Children who are under the age of five in underdeveloped and developing countries, including China, exhibit developmental delays due to their exposure to risks such as impoverishment, deprived health conditions, parental punishment, neglect, and poor psychosocial stimulation. Adverse experiences during the formative years of life, such as harsh parental discipline, may put them at risk for poor physical and mental well-being. The aim of this research is to explore the pervasiveness and developmental outcomes of different forms of discipline practices in the underdeveloped rural areas of China. To do this, we used cross-sectional data on child–caregiver dyads from a large survey held in 22 poor counties in the QinBa Mountain Region. The sample included 1622 children aged 12–36 months. Partakers were requested to respond to a general survey on parenting which included basic demographic questions, the Ages and Stages Questionnaire: Social-Emotional (ASQ-SE), the Bayley Scales of Infant and Toddler Development (BSID-III), and questions on exposure of children to different discipline practices. Our findings from OLS estimates reveal that aversive discipline methods adversely affect cognitive, language, and socio-emotional development, whereas, non-aversive discipline practices have constructive effects on cognitive, language, and motor development of children.

Background: The content of children’s screen exposure and interactive coviewing with caregivers are important determinants of early childhood development (ECD) that have been overlooked in past research in resource-limited rural regions. Given the prevalence of digital devices and diverse digital content today, determining screen use practices that minimize the negative impacts on children’s development is crucial for promoting healthy screen use among children. Objective: This study aims to examine screen exposure among children aged 15 minutes on a daily basis had fewer social-emotional or behavioral problems than those with no screen exposure and a lower risk of delay in motor skills development than those exposed to educational content for <15 minutes on a daily basis. Caregiver interaction during screen exposure was associated with a lower risk of cognitive and language delays and better socioemotional skills. Conclusions: The type of content viewed and how caregivers engaged in children’s screen time were strongly associated with ECD outcomes. Guiding parents to select educational content for their children and engaging in interactive coviewing may better protect children from the negative effects of screen exposure. The findings complement conclusions regarding the impact of screen exposure on ECD in resource-limited rural areas.

Background: The first three years of life are the critical and sensitive periods for the formation of individual abilities. However, existing data indicates that early childhood development (ECD) in economically vulnerable areas of China is lagging, which is closely related to the lack of parenting knowledge and poor parenting practices. Methods: We conducted a non-masked cluster-randomized controlled trial in a former nationally designated poverty county of China. All 6–36-month-old children and their caregivers living in 18 communities/clusters (10 towns and 8 districts of the county seat) were enrolled in a 9-month parenting training program. In the treatment-group communities, ECD centers were installed where community workers provided parenting training sessions. If caregivers were unable to visit the center, home-based parenting training was offered. No intervention was provided to the control group. Furthermore, we assigned half of the treatment group to receive monthly developmental feedback in addition to the parenting training. Based on the baseline and follow-up data, we investigated the treatment effects on parenting knowledge, attitudes, and practices through Intention-to-Treat (ITT) and Treatment-on-the-Treated (TOT) analyses. Results: We found no effects on the parenting knowledge and attitudes of the caregivers but significant effects on the parenting practices. The effects were heterogeneous among families with different characteristics. Specifically, on average, the program had the largest effect on internally oriented caregivers, mothers with higher education, and mothers who are primary caregivers. We want to emphasize that, although the ITT effect on parenting practices (the average treatment effect) were stronger for mothers with higher education, the TOT effect on parenting practices (the local average treatment effect, LATE) were stronger for mothers with less education. That is, even though on average the program helped mothers with higher education, but among complier families, the program benefited mothers with less education. Conclusion: The findings indicate that, at least in the short run, the program can directly change caregivers’ parenting practices without changing their knowledge and attitudes. Future studies are needed to investigate whether parenting knowledge and attitudes can change in the long run.

Introduction Alcohol consumption is the seventh leading risk factor for disability-adjusted life years in the world, according to the Global Burden of Disease Study 2017. As the largest developing country, China has a substantial population of alcohol consumers who suffer from related health risks. Despite having made significant advancements in eradicating absolute poverty, many people still live in relative poverty, which suggests that the adverse health effects caused by alcohol consumption among vulnerable populations in China warrant more attention. This paper aims to provide an overview of alcohol consumption among ethnic populations in China and test the feasibility and efficacy of a brief advice intervention with a small financial incentive in reducing harmful drinking behaviours. Methods This study is a three-arm, single-blinded, pragmatic, individually randomised controlled trial with follow-ups at 1,2 and 3 months after randomisation. A total of 440 daily drinkers living in Xichang will be recruited and divided into three groups: brief intervention group, financial incentive group and control group. All participants will receive a urine ethyl glucuronide (EtG) test, which detects alcohol consumption in the past 80 hours. Additionally, participants in the brief intervention group will receive three free counselling sessions alongside multimedia messages on the topic of alcohol consumption after each session. The participants in the financial incentive group will receive the same interventions as well as cash incentives according to the results of the EtG test. The primary outcomes are the self-reported drinking quantity, binge drinking frequency, drinking intensity and the proportion of participants who pass the EtG test. Ethics and dissemination This protocol was approved by the Peking University Health Science Center Institutional Review Board (IRB00001052-20049). Findings will be published in peer-reviewed journals and presented at local, national and international conferences to publicise and explain the research to key audiences. Trial registration number NCT04999371.

Introduction: The high incidences of both the developmental delay among young children and the mental health problems of their caregivers are major threats to public health in low-income and middle-income countries. Parental training interventions during early childhood have been shown to benefit early development, yet evidence on strategies to promote caregiver mental health remains limited. In addition, evidence on the optimal design of scalable interventions that integrate early child development and maternal mental health components is scarce. Methods and analysis: We design a single-blind, factorial, cluster-randomised controlled, superiority trial that will be delivered and supervised by local agents of the All China Women’s Federation (ACWF), the nationwide, government-sponsored social protection organisation that aims to safeguard the rights and interests of women and children. We randomise 125 villages in rural China into four arms: (1) a parenting stimulation arm; (2) a caregiver mental health arm; (3) a combined parenting stimulation and caregiver mental health arm and (4) a pure control arm. Caregivers and their children (aged 6–24 months at the time of baseline data collection) are selected and invited to participate in the 12-month-long study. The parenting stimulation intervention consists of weekly, one-on-one training sessions that follow a loose adaptation of the Reach Up and Learn curriculum. The caregiver mental health intervention is comprised of fortnightly group activities based on an adaptation of the Thinking Healthy curriculum from the WHO. Primary outcomes include measures of child development and caregiver mental health. Secondary outcomes include a comprehensive set of physical, psychological and behavioural outcomes. This protocol describes the design and evaluation plan for this programme. Ethics and dissemination: This study received approval from the Institutional Review Board of Stanford University (IRB Protocol #63680) and the Institutional Review Board of the Southwestern University of Finance and Economics in Chengdu, Sichuan, China. Informed oral consent will be obtained from all caregivers for their own and their child’s participation in the study. The full protocol will be publicly available in an open-access format. The study findings will be published in economics, medical and public health journals, as well as Chinese or English policy briefs. Trial registration number: AEA RCT Registry (AEARCTR-0010078) and ISRCTN registry ( ISRCTN84864201 ).
