Clustering of physical inactivity and low fruit and vegetables intake and associated factors in young adults Agregamento entre a inatividade física e consumo de frutas, legumes e verduras e fatores associados em adultos jovens Rafael Miranda TASSITANO 1 Maria Cecília Marinho TENÓRIO 1 Poliana Coelho CABRAL 2 Giselia Alves Pontes da SILVA 3 A B S T R A C T Objective To investigate the cluster of physical inactivity and low fruit and vegetable intake and the associated factors in university students. Methods This cross-sectional study included a representative sample (n=717) of Universidade Federal Rural de Pernambuco students. Low fruit and vegetable intake was defined as an intake of less than five servings a day and physical inactivity was defined as exercising less than 150 minutes a week. The independent variables were gender, age, socioeconomic status, school year, shift, and study time. Clustering was determined by comparing the observed prevalence with the expected prevalence for all possible risk-factor combinations. Logistic regression analysis, performed by the software Statistical Package for the Social Sciences 17.0 with a significance level of 5% (p<0.05), considered the presence of both risk behaviors adjusted to the independent variables. Results The prevalence of low fruit and vegetable intake was 81.7% (CI95%=78.1-84.3) and of physical inactivity was 65.8% (CI95%=62.2-69.4). Most students (58.6%, CI95%=55.3-62.2) were exposed to both risk factors simultaneously, while 11.0% (CI95%=8.9-13.5) were exposed to neither. Full-time students have a risk 1.45
