This analysis aimed at examining the association between the level of knowledge about long-acting/permanent methods of contraceptives (LAPM) and nonuse of LAPM among currently married, nonpregnant, and fecund women aged 15 to 49 years intending to limit childbearing. Data were derived from a cross-sectional study in Tuban, Kediri, and Lumajang District (East Java Province) and Lombok Barat, Lombok Timur, and Sumbawa District (Nusa Tenggara Barat Province) in June 2012. Information was obtained from 4323 respondents. Using multivariate logistic regression, we found that women with moderate levels of LAPM knowledge were less likely to use LAPM than women with high levels of knowledge (adjusted odds ratio [aOR] = 2.01, 95% CI = 1.51-2.68). Women with low level of LAPM knowledge were less likely to use LAPM than women with high levels of knowledge (aOR = 4.25, 95% CI = 3.37-5.36). Efforts to strengthen counseling services and increased provider knowledge and counselling skills are important to improve women’s knowledge about and use of LAPM. © 2017, © 2017 APJPH.
