| Summary/Abstract |
Economic growth over the past three decades has greatly improved the nutrition and living standards of people in China. However, increasingly, the Chinese are becoming heavier. As many as a quarter of Chinese school-age urban boys are overweight or obese, yet a third of Chinese children remain underweight. Drawing on six national surveys of children's health conducted since 1979, the article reports on trends in nutritional status and regional disparities. It shows that the drivers behind the increase in mean body mass and in nutritional inequality are associated with rising household incomes and associated inequalities between provinces.

| Summary/Abstract |
Melanoma is an increasingly common skin cancer with approximately 200,000 new cases discovered annually worldwide. This article seeks to estimate the relationships between mortality rate from melanoma, prevalence of obesity and annual new melanoma cases per 100,000 persons in the population. By way of doing so, it uses a quadratic model to examine the possibility of the obesity survival paradox, namely, the counter-intuitive possibility that a higher prevalence of obesity reduces the mortality risk from melanoma. The outcomes support a non-monotonic relationship, with implications for treatment decisions regarding melanoma patients who are obese versus those with a normal weight (BMI < 25).

| Summary/Abstract |
China has the world's largest number of older persons and is undergoing rapid demographic and economic transitions. Using longitudinal data from seven waves of the China Health and Nutrition Survey (CHNS) spanning 1991–2009, this study examines trends by birth cohort for persons born during 1912–54 on several dimensions of elderly health—chronic diseases, physical function limitations, and excess weight. A fixed effects specification was used to distinguish trends in health, physical function, and weight common to all adult age groups and differential trends in these measures according to the person's birth year. The empirical results show that while there was a decline in physical function limitations over time, persons born in later years were more likely to experience a stroke and physical function limitations at older ages than were persons born earlier. A similar pattern occurred for stroke, but not for the other heath indicators. These findings are robust after accounting for sample attrition. The secular changes in health and function could have occurred for several reasons. Among the underlying mechanisms the data allow us to analyze, improved access to medical care and expanded health insurance coverage only had minor effects on observed changes in health and physical function.
