The aim of the present study was to examine the sex-related associations between accelerometer-measured daily step counts and adiposity indicators in adults from eight Latin American countries. We analyzed data from 2524 adults (aged 18-65 years) from the Latin American Study of Nutrition and Health. Device-measured daily step counts were measured by accelerometers (ActiGraph GT3X). The outcomes were body mass index (BMI; (kg/m2), waist and neck circumference (in cm). Overall, the mean of daily steps counts, BMI, waist and neck circumference were 10699.8, 27.3, 89.6, and 35.8. Weak and negative associations were observed between daily steps counts and BMI ( = -0.17; < 0.05) and waist circumference ( = -0.16; < 0.05); however, step counts was not associated with neck circumference. Daily steps counts were negatively associated with BMI (β: -0.054; 95%CI: -0.077; -0.012) and waist circumference (-0.098; -0.165; -0.030) independently of age and socioeconomic level. In men, there were significant negative associations between daily steps counts with BMI (-0.075; -0.119; -0.031) and waist circumference (-0.140; -0.233; -0.048), and in women, there was no significant association with either of the body composition indicators. The findings from this study need to be examined in prospective settings that use device-measured from Latin America.
本研究旨在探讨八个拉丁美洲国家成年人中,加速度计测量的日常步数与肥胖指标之间的性别关联。我们分析了拉丁美洲营养与健康研究中 2524 名成年人的数据。设备测量的日常步数通过加速度计(ActiGraph GT3X)测量。结果是体重指数(BMI;(kg/m2)、腰围和颈围(cm)。总体而言,日常步数、BMI、腰围和颈围的平均值分别为 10699.8、27.3、89.6 和 35.8。日常步数与 BMI( = -0.17; < 0.05)和腰围( = -0.16; < 0.05)之间存在微弱的负相关;然而,步数与颈围无关。日常步数与 BMI(β:-0.054;95%CI:-0.077;-0.012)和腰围(-0.098;-0.165;-0.030)呈负相关,与年龄和社会经济水平无关。在男性中,日常步数与 BMI(-0.075;-0.119;-0.031)和腰围(-0.140;-0.233;-0.048)之间存在显著的负相关,而在女性中,与任何一种身体成分指标均无显著相关性。这些发现需要在使用拉丁美洲设备测量的前瞻性研究中进行检验。
