Research supports the use of family-based interventions in the treatment of obesity in children, but there is a lack of knowledge about what factors affect parents' ability to carry out the lifestyle changes necessary to reduce their child's obesity. The aim of the present study was to examine whether parents' self-efficacy, perceived emotional barriers, subjective norms, and attitudes could predict change in their children's body fat at 6 month and 2 year follow-ups after a family-based treatment of obesity.
Body Mass Index Standard Deviation Scores (BMI SDS) were calculated and body fat (dual-energy X-ray absorptiometry) were measured in 99 treatment-seeking children with obesity (ages 7-12; 48 girls, 51 boys; mean BMI SDS = 2.99) at baseline, after 6 month and after 2 year follow-up. Parental cognitions regarding diet and physical activity were examined by parent-completed questionnaires. Structural equation modeling (SEM) was used to test whether the selected health cognitions could predict treatment outcome.
Parental perceived emotional barriers was a significant predictor of change in body fat at 6 month (β = -.32, p = .001) and 2 year (β = -.38, p = .002) follow-up when the initial body fat values were controlled. Self-efficacy, subjective norms and attitudes did not improve the amount of variance explained.
Parents' perceived emotional barriers significantly predict change in total body fat in children treated for obesity. In order to increase treatment-efficacy, perceived emotional barriers should be addressed.
研究支持在儿童肥胖治疗中使用基于家庭的干预措施，但对于哪些因素会影响父母实施必要的生活方式改变以降低孩子肥胖的能力知之甚少。本研究旨在探讨父母的自我效能感、感知的情感障碍、主观规范和态度是否可以预测儿童肥胖的家庭治疗后 6 个月和 2 年随访时孩子体脂肪的变化。
计算体重指数标准差评分（BMI SDS），并使用双能 X 射线吸收法测量 99 名寻求治疗的肥胖儿童（年龄 7-12 岁；48 名女孩，51 名男孩；平均 BMI SDS=2.99）的基线、6 个月和 2 年随访时的体脂肪。通过家长完成的问卷来检查父母对饮食和体育活动的认知。采用结构方程模型（SEM）来检验所选健康认知是否可以预测治疗效果。
当控制初始体脂值时，父母感知的情感障碍是 6 个月（β=-.32，p=0.001）和 2 年（β=-.38，p=0.002）随访时体脂变化的显著预测因子。自我效能感、主观规范和态度并不能提高方差解释量。
父母感知的情感障碍可显著预测接受肥胖治疗的儿童的总体脂肪变化。为了提高治疗效果，应解决感知的情感障碍问题。
