The results showed that the realistic themes for sedentary behavior are that the critical transmission between sedentary behavior and the low-intensity physical activity, and the breakup of continuity with sedentary behavior, and its future development tendency may be to implement cross-discipline health education, building public information settings, developing multi-dimensional measurement tools, exploring physiological and biochemical mechanism. Key words: sedentary behavior；physical activity；energy expenditure；chronic disease；public health
