PURPOSE To study the age trend of family and peer influence on adolescent smoking behavior using a national sample. METHODS Adolescents (N = 6,900), ages 14 through 18 years, from the 1988-89 Teenage Attitudes and Practices Survey, were selected for analyses. Data collected included measures for smoking status of the adolescent and their family and peers.(More)
OBJECTIVE To assess the interaction between leisure-time physical activity (LTPA) and occupational activity (OA) on the prevalence of obesity. DESIGN Secondary data analysis of a population based cross-sectional US national sample (NHANES III). SUBJECTS A total of 4889 disease-free, currently employed adults over age 20 y. MEASUREMENTS Subjects body(More)
BACKGROUND The built environment in which a person lives and works is thought to have a strong influence on his or her level of physical activity. However, this belief is largely based on cross-sectional studies underlining the need for prospective studies using natural experiments. DESIGN This study adopted a quasi-experimental research design with(More)
PURPOSE To evaluate the ability of social-psychological risk factors to predict adolescent smoking behavior. METHODS Nonsmoking adolescents (n = 4032) who participated in the 1989 and 1993 Teenage Attitudes and Practices Surveys (TAPS I) were selected for analyses. Four multivariate logistic models were used to examine (a) adolescents' smoking initiation,(More)
BACKGROUND Despite overwhelming evidence of the health benefits of physical activity, most American youth are not meeting the 60 minutes per day recommendation for moderate- to vigorous-intensity physical activity (MVPA). Policy changes have the potential to bring about substantial increases in physical activity in youth, within school and community(More)
This study examined the association of depressive symptoms of adolescents and their smoking behavior. A national cohort sample of school adolescents (N = 5,855) who participated in the 1989 and 1993 Teenage Attitudes and Practices Survey was obtained. The information from this survey included measures of smoking behavior and a series of factors related to(More)
BACKGROUND Accelerometer-derived total activity count is a measure of total physical activity (PA) volume. The purpose of this study was to develop age- and gender-specific percentiles for daily total activity counts (TAC), minutes of moderate-to-vigorous physical activity (MVPA), and minutes of light physical activity (LPA) in U.S. adults. METHODS(More)
This study examined reaction time (RT), anticipation time (AT), and visual performance under the influence of blood alcohol concentration (BAC), using a repeated-measures design. Subjects (8 men and 8 women), 21 to 40 yr. of age, participated in both single- and double-dose sessions, in which they drank approximately 2.3 oz. and 4.6 oz. of 86-proof vodka,(More)
OBJECTIVE The purpose of this study was to assess the effects of moderate dose alcohol consumption on human metabolic and cardiovascular responses during submaximal exercise. METHOD Ten female subjects participated in two experimental conditions: (1) an alcohol session where the subjects ingested 0.625 g per kg body weight of 80-proof ethyl alcohol (0.25(More)
PURPOSE To compare the classic physiological variables linked to endurance performance (VO2max, %VO2max at lactate threshold (LT), and running economy (RE)) with peak treadmill velocity (PTV) as predictors of performance in a 16-km time trial. METHODS Seventeen healthy, well-trained distance runners (10 males and 7 females) underwent laboratory testing to(More)
