Another information about the newest newborns was used in the investigation from connections: delivery pounds, intercourse, Gap, host to delivery, scientific attendance from the beginning and type out of birth, especially CS.
Into parents we utilized age and you can knowledge categorized in the around three accounts (no. 1, supplementary and better) throughout the family studies.

The main consequences adjustable is actually birth pounds. I and offer particular outcomes for the new dichotomized, shorter educational but will utilized changeable LBW. To understand more about you’ll associations with assorted skout Jak funguje background details, linear regression activities were utilized. Since the certain mothers gave beginning so you’re able to more than one kid through the the newest several many years, i made use of several a few-height combined linear designs. The difference in the efficiency between this method and you may average regression is really slight. LBW are reviewed having fun with parallel several logistic models.
To learn the development over the years for delivery weight and beginning attributes we put easy linear regression from consequences to your independent go out varying. A few approaches for study out of associations between effects and you may record variables were utilized. In one we made use of most of the analysis in one single model. But not, relationships might change-over time and season-wise analyses was indeed plus familiar with decide to try character of such tendencies.
