Application Prospects of Compositional Data Analysis Method in Physical Activity and Health

Some compositional data were existed in the research field of physical activity and health, the research results will be greatly affected if the nature of "constant sum" of compositional data was ignored. Compositional data analysis method overcomes this problem and has been applied in many research fields. This study summarized the development path and methodology of compositional data analysis, and discussed the limitations of traditional studies by combining with the characteristics of movement behavior data. And lastly, this review summarized some related studies on activity behaviors which used compositional data analysis.It showed that: 1) Health effects of combined behaviors were greater than single behavior; 2) the results of traditional isolated studies were contradictory, indicating that comprehensive analysis of the association between activity behaviors and health outcomes is necessary; 3) researches on physical activity related behaviors using compositional data analysis basically supports the health benefits of oderate to vigorous-intensity physical activity(MVPA), but it was found that the maintenance of MVPA level was more meaningful. In addition, it also emphasized the importance of the reasonable allocation of the remaining time to health promotion when increasing MVPA; 4) future research in the field of physical activity and health can focus on the association between behavior patterns and health outcomes by conducting follow-up investigations.
