This study evaluates the post-treatment and short-term follow-up efficacy of, as well as participant satisfaction for, a 4-month behavioral weight control program for overweight adolescents initiated in a primary care setting and extended through telephone and mail contact.
44 overweight adolescents were randomly assigned to either a multiple component behavioral weight control intervention (Healthy Habits [HH]; n = 23) or a single session of physician weight counseling (typical care [TC]; n = 21). Weight, height, dietary intake, physical activity, sedentary behavior, and problematic weight-related and eating behaviors and beliefs were assessed before treatment, after the 4-month treatment, and at 3-month follow-up. Participant satisfaction and behavioral skills use were measured.
HH adolescents evidenced better change in body mass index z scores to post-treatment than TC adolescents. Body mass index z scores changed similarly in the conditions from post-treatment through follow-up. Behavioral skills use was higher among HH than TC adolescents, and higher behavioral skills use was related to better weight outcome. Energy intake, percentage of calories from fat, physical activity, sedentary behavior, and problematic weight-related or eating behaviors/beliefs did not differ by condition or significantly change over time independent of condition. The behavioral intervention evidenced good feasibility and participant satisfaction.
A telephone- and mail-based behavioral intervention initiated in primary care resulted in better weight control efficacy relative to care typically provided to overweight adolescents. Innovative and efficacious weight control intervention delivery approaches could decrease provider and participant burden and improve dissemination to the increasing population of overweight youth.
本研究评估了一项针对超重青少年开展的为期4个月的行为体重控制项目的治疗后及短期随访疗效,以及参与者的满意度。该项目在初级保健机构启动,并通过电话和邮件联系进行扩展。
44名超重青少年被随机分配到多成分行为体重控制干预组(健康习惯组[HH];n = 23)或单次医生体重咨询组(常规护理组[TC];n = 21)。在治疗前、4个月治疗后及3个月随访时评估体重、身高、饮食摄入、身体活动、久坐行为以及与体重相关和饮食相关的问题行为及信念。测量参与者的满意度和行为技能使用情况。
与TC组青少年相比,HH组青少年在治疗后体重指数z评分的变化更明显。从治疗后到随访期间,两组的体重指数z评分变化相似。HH组青少年的行为技能使用率高于TC组,且行为技能使用率越高,体重结果越好。能量摄入、脂肪热量百分比、身体活动、久坐行为以及与体重相关或饮食相关的问题行为/信念在两组间无差异,且不随时间独立于组间显著变化。行为干预显示出良好的可行性和参与者满意度。
相对于通常为超重青少年提供的护理,在初级保健机构启动的基于电话和邮件的行为干预在体重控制方面具有更好的疗效。创新且有效的体重控制干预实施方法可以减轻提供者和参与者的负担,并改善对不断增加的超重青少年人群的推广。
