RESUMO
Background: In spite of there are a wide knowledge of the prevalence of hypertension in adult, there is poor information on schoolchildren of different ethnicity and gender.Aim: To compare the levels of blood pressure and other cardiometabolic risk factors for hypertension between schoolchildren of different gender and ethnicity.Material and methods: In a cross-sectional study, 540 schoolchildren (6-13 years) ascendants from a Chilean public school population were analysed by ethnicity and gender in four groups (Mapuches N = 55; European boys N = 199, and Mapuches N = 64, and European girls N = 222). The study included the measurement of cardiovascular (systolic and diastolic blood pressure) as main outcomes, as well as other cardiovascular (resting heart rate), body composition (body mass, BMI, waist circumference, fat mass, muscle mass), muscle strength (handgrip strength of dominant, non-dominant, and mean handgrip strength) as additional cardiometabolic outcomes.Results: The systolic blood pressure was significantly higher in Mapuches girls 126 ± 4 vs. their European counterparts 119 ± 3 mmHg, P < .002, as well as diastolic blood pressure, was higher in Mapuches girls 82 ± 5 vs. European girls 74 ± 3 mmHg, P < .0001. There were more 'prehypertensive' Mapuches girls 10 (15.6%) vs. European peers 22 (9.9%) at P < .0001, and the 'hypertension' was significantly more prevalent in Mapuches boys 19 (34.5%) vs. European peers 39 (19.4%) at P < .0001, as well as in Mapuches girls 16 (25%) vs. European peers 33 (14.9%) at P < .0001. The 'obesity' was less prevalent in Mapuches 10 (18.2%) vs. European boys 55 (27.4%) at P < .0001. The waist circumference was high in European 74 ± 4 vs. Mapuches 67 ± 6â cm, P < .012 in boys, although, waist circumference was high in Mapuches girls 75 ± 5 vs. European peers 71 ± 3â cm, P < .021. There were higher levels of muscle mass in Mapuches boys 19.5 ± 12 vs. European peers 17.1 ± 4â kg, P < .0001.Conclusion: Mapuches girls show higher levels of systolic and diastolic BP than European girls, Mapuches boys and girls are more hypertensive than European peers, but are less obese than European schoolchildren peers. These cardiometabolic differences that are more detrimental for endemic ethnic Latinoamerican groups are in need to be explored further.

BACKGROUND: High-intensity interval training (HIIT) improves cardiometabolic markers, but its effects on the quality of life of patients with type 2 diabetes (T2D) is not well known. AIM: To determine the effects of a 12-week HIIT exercise program on cardiometabolic and quality of life variables of T2D patients. MATERIAL AND METHODS: Nine T2D women were assigned to a HIIT + nutritional education (GE) and 10, to a nutritional education alone group (GC). At baseline and after each intervention, anthropometric and body composition parameters using bio-impedance were assessed, and a blood sample was obtained to measure serum lipid levels, blood glucose and glycated hemoglobin. Quality of life was assessed using the SF-12 questionnaire adapted for the Chilean population. RESULTS: There were no significant changes on the lipid profile variables in the GE group, although HDL cholesterol was increased significantly (p < 0.05) in the GC group. Total fat mass was decreased in the GE group from 43.5 ± 1.5 to 41.9 ± 1.5%, p < 0.01. Fasting glucose and glycated hemoglobin decreased in the GE group. There was a significant correlation between the decrease in total fat mass and that of glycated hemoglobin. There were significant increases in quality of life parameters; physical function, physical role, pain, general health, vitality, emotional role, mental health, and social function in the GE but not in the GC group. CONCLUSIONS: A 12-week program of HIIT plus nutritional education improves cardiometabolic and quality of life parameters on type 2 diabetics.
