RESUMEN
<p><b>OBJECTIVE</b>To understand the current status and relative factors of reproductive health (RH) on unmarried floating population.</p><p><b>METHODS</b>Both quantitative and qualitative surveys were employed. Quantitative survey would include questionnaire admimistration, physic examination and laboratory test while qualitative study including focus/nominal group discussion, individual and resource persons interview. All of the investigative targets were selected under informed consent.</p><p><b>RESULTS</b>Among 1333 investigated unmarried floating population, the mean score on knowledge of RH was 12.97 +/- 12.20 (the full score was 100). Among studied persons, 10.20% of them were in favor of unmarried sexual activity while 50.64% of them did not care about it and 26.90% of them had ever experienced sexual activity. Among females who experienced sexual activity, 25.45% of them had induced abortion. It was found, through multivariate logistic analysis, that sexual activity at younger age, less education, agreed on having sexual activity under partner's request, sexual activity in half of a year, and pregnancy were the major risk factors on RH of unmarried floating population.</p><p><b>CONCLUSION</b>The problem on the current status of RH among unmarried floating population needs to be addressed as they were lack of knowledge on RH and having more risk factors on RH.</p>
