Background: HIV advocacy programs are partly responsible for the global community's success in reducing the burden of HIV. The rising wave of the global burden of noncommunicable diseases (NCDs) has prompted the World Health Organization to espouse NCD advocacy efforts as a possible preventive strategy. HIV and NCDs share some similarities in their chronicity and risky behaviors, which are their associated etiology. Therefore, pooled evidence on the effectiveness of HIV advocacy programs and ideas shared could be replicated and applied during the conceptualization of NCD advocacy programs. Such evidence, however, has not been systematically reviewed to address the effectiveness of HIV advocacy programs, particularly programs that aimed at changing public behaviors deemed as risk factors.

Objectives: To determine the effectiveness of HIV advocacy programs and draw lessons from those that are effective to strengthen future noncommunicable disease advocacy programs.

Search methods: We searched for evidence regarding the effectiveness of HIV advocacy programs in medical databases: PubMed, The Cumulative Index to Nursing and Allied Health Literature Plus, Educational Resources and Information Center, and Web of Science, with articles dated from 1994 to 2014.

Search criteria. The review protocol was registered before this review. The inclusion criteria were studies on advocacy programs or interventions. We selected studies with the following designs: randomized controlled design studies, pre-post intervention studies, cohorts and other longitudinal studies, quasi-experimental design studies, and cross-sectional studies that reported changes in outcome variables of interest following advocacy programs. We constructed Boolean search terms and used them in PubMed as well as other databases, in line with a population, intervention, comparator, and outcome question. The flow of evidence search and reporting followed the standard Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

Data collection and analysis: We selected 2 outcome variables (i.e., changing social norms and a change in impact) out of 6 key outcomes of advocacy interventions. We assessed the risk of bias for all selected studies by using the Cochrane risk-of-bias tool for randomized studies and using the Risk of Bias for Nonrandomized Observational Studies for observational studies. We did not grade the collective quality of evidence because of differences between the studies, with regard to methods, study designs, and context. Moreover, we could not carry out meta-analyses because of heterogeneity and the diverse study designs; thus, we used a narrative synthesis to report the findings.

Main results: A total of 25 studies were eligible, of the 1463 studies retrieved from selected databases. Twenty-two of the studies indicated a shift in social norms as a result of HIV advocacy programs, and 3 indicated a change in impact. We drew 6 lessons from these programs that may be useful for noncommunicable disease advocacy: (1) involving at-risk populations in advocacy programs, (2) working with laypersons and community members, (3) working with peer advocates and activists, (4) targeting specific age groups and asking support from celebrities, (5) targeting several, but specific, risk factors, and (6) using an evidence-based approach through formative research.

Author conclusions: HIV advocacy programs have been effective in shifting social norms and facilitating a change in impact.

Public health implications: The lessons learned from these effective programs could be used to improve the design and implementation of future noncommunicable disease advocacy programs.

Editor’s notes: This article presents the results of a systematic review to answer a question about the effectiveness of HIV advocacy in changing social norms and changing impact among key populations. The review was conducted to learn from effective HIV advocacy and apply similar strategies for the prevention and reduction of the global burden of non-communicable diseases. The review included quantitative research only. After searching 3320 articles, 25 articles met the inclusion criteria. The HIV advocacy activities reviewed ranged from local and mass campaigns using a variety of media, to social marketing, celebrities, drama, promotional activities and counselling. Changes in social norms were assessed using six specific variables, for example testing behaviour change or HIV-associated stigma. Changes in impact were analysed in two aspects, changes in HIV transmission and in adherence to antiretroviral therapy. The review has found significant evidence of the effect of HIV advocacy on the outcomes of interest. The authors highlight lessons from HIV advocacy that might be useful for future non-communicable diseases advocacy. These included the vital role of peer-educator and of lay members of the community and the involvement of key populations in programmes that focus on them.  In addition, there is a need to tailor programmes to specific (rather than multiple) risks using local and salient evidence.
