The Influence of Perceived Parenting on Substance Initiation Among Mexican Children

Parents shape their children\u27s behaviors and impact their developmental trajectories. Despite this, few studies have examined the potential relationship between child reported parenting factors and lifetime substance use and use intentions. The current study examined the potential impact of parenting factors (i.e., positive parenting, supervision, parental illicit substance use, substance-specific communication) on early substance use and intentions among Latinx children. Data for the present study utilized a representative sample of Mexican children (n = 52,171; 5th and 6th grades) who participated in a national survey on substance use. Children reported their demographics, lifetime substance use/intentions, and perceived parenting characteristic and practices. Child reported parental (i.e., individual or both parents) illicit substance use was associated with the largest increases in risk for reporting lifetime use of all substances examined. Higher levels of positive parenting were consistently associated with reductions in risk for reporting intentions for and use of all substances examined. Parent-child substance specific communication was not significantly related to child reported lifetime use or use intentions, with the exception of a minor decrease in the odds of reporting lifetime inhalant use. Supervision was associated with small to modest increase in risk. Substance use prevention efforts targeting Latinx populations may benefit from promoting positive parenting and direct supervision during childhood. Targeted prevention efforts may be needed for Latinx children exposed to parental illicit substance use, as they may be especially at risk for early substance initiation

Early Adolescent Substance Use in a National Sample of Mexican Youths: Demographic Characteristics that Predict Use of Alcohol, Tobacco, and Others Drugs

The United States and Mexico have seen significant increases in the prevalence of substance use among Latinx adolescents in the last 20 years. Research is needed to address rising national rates of substances use to inform the development of policies and intervention programs targeting Latinx youth. Our primary aim was to identify demographic factors associated with substance initiation and use among elementary age Latinx youth. Data for the present study include 52,171 elementary students in 5th and 6th grades, who participated in the National Survey of Drug Use Among Students (ENCODE) in Mexico. Youths reported demographic information, rates of substance use for alcohol, tobacco, marijuana, inhalant, and other substances, or intention for first time substance use. Findings suggest that Latinx youth who were boys, of indigenous heritage, nonreligious, and overage for their grade were especially at risk for reporting lifetime alcohol, tobacco, marijuana, inhalant, and other substance use. Boys and youth with indigenous heritage were more likely to report intentions to try alcohol, tobacco, and other substances for the first time. High subjective economic status was associated with lower risk for reporting lifetime tobacco use and substance use intentions in general. Efforts are needed to disseminate accessible substance use prevention programs during early adolescence to encourage positive developmental trajectories among Latinx youths at an elevated risk for substance initiation and use. Clinical and research implications are discussed

Parent Characteristics and Practices Classify Lifetime Substance Use Among Mexican Children

The objective of this study is to determine whether parent characteristics and practices differentiate between substance using and non-using children in Mexico. Data consisted of 52,171 children (i.e., 5th and 6th grade) who participated in the National Survey of Drug Use Among Students. The relative importance of student reported parenting factors in classifying lifetime substance use were assessed across outcomes with a logistic regression algorithm. Machine learning algorithms utilizing parent characteristics and practices classifed tobacco, marijuana, inhalants, and other substance use. Parenting factors were poor classifers of lifetime alcohol use. The algorithm generally selected important classifers broadly associated with parental illicit substance use and monitoring practices across child substance use outcomes. Findings suggest that leveraging parental infuences during childhood may be a high value point of intervention for preventing non-alcoholic substance use. Important classifers identifed by the current study represent potential targets for childhood substance use prevention efforts

Innovative Identification of Substance Use Predictors: Machine Learning in a National Sample of Mexican Children

Machine learning provides a method of identifying factors that discriminate between substance users and non-users potentially improving our ability to match need with available prevention services within context with limited resources. Our aim was to utilize machine learning to identify high impact factors that best discriminate between substance users and non-users among a national sample (N = 52,171) of Mexican children (i.e., 5th, 6th grade; Mage = 10.40, SDage = 0.82). Participants reported information on individual factors (e.g., gender, grade, religiosity, sensation seeking, self-esteem, perceived risk of substance use), socioecological factors (e.g., neighborhood quality, community type, peer influences, parenting), and lifetime substance use (i.e., alcohol, tobacco, marijuana, inhalant). Findings suggest that best friend and father illicit substance use (i.e., drugs other than tobacco or alcohol) and respondent sex (i.e., boys) were consistent and important discriminators between children who tried substances and those that did not. Friend cigarette use was a strong predictor of lifetime use of alcohol, tobacco, and marijuana. Friend alcohol use was specifically predictive of lifetime alcohol and tobacco use. Perceived danger of engaging in frequent alcohol and inhalant use predicted lifetime alcohol and inhalant use. Overall, findings suggest that best friend and father illicit substance use and respondent’s sex appear to be high impact screening questions associated with substance initiation during childhood for Mexican youths. These data help practitioners narrow prevention efforts by helping identify youth at highest risk
