Key result
Over ~61% of Romanian adults have elevated LDL-C exceeding 100 mg/dL.
Why the study?
Dyslipidemia prevalence in unselected populations is often poorly characterized, and laboratory-based datasets can provide real-world insight beyond registry or clinically selected cohorts.
Cross-Sectional (n=219,888)

There is a remarkably high real-world prevalence of atherogenic dyslipidemia, particularly elevated LDL-C, among unselected and healthy Romanian adults, highlighting a substantial unmet need for primary prevention.
High dyslipidemia prevalence in Romanian adults signals substantial CV risk burden; supports established demographic trends yet leaves open need for outcome-linked interventions.
Dyslipidemia is a major cardiovascular risk factor, yet its prevalence in unselected populations is often poorly characterized. Laboratory-based datasets can provide real-world insight beyond registry or clinically selected cohorts. This two-part analysis included a retrospective analysis of 219,888 Romanian adults with routine lipid measurements from multiple laboratory sites across the country. The independent cross-sectional validation cohort comprised 271 clinically healthy adults. Lipid parameters assessed included total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG). High prevalence of lipid abnormalities exceeding guideline-recommended thresholds was observed. In the retrospective cohort, 41.94% had TC > 200 mg/dL, 61.08% had LDL-C > 100 mg/dL, 39.45% had decreased HDL-C, and 30.20% had TG > 150 mg/dL. Age- and sex-specific trends were consistent with known patterns: earlier atherogenic dyslipidemia in males and progressive increase in females with age. The validation cohort showed higher prevalence for elevated TC (47.23%) and LDL-C (84.13%), but lower prevalence for decreased HDL-C (13.65%) and elevated TG (22.87%). In the validation cohort, overall dyslipidemia prevalence was similar between sexes, except for elevated TG, which was approximately three times more prevalent in males. Additionally, in the validation cohort, only 10.7% of participants were free of dyslipidemia, while 62.3% had one trait, 21.7% had two traits, and 5.1% exhibited all three dyslipidemic traits. Dyslipidemia is highly prevalent among Romanian adults, with clear age- and sex-specific patterns. Differences between retrospective and independent cross-sectional data underscore the challenges of estimating population prevalence. Large laboratory databases provide a robust approach for real-world assessment of dyslipidemia burden.

Zaharia et al. (2026) conducted a cross-sectional in Dyslipidemia (n=219,888). Routine laboratory-based lipid assessment was evaluated on Prevalence of elevated LDL-C (> 100 mg/dL). Laboratory-based assessment of Romanian adults revealed a high prevalence of dyslipidemia, with 61.08% exhibiting LDL-C > 100 mg/dL and 41.94% having total cholesterol > 200 mg/dL.
