Background: Human trafficking is a worldwide public health problem that is not easily identified. The state of Colorado has a 33-item checklist used by the Colorado Department of Human Services (CDHS) that reviews risk-factors with individuals at risk for trafficking. Objective: To identify trends in human trafficking in the state of Colorado and the utility of the 33-item checklist. Participants and Setting: Data was requested from CDHS via the Trails Database between Jan 2017-Oct 2018. Checklists were completed by 1,672 subjects. Methods: Data included subject ID, question text, category (sex vs. labor trafficking), order, and answer. Frequency of question answer (i.e. Yes, No, or Unanswered) was presented as count and percentage. Logistic regression was performed to determine the probability of the question answer based on the question and study ID. Linear regression was performed to determine the association of questions answered over time. Results: Of 71,896 questions, 27,240 questions were unanswered (38%). Drug charges, truancy, and family dysfunction were the most commonly identified risk factors. There was no association between the subject number (OR 0.994, 95% CI 0.994 – 0.995) and the question (OR 0.968, 95% CI 0.966 – 0.970) on whether the question was answered or not. There was a 7.4% decrease (95% CI 7.3-7.4%) in answered questions for each additional subject screened. Conclusion: The CDHS checklist identified similar risk factors for human trafficking as prior studies. However, the data had inconsistently answered questions, which may limit utility in identifying at-risk populations. A shorter checklist may be more useful.
