Problem drinking among Cambodian refugees in the United States: how big of a problem is it?

OBJECTIVE: The present study assesses current drinking behavior in a representative sample of Cambodian refugees. Earlier estimates of alcohol use in this population suggest that Cambodian refugees are at elevated risk for alcohol-use problems, but these studies have relied on convenience samples and may not reflect current consumption patterns. METHOD: A cross-sectional, face-to-face interview was conducted in Khmer on a household probability sample of Cambodian refugees residing in the largest such community in the United States. The overall response rate was 87% and yielded 490 respondents in the current analyses. RESULTS: Rates of consumption and alcohol-use problems were low in this population. Few participants (26%) reported any alcohol consumption in the 30 days preceding the interview, and only 2% reported any heavy drinking in the last 30 days. Multivariate analyses indicated that younger participants and men were more likely to report any recent drinking, and men were more likely to report any heavy drinking. Notably, recent consumption was not related to degree of trauma exposure or extent of psychiatric distress when controlling for age and gender. CONCLUSIONS: These data contrast dramatically with the widespread belief that Cambodian refugees are at elevated risk for problem drinking. Findings highlight the pitfalls of drawing population-based conclusions from data based on nonrepresentative samples or from nonstandard measures of alcohol consumption.

Drinking practices and neuropsychological test performance in sober male alcoholics and social drinkers.

The relationships between alcohol intake (per occasion over time) and performance on neuropsychological tests, as they might be affected by anxiety and depression, were investigated in both an alcoholic (N = 60) and social drinking (N = 43) sample. alcoholics, a Maximum Quantity Frequency (MQF) of alcohol consumed over the previous six months was found to be the best predictor of an impairment index. Neither anxiety nor depression were correlated with test performance. In social drinkers, anxiety was the best predictor of performance on the impairment index; depression was not predictive. Neither MQF nor a commonly used measure of drinking behaviors, weighted quantity per occasion (QPO), significantly predicted performance in the social drinkers once anxiety was accounted for. The results support the assumption that in alcoholics the greater and more frequent the alcohol ingestion, the more the brain's functioning is disrupted, at least as reflected in neuropsychological test performance. Anxiety appears to play a major role in the test performance of social drinkers and should be monitored in future studies in this research area.

Antecedents of drinking for early- and late-onset elderly alcohol abusers.

The present study compared antecedents to recent drinking for two groups of elderly alcohol abusers admitted for treatment. Twenty-three early-onset alcohol abusers were matched with 23 late-onset alcohol abusers according to age and sex. Depression, loneliness and lack of social support were the most frequently reported antecedents to preadmission drinking behavior for both groups. However, early-onset subjects were more likely to have changed residence, were intoxicated more often and experienced more severe levels of depression and anxiety. Late-onset subjects had greater life satisfaction and motivation for treatment, but were rated by collaterals as having more severe alcohol problems. Early-onset subjects were more likely to drop out of treatment. Treatment implications for age-related commonalities are discussed.

Progressive hypoglycemia's impact on driving simulation performance. Occurrence, awareness and correction.

OBJECTIVE: Progressive hypoglycemia leads to cognitive-motor and driving impairments. This study evaluated the blood glucose (BG) levels at which driving was impaired, impairment was detected, and corrective action was taken by subjects, along with the mechanisms underlying these three issues. RESEARCH DESIGN AND METHODS: There were 37 adults with type 1 diabetes who drove a simulator during continuous euglycemia and progressive hypoglycemia. During testing, driving performance, EEG, and corrective behaviors (drinking a soda or discontinuing driving) were continually monitored, and BG, symptom perception, and judgement concerning impairment were assessed every 5 min. Mean +/- SD euglycemia performance was used to quantify z scores for performance in three hypoglycemic ranges (4.0-3.4, 3.3-2.8, and <2.8 mmol/l). RESULTS: During all three hypoglycemic BG ranges, driving was significantly impaired, and subjects were aware of their impaired driving. However, corrective actions did not occur until BG was <2.8 mmol/l. Driving impairment was related to increased neurogenic symptoms and increased theta-wave activity. Awareness of impaired driving was associated with neuroglycopenic symptoms. increased beta-wave activity, and awareness of hypoglycemia. High beta and low theta activity and awareness of both hypoglycemia and the need to treat low BG influenced corrective behavior. CONCLUSIONS: Driving performance is significantly disrupted at relatively mild hypoglycemia, yet subjects demonstrated a hesitation to take corrective action. The longer treatment is delayed, the greater the neuroglycopenia (increased theta), which precludes corrective behaviors. Patients should treat themselves while driving as soon as low BG and/or impaired driving is suspected and should not begin driving when their BG is in the 5.0-4.0 mmol/l range without prophylactic treatment.

Public availability of distilled spirits: structural and reported consumption changes associated with liquor-by-the-drink.

The impact of the implementation of liquor-by-the-drink (LBD) in North Carolina on the availability of distilled spirits and on individual drinking behavior is evaluated. Distilled spirits outlet data show that the shift from brown-bagging to LBD resulted in a 250% increase in the number of places where liquor could be purchased, whereas the number of on-premise establishments where liquor could be consumed remained relatively constant. Most drinkers in both LBD and non-LBD counties purchase mixed beverages at least occasionally, and such consumption occurs only slightly less frequently than on-premise beer and wine consumption.

Self-reported drinking and alcohol-related problems among early adolescents: dimensionality and validity over 24 months.

OBJECTIVE: Researchers rely on adolescents' self-reports of alcohol consumption and alcohol-related problems, despite little evidence concerning their validity. We assessed the reliability and validity of adolescents' self-reports, employing collateral validation and focusing on the understudied transitional years of early adolescence. METHOD: Subjects were 214 boys and 247 girls who participated in school-wide surveys that assessed drinking, drunkenness and alcohol-related problems each year for 3 years. These measures were validated by collateral (peer) reports and by separate, 7-day drinking calenders. Internal consistency and test-retest reliability were also assessed. RESULTS: Results replicated findings with older adolescents that drinking/drunkenness and alcohol-related problems fall on two partially overlapping dimensions. Scales assessing each dimension had moderate to high internal consistency and high test-retest stability. Correlations with collateral reports were relatively strong for the drinking/drunkenness scale, moderate for a dichotomous variable reflecting the presence or absence of alcohol-related problems, and more modest for the alcohol-related problems scale. Correlations with diary reports of drinking behavior were strong for drinking/drunkenness. Results generally replicated across gender and over time. CONCLUSIONS: Researchers can have some confidence in the reliability and validity of early adolescents' survey self-reports, particularly of alcohol consumption (alcohol-related problems occurred with low base rates, perhaps limiting validity coefficients). Because drinking/drunkenness and alcohol-related problems shared 30% of their variance, factors other than consumption (e.g., personality factors) apparently influenced the experience of alcohol-related problems.

Outcome of nursing home care for residents with alcohol use disorders.

OBJECTIVES: To describe the outcome of nursing home (NH) care for a previously established cohort of residents with active, inactive or no alcohol use disorder (AUD), and to examine demographic variables, health services utilization, mortality and drinking behaviors in this group. DESIGN: Retrospective cohort study with participant interviews at NH admission and 3 years later. SETTING: Urban Veterans Affairs (VA) Medical Center and Nursing Home Care Unit (NHCU). PARTICIPANTS: Patients older than age 50 admitted consecutively to a VA NHCU between July 1991 and February 1993 who completed a structured interview, N = 117. MAIN OUTCOME MEASURES: AUD as determined by DSM-III-R criteria. Demographics, health services utilization and mortality as abstracted from the VA medical record. RESULTS: Health service utilization as measured by care episodes was not significantly different in the three groups (active, inactive and no AUD), but subjects with AUD had documented health services use related to alcoholism, including hospitalizations for alcohol-related illness, placements in long-term care facilities to control drinking and death from alcohol-related causes. The mean age at death was significantly younger for study participants with active or inactive AUD compared to those with no AUD: 67.7, 70.4 and 77.9 years, respectively (p < 0.004). Of the 21 participants with active AUD at NHCU entry, 11 resumed drinking after discharge and six still met criteria for active AUD 3 years later. CONCLUSIONS: The subset of NHCU patients with active AUD continued to incur alcohol-related hospitalizations and institutionalizations following NHCU discharge and suffered early mortality relative to their peers. Effective models of care for this subset of patients should be sought.

A method for third ventricular cannulation of small passerine birds.

This paper describes a method for chronically cannulating the third ventricle of the white-crowned sparrow, a small passerine bird, without damaging the midsagittal sinus. The method is reliable and chronic over at least 1 month. The technique was verified by assessing the effects of angiotensin II (ANG II) on inducing drinking behavior. All birds rapidly recovered from the surgery and tolerated repeated injections spaced over 1 month. Animals were injected with saline or 0.01, 0.5, 1.0, and 10.0 micrograms of ANG II, respectively. The intermediate dose of 1.0 microgram was maximally effective and caused a significant increase of water intake over the test hour. Lower and higher doses were less effective. This method for cannulating the third ventricle of small passerine birds should prove beneficial in future neurobiological applications.

On the role of ascending dopamine systems in the control of voluntary ethanol intake and ethanol intoxication.

Selective lesions of the ascending dopamine pathways were made by bilateral injection of the neurotoxin 6-OHDA (8 micrograms/4 microliters). Catecholamine fluorescence histochemistry revealed a marked degeneration of the ascending mesostriatal and mesolimbic dopamine systems, while the hypothalamic dopamine and noradrenaline nerve terminals were unaffected. After recovery of feeding and drinking behaviors the voluntary ethanol intake was not different from that of the controls. The time of ethanol-induced narcosis and the extent of ethanol-induced hypothermia were not affected. In contrast, in a tilting-plane test conducted two months after the operation, ethanol impaired the performance of the 6-OHDA-treated rats significantly less than that of the controls. This finding suggests a role for the ascending dopamine neurons to the forebrain in the intoxicating effect of ethanol.

Investigating Gender Convergence in Alcohol Consumption in Finland, Germany, The Netherlands, and Switzerland: A Repeated Survey Analysis.

Since the 1970s there has been concern that women may have started to adopt the drinking behaviors of men, a process seen as the result of emancipation in which women increasingly move into professions and/or lifestyles similar to those of men. This is called the convergence hypothesis. The present analysis investigated a possible closing of the gender gap and includes four countries that had national survey data for at least two time points: Finland (1984, 1992), Germany (1984, 1990), The Netherlands (1981, 1989), and Switzerland (1987, 1992). Significant convergence could be found only in Finland, which consisted of a greater increase of Finnish women becoming current drinkers and of a greater relative increase in the women's mean consumption. The fact that gender convergence was found only for Finland could be due not only to the longer observation period, but also to the egalitarian position of women and the changing drinking culture of the country.

Development of angiotensin-induced drinking in the rat.

The suckling rat responds from birth to intraventricular angiotensin, and the drinking behavior elicited by the hormone achieves adult characteristics of reliability and sensitivity at 4--5 days of age. Additional testing of 5-day-old rats injected with a range of doses showed that the threshold dose lies between 0.1--1.0 ng, which is comparable to the adult sensitivity to intraventricular injections. The hormone also increases milk intake in neonates, but the animals choose water over milk as early as 17 days.

Alcohol use in relation to driving records among injured bicyclists.

To prevent alcohol-related occupational mishaps, employers often conduct background checks on prospective employees for history of driving while intoxicated (DWI) and driving under the influence of alcohol (DUI) to screen out candidates with drinking problems. Few studies, however, have examined the pervasive nature of drinking behavior across activity domains. Based on trauma registry data, we constructed a historical cohort of 120 Maryland residents ages 18 years or older who were injured while riding a bicycle between 1990 and 1997. Driving records for the 120 bicyclists for the 3 years between May 6, 1995 and May 5, 1998 were obtained from the state motor vehicle administration and were analyzed in relation to BAC-positive status at the time of injury. Bicyclists with positive BACs at the time of admission to the trauma center were significantly more likely than those with negative BACs to have a record of license suspension/revocation (52% vs 14%, P < 0.01) and to have DWI/DUI convictions (30% vs 3%, P < 0.01). Despite the modest sample size, this study provides compelling evidence of the pervasive nature of risky drinking between bicycling and driving activities.

Behavioral risk factors for STD/HIV transmission in Bangladesh's trucking industry.

To examine behaviors that could influence STD/HIV transmission in Bangladesh's trucking industry, a survey was orally administered to 388 truck drivers/helpers at Tejgaon truck stand in Dhaka. A two-tiered sampling strategy was used: 38 trucking agencies were randomly selected and a mean of 10.2 subjects was recruited from each agency. Focus group and in-depth interviews were also conducted. The focus was on behaviors that affect (i) exposure to STD/HIV infection, (ii) efficiency of transmission of infection and (iii) duration of infectiousness. The findings illustrated that intravenous drug use was not an important risk factor; only 1 subject had used drugs intravenously. Sexual risk behaviors, however, were prevalent: the mean number of sexual partners in the past year was 4.57 (SD=8.70) and in the past 3 months was 1.82 (SD=3.27). Premarital and extramarital sex was common, often with commercial sex workers (CSW); 54% of all subjects had relations with at least 1 CSW in the past year. In a multiple logistic regression analysis, subjects who engaged in other types of socially risky behavior (drinking alcohol, ingesting or smoking recreational drugs, having sex with other men) were significantly (p<0.05) more likely to have had sex with a CSW in the past year. While 7.2% of subjects had a male sex partner in the past year, 21% had ever had one (likely youthful experimentation for most). Condom use was very infrequent: of the 343 subjects who had ever had sexual intercourse only 31% had ever used a condom and most of those subjects had used only once or occasionally. Having sex with CSWs, being married, having heard of AIDS and age were significantly associated (p<0.05) with ever use of condoms. Frequently, subjects who had genital symptoms either did not have those symptoms treated at all or treated in a timely fashion, and over 1/3 did not change their sexual behavior while infected. To reduce the potential for the spread of STD/HIV in this population, appropriate treatment practices for sexually transmitted infections need to be encouraged and condom use promoted, particularly in the context of casual sexual relations.

Circadian rhythms in vasopressin deficient rats.

Circadian rhythms in wheel running and drinking behavior were investigated using heterozygous an homozygous (diabetes insipidus) female Brattleboro rats Despite the lack of vasopressin in the suprachiasmatic nuclei of the diabetic rats, they showed coherent rhythms, both in cyclic light and in constant light. However, the periods of the free-running rhythms were longer for the diabetic rats, they were less active, and, of course, were severely polydipsic. Replacement treatment with systemic infusions of vasopressin reversed the polydipsia but did not affect the other measures.

Dissociation of ethanol and saccharin preference in sP and sNP rats.

BACKGROUND: It has been proposed that ethanol intake and consumption of sweet tasting solutions are positively correlated in rodents. Experiment 1 of the present study investigated whether selectively bred ethanol-preferring (sP) and -nonpreferring (sNP) rats differed, consistently with the above hypothesis, as to saccharin intake and preference. Experiment 2 evaluated whether saccharin addition to the ethanol solution, likely resulting in a highly palatable fluid, would result in an increase in voluntary ethanol intake in sP rats. METHODS: The saccharin solution was offered, in free choice with water, at a fixed concentration of 1 g/liter for 6 consecutive days in Experiment 1A or at ascending concentrations (0.002 to 16.4 g/liter, doubling the concentration every day) in Experiment 1B. In Experiment 2, 1 g/liter saccharin was added to the standard 10% ethanol solution and offered to sP rats in free choice with water for 7 consecutive days. RESULTS: In both Experiments 1A and 1B, sP and sNP rats showed avidity for the saccharin solution with marginal line difference in saccharin intake and preference. In Experiment 2, daily ethanol intake remained stable at baseline levels (6-7 g/kg), irrespective of the saccharin addition to the ethanol solution. CONCLUSIONS: The results of Experiments 1A and 1B suggest that saccharin drinking behavior in sNP rats deviates from the hypothesis that saccharin and ethanol intakes may co-vary; thus, at least in sNP rats, saccharin and ethanol intakes do not appear to be influenced by the same genetic factors. The results of Experiment 2 provide further support to the existence of a central set-point mechanism that regulates daily ethanol intake in sP rats, likely based on the pharmacological effects of ethanol.

Alcohol and environmental justice: the density of liquor stores and bars in urban neighborhoods in the United States.

OBJECTIVE: This study had two purposes: (1) to characterize the density of liquor stores and bars that individuals face according to race, economic status, and age in the urban United States and (2) to assess alternative measures of retailer density based on the road network and population. METHOD: We used census data on business counts and sociodemographic characteristics to compute the densities facing individuals in 9,361 urban zip codes. RESULTS: Blacks face higher densities of liquor stores than do whites. The density of liquor stores is greater among nonwhites in lower-income areas than among whites in lower- and higher-income areas and nonwhites in higher-income areas. Nonwhite youths face higher densities of liquor stores than white youths. The density of liquor stores and bars is lower in higher-income areas, especially for nonwhites. CONCLUSIONS: Mismatches between alcohol demand and the supply of liquor stores within urban neighborhoods constitute an environmental injustice for minorities and lower-income persons, with potential adverse consequences for drinking behavior and other social ills. Our results for bars are sensitive to the measure of outlet density as well as population density. Although neither measure is clearly superior, a measure that accounts for roadway miles may reflect proximity to alcohol retailers and thus serve as a useful refinement to the per-capita measure. If so, alcohol policy might also focus on density per roadway mile. Further research on the existence, causes, and consequences of environmental injustice in alcohol retailing is warranted.

Association of high density lipoprotein with whole blood-associated acetaldehyde levels.

We hypothesized that while moderate drinking is associated with increasing levels of high density lipoprotein (HDL) levels, excessive drinking of ethanol might, in fact, be associated with lower HDL levels and by implication increased cardiovascular risk. We therefore performed analyses of whole blood-associated acetaldehyde (WBAA) as a measure of drinking behavior and HDL on blood samples from 2780 individuals applying for life insurance. Whole blood-associated acetaldehyde correlated positively with HDL in the entire sample set throughout the range of values (R = 0.101, p = 0.0001). The relationship held for females (N = 477, p = 0.036) but was stronger for males (N = 2277, p = 0.0001). We conclude that ethanol consumption correlates positively with HDL for both males and females and that the relationship persists through higher ranges of ethanol consumption.

Alcohol use in high school: predicting students' alcohol use and alcohol problems in four-year colleges.

This research examined the effect of students' drinking behaviors in high school on their alcohol use and alcohol problems in college. Five colleges in New York State were randomly selected for the study. The telephone interview method was employed to survey college students during the spring semester of 1998. Within each participating college, students were randomly selected through the use of complete student telephone directories provided by the college administration. A total of 813 students were interviewed. Alcohol problems were measured with items from DSM-IV. Results indicate that both frequency and quantity of alcohol use in high school significantly affect students' alcohol consumption in college. Furthermore, the impact of alcohol use in high school on alcohol problems in college tends to be composed of a moderate direct effect and a relatively strong indirect effect via its impact on current alcohol consumption in college. Prevention efforts for drinking in college may need to start in high school to reduce or delay alcohol use by high school students. Additional assessment services and more readily available treatment services may be required to address potential alcohol problems among college students. Future research should examine the effect and longevity of students' alcohol problem symptoms after they graduate from college.
