This study, a secondary analysis of the National Longitudinal Study of Adolescent Health, used a representative sample of 7th-through 12th-grade students enrolled in US public schools between April and December 1995. Data were collected in respondents' homes using trained interviewers. A subset of 4,485 adolescents aged 12-17 were surveyed with regard to alcohol-use practices and related health-risk behavior, interpersonal problems, and demographic characteristics. Results showed adolescent males as significantly more likely to drink at high risk than adolescent females. Among those who drank one or more times in the past year, older adolescents were significantly more likely to report high-risk drinking than younger adolescents. Significantly more high-risk adolescents reported having a hangover, vomiting, regretting a behavior, having trouble with parents, regretting a sexual activity, having dating problems, fighting, having trouble with friends, and experiencing school trouble than did low-risk adolescents. These findings underscore the long-range significance of a coordinated school health program; in particular, school health services, school health instruction, and school health environment. Implications for school-based and community-based prevention and intervention programs are presented.

The purpose of this study was to report the relationship among perceived intoxication, performance impairment, and actual blood alcohol concentration (BAC) levels. Fifteen subjects, aged 21 to 40, completed both single- and double-dose sessions of alcohol consumption. BACs, reaction and anticipation time, and perceived intoxication data were collected during both sessions. Analysis of data showed that perceived intoxication was significantly related to performance impairment, but the actual BAC was not.

A fundamental problem with classifying agriculturally related injury is that there is neither a rational nor a comprehensive scheme for grouping incidents into categories describing actual exposures encountered on farms and in agricultural work. Current surveillance systems are unable to differentiate between work that is related to farm production and work that is not, and to include all exposed persons in the surveillance. The proposed Farm and Agricultural Injury Classification Code is a step toward overcoming these problems. When it was applied to previously analyzed fatality data, 40% of cases previously identified as farm production work were reclassified into other categories.

This study examined proprioceptive responses under equivalent rising and falling blood alcohol concentrations (BAC), using a repeated-measures design. Seven volunteer subjects, 21 to 35 years of age, participated in the study. After alcohol consumption, BAC readings were obtained every 5 minutes, and the proprioceptive responses were measured at the following BAC levels (in %): 0 (baseline), rising 0.05, 0.075, 0.1, falling 0.075, and 0.05. The analysis focused on the comparisons of these measures at the equivalent rising and falling 0.05% and at the 0.075% BACs. Results showed that the proprioceptive response was less accurate during the rising than the falling BACs.
