Health and Medicine

FSI’s researchers assess health and medicine through the lenses of economics, nutrition and politics. They’re studying and influencing public health policies of local and national governments and the roles that corporations and nongovernmental organizations play in providing health care around the world. Scholars look at how governance affects citizens’ health, how children’s health care access affects the aging process and how to improve children’s health in Guatemala and rural China. They want to know what it will take for people to cook more safely and breathe more easily in developing countries.

FSI professors investigate how lifestyles affect health. What good does gardening do for older Americans? What are the benefits of eating organic food or growing genetically modified rice in China? They study cost-effectiveness by examining programs like those aimed at preventing the spread of tuberculosis in Russian prisons. Policies that impact obesity and undernutrition are examined; as are the public health implications of limiting salt in processed foods and the role of smoking among men who work in Chinese factories. FSI health research looks at sweeping domestic policies like the Affordable Care Act and the role of foreign aid in affecting the price of HIV drugs in Africa.

Paragraphs

Using individual data collected in rural China and adopting Heckman’s two-step function, we examined the impact of childcare and eldercare on laborers’ off-farm activities. Our study finds that having school-aged children has a negative impact on rural laborers’ migration decisions and a positive impact on their decision to work in the local off-farm employment market. As grandparents can help to take care of young children, the impact of preschoolers is insignificant. Having elderly family to care for decreases the income earned by female members of the family. Although both men and women are actively engaged in off-farm employment today in rural China, this study shows that women are still the primary care providers for both children and the elderly. Therefore, reforming public school enrollment and high school/college entrance examination systems so that migrant children can stay with their parents, this will help rural laborers to migrate to cities. The present study also calls for more public services for preschoolers and the elderly in rural China.

Findings: The major results are that although the factors driving the decisions on health insurance participation are basically the same for rural and urban citizens, the participation levels are quite different. The major difference is that urban SHI has higher coverage and urban citizens have higher income, resulting in a much larger urban medical expenditure.

In this paper we have two objectives - one empirical; one methodological. Although China's leaders are beginning to pay attention to health care in rural China, there are still concerns about access to health services. To examine this issue, we use measure of travel distances to health services to examine the nature of coverage in Shaanxi Province, our case study. The mean distance by road to the nearest health center is more than 6 km. When we use thresholds for access of 5 and 10 km we find that more than 40 (15) percent of the population lives outside of these 5 (10) kilometer service areas for health centers. The nature of the access differs by geographical region and demographic composition of the household.. The methodological contribution of our paper originates from a key feature of our analysis in which we use Geographic Information System (GIS) network analysis methods to measure traveling distance along the road network. We compare these measures to straight-line distance measures. Road distances (produced by network analysis) produce measures (using means) that are nearly twice as great as straight-line distances. Moreover, the errors in the measures (that is, the difference between road distances and straight-line distances) are not random. Therefore, traditional econometric methodsof ameliorating the effects of measurements errors, such as instrument variables regression, will not produce consistent results when used with straight-line distances.

Background: Empty-nest elderly refers to those elderly with no children or whose children have already left home. Few studies have focused on healthcare service use among empty-nest seniors, and no studies have identified the prevalence and profiles of non-use of healthcare services among empty-nest elderly. The purpose of this study is to compare the prevalence of non-use of healthcare services between empty-nest and non-empty-nest elderly and identify risk factors for the non-use of healthcare services among empty-nest seniors.

Methods: Four thousand four hundred sixty nine seniors (60 years and above) were draw from a cross-sectional study conducted in three urban districts and three rural counties of Shandong Province in China. Non-visiting within the past 2 weeks and non-hospitalization in previous year are used to measure non-use of healthcare services. Chi-square test is used to compare the prevalence of non-use between empty-nesters and non-empty-nesters. Multivariate logistic regression analysis is employed to identify the risk factors of non-use among empty-nest seniors.

Results: Of 4469 respondents, 2667(59.7 %) are empty-nesters. Overall, 35.5 % of the participants had non-visiting and 34.5 % had non-hospitalization. Non-visiting rate among empty-nest elderly (37.7 %) is significantly higher than that among non-empty-nest ones (32.7 %) (P = 0.008). Non-hospitalization rate among empty-nesters (36.1 %) is slightly higher than that among non-empty-nesters (31.6 %) (P = 0.166). Financial difficulty is the leading cause for both non-visiting and non-hospitalization of the participants, and it exerts a larger negative effect on access to healthcare for empty-nest elderly than non-empty-nest ones. Both non-visiting and non-hospitalization among empty-nest seniors are independently associated with low-income households, health insurance status and non-communicable chronic diseases. The nonvisiting rate is also found to be higher among the empty-nesters with lower education and those from rural areas.

Conclusions: Our findings indicate that empty-nest seniors have higher non-use rate of healthcare services than non-empty-nest ones. Financial difficulty is the leading cause of non-use of health services. Healthcare policies should be developed or modified to make them more pro-poor and also pro-empty-nested.

Purpose

The purpose of this paper is to evaluate the effect of adult children migration on the health status of elderlyparents. Increased labor migration in developing countries that lack adequate social security systems and institutionalized care for the elderly is a phenomenon that is important to understand. When their adultchildren go away to work, it is not clear what effect there will be on “left-behind” elderly parents.

Design/methodology/approach

This study employs nearly nationally representative data from five provinces, 25 counties, 101 villages and 2,000 households, collected from two waves of data in 2007 and 2011. This sample comprises a subset of households which include both elderly individuals (above 60 years old) and their grown (working-aged)children in order to estimate the impact of adult child migration on the health of elderly parents in ruralChina.

Findings

This study finds that adult child migration has a significant positive impact on the health of elderly family members.

Practical implications

These findings are consistent with the explanation that migration raises family resources, which in turn may contribute to better health outcomes for elderly household members.

Originality/value

This is the first paper to attempt to identify the relationship between household migration and the health of elderly parents within the Chinese context.

Purpose

The purpose of this paper is to measure the turnover (or stability in employment) of village clinicians in rural China over the past decade. The authors also want to provide quantitative evidence on the individual characteristics of the clinicians who provide health care to villagers in rural China and whether we should expect these individuals to be interested in continuing to supply quality health care in China’s villages in the coming years.

Design/methodology/approach

This paper uses data from a survey of rural China’s village clinicians conducted in five provinces, 25 counties, and 101 villages in 2005 and 2012. This paper also uses qualitative data from interviews with 31 village clinicians. Using a mixed methods approach, this study describes the turnover of village clinicians and the main factors that impact the career decisions of clinicians.

Findings
Turnover of China’s village doctors, while not trivial (about 25 percent of village doctors exited their field between 2005 and 2012), is still not overly high. Only five out of 101 villages did not have village clinicians in 2012. Of those that lost village doctors between 2005 and 2012, nearly all of them still had a village doctor in 2012 (either taken over by another local clinician or the position was taken by a newcomer). The authors find that three main sets of factors are correlated with the career decisions of village clinicians: village clinicians’ opportunity cost, the profitability of running a village clinic, and commitment to the field of medicine. In general, clinicians who left the village faced a much higher opportunity cost, had been running a clinic that was not profitable, and had fewer ties to the field of medicine. Newcomers over the same period had higher levels of education, went to higher profit clinics between 2005 and 2012, and had a stronger commitment to the field.
Originality/value

This study makes use of a data set with a large and nationally representative sample to provide a new perspective to better understand clinician turnover at village clinics, the career decisions of clinicians, and the implied trends for the quality and access to rural health care services in the future.

The debate over whether boarding school is beneficial for students still exists in both developing and developed countries. In rural China, as a result of a national school merger program that began in 2001, the number of boarding students has increased dramatically. Little research has been done, however, to measure how boarding status may be correlated with nutrition, health and educational outcomes. In this paper, we compare the outcomes of boarding to those of non-boarding students using a large, aggregate dataset that includes 59 rural counties across five provinces in China. We fi nd that for all outcomes boarding students perform worse than non-boarding students. Despite these differences, the absolute levels of all outcomes are low for both boarding and non-boarding students, indicating a need for new policies that will target all rural students regardless of their boarding status.

Purpose

  • Many public health systems have struggled with the dual questions of: why the uptake rate of maternal health (MH) services is low among some subpopulations; and how to raise it. The purpose of this paper is to assess the uptake rate of a new set of MH services in poor rural areas of China.
 

Design/methodology/approach

  • The analysis is based on the survey responses of women’s representatives and village cadres from almost 1,000 villages in June 2012 as part of a wide-scale public health survey in Sichuan, Gansu and Yunnan provinces in the western part of China.
 

Findings

  • The authors find that the uptake rate of MH services (including in-hospital delivery, antenatal care visits and post-partum care visits) in poor rural areas of Western China are far below average in China, and that the rates vary across provinces and ethnic groups. The analyses demonstrate that distance, income, ethnicity and availability appear to be systematically correlated with low uptake rates of all MH services. Demand-side factors seem to be by far the most important sources of the differences between subpopulations. The authors also find that there is potential for creating a Conditional Cash Transfer program to improve the usage of MH services.
 

Originality/value

  • The authors believe that the results will contribute positively to the exploration of answers to the dual questions that many public health systems have struggled with: why the uptake rate of MH services is low among some subpopulations; and how to raise it.

Objectives: To test whether text message reminders sent to caregivers will improve the effectiveness of a home micronutrient fortification program in western China.

Methods: A cluster-randomized controlled trial was carried out in 351 villages in Shaanxi province in 2013-14. We enrolled children aged 6-12 months in target villages. Each village/cluster was randomly assigned into one of three groups: Free Delivery Group (FDG; caregivers received free micronutrient packets); Text Messaging Group (TMG; FDG treatment plus daily text message); and Control Group. We collected information on compliance with treatments and hemoglobin concentrations from all children at baseline and 6-month follow-up. We estimated the intent-to-treat (ITT) effects on compliance and child anemia using a logistic regression model, controlling for infant, caregiver and household characteristics.

Results: There were 1393 eligible children. We found that assignment to TMG led to an increase full compliance (marginal effect = 0.10, 95% CI = 0.03, 0.16) and decrease in the rate of anemia at endline (marginal effect=-0.07, 95% CI= -0.12, -0.01).

Conclusions: Text messages improved compliance of caregivers to a home fortification program and children’s nutrition.

Abstract: The general goal of the present study is to analyze whether children with siblings lag behind their only-child counterparts in terms of health and nutrition, cognition and educational performance, and non-cognitive outcomes. We draw on a dataset containing 25 871 observations constructed from three school-level surveys spanning four provinces in China. The analysis compares children with siblings and only children aged 9 to 14 years old in terms of eight different health, cognitive and non-cognitive indicators. We find that with the exception of the anemia rate, health outcomes of children with siblings are statistically indistinguishable from those of only children. In terms of cognition, children with siblings performed better than only children. Moreover, outcomes of children with siblings are statistically indistinguishable from those of only children in terms of the non-cognitive outcomes provided by measures of anxiety. According to our results, the same general findings are true regardless of whether the difference between children with and without siblings is disaggregated by gender.
