Prevalence and predictors of implanon utilization among women of reproductive age group in Tigray Region, Northern Ethiopia

BACKGROUND The Ethiopian Federal Ministry of Health introduced provision of the contraceptive Implanon at community level by trained health extension workers in 2009. However, little is known regarding the utilization and factors associated with Implanon use among rural women since the introduction of the community based intervention. Thus, this study assessed the utilization of Implanon and associated factors among reproductive aged women in rural areas of Saesie-Tsaeda Emba and Ofla districts in Tigray, Northern Ethiopia. METHODS A cross sectional community based survey was conducted in May and June 2014. A multistage sampling technique was used to randomly select 524 reproductive aged women (15-49 years). Data was collected through interview using a pre-tested and structured questionnaire. Univariate analysis was done to determine the prevalence for Implanon use, to assess general characteristics of respondents, and to produce summaries. Bivariate analysis was conducted to examine the relationship between each independent variable with the dependent variable. Multivariate logistic regression was conducted to identify factors influencing Implanon use by controlling effect of confounding variables. RESULTS Of all the women, 444 (84.7%) had heard of Implanon. Health extension workers were the primary source of information on Implanon as mentioned by 376 (71.8%) of the respondents. Little more than seven women in every ten, 319 (71.8%), had good knowledge of Implanon and 248 (55.5%) of the women had supportive attitudes towards Implanon use. Among our sample, 10.1% women were using Implanon, 33 (62.3%) reported having received their Implanon at a health post from health extension worker. Women's employment (AOR: 2.73, 95% CI: 1.20-6.21), the number of modern contraceptive methods known (AOR: 2.24, 95% CI: 1.09-4.62), and the number of contraceptive methods ever used (AOR: 11.0, 95% CI: 5.06-23.90) were positively associated with Implanon use. CONCLUSION Trained health extension workers played a major role in information and service provision of Implanon. However, this study revealed that a significant number of women had incorrect information regarding Implanon. Hence, health extension workers and other health professionals should provide appropriate counseling and education regarding Implanon and other contraceptives.
