Urban-Rural Disparity Of Overweight/Obesity Distribution And Its Potential Association With Breast Cancer Among Chinese Females

Background: Disparity of overweight/obesity distribution had been investigated in developed countries, but rarely been investigated in developing countries, especially for China with rapid socio-economic development in the past decades. Methods: A total of 1 210 762 participants were recruited from the Chinese National Breast Cancer Screening Program. Overweight and obesity were defined as body mass index (BMI) ranged 24.0-27.9 kg/m2 and BMI ≥ 28.0kg/m2, respectively. Results: The prevalence of overweight/obesity for Chinese rural women (35.2%, 29.2% for overweight and 6.0% for obesity) was significantly higher than that for Chinese urban women (33.4%, 27.7% for overweight and 5.7% for obesity) (P Conclusions: There was an obvious urban-rural disparity of overweight/obesity distribution among Chinese females, which could also lead to an obvious disparity of breast cancer distribution.
