Longitudinal patterns and predictors of alcohol consumption in the United States

Drinking behavior among older adults at a continuing care retirement community: affective and motivational influences

OBJECTIVES

The purpose of this pilot study was to describe patterns of alcohol consumption among continuing care retirement community(CCRC) residents and to explore the role of drinking motives and affective states on drinking context and consumption.

METHOD

We utilized a phone-based daily diary approach to survey older adults about their daily alcohol consumption, context of drinking (e.g. drinking alone), positive and negative affect, and their motives for drinking. Data were analyzed descriptively, and regression models were developed to examine associations between sociodemographic factors, affect, drinking context and motives, and alcohol consumption.

RESULTS

CCRC residents drank most frequently at home and were alone almost half of drinking days on average, although the context of drinking varied considerably by participant. Problem alcohol use was rare, but hazardous use due to specific comorbidities, symptoms and medications, and the amount of alcohol consumption was common. Respondents endorsed higher social motives for drinking and lower coping motives. Social motives were associated with decreased likelihood of drinking alone, but negative affect was associated with decreased likelihood of drinking outside one's home. Coping and social motives were associated with greater consumption, and higher positive affect was associated with lower consumption.

CONCLUSION

Among CCRC residents, alcohol use may be socially motivated rather than motivated by coping with negative affect. Future research should examine other motives for drinking in older adulthood. Evaluation of older adults living in CCRCs should include attention to health factors beyond problem use as other forms of hazardous use may be common in CCRCs.

Do women grow out of risky drinking? A prospective study of three cohorts of Australian women

INTRODUCTION AND AIMS

To examine women's drinking behaviour relative to Australian guidelines and identify associated factors over the lifespan.

DESIGN AND METHODS

Data came from three prospective cohorts of the Australian Longitudinal Study on Women's Health aged 18-23 (n = 14,247), 45-50 (n = 13,715) and 70-75 years (n = 12,432) when first surveyed in 1996. The same women were re-surveyed at roughly 3-year intervals until 2012. At each survey, four drinking behaviours were based on two guidelines: long-term drinking (no more than two standard drinks per day) and episodic drinking (no more than four standard drinks on an occasion): (i) no risk (within both guidelines); (ii) low episodic risk (less than once a month); high episodic risk (at least once a month); long-term risk (more than two drinks per day regardless of episodic drinking).

RESULTS

No risk drinking increased with age, low episodic risk drinking remained almost constant between ages 18 and 39, and high episodic risk drinking declined rapidly. Few women drank at long-term risk. Factors associated with risky drinking varied with age; however, being a past or current smoker consistently increased the risk, and risks for smokers increased with age. Risky drinking was less likely to be practised by women providing care and needing help with daily tasks, or by pregnant women and those living with children.

DISCUSSION AND CONCLUSIONS

Risky drinking behaviour should be addressed in younger women and in those who smoke. Interventions to reduce risky drinking, possibly in combination with reducing smoking, could be offered through general practice centres.

The effect of an educational intervention on alcohol consumption, at-risk drinking, and health care utilization in older adults: the Project SHARE study

OBJECTIVE

The purpose of this study was to examine the effectiveness of a patient-provider educational intervention in reducing at-risk drinking among older adults.

METHOD

This was a cluster-randomized controlled trial of 31 primary care providers and their patients ages 60 years and older at a community-based practice with seven clinics. Recruitment occurred from July 2005 to August 2007. Eligibility was determined by telephone and a baseline mailed survey. A total of 1,186 at-risk drinkers were identified by the Comorbidity Alcohol Risk Evaluation Tool. Follow-up patient surveys were administered at 3, 6, and 12 months after baseline. Study physicians and their patients were randomly assigned to usual care (n = 640 patients) versus the Project SHARE (Senior Health and Alcohol Risk Education) intervention (n = 546 patients), which included personalized reports, educational materials, drinking diaries, physician advice during office visits, and telephone counseling delivered by a health educator. Main outcomes were alcohol consumption, at-risk drinking (overall and by type), alcohol discussions with physicians, health care utilization, and screening and intervention costs.

RESULTS

At 12 months, the intervention was significantly associated with an increase in alcohol-related discussions with physicians (23% vs. 13%; p ≤ .01) and reductions in at-risk drinking (56% vs. 67%; p ≤ .01), alcohol consumption (-2.19 drinks per week; p ≤ .01), physician visits (-1.14 visits; p = .03), emergency department visits (16% vs. 25%; p ≤ .01), and nonprofessional caregiving visits (12% vs. 17%; p ≤ .01). Average variable costs per patient were $31 for screening and $79 for intervention.

CONCLUSIONS

The intervention reduced alcohol consumption and at-risk drinking among older adults. Effects were sustained over a year and may have been associated with lower health care utilization, offsetting screening and intervention costs.

The prevalence of food addiction as assessed by the Yale Food Addiction Scale: a systematic review

Obesity is a global issue and it has been suggested that an addiction to certain foods could be a factor contributing to overeating and subsequent obesity. Only one tool, the Yale Food Addiction Scale (YFAS) has been developed to specifically assess food addiction. This review aimed to determine the prevalence of food addiction diagnosis and symptom scores, as assessed by the YFAS. Published studies to July 2014 were included if they reported the YFAS diagnosis or symptom score and were published in the English language. Twenty-five studies were identified including a total of 196,211 predominantly female, overweight/obese participants (60%). Using meta-analysis, the weighted mean prevalence of YFAS food addiction diagnosis was 19.9%. Food addiction (FA) diagnosis was found to be higher in adults aged >35 years, females, and overweight/obese participants. Additionally, YFAS diagnosis and symptom score was higher in clinical samples compared to non-clinical counterparts. YFAS outcomes were related to a range of other eating behavior measures and anthropometrics. Further research is required to explore YFAS outcomes across a broader spectrum of ages, other types of eating disorders and in conjunction with weight loss interventions to confirm the efficacy of the tool to assess for the presence of FA.

Alcohol tax policy and related mortality. An age-period-cohort analysis of a rapidly developed Chinese population, 1981-2010

To delineate the temporal dynamics between alcohol tax policy changes and related health outcomes, this study examined the age, period and cohort effects on alcohol-related mortality in relation to changes in government alcohol policies. We used the age-period-cohort modeling to analyze retrospective mortality data over 30 years from 1981 to 2010 in a rapidly developed Chinese population, Hong Kong. Alcohol-related mortality from 1) chronic causes, 2) acute causes, 3) all (chronic+acute) causes and 4) causes 100% attributable to alcohol, as defined according to the Alcohol-Related Disease Impact (ARDI) criteria developed by the US Centers for Disease Control and Prevention, were examined. The findings illustrated the possible effects of alcohol policy changes on adult alcohol-related mortality. The age-standardized mortality trends were generally in decline, with fluctuations that coincided with the timing of the alcohol policy changes. The age-period-cohort analyses demonstrated possible temporal dynamics between alcohol policy changes and alcohol-related mortality through the period effects, and also generational impact of alcohol policy changes through the cohort effects. Based on the illustrated association between the dramatic increase of alcohol imports in the mid-1980s and the increased alcohol-related mortality risk of the generations coming of age of majority at that time, attention should be paid to generations coming of drinking age during the 2007–2008 duty reduction.

The relationship between labour market categories and alcohol use trajectories in midlife

Background and aims

Studies on the role of labour market position and change in alcohol use during midlife are scarce and their results are inconclusive mainly due to their failure to define comprehensive and distinct labour market groups and the short periods of time studied. In this study we used different activity categories for men and women to examine alcohol use trajectories in midlife covering a period of 17 years.

Methods

Using data from four sweeps of the National Child Development Study covering ages 33–50 (N=9960), we used multilevel growth models to study the association between labour market categories and longitudinal changes in weekly units of alcohol consumed.

Results

In the reference group of full-time employed men alcohol trajectory decreased over the follow-up period (β=−0.14; 95% CI −0.18 to −0.11) while in the reference group of employed women it increased (β=0.06; 95% CI 0.04 to 0.08). Men and women who were ‘mainly sick’ had significantly steeper declines in their alcohol consumption trajectory. Women who became employed after being homemakers had the steepest increase in alcohol use (β=0.05; 95% CI 0.01 to 0.09).

Conclusions

Being employed is a strong determinant of alcohol use for men and women in midlife, making the workplace a good target for health promotion programmes and policies aimed at reducing alcohol use. Caution is needed when interpreting the health effects of alcohol consumption as low alcohol users may have previously been heavy drinkers.

Three-year changes in drinking patterns in Spain: a prospective population-based cohort study

BACKGROUND

This study examined changes in alcohol drinking patterns (DP) and associated variables in a Mediterranean country.

METHODS

Changes in DP between baseline (2008-2010) and follow-up (2012-2013) were examined on a Spanish population-based cohort of 2254 adults (18-59 years) using multinomial logistic regression. Heavy consumption was defined as ≥40 g/day of alcohol in men (≥24 g/day in women) and binge drinking (BD) as the intake of ≥80 g of alcohol in men (≥60 g in women) on one occasion in the previous month. Six patterns were defined: (1) non-drinkers; (2) ex-drinkers; (3) moderate drinkers without BD (MNB); (4) moderate drinkers with BD (MB); (5) heavy drinkers without BD (HNB); and (6) heavy drinkers with BD (HB).

RESULTS

Overall, 45.2% of participants changed DP during follow-up. Over 24% of non-drinkers and 19.4% of ex-drinkers at baseline qualified as MNB at follow-up. The largest flow was from HNB to MNB (57.1%). Light-drinking patterns experienced the largest gains (ex-drinkers: 37.5% and MNB: 66.7%) by absorbing individuals lost by heavy-drinking patterns (MB: 50.8% and HNB: 48.4%). Men, younger individuals, and current smokers were more likely to report heavy-drinking patterns at one or both assessments. Being married or employed increased the likelihood of reporting light-drinking patterns at both surveys (p<0.05). Improving physical quality of life and exercise were associated with a shift from light- to heavy-drinking pattern during follow-up (p<0.05).

CONCLUSIONS

DP in Spain changed over 3 years with a tendency to "regress" toward moderate patterns. Repeated measures of alcohol intake may reduce classification errors and biased results when examining the impact of alcohol on health.

Substance abuse among older adults

Although the myth that older adults do not use mood-altering substances persists, evidence suggests that substance use among older adults has been underidentified for decades. The baby boom generation is unique in its exposure to, attitudes toward, and prevalence of substance use-causing projected rates of substance use to increase over the next twenty years. Given their unique biological vulnerabilities and life stage, older adults who misuse substances require special attention. Prevalence rates of substance use and misuse among older adults, methods of screening and assessment unique to older adults, and treatment options for older adults are reviewed.

Stability and change in alcohol habits of different socio-demographic subgroups--a cohort study

Background

Stability in alcohol habits varies over time and in subgroups, but there are few longitudinal studies assessing stability in alcohol habits by socio-demographic subgroups and potential predictors of stability and change. The aim was to study stability and change in alcohol habits by sex, age, and socio-economic position (SEP).

Methods

Data derived from two longitudinal population based studies in Sweden; the PART study comprising 19 457 individuals aged 20-64 years in 1998-2000, and the Stockholm Public Health Cohort (SPHC) with 50 067 individuals aged 18-84 years in 2002. Both cohorts were followed-up twice; PART 2000-2003 and 2010, and SPHC 2007 and 2010. Alcohol habits were measured with the Alcohol Use Disorders Identification Test (AUDIT), and with normal weekly alcohol consumption (NWAC). Stability in alcohol habits was measured with intraclass correlation. Odds ratios were estimated in multinomial logistic regression analysis to predict stability in alcohol habits.

Results

For the two drinking measures there were no consistent patterns of stability in alcohol habits by sex or educational level. The stability was higher for older age groups and self-employed women. To be a man aged 30-39 at baseline predicted both increase and decrease in alcohol habits.

Conclusions

The findings illustrate higher stability in alcohol habits with increasing age and among self-employed women with risky alcohol habits. To be a man and the age 30-39 predicted change in alcohol habits. No conclusive pattern of socio-economic position as predictor of change in alcohol habits was found and other studies of potential predictors seem warranted.

Cigarette smoking and postmenopausal breast cancer risk in a prospective cohort

Background:

The relationship between cigarette smoking and breast cancer risk has been inconsistent, potentially due to modification by other factors or confounding.

Methods:

We examined smoking and breast cancer risk in a prospective cohort of 186 150 female AARP (formerly American Association of Retired Persons) members, ages 50–71 years, who joined the study in 1995–96 by responding to a questionnaire. Through 2006, 7481 breast cancers were diagnosed. Multivariable-adjusted hazard ratios (HRs) were estimated, overall and stratified by breast cancer risk factors, using Cox proportional hazards regression. Multiplicative interactions were evaluated using the likelihood ratio test.

Results:

Increased breast cancer risk was associated with current (HR 1.19, 95% confidence interval (CI) 1.10–1.28) and former (HR 1.07, CI 1.01–1.13) smoking. The current smoking association was stronger among women without (HR 1.24, CI 1.15–1.35) as compared to those with a family history of breast cancer (HR 0.94, CI 0.78–1.13) (P-interaction=0.03). The current smoking association was also stronger among those with later (⩾15 years: HR 1.52, CI 1.20–1.94) as compared with earlier (⩽12 years: HR 1.14, CI 1.03–1.27; 13–14 years: HR 1.18, CI 1.05–1.32) ages at menarche (P-interaction=0.03).

Conclusions:

Risk was elevated in smokers, particularly in those without a family history or late menarche. Research into smoking's effects on the genome and breast development may clarify these relationships.

Secular changes in at-risk drinking in Sweden: birth cohort comparisons in 75-year-old men and women 1976-2006

Background: little is known about the prevalence of at-risk drinking in older adults.

Objective: to compare rates of at-risk drinking in 75-year-olds examined in 1976–77 and in 2005–06.

Design: cross-sectional survey.

Setting: two samples representative of the general population in Gothenburg, Sweden.

Participants: 75-year-olds born in 1901–02 (n = 303) and in 1930 (n = 753).

Methods: participants took part in a multidisciplinary study on health and ageing. Protocols regarding alcohol consumption were identical for both cohorts. Total weekly alcohol intake was estimated and at-risk drinking was defined as ≥100 g alcohol/week.

Results: the proportion abstaining differed significantly between birth cohorts (18% in 1976–77 versus 9% in 2005, P < 0.001). Frequencies of drinking beer and liquor were similar in the two cohorts for men, but were lower for women in the later-born cohort. Proportions drinking wine were higher in the later-born cohort for both sexes. Total weekly alcohol intake was higher for both men and women. At-risk drinking was observed in 19.3% of the men in the earlier-born cohort, and in 27.4% in the later-born cohort (P = 0.117). Corresponding figures for women were 0.6 and 10.4% (P < 0.001). At-risk drinking was significantly associated with birth cohort in women (OR: 13.77, CI: 1.82–104.0, P = 0.011) and the occupational group in men (OR: 1.60, CI: 1.13–2.26, P = 0.008).

Conclusions: alcohol consumption in 75-year-olds has changed markedly, especially in women. Studies need to be carried out in varied settings in order to evaluate the clinical and public health implications of changing trends in alcohol consumption.

Trend analysis and modelling of gender-specific age, period and birth cohort effects on alcohol abstention and consumption level for drinkers in Great Britain using the General Lifestyle Survey 1984-2009

BACKGROUND AND AIMS

British alcohol consumption and abstinence rates have increased substantially in the last 3 decades. This study aims to disentangle age, period and birth cohort effects to improve our understanding of these trends and suggest groups for targeted interventions to reduce resultant harms.

DESIGN

Age, period, cohort analysis of repeated cross-sectional surveys using separate logistic and negative binomial models for each gender.

SETTING

Great Britain 1984-2009.

PARTICIPANTS

Annual nationally representative samples of approximately 20 000 adults (16+) within 13 000 households.

MEASUREMENTS

Age (eight groups: 16-17 to 75+ years), period (six groups: 1980-84 to 2005-09) and birth cohorts (19 groups: 1900-04 to 1990-94). Outcome measures were abstinence and average weekly alcohol consumption. Controls were income, education, ethnicity and country.

FINDINGS

After accounting for period and cohort trends, 18-24-year-olds have the highest consumption levels (incident rate ratio = 1.18-1.15) and lower abstention rates (odds ratio = 0.67-0.87). Consumption generally decreases and abstention rates increase in later life. Until recently, successive birth cohorts' consumption levels were also increasing. However, for those born post-1985, abstention rates are increasing and male consumption is falling relative to preceding cohorts. In contrast, female drinking behaviours have polarized over the study period, with increasing abstention rates accompanying increases in drinkers' consumption levels.

CONCLUSIONS

Rising female consumption of alcohol and progression of higher-consuming birth cohorts through the life course are key drivers of increased per capita alcohol consumption in the United Kingdom. Recent declines in alcohol consumption appear to be attributable to reduced consumption and increased abstinence rates among the most recent birth cohorts, especially males, and general increased rates of abstention across the study period.

Focus on: women and the costs of alcohol use

Although light-to-moderate drinking among women is associated with reduced risks of some cardiovascular problems, strokes, and weakening of bones, such levels of drinking also are associated with increased risks of breast cancer and liver problems, and heavy drinking increases risks of hypertension and bone fractures and injuries. Women's heavy-drinking patterns and alcohol use disorders are associated with increased likelihood of many psychiatric problems, including depression, posttraumatic stress disorder, eating disorders, and suicidality, as well as increased risks of intimate partner violence and sexual assault, although causality in the associations of drinking with psychiatric disorders and with violence remains unclear. It is important for women to be aware of the risks associated with alcohol use, especially because gaps between U.S. men's and women's drinking may have narrowed. However, analyses of health risks and benefits need mprovement to avoid giving women oversimplified advice about drinking.

Predictive validity of the AUDIT for hazardous alcohol consumption in recently released prisoners

BACKGROUND

This study aimed to assess the predictive validity of the Alcohol Use Disorders Identification Test (AUDIT) among adult prisoners with respect to hazardous drinking following release, and identify predictors of post-release hazardous drinking among prisoners screening positive for risk of alcohol-related harm on the AUDIT.

METHODS

Data came from a survey-based longitudinal study of 1325 sentenced adult prisoners in Queensland, Australia. Baseline interviews were conducted pre-release with follow-up at 3 and 6 months post-release. We calculated sensitivity, specificity and area under the receiver operating characteristic (AUROC) to quantify the predictive validity of the AUDIT administered at baseline with respect to post-release hazardous drinking. Other potential predictors of hazardous drinking were measured by self-report and their association with the outcome was examined using logistic regression.

RESULTS

At a cut-point of 8 or above, sensitivity of the AUDIT with respect to hazardous drinking at 3-month follow-up was 81.0% (95%CI: 77.9-84.6%) and specificity was 65.6% (95%CI: 60.6-70.3%). The AUROC was 0.78 (95%CI: 0.75-0.81), indicating moderate accuracy. Among those scoring 8 or above, high expectations to drink post-release (AOR: 2.49; 95%CI: 1.57-3.94) and past amphetamine-type stimulant (ATS) use (AOR: 1.64; 95%CI: 1.06-2.56) were significantly associated with hazardous drinking at 3 months post-release. Results were similar at 6 months.

CONCLUSIONS

Among adult prisoners in our sample, pre-release AUDIT scores predicted hazardous drinking six months after release with acceptable accuracy, sensitivity and specificity. Among prisoners screening positive on the AUDIT, expectations of post-release drinking and ATS use are potential targets for intervention to reduce future hazardous drinking.

Less drinking, yet more problems: understanding African American drinking and related problems

Researchers have found that, compared to European Americans, African Americans report later initiation of drinking, lower rates of use, and lower levels of use across almost all age groups. Nevertheless, African Americans also have higher levels of alcohol problems than European Americans. After reviewing current data regarding these trends, we provide a theory to understand this apparent paradox as well as to understand variability in risk among African Americans. Certain factors appear to operate as both protective factors against heavy use and risk factors for negative consequences from use. For example, African American culture is characterized by norms against heavy alcohol use or intoxication, which protects against heavy use but also provides within-group social disapproval when use does occur. African Americans are more likely to encounter legal problems from drinking than European Americans, even at the same levels of consumption, perhaps thus resulting in reduced consumption but more problems from consumption. There appears to be one particular group of African Americans, low-income African American men, who are at the highest risk for alcoholism and related problems. We theorize that this effect is due to the complex interaction of residential discrimination, racism, age of drinking, and lack of available standard life reinforcers (e.g., stable employment and financial stability). Further empirical research will be needed to test our theories and otherwise move this important field forward. A focus on within-group variation in drinking patterns and problems is necessary. We suggest several new avenues of inquiry.

Prevalence and Patterns of Alcohol Misuse in a Community-Dwelling Elderly Sample in Brazil

Objective: The aim of this study was to estimate prevalence and patterns of lifetime alcohol misuse. Method: This was a cross-sectional study of a representative sample of 1,078 individuals aged 60 or more. Structured interview included sociodemographic, lifestyle, health data, and the five alcohol misuse screening questions of the Self-Reporting Questionnaire. Results: Prevalence of misuse was 6.5%. Men, aged 60 to 69, low educational level, separated/divorced, and tobacco smoking were independently associated with lifetime alcohol misuse. Odds ratios show increasing association with levels of alcohol misuse groups in males, low-educated, and tobacco users. Persons aged 60 to 69, 4 to 7 education years, and non-White ethnicity were significantly associated with the major alcohol misuse score. Discussion: Younger elderly were more exposed to alcohol than previous cohorts. Thus, problems with alcohol in old age will possibly increase as they grow older. The results of this study call attention to a field of lacking evidence in alcohol-related problems of older persons.

The relationship between midlife and late life alcohol consumption, APOE e4 and the decline in learning and memory among older adults

AIMS

The aim of the study was to determine whether the trajectory of learning and memory is modified according to an interaction between midlife or late life alcohol consumption status and the presence of one or more APOE e4 alleles.

METHODS

This was a secondary analysis of cognitive, genetic and alcohol consumption data collected from members of the Framingham Heart Study Offspring Cohort.

RESULTS

Light and moderate alcohol consumption during late life was associated with greater decline in learning and memory among APOE e4 carriers, whereas light and moderate alcohol consumption was associated with an increase in learning and memory among non-APOE e4 carriers. There was not a significant interaction between midlife alcohol consumption status and APOE e4 on the trajectory of learning and memory.

CONCLUSION

Light to moderate alcohol consumption during late life may protect against a decline in learning and memory for non-APOE e4 allele carriers, but not for older adults who carry one or more APOE e4 alleles.

Occupational factors and problem drinking among a Japanese working population

Problem drinking is a serious public health problem in the workplace. However, few Japanese epidemiological studies have investigated the occupational characteristics of problem drinking. The purpose of this study is to clarify the occupational risk factors for problem drinking among a Japanese working population. We used data from a random-sampling survey about mental health and suicide, conducted among Hamamatsu City residents aged 15 to 79 yr old during May and June in 2008. The relation between occupational factors and problem drinking was analyzed with multiple logistic regression models stratified by gender. CAGE questionnaire was used to assess problem drinking. With regard to employment types, problem drinkers were more prevalent among self-employed women. With regard to occupational types, clerical and service professions had more problem drinkers of either sex, while administrative/managerial and sales professions had more women with such problem. With regard to company size, male problem drinkers were more prevalent in smaller companies than in larger ones. These results indicate that the prevalence of problem drinkers in the workplace depends on where one works. It is necessary to consider these characteristics to provide effective measures to address problem drinking in the workplace.

Why do older unhealthy drinkers decide to make changes or not in their alcohol consumption? Data from the Healthy Living as You Age study

OBJECTIVES

To understand characteristics of older at-risk drinkers and reasons why they decide to change or maintain their alcohol consumption.

DESIGN

Secondary analysis of data from a randomized controlled trial to reduce drinking in at-risk drinkers.

SETTING

Three primary care sites in southern California.

PARTICIPANTS

Six hundred thirty-one adults aged 55 and older who were at-risk drinkers at baseline, 521 of whom who completed a 12-month assessment.

MEASUREMENTS

Sociodemographic and alcohol-related characteristics of 12-month assessment completers and noncompleters and among those completing the 12-month assessment by telephone or mail were compared using descriptive statistics. Reasons why respondents maintained or changed average alcohol consumption were asked of those who completed a 12-month assessment by telephone. Factors that might motivate at-risk drinkers to reduce drinking were asked about, and frequencies were calculated for these responses.

RESULTS

Participants were primarily male, white, highly educated, and in good health. Those who responded to the 12-month assessment by mail were more likely to be working, to be in the intervention arm, and to drink more. Most who reduced alcohol consumption and heavy drinking did so because they thought it would benefit them. Those who did not thought that drinking was not a problem for them. Both groups cited their environment and circumstances as influencing their drinking. Remaining at-risk drinkers reported that medical evidence that alcohol was harming them would motivate them to reduce drinking.

CONCLUSION

Older adults report that they reduce their drinking when they recognize that their drinking habits may be causing them harm; one's environment can hinder or help one to reduce drinking.

Changes in alcohol intake and their relationship with health status over a 24-year follow-up period in community-dwelling older adults

OBJECTIVES

To determine whether alcohol use changes over time in older adults and whether alcohol intake is associated with common chronic diseases.

DESIGN

Twenty-four-year longitudinal study.

SETTING

Southern California community.

PARTICIPANTS

One thousand seventy-six members of the Rancho Bernardo cohort aged 50 to 89 at baseline.

MEASUREMENTS

Participants completed two to six research visits at approximately 4-year intervals between 1984 and 2009. At each visit, participants completed standard questionnaires on alcohol use, chronic diseases, and behaviors. Mixed-effects linear models were used to examine changes in average weekly alcohol intake over time and in relationship to health status.

RESULTS

Prevalence and frequency of alcohol use was high throughout the study, with more than 60% of participants reporting weekly alcohol intake. The average amount consumed declined with advancing age, regardless of the presence of any of the eight most common chronic diseases. Prevalence of drinking in excess of age- and sex-specific low-risk guidelines was high across all visits and did not vary according to disease burden. At the final visit, 29% of participants drank in excess of low-risk drinking guidelines, including 28% of those with hypertension and 31% with diabetes mellitus.

CONCLUSION

Prevalence and frequency of alcohol intake remained stable over a 24 year follow-up in this cohort of educated, white, middle-class, older adults, although average amount consumed decreased with advancing age. Despite this decrease, a high proportion of older adults, including those with common chronic health conditions, drank in excess of current guidelines. Clinicians should provide more education on the importance of older adults moderating alcohol intake.

Income inequality, alcohol use, and alcohol-related problems

OBJECTIVES

We examined the relationship between state-level income inequality and alcohol outcomes and sought to determine whether associations of inequality with alcohol consumption and problems would be more evident with between-race inequality measures than with the Gini coefficient. We also sought to determine whether inequality would be most detrimental for disadvantaged individuals.

METHODS

Data from 2 nationally representative samples of adults (n = 13,997) from the 2000 and 2005 National Alcohol Surveys were merged with state-level inequality and neighborhood disadvantage indicators from the 2000 US Census. We measured income inequality using the Gini coefficient and between-race poverty ratios (Black-White and Hispanic-White). Multilevel models accounted for clustering of respondents within states.

RESULTS

Inequality measured by poverty ratios was positively associated with light and heavy drinking. Associations between poverty ratios and alcohol problems were strongest for Blacks and Hispanics compared with Whites. Household poverty did not moderate associations with income inequality.

CONCLUSIONS

Poverty ratios were associated with alcohol use and problems, whereas overall income inequality was not. Higher levels of alcohol problems in high-inequality states may be partly due to social context.

Predicting 10-year alcohol use trajectories among men age 50 years and older

OBJECTIVE

To describe common 10-year drinking trajectories followed by men age 50 years or older and identify risk factors for those trajectories.

DESIGN

Longitudinal data were used to derive a semiparametric group-based model.

PARTICIPANTS

Men from the Health and Retirement Study age 50-65 years in 1998 who completed three or more of the six interviews conducted from 1998 to 2008, including our 1998 baseline interview.

MEASUREMENTS

Biannual data on number of drinks per drinking day were used to derive drinking trajectories. Risk factors included baseline age, race, ethnicity, education, marital status, retirement, smoking, binge drinking, vigorous exercise, body mass index, depression, pain, self-reported health, and chronic disease.

RESULTS

The best-fitting model included consistent infrequent drinkers and nondrinkers (40.6% of cohort), increasing drinkers (5.5%), decreasing drinkers (7.6%), consistent at-risk drinkers (15.6%), and consistent moderate drinkers (30.7%). Adjusted logistic regression models comparing men with similar 1998 drinking levels who subsequently followed different trajectories identified significant risks associated with age, education, smoking, binge drinking, depression, pain, and self-reported health. To illustrate, odds ratios (ORs) and 95% confidence intervals (95% CIs) suggest that baseline infrequent drinkers were less likely to follow an increasing drinkers trajectory if they were older (OR: 0.57, 95% CI: 0.38-0.82) and smoked cigarettes (OR: 0.47, 95% CI: 0.30-0.74). Baseline drinkers were less likely to follow a decreasing trajectory if they reported more than 12 years of education (OR: 0.58, 95% CI: 0.42-0.82) and thought that their health was excellent or very good (OR: 0.54, 95% CI: 0.39-0.76).

CONCLUSION

Only 30.7% of older men in this cohort were moderate drinkers throughout the follow-up. Many older men may benefit from brief counseling on the risks and benefits of drinking.

Alcohol-specific parenting, adolescent alcohol use and the mediating effect of adolescent alcohol-related cognitions

OBJECTIVES

Previous research indicated that alcohol-specific parenting is an important precursor of adolescent alcohol use, but failed to define the underlying mechanism. Based on social cognitive theory, alcohol-related cognitions such as alcohol refusal self-efficacy and alcohol-related expectancies were hypothesised to mediate this link.

DESIGN

A cross-sectional survey included 1349 mothers and their sixth grade (11-12 years old) adolescent offspring. Structural equation modelling was employed to test the association between alcohol-specific parenting and adolescent alcohol use, mediated by adolescent alcohol-related cognitions.

MAIN OUTCOME MEASURES

Adolescent alcohol use, drinking refusal self-efficacy and alcohol expectancies.

RESULTS

The associations between frequency of communication, maternal alcohol use and adolescent alcohol use were mediated by negative alcohol-related expectancies. The associations between quality of communication, rules and disclosure and adolescent alcohol use were mediated by self-efficacy.

CONCLUSIONS

The present study provides a first indication that the underlying mechanism of the association between the most important alcohol-specific parenting practices and adolescent alcohol use can be contributed to the mediating effect of alcohol-refusal self-efficacy.

Drinking habits of older Canadians: a comparison of the 1994 and 2004 national surveys

ABSTRACT This study examines changes in the alcohol consumption of Canadians aged 55 and older from the 1990s to the 2000s and investigates whether the differences persist after controlling for the socio-demographic composition of the samples. The data included two subsamples of respondents 55 to 74 years of age from two cross-sectional Canadian surveys: the 1994 CADS (1,071 men and 1,446 women) and the 2004 GENACIS (1,494 men and 2,176 women). One-way ANOVAs revealed significantly higher rates of drinkers and binge drinking in 2004 but no differences in drinking profiles. Regression analyses showed that the observed differences did not disappear when controlling for socio-demographic composition. The higher rates of drinkers in 2004 may be explained by a social and environmental context that was more favourable to alcohol consumption in the 2000s. More research is needed to disentangle the age-cohort-period effects on alcohol consumption among Canadian older adults.

Changes in drinking behavior among control group participants in early intervention studies targeting unhealthy alcohol use recruited in general hospitals and general practices

BACKGROUND

This study aims to analyze the influence of setting variables on drinking behavior in patients with unhealthy alcohol consumption recruited proactively in general medical practices (GP) and internal and surgical wards of two general hospitals (GH) assigned to control groups.

METHOD

This analysis compared two control groups of RCTs targeting unhealthy alcohol consumption: one outpatient sample (GP; n=99) with one inpatient sample (GH; n=173). Both groups were recruited via systematic screening of all patients aged between 18 and 64 years and were included in the studies if drank above the at-risk criteria of the British Medical Association (20/30 g alcohol/daily) and/or fulfilled criteria of alcohol abuse or - dependence according to DSM-IV. Both samples received a non-alcohol specific brochure on healthy living after study inclusion and were re-assessed 12 months later.

RESULTS

GH patients were significantly older, included of more males, had received less schooling and had a higher readiness to change at baseline than GP patients. Groups did not differ concerning alcohol-related diagnoses or smoking status. At the 12-month follow-up, significantly more GH patients revealed abstinence or drinking below the inclusion criteria (50.0% vs. 26.1%, p<.001). In a multivariate analysis, medical setting (GH vs. GP) remained a significant predictor for non-problematic drinking or abstinence even after controlling for baseline differences between groups.

CONCLUSIONS

Findings suggest that untreated change from problematic alcohol use may be more intense after non-alcohol-related inpatient treatment than after having been a GP patient. Implications for brief interventions in inpatients are discussed.

Perceived social support and preventive health behavioral outcomes among older women

Although research has documented that social support is a positive pathway to healthpromoting behavioral practices, very few longitudinal studies have assessed the relationship between social support and health-promoting behaviors among older, diverse women. Three waves of data from the Americans' Changing Lives (ACL) survey assessed whether or not changes in perceived social support influenced behavioral outcomes among 671 African American women and non-Hispanic white women aged 60 years and older. Positive social support from friends was the most successful in predicting physical activity across the life span while positive spousal support, positive support from children, and health behavior-specific support were insignificant determinants of physical activity. The results suggest that social support from friends may be an important predictive factor in engaging older women in physical activity during the aging process.

Prospective evaluation of mental health and deployment experience among women in the US military

Previous research has shown that military women often experience potentially severe health outcomes following deployment. Data from the Millennium Cohort Study, a 21-year longitudinal study examining the health effects of military service, were used to examine this issue. In longitudinal analyses (2001-2008) carried out among US military women (n = 17,481), the authors examined positive screens for depression, anxiety, panic, and posttraumatic stress disorder in relation to deployment in support of the operations in Iraq and Afghanistan, while adjusting for relevant baseline and time-varying covariates. Women who were deployed and reported combat-related exposures had greater odds than nondeployed women of reporting symptoms of a mental health condition (odds ratio = 1.91, 95% confidence interval: 1.65, 2.20), after adjustment for demographic, military, and behavioral covariates. In addition, higher stress, problem drinking, and a history of mental illness were significantly associated with increased risk of later mental health conditions. In contrast, women in the Reserves or National Guard and those with higher education were at decreased risk of mental health conditions (all P 's < 0.01). As the roles and responsibilities of women in the military expand and deployments continue, designing better prevention and recovery strategies specifically for women are critical for overall force health protection and readiness.

Developmental trajectory and environmental moderation of the effect of ALDH2 polymorphism on alcohol use

BACKGROUND

In the aldehyde dehydrogenase 2 (ALDH2) gene, the ALDH2*2 allele, prevalent in East Asian populations, encodes an enzyme with severely reduced activity, thereby disrupting the normal metabolism of alcohol. Possession of the ALDH2*2 allele has been repeatedly shown to be associated with lower risk for alcohol dependence and reduced alcohol use. However, relatively few studies have considered whether the magnitude of the effect of ALDH2 polymorphism upon drinking is related to developmental stage or varies by environmental context.

METHODS

In a longitudinally assessed sample of 356 adopted adolescents and young adults of East Asian descent, we examined the progression over time of the relationship between ALDH2 genotype and multiple measures of drinking behavior. We also sought to determine whether the environmental influences of nonbiological parent and elder sibling alcohol use and misuse, as well as deviant peer behavior, moderated the effect of ALDH2 genotype upon alcohol use.

RESULTS

Across all measures of alcohol use, the association between ALDH2*2 allele possession and reduced drinking went from negligible to moderate between mid-adolescence and early adulthood. A combined index of adoptive parent alcohol use and misuse consistently moderated the protective effect of the ALDH2*2 allele across the measures of quantity and frequency of alcohol use, and symptomology, such that high parental alcohol use and misuse reduced the protective effect of the ALDH2*2 allele, while low parental alcohol use and misuse enhanced the effect of the allele. Neither a combined index of elder sibling alcohol use and misuse, nor deviant peer behavior was consistently related to the effect of ALDH2 genotype.

CONCLUSIONS

The protective effect of the ALDH2*2 allele increases over the course of adolescence and young adulthood and is modified by the environmental influence of parental alcohol use and misuse. As such, ALDH2 provides a model system for exploring the nature of gene-environment interplay across development.

Interactive influences of neighborhood and individual socioeconomic status on alcohol consumption and problems

AIMS

To assess cross-level interactions between neighborhood and individual socioeconomic status (SES) on alcohol consumption and problems, and investigate three possible explanations for such interactions, including the double jeopardy, status inconsistency and relative deprivation hypotheses.

METHODS

Data from the 2000 and 2005 US National Alcohol Surveys were linked to the 2000 US Census to define respondent census tracts as disadvantaged, middle-class and advantaged. Risk drinking (consumption exceeding national guidelines), monthly drunkenness and alcohol problems were examined among low-, middle- and high-SES past-year drinkers (n = 8728). Gender-stratified, multiple logistic regression models were employed, and for outcomes with a significant omnibus F-test, linear contrasts were used to interpret interactions.

RESULTS

Cross-level SES interactions observed for men indicated that residence in advantaged neighborhoods was associated with markedly elevated odds of risk drinking and drunkenness for low-SES men. Linear contrasts further revealed a nearly 5-fold increased risk for alcohol problems among these men, relative to middle-SES and high-SES men also living in advantaged neighborhoods. Among women, neighborhood disadvantage was related to increased risk for alcohol problems, but there were no significant SES interactions. These findings did not support theories of double jeopardy and status inconsistency.

CONCLUSION

Consistent with the relative deprivation hypothesis, findings highlight alcohol-related health risks among low-SES men living in affluent neighborhoods. Future research should assess whether this pattern extends to other health risk behaviors, investigate causal mechanisms and consider how gender may influence these.

Secular trends in prevalence of alcohol use disorder and its correlates in Korean adults: results from Korea National Health and Nutrition Examination Survey 2005 and 2009

The Alcohol Use Disorders Identification Test (AUDIT) has been found to provide an accurate measure for risk of hazardous and harmful alcohol use, as well as possible dependence. Data from 2 representative samples of 7693 adults in the Korea National Health and Nutrition Examination Survey (KNHANES) 2005 and 6276 participants in 2009 were analyzed. The overall age-adjusted prevalence of alcohol use disorder (AUD) in 2009 (38.8%) was higher than that in 2005 (32.7%), with a difference of 6.1% (95% confidence interval [CI], 2.9%-9.3%; P = .0002). Men were about 7 times as likely as women to meet the criteria for AUD (odds ratio [OR] = 7.16; 95% CI, 6.27-8.17). Current smoking was the most important correlate associated with AUD in both genders (women: OR = 6.03; 95% CI, 4.40-8.27; men: OR = 2.83; 95% CI, 2.29-3.48). Among women, unmarried (OR = 1.76; 95% CI, 1.35-2.31), less than high school education (OR = 2.71, 95% CI, 1.86-3.96), and lowest income (OR = 1.45, 95% CI, 1.06-1.97) were associated with AUD. These findings provide the most updated prevalence estimates of AUD in the Korean population and they highlight its strong association with smoking, gender differences, and lower socioeconomic status in the Korean population.

Differences between the factors affecting high-risk drinking and those affecting smoking in Korea

This study examines the factors influencing high-risk drinking and cigarette smoking and assesses the differences in those factors between 2 risky behaviors in Korea. A national, cross-sectional health behavior survey was performed on 12,303 households in 2006 and a data set of 2925 adult males was analyzed using bivariate probit estimation model. The likelihood of high-risk drinking rose with an increase in the level of income, whereas that of smoking was lowest in a medium income. White-collar workers were more at risk of high-risk drinking than blue-collar workers. Conversely, blue-collar workers tended to smoke more frequently than white-collar workers. Body mass index showed a positive association with high-risk drinking, but it had no significant relationship with smoking. Significant differences may exist in associations between factors influencing high-risk drinking and those influencing smoking. The comprehensive understanding of these differences would allow for the development of appropriate public health programs.

Identifying socio-demographic and socioeconomic determinants of health inequalities in a diverse London community: the South East London Community Health (SELCoH) study

Background

Responses to public health need require information on the distribution of mental and physical ill health by demographic and socioeconomic factors at the local community level.

Methods

The South East London Community Health (SELCoH) study is a community psychiatric and physical morbidity survey. Trained interviewers conducted face-to-face computer assisted interviews with 1698 adults aged 16 years and over, from 1076 randomly selected private households in two south London boroughs. We compared the prevalence of common mental disorders, hazardous alcohol use, long standing illness and general physical health by demographic and socioeconomic indicators. Unadjusted and models adjusted for demographic and socioeconomic indicators are presented for all logistic regression models.

Results

Of those in the sample, 24.2% reported common mental disorder and 44.9% reported having a long standing illness, with 15.7% reporting hazardous alcohol consumption and 19.2% rating their health as fair or poor. The pattern of indicators identifying health inequalities for common mental disorder, poor general health and having a long term illness is similar; individuals who are socioeconomically disadvantaged have poorer health and physical health worsens as age increases for all groups. The prevalence of poor health outcomes by ethnic group suggests that there are important differences between groups, particularly for common mental disorder and poor general health. Higher socioeconomic status was protective for common mental disorder, fair or poor health and long standing illness, but those with higher socioeconomic status reported higher levels of hazardous alcohol use. The proportion of participants who met the criteria for common mental disorder with co-occurring functional limitations was similar or greater to those with poor physical health.

Conclusions

Health service providers and policy makers should prioritise high risk, socially defined groups in combating inequalities in individual and co-occurring poor mental and physical problems. In population terms, poor mental health has a similar or greater burden on functional impairment than long term conditions and perceived health.

Older adults' own reasoning for their alcohol consumption

OBJECTIVE

The aim of the study was to investigate what the older adults themselves consider to be the reasons for their alcohol consumption.

METHODS

The data were collected with a postal questionnaire from a random sample of 2100 elderly people (≥65 years) living in the medium-sized city of Espoo, Finland. The response rate was 71.6% from the community-dwelling sample. Altogether 868 persons responded that they use alcohol. Of them, 831 gave reasons for their drinking. We defined "at-risk users" as consuming >7 drinks per week, or ≥5 drinks on a typical drinking day, or using ≥3 drinks several times per week.

RESULTS

Main reasons given for alcohol consumption were "having fun or celebration" (58.7%), "for social reasons" (54.2%), "using alcohol for medicinal purposes" (20.1%), and "with meals" (13.8%). Younger age groups reported more often than the older age groups that they use alcohol for "having fun or celebration" and "for social reasons." The older age groups used more often "alcohol for medicinal purposes". Men used alcohol more often than women "as pastime" or "as sauna drink". Those defined as "at-risk users" reported using alcohol because of "meaningless life," for "relieving depression," "relieving anxiety," and "relieving loneliness."

CONCLUSIONS

Older adults have diverse alcohol consumption habits like people in other age groups. The oldest olds reported that they use alcohol for medicinal purposes. The "at-risk users" admit they use alcohol because of meaningless life, and relieving depression, anxiety, and loneliness.

Prevalence of at-risk drinking among older adults and associated sociodemographic and health-related factors

OBJECTIVES

Recognition of alcohol-related health problems in the elderly is challenging. Alcohol use also tends to be a hidden issue. The aim of this study was to examine the prevalence and at-risk drinking patterns in community-dwelling older adults and their associations with socio-demographic and health-related factors.

DESIGN

The data were collected with a postal questionnaire from a random sample of 2100 elderly people (≥ 65 years) living in the medium-sized city of Espoo, Finland. The response rate was 71.6% from the community-dwelling sample. We defined the amount of at-risk drinking as 1) consuming >7 drinks per week or 2) >5 drinks on a typical drinking day or 3) using >3 drinks several times per week.

RESULTS

Of the respondents, 8.2% (N=114) were at-risk drinkers. At-risk drinking was associated with younger age and male sex, higher level of education, good income, living with a spouse, and current smoking. In addition, good functioning was associated with at-risk drinking. Although frequency and quantity of alcohol consumption declined with age, of our respondents nearly one-fifth of men aged 71-80 years and one-tenth of men aged 81-90 years could be classified as at-risk drinkers. At-risk drinkers had comorbidities and multiple medications as often as non-risk group. A significantly larger proportion of the at-risk drinking group relative to the non-risk group admitted falling or injuring themselves (5.3% vs. 0.7%) or forgotten to take their medications because of the use of alcohol.

CONCLUSIONS

At-risk drinking is prevalent among older adults, particularly among males, despite prevalent comorbidities and multiple medications. At-risk drinking is associated with adverse events such as a tendency for injuries.

Prevalence of alcoholic liver disease among Korean adults: results from the fourth Korea National Health and Nutrition Examination Survey, 2009

BACKGROUND/AIM

Alcohol consumption continues to be a common cause of acute and chronic liver disease.

METHODS

Data from a representative sample of 7,893 adults in the Korean National Health and Nutrition Examination Survey 2009 were analyzed. Alcoholic liver disease (ALD) was defined through heavy alcohol consumption (≥40 g/day for men or ≥20 g/day for women) and through elevated liver tests.

RESULTS

Approximately 6.7% (95% confidence interval [CI], 6.0-7.4) was at heavy alcohol consumption. Of these "heavy alcohol consumers", one quarter also had ALD. The prevalence of ALD was 1.7% (95% CI, 1.3-2.1).

CONCLUSION

ALD is still a burden in the Korean population.

Alcohol-Related Problems among Sexual Minority Women

In this article I describe the historical context for research on sexual minority women's drinking, including the age-old tendency to link homosexuality and alcoholism; I summarize gaps and limitations that characterized much of the research on sexual minority women's drinking over the past several decades; and I review recent literature to highlight progress in the field-with a particular focus on my own research related to risk and protective factors for heavy drinking and drinking-related problems among sexual minority women. I conclude with a discussion of barriers to treatment for sexual minority women and recommendations for substance abuse treatment providers.

Twenty-year alcohol-consumption and drinking-problem trajectories of older men and women

OBJECTIVE

The aim of this study was to describe older adults' 20-year alcohol-consumption and drinking-problem trajectories, identify baseline predictors of them, and determine whether older men and women differ on late-life drinking trajectory characteristics and predictors.

METHOD

Two-group simultaneous latent growth modeling was used to describe the characteristics and baseline predictors of older community-residing men's (n = 399) and women's (n = 320) 20-year drinking trajectories. Chi-square difference tests of increment in fit of latent growth models with and without gender invariance constraints were used to determine gender differences in drinking trajectory characteristics and predictors.

RESULTS

Unconditional quadratic growth models best described older individuals' within-individual, 20-year drinking trajectories, with alcohol consumption following an average pattern of delayed decline, and drinking problems an average pattern of decline followed by leveling off. On average, older men declined in alcohol consumption somewhat later than did older women. The best baseline predictors of more rapid decline in alcohol consumption and drinking problems were drinking variables indicative of heavier, more problematic alcohol use at late middle age.

CONCLUSIONS

The course of alcohol consumption and drinking problems from late middle age onward is one of net decline, but this decline is neither swift nor invariable. Gender differences in the timing of decline in drinking suggest that ongoing monitoring of alcohol consumption may be especially important for older men. Further research is needed to identify factors known at late middle age that prospectively explain long-term change in late-life use of alcohol.

Birth cohort effects and gender differences in alcohol epidemiology: a review and synthesis

BACKGROUND

Alcohol consumption has demonstrated substantial temporal trends, with some evidence suggesting strong birth cohort effects. The identification of at-risk birth cohorts can inform the interpretation of alcohol trends across age, time, and demographic characteristics such as gender. The present literature review has 2 objectives. First, we conduct a cross-national review of the literature on birth cohort differences in alcohol consumption, disorder, and mortality. Second, we determine the consistency of evidence for birth cohort effects on gender differences.

METHODS

A search was conducted and key data on population characteristics, presence and direction of cohort effects, and interactions with gender compiled. Thirty-one articles were included.

RESULTS

Evidence suggests that younger birth cohorts in North America, especially those born after World War II, are more likely than older cohorts to engage in heavy episodic drinking and develop alcohol disorders, but this cohort effect is not found in Australia and western Europe. Cross-nationally, substantial evidence indicates that women in younger cohorts are at especially high risk for heavy episodic drinking and alcohol disorders.

DISCUSSION

Younger birth cohorts in North America and Europe are engaging in more episodic and problem drinking. The gender gap in alcohol problems is narrowing in many countries, suggesting shifting social norms surrounding gender and alcohol consumption. These trends suggest that public health efforts to specifically target heavy drinking in women are necessary.

Joe Sixpack: Normality, deviance, and the disease model of alcoholism

The advantages of the disease model of alcoholism are well known, but the disadvantages have received little attention. The model's dominance has forestalled consideration of alternative and potentially valuable theories. It reinforces the value of normality even as it marks alcoholics as deviant. It suggests problem drinkers can diagnose themselves. These disadvantages are traceable to narrowly constructed scientific discourses: science-as-positivism, alcoholism-as-disease, and the individual-as-scientist. As a result, problem drinkers pondering a diagnosis of alcoholism emphasize the positivist concepts of central tendency, objectivity, and prediction/control. Positivism reinforces the value of normality even as a disease diagnosis threatens to mark the personal identity as deviant. In this circumstance, continuing to drink while manipulating drinking variables is rational. Alcoholism theory would benefit if researchers extended conceptualizations beyond the disease model. Alcoholism treatment would benefit if treatment professionals challenged social norms, emphasized subjectivity, and determined the parameters of the drinker’s self-control.

Estimating older hazardous and binge drinking prevalence using AUDIT-C and AUDIT-3 thresholds specific to older adults

BACKGROUND

This study aimed to provide hazardous and binge drinking prevalence, odds and risk attributable to specific demographic correlates in community dwelling older adults using both the standard and new older-specific AUDIT-C thresholds.

METHODS

Hazardous drinking was assessed using the AUDIT-C in a cross-sectional postal survey of 6662 New Zealanders aged 55-70 years old (m=60.94, SD=4.70) randomly selected from the New Zealand Electoral Roll. Prevalence data is presented for whole sample and stratified by key demographic correlates using standard and older-specific threshold scores on the AUDIT-C. Hazardous drinking prevalence using the standard AUDIT-C threshold was 56.01%, as compared to 42.28% and 50.20% under two older-specific thresholds.

RESULTS

Being younger, male, and wealthy were consistent drinking predictors across thresholds but the older-specific thresholds substantially altered the prevalence and risk for females, Asians, and poorer people. Past-month binge prevalence of 18.18% was considerably lower than the past-year prevalence of 33.51%, but change from past-month to past-year binge threshold had no significant effect on the demographic composition of binge drinkers. The standard AUDIT-C threshold over-estimates hazardous drinking prevalence in older adults by up to 33%, but even the most conservative rates in this study are cause for concern regarding the level of drinking by older people in New Zealand.

CONCLUSION

Older hazardous drinkers are predominantly younger, wealthier, white, partnered males, whichever threshold is used, but binge drinkers are more likely to be rural, Māori, and lack tertiary education. Further efforts are needed to determine factors underpinning hazardous drinking, especially in older Māori.

Age and gender as moderators of the relationship between physical activity and alcohol use

OBJECTIVE

Understanding moderators of the relationship between physical activity (PA) and alcohol use is important for clarifying the mechanisms underlying these behaviors and informing health promotion interventions. This study examined age and gender as two candidate moderators of the PA-alcohol use link.

METHOD

As part of a correlational, cross-sectional population-based study of US 34,653 adults, participants were administered surveys assessing demographics, alcohol use, moderate and vigorous PA, and other characteristics. Composite indices of the frequency and quantity of alcohol use and PA were utilized in analyses.

RESULTS

Age moderated the association between past-year vigorous PA and alcohol use (ps ≤ .01). Vigorous PA was positively associated with alcohol use in individuals under 50 years of age (ps ≤ .05), but not in individuals over 50 years of age (ps ≥ 0.05). Gender moderated the association between past-year moderate PA and alcohol use (ps<.001). The relation was stronger in males (β=.72) than in females (β=.41). Each of the findings remained significant even when controlling for demographics, psychiatric variables, and other potential confounds.

CONCLUSION

Among the American population of adults, age appears to moderate the relationship between vigorous PA and alcohol use, whereas gender appears to moderate the relationship between moderate PA and alcohol use. These findings shed light on the underlying mechanisms that may account for increased alcohol use in exercisers and may have clinical implications for alcohol screening and interventions in adults who lead active lifestyles.

Stable genetic effects on symptoms of alcohol abuse and dependence from adolescence into early adulthood

Relatively little is known about how genetic influences on alcohol abuse and dependence (AAD) change with age. We examined the change in influence of genetic and environmental factors which explain symptoms of AAD from adolescence into early adulthood. Symptoms of AAD were assessed using the four AAD screening questions of the CAGE inventory. Data were obtained up to six times by self-report questionnaires for 8,398 twins from the Netherlands Twin Register aged between 15 and 32 years. Longitudinal genetic simplex modeling was performed with Mx. Results showed that shared environmental influences were present for age 15-17 (57%) and age 18-20 (18%). Unique environmental influences gained importance over time, contributing 15% of the variance at age 15-17 and 48% at age 30-32. At younger ages, unique environmental influences were largely age-specific, while at later ages, age-specific influences became less important. Genetic influences on AAD symptoms over age could be accounted for by one factor, with the relative influence of this factor differing across ages. Genetic influences increased from 28% at age 15-17 to 58% at age 21-23 and remained high in magnitude thereafter. These results are in line with a developmentally stable hypothesis that predicts that a single set of genetic risk factors acts on symptoms of AAD from adolescence into young adulthood.

Increasing and decreasing alcohol use trajectories among older women in the U.S. across a 10-year interval

Older women who routinely drink alcohol may experience health benefits, but they are also at risk for adverse effects. Despite the importance of their drinking patterns, few studies have analyzed longitudinal data on changes in drinking among community-based samples of women ages 50 and older. Reported here are findings from a semi-parametric group-based model that used data from 4,439 randomly sampled U.S. women who enrolled in the Health and Retirement Study (HRS) and completed ≥ 3 biannual alcohol assessments during 1998-2008. The best-fitting model based on the drinks per day data had four trajectories labeled as "Increasing Drinkers" (5.3% of sample), "Decreasing Drinkers" (5.9%), "Stable Drinkers" (24.2%), and "Non/Infrequent Drinkers" (64.6%). Using group assignments generated by the trajectory model, one adjusted logistic regression analysis contrasted the groups with low alcohol intake in 1998 (Increasing Drinkers and Non/Infrequent Drinkers). In this model, baseline education, physical activity, cigarette smoking, and binge drinking were significant factors. Another analysis compared the groups with higher intake in 1998 (Decreasing Drinkers versus Stable Drinkers). In this comparison, baseline depression, cigarette smoking, binge drinking, and retirement status were significant. Findings underscore the need to periodically counsel all older women on the risks and benefits of alcohol use.

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.

Acute renal failure in severe pancreatitis: A population-based study

INTRODUCTION

Acute pancreatitis (AP) is a common illness with varied mortality and morbidity. Patients with AP complicated with acute renal failure (ARF) have higher mortality than patients with AP alone. Although ARF has been proposed as a leading mortality cause for AP patients admitted to the ICU, few studies have directly analyzed the relationship between AP and ARF.

METHODS

We performed a retrospective study using the population-based database from the Taiwan National Health Insurance Research Database (NHIRD). In the period from 1 January 2005 to 31 December 2005, every patient with AP admitted to the ICU was included and assessed for the presence of ARF and mortality risk.

RESULTS

In year 2005, there were a total of 221,101 admissions to the ICU. There were 1,734 patients with AP, of which 261 (15.05%) patients also had a diagnosis of ARF. Compared to sepsis and other critical illness, patients with AP had a higher risk of having a diagnosis of ARF, and patients with both diagnoses had a higher mortality rate in the same ICU hospitalization.

CONCLUSION

AP is associated with a higher risk of ARF, and, when both conditions exist, a higher risk of mortality is present.

The psychological impact of heavy drinking among the elderly on their co-residents: the 10/66 group population based survey in the Dominican Republic

BACKGROUND

There is very limited literature on alcohol use among the elderly and little is known about the impact it has on family and caregivers, especially in low and middle income countries.

AIM

To estimate the independent effect of heavy alcohol use among the elderly on the psychological health of their co-residents.

METHODS

This is a secondary analysis using data from the comprehensive cross-sectional survey of the 10/66 dementia research group population-based research programme in the Dominican Republic. The characteristics of the elderly participants as well as the co-residents were described. The independent association of heavy drinking among the participants with psychological morbidity in their co-residents was estimated. Different models were generated to rule out potential mediating effects of disability and behavioural symptoms.

RESULTS

Prevalence of heavy alcohol use in the elderly in Dominican Republic was 10.6%. There was a statistically significant independent effect of heavy alcohol use by the elderly on their co-residents mental health (PR=1.47; 95% CI 1.07-2.01) which was not accounted by disability (Sobel-Goodman test, p=0.15). Severity of psychological and behavioural symptoms partially (29.1% of the total effect) explained this association (Sobel-Goodman mediation test, p=0.006).

CONCLUSIONS

Health services for the elderly in low and middle income countries will have to be configured around detection of alcohol problems among the elderly as well as offering appropriate support to their co-residents.
