The aim of this study was to determine the association between, smoking, exercise, sex, and dietary carotenoids ($\alpha$-carotene, $\beta$-carotene, $\beta$-cryptoxanthin, lutein + zeaxanthin, lycopne) intake in Korean middle-aged adults. Food-frequency questionnaire were analyzed from 304 healthy adults (115 men, 189 women) aged 20 - 59. The self-administered questionnaire contained subject s habitual diet and alcohol intake were the previous 3 months. Data on frequency of 102 foods, including vegetables, fruits, beverages and legumes were analyzed. Total dietary carotenoids intake were 27.13 $\pm$ 3.09 mg/d for men and 26.71$\pm$ 2.82 mg/d for women. It was found that smoking had no significant contribution to the dietary intake of carotenoids. Among other lifestyle factors that had significant correlation was the amount of exercise time. The increases in exercise time was associated with increase in carotenoids intake (r= 0.121, p : 0.04). The major contributors of $\alpha$-carotene and $\beta$-carotene were carrots consumed as single-food item or carrot juice. Lutein and Zeaxanthin intake mainly came from spinach and most lycopene intake was derived from tomato products not fresh tomatoes. Persimmon was the major contributor of $\beta$-cryptoxanthin. These findings provide valuable information on understanding the unique pattern of dietary intake of Korean, which might help identify the risks for developing various diseases.

This study surveyed 150 men aged 30 to 50, a demographic which seborrheic dermatitis is common. The time of day one shampoos and recurrent fatigue were found to have a statistically significant impact on symptoms contributing to the main causes of seborrhea, including itchiness, excessive oil, acne, and redness on the scalp (p<0.01). Study results confirm lifestyle and shampoo habits, such as the frequent sense of fatigue, a routine work schedule, susceptibility to stress, the time of day one uses shampoo, and whether hair styling products are used, affects seborrheic scalp disease. This study found seborrheic scalp disease for office workers primarily resulted from shampoo habits, rashes were predominantly caused by a failure to rinse shampoo and dry hair completely, while secondary aggravating factors included irregular work schedules, recurrent tiredness, and chronic stress.

Benign prostatic hyperplasia (BPH) is the most common prostate disease in middle aged and elderly men. Therefore, identifying risk factors for BPH is crucial for understanding the etiology and for undertaking interventions or targeting strategies. The survey was carried out in two steps: first, pilot study was conducted prior to the main study in order to estimate baseline characteristics. Second, main study investigated prevalence and risk factors of BPH by clinical diagnostic tests and questionnaire. A total of 641 male aged 50-79 years participated in this community-based cross-sectional study. Using 24 hour recall of food consumption, we found that animal fat intakes increased the risk of BPH with adjusted for age, chronic bronchitis, PSA level, drinking frequency, and excercise frequency (odds ratio 1.84,95% confidence interval 1.10-3.06) . Although BPH has been considered as unavoidable disease with advancing age, if these dietary risk factors are clearly identified, it can be prevented effectively by laying special emphasis on those at risk.

Objectives: This study was to examine the association between structural and functional characteristics of social network and self-rated health in middle-aged Korea population. We also explored gender difference in the relationship between social network and health. Methods: Data were collected from individuals aged 40-69 years old participating in the 2005 survey for the Korean Genome & Epidemiology Study. We examined the association between social network, social support, social conflict and self-rated health using multiple logistic regression analysis stratified by gender. Results: The extent and contact frequency of close people, and social participations were associated by not only the positive function but also the negative function of social network. Both the positive and negative functions of social network affected self-rated health. The relationship between the function of social network and health showed a gender difference: only positive function was significantly associated with health in men while only negative function had significant relationship with health in women. Conclusions: Social support and social conflict affected the health in both genders through different ways. The ambivalent effect of social network on health should be explored further.

BACKGROUND/OBJECTIVES: The branched-chain amino acids (BCAA), including isoleucine, leucine, and valine, promote muscle protein synthesis. However, obesity may interfere with protein synthesis by dysregulating mitochondrial function in the muscles. This study aimed to examine the association between dietary intake levels of BCAA and skeletal muscle mass index (SMI) in middle-aged participants, and the effect of obesity/abdominal obesity on this association. SUBJECTS/METHODS: The data of 3,966 men and women aged 50-64 years who participated in the 2008-2011 Korea National Health and Nutrition Examination Survey were analyzed. Intake levels of energy-adjusted dietary amino acids were obtained using a 24-hour dietary recall. SMI was calculated by dividing the appendicular skeletal muscle mass by body weight (kg) and multiplying the result by 100%. Multivariable general linear models were used to analyze the association of dietary BCAA intake levels with SMI. RESULTS: The beneficial effects of energy-adjusted dietary BCAA intakes on SMI were greater in the non-obesity/non-abdominal obesity groups; however, no significant associations were observed in the obesity/abdominal obesity groups (P > 0.05). CONCLUSIONS: Healthy weight and sufficient intake of dietary BCAA are recommended to maintain muscle mass.

Objectives: Much attention has been paid to sleep apnea syndrome (SAS) in the elderly because of its high prevalence. It is expected that SAS in the elderly has both similarities and differences compared to SAS in the young or middle-aged populations. The aim of this study was to elucidate the characteristics and consequences of SAS in the elderly. Methods: In this study we included 210 young or middle-aged adults between 23 and 59 years (20 women and 190 men) and 65 older adults between 60 and 83 years of age (16 women and 49 men). Respiratory disturbance indices (RDIs) of the study subjects were more than 5 in an overnight polysomnography. They completed the Epworth Sleepiness Scale (ESS) and Pittsburgh Sleep Quality Index (PSQI). Informations about body mass index (BMI), neck, waist, and hip measurements, and blood pressure were obtained. Results: No difference was observed between older adults with SAS (older SAS) and adults aged under 60 with SAS (SAS aged under 60) in RDI, apnea index, % time of oxygen saturation less than 90%, and PSQI. Obstructive apnea index and oxygen desaturation index (ODI) were lower in older SAS. Compared to SAS aged under 60, lowest oxygen saturation and central apnea index were higher in older SAS, but they were statistically not significant. BMI and neck circumference were significantly lower in older SAS compared to SAS aged under 60. Diastolic blood pressure was lower in older SAS compared to SAS aged under 60 with no difference in systolic blood pressure. Older SAS showed lower scores in ESS than SAS aged under 60. Significant correlation was observed between RDI and BMI in SAS aged under 60, but not in the case of older SAS. The relationships between RDI and neck circumference, systolic and diastolic pressure, and ESS were similar. Conclusions: The elderly with SAS were not over-weight and there was no relationship between body weight and the severity of SAS. Also, the behavioral and cardiovascular effects of SAS were not marked in the elderly, which might be partly explained by decreased ODI and relatively higher lowest oxygen saturation in older SAS. The normal aging process, aside from increased body weight, might contribute to the development of SAS in the elderly with modest complications.

Objectives: Obstructive sleep apnea (OSA) is prevalent disorder, particularly among the middle-aged. In this study, we report a new approach to improve OSA using oriental medicine and acupuncture. Methods: Three men diagnosed with OSA were enrolled in this study. They took oriental medicine 3 times a day and were given acupuncture twice a week for about 4 months. Results: We analyzed apnea-hypopnea index (AHI), oxygen desaturation index (ODI), average saturation (AS) and lowest saturation (LS) before and after treatment. AHI highly decreased in all patients and ODI also decreased in two of the three patients. Conclusions: These results indicate that oriental medicine and acupuncture therapy was effective in the improvement of OSA. Further study in a larger group with severity grades is recommended.

Sleep disordered breathing is highly prevalent in the elderly and affects older men and women similarly. Nocturia, cardiovascular diseases, cognitive impairment, traffic accidents and repeated falls are common manifestations of sleep apnea in the elderly and sleep study may be indicated in these patients. When a sleep study is planned, reliable markers of respiratory efforts and a tibial EMG should be included because central sleep apneas and periodic leg movements are common in the elderly patients. Although cardiovascular morbidity and mortality seem to be lower in the elderly than in middle-aged adults, these may not be as low as commonly believed. Excessive daytime sleepiness, cognitive dysfunction and nocturia can be improved by effective treatment with continuous positive airway pressure and a therapeutic trial should be recommended to all symptomatic patients. It is still unclear whether sleep apnea in older adults is a specific entity or the same disease as in younger adults. Further clinical research is warranted.

Multiple symmetrical lipomatosis (MSL), also called Madelung's disease, is a rare disorder of unknown etiology and characterized by abnormal accumulation of large subcutaneous fatty masses in neck, shoulder, and upper trunk. MSL has known to predominantly affect middle-aged men with a history of alcoholism. Although the clinical course of MSL is considered to be slowly progressive, in advanced stage, fatty masses in the neck may compress the upper aerodigestive tract, resulting in dyspnea and dysphagia. The treatment of MSL is surgical resection, but radical excision is very difficult and recurrence after surgery is frequent. We report the case of 55-year-old man with long lasting MSL, which caused severe airway obstruction. This patient was admitted with progressive dyspnea and massive accumulation of fat around the vocal cord that was detected on a neck CT scan. This abnormal fatty infiltration in supraglottic region caused upper airway obstruction.
