Heavy drinking, but not moderate or intermediate drinking, increases the risk of intracerebral hemorrhage

An increased risk of intracerebral hemorrhage among heavy consumers of alcohol has been demonstrated in several epidemiologic studies. The effect of moderate or intermediate intakes is, however, unclear. Although several studies provide evidence for a protective effect, this conclusion may be spurious, resulting from the inclusion, within the zero intake (reference) group, of past drinkers who have recently abstained for health reasons. The present study describes the relation between alcohol consumption and intracerebral hemorrhage among 331 case-control pairs recruited in Melbourne, Australia. Heavy drinking was associated with an increased risk of intracerebral hemorrhage (odds ratio (OR) 3.4, 95% confidence interval (CI) = 1.4-8.4). The odds ratio of intracerebral hemorrhage with moderate drinking, when compared with never drinkers, was 0.7, (95% CI = 0.4-1.2) and was 0.6 (95% CI = 0.4-1.0) when compared with nondrinkers (never drinkers plus past drinkers). Wine drinkers were apparently protected from intracerebral hemorrhage (OR 0.5, 95% CI = 0.2-0.9). These results are consistent with the possibility that moderate drinking may confer protection from intracerebral hemorrhage, but this protection may be less than that previously reported.     

脂蛋白(a)与年轻人脑梗死

目的 研究脂蛋白(a)与年轻人脑梗死发病的关系。方法 检测90例发病年龄16—45岁脑梗死患者脂蛋白(a)与甘油三酯、总胆固醇、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇、载脂蛋白A—I、载脂蛋白B等，同时分析患者的高血压、吸烟、饮酒、卒中家族史等因素。结果 与对照组相比，脑梗死患者的脂蛋白(a)无显著性增高。而甘油三酯、载脂蛋白B在脑梗死患者中却显著增高。相关分析显示，脂蛋白(a)与血清总胆固醇和低密度脂蛋白胆固醇正相关(P＜0．01)。logistic回归分析示高脂蛋白(a)的相对危险度比值比(OR)为0．74，95％CI：0．27一1．98。高甘油三酯对于脑梗死的OR值为3．57，95％CI：1．34—9．49；高血压对于脑梗死的OR值为8．18，95％CI：2．54—26．33；心脏病对于脑梗死的OR值为8．5l，其95％CI：2．27—31．85；吸烟的OR值为3．2l，95％CI：1．27—8．13。结论 脂蛋白(a)可能不是年轻人脑梗死的危险因素。高甘油三酯、高血压、心脏病和吸烟是年轻人脑梗死重要的危险因素。     

Risk modifying effect of social capital on measures of heavy alcohol consumption, alcohol abuse, harms, and secondhand effects: national survey findings

STUDY OBJECTIVE: To examine associations between social capital and individual risk for alcohol abuse and harms and identify protective effect mechanisms. DESIGN: Multilevel multivariate analysis with individual level data from a national panel survey of drinking and a contextual measure of social capital reflecting college mean aggregate reports of student volunteerism. Outcomes include heavy episodic (binge) drinking, frequent drinking, frequent drunkenness, diagnosable alcohol abuse, intentional drunkenness, acquisition of binge drinking, harms, secondhand effects from others' drinking. SETTING: United States, 119 four year colleges. PARTICIPANTS: Representative samples of youth ages 18-24 surveyed in 1997 and 1999 using an anonymous mailed questionnaire (total n = 27 687). MAIN RESULTS: Students from colleges with higher levels of social capital reported reduced risks for binge drinking (adjusted OR 0.38, 95% CI 0.20 to 0.69, p = 0.002), frequent drunkenness (adjusted OR 0.58, 95% CI 0.34 to 0.98, p = 0.04), acquisition of binge drinking in college (adjusted OR 0.48, 95% CI 0.24 to 0.95, p = 0.03), and alcohol abuse (adjusted OR 0.55, 95% CI 0.34 to 0.91, p = 0.02) in multilevel multivariate analyses that controlled for individual volunteering, the measure on which social capital was based. Higher levels of social capital protected against multiple drinking related harms (adjusted OR 0.51, 95% CI 0.29 to 0.90, p = 0.02) and secondhand drinking effects (adjusted OR, 0.30, 95% CI 0.16 to 0.58, p = 0.0003). Significant cross level interactions exist between fraternity/sorority membership and social capital for measures of risky drinking. Harm reduction primarily reflects consumption modification. CONCLUSIONS: Social capital exerts strong protective effects on alcohol abuse and harm in college including among high risk students.     

Absence of religious beliefs,unhealthy eating habits,illicit drug abuse,and self-rated health is associated with alcohol and tobacco use among college students — PADu study

Aim

Describing the factors associated with the alcohol consumption, tobacco use, binge drinking, and “binge drinking and tobacco use” by college students.

Subject and methods

Cross-sectional study carried out with 356 first-semester college students of a public educational institution at Minas Gerais, Brazil. Sociodemographic characteristics, lifestyle habits (alcohol consumption, tobacco and illicit drugs use, exposure time on screens, and eating habits), and health conditions (weight, height, self-rated health, symptoms of anxiety, and depression) were collected. Statistical analysis was performed using Stata® software version 13.0.

Results

The prevalence of alcohol consumption, tobacco use, binge drinking, and “binge drinking and tobacco use” were 73.9%, 17.4%, 43.5%, and 13.4%, respectively. Had no religious beliefs was associated with alcohol consumption (OR: 1.86 95% CI 1.06–3.27), tobacco use (OR: 2.00 95% CI 1.06–3.78), and “binge drinking and tobacco use” (OR: 2.33 95% CI 1.09–4.96). Unhealthy eating habits was associated with alcohol consumption (OR: 2.06 95% CI 1.06–3.97) and tobacco use (OR: 2.74 95% CI 1.33–5.68; OR: 0.75 95% CI 0.31–1.80). Illicit drugs was associated with alcohol consumption (OR: 8.55 95% CI 1.12–65.42) and tobacco use (OR: 3.19 95% CI 1.20–8.51). Self-rated health was associated with tobacco use, combined (OR: 2.93 95% CI 1.37–6.28) or not (OR: 2.46 95% CI 1.32–4.61) with binge drinking. Additionally, tobacco use was associated with white skin color (OR: 2.62 95% CI 1.35–5.07) and being homosexual (OR: 0.37 95% CI 0.18–0.75). Moreover, “binge drinking” was associated with being overweight (OR: 1.72 95% CI 1.03–2.84). Associations remained in the age and sex adjustment.

Conclusion

It was observed that some factors associated with alcohol consumption and tobacco use are modifiable risk factors. Therefore, we suggest strategic actions focusing on raising the population’s awareness to change these factors. Longitudinal studies are necessary to understand the causal relationship between studied variables and, thus, develop strategic actions to improve the life quality of this population group.

A case-control study of maternal alcohol consumption and intrauterine growth retardation

PURPOSE: Heavy maternal drinking during pregnancy causes fetal alcohol syndrome, but whether more moderate alcohol consumption is associated with such adverse pregnancy outcomes as intrauterine growth retardation (IUGR) remains controversial. METHODS: Using data from a case-control study, we examined the association between maternal alcohol consumption and risk for IUGR among 701 case and 336 control infants born during 1993-1995 in Monroe County, New York. RESULTS: Our results provide no evidence of an independent association between moderate maternal alcohol consumption (<14 drinks per week) and risk for IUGR. The risk for IUGR among heavy drinkers (> or =14 drinks per week) around the time of conception was OR = 1.4 (95% CI 0.7-2.6) for IUGR < or = 5th percentile and OR = 1.4 (95% CI 0.7-2.8) for IUGR 5th-10th percentile. For heavy drinkers during the first trimester, the OR was 1.3 (95% CI 0.4-4.5) for IUGR < or = 5th percentile and OR = 1.3 (95% CI 0.4-4.8) for IUGR 5th-10th percentile. CONCLUSIONS: Since IUGR is a heterogeneous outcome with a possible multifactorial origin, further studies are needed to examine the combined effects of alcohol and other environmental and genetic factors on IUGR risk for subgroups of IUGR.     

Alcohol intake, drinking patterns, and risk of nonfatal acute myocardial infarction in Costa Rica

BACKGROUND: Moderate alcohol consumption is associated with a lower risk of myocardial infarction (MI). Whether alcohol is truly protective or whether the amount, type, or pattern of intake is the most important is still under debate. OBJECTIVE: The purpose of this study was to determine whether alcohol intake and drinking patterns are associated with plasma lipids and the risk of MI in Costa Ricans, a population with a low intake of wine. DESIGN: We conducted a study of 2090 cases of a first nonfatal acute MI and 2090 population-based controls matched by age, sex, and residence in Costa Rica, a country with diet and lifestyles different from those of Western countries. Alcohol and dietary intakes were assessed by using validated questionnaires. RESULTS: In a multivariate conditional regression model that controlled for other cardiovascular disease risk factors, the lowest risk of MI [odds ratio (OR) = 0.44; 95% CI: 0.31, 0.61] was observed for those who drank on average 3 drinks/wk (compared with lifelong abstainers). When we looked at the frequency of consumption, we found that the risk of MI among daily drinkers (OR = 0.64; 95% CI: 0.41, 1.01) was not significantly different (P = 0.23) from that of weekend drinkers (OR = 0.76; 95% CI: 0.59, 0.98) regardless of the amount consumed. HDL cholesterol increased with the amount and frequency of alcohol intake. Similar to a few other populations, apparent protection was observed at very low alcohol intakes. CONCLUSION: Low to moderate consumption of alcohol 1-2 d/wk is independently associated with a reduced risk of MI.     

沈阳农村60岁以上人群良性前列腺增生危险因素的病例对照研究

目的：探讨各种危险因素与良性前列腺增生（BPH）的关系。方法：采用以人群为基础的病例对照研究，病例组为沈阳市某郊区农村60周岁以上BPH患者，对照组为无前列腺增生（排除前列腺癌、前我腺炎等疾病）的老年男性，病例与对照各100例，单因素分析采用χ^2检验，多因素分析利用非条件logistic回归分析。结果：多因素非条件logistic回归分析显示BPH发病与下列5种因素有关：患前列腺炎（OR＝5．577，95％CI：2．147－14．482）；20世纪80年代初每月肉类摄入量（OR＝4．930，95％CI：2．404－10．111）；舒张压（OR＝1．050，95％CI：0．480－0．881）。结论：患前列腺炎、80年代初每月过多摄入肉类、舒张压高可能是BPH的危险因素；吸烟量大、饮酒量大可能是BPH保护因素。     

Alcohol intake and the pattern of trauma in young adults and working aged people admitted after trauma

AIMS: To investigate the relationship of different patterns of alcohol intake to various types of trauma. METHODS: We examined the associations of alcohol consumption in a series of 385 consecutive trauma admissions (278 men, 107 women, age range 16-49 years). Patients underwent clinical examinations, structured interviews on the amount and pattern of alcohol intake, and measurements of blood alcohol concentration (BAC). RESULTS: On admission, 51% of the patients had alcohol in their blood. Binge drinking was the predominant (78%) drinking pattern of alcohol intake. Assaults, falls and biking accidents were the most frequent causes of trauma. Dependent alcohol drinking and binge drinking were found to be significantly more common among patients with head trauma than in those with other types of trauma (77% vs 59%, OR=2.38; 95% CI 1.50 to 3.77). The OR for sustaining head injury increased sharply with increasing BAC: 1-99 mg/dl (1.24; 95% CI 0.55-2.01), 100-149 mg/dl 1.64; 95% CI 0.71-3.77), 150-199 mg/dl (3.20; 95% CI 1.57-6.53) and >199 mg/dl (9.23; 95% CI 4.79-17.79). CONCLUSIONS: Binge drinking is a major risk factor for head trauma among trauma patients. Assaults, falls and biking accidents are the commonest causes for such injuries. The relative risk for head injury markedly increases with increasing blood alcohol levels. Alcohol control measures should feature in policies aiming at the prevention of trauma-related morbidity and mortality.     

Poor health is associated with episodic heavy alcohol use: evidence from a National Survey

OBJECTIVES: The objective of this study was to examine the relationship between self-rated health and episodic heavy drinking in a representative sample of American adults. We also sought to determine ethnic and gender differences in the association between self-rated health and episodic heavy drinking. METHODS: Data (n=4649) from the Third US National Health and Nutrition Examination Survey were utilized for this investigation. Episodic heavy drinking was defined as the consumption of five or more and four or more alcoholic beverages on one occasion for men and women, respectively. Poor health was defined as answering fair or poor to the question: "Would you say your health in general is excellent, very good, good, fair or poor?" Odds ratio from the logistic linear regression analysis was used to estimate the risk for poor health that was associated with episodic heavy drinking. Statistical adjustments were made for age, hypertension, diabetes, current smoking, body mass index and race/ethnicity. RESULTS: Overall, episodic heavy drinking was associated with increased odds of poor self-rated health in men and women. In men, episodic heavy drinking was independently associated with 1.28 (95% CI: 1.07-1.82) increased odds of poor health. The corresponding value in women was 1.86 (95% CI: 1.05-2.28). In men, being Black was associated with approximately two-fold (OR=1.96; 95% CI: 1.33, 2.89), and being Hispanic was associated with approximately four-fold (OR=3.59; 95% CI: 2.50, 5.14) increased odds of poor self-rated health relative to being White. The corresponding odds ratios in women were 2.97 (95% CI: 1.90, 4.64) and 5.18 (95% CI: 3.23, 8.30). Associations were greater among blacks (adjusted OR=2.41; 95% CI: 1.81-3.22) and Hispanics (adjusted OR=4.15; 95% CI: 3.12-5.52) than among whites. CONCLUSIONS: Poor health is associated with episodic heavy alcohol consumption. Public health strategies to curb alcohol abuse may improve self-reported health status in these at-risk populations.

Apolipoprotein E genetic polymorphism and stroke subtypes in a Bangladeshi hospital-based study.

The association between apolipoprotein E (apoE) genetic polymorphism and stroke has not been concordant in different racial populations. We investigated the association between apoE genotypes and stroke subtypes by a case-control study in Bangladesh for the first time among south Asian countries. First-ever-stroke patients (n=227; cerebral infarction, n=147, cerebral hemorrhage, n=80) and 190 controls were recruited from a hospital in Dhaka, Bangladesh. The diagnosis of stroke was based on CT and clinical findings. Cerebral infarction was classified anatomically into cortical and penetrating region. Infarction in the cortical region was further categorized etiologically into thrombosis and embolism. Cerebral hemorrhage was considered as a whole in all analyses. ApoE genotypes were determined by restriction fragment length polymorphism. In the multivariate conditional logistic regression analysis adjusted for potential confounders both the epsilon3/epsilon4 genotype and epsilon4 carrier conferred an approximately 3-fold increased risk for cerebral thrombosis in the cortical artery region (OR 3.5, 95% CI 1.2 to 10.4 and OR 3.1, 95% Cl 1.1 to 9.0, respectively) compared with epsilon3/epsilon3 genotype. However, when the analysis was restricted to the elderly (>60 years), epsilon 2 carrier was associated with a risk of hemorrhagic stroke (OR 19.2, 95% CI 1.3 to 295.2). Our study suggested that both apoE epsilon3/epsilon4 genotype and epsilon4 carriers were risk factors for cerebral thrombosis in cortical artery region, whereas epsilon 2 carrier was a risk factor for hemorrhagic stroke in the elderly.     

Analysis of factors related to smoking initiation and continued smoking in young adolescents

OBJECTIVE: To analyse the determining of the acquisition and later consolidation of the tobacco consumption in young adolescents. MATERIAL AND METHOD: Longitudinal study of three years of duration (2000-2002). Subjects were students of secondary education between 13 and 14 years old at the beginning of the study. The research was performed in Gran Canaria Island with a final sample of 745 subjects. Models of conditional binary election were considered for longitudinal data where the dependent variable reflects decisions of the adolescents through time, with regard to the probability of beginning to smoke, "beginning model", and the probability of being occasional or habitual smoker, "experimentation model". RESULTS: In the last year, 57% of the young teenagers surveyed use tobacco, a 25% more than in the first year, some of them, 9% on a daily basis. In the "beginning model" the determining of the tobacco consumption are interest in studies (odds ratio [OR] = 0.27; 95% confidence interval (CI), 0.08-0.87 and OR = 0.14; 95% CI, 0.03-0.58 for the students having enough and much interest in studies, respectively), to have a smoker as the best friend (OR = 7.44; 95% CI, 2.59-21.4), the alcohol consumption (OR = 11.82; 95% CI, 4.96-28.2 and OR=15.42; 95% CI, 4.68-50.7 for youngs who drink alcohol occasionally or frequently) and having more pocket money (euros per week) (OR = 1.13; 95% CI, 1.07-1.19). For the "experimentation model", to have a smoker as the best friend (OR = 7.01; 95% CI, 2.96-16.5), the alcohol consumption (OR = 5.71; 95% CI, 1.98-16.4 and OR = 5.22; 95% CI, the 1.56-17.5 for youngs who drink alcohol occasionally or frequently) and the number of years since the student started smoking (OR = 1.44; 95% IC, 1.11-1.86). CONCLUSIONS: Our study emphasizes, peer group effect, drinking alcoholic beverages and lack of interest in studies as factors associated to the tobacco consumption.

国内吸烟、饮酒与缺血性脑卒中关系的Meta分析

目的探讨吸烟、饮酒与缺血性脑卒中的关系.方法应用Meta分析方法对检索到的国内10个吸烟、饮酒与缺血性脑卒中关系的研究结果进行定量综合分析,一致性检验后,应用随机效应模型(D-L法)计算,合并比值比(OR)及其95%的可信区间(95% CI).结果吸烟、饮酒的合并OR(95% CI)分别为2.01(1.41～2.85)和2.36(1.87～2.98).吸烟、饮酒高危人群缺血性脑卒中的病因分值为50.25%和57.63%,一般人群归因危险百分比为26.66%和34.83%.结论吸烟、饮酒是我国缺血性脑卒中的重要危险因素,开展人群戒烟限酒干预是缺血性脑卒中病因预防的一项重要措施.     

Sex-related alcohol expectancies and high-risk sexual behaviour among drinking adults in Kampala,Uganda

Alcohol consumption, a risk factor for HIV transmission in sub-Saharan Africa, is considered high in Uganda. A cross sectional study was conducted to determine whether sex-related expectations about the effects of alcohol explain the association between alcohol use and risky sexual behaviours in a population-based sample of adults in Kampala. Associations between alcohol use (current and higher risk drinking) and high-risk sexual behaviours (multiple regular partners and casual sex) were tested. In age–sex-adjusted models, having multiple regular partners was associated with current drinking (odds ratio [OR] = 2.76, 95% confidence intervals [CIs] = 1.15, 6.63) and higher risk drinking (OR = 3.35, 95% CI = 1.28, 8.71). Associations were similar but not statistically significant for having a causal sex partner. Sex-related alcohol outcome expectancy was associated with both alcohol use and high-risk sexual behaviour and attenuated relationships between multiple regular partners and both current drinking (OR = 1.94, 95% CI = 0.57, 6.73) and higher risk drinking (OR = 2.44, 95% CI = 0.68, 8.80). In this setting sexual behaviours related with alcohol consumption were explained, in part, by sex-related expectations about the effects of alcohol. These expectations could be an important component to target in HIV education campaigns.

Patterns of alcohol consumption among pregnant African-American women in Washington, DC, USA

The objective of this paper is to describe the patterns and associated behaviours related to alcohol consumption among a selected sample of pregnant women seeking prenatal care in inner city Washington DC. Women receiving prenatal care at one of nine sites completed an anonymous alcohol-screening questionnaire. Questions concerned the amount, type and pattern of alcohol consumption. Women were categorised as at no, low, moderate or high risk for alcohol consumption during pregnancy. For comparisons of risk levels of drinking, bivariate associations were examined using Fisher's exact test. Odds ratios (ORs) and 95% confidence intervals (CIs) were also computed. Although 31% of current/recent drinkers stated that they continued to drink during pregnancy, responses to quantity/frequency questions revealed that 42% continued to do so. Women who were at high compared with moderate risk acknowledged that others were worried about their consumption [OR=4.0, 95% CI 1.5, 10.6], that they drank upon rising [OR=6.7, 95% CI 1.8, 26.9], had a need to reduce drinking [OR=3.2, 95% CI 1.3, 8.1] and in the past 5 years had had fractures [OR=4.2, 95% CI 1.0, 17.8] or a road traffic injury [OR=3.4, 95% CI 1.0, 12.2]. Women in the high/moderate compared with low-risk group were more likely to have been injured in a fight or assault [OR=2.7, 95% CI 1.3, 5.6]. This study validated the usefulness of our questionnaire in identifying women who were at risk for alcohol consumption during pregnancy across a range of consumption levels. Using our screening tool, women were willing to disclose their drinking habits. This low-cost method identifies women appropriate for targeting of interventions.

目的 研究亚甲基四氢叶酸还原酶(MTHFR)基因1298A→C多态及其和生活习惯相互作用与食管癌易感性的关系。方法 在食管癌高发区的淮安市楚州区开展了一项病例对照研究(食管癌患者141例,人群对照228名),调查研究对象的生活习惯,采用聚合酶链反应-限制性片段长度多态性技术检测研究对象的MTHFR 1298A→C基因型。结果 ①食管癌组中MTHFR 1298 AA、AC和CC基因型携带者的比例分别为63.8％、34.0％和2.1％,与对照组的71.9％、28.1％和0.0％相比,差异有统计学意义(X_(MH)~2=6.69,P=0.035)。②在MTHFR 1298C等位基因携带者中,伴有吸烟习惯者发生食管癌的调整OR为3.48(95％CI:1.57～7.71),伴有经常饮酒的习惯者发生食管癌的调整OR为2.91(95％CI:1.20～7.08),无饮茶习惯者发生食管癌的调整OR为3.52(95％CI:1.64～7.54)。MTHFR 1298AC和CC基因型与吸烟、饮酒和不饮茶在食管癌发生中的相互作用系数r分别为3.05、3.69和6.30。结论 MTHFR 1298AC和CC基因型对吸烟、饮酒和不饮茶增加食管癌发生风险的作用有明显的放大效应。     

Do Tobacco and Alcohol Modify Protective Effects of Diet on Oral Carcinogenesis?

Recent systematic reviews concluded that the frequent consumption of fruits and vegetables is inversely associated with the risk of oral cancer. We assessed this association, specifically comparing results obtained to nonsmokers and smokers, as well to nondrinkers and drinkers. We conducted a case-control study involving 296 patients with oral squamous cell carcinoma (cases) attended in 3 major hospitals of São Paulo, Brazil, paired with 296 controls, recruited from outpatient units of the same hospitals. Multivariate models assessed the effect of fruits and salads according to smoking and drinking. The intake of fruit was associated with the prevention of the disease in the specific assessment among light [odds ratio (OR) = 0.46; 95% confidence interval (CI) = 0.27–0.78) and heavy (OR = 0.30; 95% CI = 0.14–0.65) smokers. The same was observed for vegetables consumption. For nonsmokers, no fruit (OR = 50; 95% CI = 0.22–1.12) or vegetable (for tomato, OR = 0.53; 95% CI = 0.31–0.93) was associated with reduced risk of oral and oropharyngeal cancer. Similar results were found in the stratified analysis according to drinking status with OR = 0.51 (95% CI = 0.30–0.87) and 0.18 for fruits (95% CI = 0.07–0.45), respectively, for light and heavy drinkers. This observation suggests that the protective effect of fruit and salad intake may modulate the deleterious effects from tobacco and alcohol.
