RESUMO

INTRODUCTION: Reliable and timely laboratory results are crucial for monitoring the Prevention of the Mother-to-Child Transmission (PMTCT) cascade, particularly to enable early HIV diagnosis and early intervention. We sought to explore whether and how laboratory services have been prepared to absorb new testing requirements following PMTCT Test-and-Treat policy changes in three districts of Zambia. METHOD: We employed in-depth interviews and thematic data analysis, informed by the health system dynamic framework. Twenty-Six health workers were purposively selected and a document review of laboratory services in the context of PMTCT was undertaken. All face-to-face interviews were conducted in three local government areas in the Copperbelt Province (one urban and two rural) between February 2019 and July 2020. We extracted notes and markings from the transcripts for coding. Different codes were sorted into potential themes and the data extracted were put within the identified themes. Trustworthiness was confirmed by keeping records of all data field notes, transcripts, and reflexive journals. RESULTS: The findings revealed that the health system inputs (infrastructure and supplies, human resources, knowledge, and information and finance) and service delivery were unequal between the rural and urban sites, and this affected the ability of health facilities to apply the new testing requirements, especially, in the rural-based health facilities. The major barriers identified include gaps in the capacity of the existing laboratory system to perform crucial PMTCT clinical and surveillance functions in a coordinated manner and insufficient skilled human resources to absorb the increased testing demands. The centralized laboratory system for HIV testing of mothers and exposed neonates meant facilities had to send specimens to other facilities and districts which resulted in high turnaround time and hence delayed HIV diagnosis. CONCLUSION: New guidelines implemented without sufficient capacitation of health system laboratory capacity severely limited the effectiveness of PMTCT program implementation. This study documented the areas relating to health system inputs and laboratory service delivery where greater support to enable the absorption of the new testing requirements is needed.

RESUMO

BACKGROUND: Many women work in positions of non-standard employment, with limited legal and social protection. Access to comprehensive maternity protection for all working women could ensure that all women and children can access health and social protection. This study aimed to describe the maternity protection benefits available to women in positions of non-standard employment in South Africa, using domestic workers as a case study. METHODS: A qualitative descriptive study design was used. National policy documents containing provisions on maternity protection were identified and analysed. Interviews were conducted with purposively selected key informants. Data extracted from published policy documents and information obtained from interviews were triangulated. A thematic analysis approach was used for evaluation of policy content and analysis of the interviews. RESULTS: Twenty-nine policy and legislative documents were identified that contain provisions on maternity protection relevant to non-standard workers. These documents together with three key informant interviews and two media releases are used to describe availability and accessibility of maternity protection benefits for non-standard workers in South Africa, using domestic workers as a case study. Maternity protection is available in South Africa for some non-standard workers. However, the components of maternity protection are dispersed through many policy documents and there is weak alignment within government on maternity protection. Implementation, monitoring, and enforcement of existing maternity protection policy is inadequate. It is difficult for non-standard workers to access maternity protection benefits, particularly cash payments. Some non-standard workers have unique challenges in accessing maternity protection, for example domestic workers whose place of work is a private household and therefore difficult to monitor. CONCLUSION: The heterogeneity of non-standard employment makes it challenging for many women to access maternity protection. There are policy amendments that could be made and improvements to policy implementation that would enhance non-standard workers' access to maternity protection. Potential long-term benefits to women and children's health and development could come from making comprehensive maternity protection available and accessible to all women.

RESUMO

BACKGROUND: Despite strong evidence showing the lifelong benefits of breastfeeding for mothers and children, global breastfeeding practices remain poor. The International Code of Marketing of Breastmilk Substitutes is an internationally agreed code of practice, adopted by the World Health Assembly in 1981, to regulate promotion of commercial formula, and is supported by legislation in many countries. However, marketing of formula remains widespread and contributes to mother's decisions to formula feed. We present South African data from a multi-country, mixed-methods study exploring women's decision-making about infant feeding and how this was influenced by exposure to formula marketing. METHODS: Using a consumer-based marketing approach, focus group discussions (FGDs) were conducted with pregnant women and mothers of children aged between 0 and 18 months in two urban sites in South Africa. Participants were purposively selected according to their child's age, infant feeding practices and socioeconomic status. Ten FGDs were conducted during February 2020 with a total of 69 participants. Thematic analysis was used to analyse the data with NVivo v.12 software. RESULTS: Despite being encouraged by health professionals to breastfeed and intending to do so, many mothers chose to give formula in the early weeks and months of their child's life. Mothers reported breastfeeding challenges as the most frequent reason for initiating infant formula, stating that family members and health professionals recommended formula to solve these challenges. Although participants described few advertisements for infant formula, advertisements for 'growing-up' formulas for older children were widespread and promoted brand recognition. Mothers experienced other marketing approaches including attractive packaging and shop displays of infant formula, and obtained information from social media and online mothers' groups, which influenced their choice of formula brand. Mothers reported strong brand loyalty derived from previous experiences and recommendations. Health professionals frequently recommended formula, including recommending specific formula brands and specialist formulas. CONCLUSION: Global formula companies use multifaceted marketing methods to promote a strong narrative portraying formula feeding as a positive lifestyle choice. Positive, coordinated efforts are required to counter pro-formula messaging and change the narrative to support breastfeeding as an aspirational choice. In particular, health professionals must stop supporting the formula industry.

RESUMO

BACKGROUND: The leading causes of mortality globally in children younger than five years of age (under-fives), and particularly in the regions of sub-Saharan Africa (SSA) and Southern Asia, in 2018 were infectious diseases, including pneumonia (15%), diarrhoea (8%), malaria (5%) and newborn sepsis (7%) (UNICEF 2019). Nutrition-related factors contributed to 45% of under-five deaths (UNICEF 2019). World Health Organization (WHO) and United Nations Children's Fund (UNICEF), in collaboration with other development partners, have developed an approach - now known as integrated community case management (iCCM) - to bring treatment services for children 'closer to home'. The iCCM approach provides integrated case management services for two or more illnesses - including diarrhoea, pneumonia, malaria, severe acute malnutrition or neonatal sepsis - among under-fives at community level (i.e. outside of healthcare facilities) by lay health workers where there is limited access to health facility-based case management services (WHO/UNICEF 2012). OBJECTIVES: To assess the effects of the integrated community case management (iCCM) strategy on coverage of appropriate treatment for childhood illness by an appropriate provider, quality of care, case load or severity of illness at health facilities, mortality, adverse events and coverage of careseeking for children younger than five years of age in low- and middle-income countries. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase and CINAHL on 7 November 2019, Virtual Health Library on 8 November 2019, and Popline on 5 December 2018, three other databases on 22 March 2019 and two trial registers on 8 November 2019. We performed reference checking, and citation searching, and contacted study authors to identify additional studies. SELECTION CRITERIA: Randomized controlled trials (RCTs), cluster-RCTs, controlled before-after studies (CBAs), interrupted time series (ITS) studies and repeated measures studies comparing generic WHO/UNICEF iCCM (or local adaptation thereof) for at least two iCCM diseases with usual facility services (facility treatment services) with or without single disease community case management (CCM). We included studies reporting on coverage of appropriate treatment for childhood illness by an appropriate provider, quality of care, case load or severity of illness at health facilities, mortality, adverse events and coverage of careseeking for under-fives in low- and middle-income countries. DATA COLLECTION AND ANALYSIS: At least two review authors independently screened abstracts, screened full texts and extracted data using a standardised data collection form adapted from the EPOC Good Practice Data Collection Form. We resolved any disagreements through discussion or, if required, we consulted a third review author not involved in the original screening. We contacted study authors for clarification or additional details when necessary. We reported risk ratios (RR) for dichotomous outcomes and hazard ratios (HR) for time to event outcomes, with 95% confidence intervals (CI), adjusted for clustering, where possible. We used estimates of effect from the primary analysis reported by the investigators, where possible. We analysed the effects of randomized trials and other study types separately. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS: We included seven studies, of which three were cluster RCTs and four were CBAs. Six of the seven studies were in SSA and one study was in Southern Asia. The iCCM components and inputs were fairly consistent across the seven studies with notable variation for the training and deployment component (e.g. on payment of iCCM providers) and the system component (e.g. on improving information systems). When compared to usual facility services, we are uncertain of the effect of iCCM on coverage of appropriate treatment from an appropriate provider for any iCCM illness (RR 0.96, 95% CI 0.77 to 1.19; 2 CBA studies, 5898 children; very low-certainty evidence). iCCM may have little to no effect on neonatal mortality (HR 1.01, 95% 0.73 to 1.28; 2 trials, 65,209 children; low-certainty evidence). We are uncertain of the effect of iCCM on infant mortality (HR 1.02, 95% CI 0.83 to 1.26; 2 trials, 60,480 children; very low-certainty evidence) and under-five mortality (HR 1.18, 95% CI 1.01 to 1.37; 1 trial, 4729 children; very low-certainty evidence). iCCM probably increases coverage of careseeking to an appropriate provider for any iCCM illness by 68% (RR 1.68, 95% CI 1.24 to 2.27; 2 trials, 9853 children; moderate-certainty evidence). None of the studies reported quality of care, severity of illness or adverse events for this comparison. When compared to usual facility services plus CCM for malaria, we are uncertain of the effect of iCCM on coverage of appropriate treatment from an appropriate provider for any iCCM illness (very low-certainty evidence) and iCCM may have little or no effect on careseeking to an appropriate provider for any iCCM illness (RR 1.06, 95% CI 0.97 to 1.17; 1 trial, 811 children; low-certainty evidence). None of the studies reported quality of care, case load or severity of illness at health facilities, mortality or adverse events for this comparison. AUTHORS' CONCLUSIONS: iCCM probably increases coverage of careseeking to an appropriate provider for any iCCM illness. However, the evidence presented here underscores the importance of moving beyond training and deployment to valuing iCCM providers, strengthening health systems and engaging community systems.

RESUMO

BACKGROUND: While HIV Testing Services (HTS) have increased, many South Africans have not been tested. Non-communicable diseases (NCDs) are the top cause of death worldwide. Integrated NCD-HTS could be a strategy to control both epidemics. Healthcare service strategies depends partially on positive user experience. We investigated client satisfaction of services and clinic flow time of an integrated NCD-HTS clinic. METHODS: This prospective, cross-sectional study evaluated HTS client satisfaction with an HTS clinic at two phases. Phase 1 (February-June 2018) utilised standard HTS services: counsellor-led height/weight/blood pressure measurements, HIV rapid testing, and symptoms screening for sexually transmitted infections/Tuberculosis. Phase 2 (June 2018-March 2019) further integrated counsellor-led obesity screening (body mass index/abdominal circumference measurements), rapid cholesterol/glucose testing; and nurse-led Chlamydia and human papilloma virus (HPV)/cervical cancer screening. Socio-demographics, proportion of repeat clients, clinic flow time, and client survey data (open/closed-ended questions using five-point Likert scale) are reported. Fisher's exact test, chi-square analysis, and Kruskal Wallis test conducted comparisons. Multiple linear regression determined predictors associated with clinic time. Content thematic analysis was conducted for free response data. RESULTS: Two hundred eighty-four and three hundred thirty-three participants were from Phase 1 and 2, respectively (N = 617). Phase 1 participants were significantly older (median age 36.5 (28.0-43.0) years vs. 31.0 (25.0-40.0) years; p = 0.0003), divorced/widowed (6.7%, [n = 19/282] vs. 2.4%, [n = 8/332]; p = 0.0091); had tertiary education (27.9%, [n = 79/283] vs. 20.1%, [n = 67/333]; p = 0.0234); and less female (53.9%, [n = 153/284] vs 67.6%, [n = 225/333]; p = 0.0005), compared to Phase 2. Phase 2 had 10.2% repeat clients (n = 34/333), and 97.9% (n = 320/327) were 'very satisfied' with integrated NCD-HTS, despite standard HTS having significantly shorter median time for counsellor-led HTS (36.5, interquartile range [IQR]: 31.0-45.0 vs. 41.5, IQR: 35.0-51.0; p < 0.0001). Phase 2 associations with longer clinic time were clients living together/married (est = 6.548; p = 0.0467), more tests conducted (est = 3.922; p < 0.0001), higher overall satisfaction score (est = 1.210; p = 0.0201). Those who matriculated experienced less clinic time (est = - 7.250; p = 0.0253). CONCLUSIONS: It is possible to integrate counsellor-led NCD rapid testing into standard HTS within historical HTS timeframes, yielding client satisfaction. Rapid cholesterol/glucose testing should be integrated into standard HTS. Research is required on the impact of cervical cancer/HPV screenings to HTS clinic flow to determine if it could be scaled up within the public sector.

RESUMO

Breastfeeding education and support are critical health worker skills. Confusion surrounding infant feeding advice linked to the HIV epidemic has reduced the confidence of health workers to support breastfeeding. High antiretroviral therapy coverage of breastfeeding women living with HIV, and an Infant Feeding policy supportive of breastfeeding, now provides an opportunity to improve breastfeeding practices. Challenges remain in restoring health worker confidence to support breastfeeding. This qualitative study presents findings from focus group discussions with mothers of young infants, exploring their experiences of health worker breastfeeding counselling and support. Analysis followed the thematic framework approach. Six researchers reviewed the transcripts, coded them independently, then jointly reviewed the codes, and agreed on a working analytical framework. Although mothers received antenatal breastfeeding messages, these appeared to focus rigidly on the importance of exclusivity. Mothers described receiving some practical support with initiation of breastfeeding after delivery, but support and advice for post-natal breastfeeding challenges were often incorrect or absent. The support also ignored the context in which women make infant feeding decisions, including returning to work and pressures from family members. Despite improved breastfeeding policies, restoring confidence in health workers to support breastfeeding remains a challenge. The post-natal period, when mothers experience breastfeeding difficulties, is particularly critical, and our findings reinforce the importance of continuity of care between communities and health facilities. This research has implications for how health workers are trained to support breastfeeding. Greater attention is needed on developing skills and confidence in identifying, assessing, and supporting women experiencing breastfeeding challenges.

RESUMO

Clinical guidelines are used to translate research findings into evidence-based clinical practice but are frequently not comprehensively adopted by health workers (HWs). HIV and infant feeding guidelines were revised by the World Health Organization to align feeding advice for HIV-exposed and unexposed infants, and these were adopted in South Africa in 2017. We describe an innovative, team-based, mentoring programme developed to update HWs on these guidelines. The intervention was underpinned by strong theoretical frameworks and aimed to improve HWs' attitudes, knowledge, confidence, and skills about breastfeeding in the context of HIV. On-site workshops and clinical mentoring used interactive participatory methods and a simple low-tech approach, guided by participants' self-reported knowledge gaps. Workshops were conducted at 24 participating clinics over three sessions, each lasting 1-2 hr. Evaluation data were collected using a self-administered questionnaire. Of 303 participating HWs, 249/303 (82.2%) attended all workshops. Achieving high workshop attendance was challenging and "catch-up" sessions were required to achieve good coverage. Common knowledge gaps identified included antiretroviral therapy adherence monitoring during breastfeeding and management of viral load results (173 participants), management of breast conditions (79), and advice about expressing and storing breastmilk (64). Most participants reported all their knowledge gaps were addressed and anticipated that their practice would change. We describe a feasible, sustainable approach to updating HWs on HIV and infant feeding guidelines and improving skills in breastfeeding counselling in resource-constrained settings. This approach could be adapted to other topics and, with further evaluation, implemented at scale using existing resources.

RESUMO

In the last 15 years, antiretroviral therapy (ART) has been the most globally impactful life-saving development of medical research. Antiretrovirals (ARVs) are used with great success for both the treatment and prevention of HIV infection. Despite these remarkable advances, this epidemic grows relentlessly worldwide. Over 2.1 million new infections occur each year, two-thirds in women and 240,000 in children. The widespread elimination of HIV will require the development of new, more potent prevention tools. Such efforts are imperative on a global scale. However, it must also be recognised that true containment of the epidemic requires the development and widespread implementation of a scientific advancement that has eluded us to date--a highly effective vaccine. Striving for such medical advances is what is required to achieve the end of AIDS.

RESUMO

Background: Human immunodeficiency virus (HIV)-infected pregnant women increasingly receive antiretroviral therapy (ART) to prevent mother-to-child transmission (PMTCT). Studies suggest HIV-exposed uninfected (HEU) children face higher mortality than HIV-unexposed children, but most evidence relates to the pre-ART era, breastfeeding of limited duration, and considerable maternal mortality. Maternal ART and prolonged breastfeeding while on ART may improve survival, although this has not been reliably quantified. Methods: Individual data on 19 219 HEU children from 21 PMTCT trials/cohorts undertaken from 1995 to 2015 in Africa and Asia were pooled to estimate the association between 24-month mortality and maternal/infant factors, using random-effects Cox proportional hazards models. Adjusted attributable fractions of risks computed using the predict function in the R package "frailtypack" were used to estimate the relative contribution of risk factors to overall mortality. Results: Cumulative incidence of death was 5.5% (95% confidence interval, 5.1-5.9) by age 24 months. Low birth weight (LBW <2500 g, adjusted hazard ratio (aHR, 2.9), no breastfeeding (aHR, 2.5), and maternal death (aHR, 11.1) were significantly associated with increased mortality. Maternal ART (aHR, 0.5) was significantly associated with lower mortality. At the population level, LBW accounted for 16.2% of 24-month mortality, never breastfeeding for 10.8%, mother not receiving ART for 45.6%, and maternal death for 4.3%; combined, these factors explained 63.6% of deaths by age 24 months. Conclusions: Survival of HEU children could be substantially improved if public health practices provided all HIV-infected mothers with ART and supported optimal infant feeding and care for LBW neonates.

RESUMO

To maximize the benefits of test and treat strategies that utilize community-based HIV testing, clients who test positive must link to care in a timely manner. However, linkage rates across the HIV treatment cascade are typically low and little is known about what might facilitate or hinder care-seeking behavior. This qualitative study was conducted within a home-based HIV counseling and testing (HBHCT) intervention in South Africa. In-depth interviews were conducted with 30 HBHCT clients who tested HIV positive to explore what influenced their care-seeking behavior. A set of field notes for 196 additional HBHCT clients who tested HIV positive at home were also reviewed and analyzed. Content analysis showed that linkage to care is influenced by a myriad of factors at the individual, relationship, community, and health system levels. These factors subtly interact and at times reinforce each other. While some factors such as belief in test results, coping ability, social support, and prior experiences with the health system affect clients' desire and motivation to seek care, others such as limited time and resources affect their agency to do so. To ensure that the benefits of community-based testing models are realized through timely linkage to care, programs and interventions must take into account and address clients' emotions, motivation levels, living situations, relationship dynamics, responsibilities, and personal resources.

RESUMO

Since there is no doubt concerning the superiority of breastfeeding compared to other forms of infant feeding, the promotion of exclusive breastfeeding up to six months and continued breastfeeding up to two years and beyond are again embraced at the highest global nutrition agenda. The latest is the United Nations decade of action on nutrition 2016-2025, building on research results and the work by the World Health Organization (WHO) over the last two decades, and extensive societal, clinical, and academic discussions in the field of breastfeeding.While the discussion was about the optimal duration of exclusive breastfeeding around the millennium shift, the focus is on the most effective measures for the promotion and protection of breastfeeding. Contemporary breastfeeding rates are well behind the goals. In sub-Saharan Africa, almost all infants are breastfed, while exclusive breastfeeding is more seldom and not sufficient. Africa, being a vast and diverse continent with a myriad of cultural practices, has had some shared attitudes ranging from the west to east regarding views on motherhood, body fluids, including milk, infant feeding, and responsible others.The region still faces high maternal HIV infection rates and high infant and child mortality rates. However, due to effective antiretroviral therapies, it is now possible and safe for women living with HIV to breastfeed their infants and to ensure them HIV-free survival. However, there is need for improvement regarding availability, compliance, and adherence to these drugs. Research gaps include the long-term effects of antiretroviral therapy on the growth, health, and development of the exposed children.

RESUMO

BACKGROUND: In October 2012 Uganda extended its prevention of mother to child HIV transmission (PMTCT) policy to Option B+, providing lifelong antiretroviral treatment for HIV positive pregnant and breastfeeding women. The rapid changes and adoptions of new PMTCT policies have not been accompanied by health systems research to explore health system preparedness to implement such programmes. The implementation of Option B+ provides many lessons which can inform the shift to 'Universal Test and Treat', a policy which many sub-Saharan African countries are preparing to adopt, despite fragile health systems. METHODS: This qualitative study of PMTCT Option B+ implementation in Uganda three years following the policy adoption, uses the health system dynamics framework to explore the impacts of this programme on ten elements of the health system. Qualitative data were gathered through rapid appraisal during in-country field work. Key informant interviews and focus group discussions (FGDs) were undertaken with the Ministry of Health, implementing partners, multilateral agencies, district management teams, facility-based health workers and community cadres. A total of 82 individual interviews and 16 focus group discussions were completed. We conducted a simple manifest analysis, using the ten elements of a health system for grouping data into categories and themes. RESULTS: Of the ten elements in the health system dynamics framework, context and resources (finances, infrastructure & supplies, and human resources) were the most influential in the implementation of Option B+ in Uganda. Support from international actors and implementing partners attempted to strengthen resources at district level, but had unintended consequences of creating dependence and uncertainty regarding sustainability. CONCLUSIONS: The health system dynamics framework offers a novel approach to analysis of the effects of implementation of a new policy on critical elements of the health system. Its emphasis on relationships between system elements, population and context is helpful in unpacking impacts of and reactions to pressures on the system, which adds value beyond some previous frameworks.

RESUMO

OBJECTIVE: Cash transfer programmes targeting children are considered an effective strategy for addressing child poverty and for improving child health outcomes in developing countries. In South Africa, the Child Support Grant (CSG) is the largest cash transfer programme targeting children from poor households. The present paper investigates the association of the duration of CSG receipt with child growth at 2 years in three diverse areas of South Africa. DESIGN: The study analysed data on CSG receipt and anthropometric measurements from children. Predictors of stunting were assessed using a backward regression model. SETTING: Paarl (peri-urban), Rietvlei (rural) and Umlazi (urban township), South Africa, 2008. SUBJECTS: Children (n 746), median age 22 months. RESULTS: High rates of stunting were observed in Umlazi (28 %), Rietvlei (20 %) and Paarl (17 %). Duration of CSG receipt had no effect on stunting. HIV exposure (adjusted OR=2·30; 95 % CI 1·31, 4·03) and low birth weight (adjusted=OR 2·01, 95 % CI 1·02, 3·96) were associated with stunting, and maternal education had a protective effect on stunting. CONCLUSIONS: Our findings suggest that, despite the presence of the CSG, high rates of stunting among poor children continue unabated in South Africa. We argue that the effect of the CSG on nutritional status may have been eroded by food price inflation and limited progress in the provision of other important interventions and social services.

RESUMO

Hypertensive disorders of pregnancy (HDP), particularly pre-eclampsia and eclampsia, remain one of the leading causes of maternal mortality and are contributory in many foetal/newborn deaths. This editorial discusses a supplement of seven papers which provide the results of the first round of the CLIP (Community Level Interventions for Pre-eclampsia) Feasibility Studies. These studies report a number of enablers and barriers in each setting, which have informed the implementation of a cluster-randomized trial (cRCT) aimed at reducing pre-eclampsia-related, and all-cause, maternal and perinatal mortality and major morbidity using community-based identification and treatment of pre-eclampsia in selected geographies of Nigeria, Mozambique, Pakistan and India. This supplement unpacks the diverse community perspectives on determinants of maternal health, variant health worker knowledge and routine management of HDP, and viability of task sharing for preeclampsia identification and management in select settings. These studies demonstrate the need for strategies to improve health worker knowledge and routine management of HDP and consideration of expanding the role of community health workers to reach the most remote women and families with health education and access to health services.

RESUMO

OBJECTIVE: To analyse the effect of community-based counselling on feeding patterns during the first 12 weeks after birth, and to study whether the effect differs by maternal HIV status, educational level or household wealth. DESIGN: Cluster-randomized trial with fifteen clusters in each arm to evaluate an integrated package providing two pregnancy and five postnatal home visits delivered by community health workers. Infant feeding data were collected using 24 h recall of nineteen food and fluid items. SETTING: A township near Durban, South Africa. SUBJECTS: Pregnant women (1894 intervention and 2243 control) aged 17 years or more. RESULTS: Twelve weeks after birth, 1629 (intervention) and 1865 (control) mother-infant pairs were available for analysis. Socio-economic conditions differed slightly across intervention groups, which were considered in the analyses. There was no effect on early initiation of breast-feeding. At 12 weeks of age the intervention doubled exclusive breast-feeding (OR=2·29; 95 % CI 1·80, 2·92), increased exclusive formula-feeding (OR=1·70; 95 % CI 1·28, 2·27), increased predominant breast-feeding (OR=1·71; 95 % CI 1·34, 2·19), decreased mixed formula-feeding (OR=0·68; 95 % CI 0·55, 0·83) and decreased mixed breast-feeding (OR=0·54; 95 % CI 0·44, 0·67). The effect on exclusive breast-feeding at 12 weeks was stronger among HIV-negative mothers than HIV-positive mothers (P=0·01), while the effect on mixed formula-feeding was significant only among HIV-positive mothers (P=0·03). The effect on exclusive feeding was not different by household wealth or maternal education levels. CONCLUSIONS: A perinatal intervention package delivered by community health workers was effective in increasing exclusive breast-feeding, exclusive formula-feeding and decreasing mixed feeding.

RESUMO

BACKGROUND: An estimated 2.8 million neonatal deaths occur annually worldwide. The vulnerability of newborns makes the timeliness of seeking and receiving care critical for neonatal survival and prevention of long-term sequelae. To better understand the role active referrals by community health workers play in neonatal careseeking, we synthesize data on referral completion rates for neonates with danger signs predictive of mortality or major morbidity in low- and middle-income countries. METHODS: A systematic review was conducted in May 2014 of the following databases: Medline-PubMed, Embase, and WHO databases. We also searched grey literature. In addition, an investigator group was established to identify unpublished data on newborn referral and completion rates. Inquiries were made to the network of research groups supported by Save the Children's Saving Newborn Lives project and other relevant research groups. RESULTS: Three Sub-Saharan African and five South Asian studies reported data on community-to-facility referral completion rates. The studies varied on factors such as referral rates, the assessed danger signs, frequency of home visits in the neonatal period, and what was done to facilitate referrals. Neonatal referral completion rates ranged from 34 to 97 %, with the median rate of 74 %. Four studies reported data on the early neonatal period; early neonatal completion rates ranged from 46 to 97 %, with a median of 70 %. The definition of referral completion differed by studies, in aspects such as where the newborns were referred to and what was considered timely completion. CONCLUSIONS: Existing literature reports a wide range of neonatal referral completion rates in Sub-Saharan Africa and South Asia following active illness surveillance. Interpreting these referral completion rates is challenging due to the great variation in study design and context. Often, what qualifies as referral and/or referral completion is poorly defined, which makes it difficult to aggregate existing data to draw appropriate conclusions that can inform programs. Further research is necessary to continue highlighting ways for programs, governments, and policymakers to best aid families in low-resource settings in protecting their newborns from major health consequences.

RESUMO

Data from a prospective multisite cohort study were used to examine the effect of HIV exposure, untreated HIV infection, and single-dose nevirapine on infant growth velocity. The 2009 WHO growth velocity standards constitute a new tool for this type of investigation and are in need of functional validation. In period 1 (3-24 wk), 65 HIV-infected, 502 HIV-exposed uninfected (HEU), and 216 HIV-unexposed infants were included. In period 2 (25-36 wk), 31 infants moved from the HEU group to the HIV-infected group. We compared weight velocity Z-scores (WVZ) and length velocity Z-scores (LVZ) by HIV group and assessed their independent influences. In period 1, mean WVZ (95% CI) was significantly (P < 0.001) lower in infected [-0.87 (-1.77, 0.04)] than HEU [0.81 (0.67, 0.94)] and unexposed [0.55 (0.33, 0.78)] infants. LVZ showed similar associations. In both periods, sick infants and those exposed to higher maternal viral loads had lower WVZ. Higher mean LVZ was associated with low birth weight. Infants that had received nevirapine had higher LVZ. In conclusion, HIV infection and not exposure was associated with low WVZ and LVZ in period 1. Eliminating infant HIV infection is a critical component in averting HIV-related poor growth patterns in infants in the first 6 mo of life.
