摘　　要：目的探究在校大学生日均千步当量与人体质量指数(BMI)的相关性,为控制大学生超重、肥胖提供可能的参考。方法以某医学校为例,先通过对在校大学生进行问卷调查,收集各因素进行方差分析和多元线性回归,确认日均千步当量与BMI的因果关系。考虑到其他因素,绘制相关性矩阵热力图进行相关性分析。进行多组实验,采用回归曲线拟合,以探讨日均千步当量在不同的增加程度与BMI的关系。最后采用对照研究实验,以进一步确认提高日均千步当量对BMI的影响。结果方差分析和多元线性回归分析结果表明,日均千步当量与BMI呈现因果关系。相关性分析表明,在众多因素中只有日均千步当量与BMI变化呈现强相关。回归曲线拟合在正常、超重、肥胖组中,曲线都呈下降趋势。在对照研究实验中,实验组与对照组的日均千步当量对BMI的影响在正常、超重、肥胖组差异均有统计学意义(P<0.05)。结论提高在校大学生的日均千步当量可有效降低体重和BMI值,在一定程度上控制超重和肥胖。Objective This study aims to explore the correlation between the daily average thousand-step equivalent and BMI among college students,providing potential references for controlling overweight and obesity among this population.Methods Taking a medical college as an example,we first conducted a questionnaire survey among college students to collect data on various factors for analysis of varianceand multiple linear regression,establishing the causal relationship between the daily average thousand-step equivalent and BMI.Taking into account other potential factors,a correlation matrix heat map was created for correlation analysis.Multiple sets of experiments were conducted using regression curve fitting to investigate the relationship between the daily average thousand-step equivalent and BMI at different increase levels.Finally,a controlled study was conducted to further validate the impact of increasing the daily average thousand-step equivalent on BMI.Results Among the factors investigated through variance analysis and multiple linear regression,a causal relationship was observed between the daily average thousand-step equivalent and BMI.Correlation analysis revealed a strong correlation between changes in the daily average thousand-step equivalent and BMI,outperforming other factors.Regression curve fitting demonstrated a downward trend in normal weight,overweight,and obese groups.In the controlled study,there were statistically significant differences(P<0.05)in the effects of the daily average thousand-step equivalent on BMI between the experimental and control groups across normal weight,overweigh,and obese group.Conclusion Increasing the daily average thousand-step equivalent among college students can effectively reduce body weight and BMI values,thereby controlling overweight and obesity to some extent.
