Body composition in adults infected with human immunodeficiency virus in Khon Kaen, Thailand

A cross-sectional study of 77 patients infected with human immunodeficiency virus (HIV) in Khon Kaen, Thailand examined association of nutritional status with active opportunistic infections (AOIs)/HIV status and assessed degree of correlation between bioelectrical impedance analysis (BIA) and anthropometry. Many patients (41.3%) were malnourished using World Health Organization criteria for underweight, and malnutrition was associated with AOI status. Unconditional odds ratios (P < 0.05) for AOI as opposed to no AOI were 4.57 for underweight, 9.87 for severe underweight, 2.55 for triceps < 10th percentile, and 5.22 for mid-arm circumference < 10th percentile. Body fat composition from BIA, anthropometry, and body mass index were moderate to highly correlated (P < 0.001), with the highest correlation between BIA and subscapular skinfold (r = 0.86) and the lowest between BIA and triceps skinfold (r = 0.54). Insights were gained about relative value of using various measurements to assess nutritional status of HIV-infected populations.
