To determine if the sex of the participating parent/child pair is a contributing factor in initial weight loss and maintenance within a family-based obesity treatment program.
A 2-year family-based obesity treatment program targeting one overweight parent and one overweight child.
One overweight parent (body mass index (BMI) > or = 25) and child (> or = 85th BMI percentile) from 164 families.
Parameters of body weight, including height, weight, BMI, z-BMI, percent overweight (BOV) at baseline and at 6-, 12- and 24-month follow-up time points.
Children within the opposite-sex dyads had greater weight loss (P < 0.01) at 6- and 12-month time points compared with children in the same-sex dyads. Parents within opposite-sex dyads had significantly greater weight loss at 24 months (P < 0.05) compared with those in the same-sex dyads. When individual dyads were examined, the change in child z-BMI after 6 months was greater for the mother-son dyad as compared to the mother-daughter and father-son (P < 0.05). For parent z-BMI, the mother-daughter dyad consistently exhibited the poorest results. At 6- and 12-month time points, parents in the mother-daughter dyad lost significantly less weight than parents in all other dyads (P < 0.05), and at 24 months, parents in the mother-daughter dyad lost less weight than parents in the opposite-sex dyads (P < 0.05).
These data reveal that child-parent sex interactions can strongly influence the outcome of obesity treatment when both parent and child are the target for weight loss. The reasons that underlie this effect remain to be determined.
确定参与的父母/子女对的性别是否是基于家庭的肥胖治疗计划中初始体重减轻和体重维持的一个影响因素。
一项为期两年的基于家庭的肥胖治疗计划，针对一名超重父母和一名超重儿童。
来自164个家庭的一名超重父母（体重指数（BMI）≥25）和一名儿童（BMI百分位数≥85）。
体重参数，包括基线时以及6个月、12个月和24个月随访时间点的身高、体重、BMI、z-BMI、超重百分比（BOV）。
与同性配对的儿童相比，异性配对的儿童在6个月和12个月时间点体重减轻更多（P<0.01）。与同性配对的父母相比，异性配对的父母在24个月时体重减轻显著更多（P<0.05）。当对单个配对进行检查时，与母女和父子配对相比，母子配对中儿童z-BMI在6个月后的变化更大（P<0.05）。对于父母的z-BMI，母女配对始终表现出最差的结果。在6个月和12个月时间点，母女配对中的父母体重减轻明显少于所有其他配对中的父母（P<0.05），在24个月时，母女配对中的父母体重减轻少于异性配对中的父母（P<0.05）。
这些数据表明，当父母和孩子都是减肥目标时，儿童-父母性别互动会强烈影响肥胖治疗的结果。这种影响背后的原因仍有待确定。
