In spite of wide international evidence about cardiorespiratory fitness (CRF) and adiposity in association with cardiovascular disease, there is poor evidence about this relationship in schoolchildren of ethnic minorities. To examine the relationship between CRF and body composition on blood pressure (BP) in a sample of ethnic minority schoolchildren from three Latin-American countries. A descriptive cross sectional study of total = 3866, mean age 12.5 (2.7) y [girls = 1997, mean age 12.8 (2.8) y; boys = 1869, mean age 12.2 (2.7) y] schoolchildren from three Latin-American countries (Colombia, Brazil, Chile). Main outcomes were CRF, body mass index (BMI), waist circumference, body fat percentage (%BF), and BP (systolic SB, diastolic BP, and mean arterial pressure (MAP). In both sex, and after adjusting for covariates (age and ethnicity group), negative CRF by Opeak levels were associated with a higher body fatness parameters (BMI, WC, WHtR and %BF <0.001), and blood pressure measures (systolic BP, diastolic BP, and MAP; <0.001). A lower CRF (by Opeak) was associated with a higher BP in girls (systolic SB -0.15; -5.10 (0.30), diastolic BP -0.14; -4.43 (0.23), and MAP -0.15; -4.93 (0.26) at <0.001), and boys (systolic SB -0.02; -0.85 (0.32), DB -0.07; -2.23 (0.23), and MAP-0.06; -1.89 (0.25 at <0.001). There was a significant association between a 'high-CRF + low-%BF' with a lower systolic SB = - 9.6 [0.7], diastolic BP = - 11.0 [0.6]; and MAP level = - 10.6 [0.6] all <0.001). There was a significant association between a 'high-CRF + low-BMI' with a lower systolic = - 10.3 [1.1], diastolic = - 11.2 [1.1], and MAP = - 10.9 [1.0] all <0.001. A lower CRF is associated with a higher body fatness parameters, and higher BP levels in Latin-American ethnic schoolchildren. %BF: Percentage of Body fat; BIA: Bioelectric impedance analysis; BMI: Body mass index; BP: Blood pressure; CRF: Cardiorespiratory fitness; CVD: Cardiovascular disease; LDL-cholesterol: SD: Standard deviation; WC: Waist circumference; WHtR: Waist-height to ratio; Omax: Maximal oxygen consumption; Opeak: Peak of oxygen consumption.
尽管有广泛的国际证据表明心肺适能 (CRF) 和肥胖与心血管疾病有关，但在少数民族的学童中，关于这种关系的证据很少。为了研究在来自三个拉丁美洲国家的少数民族学童样本中，CRF 与身体成分对血压 (BP) 的关系。这是一项对来自三个拉丁美洲国家（哥伦比亚、巴西、智利）的 3866 名，平均年龄 12.5（2.7）岁[女生 1997 名，平均年龄 12.8（2.8）岁；男生 1869 名，平均年龄 12.2（2.7）岁]的总体描述性横断面研究。主要结果是 CRF、体重指数 (BMI)、腰围、体脂百分比 (%BF) 和 BP（收缩压 SB、舒张压 BP 和平均动脉压 MAP）。在两性中，并且在调整了协变量（年龄和种族群体）后，Opeak 水平的负 CRF 与更高的体脂参数（BMI、WC、WHtR 和 %BF <0.001）和血压测量值（收缩压 SB、舒张压 BP 和 MAP；<0.001）相关。较低的 CRF（由 Opeak 表示）与女孩的血压升高相关（收缩压 SB -0.15；-5.10 [0.30]，舒张压 BP -0.14；-4.43 [0.23]，MAP -0.15；-4.93 [0.26]，均<0.001），和男孩（收缩压 SB -0.02；-0.85 [0.32]，DB -0.07；-2.23 [0.23]，和 MAP-0.06；-1.89 [0.25]，均<0.001）。“高 CRF+低-%BF”与较低的收缩压 SB 之间存在显著相关性 = - 9.6 [0.7]，舒张压 BP = - 11.0 [0.6]；和 MAP 水平 = - 10.6 [0.6]，均<0.001）。“高 CRF+低-BMI”与较低的收缩压相关 = - 10.3 [1.1]，舒张压 = - 11.2 [1.1]，和 MAP = - 10.9 [1.0]，均<0.001。较低的 CRF 与较高的体脂参数和拉丁美洲族裔学童的较高血压水平相关。%BF：体脂肪百分比；BIA：生物电阻抗分析；BMI：体重指数；BP：血压；CRF：心肺适能；CVD：心血管疾病；LDL-cholesterol：SD：标准差；WC：腰围；WHtR：腰高比；Omax：最大耗氧量；Opeak：峰值耗氧量。
