Blepharoptosis among Korean adults: age-related prevalence and threshold age for evaluation.

ABSTRACT: BACKGROUND:To evaluate the prevalence of blepharoptosis among Korean adults and the characteristics of blepharoptosis patients, and to determine an appropriate age threshold for recommending blepharoptosis evaluation. METHODS:The Korean National Health and Nutrition Examination Survey (KNHANES-V) was conducted in 2010-2012. We extracted data on 17,878 Korean adults aged more than and equal to 19?years included in KNHANES-V, and determined blepharoptosis prevalence according to age, to determine the cutoff age for recommending blepharoptosis evaluation. We also determined the possible association between blepharoptosis and obesity parameters, such as body mass index (BMI) and waist circumference (WC). RESULTS:There was astrong association between older age and the prevalence of blepharoptosis. The cutoff age for recommending blepharoptosis evaluation was 63?years for males, 70?years for females, and 66?years for all patients. Patients with a high BMI and large WC had a higher prevalence of blepharoptosis in all age groups except for those aged over 80?years. The association of blepharoptosis with BMI according to age group showed that in the 50-59 and 60-69?years age groups, blepharoptosis prevalence and BMI were higher. However, in the 70-79 and 80-89?years age groups, extremely obese patients (BMI?>?30) showed a decreased blepharoptosis prevalence. CONCLUSIONS:Moderate to severe blepharoptosis can result in poor visual function and exacerbate headaches and depression, leading to decreased quality of life. This study proposed an appropriate age threshold for recommending evaluation of patients with blepharoptosis among the general population of Korea.

Project description:BackgroundIn evaluating hearing disability in medicolegal work, the apportionment of age- and gender-related sensorineural hearing loss should be considered as a prior factor, especially for the elderly. However, in the literature written in the English language no studies have reported on the age- and gender-related mean hearing threshold for the South Korean population.ObjectiveThis study aimed to identify the mean hearing thresholds in the South Korean population to establish reference data and to identify the age- and gender-related characteristics.MethodsThis study is based on the Korea National Health and Nutrition Examination Survey (KNHANES) 2010-2012, which was conducted by the Korean government, the data of which was disclosed to the public. A total of 15,606 participants (unweighted) representing 33,011,778 Koreans (weighted) with normal tympanic membrane and no history of regular or occupational noise exposure were selected and analyzed in this study. The relationship between the hearing threshold level and frequency, age, and gender was investigated and analyzed in a highly-screened population by considering the sample weights of a complex survey design.ResultsA gender ratio difference was found between the unweighted and the weighted designs: male:female, 41.0%: 59.0% (unweighted, participants) vs. 47.2%:52.8% (weighted, representing population). As age increased, the hearing threshold increased for all frequencies. Hearing thresholds of 3 kHz, 4 kHz, and 6 kHz showed a statistical difference between both genders for people older than 30, with the 4 kHz frequency showing the largest difference. This paper presents details about the mean hearing threshold based on age and gender.ConclusionsThe data from KNHANES 2010-2012 showed gender differences at hearing thresholds of 3 kHz, 4 kHz, and 6 kHz in a highly-screened population. The most significant gender difference in relation to hearing threshold was observed at 4 kHz. The hearing thresholds at all of the tested frequencies worsened with increasing age. The mean hearing thresholds suggested in this study will be useful for the formulation of healthcare-related hearing policies and used as reference data for disability ratings for hearing loss due to various causes.
