Taking Be proud! Be responsible! to the Suburbs: A Replication Study
CONTEXT: An important phase of HIV prevention research is replicating successful interventions with different groups and in different settings.
METHODS: Be Proud! Be Responsible!, a successful intervention originally targeting black urban males and carried out in nonschool settings, was presented in health classes at urban and suburban schools with diverse student bodies. A group-randomized intervention study, which included 1,357 ninth and 10th graders from 10 paired schools in a Midwestern metropolitan area, was conducted in 2000-2002. Half the schools received the intervention, and half received a general health promotion program. Students\u27 reports of their sexual behavior and selected cognitive mediators were analyzed immediately following the programs and four and 12 months later.
RESULTS: Compared with students who received the control curriculum, students exposed to the intervention reported significantly greater knowledge of HIV, other STDs and condoms; greater confidence in their ability to control sexual impulses, to use condoms and to negotiate the use of condoms; and stronger intentions to use condoms. Stratified analyses revealed that the strongest intervention impacts were on knowledge and efficacy among males and students attending suburban schools. The intervention had no impact on sexual initiation, frequency of intercourse or condom use.
CONCLUSIONS: Schools are a logical and viable setting for the dissemination and acquisition of information about HIV, including prevention strategies. However, the behavioral impact of an intervention may not be easily transferable when the program is taught outside a carefully controlled, nonschool setting
Behavioral and cognitive interventions to improve treatment adherence and access to HIV care among older adults in sub-Saharan Africa: an updated systematic review
BACKGROUND: Approximately 14% of Africans infected with HIV are over the age of 50, yet few intervention studies
focus on improving access to care, retention in care, and adherence to antiretroviral therapy (ART) in this
population. A review of the published literature until 2012, found no relevant ART management and care interventions
for older people living with HIV (OPLHIV) in sub-Saharan Africa. The aim of this systematic review is to update the
original systematic review of intervention studies on OPLHIV, with a focus on evidence from sub-Saharan Africa.
METHODS: We conducted a systematic review of the available published literature from 2012 to 2017 to explore
behavioral and cognitive interventions addressing access to ART, retention in HIV care and adherence to ART in
sub-Saharan Africa that include older adults (50+). We searched three databases (MEDLINE, EMBASE, and Education
Resources Information Center) using relevant Medical Subject Headings (MeSH) terms as well as a manual search of the
reference lists. No language restrictions were placed. We identified eight articles which were analyzed using content
analysis with additional information obtained directly from the corresponding authors.
RESULTS AND DISCUSSION: There were no studies that exclusively focused on OPLHIV. Three studies referred only to
participants being over 18 years and did not specify age categories. Therefore, it is unclear whether these studies
actively considered people living with HIV over the age of 50. Although the studies sampled older adults, they lacked
sufficient data to draw conclusions about the relevance of the outcomes of this group.
CONCLUSIONS: These findings underscore the need to increase the evidence-base of which interventions will work for
older Africans on ART
The Role of Medical Language in Changing Public Perceptions of Illness
This study was designed to investigate the impact of medical terminology on perceptions of disease. Specifically, we look at the changing public perceptions of newly medicalized disorders with accompanying newly medicalized terms (e.g. impotence has become erectile dysfunction disorder). Does using “medicalese” to label a recently medicalized disorder lead to a change in the perception of that condition? Undergraduate students (n = 52) rated either the medical or lay label for recently medicalized disorders (such as erectile dysfunction disorder vs. impotence) and established medical conditions (such as a myocardial infarction vs. heart attack) for their perceived seriousness, disease representativeness and prevalence. Students considered the medical label of the recently medicalized disease to be more serious (mean = 4.95 (SE = .27) vs. mean = 3.77 (SE = .24) on a ten point scale), more representative of a disease (mean = 2.47 (SE = .09) vs. mean = 1.83 (SE = .09) on a four point scale), and have lower prevalence (mean = 68 (SE = 12.6) vs. mean = 122 (SE = 18.1) out of 1,000) than the same disease described using common language. A similar pattern was not seen in the established medical conditions, even when controlled for severity. This study demonstrates that the use of medical language in communication can induce bias in perception; a simple switch in terminology results in a disease being perceived as more serious, more likely to be a disease, and more likely to be a rare condition. These findings regarding the conceptualization of disease have implications for many areas, including medical communication with the public, advertising, and public policy
Women and postfertilization effects of birth control: consistency of beliefs, intentions and reported use
BACKGROUND: This study assesses the consistency of responses among women regarding their beliefs about the mechanisms of actions of birth control methods, beliefs about when human life begins, the intention to use or not use birth control methods that they believe may act after fertilization or implantation, and their reported use of specific methods. METHODS: A questionnaire was administered in family practice and obstetrics and gynecology clinics in Salt Lake City, Utah, and Tulsa, Oklahoma. Participants included women ages 18–50 presenting for any reason and women under age 18 presenting for family planning or pregnancy care. Analyses were based on key questions addressing beliefs about whether specific birth control methods may act after fertilization, beliefs about when human life begins, intention to use a method that may act after fertilization, and reported use of specific methods. The questionnaire contained no information about the mechanism of action of any method of birth control. Responses were considered inconsistent if actual use contradicted intentions, if one intention contradicted another, or if intentions contradicted beliefs. RESULTS: Of all respondents, 38% gave consistent responses about intention to not use or to stop use of any birth control method that acted after fertilization, while 4% gave inconsistent responses. The corresponding percentages for birth control methods that work after implantation were 64% consistent and 2% inconsistent. Of all respondents, 34% reported they believed that life begins at fertilization and would not use any birth control method that acts after fertilization (a consistent response), while 3% reported they believed that life begins at fertilization but would use a birth control method that acts after fertilization (inconsistent). For specific methods of birth control, less than 1% of women gave inconsistent responses. A majority of women (68% or greater) responded accurately about the mechanism of action of condoms, abstinence, sterilization, and abortion, but a substantial percentage of women (between 19% and 57%) were uncertain about the mechanisms of action of oral contraceptives, intrauterine devices (IUDs), Depo-Provera, or natural family planning. CONCLUSION: Women who believe that life begins at fertilization may not intend to use a birth control method that could have postfertilization effects. More research is needed to understand the relative importance of postfertilization effects for women in other populations, and in relation to other properties of and priorities for birth control methods. However, many women were uncertain about the mechanisms of action of specific methods. To respect the principles of informed consent, some women may need more education about what is known and not known about the mechanisms of action of birth control methods
Allocating HIV Prevention Funds in the United States: Recommendations from an Optimization Model
The Centers for Disease Control and Prevention (CDC) had an annual budget of approximately $327 million to fund health departments and community-based organizations for core HIV testing and prevention programs domestically between 2001 and 2006. Annual HIV incidence has been relatively stable since the year 2000 [1] and was estimated at 48,600 cases in 2006 and 48,100 in 2009 [2]. Using estimates on HIV incidence, prevalence, prevention program costs and benefits, and current spending, we created an HIV resource allocation model that can generate a mathematically optimal allocation of the Division of HIV/AIDS Prevention’s extramural budget for HIV testing, and counseling and education programs. The model’s data inputs and methods were reviewed by subject matter experts internal and external to the CDC via an extensive validation process. The model projects the HIV epidemic for the United States under different allocation strategies under a fixed budget. Our objective is to support national HIV prevention planning efforts and inform the decision-making process for HIV resource allocation. Model results can be summarized into three main recommendations. First, more funds should be allocated to testing and these should further target men who have sex with men and injecting drug users. Second, counseling and education interventions ought to provide a greater focus on HIV positive persons who are aware of their status. And lastly, interventions should target those at high risk for transmitting or acquiring HIV, rather than lower-risk members of the general population. The main conclusions of the HIV resource allocation model have played a role in the introduction of new programs and provide valuable guidance to target resources and improve the impact of HIV prevention efforts in the United States
Prevalence and socio-demographic correlates of physical activity levels among South African adults in Cape Town and Mount Frere communities in 2008-2009
BACKGROUND: Physical activity has been linked to reduced risk of various cardiometabolic disease, cancer, and
premature mortality. We investigated the prevalence and socio-demographic correlates of physical activity
among adults in urban and rural communities in South Africa. METHODS: This was a cross-sectional survey
comprising 1733 adults aged ?35 years from the Cape Town (urban) and Mount Frere (rural) sites of the
Prospective Urban Rural Epidemiology study. Physical activity was assessed using the validated International
Physical Activity Questionnaire. Multinomial logistic regressions were used to relate physical activity with
socio-demographic characteristics.
RESULTS: Overall, 74% of participants engaged in moderate-to-vigorous physical activity. In the adjusted regression
models, women were 34% less likely to engage in vigorous physical activity (OR =0.66, 95%-CI = 0.47-0.93). Physical
activity decreased with age, varied with marital status, education and occupation, always in differential ways
between urban and rural participants (all interactions p ? 0.047). For instance, in urban settings, those with
secondary education were more likely to engage in moderate physical activity (OR = 2.06, 95%-CI = 1.08-3.92)
than those with tertiary education. Single people were more likely to engage in high physical activity (OR = 2.10,
95%-CI = 1.03-4.28) than divorced. Overall, skilled participants were more likely to engage in vigorous physical
activity (OR = 2.07, 95%-CI = 1.41-3.05) driven by significant effect in rural area (OR = 2.70, 95%-CI = 1.51-4.83).
Urban participants were more likely to engage in moderate physical activity (OR = 1.67, 95%-CI = 1.31-2.13)
than rural participants.
CONCLUSIONS: To prevent chronic diseases among South Africans, attention should be paid to specific policies
and interventions aimed at promoting PA among young adults in rural and urban setting, and across the
social-economic diversity
Choice-Disability and HIV Infection: A Cross Sectional Study of HIV Status in Botswana, Namibia and Swaziland
Interpersonal power gradients may prevent people implementing HIV prevention decisions. Among 7,464 youth aged 15–29 years in Botswana, Namibia and Swaziland we documented indicators of choice-disability (low education, educational disparity with partner, experience of sexual violence, experience of intimate partner violence (IPV), poverty, partner income disparity, willingness to have sex without a condom despite believing partner at risk of HIV), and risk behaviours like inconsistent use of condoms and multiple partners. In Botswana, Namibia and Swaziland, 22.9, 9.1, and 26.1% women, and 8.3, 2.8, and 9.3% men, were HIV positive. Among both women and men, experience of IPV, IPV interacted with age, and partner income disparity interacted with age were associated with HIV positivity in multivariate analysis. Additional factors were low education (for women) and poverty (for men). Choice disability may be an important driver of the AIDS epidemic. New strategies are needed that favour the choice-disabled
Action-specific Cognitions of Planned and Preparatory Behaviors of Condom Use among Dutch Adolescents
Many adolescents fail to use condoms, even when they are motivated to do so. An important reason for their failure to use condoms is that they do not prepare themselves for potential sexual encounters. The present study examined the circumstances under which Dutch adolescents were likely to prepare themselves for condom use (buying and carrying). In a sample of 399 secondary school students, including students with and without sexual experience, it was found that intended condom use was not sufficient to ensure that adolescents plan and prepare for condom use. It was found that having the goal of condom use did not necessarily result in preparatory behavior, such as condom buying and condom carrying. The data showed that action-specific social-cognitive factors of preparatory behavior explained preparatory behavior, beyond the decision to use condoms. This suggests that interventions aimed at promoting condom use should focus not only on condom use itself, but should also motivate and encourage adolescents to buy and carry condoms
