A role for health communication in the continuum of HIV care, treatment, and prevention.

Abstract:Health communication has played a pivotal role in HIV prevention efforts since the beginning of the epidemic. The recent paradigm of combination prevention, which integrates behavioral, biomedical, and structural interventions, offers new opportunities for employing health communication approaches across the entire continuum of care. We describe key areas where health communication can significantly enhance HIV treatment, care, and prevention, presenting evidence from interventions that include health communication components. These interventions rely primarily on interpersonal communication, especially individual and group counseling, both within and beyond clinical settings to enhance the uptake of and continued engagement in care. Many successful interventions mobilize a network of trained community supporters or accompagnateurs, who provide education, counseling, psychosocial support, treatment supervision, and other pragmatic assistance across the care continuum. Community treatment supporters reduce the burden on overworked medical providers, engage a wider segment of the community, and offer a more sustainable model for supporting people living with HIV. Additionally, mobile technologies are increasingly seen as promising avenues for ongoing cost-effective communication throughout the treatment cascade. A broader range of communication approaches, traditionally employed in HIV prevention efforts, that address community and sociopolitical levels through mass media, school- or workplace-based education, and entertainment modalities may be useful to interventions seeking to address the full care continuum. Future interventions would benefit from development of a framework that maps appropriate communication theories and approaches onto each step of the care continuum to evaluate the efficacy of communication components on treatment outcomes.

Using social and behavior change communication to increase HIV testing and condom use: the Malawi BRIDGE Project

While overall HIV prevalence in Malawi has decreased, it is still high in the southern region of the country. Behavioral prevention activities are crucial to continue the reduction in HIV prevalence. Behavior change is influenced by many factors. Previous work indicates knowledge about HIV transmission, self-efficacy to protect oneself from exposure, and accurate risk perception of ones susceptibility all impact sexual behavior. The current study looks at the effects of a behavior change communication program in Malawi called the BRIDGE II Project on psychosocial and behavioral variables. The program sought to address barriers to individual action and confront societal norms related to sexual risk behavior through a mix of community-based activities and mass media messages delivered through local radio stations. Using cohort data (n = 594), we examined the effect of BRIDGE exposure on three variables that affect HIV behaviors: knowledge, self-efficacy, and risk perception, as well as two behavioral outcomes: HIV testing and condom use at last sex. Data were collected at baseline and for a midterm evaluation. Regression analyses showed exposure to BRIDGE was significantly associated with knowledge level (β = 0.20, p < .001) and self-efficacy (β = 0.35, p < .001) at midterm when controlling for baseline scores, but not risk perception. Psychosocial variables did not show a significant relationship to either behavioral outcome. However, program exposure was a significant predictor of both HIV testing in the past year (odds ratio [OR] = 1.40, p < .001) and condom use at last sex (OR = 1.26, p < .05). This study suggests such a communication intervention may play an important role in not only affecting HIV-related behaviors themselves, but also critical factors that affect HIV behaviors, including knowledge and self-efficacy. It is recommended that communication efforts around HIV risk reduction be increased.

Descriptive and injunctive norms related to concurrent sexual partnerships in Malawi: implications for HIV prevention research and programming

Concurrent sexual partnerships are hypothesized to be a contributing factor to Malawis HIV epidemic. As social norms influence health behavior and have been found to influence sexual behavior, the purpose of this study was to explore two types of norms, descriptive and injunctive norms, toward concurrent sexual partnerships in Malawi. Data from 40 focus group discussions and 20 in-depth interviews conducted in five districts in Malawi, which included 318 participants aged 18-55 years, were analyzed. Participants perceived that concurrent sexual partnerships were extremely common, and believed that very few individuals in their communities were not in concurrent sexual partnerships. However, participants perceived that others in their communities heavily disapproved of concurrent sexual partnerships outside of polygamy, as polygamy was viewed as an acceptable type of partnership because it was conducted in the open. Participants asserted that there were no traditional practices that promoted concurrent sexual partnerships, and perceived that those that engaged in the behavior were for the most part stigmatized by community members. Further research is needed to obtain a thorough understanding of the way in which the perceived actions and beliefs of peers influence the beliefs, feelings and actions of individuals to strengthen HIV programming efforts in the region.

Elevated alcohol and sexual risk behaviors among young Thai lesbian/bisexual women

BACKGROUND Little empirical data have been published about drinking or sexual behaviors among Thai lesbians. We examine the association of sexual identity with established indicators of alcohol- and sexual-related health behaviors among female bar patrons. METHODS We conducted a cross-sectional study among women (N=121) aged 18-24 who frequented popular drinking establishments in Chiang Mai, Thailand. We used general linear modeling techniques to estimate associations between sexual identity and positive alcohol expectancy, harmful drinking, age at sexual debut, and number of lifetime sexual partners. RESULTS Nearly one-third of women aged 18-24 recruited from Chiang Mai drinking venues identified as lesbian/bisexual. As compared to their heterosexual counterparts, lesbian/bisexuals reported higher positive alcohol expectancy scores, more harmful drinking, earlier age at sexual debut, and higher number of lifetime sexual partners. In adjusted models, lesbian/bisexual identity was associated with higher positive alcohol expectancy (β=1.94 points; 95% CI: 0.75, 3.13), earlier age at sexual debut (β=-0.85 years; 95% CI: -1.46, -0.23), and higher number of lifetime sexual partners (rate ratio=1.70; 95% CI: 1.22, 2.37). CONCLUSION Lesbian/bisexual women in this study engaged in multiple behaviors that are potentially harmful to health, which may in turn place this group at heightened risk for alcohol abuse and sexually transmitted infections in Thailand. The clustering of alcohol- and sexual-related risk behaviors, and its consequences for health outcomes in this population, should be explored in future research and may be an important point of intervention.

Leveraging the Power of Knowledge Management to Transform Global Health and Development

Good knowledge is essential to prevent disease and improve health. Knowledge management (KM) provides a systematic process and tools to promote access to and use of knowledge among health and development practitioners to improve health and development outcomes. KM tools range from publications and resources (briefs, articles, job aids) and products and services (websites, eLearning courses, mobile applications), to training and events (workshops, webinars, meetings) and approaches and techniques (peer assists, coaching, after-action reviews, knowledge cafés).

Talking about sex in Malawi: toward a better understanding of interpersonal communication for HIV prevention.

The generalised AIDS epidemic in Malawi presents many challenges. As communication and advice from parents, peers, and partners are important factors in influencing sexual behaviour, understanding communication may provide insights into behaviour change programming. This mixed-method study used a household survey (n=1812) and 15 focus group discussions from the southern districts of Malawi to explore communication about sex and sexuality. Quantitative study findings point to the idea that self-efficacy, perceived benefits, and injunctive norms about talking about condom use are important factors influencing intentions to discuss condom use with partners. Qualitative study findings found that communication regarding sex between parents and children, partners, and peers was not common, and when there was communication, messages about sex focused on negative consequences of sexual activity. In Malawi, there is a need to increase efficacy in talking about sex and protective sexual behaviours, including condom use. Interventions should include components to increase communication skills, shift norms about sexual communication, and provide alternative mechanisms for individuals to gather pertinent information regarding their sexual behaviour.

Informal alcohol in Malawi: Stakeholder perceptions and policy recommendations

Through the eyes of those involved in the alcohol policy-making process in Malawi, we explored the role of informal (non-commercial) alcohol in rural communities, its harmful effects, and implications for appropriate national policy. Harms included early drinking initiation, violence, and sexual risk exposure. Informants suggested that policy should address informal alcohol’s content, selling times, and easy access. Because most informal alcohol producers are women who rely upon sales for subsistence, policies must avoid limiting women’s economic opportunities while protecting community health.

Treatment-as-Prevention in AIDS Control: Why Communication Still Matters

Treatment-as-prevention is a term used to describe an HIV prevention method that uses antiretroviral treatment to minimize the chance of HIV transmission, with the idea that treatment can decrease the viral load of those infected to a level where transmission risk is minimal. However, for treatment-as-prevention to be a success, individuals must get tested, know their status, seek care, and adhere to their antiretroviral regimen. Communication plays a role in each of these steps, as communication can be used to create demand for health-seeking behavior and as a means to increase quality and support on the supply side, at the clinic and community level. From the demand side, communication has played a role in convincing people to get tested and obtain their results, in ensuring treatment access, linking those infected to care, and addressing stigmatizing attitudes that may prevent individuals from taking these actions. On the supply side, communication has been shown to mobilize community care and support and increase the quality of patient-provider interaction, which in turn can improve adherence. Finally, communication has played an integral role in structural issues related to treatment-as-prevention, including the assurance of adequate supplies, including HIV testing kits, anti-retrovirals, and condoms.

Alcohol consumption among high-risk Thai youth after raising the legal drinking age

OBJECTIVE Methamphetamine and alcohol are the leading substances abused by Thai youth. In 2008 the government passed laws that limited alcohol availability and increased the legal drinking age from 18 to 20. We assessed whether the law reduced drinking among methamphetamine-using 18-19 year olds in Chiang Mai. METHOD The study compares drinking patterns among methamphetamine smokers aged 18-19 years (n=136) collected prior to the legal changes, to a comparable post-law sample (n=142). Statistical tests for differences between the pre- and post-law samples on problem drinking and recent drinking frequency and drunkenness were conducted. Logistic regression modeled the relative odds of frequent drunkenness, controlling for demographic characteristics. RESULTS A high prevalence of problematic drinking was present in both samples, with no difference detected. The post-law sample reported a significantly higher median days drunk/month (9 vs. 4, p≤0.01); in adjusted analysis, frequent drunkenness (>5.5 days/month) was more common in the post-law compared to pre-law period in the presence of other variables (AOR: 2.2; 95%CI: 1.3, 3.9). Post-law participants demonstrated a low level of knowledge about the laws components. CONCLUSIONS The study suggests that the new laws did not reduce drinking among high-risk, methamphetamine-smoking 18-19 year olds; rather, the post-law period was associated with increased drinking levels. The data indicate that the law is not reaching high-risk under-aged youth who are at risk of a number of deleterious outcomes as a result of their substance use.

Communicating About Vaccines in a Fact-Resistant World

The continued success of vaccines, one of the most effective public health interventions, depends on high rates of acceptance. Vaccine refusal in the United States has increased since the late 1990s.1 This trend has coincided with an increase in vaccine safety concerns. Such concerns result from easy recall of adverse events, misinformation, and human tendency to poorly judge probabilities. When a significant proportion of the US population is impervious to scientific facts, such as belief in human-induced climate change, it is difficult to communicate vaccine-related information to patients. Parent-physician communication in such conditions is challenging and, if done improperly, may worsen the problem. Although the evidence base for vaccinerelated communications is still emerging, we present developments in social and behavioral communication, behavioral economics, social psychology, and persuasion theory to guide productive vaccine discussions in the clinic.
