许多研究已经证明了长时间坐着和看电视对健康的不良影响。这些久坐不动的消遣与肥胖和其他心脏代谢风险因素的风险增加有关。然而，没有研究专门在美国的低收入少数民族社区调查这些协会。方法：这项横断面、以社区为基础的研究在德克萨斯州南达拉斯进行。多变量有序逻辑回归模型被用来检查久坐行为（自我报告）和客观评估的肥胖（BMI，腰围）的措施之间的关联。结果：在低收入的少数民族人群中，坐着时间、电脑使用和交通时间与BMI升高之间存在独立且显著的相关性（P <0.05）。腰围的增加也与坐着的时间、使用电脑和通过时间的增加有关，但没有统计学意义。结论：被动休闲活动时间的增加是该人群肥胖的风险标志。
BACKGROUND Numerous studies have documented adverse health effects from prolonged sitting and TV viewing. These sedentary pastimes are linked to increased risk for obesity and other cardiometabolic risk factors. No studies, however, have examined these associations specifically in low-income, minority communities in the US. METHODS This cross-sectional, community-based study was conducted in South Dallas, TX. Multivariable ordered logistic regression models were used to examine the association between sedentary behaviors (self-report) and measures of objectively assessed obesity (BMI, waist circumference). RESULTS Among a low-income, ethnic-minority population, there were independent and significant associations between higher levels of sitting time, computer use, and transit time with elevated BMI (P < .05). Elevated waist circumference was also linked to increased sitting time, computer use, and transit time, yet without statistical significance. CONCLUSIONS Increased time spent in passive-leisure activities is a risk marker for obesity in this population.
