Purpose: This study was to explore the prevalence of alcohol experiences and to identify the expectancy on the effects of alcohol and alcohol knowledge in early adolescents. Method: The cross-sectional survey of 1854 students from seven middle schools in one district of Seoul was conducted by convenience sampling. Alcohol experience and early onset of alcohol use were measured by the Youth Risk Behavior Survey. Alcohol expectancy was measured by an Alcohol Effects Questionnaire. Result: Over sixty five percent of adolescents reported that they had previous drinking experiences. The participants with no alcohol drinking experience had a lower level of alcohol knowledge than those with experience(t=2.73, p=.007). In expectancy on effects of alcohol, girls had a more positive alcohol expectation than boys(t=-2.54, p=.011). Alcohol knowledge negatively correlated with alcohol expectancy(r=-.40 p=.000). In regression of alcohol expectancy, gender and alcohol knowledge were significant predictors explaining 17%. Conclusion: The results support that alcohol expectancy is an important link with early drinking experiences and alcohol knowledge, focusing on the importance of gender differences. Therefore, an alcohol prevention program in early adolescence is needed and should be focused on multidimensionality of the alcohol expectancy with developmental and psychosocial factors for early adolescents.
This study was undertaken to investigate the effect of the levels of dietary Zn and alcohol consumption on lipid metabolism in Sprague-Dawley male rats weighing 80 to 90g for eight weeks. Ninety rats were divided into nine groups according to Zn levels and alcohol consumption such as no alcohol group[low Zn diet group(<1ppm. LZ) control Zn diet group(30ppm. CZ) high Zn diet group(60ppm, HZ)] 10% alcohol consumption group[the same Zn levels as no alcohol group LZLA, CZLA, HZLA] 20% alcohol consumption group[the same Zn levels as no alcohol group, LZHA, CZHA, HZHA] The results obtained were summarized as following : 1) In the serum total cholesterol increased with increasing dietary Zn levels but decreased with alcohol consumption. HDL-cholesterol decreased with alcohol consumption. Triglyce-ride in alcohol group was higher than no alcohol group. In alcohol group triglyceride increased with decreasing dietary Zn levels. 2) In the liver total lipid in alcohol group was higher than no alcohol group HA group showed a significant increase. Triglyceride increased with alcohol consumption. 3) In the serum and liver Zn content increased with increasing dietary Zn levels but decreased with alcohol consumption.
This study was carried out to compare the effect of smoking on dietary habits, nutrient intakes and blood lipid profiles in 173 adult male drinkers. Subjects were classified by two groups, alcohol-only and alcohol-smoking, based on their alcohol or smoking habits. The BMI of the alcohol-smoking group was significantly lower than those of alcohol-only group. In dietary habits, the alcohol-smoking group had higher irregular breakfast and dinner intakes than alcoholonly group (p < 0.05). Plant lipid intake of the alcohol-smoking group was higher than those of alcohol-only group (p < 0.05) and the vitamin C intake of the alcohol-smoking group was lower than those of alcohol-only group (p < 0.05). With regard to the diet quality evaluation of subjects, the alcohol-smoking group showed significantly lower values than alcohol-only group in the nutrient density of carbohydrate, dietary fiber, sodium, potassium, vitamin $B_6$, and vitamin C. Also, with regard to the index of nutrition quality (INQ) and the nutrient adequacy ratio (NAR), the alcohol-smoking group showed significantly lower value than alcohol-only group in vitamin C. With these results, we found that the alcohol-smoking group had lower diet quality evaluation. The results of blood analysis showed that HDL-cholesterol in the alcohol-smoking group was significantly lower than that in the alcohol-only group. In conclusion, the alcohol-smoking group had greater health risk than the alcohol-only group. Particularly, alcohol-smoking caused irregular eating patterns and unbalanced nutrition intakes compared to alcohol-only and also changed blood composition as shown in the decrease of HDL-cholesterol. Besides, the index of coronary heart disease such as AI was higher in both groups suggesting that alcohol-only or alcohol-smoking cause health problems. Since there is the limiting point in which the comparative analysis of non-drinkers and non-smokers is unable to be performed in this study, further wide research is needed on that matter.
This study examined the dual mediating effects of drinking motivation and drinking level between alcohol advertising, alcohol sale promotion marketing exposures, and alcohol-related harms. The survey has been conducted on 2,000 adult men and women aged 20 to 70 years, recruited by an online survey. As a result, it is found that alcohol advertising, alcohol sale promotion marketing exposures, drinking motivation, drinking level, alcohol-related harms appeared more in men than in women. In addition, alcohol advertising, alcohol sale promotion marketing exposures have positive effects on alcohol-related harms. Also, drinking motivation and drinking level partially mediate the effects of alcohol advertising, alcohol sale promotions marketing exposure, and alcohol-related harms. In order to prevent alcohol-related harms, a social environment that causes alcohol-related harms should be tightened regulations about alcohol advertising, alcohol sale promotion marketing exposures. Based on these results, this study discusses that needs the intervention not only personal perception but also social environment and regulations about alcohol advertising, alcohol sale promotion marketing.

Objectives: To explore alcohol perceptions and their association hazardous alcohol use in the populations of Alberta, Canada and Queensland, Australia. Methods: Data from 2500 participants of the 2013 Alberta Survey and the 2013 Queensland Social Survey was analyzed. Regression analyses were used to explore the association between alcohol perceptions and its association with hazardous alcohol use. Results: Greater hazardous alcohol use was found in Queenslanders than Albertans (p<0.001). Overall, people with hazardous alcohol were less likely to believe that alcohol use contributes to health problems (odds ratio [OR], 0.46; 95% confidence interval [CI], 0.27 to 0.78; p<0.01) and to a higher risk of injuries (OR, 0.54; 95% CI, 0.33 to 0.90; p<0.05). Albertans with hazardous alcohol use were less likely to believe that alcohol contributes to health problems (OR, 0.48; 95% CI, 0.26 to 0.92; p<0.05) and were also less likely to choose a highly effective strategy as the best way for the government to reduce alcohol problems (OR, 0.63; 95% CI, 0.43 to 0.91; p=0.01). Queenslanders with hazardous alcohol use were less likely to believe that alcohol was a major contributor to injury (OR, 0.39; 95% CI, 0.20 to 0.77; p<0.01). Conclusions: Our results suggest that people with hazardous alcohol use tend to underestimate the negative effect of alcohol consumption on health and its contribution to injuries. In addition, Albertans with hazardous alcohol use were less in favor of strategies considered highly effective to reduce alcohol harm, probably because they perceive them as a potential threat to their own alcohol consumption. These findings represent valuable sources of information for local health authorities and policymakers when designing suitable strategies to target alcohol-related problems.
The purpose of this study was to investigate the effects of alcohol intake on nutritional intake status among the college students. The subjects were divided three groups; no-alcohol group(n=78), alcohol group(n=113), and high-alcohol group(n=82) according to intake and frequency of alcohol. And they were observed characteristics of alcohol drinking, dietary behavior and attitude, and nutrient intakes using questionnaires. The frequency of skipping meals in breakfast in high-alcohol group were higher than in other two groups(p<0.01). There were no significant differences in frequency of skipping meals of lunch and supper, reason why skipped meals, and total score of dietary attitude among three groups. However, the score of dietary attitude about no heavy drinking and smoking in high-alcohol group was higher than in other two groups(p<0.01). There were significant difference in vitamin B2 intake, alcohol intake, and energy intakes from carbohydrate, lipid, and alcohol among three groups(p<0.05, p<0.05, p<0.01, p<0.05, p<0.05). Compared energy intake of high-alcohol group with other two groups, intake from carbohydrate was low and intakes from lipid and alcohol were high. In the nutrient density, plant protein and carbohydrate in no-alcohol group, lipid and vitamin B2 in alcohol group, and animal lipid in high-alcohol group were highest among three groups. NAR and MAR were not significant difference among three groups except that NAR of P in alcohol group is highest among three groups(p<0.05). In conclusion, students high consuming alcohol have unhealty dietary behaviors in the light of high frequency of skipping breakfast, undesirable dietary attitude of alcohol drinking and smoking, and low energy inake from diet. Therefore, this results should be considered in meal management and nutritional education for student of high alcohol consumption.
The effects of Ganoderma Lucidum consumption (GL) on the liver function and lipid metabolic disorder induced by alcohol consuming were studied in rats using GL powder(1%, 2%, 4%) and 10% ethly alcohol. Thirty-five rats(Sprague-Dawley, male) were divided into five groups and fed experimental diets for seven weeks. The concentrations of serum cholesterol, HDL-cholesterol and triglyceride were the highest in the alcohol group, while the levels were apparently reduced by in groups fed GL. The atherogenic indices(AI) also tended to be higher in the alcohol group. Glutamic oxaloacetic transaminase(GOT) activities were significantly lower in body alcohol + 2% GL and alcohol + 4% GL groups, and glutamic pyruvic transaminase(GPT)activities lower only in the alcohol + 2% GL compared with the alcohol group. Alkaline phosphatase(ALP) activities were not significantly different among the groups. The elevated levels of liver cholesterol and triglyceride due to alcohol consumption, were apparently reduced by GL supplementation. On microscopic observation of liver tissues, fat droplets appeared extensively on the liver-lobule in the alcohol group, while fat droplets appeared only on the central vein in the alcohol + 1% GL group. However, in groups administered 2% and 4% GL, fat droplets appeared similar to the alcohol group. The concentrations of fecal bile acid were significantly increased in groups fed GL. These results indicate that GL exerted some beneficial effects on lipid metabolic disorder caused by long-term alcohol consumption. Thus, it seems that GL may be effective in preventing or curing some aspects of alcohol toxicity. More detailed studies are needed in order to determine proper dietary levels of GL for combating alcohol toxicity.
Objective:Nitric oxide(NO) has been known to be associated with tolerance and preference to alcohol. It has also been known to affect various alcohol drinking behavior, alcohol withdrawal symptoms and alcohol- induced brain damage. The purpose of this study was to determine the difference, among alcohol dependence group, alcohol drinking group and abstinence group, in serum concentration of nitrite, a stable metabolite of NO, and it's relationship to clinical and biochemical markers of alcoholism. Methods:Forty subjects diagnosed as alcohol dependence according to DSM-IV diagnostic criteria were evaluated for the clinical characteristics and biochemical markers of alcohol dependence including nitrite with their CIWA-Ar scores checked just after admission. Thirty-nine healthy controls were also evaluated, divided into twenty-three alcohol drinking group and sixteen abstinence group. Clinical characteristics were evaluated by CIWA-Ar, CAGE and AUDIT questionnaires. Aspartate aminotransferase(AST), alanine aminotransferase (ALT), gamma glutamyltransferase(GGT) and mean corpuscular volume(MCV) were used as the biochemical markers of alcohol dependence. Serum nitrite concentrations were measured by Griess reaction. Results:1) The concentrations of nitrite in alcohol dependence patients were not different from those in the control subjects. 2) There were no significant association between the nitrite concentrations and the CIWA-Ar scores in alcohol dependence patients. 3) Nitrites are significantly increased in alcohol dependence group and alcohol drinking group compared with abstinence group. Conclusions:These findings suggest that serum nitrite concentration has no relation with alcohol withdrawal symptoms, but alcohol drinking increases serum nitrite concentration influenced by general condition of the body.
Alcoholism is a significant health problem in the world. The liver is the first and primary target organ for alcohol metabolism. Alcohol dehydrogenase and aldehyde dehydrogenase play important roles in the metabolism of alcohol and aldehyde. In this study, I aimed to investigate the eliminatory effects of a Phellinus spp. extract on alcohol metabolism in drunken Sprague-Dawley (SD) rats. Male SD rats were given Phellinus spp. extract at 30 min after 40% (5 g/kg) alcohol ingestion. To assay the effect of Phellinus spp. extract on blood alcohol concentration, blood samples were taken from the tail vein at 1, 3 and 5 h after alcohol ingestion. The concentrations of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase in Phellinus spp. extract treated rat were significantly lower than that of the control with a time-dependent manner. In addition, the alanine aminotransferase and aspartate aminotransferase activities of Phellinus spp. extract-treated groups were altered compared to those of the control group. These results suggest that Phellinus spp. extract intake can have a positive effect on the reduction of alcohol, alcohol dehydrogenase, and aldehyde dehydrogenase concentrations in the blood and may alleviate acute alcohol-induced hepatotoxicity by altering alcohol metabolic enzyme activities. Phellinus spp. extract is thus a good nutraceutical candidate.
The volatile flavor components in Takju made from mashed glutinous rice and barley rice were identified by GC and GC-MS using polar column. Twenty eight kinds of flavor compounds including 10 alcohols, 9 esters, 2 acids, 7 aldehydes were identified. At the beginning of fermentation 14 kinds of volatile components were detected and the kinds of volatile components were increased up to maximum after fermentation for 16 days. The contents of volatile components in the sample made from glutinous rice contained slightly higher than the sample made from barley rice. Ethyl alcohol, n-propyl alcohol, iso-amyl alcohol, n-hexyl alcohol, hexenyl alcohol, 2-phenylethyl alcohol, ethyl acetate, ethyl succinate, 2-phenylethyl acetate, butyic acid, benzaldehyde and 3-methoxybenzaldehyde were detected in the both of the sample throughout the fermentation process. Five kinds of aldehyde including ethyl propionate, iso-amyl acetate, ethyl caprylate and ethylphenyl acetate were detected only in the sample fermented for 16 days. The main components of the both sample were ethyl alcohol, iso-amyl alcohol, 2-phenylethyl alcohol, 2-phenylethyl acetate, hexenyl alcohol and iso-butyl alcohol. Besides ethyl acetate and benzaldehyde from glutinous rice Takju and hexenyl alcohol from barley rice Takju were found as main components.
