Community health workers can improve child growth of antenatally-depressed, South African mothers: a cluster randomized controlled trial

Empowerment strategies of the Mentor Mother peer support program among mothers who have migrated to Sweden: a photovoice study

INTRODUCTION

A peer support intervention using 'Mentor Mothers' was implemented for mothers who had migrated to Sweden, living in socially disadvantaged communities. The Mentor Mothers had a high degree of freedom to develop strategies for facilitating empowerment of their clients according to perceived needs. This study aimed to investigate which empowerment facilitation strategies that Mentor Mothers perceived to be relevant, feasible and effective.

METHODS

Photovoice was used to generate qualitative data. Participants took photographs of their work which were then discussed during a focus group discussion and six individual semi-structured interviews. Data were analysed using thematic analysis.

RESULTS

Four overarching strategies to facilitate empowerment were identified, corresponding to distinctive perceived needs in the target group: (1) Informative support responded to a need for making sense of the external context, by helping mothers navigate society, the process of parenthood and cultural parenting norms. (2) Practical support addressed a need for managing challenges in daily life, by facilitating contacts with welfare services and authorities and to enhance parenting practices. (3) Psychosocial support addressed a need for improved mental wellbeing, by instilling feelings of safety and security in daily life, relationships and in contacts with public institutions. (4) Motivational support responded to a need for finding fulfilling purpose, by promoting social interaction, encouraging civic engagement and sharing the challenges and successes of others to inspire hope.

CONCLUSIONS

These results highlight various aspects of peer support for empowerment facilitation that future interventions targeting immigrant parents can use in their intervention design.

Community Health Workers' experiences of a package providing increased support and supervision - a qualitative study of a home visiting model in rural South Africa

Deploying Community Health Workers is a crucial strategy to improve health at a community level in low and middle income countries. While there is substantial evidence for CHW effectiveness, there is a need for more research on the mechanisms through which these programs work. Understanding CHWs experiences of how programmes function is important. This article examines CHW's experiences of three key programmatic domains; training, logistical support and supervision. Data were gathered using a qualitative study embedded within a cluster randomized controlled trial of an enhanced supervision package delivered to government-employed CHWs in the rural Eastern Cape, South Africa. We interviewed CHWs (n = 16) and two supervisors. Three overarching areas and five sub-themes emerged from our interviews. CHW knowledge and confidence increased through additional training, that CHW motivation and community acceptance improved because of added logistical support, and that CHW supervision led to improved sense of accountability, feelings of respect, and sense of being supported. Our findings highlight the importance of a functional support system within which CHWs can operate, in a context where most CHWs operate in isolation and without support. CHWs receiving supportive supervision reported positive impacts on their motivation and ability to carry out their work effectively.

Risks of adverse perinatal outcomes in relation to maternal depressive symptoms: A prospective cohort study in Kenya

BACKGROUND

Evidence gaps remain regarding the influence of prenatal psychosocial factors on adverse pregnancy outcomes.

OBJECTIVE

The objective of this study is to evaluate relationships between psychosocial factors and adverse perinatal outcomes among Kenyan women.

METHODS

We analysed data from a prospective cohort study enrolling HIV-negative women in pregnancy (NCT03070600) in 20 antenatal clinics in Western Kenya. Study nurses assessed depressive symptoms using the Center for Epidemiologic Studies Depression Scale (CESD-10), social support using the Medical Outcomes Survey scale (MOS-SSS), intimate partner violence (IPV) with the Hurt, Insult, Threaten, Scream scale (HITS), and pregnancy outcomes at 6 weeks postpartum. Cox proportional hazards models were used to evaluate relationships between depressive symptoms (moderate-to-severe [MSD, CESD-10 ≥10] and mild-to-severe [Mild-SD, CESD-10 ≥5]), low social support (MOS-SSS <72), and IPV (HITS ≥10) with adverse perinatal outcomes of pregnancy loss, stillbirth, preterm birth (PTB), small for gestational age, and neonatal mortality. We also estimated the population attributable risk.

RESULTS

Among 4153 women, 23.9% (n = 994) had MSD, 54.7% (n = 2273) mild-SD, 37.3% (n = 1550) low social support, and 7.8% (n = 323) experienced IPV. Pregnancy loss was 5-fold higher among women with MSD (adjusted hazard ratio [HR] 5.04, 95% confidence interval [CI] 2.44, 10.42); 37.4% of losses were attributable to MSD. Mild-SD was associated with PTB (HR 1.39, 95% CI 1.03, 1.87). Stillbirth risk more than doubled among women reporting low social support (HR 2.37, 95% CI 1.14, 4.94).

CONCLUSIONS

Adverse perinatal outcomes were common and associated with prenatal depressive symptoms and low social support in this large cohort of Kenyan mother-infant pairs.

Improvement of community health worker counseling skills through early childhood development (ECD) videos, supervision and mentorship: A mixed methods pre-post evaluation from Tanzania

BACKGROUND

Community health workers (CHWs) play significant roles in improving health practices in under- resourced communities. This study evaluated an early childhood development (ECD) project in Tanzania assessing the effect of mobile video use, supervision and mentorship to improve quality of CHW counseling skills.

METHODS

CHWs participating in the Malezi Project in Tabora Region were enrolled in a mixed methods pre-post evaluation. CHWs previously trained in UNICEF's Care for Child Development package were further trained in counselling caregivers on nurturing care and father engagement using videos. Health providers were trained to provide ECD-focused supervision/mentorship of CHWs in facilities and during home visits. At baseline and endline, CHWs completed interviews and trained study staff observed and scored CHW counseling sessions using a structured checklist which were reduced into six dimensions through principal component analysis: introduce, educate, ask, plan/problem solve, interact/encourage, and responsive care. Twenty-five in-depth interviews were completed with caregivers and four focus group discussions with CHWs were conducted.

RESULTS

Almost all (n = 107; 95%) 119 enrolled CHWs completed the expected eight observations (n = 471 baseline; n = 453 endline). At endline, more CHWs reported having one-on-one meetings with their supervisors (51% increasing to 75%; p < .0002) and that supervisors accompanied them to households for mentoring (60% increasing to 89%; p < .0001). We observed a shift in CHW counselling skills in clinic and home sessions. Scores in the categories of introduce, plan/problem solve, and interact/encourage significantly improved between baseline and endline; scores for ask and educate remained unchanged or decreased at both timepoints. Two-thirds of caregivers interviewed reported that father's involvement with their child increased due to CHW visits. Male participation increased in home observation sessions from 5.6% at baseline to 17.6% at endline (p < .0001).

CONCLUSION

Use of videos, supervision, and mentorship were associated with CHW performance improvements in providing nurturing care counselling and in father engagement, especially in home settings.

Effect of early childhood development interventions delivered by healthcare providers to improve cognitive outcomes in children at 0-36 months: a systematic review and meta-analysis

OBJECTIVE

To determine the effect of early childhood development interventions delivered by healthcare providers (HCP-ECD) on child cognition and maternal mental health.

DESIGN

Systematic review, meta-analysis.

SETTING

Healthcare setting or home.

PARTICIPANTS

Infants under 1 month of age.

INTERVENTIONS

HCP-ECD interventions that supported responsive caregiving, early learning and motor stimulation. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Health Technology Assessment Database, Database of Abstracts of Reviews of Effects and Cochrane Database of Systematic Reviews were searched until 15 November 2021. Studies reporting prespecified outcomes were pooled using standard meta-analytical methods.

MAIN OUTCOME MEASURES

Cognitive development in children at 0-36 months.

RESULTS

Forty-two randomised controlled trials with 15 557 infants were included in the narrative synthesis. Twenty-seven trials were included in the meta-analyses. Pooled data from 13 trials suggest that HCP-ECD interventions may improve cognitive outcomes in children between 0 and 36 months (Bayley Scales of Infant Development version IIII (BSID-III) mean difference (MD) 2.65; 95% CI 0.61 to 4.70; 2482 participants; low certainty of evidence). Pooled data from nine trials suggest improvements in motor development (BSID-III MD 4.01; 95% CI 1.54 to 6.48; 1437 participants; low certainty of evidence). There was no evidence of improvement in maternal mental health (standardised MD -0.13; 95% CI -0.28 to 0.03; 2806 participants; 11 trials; low certainty of evidence).

CONCLUSIONS

We report promising evidence, particularly for cognitive and motor outcomes, of the effect of HCP-ECD interventions. However, effect sizes were small, and the certainty of evidence ranged from very low to moderate. Additional high-quality research is required.

The effect of supervision on community health workers' effectiveness with households in rural South Africa: A cluster randomized controlled trial

BACKGROUND

Community health workers (CHWs) can supplement professional medical providers, especially in rural settings where resources are particularly scarce. Yet, outcomes of studies evaluating CHWs effectiveness have been highly variable and lack impact when scaled nationally. This study examines if child and maternal outcomes are better when existing government CHWs, who are perinatal home visitors, receive ongoing enhanced supervision and monitoring, compared to standard care.

METHODS AND FINDINGS

A cluster randomized controlled effectiveness trial was conducted comparing outcomes over 2 years when different supervision and support are provided. Primary health clinics were randomized by clinic to receive monitoring and supervision from either (1) existing supervisors (Standard Care (SC); n = 4 clinics, 23 CHWs, 392 mothers); or (2) supervisors from a nongovernmental organization that provided enhanced monitoring and supervision (Accountable Care [AC]; n = 4 clinic areas, 20 CHWs, 423 mothers). Assessments were conducted during pregnancy and at 3, 6, 15, and 24 months post-birth with high retention rates (76% to 86%). The primary outcome was the number of statistically significant intervention effects among 13 outcomes of interest; this approach allowed us to evaluate the intervention holistically while accounting for correlation among the 13 outcomes and considering multiple comparisons. The observed benefits were not statistically significant and did not show the AC's efficacy over the SC. Only the antiretroviral (ARV) adherence effect met the significance threshold established a priori (SC mean 2.3, AC mean 2.9, p < 0.025; 95% CI = [0.157, 1.576]). However, for 11 of the 13 outcomes, we observed an improvement in the AC compared to the SC. While the observed outcomes were not statistically significant, benefits were observed for 4 outcomes: increasing breastfeeding for 6 months, reducing malnutrition, increasing ARV adherence, and improving developmental milestones. The major study limitation was utilizing existing CHWs and being limited to a sample of 8 clinics. There were no major study-related adverse events.

CONCLUSIONS

Supervision and monitoring were insufficient to improve CHWs' impact on maternal and child outcomes. Alternative strategies for staff recruitment and narrowing the intervention outcomes to the specific local community problems are needed for consistently high impact.

From surviving to thriving: integrating mental health care into HIV, community, and family services for adolescents living with HIV

Adolescents are a crucial generation, with the potential to bring future social and economic success for themselves and their countries. More than 90% of adolescents living with HIV reside in sub-Saharan Africa, where their mental health is set against a background of poverty, familial stress, service gaps, and an HIV epidemic that is now intertwined with the COVID-19 pandemic. In this Series paper, we review systematic reviews, randomised trials, and cohort studies of adolescents living with and affected by HIV. We provide a detailed overview of mental health provision and collate evidence for future approaches. We find that the mental health burden for adolescents living with HIV is high, contributing to low quality of life and challenges with adherence to antiretroviral therapy. Mental health provision is scarce, infrastructure and skilled providers are missing, and leadership is needed. Evidence of effective interventions is emerging, including specific provisions for mental health (eg, cognitive behavioural therapy, problem-solving, mindfulness, and parenting programmes) and broader provisions to prevent drivers of poor mental health (eg, social protection and violence prevention). We provide evidence of longitudinal associations between unconditional government grants and improved mental health. Combinations of economic and social interventions (known as cash plus care) could increase mental health benefits. Scalable delivery models include task sharing, primary care integration, strengthening families, and a pyramid of provision that differentiates between levels of need, from prevention to the care of severe disorders. A turning point has now been reached, from which complacency cannot persist. We conclude that there is substantial need, available frameworks, and a growing evidence base for action while infrastructure and skill acquisition is built.

First 1,000 days: enough for mothers but not for children? Long-term outcomes of an early intervention on maternal depressed mood and child cognitive development: follow-up of a randomised controlled trial

BACKGROUND

Child cognitive development is often compromised in contexts of poverty and adversity, and these deficits tend to endure and affect the child across the life course. In the conditions of poverty and violence that characterise many low- and middle-income countries (LMIC), the capacity of parents to provide the kind of care that promotes good child development may be severely compromised, especially where caregivers suffer from depression. One avenue of early intervention focuses on the quality of the early mother-infant relationship. The aim of this study was to examine the long-term impact of an early intervention to improve the mother-infant relationship quality on child cognitive outcomes at 13 years of age. We also estimated the current costs to replicate the intervention.

METHOD

We re-recruited 333 children from an early childhood maternal-infant attachment intervention, 'Thula Sana', when the children were 13 years old, to assess whether there were impacts of the intervention on child cognitive outcomes, and maternal mood. We used the Kaufman Assessment Battery to assess the child cognitive development and the Patient Health Questionnaire (PHQ-9) and the Self-Reporting Questionnaire (SRQ-20) to assess maternal mental health.

RESULTS

Effect estimates indicated a pattern of null findings for the impact of the intervention on child cognitive development. However, the intervention had an effect on caregiver psychological distress (PHQ-9, ES = -0.17 [CI: -1.95, 0.05] and SRQ-20, ES = -0.30 [CI: -2.41, -0.19]), but not anxiety. The annual cost per mother-child pair to replicate the Thula Sana intervention in 2019 was estimated at ZAR13,365 ($780).

CONCLUSION

In a socio-economically deprived peri-urban settlement in South Africa, a home visiting intervention, delivered by community workers to mothers in pregnancy and the first six postpartum months, had no overall effect on child cognitive development at 13 years of age. However, those caregivers who were part of the original intervention showed lasting improvements in depressed mood. Despite the fact that there was no intervention effect on long-term child outcomes, the improvements in maternal mood are important.

A systematic review of screening for perinatal depression and anxiety in community-based settings

Screening for perinatal depression and anxiety in community-based maternal and child health settings may help close the detection and treatment gap among women at higher risk for these conditions. We aim to review perinatal depression and anxiety screening tools, timing, and follow-up processes for positive screens in community-based settings. We conducted a systematic review of the literature to identify papers describing screening and interventions for perinatal depression and anxiety in community-based settings. We identified 49 papers describing 47 studies of perinatal depression or anxiety screening in community-based settings. The Edinburgh Postnatal Depression Scale (EPDS) was the most frequently used screening tool. Referral and referral tracking for those who screened positive for symptoms were inadequately described. Types of training and technical assistance provided for screening varied widely. It is feasible and acceptable to screen for perinatal depression in community settings, but there is a need for systematic research examining which screening tools to use, the ideal frequency of screening, and referral completion rates. There is a lack of information regarding perinatal anxiety screening and a lack of uniformity in training regarding screening in community-based settings. Future studies should compare the efficacy of screening in community-based settings to screening in healthcare settings.

Barriers and facilitators to implementation of evidence-based task-sharing mental health interventions in low- and middle-income countries: a systematic review using implementation science frameworks

BACKGROUND

Task-sharing is a promising strategy to expand mental healthcare in low-resource settings, especially in low- and middle-income countries (LMICs). Research on how to best implement task-sharing mental health interventions, however, is hampered by an incomplete understanding of the barriers and facilitators to their implementation. This review aims to systematically identify implementation barriers and facilitators in evidence-based task-sharing mental health interventions using an implementation science lens, organizing factors across a novel, integrated implementation science framework.

METHODS

PubMed, PsychINFO, CINAHL, and Embase were used to identify English-language, peer-reviewed studies using search terms for three categories: "mental health," "task-sharing," and "LMIC." Articles were included if they: focused on mental disorders as the main outcome(s); included a task-sharing intervention using or based on an evidence-based practice; were implemented in an LMIC setting; and included assessment or data-supported analysis of barriers and facilitators. An initial conceptual model and coding framework derived from the Consolidated Framework for Implementation Research and the Theoretical Domains Framework was developed and iteratively refined to create an integrated conceptual framework, the Barriers and Facilitators in Implementation of Task-Sharing Mental Health Interventions (BeFITS-MH), which specifies 37 constructs across eight domains: (I) client characteristics, (II) provider characteristics, (III) family and community factors, (IV) organizational characteristics, (V) societal factors, (VI) mental health system factors, (VII) intervention characteristics, and (VIII) stigma.

RESULTS

Of the 26,935 articles screened (title and abstract), 192 articles underwent full-text review, yielding 37 articles representing 28 unique intervention studies that met the inclusion criteria. The most prevalent facilitators occur in domains that are more amenable to adaptation (i.e., the intervention and provider characteristics domains), while salient barriers occur in domains that are more challenging to modulate or intervene on-these include constructs in the client characteristics as well as the broader societal and structural levels of influence (i.e., the organizational, mental health system domains). Other notable trends include constructs in the family and community domains occurring as barriers and as facilitators roughly equally, and stigma constructs acting exclusively as barriers.

CONCLUSIONS

Using the BeFITS-MH model we developed based on implementation science frameworks, this systematic review provides a comprehensive identification and organization of barriers and facilitators to evidence-based task-sharing mental health interventions in LMICs. These findings have important implications for ongoing and future implementation of this critically needed intervention strategy, including the promise of leveraging task-sharing intervention characteristics as sites of continued innovation, the importance of but relative lack of engagement with constructs in macro-level domains (e.g., organizational characteristics, stigma), and the need for more delineation of strategies for task-sharing mental health interventions that researchers and implementers can employ to enhance implementation in and across levels.

Validation of community health worker identification of maternal puerperal sepsis using a clinical diagnostic algorithm in Bangladesh and Pakistan

Background

Puerperal sepsis (PP sepsis) is a leading cause of maternal mortality globally. The majority of maternal sepsis cases and deaths occur at home and remain undiagnosed and under-reported. In this paper, we present findings from a nested case-control study in Bangladesh and Pakistan which sought to assess the validity of community health worker (CHW) identification of PP sepsis using a clinical diagnostic algorithm with physician assessment and classification used as the gold standard.

Methods

Up to 300 postpartum women were enrolled in each of the 3 sites 1) Sylhet, Bangladesh (n = 278), 2) Karachi, Pakistan (n = 278) and 3) Matiari, Pakistan (n = 300). Index cases were women with suspected PP Sepsis as diagnosed by CHWs clinical assessment of one or more of the following signs and symptoms: temperature (recorded fever ≥38.1°C, reported history of fever, lower abdominal or pelvic pain, and abnormal or foul-smelling discharge. Each case was matched with 3 control women who were diagnosed by CHWs to have no infection. Cases and controls were assessed by trained physicians using the same algorithm implemented by the CHWs. Using physician assessment as the gold standard, Kappa statistics for reliability and diagnostic validity (sensitivity and specificity) are presented with 95% CI. Sensitivity and specificity were adjusted for verification bias.

Results

The adjusted sensitivity and specificity of CHW identification of PP sepsis across all sites was 82% (Karachi: 78%, Matiari: 78%, Sylhet: 95%) and 90% (Karachi: 95%, Matiari: 85%, Sylhet: 90%) respectively. CHW-Physician agreement was highest for moderate and high fever (range across sites: K = 0.84-0.97) and lowest for lower abdominal pain (K = 0.30-0.34). The clinical signs and symptoms for other conditions were reported infrequently, however, the CHW-physician agreement was high for all symptoms except severe headache/ blurred vision (K = 0.13-0.38) and reported "lower abdominal pain without fever" (K = 0.39-0.57).

Conclusion

In all sites, CHWs with limited training were able to identify signs and symptoms and to classify cases of PP sepsis with high validity. Integrating postpartum infection screening into existing community-based platforms and post-natal visits is a promising strategy to monitor women for PP sepsis - improving delivery of cohesive maternal and child health care in low resource settings.

Maternal depressed mood and child development over the first five years of life in South Africa

BACKGROUND

While the negative impact of peri-natal depression is well-documented in high-income countries, the long-term effects across the life course in low and middle-income countries is less clear. Children's adjustment over the first five years is examined as a function of patterns of maternal depressed mood.

METHODS

Pregnant women in 24 peri-urban townships (N = 1,238) were randomized to a home-visiting intervention or standard care and reassessed five times, with high retention. There were no intervention effects on children past 18 months. Multilevel regression models examined the impact of depressed mood on child outcomes. Using the Edinburgh Postnatal Depression Scale, four patterns of maternal depressed mood were identified: never (40.6%); antenatal (13.0%); early childhood (26.1%); and recurrent episodes of depressed mood (20.3 %).

FINDINGS

Mothers' patterns of depressive symptoms and child outcomes were similar, regardless of intervention. Never depressed mothers were significantly younger, had higher income, less food insecurity, were more likely to have electricity, be living with HIV or have an HIV positive partner, and had fewer problems with alcohol than depressed mothers. Children of mothers who experienced depressed mood weighed less, were more aggressive, and were hospitalized more often than children of never depressed mothers, but were similar in cognitive and social development.

INTERPRETATIONS

Depressed mood, has significant negative impacts on South African children's growth and aggressive behavior. The timing of maternal depressed mood was less important than never having a depressed mood or a recurrent depressed mood.

FUNDING

There were no funding conflicts in executing this trial.

Community health worker home visiting in deeply rural South Africa: 12-month outcomes

Home visiting by community health workers (CHW) improves child outcomes in efficacy trials, there is however limited evidence of impact evaluating CHW programmes when operating outside of a research project. A CHW programme, previously demonstrated efficacious in a peri-urban township, was evaluated in a deeply rural context in a non-randomised comparative cohort study. Two non-contiguous, rural areas in the Eastern Cape of South Africa of about equal size and density were identified and 1469 mother-infant pairs were recruited over 33 months. In one area, CHWs conducted perinatal home visits (intervention group). Mothers in the comparison group received standard clinic care. Maternal and child outcomes were compared between the groups at one year. Mothers in the intervention group had significantly fewer depressive symptoms than mothers in the comparison group. Children of intervention mothers attained a higher proportion of their developmental milestones, compared to children in the comparison group. There were no other significant differences between mothers and children in the two groups. It is important to establish key parameters for implementing efficacious CHW programmes, especially as the numbers of CHWs are rapidly increased and are becoming critical components of task-shifting strategies of health departments in low and middle income countries (LMIC).

Testing an Incentive-Based and Community Health Worker Package Intervention to Improve Maternal Health and Nutrition Outcomes: A Pilot Randomized Controlled Trial

OBJECTIVES

In order to address South Africa's maternal and infant mortality and morbidity rates, patient and community-level preventable factors need to be identified and addressed. However, there are few rigorously implemented and tested studies in low- and middle-income countries that evaluate the impact of community-level interventions on maternal and infant health outcomes. This study examined the impact of a package intervention, consisting of an incentive called the Thula Baba Box (TBB) and a community health worker (CHW) programme, on maternal depressive symptoms, maternal nutrition and intention to exclusively breastfeed.

METHOD

The intervention was tested using a pilot randomised controlled trial consisting of 72 (39 treatment and 33 control) adult women, implemented in a low-income, peri-urban area in Cape Town, South Africa. Data was collected using a baseline questionnaire conducted shortly after recruitment, and an end line questionnaire conducted a week after giving birth.

RESULTS

The intervention resulted in a 0.928-point drop in the maternal depressive symptom scale (which ranges from 1 to 8). We find no evidence that the intervention has either a sizeable or precisely estimated impact on maternal nutrition, measured using middle-upper arm circumference. While the intervention has almost no effect on the infant feeding intention of women who own refrigerators, it has a very large positive effect of 3.349-points (on a scale ranging from 1 to 8) for women without refrigerators.

CONCLUSION

A package intervention consisting of psycho-social support, additional tailored health information, and an incentive to utilise public antenatal care services has the potential to increase exclusive breastfeeding intention and reduce maternal depressive symptoms among the economically vulnerable.

Primary-level worker interventions for the care of people living with mental disorders and distress in low- and middle-income countries

BACKGROUND

Community-based primary-level workers (PWs) are an important strategy for addressing gaps in mental health service delivery in low- and middle-income countries.  OBJECTIVES: To evaluate the effectiveness of PW-led treatments for persons with mental health symptoms in LMICs, compared to usual care.  SEARCH METHODS: MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, ICTRP, reference lists (to 20 June 2019).   SELECTION CRITERIA: Randomised trials of PW-led or collaborative-care interventions treating people with mental health symptoms or their carers in LMICs.  PWs included: primary health professionals (PHPs), lay health workers (LHWs), community non-health professionals (CPs).  DATA COLLECTION AND ANALYSIS: Seven conditions were identified apriori and analysed by disorder and PW examining recovery, prevalence, symptom change, quality-of-life (QOL), functioning, service use (SU), and adverse events (AEs).  Risk ratios (RRs) were used for dichotomous outcomes; mean difference (MDs), standardised mean differences (SMDs), or mean change differences (MCDs) for continuous outcomes.  For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥0.80 large clinical effects.  Analysis timepoints: T1 (<1 month), T2 (1-6 months), T3 ( >6 months) post-intervention.  MAIN RESULTS: Description of studies 95 trials (72 new since 2013) from 30 LMICs (25 trials from 13 LICs).  Risk of bias Most common: detection bias, attrition bias (efficacy), insufficient protection against contamination.  Intervention effects *Unless indicated, comparisons were usual care at T2.  "Probably", "may", or "uncertain" indicates "moderate", "low," or "very low" certainty evidence.   Adults with common mental disorders (CMDs) LHW-led interventions a. may increase recovery (2 trials, 308 participants; RR 1.29, 95%CI 1.06 to 1.56); b. may reduce prevalence (2 trials, 479 participants; RR 0.42, 95%CI 0.18 to 0.96); c. may reduce symptoms (4 trials, 798 participants; SMD -0.59, 95%CI -1.01 to -0.16); d. may improve QOL (1 trial, 521 participants; SMD 0.51, 95%CI 0.34 to 0.69); e. may slightly reduce functional impairment (3 trials, 1399 participants; SMD -0.47, 95%CI -0.8 to -0.15); f. may reduce AEs (risk of suicide ideation/attempts); g. may have uncertain effects on SU.

PW-led interventions show promising benefits in improving outcomes for CMDs, PND, PTS, harmful alcohol/substance use, and dementia carers in LMICs.

Success Factors for Community Health Workers in Implementing an Integrated Group-Based Child Development Intervention in Rural Bangladesh

Community Health Workers (CHWs) can effectively implement maternal and child health interventions, but there is paucity of evidence on how to integrate child stimulation into these interventions, and their delivery at scale. In rural Bangladesh, CHWs implemented an intervention integrating psychosocial stimulation, nutrition, maternal mental health, water, sanitation, hygiene (WASH) and lead exposure prevention. In each of 16 intervention villages, one CHW worked with 20 households. CHWs bi-weekly held group meetings or alternated group meetings and home visits with pregnant women and lactating mothers. We assessed the intervention through five focus groups, four interviews and one group discussion with CHWs and their supervisors to explore success factors of implementation. CHWs’ training, one-on-one supervision and introduction by staff to their own community, and adoption of tablet computers as job aids, enabled successful session delivery to convey behavioral recommendations. CHWs reported difficulties delivering session due to the complexity of behavioral recommendations and struggled with age-specific intervention material. Young children’s attendance in group sessions generated distractions that undermined content delivery. We identified ways to minimize the difficulties to strengthen intervention-delivery during implementation, and scale-up. Iterative revisions of similarly integrated interventions based on qualitative evaluation findings could be delivered feasibly by CHWs and allow for implementation at scale.

Designing Evidence-Based Preventive Interventions That Reach More People, Faster, and with More Impact in Global Contexts

This article demonstrates the substantial similarities globally among preventive, evidence-based interventions (EBIs) designed to address HIV by providing four examples: an HIV family-focused intervention, the Community Popular Opinion Leader intervention, a South African maternal/child health program, and an EBI for sex workers in India. Each identified the key problems in the target population, utilized well-established social cognitive theories, created processes for engaging the target population, set standards for staff accountability, and included routine data collection to facilitate iterative program improvements over time. Building EBIs based on these common, robust features is an alternative design strategy to replication with fidelity. These components provide a road map for researchers, especially those using new technologies, and for local providers seeking to deliver EBIs that match their clients' and communities' needs. Technology platforms and community organizations may serve as resources for designers of the next generation of EBIs, offering an alternative to repeatedly validating the same interventions and replicating them with fidelity.

Impact of maternal mental health interventions on child-related outcomes in low- and middle-income countries: a systematic review and meta-analysis

AIMS

Observational studies have shown a relationship between maternal mental health (MMH) and child development, but few studies have evaluated whether MMH interventions improve child-related outcomes, particularly in low- and middle-income countries. The objective of this review is to synthesise findings on the effectiveness of MMH interventions to improve child-related outcomes in low- and middle-income countries (LMICs).

METHODS

We searched for randomised controlled trials conducted in LMICs evaluating interventions with a MMH component and reporting children's outcomes. Meta-analysis was performed on outcomes included in at least two trials.

RESULTS

We identified 21 trials with 28 284 mother-child dyads. Most trials were conducted in middle-income countries, evaluating home visiting interventions delivered by general health workers, starting in the third trimester of pregnancy. Only ten trials described acceptable methods for blinding outcome assessors. Four trials showed high risk of bias in at least two of the seven domains assessed in this review. Narrative synthesis showed promising but inconclusive findings for child-related outcomes. Meta-analysis identified a sizeable impact of interventions on exclusive breastfeeding (risk ratio = 1.39, 95% confidence interval (CI): 1.13-1.71, ten trials, N = 4749 mother-child dyads, I2 = 61%) and a small effect on child height-for-age at 6-months (std. mean difference = 0.13, 95% CI: 0.02-0.24, three trials, N = 1388, I2 = 0%). Meta-analyses did not identify intervention benefits for child cognitive and other growth outcomes; however, few trials measured these outcomes.

CONCLUSIONS

These findings support the importance of MMH to improve child-related outcomes in LMICs, particularly exclusive breastfeeding. Given, the small number of trials and methodological limitations, more rigorous trials should be conducted.

Community health workers impact on maternal and child health outcomes in rural South Africa - a non-randomized two-group comparison study

BACKGROUND

Home visits by paraprofessional community health workers (CHWs) has been shown to improve maternal and child health outcomes in research studies in many countries. Yet, when these are scaled or replicated, efficacy disappears. An effective CHW home visiting program in peri-urban Cape Town found maternal and child health benefits over the 5 years point but this study examines if these benefits occur in deeply rural communities.

METHODS

A non-randomized, two-group comparison study evaluated the impact of CHW in the rural Eastern Cape from August 2014 to May 2017, with 1310 mother-infant pairs recruited in pregnancy and 89% were reassessed at 6 months post-birth.

RESULTS

Home visiting had limited, but important effects on child health, maternal wellbeing and health behaviors. Mothers reported fewer depressive symptoms, attended more antenatal visits and had better baby-feeding practices. Intervention mothers were significantly more likely to exclusively breastfeed for 6 months (OR: 1.8; 95% CI: 1.1, 2.9), had lower odds of mixing formula with baby porridge (regarded as detrimental) (OR: 0.4; 95% CI: 0.2, 0.8) and were less likely to consult traditional healers. Mothers living with HIV were more adherent with co-trimoxazole prophylaxis (p < 0.01). Intervention-group children were significantly less likely to be wasted (OR: 0.5; 95% CI 0.3-0.9) and had significantly fewer symptoms of common childhood illnesses in the preceding two weeks (OR: 0.8; 95% CI: 0.7,0.9).

CONCLUSION

The impact of CHWs in a rural area was less pronounced than in peri-urban areas. CHWs are likely to need enhanced support and supervision in the challenging rural context.

Course of perinatal depressive symptoms among South African women: associations with child outcomes at 18 and 36 months

PURPOSE

Latent modelling was used to identify trajectories of depressive symptoms among low-income perinatal women in South Africa. Predictors of trajectories and the association of trajectories with child outcomes were assessed.

METHODS

This is a secondary analysis of data collected among women living in Cape Town settlements (N = 446). Participants were eligible if pregnant and 18 years or older, and included in the analysis if allocated to the control arm (routine perinatal care). Participants were excluded in case of non-singleton birth and baby death. Follow-up assessments were at 2 weeks, 6-, 18-, and 36-month postpartum. Trajectories of depressive symptoms were based on the Edinburgh Postnatal Depression Scale scores until 18-month postpartum, using latent class growth analysis. Child physical, cognitive, socio-emotional, and behavioural outcomes were assessed at 18 and/or 36 months. Univariate and multivariate regressions were used to identify predictors of trajectories and differences in child outcomes.

RESULTS

Four trajectories were identified: chronic low (71.1%), late postpartum (10.1%), early postpartum (14.4%), and chronic high (4.5%). Low social support, unwanted pregnancy, and risky drinking were associated with the chronic high trajectory; unemployment and HIV-positive status with the early postpartum trajectory; and intimate partner violence with the late postpartum trajectory. Weight-to-length and weight-for-age z-scores at 18 months, and weight-for-age z-scores, length-for-age z-scores, emotional symptom, and peer problem scores at 36 months differed across trajectories.

CONCLUSIONS

Severe depressive symptoms in postpartum period have a lasting effect on child physical and socio-emotional outcomes. Multiple screening throughout pregnancy and 1-year postpartum is essential.

Hearing care across the life course provided in the community

Untreated hearing loss is recognized as a growing global health priority because of its prevalence and harmful effects on health and well-being. Until recently, little progress had been made in expanding hearing care beyond traditional clinic-based models to incorporate public health approaches that increase accessibility to and affordability of hearing care. As demonstrated in numerous countries and for many health conditions, sharing health-care tasks with community health workers (CHWs) offers advantages as a complementary approach to expand health-service delivery and improve public health. This paper explores the possibilities of task shifting to provide hearing care across the life course by reviewing several ongoing projects in a variety of settings – Bangladesh, India, South Africa and the United States of America. The selected programmes train CHWs to provide a range of hearing-care services, from childhood hearing screening to management of age-related hearing loss. We discuss lessons learnt from these examples to inform best practices for task shifting within community-delivered hearing care. Preliminary evidence supports the feasibility, acceptability and effectiveness of hearing care delivered by CHWs in these varied settings. To make further progress, community-delivered hearing care must build on established models of CHWs and ensure adequate training and supervision, delineation of the scope of practice, supportive local and national legislation, incorporation of appropriate technology and analysis of programme costs and cost–effectiveness. In view of the growing evidence, community-delivered hearing care may now be a way forward to improve hearing health equity.

An Incentive-Based and Community Health Worker Package Intervention to Improve Early Utilization of Antenatal Care: Evidence from a Pilot Randomised Controlled Trial

Objectives One of the factors linked to South Africa's relatively high maternal mortality ratio is late utilization of antenatal care (ANC). Early utilization is especially important in South Africa due to the high HIV prevalence amongst pregnant women. This study examined the impact of a package intervention, consisting of an incentive called the Thula Baba Box (TBB) and a community health worker (CHW) programme, on early utilization of ANC. Methods A pilot randomised controlled trial consisting of 72 women aged 18 and older was conducted in an urban area in South Africa to evaluate the impact of the package intervention. Women were recruited and randomised into either intervention (n = 39) or control group (n = 33). The intervention group received both the TBB and monthly CHW visits, while the control group followed standard clinical practice. Both groups were interviewed at recruitment and once again after giving birth. The outcomes measured are the timing of first ANC visit and whether they attended more than four times. It is anticipated that the box will also have a beneficial impact on infant health outcomes, but these fall out of the scope of this study. Results Women in the intervention groups sought care on average 1.35 months earlier than the control group. They were also significantly more likely to attend at least four antenatal clinic visits. Conclusions for practice Given the South African context and the importance of early care-seeking behaviour to improve health outcomes of HIV-positive pregnant women, the intervention can help to improve maternal and neonatal health outcomes. Further research is needed to investigate the impact of the two interventions separately, and to see if these findings hold in other communities.

The association of maternal alcohol use and paraprofessional home visiting with children's health: A randomized controlled trial

OBJECTIVE

This study examines the effect of a home visiting intervention on maternal alcohol use, problematic drinking, and the association of home visiting and alcohol use on children's behavioral, cognitive, and health outcomes at 5 time points over 5 years.

METHOD

We analyzed 5,099 observations of 1,236 mothers and their children from pregnancy to 5 years postbirth, within a longitudinal cluster-randomized trial evaluating the effect of a home visiting intervention on mothers in Cape Town, South Africa. Paraprofessional home visitors coached mothers on coping with multiple risk factors, including a brief, 1-visit intervention on alcohol prevention in pregnancy. We assessed changes in maternal drinking over time in relation to the intervention, and then examined the impact of these drinking patterns on child outcomes over five years.

RESULTS

Drinking increased over the 5 years postbirth, but it was significantly lower in the intervention condition. Compared with abstinence, mothers' problematic drinking was associated with decreased child weight (-0.21 z-units) at all assessments, increased child aggressive behavior (3 to 7 additional symptoms), and decreased child performance on an executive functioning measure (the silly sounds task; odds ratio = .34) at 3 and 5 years. The intervention's effect was associated with increased child aggression (0.25 to 0.75 of 1 additional symptom), but the intervention appeared to decrease the effect of problem drinking on children's aggressive acts and executive functioning.

CONCLUSION

These findings support the need for sustained interventions to reduce alcohol use, especially for mothers who exhibit problematic drinking. Maternal drinking influences children's health and development over time. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Impact of lay health worker programmes on the health outcomes of mother-child pairs of HIV exposed children in Africa: A scoping review

Background

Increased demand for healthcare services in countries experiencing high HIV disease burden and often coupled with a shortage of health workers, has necessitated task shifting from professional health workers to Lay Health Workers (LHWs) in order to improve healthcare delivery. Maternal and Child Health (MCH) services particularly benefit from task-shifting to LHWs or similar cadres. However, evidence on the roles and usefulness of LHWs in MCH service delivery in Sub-Saharan Africa (SSA) is not fully known.

Objectives

To examine evidence of the roles and impact of lay health worker programmes focusing on Women Living with HIV (WLH) and their HIV-exposed infants (HEIs).

Methods

A scoping review approach based on Arksey and O’Malley’s guiding principles was used to retrieve, review and analyse existing literature. We searched for articles published between January 2008 and July 2018 in seven (7) databases, including: MEDLINE, Embase, PsycINFO, Joanna Briggs, The Cochrane Library, EBM reviews and Web of Science. The critical constructs used for the literature search were “lay health worker”, “community health worker”, “peer mentor”, “mentor mother,” “Maternal and Child health worker”, “HIV positive mothers”, “HIV exposed infants” and PMTCT.

Results

Thirty-three (33) full-text articles meeting the eligibility criteria were identified and included in the final analysis. Most (n = 13, 39.4%) of the included studies were conducted in South Africa and used a cluster RCT design (n = 13, 39.4%). The most commonly performed roles of LHWs in HIV specific MCH programmes included: community engagement and sensitisation, psychosocial support, linkage to care, encouraging women to bring their infants back for HIV testing and supporting default tracing. Community awareness on Mother to Child Transmission of HIV (MTCT), proper and consistent use of condoms, clinic attendance and timely HIV testing of HEIs, as well as retention in care for infected persons, have all improved because of LHW programmes.

Conclusion

LHWs play significant roles in the management of WLH and their HEIs, improving MCH outcomes in the process. LHW interventions are beneficial in increasing access to PMTCT services and reducing MTCT of HIV, though their impact on improving adherence to ART remains scanty. Further research is needed to evaluate ART adherence in LHW interventions targeted at WLH. LHW programmes can be enhanced by increasing supportive supervision and remuneration of LHWs.

Antenatal depressed mood and child cognitive and physical growth at 18-months in South Africa: a cluster randomised controlled trial of home visiting by community health workers

AIM

To examine the child outcomes at 18-months post-birth of a population cohort of women with antenatal depressed mood, half of whom were randomly chosen to receive perinatal home visits from community health workers during pregnancy.

METHOD

Pregnant women in 24 neighbourhoods (98% participation) were randomised by neighbourhood to: (1) standard clinic care (SC; 12 neighbourhoods; n = 594) or (2) the Philani Intervention Program, a home visiting intervention plus standard care (12 neighbourhoods; n = 644). The physical and cognitive outcomes of children of mothers with antenatally depressed mood (Edinburg Perinatal Depression Scale >13) in the intervention condition were compared at 18-months post-birth to children of mothers without depressed mood in pregnancy in both conditions.

RESULTS

More than a third of mothers had heightened levels of antenatal depressed mood (35%), similar across conditions. Antenatal depressed mood was significantly associated with being a mother living with HIV, using alcohol and food insecurity. At 18-months, the overall cognitive and motor scale scores on the Bayley Scales of Development were similar. However, 10.3% fewer children of mothers with antenatal depressed mood in the intervention condition had cognitive scores on the Bayley Scales that were less than 85 (i.e., s.d. = 2 lower than normal) compared with children of mothers with antenatal depressed mood in the SC condition. Intervention children of mothers with antenatal depressed mood were also significantly less likely to be undernourished (Weight-for-Age Z-scores < -2).

CONCLUSION

Cognitive development and child growth among children born to mothers with antenatal depressed mood can be improved by mentor mother home visitors, probably resulting from better parenting and care received early in life.

Adapting a perinatal empathic training method from South Africa to Germany

Background

Maternal mental health conditions are prevalent across the world. For women, the perinatal period is associated with increased rates of depression and anxiety. At the same time, there is widespread documentation of disrespectful care for women by maternity health staff. Improving the empathic engagement skills of maternity healthcare workers may enable them to respond to the mental health needs of their clients more effectively. In South Africa, a participatory empathic training method, the “Secret History” has been used as part of a national Department of Health training program with maternity staff and has showed promising results. For this paper, we aimed to describe an adaptation of the Secret History empathic training method from the South African to the German setting and to evaluate the adapted training.

Methods

The pilot study occurred in an academic medical center in Germany. A focus group (n = 8) was used to adapt the training by describing the local context and changing the materials to be relevant to Germany. After adapting the materials, the pilot training was conducted with a mixed group of professionals (n = 15), many of whom were trainers themselves. A pre-post survey assessed the participants’ empathy levels and attitudes towards the training method.

Results

In adapting the materials, the focus group discussion generated several experiences that were considered to be typical interpersonal and structural challenges facing healthcare workers in maternal care in Germany. These experiences were crafted into case scenarios that then formed the basis of the activities used in the Secret History empathic training pilot. Evaluation of the pilot training showed that although the participants had high levels of empathy in the pre-phase (100% estimated their empathic ability as high or very high), 69% became more aware of their own emotional experiences with patients and the need for self-care after the training. A majority, or 85%, indicated that the training was relevant to their work as clinicians and trainers, that it reflected the German situation, and that it may be useful ultimately to address emotional distress in mothers in the perinatal phase.

Conclusions

Our study suggests that it is possible to adapt an empathic training method developed in a South African setting and apply it to a German setting, and that it is well received by participants who may be involved in healthcare worker training. More research is needed to assess adaptations with other groups of healthcare workers in different settings and to assess empathic skill outcomes for participants and women in the perinatal period.

Postpartum maternal mental health is associated with cognitive development of HIV-exposed infants in Zimbabwe: a cross-sectional study

This study examines the cognitive profiles of infants born to HIV positive mothers in Zimbabwe. Caregivers with HIV exposed infants delivered in 30 clinics in two areas of Zimbabwe were recruited to the study. Of the 574 study participants, 562 caregiver-infant dyads with a biological HIV +ve mother and infant aged 0-24 months were interviewed. All infants were tested by a trained administrator for cognitive development on the Mullen Scales of Early Learning (MSEL). The Edinburgh Postnatal Depression Scale and Parental Stress Index-Short Form were completed by the mothers together with infant and caregiver socioeconomic characteristics. Linear regression models were used to relate cognitive development scores to maternal stress scores, maternal depression scores and infant HIV status adjusting for infant and caregiver characteristics, as well as socioeconomic factors. Higher maternal depression scores were associated with lower overall infant cognitive scores (adjusted mean difference (aMD) = -0.28; CI 95%:-0.50 to -0.06; p = 0.01) and in the expressive language (aMD = -0.14; CI 95%:-0.27 to -0.01; p = 0.04), fine motor skills (aMD = -0.17; CI 95%: -0.33 to -0.01; p = 0.03), gross motor (aMD = -0.22; CI 95%:-0.40 to -0.04; p = 0.02), and visual reception (aMD = -0.22; CI 95%:-0.40 to -0.05; p = 0.01) domains. Higher maternal stress was associated with poorer overall infant cognitive scores (aMD = -0.11; CI 95%:-0.20 to -0.02; p = 0.02) and in the specific domains of expressive language (aMD = -0.07; CI 95%:-0.12 to -0.01; p = 0.01), gross motor skills (aMD = -0.12; CI 95%:-0.18 to -0.05; p < 0.01) and visual reception (aMD = -0.09; CI 95%:-0.16 to -0.02; p = 0.02). Comparisons between the small number of HIV positive infants (n = 16) and the HEU infants (n = 381) showed the latter to have higher mean gross motor scores (50.3 vs. 40.6; p = 0.01). There was no evidence of difference by HIV status in the other MSEL domains or overall mean cognitive scores. Our findings demonstrate the association between maternal mood and stress levels and child cognitive functioning, particularly in expressive language and visual reception development. Although cross sectional data cannot shed light on the direction of this association, the study suggests that interventions to address maternal stress and depression symptoms may prove to be beneficial.

Maternal patterns of antenatal and postnatal depressed mood and the impact on child health at 3-years postpartum

OBJECTIVE

The consequences of maternal depressed mood on children's growth, health, and cognitive and language development are examined over the first 3 years of life.

METHOD

Pregnant women in 24 periurban township neighborhoods in Cape Town, South Africa (N = 1,238 mothers) were randomized by neighborhood to a home visiting intervention or a standard care condition. Reassessments were conducted for 93%-85% of mothers at 2-weeks, 6-, 18-, and 36-months postbirth. Regressions were conducted on measures of children's growth, behavior, language, and cognition to examine the impact of four patterns of depressed mood: antenatal only (n = 154, 13.8%), postnatal only (n = 272, 24.3%), antenatal and postnatal (n = 220, 19.7%), and no depressed mood on any assessment (n = 473, 42.3%).

RESULTS

Patterns of depressed mood were similar across intervention conditions. Depressed mothers were significantly less educated, had lower incomes, were less likely to be employed or to have electricity; were more likely to report problematic drinking of alcohol, experience food insecurity, interpersonal partner violence, and to be HIV seropositive. At 36 months, the pattern of maternal depressed mood over time was significantly associated with children's compromised physical growth, both in weight and height, and more internalizing and externalizing symptoms of behavior problems. Measures of language and cognition were similar across maternal patterns of depressed mood.

CONCLUSIONS

Mothers who report depressed mood face significantly more life challenges, both environmental stressors related to poverty and other problematic behaviors. More proximal, postnatal depressed mood appears to have a larger influence on their children, compared with antenatal depressed mood. (PsycINFO Database Record

Thirty-Six-Month Outcomes of a Generalist Paraprofessional Perinatal Home Visiting Intervention in South Africa on Maternal Health and Child Health and Development

Almost all pregnant women (98 %) in 24 Cape Town neighborhoods were randomized by neighborhood to (1) the standard care (SC) condition (n = 12 neighborhoods; n = 594 pregnant women) or (2) the Philani Intervention Program (PIP) in which home visits by Community Health Workers (CHW) were conducted (n = 12 neighborhoods; n = 644 pregnant women). At 36 months post-birth (84.6 % follow-up), PIP mothers were significantly less depressed compared to the SC mothers. Children in PIP were significantly less likely to be stunted (24.3 vs 18.1 %, p = 0.013), to have better vocabularies, and were less likely to be hospitalized than children in the SC condition. These data suggest home visits may need to continue for several years post-birth. Sustainable, scalable perinatal intervention models are needed in LMIC.

Mentor Mothers Program Improved Child Health Outcomes At A Relatively Low Cost In South Africa

In light of South Africa's high prenatal HIV prevalence and infant mortality rate, a cluster randomized controlled trial was conducted to evaluate an intervention called Philani+, which used community health workers (known as Mentor Mothers) to deliver pre- and postnatal home visits in Cape Town, South Africa, to improve maternal and child health. We assessed the costs and benefits of this intervention and made comparisons with other scenarios that depicted increased capacity and provision of nurse-delivered care. The recurrent cost of the twenty-four-month intervention was US$80,001. The major health outcomes analyzed were differences in the proportion of infants who were low birthweight, stunted, and suboptimally breastfed between intervention and control groups. Each case of low birthweight averted cost US$2,397; of stunted growth, US$2,454; and of suboptimal breastfeeding, US$1,618. Employment of community health workers was cost saving compared to that of nurses. Philani+ improved child health at a relatively low cost, considering the health system costs associated with low birthweight and undernutrition. The model could be suitable for replication in low-resource settings to improve child health in other countries.

To evaluate if increased supervision and support of South African Government health workers' home visits improves maternal and child outcomes: study protocol for a randomized control trial

Background

Concurrent epidemics of HIV, depression, alcohol abuse, and partner violence threaten maternal and child health (MCH) in South Africa. Although home visiting has been repeatedly demonstrated efficacious in research evaluations, efficacy disappears when programs are scaled broadly. In this cluster randomized controlled trial (RCT), we examine whether the benefits of ongoing accountability and supervision within an existing government funded and implemented community health workers (CHW) home visiting program ensure the effectiveness of home visiting.

Methods/Design

In the deeply rural, Eastern Cape of South Africa, CHW will be hired by the government and will be initially trained by the Philani Programme to conduct home visits with all pregnant mothers and their children until the children are 2 years old. Eight clinics will be randomized to receive either (1) the Accountable Care Condition in which additional monitoring and accountability systems that Philani routinely uses are implemented (4 clinics, 16 CHW, 450 households); or (2) a Standard Care Condition of initial Philani training, but with supervision and monitoring being delivered by local government structures and systems (4 clinics, 21 CHW, 450 households). In the Accountable Care Condition areas, the CHW’s mobile phone reports, which are time-location stamped, will be monitored and data-informed supervision will be provided, as well as monitoring growth, medical adherence, mental health, and alcohol use outcomes. Interviewers will independently assess outcomes at pregnancy at 3, 6, 15, and 24 months post-birth. The primary outcome will be a composite score of documenting maternal HIV/TB testing, linkage to care, treatment adherence and retention, as well as child physical growth, cognitive functioning, and child behavior and developmental milestones.

Discussion

The proposed cluster RCT will evaluate whether routinely implementing supervision and accountability procedures and monitoring CHWs’ over time will improve MCH outcomes over the first 2 years of life.

Adapting Current Strategies to Implement Evidence-Based Prevention Programs for Paraprofessional Home Visiting

This paper describes a strategy for using evidence-based interventions (EBI) that does not require replication and fidelity. Eight parents, identified as positive role models, conducted home visits for 101 low-income Latina and Korean pregnant women. The home visitors, called mentor mothers (MM), were trained in 10 of the practice elements common to 80% of child-focused EBI and how to apply these skills to support mothers in obesity prevention, to increase the duration of breastfeeding, and to reduce depression. MM reported the content and skills utilized on each home visit on mobile phones. Each MM made an average of 153 home visits (SD = 173.3), with 28 of these visits being phone contacts. Body mass index (BMI) at 6 months was significantly associated with the frequency of MM focused on coping with depression (r = .24), but was not related to practice elements used by MM. The duration of breastfeeding was significantly related to the frequency with which MM focused on the topic of breastfeeding (r = .28) and parenting (r = .3), and MM use of attending (r = .24) and relaxation (r = .27). Depression was significantly correlated with the frequency of addressing depression (r = .27), but not to practice elements. MM did use different strategies in the first 150 visits compared to their last 150 visits, reflecting data-informed supervision. Evidence synthesized from EBI was used as a novel training method, with real-time monitoring and data-informed supervision providing evidence of iterative quality improvements in MM behaviors over time, as well as a way for linking implementation processes to outcomes.

Is a Positive Developmental-Behavioral Screening Score Sufficient to Justify Referral? A Review of Evidence and Theory

In their recommendations on screening for autism and developmental disabilities, the American Academy of Pediatrics recommends referral subsequent to a positive screening result. In this article, we argue that positive screening results are not always sufficient to justify a referral. We show that although positive predictive values are often low, they actually overstate the probability of having a disorder for many children who screen positive. Moreover, recommended screening thresholds are seldom set to ensure that the benefits of referral will equal or exceed the costs and risk of harm, which is a necessary condition for an optimal threshold in decision analysis. Drawing on recent recommendations for the Institute of Medicine/National Academy of Medicine, we discuss the implications of this argument for pediatric policy, education, and practice. In particular, we recommend that screening policies be revised to ensure that the costs and benefits of actions recommended in the event of a positive screen are appropriate to the screening threshold. We recommend greater focus on clinical decision-making in the education of physicians, including shared decision-making with patients and their families. Finally, we recommend broadening the scope of screening research to encompass not only the accuracy of specific screening instruments, but also their ability to improve decision-making in the context of systems of care.

The Nexus Between Nutrition and Early Childhood Development

This article looks at both nutrition and early childhood stimulation interventions as part of an integrated life cycle approach to development. We build on recent systematic reviews of child development, which are comprehensive in regard to what is currently known about outcomes reported in key studies. We then focus particularly on implementation, scaling, and economic returns, drawing mainly on experience in low- and middle-income countries where undernutrition and poor child development remain significant public health challenges with implications across the life course.

Intimate Partner Violence and Depression Symptom Severity among South African Women during Pregnancy and Postpartum: Population-Based Prospective Cohort Study

BACKGROUND

Violence against women by intimate partners remains unacceptably common worldwide. The evidence base for the assumed psychological impacts of intimate partner violence (IPV) is derived primarily from studies conducted in high-income countries. A recently published systematic review identified 13 studies linking IPV to incident depression, none of which were conducted in sub-Saharan Africa. To address this gap in the literature, we analyzed longitudinal data collected during the course of a 3-y cluster-randomized trial with the aim of estimating the association between IPV and depression symptom severity.

METHODS AND FINDINGS

We conducted a secondary analysis of population-based, longitudinal data collected from 1,238 pregnant women during a 3-y cluster-randomized trial of a home visiting intervention in Cape Town, South Africa. Surveys were conducted at baseline, 6 mo, 18 mo, and 36 mo (85% retention). The primary explanatory variable of interest was exposure to four types of physical IPV in the past year. Depression symptom severity was measured using the Xhosa version of the ten-item Edinburgh Postnatal Depression Scale. In a pooled cross-sectional multivariable regression model adjusting for potentially confounding time-fixed and time-varying covariates, lagged IPV intensity had a statistically significant association with depression symptom severity (regression coefficient b = 1.04; 95% CI, 0.61-1.47), with estimates from a quantile regression model showing greater adverse impacts at the upper end of the conditional depression distribution. Fitting a fixed effects regression model accounting for all time-invariant confounding (e.g., history of childhood sexual abuse) yielded similar findings (b = 1.54; 95% CI, 1.13-1.96). The magnitudes of the coefficients indicated that a one-standard-deviation increase in IPV intensity was associated with a 12.3% relative increase in depression symptom severity over the same time period. The most important limitations of our study include exposure assessment that lacked measurement of sexual violence, which could have caused us to underestimate the severity of exposure; the extended latency period in the lagged analysis, which could have caused us to underestimate the strength of the association; and outcome assessment that was limited to the use of a screening instrument for depression symptom severity.

CONCLUSIONS

In this secondary analysis of data from a population-based, 3-y cluster-randomized controlled trial, IPV had a statistically significant association with depression symptom severity. The estimated associations were relatively large in magnitude, consistent with findings from high-income countries, and robust to potential confounding by time-invariant factors. Intensive health sector responses to reduce IPV and improve women's mental health should be explored.
