Research Question: Which are the values of lipids and lipoproteins values of school children high altitude residents in peripheral areas of La Paz city, Bolivia, 2011? Objective: To determine lipids and lipoproteins values of schoolchildren high altitude residents in peripheral areas of La Paz city, Bolivia, 2011 Methods: A descriptive, transversal study was conducted in urban and periurban areas of La Paz city at 3700 meters above sea level. The study included 84 schoolchildren between 6 to 13 years old. A pediatric clinic examination and anthropometric measurements such as weight, height, skin folds and circumferences were performed. Cholesterol, triglycerides, high and low density lipoproteins (HDL-c and LDL-c) were determinate by conventional methods. Results: We found obesity in 8% of school children defined by BMI-age Z score > 2 SD, waist circumference was increased in 24 subjects (28%), with male predomination. Total cholesterol, HDL-c and LDL-c were higher in males than females, difference statistic significant (p=0.05). According to references values at sea level populations, the triglycerides were higher in 13 subjects younger than 10 years (31%), HDL-c was low in 28 subjects (33%). By socioeconomic level we found in the low group high values of triglycerides in 11 subjects younger than 10 years and HDL-c low in 23 subjects (38%), in the medium group we found HDL-c low in 5 subjects (21%). By sex in females we found triglycerides high in 6 subjects younger than 10 years and HDL-c low in 19 subjects (40%), in males younger than 10 years we found triglycerides high in 7 subjects (41%) and HDL-c low in 9 subjects (24%). Conclusions. School children living at high altitude present high values of triglycerides, in subjects under 10 years old with a low socioeconomic level and HDLc were low in this same groups. The primary prevention of risk factors against cardiovascular diseases must to be a priority in health scholar strategies in our context
