Few studies explored the reasons for the rapid increases in overweight plus obesity (BMI ≥ 25) in Henan, one of the largest provinces in China with >; 100 million populations. This study's goal was to analyze the dynamic changes in physical activity (PA) and the association between PA and BMI ≥ 25. A subsample from the China Health and Nutrition Survey was used. Multinominal logistic regression was used to assess the association between PA and BMI ≥ 25. PA levels significantly decreased and screen time significantly increased with constant improvement in transportation and technology in Henan province. As a result, overweight and obesity (BMI ≥ 25) more than tripled from below 10% in 1989 to 35% in 2009 and over 40% in urban areas, even though energy intake decreased by 25% during the same period. Decreased PA significantly increased the risk of overweight and obesity, controlled for age, sex, PA at baseline, and energy intake. Promoting PA and healthy lifestyle should be considered as the major health promotion strategy in Henan province.
