Studies on the risk factors of voice disorders in Korean adults are rare. I evaluated the association between the duration of self-reported voice problem and voice disorders in Korean adults. Data were from the 2008 Korea National Health and Nutritional Examination Survey. Subjects were 3,135 people (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between the duration of self-reported voice problem and voice disorders. The prevalence of self-reported voice problems was 5.9% among Korean adults. Adjusting for covariates (age, sex, education level, length of employment, tobacco consumption, alcohol consumption, thyroid disorders, pain and discomfort during the last two weeks), self-reported voice problems lasting longer than three weeks were independently associated with functional voice disorders (OR=5.30, 95% CI: 3.30-8.50) and organic voice disorders (OR=4.84, 95% CI: 1.82-12.89). Self-reported voice problems in the past three weeks were significantly associated with functional voice disorders (OR=3.64, 95% CI: 1.84-7.19), but not significantly associated with organic voice disorders. Self-reported voice problems are prevalent among adults. This study highlights that self-perception of a voice problem for more than three weeks is related to functional voice disorders and organic voice disorders.

The purpose of this study was to analyze the association between self-reported voice problems and voice disorders in the Korean adult population. Data were collected from the 4th Korea National Health and Nutritional Examination Survey (2008) from 3,135 subjects (1,310 men and 1,825 women) aged 19 years and older. Multi-nominal logistic regression analyses were used to examine the association between self-reported voice problems and voice disorders in the Korean adult population. Adjusting for covariates (age, sex, education level, job, smoking, alcohol drinking, thyroid disorders, pain and discomfort during the last 2 weeks), self-reported voice problems included independently associated functional voice disorders (OR=4.70, 95% CI: 3.14-7.03) and organic voice disorders (OR=3.89, 95% CI: 1.57-9.65). The results of the present study verified that self-reported voice problems are valuable indicators for voice disorders. Further research is needed to ascertain the effect of self-reported voice problems on voice disorder in adults.

Recent research has identified that self-reported voice problems are a risk indicator for voice disorders. However, previous studies concerning the general population did not take into account the influence of gender on self-reported voice problems. The purpose of the present cross-sectional study was to determine the gender differences in risk factors of self-reported voice problems in the Korean adult population using national survey data. This study utilized data from the Korea National Health and Nutritional Examination Survey 2008. Subjects inclued 3,622 people (1,508 male and 2,114 female) aged 19 years and older living in the community. Data were analyzed using t-test, one-way ANOVA, and multiple logistic regression. The prevalence of self-reported voice problems was 5.9% in males, and 8.1% in females Females had higher incidents of self-reported voice problems than males. Adjusting for covariates, in males, age (OR=2.47, 95% CI: 1.07-5.70), pain and discomfort during the last two weeks (OR=3.64, 95% CI: 2.20-6.01) were independently associated with self-reported voice problems (p<0.05). In women, age (OR=1.96, 95% CI: 1.18-3.26), education (OR=2.09, 95% CI: 1.06-4.12), smoking (OR=2.70, 95% CI: 1.48-4.93), thyroid disorders (OR=2.58, 95% CI: 1.47-4.53), pain and discomfort during the last two weeks (OR=1.75, 95% CI: 1.21-2.54) were independently associated with self-reported voice problem (p<0.05). Self-reported voice problems related risk factors differed according to gender. These findings suggest that there needs to be different program strategies that reflect gender differences in self-reported voice problems.

The purpose of this study was to analyze the association between self-reported voice problem and body mass index. Data were collected from the 5th Korea National Health and Nutritional Examination Survey (2010) from 5,811 subjects(2,503 men and 3,308 women) aged 19 years and olders. chi-square, t-test and multi-nominal logistic regression analysis were used that to compare self-reported voice problem and variable(age, sex, hight, weight, waist measurement, body mass index). body mass index(OR=1.028, 95% CI: 1.003-1.056) was independently associated with self-reported voice problem(p<0.031). also over weight-two step obesity (OR=1.765, 95% CI: 1.036-3.006) were independently associated with self-reported voice problem(p<0.036). The results of comparison verified that body mass index are valuable self-reported voice problem of risk factor. when the evaluation were conducted, what was considered body mass index is needed.

The purpose of this study was to analyze the risk factors of self-reported voice problem. Data were from the Korea National Health and Nutritional Examination Survey 2008. Subjects were 3,600 persons (1,501 men, 2,099 women) aged 19 years and older. A prediction model was developed by the use of a exhaustive CHAID (Chi Squared Automatic Interaction Detection) algorism of decision tree model. In the decision tree analysis, pain and discomfort during the last 2 weeks, age, the longest occupation and thyroid disorders was significantly associated with self-reported voice problem. The findings of associated factors suggest potential ways of targeting counseling and prevention efforts to control self-reported voice problem.

The South Korea has the highest overall smoking rates of male among the thirty member-countries in the Organization for Economic Cooperation and Development. This study was performed to determine the association between amount of smoking and self-reported voice problem in Korean adult population using national survey data. Data were drawn from the Korea National Health and Nutritional Examination Survey 2008. Subjects were 3,600 persons (1,501 male, 2,099 female) aged 19 years and older living in the community. Adjusting for covariates (age, sex, education, income, longest occupation, alcohol drinking, pain and discomfort during the last 2 weeks), Severe smoke (>40.5-55.5 pack year), more than 20 cigarettes per day were independent risk factors for self-reported voice problem. It was found that the number of cigarettes smoked per day (CPD) the proportional increased in risk of voice disorders. These findings suggest that the investigation of CPD are required for effective screening of voice disorder.
