摘要:Background: Understanding patterns of health service utilization can improve health care and increase use of health services. We examined patterns of health service utilization among residents of Ulaanbaatar, Mongolia. Methods: A total of 500 adults were surveyed using paper-based questionnaires. The χ2 test and multiple logistic regression were used to identify associations between factors. Results: 44.1% of respondents had visited a physician during the previous 12 months. After controlling for determinants, the significant predictors of utilization of health service were attention to health examinations (OR = 3.6, CI: 1.93–6.76), being married (OR = 2.7, CI: 1.50–4.72), being satisfied with the overall cleanliness of the hospital (OR = 2.4, CI: 1.12–5.19), being a nonsmoker (OR = 2.2, CI: 1.21–3.98), having periodic physical examinations (OR = 2.2, CI: 1.25–3.71), not being a hospital patient during the previous 3 years (OR = 2.1, CI: 1.22–3.73), having proper documentation (OR = 1.9, CI: 1.10–3.43), having medical insurance (OR = 1.9, CI: 1.96–3.28), not wanting to receive information on food and nutrition (OR = 0.6, CI: 0.36–0.96), having more than 5 household members (OR = 0.5, CI: 0.50–0.85), low income (OR = 0.5, CI: 0.30–0.85), lack of concern for food and nutrition (OR = 0.5, CI: 0.28–0.84), self-medication during the past 12 months (OR = 0.4, CI: 0.24–0.69), and desire for treatment abroad (OR = 0.4, CI: 0.20–0.60). Conclusions: A number of health-related behaviors and sociodemographic factors were important predictors of health service utilization.
