title: [Stages of change related to fruit and vegetables consumption, physical activity, and weight control in Chilean university students].
abstract: In order to design effective health promotion interventions, nutritional status and the stages of change related to the consumption of fruit and vegetables, physical activity, and weight control were determined in 955 students of both genders at the University of Bio-Bio, Chile. The sample was randomly selected by campus, faculty, and career, with a level of confidence of 95% and a maximum error of 3%. Beside the descriptive analysis, to evaluate the association among nutritional status, fruit and vegetables consumption, physical activity and weight control, Chi2 test was applied. Nutritional status was determined by Body Mass Index and WHO reference standards for adults. A questionnaire previously validated by INTA was applied to evaluate the stages of change. The prevalence of overweight and obesity reached 48.2% in men and 25.5% in women (p<0.0001). Only 3.1% of men and 7.3% of women consumed the 5 recommended daily servings of fruit and vegetables. The majority consumed 1 or 2 daily servings (69.5% men and 54.3% women), and the rest 3 to 4 servings (18.2% and 34.7%, respectively) (p<0.0001). 58% of men and 43% of women carried out physical activity regularly (p<0.0001). 73.1% of men and 79.3% of women were trying to reduce or not to increase their weight (p<0.0002). It is concluded that students require specific interventions and appropriate conditions to increase their fruit and vegetables consumption, and physical activity.
