In 372 girls, internalising problems were measured using the Youth Self Report, and use of OCP was determined by parental interview and self-report questionnaire across two subsequent waves (mean ages 14.9 and 17.9 years, respectively). Multiple regression analyses were performed to determine the association. Analyses were adjusted for various sociodemographic factors and adjusted for previous internalising problems assessed at a mean age of 14.9 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S2056472424008597_as4\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In total, 204 girls (54.8%) used OCP.
