RESUMO

PURPOSE: The aim of the present study was to report for the first time the prevalence of hypertension and its phenotypes in obese children and in children with central obesity in a large sample of Greek children. METHODS: A regionally representative sample of 2263 schoolchildren (50.3% boys) (9-13 years) having full data on blood pressure assessment, physical examination, anthropometric, and physical activity participated in a cross-sectional study in Greece. RESULTS: Prevalence of stage 1 and 2 hypertension, of isolated systolic hypertension (ISH) and of combined systolic or diastolic hypertension, was significantly higher for obese children and children on the 3rd tertile of waist circumference in the total sample, as well as in each gender separately. ISH was the most prevalent phenotype reaching 24.3% in obese children and 17.5% in children on the highest tertile of waist circumference. Obese children and children on the highest tertile of waist circumference had 6.31 times and 3.94 times, respectively, higher likelihood to have abnormal systolic or diastolic blood pressure (SBP or DBP) than their normal-weight counterparts. CONCLUSIONS: Prevalence of hypertension and especially ISH in obese children and in children with central obesity in Greece are among the highest reported in Europe. Future public health initiatives should aim to prevent or tackle several underlying factors related to childhood hypertension, focusing primarily on children with excess body weight.

RESUMO

BACKGROUND AND AIMS: Association of dairy products and meat consumption with macrocirculation is previously described, but such association with microcirculation is poorly investigated. We aimed to test the hypothesis that the consumption of high- and low-fat dairy products as well as red, white, and processed meat is associated with retinal vessel calibers in adults at an increased risk of cardiovascular disease (CVD). METHODS AND RESULTS: In consecutive subjects (n = 181, age: 51.3 ± 12.4 years, 51.4% women) without CVD and diabetes mellitus but with increased CVD risk, we obtained digital left and right retinal images. These images were assessed with validated software to determine central retinal arteriolar and venular equivalents and the arteriolar to venular ratio (CRAE, CRVE, and AVR, respectively). The consumption of dairy products and meat was assessed through 24-h recalls in all volunteers. After adjustment for potential confounders, the following findings were obtained: (i) low-fat milk and yogurt were positively associated with CRAE (b=0.145, p=0.031 left; b=0.141, p=0.038 right) and inversely associated with CRVE (b=-0.155, p=0.026 left; b=-0.146, p=0.041 right); (ii) low-fat cheese was positively associated with CRAE (b=0.164, p=0.011 left and b=0.155, p=0.017 right); and (iii) red meat was inversely associated with CRAE (b=-0.143, p=0.032 left; b=-0.114, p=0.050 right). High-fat milk, yogurt, and cheese or white and processed meat were not found to be associated with retinal vessel calibers. CONCLUSIONS: High consumption of low-fat milk, yogurt, and cheese and low consumption of red meat could be beneficial for retinal microvascular health. Prospective studies are needed to verify these findings.
