Studies have suggested that obesity is linked within families and that successful interventions involve both the parent and child with obesity. However little information exists regarding similarities in adiposity and weight loss between the parent and child, especially in low socio-economic ethnically diverse households.
The purpose of this study was to examine the relationships between the changes from baseline over time in adiposity, weight, health behaviors, and self-efficacy in children ( = 184) and parents ( = 184) participating in an 18-month weight loss program. Within the intervention group only and for each post-baseline time point, Pearson correlation coefficients were computed for children's changes (from baseline) in adiposity, weight, health behaviors, and self-efficacy, with their parents' corresponding changes from baseline, to determine how strongly the dyads were correlated.
At the completion of 18 months, the intervention group parents demonstrated strong positive correlations between parent and child change in waist circumference ( = 0.409, < 0.001), triceps ( = 0.332, < 0.001), and subscapular ( = 0.292, = 0.002) skinfolds. There were no significant correlations between weight, health behaviors, eating, and exercise self-efficacy.
The results suggest that in the Southern United States low-income parents and their children with obesity are strongly correlated.

研究表明肥胖在家庭内部具有关联性，成功的干预措施需要涉及肥胖的父母和孩子双方。然而，关于父母与孩子之间肥胖程度和体重减轻的相似性，尤其是在社会经济地位较低、种族多样的家庭中，相关信息较少。
本研究的目的是检验参与一项为期18个月减肥计划的184名儿童及其184名父母从基线开始随时间变化的肥胖程度、体重、健康行为和自我效能之间的关系。仅在干预组内，针对每个基线后时间点，计算儿童在肥胖程度、体重、健康行为和自我效能方面（相对于基线）的变化与父母相应的基线变化之间的Pearson相关系数，以确定二元组之间的相关强度。
在18个月结束时，干预组父母在腰围（r = 0.409，P < 0.001）、肱三头肌皮褶厚度（r = 0.332，P < 0.001）和肩胛下皮褶厚度（r = 0.292，P = 0.002）方面的亲子变化之间呈现出强正相关。体重、健康行为、饮食和运动自我效能之间没有显著相关性。
结果表明，在美国南部，低收入肥胖父母及其子女之间存在很强的相关性。
