关于身体活动、身体健康和健康的研究由于身体活动的无效、不可靠或不切实际的衡量标准而受到阻碍。这份报告检验了久坐特征(静息心动过速、肥胖和低肺活量)作为身体健康预测因子的有效性，这是通过最大跑步机运动试验进行评估的。研究参与者是女性(n=3943)和男性(n=15627)，至少去过德克萨斯州达拉斯的库珀诊所一次[美国]。通过多元回归分析，检验了久坐特征与身体健康的关系。在所有年龄组和性别组中，久坐特征与身体健康有关，这可以解释跑步机时间变化的12%-40%。当吸烟这一简单的体力活动指数和久坐特征被纳入预测身体健康的模型时，女性的R2值在0.2到0.53之间，男性在0.45到0.61之间，P<；0.0001有显著意义。这些模型在身体健康方面的差异大约是之前报道的两倍。在流行病学研究中，将久坐特征测量添加到简单的体力活动指数中，可以提供对身体健康的有效估计。
Studies on physical activity, physical fitness, and health have been hampered because of invalid, unreliable, or impractical measures of physical activity. This report examines the validity of sedentary traits (resting tachycardia, obesity, and low vital capacity) as predictors of physical fitness as assessed by a maximal treadmill exercise test. Study participants were women (n = 3,943) and men (n = 15,627) with at least one visit to the Cooper Clinic in Dallas, Texas [USA]. Association of the sedentary traits with physical fitness was examined by multiple regression analyses. Sedentary traits were associated with physical fitness in all age and sex groups, accounting for 12-40% of the variance in treadmill time. When smoking, a simple physical activity index, and sedentary traits were included in a model to predict physical fitness, R2 values ranged from 0.20 to 0.53 in women and 0.45 to 0.61 in men and were significant at p < 0.0001. These models account for approximately twice as much variance in physical fitness as has been reported previously. The addition of sedentary traits measurements to a simple physical activity index provides a valid estimate of physical fitness in epidemiologic studies.
