[Association between stages of behavior change related to physical activity and nutritional status in university students].

This study aimed to verify the association between stages of behavior change related to physical activity and nutritional status among 862 university students. Body mass index cut-off values were used to classify nutritional status. Stages of behavior change were analyzed individually and classified into active (action, maintenance) and inactive (pre-contemplation, contemplation, preparation). The most prevalent stages of behavior change were contemplation (32%) and preparation (29.5%). Among the entire sample of students, 68.4% were inactive. Prevalence rates for underweight, overweight, and obesity were 9.5%, 12.4%, and 1.7%, respectively. Students classified in the pre-contemplation stage were 5.99 times (CI95%: 2.29-15.68) and 7.98 times (CI95%: 1.41-45.32) more likely to be underweight and overweight, respectively. The university plays a fundamental role in adopting plans and actions targeting the academic community, promoting lifestyle changes through physical activity programs.
