AbstractObjectiveThe present paper examines dietary intake and body composition in antiretroviral (ARV)-naïve HIV-positive compared with HIV-negative South African women, as well as the impact of disease severity on these variables.DesignBaseline data from a longitudinal study assessing bone health in HIV-negative and HIV-positive premenopausal South African women over 18 years of age were used. Anthropometry and body composition, measured by dual energy X-ray absorptiometry, were analysed together with dietary intake data assessed using an interviewer-based quantitative FFQ.SettingSoweto, Johannesburg, South Africa.SubjectsBlack, urban South African women were divided into three groups: (i) HIV-negative (HIV−; n 98); (ii) HIV-positive with preserved CD4 counts (HIV+ non-ARV; n 74); and (iii) HIV-positive with low CD4 counts and due to start ARV treatment (HIV+ pre-ARV; n 75).ResultsThe prevalence of overweight and obesity was high in this population (59 %). The HIV+ pre-ARV group was lighter and had a lower BMI than the other two groups (all P < 0·001). HIV+ pre-ARV women also had lower fat and lean masses and percentage body fat than their HIV− and HIV+ non-ARV counterparts. After adjustment, there were no differences in macronutrient intakes across study groups; however, fat and sugar intakes were high and consumption of predominantly refined food items was common overall.ConclusionHIV-associated immunosuppression may be a key determinant of body composition in HIV-positive women. However, in populations with high obesity prevalence, these differences become evident only at advanced stages of infection.

South African women have a high rate of cervical cancer cases, but there are limited data on human papillomavirus (HPV) genotypes in cervical intraepithelial neoplasia (CIN) in the Eastern Cape province, South Africa. A total of 193 cervical specimens with confirmed CIN from women aged 18 years or older, recruited from a referral hospital, were tested for HPV infection. The cervical specimens, smeared onto FTA cards, were screened for 36 HPV types using an HPV direct flow kit. HPV prevalence was 93.5% (43/46) in CIN2 and 96.6% (142/147) in CIN3. HIV-positive women had a significantly higher HPV prevalence than HIV-negative women (98.0% vs. 89.1%, p = 0.012). The prevalence of multiple types was significantly higher in HIV-positive than HIV-negative women (p = 0.034). The frequently detected genotypes were HPV35 (23.9%), HPV58 (23.9%), HPV45 (19.6%), and HPV16 (17.3%) in CIN2 cases, while in CIN3, HPV35 (22.5%), HPV16 (21.8%), HPV33 (15.6%), and HPV58 (14.3%) were the most common identified HPV types, independent of HIV status. The prevalence of HPV types targeted by the nonavalent HPV vaccine was 60.9% and 68.7% among women with CIN2 and CIN3, respectively, indicating that vaccination would have an impact both in HIV-negative and HIV-positive South African women, although it will not provide full protection in preventing HPV infection and cervical cancer lesions.

AbstractObjectiveTo investigate the impact of fortification by comparing food records and selected biochemical indicators of nutritional status pre- and post-fortification.DesignMean intake from 24 h recalls (n 142) was compared with the Estimated Average Requirement (EAR) to determine the proportion with inadequate intake. In a subsample (n 34), diet and serum retinol, folate, ferritin and Zn were compared pre- and post-fortification for fortified nutrients vitamin A, thiamin, riboflavin, niacin, folic acid, Fe and Zn.SettingSouth Africa.SubjectsBreast-feeding women (ninety-four HIV-infected, forty eight HIV-uninfected) measured at ∼6, 14, 24 weeks, and 9 and 12 months postpartum.ResultsPre-fortification, >80 % of women did not meet the EAR for vitamins A, C, D, thiamin, riboflavin, niacin, B6, B12 and folate and minerals Zn, iodine and Ca. Dietary intake post-fortification increased for all fortified nutrients. In post-fortification food records, >70 % did not meet the EAR for Zn and vitamins A, riboflavin and B6. Serum folate and Zn increased significantly post-fortification (P < 0·001 for both), with no change in ferritin and a reduction in retinol. Post-fortification marginal/deficient folate status was reduced (73·5 % pre v. 3·0 % post; P < 0·001), as was Zn deficiency (26·5 % pre v. 5·9 % post; P < 0·05). Pre- and post-fortification, >93 % were retinol replete. There was no change in Fe deficiency (16·7 % pre v. 19·4 % post; P = 0·728).ConclusionsMicronutrient intake improved with fortification, but >70 % of lactating women did not meet the EAR for Zn, vitamins A, riboflavin and B6. Although 100 % exceeded the EAR for Fe after fortification, Fe status did not improve.

ObjectiveTo estimate the prevalence and describe the patterns of concurrent human papillomavirus (HPV) and STIs and associated factors among HIV-negative young Western Cape, South African women participating in the Efficacy of HPV Vaccine to Reduce HIV Infection (EVRI) trial.MethodsHIV-negative women aged 16–24 years old were enrolled in the EVRI trial (NCT01489527) and randomised to receive the licensed four-valent HPV vaccine or placebo. At study entry, participants were clinically evaluated for five STIs: herpes simplex virus type 2 (HSV-2), chlamydia, gonorrhoea, syphilis and disease-causing HPV genotypes (6/11/16/18/31/33/35/39/45/51/52/56/58/59/68). Demographic and sexual history characteristics were compared among women with STI co-infections, single infection and no infection using Pearson χ2 and Mann-Whitney tests. ORs were calculated to evaluate factors associated with STI co-infection prevalence.ResultsAmong 388 young women, STI co-infection prevalence was high: 47% had ≥2 concurrent STIs, 36% had a single STI and 17% had none of the five evaluated STIs. HPV/HSV-2 (26%) was the most prevalent co-infection detected followed by HPV/HSV-2/Chlamydia trachomatis (CT) (17%) and HPV/CT (15%). Co-infection prevalence was independently associated with alcohol use (adjusted OR=2.01, 95% CI 1.00 to 4.06) and having a sexual partner with an STI (adjusted OR=6.96, 95% CI 1.53 to 30.08).ConclusionsAmong high-risk young women from underserved communities such as in Southern Africa, a multicomponent prevention strategy that integrates medical and behavioural interventions targeting both men and women is essential to prevent acquisition of concurrent STI infections and consequent disease.Trial registration numberNCT01489527; Post-results.
