A study on the correlation between daily average thousand-step equivalent and BMI among students in a medical school
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 obe-sity among this population.Methods Taking a medical college as an example,we first conducted a question-naire 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 be-tween 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 anal-ysis revealed a strong correlation between changes in the daily average thousand-step equivalent and BMI,out-performing other factors.Regression curve fitting demonstrated a downward trend in normal weight,over-weight,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 over-weight and obesity to some extent.
