Because of the highest incidence out of over weight and you will carrying excess fat seen (bigger than ten%) inside analysis, employing logistic regression models might bring about an enthusiastic overestimation of one’s contacts between this type of disease outcomes and possible chance products . Thus, to assess this type of connectivity way more precisely, we functioning a Poison regression study that have people sampling modifications to own new computation away from Prevalence Ratios (PRs) . The analyses was basically held which have Stata fourteen.step one (StataCorp, School Channel, Tx, USA)
Efficiency
There had been 2788 children (%) that have complete details about decades, intercourse, lbs and you can height as part of the analysis.
