Substance use among rural adolescent virgins as a predictor of sexual initiation

Associations of tobacco and alcohol use with sexual behaviors among adolescents in 59 countries: a population-based study

BACKGROUND

Sexual behaviors, particularly risky sexual behavior, has become a serious public health concern among adolescents worldwide, presenting a substantial obstacle to the prevention of sexually transmitted infections, including human immunodeficiency virus (HIV). However, there is limited research using consistent and standardized methodology to examine associations between tobacco and alcohol use frequency and both total and risky sexual behaviors among adolescents. We aimed to examine the association between tobacco and/or alcohol use with both total and risky sexual behaviors among adolescents worldwide.

METHODS

Data were collected from the Global School-based Student Health Survey, which comprised 211,847 adolescents aged 12-17 years from 59 countries. The frequency of tobacco or alcohol use during the past 30 days was categorized as 0, 1-2, 3-5, 6-9, or ≥ 10 days. Tobacco and alcohol use were also categorized as non-use, tobacco use alone, alcohol use alone, and combined use. Multi-variable logistic regression analysis was used to examine both the independent and combined associations of tobacco and alcohol use with total and risky sexual behaviors.

RESULTS

Compared with no tobacco use, the odds ratio of engaging in sexual intercourse increased with the frequency of tobacco use from 1 to 2 days to ≥ 10 days (total: 2.03 [95% confidence interval 1.47-2.81] to 3.98[2.63-6.03]; risky: 2.43[1.75-3.38] to 4.21[3.26-5.42]), as well as with the frequency of alcohol use. Overall, combined users had greater likelihood of both total and risky sexual behaviors than tobacco users alone, alcohol users alone, and non-users. Similarly, the association between risky sexual behaviors and tobacco use alone was more pronounced among adolescent girls (vs. adolescent boys), as were those of risky sexual behaviors with alcohol use alone among younger adolescents aged 12-14 years (vs. aged 15-17 years) and with tobacco and/or alcohol use among adolescents in the Western Pacific region (vs. Regions of Africa and Americas).

CONCLUSIONS

Our findings suggest independent and combined associations between tobacco and/or alcohol use with sexual behaviors among adolescents, with variations across age, sex, and WHO region.

Development, Pre-Testing and Feasibility Testing of Multi-Component Interventions, Critical for Mental Health Promotion in Primary Care among Mexican-American Adolescents Living in Rural America

Rural America is often viewed as bereft of social problems facing urban America. Rural families, however, experience stressors due to low employment rates, fewer educational opportunities, a relatively increased incidence of poverty and limited access to mental health care. These families are at increased risk for substance use, violence and associated psychological distress that occurs when failing to cope with stress. Rural children, experiencing these stressors and affected by barriers of culture, poverty and remote access to mental health care, are at higher risk for these negative health outcomes. The need for culturally appropriate intervention tailored to the target population, rural Mexican-American adolescent women, is consistently supported by evidence. A one-size-fits-all approach most likely will not effectively impact behavior and health outcomes. The fact that few studies evaluated effects of mental health interventions on multiple outcomes including substance use, violence, unintended pregnancy and STI is problematic given previously noted associations. Evidence is needed to evaluate associations between mental health interventions and these outcomes. This manuscript presents results of preliminary studies, conducted using a multi-method research approach for development, pre-testing and feasibility testing of interventions for rural primary care settings. This methodology is appropriate when dealing with the complexity of social phenomena. It provides a look at an issue from all angles and thereby the cultural context and perspective informing intervention development. These multi-component interventions are critical for mental health promotion among Mexican-American adolescent women living in rural America.

Alcohol, age at first sexual intercourse and number of sexual partners in young Mexican women

AIM

To identify the relationship between use of alcohol, number of sexual partners and age of sexual initiation.

METHOD

Descriptive-correlational study. A random sample of 319 young women (age 18-25) from Nuevo Laredo, Mexico was recruited. A sociodemographic data sheet and the AUDIT questionnaire were used. Non-parametric Spearman's rank correlation coefficient and Kruskal-Wallis H test were selected.

RESULTS

On average the participants were 20.70 years old (±2.1), had 1.86 sexual partners (±1.27), started drinking alcohol at the age of 16.82 (±1.79), and their first sexual intercourse was at the age of 17.38 (±1.65). There was a decrease in the age of onset of alcohol use (H=16.646, p<.001) and the age at first sexual intercourse (H=26.749, p<.001) on the lower their current age. The overall AUDIT score negatively correlated with the age of the participants on their first sexual intercourse (r_s=-.168, p<.001) and positively correlated with the number of sexual partners (r_s=.243, p<.001). The aforementioned correlations were more intense among the younger participants (18- and 19-year olds; p<.01).

CONCLUSIONS

There was an association between higher use of alcohol, early age of sexual initiation and number of sexual partners. Nursing professionals may address such variables simultaneously through preventive strategies directed specifically at young women.

Interaction Between Smoking Cigarettes and Alcohol Consumption on Sexual Experience in High School Students

Objectives

This study aimed to analyze nationwide representative data from the 11^th Korean Youth Health Risk Behavior Web-Based Survey to determine whether factors including socio-demographics, smoking and alcohol consumption, were factors related to high school students that had experienced sexual intercourse.

Methods

A total of 33,744 students (17,346 boys and 16,398 girls) in 1^st, 2^nd, and 3^rd grade at high school were analyzed. SPSS complex samples methods were used for analyses. Socio-demographic and health risk behaviors (type of region of residence, family structure, and economic status, student academic achievement, gender, high school grade, pocket money, student smoking, alcohol consumption, and having engaged in sexual intercourse) were considered as independent variables.

Results

There were 3.6% of girls and 9.9% of boys in high school that were sexually active. This behavior and the average number of cigarettes smoked daily, and alcohol consumed weekly, represented a dose-response relationship, after considering confounding factors. Compared with students that did not smoke or consume alcohol, smoking 1–9 cigarettes per day and consuming 1–6 cups of alcohol and group “smoking more than 10 cigarettes per day and consuming more than 7 cups of alcohol, had a 5.94 and 22.25 higher risk of having had sexual intercourse, respectively.

Conclusion

Cigarette smoking and alcohol consumption were associated with an increased likelihood of high school students engaging in sexual intercourse.

A Typology of Substance Use Among Pregnant Teens in the United States

OBJECTIVES

Previous research suggests that, in general, youth who become pregnant during their teenage years tend to report elevated levels of substance use prior to conception and substantial reductions in use during pregnancy. While such studies provide insight into aggregate patterns of adolescent substance use in relation to pregnancy, they may have the unintended effect of masking the behavioral heterogeneity of pregnant teens.

METHODS

The present study employs data from a large, population-based study of adolescents in the United States. We employ latent class analysis to identify subgroups of pregnant adolescents (ages 12-17; n = 810) on the basis of variables measuring the past 12-month and past 30-day use of an extensive array of substances.

RESULTS

Results revealed a four class solution. Classes were identified as Class 1: Abstainers (n = 344, 42.47 %), Class 2: Drinkers (n = 303, 37.41 %), Class 3: Alcohol and Cannabis Users (n = 77, 9.51 %), and Class 4: Polydrug Users (n = 86, 10.62 %). The Abstainers class had the highest proportion of Hispanic youth (34.3 %) as well as the highest proportion of youth residing in households earning less than $20,000 per year (44.2 %). The Polydrug Users class had the highest proportion of youth who were in late adolescence (75.58 %), non-Hispanic white (54.65 %), high-income (13.95 %), and in their first trimester of pregnancy (58.33 %).

CONCLUSIONS FOR PRACTICE

Findings point to an important degree of heterogeneity among pregnant teens and may have implications for the development of interventions designed for youth exhibiting disconcerting patterns of substance use prior to pregnancy.

Do alcohol and marijuana use decrease the probability of condom use for college women?

Alcohol and marijuana use are thought to increase sexual risk taking, but event-level studies conflict in their findings and often depend on reports from a limited number of people or on a limited number of sexual events per person. With event-level data from 1,856 sexual intercourse events provided by 297 college women (M age = 18 years; 71% White), we used multilevel modeling to examine associations between alcohol and marijuana use and condom use as well as interactions involving sexual partner type and alcohol-sexual risk expectancies. Controlling for alternative contraception use, partner type, regular levels of substance use, impulsivity and sensation seeking, and demographics, women were no more or less likely to use condoms during events involving drinking or heavy episodic drinking than during those without drinking. However, for drinking events, there was a negative association between number of drinks consumed and condom use; in addition, women with stronger alcohol-sexual risk expectancies were marginally less likely to use condoms when drinking. Although there was no main effect of marijuana use on condom use, these data suggest marijuana use with established romantic partners may increase risk of unprotected sex. Intervention efforts should target expectancies and emphasize the dose-response relationship of drinks to condom use.

Relationships between marijuana dependence and condom use intentions and behavior among justice-involved adolescents

The current study examined the relationships among marijuana dependence, a theoretical model of condom use intentions, and subsequent condom use behavior in justice-involved adolescents. Participants completed baseline measures of prior sexual and substance use behavior. Of the original 720 participants, 649 (90.13 %) completed follow-up measures 6 months later. There were high levels of marijuana use (58.7 % met criteria for dependence) and risky sexual behavior among participants. Baseline model constructs were associated with condom use intentions, and intentions were a significant predictor of condom use at follow-up. Marijuana dependence did not significantly influence the relationships between model constructs, nor did it moderate the relationship of model constructs with subsequent condom use. Findings suggest that the theoretical model of condom use intentions is equally valid regardless of marijuana dependence status, suggesting that interventions to reduce sexual risk behavior among both marijuana dependent and non-dependent justice-involved adolescents can be appropriately based on the model.

Early sexual debut and condom nonuse among adolescents in South Korea

BACKGROUND

The purpose of this study was to investigate the factors related to sexual debut among adolescents, and to examine the association between subject characteristics and condom nonuse among those who experienced sexual intercourse in South Korea.

METHODS

Data were obtained from the 2009 Korean Youth Risk Behaviour Survey, a nationally representative sample. Logistic regression analysis was conducted to investigate the factors related to sexual debut, associations of condom nonuse and subject characteristics.

RESULTS

Among male adolescents, age, early age at first emission, low academic achievement, living with a step-parent, perceived low level of household income, frequent drinking and smoking, and depressive feelings were associated with early sexual debut. Attending a coeducational school, living with a single biological parent and step-parent, risky health behaviour such as drinking and smoking, and depressive feelings were related risks factors for early sexual debut among female students. Factors associated with condom nonuse included early sexual debut (less than 16 years of age) (odds ratio (OR)=1.79, 95% confidence interval (CI)=1.32-2.43) and frequent smoking behaviour (OR=1.49, 95% CI=1.08-2.05) for males and early sexual debut (OR=4.37, 95% CI=1.02-18.68) and frequent drinking (OR=2.05, 95% CI=1.12-3.75) for females.

CONCLUSIONS

Appropriate interventions should be implemented for adolescents in Korea to delay sexual debut and educate them on the proper use of condoms.

Gender-specific relationships between depressive symptoms, marijuana use, parental communication and risky sexual behavior in adolescence

A large body of research has identified correlates of risky sexual behavior, with depressive symptoms and marijuana use among the most consistent psychosocial predictors of sexual risk. However, substantially less research has examined the relationship between these risk variables and adolescent risky sexual behavior over time as well as the interaction of these individual-level predictors with family-level variables such as parenting factors. Additionally, most studies have been restricted to one index of risky sexual behavior, have not taken into account the complex role of gender, and have not controlled for several of the factors that independently confer risk for risky sexual behavior. Therefore, the current study investigated the association between depressive symptoms and parameters of parenting on marijuana use, number of sexual partners and condom usage measured 9 months later for both boys and girls. Participants were 9th and 10th grade adolescents (N = 1,145; 57.7% female). We found that depressive symptoms may be a gender-specific risk factor for certain indices of risky sexual behavior. For boys only, marijuana use at Time 2 accounted for the variance in the relationship between depressive symptoms at Time 1 and number of partners at Time 2. Additionally, strictness of family rules at Time 1 was associated with the number of partners with whom girls engaged in sex at Time 2, but only among those with lower levels of depressive symptoms at Time 1. Results from the current investigation speak to the utility of examining the complex, gender-specific pathways to sexual risk in adolescents. Findings suggest that treatment of mental health and substance use problems may have important implications in rates of risky sexual behavior and, conceivably, controlling the high rates of serious individual and public health repercussions.

Brief Strategic Family Therapy: An Intervention to Reduce Adolescent Risk Behavior

This article reviews the brief strategic family therapy (BSFT; J. Szapocznik, M. A. Scopetta, & O. E. King, 1978, The effect and degree of treatment comprehensiveness with a Latino drug abusing population. In D. E. Smith, S. M. Anderson, M. Burton, N. Gotlieb, W. Harvey, & T. Chung, Eds, A multicultural view of drug abuse, pp. 563-573, Cambridge, MA: G. K. Hall & J. Szapocznik, M. A. Scopetta, & O. E. King, 1978, Theory and practice in matching treatment to the special characteristics and problems of Cuban immigrants, Journal of Community Psychology, 6, 112-122.) approach to treating adolescent drug abuse and related problem behaviors. The treatment intervention is reviewed, including specialized features such as engagement of difficult families. Empirical evidence supporting the BSFT approach is presented. We then illustrate ways in which clinicians can use the model with troubled families whose adolescents may be at risk for drug use and HIV. Finally, future directions for BSFT research are described.

Developmental relations and patterns of change between alcohol use and number of sexual partners from adolescence through adulthood

We explored two unanswered questions about the role of alcohol use in sexual behavior. First, we considered whether alcohol use temporally precedes and predicts changes in sexual behavior assessed as the number of sexual partners, whether the reverse pattern holds, or whether the association reflects a common, external cause. Second, we assessed whether associations between these behaviors change as adolescents transition to adulthood. These questions were addressed with a bivariate dual change latent difference score model. Drinking frequency and number of yearly sex partners were assessed 8 times across a 13-year period in a sample of 553 individuals. Assessment began when participants were in the 9th grade (age: M = 15.11 years, SD = 0.43). In addition to an association between the individual growth trajectories of these behaviors, alcohol use was a leading indicator of changes in number of sex partners throughout adolescence, but the reverse pattern was not supported. Of importance, the predictive association could not be explained by individual differences in impulsivity, excitement seeking, conduct problems, hostility/aggression, conventional attitudes, gender, or divorce. Finally, in a developmentally meaningful pattern, alcohol use ceased to significantly predict changes in the number of sexual partners as adolescents transitioned to adulthood.

Associations of marijuana use and sex-related marijuana expectancies with HIV/STD risk behavior in high-risk adolescents

Multiple studies suggest an association of marijuana use with increased rates of sexual risk behavior and sexually transmitted diseases (STDs). Most studies have focused on global associations of marijuana use with sexual risk outcomes and few have examined relevant cognitive variables. Adolescents in the juvenile justice system are at elevated risk for HIV/STDs and preliminary evidence suggests that marijuana is a potentially important cofactor for sexual risk behavior in this population. This study evaluated global, situational and event-level associations of marijuana use and sex-related marijuana expectancies with sexual risk outcomes in a large, racially diverse sample of adjudicated youth (n = 656, 66% male, mean age = 16.7 years). Cross-sectional and prospective analyses identified associations of marijuana use and dependence symptoms with sexual risk outcomes, including lower frequency of condom use and higher STD incidence. Stronger sex-related marijuana expectancies predicted greater intentions for and frequency of marijuana use in sexual situations. In event-level analyses that controlled for alcohol, marijuana use predicted a significantly decreased likelihood of condom use; this association was moderated by sex-related marijuana expectancies. Mediation analyses suggested that behavioral intentions partly accounted for the prospective association of expectancies with marijuana use before sex. These results provide further evidence that marijuana use is a potentially important cofactor for HIV/STD transmission in high-risk adolescents and suggest that cognitive factors could be important for characterizing this association.

Factors associated with illegal substance use initiation among young students in Mexico City

INTRODUCTION AND AIMS

To assess risk factors for illegal substances use initiation in a cohort of Mexican high-school teenage students.

DESIGN AND METHODS

Longitudinal study of a cohort of 10th grade students, with follow up at the time of their enrolment in college (3-4 year follow up). The associations of parental educational level, alcohol abuse in the family, employment status, experiences of physical and sexual aggression, sexual initiation, emotional distress and previous legal substance use at the baseline measurement, with the initiation of illegal substance use were explored.

RESULTS

The follow-up analysis was carried out in 21,616 at-risk students. The incidence of substance use initiation was 7%. Male gender (odds ratio 3.86, 95% confidence interval 3.45, 4.32), a higher father's education level, sexual initiation for women (odds ratio 2.67, 95% confidence interval 1.49, 4.79] and use of legal substances at baseline were associated with risk of substance use initiation.

DISCUSSION AND CONCLUSIONS

The social circumstances surrounding adolescents influence their risk of illegal substance consumption. Although the complex network of factors affecting substance use requires further exploring, young people at risk can be identified and should receive preventive attention.

Early sexual experience and later onset of illegal drug use among African American students on HBCU campuses

Few studies examine whether early sexual experience is associated with subsequent illegal drug use among adolescents. A sample of 7,372 African American students who had not used illegal drugs before the age of 14 were identified in the dataset of the 2001 Historically Black Colleges and Universities (HBCU) Substance Use Survey. Using self-reported ages of onset, discrete-time survival models estimated the hazard of illegal drug use onset after age 13 subsequent to first sexual intercourse. Early sex was modestly associated with subsequent illegal drug initiation, particularly among females. Drug use prevention services should be provided to youth engaged in early sexual activity.

US Latina age of sexual debut: long-term associations and implications for HIV and drug abuse prevention

This cross-sectional study explored associations among (a) age of sexual debut; (b) drug abuse; and (c) sexual risk behaviors among an urban community-based sample of 158 predominantly immigrant, Latina adults. Time in the USA and having a mother who used drugs during the participants' childhood or adolescence were significantly related to age of sexual debut. In turn, younger ages of sexual debut were associated with drug abuse and more sexual risk behaviors (greater number of sexual partners, more frequent alcohol and drug use before or during sex, greater levels of intoxication from alcohol or drugs during sex). Implications for HIV/AIDS and drug abuse clinical services and future research with US Latina populations are discussed.

Screening adolescents for substance use-related high-risk sexual behaviors

PURPOSE

This analysis was undertaken to determine whether adolescents who screened positive for high-risk substance use with the CRAFFT questions were also more likely to engage in risky sexual behaviors than their peers, and to determine the test-retest reliability of a substance use-related sexual risk behaviors inventory.

METHODS

Clinic patients 12-18 years old completed a multi-part questionnaire that included eight demographic items, the CRAFFT substance use screen, and a 14-item scale assessing sexual behaviors associated with substance use. Participants were invited to return 1 week later to complete an identical assessment battery.

RESULTS

Of the 305 study participants, 49 (16.1%) had a positive CRAFFT screen result (score of 2 or greater, indicating high risk for substance abuse/dependence) and 101 (33.9%) reported sexual contact during the past 90 days. After controlling for gender, age, race/ethnicity, and number of parents in household, adolescents with a positive CRAFFT screen had significantly greater odds of having sexual contact after using alcohol or other drugs, of having a sexual partner who used alcohol or other drugs, of having sex without a condom, and of having multiple sexual partners within the past year, compared to their CRAFFT negative peers. The substance use-related sexual risk behaviors inventory has acceptable test-retest reliability, and the 10 frequency questions have scale-like properties with acceptable internal consistency (standardized Cronbach's alpha=.79).

CONCLUSION

Clinicians should pay special attention to counseling CRAFFT-positive adolescents regarding use of condoms and the risks associated with sexual activity with multiple partners, while intoxicated, or with an intoxicated partner.

Early adolescent alcohol use and sexual experience by emerging adulthood: a 10-year longitudinal investigation

PURPOSE

The current study examined the long-term relationship of early adolescent alcohol use to number of sexual partners by emerging adulthood.

METHODS

Using data from a 10-year longitudinal study, we collected data on sixth- and seventh-grade students' alcohol use and their lifetime number of sexual partners 10 years later.

RESULTS

We found a significant effect of early alcohol use in the sixth and seventh grades on lifetime number of sexual partners 10 years later, controlling for gender, age, race, peer norms, and sensation seeking. Early age at first intercourse mediated the association between early alcohol use and number of sexual partners.

CONCLUSIONS

Interventions focused on preventing use of alcohol at an early age may have the potential to reduce risks for sexually transmitted diseases during adolescence and emerging adulthood.

Cannabis use and sexual health

INTRODUCTION

Cannabis is the most commonly used illicit substance worldwide. Despite this, its impact on sexual health is largely unknown.

AIM

The aim of this article is to examine the association between cannabis use and a range of sexual health outcomes.

MAIN OUTCOME MEASURES

The main outcome measures include the number of sexual partners in the past year, condom use at most recent vaginal or anal intercourse, diagnosis with a sexually transmissible infection in the previous year, and the occurrence of sexual problems.

METHODS

Method used in this article includes a computer-assisted telephone survey of 8,656 Australians aged 16-64 years resident in Australian households with a fixed telephone line.

RESULTS

Of the 8,650 who answered the questions about cannabis use, 754 (8.7%) reported cannabis use in the previous year with 126 (1.5%) reporting daily use, 126 reported (1.5%) weekly use, and 502 (5.8%) reported use less often than weekly. After adjusting for demographic factors, daily cannabis use compared with no use was associated with an increased likelihood of reporting two or more sexual partners in the previous year in both men (adjusted odds ratio 2.08, 95% confidence interval 1.11-3.89; P = 0.02) and women (2.58, 1.08-6.18; P = 0.03). Daily cannabis use was associated with reporting a diagnosis of a sexually transmissible infection in women but not men (7.19, 1.28-40.31; P = 0.02 and 1.45, 0.17-12.42; P = 0.74, respectively). Frequency of cannabis use was unrelated to sexual problems in women but daily use vs. no use was associated with increased reporting among men of an inability to reach orgasm (3.94, 1.71-9.07; P < 0.01), reaching orgasm too quickly (2.68, 1.41-5.08; P < 0.01), and too slowly (2.05, 1.02-4.12; P = 0.04).

CONCLUSIONS

Frequent cannabis use is associated with higher numbers of sexual partners for both men and women, and difficulties in men's ability to orgasm as desired.

Transitions to substance use and sexual intercourse among South african high school students

This study examined longitudinal patterns of initiating substance use and sexual intercourse among a sample of 1,143 high school students from a low-income township in Cape Town, South Africa. Longitudinal data on lifetime incidence of sexual intercourse and alcohol and marijuana use were collected semiannually from 2004 to 2006. Latent transition analysis (LTA) was used to test competing models of transitions to these behaviors. Participants were more likely to move from no risk behavior to substance use, rather than from no risk behavior to sexual intercourse. At all time points, the proportion of youth who had engaged in sexual intercourse but not substance use was very small. The study's limitations and directions for future research are discussed.
