Greater understanding of the influences underpinning societal attitudes towards sexuality and disability in this setting, and more extensive communication between health care staff and women with disabilities would facilitate positive action towards improving safe motherhood and reproductive health services for women with disabilities.

BackgroundMalnourished HIV-infected African adults are at high risk of early mortality after starting antiretroviral therapy (ART). We hypothesized that short-course, high-dose vitamin and mineral supplementation in lipid nutritional supplements would decrease mortality.MethodsThe study was an individually-randomised phase III trial conducted in ART clinics in Mwanza, Tanzania, and Lusaka, Zambia. Participants were 1,815 ART-naïve non-pregnant adults with body mass index (BMI) <18.5 kg/m2 who were referred for ART based on CD4 count <350 cells/μL or WHO stage 3 or 4 disease. The intervention was a lipid-based nutritional supplement either without (LNS) or with additional vitamins and minerals (LNS-VM), beginning prior to ART initiation; supplement amounts were 30 g/day (150 kcal) from recruitment until 2 weeks after starting ART and 250 g/day (1,400 kcal) from weeks 2 to 6 after starting ART. The primary outcome was mortality between recruitment and 12 weeks of ART. Secondary outcomes were serious adverse events (SAEs) and abnormal electrolytes throughout, and BMI and CD4 count at 12 weeks ART.ResultsFollow-up for the primary outcome was 91%. Median adherence was 66%. There were 181 deaths in the LNS group (83.7/100 person-years) and 184 (82.6/100 person-years) in the LNS-VM group (rate ratio (RR), 0.99; 95% CI, 0.80–1.21; P = 0.89). The intervention did not affect SAEs or BMI, but decreased the incidence of low serum phosphate (RR, 0.73; 95% CI, 0.55–0.97; P = 0.03) and increased the incidence of high serum potassium (RR, 1.60; 95% CI, 1.19–2.15; P = 0.002) and phosphate (RR, 1.23; 95% CI, 1.10–1.37; P <0.001). Mean CD4 count at 12 weeks post-ART was 25 cells/μL (95% CI, 4–46) higher in the LNS-VM compared to the LNS arm (P = 0.02).ConclusionsHigh-dose vitamin and mineral supplementation in LNS, compared to LNS alone, did not decrease mortality or clinical SAEs in malnourished African adults initiating ART, but improved CD4 count. The higher frequency of elevated serum potassium and phosphate levels suggests high-level electrolyte supplementation for all patients is inadvisable but the addition of micronutrient supplements to ART may provide clinical benefits in these patients.Trial registrationPACTR201106000300631, registered on 1st June 2011.

Summary Objective  Parental HIV infection may affect even those exposed children who remain uninfected. We investigated early growth, an indicator of overall health, of infants born to Zambian mothers recruited for a study of breastfeeding and postpartum health. Methods  HIV‐infected and uninfected women in Lusaka were followed regularly from late pregnancy to 16 weeks postpartum. Infant weight and length were measured at birth, 6 and 16 weeks. Infant HIV status could not be specifically determined in this cohort so comparisons were between all infants of HIV‐uninfected mothers (n = 184) and those infants of HIV‐infected mothers who were known to be alive and showed no clinical evidence of HIV infection at age 2–4 years (n = 85). Results  Most infants were exclusively or predominantly breastfed until 16 weeks. At all time points infants of HIV‐infected mothers tended to have lower weight and length standard deviation (Z) scores (significant for weight at 6 weeks; P = 0.04), even after adjustment for their lower gestational age at birth, compared with infants of uninfected mothers. In multivariate analyses the major factors affecting weight or length at 6 or 16 weeks of age were birth weight or length, and maternal subclinical mastitis, primiparity and weight during pregnancy. Conclusions  Early growth of infants of HIV‐infected mothers is less than that of uninfected mothers, in part associated with subclinical mastitis, and this effect cannot be overcome with intensive support of mothers to follow international recommendations regarding exclusive breastfeeding.

An estimated 60% of all adolescent pregnancies in low-income countries are unintended. The present study was carried out at the university hospital in Lusaka, Zambia over a four-month period in 2005. The aim was to explore experiences of pregnancy loss and to ascertain the girl's contraceptive knowledge and use and their partner's involvement in the pregnancy/abortion. Eighty-seven girls aged 13-19 years admitted to hospital for incomplete abortions were interviewed. Of these girls, 53 (61%) had had a spontaneous abortion and 34 (39%) had undergone an unsafe induced abortion. Significantly more girls with an unsafe induced abortion were single, students, had completed more years in school and were in less stable relationships. Girls' overall contraceptive knowledge and use was low and most pregnancies were unplanned. Partners played a decisive role in terminating pregnancy through unsafe induced abortion. Traditional healers, girls themselves and health professionals were the main abortion providers. Young women's health risks due to unprotected sex and lack of contraceptive services should urgently be addressed. The existence of the abortion law and access to emergency contraception should be better publicized in Zambia.

Choosing an infant feeding mode is complex for human immunodeficiency virus (HIV)-infected African women. We documented infant feeding choices by 811 mothers of infants aged less than 18 months enrolled in the Chilenje Infant Growth, Nutrition and Infection Study of fortified complementary or replacement foods. We also conducted 20 interviews and 4 focus group discussions among women and nurses to explore the issues in depth. Practices of most HIV-infected women did not closely follow national or international guidelines: 26% never initiated breastfeeding, and 55% were not breastfeeding by 6 months post partum. Women of lower socioeconomic status and those not meeting criteria for safe replacement feeding were more likely to initiate breastfeeding, to continue longer and to stop at 6 months when provided with free food within the trial. Most HIV-negative women and women of unknown HIV status continued breastfeeding into the infant's second year, indicating limited 'spillover' of infant feeding messages designed for HIV-infected women into the uninfected population. Qualitative work indicated that the main factors affecting HIV-infected women's infant feeding decisions were the cost of formula, the advice of health workers, influence of relatives, stigma and difficulties with using an exclusive feeding mode. Rapidly changing international recommendations confused both mothers and nurses. Many HIV-infected women chose replacement feeding without meeting criteria to do this safely. Women were influenced by health workers but, for several reasons, found it difficult to follow their advice. The recently revised international HIV and infant feeding recommendations may make the counselling process simpler for health workers and makes following their advice easier for HIV-infected women.

The study foods improved hemoglobin concentrations without reducing breast milk intake and may be used to improve the nutritional status of infants in developing countries.

Subclinical mastitis, defined as raised milk sodium/potassium (Na/K) ratio, is associated with poor infant growth and, among HIV-infected women, with increased milk HIV viral load. We conducted a longitudinal cohort study in Lusaka, Zambia, in order to investigate the relative importance of several potential causes of subclinical mastitis: maternal infection, micronutrient deficiencies and poor lactation practice. Women (198 HIV-infected, 189 HIV-uninfected) were recruited at 34 weeks' gestation and followed up to 16 weeks postpartum for collection of information on their health, their infant's health, infant growth and infant feeding practices. Milk samples were collected from each breast at 11 postpartum visits and blood at recruitment and 6 weeks postpartum. The geometric mean milk Na/K ratio and the proportion of women with Na/K ratio > 1.0 in one or both breasts were significantly higher among HIV-infected than among uninfected women. Other factors associated with the higher mean Na/K ratio in univariable analyses were primiparity, high maternal alpha(1)-acid glycoprotein (AGP) at 6 weeks, maternal overall morbidity and specific breast symptoms, preterm delivery, low infant weight or length, infant thrush and non-exclusive breast feeding. In multivariable analyses, primiparity, preterm delivery, breast symptoms, HIV status and raised AGP were associated with the raised Na/K ratio. Thus the main factors associated with subclinical mastitis that are amenable to intervention are poor maternal overall health and breast health. The impact of improved postpartum health care, especially management of maternal infections and especially in primiparous women, on the prevalence of subclinical mastitis and its consequences requires investigation.

BackgroundEarly growth and health of HIV-exposed, uninfected (HEU) children is poorer than that of their HIV-unexposed, uninfected (HUU) counterparts but there is little information about longer term effects of early HIV exposure. We previously recruited two cohorts of HEU and HUU Zambian infants and documented the poorer infant growth and health of the HEU compared to the HUU children. We followed up HEU and HUU children from these cohorts when they were school-aged and compared their growth, health, biochemical markers of acute or chronic disease, and school grades.MethodsWe recruited 111 HEU and 279 HUU children aged 6–12 years. We measured anthropometry, determined health by questionnaire and clinical examination, viewed the child’s most recent school report, and measured blood pressure, haemoglobin (Hb), HbA1c, glucose, cholesterol, and C-reactive protein (CRP).ResultsAnthropometric measures were lower among HEU than HUU children, significantly so for hip circumference (age- and sex-adjusted difference −1.74 cm; 95 % confidence interval (CI) -3.24, −0.24; P = 0.023) and mid-upper-arm circumference (adjusted difference −0.63 cm, 95 % CI −1.23, −0.04; P = 0.037) and with borderline effects for body mass index, thigh circumference and subscapular skinfolds. HEU children had significantly lower total, trunk, and limb fat percentages. All anthropometric and body composition differences became non-significant after adjustment for sociodemographic variables which differed between HEU and HUU children. More HEU than HUU children reported minor illnesses and were prescribed medication at the time of visit. There were no differences in biochemical markers between groups. HEU children had lower math grades than HUU children even after adjustment for socioeconomic variables.ConclusionsAlthough HEU children were smaller and had lower percent fat than HUU children, this appeared to be due mainly to their poorer socioeconomic status. Reasons for lower school grades require further research.Electronic supplementary materialThe online version of this article (doi:10.1186/s12887-015-0386-8) contains supplementary material, which is available to authorized users.
