# Caesarean sections among east African refugees and their host population: a 20-year retrospective study in western Tanzania

## TL;DR

This 20-year study in Tanzania examines caesarean section rates among East African refugees and local populations, highlighting common reasons for the procedure.

## Contribution

The study provides a long-term analysis of CS in a refugee setting, comparing trends between refugees and host populations.

## Key findings

- 8,461 caesarean sections were performed over 20 years, with Tanzanians making up 25% of cases.
- Cephalopelvic disproportion, previous scar, and fetal distress were the most common indications for CS.
- Significant differences were found in patient age distribution for several CS indications between refugees and Tanzanians.

## Abstract

Half of the 35.3 million refugees worldwide are women and a third are of childbearing age, making reproductive healthcare in humanitarian settings indispensable. Caesarean section (CS) is the most common operation worldwide, accounting for 18.6% of births.

This study provides a descriptive analysis of caesarean sections (CS) in a protracted refugee setting.

This study is a retrospective review of CS recorded in logbooks between November 2000 and September 2020, inclusive. Data was abstracted from paper logbooks and included date, nationality, sex, age, and indication. Analysis was performed in STATA.

8,461 CS were performed over the 20-year period. The average age was 24.6 years. Tanzanian patients made up 25% (n=2,116) of the population. The most common indications for CS for both Tanzanians and refugees were cephalopelvic disproportion (CPD), previous scar, and fetal distress. There was a significant difference in the proportion of adolescent and adult patients for the indications of CPD, previous scar, fetal distress, malposition, placenta previa, prolapse, and antepartum hemorrhage (APH).

There is a significant amount of CS performed in this humanitarian setting. Refugees and Tanzanians utilize these services. Outcome data are needed to identify if CS in this setting reduces neonatal and maternal morbidity and mortality.
