Study On The Correlation Between Body Composition And Sleep Quality And Exercise Intervention In Obese College Student

Overweight or obesity is a serious threat to human health and is a common public health issue faced by countries around the world today,and a large number of studies in recent years have shown that poor sleep quality is more common in overweight and obese people.Being overweight or obese and poor sleep quality seriously affect people’s physical and mental health and daily life,and are potential factors for certain diseases.Studies have shown that there is a correlation between body composition and sleep quality,and that exercise interventions can have a certain impact.The purpose of this study is to provide a theoretical reference for promoting the health of obese college students by exploring the correlation between body composition and sleep quality and the impact of exercise intervention on the relationship.Research methods:This study uses literature method,questionnaire method,measurement method,experimental method and mathematical statistical method,taking college students of Shanghai Normal University as the research object,this study is divided into three levels,the first level: status survey,using the Pittsburgh sleep quality index(PSQI)to measure the sleep quality of the participants and obtain BMI related data,a total of874 valid questionnaires were recovered.The second level: large-sample anthropometry,a total of 413 college students were recruited to measure the body composition of the subjects through the principle of bioelectrical impedance,using the body composition tester to measure the body composition of the subjects,and explore the status and correlation between body composition and sleep quality.The third level:exercise intervention,through sleep quality and body composition measurement results 40 obese college students were selected as experimental subjects(inclusion criteria: BMI≥24,no major diseases and motor disorders,voluntarily participated in the whole process and were able to complete this experiment)and randomly divided into experimental group and control group.The experimental group underwent exercise interventions three times/week,60 minutes/time,for eight weeks,and the control group maintained its original living and exercise habits.Before and after the intervention,PSQI scale and body composition tester were used to measure the sleep quality and body composition of the test subjects.The results are as follows:1.1.The results of questionnaire survey analysis of 874 college students showed that BMI was positively correlated with subjective sleep quality,time of onset,sleep disorder and total sleep score(p<0.01),and with sleep duration and daytime dysfunction(p<0.05).2.The body composition indicators of 413 college students were measured and analyzed with various dimensions of sleep quality:(1)no significant correlation was detected between the waist-hip ratio and sleep quality indicators,but the scores of high waist-hip ratio in the dimensions of sleep onset time and sleep disorder were significantly higher than those of normal waist hip ratio of college students(P<0.05);(2)There was a significant positive correlation between body fat rate and daytime dysfunction(p<0.05),and a very significant positive correlation with sleep time,sleep disorder and total sleep score(p<0.01),and no significant difference was detected in all dimensions of PSQI in underly low body fat rate,standard,too high and obese college students(p>0.05).(3)Binary logistic regression analysis of body composition indicators and good and poor sleep quality showed that for each unit increase in body fat rate(OR=0.949,95% CI),the risk of poor sleep quality increased by 0.949 times,and the risk of poor sleep quality increased by 0.003 times for each unit increase in waist-hip ratio(OR=0.003,95% CI).3.(1)There were no significant differences in the dimensions of sleep quality before the experiment in different groups,and there were significant differences in sleep onset time,sleep time,sleep disorder,daytime dysfunction and total sleep score after the experiment(p<0.01);There were no significant differences before and after the body composition experiment between the different groups.(2)The changes in sleep quality score in the experimental group were significantly positively correlated with changes in body weight,BMI,defatted body mass,and muscle mass(p<0.05),and significantly positively correlated with fat mass,body fat rate,extracellular fluid and subcutaneous fat content(p<0.01).In the control group,there was a significant positive correlation between sleep efficiency and body weight,BMI,muscle mass,and subcutaneous fat content(p<0.01),and the dimension of daytime dysfunction was negatively correlated with visceral fat content(p<0.01).The research conclusion is as follows:1.The higher the BMI,the higher the probability of having sleep problems.2.There is no significant correlation between the indicators of waist-hip ratio sleep quality;The higher the body fat rate,the higher the detection rate of poor sleep quality.3.Aerobic combined resistance training can effectively promote sleep onset,sleep time,sleep disorders and daytime dysfunction,and is an effective way to improve sleep quality;At the same time,it can effectively promote weight loss.
