To study the character and the intensity of lens opacity and the visual acuity in cataract patients and controls and to determine the association of these indices with the subjects' physical activity.
The lens opacity in 110 eyes of patients (n=110) aged 60.3+/-0.4 (mean+/-SEM) years admitted to the Clinic of Eye Diseases of Kaunas University of Medicine Hospital for cataract surgery and the lens opacity of 100 eyes of controls (n=50) aged 59.8+/-0.4 (mean+/-SEM) (p>0.05) years hospitalized in the Clinic of Skin and Venereal Diseases was evaluated according to the Lens Opacity Classification System, version III. Visual acuity was investigated using the Snellen chart. Physical activity in metabolic equivalent minutes per week (MET-minutes/week) was evaluated according to the International Physical Activity Questionnaire.
The means of the intensity of lens opacity of patients with cataract were significantly higher, and the means of visual acuity and physical activity were significantly lower, compared to controls (p<0.01-0.001). For less active patients (<5900 MET-minutes/week) with the right eye examined, the odds ratio of cataract was by 7.00 (95% confidence interval 2.93-16.74, p<0.001) and for those with the left eye studied by 4.43 (95% confidence interval 1.97-9.98, p<0.001) times higher, compared to physically active (>5900 MET-minutes/week) patients. Physical activity was inversely correlated (r=-0.452, p<0.05) with the lens opacity in the cortex in physically active (>5900 MET-minutes/week) subjects with cataract who underwent the examination of the left eye.
The intensity of lens opacity and cataract are statistically significantly related to physical activity.
研究白内障患者及对照组晶状体混浊的特征、程度以及视力，并确定这些指标与受试者体力活动之间的关联。
对考纳斯医科大学医院眼科诊所收治的110例年龄为60.3±0.4（均值±标准误）岁、因白内障手术入院患者的110只眼睛，以及皮肤与性病诊所收治的50例年龄为59.8±0.4（均值±标准误）（p>0.05）岁对照组患者的100只眼睛，依据晶状体混浊分类系统第三版评估晶状体混浊情况。使用斯内伦视力表检查视力。根据国际体力活动问卷评估每周代谢当量分钟数（MET-分钟/周）的体力活动情况。
与对照组相比，白内障患者晶状体混浊程度的均值显著更高，而视力和体力活动的均值显著更低（p<0.01 - 0.001）。对于右眼接受检查的体力活动较少（<5900 MET-分钟/周）的患者，患白内障的优势比为7.00（95%置信区间2.93 - 16.74，p<0.001），对于左眼接受研究的患者，该优势比为4.43（多95%置信区间1.97 - 9.98，p<0.001），高于体力活动较多（>5900 MET-分钟/周）的患者。在接受左眼检查的体力活动较多（>5900 MET-分钟/周）的白内障受试者中，体力活动与皮质晶状体混浊呈负相关（r = -0.452，p<0.05）。
晶状体混浊程度和白内障与体力活动在统计学上显著相关。
