Researchers asked pregnant women if they are currently smoking during this pregnancy and afterwards followed them through childbirth to test the association between smoking during pregnancy and stillbirth. Some smokers reported not smoking, resulting in some who were exposed being labeled as not exposed.

  1. What kind of bias is this?
  2. Do you think false reporting is more likely in one of the two groups (stillbirth, live birth) or equally likely?

Is smoking during pregnancy associated with premature births? To investigate this question, researchers selected a random sample of 107 pregnant women who were smokers. The average pregnancy length for this sample of smokers was 264 days. From a large body of research, it is known that length of human pregnancy has a standard deviation of 16 days. The researchers assume that smoking does not affect the variability in pregnancy length. Find the 99% confidence interval to estimate the length of...

Pregnant women were recruited during their first trimester to study the relationship between chocolate consumption during pregnancy and risk of preeclampsia (pregnancy-induced hypertension). They were interviewed about chocolate consumption, age, race, education, smoking, body mass index, and previous pregnancy history. Participants were re-interviewed after delivery to obtain information on chocolate consumption during the third trimester of pregnancy. In addition, umbilical cord blood was collected at the time of delivery and measured for concentration of theobromine (the major metabolite of chocolate)....

Medical researchers are concerned about the association between maternal smoking habits and the need for caesarian section during birth. Suppose the researchers gather 423 expecting mothers in their third trimester and follow them through pregnancy to examine the incidence of caesarian. Suppose out of the 102 mothers that reported smoking cigarettes at least once during pregnancy, 59 of them were referenced to have needed caesarian intervention during delivery, while 73 of the mothers with no smoking history reportedly needed the...

During 1938–1971, physicians in the United States prescribed diethylstilbestrol (DES) to pregnant women to prevent miscarriages and avoid other pregnancy problems. At the time, physicians thought DES was safe and would prevent miscarriages and pre-term births. DES continued to be prescribed until 1971 when the Food and Drug Administration (FDA) issued a Drug Bulletin advising physicians to stop prescribing DES to pregnant women. The FDA warning was based on a study published in 1971 that identified DES as a cause...
