| Objective:A total of 1,200 junior high school students from four middle schools in Hohhot's Huimin District,Saihan District,Xincheng District and Yuquan District were selected,and a questionnaire survey was used to investigate the lifestyle of junior high school students(eating habits,sleep status,physical exercise,learning and entertainment,tobacco and alcohol health awareness),on-site testing of physical health indicators,and analysis of the impact of lifestyle on students'physical health.Method:1.Target:1200 junior high school students from Hohhot Huimin Middle School,No.39 Middle School,No.34 Middle School and Tumut School in Inner Mongolia Autonomous Region were selected as the respondents.2.Methods:The Questionnaire on Physical Health and Lifestyle of Junior High School Students was used to collect lifestyle-related data of junior high school students.In November 2021,I entered the school to conduct a questionnaire survey with a total of 30 questions,including 5dimensions.The test indicators,test methods and evaluation methods are tested and evaluated in accordance with the National Student Physical Health Standards.Using SPSS28.0 software,the counting data between genders and grades is checked by chi-square.The correlation between lifestyle and physical health was analyzed by Pearson correlation,and the effects of lifestyle dimensions on physical health were analyzed by regression,and the significance level was set at P<0.05.Outcome:(1)The total lifestyle score:There was no difference between the sexes in the total lifestyle scores(P>0.05);the total lifestyle scores in the first grade(109.12±11.18)were higher than those in the second grade(108.01±11.17)and the third grade(105.68±11.10)(F=9.14,P<0.01).(2)Among the five dimensions of lifestyle:Eating habits(24.14±3.64 points)and tobacco and alcohol health awareness(24.06±2.59points)scored the highest,learning and recreation(18.15±4.42 points)scored the lowest,physical exercise habits(21.83±2.54 points)and sleep status scores(19.47±3.90 points)were average.(3)Obesity detection rate:The obesity detection rate was higher in boys than in girls(P<0.01),and there was no difference in obesity detection rate between grades(P=0.732).(4)Lung capacity:The lung capacity score(74.25±20.55 points)of the junior high school girls was lower than that of the first grade(82.44±14.09 points)and the second grade(80.44±14.08 points)(F=13.288,P<0.01).(5)Physical fitness level:Girls(92.1%)have a higher pass rate of physical fitness level than boys(71.4%)(P<0.01);there is no difference in pass rate between grades(P=0.201).(6)The correlation between lifestyle and physical health:Students with high scores in lifestyle and five dimensions also had a high level of physical fitness(P<0.01).(7)The influence of lifestyle on physical health:Through the correlation study between lifestyle and physical health,it was found that the lifestyle was excellent,and its physical health score was relatively high,and the correlation coefficient between junior high school students'lifestyle and physical health was 0.427(P<0.01);the five dimensions were used as independent variables,and the physical health was used as the dependent variable for regression analysis,when the five independent variables were introduced into the regression equation,R~2was the largest,R~2was 0.360 in the regression equation for junior high school students'lifestyle and physical health,and the expression of the regression equation was:y=-7.730+1.243X1+0.580X2+0.837X3+0.547X4+0.345X5,where X1is a physical exercise habit,X2is a study and entertainment,X3is a health awareness of tobacco and alcohol,X4is a dietary habit,and X5is a sleep condition.R~2is 0.332 in the regression equation for boys'lifestyle and physical health,and R~2is 0.445 for girls in the regression equation for lifestyle and physical health.Conclusion:(1)Lifestyle(eating habits,sleep conditions,physical exercise habits,learning and entertainment leisure,tobacco and alcohol health awareness)the more healthy people,the higher the level of physical health,a good lifestyle has a promoting effect on the level of physical health.(2)The lifestyle of junior high school students affects physical health,and the lifestyle of girls has a greater impact on physical health than boys.(3)Among the five dimensions of lifestyle,physical exercise habits have the greatest impact on physical health levels,and sleep conditions have the least impact. |
