BACKGROUND

The role of antenatal care in ensuring improved pregnancy outcome is no longer in doubt. Ensuring early booking for antenatal care can optimize this benefit.

OBJECTIVE

To determine the gestational age at first antenatal attendance in pregnant women at the Lagos University Teaching Hospital (LUTH).

METHODS

A cross-sectional study of all pregnant women that booked at the antenatal clinic in LUTH from November 2005 to June 2006 was undertaken to determine the gestational age at booking.

RESULTS

The mean age of the women was 30.5 +/- 4.5 years (range 18-46 years) and the mean gestational age at first antenatal visit for the study was 19.1 +/- 7.8 weeks (range 6 to 40 weeks). While the nulliparous and primiparous women booked earlier (mean 18.5 +/- 8.3 and 18.4 +/- 7.4 weeks respectively), those with parity 5 booked much later, mean 25.9 +/- 8.6 weeks and this was significant statistically (p < 0.0002). Only 317 (27%) had booked as at 13 weeks, the end of first trimester while the majority 647 (55.2%) booked in the second trimester (14 to 26 weeks gestation). 70 women (6%) had their first antenatal visit at > or = 34 weeks while 22 (1.9%) first booked at > or = 37 weeks gestation. However, 3 women (0.3%) booked at 40 weeks gestation. Majority of the women belonged to social class 3 (496; 42.3%) with majority of their partners also in social class 3 (490; 41.8%). However women in social class 1 and those whose partner belong to social class 1 booked earlier than the other social classes and this also was statistically significant (p < 0.0008).

CONCLUSION

Nulliparous and primiparous women as well as women in social class 1 and those whose partners are in social class 1 tend to book earlier for antenatal care services. Aggressive and extensive health education on the benefit of antenatal care and the need for early booking in the first trimester is advocated. The hospital may need to review the cost of antenatal care and delivery as well as improve on the whole service package.

背景

产前护理在确保改善妊娠结局方面的作用已毋庸置疑。确保尽早预约产前护理可使这一益处最大化。

目的

确定拉各斯大学教学医院（LUTH）孕妇首次产前检查时的孕周。

方法

对2005年11月至2006年6月在LUTH产前诊所预约的所有孕妇进行横断面研究，以确定预约时的孕周。

结果

研究对象的平均年龄为30.5±4.5岁（范围18 - 46岁），首次产前检查时的平均孕周为19.1±7.8周（范围6至40周）。未生育和初产妇预约较早（分别为平均18.5±8.3周和18.4±7.4周），而生育5胎的产妇预约较晚，平均为25.9±8.6周，且具有统计学意义（p < 0.0002）。截至孕13周（孕早期结束）时，只有317人（27%）预约，而大多数647人（55.2%）在孕中期（孕14至26周）预约。70名女性（6%）在孕34周及以上进行首次产前检查，22名（1.9%）在孕37周及以上首次预约。然而，有3名女性（0.3%）在孕40周时预约。大多数女性属于社会阶层3（496人；42.3%），其伴侣大多也属于社会阶层3（490人；41.8%）。然而，社会阶层1的女性及其伴侣属于社会阶层1的女性比其他社会阶层预约更早，且具有统计学意义（p < 0.
