Explanation / Answer

(1) Study summary:

            The article is based on investigating the effect of smoking in pregnant mother's and its effect on the infants. The study shows that maternal smoking during pregnancy results in the risk of rapid weight gain in offsprings in early infancy. The essence of the study is to determine the restriction in intrauterine growth of the foetus, leading to low birth weight and the effects of smoking in the near future of the infants.The study objective/research question

(2) Primary exposure(s) and outcome(s) of interest:

Primary exposure : smoking pregnant mother's and ex-smokers.

Outcomes: The results of the study showed an increased risk of rapid weight gain (RWG) in infants whose mothers have been exposed to smoking during pregnancy. The number of cigarettes smoked increased the RWG risk.

(3) Identification of study design:

            The study was designed on pregenant mothers who were non-smokers, ex-smoker's and the women who smoked during pregnancy. Nevertheless, the children of the women who smoked during their pregnany had RWG and were found to have the after-math effect of pregnancy like cardiovascular disorders.

(4) Description of study population and the sampling/selection process:

            The study was perfomed on 8398 individuals who were non-smokers, 1524 who were ex-smokers, and 511 who smoked during pregnancy (1-5 cigarettes/day).
