Background: Effects of living in urban versus rural locations, or in high- versus low-altitude settings over lipid profiles and the incidence of dyslipidemia remain unclear. Aim: To evaluate the association between urbanization and altitude with five different incident dyslipidemia traits among Peruvian adults aged ≥35 years. Methods: Observational, prospective cohort analysis of the CRONICAS Study. Using baseline (2010) and follow-up data (~2.4 years later), the incidence of each trait was separately analyzed by excluding prevalent cases from the baseline sample. Traits were defined using NCEP ATP-III criteria: hypercholesterolemia (≥200 mg/dL), high low-density lipoprotein cholesterol [LDL-c] (≥130 mg/dL), low high-density lipoprotein cholesterol [HDL-c] (males <40 mg/dL, females <50 mg/dL), high non-HDL-c (≥160 mg/dL), and hypertriglyceridemia (≥150 mg/dL). Urbanization (highly-urban, urban, semi-urban, and rural) and altitude (low- and high-altitude) were the exposures. Incidence rate ratios (IRR) and 95% confidence intervals (95% CI) are reported. Results: The incidence of hypertriglyceridemia, hypercholesterolemia, high LDL-c, high non-HDL-c, and low HDL-c was of 22.0 (95% CI 19.6-24.5), 20.1 (95% CI 17.7-22.5), 15.3 (95% CI 13.2-17.3), 13.0 (95% CI 11.9-15.9) and 11.1 (95% CI 9.6-14.2) cases per 100 person-years, respectively. Compared to lowlanders, the incidence of low HDL-c among highlanders was over three folds higher (IRR 3.22; 95% CI 2.00-5.20) and that of high LDL-c was lower (IRR 0.65; 95% CI 0.45 – 0.94). Urbanization was not significantly associated with dyslipidemia.Conclusions: Individuals living at high-altitude showed better LDL-c, but worse HDL-c profile expressed as lower incidence of high LDL-c and higher incidence of low HDL-c, respectively. Urbanization was not associated with the short-term incidence of dyslipidemia.
