Study on the relationship between mental health and overweight, obesity, different sex among junior middle school students

目的 了解超重、肥胖与男女初中学生生活满意度、抑郁、焦虑、自我意识水平之间的相关性。方法 对象为合肥市某中学1818名初一和初二学生,用多维学生生活满意度量表、流行病学调查中心用抑郁量表、特质焦虑量表和儿童自我意识量表及相应的评价标准进行心理健康评定,同时测量身高、体重,计算体重指数（BMI）值。参考中国儿童青少年超重和肥胖筛查BMI值分类标准进行分组,分析男女生及体重正常、超重、肥胖组学生心理健康状况的差异以及男女生BMI与4个量表评分的相关性。结果 男生超重和肥胖检出率（21．5%和7．7%）显著高于女生（8．0%和2．8%）。体重正常组生活满意度评分的性别差异有统计学意义（P=0．002）,超重组抑郁评分的性别差异有统计学意义（P=0．046）。在女生中,体重正常、超重和肥胖3组的抑郁、特质焦虑和自我意识评分的差异均有统计学意义（P＜0．05）,肥胖组抑郁和焦虑评分显著高于体重正常组（P=0．012和P=0．035）,肥胖组自我意识评分低于体重正常组（P=0．014）,超重组抑郁评分高于体重正常组（P=0．025）。结论 超重、肥胖检出率女生低于男生,但女生超重和肥胖者心理健康水平与体重正常者的差别较男生明显。

Objective To examine the relationships between overweight, obesity and indices as satisfaction of,life, trait anxiety, depression, self concept etc. in male and female junior middle school students. Methods A questionnaire survey was administered to 1818 participants in a middle school in Hefei city, Anhui province. This contents of survey would include Multidimensional Students＇ Life Satisfaction Scale （MSLSS）, Center for Epidemiologic Studies Depression Scale（CES-D）, Trait Anxiety Inventory （TAI）, and Piers-Harris Children＇s Self Concept Scale （PHSCS）. Anthropometric measures were taken together with the calculation of body mass index （BMI）. The students were divided into normal-weight, overweight and obesity groups by BMI separate criteria. Gender differences of mental health status and group differences of mental health among normal-weight, overweight obesity students were analyzed. Relationships between BMI and the scores of MSLSS, CES-D, TAI, PHSCS were estimated among boys and girls respectively. Results The prevalence rates of overweight and obesity of boys （21.5 %, 7.7 % ） were significantly higher than in girls （8.0 %, 2.8 % ）. Difference of the MSLSS scores in gender was significant among normal-weight group （P = 0. 002）. The difference of the CES-D scores in gender was significant among overweight group （ P = 0. 046）. There were significant group differences of the CES-D scores, TAI scores, and PHSCS scores among normal-weight, overweight and obese girls （P 〈 0.05）. Both the CES-D score and TAI score of obese girls were higher than normal-weight girls （P = 0.012 and P = 0. 035）. The PHSCS score of obese girls was lower than normal-weight girls （ P = 0. 014 ） and the group difference of the CES-D score was also significant between overweight and normal-weight girls （P = 0. 025）. Conclusion Both prevalence rates of overweight and obesity of boys were higher than that in girls. Nevertheless, level of mental health level among girls with overweight and obesity were lower than that in boys.
