Children's health has made tremendous strides over the past century. In general, life expectancy has increased by more than thirty years since 1900 and much of this improvement is due to the reduction of infant and early childhood mortality. Given this trajectory toward a healthier childhood, we begin the 21st-century with a shocking developmentâ€"an epidemic of obesity in children and youth. The increased number of obese children throughout the U.S. during the past 25 years has led policymakers to rank it as one of the most critical public health threats of the 21st-century. Preventing Childhood Obesity provides a broad-based examination of the nature, extent, and consequences of obesity in U.S. children and youth, including the social, environmental, medical, and dietary factors responsible for its increased prevalence. The book also offers a prevention-oriented action plan that identifies the most promising array of short-term and longer-term interventions, as well as recommendations for the roles and responsibilities of numerous stakeholders in various sectors of society to reduce its future occurrence. Preventing Childhood Obesity explores the underlying causes of this serious health problem and the actions needed to initiate, support, and sustain the societal and lifestyle changes that can reverse the trend among our children and youth.

Abstract: In 2003, after over 20 years of minimal health insurance coverage in rural areas, China launched a heavily subsidized voluntary health insurance program for rural residents. The authors use program and household survey data, as well as health facility census data, to analyze factors affecting enrollment into the program and to estimate its impact on households and health facilities. They obtain estimates by combining differences-in-differences with matching methods. The authors find some evidence of lower enrollment rates among poor households, holding other factors constant, and higher enrollment rates among households with chronically sick members. The household and facility data point to the scheme significantly increasing both outpatient and inpatient utilization (by 20-30 percent), but they find no impact on utilization in the poorest decile. For the sample as a whole, the authors find no statistically significant effects on average out-of-pocket spending, but they do find some-albeit weak-evidence of increased catastrophic health spending. For the poorest decile, by contrast, they find that the scheme increased average out-of-pocket spending but reduced the incidence of catastrophic health spending. They find evidence that the program has increased ownership of expensive equipment among central township health centers but had no impact on cost per case.
