Claims that juvenile delinquency may be associated with reactive hypoglycemia or nutritional deficiencies have received widespread attention but little objective evaluation. To assess the validity of these claims, nutritional and psychological indices of juvenile delinquents have been measured. Serum glucose and insulin profiles during an oral sucrose tolerance test were measured in 137 delinquent and 41 nondelinquent male adolescents aged 14 to 19. In addition, nutritional status of both populations was assessed by anthropometry (height, weight, arm circumference, triceps skin fold) and biochemical measures (hematocrit, red-blood cell thiamin, and serum copper, ferritin, and zinc). Delinquent subjects had slightly but significantly lower serum glucose values at four of six time points (fasting, 60 minutes, 120 minutes, 180 minutes) and higher serum insulin values at one time point (30 minutes) compared with nondelinquent subjects. Changes in glucose from fasting levels indicate that these subjects were regulating serum glucose adequately, but doing so at lower values; changes in insulin from fasting levels indicate that black delinquents initially secreted more insulin than either white subject group. There were no significant associations between excursions in serum glucose or insulin and any adrenergic signs or symptoms of low blood glucose levels. Nutritional status of incarcerated delinquents did not differ from that of nonincarcerated subjects on most measures. Although the significantly lower serum glucose levels and higher serum insulin levels are intriguing, no support is offered by results of this study for allegations that sucrose ingestion causes reactive hypoglycemia in juvenile delinquents or that delinquent male adolescents are at greater risk nutritionally than male adolescents of the same age who are not delinquent.(ABSTRACT TRUNCATED AT 250 WORDS)

Attention-deficit-hyperactivity disorder (ADHD) is a common neuropsychiatric disorder that impairs social, academic, and occupational functioning in children, adolescents, and adults. In patients with ADHD, neurobiologic research has shown a lack of connectivity in key brain regions, inhibitory control deficits, delayed brain maturation, and noradrenergic and dopaminergic dysfunction in multiple brain regions. The prevalence of this disorder in the United States is 6-9% in youth (i.e., children and adolescents) and 3-5% in adults. Prevalence rates for youth are similar worldwide. Children with ADHD are at greater risk than children without ADHD for substance abuse and delinquency whether or not they receive drug therapy; however, early treatment with psychoeducation as well as drug therapy and/or behavioral intervention may decrease negative outcomes of ADHD, including the rate of conduct disorder and adult antisocial personality disorder. Drug therapy is effective for all age groups, even preschoolers, and for late-onset ADHD in adults. Stimulants, such as methylphenidate and amphetamine, are the most effective therapy and have a good safety profile; although recent concerns of sudden unexplained death, psychiatric adverse effects, and growth effects have prompted the introduction of other therapies. Atomoxetine, a nonstimulant, has no abuse potential, causes less insomnia than stimulants, and poses minimal risk of growth effects. Other drug options include clonidine and guanfacine, but both can cause bradycardia and sedation. Polyunsaturated fatty acids (fish oil), acetyl-L-carnitine, and iron supplements (for youth with low ferritin levels) show promise in improving ADHD symptoms. As long-term studies show that at least 50% of youth are nonadherent with their drug therapy as prescribed over a 1-year period, long-acting formulations (administered once/day) may improve adherence. Comorbid conditions are common in patients with ADHD, but this patient population can be treated effectively with individualized treatment regimens of stimulants, atomoxetine, or bupropion, along with close monitoring.
