Non-medical use of prescription drugs (NMUPD) by adolescents is a significant public health concern. The present study investigated the profile of NMUPD in 1349 adolescent offenders from the Pathways to Desistance project, and whether NMUPD predicted future delinquency using longitudinal data. Results indicated that increased frequency and recency of NMUPD in adolescent offenders are related to some demographic factors, as well as increased risk for violence exposure, mental health diagnoses, other drug use, and previous delinquency, suggesting that severity of NMUPD is important to consider. However, ANCOVA analyses found that NMUPD was not a significant predictor of drug-related, non-aggressive, or …

Examining Racial Differences In Sympathetic Activity Assessed During Recovery From Exercise In Obese Adolescent Females, Stacey Hall

Theses and Dissertations

Sympathetic overactivity (SO) is associated with obesity and cardiovascular disease (CVD) mortality. Black adolescents have an increased risk of obesity and CVD later in life, particularly females. PURPOSE: To evaluate differences in SO between black (BOA) and white obese female adolescents (WOA). METHODS: Sixty-one BOA (n=49, 13.7±1.6 yrs, 38.1±6.1 kg/m2) and WOA (n=12, 13.3±2.2 yrs, 34.3±4.9 kg/m2) completed a maximal graded treadmill test after which an exercise recovery index (ERI; heart rate/VO2 plateau) was calculated. RESULTS: The ERI was significantly greater in BOA compared to WOA (29.8 ± 6.4 vs. 24.1 ± 3.1, P = 0.004). Multiple linear regression modeling …

Examining The Behavioral And Molecular Aspects Of Adolescent Nicotine Dependence: Implications For Vulnerability To Drugs Of Abuse, Dena Heath Kota

Theses and Dissertations

Approximately 200 million men and 100 million women smoke worldwide. In the United States, an estimated 25.9 million men (23.9 percent) and 20.7 million women (18.1 percent) are smokers. The commencement of smoking at a young age is thought to increase addiction liability, decrease the probability of successful cessation, and correlate with a higher number of cigarettes smoked per day. Studies from the World Health Organization indicate that between 80,000 and 100,000 children start smoking every day worldwide. These statistics suggest that adolescence is a critical phase for developing nicotine dependence. The work in this dissertation contributes to the further …
