Background: Transitioning HIV care toward a client-centered model is a key strategy for improving treatment outcomes and controlling the spread of HIV infection. Evaluating service accessibility, quality, and client satisfaction is essential for improving strategic planning and strengthening health service delivery. Aim: To assess the accessibility and quality of client-centered health services among people living with HIV. Materials and methods: A facility-based cross-sectional study was conducted. Data were collected using structured questionnaires from 50 clients and 30 health managers who participated voluntarily. The reliability of the questionnaire, measured using Cronbach’s alpha, ranged from 0.673 to 0.783. Data were analyzed using SPSS version 23.0 with both descriptive and analytical statistical methods. Quantitative variables were summarized using means and standard deviations, and statistical significance was determined at p < 0.05. Results: HIV-related services were found to be highly centralized at the NCCD, particularly for blood testing (96.8%) and inpatient care (71.4%). Overall, 84% of clients reported the need to access services outside NCCD, with the highest demand for internal medicine (32%), dental services (14%), and surgical services (14%). Among the barriers to accessing care, 75% were related to stigma and discrimination associated with HIV status, while 18% were linked to healthcare workers’ attitudes. In addition, 56.7% of healthcare facilities had not conducted HIV-related training, and only 40% had dedicated rooms ensuring confidentiality. Client satisfaction was strongly correlated with healthcare providers’ attitudes and communication (R = 0.614) and confidentiality (R = 0.578), both showing significant associations (p = 0.000). Conclusion HIV services remain highly centralized at NCCD, while the readiness of primary and referral healthcare facilities remains insufficient. Strengthening a client-centered care approach requires improving healthcare workers’ attitudes and communication, ensuring confidentiality, and implementing continuous HIV-related training for healthcare providers.

Background: Obesity, especially central obesity, is a risk factor for non-communicable chronic diseases such as dyslipidemia, type 2 diabetes mellitus (T2DM), cardiovascular diseases (CVD), and metabolic syndrome (MetS). Aim: Study the association between the subcutaneous fat area (SFA) and visceral fat area (VFA) with lipid metabolism parameters in adults with MetS. Materials and Methods: Data from 1511 participants who visited the ‘NURA Mongolia’ Ai Health screening center between September 2023 and February 2024, including general information, DEXA (Dual X-ray Absorptiometry), and biochemical analysis results, were used. Metabolic syndrome (MeS) was assessed based on the harmonizing criteria 2009 (≥3 criteria). VFA and SFA were categorized into four groups using quartiles (Q1-Q4). Statistical analysis was performed using SPSS v26, including T-tests, multiple logistic regression (OR, 95% CI), and ROC (AUC) analysis. Results: The average age of the participants was 30.5±3.9 years, with a BMI of 25.1 kg/m², and 49.5% were male. The group with MetS (n=531) had significantly higher levels of VFA and SFA compared to the group that rated their health as relatively healthy and had no clinical diagnosis (n=979) (control group) (p<0.0001), with males showing higher VFA and females showing higher SFA (p<0.0001). The Q4 group for VFA had a significant association with MetS in males (4.611, 95% CI=2.394–9.591) and females (2.253, 95% CI=1.097-3.912) (p<0.001). Logistic regression analysis showed that increased VFA was more strongly associated with MetS in males (β=0.325, p<0.0001) and females (β=0.338, p<0.003) than BMI. The AUC for predicting MetS was 0.790 (95% CI=0.750-0.831) for VFA and 0.401 (95% CI=0.351-0.451) for SFA, with all results being statistically significant (p<0.001). VFA had a higher predictive value compared to other markers. Conclusion In healthy men with metabolic syndrome, VFA is more prominently defined, while SFA is higher in healthy women. Since VFA is a better predictor of metabolic syndrome than SFA, it increases the risk of diseases such as cardiovascular diseases and type 2 diabetes in men, whereas SFA in women serves as a protective factor.
