This study aims at investigating prospective associations between body areas satisfaction (BAS), actual (objectively measured)-ideal body weight discrepancy, actual (self-reported)-ideal body weight discrepancy and BMI among adolescents from the general population.
Data were collected at three measurement points: baseline (T1), 2-month follow-up (T2), 13-month follow-up (T3) among 1011 adolescents (59.3% girls) aged 13-19 years (M = 16.30, SD = 0.82) with BMIs ranging from 15.20 to 38.78 (M = 20.01, SD = 3.33). Adolescents completed questionnaires regarding BAS (T1), actual and ideal body weight (T2). Body weight and height were measured objectively (T1 and T3).
Adolescents satisfied with most areas of their bodies had lower levels of actual (objectively measured)-ideal body weight discrepancy, which in turn predicted higher BMI, while lower levels of actual (self-reported)-ideal body weight discrepancy predicted lower BMI. No moderating effect of gender was found.
Actual-ideal weight discrepancies may operate in complex manner prompting opposite effects on BMI.
Level III, longitudinal study without control group.
本研究旨在调查普通人群中青少年的身体部位满意度（BAS）、实际（客观测量）-理想体重差异、实际（自我报告）-理想体重差异与体重指数（BMI）之间的前瞻性关联。
在三个测量点收集数据：基线（T1）、2个月随访（T2）、13个月随访（T3），研究对象为1011名年龄在13 - 19岁（平均年龄M = 16.30，标准差SD = 0.82）的青少年（女孩占59.3%），其BMI范围为15.20至38.78（平均BMI M = 20.01，标准差SD = 3.33）。青少年完成了关于身体部位满意度（T1）、实际体重和理想体重（T2）的问卷调查。客观测量了体重和身高（T1和T3）。
对身体大部分部位满意的青少年，其实际（客观测量）-理想体重差异水平较低，而这又预示着较高的BMI；而实际（自我报告）-理想体重差异水平较低则预示着较低的BMI。未发现性别有调节作用。
实际-理想体重差异可能以复杂的方式起作用，对BMI产生相反的影响。
三级，无对照组的纵向研究。
