    Objectives: To analyze the causes and indications of C-sections conducted at the tertiary referral center and to forecast future patterns. Methods: We retrospectively analyzed 25,311 delivery records from 2013 to 2022 at the National Center for Maternal and Child Health, Mongolia. All C-sections from 22 weeks’ gestation onward were included. Data were collected using a structured questionnaire form including maternal, obstetric history, surgical indications, and other influencing factors. Causes of C-sections were identified through descriptive statistics, logistic regression, and ARIMA time-series modeling. Statistical analysis was performed using Stata BE 18.0, with p < 0.05 considered significant. Results: The mean gestational age was 38.1±2.09 weeks, the 88.4% of pregnancies were term deliveries, and 42.6% were emergency C-sections. The most common indications for C-section were previous C-section, maternal comorbidity, severe preeclampsia, and fetal distress. According to time-series analysis, despite of no significant change in the C-section rate during the study period, the trends in C-sections are growing. The percentage of nulliparous women in total C-sections is likely to increase by 0.81% per year. In 2030, the percentage of C-sections will reach 35.5%, whereas the percentage of emergency C-sections in total C-sections will reach 59.5%. Conclusions: C-sections for nulliparous women were mainly due to failed birth induction, failed labor stimulation, and fetal distress. It is estimated that the percentage of C-sections in total births will increase by 0.02% annually, reaching 35.5% by 2030.

    Background: The triglyceride-glucose (TyG) index has emerged as a reliable surrogate marker of insulin resistance. This study aimed to investigate the association between blood pressure (BP) levels and the TyG index and to assess whether even modest elevations in BP were associated with higher TyG index values. Methods: A cross-sectional analysis was conducted using data from 120,264 participants who underwent nationwide health screening in Mongolia between 2023 and 2024. BP was categorized into five stages. The TyG index was calculated based on fasting triglyceride and glucose levels. Results: The mean TyG index increased progressively with advancing hypertension stages (p for trend <0.001). Multivariate analysis showed that even elevated BP was independently associated with a higher TyG index (adjusted OR 1.108, 95% CI 1.039-1.183; p = 0.002), with the association strengthening across hypertension stage 1 (adjusted OR 1.238, 95% CI 1.200-1.277), stage 2 (adjusted OR 1.516, 95% CI 1.463-1.572), and hypertensive crisis (adjusted OR 1.575, 95% CI 1.350-1.836) (all p < 0.001). Central obesity further amplified the association between hypertension stage and TyG index levels. Among participants without central obesity, the TyG index increased from 8.086 (95% CI: 8.079-8.093) in the normal BP group to 8.449 (8.362-8.536) in the hypertensive crisis group. Similarly, among those with central obesity, the TyG index rose from 8.345 (8.336-8.354) in the normal group to 8.732 (8.685-8.778) in the hypertensive crisis group. Conclusions: This study demonstrates that the TyG index rises consistently with increasing BP stages, even at early elevations, suggesting that insulin resistance may begin at modest blood pressure increases.
