Food insecurity is a barrier to prevention of mother-to-child HIV transmission services in Zimbabwe: a cross-sectional study

Associations between food insecurity and child and parental physical, nutritional, psychosocial and economic well-being globally during the first 1000 days: A scoping review

Food insecurity affects billions of individuals annually and contributes to myriad poor health outcomes. Experiences of food insecurity may be particularly harmful during the first 1000 days, but literature on the topic has not been synthesized. We therefore aimed to characterize all available studies examining associations between food insecurity and nutritional, psychosocial, physical and economic well-being among parents and children during this period. We implemented a standardized search strategy across 11 databases. Four researchers screened 10,257 articles, 120 of which met the inclusion criteria. Most studies were conducted in Sub-Saharan Africa (43.3%), followed by North America (20.8%). Studies were primarily quantitative (95.8%), cross-sectional (70.0%) and focused on women (pregnant or post-partum, 48.3%) or women and children (15.8%). Physical health outcomes were the most investigated (n = 87 studies), followed by nutritional (n = 69), psychosocial (n = 35) and economic well-being (n = 2). The most studied associations were between food insecurity and stunting (n = 15), maternal depression (n = 12), child dietary diversity (n = 7) and maternal body mass index (n = 6). The strength of evidence for the observed associations varied across populations as well as within and between examined outcomes. We recommend that future studies recruit more diverse study populations, consider temporality of relationships, use instruments that facilitate cross-site comparisons, measure individual-level food insecurity and outcomes most likely to be impacted by food insecurity, evaluate contextual factors that may modify the effects of food insecurity and employ analytic techniques that permit assessment of causal pathways.

Food Insecurity and Health Outcomes Other than Malnutrition in Southern Africa: A Descriptive Systematic Review

Food insecurity (FI) is one of the major causes of malnutrition and is associated with a range of negative health outcomes in low and middle-income countries. The burden of FI in southern Africa is unknown, although FI continues to be a major public health problem across sub-Saharan Africa as a whole. Therefore, this review sought to identify empirical studies that related FI to health outcomes among adults in southern Africa. Altogether, 14 publications using diverse measures of FI were reviewed. The majority of the studies measured FI using modified versions of the United States Department of Agriculture Household Food Security Survey Module. A wide range in prevalence and severity of FI was reported (18-91%), depending on the measurement tool and population under investigation. Furthermore, FI was mostly associated with hypertension, diabetes, anxiety, depression and increased risk of human immunodeficiency virus (HIV) acquisition. Based on the findings, future research is needed, especially in countries with as yet no empirical studies on the subject, to identify and standardize measures of FI suitable for the southern African context and to inform public health policies and appropriate interventions aiming to alleviate FI and potentially improve health outcomes in the region.

Food insecurity predicts loss to follow-up among people living with HIV in Senegal, West Africa

The goals of this study were to assess retention on antiretroviral therapy (ART) and to identify predictors of loss to follow-up (LTFU) among people living with HIV (PLHIV) in Senegal. HIV-positive individuals presenting for initiation of ART in Dakar and Ziguinchor were enrolled and followed for 12 months. Data were collected using interviews, clinical evaluations, laboratory analyses, chart review, and active patient tracing. Of the 207 individuals enrolled, 70% were female, 32% had no formal education, and 28% were severely food insecure. At the end of the follow-up period, 58% were retained on ART, 15% were deceased, 4% had transferred care, 5% had migrated, and 16% were lost to follow-up. Enrollment in Ziguinchor (OR 2.71 [1.01–7.22]) and severe food insecurity (OR 2.55 [1.09–5.96]) were predictive of LTFU. Sex, age, CD4 count, BMI <18.5, country of birth, marital status, number of children, household size, education, consultation with traditional healers, transportation time, and transportation cost were not associated with LTFU. The strongest predictor of severe food insecurity was lack of formal education (OR 2.75 [1.30–5.80]). Addressing the upstream drivers of food insecurity and implementing strategies to enhance food security for PLHIV may be effective approaches to reduce LTFU and strengthen the HIV care cascade in the region.

The impact of food insecurity on HIV outcomes in Senegal, West Africa: a prospective longitudinal study

Background

Understanding the impact of food insecurity on HIV outcomes is critical for the development and implementation of effective, evidence-based interventions to address food insecurity and improve the HIV care cascade. We conducted a prospective, longitudinal study to determine the impact of food insecurity on HIV outcomes in Senegal, West Africa.

Methods

HIV-infected individuals presenting for care and initiation of ART through the Senegalese National AIDS program in Dakar and Ziguinchor were eligible for enrollment. Data were collected using interviews, clinical evaluations, laboratory analyses, and chart review at enrollment, month 6, and month 12. Logistic regression was used to determine the association between food insecurity and HIV outcomes.

Results

Among the 207 participants in this study, 70% were female and the median age was 37 years. The majority (69%) were food insecure at enrollment, 29% were severely food insecure, and 38% were undernourished. Nearly a third (32%) had no formal education, 23% practiced agriculture, and 40% owned livestock. The median daily food expenditure per person was $0.58. The median round trip transportation time to clinic was 90 min (IQR 30–240). The median cost of transportation to clinic was $1.74. At month 12, 69% were food insecure, 23% were severely food insecure, and 14% were undernourished. At month 12, 43% had not disclosed their HIV status; food insecurity was associated with non-disclosure of HIV-status due to fear of stigmatization and feelings of shame. Severe food insecurity was a strong predictor of loss to follow-up (OR 3.13 [1.08–9.06]) and persistent severe food insecurity was associated with virologic failure (OR 5.14 [1.01–26.29]) and poor adherence to ART 8.00 [1.11–57.57]. Poor nutritional status was associated with poor immunologic recovery (OR 4.24 [1.56–11.47]), virologic failure (OR 3.39 [1.13–10.21]), and death (OR 3.35 [1.40–8.03]).

Conclusion

Severity and duration of food insecurity are important factors in understanding the relationship between food insecurity and HIV outcomes. Our findings highlight the importance of nutritional status, socioeconomic opportunity, and self-stigmatization in the complex pathway between food insecurity and HIV outcomes. Interdisciplinary, multisectoral efforts are needed to develop and implement effective interventions to address food insecurity among people living with HIV.

Maternal HIV and child anthropometric outcomes over time: an analysis of Zimbabwe demographic health surveys

OBJECTIVES

To understand the association between children's anthropometric measures and maternal HIV status in Zimbabwe and to determine whether these relationships changed over time.

DESIGN

Data from Demographic Health Surveys in Zimbabwe rounds 2005, 2010, and 2015 were used to conduct cross-sectional analyses of child anthropometric measures (stunting, underweight, and wasting).

METHODS

Using separate logistic regression models for each of the anthropometric measures, we estimated the adjusted prevalence odds ratio (OR) of stunting, underweight, and wasting in children according to maternal HIV status. Moreover, we evaluated an interaction by survey year to evaluate change over time.

RESULTS

Children of mothers with HIV had 32% greater odds [OR = 1.32, 95% confidence interval (CI) 1.16-1.5] of stunting, 27% greater odds (OR = 1.27, 95% CI 1.1-1.48) of underweight status and 7% greater odds (OR = 1.07, 95% CI 0.81-1.42) of wasting status, than children of mothers without HIV. These associations between maternal HIV status and child undernutrition did not differ by year (P > 0.05 for all interaction terms).

CONCLUSION

In Zimbabwe, having a mother who tested positive for HIV at the time of the survey has been associated with greater child undernutrition over the last two decades with no significant change by survey round. This emphasizes the need for continued programming to address nutritional deficiencies, sanitation, and infectious disease prevention in this high-risk population. The greatest impact of maternal HIV status has been on child stunting and underweight, associated with poor long-term child development.

Disparities in antenatal care service utilization among food secure and food insecure women in Gombora District, Hadiya zone, south Ethiopia

Introduction

little is known about antenatal care (ANC) utilization difference among food secure and food insecure household pregnant women and factors contributing to inequities in antenatal care use in developing country including Ethiopia. To determine the disparities in the utilization of antenatal care that exists between pregnant women in food secure and food insecure household women.

Methods

a community based comparative cross-sectional study was conducted in Gombora District, Hadiya zone, southern Ethiopia. Data were collected from February 25^th to March 25^th, 2015, using a pre-tested structured questionnaire. Pregnant women were selected by a simple random sampling method. The data were entered using EpiData 3.1 and exported to SPSS version 21 for analysis. Multivariate logistic regression analysis was done to compare antenatal care utilization among food secure and insecure household women at 95% confidence interval (CI). Statistical tests were done at a level of significance of p<0.05.

Results

two hundred sixty-seven (34.5%) of the respondents received at least one antenatal care visit on current pregnancy. Forty-nine-point one percent of food secure and 23.3% of food insecure household women utilized ANC from health professionals. Factors associated with antenatal care utilization included being from a food secure household (adjusted odds ratio [aOR]= 2.54; 95%CI: 1.79-3.59), having attained secondary or higher education (aOR=3.76; 95%CI: 2.32-6.1), good level of knowledge of antenatal care (aOR= 2.42; 95%CI 1.34-4.33) and being from a wealthy household (aOR=2.10; 95% CI: 1.34-3.28). Conclusion: this study showed a significant variation in the use of ANC in food secure and food insecure household pregnant women. Interventions to improve ANC utilization should prioritize women from poor socio-economic and low educational background.

Food Insecurity Associated with Attendance to Antenatal Care Among Pregnant Women: Findings from a Community-Based Cross-Sectional Study in Southern Ethiopia

Purpose

Enrollment to antenatal care (ANC) is still not universal in Ethiopia. This study examines whether household food insecurity affects antenatal care attendance or not, as well as other factors associated with antenatal care. As optimal antenatal care is vital for the improvement of maternal and child health, the study will contribute to the efforts in improving maternal and child health.

Patients and Methods

A community-based cross-sectional study was conducted among 707 pregnant women at or above 3 months of self-reported pregnancy in Southern Ethiopia. Multi-stage sampling was employed to obtain the study units. Data were collected using an interviewer-administered structured questionnaire. Logistic regression analysis was conducted to identify the independent factors associated with study outcome.

Results

Out of a total of 707 study subjects, the majority (71%) of the study women visited a health facility for ANC service. The odds of ANC use was lower for women who were not in marital union (adjusted odds ratio (AOR)=0.39, 95% confidence interval (CI)=0.16-0.97), and those from food insecure households (AOR=0.50, 95% CI=0.32-0.79). ANC attendance was higher for women from high socio-economic status (AOR=2.62, 95% CI=1.29-5.29), with planned pregnancy (AOR=1.82, 95% CI=1.16-2.85) and a perceived risk from danger signs (AOR=4.32, 95% CI=1.60-11.67).

Conclusion

While the overall ANC use was high, women experiencing food insecurity and those with unplanned pregnancy were having lower odds of ANC attendance among others. Interventions targeting at enhancing women's attendance to ANC service might be realized through commitment from the agriculture, economic, as well as health sectors by increasing productivity and providing special attention to women in the pre-pregnancy and pregnancy period. Moreover, educating women so that they can recognize that every pregnancy is risky and promotion of family planning to reduce unplanned pregnancy could improve attendance to the ANC service.

Brief Report: Improving Early Infant Diagnosis Observations: Estimates of Timely HIV Testing and Mortality Among HIV-Exposed Infants

Background:

Improving efforts toward elimination of mother-to-child transmission of HIV requires timely early infant diagnosis (EID) among all HIV-exposed infants, but the occurrence of timely EID and infant survival may be underascertained in routine, facility-bound program data.

Methods:

From March 2015 to May 2015, we traced a random sample of HIV-positive mother and HIV-exposed infant pairs lost to follow-up for EID in facility registers in Zimbabwe. We incorporated updated information into weighted survival analyses to estimate incidence of EID and death. Reasons for no EID were surveyed from caregivers.

Results:

Among 2651 HIV-positive women attending antenatal care, 1823 (68.8%) infants had no documented EID by 3 months of age. Among a random sample of 643 (35.3%) HIV-exposed infants lost to follow-up for EID, vital status was ascertained among 371 (57.7%) and updated care status obtained from 256 (39.8%) mothers traced. Among all HIV-infected mother–HIV-exposed infant pairs, weighted estimates found cumulative incidence of infant death by 90 days of 3.9% (95% confidence interval: 3.4% to 4.4%). Cumulative incidence of timely EID with death as a competing risk was 60%. The most frequently cited reasons for failure to uptake EID were “my child died” and “I didn't know I should have my child tested.”

Conclusions:

Our findings indicate uptake of timely EID among HIV-exposed infants is underestimated in routine health information systems. High, early mortality among HIV-exposed infants underscores the need to more effectively identify HIV-positive mother–HIV exposed infant pairs at high risk of adverse outcomes and loss to follow-up for enhanced interventions.

Perinatal Food Insecurity and Postpartum Psychosocial Stress are Positively Associated Among Kenyan Women of Mixed HIV Status

Stress and food insecurity (FI) are associated with poor perinatal and HIV outcomes. We hypothesized that FI would increase postpartum stress among women in Kenya, and that the impact would be greater in women with HIV. Among 371 pregnant women, we identified latent FI trajectories across the perinatal period, and estimated their association with postpartum stress. Stress metrics included the Perceived Stress Scale (PSS) and hair cortisol concentrations (HCC). We identified two FI trajectories: persistent moderate FI and persistent mild FI. Moderate FI (vs. mild) was associated with higher PSS; this association was stronger among HIV-negative women. We observed a trend towards higher HCC associated with moderate FI, which did not differ by HIV status. HCC and PSS were not correlated. In summary, moderate FI (vs. mild) was associated with increased stress. The lack of PSS-HCC correlation could reflect different physiological pathways. Interventions to mitigate FI could alleviate postpartum stress.

"When I Eat Well, I Will Be Healthy, and the Child Will Also Be Healthy": Maternal Nutrition among HIV-Infected Women Enrolled in a Livelihood Intervention in Western Kenya

BACKGROUND

Food insecurity remains a major obstacle to achieving health and well-being for individuals living with HIV in western Kenya. Studies have shown that pregnant women are vulnerable to experiencing food insecurity worldwide, with significant consequences for both maternal and child health. The Shamba Maisha cluster randomized controlled trial in western Kenya (which means "farming for life" in Swahili) tested the effects of a multisectoral livelihood intervention consisting of agricultural and finance trainings, farm inputs, and a loan on health and food security among 746 farmers living with HIV in Kisumu, Homa Bay, and Migori Counties.

OBJECTIVES

We conducted a qualitative substudy within the Shamba Maisha trial to understand the experiences and perspectives of pregnant women living with HIV enrolled in the trial.

METHODS

Thirty women who had experienced a pregnancy during the Shamba Maisha study period, comprising 20 women in the intervention arm and 10 women in the control arm, completed in-depth interviews using a semistructured interview guide.

RESULTS

Intervention participants interviewed noted improvements in maternal nutrition compared with previous pregnancies, which they attributed to the livelihood intervention. Key identified pathways to improved nutrition included improved access to vegetables, increased variety of diet through vegetable sales, and improved nutritional awareness. Women in the intervention arm also perceived increased weight gain compared with prior pregnancies and increased strength and energy throughout pregnancy.

CONCLUSIONS

Livelihood interventions represent a promising solution to alleviate food insecurity for pregnant women in order to improve maternal and child health outcomes.This trial was registered at clinicaltrials.gov as NCT02815579.

Food insecurity among women of reproductive age in Nepal: prevalence and correlates

BACKGROUND

Food insecurity is widely prevalent in certain sections of society in low and middle-income countries. The United Nations has challenged all member countries to eliminate hunger for all people by 2030. This study examines the prevalence and correlates of household food insecurity among women, especially Dalit women of reproductive age in Nepal.

METHODS

Data came from 2016 Nepal Demographic Health Survey, a cross-sectional, nationally representative survey that included 12,862 women between 15 and 49 years of age of which 12% were Dalit. Descriptive analysis was used to assess the prevalence of household food insecurity while logistic regression examined the relationship between women's ethnicity and the risk of food insecurity after accounting for demographic, economic, cultural, and geo-ecological characteristics.

RESULTS

About 56% of all women and 76% of Dalit women had experienced food insecurity. Ethnicity is strongly related to food insecurity. Dalit women were most likely to be food insecure, even after accounting for factors such as education and wealth. They were 82, 85, 89 and 92% more vulnerable to food insecurity than Muslims, Brahmin/Chhetri, Terai Indigenous, and Hill Indigenous populations, respectively. Education was a protective factor-women with secondary education (6th to 10th grade) were 39% less likely to be food insecure compared to their counterparts without education. With a more than 10th grade education, women were 2.27 times more likely to be food secure compared to their counterparts without education. Marriage was also protective. Economically, household wealth is inversely correlated with food insecurity. Finally, residence in the Mid-Western, Far-Western and Central Development regions was correlated with food insecurity.

CONCLUSION

To reduce food insecurity in Nepal, interventions should focus on improving women's education and wealth, especially among Dalit and those residing in the Far- and Mid-Western regions.

Factors associated with birth preparedness and complication readiness in Southern Ethiopia: a community based cross-sectional study

Background

Birth preparedness and complication readiness (BP/CR) is a strategy to promote use of skilled maternal and neonatal care so that they can get timely skilled care, particularly during child birth. There is minimal evidence on the factors associated with BP/CR among pregnant women in Ethiopia. Hence, this study aimed to assess the factors influencing BP/CR among pregnant women in Southern Ethiopia for the purpose of improving utilization of skilled attendant at birth.

Methods

A community based cross-sectional study was conducted among 707 pregnant women in Southern Ethiopia in March 2015. Both quantitative and qualitative methods of data collection were used. For the quantitative study, the study subjects were included in the study by employing multi-stage sampling. Data was entered into Epidata version 3.1 and analyzed using IBM SPSS statistics 20. Level of statistical significance was declared at a p- value of <0.05. For the qualitative study, six FGDs were conducted and analyzed based on the thematic areas.

Result

The prevalence of BP /CR in Arba Minch Zuria Woreda was found to be 30%. The odds of being prepared for birth and its complications was higher among women from high economic class (AOR = 2.29, 95% CI = 1.16, 4.54), with frequency of antenatal care(ANC) > = 4 (AOR = 4.52, 95% CI = 2.26, 9.02), who received advice on BP &CR (AOR = 1.84, 95% CI = 1.13, 3.01),and who were knowledgeable on labor and delivery(LAD) danger signs (AOR = 1.85, 95% CI = 1.01, 3.44). However, it was lower among women with parity of 2 - 4(AOR = .0.51, 95% CI = 0.31, 0.84) and >4 (AOR = 0.51, 95% CI = 0.31, 0.84) than primiparous women. It was also lower among women from food insecure households (AOR = 0.26, 95% CI = 0.16, 0.42) than their counterparts. Lack of awareness on BP/CR, privacy and respect in health institutions were mentioned by the FGD discussants as barriers to women’s preparation for birth.

Conclusions

The study showed that BP/CR is inadequate among pregnant women in the study area. Improving socio-economic and food security status of women, strengthening community-based education on complete attendance of ANC, and conforming to professional ethical standards were recommended.

Factors associated with retention in Option B+ in Malawi: a case control study

Introduction: There are limited data on factors associated with retention in Option B+. We sought to explore the characteristics of women retained in Option B+ in Malawi, with a focus on the role of HIV disclosure, awareness of partner HIV status, and knowledge around the importance of Option B+ for maternal–child health.

Methods: We performed a case-control study of HIV-infected women in Malawi initiated on antiretroviral therapy (ART) under Option B+. Cases were enrolled if they met criteria for default from Option B+ (out of ART for >60 days), and controls were enrolled in approximately 3:1 ratio if they were retained in care for at least 12 months. We surveyed socio-demographic characteristics, HIV disclosure and awareness of partner HIV status, self-report about receiving pre-ART education, and knowledge of Option B+. Univariate logistic regression was performed to determine factors associated with retention. Multivariate logistic regression model was used to evaluate the relationship between HIV disclosure, Option B+ knowledge, and retention after adjusting for age, schooling, and travel time to clinic.

Results: We enrolled 50 cases and 153 controls. Median age was 30 years (interquartile range (IQR) 25–34), and the majority (82%) initiated ART during pregnancy at a median gestational age of 24 weeks (IQR 16–28). Ninety-one per cent of the cases (39/43) who started ART during pregnancy defaulted by three months postpartum. HIV disclosure to the primary sex partner was more common among women retained in care (100% versus 78%, p < 0.001). Odds of retention were significantly higher among women with: age >25 years (odds ratio (OR) 2.44), completion of primary school (OR 3.06), awareness of partner HIV status (OR 5.20), pre-ART education (OR 6.17), higher number of correct answers to Option B+ knowledge questions (OR 1.82), and support while taking ART (OR 3.65). Pre-ART education and knowledge were significantly correlated (r = 0.43, p < 0.001). In multivariate analysis, awareness of partner HIV status (OR 4.07, 95% confidence interval (CI) 1.51–10.94, p = 0.02) and Option B+ knowledge (OR 1.60, 95% CI 1.15–2.23, p = 0.004) remained associated with retention.

Conclusions: Interventions that address partner disclosure and strengthen pre-ART education around the benefits of ART for maternal and child health should be evaluated to improve retention in Malawi’s Option B+ programme.

What influences feeding decisions for HIV-exposed infants in rural Kenya?

BACKGROUND

Infant feeding in the context of human immunodeficiency virus (HIV) poses unique challenges to mothers and healthcare workers in balancing the perceived risks of HIV transmission and nutritional requirements. We aimed to describe the decision-making processes around infant feeding at a rural HIV clinic in Kenya.

METHODS

We used a qualitative study design. Between March and August 2011, we conducted in-depth interviews (n = 9) and focus group discussions (n = 10) with purposively selected hospital and community respondents at Kilifi County Hospital, Kenya. These respondents had all experienced of infant feeding in the context of HIV. These interviews were informed by prior structured observations of health care worker interactions with carers during infant feeding counselling sessions.

RESULTS

Overall, women living with HIV found it difficult to adhere to the HIV infant feeding guidance. There were three dominant factors that influenced decision making processes: 1) Exclusive breastfeeding was not the cultural norm, therefore practising it raised questions within the family and community about a mother's parenting capabilities and HIV status. 2) Women living with HIV lacked autonomy in decision-making on infant feeding due to socio-cultural factors. 3) Non-disclosure of HIV status to close members due to the stigma.

CONCLUSION

Infant feeding decision-making by women living with HIV in rural Kenya is constrained by a lack of autonomy, stigma and poverty. There is an urgent need to address these challenges through scaling up psycho-social and gender empowerment strategies for women, and introducing initiatives that promote the integration of HIV infant feeding strategies into other child health services.

The dimensions of food insecurity and malnutrition among people living with HIV in Senegal, West Africa

An understanding of the factors contributing to food insecurity and malnutrition among people living with HIV (PLHIV) in Senegal is urgently needed in order to develop effective interventions. The goals of this study were to identify differences in the dimensions of food security among PLHIV in Dakar versus Ziguinchor, Senegal, to determine which of these dimensions are most predictive of severe food insecurity, and to identify factors associated with malnutrition. We conducted a cross-sectional study at outpatient clinics in Dakar and Ziguinchor, Senegal. Data were collected using participant interviews, anthropometry, the Household Food Insecurity Access Scale, the Individual Dietary Diversity Scale, and chart review. Interviews were conducted with ninety-five food insecure, HIV-infected subjects. Daily household income and daily food expenditure per household member were the strongest predictors of severe food insecurity. The practice of agriculture, livestock ownership, nutritional status, and HIV outcomes were not predictive of severe food insecurity. CD4 count <350/mm³ was the strongest predictor of malnutrition. Severe food insecurity, daily household income, daily food expenditure per household member, dietary diversity score, skipping meals, the practice of agriculture, livestock ownership, ART status, and adherence were not predictive of malnutrition. This is the first study to analyze the dimensions of food security among PLHIV in Senegal. We discovered important differences in food access, availability, stability, and utilization in Dakar versus Ziguinchor. We found that economic access was the strongest predictor of severe food insecurity and poorly controlled HIV was the strongest predictor of malnutrition. Our findings suggest that the interventions needed to address food insecurity differ from those necessary to target malnutrition, and that effective interventions may differ in Dakar versus Ziguinchor. Furthermore, this study highlights a need for a greater understanding of the relationship between HIV and malnutrition among individuals receiving ART in resource-limited settings.

Food insecurity, sexual risk behavior, and adherence to antiretroviral therapy among women living with HIV: A systematic review

Gender inequalities shape the experience of food insecurity among women living with HIV (WLHIV). We systematically reviewed the impact of food insecurity on sexual risk behaviors and antiretroviral therapy (ART) adherence among WLHIV. We included qualitative or quantitative peer-reviewed articles, extracted data in duplicate, and assessed rigor. Seven studies, from sub-Saharan Africa, North America, and Europe, met inclusion criteria. Food insecurity was associated with increased sexual risk through transactional sex and inability to negotiate safer sex. Hunger and food insecurity were barriers to ART initiation/adherence. Multidimensional programming and policies should simultaneously address poverty, gender inequality, food insecurity, and HIV.

Brief Report: Food Insufficiency Is Associated With Lack of Sustained Viral Suppression Among HIV-Infected Pregnant and Breastfeeding Ugandan Women

Supplemental Digital Content is Available in the Text.

Food insecurity is associated with poor virologic outcomes, but this has not been studied during pregnancy and breastfeeding. We assessed sustained viral suppression from 8 weeks on antiretroviral therapy to 48 weeks postpartum among 171 pregnant and breastfeeding Ugandan women; 74.9% experienced food insufficiency. In multivariable analysis, food insufficiency [adjusted odds ratio (aOR) 0.38, 95% confidence interval (CI): 0.16 to 0.91], higher pretreatment HIV-1 RNA (aOR 0.55 per 10-fold increase, 95% CI: 0.37 to 0.82), and lopinavir/ritonavir versus efavirenz (aOR 0.49, 95% CI: 0.24 to 0.96) were associated with lower odds of sustained viral suppression. Interventions to address food security may improve virologic outcomes among HIV-infected women.

HIV-1 Vertical Transmission in Zimbabwe in 622 Mother and Infant Pairs: Rethinking the Contribution of Mannose Binding Lectin Deficiency in Africa

Vertical transmission of human immunodeficiency virus (HIV) remains a major global health problem. We assessed the association of mannose binding lectin (MBL) deficiency and vertical transmission of HIV. Novel diagnostics would be a major breakthrough in this regard. MBL is a liver-derived protein and a key component of the innate immune system. MBL levels may be classified as normal, intermediate, or deficient in the plasma and can use MBL2 haplotypes as a proxy. These haplotypes comprise polymorphisms in the MBL2 gene and promoter region and are known to result in varying levels of MBL deficiency. MBL deficiency can be defined as presence of A/O and O/O genotypes in the mothers and their children. MBL deficiency leads to defective opsonization activities of the innate immune system and increased susceptibility to several infections, including HIV-1. We determined the prevalence of MBL deficiency, using MBL2 haplotypes among 622 HIV-positive Zimbabwean mothers and their children aged 9-18 months old, in relation to the HIV-1 vertical transmission risk. The median age of the mothers was 30 (26-34, interquartile range [IQR]) years, and the babies' median age was 13 (11-15, IQR) months old at the time of enrollment. From the sample of 622 mothers who were HIV-1 infected, 574 babies were HIV negative and 48 were HIV-1-positive babies, giving a transmission rate of 7.7%. MBL2 normal structural allele A and variants B (codon 5 A>G), C (codon 57 A>G), and promoter region SNPs -550(H/L) and -221(X/Y) were detected. Prevalence of haplotype-predicted MBL deficiency was 34% among the mothers and 32% among the children. We found no association between maternal MBL2 deficiency and HIV-1 transmission to their children. We found no difference in the distribution of HIV-1 infected and uninfected children between the MBL2 genotypes of the mothers and those of the children. Taken together, the present study in a large sample of mother-infant pairs in Zimbabwe adds to the emerging literature and the hypothesis that MBL2 variation as predicted by haplotypes does not influence the vertical transmission risk for HIV. Research from other populations from the African continent is called for to test this hypothesis further.

Addressing gender inequalities to improve the sexual and reproductive health and wellbeing of women living with HIV

INTRODUCTION

Globally, women constitute 50% of all persons living with HIV. Gender inequalities are a key driver of women's vulnerabilities to HIV. This paper looks at how these structural factors shape specific behaviours and outcomes related to the sexual and reproductive health of women living with HIV.

DISCUSSION

There are several pathways by which gender inequalities shape the sexual and reproductive health and wellbeing of women living with HIV. First, gender norms that privilege men's control over women and violence against women inhibit women's ability to practice safer sex, make reproductive decisions based on their own fertility preferences and disclose their HIV status. Second, women's lack of property and inheritance rights and limited access to formal employment makes them disproportionately vulnerable to food insecurity and its consequences. This includes compromising their adherence to antiretroviral therapy and increasing their vulnerability to transactional sex. Third, with respect to stigma and discrimination, women are more likely to be blamed for bringing HIV into the family, as they are often tested before men. In several settings, healthcare providers violate the reproductive rights of women living with HIV in relation to family planning and in denying them care. Lastly, a number of countries have laws that criminalize HIV transmission, which specifically impact women living with HIV who may be reluctant to disclose because of fears of violence and other negative consequences.

CONCLUSIONS

Addressing gender inequalities is central to improving the sexual and reproductive health outcomes and more broadly the wellbeing of women living with HIV. Programmes that go beyond a narrow biomedical/clinical approach and address the social and structural context of women's lives can also maximize the benefits of HIV prevention, treatment, care and support.
