Perceived Access and Parental Monitoring as Moderators of Impulsivity and Marijuana Use Among Adolescents

The social and political climate regarding marijuana use has been changing in the US over the past decade. Research suggests that many adolescents report relatively easy access to marijuana and perceptions that recreational use involves minimal harm despite a growing body of research implicating the deleterious effects of use on cognitive and psychological development. Not surprisingly, prevalence rates have been rising in recent years, making it important to identify risk and protective factors associated with adolescent marijuana use. We tested a 3-way interaction model designed to (a) examine the relationship between behavioral impulsivity and marijuana use in adolescents, and (b) evaluate the roles of perceived access and parental monitoring as moderators of this relationship. High school students (N = 498, M _age  = 15.7, 53% female, 77% White) completed an anonymous self-report assessment examining substance use, perceived access, and psychosocial factors related to substance use (i.e., behavioral impulsivity and parental monitoring). Results indicated that higher levels of impulsivity, greater access, and reduced parental monitoring were related to marijuana use. Significant moderating effects were found for perceived access and parental monitoring, such that use was greater for adolescents who perceived that marijuana was easier to acquire and for those with lower levels of parental monitoring. Among individuals with greater levels of impulsivity, parental monitoring reduced the impact of perceived access. Overall, results highlight risk and protective factors related to adolescent marijuana use and indicate that parental monitoring can be an effective means for reducing consumption.     

Peer-Planned Social Activities for Preventing Alcohol Use Among Young Adolescents

ABSTRACT: The Project Northland peer participation program tested the feasibility of involving students in the planning and promotion of alcohol-free social activities for their peers and to determine whether such participation was associated with reduced alcohol use. The peer program was offered in 20 northeastern Minnesota schools when the study cohort was in seventh grade; students completed a survey in the beginning of sixth grade and at the end of sixth grade and seventh grade. Nearly 50% of the study cohort participated in the program. At the end of seventh grade, after controlling for confounders, an association was observed between student involvement with planning activities and a lower rate of alcohol use. This association was strongest among students who had reported alcohol use at the beginning of sixth grade. This cohort study suggests adolescent involvement in planning their own alcohol-free activities may be an efficacious strategy to prevent or reduce the prevalence of alcohol use among youth. Future studies are warranted to evaluate this association using experimental research designs.     

Relationship Between Neighborhood Context, Family Management Practices and Alcohol Use Among Urban, Multi-ethnic, Young Adolescents

We examined relationships between alcohol-related neighborhood context, protective home and family management practices, and alcohol use among urban, racial/ethnic minority, adolescents. The sample comprised 5,655 youth who were primarily low SES (72%), African American (43%) and Hispanic (29%). Participants completed surveys in 2002–2005 (ages 11–14 years). Items assessed alcohol use, accessibility of alcohol at home and parental family management practices. Neighborhood context measures included: (1) alcohol outlet density; (2) commercial alcohol accessibility; (3) alcohol advertisement exposure; and (4) perceived neighborhood strength, reported by parents and community leaders. Structural equation modeling was used to assess direct and indirect relationships between alcohol-related neighborhood context at baseline, home alcohol access and family management practices in seventh grade, and alcohol use in eighth grade. Neighborhood strength was negatively associated with alcohol use (β = −0.078, p ≤ 0.05) and exposure to alcohol advertisements was positively associated with alcohol use (β = 0.043, p ≤ 0.05). Neighborhood strength and commercial alcohol access were associated with home alcohol access (β = 0.050, p ≤ 0.05 and β = −0.150, p ≤ 0.001, respectively) and family management practices (β = −0.061, p ≤ 0.01 and β = 0.083, p ≤ 0.001, respectively). Home alcohol access showed a positive association with alcohol use (β = 0.401, p ≤ 0.001). Tests for indirect effects suggest that home alcohol access may partially mediate the relationship between neighborhood strength and alcohol use (β = 0.025, p < 0.062). Results suggest inner-city parents respond to environmental risk, such that as neighborhood risk increases, so also do protective home and family management practices. Parent engagement in restricting alcohol access and improving family management practices may be key to preventive efforts to reduce alcohol use.

Effects of Alcohol Use Initiation Patterns on High-Risk Behaviors among Urban,Low-Income,Young Adolescents

This study examined associations between patterns of alcohol use initiation and progression from age 12 to 14 years and recent cigarette and marijuana use, and violent and delinquent behavior at age 14. The study sample (n = 2,193) was predominantly African American or Hispanic (43% and 37%, respectively) and low-income (68% receiving free, or reduced price, lunch). They completed classroom-based surveys when in 6th–8th grades. Multilevel latent class analyses were used to identify the heterogeneous alcohol use trajectories. Linear and logistic mixed-effects regression was then used to examine the association between these patterns and high-risk behaviors in 8th grade. Five alcohol use trajectories were identified: (1) No Use (63.3%), (2) Onset of Consistently Infrequent Use at Age <12 (13.3%), (3) Onset of Monthly Use at Age 14 (9.9%), (4) Onset of Monthly Use at Age 13 to Heavy Use at Age 14 (6.6%), and (5) Onset of Consistently Heavy Use at Age 12 (6.9%). Relative to non-users, membership in any of the alcohol use trajectory classes was significantly associated with greater past month cigarette and marijuana use, as well as violent behaviors in 8th grade. Higher levels of delinquent behaviors were significantly associated with membership in all but one of the alcohol use trajectory classes relative to the “no use” class. Results suggest that any use of alcohol in early adolescence is associated with other high-risk behaviors and support the critical need for efforts to prevent early initiation and progression of alcohol use among youth as a key component to prevent future high-risk behaviors.     

Drug Use and Anticipated Parental Reaction Among Rural School Pupils in Zimbabwe

Study participants included 285 secondary school pupils in Zimbabwe who responded to a questionnaire assessing alcohol, tobacco, and marijuana use, and anticipated parental reaction to the pupil's drug-taking behavior. Results showed nearly 17% of the sample had used alcohol, 8% used tobacco, and 5% had used marijuana during the past seven days prior to questionnaire administration. Results regarding intentions to use alcohol, tobacco, and marijuana in the future show pupils' interest highest in using alcohol. Nearly 34% indicated intentions to use alcohol during the next year, while 16% reported intentions to use tobacco, and 12.9% indicated intentions to use marijuana. Nearly 17% reported they felt their parents would be favorable to their use of alcohol. Anticipated parental approval for tobacco and marijuana was 13.6% and 10.8%, respectively. Though current use and future intentions among the sample are not as high compared to similar populations in developed countries, this study suggests Zimbabwe should consider expanding its drug education effort in the school setting. Research to identify effective educational strategies to curb further increases in adolescent drug taking behavior also needs to be explored and identified.

Emotional Distress and Mental Health Service Use Among Urban Homeless Adolescents

The Expanded Behavioral Model for Vulnerable Populations was used to examine the predisposing, enabling, and need factors associated with mental health service use in a homeless adolescent sample (N = 688). Among all youth, 32% perceived a need for help with mental health problems and 15% met Brief-Symptom Inventory (BSI) criteria for emotional distress. The rate of mental health service use in our sample was 32%. One enabling factor, having a case manager/discussed mental health concerns, and one need factor, which met criteria for BSI, were found to be associated with mental health service use in the past 3 months. The majority of youth who used mental health services had obtained services from crisis centers. Among those who perceived a need for help with mental health problems but who did not use services, the most common barrier was not knowing where to go or what service to use (57%). These findings suggest that due to the high prevalence of mental health problems among homeless youth, it would be helpful for service providers coming into contact with youth to make them aware of existing community resources for mental health services; making youth aware of these resources may in turn decrease the rate of crisis center use and instead allow youth to receive mental health services in outpatient settings that provide continuity of care.Research was conducted in collaboration with the David Geffen School of Medicine at University of California, Los Angeles, Department of Family Medicine (Dr. M.R. Solorio, Mr. S. Trifskin, and Dr. M.A. Rodríguez); NPI-Semel Institute for Neurosciences, Center for Community Health, University of California, Los Angeles (Dr. N.G. Milburn); and School of Public Health, Department of Health Services, University of California, Los Angeles (Dr. R.M. Andersen).     

Universal Family-Focused Intervention with Young Adolescents: Effects on Health-Risking Sexual Behaviors and STDs Among Young Adults

Considering the prevalence and consequences of health-risking sexual behaviors (HRSBs) and STDs among young adults, their prevention is a public health priority. Emerging etiological and prevention outcome literatures suggested study of the long-term effects of universal family-focused interventions on young adult HRSBs and STDs. Although earlier studies have demonstrated intervention impact on adolescent substance misuse, no study has examined universal family-focused intervention effects on young adult HRSBs and STDs via reductions in adolescent misuse. Sixth grade students and their families enrolled in 33 rural Midwestern schools were randomly assigned to experimental conditions. Self-report questionnaires provided data at pretest (Ns?=?238, 221, and 208 for the Iowa Strengthening Families Program [ISFP], Preparing for the Drug Free Years [PDFY], and control groups, respectively), with seven data points through young adulthood (age 21). In latent growth modeling, three young adult HRSB measures (number of sexual partners, condom use, substance use with sex) and lifetime STDs were specified as distal outcomes mediated by adolescent substance initiation growth factors (average level and rate of change). Results showed that the models fit the data and, except for condom use, there were significant indirect effects, with a higher frequency of significant findings for ISFP. The model additions of direct intervention effects on young adult outcomes generally were not supported, consistent with a model positing that long-term intervention effects on young adult HRSBs and STDs outcomes are indirect. As an indication of the practical significance of long-term effects, analyses revealed relative reduction rates ranging from 6 % to 46 % for significant outcomes.

Tracking of Blood Pressure Among Adolescents and Young Adults in an Urban Slum of Puducherry

Background:

Early diagnosis of hypertension (HT) is an important strategy in its control. Tracking of blood pressure (BP) has been found useful in identifying persons with potential HT, particularly in youngsters. A cohort of 756 subjects (with baseline information as a cross-sectional study in 2002) was followed up in 2006 to comment on the distribution of BP and its attributes.

Objectives:

To track BP distribution in a cohort of adolescents and young adults, and assess the persistence of high/low normotensives; to measure the incidence of HT and study the relationship of BP with age, sex, socioeconomic status, BMI, physical exercise, salt intake, smoking and alcohol consumption.

Materials and Methods:

The baseline study cohort (2002) of 756 subjects (19-24 years) in urban field area of Department of Preventive and Social Medicine, JIPMER, was followed up between May and November 2006 by house visits for measurement of sociodemographic variables, anthropometry, salt intake, physical activity and BP.

Results:

A total of 555 subjects from the 2002 cohort were contacted (73.4%), in that 54.5% subjects who were below 5^th percentile, 93.6% subjects between 5^th and 95^th percentiles and 72% of those above 95^th percentile previously persisted in the same cut-offs for systolic blood pressure (SBP). The corresponding figures for diastolic blood pressure (DBP) were 46.2, 92.2 and 74.1%, respectively. Shift from one cut-off to another was not significant for both SBP and DBP, proving the tracking phenomenon. Annual incidence of HT was 9.8/1000. Baseline BP was the significant predictor of current BP for the entire cohort; BMI and salt intake were significant predictors only in certain sections of the study cohort.

Conclusions:

Early diagnosis of hypertension even among adolescents/young adults is an important preventive measure, as tracking exists in the population.     

Waterpipe or Hookah-Related Poisoning Events Among U.S. Adolescents and Young Adults

PurposeWaterpipe or hookah use is associated with carbon monoxide poisoning and effects such as nausea and vomiting. We examined the public health burden of poisoning events involving hookah tobacco in the U.S., especially among adolescents and young adults.MethodsWe analyzed events involving hookah tobacco that were reported to U.S. poison control centers between 2001 and 2017 by age and over time as well as by medical outcome, health care level, and clinical effects.ResultsA total of 276 relevant poisoning events involving hookah were reported. Among the 248 individuals with a specific age reported, 35 (14.1%) were aged between 10 and 17 years and 136 (54.8%) were aged between 18 and 24 years. Common clinical effects included dizziness/vertigo, nausea, headache, and vomiting.ConclusionsHookah tobacco use is associated with poisoning events consistent with exposure to high levels of carbon monoxide.     

Alcohol and Drug Use Among Gang Members: Experiences of Adolescents Who Attend School

BACKGROUND: Problems related to gangs have been noted in large cities and in many schools across the United States. This study examined the patterns of alcohol, drug use, and related exposures among male and female high school students who were gang members. METHODS: Analyses were based on the Youth Violence Survey, conducted in 2004, and administered to over 80% of eligible public school students in grades 7, 9, 11, and 12 (N = 4131) in a high-risk, urban school district. The self-administered survey, completed during a class period, included measures of alcohol and drug use and related exposures. Tests of associations were determined using chi-square tests and logistic regression analyses. RESULTS: In this study, 8.8% of students reported gang membership. Students who initiated alcohol use prior to age 13 (OR = 4.90; 95% CI: 3.65–6.58), who drank alcohol 3 or more times per week (OR = 9.57; 95% CI: 6.09-15.03) and who used drugs 3 or more times per week (OR = 6.51; 95% CI: 4.59-9.25) were more likely to report gang membership than students who did not report alcohol or drug use. Boys were more likely than girls to report alcohol-related fighting and drug selling. DISCUSSION: Gang members were significantly more likely than non-gang members to have initiated alcohol early, to have reported a high prevalence of alcohol use, to have engaged in alcohol-related physical fighting, peer drinking, drug use, drug selling, peer drug selling, and having seen drug deals in their neighborhood. Schools may serve as a critically important source for intervention and prevention efforts for gang members, especially those in 7th grade, who still attend school.     

Tap or Bottled Water: Drinking Preferences Among Urban Minority Children and Adolescents

The last decade has seen an increasing trend in consumer preference of bottled water over tap water. Little is known what type of water children and adolescents prefer for drinking and what their parents think of their community tap water. The study objective was to assess drinking water preferences, perceptions of the qualities of tap water and bottled water, and fluoride knowledge in an urban pediatric population. We conducted an anonymous survey of a convenience sample of caretakers of children and adolescents at an urban clinic regarding their preferences for tap or bottled water, their perceptions of the quality of tap and bottled water and their knowledge of fluoride. Of the 208 participants (79% African American, 9% Latino), 59% drank tap water, 80% bottled water. Only 17% drank tap water exclusively, 38% drank bottled water exclusively, 42% drank both. We found no significant differences in water preferences across age groups, from infancy to adulthood, or among ethnic groups. Ratings for taste, clarity, purity and safety were significantly higher for bottled water than tap water (P < 0.001). Only 24% were aware of fluoride in drinking water. We conclude bottled water was preferred over tap water in an urban minority pediatric population. Perceptions of the qualities of water seemed to drive drinking preferences. Public health strategies are needed to increase public awareness of the impact of bottled water consumption on oral health, household budgets and the environment.     

Sexual Behavior and Drug Use Among Asian and Latino Adolescents: Association with Immigrant Status

This paper contributes new evidence on the association between immigrant status and health by describing and attempting to explain patterns of co-occurring sex and drug use behaviors among Asian and Latino adolescents in the United States. Nine patterns of sex and drug use behaviors were identified from a cluster analysis of data from 3,924 Asian and Latino youth (grades 7–12) who participated in the National Longitudinal Study of Adolescent Health (Add Health). The relationship between immigrant status and risk cluster membership was evaluated with multinomial logistic regression. Compared to foreign-born youth, U.S. born Asian and Latino adolescents were more likely to engage in sex and drug risk behaviors. Family and residential characteristics associated with immigrant status partly accounted for this finding. The results indicate that among Asian and Latino adolescents, assimilation to U.S. risk behavior norms occurs rapidly and is evident by the second generation.     

Effects of Program Exposure and Engagement With Tailored Prevention Communication on Sun Protection by Young Adolescents

Few family-based interventions to increase sun safe behavior among adolescents have been evaluated. The present study tested an intervention that included tailored and nontailored print communications delivered by mail to adolescents (age 11 to 15) and their parents who were also participating in an evaluation of an in-school intervention. The use of sunscreen, protective clothing, and avoidance of the sun were promoted, and family communication and environmental change strategies were fostered. Adolescents and their parents were pretested in May of 2002 and posttested from August to October. Adolescents (N = 599) were stratified on experimental condition in the in-school study (in-school intervention vs control) and randomly were assigned from within strata to receive (N = 288) or not receive (N = 311) the summer intervention materials. No statistically significant effects were found for adolescents between the randomized experimental conditions. Parents' had increased knowledge (F = 5.52, p < .05) and propensity to have their child wear sunglasses (F = 4.07, p < .05). Greater program exposure/engagement led to enhanced sun protection behavior (e.g., fewer sunburns) and psychosocial factors among adolescents and parents. Greater exposure/engagement led to improvements in family interaction and home environment (e.g., shade audit completed). Future research is needed on exposure/engagement with family-based health messaging and on family-based sun safety programs for adolescents.     

Seat Belt Use Among Overweight and Obese Adolescents

Motor vehicle crashes are the leading cause of death for adolescents. Previous studies with adults found an association between weight status and decreased use of seat belts. Research has also found significantly higher morbidity and mortality rates in obese individuals who are involved in motor vehicle crashes. If these relationships hold true in obese adolescents they represent additional risk factors for complications from motor vehicle trauma. Given the prevalence of obesity in adolescents (17.4%) and the increased risk of harm associated with obese individuals involved in motor vehicle crashes, this study explored whether there was an association between obesity in adolescents and their use of seat belts. Initial investigation found that rarely/never wearing seat belts was significantly greater for African Americans (22.6%), 18 years of age or older (19.4%), lived with adults other than both parents (15.7%), and males (15.4%). Bivariate logistic regression analysis controlling for demographic variables found that there was no statistically significant difference between overweight and normal weight adolescents. However, obese students were 1.72 times as likely as normal weight students to never or rarely wear their seat belts when riding in a car as a passenger. In particular, obese females and obese students in the middle school age ranges were statistically significantly more likely than normal weight students to never or rarely wear their seat belts.     

Dual Use of Condoms With Other Contraceptive Methods Among Adolescents and Young Women in the United States

PurposeTo estimate the prevalence of and factors associated with dual method use (i.e., condom with hormonal contraception or an intrauterine device) among adolescents and young women in the United States.MethodsWe used 2006–2010 National Survey of Family Growth data from 2,093 unmarried females aged 15–24 years and at risk for unintended pregnancy. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to assess the associations between dual method use at last sex and sociodemographic, behavioral, reproductive history, and sexual behavior factors.ResultsAt last sex, 20.7% of adolescents and young women used dual methods, 34.4% used condoms alone, 29.1% used hormonal contraception or an intrauterine device alone, and 15.8% used another method or no method. Factors associated with decreased odds of dual method use versus dual method nonuse included having a previous pregnancy (aOR = .44, 95% CI .27–.69), not having health insurance coverage over the past 12 months (aOR = .41, 95% CI .19–.91), and having sex prior to age 16 (aOR = .49, 95% CI .30–.78).ConclusionsThe prevalence of dual method use is low among adolescents and young women. Adolescents and young women who may have a higher risk of pregnancy and sexually transmitted infections (e.g., those with a previous pregnancy) were less likely to use dual methods at last sex. Interventions are needed to increase the correct and consistent use of dual methods among adolescents and young women who may be at greater risk for unintended pregnancy and sexually transmitted infections.
