Developmental outcome of very low birth weight infants in a developing country

Longitudinal Change of Cup to Disc Ratio in Premature Infants with Enlarged Cup to Disc Ratio and Normal Intraocular Pressure

PURPOSE

To evaluate the longitudinal change of cup to disc ratio (CDR) in premature infants with enlarged CDR and normal intraocular pressure (IOP).

METHODS

This retrospective, observational study included 283 eyes of 283 premature infants at single center. Infants were divided into enlarged CDR and control groups. Data on demographics, gestational age (GA), birth weight (BW), vertical cup to disc ratio (vCDR), IOP, and corneal diameter were analyzed.

RESULTS

Of the 283 patients, 38 (13.4%) and 245 (86.6%) were in the enlarged CDR and control groups, respectively. In the enlarged CDR group, the vCDR and baseline IOP was 0.63 ± 0.12 and 12.7 ± 2.2 mmHg, respectively. In the control group, the vCDR and baseline IOP was 0.18 ± 0.05 and 10.9 ± 1.7 mmHg, respectively. The IOP at a GA of 40 weeks and at 1 and 2 years of age were significantly lower than that at baseline. The differences in vCDR between baseline and each follow-up visit were not significant. vCDR was negatively correlated with GA and BW; however, these correlations were not significant.

CONCLUSIONS

The vCDR did not significantly change up to age of 2 years of age in premature infants with enlarged CDR and normal IOP. However, close follow-up is needed until other reliable glaucoma examinations, such as optical coherence tomography and visual fields, can be possible.

Growth and neurodevelopmental outcomes of preterm and low birth weight infants in rural Kenya: a cross-sectional study

OBJECTIVE

Data on long-term outcomes of preterm (PT) and low birth weight (LBW) infants in countries with high rates of neonatal mortality and childhood stunting are limited, especially from community settings. The current study sought to explore growth and neurodevelopmental outcomes of PT/LBW infants from a rural community-based setting of Kenya up to 18 months adjusted age.

DESIGN

Cross-sectional study.

SETTING

Migori County, Kenya.

PARTICIPANTS

Three hundred and eighty-two PT/LBW infants (50.2% of those identified as eligible) from a cluster randomised control trial evaluating a package of facility-based intrapartum quality of care interventions for newborn survival consented for follow-up.

OUTCOME MEASURES

Caregiver interviews and infant health, growth and neurodevelopmental assessments were completed at 6, 12 or 18 months±2 weeks. Data included sociodemographic information, medical history, growth measurements and neurodevelopmental assessment using the Ten Questions Questionnaire, Malawi Developmental Assessment Tool and Hammersmith Infant Neurological Examination. Analyses were descriptive and univariate regression models. No alterations were made to planned data collection.

RESULTS

The final sample included 362 PT/LBW infants, of which 56.6% were moderate to late PT infants and 64.4% were LBW. Fewer than 2% of parents identified their child as currently malnourished, but direct measurement revealed higher proportions of stunting and underweight than in national demographic and health survey reports. Overall, 22.7% of caregivers expressed concern about their child's neurodevelopmental status. Neurodevelopmental delays were identified in 8.6% of infants based on one or more standardised tools, and 1.9% showed neurological findings indicative of cerebral palsy.

CONCLUSIONS

Malnutrition and neurodevelopmental delays are common among PT/LBW infants in this setting. Close monitoring and access to early intervention programmes are needed to help these vulnerable infants thrive.

Developmental outcomes of very low birth weight infants with catch-up head growth: a nationwide cohort study

BACKGROUND

As the survival rates of very low birth weight (VLBW) infants have increased, their neurodevelopmental outcomes are of concern. This study aims to determine the demographic and perinatal characteristics of premature infant according to head growth, identify clinical factors affecting growth catch-up, and explore differences in developmental outcomes according to catch-up states.

METHODS

This nationwide prospective cohort study of Korean Neonatal Network data analyzed premature infants with very low birth weight (< 1,500 g) between 2014 and 2017. A total of 253 eligible infants who had completed the Bayley Scales of Infant and Toddler Development, Third Edition, were assigned into two groups: a catch-up (CU) group with a head circumference above the 10th percentile and a no catch-up (NCU) group with a head circumference below the 10th percentile at 18-24 months of corrected age (CA).

RESULTS

Most (81.4%, 206/253) premature infants exhibited catch-up growth at 18-24 months of CA. Rates of microcephaly, intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), sepsis, necrotizing enterocolitis (NEC), length of NICU stay, ventilation care, and parenteral nutrition were significantly greater in the NCU group (P < 0.05). On multiple linear regression analysis, BPD status was the most influential clinical factor affecting catch-up head growth after adjusting for gestational age, birth weight, and birth head circumference (adjusted OR 4.586, 95% CI 1.960-10.729). At 18-24 months of CA, the NCU group exhibited lower developmental indices and a higher rate of developmental delay than the CU group. Motor developmental delay was the most significant factor relevant to catch-up head growth, and the motor development difference between the two groups was only statistically significant after adjusting for four major neonatal morbidities: IVH, BPD, sepsis, and NEC status (adjusted OR 10.727, 95% CI 1.922-59.868).

CONCLUSION

As association was observed between head growth catch-up status and developmental outcomes in VLBW infants at 18-24 months of CA. Key clinical factors associated with catch-up status included BPD and NEC status, length of parenteral nutrition, and ventilator care. Further study is needed to establish causality and explore additional factors that may influence developmental outcomes in this population.

Prevalence of neurodevelopmental delays in infants with perinatal HIV infection in comparison with HIV exposure in rural South Africa

BACKGROUND

Assessing neurodevelopmental functioning in early infancy is essential as this is a critical period for infant development. Infants born to mothers with HIV are at a greater risk of developmental delays than those born to mothers without HIV. In this study, we analyzed differences in early neurodevelopmental functioning for infants with HIV exposure versus HIV infection to inform infant screening and early intervention.

METHODS

Participants were recruited from community health centers in Mpumalanga Province, South Africa. Prenatally, mothers completed baseline demographic assessment at 8 to 24-week gestation periods. Infant neurodevelopment was assessed using the Bayley Infant Neurodevelopmental Screener (BINS) 12 months postnatally. Five areas of development were assessed: cognition, receptive communication, expressive communication, fine motor ability, and gross motor ability.

FINDINGS

Postnatal infant assessment using the BINS revealed that infants were at risk for neurodevelopmental delays across all domains assessed. Notably, infants exposed to HIV, regardless of HIV status, were 'at emerging risk' or 'at clear risk' for cognitive (43.5%), receptive communication (38.2%), expressive communication (53.1%), fine motor (49.9%), and gross motor delays (55.6%). Differences were noted by HIV status in the cognition domain, such that HIV-exposed infants were more likely to be at emerging or clear risk than HIV-infected infants. There was a different trend with gross motor delays, such that HIV-infected infants were at a greater risk for motor delays than HIV-exposed, uninfected infants.

CONCLUSION

Screening tools for this vulnerable population provide valuable early life assessment to determine infant needs for intervention and treatment planning. Such interventions may mitigate the impact of HIV status on neurodevelopmental health generally and cognition.

Developmental characteristics of young children in a low-income South African community

Adequate early childhood development is critical for later-life success. Developmental profiles of specific populations are required to support implementation of early intervention services. Three hundred fifty-three caregivers of children with mean age 17.9 months (SD = 10.5) were selected from a primary healthcare clinic. Overall positive identification of signs of a developmental delay, with the Bayley Scales of Infant and Toddler Development III, was 51.8% (n = 183). Logistic regression analysis determined the effect of age and gender on results. Prevalence of developmental delay increased with age from 33.1% for children under 12 months to 61.7% and 66.3% for children between 13-24 months and 25-36 months, respectively. Females were 1.82 times (95% CI [1.16, 2.85]) more likely to have had no signs of developmental delay; 2.30 times (95% CI [1.14, 4.65]) in motor and 2.06 times (95% CI [1.23, 3.45]) in adaptive behaviour domains. One-third of children presented with low levels of adaptive behaviour functioning. One hundred and one (28.6%) participants across age groups displayed superior social-emotional ability, possibly due to familial structures and relationships. One-third of children presented with poor adaptive behaviour function, attributed to cultural differences. This study contributes to information on developmental characteristics of children in South Africa.

Influence of pre-eclampsia on 2-year neurodevelopmental outcome of very-low-birth-weight infants

OBJECTIVE

To evaluate the influence of maternal pre-eclampsia on neurodevelopmental outcome in very-low-birth-weight (VLBW) infants at 6, 12, and 24 months of corrected age.

METHODS

We conducted a retrospective cohort study of singleton VLBW infants between 2011 and 2018. The participants were divided into three groups: (1) mothers without pre-eclampsia, (2) pre-eclampsia without severe features, and (3) pre-eclampsia with severe features. The Bayley Scales of Infant Development third edition (BSID-III) was used to assess the neurodevelopment of participants. A BSID-III score < 85 was defined as neurodevelopmental impairment (NDI).

RESULTS

Overall, 482 VLBW infants born to 482 mothers were enrolled, of whom 327 mothers did not have pre-eclampsia and 155 mothers had pre-eclampsia (58 without and 97 with severe features). The infants born to mothers with pre-eclampsia with severe features had the lowest BSID-III scores at 6, 12, and 24 months. After adjustments, maternal pre-eclampsia with severe features was significantly associated with cognitive NDI in their infants (adjusted odds ratio [aOR] 4.14) and language NDI (aOR 3.37) at 2 years of corrected age.

CONCLUSIONS

VLBW fetuses born to mothers with pre-eclampsia with severe features have poorer 2-year neurodevelopmental outcome, which mainly manifests in the cognitive and language domains.

Short-term neurodevelopment and growth outcomes of very and moderate preterm Indian infants

OBJECTIVE

To study the growth and neurodevelopmental outcome of very and moderate preterm infants (VMPT) compared to term appropriate-for-age (term AGA) infants at 18-months corrected age.

METHODS

This prospective cohort study enrolled consecutively born 212 VMPT infants and 250 term AGA controls delivered during study period.

OUTCOME MEASURES

Major neurodevelopmental impairment (NDI) defined as any one of cerebral palsy, motor (MoDQ) or mental developmental quotient (MoDQ) <70 on Developmental Assessment Scale for Indian infants, visual or hearing impairment, or epilepsy, and growth outcomes.

RESULTS

Among 195 VMPT and 240 term AGA infants who completed follow-up, the frequency of major NDI was 12.8% and 2.5% respectively (RR 5.1; 95% CI [2.13-12.19]). Major NDI was higher among infants <28 weeks gestation (39%) and birthweight <1000 grams (27%). A quarter of VMPT infants exhibited wasting and 18% stunting than 7% each among controls.

CONCLUSION

VMPT infants had a higher frequency of major NDI and growth failure at 18-months.

An evaluation of a combined psychological and parenting intervention for HIV-positive women depressed in the perinatal period, to enhance child development and reduce maternal depression: study protocol for the Insika Yomama cluster randomised controlled trial

BACKGROUND

The combination of poverty, HIV and depression in the perinatal period represents a major public health challenge in many Southern African countries. In some areas, up to a third of HIV-positive women experience perinatal depression. Perinatal depression is associated with negative effects on parenting and key domains of child development including cognitive, behavioural and growth, especially in socio-economically disadvantaged communities. Several studies have documented the benefits of psychological interventions for perinatal depression in low- and middle-income countries, but none have evaluated an integrated psychological and parenting intervention for HIV-positive women using task-sharing. This randomised controlled trial aims to evaluate the effect of a home-based intervention, combining a psychological treatment for depression and a parenting programme for perinatally depressed HIV-positive women.

METHODS

This study is a cluster randomised controlled trial, consisting of 48-60 geospatial clusters. A total of 528 pregnant HIV-positive women aged ≥ 16 years who meet the criteria for depression on the Edinburgh Postnatal Depression Scale (EPDS, score ≥ 9)) are recruited from antenatal clinics in rural KwaZulu-Natal, South Africa. The geospatial clusters are randomised on an allocation ratio of 1:1 to either the intervention or Enhanced Standard of Care (ESoC). The intervention group receives 10 home-based counselling sessions by a lay counsellor (4 antenatal and 6 postnatal sessions) and a booster session at 16 months. The intervention combines behavioural activation for depression with a parenting programme, adapted from the UNICEF/WHO Care for Child Development programme. The ESoC group receives two antenatal and two postnatal counselling support and advice telephone calls. In addition, measures have been taken to enhance the routine standard of care. The co-primary outcomes are child cognitive development at 24 months assessed on the cognitive subscale of the Bayley Scales of Infant Development-Third Edition and maternal depression at 12 months measured by the EPDS.

ANALYSIS

The primary analysis will be a modified intention-to-treat analysis. The primary outcomes will be analysed using mixed-effects linear regression.

DISCUSSION

If this treatment is successful, policymakers could use this model of mental healthcare delivered by lay counsellors within HIV treatment programmes to provide more comprehensive services for families affected by HIV.

Global prevalence of long-term neurodevelopmental impairment following extremely preterm birth: a systematic literature review

Objective

Neurodevelopmental impairment (NDI) is a major complication of extreme prematurity. This systematic review was conducted to summarize the worldwide long-term prevalence of NDI associated with extreme prematurity.

Methods

Embase and MEDLINE databases were searched for epidemiologic and observational/real-world studies, published in English between 2011 and 2016, reporting long-term prevalence of NDI (occurring from 1 year) among extremely preterm infants born at gestational age (GA) ≤28 weeks.

Results

Of 2406 articles identified through searches, 69 met the protocol NDI definition (24 North America, 25 Europe, 20 Rest of World). Prevalence of any severity NDI in North America was 8%–59% at 18 months to 2 years, and 11%–37% at 2–5 years; prevalence of moderate NDI in Europe was 10%–13% at 18 months to 2 years, 3% at 2–5 years, and 9%–19% at ≥5 years; prevalence of any NDI in Rest of World was 15%–61% at 18 months to 2 years, and 42% at 2–5 years (no North America/Rest of World studies reported any NDI at ≥5 years). A trend toward higher prevalence of NDI with lower GA at birth was observed.

Conclusions

Extreme prematurity has a significant long-term worldwide impact on neurodevelopmental outcomes.

Neurologic Complications of Poverty: the Associations Between Poverty as a Social Determinant of Health and Adverse Neurologic Outcomes

PURPOSE OF REVIEW

Increasing attention has been paid in recent decades to social determinants of health as a risk factor for disease development and disease severity. While traditionally heart disease, family history, lipid profile, and tobacco use have all been associated with increased risk of neurological disease, numerous studies now show that the influence of poverty may be just as strong a risk factor. This study summarizes the recent literature on poverty as it contributes to neurological disease.

RECENT FINDINGS

Children growing up in poverty have increased risk for cognitive deficits and behavioral disorders as reported by Noble et al. (Dev Sci. 9(6):642-54, 2006) and Farah et al. (Brain Res. 1110(1):166-74, 2006) as well as worse outcomes when it comes to epilepsy management and disease course as discussed by Camfield et al. (Epilepsia. 57(11):1826-33, 2016). In adulthood, as the number of social determinants of health increases, the incidence of stroke and severe stroke increases significantly as reported by Reshetnyak et al. (Stroke. 51:2445-53, 2020) as does exposure to neurologically significant infectious diseases and incidence of dementia as reported by Sumilo et al. (Rev Med Virol. 18(2):81-95, 2008) and Zuelsdorff et al. (Alzheimer's Dement. 6(1):e12039, 2020). Social determinants of health including poverty should be considered a risk factor for disease. More attention is needed from clinicians as well as from a public health perspective to address this disparity.

HIV exposure and neurodevelopmental outcome in very low birth weight infants in a low-middle income setting: a prospective cohort study

Neurodevelopmental impairment is common in premature infants. We aimed to describe neurodevelopmental outcomes in very low birth weight (VLBW) infants at 12 months postmenstrual age (PMA) and correlated with maternal HIV status. A single-centre, prospective cohort study was conducted from 1 June 2017 to 31 January 2019 with follow-up to 12 months. In-born infants with birth weight <1500 g were enrolled. Follow-up care was provided to 12 months PMA. Participants provided informed consent and ethics approval was obtained. A total of 279 patients were enrolled of which 84 (30.1%) died before 12 months and 91 (32.6%) were lost to follow-up. Neurodevelopmental assessment was performed on 104 participants. Mean general development quotient was 106.8, 2 (2.0%) patients had moderate-to-severe impairment and 1 (1.0%) mild impairment. HIV exposure was associated with lower developmental scores (104.3 vs. 109.0; p=0.005), whilst antenatal treatment with magnesium sulphate (109.6 vs. 105.2; p=0.01) and breastfeeding (108.0 vs. 104.0; p = 0.03) were associated with higher developmental scores. Neurodevelopmental outcome at 12 months PMA correlated with maternal HIV status. HIV exposure in VLBW infants is associated with lower neurodevelopmental scores at 12 months PMA. Antenatal treatment with magnesium sulphate and breastfeeding are associated with improved outcomes.

Stigma toward small babies and their mothers in Ghana: A study of the experiences of postpartum women living with HIV

Infants born to HIV-infected mothers are more likely to be low birthweight (LBW) than other infants, a condition that is stigmatized in many settings worldwide, including sub-Saharan Africa. Few studies have characterized the social-cultural context and response to LBW stigma among mothers in sub-Saharan Africa or explored the views of women living with HIV (WLHIV) on the causes of LBW. We purposively sampled thirty postpartum WLHIV, who had given birth to either LBW or normal birthweight infants, from two tertiary hospitals in Accra, Ghana. Using semi-structured interviews, we explored women's understanding of the etiology of LBW, and their experiences of caring for a LBW infant. Interviews were analyzed using interpretive phenomenology. Mothers assessed their babies' smallness based on the baby's size, not hospital-recorded birthweight. Several participants explained that severe depression and a loss of appetite, linked to stigma following an HIV diagnosis during pregnancy, contributed to infants being born LBW. Women with small babies also experienced stigma due to the newborns' "undesirable" physical features and other people's unfamiliarity with their size. Consequently, mothers experienced blame, reluctance showing the baby to others, and social gossip. As a result of this stigma, women reported self-isolation and depressive symptoms. These experiences were layered on the burden of healthcare and infant feeding costs for LBW infants. LBW stigma appeared to attenuate with increased infant weight gain. A few of the women also did not breastfeed because they thought their baby's small size indicated pediatric HIV infection. Among WLHIV in urban areas in Ghana, mother and LBW infants may experience LBW-related stigma. A multi-component intervention that includes reducing LBW incidence, treating antenatal depression, providing psychosocial support after a LBW birth, and increasing LBW infants' weight gain are critically needed.

Nutrition, growth, and other factors associated with early cognitive and motor development in Sub-Saharan Africa: a scoping review

BACKGROUND

Food insecurity, poverty and exposure to infectious disease are well-established drivers of malnutrition in children in Sub-Saharan Africa. Early development of cognitive and motor skills - the foundations for learning - may also be compromised by the same or additional factors that restrict physical growth. However, little is known about factors associated with early child development in this region, which limits the scope to intervene effectively. To address this knowledge gap, we compared studies that have examined factors associated with early cognitive and/or motor development within this population.

METHODS

Predetermined criteria were used to examine four publication databases (PsycInfo, Embase, Web of Science and Medline) and identify studies considering the determinants of cognitive and motor development in children aged 0-8 years in Sub-Saharan Africa.

RESULTS

In total, 51 quantitative studies met the inclusion criteria, reporting on 30% of countries across the region. Within these papers, factors associated with early child development were grouped into five themes: Nutrition, Growth and Anthropometry, Maternal Health, Malaria and HIV, and Household. Food security and dietary diversity were associated with positive developmental outcomes, whereas exposure to HIV, malaria, poor maternal mental health, poor sanitation, maternal alcohol abuse and stunting were indicators of poor cognitive and motor development.

DISCUSSION

In this synthesis of research findings obtained across Sub-Saharan Africa, factors that restrict physical growth are also shown to hinder the development of early cognitive and motor skills, although additional factors also influence early developmental outcomes. The study also reviews the methodological limitations of conducting research using Western methods in sub-Saharan Africa.

Developmental status of human immunodeficiency virus-exposed uninfected premature infants compared with premature infants who are human immunodeficiency virus unexposed and uninfected

Background

There is growing concern about the developmental outcome of infants exposed to HIV in utero. HIV-infected women are at greater risk of premature delivery which poses a further developmental risk factor.

Objectives

To determine whether there is a difference between the development of premature infants born at 28–37 weeks gestational age that are HIV exposed but uninfected (HEU) compared with HIV-unexposed uninfected infants (HUU).

Method

A cross-sectional study was conducted in a Johannesburg state hospital. Thirty HEU and 30 HUU infants, aged between 16 days and six months, were assessed using the Bayley Scales of Infant and Toddler Development III.

Results

The two groups were well matched for gestational age and birth weight; however, more HUU infants presented with neonatal complications. HUU infants had lower developmental scores than HEU infants in the language (p = 0.003) and motor (p = 0.037) subscales. Expressive language was more affected in the HUU infants (p = 0.001), and fine (p = 0.001) and gross motor (p = 0.03) were affected as well. HUU infants with neonatal complications such as meningitis (p = 0.02) and neonatal jaundice (NNJ) (p = 0.01) are more likely to present with language and motor delay.

Conclusion

Meningitis and NNJ have more impact on infant development than in-utero HIV and ARV exposure.

Clinical implications

It is important for all premature infants to be screened regularly in order to diagnose developmental delays early so as to ensure early intervention and improved quality of life.

Association between maternal acetaminophen use and adverse birth outcomes in a pregnancy and birth cohort

INTRODUCTION

Acetaminophen is the only analgesic recommended for use during pregnancy. This use has recently been linked to childhood developmental disorders, a finding that requires further investigation. Adverse birth outcomes-preterm birth, low birthweight, and small for gestational age-are associated with increased risk of developmental disorders and can serve as intermediate outcomes when examining the impact of maternal acetaminophen use.

METHODS

Clinical and lifestyle-factor data were gathered from 1200 women within the Ontario Birth Study who delivered between January 2013 and June 2017. Poisson regression with robust error variance was used to estimate the relationship between acetaminophen use before and during pregnancy and low birthweight, preterm birth, and small for gestational age.

RESULTS

Offspring of mothers who used acetaminophen before pregnancy had a higher risk of low birthweight and small for gestational age. Acetaminophen use <once/week was associated with small for gestational age, adjusted relative risk (aRR) = 1.46 (95% CI 1.02, 2.11). Acetaminophen use ≥once/week was associated with both small for gestational age, RR = 1.82 (95% CI 1.12, 2.94), and low birthweight, aRR = 2.16 (95% CI 1.02, 4.54). Acetaminophen use during pregnancy was not associated with the examined outcomes.

CONCLUSIONS

Prepregnancy acetaminophen use may be associated with higher risk of adverse birth outcomes.

Neuroimaging young children and associations with neurocognitive development in a South African birth cohort study

Magnetic resonance imaging (MRI) is an indispensable tool for investigating brain development in young children and the neurobiological mechanisms underlying developmental risk and resilience. Sub-Saharan Africa has the highest proportion of children at risk of developmental delay worldwide, yet in this region there is very limited neuroimaging research focusing on the neurobiology of such impairment. Furthermore, paediatric MRI imaging is challenging in any setting due to motion sensitivity. Although sedation and anesthesia are routinely used in clinical practice to minimise movement in young children, this may not be ethical in the context of research. Our study aimed to investigate the feasibility of paediatric multimodal MRI at age 2–3 years without sedation, and to explore the relationship between cortical structure and neurocognitive development at this understudied age in a sub-Saharan African setting. A total of 239 children from the Drakenstein Child Health Study, a large observational South African birth cohort, were recruited for neuroimaging at 2–3 years of age. Scans were conducted during natural sleep utilising locally developed techniques. T1-MEMPRAGE and T2-weighted structural imaging, resting state functional MRI, diffusion tensor imaging and magnetic resonance spectroscopy sequences were included. Child neurodevelopment was assessed using the Bayley-III Scales of Infant and Toddler Development. Following 23 pilot scans, 216 children underwent scanning and T1-weighted images were obtained from 167/216 (77%) of children (median age 34.8 months). Furthermore, we found cortical surface area and thickness within frontal regions were associated with cognitive development, and in temporal and frontal regions with language development (beta coefficient ≥0.20). Overall, we demonstrate the feasibility of carrying out a neuroimaging study of young children during natural sleep in sub-Saharan Africa. Our findings indicate that dynamic morphological changes in heteromodal association regions are associated with cognitive and language development at this young age. These proof-of-concept analyses suggest similar links between the brain and cognition as prior literature from high income countries, enhancing understanding of the interplay between cortical structure and function during brain maturation.

Prevalence of Low Birth Weight and Prematurity and Associated Factors in Neonates in Ethiopia: Results from a Hospital-based Observational Study

Background

Low birth weight and prematurity are associated with increased morbidity, mortality and multiple short and long-term complications, exerting impacts on the individual, the families, the community and the health care system. Fetal, maternal and environmental factors have been associated with low birth weight and prematurity, based primarily on researches from high-income countries. It is unknown whether these risk factors are the same in low and middle income countries. The aims of this study are to determine the prevalence of low birth weight and prematurity and associated factors in Jimma University Specialized Hospital, Ethiopia.

Methods

This observational study was conducted at Jimma University Specialized Hospital, Ethiopia, from December 2014 to September 2016. Multivariable logistic regression was used to determine the associated factors, with results reported as odds ratios (OR) and 95% confidence intervals (CI).

Results

The prevalence of low birth weight and prematurity were 14.6% and 10.2%, respectively. The mean birth weight was 2,975g (standard deviation 494). Prematurity (OR 23.54, 95%CI 15.35-36.08, p<0.001) and unmarried marital status (OR 5.73, 95%CI 1.61-20.40, p=0.007) were positively associated with low birth weight. Female sex (OR 1.69, 95%CI 1.18-2.42, p=0.004) and unmarried marital status (OR 4.07, 95%CI 1.17-14.14, p=0.027) were positively associated with prematurity.

Conclusion

The prevalence of lower birth weight and prematurity in this study is lower than other studies reported from similar facilities. Prematurity and unmarried marital status are associated with LBW whereas female sex and unmarried marital status are associated with prematurity in this population.

Pattern of Cerebral Palsy Among Sudanese Children Less Than 15 Years of Age

BACKGROUND

Cerebral palsy (CP) is a non-progressive, everlasting neurological disorder of movement, posture, and physical activities, with a prevalence of 2.2-3.3/1,000. CP is a condition that occurs globally, with a similar prevalence in both developed and undeveloped countries. However, the etiology differs according to the socioeconomic status of the countries. The objective is to determine the pattern and the contributing factors of CP among Sudanese children.

METHODS

This was a retrospective hospital-based study conducted over a period of three years in a pediatric referral hospital in Khartoum, Sudan. One hundred and eight patients of CP were enrolled, of whom 59 (54.6%) were males and 49 (45.4%) were females.

RESULTS

Spastic quadriplegic CP was the most common type. Most cases were from lower social classes. Prenatal, antenatal, and unclassified CP were found in 45 (41.7%), 31 (28.7.%), 23 (21.3%), and 9 (8.3%) cases, respectively. Birth asphyxia, neonatal jaundice, Toxoplasma gondii, rubella virus, cytomegalovirus, herpes simplex virus infections (TORCH), and sepsis (acquired) were the main causative factors.

CONCLUSION

Spastic quadriplegia is the most common type of CP. Most of the cases had a direct positive relationship with socioeconomic status. The prenatal period was the most common period for the development of CP.

Cognitive Outcomes of Children with Very Low Birth Weight at 3 to 5 Years of Age

BACKGROUND

The cognitive consequences and risk factors based long-term outcome of very-low-birth-weight (VLBW; < 1,500 g) infants in Korea has not been studied. The aim of this study was to determine the influence of perinatal and neonatal risk factors on the cognitive performance of VLBW children at 3 to 5 years of age.

METHODS

We enrolled 88 VLBW infants without cystic periventricular leukomalacia for the assessment of their demographic data, cognitive performance, and development of cerebral palsy (CP) at 3 to 5 years of age. Cognitive performance was assessed using the Korean version of the Wechsler Preschool and Primary Scale of Intelligence IV. Growth data were assessed with measurements of weight, height, and head circumference (HC) at the corrected ages of 6, 12, and 18 months, and 3 to 5 years of age.

RESULTS

In the VLBW group, the full-scale intelligence quotient (FSIQ) was 96.1 ± 15.2 at the mean age of 4.5 years. The incidence rate of CP was 3.4%. Overall, 17% (15/88) of the VLBW children had a below-average FSIQ (< 85). We divided the VLBW children into the abnormal FSIQ group (< 85, n = 15) and the normal FSIQ group (≥ 85, n = 73). VLBW children with intrauterine growth retardation (IUGR) was associated with a below-average FSIQ at the mean age of 4.5 years (< 85, 8/15, 53.3% vs. ≥ 85, 5/73, 6.8%; P < 0.001). After controlling for associated clinical factors, IUGR in the VLBW children was found to be associated with an abnormal FSIQ at the mean age of 4.5 years (P = 0.025). The weight, height, and HC obtained for both groups showed that normal growth was maintained at the mean age of 4.5 years with no significant difference between abnormal and normal FSIQ groups.

CONCLUSION

Fifteen of 88 (17%) of the VLBW children had a below-average FSIQ (< 85). VLBW with IUGR is associated with poor cognitive outcomes at the mean age of 4.5 years.

Association between birth weight and neurodevelopment at age 1-6 months: results from the Wuhan Healthy Baby Cohort

OBJECTIVE

The association between birth weight and infants' neurodevelopment is not well understood. We aimed to examine the impact of birth weight on neurodevelopment of infants at age 1-6 months using data from the Wuhan Healthy Baby Cohort (WHBC) study.

SETTING AND PARTICIPANTS

This is a prospective cohort study of 4026 infants from the WHBC study who were born at the Women and Children's Hospital of Wuhan, China between October 2012 and September 2013 and who had complete healthcare records within 6 months after birth. Participants were categorised into three groups according to their birth weight: low birth weight (LBW; birth weight <2500 g), normal birth weight (2500 g ≤ birth weight <4000 g) and macrosomia (birth weight ≥4000 g).

MAIN OUTCOME MEASURES

The main outcomes were development quotient (DQ) and clinical diagnosis of neurodevelopmental delay. Both adjusted regression coefficients and ORs were estimated for LBW and macrosomia.

RESULTS

Of the 4026 infants, 166 (4.12%) were of LBW and 237 (5.89%) were with macrosomia. Adjusted regression coefficients of LBW and macrosomia for gross motor DQ were -11.18 (95% CI -11.36 to 10.99) and 0.49 (95% CI 0.36 to 0.63), fine motor DQ -6.57 (95% CI -6.76 to -6.39) and -2.73 (95% CI -2.87 to -2.59), adaptability DQ -4.87 (95% CI -5.05 to -4.68) and -1.19 (95% CI -1.33 to -1.05), language DQ -6.23 (95% CI -6.42 to -6.05) and 0.43 (95% CI 0.29 to 0.57), and social behaviour DQ -6.82 (95% CI -7.01 to -6.64) and 1.10 (95% CI 0.96 to 1.24). Adjusted OR of LBW for clinical diagnosis of 'neurodevelopmental delay' in gross motor was 2.43 (95% CI 1.65 to 3.60), fine motor 1.49 (95% CI 1.01 to 2.19) and adaptability 1.56 (95% CI 1.06 to 2.31). LBW has no significant effects on 'neurodevelopmental delay' in language and social behaviour, and macrosomia has no significant effects on clinical diagnosis of 'neurodevelopmental delay' in all domains.

CONCLUSION

Both LBW and macrosomia are associated with infants' DQ, and LBW increases the risk of being diagnosed with 'neurodevelopmental delay' in gross motor, fine motor and adaptability among infants aged 1-6 months.

Transitioning Into the Role of Mother Following the Birth of a Very Low-Birth-Weight Infant: A Grounded Theory Pilot Study

This qualitative grounded theory pilot study investigated the concerns and coping mechanisms of mothers of very low-birth-weight (VLBW; <1500 g) infants following discharge from the neonatal intensive care unit in Alberta, Canada. In-depth, semistructured, face-to-face, audio-recorded interviews were conducted with women of VLBW infants. Interviews lasting 75 to 90 minutes were transcribed verbatim and coded using grounded theory methodology. Data saturation and theoretical redundancy were achieved in interviews with 6 mothers of VLBW infants. The core variable of "reconstructing normal" emerged from the interview data. Women indicated that mothering a VLBW infant is an unfolding experience that is continuously being revised, creating a new sense of normal. The construct consists of 4 categories; mother-infant relationship, maternal development, maternal caregiving and role-reclaiming strategies, and infant developmental milestones. Findings from this study suggest that women found the transition into motherhood following the birth of a VLBW infant as a multidimensional and dynamic process. Further research is warranted to confirm these results and to further explore mothering issues with VLBW infants.

Associations of antenatal maternal psychological distress with infant birth and development outcomes: Results from a South African birth cohort

BACKGROUND

Antenatal maternal psychological distress is common in low and middle-income countries (LMIC), but there is a dearth of research on its effect on birth and developmental outcomes in these settings, particularly in Sub-Saharan Africa. This study set out to identify risk factors for antenatal maternal psychological distress and determine whether antenatal maternal psychological distress was associated with infant birth and developmental outcomes, using data from the Drakenstein Child Health Study (DCHS), a birth cohort study in South Africa.

METHODS

Pregnant women were enrolled in the DCHS from primary care antenatal clinics. Antenatal maternal psychological distress was measured using the Self-Reporting Questionnaire 20-item (SRQ-20). A range of psychosocial measures, including maternal childhood trauma, depression, and posttraumatic stress disorder (PTSD) were administered. Birth outcomes, including premature birth, weight-for-age z-score and head circumference-for-age z-score, were measured using revised Fenton growth charts. The Bayley III Scales of Infant and Toddler Development was administered at 6 months of age to assess infant development outcomes, including cognitive, language, and motor domains in a subset of n=231. Associations of maternal antenatal psychological distress with psychosocial measures, and with infant birth and developmental outcomes were examined using linear regression models.

RESULTS

961 women were included in this analysis, with 197 (21%) reporting scores indicating the presence of psychological distress. Antenatal psychological distress was associated with maternal childhood trauma, antenatal depression, and PTSD, and inversely associated with partner support. No association was observed between antenatal maternal psychological distress and preterm birth or early developmental outcomes, but antenatal maternal psychological distress was associated with a smaller head circumference at birth (coefficient=-0.30, 95% CI: -0.49; -0.10).

CONCLUSION

Antenatal maternal psychological distress is common in LMIC settings and was found to be associated with key psychosocial measures during pregnancy, as well as with adverse birth outcomes, in our study population. These associations highlight the potential value of screening for antenatal maternal psychological distress as well as of developing targeted interventions.

Neurodevelopment of HIV-exposed uninfected children in South Africa: outcomes from an observational birth cohort study

BACKGROUND

HIV infection is known to cause developmental delay, but the effects of HIV exposure without infection during pregnancy on child development are unclear. We compared the neurodevelopmental outcomes of HIV-exposed uninfected and HIV-unexposed children during their first 2 years of life.

METHODS

Pregnant women (>18 years of age) at 20-28 weeks' gestation were enrolled into the Drakenstein Child Health cohort study while attending routine antenatal appointments at one of two peri-urban community-based clinics in Paarl, South Africa. Livebirths born to enrolled women during follow-up were included in the birth cohort. Mothers and infants received antenatal and postnatal HIV testing and antiretroviral therapy per local guidelines. Developmental assessments on the Bayley Scales of Infant and Toddler Development, third edition (BSID-III), were done in a subgroup of infants at 6 months of age, and in the full cohort at 24 months of age, with assessors masked to HIV exposure status. Mean raw scores and the proportions of children categorised as having a delay (scores <-2 SDs from the reference mean) on BSID-III were compared between HIV-exposed uninfected and HIV-unexposed children.

FINDINGS

1225 women were enrolled between March 5, 2012, and March 31, 2015. Of 1143 livebirths, 1065 (93%) children were in follow-up at 6 months and 1000 (87%) at 24 months. Two children were diagnosed with HIV infection between birth and 24-month follow-up and were excluded from the analysis. BSID-III assessments were done in 260 (24%) randomly selected children (61 HIV-exposed uninfected, 199 HIV-unexposed) at 6 months and in 732 (73%) children (168 HIV-exposed uninfected, 564 HIV-unexposed) at 24 months. All HIV-exposed uninfected children were exposed to antiretrovirals (88% to maternal triple antiretroviral therapy). BSID-III outcomes did not significantly differ between HIV-exposed uninfected and HIV-unexposed children at 6 months. At 24 months, HIV-exposed uninfected children scored lower than HIV-unexposed for receptive language (adjusted mean difference -1·03 [95% CI -1·69 to -0·37]) and expressive language (-1·17 [-2·09 to -0·24]), whereas adjusted differences in cognitive (-0·45 [-1·32 to 0·43]), fine motor (0·09 [-0·49 to 0·66]), and gross motor (-0·41 [-1·09 to 0·27]) domain scores between groups were not significant. Correspondingly, the proportions of HIV-exposed uninfected children with developmental delay were higher than those of HIV-unexposed children for receptive language (adjusted odds ratio 1·96 [95% CI 1·09 to 3·52]) and expressive language (2·14 [1·11 to 4·15]).

INTERPRETATION

Uninfected children exposed to maternal HIV infection and antiretroviral therapy have increased odds of receptive and expressive language delays at 2 years of age. Further long-term work is needed to understand developmental outcomes of HIV-exposed uninfected children, especially in regions such as sub-Saharan Africa that have a high prevalence of HIV exposure among children.

Risk and protective factors for child development: An observational South African birth cohort

BACKGROUND

Approximately 250 million (43%) children under the age of 5 years in low- and middle-income countries (LMICs) are failing to meet their developmental potential. Risk factors are recognised to contribute to this loss of human potential. Expanding understanding of the risks that lead to poor outcomes and which protective factors contribute to resilience in children may be critical to improving disparities.

METHODS AND FINDINGS

The Drakenstein Child Health Study is a population-based birth cohort in the Western Cape, South Africa. Pregnant women were enrolled between 20 and 28 weeks' gestation from two community clinics from 2012 to 2015; sociodemographic and psychosocial data were collected antenatally. Mothers and children were followed through birth until 2 years of age. Developmental assessments were conducted by trained assessors blinded to background, using the Bayley-III Scales of Infant and Toddler Development (BSID-III), validated for use in South Africa, at 24 months of age. The study assessed all available children at 24 months; however, some children were not able to attend, because of loss to follow-up or unavailability of a caregiver or child at the correct age. Of 1,143 live births, 1,002 were in follow-up at 24 months, and a total of 734 children (73%) had developmental assessments, of which 354 (48.2%) were girls. This sample was characterised by low household employment (n = 183; 24.9%) and household income (n = 287; 39.1% earning <R1,000 per month), and high prevalence of maternal psychosocial risk factors including alcohol use in pregnancy (n = 95; 14.5%), smoking (n = 241; 34.7%), depression (n = 156; 23.7%), lifetime intimate partner violence (n = 310; 47.3%), and history of maternal childhood trauma (n = 228; 34.7%). A high proportion of children were categorised as delayed (defined by scoring < -1 standard deviation below the mean scaled score calculated using the BSID-III norms from a United States population) in different domains (369 [50.5%] cognition, 402 [55.6%] receptive language, 389 [55.4%] expressive language, 169 [23.2%] fine motor, and 267 [38.4%] gross motor). Four hundred five (55.3%) children had >1 domain affected, and 75 (10.2%) had delay in all domains. Bivariate and multivariable analyses revealed several factors that were associated with developmental outcomes. These included protective factors (maternal education, higher birth weight, and socioeconomic status) and risk factors (maternal anaemia in pregnancy, depression or lifetime intimate partner violence, and maternal HIV infection). Boys consistently performed worse than girls (in cognition [β = -0.74; 95% CI -1.46 to -0.03, p = 0.042], receptive language [β = -1.10; 95% CI -1.70 to -0.49, p < 0.001], expressive language [β = -1.65; 95% CI -2.46 to -0.84, p < 0.001], and fine motor [β = -0.70; 95% CI -1.20 to -0.20, p = 0.006] scales). There was evidence that child sex interacted with risk and protective factors including birth weight, maternal anaemia in pregnancy, and socioeconomic factors. Important limitations of the study include attrition of sample from birth to assessment age and missing data in some exposure areas from those assessed.

CONCLUSIONS

This study provides reliable developmental data from a sub-Saharan African setting in a well-characterised sample of mother-child dyads. Our findings highlight not only the important protective effects of maternal education, birth weight, and socioeconomic status for developmental outcomes but also sex differences in developmental outcomes and key risk and protective factors for each group.

Preliminary evaluation of a low-intensity parent training program on speech-language stimulation for children with language delay

AIM

The study assessed the outcome of a low-intensity parent training program for improving parent's language input to children with language delay.

METHOD

Nine parents and their children aged between 12 months to 24 months, exhibiting delay in language development, participated in a brief training program over three sessions. Training comprised of inputs on speech-language development, play development and speech-language stimulation strategies, supported by a manual. Effect of the training program on parent's language behaviour was evaluated through observations of parent-child interaction recorded before training and six-weeks and 10-weeks post training. Measures including, different functions served by verbalizations of parents and their nonverbal affective behaviours, were analysed.

RESULTS AND DISCUSSION

Parents' verbalizations increased significantly from baseline to the two follow-up sessions. Proportion of comments, suggestions and reflections on the child's productions increased with a concurrent decrease in the use of direct commands and questions, from baseline to post training at 10-weeks. Parents reported regular use of the manual during and after the training sessions. Post training, they identified play-based activities and provided opportunities for interactions in daily routines. Changes in the child's communication skills were also reported.

CONCLUSION

A low-intensity training program for parents, supported by a manual focusing on developmentally appropriate play and speech-language stimulation, resulted in increased verbal interaction and changes in language input to children.

Comparison of physical growth of teenage girls with low birth weight and normal weight of Isfahan in 2016 - 2017

INTRODUCTION

One of the probable risks of low birth weight (LBW) is low body growth at teenage, and most of the parents are concerned about it. This study was conducted to compare the body growth of girls at teenage in two groups.

METHODOLOGY

In this descriptive-comparative research, the body growth of 350 girls (250 students having normal birth weight (NBW) and 125 students having LBW) at the ninth grade in Isfahan, Iran, was studied. These students were chosen randomly out of 13 select schools from six districts of education in Isfahan, Iran. The data were analyzed by Independent t-test, Chi-square test, and Mann-Whitney U-test.

RESULTS

This study showed that there is a meaningful difference in weight, height, BMI, and the age of menarche. The highest weight, height, and BMI frequency (52.8 kg, 162.8 cm, and 3.31, respectively) belongs to girls having NBW compared with girls having LBW (50.6 kg, 159.3 cm and 3.36, respectively) and Independent t-test showed that weight and height average and body mass index (BMI) of girls having NBW are higher meaningfully (P < 0.001). In addition, the girls having NBW had reached the age of menarche at 12.36 ± 1.12 and 12.09 ± 1.01 at girls having LBW. Furthermore, there was a meaningful difference (P < 0.001) between the ages of menarche.

CONCLUSION

Regarding the existence, it is recommended that the children having LBW should be kept under special care. Of course, the resulted difference is not very important and concerning for the parents, but further study is needed to reach the final conclusion.

One year outcome of high-risk newborn infants discharged from the neonatal care unit of the National Maternal and Child Health Center in Cambodia

Background

In the National Maternal and Child Health Center in Cambodia, about 7,500 newborn infants are born every year. Around 10% of them are admitted to the neonatal care unit. After recovery from the acute phase that presented neonatal care unit admissions, they are discharged even if they are very low birth weight infants, but there is no official follow-up system available after discharge. This research aims to identify the prognosis of high-risk infants one year after discharge using regular telephone interviews, identifying the factors that may determine their prognosis.

Methods

When a small and sick newborn infant was admitted to and discharged from the neonatal care unit, we collected health information from medical records. After discharge, we interviewed their caretakers by telephone when the infants were one, six, and 12 months (one year) old. We used structured questionnaires on feeding, history of illness, and development of growth and gross motor skills.

Findings

Between September 2014 and April 2015, 175 infants were discharged. At one year old, 111 (63%) had survived, 12 (6.9%) had died, and 52 (30%) were lost to follow-up. Nine cases died within one month of discharge. Our data suggested low birth weight may lead to re-hospitalization. Infants vaccinated less than twice at six months old were more likely to be re-hospitalized. According to results of our telephone interview, three infants showed psychomotor retardation at one year old. Among the 50 cases lost to follow-up, 26 (52%) of these patients were discharged without permission by doctors.

Interpretation

After one year, we noted that 63% of discharged infants survived, although 30% were lost to follow-up. There was a limitation of collecting more detailed data by telephone interview than questions about survival. The follow-up for high-risk newborn infants is an important challenge in Cambodia.

Risk factors for low birth weight in hospitals of North Wello zone, Ethiopia: A case-control study

BACKGROUND

Low birth weight at birth is an important underlying contributor for neonatal and infant mortality. It accounts for nearly half of all perinatal deaths. Identifying predictors of low birth weight is the first essential step in designing appropriate management strategies. Hence, this study aimed to identify risk factors for low birth weight in hospitals of northeastern Ethiopia.

METHODS

An institution based case-control study design was conducted from 10th April to 15th December 2016. Three hundred sixty mother-infant pairs (120 low birth weight babies as cases and 240 normal birth weights as controls) were included in the study. Data were collected by face-to-face interview. Univariable and multivariable logistic regression models were computed to examine the effect of independent variables on outcome variable using SPSS 20.0. Variables with p-value <0.05 were considered statistically significant.

RESULTS

The mean (±SD) gestational age and birth weight (±SD) were 39.2 (±1.38) weeks and 2800 (±612), grams respectively. Partner's education/being illiterate (AOR: 4.09; 95% CI 1.45, 11.50), antenatal care visit at private health institutions (AOR: 0.13; 95% CI 0.02, 0.66), having history of obstetric complications (AOR: 5.70; 95% CI 2.38, 13.63), maternal weight during pregnancy (AOR: 4.04; 95% CI 1.50, 10.84) and gravidity (AOR: 0.36; 95% CI 0.18, 0.73) were significantly associated with low birth weight. Additionally, a site for water storage and water treatment were significant environmental factors.

CONCLUSION

Maternal weight during pregnancy, paternal education, previous obstetric complication and place of antenatal follow-up were associated with low birth weight. The risk factors identified in this study are preventable. Thus, nutritional counseling, health education on improvement of lifestyle and early recognition and treatment of complications are the recommended interventions.

Pre- and postnatal exposure to intimate partner violence among South African HIV-infected mothers and infant developmental functioning at 12 months of age

In rural South Africa, pregnant HIV-infected women report high rates of psychological (55%) and physical (20%) intimate partner violence (IPV). IPV increases the risk of infant developmental delays. Such delays may have negative socioemotional and cognitive outcomes throughout the lifespan. This paper assesses the relationship between IPV and infant development in rural South Africa. The present investigation was a cross-sectional add-on follow-up designed retrospectively. A randomly selected sub-sample of mothers from the main randomized controlled trial (n = 72) were asked to participate with their infants at 12 months of age; all women invited agreed to participate. Women were 18.35 ± 5.47 weeks pregnant; demographics, HIV disclosure status, and pre- and postnatal IPV measured via the Conflict Tactics Scale during pregnancy at baseline and 12 months post-partum were assessed. Infant HIV serostatus and developmental functioning at 12 months of age were assessed. Women were a mean age of 29 ± 2 years. One third had completed at least 12 years of education and had a monthly income of ~ US$76. At 12 months post-partum, 6% of infants tested HIV seropositive. Postnatal physical IPV was associated with delays in cognitive and receptive language development p < 0.05, but only in unadjusted analyses. This study identified an association between early IPV exposure and infant cognitive and receptive communication delays. Given the small sample size, findings support replication. Longitudinal studies are needed to confirm temporal order and identify appropriate timing for interventions in HIV-exposed infants.

A retrospective study of neonatal case management and outcomes in rural Rwanda post implementation of a national neonatal care package for sick and small infants

Background

Despite worldwide efforts to reduce neonatal mortality, 44% of under-five deaths occur in the first 28 days of life. The primary causes of neonatal death are preventable or treatable. This study describes the presentation, management and outcomes of hospitalized newborns admitted to the neonatal units of two rural district hospitals in Rwanda after the 2012 launch of a national neonatal protocol and standards.

Methods

We retrospectively reviewed routinely collected data for all neonates (0 to 28 days) admitted to the neonatal units at Rwinkwavu and Kirehe District Hospitals from January 1, 2013 to December 31, 2014. Data on demographic and clinical characteristics, clinical management, and outcomes were analyzed using median and interquartile ranges for continuous data and frequencies and proportions for categorical data. Clinical management and outcome variables were stratified by birth weight and differences between low birth weight (LBW) and normal birth weight (NBW) neonates were assessed using Fisher’s exact or Wilcoxon rank-sum tests at the α = 0.05 significance level.

Results

A total of 1723 neonates were hospitalized over the two-year study period; 88.7% were admitted within the first 48 h of life, 58.4% were male, 53.8% had normal birth weight and 36.4% were born premature. Prematurity (27.8%), neonatal infection (23.6%) and asphyxia (20.2%) were the top three primary diagnoses. Per national protocol, vital signs were assessed every 3 h within the first 48 h for 82.6% of neonates (n = 965/1168) and 93.4% (n = 312/334) of neonates with infection received antibiotics. The overall mortality rate was 13.3% (n = 185/1386) and preterm/LBW infants had similar mortality rate to NBW infants (14.7 and 12.2% respectively, p = 0.131). The average length of stay in the neonatal unit was 5 days.

Conclusions

Our results suggest that it is possible to provide specialized neonatal care for both LBW and NBW high-risk neonates in resource-limited settings. Despite implementation challenges, with the introduction of the neonatal care package and defined clinical standards these most vulnerable patients showed survival rates comparable to or higher than neighboring countries.

Neurodevelopmental outcome of late preterm infants in Johannesburg, South Africa

Background

Late preterm infants, previously considered low risk, have been identified to be at risk of developmental problems in infancy and early childhood. There is limited information on the outcome of these infants in low and middle income countries.

Methods

Bayley scales of infant and toddler development, version III, were done on a group of late preterm infants in Johannesburg, South Africa. The mean composite cognitive, language and motor sub-scales were compared to those obtained from a group of typically developed control infants. Infants were considered to be “at risk” if the composite subscale score was below 85 and “disabled” if the composite subscale score was below 70. Infants identified with cerebral palsy were also reported.

Results

56 of 73 (76.7%) late preterm infants enrolled in the study had at least one Bayley assessment at a mean age of 16.5 months (95% CI 15.2–17.6). The mean birth weight was 1.9 kg (95%CI 1.8–2.0) and mean gestational age 33.0 weeks (95% CI 32.56–33.51). There was no difference in the mean cognitive subscales between late preterm infants and controls (95.4 9, 95% CI 91.2–99.5 vs 91.9.95% CI 87.7–96.0). There was similarly no difference in mean language subscales (94.5, 95% CI 91.3–97.7 vs 95.9, 95% CI 92.9–99.0) or motor subscales (96.2, 95% CI 91.8–100.7 vs 97.6, 95% CI 94.7–100.5). There were four late preterm infants who were classified as disabled, two of whom had cerebral palsy. None of the control group was disabled.

Conclusions

This study demonstrates that overall developmental outcome, as assessed by the Bayley scales of infant and toddler development, was not different between late preterm infants and a group of normal controls. However, 7.1% of the late preterm infants, had evidence of developmental disability. Thus late preterm infants in low and middle income countries require long term follow up to monitor developmental outcome. In a resource limited setting, this may best be achieved by including a parental screening questionnaire, such as the Ages and Stages Questionnaire, in the routine well baby clinic visits.

Long-term cognitive outcome of very low birth-weight Saudi preterm infants at the corrected age of 24-36 months

Objectives:

To assess infants’ cognitive function at the corrected age of 24-36 months, and to identify factors associated with adverse outcome and examine the correlation between Bayley Infants Neurodevelopmental Screener (BINS) score and Gesell Schedule of Child Development (GSCD).

Methods:

This retrospective study was performed on Saudi very low birth-weight (VLBW) infants born in King Khalid University Hospital, Riyadh, Saudi Arabia between 1997 and 2014 by the use of BINS as screening test and GSCD as definitive test.

Results:

Of 561 enrolled infants, 367 (65.4%) continued to follow-up. Three-hundred and fifteen infants (85.6%) had a normal cognitive function. In addition to lower birth weight (beta = -0.003) (p<0.001), male gender (OR =3.9) (p=0.001)and cerebral palsy (OR =33.9) (p<0.001) were the strongest factors associated with poor cognitive outcome. Approximately 75.4% of infants with normal BINS score had normal cognitive function and 7.6% of total infants had sever cognitive impairment.

Conclusion:

The majority of VLBW infants in our center have normal cognitive function at the corrected age of 24-36 months. Male gender, lower birth weight, and cerebral palsy are major predictors of poor outcome. The BINS scores were correlated with GSCD as a valid predictor for future developmental outcome.

Neuromotor Development of Children Aged 6 and 7 Years Born before the 30th Week Gestation

Introduction

The aim of this study was to evaluate and compare the level of neuromotor function and somatic development in 6- and 7-year-old children born before the 30th week gestation with that in full-term children at the same age, as well as the correlation between prematurity and motor development.

Material and Methods

The study group consisted of prematurely born 40 children. Their mean gestational age at birth was 27.8 ± 1.6 weeks (range 24–30 weeks). The control group consisted of 40 healthy children born with normal birth weight (>2500 g). The neuromotor function was assessed using Touwen neurological examination criteria. During the examination, the attention was focused on the hand preference, laterality, synkinesis, and asymmetry. In addition, children's weight, height, and BMI index were measured.

Results

Premature children showed much worse results than full-term ones in hand function (p < 0,001). They obtained the best results in paper tearing while crossing the body midline turned out to be the most difficult. Considering the quality of walking, the biggest difficulty for the premature children was to walk backwards along the straight line while during normal walking they showed the best results. The results for the muscle tone subcategory in the study group were also significantly worse than those in control group (p < 0,001), as well as the total outcome for the movement coordination and diadochokinesis subcategories (p < 0,001).

Conclusion

The nondisabled, prematurely born children have significantly lower average outcomes regarding hand function, quality of walking, muscle tone, coordination, and diadochokinesis at age of six to seven, compared to the full-term peers.

The birthweight toll of mining pollution: evidence from the most contaminated mine site in the Andean region

OBJECTIVE

To assess the effect of mining pollution on birthweight.

DESIGN

A retrospective before-and-after study with an untreated comparison group.

SETTING

La Oroya, a mining town in the Peruvian Andes, considered the most contaminated town in the Andean region.

POPULATION

All pregnant women who delivered in the social security healthcare system in years 2005, 2006, 2008 and 2009. A total of 214 983 births records were used, 957 from La Oroya and 214 026 from the rest of the country.

METHODS

A difference-in-difference estimation is used to assess the effect of mining pollution on birthweight before and after two business policy changes: a partial environmental improvement and a subsequent closure of smelter operations in La Oroya. Birthweight was compared with a group not affected by the environmental changes in La Oroya.

MAIN OUTCOME MEASURES

Birthweight in grams.

RESULTS

A steep reduction in mining pollution due to the closure of smelter operations in La Oroya showed an increased birthweight of 71.6 g after controlling for socio-economic and medical characteristics. None of the environmental improvements prior to the closure had a statistically significant effect on birthweight.

CONCLUSIONS

Mining pollution in La Oroya had a negative impact on birthweight. Partial environmental improvements were not enough to improve birthweight. Only after the closure of all mining and smelter operations in La Oroya was a significant gain in birthweight shown.

TWEETABLE ABSTRACT

The closure of the most contaminated mine site in the Andean region increased birthweight by 72 g.

Neurodevelopmental assessment of HIV-exposed uninfected and early-treated HIV-infected children: study protocol

Objective

Sub-Saharan Africa has the highest prevalence of children at risk of not achieving their developmental potential, attributable largely to the human immunodeficiency virus (HIV) pandemic coupled with negative environmental factors. Childhood developmental stimulation programmes can mitigate adverse outcomes.

Methods

Neonates testing HIV positive at birth will be initiated on antiretroviral treatment (ART) and receive an age-appropriate stimulation program, updated at 3 monthly intervals through the first year of life. Neurodevelopment at 12 months of age will be assessed using the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III). Outcomes will be compared with HIV-infected and HIV-exposed uninfected children (HEU) not having received the stimulatory intervention. Associations between neurodevelopmental outcomes, environmental factors, and parental stress will be investigated. The study will take place at a single site in Johannesburg, South Africa. This non-randomised controlled intervention study, with a single non-blinded comparative intervention group, aims to investigate whether an early childhood stimulation programme used in conjunction with ART initiated at birth can positively impact neurodevelopmental outcomes at 1 year of age in children infected with HIV.

Neurodevelopmental outcome in very preterm and very-low-birthweight infants born over the past decade: a meta-analytic review

AIM

The purpose of this systematic review was to provide an up-to-date global overview of the separate prevalences of motor and cognitive delays and cerebral palsy (CP) in very preterm (VPT) and very-low-birthweight (VLBW) infants.

METHOD

A comprehensive search was conducted across four databases. Cohort studies reporting the prevalence of CP and motor or cognitive outcome from 18 months corrected age until 6 years of VPT or VLBW infants born after 2006 were included. Pooled prevalences were calculated with random-effects models.

RESULTS

Thirty studies were retained, which included a total of 10 293 infants. The pooled prevalence of cognitive and motor delays, evaluated with developmental tests, was estimated at 16.9% (95% confidence interval [CI] 10.4-26.3) and 20.6% (95% CI 13.9-29.4%) respectively. Mild delays were more frequent than moderate-to-severe delays. Pooled prevalence of CP was estimated to be 6.8% (95% CI 5.5-8.4). Decreasing gestational age and birthweight resulted in higher prevalences. Lower pooled prevalences were found with the Third Edition of the Bayley Scales of Infant Development than with the Second Edition.

INTERPRETATION

Even though neonatal intensive care has improved over recent decades, there is still a wide range of neurodevelopmental disabilities resulting from VPT and VLBW births. However, pooled prevalences of CP have diminished over the years.

WHAT THIS PAPER ADDS

The Bayley Scales of Infant and Toddler Development, Third Edition reported lower pooled prevalences of motor and cognitive delays than the Second Edition. The pooled prevalence of cerebral palsy in infants born extremely preterm was reduced compared with previous meta-analyses.

Kangaroo mother care: using formative research to design an acceptable community intervention

Background

Low and middle income countries (LMICs), including India, contribute to a major proportion of low birth weight (LBW) infants globally. These infants require special care. Kangaroo Mother Care (KMC) in hospitals is a cost effective and efficacious intervention. In institutional deliveries, the duration of facility stay is often short. In LMICs, a substantial proportion of deliveries still occur at home and access to health care services is limited. In these circumstances, a pragmatic choice may be to initiate KMC at home for LBW babies. However, evidence is lacking on benefits of community-initiated KMC (cKMC). Promoting KMC at home without an understanding of its acceptability may lead to limited success.

Methods

We conducted formative research to assess the feasibility, acceptability and adoption of cKMC with the aim of designing an intervention package for a randomised controlled trial in LBW infants in Haryana, India. Qualitative methods included 40 in-depth interviews with recently delivered women and 6 focus group discussions, two each with fathers and grandfathers, grandmothers, and community health workers. A prototype intervention package to promote cKMC was developed and tested in 28 mother-infant pairs (of them, one mother had twins), using Household (HH) trials.

Results

We found that most mothers in the community recognized that babies born small required special care. In spite of not being aware of the practice of KMC, respondents felt that creating awareness of KMC benefits will promote practice. They expressed concerns about doing KMC for long periods because mothers needed rest after delivery. However, the cultural practice of recently delivered women not expected to be doing household chores and availability of other family members were identified as enablers. HH trials provided an opportunity to test the intervention package and showed high acceptability for KMC. Most mothers perceived benefits such as weight gain and increased activity in the infant.

Conclusions

Community-initiated KMC is acceptable by mothers and adoption rates are high. Formative research is essential for developing a strategy for delivery of an intervention.

Assessing retention in care after 12 months of the Pediatric Development Clinic implementation in rural Rwanda: a retrospective cohort study

Background

In Africa, a high proportion of children are at risk for developmental delay. Early interventions are known to improve outcomes, but they are not routinely available. The Rwandan Ministry of Health with Partners In Health/Inshuti Mu Buzima created the Pediatric Development Clinic (PDC) model for providing interdisciplinary developmental care for high-risk infants in rural settings. As retention for chronic care has proven challenging in many settings, this study assesses factors related to retention to care after 12 months of clinic enrollment.

Methods

This study describes a retrospective cohort of children enrolled for 12 months in the PDC program in Southern Kayonza district between April 2014–March 2015. We reviewed routinely collected data from electronic medical records and patient charts. We described patient characteristics and the proportion of patients retained, died, transferred out or lost to follow up (LTFU) at 12 months. We used Fisher’s exact test and multivariable logistic regression to identify factors associated with retention in care.

Results

228 children enrolled in PDC from 1 April 2014–31 March 2015, with prematurity/low birth weight (62.2%) and hypoxic ischemic encephalopathy (34.5%) as the most frequent referral diagnoses. 64.5% of children were retained in care and 32.5% were LTFU after 12 months. In the unadjusted analysis, we found male sex (p = 0.189), having more children at home (p = 0.027), health facility of first visit (p = 0.006), having a PDC in the nearest health facility (p = 0.136), referral in second six months of PDC operation (p = 0.006), and social support to be associated (100%, p < 0.001) with retention after 12 months. In adjusted analysis, referral in second six months of PDC operation (Odds Ratio (OR) 2.56, 95% CI 1.36, 4.80) was associated with increased retention, and being diagnosed with more complex conditions (trisomy 21, cleft lip/palate, hydrocephalus, other developmental delay) was associated with LTFU (OR 0.34, 95% CI 0.15, 0.76). As 100% of those receiving social support were retained in care, this was not able to be assessed in adjusted analysis.

Conclusions

PDC retention in care is encouraging. Provision of social assistance and decentralization of the program are major components of the delivery of services related to retention in care.

Thyroid Function in Pregnant Women With Moderate to Severe Alcohol Consumption Is Related to Infant Developmental Outcomes

INTRODUCTION

Fetal alcohol spectrum disorders (FASD) have an estimated global prevalence of 2-5% of births, but prevalence is reported to be as high as 15.5% for FASD in certain high-risk communities in South Africa. Preclinical studies demonstrate that alcohol consumption during pregnancy interferes with thyroid hormone availability and function and negatively impacts exposed offspring. Very little is currently reported on this phenomenon in humans.

METHODS

This pilot study was embedded in the Drakenstein Child Health Study, a multi-disciplinary longitudinal birth cohort study investigating the early biological and psychosocial determinants of child health in South Africa. Twenty one mothers and their children with moderate-severe prenatal alcohol exposure (PAE) and 19 mothers and their children with no alcohol exposure were investigated. Maternal exposure history and blood samples were collected in mid-pregnancy and analyzed for serum-free thyroxin (FT4), free triiodothyronine (FT3), and thyroid stimulating hormone (TSH). Children were assessed with formally measured growth parameters and development was evaluated using the Bayley III Scales of Infant and Toddler Development (BSID III) at 6 and 24 months of age.

RESULTS

While there were no significant differences in serum TSH and FT4 between groups, FT3 levels were significantly higher in mothers with moderate-severe prenatal alcohol use. In abstinent pregnant women, levels of FT4 were significantly correlated with infants' scores on cognitive measures at 6 and 24 months of age and with levels of gross motor skills at 24 months. However, in mothers with alcohol use, FT4 levels were not correlated with any cognitive or motor skills, but FT3 levels were significantly associated with scores on children's social-emotional development at 24 months of age.

DISCUSSION

Thyroid function in PAE is sufficiently disrupted to lead to alterations in serum FT3 levels. The contrast in findings between PAE and abstinent dyads in their association of maternal thyroid function and infant development further suggests that such disruption is present and may contribute to adverse neurodevelopment. Further work is needed to determine the relationship between peripheral thyroid indices during pregnancy and neurodevelopmental outcomes in the context of PAE.

Anthropometric measures at birth and early childhood are associated with neurodevelopmental outcomes among Bangladeshi children aged 2-3years

Among a cohort of children located in rural areas of Bangladesh affected by high levels of exposure to environmental metals, we investigated the associations between anthropometric measures, growth trajectory, and neurodevelopment at age 20-40months. Our study population included mothers and their children who participated in a longitudinal birth cohort study that took in place in the Pabna and Sirajdikhan areas of Bangladesh. Anthropometric measures including weight, length, and head circumference were measured at birth, age 12months, and age 20-40months. Neurodevelopment was assessed using Bayley Scales of Infant and Toddler Development Third Edition (BSID-III) multi-scale at age 20-40months. A total of 777 mother-child pairs were included. Higher anthropometric measures at 20-40months were associated with higher cognitive, language, and motor scores on BSID-III. For example, a 1-kg increment in birthweight was associated with an increase of 2.11 for cognitive score (p<0.0001), 1.63 for language score (p=0.006), and 0.89 for motor scores (p=0.03). Greater positive changes in growth parameters, or growth trajectory, between birth and 20-40months were also associated with higher BSID-III scores. These associations remained significant after adjusting for potential confounders and prenatal exposure to environmental metals. These findings suggest that even when taking into account high environmental metal exposures, prenatal and early childhood growth have strong associations with neurodevelopmental test scores in early childhood.

Health, nutrition, and development of children born preterm and low birth weight in rural Rwanda: a cross-sectional study

Background

As care for preterm and low birth weight (LBW) infants improves in resource-limited settings, more infants are surviving the neonatal period. Preterm and (LBW) infants are at high-risk of nutritional and medical comorbidities, yet little is known about their developmental outcomes in low-income countries. This study evaluated the health, nutritional, and developmental status of preterm/LBW children at ages 1–3 years in Rwanda.

Methods

Cross-sectional study of preterm/LBW infants discharged between October 2011 and October 2013 from a hospital neonatal unit in rural Rwanda. Gestational age and birth weight were gathered from hospital records to classify small for gestational age (SGA) at birth and prematurity. Children were located in the community for household assessments in November–December 2014. Caregivers reported demographics, health status, and child development using locally-adapted Ages and Stages Questionnaires (ASQ-3). Anthropometrics were measured. Bivariate associations with continuous ASQ-3 scores were conducted using Wilcoxon Rank Sum and Kruskal Wallis tests.

Results

Of 158 eligible preterm/LBW children discharged from the neonatal unit, 86 (54.4%) were alive and located for follow-up. Median birth weight was 1650 grams, median gestational age was 33 weeks, and 50.5% were SGA at birth. At the time of household interviews, median age was 22.5 months, 46.5% of children had feeding difficulties and 39.5% reported signs of anemia. 78.3% of children were stunted and 8.8% wasted. 67.4% had abnormal developmental screening. Feeding difficulties (p = 0.008), anemia symptoms (p = 0.040), microcephaly (p = 0.004), stunting (p = 0.034), SGA (p = 0.023), very LBW (p = 0.043), lower caregiver education (p = 0.001), and more children in the household (p = 0.016) were associated with lower ASQ-3 scores.

Conclusions

High levels of health, growth, and developmental abnormalities were seen in preterm/LBW children at age 1–3 years. As we achieve necessary gains in newborn survival in resource-limited settings, follow-up and early intervention services are critical for ensuring high-risk children reach their developmental potential.

Neurodevelopmental outcomes for high-risk neonates in a low-resource setting

Worldwide, most neonates who survive prematurity and serious illness reside in low-resource settings where developmental outcome data and follow-up care are limited. This study aimed to assess in Fiji, a low-resource Pacific setting, prevalence and risk factors for moderate to severe neurodevelopmental impairment (NDI) in early childhood among high-risk neonates compared with controls. Retrospective cohort study comparing long-term outcomes for high-risk neonatal intensive care unit patients (n=149) compared with matched term, normal birth weight neonates (n=147) discharged from Colonial War Memorial Hospital between November 2008 and April 2010. NDI was defined as one or more of cerebral palsy, moderate to severe hearing or visual impairment, or global developmental delay using Bayley Scales of Infant and Toddler Development Third Edition (ie, score <70 in ≥1 of cognitive, language or motor domains). At median (IQR) age 36.1 (28.3, 38.0) months, prevalence of moderate to severe NDI % (95% CI, n) in high-risk and control groups was 12 (5 to 17, n=13) and 5 (2 to 12, n=5), respectively, an increased risk ratio (95% CI) of 2.7 (0.8 to 8.9). Median gestational age (weeks (median, IQR)) in the high-risk group was 37.5 (34-40) weeks. Among high-risk neonates, gestational age, birth weight, asphyxia, meningitis and/or respiratory distress were significantly associated with risk of NDI. Prevalence of NDI was high among this predominantly term high-risk neonatal cohort compared with controls. Results, including identified risk factors, inform efforts to strengthen quality of care and models of follow-up for high-risk neonates in this low-resource setting.

Use of the Bayley Scales of Infant and Toddler Development, Third Edition, to Assess Developmental Outcome in Infants and Young Children in an Urban Setting in South Africa

Background

The Bayley Scales of Infant and Toddler Development (III) is a tool developed in a Western setting.

Aim

To evaluate the development of a group of inner city children in South Africa with no neonatal risk factors using the Bayley Scales of Infant and Toddler Development (III), to determine an appropriate cut-off to define developmental delay, and to establish variation in scores done in the same children before and after one year of age.

Methods

Cohort follow-up study.

Results

74 children had at least one Bayley III assessment at a mean age of 19.4 months (95% CI 18.4 to 20.4). The mean composite cognitive score was 92.2 (95% CI 89.4 to 95.0), the mean composite language score was 94.8 (95% CI 92.5 to 97.1), and mean composite motor score was 98.8 (95% CI 96.8 to 101.0). No child had developmental delay using a cut-off score of 70. In paired assessments above and below one year of age, the cognitive score remained unchanged, the language score decreased significantly (p = 0.001), and motor score increased significantly (p = 0.004) between the two ages.

Conclusion

The Bayley Scales of Infant and Toddler Development (III) is a suitable tool for assessing development in urban children in southern Africa.

A retrospective review of the Pediatric Development Clinic implementation: a model to improve medical, nutritional and developmental outcomes of at-risk under-five children in rural Rwanda

Background

As more high-risk newborns survive the neonatal period, they remain at significant medical, nutritional, and developmental risk. However, no follow-up system for early intervention exists in most developing countries. In 2014, a novel Pediatric Development Clinic (PDC) was implemented to provide comprehensive follow-up to at-risk under-five children, led by nurses and social workers in a district hospital and surrounding health centers in rural Rwanda.

Methods

At each PDC visit, children undergo clinical/nutritional assessment and caregivers participate in counseling sessions. Social assessments identify families needing additional social support. Developmental assessment is completed using Ages and Stages Questionnaires. A retrospective medical record review was conducted to evaluate the first 24 months of PDC implementation for patients enrolled between April 2014–December 2015 in rural Rwanda. Demographic and clinical characteristics of patients and their caregivers were described using frequencies and proportions. Completion of different core components of PDC visits were compared overtime using Fisher’s Exact test and p-values calculated using trend analysis.

Results

426 patients enrolled at 5 PDC sites. 54% were female, 44% were neonates and 35% were under 6 months at enrollment. Most frequent referral reasons were prematurity/low birth weight (63%) and hypoxic-ischemic encephalopathy (34%). In 24 months, 2787 PDC visits were conducted. Nurses consistently completed anthropometric measurements (age, weight, height) at all visits. Some visit components were inconsistently recorded, including adjusted age (p = 0.003), interval growth, danger sign assessment, and feeding difficulties (p < 0.001). Completion of other visit components, such as child development counseling and play/stimulation activities, were low but improved with time (p < 0.001).

Conclusions

It is feasible to implement PDCs with non-specialized providers in rural settings as we were able to enroll a diverse group of high-risk infants. We are seeing an improvement in services offered at PDCs over time and continuous quality improvement efforts are underway to strengthen current gaps. Future studies looking at the outcomes of the children benefiting from the PDC program are underway.

Maternal posttraumatic stress disorder and infant developmental outcomes in a South African birth cohort study

OBJECTIVE

To investigate the association between maternal posttraumatic stress disorder (PTSD) and infant development in a South African birth cohort.

METHOD

Data from the Drakenstein Child Health Study were analyzed. Maternal psychopathology was assessed using self-report and clinician-administered interviews; and 6-month infant development using the Bayley III Scales of Infant Development. Linear regression analyses explored associations between predictor and outcome variables.

RESULTS

Data from 111 mothers and 112 infants (1 set of twins) were included. Most mothers (72%) reported lifetime trauma exposure; the lifetime prevalence of PTSD was 20%. Maternal PTSD was significantly associated with poorer fine motor and adaptive behavior - motor development; the latter remaining significant when adjusted for site, alcohol dependence, and infant head-circumference-for-age z score at birth.

CONCLUSION

Maternal PTSD may be associated with impaired infant neurodevelopment. Further work in low- and middle-income populations may improve early childhood development in this context. (PsycINFO Database Record

Comparative Investigation of Indicators of Growth and Behavioral Disorders in Children with Normal, Low, and Very Low Birth Weight at Pre-school Age in Isfahan during 2015

INTRODUCTION

Birth weight is one of the most important indicators of infant's health and could predict their health condition in future. This study was conducted to determine and compare indicators of growth [weight, height, and body mass index (BMI)] and behavioral disorders in children with normal, low, and very low birth weight at pre-school age.

MATERIALS AND METHODS

In this descriptive analytical study, 236 children (126 with normal weight, 100 with low birth weight, and 10 with very low birth weight) at pre-school age were investigated in three groups. Data collection tools were a two-part questionnaire including the Rutter Children Behavior Questionnaire for parents, and parents' and children's demographic characteristics questionnaire, scale, and stadiometer. Data were analyzed using descriptive statistics, variance analysis, Chi square, and Kruskal-Wallis tests.

RESULTS

The mean of weight, height, and BMI at pre-school age in three groups had a significant difference (P = 0.009) and it was lower in the group with very low birth weight than the other two groups; however, the difference between the group with normal birth weight and the group with low birth weight was not significant (P = 0.10). The mean score of behavioral disorder had no significant difference between groups (P = 0.49).

CONCLUSIONS

Results showed that children with very low birth weight grew less than the other two groups. Therefore, this group needs special attention and long-term follow-up for taking care of them to ensure better growth. It is recommended to conduct more extended studies to evaluate behavioral disorders in these children.

How do low-birthweight neonates fare 2 years after discharge from a low-technology neonatal care unit in a rural district hospital in Burundi?

OBJECTIVES

As neonatal care is being scaled up in economically poor settings, there is a need to know more on post-hospital discharge and longer-term outcomes. Of particular interest are mortality, prevalence of developmental impairments and malnutrition, all known to be worse in low-birthweight neonates (LBW, <2500 g). Getting a better handle on these parameters might justify and guide support interventions. Two years after hospital discharge, we thus assessed: mortality, developmental impairments and nutritional status of LBW children.

METHODS

Household survey of LBW neonates discharged from a neonatal special care unit in Rural Burundi between January and December 2012.

RESULTS

Of 146 LBW neonates, 23% could not be traced and 4% had died. Of the remaining 107 children (median age = 27 months), at least one developmental impairment was found in 27%, with 8% having at least five impairments. Main impairments included delays in motor development (17%) and in learning and speech (12%). Compared to LBW children (n = 100), very-low-birthweight (VLBW, <1500 g, n = 7) children had a significantly higher risk of impairments (intellectual - P = 0.001), needing constant supervision and creating a household burden (P = 0.009). Of all children (n-107), 18% were acutely malnourished, with a 3½ times higher risk in VLBWs (P = 0.02).

CONCLUSIONS

Reassuringly, most children were thriving 2 years after discharge. However, malnutrition was prevalent and one in three manifested developmental impairments (particularly VLBWs) echoing the need for support programmes. A considerable proportion of children could not be traced, and this emphasises the need for follow-up systems post-discharge.

[Longitudinal evaluation of functional neurodevelopmental diagnosis according to the Munich Method in preterm infants]

OBJECTIVE

The natural acquisition of motor skills during childhood can be affected by a gestational age of less than 40 weeks. Early detection favors timely management and prevention of sequelae, therefore, having a reliable tool for evaluating motor development in preterm children is necessary. A useful tool for this purpose is the Munich functional developmental diagnosis, which evaluates development ontogeny during the first year of life in children. This paper aims at analyzing the correlation between the Munich functional developmental diagnosis and the clinical assessment to determine the usefulness of such method in preterm patients.

METHODS

Descriptive and retrospective study, in which the clinical records of 165 children with corrected age between 0 and 12 months of age and a history of gestational age of less than 40 weeks were evaluated. The method was used with all the children during a follow-up visit at Instituto Materno Infantil in Bogotá, between 2008 and 2011.

RESULTS

A high correlation between corrected age and motor age obtained was found according to the Munich functional developmental diagnosis method.

CONCLUSIONS

The high correlation between each milestone evaluated and the corrected age of preterm infants makes the Munich method useful for the evaluation of motor development since this is a short test, easy to apply.

Neurodevelopmental Outcome of Extremely Low Birth Weight Children at Corrected Age of Two Years

OBJECTIVE

To assess the neurodevelopmental, cognitive and behavioral function of extremely low birth weight babies (ELBW) till corrected age of two years.

METHODS

79 ELBW babies were enrolled and followed at 1 year (n=50), 18 months (n=47) and 2 years (n=36). Adverse composite outcome was defined as death or moderate-to-severe neurodevelopmental impairment (defined as either cerebral palsy or DQ score <70 or deafness or blindness).

RESULTS

At 1 year, 24% were neurologically abnormal. At 18 months, average score (>85) was seen in 25 (54%) children in motor and 8 (17%) in mental development. Abnormal behavioral score (?12) was seen in 89% children. Adverse composite outcome was present in 28 (35.4%) babies.

CONCLUSIONS

ELBW neonates are at a high risk of neurodevelopmental and behavioral impairment.
