RÉSUMÉ

Children are a priority population for skin cancer prevention as excessive sun exposure in childhood increases the risk of melanoma in adulthood. The complexity of sun protective behaviors has posed measurement challenges for trials testing intervention efficacy. The current study evaluated a sun safety intervention for schoolchildren using latent transition analysis (LTA) to examine patterns of sun protection behaviors over time. A three-armed randomized controlled trial was conducted between 2012 and 2016 with two intervention groups (N = 3368) and an observation-only control group (N = 342) among 4th and 5th graders from 24 public schools in Los Angeles County. Both interventions conditions were grouped and compared to controls. Five self-reported sun protective behaviors were measured at baseline and three-month follow-up: use of sunscreen, long sleeves, long pants, hats, and shade seeking. Participants comprised 3710 schoolchildren, mean age 9 years, 47% female and 69% Latino. At baseline, four patterns of sun protection behaviors were found: children who engaged in 1) all sun protective behaviors; 2) few protective behaviors; 3) protective clothing and shade only; and 4) hats only. Children in the control group were likely to remain in their baseline status or transition to a less protective status at three-month follow-up. By contrast, 30% of children in the intervention group transitioned to a more protective status at follow-up. In this RCT of a sun safety intervention, children in the intervention transitioned to more protective behaviors compared to controls. Using LTA enriches understanding of intervention efficacy by modeling the complexity of sun protection behaviors over time.

RÉSUMÉ

BACKGROUND: Youth from continuation high schools report greater substance use and sensation-seeking than youth from regular high schools, yet their long-term consequences on age at sexual onset and the number of sexual partners are unknown. OBJECTIVE: To examine substance use, sensation-seeking and sexual behaviors by gender and race/ethnicity and the effects of substance use and sensation-seeking in adolescence on age at sexual initiation and numbers of sexual partners by young adulthood. METHODS: Baseline and 4-year follow-up data on youth from 14 continuation high schools in Southern California who participated in a drug abuse prevention intervention were analyzed. Structural equation modeling assessed whether or not substance use or sensation-seeking in adolescence predicted age at sexual onset and numbers of sexual partners by young adulthood. RESULTS: Latinos had lower sensation-seeking and frequency of substance use and a later age at sexual onset than non-Latinos. Males were more likely than females to have multiple lifetime and recent sexual partners. The effects of adolescent substance use on the number of sexual partners by young adulthood were mediated fully by their age at sexual initiation. Sensation-seeking had no direct or indirect effects on sexual behaviors. Conclusions/Importance: Factors leading to and actual sexual risk behaviors among youth from continuation high schools vary by race/ethnicity and gender. Targeting these antecedent factors by race/ethnicity and gender may improve prevention efforts.

RÉSUMÉ

Although rates of late-stage melanoma are rising in Hispanics, particularly those living in high ultraviolet light environments, little is known about the prevalence of sun protective behaviors in Hispanic children. We analyzed baseline data including frequency of sunburn, sun protective behaviors, level of U.S. acculturation, and skin phototype from a cross-sectional survey of 2003 Hispanic elementary school children in Los Angeles, California, who participated in a skin cancer prevention intervention. Although the Hispanic children reported frequently engaging in some sun protective behaviors, they also had a high rate of sunburn (59%) that exceeded previous national estimates for non-Hispanic white children (43%). Fewer U.S.-acculturated children reported more frequent shade-seeking at home (P = .02), along with less shade-seeking at school (P = .001) and more sunscreen use at school (P = .02). The surprisingly high rate of sunburn in Hispanic children suggests that the way in which they are practicing sun protection is not preventing sunburns. Sun safety interventions should be targeted toward Hispanic youth to provide them with practical methods of effective sun protection, in addition to education on the risks of high sun exposure.

RÉSUMÉ

BACKGROUND/PURPOSE: Rates of melanoma are rising in Hispanics in the United States. Excessive sun exposure in childhood increases the risk of melanoma in adulthood, and little is known about the factors motivating sun protection behaviors among Hispanic youth. METHODS: Correlates of sun protection were examined among Hispanic children residing in Los Angeles, California (N = 1891). Associations between multiple constructs (psychosocial, familial, and cultural) and sun protection outcomes (use of sunscreen, protective clothing, and shade seeking/sun avoidance) were examined. RESULTS: Family variables were associated with more frequent sun protection among Hispanic children across outcomes, as were perceived peer norms, perceived self-efficacy, and fewer sun protection barriers. Skin cancer risk factors such as lighter skin and sunburn experience, and level of acculturation were not associated with greater sun protection. CONCLUSION: Family sun protection habits are instrumental to Hispanic children's sun safe behaviors, and interventions that engage the family may be most effective. Increasing risk communication to high-risk subgroups of Hispanic children (those with lighter, more sun reactive skin) is important when developing intervention strategies. However, there is overlap between Hispanic children's sun protection correlates and those observed among non-Hispanic white children, suggesting that interventions to improve sun protection may generalize across cultural contexts.

RÉSUMÉ

BACKGROUND: Invasive melanoma is becoming more common in U.S. Hispanics, yet little is known about the sun protection behaviors in this population, particularly children and adolescents who incur high ultraviolet (UV) exposures. METHODS: We used latent class analysis to examine patterns of sun protective behaviors in a cross-sectional survey of Hispanic elementary students participating in a sun safety intervention in Los Angeles from 2013- to 2014 (N=972). Five behavior indicators in two environments (school and home) representing multiple methods of sun protection were selected for the model. RESULTS: Results suggested a four-class model best fit the data. Classes were labeled in order of increasing risk as multiple protective behaviors (28%), clothing and shade (32%), pants only (15%), and low/inconsistent protective behaviors (25%). Children who reported high parental engagement with sun protection were significantly more likely to be classified in high overall protective categories (odds ratio (OR)=4.77). Girls were more likely than boys to be classified in the highest protecting class (OR=3.46), but were also more likely to be in the "pants only" class (OR=2.65). Sensitivity to sunburn was associated with less likelihood of being in the "clothing and shade" class (OR=0.53). CONCLUSION: The differences among these classes and their predictors reveal the heterogeneity and complexity of Hispanic children's sun protective behaviors. These findings have implications for the design and delivery of future sun protection interventions targeting Hispanic children, as strategies tailored to specific subgroups may be more effective in achieving meaningful behavioral changes.

RÉSUMÉ

HIV-infected women with excessive alcohol consumption are at risk for adverse health outcomes, but little is known about their long-term drinking trajectories. This analysis included longitudinal data, obtained from 1996 to 2006, from 2,791 women with HIV from the Women's Interagency HIV Study. Among these women, the proportion in each of five distinct drinking trajectories was: continued heavy drinking (3 %), reduction from heavy to non-heavy drinking (4 %), increase from non-heavy to heavy drinking (8 %), continued non-heavy drinking (36 %), and continued non-drinking (49 %). Depressive symptoms, other substance use (crack/cocaine, marijuana, and tobacco), co-infection with hepatitis C virus (HCV), and heavy drinking prior to enrollment were associated with trajectories involving future heavy drinking. In conclusion, many women with HIV change their drinking patterns over time. Clinicians and those providing alcohol-related interventions might target those with depression, current use of tobacco or illicit drugs, HCV infection, or a previous history of drinking problems.

RÉSUMÉ

Injection drug users (IDUs) are at risk for HIV and other bloodborne pathogens through receptive syringe sharing (RSS) and receptive paraphernalia sharing (RPS). Research into the influence of the perceived risk of HIV infection on injection risk behavior has yielded mixed findings. One explanation may be that consequences other than HIV infection are considered when IDUs are faced with decisions about whether or not to share equipment. We investigated the perceived consequences of refusing to share injection equipment among 187 IDUs recruited from a large syringe exchange program in Los Angeles, California, assessed their influence on RSS and RPS, and evaluated gender differences. Two sub-scales of perceived consequences were identified: structural/external consequences and social/internal consequences. In multiple linear regression, the perceived social/internal consequences of refusing to share were associated with both RSS and RPS, after controlling for other psychosocial constructs and demographic variables. Few statistically significant gender differences emerged. Assessing the consequences of refusing to share injection equipment may help explain persistent injection risk behavior, and may provide promising targets for comprehensive intervention efforts designed to address both individual and structural risk factors.

RÉSUMÉ

Injection drug users (IDUs) are at a risk for HIV and other bloodborne pathogens via syringe and paraphernalia sharing, with females being at elevated risk. Consequences of injection risk behavior such as the risk of becoming infected with HIV have been relatively well studied, though less is known about the consequences of refusing to share injection equipment. We conducted indepth qualitative interviews with 26 IDUs recruited from a syringe exchange program in Los Angeles, California, USA, to understand the consequences of refusing to share injection equipment and to determine whether these perceived consequences differ by gender. Perceived consequences were organized into four domains using a social ecological framework: microsystem (perceived risk for HIV, drug withdrawal or forgoing drug use), exosystem (trust and social norms), mesosystem (precarious housing and shelter policies), and macrosystem (syringe access/inconvenience, economic and legal consequences). Gender differences were identified in some, but not in all areas. Effective public health interventions among IDUs will benefit from a holistic perspective that considers the environmental and social rationality (Kowalewski, M., Henson, K.D., & Longshore, D. (1997). Rethinking perceived risk and health behavior: A critical review of HIV prevention research. Health Education and Behavior, 24(3), 313-325) of decisions regarding injection risk behavior and assists individuals in addressing the consequences that they perceive to be the most salient.

RÉSUMÉ

We evaluated pain frequency and severity in 339 women enrolled in the Women's Interagency HIV Study (WIHS). Among these, 63% were 39 years of age or younger, 17% were white, 54% African American, and 29% Hispanic; 32% did not complete high school; 58% had a CD4 less than 200; 65% had clinical AIDS; 60% were on highly active antiretroviral therapy (HAART); and 32% had a viral load of 50,000 or more. Data were collected between 1996 and 1998. Within the past 6 months 190 (56%) women experienced pain 6 or more days and 168 (50%) women indicated pain severity scores of 4 or 5 (5-point scale). Pain frequency and pain severity were not associated with age, education, ethnicity, current therapy, or location of the WIHS site. Pain frequency and severity were related to lower CD4 count, higher depression, with a history and longer duration of smoking and use of marijuana. Severity was associated with a history of crack/cocaine or heroin use or with injection drug use as the transmission category. In the multivariate models, pain severity was related to CD4 count and depression and to current tobacco use but not to crack, cocaine, heroin, or marijuana use. Pain frequency was related to depression and to former tobacco, crack, cocaine, heroin, or marijuana use but not to current use. The long-term effects of tobacco use may be to increase pain experience but women may also smoke tobacco or use other substances to give mild pain relief. Pain is frequent and often severe among women with HIV requiring medical management.

RÉSUMÉ

Hazardous alcohol consumption among women with human immunodeficiency virus (HIV) infection is associated with several adverse health and behavioral outcomes, but the proportion of HIV-positive women who engage in hazardous drinking over time is unclear. The authors sought to determine rates of hazardous alcohol consumption among these women over time and to identify factors associated with this behavior. Subjects were 2,770 HIV-positive women recruited from 6 US cities who participated in semiannual follow-up visits in the Women's Interagency HIV Study from 1995 to 2006. Hazardous alcohol consumption was defined as exceeding daily (> or =4 drinks) or weekly (>7 drinks) consumption recommendations. Over the 11-year follow-up period, 14%-24% of the women reported past-year hazardous drinking, with a slight decrease in hazardous drinking over time. Women were significantly more likely to report hazardous drinking if they were unemployed, were not high school graduates, had been enrolled in the original cohort (1994-1995), had a CD4 cell count of 200-500 cells/mL, were hepatitis C-seropositive, or had symptoms of depression. Approximately 1 in 5 of the women met criteria for hazardous drinking. Interventions to identify and address hazardous drinking among HIV-positive women are urgently needed.

RÉSUMÉ

Documenting fidelity to HIV prevention interventions is critical to ensure consistency in intervention implementation and necessary for measuring intervention exposure and, ultimately, outcomes. Significant variation from prescribed protocols or inconsistent implementation can jeopardize the integrity of evaluation research and render outcomes uninterpretable. There is increasing support for HIV prevention models targeting seropositive individuals designed to be delivered by physicians during clinic visits. Assessing fidelity to physician-delivered interventions that occur during clinical exams present unique challenges. This paper presents findings from various data sources designed to track intervention fidelity and exposure to the Partnership for Health intervention, a physician-delivered HIV prevention intervention implemented in an urban community HIV clinic. We present findings from chart abstraction data, patient surveys and exit interviews, and provider qualitative interviews. Lessons learned and recommendations for maximizing the accuracy and validity of fidelity assessment in future evaluations of HIV prevention interventions in primary care settings are considered.

RÉSUMÉ

People living with HIV/AIDS (PLWHA) who experience homelessness have competing priorities (e.g., food, security of property) and experience complex health-related issues (e.g., co-morbidities, transportation to clinics) that may interfere with utilizing health care services. Using data from 229 PLWHA we did not find that homelessness was related to fewer or shorter clinic visits. Patients who had ever been homeless were more likely to have a case manager (74.2%) than never homeless patients (58.8%). African American patients were less likely to have a case manager (57%) as compared to other ethnicities (66%) although this was not statistically significant.

RÉSUMÉ

The correlates of unprotected sex among a sample of heterosexual men living with HIV (n = 121) were examined to determine whether patient characteristics can be used as a basis for tailoring safer sex counseling in the clinic setting. Potential correlates of self-reported unprotected oral sex (fellatio) and vaginal sex included participant demographics (e.g., age, ethnicity), disease status (CD4 counts, viral load, years since diagnosis), safer sex beliefs (e.g., condom attitudes), substance use, psychological characteristics (depressive symptoms, dispositional optimism and pessimism), and sex partner characteristics (main/casual partner, HIV status of partner, and duration of relationship). A series of logistic regression analyses were used to determine significant relationships. Correlates of reported levels of prior 3-month unprotected fellatio (24%) and vaginal (21%) sex were not associated with the type of relationship (main or casual) or perceived HIV serostatus of the partner (positive, negative, or unknown). Unprotected fellatio was positively associated with age and CD4 count and inversely associated with optimism and positive condom attitudes (all p's < 0.05). Unprotected vaginal sex was positively associated with duration of relationship and inversely associated with positive condom attitudes. Prevention efforts among sexually active adult heterosexual men living with HIV may benefit from focusing on improving attitudes towards condom use regardless of partner relationship status.

RÉSUMÉ

OBJECTIVES: We used longitudinal data to examine the roles of 4 dimensions of patient satisfaction as both predictors and outcomes of use of highly active antiretroviral therapy (HAART) among women in the United States with HIV/AIDS. METHODS: Generalized estimating equations were used to analyze time-lagged satisfaction-HAART relationships over 8 years in the Women's Interagency HIV Study. RESULTS: Multivariate models showed that, over time, HAART use was associated with higher patient satisfaction with care in general, with providers, and with access/convenience of care; however, patient satisfaction was not associated with subsequent HAART use. Symptoms of depression and poor health-related quality of life were associated with less satisfaction with care on all 4 dimensions assessed, whereas African American race/ethnicity, illegal drug use, and fewer primary care visits were associated with less HAART use. CONCLUSIONS: Our findings suggest that dissatisfaction with care is not a reason for underuse of HAART among women with HIV and that providers should not be discouraged from recommending HAART to dissatisfied patients. Rather, increasing women's access to primary care could result in both increased HAART use and greater patient satisfaction.

RÉSUMÉ

BACKGROUND: The evidence that drug treatment programs are associated with changes in sexual behavior and, thus, have prevention benefits beyond addiction is inconclusive. We examined whether entry into drug treatment was associated with subsequent alterations in sexual behavior among a group of drug-using women. METHODS: Data were collected semiannually via structured interviews over 8 years. Generalized estimating equations evaluated the relationship between self-reported drug treatment at each visit and sexual abstinence and consistent condom use in the subsequent 6-month period. RESULTS: In this sample (N = 1,658; mean age, 37.3 years; 57.5% African American; 80.3% HIV positive; 49.6% crack/cocaine users), 40% reported being in a variety of drug treatment programs. Those undergoing drug treatment (vs. those not) were less likely to become sexually active (adjusted odds ratio [AOR], 0.83; 95% confidence interval [CI], 0.76-0.91); this association was unchanged when the frequency of attendance and number of different drug treatment programs were evaluated. Drug treatment was not associated with subsequent consistent condom, regardless of frequency of attendance, but involvement in at least three treatment programs was (AOR, 1.40; 95% CI, 1.00-1.97). CONCLUSIONS: Additional efforts are needed to integrate effective sexual risk reduction programs into drug treatment settings; expanding access to different types of drug treatment modalities may be indicated.

RÉSUMÉ

Antiretroviral therapy (ART) is effective in controlling viral load in many people infected with HIV, but high levels of adherence to ART are needed for prolonged viral suppression. This study evaluated a brief adherence intervention delivered to HIV-positive patients by primary care providers during routine medical examinations. Six clinics were randomly allocated to deliver an intervention focusing on ART adherence (2 clinics) or safer sex (4 clinics). Interventions included written information (posters, brochures, and flyers) and brief counseling from providers and were evaluated with cohorts of randomly selected patients (n = 437) measured before and after a 10-month intervention. Among those 95% or greater adherent at baseline, 91% of patients who received the adherence intervention remained 95% or greater adherent at follow-up compared with 75% of the patients who received the safer sex intervention (chi = 12.59, P < 0.01). This difference was significant in a logistic regression analysis (odds ratio = 2.26; 95% confidence interval = 1.27-4.04), adjusting for baseline adherence, demographics, and HIV medical status. The adherence intervention did not significantly increase the prevalence of 95% or greater adherence among patients less than 95% adherent at baseline. Similar but nonsignificant results were observed for viral load. A brief intervention delivered to HIV patients by their primary providers helped to maintain adequate adherence to ART regimens. More intensive intervention is needed to improve adherence among patients who are initially less than 95% adherent.

RÉSUMÉ

OBJECTIVE: To evaluate the neurocognitive function in 220 women enrolled in the Women's Interagency HIV Study (WIHS), a study of disease progression in women living with HIV/AIDS and in HIV-negative controls. METHODS: We evaluated the prevalence of abnormal neuropsychological (NP) results in hepatitis C virus (HCV)-positive compared with HCV-negative women in combination with HIV serostatus. RESULTS: NP impairment was significantly higher for HCV-positive women in comparison with HCV-negative women [odds ratio (OR), 2.03; 95% confidence interval (CI), 1.17-3.51]. Women co-infected with HCV and HIV demonstrated greater abnormal NP performance than those not infected with either, particularly if there was evidence of CD4 T-lymphocyte immunosuppression [> 200 x 10(6) CD4 cells/l (OR, 3.48; 95% CI, 1.49-8.15) and < or = 200 x 10(6) CD4 cells/l (OR, 5.38; 95% CI, 1.46-19.84)]. Women who were HCV-positive/HIV-positive and not taking antiretroviral therapy (ART) were more likely (OR, 7.03; 95% CI, 2.63-18.82) to demonstrate NP impairment than those who were HCV-negative/HIV-negative. In analyses controlling separately for education, intelligence quotient, depression, sedating drug use, head injury, ethnicity, and history of substance use, HCV continued to significantly predict NP impairment. The HCV effect did not reach significance when controlling for age in bivariate or multivariate analyses although the odds ratio for NP abnormalities in HCV-infected patients was only slightly reduced (ORs above 1.9). After testing for an interaction between age and infection status, we conducted age-stratified analysis and showed a significant effect of infection status for those aged under 40 years. CONCLUSIONS: The effect of aging on co-infected populations will require further study. This study has demonstrated the association of HCV with the risk of neurocognitive impairment in women living with HIV/AIDS and suggests that co-infection has an additive effect.

RÉSUMÉ

Previous research suggested that the availability of highly active antiretroviral therapy (ART) was associated with increased risky sexual behavior. This study examined the relationship between unprotected anal or vaginal sex (UAV) and ART use and adherence in a cross-sectional survey conducted in 874 randomly selected, sexually active patients at 6 public HIV clinics in California. Patients completed a standardized interview in 1998-1999 regarding HIV history, sexual behavior, illicit drug use, and ART use and adherence. Thirty-four percent reported UAV, defined as anal or vaginal sex without a condom within the past 3 months. Of 79% on ART, 26% reported <95% adherence. Decreased odds for UAV were found for both ART use, odds ratio (OR) 0.5 (95% CI 0.4-0.7, P < 0.001) and adherence to ART of > or = 95%, OR 0.6 (95% CI 0.4-0.8, P < 0.001). These relationships persisted in most stratified analysis for both ART use and adherence but in multivariate analysis only for ART use. An undetectable HIV RNA was associated with decreased odds of UAV, OR 0.6 (95% CI 0.5-0.8, P < 0.001). Contrary to expectations, use of and adherence to ART and their consequent suppression of HIV were associated with a decreased prevalence of self-reported risky sexual behavior.

RÉSUMÉ

OBJECTIVE: Successful behavioral interventions to promote safe sex must be tailored to the sexual behaviors and relationships of individual patients. The aim of this study is to examine the distribution of unprotected anal and vaginal sex (UAV) and nondisclosure (ND) among categories of HIV-positive men and women based on relationship factors. These factors can be easily assessed and used as a basis for tailoring safer sex counseling in the clinic setting. METHODS: Eight hundred forty HIV-positive persons who were sexually active and attending 1 of 6 clinics in California were surveyed. Participants were categorized on the basis of numbers of partners, sexual orientation, type of relationship, and partner serostatus. Self-reported UAV, ND, and duration of the relationship were reported for each category and were examined. RESULTS: UAV was lower for those with 1 partner (26%) as compared with those with 2 or more partners (50%). ND was also lower for those with 1 partner (20%) as compared with those with 2 or more partners (60%). For those with 1 main partner, we found no significant differences in UAV by sexual orientation. UAV with seronegative main partners ranged from 16% to 20%, whereas UAV with seropositive partners ranged from 37% to 46%. Among men who have sex with men with 2 or more partners, relationships were more likely to be casual, of short duration, and to have higher levels of UAV and ND. CONCLUSION: The number of sex partners, type of relationship, and perceived HIV serostatus of a partner influence sexual behaviors and may be an efficient and effective basis for tailoring prevention messages.
