Maternal nutritional status predicts adverse birth outcomes among HIV-infected rural Ugandan women receiving combination antiretroviral therapy.

ABSTRACT: Maternal nutritional status is an important predictor of birth outcomes, yet little is known about the nutritional status of HIV-infected pregnant women treated with combination antiretroviral therapy (cART). We therefore examined the relationship between maternal BMI at study enrollment, gestational weight gain (GWG), and hemoglobin concentration (Hb) among 166 women initiating cART in rural Uganda.Prospective cohort.HIV-infected, ART-naïve pregnant women were enrolled between 12 and 28 weeks gestation and treated with a protease inhibitor or non-nucleoside reverse transcriptase inhibitor-based combination regimen. Nutritional status was assessed monthly. Neonatal anthropometry was examined at birth. Outcomes were evaluated using multivariate analysis.Mean GWG was 0.17 kg/week, 14.6% of women experienced weight loss during pregnancy, and 44.9% were anemic. Adverse fetal outcomes included low birth weight (LBW) (19.6%), preterm delivery (17.7%), fetal death (3.9%), stunting (21.1%), small-for-gestational age (15.1%), and head-sparing growth restriction (26%). No infants were HIV-infected. Gaining <0.1 kg/week was associated with LBW, preterm delivery, and a composite adverse obstetric/fetal outcome. Maternal weight at 7 months gestation predicted LBW. For each g/dL higher mean Hb, the odds of small-for-gestational age decreased by 52%.In our cohort of HIV-infected women initiating cART during pregnancy, grossly inadequate GWG was common. Infants whose mothers gained <0.1 kg/week were at increased risk for LBW, preterm delivery, and composite adverse birth outcomes. cART by itself may not be sufficient for decreasing the burden of adverse birth outcomes among HIV-infected women.Clinicaltrials.gov NCT00993031.

Project description:Lifelong ART is essential to reducing HIV mortality and ending the epidemic, however the interplay between socioeconomic position and long-term outcomes of HIV-infected persons receiving antiretroviral therapy (ART) in sub-Saharan Africa is unknown. Furthering the understanding of factors related to long-term ART outcomes in this important region will aid the successful scale-up of ART programs. We enrolled 559 HIV-infected Ugandan adults starting ART in 2004-2005 at the Infectious Diseases Institute in Kampala, Uganda and followed them for 10 years. We documented baseline employment status, regular household income, education level, housing description, physical ability, and CD4 count. Viral load was measured every six months. Proportional hazard regression tested for associations between baseline characteristics and 1) mortality, 2) virologic failure, and 3) mortality or virologic failure as a composite outcome. Over ten years 23% (n = 127) of participants died, 6% (n = 31) were lost-to-follow-up and 23% (107/472) experienced virologic treatment failure. In Kaplan-Meier analysis we observed an association between employment and mortality, with the highest cumulative probability of death occurring in unemployed individuals. In univariate analysis unemployment and disease severity were associated with mortality, but in multivariable analysis the only association with mortality was disease severity. We observed an association between higher household income and an increased incidence of both virologic failure and the combined outcome, and an association between self-employment and lower incidence of virologic failure and the combined outcome when compared to unemployment. Formal education level and housing status were unrelated to outcomes. It is feasible to achieve good ten-year survival, retention-in-care, and viral suppression in a socioeconomically diverse population in a resource-limited setting. Unemployment appears to be related to adverse 10-year ART outcomes. A low level of formal education does not appear to be a barrier to successful long-term ART.

Project description:OBJECTIVE:Using a summary measure of health inequalities, this study evaluated the distribution of adverse birth outcomes (ABO) and related maternal risk factors across area-level socioeconomic status (SES) gradients in urban and rural Alberta, Canada. DESIGN:Cross-sectional study using a validated perinatal clinical registry and an area-level SES. SETTING:The study was conducted in Alberta, Canada. Data about ABO and related maternal risk factors were obtained from the Alberta Perinatal Health Program between 2006 and 2012. An area-level SES index derived from census data (2006) was linked to the postal code at delivery. PARTICIPANTS:Women (n=3?30?957) having singleton live births with gestational age ?22 weeks. PRIMARY AND SECONDARY OUTCOME MEASURES:We estimated concentration indexes to assess inequalities across SES gradients in both rural and urban areas (CIdxR and CIdxU, respectively) for spontaneous preterm birth (PTB), small for gestational age (SGA), large for gestational age (LGA), gestational hypertension, gestational diabetes, smoking and substance use during pregnancy and pre-pregnancy weight >91?kg. RESULTS:The highest health inequalities disfavouring low SES groups were identified for substance abuse and smoking in rural areas (CIdxR-0.38 and -0.23, respectively). Medium inequalities were identified for LGA (CIdxR-0.08), pre-pregnancy weight >91?kg (CIdxR-0.07), substance use (CIdxU-0.15), smoking (CIdxU-0.14), gestational diabetes (CIdxU-0.10) and SGA (CIdxU-0.07). Low inequalities were identified for PTB (CIdxR-0.05; CIdxU-0.05) and gestational diabetes (CIdxR-0.04). Inequalities disfavouring high SES groups were identified for gestational hypertension (CIdxR+0.04), SGA (CIdxR+0.03) and LGA (CIdxU+0.03). CONCLUSIONS:ABO and related maternal risk factors were unequally distributed across the socioeconomic gradient in urban-rural settings, with the greatest concentrations in lower SES groups of rural areas. Future research is needed on underlying mechanisms driving SES gradients in perinatal health across the rural-urban spectrum.

Project description:BACKGROUND: Long term use of antiretroviral therapy (ART) in persons living with human immunodeficiency virus (PLWHIV) is associated with disturbances in blood lipids which should be monitored. More data on such disturbances are needed in Cameroon to persuade the country program to institute their routine monitoring. We then sought to determine the prevalence and timing of dyslipidaemia in PLWHIV and receiving ART in a predominantly rural Cameroonian setting. METHODS: A cross-sectional study conducted between August and October 2012 in HIV-infected persons aged 15 years or more and receiving first-line ART for at least six months at The Nkongsamba Regional Hospital in Cameroon. Lipid assays were carried out by enzymatic-linked colorimetric methods. A multiple logistic regression model was used to assess for factors related to dyslipidaemia. RESULTS: Included were 114 participants of whom 83 (72.8%) were females. Their median age was 43 years (IQR: 36-51) and their median CD4 count was 436 cells/?l (IQR: 275-585) after a median duration on ART of 36 months (IQR: 12-60). The prevalence of dyslipidaemia was 70.2%. Hypercholesterolaemia was observed in 34 (29.8%) patients. One-third of them had a high LDL-cholesterol level (LDL-c?130 mg/dl). Hypertriglyceridaemia (TG?150 mg/dl) was present in 59 (51.8%) cases. The proportion of patients with a low HDL-cholesterol (HDL-c<40 mg/dl) was 18.4% while those with a ratio of TC/HDL-c?5 were about 16.7%. A duration of 2-4 years on ART (adjusted Odd Ratio, aOR=5.22, 95% CI: 1.43-19.06, p=0.01), current smokers (aOR=15.94, 95% CI: 1.13-225.61, p=0.04) and a concurrent metabolic disease (aOR=12.54, 95% CI: 1.02-153.86, p=0.48) were independently associated with pro-atherogenic LDL-c values. Alcohol users had a more friendly LDL-c profile (aOR=0.24, 95% CI: 0.07-0.74, p=0.01). CONCLUSION: The study has demonstrated a high prevalence of dyslipidaemia in HIV-patients receiving first-line ART in a predominantly rural setting of Cameroon. There is a need for the country HIV program to institute laboratory monitoring of blood lipids in patients over two years on first line ART with a focus on smokers.
