    ABSTRACT: To test the feasibility, acceptability, and potential efficacy of after-school dance classes and a family-based intervention to reduce television viewing, thereby reducing weight gain, among African-American girls. Twelve-week, 2-arm parallel group, randomized controlled trial. Low-income neighborhoods. Sixty-one 8-10-year-old African-American girls and their parents/guardians. The treatment intervention consisted of after-school dance classes at 3 community centers, and a 5-lesson intervention, delivered in participants' homes, and designed to reduce television, videotape, and video game use. The active control intervention consisted of disseminating newsletters and delivering health education lectures. Implementation and process measures, body mass index, waist circumference, physical activity measured by accelerometry, self-reported media use, and meals eaten with TV. Recruitment and retention goals were exceeded. High rates of participation were achieved for assessments and intervention activities, except where transportation was lacking. All interventions received high satisfaction ratings. At follow up, girls in the treatment group, as compared to the control group, exhibited trends toward lower body mass index (adjusted difference = -.32 kg/m2, 95% confidence interval [CI] -.77, .12; Cohen's d = .38 standard deviation units) and waist circumference (adjusted difference = -.63 cm, 95% CI -1.92, .67; d = .25); increased after-school physical activity (adjusted difference = 55.1 counts/minute, 95% CI -115.6, 225.8; d = .21); and reduced television, videotape, and video game use (adjusted difference = -4.96 hours/week, 95% CI -11.41, 1.49; d = .40). The treatment group reported significantly reduced household television viewing (d = .73, P = .007) and fewer dinners eaten while watching TV (adjusted difference = -1.60 meals/week, 95% CI -2.99, -.21; d = .59; P = .03). Treatment group girls also reported less concern about weight (d = .60; P = .03), and a trend toward improved school grades (d = .51; P = .07). This study confirmed the feasibility, acceptability, and potential efficacy of using dance classes and a family-based intervention to reduce television viewing, thereby reducing weight gain, in African-American girls.

    ABSTRACT: To determine the effect of increasing the aerobic component of the school's physical activity program and improving the knowledge about weight control and blood pressure on the blood pressure and body fat of early adolescents. The subjects were 1140 youth aged 11 to 14 years (630 females, 510 males; 64% white, 24.4% African-American, and 11.6% "other"), who were randomly assigned by school into four treatment groups: exercise only, education only, exercise and education combined, and control group. Heights, weights, and skinfold thicknesses were measured, and body mass index (BMI) was computed kg/m(2). Blood pressure was obtained in duplicate using a random-zero mercury sphygmomanometer. Maximal oxygen uptake was predicted from a submaximal cycle ergometer test. Data were analyzed using analysis of covariance statistics, adjusting for gender, ethnicity, age, socioeconomic status, and initial baseline characteristics. Systolic and diastolic blood pressures increased more in the control group than in the intervention groups (p =.001). The BMI did not change significantly (p =.709), but the sum of skinfolds increased less in subjects in the exercise intervention groups than the education only or control groups (p =.0001). The small increase in (p)VO(2)max of the combined exercise and education group was significantly greater than the education only group (p =.0001). An exercise program for youth can have a positive effect on blood pressure independent of body weight loss.

    ABSTRACT: Physical activity in adolescence has been reported to enhance physical activity in adulthood, but detailed information on the enhancing effect of different types of adolescent sports is lacking. We evaluated the association between participation in different types of adolescent sports and physical activity in adulthood. The sample comprised 7794 males and females who responded to the mailed questions on physical activity status at age 14 years and at age 31 years in follow-up surveys of the Northern Finland 1966 birth cohort. The associations between adolescent participation in different sports and adult physical activity was examined by multinomial logistic regression. Frequent participation in sports after school hours in adolescence was associated with a high level of physical activity in adulthood. In males, adolescent participation in ball games, intensive endurance sports, track and field, and combat sports was associated with a high or very high level of adult activity. In females, the same applied to adolescent participation in running, orienteering, track and field, cycling, gymnastics, and riding. Adolescent participation in ball games increased participation in ball games in adulthood, especially in males, while participation in cross-country skiing, running, and orienteering provided the greatest stimulation to carry over of some endurance sport to adulthood. Participation in sports at least once a week among females and twice a week among males was associated with high level of physical activity in later life. Adolescent participation in the intensive endurance sports, and some sports that require and encourage diversified sports skills, appeared to be most beneficial with respect to the enhancement of adult physical activity.
