We investigated the association between socioeconomic status (SES) and the prevalence of blepharoptosis in a representative South Korean population.
This cross-sectional study was based on data obtained in the Korea National Health and Nutrition Examination Survey from 2010 to 2012. In total, 17,178 Korean adults (7,261 men and 9,917 women) aged 19 years or older were enrolled. Blepharoptosis was defined as a marginal reflex distance 1 (MDR 1) lower than 2 mm. Household income and education level were used as indicators of SES. Univariate and multiple logistic regression analyses were conducted to analyze the relationship between SES and the prevalence of blepharoptosis.
Household income was inversely associated with the prevalence of blepharoptosis in women [adjusted odds ratio (aOR) and corresponding 95% confidence interval (95% CI) was 1.894 (1.336, 2.685)], and educational level was inversely associated with blepharoptosis in both men and women [aORs and 95% CIs were 1.572 (1.113, 2.219) and 1.973 (1.153, 3.376), respectively]. After adjusting for household income and educational level, low SES was associated with a high prevalence of blepharoptosis in women only.
Socioeconomic disparities in the prevalence of blepharoptosis were found among women. Indeed, future research using a prospective design to determine the causal relationship between SES and blepharoptosis may identify SES as a risk factor for this condition.
我们在具有代表性的韩国人群中研究了社会经济地位（SES）与上睑下垂患病率之间的关联。
这项横断面研究基于2010年至2012年韩国国家健康与营养检查调查所获得的数据。总共纳入了17178名19岁及以上的韩国成年人（7261名男性和9917名女性）。上睑下垂定义为边缘反射距离1（MDR 1）低于2毫米。家庭收入和教育水平被用作SES的指标。进行单因素和多因素逻辑回归分析以分析SES与上睑下垂患病率之间的关系。
家庭收入与女性上睑下垂患病率呈负相关[调整后的优势比（aOR）及相应的95%置信区间（95%CI）为1.894（1.336，2.685）]，教育水平与男性和女性的上睑下垂均呈负相关[aOR及95%CI分别为1.572（1.113，2.219）和1.973（1.153，3.376）]。在调整家庭收入和教育水平后，低SES仅与女性上睑下垂的高患病率相关。
在上睑下垂患病率方面发现了女性中的社会经济差异。确实，未来采用前瞻性设计来确定SES与上睑下垂之间因果关系的研究可能会将SES确定为这种情况的一个风险因素。
