The cost-effectiveness of policies providing subsidized health goods is often compromised by limited use of the goods provided. Through a randomized trial involving 251 primary schools in western China, we tested two approaches to improve the cost-effectiveness of a program distributing free eyeglasses to myopic children. Relative to delivery of free eyeglasses to schools, we find that providing vouchers redeemable in local optical shops modestly improved the targeting of eyeglasses to those who would use them without reducing effective coverage.

Objective: Consultation length, the time spent between patient and health care provider during a visit, is an essential element in measuring quality of health care patients receive from a primary care facility. However, the linkage between consultation length and process quality and diagnosis quality of primary care is still uncertain. This study aims to examine the role consultation length plays in delivering process quality and diagnosis quality, two central components of overall primary care quality, in rural China.

Background: In rural China, children's vision problems are very common, with many who would benefit from refractive correction not getting the care they need. This study examines whether a health information campaign that involves vision health education and a free trial of health product with free eyeglasses is effective at raising students' awareness of myopia and promoting students' eyeglasses usage.

Methods: We conducted an in-the-field randomized controlled experiment of a program providing vision health education and subsidized free eyeglasses to myopic children from 168 primary schools in rural Northwestern China in 2012.

Based on the panel data of 20,594 fourth- and fifth-grade students in the western provinces A and B in China, this paper analyzed the effect of boarding at school on the mental health of students using a combination of the propensity score matching (PSM) and difference-in-differences (DID) methods. The results showed that boarding had no significant effect on the mental health of students, but the tendency of loneliness among boarding school students was increased. Heterogeneity analysis found that fifth-grade students whose parents had both left home to work were more likely to have poorer mental health when boarding.

Background: There is a great need in low- and middle- income countries for sound qualitative and monitoring tools assessing early childhood development outcomes. Although there are many instruments to measure the developmental status of infants and toddlers, their use in large scale studies is still limited because of high costs in both time and money. The Caregiver Reported Early Development Instruments (CREDI), however, were designed to serve as a population-level measure of early childhood development for children from birth to age three, and have been used in 17 low- and middle-income countries.

Background: Empirical evidence suggests that the uptake of maternal and child health (MCH) services is still low in poor rural areas of China. There is concern that this low uptake may detrimentally affect child health outcomes. Previous studies have not yet identified the exact nature of the impact that a conditional cash transfer (CCT) has on the uptake of MCH services and, ultimately, on child health outcomes.

Background/aims: Few studies have objectively examined the quality of eye care in China. We assessed refractive care using the incognito standardised patient (SP) approach, a gold standard for evaluating clinical practice.

Methods: A total of 52 SPs were trained to provide standardised responses during eye examinations, and underwent automated and non-cycloplegic, subjective refraction by a senior ophthalmologist from Zhongshan Ophthalmologic Center, a national-level clinical and research centre.

Nearly one-quarter of all children under age 2 in China are left behind in the countryside as parents migrate to urban areas for work. We use a four-wave longitudinal survey following young children from 6 to 30 months of age to provide first evidence on the effects of parental migration on development, health, and nutritional outcomes in the critical first stages of life. We find that maternal migration has a negative effect on cognitive development: migration before children reach 12 months of age reduces cognitive development by 0.
