Stunted Growth Is Associated With Dyslipidemia in Young Adults With Perinatal HIV Infection

Abstract

Background: HIV increases the risk of atherosclerosis and cardiovascular diseases (CVD). This risk maybe even higher in adult survivors of perinatal HIV infection because of prolonged exposure to HIV and its treatments. Nutritional deprivation in early life may further increase CVD risk. Setting: Botswana-Baylor Children's Clinical Centre of Excellence, Gaborone. Methods: This study examined dyslipidemia in 18- to 24-year olds with perinatally-acquired HIV with and without linear growth retardation (“stunting”). Anthropometry and lipid profiles were measured following a minimum 8-hour fast. Stunting was defined by a height-for-age z-score of <2 SDs below the mean. Dyslipidemia was defined by non–high-density lipoprotein cholesterol (HDL-C) of ≥130 mg/dL, low-density lipoprotein cholesterol (LDL-C) of ≥100 mg/dL, or HDL of <40 mg/dL for male subjects and <50 mg/dL for female subjects. We used logistic regression to determine whether dyslipidemia was associated with stunting while adjusting for demographic and HIV treatment variables. Results: Of 107 young adults (46 males; 61 females) enrolled, 36 (33.6%) were stunted. Prevalence of dyslipidemia was 11.2%, 24.3%, and 65.4% for high non-HDL-C, high LDL-C, and low HDL-C, respectively. In univariable analysis, being stunted was associated with elevated LDL-C (odds ratio [OR], 2.52; 95% confidence interval [CI] =1.02 to 6.25) but not with elevated non-HDL-C (OR = 2.17; 95% CI: = 0.65 to 7.28) or with low HDL-C (OR = 0.75; 95% CI: = 0.33 to 1.73). The association between stunting and elevated LDL-C (OR = 4.40; 95% CI: = 1.49 to 12.98) remained significant after controlling for measured confounders. Conclusion: Dyslipidemia was common among perinatally HIV-infected youth and those with evidence of early nutritional deprivation who were more likely to have elevated LDL-C.
