Situational factors associated with AIDS risk behavior lapses and coping strategies used by gay men who successfully avoid lapses.

While most gay men have reduced behavior practices at high risk for HIV infection, there is growing evidence that many also lapse to unsafe sex. This study examined situational factors related to risk behavior lapses as well as coping strategies used by men who successfully resist lapse urges. A convenience sample of 470 men patronizing gay bars or attending social organization meetings in four cities was surveyed. Forty-five percent of men were classified as "lapsers" (those who had had unprotected anal intercourse in the previous 6 months) and 24% were classified as "resisters" (those who successfully resisted urges to engage in this behavior). All provided information concerning the importance of factors related to the most recent occurrence of either unsafe sex or resisting unsafe urges. Most episodes of unsafe sex occurred outside monogamous relationships and with partners of unknown HIV serostatus, although simply inquiring about partner serostatus was relatively common. Lapsers rated affectionate feelings and wishing to please a partner as well as spontaneity of unsafe sex as the most important situational factors surrounding high-risk behavior. Resisters of unsafe sex urges reported active cognitive self-guidance, experience in safe sex, and recall of both AIDS fears and safety benefits as their most important coping strategies. Gay men who continue high-risk behavior may be overrelying on partner reports of negative serostatus. Lapse prevention approaches tailored to situations that create increased risk vulnerability must be developed. Teaching skills already used by men who successfully resist unsafe sex urges might be one approach.

Youth risk behavior surveillance--United States, 2001.

PROBLEM/CONDITION: Priority health-risk behaviors, which contribute to the leading causes of mortality and morbidity among youth and adults, often are established during youth, extend into adulthood, are interrelated, and are preventable. REPORTING PERIOD COVERED: This report covers data during February-December 2001. DESCRIPTION OF SYSTEM: The Youth Risk Behavior Surveillance System (YRBSS) monitors six categories of priority health-risk behaviors among youth and young adults; these behaviors contribute to unintentional injuries and violence; tobacco use; alcohol and other drug use; sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) infection; unhealthy dietary behaviors; and physical inactivity. The YRBSS includes a national school-based survey conducted by CDC as well as state, territorial, and local school-based surveys conducted by education and health agencies. This report summarizes results from the national survey, 34 state surveys, and 18 local surveys conducted among students in grades 9-12 during February-December 2001. RESULTS: In the United States, approximately three fourths of all deaths among persons aged 10-24 years result from only four causes: motor-vehicle crashes, other unintentional injuries, homicide, and suicide. Results from the 2001 national Youth Risk Behavior Survey demonstrated that numerous high school students engage in behaviors that increase their likelihood of death from these four causes: 14.1% had rarely or never worn a seat belt during the 30 days preceding the survey; 30.7% had ridden with a driver who had been drinking alcohol; 17.4% had carried a weapon during the 30 days preceding the survey; 47.1% had drunk alcohol during the 30 days preceding the survey; 23.9% had used marijuana during the 30 days preceding the survey; and 8.8% had attempted suicide during the 12 months preceding the survey. Substantial morbidity and social problems among young persons also result from unintended pregnancies and STDs, including HIV infection. In 2001, 45.6% of high school students had ever had sexual intercourse; 42.1% of sexually active students had not used a condom at last sexual intercourse; and 2.3% had ever injected an illegal drug. Two thirds of all deaths among persons aged > or = 25 years result from only two causes: cardiovascular disease and cancer. The majority of risk behaviors associated with these two causes of death are initiated during adolescence. In 2001, 28.5% of high school students had smoked cigarettes during the 30 days preceding the survey; 78.6% had not eaten > or = 5 servings per day of fruits and vegetables during the 7 days preceding the survey; 10.5% were overweight; and 67.8% did not attend physical education class daily. PUBLIC HEALTH ACTIONS: Health and education officials at national, state, and local levels are using these YRBSS data to analyze and improve policies and programs to reduce priority health-risk behaviors among youth. The YRBSS data also are being used to measure progress toward achieving 16 national health objectives for 2010 and 3 of the 10 leading health indicators.

Behavioral risk factor and preventive health care practice survey of immigrants in the emergency department.

OBJECTIVE: To compare the demographic profiles, behavioral risk factors, and preventive health care practices of adult immigrant and non-immigrant patients while considering the effects of various socioeconomic variables. METHODS: This was a prospective survey administered at a large urban emergency department in New York City. Study subjects were adult immigrant patients presenting in an eight-week period in 1998. One non-immigrant control patient was recruited concurrently with every two immigrant patients. Differences between immigrants and non-immigrants were evaluated using the chi-square test. Multivariate logistic regression models were used to adjust for confounding variables. RESULTS: Eight hundred sixty-nine immigrant patients from 80 countries and 354 non-immigrant patients completed surveys. Immigrants were more likely not to have reached high school (28.9% vs 8.5%; p < 0.001), to have annual family incomes less than $20,000 (73.8% vs 64.5%; p < 0.01), and to have no health coverage (51.7% vs 30.8%; p < 0.001). Immigrant women were more likely never to have had a Papanicolaou test (16.1% vs 1.4%; OR 11.24, 95% CI = 2.70 to 46.8) and never to have performed a self-breast examination (20.8% vs 7.5%; OR 2.03, 95% CI = 1.29 to 3.20). Immigrants were more likely not to use condoms (63.4% vs 42.8%; OR 1.61, 95% CI = 1.20 to 2.15) and never to have visited a dentist (21.2% vs 7.8; OR 2.54, 95% CI = 1.60 to 4.04). Immigrants were more likely never to have received a purified protein derivative (PPD) skin test (30.3% vs 9.1%; OR 3.85, 95% CI = 2.56 to 5.80) and never to have received a tetanus immunization (48.1% vs 13.5%; OR 3.09, 95% CI = 2.17 to 4.42). These differences were independent of age, gender, marital status, employment, education, income, and health insurance status. When analyzing the immigrant group alone, region of origin, length of time in the United States, and English ability were significant independent predictors of higher-risk behavioral profiles and poor preventive health care practices. CONCLUSIONS: Differences exist between the socioeconomic profiles, behavioral risk profiles, and preventive health care practices of immigrant and non-immigrant patients presenting to a large inner-city municipal emergency department. Different populations within a heterogeneous group of immigrants have distinct health risks and public health needs.

HIV risk behavior, street outreach, and condom use in eight high-risk populations.

In this paper we examine risk behavior, exposure to street outreach, and condom use in samples of injecting drug users (IDUs) and high-risk youth. We used systematic sampling methods to produce representative samples of injecting drug users IDUs (five sites) and high-risk youth (three sites). The populations surveyed engaged in high levels of sexual risk behavior: 20% to 46% reported two or more sex partners in the last month. The majority (62% to 97%) knew someone infected with HIV. Condom use rates approached national health promotion goals for nonsteady partners but not for steady or main partners. Having a condom at time of interview was the most consistent predictor of condom use at last intercourse. Many of the respondents have been in contact with street outreach programs and many acknowledged some personal risk for HIV infection. However, most of the injecting drug users and high-risk youth interviewed (and their sex partners) were still at risk through unprotected sex.

School attendance, health-risk behaviors, and self-esteem in adolescents applying for working papers.

Since health-risk behaviors are often encountered in clusters among adolescents, it was hypothesized that adolescents with poor school attendance would be associated with more health-risk behaviors (e.g., substance use, violence) than those who attend school regularly. This study assessed the relationship between poor school attendance and health-risk behaviors, and described health-risk behaviors and self-esteem among adolescents seeking employment. In this cross-sectional study, school attendance (poor vs. regular attendance) was related to health-risk behaviors by asking 122 subjects seen at a New York City Working Papers Clinic to complete both a 72-item questionnaire about their health-risk behaviors and the 58-item Coopersmith Self-Esteem School Form Inventory. Chi-square and Fisher's Exact Tests were performed. The poor and regular attenders of school differed significantly in only 5 out of 44 items pertaining to health-risk behaviors. Self-esteem measures for the two groups did not differ from one another or from national norms. In this sample, depression "in general" (global) and "at home," but not "at school," were associated significantly with suicidal thoughts/attempts and serious past life events (e.g. family conflict, sexual abuse). There were no significant associations between depression or self-esteem and illicit substance or alcohol use. We found few associations between poor school attendance and health-risk behaviors in this sample of employment-seeking adolescents. The poor and regular attenders of school were similar in most aspects of their health-risk behaviors and self-esteem.

A descriptive study of youth risk behavior in urban and rural secondary school students in El Salvador.

BACKGROUND: Adolescence is an important stage of life for establishing healthy behaviors, attitudes, and lifestyles that contribute to current and future health. Health risk behavior is one indicator of health of young people that may serve both as a measure of health over time as well as a target for health policies and programs. This study examined the prevalence and distribution of youth health risk behaviors from five risk behavior domains-aggression, victimization, depression and suicidal ideation, substance use, and sexual behaviors-among public secondary school students in central El Salvador. METHODS: We employed a multi-stage sampling design in which school districts, schools, and classrooms were randomly selected. Data were collected using a self-administered questionnaire based on the United States Center for Disease Control and Prevention's Youth Risk Behavior Survey. Sixteen schools and 982 students aged 12-20 years participated in the study. RESULTS: Health risk behaviors with highest prevalence rates included: engagement in physical fight (32.1%); threatened/injured with a weapon (19.9%); feelings of sadness/hopelessness (32.2%); current cigarette use (13.6%); and no condom use at last sexual intercourse (69.1%). Urban and male students reported statistically significant higher prevalence of most youth risk behaviors; female students reported statistically significant higher prevalence of feelings of sadness/hopelessness (35.6%), suicidal ideation (17.9%) and, among the sexually experienced, forced sexual intercourse (20.6%). CONCLUSION: A high percentage of Salvadoran adolescents in this sample engaged in health risk behaviors, warranting enhanced adolescent health promotion strategies. Future health promotion efforts should target: the young age of sexual intercourse as well as low condom use among students, the higher prevalence of risk behaviors among urban students, and the important gender differences in risk behaviors, including the higher prevalence of reported feelings of sadness, suicidal ideation and forced sexual intercourse among females and higher sexual intercourse and substance use among males. Relevance of findings within the Salvadoran and the cross-national context and implications for health promotion efforts are discussed.

Surveillance for health behaviors of American Indians and Alaska Natives. Findings from the Behavioral Risk Factor Surveillance System, 1997-2000.

PROBLEM/CONDITION: In the United States, disparities in risks for chronic disease (e.g., diabetes, cardiovascular disease, and cancer) and human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) are evident among American Indians and Alaska Natives (AI/ANs) and other groups. This report summarizes findings from the 1997-2000 Behavioral Risk Factor Surveillance System (BRFSS) for health-status indicators, health-risk behaviors, and HIV testing and perceived risk for HIV infection among AI/ANs, compared with other racial/ethnic groups in five regions of the United States. REPORTING PERIOD COVERED: 1997-2000. DESCRIPTION OF SYSTEM: BRFSS is a state-based telephone survey of the civilian, noninstitutionalized, adult (i.e., persons aged > or =18 years) population. For this report, responses from the 36 states covered by the Indian Health Service administrative areas were analyzed. RESULTS: Region and sex-specific variations occurred in the prevalence of high-risk behaviors and health-status indicators. For example, the prevalence of current cigarette smoking ranged from 21.2% in the Southwest to 44.1% in the Northern Plains, and the awareness of diabetes was lower in Alaska than in other regions. Men were more likely than women to report binge drinking and drinking and driving. For the majority of health behaviors and status measures, AI/ANs were more likely than respondents of other racial/ethnic groups to be at increased risk. For example, AI/ANs were more likely than respondents of other racial/ethnic groups to report obesity (23.9% versus 18.7%) and no leisure-time physical activity (32.5% versus 27.5%). INTERPRETATION: The 1997-2000 BRFSS data demonstrate that health behaviors vary regionally among AI/ANs and by sex. The data also reveal disparities in health behaviors between AI/ANs and other racial/ethnic groups. The reasons for these differences by region and sex, and for the racial/ethnic disparities, are subjects for further study. However, such patterns should be monitored through continued surveillance, and the data should be used to guide prevention and research activities. For example, states with substantial AI/AN populations, and certain tribes, have successfully used BRFSS data to develop and monitor diabetes and tobacco prevention and control programs. PUBLIC HEALTH ACTIONS: Federal and state agencies, tribes, Indian health boards, and urban Indian health centers will continue to use BRFSS data to develop and guide public health programs and policies. The BRFSS data will also be used to monitor progress in eliminating racial and ethnic health disparities. Regional Indian health boards, tribal epidemiology centers, and Indian Health Service Area Offices can use the findings of this report to prioritize interventions to prevent specific health problems in their geographic areas. Moreover, tribes and other institutions that promote AI/AN health care can use the report to document health needs when applying for resources.

The clustering of risk behaviors among Caribbean youth.

OBJECTIVE: To examine the relationships among risk behaviors for Caribbean youth; and to determine the correlations between initiation of sexual activity and other risk behaviors. METHODS: The associations between cigarette smoking, alcohol and marijuana use, early initiation of sexual intercourse, involvement in violence and delinquency were examined using odds ratios on data from the Caribbean Youth Health Survey (n = 15, 695). Survival analysis was then used to determine the association between initiation of sexual activity and the risk behaviors. FINDINGS: There were statistically significant relationships between all pairs of risk behaviors for both male and female adolescents. Even though more males than females had engaged in each of the behaviors, the strengths of association were higher for females. From survival analysis, initiation of sexual activity was associated with gang involvement and weapon carrying among young adolescents and even more risk behaviors among the older adolescents. CONCLUSION: Health compromising behaviors cluster among Caribbean youth with associations being stronger for females. Initiating sexual activity was a predictor of other risk behaviors with the likelihood increasing among older adolescents and females.

Multiple risk behavior and injury: an international analysis of young people.

BACKGROUND: Multiple risk behavior plays an important role in the social etiology of youth injury, yet the consistency of this observation has not been examined multinationally. OBJECTIVE: To examine reports from young people in 12 countries, by country, age group, sex, and injury type, to quantify the strength and consistency of this association. SETTING: World Health Organization collaborative cross-national survey of health behavior in school-aged children. PARTICIPANTS: A multinational representative sample of 49 461 students aged 11, 13, and 15 years. MAIN EXPOSURE MEASURES: Additive score consisting of counts of self-reported health risk behaviors: smoking, drinking, nonuse of seat belts, bullying, excess time with friends, alienation at school and from parents, truancy, and an unusually poor diet. MAIN OUTCOME MEASURE: Self-report of a medically treated injury. RESULTS: Strong gradients in risk for injury were observed according to the numbers of risk behaviors reported. Overall, youth reporting the largest number (> or =5 health risk behaviors) experienced injury rates that were 2.46 times higher (95% confidence interval, 2.27-2.67) than those reporting no risk behaviors (adjusted odds ratios for 0 to > or =5 reported behaviors: 1.00, 1.22, 1.48, 1.73, 1.98, and 2.46, respectively; P<.001 for trend). Similar gradients in risk for injury were observed among youth in all 12 countries and within all demographic subgroups. Risk gradients were especially pronounced for nonsports, fighting-related, and severe injuries. CONCLUSIONS: Gradients in risk for youth injury increased in association with numbers of risk behaviors reported in every country examined. This cross-cultural finding indicates that the issue of multiple risk behavior, as assessed via an additive score, merits attention as an etiological construct. This concept may be useful in future injury control research and prevention efforts conducted among populations of young people.

Current smoking trends in the United States. The 1981-1983 behavioral risk factor surveys.

Based on the aggregate of behavioral risk factor surveys, almost one third of adults were smokers in 1982. Overall, significantly fewer Hispanics smoked compared with whites or blacks. Among young adults, however, the rate of smoking was highest among whites compared with blacks and Hispanics. Compared with nonsmokers, smokers--especially young women--had higher rates of other risk behaviors, including alcohol misuse and lack of seat-belt use. Since 1965, the rate of decline of smoking among women has not been as great as that among men, due in part to the high rate--more than 40%--of smoking among young white women. Despite continued decrease in the overall proportion of smokers, the high rate among young women emphasizes the need for continued efforts toward prevention and cessation, before the well-documented health consequences develop.

HIV risk behavior among Peace Corps Volunteers.

OBJECTIVE: To describe HIV risk behaviors among Peace Corps Volunteers (PCV) and to examine correlates of sexual risk behaviors. METHOD: Cross-sectional data were collected from 1242 randomly selected PCV serving in 28 countries in 1991. PCV reported the frequency of specific risk behaviors in self-administered questionnaires, which were completed anonymously and returned to the Centers for Disease Control and Prevention. RESULTS: Non-sexual HIV risk behaviors were rarely reported by PCV. Sixty-one per cent of the 1080 PCV who answered questions about sexual behavior during their Peace Corps service reported having at least one sex partner. Sixty per cent of PCV had another PCV partner, 39% had a host-country national partner, and 29% had a non-PCV expatriate partner. Overall, less than one-third (32%) of unmarried PCV used condoms during every episode of sexual intercourse; more frequent use was reported in relationships with non-steady and (for male PCV) host-country national partners. Among male PCV, condom use was positively related to lower alcohol use and the belief that HIV was a problem in the host country. Female PCV reporting more condom use with male partners were younger and had fewer partners than those reporting less use. CONCLUSION: These data indicate that PCV are at risk for acquiring HIV through unprotected vaginal intercourse. All persons who become sexually active with new partners while travelling or living abroad should be encouraged to use condoms consistently.

Social influences on health-risk behaviors among minority middle school students.

PURPOSE: To determine whether parent social influences are associated with health-risk behaviors more than peer social influences among young minority adolescents. METHODS: We conducted a cross-sectional survey of seventh-grade students in a public urban magnet middle school using a survey instrument adapted from the Centers for Disease Control and Prevention Youth Risk Behavior Survey. The sample consisted of all seventh-grade students in the school, and the survey was part of a needs assessment for a school-based health education program. We measured four health-risk behaviors: use of (a) tobacco, (b) alcohol, (c) onset of sexual activity, and (d) marijuana use; and five social influences: (a) parent disapproval of health-risk behaviors, (b) parent modeling of health-risk behaviors, (c) parent monitoring of health-risks, (d) peer disapproval of health risks, and (e) peer modeling of health-risk behaviors. The analyses included measures of the prevalence of health-risk behaviors, bivariate analyses to evaluate relationships between health-risk behaviors and social influences, and regressions analyses to determine the independent associations of the social influences with the four health-risk behaviors. RESULTS: Twenty percent of respondents reported using tobacco, over 50% used alcohol in the past year, 13.3% were sexually active, and 12% reported marijuana use. Parent influences were associated with differences in alcohol use, whereas peer influences were associated with differences in all measured health-risk behaviors: tobacco and alcohol use, sexual activity, and marijuana use. Regression analyses demonstrated that peer social influences were the only measures independently associated with abstinence from tobacco (p < .05), alcohol (p < .01), sexual activity (p < .05), and marijuana use (p < .05). In all analyses, peers emerged as the most consistent social influence on health-risk behavior. CONCLUSION: This study suggests peers and peer group behavior may be better predictors of adolescent health-risk behaviors than parental social influences among young adolescents.

A comparison of HIV risk behaviors between new and long-term injection drug users.

The purpose of this study was to characterize the injection and sexual risk behaviors of a cohort of active drug injectors who have initiated injection within the past 4 years and to compare their behaviors with the risk behaviors of long-term injectors who have been injecting drugs since 1984. A stratified, network-based sample was used to recruit injection drug users from the streets in Miami-Dade, Florida. After screening for eligibility, which included a urine test to confirm current drug use, participants were administered a structured questionnaire that included basic demographic information, drug-use history, and HIV risk behavior practices. Both injector groups displayed a high level of HIV injection risk behavior. Although new initiates into injection demonstrated lower risk behavior than long-term injectors at the first injection episode, the current risk behavior between new and long-term injectors is similar.

Adolescent peer crowd affiliation: linkages with health-risk behaviors and close friendships.

OBJECTIVE: To examine adolescents' peer crowd affiliation and its linkages with health-risk behaviors, their friends' health-risk behaviors, the presence of close friends in the same peer crowd, and adolescents' social acceptance. METHODS: We interviewed 250 high school students and identified six categories: popular, jocks, brains, burnouts, nonconformists, or average/other. Adolescents also reported on their health-risk behaviors (including use of cigarettes, alcohol, marijuana and other drugs; risky sexual behaviors; and other risk-taking behaviors), the health-risk behaviors of their friends, the peer crowd affiliation of their closest friends, and their perceived social acceptance. RESULTS: Burnouts and nonconformists had the highest levels of health-risk behaviors across the areas assessed, the greatest proportions of close friends who engaged in similar behaviors, and relatively low social acceptance from peers. Brains and their friends engaged in extremely low levels of health-risk behaviors. Jocks and populars also showed evidence of selected areas of health risk; these teens also were more socially accepted than others. In general, adolescents' closest friends were highly nested within the same peer crowds. CONCLUSIONS: The findings further our understanding of adolescent behaviors that put them at risk for serious adult onset conditions associated with high rates of morbidity and mortality. We discuss the implications of the findings for developing health promotion efforts for adolescents.

Alcohol use and health behavior lifestyles among U.S. women: the behavioral risk factor surveys.

Alcohol use is a complex behavior, occurring in the context of an overall health lifestyle. We used data from a nationally representative telephone survey (N = 12,467 women) to examine associations between binge drinking, chronic drinking, and other health behaviors. Certain health-risk behaviors (e.g., smoking, drunk driving, and seatbelt nonuse) tend to cluster with alcohol misuse. These may act synergistically, thus augmenting the negative health effects of alcohol misuse. Conversely, some health behaviors (e.g., eating or exercising, particularly in response to stress) are negatively associated with alcohol misuse and may serve similar functions for some women. Finally, binge drinking occurs more frequently among women who may have relatively restrictive eating behaviors and higher levels of interpersonal stress. Our findings suggest that alcohol prevention and treatment programs should address sociodemographic and health lifestyle factors that initially predispose an individual to engage in health-risk behaviors and should recognize the interdependent patterns of behaviors associated with alcohol misuse. This approach will help prevent substitutions, recurrence, or induction of detrimental behaviors and will identify potentially negative interactions between existing concurrent health-risk behaviors.

Risk behavior in a community sample of children and adolescents.

OBJECTIVES: First, to investigate whether there is covariation between risk behaviors, including suicidality, in a community probability sample of children and adolescents; and second, to investigate whether risk behavior is associated with selected potential correlates. METHOD: A sample of 9- to 17-year-old youths (N = 1,285) and their caretakers were interviewed in the Methods for the Epidemiology of Child and Adolescent Mental Disorders (MECA) Study. The risk behaviors were marijuana smoking, alcohol use, intercourse, fighting, cigarette smoking, and suicidal ideation/attempts. Relationships between the risk behaviors were described using odds ratios. Linear regression analyses of an index of risk behavior on the selected potential correlates of risk behavior were conducted. RESULTS: There were significant relationships between all pairs of risk behaviors. The score on the index of risk behavior was associated with stressors, lack of resources, family psychiatric disorder, psychopathology, and functional impairment. CONCLUSIONS: Clinicians should be alerted to the possibility of risk behaviors, especially in children and adolescents engaging in other risk behaviors and those with inadequate resources, stressors, functional impairment, or psychopathology.

Effects of at-school victimization and sexual orientation on lesbian, gay, or bisexual youths' health risk behavior.

PURPOSE: To examine the link between victimization at school and health risk behaviors using representative data comparing lesbian, gay, and bisexual (LGB) youths and heterosexual youths. METHODS: Data from the 1995 Youth Risk Behavior Survey taken in Massachusetts and Vermont were examined. This sample included 9188 9th through 12th grade students; 315 of these students were identified as LGB. Analyses of variance were used to examine health risk behaviors by sexual orientation by gender by victimization level. RESULTS: The combined effect of LGB status and high levels of at-school victimization was associated with the highest levels of health risk behaviors. LGB youths reporting high levels of at-school victimization reported higher levels of substance use, suicidality, and sexual risk behaviors than heterosexual peers reporting high levels of at-school victimization. Also, LGB youths reporting low levels of at-school victimization reported levels of substance use, suicidality, and sexual-risk behaviors that were similar to heterosexual peers who reported low at-school victimization. CONCLUSIONS: The findings provide evidence that differences in health risks among LGB youth are mediated by victimization at school. Such victimization of LGB youth is associated with health risk behaviors.

An analysis of the process of human immunodeficiency virus sexual risk behavior change.

Few studies have tried to identify the process of risk behavior change. In this paper, we present a method for the analysis of the process of risk behavior change; the methodology involves using time series data to form transition probability matrices. We apply the method to human immunodeficiency virus (HIV) sexual risk behavioral data from a cohort of gay men in Amsterdam. We determine the process of risk behavior change in this cohort, and we demonstrate that it is not possible to deduce the process simply from an examination of the static pattern. Our results imply that the risk behavior change that is observed in this cohort may be viewed as a homogeneous one-step Markovian process. This process of risk behavior change has implications for the long-term prediction of HIV seroconversion rates and for the design and evaluation of HIV behavioral intervention studies and vaccine trials. Our results also have implications for the interpretation of relapse behavior.
