Abstract

Background

Half of all cases of blindness are due to cataract. It has been debated whether diets high in polyphenols and antioxidants reduce the risk of cataract. In the present case-control study, we aimed to evaluate the possible association between cataract risk and diet, using calculations of the Dietary Phytochemical Index (DPI) and Mediterranean-style Dietary Pattern Score (MSDPS).

Methods

157 patients with senile cataract were compared to 323 controls who had undergone eye examination during the past year and were not diagnosed with cataract. A validated food frequency questionnaire measured the participant’s habitual diet. The risk of cataract for MSDPS and DPI was assessed by crude and adjusted odds ratios based on multivariate logistic regression analysis, accounting for age and sex.

Results

Analysis was performed on 157 cases and 323 controls. Age, weight, and energy intake significantly differed between the two groups. MSDPS (p = 0.003) and DPI (p = 0.04) were higher in the patients with cataract. A significant association was found regarding DPI in the crude model, indicating that participants of the third quartile of DPI are at 2.34 times higher risk of cataract than the participants in the first quartile (OR: 2.34, 95% CI= 1.34; 4.09).

Conclusions

MSDPS was not significantly associated with cataract risk in crude and adjusted models, although an ascending trend could be observed (p-trend of the crude model= 0.05). A positive association between DPI and cataract risk was found, while this association was not significant for MSDPS. Further studies among newly diagnosed patients with cataract are required.

膳食植物化学指数和地中海式饮食模式评分与白内障风险的关系
背景所有失明病例中有一半是由于白内障引起的。人们一直在争论富含多酚和抗氧化剂的饮食是否能降低白内障的风险。在本病例对照研究中,我们旨在通过计算膳食植物化学指数(DPI)和地中海式饮食模式评分(MSDPS)来评估白内障风险与饮食之间的可能联系。一份经过验证的食物频率问卷测量了参与者的习惯性饮食。基于多变量逻辑回归分析,考虑年龄和性别,通过粗略和调整的比值比评估MSDPS和DPI的白内障风险。结果对157例患者和323例对照组进行分析。年龄、体重和能量摄入在两组之间存在显著差异。白内障患者的MSDPS(p=0.003)和DPI(p=0.04)较高。在粗略模型中发现了与DPI的显著相关性,表明DPI第三个四分位数的参与者患白内障的风险是第一个四分位参与者的2.34倍(OR:2.34,95%CI=1.34;4.09),尽管可以观察到上升趋势(粗略模型的p趋势=0.05)。DPI与白内障风险之间存在正相关,而MSDPS的这种相关性并不显著。需要对新诊断的白内障患者进行进一步的研究。
