Objective: to describe the lifestyles according to Nola Pender’s Health Promotion Model among the adult Colombian population participating in a community intervention project. Method: a descriptive cross-sectional study in the adult Colombian population participating in a community intervention project, selected with support by community leaders from the area. The variables studied included sociodemographic data and Pender’s Health Promoting Life Profile II instrument, which evaluates responsibility in health, nutrition, physical activity, interpersonal relationships, spiritual growth, and stress management. For bivariate analysis, the non-parametric Mann-Whitney U and Kruskal-Wallis tests were used.Results: of the 165 persons invited, 117 participated. The total score in HPLP II was 137.5 (good health promoting behaviour). Regarding the overall mean by dimensions, “Spiritual growth” reached the highest mean (27.94), while “Physical activity” was the lowest (16.8). Those who were between 41 and 45 years old had higher “Responsibility in health” (Mean: 28; p= 0.039) and higher “Spiritual growth”. Women had higher “Responsibility in health” (Mean: 24; p= 0.035); those with a contributory affiliation regimen presented higher scores in “Spiritual growth” (Mean: 31; p= 0.007) and “Interpersonal Relationships” (Mean: 27; p= 0.02).Conclusion: the adult population participating in a community intervention project presented a good health promoting behaviour, particularly regarding the “Spiritual growth” dimension, and with deficiency in the “Physical activity” dimension.
