This study investigated the relationship between smoking and depression and anxiety using data froma nationwide survey representing Korean adolescents. Subjects were 6,489 adolescents in middle and high school (age 13-18) who had participated in the 2011 Korean Study of Promotion Policies on Children and Adolescents-Mental Health (KSPCAM). Daily smoking number of times for current smokers was classified as 1-2 times, 2-4 times and over 5 times. The odds ratio for the statistical test was presented using hierarchical logistic regression.When adjusted for covariates (gender, age, household economy, type of residing city, type of school, school record, satisfaction with school life, subjective health status, satisfaction with relationship with parents, and drinking experience), smokers more significantly likely to have depression (OR = 1.27, 95% CI [1.02-1.57]), and anxiety (OR = 1.49, 95% CI [1.14-1.96]) than non-smokers (p < 0.05). In addition, adolescents who smoke more than 5 cigarettes a day were 1.5 times more likely to have depression (OR=1.48, 95% CI [1.13-1.92]) and anxiety (OR=1.49, 95% CI [1.07-2.08]) than those who do not smoke. Smoking in adolescence was found to be significantly related with depression and anxiety. To promote the mental health of adolescents, effective smoking cessation programs are required. © 2015 Byeon.

Purpose Although distortion of weight perceptions has been known as a risk factor for adolescent depression, little has been known about the relationship between weight misperception patterns and depressive symptoms. This study explored the relationship between distortion of weight misperception patterns and depressive symptoms in Korean adolescents. Methods The subjects of this study were 109,373 middle school students who participated in the Korea Youth Risk Behavior Web-based Survey (KYRBWS) from 2011 to 2013. By comparing the difference between Body Mass Index (BMI) and subjective perceptions of body weight, misperceptions of weight were classified into two categories: misperception of underweight and misperception of overweight. Results When confounding variables were adjusted, the results of the logistic regression analysis revealed that male students who perceived themselves as underweight despite their normal weight were 110% more likely to have depressive symptoms (OR = 1.10, 95%CI: 1.03-1.18) than male students with accurate weight perceptions. On the contrary, for female students, misperceptions of underweight had no significant relationship with depression symptoms. Regardingmisperceptions of overweight, female students who perceived themselves as overweight despite their normal weight were 107% (OR = 1.07, 95% CI: 1.02-1.11) more likely to have depressive symptoms than female students with accurate weight perceptions. Moreover, female students who perceived themselves as overweight when they were underweight were 137% (OR = 1.37, 95% CI: 1.18-1.58) more likely to have depressive symptoms. Conclusion Male students who underestimate their body weight and female students who overestimate their body weight were at a greater risk of depression emotions than students with accurate weight perceptions. © 2015 Haewon Byeon.

Objective: Studies on alcohol consumption and benign laryngeal disease (BLD) in the general population are rare. The aim of this study was to investigate the relationship between alcohol consumption and BLD in the Korean general population. Study Design: This was a cross-sectional study of a national health survey. Materials and Methods: Subjects were 3141 noninstitutionalized civilian adults older than 19 years (1313 men and 1828 women) who completed the laryngeal examination of the Korea National Health and Nutrition Examination Survey of 2008. Frequency of drinking was classified into less than once per week, two to three times per week, and more than four times per week. Binge drinking was defined as five or more drinks (≥61 g of alcohol) per episode for men and as four or more drinks (≥41 g of alcohol) per episode for women. Poisson regression analyses were conducted to examine the relationship between alcohol drinking and BLD. Results: Adjusting for covariates (age, sex, income, level of education, occupation, and cigarette smoking), it was found that those who drank more than four times a week, compared with those who drank less than once per week, were more likely to have BLD (risk ratio = 2.15, 95% confidence interval: 1.01-4.59, P < 0.05). However, the amount of alcohol consumed was not associated with BLD. Conclusions: Frequent drinking (ie, more than four times a week) was found to be a risk factor for BLD. © 2014 The Voice Foundation. Source

The purpose of this study was to determine the influence of functional electrical stimulation (FES) applied to the tibialis anterior and gluteus medius muscles on the improvement of the spatiotemporal parameters of gait in individuals with a hemiparetic stroke. Thirty-six patients who had suffered a hemiparesis post stroke were enrolled in this study. The participants walked at a self-selected velocity on three different FES applications: (1) FES-triggered gait on the gluteus medius in the stance phase and the tibialis anterior in the swing phase (GM. +. TA), (2) FES-triggered gait on the tibialis anterior in the swing phase (TA only), and (3) gait without FES-triggered (Non-FES). FES was triggered when the heel in the affected lower limb was placed in contact with an on or off foot switch sensor. The effect of FES applications was assessed using GAITRite for spatiotemporal data. The gait speed, cadence, and stride length were significantly higher under the GM. +. TA condition than under the TA only and None-FES conditions. The gait speed, cadence and stride length were increased significantly in the TA only condition compared with the Non-FES condition. The double support time and gait symmetry were significantly improved in the GM. +. TA condition compared to the TA only and Non-FES conditions. These findings suggest that walking with FES of the gluteus medius in the stance phase and tibialis anterior in the swing phase can improve the spatiotemporal parameters of gait in individuals with hemiparetic stroke. © 2012 Elsevier B.V.

Objective: This study investigated the prevalence of perceived dysphonia and its correlation with the prevalence of clinically diagnosed laryngeal disorders. Methods: Subjects were 8713 non-institutionalized civilian adults over the age of 19 (3810 men and 4912 women) who completed the laryngeal examination of the fifth Korea National Health and Nutrition Examination Survey. A Poisson regression was used to examine the association between perceived dysphonia and laryngeal disorders. Results: Adjusting for covariates (age, sex, education level, income, occupation, alcohol drinking, and self-reported health status), those with perceived voice problems were 4.8 times (OR = 4.75, 95% CI, 3.77-5.99) more likely to have laryngeal disorders than those without voice problems. In particular, the vocal fold pathology correlated with perceived dysphonia was: vocal fold nodules (OR = 5.32, 95% CI, 3.43-8.26), vocal polyps (OR = 3.73, 95% CI, 1.57-8.86), vocal cysts (OR = 11.97, 95% CI, 1.97-72.72), Reinke's edema (OR = 9.27, 95% CI, 4.77-18.00), laryngeal paralysis (OR = 3.58, 95% CI, 1.56-8.26), laryngeal granulomas (OR = 4.31, 95% CI, 1.01-18.80), epiglottic cyst (OR = 2.94, 95% CI, 1.21-7.13), and laryngitis (OR = 4.07, 95% CI, 2.91-5.69). Conclusion: People with self-perceived dysphonia had a high risk of laryngeal disorders. © The Author(s) 2015. Source
