Objective

Comorbidity between substance use disorders and eating disorders is common and related to severity of psychopathology. Parents’ eating disorder or substance use disorder have been examined independently and appear to be related to psychopathology in their children. However, no prior work has examined whether co-occurring substance use and eating disorder behaviors in parents relate to eating-disorder psychopathology and weight in their children.

Method

Participants (N = 435) were parents who completed an online cross-sectional survey. Parents reported their personal substance use and eating-disorder behaviors. Relationships between parental substance use (SUD), parental binge eating (ED), and co-occurring parental substance use and binge eating (SUDxED) with child eating-disorder psychopathology and weight were examined using linear regression. Parent age and sex, child age and sex, parent impulsivity and parent depression scores were included as covariates in analyses.

Results

Greater severity of co-occurring parental SUDxED behavior was associated with greater child eating-related psychopathology, including child binge eating and child purging. Additionally, greater parental binge eating (ED) alone was associated with greater child binge eating and overeating. Parental SUD and/or ED behavior were not related to child weight. Child age did not moderate relationships between parent SUDxED behaviors and child binge eating or overeating.

Discussion

Overall, parents with greater co-occurring substance use and eating disorder behaviors had children with more severe eating-disorder psychopathology. Clinicians working with families, and those seeking to prevent pediatric eating-related problems, should consider assessing and addressing parents’ psychopathology to improve prevention and treatment efforts.

双重麻烦？父母物质使用和饮食行为与儿童饮食失调的关联

 客观的

物质使用障碍和饮食失调之间的共病很常见，并且与精神病理学的严重程度有关。父母的饮食失调或物质使用障碍已经过独立检查，似乎与孩子的精神病理学有关。然而，之前的研究还没有研究过父母同时发生的物质使用和饮食失调行为是否与饮食失调精神病理学和孩子的体重有关。

 方法

参与者 ( N = 435) 是完成在线横断面调查的家长。家长报告了他们的个人药物使用和饮食失调行为。使用线性回归检查父母物质使用（SUD）、父母暴食（ED）以及同时发生的父母物质使用和暴食（SUDxED）与儿童饮食失调精神病理学和体重之间的关系。父母年龄和性别、儿童年龄和性别、父母冲动和父母抑郁评分作为协变量纳入分析。

 结果

父母同时发生的 SUDxED 行为的严重程度与儿童饮食相关的精神病理学相关，包括儿童暴食和儿童净化。此外，仅父母暴食（ED）的增加与儿童暴食和暴饮暴食的增加有关。父母的 SUD 和/或 ED 行为与儿童体重无关。儿童年龄并未调节父母 SUDxED 行为与儿童暴饮暴食或暴饮暴食之间的关系。

 讨论

总体而言，同时发生药物滥用和饮食失调行为的父母，其孩子的饮食失调精神病理学更为严重。与家庭一起工作的临床医生以及寻求预防儿科饮食相关问题的临床医生应考虑评估和解决父母的精神病理学问题，以改善预防和治疗工作。
