Abstract

BACKGROUND AND AIMS

Prior cross-sectional studies have found inconsistent relationships between body mass index (BMI) and disease progression in HIV-infected individuals.

METHODS

Cross-sectional and longitudinal analyses were conducted on data from a sample of 864 HIV-infected men who have sex with men (MSM) obtained from a large, nationally distributed HIV clinical cohort.

RESULTS

Of the 864 HIV-infected MSM, 394 (46%) were of normal weight, 363 (42%) were overweight, and 107 (12%) were obese at baseline. The baseline CD4 count was 493 (standard error [SE] = 9), with viral load (log10) = 2.4 (SE = .04), and 561 (65%) were virologically suppressed. Over time, controlling for viral load, highly active antiretroviral therapy (HAART) adherence, age, and race/ethnicity, overweight and obese HIV-infected men possessed higher CD4 counts than that of normal weight HIV-infected men. Further, overweight and obese men possessed lower viral loads than that of normal weight HIV-infected men.

CONCLUSIONS

For HIV-infected MSM, in this longitudinal cohort study, possessing a heavier than normal BMI is longitudinally associated with improved immunological health.

摘要

背景与目的

既往横断面研究发现,体重指数(BMI)与HIV感染者疾病进展之间的关系并不一致。

方法

对来自一个大型全国性HIV临床队列的864名男男性行为者(MSM)HIV感染者样本的数据进行横断面和纵向分析。

结果

在864名HIV感染的男男性行为者中,394人(46%)基线体重正常,363人(42%)超重,107人(12%)肥胖。基线CD4细胞计数为493(标准误[SE]=9),病毒载量(log10)=2.4(SE=0.04),561人(65%)病毒学抑制。随着时间推移,在控制病毒载量、高效抗逆转录病毒治疗(HAART)依从性、年龄和种族/民族的情况下,超重和肥胖的HIV感染男性的CD4细胞计数高于体重正常的HIV感染男性。此外,超重和肥胖男性的病毒载量低于体重正常的HIV感染男性。

结论

在这项纵向队列研究中,对于HIV感染的男男性行为者,BMI高于正常水平与免疫健康改善在纵向层面相关。
