Mental health disorders are one of the most important and increasing health problems in the youth of today's societies. Some dietary intake and body mass status are factors that affect mental health. This study aimed to investigate the relationship between the intake of branched-chain amino acids (BCAAs) and aromatic amino acids (AAAs) and anthropometric and dietary inflammatory indices with mental health, including depression, anxiety, and stress.
In this case-control study, the data of 138 teenage girls aged 13-18 years were collected. Three-day 24-hour food recall and standard anthropometric methods were used to calculate the dietary inflammation intake score of normal and energy-adjusted diets. Mental health disorders were diagnosed by the DASS-21 questionnaire. Statistical analysis used Student's -test, correlation, and multiple regression were used to analyze the data based on the study's statistical requirements.
Based on the findings, 59 (42%) of the girls had mental disorders, and 79 (58%) were healthy. The average weight of stressed people was significantly higher than that of healthy people, and the BMI of anxious people was significantly higher than that of nonanxious people ( < 0.05). A significant positive correlation was found between stress and weight and energy intake. Additionally, there was a significant negative correlation between BCAAs and mental health. The average intake of BCAAs was significantly lower in patients ( = 0.01). The trend analysis showed significantly lower BCAA levels among the 4 quartile of mental disorders. No significant relationship was observed between DII, AAA, and anthropometric indices. After adjustment of the results, no relationship was observed between mental health and the studied factors.
BCAA might be related to mental health. Further studies in different age and sex groups are highly recommended.
心理健康障碍是当今社会青少年中最重要且日益增多的健康问题之一。一些饮食摄入和身体质量状况是影响心理健康的因素。本研究旨在调查支链氨基酸（BCAAs）和芳香族氨基酸（AAAs）的摄入量与人体测量指标及饮食炎症指标与心理健康（包括抑郁、焦虑和压力）之间的关系。
在这项病例对照研究中，收集了138名13 - 18岁少女的数据。采用三日24小时食物回顾法和标准人体测量方法来计算正常饮食和能量调整饮食的饮食炎症摄入评分。通过DASS - 21问卷诊断心理健康障碍。根据研究的统计要求，使用学生t检验、相关性分析和多元回归分析数据。
根据研究结果，59名（42%）女孩患有精神障碍，79名（58%）健康。有压力人群的平均体重显著高于健康人群，焦虑人群的BMI显著高于非焦虑人群（P < 0.05）。压力与体重和能量摄入之间存在显著正相关。此外，BCAAs与心理健康之间存在显著负相关。患者的BCAAs平均摄入量显著较低（P = 0.01）。趋势分析显示，在精神障碍的第4四分位数中，BCAA水平显著较低。未观察到饮食炎症指数（DII）、AAAs与人体测量指标之间存在显著关系。对结果进行调整后，未观察到心理健康与所研究因素之间存在关系。
BCAA可能与心理健康有关。强烈建议在不同年龄和性别组中进行进一步研究。
