Describe how cross-cultural differences in prevalence of eating disorders and obesity are changing.
What will be an ideal response?
While cultural differences exist in the prevalence of eating disorders, some of these differences may be changing. The prevalence of eating disorders in now more similar among non-Hispanic whites, African American, Asian American, and Hispanic females. Eating disorders are generally more common among Native Americans than other ethnic groups. Additionally, eating disorders are going global. Recent studies show estimates of prevalence in China and Japan are approaching those in the United States and other Western countries. Ethnicity also is a factor in rates of obesity. In the United States, 40% to 50% of African American and Hispanic American women are obese. Rates among minority adolescents are even higher. Rates of obesity in eastern and southern European nations are as high as 50% and the rate is increasing in developing nations. In Japan, although still comparatively low, obesity rates in men have doubled since 1992 and have nearly doubled in young women. Although less extreme, increases in obesity are also occurring in China, where the proportion of Chinese who are overweight increased from 6% to 8% in a seven-year period.
