“…Conditions that have been assessed for health impact include crowding, staffing, and the conditions of confinement (e.g., sanitation, infection control) (5, 118); disciplinary policies and practices (e.g., solitary confinement) (24,36); inmate victimization (122); opportunities for physical activity and recreation (54,113); access to healthful and appealing food (17); opportunities for social interactions with family, other inmates, and service providers (48); and availability of educational, employment, and health promotion programs (30,62).
