To examine associations between parent and adolescent weight change within two parent approaches to adolescent obesity treatment.
Adolescent (M = 13.7 ± 1.2 years; M = 34.9 ± 7.0 kg/m) and parent (M = 36.4 ± 7.3 kg/m) dyads (N = 82) were randomized to TEENS+Parents as Coaches (PAC) or TEENS+parent weight loss (PWL). Anthropometrics were assessed at baseline (0-month), 4 months (post) and 7 months (after 3-month maintenance period). Regression analyses examined associations between parent and adolescent ΔBMI and ΔBMI, with parent group as a moderator.
Post-treatment, parent and adolescent ∆BMI were positively related (β = 0.68, p < 0.001), with no group interaction. Parent and adolescent ΔBMI were related (β = 0.48, p = 0.012) during maintenance, moderated by parent group (β = -0.49, p = 0.010): positive relationships persisted in PAC (β = 0.39, p = 0.011), but not PWL (β = -0.19, p = 0.211).
Parent and adolescent weight changes were positively related during treatment in both parent groups. During maintenance, weight change associations persisted only in PAC. These patterns prompt further exploration of parent factors driving weight change relationships.
探讨在两种针对青少年肥胖治疗的家长参与方式中，家长与青少年体重变化之间的关联。
将青少年（平均年龄M = 13.7 ± 1.2岁；平均体重指数M = 34.9 ± 7.0kg/m²）及其家长（平均体重指数M = 36.4 ± 7.3kg/m²）组成的二元组（N = 82）随机分为“青少年+家长作为教练”（PAC）组或“青少年+家长减重”（PWL）组。在基线（0个月）、4个月（治疗后）和7个月（3个月维持期后）对人体测量指标进行评估。回归分析以家长组作为调节变量，研究家长与青少年的BMI变化量（ΔBMI）以及体重指数变化量（ΔBMI）之间的关联。
治疗后，家长和青少年的ΔBMI呈正相关（β = 0.68，p < 0.001），且无组间交互作用。在维持期，家长和青少年的ΔBMI相关（β = 0.48，p = 0.012），受家长组调节（β = -0.49，p = 0.010）：在PAC组中呈正相关关系持续存在（β = 0.39，p = 0.011），而在PWL组中则不然（β = -0.19，p = 0.211）。
在两个家长组的治疗过程中，家长和青少年的体重变化均呈正相关。在维持期，体重变化的关联仅在PAC组中持续存在。这些模式促使进一步探索推动体重变化关系的家长因素。
