We evaluated the benefits and relationship of the number of steps per day to the cardiometabolic risk factors: adiposity indicators; insulin resistance; and metabolic syndrome (MetS) in apparently healthy Brazilian middle-aged men.
Cross-sectional.
Apparently healthy men (age: 50 ± 5 years; n=299) were studied. The number of steps per day was measured by pedometer. The adiposity indicators (waist circumference, total body fat, android and gynoid body fat), serum insulin, glucose and triglycerides, triglycerides/high-density lipoprotein cholesterol (HDL-c) ratio, homeostasis model assessment of insulin resistance (HOMA-IR) and MetS were assessed. Subjects were placed in groups to reflect different levels of steps per day (average of 7 consecutive days): Group 1<10,000 and Group 2 ≥ 10,000. Relationships among variables were measured by multiple linear regressions and the Spearman correlation coefficient as appropriate (p<0.05).
The cardiometabolic risk factors were lower (p<0.05) in Group 2 than in Group 1. The number of steps per day was a negative predictive factor for total body fat, android and gynoid body fat and HOMA-IR independent of age, working position, android fat, overweight/obesity prevalence, and triglycerides/HDL-c ratio. Moreover, there was a negative correlation between the number of steps and total body fat, android and gynoid body fat, HOMA-IR and MetS.
Brazilian middle-aged men performing more than 10,000 steps per day have better cardiometabolic conditions than those walking fewer than 10,000 steps. The number of steps per day is inversely related to the indicators of total and regional adiposity, insulin resistance and MetS.
我们评估了巴西看似健康的中年男性每天步数与心脏代谢危险因素之间的益处及关系，这些危险因素包括肥胖指标、胰岛素抵抗和代谢综合征（MetS）。
横断面研究。
对看似健康的男性（年龄：50±5岁；n=299）进行研究。通过计步器测量每天的步数。评估肥胖指标（腰围、全身脂肪、男性型和女性型体脂）、血清胰岛素、葡萄糖和甘油三酯、甘油三酯/高密度脂蛋白胆固醇（HDL-c）比值、胰岛素抵抗的稳态模型评估（HOMA-IR）和MetS。根据连续7天的平均步数将受试者分为不同组：第1组<10000步，第2组≥10000步。通过多元线性回归和Spearman相关系数（p<0.05）测量变量之间的关系。
第2组的心脏代谢危险因素低于第1组（p<0.05）。每天的步数是全身脂肪、男性型和女性型体脂以及HOMA-IR的负预测因子，独立于年龄、工作岗位、男性型脂肪、超重/肥胖患病率和甘油三酯/HDL-c比值。此外，步数与全身脂肪、男性型和女性型体脂、HOMA-IR和MetS之间存在负相关。
每天步数超过10000步的巴西中年男性比步数少于10000步的男性具有更好的心脏代谢状况。每天的步数与全身和局部肥胖指标、胰岛素抵抗和MetS呈负相关。
