BACKGROUND/OBJECTIVES: There is a lack of research exploring the effects of Roux-en-Y gastric bypass (RYGB) surgery on the patient's family's eating behaviour and food choices. The aim of the current study was to investigate changes in partners' and children's eating behaviour and food choices following maternal RYGB.
SUBJECTS/METHODS: Sixty-nine women and their families were recruited from RYGB waiting lists at five Swedish surgical clinics. Data were collected during home visits 3 months before and 9 months after RYGB. Anthropometrical measures were taken, the adults completed the Three-Factor Eating Questionnaire and the children completed the Children's Eating Attitudes Test (ChEAT). All participants also completed a short food frequency questionnaire.
Changes in scores were analysed using paired t-tests for unadjusted estimates or linear regression models with robust variance (General Estimating Equations) in order to enable age- and sex-adjusted estimates for the children. There were no meaningful differences in the partners' eating behaviour or food choices. The boys, but not the girls, improved their ChEAT scores, as did the overweight/obese children in comparison with the normal-weight children. The boys, unlike the girls, also decreased their intake of soft drinks, as did the normal-weight children when compared with the overweight/obese children.
No clear-cut changes were found in partners' eating behaviour and food choices. Eating attitudes and soft drinks intake were improved among boys but not among girls. Differing modelling behaviour may partially explain these findings, but available data did not allow us to understand the underlying mechanisms.
背景/目的：缺乏关于胃旁路手术（RYGB）对患者家庭饮食行为和食物选择影响的研究。本研究的目的是调查母亲接受RYGB手术后其伴侣和孩子的饮食行为及食物选择的变化。
对象/方法：从瑞典五家外科诊所的RYGB候诊名单中招募了69名女性及其家人。在RYGB手术前3个月和术后9个月进行家访时收集数据。测量人体测量指标，成年人完成三因素饮食问卷，儿童完成儿童饮食态度测试（ChEAT）。所有参与者还完成了一份简短的食物频率问卷。
使用配对t检验分析分数变化以获得未调整的估计值，或使用具有稳健方差的线性回归模型（广义估计方程），以便能够对儿童进行年龄和性别调整后的估计。伴侣的饮食行为或食物选择没有显著差异。男孩（而非女孩）的ChEAT分数有所提高，超重/肥胖儿童与正常体重儿童相比也是如此。与女孩不同，男孩的软饮料摄入量也有所减少，正常体重儿童与超重/肥胖儿童相比也是如此。
未发现伴侣的饮食行为和食物选择有明显变化。男孩的饮食态度和软饮料摄入量有所改善，但女孩没有。不同的榜样行为可能部分解释了这些发现，但现有数据无法让我们理解其潜在机制。
