Uptake of interventions is nonrandomly distributed\r\nacross populations. Such inequality is socially patterned and reinforced\r\nby homophily arising from both social selection (becoming friends with\r\nsimilar people) and influence (becoming similar to friends).\r\nMethods: We conducted a narrative review to describe how social\r\nnetwork analysis methods—including egocentric, sociocentric, and\r\nrespondent-driven sampling designs—provide tools to measure key\r\npopulations, to understand how epidemics spread, and to evaluate\r\nintervention take-up.\r\nResults: Social network analysis–informed designs can improve\r\nintervention effectiveness by reaching otherwise inaccessible populations. They can also improve intervention efficiency by maximizing\r\nspillovers, through social ties, to at-risk but susceptible individuals.\r\nSocial network analysis–informed designs thus have the potential to be\r\nboth more effective and less unequal in their effects, compared with\r\nsocial network analysis–naïve approaches. Although social network\r\nanalysis-informed designs are often resource-intensive, we believe\r\nthey provide unique insights that can help reach those most in need of\r\nHIV prevention and treatment interventions.\r\nConclusion: Increased collection of social network data during\r\nboth research and implementation work would provide important\r\ninformation to improve the roll-out of existing studies in the present\r\nand to inform the design of more data-efficient, social network\r\nanalysis–informed interventions in the future. Doing so will improve\r\nthe reach of interventions, especially to key populations, and to\r\nmaximize intervention impact once delivered."^^<http://www.w3.org/2001/XMLSchema#string> .
