Correlation between nutritional status and mental sub-health among Chinese adolescents

Abstract

Objective To explore the correlation between different nutritional status and mental sub-health of Chinese adolescents, and provide reference for improving the physical and mental health of Chinese adolescents. Methods A total of 16 545 adolescents (13-22 years old) were selected by random overall sampling method in six major administrative regions in China.The psychological part of the Multidimensional Sub-health Questionnaire of Adolescents (MSQA) was used for mental sub-health test. Chisquare test and Logistic regression analysis were used to analyze and compare the relationship between different nutritional status and mental sub-health. Results The overall detection rate of mental sub-health status in the adolescents with normal BMI group was 18.5%, while those in the lean, overweight and obese groups were 22.3%, 38.7%, and 44.7%, respectively, which were significantly different from those in the normal BMI group (χ 2 =478.68, P <0.05). After adjusted for gender and age, the Logistic regression model showed that compared with those with normal BMI, those who were thin ( OR = 1.19, 95% CI = 1.09-1.30), overweight ( OR =2.76, 95% CI = 2.47-3.09) and obese ( OR = 3.43, 95% CI =2.83-4.15) had increased risk of mental sub-health. Conclusion The nutritional status of Chinese adolescents in significantly related to mental sub-heatlh, hose who are underweight, overweight and obese have significantly higher risks of mental sub-health than those who are normal.Improvement of nutritional status of adolescents is beneficial to healthy adolescent development. 【摘要】 目的 探究中国青少年营养状况与心理亚健康之间的相关性, 为中国青少年身心健康发展提供参考。 方法 在 中国华东、华北、中南、西北、西南和东北地区, 分别采用分层随机整体抽样法抽取 16 545 名 13~22 岁青少年, 采用青少年 亚健康多维评定问卷 (Multidimensional Sub-health Questionnaire of Adolescents, MSQA) 中的心理问卷进行心理亚健康测试。采用 χ 2 检验及 Logistic 回归分析对营养状况与心理亚健康的关系进行分析。 结果 青少年体质量指数 (BMI)正常组的心 理亚健康状态总体检出率为 18.5%, BMI 消瘦组、超重组和肥胖组分别为 22.3%, 38.7% 和 44.7%, 不同营养状况青少年的 心理亚健康状态检出率差异有统计学意义 (χ 2 =478.68, P <0.05)。Logistic 回归模型在调整了性别和年龄后, 相对于BMI正 常者, 消瘦者 ( OR =1.19,95% CI =1.09〜1.30)、超重者 ( OR = 2.76,95% CI =2.47〜3.09) 和肥胖者 ( OR = 3.43,95% CI =2.83 〜 4.15) 发生心理亚健康的风险增加。 结论 中国青少年营养状况与心理亚健康相关, 消瘦、超重和肥胖者发生心理亚健康 的风险均高于正常者, 改善青少年营养状况将有利于青少年身心健康发展。
