Changes in drinking status, serious illness and mortality

Prevalence and characteristics of alcohol consumption and risk of type 2 diabetes mellitus in rural China

Background

The study aimed to characterize the prevalence of alcohol consumption and further investigate the relationship between alcohol consumption and type 2 diabetes mellitus (T2DM).

Methods

We studied 39,259 participants aged 18 to 79 years of the Henan Rural Cohort study. The associations between alcohol consumption and T2DM were examined using the logistic regression models and restricted cubic spline.

Results

For men, alcohol abstinence was associated with an increased risk of T2DM (1.491(1.265, 1.758)), whereas current drinkers were not associated with T2DM (1.03(0.91, 1.15)). Further analysis of alcohol drinkers revealed that only high-risk drinkers of WHO drinking risk levels increased the risk of T2DM (1.289(1.061,1.566)) compared to never drinkers. The risk of T2DM increased as the age of starting to consume alcohol decreased and as the number of years of consuming alcohol and the alcohol intake increased only in men. We further found that the risk of T2DM decreased as the number of years of abstinence increases and no association between alcohol abstinence and T2DM was found after more than 10 years of abstinence among men.

Conclusions

Our results suggested that reducing the amount of alcohol consumed and adhering to abstinence from alcohol consumption are beneficial in reducing the risk of T2DM.

Delivery of Brief Interventions for Heavy Drinking in Primary Care: Outcomes of the ODHIN 5-Country Cluster Randomized Trial

PURPOSE

We aimed to test whether 3 strategies-training and support, financial reimbursement, and an option to direct screen-positive patients to an Internet-based method of giving brief advice-have a longer-term effect on primary care clinicians' delivery of screening and advice to heavy drinkers operationalized with the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) tool.

METHODS

We undertook a cluster randomized factorial trial with a 12-week implementation period in 120 primary health care units throughout Catalonia, England, Netherlands, Poland, and Sweden. Units were randomized to 8 groups: care as usual (control); training and support alone; financial reimbursement alone; electronic brief advice alone; paired combinations of these conditions; and all 3 combined. The primary outcome was the proportion of consulting adult patients (aged 18 years and older) receiving intervention-screening and, if screen-positive, advice-at 9 months.

RESULTS

Based on the factorial design, the ratio of the log of the proportion of patients given intervention at the 9-month follow-up was 1.39 (95% CI, 1.03-1.88) in units that received training and support as compared with units that did not. Neither financial reimbursement nor directing screen-positive patients to electronic brief advice led to a higher proportion of patients receiving intervention.

CONCLUSIONS

Training and support of primary health care units has a lasting, albeit small, impact on the proportion of adult patients given an alcohol intervention at 9 months.

Changes in heavy drinking following onset of health problems in a U.S. general population sample

Heavy episodic drinking is a well-established risk factor for heart disease, diabetes, certain cancers, stroke, hypertension and injuries, however, little is known about whether health problems precipitate changes in subsequent drinking patterns. Retrospective cohort analyses of heavy drinking by decade were conducted using data from the 2010 U.S. National Alcohol Survey (n=5240). Generalized estimating equations models were used to predict any, monthly, and weekly heavy (5+) drinking occasions across decades of life following a diagnosis of hypertension, heart problems, diabetes, stroke, cancer, or serious injury. Experiencing heart problems was associated with higher odds of reduced weekly heavy drinking (adjusted odds ratio (ORadj)=3.5; 95% confidence interval (CI); 1.7-7.4). The onset of diabetes was also associated with higher odds of reducing any heavy drinking over the decade (ORadj=1.7; 95% CI; 1.1-2.6). Cancer survivors were less likely to report no heavy drinking (ORadj=0.5; 95% CI; 0.3-0.8) or no weekly heavy drinking (ORadj=0.3; 95% CI; 0.2-0.7). Hypertension, stroke and injury were not found to have any significant associations. Reduced heavy drinking was more likely to be reported by Black drinkers following heart problems and Whites following a diabetes diagnosis. Increased heavy drinking following a cancer diagnosis was significant among women and Whites. Future studies on alcohol's heath and mortality risks should take into consideration effects of health problems on drinking patterns. Additionally, study results support increased prevention efforts targeting heavy drinking among cancer survivors, especially White women, and individuals with or being treated for hypertension.

Alcohol consumption over time and mortality in the Swedish Women's Lifestyle and Health cohort

BACKGROUND

Alcohol consumption is steadily increasing in high-income countries but the harm and possible net benefits of light-to-moderate drinking remain controversial. We prospectively investigated the association between time-varying alcohol consumption and overall and cause-specific mortality among middle-aged women.

METHODS

Among 48 249 women at baseline (33 404 at follow-up) in the prospective Swedish Women's Lifestyle and Health cohort, age 30-49 years at baseline, we used repeated information on alcohol consumption and combined this method with multiple imputation in order to maximise the number of participants and deaths included in the analyses. Multivariable Cox regression models were used to calculate HRs for overall and cause-specific mortality.

RESULTS

During >900 000 person/years, a total of 2100 deaths were recorded through Swedish registries. The median alcohol consumption increased from 2.3 g/day in 1991/1992 (baseline) to 4.7 g/day in 2004 (follow-up). Compared with light drinkers (0.1-1.5 g/day), a null association was observed for all categories of alcohol consumption with the exception of never drinkers. The HR comparing never with light drinkers was 1.46 (95% CI 1.22 to 1.74). There was a statistically significant negative trend between increasing alcohol consumption and cardiovascular and ischaemic heart diseases mortality. The results were similar when women with prevalent conditions were excluded.

CONCLUSIONS

In conclusion, in a cohort of young women, light alcohol consumption was protective for cardiovascular and ischaemic heart disease mortality but not for cancer and overall mortality.

Improving the delivery of brief interventions for heavy drinking in primary health care: outcome results of the Optimizing Delivery of Health Care Intervention (ODHIN) five-country cluster randomized factorial trial

AIM

To test if training and support, financial reimbursement and option of referring screen-positive patients to an internet-based method of giving advice (eBI) can increase primary health-care providers' delivery of Alcohol Use Disorders Identification Test (AUDIT)-C-based screening and advice to heavy drinkers.

DESIGN

Cluster randomized factorial trial with 12-week implementation and measurement period.

SETTING

Primary health-care units (PHCU) in different locations throughout Catalonia, England, the Netherlands, Poland and Sweden.

PARTICIPANTS

A total of 120 PHCU, 24 in each of Catalonia, England, the Netherlands, Poland and Sweden.

INTERVENTIONS

PHCUs were randomized to one of eight groups: care as usual, training and support (TS), financial reimbursement (FR) and eBI; paired combinations of TS, FR and eBI, and all of FR, TS and eBI.

MEASUREMENTS

The primary outcome measure was the proportion of eligible adult (age 18+ years) patients screened during a 12-week implementation period. Secondary outcome measures were proportion of screen-positive patients advised; and proportion of consulting adult patients given an intervention (screening and advice to screen-positives) during the same 12-week implementation period.

FINDINGS

During a 4-week baseline measurement period, the proportion of consulting adult patients who were screened for their alcohol consumption was 0.059 per PHCU (95% CI 0.034 to 0.084). Based on the factorial design, the ratio of the logged proportion screened during the 12-week implementation period was 1.48 (95% CI = 1.13-1.95) in PHCU that received TS versus PHCU that did not receive TS; for FR, the ratio was 2.00 (95% CI = 1.56-2.56). The option of referral to eBI did not lead to a higher proportion of patients screened. The ratio for TS plus FR was 2.34 (95% CI = 1.77-3.10), and the ratio for TS plus FR plus eBI was1.68 (95% CI = 1.11-2.53).

CONCLUSIONS

Providing primary health-care units with training, support and financial reimbursement for delivering Alcohol Use Disorders Identification Test-C-based screening and advice to heavy drinkers increases screening for alcohol consumption. Providing primary health-care units with the option of referring screen-positive patients to an internet-based method of giving advice does not appear to increase screening for alcohol consumption.

The effects of smoking and drinking on all-cause mortality in patients with dilated cardiomyopathy: a single-center cohort study

SUBJECT

Recent studies have shown that smoking and drinking are associated with poorer outcomes in patients with cardiomyopathy. The purpose of this study was to determine all-cause mortality in dilated cardiomyopathy (DCM) associated with smoking and drinking.

METHODS

An observational cohort study was undertaken in DCM patients from November 2003 to September 2011. A total of 1118 patients were enrolled, with a mean follow-up of 3.5 ± 2.3 years. Standard demographics were obtained, and transthoracic echocardiography and routine blood testing were performed shortly after admission. Outcome assessment was based on the all-cause death after admission.

RESULTS

The patients were divided into three groups: non-smokers (n = 593), mild-to-moderate smokers (n = 159) and heavy smokers (n = 366). The all-cause mortality rates showed no differences between the three groups (23.8, 20.8 and 24 %, respectively; log-rank χ (2) = 1.281, P = 0.527). There was also no significant difference in mortality between non-drinkers (n = 747), mild drinkers (n = 142) and moderate drinkers (n = 229) (23.7, 23.2 and 22.3 %, respectively; log-rank χ (2) = 2.343, P = 0.310). In the Cox analysis, neither the smoking (HR 0.971, P = 0.663) nor the drinking status (HR 0.891, P = 0.140) was a significant independent predictor of all-cause mortality in patients with DCM.

CONCLUSION

In conclusion, there were no significant differences in mortality between the smoking- and drinking-related patient groups, indicating no effect of smoking and drinking on all-cause mortality in patients with DCM in the present large-scale study.

Abstinence and current or former alcohol use as predictors of disability retirement in Finland

Aim: According to previous studies, abstinence from alcohol increases the risk of disability retirement (DR). We studied whether former alcohol users’ poor mental or physical health might have contributed to this result. Methods: Prospective population-based study of 3621 occupationally active Finns aged 30–55 years at baseline. Disability pension data for 2000−2011 was retrieved from national pension records. We examined medically certified disability retirement due to all causes and due to mental disorders among lifelong abstainers, former drinkers, those with an alcohol use disorder irrespective of consumption and current users, further classified according to weekly intake of alcohol. Chronic somatic diseases were evaluated in a clinical examination and common mental and alcohol use disorders using the Composite International Diagnostic Interview. Cox regression was used. Results: Neither lifelong abstinence nor alcohol consumption, even at hazardous levels, without alcohol use disorder was associated with disability retirement. Compared with light drinkers, former drinkers’ hazard ratio for DR due to mental disorders was 2.67 (95% CI 1.39−5.13), allowing for somatic and mental morbidity, physical and psychosocial workload, health behaviour and socio-demographic factors. The respective hazard ratio of DR due to all causes for those with alcohol use disorder was 2.17 (1.49−3.16) and of DR due to mental disorders 4.04 (2.02 to 8.06). Conclusions: Lifelong abstinence did not predict disability retirement. Former drinkers and people with alcohol use disorders were at a multi-fold risk of work disability due to mental disorders compared with light drinkers, thus it is important to support their work ability.

Alcohol consumption over time and risk of death: a systematic review and meta-analysis

The results from the few cohort studies that have measured usual alcohol consumption over time have not been summarized. We therefore conducted a systematic review and meta-analysis to quantify mortality risk. Pertinent studies were identified by searching the Medline, Web of Science, Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus, and Scopus databases through August 2012 using broad search criteria. Studies reporting relative mortality risks for quantitatively defined categories of alcohol consumption over time were eligible. Nine cohort studies published during 1991-2010 (comprising 62,950 participants and 10,490 deaths) met the inclusion criteria. For men, there was weak evidence of lower mortality risk with low levels of alcohol intake over time but higher mortality risk for those with intakes over 40 g/day compared with abstainers using a random-effects model (P for nonlinearity = 0.02). The pooled relative risks were 0.90 (95% confidence interval: 0.81, 0.99) for 1-29 g/day, 1.19 (95% confidence interval: 0.89, 1.58) for 30-59 g/day, and 1.52 (95% confidence interval: 0.78, 2.98) for 60 or more g/day compared with abstention. There was moderate between-study heterogeneity but no evidence of publication bias. Studies including women were extremely scarce. Our findings include a curvilinear association between drinking over time and mortality risk for men overall and widespread disparity in methods used to capture exposure and report results.

Prospective correlates of drinking cessation: variation across the life-course

AIMS

To assess age variation in correlates of drinking cessation.

DESIGN

Prospective study of a US general population sample.

SETTING

Face-to-face household interviews.

PARTICIPANTS

Past-year ≥ monthly drinkers interviewed at baseline and 3-year follow-up (n = 14 885).

MEASUREMENTS

Baseline values and selected changes over follow-up in alcohol consumption, alcohol use disorder (AUD), socio-demographic and health characteristics, other substance use and psychiatric comorbidity were used to predict drinking cessation in three age groups.

FINDINGS

Correlates of drinking cessation varied over the life-course, with pregnancy/presence of an infant, nicotine or drug use disorder, incident AUD, cluster A personality disorder, liver disease and incident retirement being important at younger ages and high-school graduation, family income ≥ $70 000, volume of ethanol intake, Asian race/ethnicity, mood disorder and incident cardiovascular disease being significant at older ages. Age-invariant correlates included smoking cessation over follow-up, odds ratio (OR) = 2.82 [95% confidence interval (CI): 1.62-4.92] to 3.45 (2.20-5.39); college education, OR = 0.42 (0.27-0.65) to 0.54 (0.36-0.83); black and Hispanic race/ethnicity, OR = 1.74 (1.18-2.29) to 1.88 (1.21-2.93) and 1.58 (1.11-1.25) to 1.73 (0.83-3.63), respectively, and months since last drink, OR = 1.24 (1.13-1.36) to 1.29 (1.19-1.39).

CONCLUSIONS

Factors associated with ceasing alcohol use in US adults appear to differ over the life-course, reflecting age variation in both their prevalence and impact and supporting the importance of role transitions and health problems (the 'sick quitter' effect). The most consistent correlates of drinking cessation included factors reflecting ability/inability to give up potentially addictive substances and factors associated with perceived acceptability of drinking and subgroup-specific drinking contexts that might facilitate/impede continued drinking.

Drinking patterns and the development of functional limitations in older adults: longitudinal analyses of the health and retirement survey

OBJECTIVE

To examine whether consistent low-risk drinking is associated with lower risk of developing functional limitations among older adults.

METHOD

Data were obtained from five waves of the Health and Retirement Study. Function was assessed by questions measuring four physical abilities and five instrumental activities of daily living. Five different drinking patterns were determined using data over two consecutive survey periods.

RESULTS

Over the follow-up periods, 38.6% of older adults developed functional limitations. Consistent low-risk drinkers had lower odds of developing functional limitations compared with consistent abstainers, and the effect of consistent low-risk drinking was greater among those aged 50 to 64 years compared with those aged ≥65 years. Other drinking patterns were not associated with lower odds of incident functional limitation.

DISCUSSION

Consistent low-risk drinking was associated with lower odds of developing functional limitations, and this association was greater among older middle-aged adults aged 50 to 64 years.

Coffee, tea, and alcohol intake in relation to risk of type 2 diabetes in African American women

BACKGROUND

Numerous studies have reported inverse associations of coffee, tea, and alcohol intake with risk of type 2 diabetes, but none has reported results separately among African American women.

OBJECTIVE

We prospectively examined the relation of coffee, tea, and alcohol consumption to diabetes risk in African American women.

DESIGN

The study included 46,906 Black Women's Health Study participants aged 30-69 y at baseline in 1995. Dietary intake was assessed in 1995 and 2001 by using a validated food-frequency questionnaire. During 12 y of follow-up, there were 3671 incident cases of type 2 diabetes. Relative risks (RRs) and 95% CIs were estimated by using Cox proportional hazards models adjusted for diabetes risk factors.

RESULTS

Multivariable RRs for intakes of 0-1, 1, 2-3, and ≥4 cups of caffeinated coffee/d relative to no coffee intake were 0.94 (95% CI: 0.86, 1.04), 0.90 (95% CI: 0.81, 1.01), 0.82 (95% CI: 0.72, 0.93), and 0.83 (95% CI: 0.69, 1.01), respectively (P for trend = 0.003). Multivariable RRs for intakes of 1-3, 4-6, 7-13, and ≥14 alcoholic drinks/wk relative to never consumption were 0.90 (95% CI: 0.82, 1.00), 0.68 (95% CI: 0.57, 0.81), 0.78 (95% CI: 0.63, 0.96), and 0.72 (95% CI: 0.53, 0.98), respectively (P for trend < 0.0001). Intakes of decaffeinated coffee and tea were not associated with risk of diabetes.

CONCLUSION

Our results suggest that African American women who drink moderate amounts of caffeinated coffee or alcohol have a reduced risk of type 2 diabetes.

Age-related changes in drinking patterns from mid- to older age: results from the Wisconsin longitudinal study

BACKGROUND

Drinking has generally been shown to decline with age in older adults. However, results vary depending on the measure of alcohol consumption used and the study population. The goals of this study were to (i) describe changes in drinking in a current cohort of older adults using a variety of measures of drinking and (ii) examine a number of different possible predictors of change.

METHODS

This is a longitudinal study of a community-based sample surveyed at 2 time points, ages 53 and 64 years. We estimated a series of logistic regressions to predict change and stability in drinking categories of nondrinking, moderate drinking, and heavy drinking. Linear regressions were used to predict change in past-month drinking days, past-month average drinks per drinking day, and past-month total drinks.

RESULTS

From age 53 to 64, average drinks per drinking day and heavy drinking decreased. Frequency of drinking increased for men and women, and total drinks per month increased for men. The most consistent predictors of drinking changes were gender, health, and education. Other factors predicted drinking change but were not consistent across drinking measures including: adolescent IQ, income, lifetime history of alcohol-related problems, religious service attendance, depression, debt, and changes in employment.

CONCLUSIONS

Heavy drinking decreases with age, but we may see more frequent moderate drinking with current and upcoming cohorts of older adults. Components of quantity and frequency of drinking change differently. Composite measures of total alcohol consumption may not be adequate for describing relevant changes in drinking over time. A number of factors predicted patterns of change in drinking and warrant further exploration.

How does variability in alcohol consumption over time affect the relationship with mortality and coronary heart disease?

OBJECTIVE

To examine the relationship between alcohol consumption and risk of mortality and incident coronary heart disease (CHD), taking account of variation in intake during follow-up.

METHOD

Prospective cohort study of 5411 male civil servants aged 35-55 years at entry to the Whitehall II study in 1985-88. Alcohol consumption was reported five times over a 15-year period. Mortality, fatal CHD, clinically verified incident non-fatal myocardial infarction and definite angina were ascertained during follow-up.

RESULTS

We found evidence that drinkers who vary their intake during follow-up, regardless of average level, have increased risk of total mortality (hazard ratio of high versus low variability 1.52: 95% CI: 1.07-2.17), but not of incident CHD. Using average consumption level, as opposed to only a baseline measure, gave slightly higher risk estimates for CHD compared to moderate drinkers at the extremes of the drinking range.

CONCLUSIONS

Multiple repeated measures are required to explore the effects of variation in exposure over time. Caution is needed when interpreting risks of exposures measured only once at baseline, without consideration of changes over time.

Gender and alcohol consumption: patterns from the multinational GENACIS project

AIMS

To evaluate multinational patterns of gender- and age-specific alcohol consumption.

DESIGN AND PARTICIPANTS

Large general-population surveys of men's and women's drinking behavior (n's > 900) in 35 countries in 1997-2007 used a standardized questionnaire (25 countries) or measures comparable to those in the standardized questionnaire.

MEASUREMENTS

Data from men and women in three age groups (18-34, 35-49, 50-65) showed the prevalence of drinkers, former drinkers, and lifetime abstainers; and the prevalence of high-frequency, high-volume, and heavy episodic drinking among current drinkers. Analyses examined gender ratios for prevalence rates and the direction of changes in prevalence rates across age groups.

FINDINGS

Drinking per se and high-volume drinking were consistently more prevalent among men than among women, but lifetime abstention from alcohol was consistently more prevalent among women. Among respondents who had ever been drinkers, women in all age groups were consistently more likely to have stopped drinking than men were. Among drinkers, the prevalence of high-frequency drinking was consistently greatest in the oldest age group, particularly among men. Unexpectedly, the prevalence of drinking per se did not decline consistently with increasing age, and declines in high-volume and heavy episodic drinking with increasing age were more typical in Europe and English-speaking countries.

CONCLUSIONS

As expected, men still exceed women in drinking and high-volume drinking, although gender ratios vary. Better explanations are needed for why more women than men quit drinking, and why aging does not consistently reduce drinking and heavy drinking outside Europe and English-speaking countries.

Alcohol consumption and health status in older adults: a longitudinal analysis

Objective. This longitudinal study examines the relationship of alcohol consumption to mortality and changes in mental and functional health in older adults. Method.In a national population health survey, 4,187 participants aged 50 and older at baseline provided information on alcohol consumption, potential confounders, and follow-up vital status. Logistic regression estimated the odds ratio for mortality, increase in psychological distress, and decline in functional health 10 years later. Results. Compared with lifelong abstainers, light and moderate drinkers were at nonsignificantly lower risk of mortality. Among survivors, alcohol consumption showed no consistent relationship with increases in psychological distress. Occasional and light drinkers had significantly reduced risk of a substantial functional health decline, whereas moderate drinkers had nonsignificantly reduced risk. Discussion. Findings suggest that light-to-moderate alcohol consumption reduces the risk of substantial functional health decline in older middle-aged drinkers.

Alcohol consumption of Australian women: results from the Australian Longitudinal Study on Women's Health

INTRODUCTION AND AIMS

Alcohol misuse is responsible for extensive personal harm and high societal costs. Research related specifically to women's alcohol consumption is important due to gender differences in clinical outcomes and disease progression.

DESIGN AND METHODS

This study examines longitudinal changes in the patterns of alcohol consumption associated with harm in the long term (chronic) and short term (acute) as defined by the Australian National Health and Medical Research Council. Results are presented for three age cohorts (18 - 23 years, 45 - 50 years and 70 - 75 years) using data from the Australian Longitudinal Study on Women's Health 1996 - 2003. Initial response rates for the study were 41%, 54% and 36% for the Younger, Mid-aged and Older cohort, respectively.

RESULTS

The percentages of women that initiated usual weekly consumption in excess of 140 g of alcohol, designated as long-term risky or high risk consumption, between surveys 1 and 2 were 2.7%, 2.1% and 1.7% (Younger, Mid-aged and Older cohorts, respectively). Similarly, between surveys 1 and 2, 7.8% of younger women and 2.5% of mid-aged women initiated consumption of 50 g of alcohol on one occasion at least weekly, placing them at risk of alcohol-related harm in the short-term weekly. Examining data across the three time-points in the Younger cohort, 0.3% of women were at risk of alcohol-related harm in the long term across all three time-points, and 9.2% were at risk at one or two time-points. The percentage of younger women at risk of alcohol-related harm in the short term at least weekly was 3.4% at risk at all three time-points and 24% at risk at one or two time-points.

DISCUSSION AND CONCLUSIONS

This study indicates that there is a small percentage of women who maintain levels of alcohol consumption associated with increased risk of morbidity and mortality over time, but a much larger proportion of women that drink at hazardous levels sporadically during the life course. Prevention efforts may need to target transient high-risk alcohol consumers differently than consistently heavy alcohol consumers. Non-response bias and attrition may have caused the prevalence of both entrenched and episodic heavy consumption to be underestimated.

Regular alcohol consumption is associated with increasing quality of life and mood in older men and women: the Rancho Bernardo Study

OBJECTIVE

This study examines the sex-specific association between alcohol intake and health-related quality of life in middle class community-dwelling older adults.

METHODS

Information on alcohol intake and measures of quality of life were obtained from 1594 participants (n=633 men, n=961 women) aged 50-97 years during a research clinic visit in 1992-1996, and from their responses to a phone interview and mailed questionnaires. Quality of life measures included the Medical Outcome Study Short Form 36 (SF-36), Quality of Well-Being (QWB) Scale, Life Satisfaction Index-Z (LSI-Z), and Satisfaction with Life Survey (SWLS). Depressed mood was assessed using the Beck Depression Inventory (BDI). Men and women were stratified into four groups of reported alcohol intake: non-drinker, occasional drinker (alcohol <3 times/week), light regular drinker (alcohol intake >/=3 times/week, but <170g/week), and moderate regular drinker (alcohol intake >/=3 times/week and >/=170g/week).

RESULTS

Average age of both sexes was 72+/-10 years. Only 11% of the men and 17% of the women were non-drinkers; 54% of men and 40% of women reported drinking alcohol >/=3 times per week; 18% of men and 7.5% of women were heavier regular drinkers. In multivariable regression analyses, increasing frequency of alcohol use was positively associated with better quality of life in men and in women. Associations were not explained by age, physical activity, smoking, depressed mood, or common chronic diseases including diabetes, hypertension and cardiovascular disease.

CONCLUSIONS

Regular alcohol consumption is associated with increased quality of life in older men and women.

Stability and change in health-related behaviors of midlife Swedish women

We investigated the dimensions and stability in health-related behaviors (HRBs) among midlife Swedish women, and the factors that predicted change in those behaviors. At age 43, 569 women from a representative longitudinal sample completed questionnaires about lifestyle (diet, exercise, smoking, alcohol) and participated in medical screening. Four years later we mailed a follow-up questionnaire. HRBs clustered in two dimensions: healthy eating and addictions. There was a high degree of stability in HRBs; all women slightly increased their HRBs over time. After controlling for previous HRBs, we found that education, marital status, and having children at home were significant predictors of HRBs 4 years later.

Are lifetime abstainers the best control group in alcohol epidemiology? On the stability and validity of reported lifetime abstention

Lifetime abstainers have often been recommended as the comparison group in alcohol epidemiology. The objective of this study was to provide insight into the validity and stability of lifetime abstention by using data derived from the National Alcohol Survey, a national probability survey of US households conducted in 1984, and its 2 follow-up surveys conducted in 1990 and 1992. Results indicated that more than half (52.9%; all proportions were weighted to represent the US population) of those who reported never having a drink of any alcoholic beverage in the 1992 survey reported drinking in previous surveys. Depending on assumptions, this difference may result in an underestimation of alcohol-attributable mortality of 2%-15% in men and 2%-22% in women. Sociodemographic factors differentiated those who consistently reported lifetime abstention across surveys from the rest of the study population. Results suggest that using reported lifetime abstainers as a sole comparison group is problematic, especially if reporting is based on 1 measurement only. Establishing multiple measurement points and including irregular lifetime light drinkers with lifetime abstainers as the comparison group are recommended for future epidemiologic studies.

Longitudinal analysis of alcohol consumption and health of middle-aged women in Australia

AIMS

To assess the prospective association between alcohol consumption and self-rated health: in particular whether there is a relationship between stable alcohol intake and health; whether health is affected by changes in alcohol consumption; whether having a chronic condition alters the relationships between stable and changing alcohol intake and health; and whether the health of longer-term abstainers is different from more recent and intermittent abstainers.

DESIGN

Longitudinal analysis of a prospective, population-based study.

SETTING

Australia.

PARTICIPANTS

A total of 13 585 randomly selected 45-50-year-old women surveyed in 1996, of whom 9396 (69%) were resurveyed in 1998, 2001 and 2004.

MEASUREMENTS

Estimates for the General Health subscale of the SF-36 for different levels of alcohol intake adjusted for having a chronic condition, depression, smoking and other factors.

FINDINGS

Longitudinal models of consistent alcohol intake showed mean scores for general health of moderate drinkers were significantly better than that of non-drinkers [mean difference = 4.3, standard error (SE) = 0.61], occasional drinkers (mean difference = 3.1, SE = 0.52) and heavy drinkers (mean difference = 2.1, SE = 1.00). Among moderate drinkers, a decrease or variation in alcohol consumption was associated with a significant decline of three to four points in general health. Similar results were obtained when women with an existing chronic condition were excluded from these models. The health of recent abstainers and intermittent drinkers was the same as longer-term abstainers.

CONCLUSIONS

Consistent moderate drinkers had the best health even after adjustment for having a chronic condition, depression and life-style factors. Poorer health was associated with decreased alcohol intake among occasional and moderate drinkers.

Effect of alcohol on risk of coronary heart disease and stroke: causality, bias, or a bit of both?

Epidemiological studies of middle-aged populations generally find the relationship between alcohol intake and the risk of coronary heart disease (CHD) and stroke to be either U- or J-shaped. This review describes the extent that these relationships are likely to be causal, and the extent that they may be due to specific methodological weaknesses in epidemiological studies. The consistency in the vascular benefit associated with moderate drinking (compared with non-drinking) observed across different studies, together with the existence of credible biological pathways, strongly suggests that at least some of this benefit is real. However, because of biases introduced by: choice of reference categories; reverse causality bias; variations in alcohol intake over time; and confounding, some of it is likely to be an artefact. For heavy drinking, different study biases have the potential to act in opposing directions, and as such, the true effects of heavy drinking on vascular risk are uncertain. However, because of the known harmful effects of heavy drinking on non-vascular mortality, the problem is an academic one. Studies of the effects of alcohol consumption on health outcomes should recognise the methodological biases they are likely to face, and design, analyse and interpret their studies accordingly. While regular moderate alcohol consumption during middle-age probably does reduce vascular risk, care should be taken when making general recommendations about safe levels of alcohol intake. In particular, it is likely that any promotion of alcohol for health reasons would do substantially more harm than good.

Underage alcohol use, delinquency, and criminal activity

Since 1988, the minimum legal drinking age (MLDA) has been 21 years for all 50 US states. The increasing prevalence of teenagers driving under the influence (DUI) of alcohol and the resulting traffic accidents were two main reasons for raising the MLDA to 21 years. Following the passage of this legislation, several published studies have found that the higher MLDA is associated with a significant reduction in both fatal and non-fatal accidents. While the relationship between MLDA and DUI events among young adults has been extensively studied, less information is available on other potential consequences of underage drinking. The present study uses data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a recent nationally representative survey, to investigate the effects of underage drinking on a variety of delinquency and criminal activity consequences. After controlling for the endogeneity of alcohol use where appropriate, we find strong evidence that various measures of alcohol consumption are related both to delinquency and to criminal activity. However, the findings are not uniform across gender as we find striking differences between males and females. These results have interesting policy and public health implications regarding underage drinking.

Changing drinking pattern does not influence health perception: a longitudinal study of the atherosclerosis risk in communities study

OBJECTIVE

To investigate if dynamic changes in the pattern of alcoholic beverages consumption are associated with modifications in health perception.

DESIGN, SETTING, AND PARTICIPANTS

This study investigated 12 332 middle aged men and women from the atherosclerosis risk in communities study who reported drinking status and perceived health triennially from 1987 to 1995. Crude and adjusted risks for change in health perception between visits two and three by change in drinking status between visits one and two were computed. In the multivariate analysis the sample was restricted to participants with stable drinking status between visit two and three and stable health perception between visits one and two, to assure that exposure and outcome were not temporary. Covariates included age, sex, race, income, smoking status, educational level, and obesity.

RESULTS

Health for persons who stopped or started drinking, or continued to abstain was more likely to decline than was health for persons who continued to drink even after adjustment and restrictions (drinking cessation: OR = 1.6, 95% CI = 1.1, 2.3; started drinking; OR = 1.4, 95% CI = 0.9, 2.2; continued abstaining from alcohol: OR = 1.5, 95% CI = 1.3, 1.9). Among participants with poor perceived health, starting, stopping, or continuing to abstain from alcohol did not improve health in relation to participants that continued to drink.

CONCLUSION

Increasing and decreasing drinking patterns and continuous abstinence were associated with declining health perception in comparison with continuous drinking, while starting or stopping drinking did not improve health perception of persons with poor perceived health. These findings suggest that change in health perception was not biologically related to alcohol consumption.

Predictors of 16-Year Mortality Among Individuals Initiating Help-Seeking for an Alcoholic Use Disorder

BACKGROUND AND METHODS

We examined rates and predictors of mortality in individuals (47% women) who had just initiated help-seeking for their alcohol use disorders (AUDs) at the start of the study (n=628) and were followed for 16 years.

RESULTS

For both women and men, the observed-to-expected mortality ratio (1.4) was lower than rates found in samples of treated individuals with AUDs, suggesting that those initiating help-seeking careers have better chances of long-term survival. Of the individuals for whom cause of death was known, 68% died of alcohol-related causes. Men were more likely to die than were women. When gender was controlled, individuals who were older and unmarried and had more alcohol dependence symptoms at baseline were more likely to die over the 16-year period. When these baseline characteristics were controlled, better drinking outcomes at 1 year were associated with a lower likelihood of subsequent death. The combination of a shorter duration of inpatient/residential care and better drinking outcomes at 1 year was related to a lower probability of death, as was the combination of a longer duration of outpatient care or Alcoholics Anonymous attendance and better drinking outcomes at 1 year.

CONCLUSIONS

Efforts should be made to help providers identify individuals who are not responding positively to inpatient or residential treatment and intervene to motivate participation in continuing outpatient care and community 12-step self-help groups to reduce the likelihood of a chronic and fatal AUD course.

A Drink to Healthy Aging: The Association Between Older Women's Use of Alcohol and Their Health-Related Quality of Life

OBJECTIVES

To assess the relationship between alcohol intake and mortality in a cohort of women aged 70 and older and to explore the relationship between level of alcohol use and changes in physical and mental health-related quality of life.

DESIGN

National longitudinal surveys from 1996 to 2002.

SETTING

Community based.

PARTICIPANTS

A national random sample of 12,432 Australian women aged 70 to 75 at baseline.

MEASUREMENTS

Alcohol consumption was the factor of interest, and the main outcome measures were survival and health-related quality of life, with adjustment for potential confounders.

RESULTS

Women who did not consume alcohol or who drank rarely were more likely to die (nondrinkers' hazard (HR) = ratio 1.94, 95% confidence interval (CI) = 1.4-2.6; rare drinkers' HR = 1.58, 95% CI = 1.2-2.1) than women in the low-intake reference category (1-2 drinks per day, 3-6 days per week), or if they survived, they had lower health-related quality-of-life scores on the General Health and Physical Functioning subscales of the Medical Outcomes Study 36-item Short Form Survey after adjustment for smoking, comorbidity, education, body mass index, and area of residence. Nondrinkers also scored lower on the Mental Health and Social Functioning subscales.

CONCLUSION

Being a nondrinker of alcohol was associated with greater risk of death and poorer health-related quality of life. Results for other levels of intake were consistent with current Australian alcohol consumption recommendations for women and indicated that moderate alcohol intake may carry some health benefits for older women in terms of survival and quality of life.

Longevity, big five personality factors, and health behaviors: presidents from Washington to Nixon

In this study, the positive correlation between conscientiousness and death age discovered by H. S. Friedman et al. (1993, 1995) was replicated for 32 American presidents. Conscientiousness scores, using the Big Five variables produced by S. J. Rubenzer, T. R. Faschingbauer, and D. S. Ones (1996, 2000), were correlated with death age, r(30) = .41, p < .01, and the relationship was maintained with controls in a multiple regression framework. Smoking, drinking, and exercise, as assessed by J. R. Bumgarner (1994), were also correlated in the expected fashion with death age. Conscientiousness was correlated negatively with smoking and drinking, but openness to experience was correlated negatively with smoking and drinking to a higher degree and also was positively correlated with exercise. Openness, extraversion, neuroticism, and agreeableness were not correlated with death age, and extraversion, neuroticism, and agreeableness were not correlated with smoking, drinking or exercise.

Alcohol intake in middle age and risk of cardiovascular disease and mortality: accounting for intake variation over time

Moderate alcohol consumption is associated with a decreased risk of cardiovascular disease. However, the impact of variation in alcohol intake over time on estimated risk relations has not been adequately addressed. In this study, 6,544 middle-aged British men without previous cardiovascular disease were followed for cardiovascular events and all-cause mortality over 20 years from 1978/1980 to 1998/2000. Alcohol intake was ascertained at regular points throughout the study. A total of 922 men had a major coronary event within 20 years, 352 men had a stroke, and 1,552 men died of all causes. Baseline alcohol intake displayed U-shaped relations with cardiovascular disease and all-cause mortality, with light drinkers having the lowest risks and nondrinkers and heavy drinkers having similarly high risks. However, the nature of these relations changed after adjustment for intake variation; risks associated with nondrinking were lowered, and risks associated with moderate and heavy drinking increased. Regular heavy drinkers had a 74% higher risk of a major coronary event, a 133% higher risk of stroke, and a 127% higher risk of all-cause mortality than did occasional drinkers (these estimates were 8%, 54%, and 44% before adjustment for intake variation). The findings suggest that considerable caution may be needed before any recommendations regarding acceptable limits of alcohol consumption are made.
