Food addiction (FA) is associated with a higher body mass index -score (BMIZ) in children and adolescents; however, whether these two aspects evolve interdependently remains unknown. This study aimed to address this question using a cross-lagged study.
Weight status, including BMIZ, fat content (FC), and visceral fat level (VFL), was determined in 880 children and adolescents (mean age = 14.02 years [range = 8.83-17.52 years]) at two-time points with an interval of 6 months. FA was characterized using the Chinese version of the dimensional Yale Food Addiction Scale for Children 2.0. Furthermore, FC and VFL were measured using direct segmental multi-frequency bioelectrical impedance analysis at each time point.
Higher FA was associated with increased BMIZ, FC, and VFL ( < 0.05). FA at T0 could predict increased FC at T1 ( < 0.05). The characteristics of females, primary students, and living in urban areas may aggravate the adverse effect of FA on weight status over time and age, particularly the increased VFL in participants aged > 14 years.
Children and adolescents with a high FA level were at risk for weight gain attributed to increased FC, and the adverse effect could be aggravated with time and age. Novel FA-targeting interventions may help mitigate the risk of getting obesity.
食物成瘾（FA）与儿童和青少年的体重指数得分（BMIZ）较高有关；然而，这两个方面是否相互依存发展尚不清楚。本研究旨在使用交叉滞后研究来解决这个问题。
在两个时间点对 880 名儿童和青少年（平均年龄=14.02 岁[范围=8.83-17.52 岁]）的体重状况进行了评估，包括 BMIZ、体脂肪含量（FC）和内脏脂肪水平（VFL），两次测量间隔为 6 个月。使用儿童 2.0 版维度耶鲁食物成瘾量表的中文版来描述 FA。此外，在每个时间点使用直接分段多频生物电阻抗分析测量 FC 和 VFL。
较高的 FA 与 BMIZ、FC 和 VFL 的增加有关（<0.05）。T0 时的 FA 可以预测 T1 时 FC 的增加（<0.05）。女性、小学生和居住在城市地区的特征可能会随着时间和年龄的推移加重 FA 对体重状况的不利影响，尤其是在年龄>14 岁的参与者中增加 VFL。
具有高 FA 水平的儿童和青少年体重增加的风险更高，归因于 FC 的增加，并且随着时间和年龄的推移，这种不利影响可能会加剧。针对 FA 的新干预措施可能有助于降低肥胖风险。
