Abstract: Social interactions in infancy have implications for long-term outcomes. This study uses data from a sample of 1412 rural Chinese infants aged 6–12 and 24–30 months to examine the relationship between peer interactions and cognitive development. Over 75% of the infants in this sample had less than three peers and around 20% had no peers in both periods. The prevalence of cognitive delays is high within this sample and increases as infants age. Multivariate analysis reveals that peer interaction is significantly associated with cognitive development. Heterogeneous analysis suggests that peer interactions and mental development may be related to the child’s primary caregiver and the distance from the child’s household to the center of their village.

Objective To investigate the situation of parenting behavior and related risk factors in infants aged 18~30 months from rural areas of southern Shaanxi Province. Methods A total of 1,243 infants and their families from rural areas of southern Shaanxi Province, China. A multivariate regression analysis and T-test were performed to determine the risk factors for the parenting behavior in caregivers. Results 1) The mother was the primary caregiver for 67.34% of the children in the sample. For these infants, 10.62% of the mothers had completed fewer than 9 years of schooling; 2) the interaction between caregiver and infants was not enough, and the interaction time was too short. 13.68% of caregivers read to their children. Similarly, 38.37% of caregivers sing to their children on the day prior to survey administration. 39.9% of parents used toys to play with their children on the day prior to survey administration. Most sample households (90%) hit the infants sometimes or often. 3) The multivariate regression analysis showed that schooling of caregiver, whether the caregiver has internet, whether the caregiver has a telephone, and the assets of the household have significant impact on the parenting behavior (P<0.01). Conclusion Improving the schooling and internet rate in rural areas can decrease the risk of development in infants.

Abstract: More than 60 million children in rural China are “left-behind”—both parents live and work far from their rural homes and leave their children behind. This paper explores differences in how left-behind and non-left-behind children seek health remediation in China’s vast but understudied rural areas. This study examines this question in the context of a program to provide vision health care to myopic rural students. The data come from a randomized controlled trial of 13,100 students in Gansu and Shaanxi provinces in China. The results show that without a subsidy, uptake of health care services is low, even if individuals are provided with evidence of a potential problem (an eyeglasses prescription). Uptake rises two to three times when this information is paired with a subsidy voucher redeemable for a free pair of prescription eyeglasses. In fact, left-behind children who receive an eyeglasses voucher are not only more likely to redeem it, but also more likely to use the eyeglasses both in the short term and long term. In other words, in terms of uptake of care and compliance with treatment, the voucher program benefitted left-behind students more than non-left-behind students. The results provide a scientific understanding of differential impacts for guiding effective implementation of health policy to all groups in need in developing countries.

This study aims to investigate the developmental status of rural Chinese children, the extent of interactive parenting they receive, and the relation between the two. A sample of 448 six to eighteen-month-old children and their caregivers were randomly selected from two rural counties in Hebei and Yunnan provinces. According the third edition of the Bayley Scales of Infant and Toddler Development, 48.7% of sample children exhibited cognitive delays, 40.6% language delays, and 35% social-emotional delays. According to responses from caregivers, parenting in rural China is largely passive, lacking in interactive practices like storytelling, singing, and playing. Children-with-siblings, left-behind children, and children with less-educated mothers were even less likely to receive interactive practices. Children of caregivers who did engage in best parenting practices showed better cognitive, language, and socialemotional development; however, the public health system provides no platform for learning about optimal parenting.

Improving health has been a focus of Indonesia as it strives to implement universal healthcare nationwide. Yet as the government tries to achieve that ambitious goal, it finds not unlike other developing countries that poorer patients are struggling to access care, due to a number of environmental and financial constraints.

A set of conditional cash transfer (CCT) programs—a system in which patients are incentivized to seek care upon the promise of a stipend—were introduced in 2007 as an approach to improve health among poor households in Java, Indonesia’s most populous island, and a few provinces outside of Java. The programs specifically sought to better maternal and child health outcomes.

Evaluating those pilot CCT programs is the focus of a newly published paper by former Asia Health Policy Program postdoctoral fellow Margaret Triyana: “Do Health Care Providers Respond to Demand-Side Incentives? Evidence from Indonesia,” an outcome of her research completed at Stanford’s Shorenstein Asia-Pacific Research Center from 2013-14.

Triyana found that the CCT programs increased demand for healthcare providers, and consequently, prices for healthcare services. While the programs led more patients to show up for services, they also may have limited access for some patients who were unable to afford services following an eventual bump up in cost.

Triyana concludes that policymakers should forecast effects on supply and demand before implementing CCT programs in order to plan and adjust the quantity of healthcare providers as needed. Such an approach could keep prices steady and in turn allow a greater pool of patients to access care, she writes.

The paper appears in the November edition of American Economic Journal: Economic Policy.

Triyana, now a professor at Nanyang Technological University in Singapore, shared in an earlier interview her research plans and initial findings. Read the Q&A here or tune in to a podcast from her research presentation here.

China’s recent initiatives to deepen health reform, control antimicrobial resistance, and strengthen primary health services are the topics of ongoing collaborative research by the Asia Health Policy Program (AHPP) at Stanford’s Shorenstein Asia-Pacific Research Center and Chinese counterparts. For example, with generous support from ACON Biotechnology and in partnership with the ACON Biotech Primary Care Research Center in Hangzhou, China, AHPP hosts an annual conference on community health services and primary health care reform in China.

The conference, titled Forum on Community Health Services and Primary Health Care Reform, was held in June at the Stanford Center at Peking University (SCPKU) in Beijing. It featured distinguished policymakers, providers and researchers who discussed a wide-range of topics from China’s emerging “hierarchical medical system” for referring patients to the appropriate level of care (fenji zhenliao), as well as the practice and challenges of innovative approaches to primary care and integrated medical care systems. Yongquan Chen, director of Yong’an City Hospital and representative for the mayor’s office of Sanming, talked about health reforms in Sanming City, Fujian Province, a famous example within China. He discussed the incentives and reasoning behind the reforms, which focus on removing incentives for over-prescription of medications, demonstrating government leadership for comprehensive reforms, consolidating three agencies into one, monitoring implementation and easing tensions between doctors and patients. He pointed out the feasibility and early successes of reform by comparing public hospitals in the city in terms of their revenues and costs, reduced reliance on net revenue from medication sales, and other dimensions of performance. Finally, he addressed reform implementation and future plans on both the hospital's and the government's part.

Xiaofang Han, former director of the Beijing Municipal Development and Reform Commission, shared her personal views on the challenges patients face in navigating China’s health system (kan bing nan) and the need to improve the structure of the delivery system, including a revision to the incentives driving over-prescription in China’s fee-for-service payment system. She emphasized that patients’ distrust of primary care providers can only be overcome by demonstrating improved quality (e.g. with a systematic training program for general practitioners, GPs), and that referral systems should be based on the actual capabilities of the clinicians, not their formal labels. To reach China’s goal of over 80 percent of patients receiving management and first-contact care within their local communities will require improved training and incentive programs for newly-minted MDs, a more flexible physician labor market, and innovations in e-health and patient choice regarding gatekeeping or “contract physician services” (qianyue fuwu).        

Guangde County People's Hospital Director Mingliang Xu spoke about practices and exploration of healthcare alliances and initiatives to provide transparent incentives linking medical staff bonuses to metrics of quality. Ping Zhu from Community Healthcare Service Development and Research Center in Ningbo addressed building solid relationships between doctors and residents and providing more patient-centered services.        

Professor Yingyao Chen from Fudan University School of Public Health discussed performance assessment of community health service agencies based on his research in Shanghai. He introduced the strengths and weaknesses of the incentives embedded in the assessment system for China’s primary care providers, and concluded with suggestions for future research. Dr. Linlin Hu, associate professor at Peking Union Medical College, discussed China's progress and challenges of providing universal coverage of national essential public health services.

Professor Hufeng Wang of Renmin University of China discussed China’s vision for a “hierarchical medical system”– bearing resemblance to “integrated care,” “managed care,” or NHS-like coordination of primary and specialized care – with examples of pilot reforms from Xiamen, Zhenjiang and Dalian cities. Dr. Zuxun Lu, professor of Tongji Medical College of Huazhong University of Science and Technology, also discussed hierarchical medical systems and declared that China currently had a “discounted gatekeeper system.”

Dr. Yaping Du of Zhejiang University presented his research on mobile technology for management of lipid levels and with the help of a volunteer, demonstrated “Dyslipidemia Manager,” a mobile app-based product for both patients and doctors. Innovative strategies for primary prevention of cardiovascular diseases in low- and middle-income countries were the focus of remarks by Dr. Guanyang Zou from the Institute for Global Health and Development at Queen Margaret University, including its connections to international experiences with China’s current efforts in that area.  

In sum, the 2016 Forum elicited lively, evidence-based discussions about the opportunities and challenges in improving primary care and sustaining universal coverage for China.  Plans are underway for convening the third annual ACON Biotech-Stanford AHPP Forum on Community Health Services and Primary Health Care Reform in June 2017 at SCPKU. Anyone with original research or innovative experiences with primary care in China may contact Karen Eggleston regarding participation in next year’s Forum.
