Thus, the number of subjects were reduced to 70. The group was divided into two: ( High Glycemic Index) HGI and LGI ( Low Glycemic Index ) group. However, three members of the LGI group withdrew since two of them cannot comply with the nutritional intake while the other one gave birth. Therefore, the total number of subjects were reduced to sixty-seven. Towards the end, only sixty-two women completed the study. Considerably, this figure is statistically significant since this is composed of the pregnant women at that time. In fact, sample size is one of the strengths of this study which contributes to the studies’ reliability.
Since obstetrics outcomes are the parameters for evaluation of the results, pregnant females were obviously used for this study. Considerations for inclusion in the study are the following: aged 21–40 y, had a singleton pregnancy, were between 12 and 16wk.gestation, were nonsmokers, and had no more than 1 alcoholic drink each day. All participants must fit into these requirements. Consent was properly sought before conducting the baseline trial. The study was done 5 times between 16 weeks gestation and delivery. Considerably, it is a long period of time since the women’s pregnancy were completely monitored until the time they gave birth. The whole study lasted for about 6 months since the women were at least 3 months pregnant at the time the study was conducted. Fetal size is the indicator in the principal findings, thus this meant that the study continued until the time the women gave birth.
The study’s primary aim “ was to assess effects of inclusion of high- or low-GI carbohydrate-rich foods on the outcomes of pregnancy. For this purpose the principal findings were indicators of fetal size”. In fact, the article mentioned that two studies on glucose intolerant women were done before but gave conflicting findings. This is the first study that
