BACKGROUND // Limited Health Literacy implies an insufficient understanding of relevant health information, being associated with various variables. The objective of the study was to measure the prevalence of the level of Limited Sexual and Reproductive Health Literacy (AS-SR), its associated variables and the differences in scores between levels of AS-SR, universities and science of study in Chilean university students. METHODS //A A multicenter and cross-sectional study, which applied a validated scale to measure levels of AS-SR, was carried out in a sample of 2,186 Chilean university students, categorizing it as high, medium high, medium low and low. The level of Limited AS-SR was obtained by adding the medium-low and low categories. Tests were carried out: descriptive, psychometric and reliability; association, logistic regression and differences between variables of interest. RESULTS //The The prevalence of Limited AS-SR was 52.7%. The variables most associated with the level of Limited AS-SR were: low interest in information about health care (OR=2.819; 95% CI: 2.132-3.726), prevention (OR=2.564; 95% CI: 1.941-3.388), sexuality (OR=2.497; 95% CI: 1.8073.452) and health promotion (OR=1.515; 95% CI: 1.239-1.853); certain sources of Information (OR=1.915; 95% CI:1.614-2.272); low economic income (OR=1.661; 95% CI: 1.361-2.026), among others. There were statistically significant differences in scores between categories of AS-SR levels, universities and study science. The scale had a reliability of 0.940. CONCLUSIONS // More than half of the students have Limited AS-SR, mainly associated with low interest in health information. The scale presents excellent psychometric indicators, being recommended for diagnoses of health situations.
