention and control of the disease. Online training with demonstrations are recommended for COVID-19 training of nurses.
RESUMEN
Findings of prior studies about the efficacy and safety of non-vitamin K antagonist oral anticoagulants (NOACs) in patients (≥80 years of age) with atrial fibrillation (AF) are controversial. So we performed a meta-analysis to evaluate the efficacy and safety of NOACs versus vitamin K antagonists (VKAs) in patients (≥80 years of age) with AF. A systematic review of PubMed, Cochrane, Embase, Web of Science and Chinese BioMedical databases was conducted until 1 October 2022. Studies reporting the effects and safety of NOACs versus warfarin in patients (≥80 years of age) with AF were included. Two authors independently performed study selection and data extraction. Discrepancies were resolved by consensus or through an independent third reviewer. Data were synthesised according to the Preferred Reporting Items for Systematic Reviews guidelines. We identified 15 studies providing data of 70 446 participants (≥80 years of age) suffering from AF. According to the meta-analysis (odds ratio (OR) (95% confidence interval, CI)), NOACs conferred better efficacy profile than VKAs in stroke and systemic embolism (0.8 (0.73-0.88)) and all-cause mortality (0.61 (0.57-0.65)). Otherwise, NOACs conferred a better safety profile than VKAs in major bleeding (0.76 (0.70-0.83)) and intracranial haemorrhage (ICH; 0.57 (0.47-0.68)). In conclusion, for patients (≥80 years of age) with AF, the risks of stroke and systemic embolism, all-cause mortality, were lower in NOACs compared to warfarin. The risks of major bleeding and ICH were also lower in NOACs compared to warfarin. NOACs showed better efficacy and safety than warfarin.

Background: Fluid overload remains a vexing problem in management of heart failure. The lymphatic system that plays the central role in fluid homeostasis has recently been explored as a potential target to counteract tissue fluid overload. The goal of the study was to evaluate the preliminary effects of exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions for patients with heart failure. Methods and results: A pilot, pre- and post-test, randomized clinical trial was conducted to recruit a total of 66 patients who were randomized to receive either a 4-week The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF) program or usual care alone. The primary outcome was the prevalence and burden of the fluid overload symptoms. Findings of the trial showed that the TOLF-HF intervention was effective in reducing the prevalence or burden of the majority of fluid overload symptoms. TOLF-HF intervention also demonstrated significant improvement in the outcomes of abnormal weight gains (MD: -0.82; 95% CI: -1.43 to -0.21; P = 0.010) and physical functions (F = 13.792, P < 0.001). Conclusions: The TOLF-HF program focusing on activating lymphatic system through the performance of therapeutic lymphatic exercises holds the promise as an adjuvant therapy for patients with heart failure to manage fluid overload symptoms, reduce abnormal weight gains, and improve physical functions. Future larger-scale study with longer duration of follow-up is needed. Clinical Trial Registration: http://www.chictr.org.cn/index.aspx, identifier ChiCTR2000039121.
RESUMEN
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 (ß = 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 (ß = 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.

The objectives of this study were to assess the trends in anxiety and depression levels in older adults nearly 10 months after the outbreak of coronavirus disease 2019 (COVID-19) and explore its determinants. A longitudinal study was performed between October 2019 and December 2020. The Patient Health Questionnaire 9-Item Scale and the Generalized Anxiety Disorder 7-Item Scale were used to assess depression and anxiety. Data were collected before (wave 1), during (wave 2), and 10 months after the COVID-19 outbreak (wave 3). The prevalence of depressive symptoms in the elderly was found to be 18.9%, 28.1%, and 35.9% at wave 1, wave 2, and wave 3 respectively. The prevalence of depressive symptoms at wave 1 was lower than that at wave 2 (χ 2 = 15.544, P < 0.001) and wave 3 (χ 2 = 44.878, P < 0.001). There was no significant change in the prevalence of anxious symptoms (wave 1, 28.5%, wave 2, 30.3%, and wave 3, 30.3%). Older adults who were single/divorced/widowed had higher levels of anxiety compared with those who were married (OR = 2.306 95%CI 1.358-3.914, P = 0.002). The pandemic appeared to be associated with increases in depressive symptoms in older persons. Targeted interventions could be carried out among those with higher risk of maladjustment.
RESUMEN
INTRODUCTION: Although 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 ANALYSIS: This 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 DISSEMINATION: Ethical 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.

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.

COVID-19-related lockdown measures have been affecting children's weight status and weight-related behaviors, which are often associated with an increase in childhood obesity. However, large-scale longitudinal studies are lacking. Our study aimed to analyze changes in obesity and weight-related behaviors in Chinese children before and during the COVID-19 pandemic and provide references for addressing the high prevalence of childhood obesity. A prospective multi-center longitudinal survey was conducted among Chinese children (n = 5963), collecting data on weight status, COVID-19-related measures, and lifestyle behaviors. Changes were assessed using t-tests and χ2 tests for paired samples, or the Wilcoxon signed-rank test, according to the type and distribution of data. The Generalized Estimating Equations model was used to explore influential factors of obesity. The prevalence of overweight and obesity increased from 9.2% and 8.6% before the pandemic to 10.5% and 10.6% during the pandemic (p < 0.001), respectively. Daily physical activity, sleep duration, and sugar-sweetened beverage consumption decreased while screen time increased. The results of the generalized estimating equations showed that ethnic minority, older age, less daily physical activity, reduced sleep duration, and longer screen time were positively associated with obesity. There is an intensifying trend of obesity in children in the context of the COVID-19 pandemic, to which altered weight-related behaviors might have contributed largely. Maintaining a healthy lifestyle, especially in social crises, should be highlighted to ease the burden of childhood obesity.

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.
