Adolescent risk behavior and the influence of parents and education.

BACKGROUND: Adolescent involvement with alcohol, drugs, tobacco, sexual relationships, and gang violence begins at increasingly younger ages. Awareness of the dangers and consequences of risk-taking behavior has not had a profound or lasting impact on adolescent behavior, and there appears to be no relation between risk behavior and general knowledge concerning these topics. METHODS: Using paired anonymous questionnaires, we surveyed 215 seventh-grade students and their parents about their experience with and attitudes toward adolescent risk-taking behaviors. The results of each student questionnaire were compared with results of his or her own parents. The survey instrument contained questions concerning tobacco, alcohol, and drug use, sexual activity, gang membership, general knowledge concerning these topics, and parental guidance given. Data were analyzed using the chi2 test of significance. RESULTS: Parent and student recollection of issues discussed and guidance given differed widely, as did the students' understanding of their parents' guidance. Factors found to have a meaningful impact on the reduction of risk behavior in the adolescent population were (1) students perceiving a satisfactory relationship with their parents, and (2) parents successfully communicating their expectations regarding these behaviors to their children. CONCLUSIONS: Parental direction has a powerful effect on the reduction of risk behavior in young adolescents. A limited ability for abstract reasoning during early adolescence requires clear anticipatory guidance by parents and an active effort to maintain communication in the child-parent relationship.

Correlates of HIV risk behaviors in black and white San Francisco heterosexuals: the population-based AIDS in multiethnic neighborhoods (AMEN) study.

This study, the first random household probability sample of unmarried adults in an HIV epicenter, examined the prevalence and correlates of HIV risk behaviors among sexually active unmarried heterosexual white and black adults (n = 848) in San Francisco, California. Racial or gender differences were found in the HIV risk factors among the men and women in our sample. More whites (17% men, 15% women) than blacks (12% men, 5% women) reported they had ever used injection drugs. White women were more likely to report that they had a sexual partner who used injection drugs (17%) than white men (11%), black women (5%), or black men (4%). Also, men were more likely than women to have had two or more sexual partners in the past year without using condoms: 43% of white men compared to 34% of white women and 40% of black men compared to 24% of black women. Among all ethnic and gender groups, more than half of those at sexual risk for HIV infection reported never using condoms. Of those at risk, more black women (75%) than white women (53%) reported they never used condoms with their sexual partners within the past year. However, only slightly more black men (62%) than white men (60%) at sexual risk for HIV reported they never used condoms with their sexual partners during the past year. High levels of HIV risk behaviors were associated with low income, not having a primary sexual partner, less enjoyment of condoms, and greater barriers to using condoms. The results support the need for major intervention programs and social marketing campaigns to promote the use of condoms by enhancing enjoyment of and reducing barriers to condom use, especially among sexual partners of black women.

Early human immunodeficiency virus (HIV) infection in the HIV Network for Prevention Trials Vaccine Preparedness Cohort: risk behaviors, symptoms, and early plasma and genital tract virus load.

Risk behaviors, symptoms, and virologic characteristics were studied among 103 human immunodeficiency virus (HIV) seroconverters in vaccine preparedness cohorts during 1995-1998. Overall, 83% of subjects were men who had sex with men; most reported multiple risk episodes and symptoms (84%, > or =1 symptom) during seroconversion. Acute HIV was diagnosed in only 8 of 50 who sought medical care. Median initial pretreatment plasma virus load was 25,800 copies/mL (range, undetectable-262,000 copies/mL) a mean of 4 months after seroconversion, and 9.7% had nucleoside-associated mutations; none had multidrug resistance. Semen virus load was more variable, 1.3 log(10) lower and modestly correlated (r=.28; 95% confidence interval, 0.16-0.42) with plasma among untreated men. When the plasma RNA level was <5000 copies/mL, 32% of untreated men, 13% on nucleoside regimens, and 7% on protease inhibitor-containing regimens had detectable seminal RNA. Acute HIV was seldom diagnosed, representing missed opportunities for early treatment and prevention. Most subjects had several relatively stable virus loads before initiation of antiretrovirals, indicating feasibility of assessing HIV vaccines on virus set point in efficacy trials.

Reducing the sexual risk behaviors of HIV+ individuals: outcome of a randomized controlled trial.

Testing behavioral interventions to increase safer sex practices of HIV+ individuals has the potential to significantly reduce the number of new infections. This study evaluated a behavioral intervention designed to reduce the sexual risk behaviors of HIV+individuals. HIV+individuals (N = 387) who reported engaging in unprotected sex with HIV- or partners of unknown serostatus were randomly assigned to (a) a single counseling session targeting problem areas identified by the participant in 3 possible intervention domains (i.e., condom use, negotiation, disclosure); (b) a single-session comprehensive intervention that covered all 3 intervention domains; (c) the same comprehensive intervention, plus 2 monthly booster sessions; or (d) a 3-session diet and exercise attention-control condition. The median number of unprotected sex acts decreased from 14 at baseline to 6, 6, and 4 at 4-, 8-, and 12-month follow-ups, respectively. A repeated measures analysis of variance revealed a significant decrease in unprotected sex acts across all groups across time. A significant Group x Time interaction revealed that the comprehensive-with-boosters group had the most unprotected sex at 8-month follow-up as compared to the other 3 groups. These findings suggest that a brief intervention can result in large reductions in HIV transmission risks among HIV+individuals, but the relative benefit of one intervention approach over another remains unclear.

Use of postexposure prophylaxis against HIV infection following sexual exposure does not lead to increases in high-risk behavior.

BACKGROUND: The effectiveness of postexposure prophylaxis (PEP) following occupational exposure to HIV has prompted advocacy for PEP following sexual or drug-use exposures. OBJECTIVE: To evaluate the concern that the availability of PEP for sexual or drug-use exposures might result in behavioral disinhibition. DESIGN: Non-randomized trial of 397 adults with high-risk sexual or drug-use exposures within the prior 72 h. INTERVENTIONS: Antiretroviral medication for 4 weeks and five counseling sessions. MAIN OUTCOME MEASUREMENTS: Participants were followed for 12 months for repeat request for PEP and for changes compared with pre-enrollment in overall high-risk behavior and the acquisition of sexually transmitted diseases (STD) and HIV. RESULTS: After 12 months following receipt of PEP, the majority of participants (83%) did not request a repeat course of PEP. At 12 months after exposure, 73% of participants reported a decrease compared with baseline in the number of times they had performed high-risk sexual acts; 13% reported no change, and 14% had an increase. Most participants (85%) had no change in the incidence of STD; 8.5% had a decrease and 6.8% an increase. Three homosexual men seroconverted for HIV (none associated with the presenting exposure) for a rate of 1.2/100 person-year, equivalent to rates in San Francisco among all homosexual men. CONCLUSIONS: After receipt of PEP consisting of antiretroviral medication and behavioral counseling following a potential sexual exposure to HIV, most individuals do not increase high-risk behavior. Coupled with prior safety and feasibility data, this lack of behavioral disinhibition suggests that use of PEP should be routinely considered following high-risk sexual exposures.

Relationships between behavioral risk factors and dental care costs in a Japanese worksite.

PURPOSE: To identify the magnitude of dental care costs and examine the relationship between behavioral risk factors and dental care costs in a Japanese corporation. DESIGN: A one-time cross-sectional design was used with each employee as a unit of analysis. SETTING: The setting was a large Japanese corporation where Japan's standard health care insurance, including dental care coverage, was provided for all employees. SUBJECTS: A full-time employee population of 6543 was included. Seventy-six percent were men, and the majority were white-collar workers. MEASURES: Data were available on dental care costs and self-reported behavioral dental care risk, including smoking and oral self-care, obtained from the company's annual physical checkups in the 2000 fiscal year Dichotomous variables of expenditures for employees having no dental claims and those having high claims defined as 90th percentile or above were created. RESULTS: The dental care costs made up approximately 24.3% of the health care costs. Thirty-five percent of the employees were smokers. Employees who were at least 40 years old and employees who were women were associated with the likelihood of using dental care services (odds ratio [OR] = 1.622 and 0.783, respectively), and no behavioral risk was associated. The likelihood of incurring high dental care costs was associated with smoking when including all employees in addition to those who used any dental care services (OR = 1.315 and 1.386, respectively). CONCLUSIONS: This study suggests the relationships of smoking as well as age and sex to dental care costs in an employer setting. To provide a strong case for health promotion in Japan, future research should address critical issues such as reliable and valid risk measurement and the use of longitudinal designs and intervention studies.

Childhood peer rejection and aggression as predictors of adolescent girls' externalizing and health risk behaviors: a 6-year longitudinal study.

This 6-year longitudinal study examined girls' peer-nominated social preference and aggression in childhood as predictors of self- and parent-reported externalizing symptoms, substance use (i.e. cigarette, alcohol, and marijuana use), and sexual risk behavior in adolescence. Participants were 148 girls from diverse ethnic backgrounds, who were initially assessed in Grades 4-6 and again in Grades 10-12. Results supported a moderator model, indicating that social preference changed the nature of the association between childhood aggression and adolescent outcomes. When accompanied by peer rejection, aggressive behavior was moderately stable over time and significantly associated with adolescent girls' substance use and sexual risk behavior. However, under conditions of peer acceptance, no significant association between childhood aggression and adolescent outcomes emerged.

Teenagers' knowledge of the acquired immunodeficiency syndrome and associated risk behaviors.

Adolescents are now recognized as being at high risk for contracting the human immunodeficiency virus (HIV), the presumed cause of acquired immunodeficiency syndrome (AIDS). This article reports the findings of a survey that examined AIDS knowledge, risk behaviors, and informational sources for AIDS in a group of suburban New Jersey high school students (N = 152). This group had knowledge of HIV and its transmission, but results indicated that students also participated in behaviors considered "risky" for the transmission of HIV. These behaviors included unprotected sexual intercourse (40% of sexually active males) and sexual intercourse with multiple partners over a period of time (23% of sexually active males).

Temporal trends of HIV-related risk behavior among Brazilian military conscripts, 1997-2002.

PURPOSE: To present selected results of military conscript surveys related to HIV/AIDS, conducted in Brazil, 1997-2002. METHODS: Questionnaires including information on socio-demographic data, sexual behavior practices, sexually transmitted infections-related problems, and use of injecting drugs were completed by 30970 individuals, obtained through a 2-stage sampling. An index of sexual risk behavior was developed to take into account multiplicity of partners and irregularity of condom use. The HIV infection prevalence rate was estimated for 2002. Logistic regression was used to identify the most important determinants of HIV infection. RESULTS: The percentage of regular condom use increased from 38% (1997) to 49% (2002), and the index of sexual risk behavior decreased from 0.98 in 1997 to 0.87, in 2002. The HIV infection prevalence rate was 0.09%, in 2002, which remained unchanged since 1998 Riskier sexual practices among young men with incomplete education and among "men who have sex with men" were found as well as among the participants who reported at least one sexually transmitted infections - related problem. The most important predictor of HIV infection was to be positive for syphilis. CONCLUSIONS: The estimated value of the HIV infection prevalence supports the diagnosis of a concentrated HIV epidemic, in Brazil. Results indicate that particular attention needs to be paid for regional differentials, and for special subgroups, in Brazil.

Trends in injection risk behaviors in a sample of New York City injection drug users: 1992-1995.

OBJECTIVES: This study assessed the relation between year of recruitment into an AIDS prevention project and likelihood of engaging (yes/no) in injection risk behaviors. METHODS: In total, 834 injection drug users were recruited over a 44-month period (January 1992-August 1995) in New York City. Logistic regression was used to examine trends in three behaviors, across four successive annual cohorts: using needles/syringes that were previously used by another person, using injection supplies (e.g., cookers, cotton, rinse water) that had been previously used, and giving or lending of used needles/syringes to another person. RESULTS: Significant (p < .0001) decreasing trends occurred in two behaviors: giving or lending of used needles/syringes to another person and use of injection supplies that had been used by another person. Sample characteristics were generally consistent over time and did not obviate significant injection risk trends. CONCLUSIONS: Decreasing trends in injection risk behaviors could not be explained by changing sample characteristics. Even though some injectors report engaging in risky injection practices, the confluence of numerous AIDS prevention efforts in the 1990s has contributed to an overall reduction in the likelihood of such behaviors.

Drug-related HIV risk behaviors and cocaine preference among injection drug users in Los Angeles.

Based on a 1988-91 sample of 422 drug-using arrestees in Los Angeles, this study compares the drug-related risk behavior of users whose preferred injection drug is cocaine and users with a preference for heroin or no preference between the two drugs. Cocaine preference is unrelated to the likelihood of needle sharing overall, needle sharing with strangers, needle sharing at shooting galleries, and failure to use bleach as a needle disinfectant. In analyses restricted to users who reported needle sharing, the frequency of sharing is no more closely related to heroin injection frequency than to cocaine injection frequency. These results suggest that local preventive education programs do not need to address distinctive patterns of drug-related risk behavior among injection cocaine users and injection heroin users in Los Angeles.

Design, characteristics, and usefulness of state-based behavioral risk factor surveillance: 1981-87.

Since 1981, the Centers for Disease Control has collaborated with State health departments and the District of Columbia to conduct random digit-dialed telephone surveys of adults concerning their health practices and behaviors. This State-based surveillance system, which yields data needed in planning, initiating, and supporting health promotion and disease prevention programs, is described in this paper. Standard methods and questionnaires were used to assess the prevalence of personal health practices and behaviors related to the leading causes of death, including seatbelt use, high blood pressure control, physical activity, weight control, cigarette smoking, alcohol use, drinking and driving, and preventive health practices. Between 1981 and 1983, 29 States (includes the District of Columbia) conducted one-time telephone surveys. Beginning in 1984, most States began collecting data continuously throughout the year, completing approximately 100 interviews per month (range 50-250), with an average of 1,200 completed interviews per year (range 600-3,000). The raw data were weighted to the age, race, and sex distribution for each State from the 1980 census data. This weighting accounts for the underrepresentation of men, whites, and younger persons (18-24 years) in the telephone surveys and, for many health practices, provides prevalence estimates comparable with estimates obtained from household surveys. Nearly all (86 percent) of the States distributed selected survey results to other State agencies, local health departments, voluntary organizations, hospitals, universities, State legislators, and the press. The majority (60 percent) of States used information from the surveys to set State health objectives, prepare State health planning documents, and plan a variety of programs concerning antismoking, the prevention of chronic diseases, and health promotion. Further, nearly two-thirds (65 percent) used results to support legislation, primarily related to the use of tobacco and seatbelts. Most of the States (84 percent) reported that alternative sources for such data (prevalence of behavioral risk factors) were unavailable. Currently in 1988, over 40 State health departments are conducting telephone surveys as part of the Behavioral Risk Factor Surveillance System. This system has proved to be (a) flexible--it provides data on emerging public health problems, such as smokeless tobacco use and AIDS, (b) timely--it provides results within a few months after the data are collected, and (c) affordable--it operates at a fraction of the cost of comparable statewide in-person surveys. The system enables State public health agencies to continue to plan,initiate, and guide statewide health promotion and disease prevention programs and monitor their progress over time.

Racial disparities in sexual risk behaviors and drug use among older gay/bisexual and heterosexual men living with HIV/AIDS.

Adults over age 50 comprise 11% of yearly AIDS cases, yet little is known about their sexual risk behaviors and drug use following diagnosis with HIV/AIDS. The present questionnaire study examines potential racial differences in sexual risk and drug use behaviors among 59 HIV-infected gay/bisexual and heterosexual men over age 50 who were recruited from HIV-related organizations in New York City between 1996-1998. The majority (59%) of older men reported unprotected sex since diagnosis, and 36% had done so in the past six months. African-American gay/bisexual men (n=12) were significantly more likely than white gay/bisexual men (n=32) to report unprotected vaginal/anal sex in the past six months (67% versus 22%, p<0.01), since diagnosis (42% versus 9%, p<0.05), and to report a history of intravenous drug use (50% versus 3%, p<0.01), but did not differ from heterosexual African-American men (n=15). No differences were found in reports of unprotected oral sex or recent use of hard drugs (i.e., crack, cocaine, heroin). These findings suggest that interventions targeting older African-American men (both gay/bisexual and heterosexual) with HIV/AIDS are needed to reduce risk behaviors and prevent HIV transmission in this population.

Relationship of resources to emotional distress, somatic complaints, and high-risk behaviors in drug recovery and homeless minority women.

In a sample of 581 homeless or drug-abusing minority women, the relationship of self-esteem, sense of coherence, and support availability to emotional distress, somatic complaints, and high-risk behavior were investigated. Findings revealed that women who were high in self-esteem and stronger in sense of coherence reported significantly less emotional distress, and significantly fewer high-risk behaviors. In addition, women who were high in any of the three resources reported lower somatic complaints. Regression analyses revealed that coherence, self-esteem and support availability jointly accounted for 49% of the variance in emotional distress, 10% of the variance in high-risk activities, and 26% of the variance in somatic complaints. Implications for empowering women at risk for HIV infection are discussed.

Changes in network characteristics and HIV risk behavior among injection drug users.

Studies indicate that HIV risk behaviors vary greatly among injection drug users (IDUs). The source of such variation is often ascribed to individual differences, but much of it is due to how IDUs are grouped into social networks. Nevertheless, given the turbulent and uncertain lives led by many IDUs, it would not be surprising if their social networks changed substantially over time. We used data from a study of the social networks of IDUs in Chicago and Washington, DC, to examine changes in individual behavior and network characteristics over time. The results indicated few changes in standard network measures, such as density of ties or network size, over time. However, specific network change measures, that is, indicators of movement into and out of networks, showed significant movement of network members over time. Moreover, movement of members into a network significantly predicted a higher likelihood of risky injection drug use over time. We suggest that these movements are indicative of a lack of a stable resource base among IDU networks.

HIV knowledge and risk behaviors among Pakistani and Afghani drug users in Quetta, Pakistan.

Situated on the Pakistan-Afghan border, Quetta is home to growing numbers of Afghan refugees. We studied HIV knowledge and risk behaviors among Pakistani and Afghani drug users between July 2001 and November 2001. Of 959 drug users, all were male and the majority used heroin. Most were Pakistani (84.8%), 14.9% were Afghani, and 0.3% were Iranian. Relative to Pakistani drug users, a higher proportion of Afghanis reported no formal education, homelessness, and unemployment ( p <.001). Afghanis were more likely to have used an opiate as their first illicit drug (16% vs. 7%, p <.001), to have ever injected (18.8% vs. 12.3%, p =.04), to report needle sharing (72.2% vs. 48.2%, p =.08), or to report a drug user in their family ( p =.08). None of sexually active Afghanis had ever used a condom compared with 5.0% of the Pakistanis ( p =.01). Only 4.3% of Afghans had ever heard of HIV/AIDS compared with 18.3% of Pakistanis ( p <.001). Extremely low levels of HIV/AIDS awareness and high HIV risk behaviors were evident among drug users in Quetta, among whom Afghanis were especially vulnerable. Interventions to prevent transition to injection, needle exchange, and drug treatment are urgently required to prevent blood-borne infections.

Crack cocaine use and high-risk behaviors among sexually active black adolescents.

The recent spread of crack cocaine use among inner-city teenagers has been accompanied by dramatic increases in juvenile delinquency and sexually transmitted diseases (STDs) among teenagers. This study examined the prevalence of five factors which promote STDs, including human immunodeficiency virus (HIV), among a sample of sexually active black adolescent crack users and non-users from the San Francisco Bay Area. Significant differences were observed between these groups with respect to history of engaging in sexual intercourse under the influence of drugs or alcohol, exchanging sexual favors for drugs or money, condom use in the most recent sexual encounter, and having five or more sexual partners in the last year. Approximately 63% of all respondents reported engaging in at least one of these risk behaviors. In multiple logistic regression analysis, reporting one or more of these STD/HIV risk behaviors was significantly associated with crack use and having one or more relatives who used drugs. Intervention efforts need to address both individual and environmental risk factors in order to reduce teens' risk for STDs, including HIV.
