Binge Drinking and Its Relation to Metabolic Syndrome in Korean Adult Men

BackgroundIt is reported that heavy drinking increases the risk of metabolic syndrome. But there have been few studies on the relationship between the intensity of drinking and metabolic syndrome when drinking the same amount of alcohol. This study aimed to assess the relationship between the frequency of binge drinking and metabolic syndrome in Korean adult men.MethodsFrom the database of the 4th and 5th Korea National Health and Nutrition Examination Survey conducted in 2007-2010, data of 8,305 adult men (≥19 years of age) was included in this analysis. Cross-sectional relationship between the frequency of binge drinking and metabolic syndrome was investigated adjusting for pure alcohol consumed per day.ResultsAdjusting for various confounders including pure alcohol consumed per day, the adjusted odds ratio for metabolic syndrome in those in higher frequency (more than 1/wk) binge drinking group was 1.62 (95% confidence interval, 1.30 to 2.03; P for trend = <0.001) compared to those in the non-binge drinking group. Through analysis of the relationship between pure alcohol consumed per day and metabolic syndrome, it was found that pure alcohol consumed per day had a positive relation to metabolic syndrome in the higher frequency binge drinking group (P for trend = 0.041). The relationship was inverse in the non-binge drinking group (P for trend = 0.002).ConclusionOur study found a positive relationship between frequency of binge drinking and metabolic syndrome in adult men. And the effect of drinking on metabolic syndrome may depend on the frequency of binge drinking. Further studies are required to confirm this association.

Importance of fat mass and lean mass on bone health in men: the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV)

This study was aimed to evaluate the association between body composition and bone health. High lean mass and low fat mass have protective effects on bone health in men representative of the national population. The aim of this study was to evaluate the association between body composition (fat mass and lean mass) and bone health in men. Totally, 3,945 men (age ≥ 20 years) from the fourth Korean National Health and Nutrition Examination Survey of 2008-2009 (KNHANES IV) were included in this study. Body composition and bone mineral densities (BMDs) were measured using dual energy X-ray absorptiometry. Osteopenia or osteoporosis was identified on the basis of the World Health Organization T-score criteria. Multiple linear regression analyses showed that BMDs of the whole body, femoral neck, and lumbar spine were positively associated with lean mass and negatively associated with fat mass, after controlling for body weight and other potential confounders. Subjects with more fat mass or less lean mass, categorized according to quartiles of fat mass and lean mass, had higher odds of having osteopenia or osteoporosis, as shown by multivariable logistic regression (P for trend <0.001). High lean mass and low fat mass have protective effects on bone health in a population of Korean adult men. Fat mass appears to exert a detrimental effect on BMD, in contrast with the positive weight-bearing effect. Body composition seems to be a more important determinant for bone health than simple body weight.

Relations of Drinking Motives and Alcohol Consumption in Korean Male Office Workers

The relation between alcohol consumption and drinking motives was investigated among male office workers, 270 adult Korean men (M age = 38.6 yr., SD = 9.2) who were current drinkers. Heavy alcohol drinking was reported by 30.7% of the participants. Social motives had the highest mean score on the drinking motive questionnaire. Participants ages 20 to 29 yr. were more likely to drink for social and enhancement motives than those ages 40 to 49 yr. Participants without spouses reported greater importance of social motives and enhancement motives than those with spouses. Social motives, coping motives, and age-predicted alcohol consumption were regressed on the Quantity-Frequency index. This index score explained 30.5% of the variance in social motives, coping motives, and age. These findings suggest that there is high prevalence of heavy alcohol consumption among Korean office workers, who were likely to drink alcohol to increase sociability and reduce tension.

Pigmentation above the constitutive level: An indicator of excimer laser radiation‐induced erythema in Koreans

Ultraviolet (UV) irradiation induces skin erythema, but it is not clear which factors have the greatest effects on UV sensitivity. Six healthy Korean adult men were enrolled and their melanin index (MI) and increment of erythema index (ΔEI) were measured. In each individual, 12 different sites were selected and 36 spots were irradiated with a single shot of monochromatic excimer laser with a dose of 350 mJ/cm(2) . The sites were categorized into three groups based on the cumulative sun exposure: UZ, unexposed zones; FEZ, frequently exposed zones; and IEZ, intermittently exposed zones. The sun exposure indexes (SEI) were also calculated based on previously described methods. ΔEI, MI and SEI were measured and calculated. The ΔEI of UZ was significantly higher than that of FEZ, but lower than that of IEZ. In general, there was a significant relationship between ΔEI and MI (R(2) = 0.135). However, IEZ did not show significant results. In contrast, there was a stronger relationship between ΔEI and SEI (R(2) = 0.344). Overall, the values were significantly higher for the SEI (0.541 [UZ], 0.281 [IEZ] and 0.228 [FEZ]) than for MI (0.311 [UZ], 0.011 [IEZ] and 0.073 [FEZ]). There were significant site variations in UV sensitivity along with skin pigmentation. In addition, significant differences were observed according to the exposure frequency. The SEI was found to be strongly correlated with UV sensitivity. These results suggest that the induced level of pigmentation above the constitutive level will be a better indicator for UV sensitivity than baseline MI.

Independent and Joint Associations of Cardiorespiratory Fitness and Muscle Fitness with Metabolic Syndrome in Korean Men

Higher cardiorespiratory fitness (CRF) and muscle fitness (MF) attenuate metabolic syndrome prevalence in men. However, associations of CRF and MF with metabolic syndrome were poorly understood in South Korean men. Therefore, this study aimed to examine the independent and joint associations of CRF and MF on metabolic syndrome prevalence in Korean men. Korean men (n=1,097, mean age=44 years) were recruited from the central areas of South Korea for this Preventive Health Study (PHS) between May, 2007, and October, 2008, and they underwent a health examination, maximal treadmill test, and five different muscle fitness tests for this study. From our data, separate age- and current smoking-adjusted logistic regression models revealed a graded inverse association of metabolic syndrome prevalence with CRF (P<0.0001) and MF (P<0.0001). The association of MF with metabolic syndrome remained significant and became attenuated with further adjustment, for CRF (P=0.02). However, the association of CRF with metabolic syndrome remained unchanged when adjusted for MF (P<0.0001). In the joint analysis using the low-strength and CRF unfit group as the baseline, the odds ratios (95% confidence intervals) for having metabolic syndrome were 0.52 (0.26-1.05) for the high-strength and CRF unfit group, 0.39 (0.24-0.65) for the low-strength and CRF fit group, and 0.28 (0.17-0.46) for the high-strength and CRF fit group. Both cardiorespiratory fitness and muscle fitness showed independent and joint inverse associations with metabolic syndrome prevalence in Korean adult men.

The Effect Of Cardiopulmonary Fitness On Colorectal Polyps Incidence

PURPOSE: The results of previous epidemiologic studies showed that dietary and life style factors are associated with colon polyps. Physical activity is associated with a reduced risk of colon cancer, but the effect of activity on colorectal adenomas, which are precursors to colon cancer, is uncertain. Despite the high prevalence of colon polyps, little is known about its risk factors in Korean male adults. The aim of this study was to investigate the relationship between cardiopulmonary fitness(VO2max) and the presence of colorectal polyps. METHODS: In 1075 subjects aged between 40 and 60years, colonoscopy was performed at Asan Medical Center Health Promotion Center(HPC) from October 2005 to august 2007. All subjects were identified on routine checkup at the HPC. We selected data from subject who did stress test with gas analyzer on the treadmill for cardiopulmonary fitness(VO2max). For getting Odds ratio between fitness level and incidence of polyps, we classified fitness level to quartile. Also, we compared fitness level with polyp size above 0.5cm and smaller. All data were evaluated retrospectively. Drinking, smoking and other confounding factors were assessed by self-administered questionnaire. After adjusting for age, sex, physical activity, obesity, and total energy intake, data was analyzed by logistic regression. RESULTS: For the incidence of polyps and cardiopulmonary fitness(VO2max), the incidence rate was lowered with subjects who had High fitness in their fourties but fifties and sixties. The Odds ratio was 2.124(CI:1.105-4.084, P=0.024) in the lower fitness group(lower 25 percentile) compared with high fitness group(upper 25 percentile group). Also, we evaluated relationship between polyps size above 0.5cm and Cardiopulmonary fitness. We could get the same result as polyps incidence ratio at only fourties. Unfourtunately, no significance was detected from age fifties and sixties. CONCLUSIONS: High cardiopulmonary fitness is associated with a reduced incidence of colorectal polyps among Korean adult men during their fourties

MP-19.16: The Correlation between Urinary pH and Metabolic Syndrome in the Adult Korean Men Who Visited Health Promotion Center

Low urinary pH (≤5.5) was the most powerful risk factor of idiopathic uric acid stone and an acidic urine has been described as a renal manifestation of the metabolic syndrome. We evaluated the association between urinary pH and metabolic syndrome in the ostensively healthy adult Korean men.

Relationships between body mass index, diabetes, and blood glucose level in South Korean adults: 2005 Korea National Health and Nutrition Survey

How to define overweight and obesity among Asian individuals has not yet been firmly decided. Western countries have been using the general criteria for overweight (BMI &gt; 25) and obesity (BMI &gt; 30) with Asian populations in their country, while WHO and Asian countries have recommended or adopted lower BMI cutoff points for overweight and obesity. More data on relationships between BMI, morbidity, and mortality in Asian populations have been called for to decide which criteria are more appropriate. This study examined relationships between BMI, diabetes, and fasting blood glucose level in Koreans using 2005 Korea National Health and Nutrition Survey. The relationships found in the 2005 dataset were compared to those in 1998 dataset to determine whether the relationships were affected by nutrition transition occurred in Korea. The average BMI of Korean adult (age &gt; 20) men and women were 23.9 ±0.1 kg/m2 and 23.3±0.1 kg/m2, respectively. According to the WHO Asian Pacific criteria for overweight (23kg/m2=BMI=25kg/m2) and obesity (25kg/m2 =BMI), 23% of men and 19.9% of women were grouped as overweight, while 27.4% of men and 22.5% of women as obese. The diabetes prevalence was on average 51.7 per 1000 persons with men showing higher prevalence than women. BMI and the diabetes prevalence showed a positive relationship, and the nature of the relationship appeared slightly different from those found in 1998 dataset. The difference, albeit small, should be examined further and followed up to determine whether the relationships are fixed.

The Correlation between Metabolic Syndrome and Urinary pH in Adult Korean Men Who Visited a Health Promotion Center

Purpose: Low urinary pH is a risk factor for uric acid stones, and acidic urine has been described as a renal manifestation of the metabolic syndrome. We evaluated the association between metabolic syndrome and urinary pH in adult Korean men who visited a health promotion center. Materials and Methods: From 2004 to 2008, a total of 18,513 adult men who visited our health promotion center were enrolled in this study. The relation between urinary pH and various parameters associated with the metabolic syndrome were evaluated. Results: The average age was 45.6 years (range, 18-95 years), and 4987 men (26.9%) were classified as having the metabolic syndrome. The mean urinary pH of the metabolic syndrome group was 5.91, which was significantly lower than that of the normal group (6.08). In univariate and multivariate analysis, body mass index, serum triglyceride, and blood sugar were negatively correlated with urinary pH (p25 kg/m2), hypertriglyceridemia (150 mg/dl), high fasting glucose (110 mg/dl), and low high-density lipoprotein cholesterol (5.5). Conclusions: Metabolic syndrome was related to lower urinary pH in ostensively healthy adult Korean men. Further studies are needed to elucidate the exact mechanism responsible for the lower urinary pH in individuals with the metabolic syndrome.

Testicular Volume of Korean Young Adult Men as Measured by Ultrasonography: Relationship with Body Mass Index

Purpose: Testicular volume is one of the important indices that represent the reproductive ability of adult males. In previous studies, however, testicular volume was measured by manual palpation or orchidometer, resulting in inaccuracy or subjectivity. Accordingly, the need for accurate data on the size of the testes is increasing, and we conducted testicular volume measurements by using scrotal ultrasonography. We investigated the relationship between testicular volume and body weight, height, and body mass index (BMI). Materials and Methods: The testicular volumes of 1,002 young adult Korean men were measured for length, width, and thickness with ultrasonography, and data on BMI were collected conventionally. The correlation between testicular volume and BMI was analyzed with one-way ANOVA and Student's t-test. Results: The mean age of the young men was 23.02±2.53 years. The mean testicular volume was 18.09±3.79 cc on the left and 18.26±3.21 cc on the right. Testicular volume was directly proportional to body weight, height, and body mass index. Conclusions: The testicular volume of Korean young adult men was about 18.17 cc. Testicular volume has a weak direct correlation with body weight, height, and body mass index.

Alcohol Consumption, Liver Enzymes, and Prevalence of Metabolic Syndrome in Korean Adult Men

Metabolic syndrome is associated with an increasing incidence of diabetes and cardiovascular disease. The relationship between the amount of alcohol consumption and the prevalence of metabolic syndrome is controversial. Our study was performed to evaluate the relationship between alcohol consumption and the prevalence of metabolic syndrome in Korean men. Also we examined the correlation of liver markers, including alanine transaminase (ALT) and γ

Additive effect of interleukin-6 and C-reactive protein ( CRP) single nucleotide polymorphism on serum CRP concentration and other cardiovascular risk factors

Background Serum C-reactive protein (CRP) levels, closely associated with cardiovascular disease (CVD) risk are influenced by CRP or interleukin-6 ( IL-6) single nucleotide polymorphism (SNPs). However, it is still controversial. Therefore, we investigated the association of IL-6/CRP SNPs and serum CRP levels or other CVD risk factors in healthy adult Korean men. Methods In healthy adult men (age ≥ 20 years, n = 677), we genotyped IL-6−572C > G and CRP SNPs (− 717G > A, 1444C > T, 2147A > G) and measured anthropometric parameters, lipid profile, serum levels of CRP and IL-6 and insulin resistance. Results At IL-6−572C > G ( n = 677), subjects with G/G genotype ( n = 42) showed higher concentrations of CRP ( P = 0.027) and IL-6 ( P = 0.028) as compared with C allele carriers after age-adjustment (C/C: n = 371, C/G: n = 264). Fasting insulin and homeostatis model assessment insulin resistance (HOMA-IR) were also higher in G/G genotype. However, there were no significant differences in other metabolic biomarkers. Among 677 study subjects, 676 were genotyped at CRP−717G > A (G/G: n = 513, G/A: n = 150, A/A: n = 13), 672 at CRP+1444C > T (C/C: n = 580, C/T: n = 85, T/T: n = 7), and 668 at CRP+2147A > G (A/A: n = 273, A/G: n = 296, G/G: n = 99). There were no significant differences in CRP concentrations and other markers related to CVD risk according to each CRP SNP genotype. However, we could find the additive gene–gene interaction between IL-6−572C > G and CRP SNPs on CRP concentration; subjects with the ‘G/G’ at IL-6−572 showed the highest CRP levels when they have variant allele at CRP SNPs after adjusted for age, body mass index, cigarette smoking and alcohol drinking (− 717G > A: F = 7.806, P = 0.005; CRP + 1444C > T: F = 8.398, P = 0.004; and CRP + 2147A > G: F = 7.564, P = 0.006, respectively) Particularly, G allele carriers at CRP+2147A > G in subjects with IL-6−572G/G showed highest HOMA-IR ( F = 9.092, P = 0.003). Conclusion The present data showed that serum CRP levels and other CVD risk factors appeared more influenced by IL-6−572C > G rather than CRP SNPs (− 717G > A, 1444C > T, and 2147A > G), however CRP levels and insulin resistance may be additively affected by IL-6−572 and CRP SNP, particularly when subjects with G/G genotype at IL-6−572 have allele variant at CRP SNPs.

Influence of Lifetime Sports Activity Based on a Ground Reaction Force on Bone Mineral Density in Korean Adults

The purpose of this study was to retrospectively describe the childhood sports activity level of Korean adult men and women and to determine whether a higher level of childhood sports activity was positively associated with adult bone mineral density. A cross-sectional study of 100 Korean men (n=40) and women (n=60) was completed. Participants completed a detailed lifetime sports activity questionnaire and had their bone mineral density of the femur and lumbar spine measured using dual energy x-ray densitometry (DEXA). All sports activities were classified into four categories of peak strain score on the basis of ground reaction forces (GRF). During the age of high school, women and men who participated in a high intensity sports activity demonstrated higher bone density in the femur site after adjustment for the effects of body weight, fat body mass, lean body mass, the level of calcium intake, and breast feeding period than those who did not participate in sports activity at all. These results highlight the need to participate in high intensity sports activity during high school age as a means of increasing peak bone mass in the femur site.

단층촬영법에 의한 한국 성인의 성별, 연령 그리고 과체중 분류에 따른 복부부위의 체지방 분포의 차이

This study was performed to compared of subcutaneous and visceral fat distribution according to sex, age and overweight. The subjects were composed of 234(male:114, female：120) Korean adult men and women who were 20-81 years old. Abdominal fat depots were evaluated by computed tomography at one abdominal level. The population sample was categorized according to sex, age( age intervals : 20-39, 40-59, 60 more yr) and body mass index(BMI≤26 and BMI〉26.1; weight/hight2). The results were as follows： 1. Total fat and visceral fat area at abdominal level increased with aging in both male and female group. However Subcutaneous fat area decreased during aging in male group, and increased in female group. 2. 20-39 yr age group had higher subcutaneous fat area than the other groups, However Over the age of 60 had higher visceral fat area than the other groups in both male and female group. 3. The rate of S:V at abdominal level decreased during aging in both male and female. 4. Visceral fat area at abdominal level increased with aging in both male and female group by BMI26.1, However Subcutaneous fat area was no difference among three group in female, and increased during aging in male. 5. Subcutaneous fat and visceral fat area at abdominal level increased during aging in both male and female group by BMI≥26.
