MATERNAL HEIGHT AND AGE - RISK-FACTORS FOR CEPHALOPELVIC DISPROPORTION IN ZIMBABWE

Maternal age and stature are among several factors used to screen pregnant women for potential risk of labour complications. In a population-based case-control study in Harare, Zimbabwe, multivariate analysis was carried out to evaluate the importance of maternal age and height as risk factors for cephalopelvic disproportion (CPD). Using data abstracted from the medical records of 203 women with operative deliveries due to CPD and 299 women with normal unassisted vaginal deliveries, multiple logistic regression models were developed. Although maternal age <18 years was not a significant risk factor in this study (perhaps because there were few women in this age group), advanced maternal age ( greater-than-or-equal-to 35 years) was associated with a relative risk of 2.7 compared to women 20-34, after adjusting for other demographic and obstetric factors. Maternal height <160 cm was associated with a twofold increased risk of CPD as compared to taller women.
