A comparison will be made between mothers who smoked before pregnancy, mothers who smoked before pregnancy and during the first trimester and mothers who smoked before pregnancy, 1st and 3rd trimester of their pregnancy. The control variable in our study will include mother’s marital status and education to differentiate any changes on mother’s decision about smoking and birth outcome. We will then assess infant’s birth weight as it relates to these three categories and identify if smoking is or is not associated with low birth weight and or preterm infants. This will be done by selecting randomly, a sample size of 1000 babies born in the year 2013 and evaluate their birth weight and gestation age as it relates to maternal smoking habits. This will be shown in the excel spreadsheet …show more content…
According to the Center of Disease Control and Prevention premature birth affects more than 450,000 infants in the United States in 2012, suggesting that for every 9 infants born 1 will be premature and has it pertains to low birth weight, about 315,832 infants were born below 2500 grams in the same year. The good news about these two trends is that over the past 20 years’ data collected by the National Vital Statistics have shown a downward consistent trend in the US birth weight and preterm distribution. A study completed by The Center of Disease Control and Prevention, data collection through The Pregnancy Risk Assessment Monitoring System showed that smoking during pregnancy varied by several characteristic, some included, education level, marital status and maternal age. The findings also suggested that there was a significant decline between 2000-2010 in the prevalence of smoking before, during, and after pregnancy, in the states of Colorado, Illinois, New Jersey, New Mexico, New York City, Washington, Wisconsin, and Wyoming (Tong, Dietz, Morrow, D¿Angelo, Farr, Rockhill, & England,
