Metabolic Profile of HIV-Infected Women in Mangaung; Free State

Objective: To determine the biochemical nutritional status of HIV-infected women in Mangaung. Design: Cross-sectional. Setting: The community of Mangaung; Free State; South Africa. Subjects: A representative group of 500 black women (25-44 years) was selected randomly to participate. Outcome measures: Biochemical analyses were performed for total lymphocytes; serum protein; serum albumin; plasma fibrinogen; serum insulin; serum glucose; serum triglycerides and serum cholesterol using standard methodology. Values were compared to standard references; and between HIV-infected and HIV-uninfected women. Results: After screening for eligibility; 488 women qualified. Sixty-one per cent of the younger women (25-34 years) and 38of the older women (35-44 years) were HIV-infected. HIV-infected women had significantly lower median blood values for total lymphocytes (p = 0.0001 and p = 0.02 for younger and older group respectively) and serum albumin (p = 0.0001 for both age groups); but significantly higher median concentrations of serum protein (p = 0.0001 for both age groups) than uninfected women. Plasma fibrinogen and serum insulin concentrations were significantly lower in HIV-infected younger women than in their uninfected counterparts (p = 0.002 for both parameters). Older HIV-infected women had significantly lower total serum cholesterol values (p = 0.01) than older HIV-uninfected women. Serum glucose and serum triglycerides did not differ significantly between HIV-infected and HIV-uninfected women. Conclusions: The results indicate a possible impact of HIV infection on serum protein and serum albumin; which may adversely affect biochemical nutritional status and the course of HIV progression. Future research into the causes and possible treatment of metabolic changes in women in this community should be prioritised

Micronutrient Intake of HIV-Infected Women in Mangaung; Free State

Background. Poor nutritional status in HIV/AIDS patients can affect immune function profoundly; leading to faster disease progression and earlier death.Objective. To determine the micronutrient intake of HIV-infected women in Mangaung.Design and setting. A cross-sectional study was undertaken in Mangaung; Bloemfontein; Free State.Subjects and methods. A representative group of 500 pre-menopausal women (25 - 44 years) was randomlyselected to participate in the study. Micronutrient intake was determined using a Quantitative Food FrequencyQuestionnaire (QFFQ). Median micronutrient intakes were compared with the Recommended Dietary Allowance(RDA) or Adequate Intake (AI) values. The prevalence of women with intakes 67of the RDA or AI was calculated. Median micronutrient intakes were compared between HIV-infected and uninfected women using non-parametric 95confidence intervals (CIs) and the Mann-Whitney test.Results. Sixty-one per cent of women in the younger age group (25 - 34 years) and 38of older women (35 - 44 years) were HIV-infected. Between 46.6and 70.7of all women consumed 67of the RDA or AI for calcium;total iron; selenium; folate and vitamin C. At least 25of HIV-infected women did not meet either the RDA or the AI for vitamins A; D and E. Younger HIV-infected women had significantly higher intakes of calcium (p = 0.046);phosphorus (p = 0.04); potassium (p = 0.04); vitamin B12 (p = 0.01); vitamin D (p = 0.03) and vitamin E (p = 0.04)than their HIV-uninfected counterparts. Older HIV-infected women had significantly lower intakes of haem iron (p = 0.03); non-haem iron (p = 0.04) and selenium (p = 0.04) than their HIV-uninfected counterparts.Conclusions. Insufficient micronutrient intakes are common in both HIV-infected and uninfected women. A well-balanced diet and micronutrient supplementation seem warranted to ensure optimal health and survival; particularly in HIV-infected women
