N1 - Funding Information:
We gratefully acknowledge the Amsterdam Cohort Studies (ACS) on HIV infection, a collaboration between the Public Health Service of Amsterdam, the Amsterdam UMC, Sanquin Blood Supply Foundation, Medical Center Jan van Goyen, and the HIV Focus Center of the DC-Clinics. We furthermore thank their participants, study nurses (Leeann Storey and Samantha de Graaf) and data managers (Ertan Ersan, Dominique Loomans, Linda May, and Gerben Rienk Visser). We also acknowledge Monique Chambon for her contribution to the R-script and interpretation of the network analyses and Anders Boyd for his contribution to the remaining statistical analyses. The Amsterdam Cohort Study is part of the Netherlands HIV Monitoring Foundation and financially supported by the National Institute for Public Health and the Environment, Bilthoven, the Netherlands.

N2 - Biomedical HIV-prevention strategies (BmPS) among men who have sex with men (MSM), such as pre-exposure prophylaxis (PrEP) and viral load sorting (VLS), are essential but relatively new and their uptake gradual. Using an extension of the causal attitude network approach, we investigated which beliefs are related to uptake of PrEP and VLS at each time-point. We included 632 HIV-negative MSM from the Amsterdam Cohort Studies from four data-waves between 2017 and 2019. We estimated weighted, undirected networks for each time-point, where we included pairwise interactions of PrEP and VLS uptake and related beliefs. PrEP use increased from 10 to 31% (p < 0.001), while VLS was reported by 7–10% at each time-point. Uptake of both BmPS was directly related to the perceived positive impact of the strategy on one’s quality of sex life and perceived supportive social norms. Overall network structure differed between time points, specifically in regard to PrEP. At earlier time points, perceptions of efficacy and affordability played an important role for PrEP uptake, while more recently social and health-related concerns became increasingly important.The network structure differed across data-waves, suggesting specific time changes in uptake motives. These findings may be used in communication to increase prevention uptake.
