Obesity is a multifactorial chronic disease influenced by behavioral, environmental, genetic, and psychological factors. One primary determinant of childhood obesity is the presence of dietary factors commonly acquired through the shared home food environment, which parents can greatly influence. Thus, the present study examined the similarity in diet quality between children or adolescents with obesity and their mothers. We analyzed baseline data collected from the Intervention for Children and Adolescent obesity via Activity and Nutrition study. Seventy mother-offspring dyads were identified, which included children and adolescents with obesity aged 8-16 years and their mothers living in Seoul and Gyeonggi Province, South Korea. Food or nutrient intake and diet quality were evaluated from 3-day food records. Childhood obesity was defined as body mass index ≥ 95th percentile based on the 2007 Korean National Growth Charts. No significant difference was observed in the diet quality score between children with obesity and their mothers. However, correlation coefficients between mothers and their children's total Diet Quality Index-International (DQI-I) score (r = 0.30) and subcategories, such as variety (r = 0.29), adequacy (r = 0.43), moderation (r = 0.45), and overall balance (r = 0.30), were positively correlated (p < 0.05). Linear regression analysis of the influence of maternal diet quality on offspring diet quality revealed that the maternal DQI-I score influenced the offspring's DQI-I score, consistent with our prediction. Further studies with larger and more representative samples are needed to confirm the applicability of our findings to all children and adolescent populations.

肥胖是一种受行为、环境、遗传和心理因素影响的多因素慢性疾病。儿童肥胖的一个主要决定因素是通常通过家庭共享饮食环境获得的饮食因素的存在，而父母对此有很大影响。因此，本研究调查了肥胖儿童或青少年与其母亲饮食质量的相似性。我们分析了通过活动和营养研究收集的儿童和青少年肥胖干预的基线数据。确定了70对母婴二元组，其中包括8至16岁的肥胖儿童和青少年及其居住在韩国首尔和京畿道的母亲。根据3天的饮食记录评估食物或营养摄入量及饮食质量。根据2007年韩国国家生长图表，儿童肥胖定义为体重指数≥第95百分位数。肥胖儿童与其母亲的饮食质量得分未观察到显著差异。然而，母亲与其子女的总饮食质量指数-国际（DQI-I）得分（r = 0.30）以及各子类别之间的相关系数，如多样性（r = 0.29）、充足性（r = 0.43）、适度性（r = 0.45）和总体平衡（r = 0.30）呈正相关（p < 0.05）。母亲饮食质量对后代饮食质量影响的线性回归分析表明，母亲的DQI-I得分影响后代的DQI-I得分，与我们的预测一致。需要用更大且更具代表性的样本进行进一步研究，以确认我们的研究结果对所有儿童和青少年群体的适用性。
