Risky sex behavior and substance use among young adults

Youth sexual offending in Hong Kong: examining the role of self-control, risky sexual behaviors, and paraphilic interests

Introduction

Little is known about the nature and prevalence of sexual offending among youth in Hong Kong.

Methods

Testing self-control theory and sexual health risk factors (i.e., risky sexual behaviors [general and two subtypes] and paraphilic interests [general and 14 subtypes]), the prevalence of self-reported sexual offending behaviors (i.e., threat of sexual assault, penetrative sexual assault, and nonpenetrative sexual offense) was examined in a community-based sample of 863 young people (aged 17 to 20) in Hong Kong.

Results

In this study, men reported significantly higher levels of threat of sexual assault and of general and 12 subtypes of paraphilic interests than women; and women reported a significantly higher level of a specific paraphilic interest subtype (i.e., transvestic fetishism) than men. Logistic regressions found that, in general, a low level of self-control and high levels of risky sexual behaviors and paraphilic interests were important factors in the participants' likelihood of issuing threats of sexual assault and engaging in penetrative and nonpenetrative sexual assault.

Discussion

Important practical implications for reducing the tendency of young people to engage in sexual offending behavior can be derived from this study.

Inhibition of adult neurogenesis reduces avoidance behavior in male, but not female, mice subjected to early life adversity

Early life adversity (ELA) increases the risk of developing neuropsychiatric illnesses such as anxiety disorders. However, the mechanisms connecting these negative early life experiences to illness later in life remain unclear. In rodents, plasticity mechanisms, specifically adult neurogenesis in the ventral hippocampus, have been shown to be altered by ELA and important for buffering against detrimental stress-induced outcomes. The current study sought to explore whether adult neurogenesis contributes to ELA-induced changes in avoidance behavior. Using the GFAP-TK transgenic model, which allows for the inhibition of adult neurogenesis, and CD1 littermate controls, we subjected mice to an ELA paradigm of maternal separation and early weaning (MSEW) or control rearing. We found that mice with intact adult neurogenesis showed no behavioral changes in response to MSEW. After reducing adult neurogenesis, however, male mice previously subjected to MSEW had an unexpected decrease in avoidance behavior. This finding was not observed in female mice, suggesting that a sex difference exists in the role of adult-born neurons in buffering against ELA-induced changes in behavior. Taken together with the existing literature on ELA and avoidance behavior, this work suggests that strain differences exist in susceptibility to ELA and that adult-born neurons may play a role in regulating adaptive behavior.

Prenatal cocaine exposure, early cannabis use, and risky sexual behavior at age 25

BACKGROUND

Prior research on prenatal cocaine exposure (PCE) indicates that exposed children experience behavioral dysregulation resulting in risky adolescent behavior including earlier initiation of cannabis use and sexual intercourse. The goal of this study was to examine the long-term effects of PCE on adult sexual behavior.

METHODS

This is a prospective cohort study of the association between PCE and risky adult sexual behavior and sexually transmitted infections (STIs) in 202 young adults (mean age = 27, SD = 0.98 years). The sample was 55% female, 46% White, and 54% Black. Data from the prenatal, childhood, and adolescent phases of the study were used to delineate pathways from PCE to adult sexual behavior.

RESULTS

The most common risky sexual behavior was having sex while drunk or high (63%). One-third of the sample reported that they "almost always" had sex while drunk or high. We found evidence for an indirect pathway from PCE to adult sex while drunk or high via early cannabis initiation. There were no other effects of PCE on adult risky sexual behavior or on risk for STIs, after controlling for sex assigned at birth, race, age at sexual initiation, and family history of drug and alcohol problems.

CONCLUSIONS

Although PCE has been associated with earlier initiation of sex in prior studies, PCE was not directly associated with risky adult sex or history of STI. Exposed individuals were at greater risk of sex under the influence of alcohol or drugs via earlier initiation of cannabis use during adolescence.

Association of intimate partner violence and other risk factors with HIV infection among married women in India: evidence from National Family Health Survey 2015-16

Background

Human immunodeficiency virus (HIV) infection remains an important public health concern in many countries. It is fuelled by gender inequality and disparity, which has resulted in a fundamental violation of women’s human rights. This study aims to find out the association of intimate partner violence (IPV) and other risk factors with the prevalence of HIV infection among married women in India.

Methods

This study is based on data from the India National Family Health Survey (2015–16). Bivariate analysis has been performed to estimate the prevalence of HIV. Logistic regression analysis is conducted to find out the association between IPV, factors such as having alcoholic husband and lifetime partner, and HIV infection among currently married women.

Results

Married women who had faced physical, sexual, and emotional violence from their husbands/partners were almost twice more likely to have tested HIV positive compared to married women who did not face violence [OR: 2.14, CI: 1.08–4.50]. The odds of testing for HIV positive was significantly higher among the married women experiencing IPV and having alcoholic husband [OR: 4.48, CI: 1.87–10.70] than those who did not experience IPV and had non-alcoholic husband. The use of condom did not show any significant association with HIV infection. Again, having more than one lifetime partner had a positive association with HIV infection compared to those with one partner [OR: 2.45, CI: 1.21–4.16].

Conclusions

The study revealed that factors such as experiencing all types of IPV, having an alcoholic husband, increased number of lifetime partners, being sexually inactive, belonging to vulnerable social groups, and urban place of residence are important risk factors of HIV infection among married women in India. The results also suggest that gender-based violence and an alcoholic husband may represent a significant factor of HIV infection among married women and interventions should on focus such vulnerable populations.

Risky Sexual Behavior of Young Adults in Hong Kong: An Exploratory Study of Psychosocial Risk Factors

There is limited knowledge of the prevalence and nature of risky sexual behavior (RSB) among young adults in Hong Kong. This cross-sectional study explored the psychosocial risk factors of RSB with a sample of 1,171 Hong Kong university students (aged 18-40 years). Grounded in the theoretical propositions of several criminological theories (i.e., the theories of self-control, general strain, social learning, social control, and routine activity), engagement in three types of RSB (i.e., general, penetrative, and non-penetrative) was studied alongside a range of psychosocial risk factors. Relative to female participants, male participants reported significantly higher mean levels of general, penetrative, and non-penetrative RSB. Male participants also reported significantly higher mean levels of negative temperament, use of alcohol and other drugs, and paraphilic interests than female participants, who reported significantly higher mean levels of self-control and social bonds than their male counterparts. The results of multivariate analyses (i.e., OLS regressions) revealed that, to a large extent, the male and female participants shared a similar set of psychosocial risk factors (i.e., use of alcohol and other drugs, and paraphilic interest) for their involvement in general, penetrative, and non-penetrative RSB. Furthermore, a high level of negative temperament was significantly associated with penetrative RSB for both genders, while a high level of perceived neighborhood disorganization was found to be an important factor in the participation of females in general, penetrative, and non-penetrative RSB. The findings of this study may have important implications for practice in regard to reducing, if not entirely preventing, the tendency to engage in RSB.

Knowledge, Attitude, and Practices of Jimma Teacher Training College Students Toward Risky Sexual Behaviors, Jimma, Ethiopia

BACKGROUND

College students represent the huge section of teenagers in Ethiopia, and a growing number of them practice unsafe sex and hence face unwanted sexual health outcomes. Despite this, little has been explored about the college students' knowledge, attitude, and practice toward risky sexual behaviors (RSBs) in the study area. Therefore, this study aimed to assess the knowledge, attitude, and the practice of Jimma teacher training college students toward RSBs, Jimma town, southwest Ethiopia, in 2018.

METHODS

An institution-based quantitative cross-sectional study was conducted. Data were collected through a pretested, structured, and self-administered questionnaire. A total of 395 respondents were selected using a simple random sampling technique. The collected data were checked manually for completeness and consistency, entered into Epi-data, version 3.1, data entry software, and exported to SPSS, version 20, statistical software for analysis. Descriptive statistics were used to summarize the outcome and explanatory variables.

RESULTS

Among the total 360 respondents, 140 (38.9%) had poor knowledge of RSBs. The majority 78 (36.6%) of the respondents described radio as their main source of information about RSBs. More than three-quarters, 163 (76.6%) respondents define practicing oral and/or anal sex as RSBs and 194 (91%) reported sexually transmitted infections including HIV/AIDS as the main consequence of RSBs. This study also revealed 156 (43.4%) participants had an unfavorable attitude toward RSBs. 60 (16.7%) participants disagree with the idea that condoms prevent HIV/AIDS and nearly all respondents (340 [94.5%]) agreed homosexuality brings sexual risks. Among those who had sexual experience, 83 (32.4%) had 2 or more sexual partners, more than two-third (176 [68.8%]) had sexual practice after drinking alcohol, and 90 (35.1%) participants reported they did not use a condom when they had sex.

CONCLUSION

A significant percentage of the students have poor knowledge, attitude, and practice toward RSBs. Tesfaye Y, Agenagnew L. Knowledge, Attitude, and Practices of Jimma Teacher Training College Students Toward Risky Sexual Behaviors, Jimma, Ethiopia. Sex Med 2020;8:554-564.

Optimizing Assessment of Risk and Protection for Diverse Adolescent Outcomes: Do Risk and Protective Factors for Delinquency and Substance Use Also Predict Risky Sexual Behavior?

Assessments of youth risk and protective factors (RPFs) for substance use, delinquency, and violence have been used by communities to identify priorities and target them with prevention interventions. These same RPFs may also predict other youth problems. This study examined the strength and consistency of relationships of 41 ecological RPFs that predict antisocial behavior and substance use with sexual behavior outcomes in a sample of 2150 urban youth in 10th and 12th grade. After adjusting for controls, findings identify significant associations among the majority of community, school, family, peer, and individual risk factors, and family, peer, and individual protective factors, with sexual behavior outcomes, specifying unique associations among multiple factors with risky sex relative to both safe sex and not being sexually active. Prevention programming that targets common predictors for multiple problems may address a broad array of outcomes, including sexual health risk behaviors.

First Time Cannabis Use and Sexual Debut in U.S. High School Adolescents

PURPOSE

Use of illicit drugs by adolescents might facilitate or trigger other risky behaviors, including early sexual initiation (ESI), multiple partners, and unprotected sex. This study examines whether the age at which adolescents initiate cannabis use is associated with the age of their first sexual intercourse in the U.S. in 2015.

METHODS

A secondary analysis of data from the 2015 Youth Risk Behavior Surveillance Survey, a cross-sectional, nationally representative survey, was conducted (n = 7,664). Exposure of interest was age of initiation of cannabis use (never used cannabis, age 12 or younger, 13-14 years of age, and age 15 or older) and outcome was ESI (14 years old or younger). Unadjusted and adjusted odds ratios (OR) and their 95% confidence intervals were computed.

RESULTS

Prevalence of ESI was 15.3%. The proportion of cannabis use was 39.9%. Adolescents starting cannabis use before the age of 15 had higher adjusted odds of ESI (OR ranged 4.2-6.7). This association is modified by sex: while in boys using cannabis before 13 years, the OR is 9 (95% CI 5.2-15.6); in girls, it is 2.8 (95% CI 1.7-4.7).

CONCLUSIONS

Our findings suggest that there should be sex and drug education programs instituted before the age of 12 ideally, and no later than by age 15 since this time represents a critical period of initiating both behaviors.

The Impact of Traumatic Experiences on Risky Sexual Behaviors in Black and White Young Adult Women

BACKGROUND

Trauma exposure has been linked to risky sexual behavior (RSB), but few studies have examined the impact of distinct trauma types on RSB in one model or how the association with trauma and RSB may differ across race.

PURPOSE

The objective of the current study was to examine the contribution of trauma exposure types to RSB-substance-related RSB and partner-related RSB identified through factor analysis-in young Black and White adult women.

METHODS

We investigated the associations of multiple trauma types and RSB factor scores in participants from a general population sample of young adult female twins (n = 2,948). We examined the independent relationship between specific traumas and RSB, adjusting for substance use, psychopathology, and familial covariates. All pertinent constructs were coded positive only if they occurred before sexual debut.

RESULTS

In Black women, sexual abuse was significantly associated with substance-related and partner-related RSB, but retained significance only for partner-related RSB in a fully adjusted model. For White women, sexual abuse and physical abuse were associated with both RSB factors in the base and fully adjusted models. Witnessing injury or death was only associated with RSBs in base models. For both groups, initiating alcohol (for Black women), alcohol, or cannabis (for White women) before sexual debut (i.e., early exposure) was associated with the greatest increased odds of RSB.

CONCLUSIONS

Data highlight the contribution of prior sexual abuse to RSBs for both White and Black women, and of prior physical abuse to RSBs for White women. Findings have implications for intervention after physical and sexual abuse exposure to prevent RSB, and thus, potentially reduce sexually transmitted infection/human immunodeficiency virus infection and unintended pregnancy in young women.

Profiles of psychosocial adversity and their associations with health risk behaviors and mental health outcomes in young adults

Adverse psychosocial experiences operate simultaneously to affect mental health and behavior. The current study used mixture modeling to identify subgroups of young adults based on experiences of four types of psychosocial adversity and characterize their associations with depression, anxiety, world assumptions, substance use, and sexual risk behavior. Sexual assault, physical assault, and discrimination (interpersonal adversity) showed similar patterns within each group but diverged from neighborhood disadvantage in two groups. Groups characterized by higher interpersonal adversity reported the most negative health outcomes. Findings highlight variations in the co-occurrence of adverse experiences and differential links to risky health behaviors and mental health.

The Romantic Relationships of Adolescents With ADHD

OBJECTIVE

This study compared the romantic relationships of adolescents with and without ADHD with regard to romantic involvement, relationship content, and relationship quality.

METHOD

A community sample of 58 participants (30 ADHD, 28 Comparison), ages 13 to 18, completed questionnaires assessing various features of romantic relationships.

RESULTS

Adolescents with ADHD reported having more romantic partners than their typically developing (TD) peers. Females with ADHD were found to have shorter romantic relationships than TD adolescents while males with ADHD reported their age of first intercourse to be nearly 2 years sooner than TD peers. Irrespective of gender, adolescents with ADHD had nearly double the number of lifetime sexual partners. However, the romantic relationships of adolescents with and without ADHD did not differ on levels of aggression or relationship quality.

CONCLUSION

Given the outcomes associated with poor-quality romantic relationships, comprehensive assessments of adolescents with ADHD should include queries into their romantic relationships.

The role of young adult social bonds, substance problems, and sexual risk in pathways between adolescent substance use and midlife risky sexual behavior among urban African Americans

African Americans are disproportionately affected by HIV/AIDS and other sexually transmitted infections relative to other racial groups. Although substance use has been linked to risky sexual behavior, the understanding of how these associations develop over the life course remains limited, particularly the role of social bonds. This study uses structural equation modeling to examine pathways from adolescent substance use to young adult sexual risk, substance problems, and social bonds and then to midlife risky sexual behavior among African American men and women, controlling for childhood confounders. Data come from 4 assessments, 1 per developmental period, of a community-based urban African American cohort (N = 1,242) followed prospectively from ages 6 to 42 years. We found that greater adolescent substance use predicts greater young adult substance problems and increased risky sexual behavior, both of which in turn predict greater midlife sexual risk. Although greater adolescent substance use predicts fewer young adult social bonds for both genders, less young adult social bonding is unexpectedly associated with decreased midlife risky sexual behavior among women and not related for men. Substance use interventions among urban African American adolescents may have both immediate and long-term effects on decreasing sexual risk behaviors. Given the association between young adult social bonding and midlife risky sex among females, number of social bonds should not be used as a criterion for determining whom to screen for sexual risk among African American women. Future studies should explore other aspects of social bonding in linking substance use and risky sexual behavior over time. (PsycINFO Database Record

Does being drunk or high cause HIV sexual risk behavior? A systematic review of drug administration studies

HIV sexual risk behavior is broadly associated with substance use. Yet critical questions remain regarding the potential causal link between substance use (e.g., intoxication) and HIV sexual risk behavior. The present systematic review was designed to examine and synthesize the existing literature regarding the effects of substance administration on HIV sexual risk behavior. Randomized controlled experiments investigating substance administration and HIV sexual risk behavior (e.g., likelihood of condom use in a casual sex scenario) were included. Across five databases, 2750 titles/abstracts were examined and forty-three total peer reviewed published manuscripts qualified (few were multi-study manuscripts, and those details are outlined in the text). The majority of articles investigated the causal role of acute alcohol administration on HIV sexual risk behavior, although one article investigated the effects of acute THC administration, one the effects of acute cocaine administration, and two the effects of buspirone. The results of this review suggest a causal role in acute alcohol intoxication increasing HIV sexual risk decision-making. Although evidence is limited with other substances, cocaine administration also appears to increase sexual risk, while acute cannabis and buspirone maintenance may decrease sexual risk. In the case of alcohol intoxication, the pharmacological effects independently contribute to HIV sexual risk decision-making, and these effects are exacerbated by alcohol expectancies, increased arousal, and delay to condom availability. Comparisons across studies showed that cocaine led to greater self-reported sexual arousal than alcohol, potentially suggesting a different risk profile. HIV prevention measures should take these substance administration effects into account. Increasing the amount of freely and easily accessible condoms to the public may attenuate the influence of acute intoxication on HIV sexual risk decision-making.

Association Between Using Smartphone Dating Applications and Alcohol and Recreational Drug Use in Conjunction With Sexual Activities in College Students

BACKGROUND

The association between using smartphone dating applications (apps) and substance use in conjunction with sexual activities was only examined in homosexual men. This association was poorly understood in heterosexual samples.

OBJECTIVE

To explore the association between using dating apps and alcohol, and use of recreational drug in conjunction with sexual activities in college students.

DESIGN

666 students from four universities in Hong Kong were recruited in this cross-sectional study in the year 2015. Outcome measures included the use of dating apps, sexual history, and drug and alcohol use. Multivariable logistic regressions were employed.

RESULTS

The use of dating apps for more than 1 year was found to be associated with recreational drug use in conjunction with sexual activities (adjusted odds ratio: 7.23). Other risk factors of recreational drug use in conjunction with sexual activities included being bisexual/homosexual male, a smoker, and having one's first sexual intercourse at the age of less than 16 years. The use of dating apps was not a risk factor for alcohol consumption in conjunction with sexual activities. Risk factors for alcohol consumption in conjunction with sexual activities included being older, having monthly income more than HKD5,000, and a smoker. Furthermore, risk factors for alcohol consumption in conjunction with the last sexual activity included currently being in a dating relationship, a smoker, and having sex with a casual partner.

CONCLUSIONS

Using dating apps is an emerging risk factor of drug misuse. Interventions for practising safe sex and preventing drug use should be targeted at dating app users.

Age of First Arrest, Sex, and Drug Use as Correlates of Adult Risk Behaviors Among Rural Women in Jails

Incarcerated women frequently report initiation of substance use and sexual encounters at an early age, and often engage in high-risk drug use and sexual behaviors as adults. This study examined the timing of first sex, drug use, and arrest, as well as their unique influences on specific risky behaviors in adulthood, among a high-risk population of rural women recruited from jails. Ages of initiation were all positively and significantly correlated, and each independently increased the likelihood of several risky behaviors in adulthood. Implications are discussed for screening, intervention, and treatment targeting high-risk women and girls in rural areas, particularly within criminal justice settings.

Lifetime marijuana use and sexually transmitted infection history in a sample of Black college students

BACKGROUND

Sexually transmitted infections (STIs) and marijuana use are more prevalent in African Americans/Blacks (Blacks) than any other ethnicity in the United States. Given the significant health care costs and deleterious health correlates of using marijuana or contracting a STI, it is imperative to examine their association, especially in the vulnerable and underrepresented group of young adult Blacks.

PURPOSE

The current study examines the association between lifetime marijuana use on history of STI diagnosis in a sample of Black college students.

RESULTS

Approximately 81% of the 213 participants were female, with approximately 81% also being 21years of age or younger. Alcohol (88%) led the prevalence of substances ever used, followed by marijuana (75%), and cigarettes (57%). When including demographic and substance use covariates, lifetime marijuana use (AOR=2.51; 95% CIs, 1.01, 6.21) and age (AOR=2.72; 95% CIs, 1.32, 5.64) were associated with history of STI.

CONCLUSION

These findings will inform intervention and prevention methods used to reduce STI prevalence and marijuana use among Black young adults. Both epidemiological and biological foundations will be discussed.

Age of Sexual Debut and Cannabis Use in the United States

BACKGROUND

Understanding the interrelationships between risky health behaviors is critical for health promotion efforts. Conceptual frameworks for understanding substance misuse (e.g. stepping-stone models) have not yet widely incorporated other risky behaviors, including those related to sexual health.

OBJECTIVES

The goals of this study were to assess the relationship between early sexual debut and cannabis use, examine the role of licit substance use in this association, and evaluate differences by gender and race/ethnicity.

METHODS

Data came from the National Comorbidity Survey-Replication (NCS-R). Primary analysis was restricted to respondents who reported sexual debut at ≥12 years (n = 5,036). Age at sexual debut was categorized as early (<18 years), average (18 years) and late (>18 years). Logistic regression was used to assess the relationship between age at sexual debut and cannabis use. Interaction terms were used to evaluate effect modification by gender and race/ethnicity.

RESULTS

Later age of sexual debut was associated with lower odds of cannabis use relative to the average age of debut (AOR = 0.50, 95% CI = 0.37-0.66). For every year that respondents delayed their sexual debut, the relative odds of lifetime cannabis use declined by 17%. After accounting for alcohol and tobacco use the association between early sexual debut and cannabis was attenuated (AOR = 0.90, 95% CI = 0.68-1.20), while later age of debut remained protective (AOR = 0.57, 95% CI = 0.42-0.78). Results were generally consistent across race/ethnicity and gender.

CONCLUSIONS

Multifactorial intervention strategies targeting both sexual health and substance use may be warranted.

Racial-ethnic differences in sexual risk behaviors: The role of substance use

This research investigates the impact adolescent substance use has on adult sexual risk behaviors within racial-ethnic groups. Previous research has found support for this relationship, but often relies on concurrent measures of substance use and sexual risk behavior meaning that the causal direction of this relationship may be unclear. The data for this study come from the National Longitudinal Survey of Adolescent to Adult Health (Add Health), a nationally representative survey that followed respondents from adolescence in 1994 to adulthood in 2008. Results show that substance use correlates with sexual risk behavior, but the impact varies by race-ethnicity.

Health-Risk Behaviors and Dating Violence Victimization: An Examination of the Associated Risk Behaviors Among Detained Female Youth

There are many health-risk behaviors that may elevate the risk of adolescents engaging in teenage dating violence. The purpose of this investigation was to examine the health-risk behaviors that are associated with a sample of female juvenile offenders to identify the extent to which those behaviors contribute to dating violence. The survey assessed respondents' health-risk behaviors prior to incarceration, their perceptions of quality of life, post-incarceration expectations, psychosocial factors, and other social determinants. Results indicated youth exposure to dating violence, alcohol, drug, and risky sexual behaviors in the year prior to incarceration. These findings demonstrate the need to address teen dating violence with at-risk adolescents in addition to risky behaviors.

Compliance to Cell Phone-Based EMA Among Latino Youth in Outpatient Treatment

Outpatient treatment practices for adolescent substance users utilize retrospective self-report to monitor drug use. Cell phone-based ecological momentary assessment (CEMA) overcomes retrospective self-report biases and can enhance outpatient treatment, particularly among Latino adolescents, who have been understudied with regard to CEMA. This study explores compliance to text message-based CEMA with youth (n = 28; 93% Latino) in outpatient treatment. Participants were rotated through daily, random, and event-based CEMA strategies for 1-month periods. Overall compliance was high (>80%). Compliance decreased slightly over the study period and was less during random versus daily strategies and on days when alcohol use was retrospectively reported. Findings suggest that CEMA is a viable monitoring tool for Latino youth in outpatient treatment, but further study is needed to determine optimal CEMA strategies, monitoring time periods, and the appropriateness of CEMA for differing levels of substance use.

Influence of risk-taking health behaviours of adolescents on cervical cancer prevention: a Hungarian survey

An anonymous questionnaire survey was conducted among the Hungarian adolescents to establish their use of tobacco, alcohol and drugs in relation to sexual behaviours, knowledge of human papillomavirus (HPV) and cervical cancer, and beliefs and attitudes towards screening and vaccination. Results indicated that adolescent risk-taking health behaviours correlate with risky sexual behaviours. As risk-taking behaviours do not correlate with a better awareness of the risk associated with HPV infection, it is of crucial importance that HPV/cervical cancer preventing educational programmes shall be sensitive to this 'vulnerable' population and draw the attention of these adolescents to their increased risk of sexually transmitted diseases and undesired pregnancies. Well-designed behavioural change interventions may be effective when in addition to providing adolescents (both men and women) with clear information about the implications of an HPV infection, they also aim to improve safer sex behaviours: consistent condom usage, limiting the number of sex partners, as well as encouraging regular participation in gynaecological screenings and uptake of the HPV vaccine. As this study population demonstrated positive attitudes towards the primary and secondary prevention of cervical cancer, the free HPV vaccination for the 12-13-year-old girls in Autumn 2014 will hopefully increase the currently low uptake of the vaccine in Hungary.

The moderating effects of cannabis use and decision making on the relationship between conduct disorder and risky sexual behavior

Risky sexual behavior (RSB) is a current public health concern affecting adolescents and young adults. Conduct disorder, cannabis use, and decision-making (DM) ability are interrelated constructs that are relevant to RSB; however, there is little research on the association of DM and RSB. Participants were 79 cannabis users assessed through self-report measures of RSB and mental health and a timeline follow-back procedure for substance use. DM ability was assessed via the Iowa Gambling Task. We found that more conduct disorder symptoms accounted for unique variance in measures of overall RSB and an earlier initiation of oral sex, even when taking into account DM and cannabis use. Amount of cannabis use and DM ability moderated the relationships between number of conduct disorder symptoms and number of oral sex partners and age of initiation for vaginal sex. An increase in conduct disorder symptoms was associated with more oral sex partners when DM was poor and fewer partners when DM was better; however, this relationship was only present at higher levels of cannabis use. Furthermore, when DM was poor, more conduct disorder symptoms predicted a younger age of initiation of vaginal sex, with the age decreasing as amount of cannabis use increased. Determining how DM influences RSB may assist in the identification of novel treatment approaches to reduce engagement in RSB.

Factors associated with alcohol and/or drug use at sexual debut among sexually active university students: cross-sectional findings from Lebanon

Background

Sexual activity accompanied by substance use can impair youth decision-making and enhance risk-taking behaviors. Less is known, however, about the sexual values, perceptions and subsequent sexual practices of youth whose sexual debut occurs while using alcohol/drugs.

Methods

A cross-sectional anonymous online survey was conducted in April-August 2012 among undergraduate and graduate university students (aged 18 to 30) attending the 4th largest private university in Beirut. Pearson’s Chi-square and regression models were run using Stata/IC 10.0.

Results

940 university students had engaged in oral, anal and/or vaginal sex, of whom 10% admitted to having had consumed alcohol or taken drugs at sexual debut, a behavior that was more common in the males, less religious, non-Arabs, students living alone or who had lived abroad. Students who used alcohol/drugs at sexual debut were twice as likely to have: their first oral and vaginal sex with an unfamiliar partner [odds ratio (OR) = 2.6, 95% confidence interval (CI): (1.6, 4.2) and OR = 2.1 (1.2, 3.5), respectively], controlling for sex, nationality, current relationship status, living abroad after the age of 12, and spirituality. Students who had sex the first time while using alcohol/drugs were three times as likely to report having had 11 or more subsequent sexual partners versus one or two [OR = 3.0 (1.5-6.0)]; and almost twice as likely to ever engage in something sexual they did not want to do [OR = 1.7 (1.1, 2.8)]. Perceived peer pressure to have sex by a certain age [OR = 1.8 (1.1, 2.9)], and perceived peer norms to consume alcohol/drugs before sex [OR = 4.8 (2.3, 9.9)] were also strong correlates of having sex for the first time while using alcohol and/or drugs.

Conclusions

Findings stress the importance of sexuality education for youth, and the need to begin understanding the true interplay – beyond association - between youth sexual practices and substance use behaviors from a broader public health perspective.

[Study of determinants of unprotected sex in sailors of the Senegalese merchant navy]

Sailors are a mobile population travelling a lot and therefore being often exposed to casual sex. The aim of this study is to analyze the determinants of unprotected sex among sailors in Senegal. A descriptive and analytical study was conducted among sailors of the merchant navy. Data on knowledge, attitudes and practices were collected during a personal interview. A multivariate analysis was performed using a multiple logistic regression. A total of 400 sailors were interviewed, 57.9% had casual sex of whom 23.7% were not protected. Sexual intercourse without protection was more common among the uneducated (OR = 2.29 [1.23 to 5.99]) and married (OR = 2.29 [1.23-5.99]). Sailors who thought that using condom reduces pleasure during sexual intercourse (OR = 2.5 [1.2-5.1]) and those who consumed alcohol (OR = 5.4 [2.07-14.2]) were less protected during casual sex. Sexual contact is one of the main modes of transmission of HIV / AIDS. Sailors often have unprotected sex. Interventions using specific ways must be performed taking into account the mobility of these men who are often uneducated.

Risky sexual behavior in adolescent survivors of childhood cancer: a report from the Childhood Cancer Survivor Study

OBJECTIVE

To identify correlates of risky sexual behavior among adolescents surviving childhood cancer.

METHODS

The Child Health and Illness Profile-Adolescent Edition (CHIP-AE) was completed by 307 survivors of childhood cancer aged 15-20 years (M age at diagnosis 1.53 years; range 0-3.76). Univariate analyses were performed using χ² and Fisher's Exact tests, and multivariable logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI) for risky sexual behaviors.

RESULTS

Diagnosis of central nervous system cancer (OR = .13, 95% CI: .02-.96, p < .05), no history of beer or wine consumption (OR = .20, CI: .06-.68, p = .01), and fewer negative peer influences (OR = .28, CI: .09-.84, p = .02) associated with decreased likelihood of sexual intercourse. Good psychological health (scores ≥-1.5 SD on the CHIP-AE Emotional Discomfort scale) associated with decreased risk of early intercourse (OR = .19, CI: .05-.77, p = .02), whereas high parental education (≥ college degree) associated with decreased risk of multiple lifetime sexual partners (OR = .25, CI: .09-.72, p = .01). Increased time from diagnosis (OR = .27, CI: .10-.78, p = .02) and psychological health (OR = .09, CI: .02-.36, p < .01) associated with decreased risk of unprotected sex at last intercourse, whereas high parent education associated with increased risk (OR = 4.27, CI: 1.46-12.52, p = .01).

CONCLUSIONS

Risky sexual behavior in adolescents surviving childhood cancer is associated with cancer type, time since diagnosis, psychological health, alcohol use, and peer influences. Consideration of these factors may provide direction for future interventions designed to reduce adolescent sexual risk-taking.

High-risk cocktails and high-risk sex: examining the relation between alcohol mixed with energy drink consumption, sexual behavior, and drug use in college students

Alcohol mixed with energy drink (AmED) consumption has garnered considerable attention in the literature in recent years. Drinking AmED beverages has been associated with a host of negative outcomes. The present study sought to examine associations between AmED consumption and high-risk sexual behaviors in a sample of young adults. Participants (N=704; 59.9% female) completed an online survey assessing AmED consumption, other drug use, and sexual behavior. A total of 19.4% of the entire sample (and 28.8% of those who reported using alcohol) reported consuming AmED. Participants who reported consuming AmED were significantly more likely to report marijuana, cocaine, and ecstasy use. Those who reported consuming AmED also had increased odds of engaging in high-risk sexual behaviors, including unprotected sex, sex while under the influence of drugs, and sex after having too much to drink. Relationships between AmED consumption and sexual behavior remained significant after accounting for the influence of demographic factors and other substance use. Results add to the literature documenting negative consequences for AmED consumers, which may include alcohol dependence, binge drinking, and the potential for sexually transmitted infections via high-risk sexual behavior.

Underestimating protection and overestimating risk: examining descriptive normative perceptions and their association with drinking and sexual behaviors

Individuals who engage in risky sexual behavior face the possibility of experiencing negative consequences. One tenet of social learning theory is that individuals engage in behaviors partly based on observations or perceptions of others' engagement in those behaviors. The present study aimed to document these norms-behavior relationships for both risky and protective sexual behaviors, including alcohol-related sexual behavior. Gender was also examined as a possible moderator of the norms-behavior relationship. Undergraduate students (n = 759; 58.0% female) completed a Web-based survey, including various measures of drinking and sexual behavior. Results indicated that students underestimate sexual health-protective behaviors (e.g., condom use and birth control use) and overestimate the risky behaviors (e.g., frequency of drinking prior to sex, typical number of drinks prior to sex, and frequency of casual sex) of their same-sex peers. All norms were positively associated with behavior, with the exception of condom use. Furthermore, no gender differences were found when examining the relationship between normative perceptions and behavior. The present study adds to the existing literature on normative misperceptions as it indicates that college students overestimate risky sexual behavior while underestimating sexual health-protective behaviors. Implications for interventions using the social norm approach and future directions are discussed.

Risky health behavior among adolescents in the childhood cancer survivor study cohort

OBJECTIVE

To report the prevalence and comparison of cancer-linked health behaviors and identify risk factors associated with unhealthy behavior among adolescent siblings and cancer survivors.

METHODS

The Child Health and Illness Profile--Adolescent Edition (CHIP--AE) was completed by 307 survivors and 97 sibling controls 14-20 years of age.

RESULTS

Risky behavior ranged from 0.7% to 35.8% for survivors and 1.0% to 41.2% for siblings. Comparisons of sexual behavior, tobacco, alcohol, or illicit drug use utilizing continuous data revealed no differences between groups. Categorically, survivors were less likely to report past smokeless tobacco use or current use of beer/wine or binge drinking (p-values range from .01 to .04). Survivors with better mental health were at lower risk for poor behavioral outcomes.

CONCLUSIONS

Adolescent survivors engage in risky health behaviors at rates generally equivalent to their siblings. Aggressive health education efforts should be directed toward this high-risk population.

Attention deficit hyperactivity symptoms and risky sexual behavior in young adult women

BACKGROUND

This study was undertaken to assess the association between adult attention deficit/hyperactivity disorder (ADHD) symptoms and high-risk sexual behavior.

METHODS

This cross-sectional study interviewed 462 low-income women aged 18-30 years. We used the 18-item Adult ADHD Self-Report Scale (ASRS-v1.1) Symptom Checklist to assess ADHD symptoms. Risky sexual behaviors included sex before 15 years of age, risky sex partners in lifetime, number of sex partners in the last 12 months, condom use in the last 12 months, alcohol use before sex in the last 12 months, traded sex in lifetime, and diagnosed with sexually transmitted infection (STI) in lifetime.

RESULTS

Mean ADHD symptom score was 19.8 (SD±12.9), and summary index of all risky sexual behavior was 1.77 (SD±1.37). Using unadjusted odds ratios (OR), women who endorsed more ADHD symptoms reported engaging in more risky sexual behaviors of all types. However, when multivariable logistic regression was applied adjusting for various sociodemographic covariates, the adjusted ORs remained significant for having risky sex partners and having ≥3 sex partners in the prior 12 months. We observed some differences in risky sexual behavior between two domains of ADHD.

CONCLUSIONS

The ADHD symptom score appears to be associated with some risky sexual behaviors and deserves further attention. A brief ADHD screening can identify this high-risk group for timely evaluation and safe sex counseling.

Race differences in longitudinal associations between adolescent personal and peer marijuana use and adulthood sexually transmitted infection risk

To assess whether adolescent marijuana exposure represents a modifiable predictor of risk of sexually transmitted infections as adults, we used nationally representative, longitudinal data from Waves I (1994-1995, adolescence) and III (2001-2002, adulthood) of the National Longitudinal Study of Adolescent Health (N = 10,738) to examine racial and gender differences in associations between adolescent marijuana use, current use, and peer use and adulthood multiple partnerships, self-reported sexually transmitted infections, and biologically confirmed sexually transmitted infections. The risk of sexually transmitted infections as adults was predicted by adolescent marijuana use in all groups except Black women and by peer marijuana use among Black men. Adolescents who use or have friends who use marijuana constitute priority populations for sexually transmitted infection prevention.

Longitudinal associations between adolescent alcohol use and adulthood sexual risk behavior and sexually transmitted infection in the United States: assessment of differences by race

OBJECTIVES

We examined race differences in the longitudinal associations between adolescent alcohol use and adulthood sexually transmitted infection (STI) risk in the United States.

METHODS

We estimated multivariable logistic regression models using Waves I (1994-1995: adolescence) and III (2001-2002: young adulthood) of the National Longitudinal Study of Adolescent Health (n = 10 783) to estimate associations and assess differences between Whites and African Americans.

RESULTS

In adjusted analyses, adolescent alcohol indicators predicted adulthood inconsistent condom use for both races but were significantly stronger, more consistent predictors of elevated partnership levels for African Americans than Whites. Among African Americans but not Whites, self-reported STI was predicted by adolescent report of any prior use (adjusted odds ratio [AOR] = 1.47; 95% confidence interval [CI] = 1.00, 2.17) and past-year history of getting drunk (AOR = 1.53; 95% CI = 1.01, 2.32). Among Whites but not African Americans, biologically confirmed STI was predicted by adolescent report of past-year history of getting drunk (AOR = 1.68; 95% CI = 1.07, 2.63) and consistent drinking (AOR = 1.65; 95% CI = 1.03, 2.65).

CONCLUSIONS

African American and White adolescent drinkers are priority populations for STI prevention. Prevention of adolescent alcohol use may contribute to reductions in adulthood STI risk.

Age of Sexual Initiation, Psychiatric Symptoms, and Sexual Risk Behavior among Ecstasy and LSD Users in Porto Alegre, Brazil: A Preliminary Analysis

Ecstasy and LSD use is widespread in large Brazilian cities, but there is limited information on their use among young, middle-class, club goers in Brazil. We conducted standardized face-to-face interviews with 200 male and female ecstasy and/or LSD users, focusing on drug use and sexual history, current risk behaviors, and psychiatric symptomatology. Participants with early sexual debut (before 14) were more likely to report lifetime use of marijuana and powder and crack cocaine than those with later sexual initiation. Early sexual debut was associated with past year sexual risk behaviors, including having sex while high (Prevalence Ratio (PR)=1.3), having two or more sex partners (PR=1.3), as well as history of sexual abuse (PR=13.6). Depression and anxiety scores were similar by age of sexual initiation. The implications of these findings are discussed.

HIV-related risky practices among Brazilian young men, 2007

Behavioral surveillance surveys have been carried among military conscripts, in Brazil, since 1996. This paper presents the results of the 2007 survey and compares actual findings with those obtained in previous studies carried out in the period 1999-2002. The conscripts were selected with a two stage sampling stratified by geographical region. The study included a self-reported questionnaire and blood collection for HIV and syphilis testing. Data from 35,432 conscripts aged 17-20 years old were analyzed. The findings show a reduction in regular condom use, with fixed and casual partners, mainly among those with poor educational level. The proportion of conscripts that have sex with other men was maintained (3.2%), but the index of risky sexual behavioral showed worsening results in this group. Also, the HIV prevalence rate increased from 9 to 11.3 per 10,000 in 2007, though the increase was not statistically significant. In conclusion, the evidences found in this paper indicate the need of reformulate policy among young adults.

Effects of self-esteem and academic performance on adolescent decision-making: an examination of early sexual intercourse and illegal substance use

PURPOSE

To determine whether higher self-esteem and higher academic performance among youth reduce the likelihood of early sexual intercourse and illegal substance use.

METHODS

Using data from waves I-III of the National Longitudinal Study of Adolescent Health, this study used multivariate logistic regression, stratified by gender and controlling for known covariates, to examine relationships between self-esteem and academic performance and youth decision-making, specifically self-reported initiation of sexual intercourse and use of illegal substances. Self-esteem was constructed as an ascending scale of 10 Likert-scaled survey items. Academic performance was assessed using the most recent grades from English, Math, Science, and History.

RESULTS

Among virginal adolescents, higher self-esteem at baseline had no effect on sexual debut 1 year later. However, higher self-esteem at baseline among females corresponded with a significantly lower likelihood of illegal substance use 1 year later (OR, .96; p = .003). In terms of academic performance at baseline, girls averaging "A" grades as compared with girls averaging "C" grades or lower were significantly less likely to initiate sexual intercourse 1 year later (OR, .52; p = .004). Additionally among girls, being an "A" student or a "B" student was associated with lower odds of illegal substance use, compared with students who averaged "C" grades or lower (p < .01). Among young boys, self-esteem and academic performance were not significantly predictive of illegal substance use.

CONCLUSIONS

This study suggests that bolstering self-esteem and improving academic performance among young girls may have specific benefits in sexual decision-making and substance-related risk-taking.

Alcohol and sexual risk behavior among migrant female sex workers and male workers in districts with high in-migration from four high HIV prevalence states in India

This paper examines the association between alcohol use and sexual risk in two critical migrant populations living within the same geographical areas—migrant men and female sex-workers (FSWs). Data are drawn from two independent surveys of migrant FSWs and male workers in 14 districts of four high HIV prevalent Indian states. In the paper we have examined the independent effects of degree of mobility and alcohol use prior to sex on HIV risk behaviors. Nearly two-thirds of FSWs and a similar proportion of male migrant workers, as well as nine out of ten clients of FSWs consume alcohol. More than half of the FSWs and their clients consumed alcohol prior to sex. The practice of alcohol use prior to sex among both FSWs and their clients has a significant association with inconsistent condom use during paid as well as unpaid sex, and these effects are independent of degree of mobility. The results suggest a need for developing an in-depth understanding of the role of alcohol in accentuating HIV risk particularly among migrant populations who move frequently from one place another.

Adapting and applying a multiple domain model of condom use to Chinese college students

This study adapts a multiple domain model (MDM) to explain condom use among a sample of sexually active Chinese college students. A cross-sectional survey was conducted and structural equation modeling was used to test the proposed model. Preparatory behaviors, theory of reasoned action (TRA)/theory of planned behavior variables, impulsivity, length of relationship, and alcohol use were significant direct predictors of condom use. The results suggest that MDM can provide a better understanding of heterosexual condom use among Chinese youth, and help in the design of HIV-preventive and safer sex interventions in China.

Relationship between mental disorders/suicidality and three sexual behaviors: results from the National Comorbidity Survey Replication

The present study examined the relationship between sexual behaviors and mental disorders and suicidality in the National Comorbidity Survey Replication, a representative sample of adults ages 18 years and older (N = 5,692). The World Health Organization Composite International Diagnostic Interview was used to make DSM-IV based disorder diagnoses. Participants were also asked about suicidality and sexual behaviors. Multiple logistic regression analyses adjusted for sociodemographic variables were used to examine the relationships of three sexual behaviors (age of first intercourse, number of past year partners, and past year condom use) with 15 mental disorders (clustered into any mood, anxiety, substance use, and disruptive behavior groups) and suicidality (ideation and attempts). Compared to ages 15-17, those with age of first intercourse between 12 and 14 had increased rates of lifetime disruptive behavior, substance use, and any mental disorder, and suicidal ideation and attempts (adjusted odds ratio (AOR) range, 1.46-2.01). Those with age of first intercourse between ages 18-25 and 26-35 were at decreased likelihood of several lifetime disorder groups (AOR range, 0.19-0.81). Individuals who had two or more sexual partners in the past year had increased rates of all past year disorder groups examined (AOR range, 1.44-5.01). Never married participants who rarely/never used condoms were more likely than those who always used condoms to experience any mood, substance use, and any mental disorder, and suicide attempts (AOR range, 1.77-8.13). Future research should longitudinally examine these associations and account better for possible familial and personality confounders.

The relationship of perception of invincibility, demographics, and risk behaviors in adolescents of military parents

INTRODUCTION

The purpose of this research was to determine relationships among perceived invincibility, demographic variables, and risk behaviors in adolescents of active duty and retired military personnel.

METHOD

An instrument titled the Adolescent Invincibility Tool (AIT) was constructed and administered to a group of 125 adolescents of military parents. Correlation statistics were analyzed to determine variable relationships.

RESULTS

The AIT demonstrated reliability (Cronbach's alpha .88) in measuring invincibility in this sample. Participant characteristics and demographics were examined and revealed age, sex, ethnicity, and relocation frequency differences in relationship to the teen's level of perceived invincibility. Family relocation frequency and parent ranking/rating were significant variables for a military population. A significant positive relationship was identified between aggressive, delinquent behavior and invincibility; a negative correlation was demonstrated between worry and invincibility.

DISCUSSION

This study provided an opportunity to learn about unique influences related to being the teen of an active duty or retired military parent(s). Study findings indicate significant differences between military teens and national surveys in regard to risk taking and mental health indicators. Risk behaviors were found to occur at a lower frequency than the nationwide average, while depression occurred more frequently in this sample of military adolescents. Variations among teens of military parents in invincibility and worry scores provide direction for further study.

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.

Association of MDMA/ecstasy and other substance use with self-reported sexually transmitted diseases among college-aged adults: a national study

OBJECTIVES

MDMA/ecstasy use among college students has increased and reportedly leads to risky sexual behaviours. However, little is known about its association with sexually transmitted diseases (STDs). To evaluate this public health concern, this study examined the association between substance use (particularly MDMA) and self-reported STDs (chlamydia, gonorrhoea, herpes and syphilis) among college students and non-students aged 18-22 years (n=20,858).

STUDY DESIGN

A cross-sectional data analysis of a national survey.

METHODS

Data were drawn from the 2005-2006 National Surveys on Drug Use and Health; a nationally representative survey of non-institutionalized Americans. Self-reported STDs and substance use were assessed by the audio computer-assisted self-interviewing method. The association between MDMA use and STDs was determined while taking into account young adults' use of other substances, healthcare utilization and sociodemographic characteristics.

RESULTS

Overall, 2.1% of college students and 2.5% of non-students reported contracting an STD in the past year. MDMA use in the past year was not associated with STDs. Among non-students, onset of MDMA use before 18 years of age increased the odds of past-year STDs. In both groups, alcohol use, marijuana use, female gender and African American race increased the odds of both past-year and lifetime STDs. Additional analyses indicated that, regardless of college-attending status, greater odds of past-year STDs were noted among users of alcohol and drugs, and users of alcohol alone, but not among users of drugs alone.

CONCLUSIONS

Alcohol use is a robust correlate of STDs. Irrespective of college-attending status, young women and African Americans have a higher rate of STDs than young men and Whites.

Relations among religiousness, spirituality, and sexual practices

Although religiousness is commonly associated with limited sexual activity, little is known about spirituality's unique effect. Study aims involved measuring spirituality's unique affect on young adults' sexual practices (frequency of sex, number of sexual partners, and condom use) and determining whether spirituality adds significant increment over well-established predictors. Three hundred fifty-three (61% female) heterosexual young adults aged 17 to 29 completed this cross-sectional, self-report questionnaire study. Hierarchical regression analyses demonstrated spirituality is positively associated with participants' number of sexual partners and frequency of sex without a condom. Spirituality contributed to the prediction of participants' number of partners and condom use above and beyond the variance accounted for by religiousness, alcohol use, and impulsivity. A moderating effect for gender was found. Spirituality appears to have a unique and strong association with the sexual practices of young adults, particularly women, and should be assessed in future studies of young adults' sexual practices.

Positive urgency predicts illegal drug use and risky sexual behavior

There are several different personality traits that dispose individuals to engage in rash action. One such trait is positive urgency: the tendency to act rashly when experiencing extremely positive affect. This trait may be relevant for college student risky behavior, because it appears that a great deal of college student risky behavior is undertaken during periods of intensely positive mood states. To test this possibility, the authors conducted a longitudinal study designed to predict increases in risky sexual behavior and illegal drug use over the course of the first year of college (n=407). In a well-fitting structural model, positive urgency predicted increases in illegal drug use and risky sexual behavior, even after controlling for time 1 (T1) involvement in both risky behaviors, biological sex, and T1 scores on four other personality dispositions to rash action. The authors discuss the theoretical and practical implications of this finding.

Cognitive and psychomotor effects in males after smoking a combination of tobacco and cannabis containing up to 69 mg delta-9-tetrahydrocannabinol (THC)

RATIONALE

Delta(9)-Tetrahydrocannabinol (THC) is the main active constituent of cannabis. In recent years, the average THC content of some cannabis cigarettes has increased up to approximately 60 mg per cigarette (20% THC cigarettes). Acute cognitive and psychomotor effects of THC among recreational users after smoking cannabis cigarettes containing such high doses are unknown.

OBJECTIVES

The objective of this study was to study the dose-effect relationship between the THC dose contained in cannabis cigarettes and cognitive and psychomotor effects for THC doses up to 69.4 mg (23%).

MATERIALS AND METHODS

This double-blind, placebo-controlled, randomised, four-way cross-over study included 24 non-daily male cannabis users (two to nine cannabis cigarettes per month). Participants smoked four cannabis cigarettes containing 0, 29.3, 49.1 and 69.4 mg THC on four exposure days.

RESULTS

The THC dose in smoked cannabis was linearly associated with a slower response time in all tasks (simple reaction time, visuo-spatial selective attention, sustained attention, divided attention and short-term memory tasks) and motor control impairment in the motor control task. The number of errors increased significantly with increasing doses in the short-term memory and the sustained attention tasks. Some participants showed no impairment in motor control even at THC serum concentrations higher than 40 ng/mL. High feeling and drowsiness differed significantly between treatments.

CONCLUSIONS

Response time slowed down and motor control worsened, both linearly, with increasing THC doses. Consequently, cannabis with high THC concentrations may be a concern for public health and safety if cannabis smokers are unable to titrate to a high feeling corresponding to a desired plasma THC level.

Drug use and high-risk sexual behaviors among african american men who have sex with men and men who have sex with women

OBJECTIVES

We investigated covariates related to risky sexual behaviors among young African American men enrolled at historically Black colleges and universities (HBCUs).

METHODS

Analyses were based on data gathered from 1837 male freshmen enrolled at 34 HBCUs who participated in the 2001 HBCU Substance Use Survey. The covariates of risky sexual behavior assessed included condom nonuse, engaging in sexual activity with multiple partners, and history of a sexually transmitted disease.

RESULTS

Young Black men who had sex with men were more likely to engage in risky sexual behaviors than were young men who had sex with women. Two additional factors, early onset of sexual activity and consumption of alcohol or drugs before sexual activity, were independently associated with modestly higher odds of sexual risk behaviors.

CONCLUSIONS

Services focusing on prevention of sexually transmitted diseases should be provided to all male college students, regardless of the gender of their sexual partners. Such a general approach should also address drug and alcohol use before sexual activity.

An assessment of HIV/STI vulnerability and related sexual risk-taking in a nationally representative sample of young Croatian adults

Despite the recent increase in the number of HIV infections in Central and Eastern Europe, patterns of sexual behavior have not been extensively researched, particularly among young people. The aim of the present study was to provide a comprehensive assessment of HIV/AIDS-related vulnerability and sexual risk-taking among young adults in Croatia. Data were collected in 2005 using a nationally representative, multi-stage stratified probability sample (n = 1,093) of women and men aged 18-24 years. The focus in this article was on predictors of sexual risk-taking measured by a composite risky sexual behaviors scale. Using hierarchical regression models, we analyzed gendered effects of community, family, peer group, and individual level factors. For both men and women, peer pressure, sensation seeking, personal risk-assessment, behavioral intention, condom use at first sexual intercourse, and sexual victimization were significant predictors of sexual risk-taking behaviors. A number of predictors were gender-specific: sexual assertiveness and condom self-efficacy for women and parental monitoring, traditional morality, HIV knowledge, and talking about sex with partner for men. Documenting substantial prevalence of potentially risky sexual behaviors among young people in Croatia, the findings call for prevention and intervention efforts that should focus on individual capacity building for responsible sexual behavior.

Factors associated with sexual risk behaviour among young people in Ukraine

We used data from a behavioural survey of Ukrainian men and women aged 14-24 to examine the relationship between nine potential risk factors and two HIV risk outcomes: non-use of condom at last sex, and multiple sexual partnerships. Younger age at first sex was positively associated with both health risk outcomes, and condom non-use at first sex was associated with subsequent non-use of condoms at last sex. There were regional differences in frequencies of both HIV risk behaviours. Compared with those who reported living in the place they were born, not living permanently at the current place of residence was associated with a fivefold increase in the odds of multiple partnership for women but not for men. Alcohol and drug use were associated with higher odds of multiple partnership and the effect was greater among women than among men. The data analysed are cross-sectional so cannot establish causality. More studies are needed to confirm these results and investigate causal relationships between the possible risk factors and the two health risk behaviours.

Prevalence of and factors associated with extramarital sex among Nigerian men

This study used data on currently married and cohabiting men aged 15 to 64 years from the 2003 Nigeria Demographic and Health Survey to examine the prevalence of and factors associated with extramarital sex. The results show that 16% engaged in extramarital sex in the 12 months preceding the survey and had an average of 1.82 partners. The results also show statistically significant association between extramarital sex and ethnicity, religion, age, age at sexual debut, education, occupation, and place of residence. Based on the study results, it could be concluded that significant proportions of Nigerians are exposed to HIV infection through extramarital sex. A fundamental behavioral change expected in the era of HIV/AIDS is the inculcation of marital fidelity and emotional bonding between marital partners. The promotion of condom use among married couples should be intensified to protect women, a large number of whom are exposed to HIV infection from their spouses who engage in unprotected extramarital sex. And, because of gender-based power imbalances within the family, a large number of the women are unable to negotiate consistent condom use by their partners.
