Researchers are studying changes in body weight among male prisoners in Martinique between the time of jail admission and three months later. The study aims to understand how physical activity, nutrition, and psychological state relate to weight change during incarceration. This is important because weight changes in prisoners can signal health issues, and Martinique has higher rates of overweight and diabetes compared to the national average. The study includes men aged 18 to 44 who are newly admitted to the only jail in Martinique and consent to participate. At admission, participants complete questionnaires about their physical activity, nutrition, and psychological state before incarceration, and their weight and other body measurements are taken. Three months later, a research technician revisits the prisoners to repeat questionnaires and measurements, and to collect information on any new treatments or tobacco use. Participants will be involved in two main visits the initial medical exam at admission and a follow-up interview three months later. During these visits, weight, body mass index, waist size, lean mass, body fat, body water percentage, visceral fat, and basal metabolic rate will be measured. Changes in physical activity, nutrition, psychological state, and new treatments will also be assessed. The primary outcome is the change in weight from baseline to three months. The total participation period lasts three months.
