【摘要】：肥胖在当今社会日趋普遍,已成为了影响全世界的公共健康问题。肥胖不但会引起各种生理疾病,且会对大脑认知功能造成负面影响。青少年时期是认知功能发展的关键时期,此阶段的认知功能尤为容易受到肥胖的损害,以致影响学业成绩甚至降低个体的生活质量,为此积极研究青少年肥胖与认知功能的关系刻不容缓。采用Flanker任务探究肥胖青少年与正常体质量青少年在基本认知功能及高阶认知功能上的差异及特点,并进一步运用相关分析探究身体质量指数(BMI)与2种认知功能的关系。结果显示:(1)无论在一致刺激条件还是不一致刺激条件下,肥胖组的反应时都显著慢于正常体质量组,P0.01,这表明肥胖青年无论在基本认知功能还是高阶认知功能上的表现都差于正常体质量青少年;(2)BMI与一致刺激条件(r=0.45)及不一致刺激条件下的反应时都呈显著正相关(r=0.51),P0.01,表明个体越肥胖,对基本认知功能及高阶认知功能的负面影响越大。结论:肥胖青少年在基本认知功能及高阶认知功能上都差于正常体质量青少年,BMI与认知功能呈负相关。
[Abstract]:Obesity is becoming more and more common in today's society and has become a public health problem affecting the world. Obesity not only causes a variety of physiological diseases, but also has a negative impact on the cognitive function of the brain. Adolescence is a critical period for the development of cognitive function, which is particularly vulnerable to obesity, which affects academic performance and even reduces the quality of life of the individual. Therefore, it is urgent to study the relationship between adolescent obesity and cognitive function. The differences and characteristics of basic cognitive function and higher-order cognitive function between obese adolescents and normal body weight adolescents were investigated by using Flanker task, and the correlation analysis was used to explore the relationship between body mass index (BMI) and two cognitive functions. The result shows that under the condition of consistent stimulus or inconsistent stimulus, The response time of obesity group was significantly slower than that of normal body mass group (P0.01), which indicated that obese young people had lower basic cognitive function and higher cognitive function than normal body mass adolescents with BMI and consistent stimulus condition (0.45). There was a significant positive correlation between the response time and the response time under the stimulation condition, which indicated that the individuals were more obese, The negative effect on basic cognitive function and higher cognitive function is greater. Conclusion: there is a negative correlation between BMI and cognitive function in obese adolescents compared with normal body mass adolescents in basic cognitive function and higher cognitive function.
