Using the Sisterhood Method to Determine the Maternal Mortality Ratios in Six Local Governments of Ondo State, Nigeria

Maternal mortality is a major global health challenge and very common in sub‑Saharan Africa and usually occurs due to complications during pregnancy and childbirth. This study aimed to determine the maternal mortality ratio (MMR) in six local government areas (LGAs) of Ondo State using the sisterhood method.

The study was a cross‑sectional descriptive survey of women in the reproductive age group 15–49 years. Data related to maternal mortality were collected in March 2017 using the indirect sisterhood method. A structured questionnaire was used to collect data and was analyzed using IBM‑SPSS version 25.0 software.

The average MMR in the 6 LGAs was 950 per 100,000 live births with a range of 584–1183 per 100,000 live births. Akoko South had the least MMR of 584 per 100,000 live births, Ondo West had 782 per 100,000 live births, Irele had 982 per 100,000 live births, Owo had 782 per 100,000 live births, Akure South had 1386 per 100,000 live births, and Ile‑Oluji had the highest MMR of 1183 per 100,000 live births. The lifetime risk of dying a maternal death ranged from 0.03 to 0.07, with Ile‑Oluji South having the highest risk. The greatest risk of dying a maternal death was found among adolescents and young adults aged 15–39 years with a peak at 20–24 years.

This study found high MMR in Ondo State, with adolescents and young adults aged 15–39 years being at the highest risk. This calls for consistent interventions to minimize maternal deaths in the state and in Nigeria.
