本研究旨在探讨不同的自我监控饮食和运动行为的方法是否会影响超重成年人的自我监控过程和体重变化。42名受试者参加了为期16周的通信为基础的减肥干预使用前测后测随机设计。规定饮食摄入量为1，200至1，500千卡/天，膳食脂肪< 30%。体力活动进展至200分钟/周。参与者被随机分配到使用传统的详细方法或过渡到简化方法的自我监测饮食和身体活动行为。过渡到一个简短的方法返回显着更多的日记比使用传统的详细方法（P=0.04）。完成研究的参与者显示，传统详细方法（-7.5 +/- 5.3 kg）和简化方法（-7.6 +/- 5.5 kg）之间的体重减轻没有显着差异，意向治疗分析的结果相似（详细方法-3.9 +/- 5.3 kg vs简化方法-4.3 +/- 5.8 kg）。体重减轻与完成自我监测日记的数量显著相关（r=0.53，P < 0.05）。研究结果表明，自我监测过程，而不是自我监测的细节，是促进减肥和饮食和体育活动行为的变化很重要。过渡到简化的自我监测方法不会对超重成年人的短期体重减轻产生负面影响。这些结果可能对改善超重成年人在减肥期间的自我监控有影响。
This study examined whether different methods of self-monitoring eating and exercise behaviors affect the process of self-monitoring and change in body weight in overweight adults. Forty-two subjects participated in a 16-week correspondence-based weight-loss intervention using a pretest-posttest randomized design. Dietary intake was prescribed at 1,200 to 1,500 kcal/day and < 30% dietary fat. Physical activity was progressed to 200 minutes/week. Participants were randomly assigned to self-monitoring eating and physical activity behaviors using a traditional detailed method or transitioning to an abbreviated method. Transitioning to an abbreviated method returned significantly more diaries than using a traditional detailed method (P=0.04). Participants completing the study showed no significant difference in weight loss between the traditional detailed method (-7.5 +/- 5.3 kg) and the abbreviated method (-7.6 +/- 5.5 kg), with similar results for intention-to-treat analysis (detailed method -3.9 +/- 5.3 kg vs abbreviated method -4.3 +/- 5.8 kg). Weight loss was significantly associated with number of self-monitoring diaries completed (r=0.53, P < 0.05). Findings suggest the self-monitoring process, rather than the detail of self-monitoring, is important for facilitating weight loss and change in eating and physical activity behaviors. Transitioning to a simplified approach to self-monitoring does not negatively affect short-term weight loss in overweight adults. These results may have implications for improving self-monitoring in overweight adults during periods of weight loss.
