Abstract
Objective: To examine the risk factors and pregnancy outcomes in women aged 40 years
and older at the Korle-Bu
Teaching Hospital, Accra, Ghana.
Methods: A descriptive case–control study comparing women aged 40 years and older
at the time of delivery with those between 20 and 34 who delivered at the Korle-Bu
Teaching Hospital between April 1, 2014 and March 31, 2015. Data were collected
using interviewer-administered
questionnaires and supplemented with information
from patients’ medical records. A multivariate logistic regression was used to estimate
the odds ratio and the 95% confidence interval of various risk factors and complications
associated with delivery in women aged 40 years or older. Statistical significance was
set at P<0.05.
Results: There were 339 women in the study of which 113 were aged 40 years or
older and 226 were aged between 20 and 34 years. Delivery at age 40 years or older
was associated with grand multiparity, and unplanned and undesirable pregnancy.
There was a higher incidence of gestational diabetes (7.1% vs 2.2%, P=0.036), cesarean
delivery (70.1% vs 57.1%, P=0.018), and venous thromboembolism (VTE) (7.1% vs
1.3%, P=0.008) among women older than 40 years. VTE risk was increased sixfold in the
women older than 40 years compared with the younger ones.
Conclusion: Women delivering after age 40 years had a higher incidence of gestational
diabetes, cesarean delivery, and VTE compared with younger women. VTE risk
increased sixfold in the older women.
