Weight control methods in high school wrestlers.

Severe weight control methods used by high school wrestlers have caused concern about these students' growth and athletic performance. There are minimal prevalence data on a few methods of weight control used by wrestlers and no information on the relationship to body fat measurements. Weight control methods and the percent body fat of wrestlers (n = 49) were compared to competitive squash players (n = 20) and noncompetitive jogging and fitness students (n = 38) at an independent secondary school. Wrestlers used dieting (p = 0.0002), binging (p = 0.026, vomiting (p = 0.046), sweating (p = 0.0001), and fluid restriction to less than 2 cups/day (p = 0.0014) significantly more often than controls (squash players and jogging/fitness students). There was no difference between the wrestlers' and controls' use of fasting (p = 0.5) or exercising (p = 0.1). Neither group reported using a diuretic or laxative during the sports seasons. Although the wrestlers' percent body fat was lower than controls (mean for wrestlers = 10.3 +/- 3.5%, mean for controls = 12.4 +/- 3.7%, p = 0.01), wrestlers perceived their mean ideal weight to be less than their present weight (wrestlers = -1.56 +/- 6.20 lb, controls = +1.92 +/- 9.49 lb, p = 0.03). The methods of weight control practiced could potentially impair an adolescent's growth and development as well as increase the risk of dehydration or electrolyte imbalance during competition.

The adolescent. Athletics and development.

An appreciation of adolescent growth and development is essential to the understanding of problems faced by the adolescent athlete. Early adolescence (ages 10-15 years) can be characterized as the body period. Physical growth is genetically determined and can be influenced by disease, injury, and nutrition. Early maturers are subject to adult expectations which may lead to either failure or excessive acclaim. Middle adolescence (ages 15-18 years) is the sexuality period, with special emphasis on gender identity. Friendships are critical, and athletics can be a focal point for showing love and affection without social fear. Late adolescence (ages 18-22 years) is the separation period. Young people with athletic skills leave home to face greater athletic and academic pressure and competition in college. Adjustment to this final adolescent period is achieved through learning to lose as well as win with grace and dignity.

Asymptomatic bacteriuria in adolescent girls: II. Screening methods.

Of 500 asymptomatic adolescent girls who were screened for bacteriuria by three methods-dipslide (Uricult), dipstrip (Microstix-3 reagent strips), and home nitrite test (Microstix-Nitrite reagent strips)-eight cases (1.6%) were detected: 6/8 by dipslide and dipstrip; 5/8 by nitrite testing. The false-positive-rate (greater than 10(4) colonies/ml) of the dipslide test was 6.4%, and the dipstrip test, 2.8%. A history of vaginal discharge was not associated with "contaminated" specimens. False-positive nitrite tests were reported by 0.6% of the patients who returned the postcards. Overall, 70.4% of the patients returned the postcards for the home nitrite test. The patients were divided by method of payment (Medicaid vs non-Medicaid) in order to provide an approximation of socioeconomic status; non-Medicaid patients were significantly more likely to return postcards than Medicaid patients (75.8% vs 63.7%). Of the group reporting previous urinary tract infection, 79% of both Medicaid and non-Medicaid patients returned postcards, suggesting that a prior experience with the diagnosis increased compliance with a home test.

Asymptomatic bacteriuria in adolescent girls: I. Epidemiology.

Because the incidence of bacteriuria in asymptomatic school girls is low (1% to 2%), we examined possible risk factors in adolescents, such as previous history of urinary tract infection (UTI) and sexual intercourse (previous and recent). Eight (1.6%) of 500 adolescent girls were detected with asymptomatic bacteriuria (ABU). Of 47 patients reporting a previous UTI, four (9%) were bacteriuric. Two other patients detected with bacteriuria had a history of enuresis; thus 6/8 adolescents with ABU had a history that suggests a need to screen for infection. A history of sexual activity was not helpful in case detection. Of the 500 girls, 133 had a routine pelvic examination at the time of the visit. The procedure was not associated with bacteriuria, as measured by a home nitrite test each day for three days following the clinic visit.
