Maternal Short Stature as a Risk Factor to Cesarian Section in Nulliparous Filipino Patients: a Prospective Cohort Study

Nicole Angela A. Domingo

 

Abstract:

Objective: To establish a correlation between the maternal height of Filipino nulliparas and their route of delivery which can be used as a risk indicator for a high probability of cephalopelvic disproportion. Methods: This is a prospective cohort study involving 68 term, nulliparous Filipino women between the ages of 18 to 35 years old without medical and obstetric complications, with spontaneous onset of labor. Short stature was defined as height of 150cm or less. Subjects were selected by convenience sampling. Chi-Square Test was used to establish the correlation between short stature and cesarean section. Results: Fourteen (41.2%) subjects with a height of ?150cm delivered via normal spontaneous vaginal delivery (NSVD) and twenty (58.8%) subjects via cesarean section (CS); whereas twenty-three (67.6%) subjects with a height of >150cm delivered via NSVD versus eleven (32.4%) subjects delivered via CS. The results showed that there was a significant association noted as proven by the p-value of 0.03. The proportion of women delivering via CS among those with ?150cm height was significantly higher than those with a height >150cm. The risk of women ?150cm for delivering via CS was two times higher than those with a height of >150cm (RR=1.82; 95% CI: 1.04 – 3.19, p=0.03). Conclusion: Filipino women with heights of 150cm and less are at risk of obstructed labor due to cephalopelvic disproportion and should be referred early to tertiary hospitals where labor can be closely monitored and cesarean section performed if necessary.
