Data collected included the sociodemographic characteristics of the respondents age, marital status, tribe, level of education, occupation, parity , opinions and preferences regarding LMP and ultrasound scan dates, and their attitudes toward postdatism and induction of labor in relation to estimated dates.
The primary outcome measure was willingness to accept induction of labor at an LMP-derived gestational age of 40 weeks plus 10 days when late pregnancy ultrasound scan-derived gestational age was less than 40 weeks plus 10 days. The first trimester was defined as a gestational age of 1—13 weeks, the second trimester as 14—27 weeks, and the third trimester as 28—42 weeks. Further, the early second trimester was defined as a gestational age of 15—22 weeks and the late second trimester as 23—27 weeks.

Predicting delivery date by ultrasound and last menstrual period in early gestation.

This poor knowledge invariably translated into the observed perception of respondents toward induction of labor for postdatism, as more than half of the women This attitude poses a great challenge to perinatal care in our environment because an ultrasound scan is usually carried out in the third trimester when the margin of error is up to 3 weeks.

The recent proliferation of ultrasound scan services in our environment came with a wave of optimism that ultrasound scanning could accurately determine all aspects of fetal well-being, hence only the well-educated or informed could question or resist its results. This misconception is further worsened by uncontrolled purchasing and use of ultrasound scanning machines by poorly trained personnel who advertise themselves as sonologists or sonographers.
What is even more worrisome is the increasing number of self-referrals for ultrasound by our pregnant women merely to know the EDD which they usually hold on to.
Legislation to regulate the acquisition and use of ultrasound by health professionals in the country may help to keep this problem in check. Such legislation should also discourage self-referral by pregnant women for ultrasound. This will further help to prevent our women from visiting poorly trained sonologists and guard against the possible effects of unreliable ultrasound scan results on maternal and neonatal health.
Tertiary education was identified in this report as a strong determinant of acceptance of induction of labor for postdatism using the last menstrual date.
Why would I have a dating scan?
This may be explained by the expected impact of education on uptake of maternal and neonatal health services, as observed by previous authors. Also, the lesser educated are more likely to rely more on the impression created outside about a procedure like ultrasound, whether right or wrong. As pointed out by Olusanya et al, 12 the higher the educational status of the woman, the higher the social class, and this no doubt may explain the higher acceptance rate among women of higher social class than among women of lower social class.
