title: Health, developmental, and nutritional status of adolescent alcohol and marijuana abusers.
abstract: The impact of alcohol and marijuana abuse on the physical health and nutritional status of adolescents has not been well documented. The health consequences of alcoholism and chemical abuse in adults may not relate to the pediatric population. Forty-nine adolescent boys (mean age 15.8 years) with varying degrees of alcohol and marijuana use by self-report were evaluated as to their general health, pubertal development and nutritional status using health and dietary history, physical examination, anthropometrics, and biochemical assays of liver function and tissue nutrients. Thirteen (27%) were alcohol and marijuana abusers, 20 (41%) marijuana abusers, and 16 (32%) nonusers. There were significant differences between alcohol and marijuana abusers and marijuana abusers compared to nonusers with respect to endorsing symptoms of nutritional deficiency (muscle weakness, bleeding gums, tiredness, etc) (P less than .001). There were no significant differences between subgroups in other nutritional measures except plasma zinc concentration which was low in marijuana abusers (mean 85 micrograms/dL). All adolescents reported consuming adequate nutrients, although alcohol and marijuana abusers reported eating more snack foods and less fruit, vegetables, and milk than other groups. There were no significant differences in hematologic status (complete blood cell count, transferrin, folate), liver function (gamma-glutamyltranspeptidase), or anthropometric and sexual maturational indices of growth. There were no chronic signs of chemical abuse by physical examinations. It appears that health and nutritional disability from chemical abuse in adolescents relates more to poor dietary habits and symptomatic deterioration in general health than to specific effects on growth or nutritional status. Studies with larger numbers of subjects need to document these findings.
