Age of Onset, Current Use of Alcohol, Tobacco or Marijuana and Current Polysubstance Use Among Male and Female Mexican Students.

AIMS: This study aimed to examine alcohol, tobacco or marijuana use onset and associations between age of onset and current use, and between age of onset and current polysubstance use among a sample of Mexican young people aged 17-20 years. METHODS: Alcohol, tobacco, marijuana and other substance use were identified in a 2012 cross-sectional survey of male and female students entering first year university in Mexico City. Chi-square tests and logistic regression models examined associations between gender, age of onset, order of onset, family substance use and current polysubstance use among 22,224 students. RESULTS: The largest proportions of males and females initiated alcohol at age 15, tobacco at ages 15-16 and marijuana at ages 16-17. Earlier alcohol and tobacco initiation was associated with past 30-day use of the same substance. Gender differences in alcohol and tobacco use were small but males were significantly more likely than females to use marijuana and be polysubstance users. Family substance use was associated with earlier onset. There was a significant association between the earliest age of any of the three substances and current polysubstance use. CONCLUSIONS: A number of contextual and cultural factors in Mexico may be contributing to early onset, continued use and polysubstance use and deserve attention in research and by prevention programs.

Parental monitoring and family relations: associations with drinking patterns among male and female Mexican students.

INTRODUCTION: Parental monitoring and family relations are recognized as protective factors for youth alcohol use. The purpose of this study was to investigate perceived parental monitoring and family relations among subgroups of Mexican youths with different patterns of drinking behaviors and consequences. METHODS: A latent profile analysis (LPA) identified profiles of drinking behavior in a cross-sectional survey of entering first year university students. Multinomial regression examined associations between parental monitoring, family relations and drinking profiles among 22,224 students. RESULTS: Both lower perceived parental monitoring and weaker perceived family relations were associated with heavier drinking profiles among males and females, but more strongly associated with female than male heavier drinking profiles. Being older, having parents with lower education, and not living with parents were also associated with lower parental monitoring and weaker family relations. There was a general trend of lower parental monitoring and weaker family relations as the profiles increased from Non/Infrequent-No Consequences to Excessive-Many Consequences Drinkers. Lower perceived parental monitoring and weaker perceived family relations were more strongly associated with drinking profiles among females than among males. Both the parental monitoring and family relations scales had similar associations with drinking profiles. CONCLUSIONS: Findings suggest that drinking norms and values may contribute to any protective influences of parental monitoring and family relations on Mexican youths' drinking. Research about changes in drinking norms, contextual factors, and youth-parent trust would inform the utility of parental monitoring or family relations as protective strategies against alcohol misuse among Mexican and Mexican American youths and also youths from other backgrounds.

Natural mentors and youth drinking: a qualitative study of Mexican youths.

Parental influences on youth drinking are well documented but not the influence of extended family members. This article explores extended family influences on alcohol use among Mexican youths and whether extended family members can be considered natural mentors. We conducted a qualitative study using ethnographic open ended interviews with 117 first year university students in Mexico City. The ethnographic interviews revealed six drinking groups: excessive, heavy, regular, occasional, abstainers and non drinkers. Youths reported close relationships with extended family members who provided counsel and acted as representatives of familial norms and values. The alcohol beliefs and behaviors of these family members, including their alcohol misuse, had a positive influence on youths' alcohol attitudes. The naturally occurring mentoring relationships of Mexican extended family members can positively influence moderate youth drinking. Natural mentoring relationships should be encouraged and facilitated in prevention efforts for Mexican youths, Mexican-American youths and potentially other Hispanic/Latino youths.

Alcohol Use among Mexican Youths: Is Familismo Protective for Moderate Drinking?

The construct of familismo has been identified as a potential protective cultural value in Hispanic cultures. This paper considers familismo and alcohol use among young people in Mexico. We conducted a qualitative study using ethnographic open ended interviews with 117 first year students at a large free public university in Mexico City between April-May 2011. The findings indicate that dimensions of familismo can act as protective factors against misuse of alcohol among Mexican youths and may be protective for moderate drinking. Future research should explore the relationship of familismo to gender roles and other cultural values during adolescence. Given the enduring influence of Mexican cultural values among Mexican Americans the research has implications for prevention programs for both Mexican and Mexican American youths.

Drinking patterns and victimization among male and female students in Mexico.

AIMS: The purpose of this study is to estimate the prevalence of alcohol use and alcohol-related consequences, identify drinking profiles using latent profile analysis (LPA), and investigate associations between profiles and violent victimization among young people in Mexico. METHODS: LPA identified profiles of drinking behavior in a survey of entering first year university students. Multinomial and logistic regression examined associations between drinking patterns, socio-demographic variables and violent victimization. RESULTS: The LPA identified five profiles of behaviors and consequences among the 22,224 current, former and never drinkers: Non/Infrequent-No Consequences, Occasional-Few Consequences, Regular-Some Consequences, Heavy-Many Consequences and Excessive-Many Consequences drinkers. The Occasional-Few Consequences profile comprised the largest, and the Excessive-Many Consequences profile the smallest, group of drinkers. Multinomial regression showed males and older students more likely to be Heavy or Excessive-Many Consequences drinkers. Living alone was associated with higher odds, and higher maternal education with lower odds, of being a Non/Infrequent-No Consequences drinker. Heavier drinking profiles were more likely to experience violent victimization adverse consequences. Logistic regression showed male and female Heavy and Excessive-Many Consequences drinkers had the highest odds, and Non/Infrequent drinkers the lowest odds, of experiencing any victimization. CONCLUSION: Findings suggest changes in male and female drinking behavior and a continuation of the established pattern of infrequent but high consumption among Mexican youths. Both male and female Heavy and Excessive-Many Consequences drinkers were at elevated risk for experiencing victimization. Identifying cultural gender norms about drinking including drinker expectations and drinking context that contribute to these patterns can inform prevention efforts.

Changes in alcohol use among first year university students in Mexico.

BACKGROUND: Alcohol use and misuse is widespread among university students in many countries. Specific cultural factors may impact alcohol use after entering university. OBJECTIVE: This paper considers changes in alcohol use among first year university students in Mexico. METHODS: A qualitative study using ethnographic interviews with 57 female and 60 male student drinkers in Mexico City from March to June 2011. Each interview was evaluated by a set of thematic codes developed inductively from the interviews. Findings from excessive, heavy, regular, occasional drinkers, abstainers, and non-drinkers were analyzed to explore whether or not linkages existed between and/or among particular themes. RESULTS: Students reported factors associated with changes in role and status, friendships, and increased autonomy as reasons for increasing or decreasing their alcohol use after entering university. CONCLUSIONS/IMPORTANCE: Understanding the influence of Mexican cultural norms on alcohol use among Mexican and Mexican Americans can be helpful in informing studies and preventive efforts among both Mexican and Mexican American young people.

Parental monitoring and alcohol use among Mexican students.

Parental monitoring has been described as a protective factor and useful strategy to prevent substance misuse among youths. The aim of this study was to examine whether perceived parental monitoring influences frequency of alcohol use, age of drinking onset and risky drinking among entering public high school and university students in Mexico City. The study is a cross-sectional survey of entering first year students in the high school and university school system of a large public university in Mexico City conducted during registration at the beginning of the school year. In 2008, of 34,840 students accepted to the affiliated high schools, 28,996 students (51.8% female) completed the alcohol survey and of 37,683 students accepted into university 30,084 students (51.5% female) completed the alcohol survey. The findings suggest that compared to students with higher perceived parental monitoring those reporting lower perceived parental monitoring were more likely to report risky behavior. They were more likely to be ever drinkers, frequent drinkers, have earlier age of onset and high AUDIT scores. Overall, higher parental monitoring was strongly associated with being female and lower parental monitoring with being male. Our findings suggest that more research on parental monitoring as a protective strategy against alcohol misuse is needed. Research focusing on cultural factors including gender and age-related norms and familismo would increase knowledge of the association of parental monitoring and alcohol use among Mexican youths, Mexican American youths and potentially youths from other Hispanic backgrounds.
