In rural China, there is an urgent need for investment and innovative approaches for addressing adolescent mental health issues. This embedded mixed-methods study examines the effectiveness of a social-emotional learning (SEL) program in rural primary schools across China and the factors affecting compliance among teachers delivering the program. Pre- and post-intervention surveys assessed its effect on 2027 students in 49 schools, and 38 teachers were interviewed during the intervention. Results show that SEL courses improved student mental health. Some teachers reported increased workload and lack of support, while others noted the importance of mental health education and positive student outcomes. Performance incentives and the positive perceptions of SEL among teachers were crucial for effective delivery, though workload and lack of support often limited commitment. Overall, enhancing rural students' well-being through SEL programs requires raising awareness for SEL among teachers and building institutional support.

Objectives
Considering the importance of caregiver mental health for early childhood development, this study investigates risk and protective factors of mental health of mothers and grandmothers caring for infants and toddlers in rural China.

Methods
Using survey data from 777 primary caregivers of children aged 5 to 25 months, we apply regression analysis and structural equation modeling to examine associations between social support, mental health literacy, parenting-related hardships, and mental health among mothers and grandmothers.

Results
The study finds that 33% of the caregivers report symptoms of mental health problems, with grandmothers experiencing more severe symptoms. Poor caregiver mental health is associated with lower child language (p < 0.05) and social-emotional development (p < 0.001). Social support and mental health literacy are associated with better mental health, but this association was not statistically significant among either the mothers or the grandmothers alone.

Conclusions
Enhancing caregiver mental health is crucial for children’s development. Social support and mental health literacy are predictors of mental health. Future research should examine the effect of improving social support and mental health literacy on the mental health of caregivers for young children.

Introduction: Longitudinal trends in breastfeeding (BF) are often overlooked in favor of binary or time-to-cessation measures. Characterizing these trends can inform promotion of sustained BF practices. We identified distinct BF profiles among participants of a maternal and child health program.

Methods: The Healthy Future program consisted of community health workers delivering a BF curriculum to mothers through monthly home visits. The program was evaluated in rural Sichuan, China with a cluster-randomized controlled trial (assigned to program versus not). We clustered 6-month postpartum trends (n = 949) of maternal-reported infant feeding using dynamic time warping. For each month, participants were categorized as either exclusive breastfeeding (EBF), mixed feeding (MF, feeding breastmilk plus other foods or liquids), or not breastfeeding (NBF). After identifying clusters, we regressed BF profiles on intervention assignment using adjusted multinomial logistic regression.

Results: Cluster analysis revealed seven profiles: always EBF, always MF, never breastfed, EBF until the 5th month, MF until the 5th month, mostly EBF, and NBF from the 3rd month. The intervention was associated with improved odds of always EBF (ROR = 2.61, 95% CI 1.25, 5.42), MF until the 5th month (ROR = 2.52, 95% CI 1.18, 5.39), and NBF from the 3rd month (ROR = 2.82, 95% CI 1.16, 6.87) compared to being never breastfed. Mothers in the never breastfed cluster had the lowest age, education, BF knowledge and attitudes, and decision-making power.

Discussion: Cluster analyses found the intervention significantly improved EBF, particularly in mothers characterized by higher baseline educational attainment and BF knowledge. Targeted efforts are needed to help mothers initiate EBF from birth and continue EBF through month 6.

The connections between bullying and student well-being in rural areas are not well understood, particularly among younger, more vulnerable students. This study aims to explore the relationship between bullying experiences and the academic performance and mental health of primary and junior high school students in rural China. The sample comprised 1609 students from 30 schools (20 primary schools and 10 junior high schools) in Gansu province. A self-report questionnaire was used to collect data on students’ demographics, bullying experiences, mental health, and social support. Additionally, a 30-minute standardized math test was administered to assess academic performance. Results indicated that bullying was prevalent in rural settings, with 42.64% of students reporting being bullied and 12.74% experiencing it weekly. A significant correlation was found between bullying experiences and both lower academic performance and higher risk of mental health problems, such as depression and anxiety. These correlations became more pronounced with increased frequency of bullying incidents. We also found that female students and younger students who were bullied were more likely to report mental health issues. Furthermore, social support could diminish, but not entirely counteract, the adverse associations between bullying and mental health. These findings highlight the prevalence of bullying among rural students in this age group and demonstrate the associated negative outcomes for their mental health and academic performance. They also emphasize the need for targeted attention and the development of intervention programs, including enhanced school-based anti-bullying initiatives and improved social support systems.

Background
Under-resourced communities in rural China have long faced limitations in accessing and utilising caregiver and child healthcare (CCH). The COVID-19 pandemic exacerbated health inequities globally, while its precise impacts on CCH remain understudied. We report differences in parental migration, maternal mental health, household and nutrition expenditures, child feeding practices, and prenatal, postnatal, and childbirth care following pandemic lockdowns in rural China.

Methods
We compared two groups of families with children who grew to the age of six months either before or during lockdowns. We enrolled eligible households from 80 rural townships, randomly selected from four poverty-designated counties in Sichuan Province, China. We interviewed the control group of primary caregivers in November and December of 2019 (pre-COVID-19), and the case group in May of 2020 (approximately five months into the pandemic). Statistical analyses included t tests and linear regressions with adjustments. P-values <0.05 were considered statistically significant.

Results
Compared to the control group, the case group presented significantly lower paternal migration and more favourable maternal mental health. Caregiving behaviours (including household and nutrition expenditures) and child feeding practices did not differ, except for higher spending on infant micronutrient supplements. Prenatal health services utilisation, including home visits, was slightly higher, while postnatal services utilisation was lower.

Conclusions
Our findings suggest that many aspects of CCH in rural China were similar or improved during the early pandemic lockdowns. These data highlight the importance of promoting targeted public health interventions, such as mental health support initiatives, accessible perinatal care options, and family-centred education campaigns, in under-resourced communities and during future healthcare crises.

Background
Mindfulness-based interventions (MI) have shown efficacy in improving mental health among adults; however, the results for younger populations remain inconsistent Research on this topic in low- and middle-income countries is still limited. This study seeks to address this gap by examining the impact of a mindfulness-based intervention on Chinese migrant youth.

Methods
A randomized controlled trial delivering mindfulness and life skills mentorship to 653 migrant students aged 9 to 17 in China. Quantitative results in depression and anxiety were examined between Mindfulness Training group (MT group, n = 167), the Mindfulness Training plus Life Skill Training group (MT + LS group, n = 118), and Control group (n = 368) using student t-tests and Differences-in-Differences. Qualitative study from 20 interviews was conducted using a semi-structured interview and deductive approach.

Results
Quantitatively, participants in intervention group did not show significantly different anxiety and depression symptoms compared to control groups post intervention. Nevertheless, qualitative data highlighted several key benefits of the mindfulness intervention, including improved emotional regulation and increased social support among participants.

Conclusions
A volunteer-led, two-month mindfulness and life skills intervention with Chinese migrant youth did not yield statistically significant reduction in depression or anxiety symptoms. While no notable quantitative benefits were observed, qualitative findings suggested enhanced application of mindfulness and emotional regulation skills among participants that the quantitative measures failed to capture.
