An observational study titled “Alcohol intake among first-time moms and the risk of preterm birth: a cohort study” was conducted on mothers residing in Norway. Using various techniques, this study collected data on alcohol intake from prospective observational Norwegian Mother and Child Cohort Study questionnaire responses at 15 weeks of pregnancy. Babies born before 37 weeks were designated preterm births, which also collected data (Dale et al., 2018). These figures were obtained from the Norwegian Medical Birth Registry.

Data on first-time mothers’ experiences and alcohol consumption before a specific week of gestation is being gathered and analyzed. Besides, the researchers examined data collected after the child was born to determine what impacts alcohol induced on them. This study also evaluated the population and data. They focused on standard ultrasounds performed between weeks 17 and 18 of pregnancy (Dale et al., 2018). Additionally, they considered how many alcoholic beverages the mother consumed before the third month of pregnancy. They employed graphs and charts to display the amount and frequency of alcohol consumption.

One of the study’s potential flaws was how the charts were divided between pregnant drinkers and nonsmokers. It ought to have been divided into drinkers and non-drinkers. At the same time, this research was unrelated to drinking. The researchers’ viewpoints may become skewed due to categorizing them in this way. The mothers involved in this study represent all significant demographic groups (Dale et al., 2018). After undergoing a conventional ultrasonography assessment at a nearby medical facility, participants were selected for the study by postal invitation. Members were recruited for the study through a postal greeting after completing a routine ultrasonography assessment at a nearby medical facility.
