Abstract



Purpose: The aim of this analysis was to evaluate the prevalence and risk factors for HIV-Associated
Lipodystrophy Syndrome (HALS) in the Study to Understand the Natural History of HIV/AIDS in the Era of
Effective Treatment (SUN Study).
Methods: The SUN study is Data collected at baseline was used for this analysis. HALS was defined using
both Fat Mass Ratio in males and females and Lower Limb to Trunk Fat Ratio (LLTFR) in males only.
Univariate analysis was performed using MH test statistics. Multivariate analysis was performed using
Poisson regression to estimate Prevalence Ratios (PR).
Results: Population prevalence was 13% using FMR and 38% using LLTRF to define HALS. In females,
only aerobics and having taken stavudine were significant in the final model. In males, using FMR to
define HALs, risk factors included white non-Hispanic (2.32) and Hispanic (PR 2.49) compared to black
non-Hispanic, decreased adiponectin (2.11), use of testosterone (1.87), current smokers (0.51), having
taken ziduvodine (1.53), having taken stavudine (2.12), and increased age (PR 1.69 per 10 year increase)
were all significant. In males, using LLTRF to define HALS, model was similar but dropped testosterone
and smoking status.
Conclusions: FMR did not provide a useful HALS definition for model building in females, but did appear
to be associated with expected risk factors in males. LLTRF was similar in males, but generally provided
measures of association closer to the null. White non-Hispanic and Hispanic races appear to be at an
increased risk for HALS. Lack of temporal data limits causal interpretation of models, however several
traditional risk factors, such as age and HAART therapy, were confirmed while several new risk
associations, such as race and a seemingly protective effect of current smoking status, were identified.
