Abstract: The actual portrait of the health behaviours of young adults reveals alarming data about the physical activity level (Colley, Garriguet, Janssen, Craig, Clarke & Tremblay, 2011). To help them adopt increase their physical activity level, it seems appropriate to set up interventions that mobilize the action of their peers (Canadian Institute for Research on Fitness and Lifestyle, 2014; 2015). They seem to give them special importance when the time comes to adopt healthy lifestyle habits (DuBois & Karcher, 2014). Therefore, peer mentoring seems a promising avenue. Although the characteristics of this type of intervention have been documented in the literature, few studies have evaluated its effects in mentees (Sallis, Calfas, Nichols, Sarkin, Johnson, Caparosa, Thomson & Alcaraz, 1999; Boyle, Mattern, Lassister & Ritzler, 2011) and even fewer have done so with mentors (Lubans, Morgan, Aguiar & Callister, 2011). From this perspective, the present study had two objectives: 1) to evaluate the effects of a peer mentoring program in college settings on the practice of physical activity, physical condition, eating behaviours, consumption of fruits and vegetables. and the sense of personal effectiveness of mentees and mentors; 2) explore the moderating role of gender and participants' initial level of physical activity on the effects of the program. These objectives were investigated using a study with a quasi-experimental design using 104 young adults (mentors n = 38, non-mentors n = 33, mentees n = 21 and non-mentees n = 12). Questionnaires as well as physical tests made it possible to measure the main variables. The covariance analyzes show that at the end of the intervention, mentees adopted fewer behaviours aimed at gaining weight than non-mentees, while mentors adopted fewer behaviours aimed at losing weight than non-mentors. In addition, moderation analyzes reveal effects in men regardless of their initial level of physical activity but not in women. In fact, 1) mentee men exhibit better estimated maximal volume of oxygen consumption (VO₂ max) than non-mentee men, 2) male mentors show a lower body mass index (BMI) than non-mentor men and 3) male mentors report more behaviours aimed at gaining weight than non-mentor men. However, although our results suggest these effects, it seems essential to us to interpret them with caution due to some methodological limitations, in particular the small sampling. We often see them as tendencies to take in count for future research. However, our results suggest that we must consider sex of participants when time comes to orient, implement, and operationalize mentoring programs, particularly for the mentors.
