Abstract

Purpose

We investigated the contributions of individual, family, and community-level factors for explaining alcohol use and smoking among rural Mexican adolescents.

Methods

As part of a national survey, 3922 adolescents and their mothers from 333 poor, rural communities in seven Mexican states provided cross-sectional data on family-level, socioeconomic, and psychosocial factors, and individual-level data on substance use and psychological symptoms. Community standard of living was also assessed.

Results

Generalized linear models adjusted for sampling design indicated that adolescents' use of alcohol was associated with being male, older, employment, and having a mother who used alcohol. Being from an indigenous family living in a majority-indigenous community was associated with less alcohol use. Family income, family size, and community standard of living were not directly associated with adolescents' alcohol use. Current smoking was associated with being male, older, and more anxious, having a mother who smoked, and having a mother with higher educational attainment. Further analyses indicated patterns in which adolescents' alcohol use was moderated by gender and ethnicity.

Conclusions

Beyond the contribution of male gender and age as risk factors, maternal substance use uniquely explained variability in alcohol and cigarette use among Mexican adolescents from rural communities. Indigenous ethnicity and living in majority-indigenous community settings appeared to confer protective benefits with respect to alcohol. These findings extend prior research in Mexico and in other countries that identify the combined importance of developmental contexts and individual-level factors for adolescent health.

Use of Alcohol and Tobacco in Mexico

The present study investigates individual-, family-, and community-level factors associated with alcohol and tobacco use within a large sample of rural Mexican adolescents living in poverty. Youth in developing countries are a key population to study given the increasing trajectory of alcohol and tobacco consumption, and the strong marketing efforts targeted toward these youth by producers of alcohol and tobacco [9], [10]. Youth in rural Mexico are of particular interest in light of the growing

Study design and sampling

The present study was conducted with 3922 adolescents (ages 15 to 19; mean age = 16.6 years; SD = 1.3) and their mothers from 333 rural communities as part of the 2003 Mexican National Social Welfare Survey, which was part of the evaluation of the large scale poverty alleviation program Oportunidades (previously Progresa). Cross-sectional data from this survey regarding nutrition and mental health have been published previously [28], [29]. The survey was designed to sample the poorest (income

Results

Frequencies and percentages for study variables are shown in Table 1. As described above, the design was intended to include families in the most economically disadvantaged rural communities. Not surprisingly, the percentage of majority-indigenous communities represented in the sample was high, at 28%. Although the majority of towns had street lighting and a health center or medical personnel, only 18% of communities had the basic infrastructure of a drainage system for waste and water.

Discussion

This study investigated the contributions of individual, family, and community-level characteristics for explaining alcohol and tobacco use among rural Mexican adolescents. Consistent with prior research conducted in other Mexican settings, individual-level characteristics of being older and male were each independently associated with greater use of alcohol and tobacco. This disparity was more striking for smoking than for alcohol. Adolescents' self-reported anxiety symptoms also uniquely
