目的：我们评估了在全国范围内更广泛的美国成年人中，无节制的、生活方式的体力活动(与有组织的体力活动)与视网膜病变患病率之间的具体差异关联。方法：使用2005-2006年国家健康和营养检查调查(NHANES)的数据，确定了1501名年龄在40岁到85岁之间的成年人。使用客观加速度计监测来评估前庭活动和非前庭活动。10分钟的比赛被定义为在中等到剧烈的体力活动(MVPA)临界点上连续10分钟以上，并允许1-2分钟的中断间隔。非比赛MVPA由一场比赛中未累积的MVPA分钟数决定。参与者使用早期治疗糖尿病视网膜病变研究分级标准进行非增殖性视网膜病变筛查，并使用佳能非散瞳视网膜照相机CR6-45 nm进行客观的视网膜成像评估。如果他们被诊断患有冠状动脉疾病、充血性心力衰竭、心脏病发作或中风，则被排除在外。结果：视网膜病变严重的参与者从事较少的有节段性和非节段性的体力活动，有较高的BMI，更有可能患有糖尿病和高血压。与无视网膜病变相比，非斑块性MVPA每增加1分钟/天，参与者中到重度视网膜病变的风险降低7%(OR=0.93；95%CI：0.87-0.99；P=0.04)；在未调整的模型中，结果相似(OR=0.93；95%CI：0.89-0.97；P=0.007)。在多变量模型中，Bouted MVPA与视网膜病变的患病率没有关联。结论：在这个具有全国代表性的成年人样本中，从事非限制性体力活动的人被诊断为中到重度视网膜病变的几率降低。(C)2017年欧洲内科医学联合会。爱思唯尔出版，版权所有。
Objective: We evaluated the specific differential association between non-bouted, lifestyle physical activities (vs. structured exercise; i.e., bouted physical activity) on retinopathy prevalence among a national sample of the broader U.S. adult population.Methods: Data from the 2005-2006 National Health and Nutrition Examination Survey (NHANES) was used to identify 1501 adults, between 40 and 85 years. Bouted and non-bouted physical activities were assessed using objective accelerometer monitoring. A 10-minute bout was defined as 10+ consecutive minutes above the moderate-to-vigorous physical activity (MVPA) cut-point, with the allowance of 1-2-minute interruption intervals. Non-bout MVPA was determined by the number of MVPA minutes not accrued in a bout. Participants were screened for non-proliferative retinopathy using Early Treatment Diabetic Retinopathy Study grading criteria, as well as objective retinal imaging assessments using the Canon Non-Mydriatic Retinal Camera CR6-45NM. Individuals were excluded if they had been diagnosed with coronary artery disease, congestive heart failure, heart attack or stroke.Results: Participants with worse retinopathy engaged in less bouted and non-bouted physical activity, had a higher BMI and were more likely to have diabetes and hypertension. For every 1min/day increase in non-bouted MVPA, participants had a 7% reduced odds of moderate-to-severe retinopathy compared to no retinopathy (OR = 0.93; 95% CI: 0.87-0.99; P = 0.04); results were similar in an unadjusted model (OR = 0.93; 95% CI: 0.89-0.97; P = 0.007). Bouted MVPA was not associated with retinopathy prevalence in the multivariate model.Conclusion: In this nationally representative sample of adults, those who engaged in non-bouted physical activity had reduced odds of a diagnosis of moderate-to-severe retinopathy.
