In the article An Increasing Socioeconomic Gap in Childhood Overweight and Obesity in China (Wei He et al., 2014) they first found that the relationship between SES and childhood obesity could be different depending on a country’s stage of economic development. They choose China as an example of developing country to prove their point. The facts they found in their article are that since 1997 China was growing fast, and in the same period, those higher-SES families had increased access to television and video games, and vehicles. The researchers then conducted a survey among children and adolescents 2 to 18 years in age from 9 provinces in China. This survey was to measure their eating behavior and physical activity which they answered by themselves if they were aged 10 years or older. If they were younger, the parents would assist with their children. After statistical analysis, their result showed an increase in the prevalence of childhood obesity from 8.2% in 1991 to 18.3% in 2006. More specifically, their figures show that the increase of children overweight density is much faster if the father or mother is educated (at least high school), live in urban area, or is a political elite while their per capital family income is increasing. One interesting fact in their article is that income level of a boy’s family is more likely to result in an overweight child, but for girls it is not a risk factor. Overall, it is a worth to read article but with some limitations.
