Available evidence indicates that junk foods, defined as unhealthy foods with high-calorie and low-nutrient value, negatively affect mental and metabolic health of children. This study aimed to conduct a meta-analysis to clarify the association between junk food consumption and psychological distress in children and adolescents. A systematic literature search of relevant documents published in PubMed, Web of Science, and SCOPUS was conducted up to 2022. All observation studies which assessed association of junk foods and psychological distress in children and adolescents were included. Random-effect model was used to pool odds ratio (OR) and 95% confidence interval (CI) from individual studies. Subgroup meta-analysis was performed based on junk foods categories (sweet drinks, sweet snacks and snacks). Data of 17 included articles on junk foods consumption in relation to depression, stress, anxiety, sleep dissatisfaction and happiness in children and adolescents were included in this systematic review. According to random effect model, the pooled OR in the highest vs. the lowest category of junk foods was 1.62 (95% CI: 1.35-1.95) for depression, 1.34 (95% CI: 1.16-1.54) for stress, 1.24 (95% CI: 1.03-1.50) for anxiety, 1.17 (95% CI: 1.05-1.30) for sleep dissatisfaction and 0.83 (95% CI: 0.75-0.92) for happiness. In subgroup meta-analysis, there were significant associations between different types of junk foods and psychological distress ( < 0.05). This meta-analysis showed that junk foods consumption was associated with increased odds of psychological distress in children and adolescents. These findings support the current recommendation of decreasing junk foods intake.
现有证据表明，垃圾食品被定义为高热量、低营养价值的不健康食品，会对儿童的心理和代谢健康产生负面影响。本研究旨在进行一项荟萃分析，以阐明儿童和青少年食用垃圾食品与心理困扰之间的关联。截至2022年，我们对发表在PubMed、科学网和Scopus上的相关文献进行了系统检索。纳入了所有评估儿童和青少年垃圾食品与心理困扰之间关联的观察性研究。采用随机效应模型汇总各研究的比值比（OR）和95%置信区间（CI）。基于垃圾食品类别（甜饮料、甜零食和零食）进行亚组荟萃分析。本系统评价纳入了17篇关于儿童和青少年食用垃圾食品与抑郁、压力、焦虑、睡眠不满和幸福感关系的文章。根据随机效应模型，垃圾食品摄入量最高组与最低组相比，抑郁的合并OR为1.62（95%CI：1.35-1.95），压力为1.34（95%CI：1.16-1.54），焦虑为1.24（95%CI：1.03-1.50），睡眠不满为1.17（95%CI：1.05-1.30），幸福感为0.83（95%CI：0.75-0.92）。在亚组荟萃分析中，不同类型的垃圾食品与心理困扰之间存在显著关联（<0.05）。这项荟萃分析表明，儿童和青少年食用垃圾食品与心理困扰几率增加有关。这些发现支持了目前减少垃圾食品摄入量的建议。
