RESUMEN
The authors determined whether lifetime prescription drug misuse (PDM) associated with increased risks for alcohol-related problems among 18- to 34-year-old, NESARC respondents. Among 8222 "ever-drinkers," 15.4% reported ever "misusing sedatives, tranquilizers, painkillers or stimulants ... as prescriptions or from indirect sources." Outcomes were within two alcohol-related problem domains, "risk-taking behaviors," including driving while drinking, fights, injuries, and arrests, and "interpersonal troubles," including problems with jobs, family, or friends. Among all drinkers and among alcohol-dependent and cannabis-using subsamples, those reporting PDM were significantly more likely to report alcohol-related "risk-taking behaviors" or "interpersonal troubles" than were those without PDM. In adjusted analysis, young age drinking onsets, and heavy and dependent drinking independently increased these risks. Results of this cross-sectional analysis support the need for longitudinal data to more clearly define the association between drinking problems and PDM, and which can support prevention, treatment, and harm-reduction efforts for younger, multisubstance users.

OBJECTIVE: This analysis tested whether comprehensive community interventions that focus on reducing alcohol availability and increasing substance abuse treatment can reduce alcohol related fatal traffic crashes. INTERVENTION: Five of 14 communities awarded Fighting Back grants by The Robert Wood Johnson Foundation to reduce substance abuse and related problems attempted to reduce availability of alcohol and expand substance abuse treatment programs (FBAT communities). Program implementation began on 1 January 1992. DESIGN: A quasi-experimental design matched each program community to two or three other communities of similar demographic composition in the same state. MAIN OUTCOME MEASURES: The ratio of fatal crashes involving a driver or pedestrian with a blood alcohol concentration of 0.01% or higher, 0.08% or higher, or 0.15% or higher were examined relative to fatal crashes where no alcohol was involved for 10 years preceding and 10 years following program initiation. RESULTS: Relative to their comparison communities, the five FBAT communities experienced significant declines of 22% in alcohol related fatal crashes at 0.01% BAC or higher, 20% at 0.08% or higher, and 17% at 0.15% or higher relative to fatal crashes not involving alcohol. CONCLUSIONS: Community interventions to reduce alcohol availability and increase substance abuse treatment can reduce alcohol related fatal traffic crashes.

OBJECTIVE: To explore whether people who start drinking at an early age are more likely to have been in physical fights after drinking, independent of respondent history of alcohol dependence and frequency of heavy drinking. DESIGN: In 1992, the US Census Bureau interviewed, in person, 42 862 randomly selected adults age 18 or older, mean age 44, household response rate 91.9%, and in-person response rate 97.4%. The survey included questions regarding the age respondents started drinking, frequency of heavy drinking, and whether respondents were ever or in the past year in a physical fight after drinking alcohol. RESULTS: Relative to respondents who did not begin drinking until age 21 or older, those who started drinking before age 17 were 2.9 to 4.1 times more likely ever in their lives, and at least 3 times more likely in the past year, to have been in a fight after drinking. These relationships were found even after controlling for personal history of alcohol dependence, years of drinking, frequency of heavy drinking, smoking, drug use, and other personal characteristics associated with the age respondents started drinking. CONCLUSIONS: An early age of drinking onset was associated with alcohol-related violence not only among persons under age 21 but among adults as well. Physicians need to query adolescent patients about the age they began drinking and counsel them about the increased risks associated with early drinking onset, such as an increased risk of being involved in alcohol-related violence.

OBJECTIVES: This study evaluated the impact of Rhode Island's legislation requiring children younger than 6 years to sit in the rear of motor vehicles. METHODS: Roadside observations were conducted in Rhode Island and Massachusetts in 1997 and 1998. Multivariate regression was used to evaluate the proportion of vehicles carrying a child in the front seat. RESULTS: Data were collected on 3226 vehicles carrying at least 1 child. In 1998, Rhode Island vehicles were less likely to have a child in the front seat than in 1997 (odds ratio = 0.6; 95% confidence interval = 0.5, 0.7), whereas no significant changes in child passenger seating behavior occurred in Massachusetts during that period. CONCLUSIONS: Rhode Island's legislation seems to have promoted safer child passenger seating behavior.

CONTEXT: In 1997, unintentional injury was the leading cause of death for persons aged 1 to 34 years. Approximately one third of deaths due to unintentional injury in the United States are estimated to be alcohol related. Onset of drinking at an early age has been found to be associated with alcohol dependence, but whether early-onset drinking increases risk for unintentional injury while drinking is unknown. OBJECTIVE: To explore whether persons who started drinking at an early age are more likely to have experienced unintentional injuries while under the influence of alcohol. DESIGN AND SETTING: The National Longitudinal Alcohol Epidemiology Survey, a cross-sectional survey conducted in 1992 of a representative sample of the US population. PARTICIPANTS: A total of 42,862 randomly selected adults (response rate, 90%; mean age, 44 years). MAIN OUTCOME MEASURES: Unintentional injury involvement while under the influence of alcohol by age of drinking onset (categorized as <14 years, each age from 14-20 years, or >/=21 years). RESULTS: Relative to respondents who began drinking at age 21 years or older, those who started before age 14 years as well as those who started at each intervening age up to 21 years were significantly more likely to have been injured while under the influence of alcohol, even after controlling for history of alcohol dependence, heavy drinking frequency during the period that they drank most, family history of alcoholism, and other characteristics associated with earlier onset of drinking. After adjusting for these variables, odds ratios for having been injured while under the influence of alcohol were as follows: for younger than 14 years, 2.98 (95% confidence interval [CI], 2.29-3.89); age 14 years, 2.96 (95% CI, 2.26-3.88); age 15 years, 3.14 (95% CI, 2.48-3.97); age 16 years, 2.38 (95% CI, 1.90-2.98); age 17 years, 2.12 (95% CI, 1.66-2.71); age 18 years, 1. 33 (95% CI, 1.08-1.64); age 19 years, 1.42 (95% CI, 1.07-1.89); and age 20 years, 1.39 (95% CI, 1.01-1.91). CONCLUSION: Drinking onset at ages younger than 21 years is associated with having experienced alcohol-related injuries. JAMA. 2000;284:1527-1533

OBJECTIVES: This study assessed whether states that lowered legal blood alcohol limits from 0.10% to 0.08% in 1993 and 1994 experienced post-law reductions in alcohol related fatal crashes. METHODS: Six states that adopted 0.08% as the legal blood alcohol limit in 1993 and 1994 were paired with six nearby states that retained a 0.10% legal standard. Within each pair, comparisons were made for the maximum equal available number of pre-law and post-law years. RESULTS: States adopting 0.08% laws experienced a 6% greater post-law decline in the proportion of drivers in fatal crashes with blood alcohol levels at 0.10% or higher and a 5% greater decline in the proportion of fatal crashes that were alcohol related at 0.10% or higher. CONCLUSIONS: If all states adopted the 0.08% legal blood alcohol level, 400-500 fewer traffic fatalities would occur annually.

Although moderate drinking does not necessarily increase a person's blood alcohol concentration (BAC) to the level at which driving is legally prohibited in the United States, any drinking can impair driving tasks. In addition to laws establishing lower legal BAC limits for drivers, legislative approaches for reducing alcohol-impaired driving include imposing sanctions for drinking and driving and restricting alcohol's availability.

OBJECTIVE: To determine whether a Maine law lowering the legal blood alcohol limit (BAL) from 0.10% to 0.05% for people convicted of driving while intoxicated (DWI) reduced the involvement of this group in fatal crashes. METHODS: The authors calculated changes in the proportions of fatal crashes involving drivers with prior DWI convictions from the six-year period before enactment of the law to the six-year period following enactment of the law, comparing Maine with the other New England states. RESULTS: In Maine, the proportion of fetal crashes involving drivers with recorded prior DWI convictions declined 25% following passage of the 0.05% DWI law, while the proportion rose in the rest of New England during the same years. The proportion of fatal crashes involving drivers with recorded prior DWI convictions and illegal alcohol levels also declined significantly in Maine, as did the proportion of fatal crashes involving fatally injured drivers with recorded prior DWI convictions and illegal alcohol levels. Most of the latter decline was due to a decline in alcohol-related fatalities of previously convicted drivers with very high BALs, of 0.15% or higher, at the time of the fatal crash. Each of these declines in Maine was significant relative to the rest of New England. CONCLUSION: Other states should consider instituting 0.05% BAL limits for convicted DWI offenders.

The purpose of this review is to update research on the prevention of alcohol-related traffic deaths since the 1988 Surgeon General's Workshop on Drunk Driving. Four primary areas of research are reviewed here: (a) general deterrence policies, (b) alcohol control policies, (c) mass communications campaigns, including advertising restrictions, and (d) community traffic safety programs. Modern efforts to combat drunk driving in the United States began with specific deterrence strategies to punish convicted drunk drivers, and then evolved to include general deterrence strategies that were targeted to the population as a whole. Efforts next expanded to include the alcohol side of the problem, with measures installed to decrease underage drinking and excessive alcohol consumption. In the next several years, greater efforts are needed on all these fronts. Also needed, however, are programs that integrate drunk driving prevention with other traffic safety initiatives.

The objective of this study was to evaluate the relation between drinking, drug use, and unprotected anal intercourse in young men who have sex with men. A cross-sectional analysis of first-visit data from a prospective cohort of 508 young gay men recruited from 1993 through 1994 from bars, college campuses, and the Fenway Community Health Center in Boston was performed. The major outcome measures were any unprotected anal intercourse, after drinking and when sober, stratified by type of sexual partner (steady or nonsteady) during the previous 6 months and during the most recent sexual encounter. The average age of the cohort was 23.3 years; 77.6% were white, and 76.4% were in college. These young men had a median of 10.5 male sexual partners in their lifetimes, and 3 sexual partners in the previous 6 months before enrollment. One hundred and thirty-four (26%) reported unprotected anal intercourse during the previous 6 months. Individuals who had unprotected anal intercourse were more likely to have a drinking problem (odds ratio [OR] = 1.95; 95% confidence interval [CI] = 1.26-3.01) and drank more (20.4 ml/day versus 13.9 ml/day; p < or = 0.01), compared with individuals who did not engage in unprotected anal intercourse. Overall, men were significantly less likely to have unprotected anal intercourse after alcohol or drug use, based on a series of paired analysis (OR = 0.27; 95% CI = 0.15-0.48). However, when we stratified by type of sexual partner, men were significantly more likely to have unprotected anal intercourse with their nonsteady sexual partners after drinking than when sober (OR = 4.33; 95% CI = 1.37-13.7), but were significantly less likely to have unprotected anal intercourse with steady partners (OR = 0.27; 95% CI = 0.15-0.48). The patterns observed as already mentioned for drinking were also found for substance use in general. Men who were more likely to have unprotected anal intercourse after substance use were significantly more likely to have a drinking problem (OR = 7.65; 95% CI = 2.34-24.59). These results suggest that the role of alcohol and unsafe sex in young gay men is complex, with the role of situational factors of paramount importance. Alcohol and substance use interventions designed to reduce HIV risk need to specify the role of substance use in the sexual context to be successful.

BACKGROUND: Human immunodeficiency virus (HIV)-infected individuals' initial presentation to medical care frequently occurs at a point of advanced immunosuppression. OBJECTIVES: To investigate the time between HIV testing and presentation to primary care. Also to examine factors associated with delayed presentation. METHODS: One hundred eighty-nine consecutive outpatients without prior primary care for HIV infection were assessed at 2 urban hospitals: Boston City Hospital, Boston, Mass, and Rhode Island Hospital, Providence. Sociodemographics, alcohol and drug use, social support, sexual beliefs and practices, and HIV testing issues were examined in bivariate and multivariate analyses for association with delay in presentation to primary care after positive test results for HIV. RESULTS: Of 189 patients, 74 (39%) delayed seeking primary care for more than 1 year, 61 (32%) delayed for more than 2 years, and 35 (18%) for more than 5 years after an initial positive HIV serologic evaluation. The median CD4+ cell count of subjects was 0.28 x 10(9)/L (range, 0.001-1.71 x 10(9)/L). In multiple linear regression analysis the following characteristics were found to be associated with delayed presentation to primary care after HIV testing: history of injection drug use (P<.001); not having a living mother (P=.01); not having a spouse or partner (P=.08); not being aware of HIV risk before testing (P<.001); and being notified of HIV status by mail or telephone (P=.002). An interaction effect between sex and screening for alcohol abuse was significant (P=.03) and suggested longer delays for men with positive screening test results (CAGE [an alcoholism screening questionnaire containing 4 structured questions], 2+) compared with men without positive screening test results or women. CONCLUSIONS: Patients with positive HIV test results often delay for more than a year before establishing primary medical care. Information readily available at the time of HIV testing concerning substance abuse, social support, and awareness of personal HIV risk status is useful in identifying patients who are at high risk of not linking with primary care. Patients who were notified of their HIV status by mail or telephone delayed considerably longer than those notified in person. Efforts to ensure primary care linkage at the time of notification of positive HIV serostatus are necessary to maximize benefits for both individual and public health and should be an explicit task of posttest counseling.

OBJECTIVE: To determine factors associated with disclosure of human immunodeficiency virus (HIV)-positive status to sexual partners. METHODS: We interviewed 203 consecutive patients presenting for primary care for HIV at 2 urban hospitals. One hundred twenty-nine reported having sexual partners during the previous 6 months. The primary outcome of interest was whether patients had told all the sexual partners they had been with over the past 6 months that they were HIV positive. We analyzed the relationships between sociodemographic, alcohol and drug use, social support, sexual practice, and clinical variables; and whether patients had told their partners that they were HIV positive was analyzed by using multiple logistic regression. RESULTS: Study patients were black (46%), Latino (23%), white (27%), and the majority were men (69%). Regarding risk of transmission, 41% were injection drug users, 20% were homosexual or bisexual men, and 39% were heterosexually infected. Sixty percent had disclosed their HIV status to all sexual partners. Of the 40% who had not disclosed, half had not disclosed to their one and only partner. Among patients who did not disclose, 57% used condoms less than all the time. In multiple logistic regression analysis, the odds that an individual with 1 sexual partner disclosed was 3.2 times the odds that a person with multiple sexual partners disclosed. The odds that an individual with high spousal support disclosed was 2.8 times the odds of individuals without high support, and the odds that whites or Latinos disclosed was 3.1 times the odds that blacks disclosed. CONCLUSIONS: Many HIV-infected individuals do not disclose their status to sexual partners. Nondisclosers are not more likely to regularly use condoms than disclosers. Sexual partners of HIV-infected persons continue to be at risk for HIV transmission.

OBJECTIVE: To assess sexually active adolescents' knowledge, attitudes, and behaviors associated with human immunodeficiency virus (HIV) testing and to determine the factors important in their decision to obtain voluntary HIV testing. DESIGN: Anonymous, random, digit-dial telephone survey undertaken in 1993. SETTING: Massachusetts households. PARTICIPANTS: Adolescents, 16 to 19 years of age. RESULTS: Of the 567 adolescents surveyed who had sexual intercourse within the past year, 127 (22%) had received HIV testing, with 54 (10%) stating that this testing was for personal reasons. A "great deal" or "some" worry about getting HIV/acquired immunodeficiency syndrome (AIDS) was expressed by 51%, and 56% felt that it was at least a little likely that they will get AIDS. Misconceptions were common about aspects of HIV testing: 35% did not believe or did not know that the HIV test results were kept in confidence, 19% thought that AIDS testers informed partners if the results were positive, and 30% did not think that the HIV test was very accurate. Although 92% (452/490) had seen a physician in the past year, only 30% (136/452) had ever discussed AIDS with a doctor. Multivariable analysis identified five factors as independently associated with voluntary adolescent HIV testing: 1) having had more than one sexual partner within the past year [odds ratio (OR): 2.9; 95% confidence interval (CI): 1.5, 5.5]; 2) believing that condoms are only somewhat effective at preventing the spread of AIDS (OR: 2. 6; 95% CI: 1.4, 4.8); 3) having discussed AIDS with a doctor (OR: 2. 6; 95% CI: 1.4, 4.8); 4) not having had a teacher discuss AIDS (OR: 2.2; 95% CI: 1.2, 4.2); and 5) believing that a positive test result means one has AIDS as opposed to carrying the virus (OR: 2.0; 95% CI: 1.1, 3.7). High-risk behavior of infrequent condom use and a history of a sexually transmitted disease were not significantly associated with voluntary HIV testing. CONCLUSION: Among sexually active Massachusetts adolescents, voluntary HIV testing is uncommon. Teens who have had multiple sexual partners and who do not believe condoms are effective in preventing transmission were most likely to have been tested. Issues requiring clearer communication to patients include the testing process, its availability, and confidentiality. Physicians can play an influential role in the promotion of HIV testing by discussing HIV risk behaviors with patients and offering those at risk voluntary HIV counseling and testing.

OBJECTIVES: This study assessed current levels of sunbathing and sunscreen use in the United States. METHODS: From a general-population telephone survey of aquatic activities among adults in 3042 US households, we examined responses by the 2459 Whites. RESULTS: Most adults (59%) reported sunbathing during the past year, and 25% reported frequent sunbathing. Of the subsample who reported sunbathing during the month before the interview, 47% routinely used sunscreen. Of these individuals, almost half did not use sunscreens with a solar protection factor of 15 or higher. CONCLUSIONS: About a quarter of US White adults report frequent sunbathing, and only about a quarter of sunbathers use sunscreens at recommended levels. These results should help focus future sun protection educational efforts.

OBJECTIVES: To estimate the prevalence of and identify risk factors for human immunodeficiency virus type 1 (HIV-1) and hepatitis B virus (HBV) infections and unprotected anal intercourse among young homosexual and bisexual men. METHODS: The authors performed a cross-sectional analysis of data from a prospective cohort of 508 young gay and bisexual men ages 18-29. RESULTS: HIV-1 seroprevalence was 2.4%, with five (1.3%) of 390 college students and seven (6.0%) of 117 non-students infected. After adjusting for confounders, HIV-1 infection was associated with having a history of a sexually transmitted disease other than HIV-1 or hepatitis B. The prevalence of hepatitis B markers in unvaccinated men was 12.9%. The presence of hepatitis B markers in unvaccinated men was significantly associated with Asian ethnicity, off-campus residence, and history of a sexually transmitted disease other than HIV-1 or hepatitis B and inversely associated with recent non-intravenous drug use. Eighteen percent of the participants reported having had sex with women during the previous 12 months, and 26.4% reported a history of unprotected anal intercourse during the previous six months. Men who reported unprotected anal intercourse were more likely to have at least one steady partner, to have met their partners in anonymous settings, and to be identified as probably alcohol dependent. CONCLUSIONS: Although the prevalence of HIV-1 infection among young homosexual and bisexual men in Boston was relatively low, the high rates of unprotected anal intercourse suggest a potential for future HIV-1 and hepatitis B transmission. Interventions should focus on young men with histories of sexually transmitted diseases, alcohol abuse, and depression.

OBJECTIVES: This study was undertaken to determine whether reductions in alcohol-related fatal crashes following adoption of 0.08% legal blood alcohol limits were independent of general regional trends. METHODS: The first five states that lowered legal blood alcohol limits to 0.08% were paired with five nearby states that retained a 0.10% legal standard. Within each pair, comparisons were made for the maximum equal available number of pre- and postlaw years. RESULTS: States adopting 0.08% laws experienced 16% and 18% relative postlaw declines in the proportions of fatal crashes involving fatally injured drivers whose blood alcohol levels were 0.08% or higher and 0.15% or higher. CONCLUSIONS: It all states adopted 0.08% legal blood alcohol limits, at least 500 to 600 fewer fatal crashes would occur annually.

OBJECTIVES: The purpose of this study ws to assess whether a community program begun in March 1988 that organized multiple city departments and private citizens could reduce alcohol-impaired driving, related driving risks, and traffic deaths and injuries. METHODS: Trends in fatal crashes and injuries per 100 crashes were compared in Saving Lives Program cities and the rest of Massachusetts from March 1984 through February 1993. In annual roadside surveys conducted at randomly selected locations, safety belt use among occupants of 54577 vehicles and travel speeds of 118442 vehicles were observed. Four statewide telephone surveys (n = 15188) monitored self-reported driving after drinking. RESULTS: In program cities relative to the rest of Massachusetts during the 5 program years in comparison with the previous 5 years, fatal crashes declined 25%, from 178 to 120, and fatal crashes involving alcohol decreased 42%, from 69 to 36. Visible injuries per 100 crashes declined 5%, from 21.1 to 16.6. The proportions of vehicles observed speeding and teenagers who drove after drinking were cut in half. CONCLUSIONS: Interventions organized by multiple city departments and private citizens can reduce driving after drinking, related driving risks, and traffic deaths and injuries.

Men have higher drowning rates than women for most age groups. Data from a 1991 national household survey (n = 3042) on aquatic activities were used to examine hypotheses about differential drowning rates by sex. Men and women were compared by (1) exposure to aquatic environments; (2) frequency of aquatic activities involving or potentially involving, submersion; (3) swimming training and ability; (4) aquatic risk-taking behaviors; and (5) alcohol use on or near the water. Men had elevated risks for exposure, risk taking, and alcohol use. It was concluded that several factors contribute to their relatively high drowning rates, including a possible interaction between overestimation of abilities and heavy alcohol use.
