ABSTRACT:
Estimating abortion prevalence is very crucial for public health, especially in the areas of reproductive health. Due to its illegality induced abortion complication has been adopted as one of the means by which abortion prevalence in Nigeria can be estimate. But in this paper, however, we suggested entirely different approach, the capture-recapture experiment. We demonstrated its usage by estimating abortion prevalence in Anambra State, South East Nigeria. Information on abortion were collected from two surveys—hospital out-patients and workplaces/schools/marketplaces. Based on the information collected, capture-recapture method was used to estimate the prevalence in the State. The two surveys identified a total of 390 abortions in the State in 2014. When this number was compared with the ascertainment corrected estimate of 1327 obtained with capture-recapture experiment, it appeared to represent 29% of the true abortion prevalence in the State. To the best of our knowledge this is the first use of such method to estimate abortion prevalence in Nigeria. We therefore advocate its usage in absence of any gold standard.
Key words: Capture-recapture, estimating prevalence, hidden population.
