Statistical actions
BMI-for-many years score try computed utilizing the Whom 2007 Stata bundle. That one are revealed in detail and you can composed someplace else . The fresh new imply, fundamental meaning (SD), median, and you will interquartile interval (IQI) have been computed on their own for each gender.

For this reason, to evaluate these types of relationships more accurately, i operating a good Poison regression studies with party testing adjustment to have the fresh new formula out of Incidence Ratios (PRs) . The analyses was held that have Stata 14.step 1 (StataCorp, College Channel, Tx, USA)
Performance
There had been 2788 students (%) which have accomplished information on many years, gender, lbs and you will level included in the studies.
