Prevalence of Overweight and Obesity Among Adult Women in China, Mali and United States: Evolution of Trends over Ten Years

Abstract

Objectives This article assessed trends in the prevalence of overweight and obesity over ten years among adult women. Methods A cross-sectional study was conducted using National Surveys Data from China, Mali and the United States between 2001–2002 and 2012–2013. The sample population consisted of all adult women: 140,022 (2002) and 157,850 (2012) adults aged 18 and above in China, 10,424 (2002) and 4502 (2012) women aged 15–49 in Mali, 4413 (2001) and 5181 (2012) adults aged 20 and above in the USA. The proportion test (Z test) was used to evaluate the 10-year prevalence differences in different countries. Results In ten-year period, overweight has significantly increased from 22.7% to 29.9% among Chinese women with a growth of 7.2% (P-value < 0.05) and, 11.2% to 12.9% in Malian women with a growth of 1.7% (P-value < 0.05). Among US women, overweight has increased from 28.2% to 29.7% with a non-significant growth of 1.5% (P-value >0.05). The prevalence of women's obesity in all three countries has significantly increased, more particularly in China. Conclusions Data from the National Survey over ten years showed an increase in the prevalence of overweight as well as obesity in Chinese, Malian and US women.

Overweight and obesity among women of reproductive age in Mali: what are the determinants?

“…First, factors associated with overweight and obesity are yet to be assessed in Mali, despite a report that, in 2001, 10% of women in Bamako were obese. 26 , 27 Also, Traore et al 28 examined the trends of overweight and obesity among adult women in China, Mali and the USA and found that overweight in Mali has increased from 11.2% to 12.9% between 2002 and 2012—an increase of 1.7%. This increase was greater than that recorded in the USA (1.5%) but the growth was less than that recorded in China (7.2%).…”
