Cross-sectional data on alcohol and marijuana use and sexual behavior among male and female secondary school students in New Providence, The Bahamas.

BACKGROUND: While The Bahamas have significantly reduced poor reproductive health outcomes among adolescents and emerging adults, data indicate that youth are engaged in sexual risk behaviors. Substance use has been linked to increased risk for HIV and sexually transmitted infections in other contexts. There are limited data on Bahamian youth in relation to consumption of alcohol and marijuana use and engagement in sexual behaviors. OBJECTIVE: This study aimed to assess potential relationships between alcohol and marijuana use and engagement in sexual behavior among government secondary school students in New Providence, The Bahamas. MATERIALS AND METHODS: Total sample size was 2572, and about 56% of respondents were female. Mean age was 14.2 (SD 2.7 years). Cross-sectional data came from a baseline survey conducted as part of a longitudinal randomized controlled evaluation of a school-based HIV prevention and reproductive health program in New Providence. RESULTS: Overall, 46.5% (519) males and 44.8% (652) females reported alcohol consumption; 7.3% (82) males and 1.7% (25) females reported use of marijuana in the last 6 months. About 43% (477) male respondents and 16% (231) female respondents reported ever having vaginal sex. Logistic regression analysis indicates that increased likelihood of engaging in sex during the past 6 months is associated with being older, male, and consuming alcohol and marijuana. CONCLUSION: These data provide a 'global correlation' between substance use and engagement in sexual behaviors among Bahamian adolescents. Longitudinal research is needed to assess event specific risks and identify mediating and moderating factors. These findings indicate the importance of integrating reproductive health and substance use education.

An observer-blinded study of 1% permethrin creme rinse with and without adjunctive combing in patients with head lice.

OBJECTIVES: To determine if NIX (Warner Lambert Healthcare, Morris Plains, NJ) 1% Permethrin Creme Rinse Lice Treatment (1% PLT) without combing will effectively treat >/=95% of patients on day 2 or on day 15; to determine whether combing influences efficacy. STUDY DESIGN: A randomized, observer-blinded study enrolled 95 infested adults and children. All patients were treated with 1% PLT on day 1 and, if still infested, on day 8. One third of households were randomized to the combing group and two thirds to the no-combing group. Efficacy was assessed by: (1) visual inspection on days 1, 2, 8, 9, and 15 and, (2) shampooing/straining on days 2, 9, and 15. The target efficacy was 95%. RESULTS: In the no-combing group, the lice-free rate was 83.1% on day 2 (95% CI, 71.0-91.6), 45.8% on day 8 (before second treatment) (95% CI, 32.7-59.2), 77.6% on day 9 (95% CI, 64.7-87.5), and 78.3% on day 15 (95% CI, 65.8-87.9). Adjunctive combing did not improve efficacy on any day. CONCLUSIONS: In this population, 1% PLT was significantly less than 95% effective and suggests resistance to 1% PLT. The failure of nit removal combing by nonprofessional caregivers to improve efficacy demonstrates the unreliability of combing as adjunctive treatment in this setting.
