Introduction: Many developing countries are characterized by rapid population growth, which is partly attributed to high fertility rates, high birth rates, accompanied by steady declines in death rates, low contraceptive use and high but declining mortality rate. AIM: To determine the factors influencing family planning method use among women of reproductive age in urban communities of Imo state, Nigeria. Methodology: The study was a community based descriptive cross-sectional study involving 560 women of reproductive age who met the inclusion criteria and were selected using the multistage sampling technique. The data were collected using a pretested, semi-structured and interviewer administered questionnaire and were analyzed using EPI-INFO version 3.2.1. A p-value ≤ 0.05 was considered significant. Results: The mean age of the respondents was 32.7 ± 7.7 years with most of the women (99.1%) being aware of family planning. The common methods known were; pills (65.2%), injections (62.5%), condoms (61.3%) and natural family planning methods (49.5%). The prevalence of ever use and current use of family planning was 54.1% and 35.1% respectively and the commonest method ever (36%) and currently (26%) used was the condom. The factors found to significantly influence family planning method use in the study were: age of women, religion, family size, number of male children, monthly income, being able to access and pay for family planning services without partners financial support, contraceptive knowledge, prior discussion of family planning with partner, partner being in support of modern family planning methods use and previous use of any form of contraception. Conclusion: Most of the factors found to influence use can be modified by appropriate intervention programs.? Thus there is need to institute these intervention programs by authorities concerned so as to increase utilization of services and reduce consequent problems.
