Medication beliefs as mediators of the health literacy-antiretroviral adherence relationship in HIV-infected individuals.

Identifying modifiable barriers to antiretroviral adherence remains an important aim. We hypothesized that mistaken beliefs regarding taking HIV medications mediated the relation between low literacy and poor adherence. We studied 87 HIV-infected individuals on standard antiretroviral regimens for >or= 3 months. Adherence was assessed using pharmacy refill records. Medication beliefs, including an individual's norm for acceptable adherence, were measured using questions developed by expert panel. Literacy was associated with >or=95% adherence (64% for >or=9th grade level vs. 40% for <9th grade level). Participants with <95% adherence had a lower threshold of acceptable adherence than those with >or=95% adherence [80% adherence (interquartile range 70-90%) vs. 90% adherence (interquartile range 80-90%)]. However, the effect was independent of literacy. No other beliefs assessed were associated with adherence. Although the beliefs assessed do not mediate the relation between literacy and adherence, we identified low adherence norms as a potentially modifiable belief associated with adherence.

Menstrual irregularity from hormonal contraception: a cause of reproductive health concerns in minority adolescent young women.

CONTEXT: Adolescents are frequent users of hormonal contraception (HC), yet their adherence to these methods is often poor. Concerns about side effects, especially those affecting the menstrual system, are often given as reasons for contraceptive nonadherence or discontinuation. We sought to identify teens' concerns and misperceptions about the menstrual-related side effects of HC. METHODS: Open focus groups were conducted with both sexually active and virgin adolescent women aged 12-18 years who were recruited from the Philadelphia area. The adolescents did not have to be contraceptive users in order to participate. The question put to each group was, "What are the things you have heard about the birth control pill, Depo-Provera and Norplant?" Groups were audio-recorded, transcribed and analyzed using qualitative software. RESULTS: We conducted 13 female-only groups. Participants raised frequent concerns about menstrual-related side effects, believing that these side effects were evidence of possible negative effects of HC on their reproductive health. Four themes related to hormonal contraceptive-induced menstrual irregularity emerged from the groups. Theme 1: Menstruation is natural and should not be altered in any way. Theme 2: The menstrual period is necessary for cleansing of the body. Theme 3: "Spotting," intermenstrual bleeding and amenorrhea cause doubts about the method's effectiveness and worries about pregnancy. Theme 4: All menstrual irregularity, from intermenstrual bleeding to amenorrhea, causes worry about the effects on fertility and on physical health. CONCLUSIONS: Teens have concerns about the menstrual irregularity caused by HC. Providers understand that these side effects are minor and of little medical consequence. Yet, adolescent patients may be ascribing great significance to these effects and may be declining these methods because of fear and misperceptions.

Changes in religiousness and spirituality attributed to HIV/AIDS: are there sex and race differences?

BACKGROUND/OBJECTIVE: Having a serious illness such as HIV/AIDS raises existential issues, which are potentially manifested as changes in religiousness and spirituality. The objective of this study was (1) to describe changes in religiousness and spirituality of people with HIV/AIDS, and (2) to determine if these changes differed by sex and race. METHODS: Three-hundred and forty-seven adults with HIV/AIDS from 4 sites were asked demographic, clinical, and religious/spiritual questions. Six religious/spiritual questions assessed personal and social domains of religiousness and spirituality. RESULTS: Eighty-eight participants (25%) reported being "more religious" and 142 (41%) reported being "more spiritual" since being diagnosed with HIV/AIDS. Approximately 1 in 4 participants also reported that they felt more alienated by a religious group since their HIV/AIDS diagnosis and approximately 1 in 10 reported changing their place of religious worship because of HIV/AIDS. A total of 174 participants (50%) believed that their religiousness/spirituality helped them live longer. Fewer Caucasians than African Americans reported becoming more spiritual since their HIV/AIDS diagnosis (37% vs 52%, respectively; P<.015), more Caucasians than African Americans felt alienated from religious communities (44% vs 21%, respectively; P<.001), and fewer Caucasians than African Americans believed that their religiousness/spirituality helped them live longer (41% vs 68% respectively; P<.001). There were no significantly different reported changes in religious and spiritual experiences by sex. CONCLUSIONS: Many participants report having become more spiritual or religious since contracting HIV/AIDS, though many have felt alienated by a religious group-some to the point of changing their place of worship. Clinicians conducting spiritual assessments should be aware that changes in religious and spiritual experiences attributed to HIV/AIDS might differ between Caucasian and African Americans.

Brief communication: physical abuse of boys and possible associations with poor adult outcomes.

BACKGROUND: Men's childhood physical abuse experiences are understudied. OBJECTIVE: To obtain descriptions about men's personal childhood physical abuse histories and estimate their association with adult outcomes. DESIGN: Population-based telephone survey. SETTING: Urban areas with high frequency of domestic violence against girls and women. PARTICIPANTS: 298 men recruited through random-digit dialing. MEASUREMENTS: 6 Conflict Tactics Scale items and psychiatric, sexual, and legal history questions. RESULTS: One hundred of 197 (51%) participants had a history of childhood physical abuse. Most (73%) participants were abused by a parent. Childhood physical abuse history was associated with depression symptoms (P = 0.003), post-traumatic stress disorder symptoms (P < 0.001), number of lifetime sexual partners (P = 0.035), legal troubles (P = 0.002), and incarceration (P = 0.007) in unadjusted analyses and with depression symptoms (P = 0.015) and post-traumatic stress disorder symptoms (P = 0.003) in adjusted analyses. LIMITATIONS: There may have been inaccurate recall of past events. Lack of exposure time data disallowed direct comparison of abuse perpetration by mothers versus fathers. Other unmeasured variables related to childhood physical abuse might better explain poor adult outcomes. CONCLUSIONS: The high frequency of childhood physical abuse histories in this population-based male sample, coupled with the high proportion of parent perpetrators and the association between childhood physical abuse and adult outcomes that are often associated with perpetration of violence, argues for more study of and clinical attentiveness to potential adult outcomes of men's own childhood physical abuse histories.

Men's pathways to risky sexual behavior: role of co-occurring childhood sexual abuse, posttraumatic stress disorder, and depression histories.

Recent reports of sexually transmitted infection-rate increases among men indicate the need for renewed study of male sexual risk behavior to aid development of updated and novel risk reduction interventions. Men who have childhood sexual abuse (CSA) histories consistently report frequent sexual risk behavior. The objective of this sturdy is to explore whether posttraumatic stress disorder (PTSD) and depression are moderators and/or mediators of the association between CSA and sexual risk in adult men. A cross-sectional survey study employing random digit dial recruitment was administered to men aged 18-49 years from Philadelphia County. Two hundred ninety eight men were recruited and screened for CSA history, administered items from the Posttraumatic Stress Diagnostic Scale (PDS) and Center for Epidemiologic Studies- Depression (CES-D), and asked to estimate their number of lifetime sexual partners (LSPs). Effects of sociodemographic characteristics, CSA, PTSD, and depression on the number of LSPs were modeled using Poisson regression. Results show that 197 (66%) men participated; 43 (22%) had CSA histories. CSA was significantly associated with PTSD/depression (P=.03). Four sociodemographic variables (age, race, sexual identity, and education), CSA (incidence rate ratio, IRR=1.47, P<.001), PTSD (IRR=1.19, P=.04), depression (IRR=1.29, P=.001), all 2-way interactions, and the 3-way CSA/PTSD/depression interaction (IRR=11.00, P<.001) were associated with the number of LSPs (R2=0.27). In conclusion, sexual partnership patterns unique to men with CSA histories and comorbid PTSD/depression appear to lead to substantially higher numbers of LSPs. Estimates of this relationship may have been biased toward the null by underreporting that can occur with phone surveys. Cross-sectional studies do not support causal inferences; however, the identification of a moderating and mediating influence of PTSD/depression on the relationship between CSA and sexual risk behavior is important and suggests the need for future studies with larger samples that examine trajectories for CSA, psychiatric illness, and sexual partnerships.

Developing a patient intervention to reduce antibiotic overuse.

The emergence of drug resistance among common community-acquired bacterial infections has been clearly linked to the overuse of antibiotics. To address this problem, guidelines have been developed for the judicious use of antibiotics, particularly with regard to respiratory infection in adults and children. In addition, the CDC has promulgated guidelines for the general public, exhorting patients not to take an antibiotic for viral illnesses, not to pressure practitioners for antibiotic therapy, not to use antibiotics prescribed for another person, and not to use antibiotics left over from a previous illness. Despite some overall decline in antibiotic use, patients continue to engage in antibiotic overuse practices, resulting in increasing antimicrobial resistance. One reasons for antibiotic overuse is "antibiotic expectation," in which patients expect to be treated with an antibiotic for an acute infection, whether it is viral or bacterial.1 This phenomenon points to an underlying system of beliefs held by patients toward antibiotic use that may be alterable by educational interventions.

HIV-seropositive individuals' optimistic beliefs about prognosis and relation to medication and safe sex adherence.

OBJECTIVE: The study objective was to characterize respondents' prognostic perceptions of HIV infection and to explore how perceptions might affect medication and safe sex nonadherence. METHODS: Surveys were mailed to 295 clients of an HIV-specific case management organization. Participants were asked to describe experience with HIV/AIDS right after serostatus knowledge and currently, using provided word lists, after which they were asked to assess current life expectancy. Self-reported information on antiretroviral medication and safe sex nonadherence was obtained. RESULTS: A total of 220 (75%) clients (66% nonwhite, 73% male, 63% gay/bisexual, 50% educated >12 years, and 53% with incomes <$10,000/year) returned surveys. Negative descriptors from word lists were significantly less common and positive descriptors significantly more common now compared to right after serostatus knowledge. Current perceptions about life expectancy indicated that most respondents thought they would live many years, many believing they would live well into old age. Whites (odds ratio [OR], 0.34; P =.01) were less likely and those with >12 years education (OR, 2.76; P =.02) and with CD4 cell counts >200 (OR, 2.70; P =.01) were more likely to have optimistic prognostic beliefs. The optimistic subgroup, when compared with the pessimistic subgroup, was more likely to report medication (26% vs 13%, P =.04) and safe sex (57% vs 29%, P =.004) nonadherence. CONCLUSIONS: Seropositive individuals, including persons of color (adjusted) as well as women and drug users (unadjusted), self-reported optimistic beliefs about their prognosis. Those with more optimism about their prognosis were significantly more likely to report medication and safe sex nonadherence. A better understanding of seropositive patients' prognostic beliefs and the factors determining them is warranted.
