While multiple lab indicators exist for monitoring measures of VL, research on clustering historical/longitudinal VL measures is limited. Analyzing longitudinal VL patterns rather than aggregated measures offers deeper insights into HIV status. This study uses functional data clustering to classify longitudinal VL patterns and characterize each cluster by demographics, comorbidities, social behaviors, and CD4 count. <b>Methods:</b> Adult PWH diagnosed from 2005 to 2015 in South Carolina with a 5-year minimum follow-up were included. We compared functional principal component analysis (FPCA), K-means, hierarchical clustering, and Gaussian mixture models for classification and found FPCA yielded the best results. ANOVA was used to compare VL characteristics, demographics, comorbidities, substance uses, and longitudinal CD4 count across clusters. <b>Results:</b> Results obtained from FPCA could best distinguish the characteristics and patterns into four clusters. A total of 5916 PWH were grouped into long-term VS group (Cluster 1, 17.3%), short-term VS group (Cluster 2, 29.8%), suboptimal VS group (Cluster 3, 28.3%), and viral failure group (Cluster 4, 24.9%). In the long-term VS group with an average of 11-year follow-up, PWH displayed sustained VS (95.3%) and lower mean CD4 count (95.3%) than other clusters.

As a result, this study was conducted to evaluate the prevalence of overweight and obesity and its associated factors among PLWH on dolutegravir (DTG)- and efavirenz (EFV)-based therapies. <b>Methods:</b> An institution-based comparative cross-sectional study was carried out from June 30, 2021, to August 30, 2021.

Thus, the aim of this study was to investigate variances in body weight and blood lipid levels at two distinct timepoints-baseline and 6-month post-DTG initiation. <b>Methods:</b> We conducted this study between November 2021 and April 2023 among ART-naïve individuals initiating a DTG-based regimen.
