背景：本研究评估了对无家可归的成年人进行饮食和体育活动干预的可行性和有效性。研究方法：庇护所居民（N = 32）被随机分配到为期4周的饮食和体力活动干预（n = 17）或评估仅控制组（n = 15）。干预参与者收到量身定制的教育通讯，步数与步目标，每天两次水果/蔬菜零食。关键措施包括24小时饮食回忆访谈和加速度计测量的中度到剧烈强度的体力活动（MVPA）。结果如下：在基线时，68.8%的参与者超重或肥胖，93.8%的人报告食物不安全，43.8%的人报告活动水平低于身体活动指南。基线饮食回忆访谈表明，与当前的饮食建议相比，水果/蔬菜消费量较低，添加糖、饱和脂肪和钠的摄入量较高。在为期4周的研究期间，干预参与者参与了显著更高的加速度计测量的每日MVPA（P
Background: The current study evaluated the feasibility and effectiveness of a diet and physical activity intervention for homeless adults. Methods: Shelter residents (N = 32) were randomly assigned to a 4-week diet and physical activity intervention (n = 17) or an assessment-only control group (n = 15). Intervention participants received tailored educational newsletters, pedometers with step goals, and twice daily fruit/vegetable snacks. Key measures included 24-hour dietary recall interviews and accelerometer-measured moderate-to-vigorous intensity physical activity (MVPA). Results: At baseline, 68.8% of participants were overweight or obese, 93.8% reported food insecurity, and 43.8% reported activity levels below physical activity guidelines. Baseline dietary recall interviews indicated low fruit/vegetable consumption, and elevated intake of added sugar, saturated fat, 'and sodium relative to current dietary recommendations. During the 4-week study period, intervention participants engaged in significantly greater accelerometer-measured daily MVPA (P
