Military training in extreme environments increases weight loss risk, which could affect soldiers' performance. This study aimed to assess daily energy intake and requirements of Canadian Armed Forces soldiers consuming combat rations over an 8-week Arctic training and document impact on weight and body composition. Fourteen soldiers participated (males; 31.3±5.5 years). Body weight and composition were measured at different training time-points. Energy intake was measured using food diaries. Energy requirements were estimated using a predictive equation developed for the military. Fourteen soldiers participated. Weight loss was measured (3.9±3.0 kg) for 12 participants from beginning to mid-training after a week consuming combat rations. Energy intake on rations was lower than estimated daily energy requirements and resulted in energy deficits (49.8±19.2%). No body composition changes were measured. More research is needed to explore ways to make rations better adapted to reduce energy deficit and maintain soldiers' body weight in extremely cold environments.

Au Canada, au gouvernement fédéral et dans plusieurs provinces, le principe d'offre active sert à guider la prestation des services publics en français. L'Ontario se démarque, car son approche est en partie volontaire. Il importe donc d'étudier comment les services en français sont intégrés à la gouvernance des services publics au sein de la province. Cet article puise dans les données gouvernementales existantes afin de brosser un tableau de l'offre active de services en français en santé mentale. Or, les auteurs montrent que ces données sont difficiles à obtenir et parcellaires. L'article sert à souligner des défis importants pour l'offre de services en français dans le domaine de la santé mentale en Ontario.
