Racial/ethnic and educational differences in the estimated odds of recent nitrite use among adult household residents in the United States: an illustration of matching and conditional logistic regression

A community prevention model to prevent children from inhaling and ingesting harmful legal products

Children's misuse of harmful legal products (HLPs), including inhaling or ingesting everyday household products, prescription drugs, and over-the-counter drugs, constitutes a serious health problem for American society. This article presents a community prevention model (CPM) focusing on this problem among pre and early adolescents. The model, consisting of a community mobilization strategy and environmental strategies targeting homes, schools, and retail outlets, is designed to increase community readiness and reduce the availability of HLPs, which is hypothesized to reduce HLPs use among children. The CPM is being tested in Alaskan rural communities as part of an inprogress eight-year National Institute on Drug Abuse randomized-controlled trial. This paper presents the CPM conceptual framework, describes the model, and highlights community participation, challenges, and lessons learned from implementation of the model over a 21-month period.

A community prevention intervention to reduce youth from inhaling and ingesting harmful legal products

Youth use of harmful legal products, including inhaling or ingesting everyday household products, prescription drugs, and over-the-counter drugs, constitutes a growing health problem for American society. As such, a single targeted approach to preventing such a drug problem in a community is unlikely to be sufficient to reduce use and abuse at the youth population level. Therefore, the primary focus of this article is on an innovative, comprehensive, community-based prevention intervention. The intervention described here is based upon prior research that has a potential of preventing youth use of alcohol and other legal products. It builds upon three evidence-based prevention interventions from the substance abuse field: community mobilization, environmental strategies, and school-based prevention education intervention. The results of a feasibility project are presented and the description of a planned efficacy trial is discussed.

Violent victimization and drug involvement among Mexican middle school students

AIMS

To answer the following research questions: (a) is there an association between violent victimization and exposure to opportunities to use marijuana, inhalants and cocaine and (b) is there an association between violent victimization and actual drug use among youth with drug-using opportunities?

DESIGN

Cross-sectional survey.

SETTING

Two middle schools located in the Historic Downtown area of Mexico City.

PARTICIPANTS

The entire body of students (n = 767; mean age 13.8 years, 52% males).

MEASUREMENTS

Qualitative research was used to develop questions on drug exposure opportunities and violent victimization. Standardized questions on life-time alcohol, tobacco, marijuana, inhalant drugs and cocaine use were also included, as well as questions on violent victimization and other covariates.

FINDINGS

One-quarter (25%) of students had an opportunity to try marijuana, inhalant drugs or cocaine; 35% who had an opportunity actually used at least one drug. In this sample, 59% had been victimized violently. Youth who had been victimized had greater odds of opportunities to use drugs compared to those who had not been victimized [adjusted odds ratio (OR) = 3.8; 95% confidence interval (CI), 2.4, 6.1]. Once exposure opportunity is taken into consideration, no association was evident between violent victimization and actual drug use (adjusted OR = 0.9; 95% CI, 0.4, 2.1).

CONCLUSIONS

It is possible to trace back the association between violent victimization and drug use to differences in exposure to opportunities. Limitations considered, this study suggests interventions to improve micro and macro contexts, such as families, schools and communities, so young people can have better places to live and develop.

Family attention and tobacco smoking among adolescents in Central America, Panama, and the Dominican Republic

This study examined the association between family attention and tobacco use among 5549 adolescent students in five Central American countries, Panama, and the Dominican Republic who participated in a survey of drug use in 1994. Drug use and other variables were assessed using an adapted version of the Drug Use Screening Inventory (DUSI) in Spanish. Students with the highest level of family attention had a lower occurrence of tobacco smoking than students with the lowest level of family attention. Country-specific analyses show similar associations. These findings underscore the need to understand tobacco use in Central America and neighboring countries and to test whether interventions aimed at enhancing parental-child attention, communication, and monitoring reduce the incidence of tobacco use among youths.

Use of alternating logistic regression in studies of drug-use clustering

This article describes the alternating logistic regression (ALR) method, and places this method in the context of other statistical approaches to the analysis of complex survey data, including the conditional form of logistic regression with matching on neighborhood characteristics. Unlike conditional logistic regression, the ALR method provides for an explicit estimation of the magnitude of clustering of drug use within neighborhoods and within subgroups of the neighborhood defined by male-female or age indicators, with and without covariate adjustments. The application of these ALR methods is illustrated with estimates for the magnitude of clustering of daily marijuana use and weekly marijuana use within neighborhoods of the United States, based on data from the National Household Survey on Drug Abuse samples from 1990 through 1996.
