Family configuration and family size

In a sample of 61,829 US families, the probability of having an additional child is higher in those families with all the children the same sex as compared to those families with children of both sexes. Data are from families of American high school students who took the National Merit Scholarship Qualifying test in 1965. All families with 3 or 4 children were selected. Families with only boys were more likely to have an additional child than families with all girls. Less than 1% of the variance in family size is explained by family configuration. Although the sample size makes these results unequivocal for the population involved, the population is clearly biased in favor of white middle class families.     

Familial Accumulation of Social Anxiety Symptoms and Maladaptive Emotion Regulation

BackgroundSocial anxiety is thought to be strongly related to maladaptive emotion regulation (ER). As social anxiety symptoms accumulate in families, we hypothesize that maladaptive ER is also more prevalent in families with anxious children. Thus, we analyze differences in emotion regulation of both child and mother in relation to social anxiety, as well as both their ER strategies in dealing with anxiety. Further, a positive relation between child and maternal ER strategies is assumed.MethodChildren (aged 9 to 13 years) with social, anxiety disorder (SAD; n = 25) and healthy controls (HC, n = 26) as well as their mothers completed several measures of social anxiety and trait ER strategies towards anxiety. As ER of children is still in development, age is considered as covariate.ResultsSAD children and their mothers reported more maladaptive ER strategies than HC dyads. Maternal maladaptive ER was related negatively to child adaptive ER which was further moderated by the child’s age.DiscussionMaladaptive ER strategies seem to contribute to the exacerbation of social anxiety in both mother and child. Mothers reporting maladaptive ER may have difficulties supporting their child in coping with social anxiety while simultaneously also experiencing heightened levels of anxiety. Deeper understanding of interactional processes between mothers and children during development can assist the comprehension of factors maintaining SAD. Implications for future research and possible consequences for interventions are discussed.     

Child–Companion Animal Attachment Bonds in Single and Two-Parent Families

ABSTRACT

This study addressed the issue of whether children who potentially have reduced access to parental resources have a stronger attachment bond with a dog, compared with children who have greater access. The study compared children in single-parent families with those in two-parent families on level of attachment to their family dog. Parents judged children's level of attachment to dogs by completing the Companion Animal Bonding Scale. The children's ages ranged between three and twelve years. Overall, children in single-parent families did show significantly higher levels of attachment to dogs than children in two-parent families. A comparison of attachment to dogs across family type showed that children in the early childhood stage in single-parent families had significantly higher levels of bonding with dogs than children in the early childhood stage in two-parent families. For the middle childhood stage there was no significant difference between family type and attachment to dogs. Comparisons within family type showed mixed results, and there were no significant gender differences in attachment levels across family type. Findings are discussed in light of attachment theory, family systems theory and implications for child development.     

Use of Insecticide-Treated School Uniforms for Prevention of Dengue in Schoolchildren: A Cost-Effectiveness Analysis

BackgroundDengue-related illness is a leading cause of hospitalization and death, particularly among children. Practical, acceptable and affordable measures are urgently needed to protect this age group. Schools where children spend most of their day is proposed as an ideal setting to implement preventive strategies against day-biting Aedes mosquitoes. The use of insecticide-treated school uniforms is a promising strategy currently under investigation.MethodsUsing a decision-analytic model, we evaluated the cost-effectiveness of the use of insecticide-treated school uniforms for prevention of dengue, compared with a “do-nothing” alternative, in schoolchildren from the societal perspective. We explored how the potential economic value of the intervention varied under various scenarios of intervention effectiveness and cost, as well as dengue infection risk in school-aged children, using data specific to Thailand.ResultsAt an average dengue incidence rate of 5.8% per year in school-aged children, the intervention was cost-effective (ICER≤$16,440) in a variety of scenarios when the intervention cost per child was $5.3 or less and the intervention effectiveness was 50% or higher. In fact, the intervention was cost saving (ICER<0) in all scenarios in which the intervention cost per child was $2.9 or less per year and the intervention effectiveness was 50% or higher. The results suggested that this intervention would be of no interest to Thai policy makers when the intervention cost per child was $10.6 or higher per year regardless of intervention effectiveness (ICER>$16,440).ConclusionsOur results present the potential economic value of the use of insecticide-treated uniforms for prevention of dengue in schoolchildren in a typical dengue endemic setting and highlight the urgent need for additional research on this intervention.     

Opportunity gaps in out-of-school learning: How structural and process features of programs relate to race and socioeconomic status

Abstract

Out-of-school learning programs can be a context for positive development and learning for children and youth. However, research points to potential racial and socioeconomic disparities, or opportunity gaps, in this context. In this study, we use survey and video data from 106 staff across 30 out-of-school programs to examine how three features, staff, activities, and adult–child interactions, differ based on the racial and socioeconomic makeup of programs. We find that staff at programs serving children from low-income families on average have less experience and education. Also, programs serving children from African American and low-income families tend to offer more academic-focused activities. Finally, we found no differences in adult–child interaction quality across programs in the sample. Our findings suggest that a racial and socioeconomic opportunity gap may exist in the out-of-school context. This has implications for educational equity and the positive development of children that participate in this context.     

The extent of protective footwear use among school-age rural children at high risk for podoconiosis and socio-economic correlates: A household cross-sectional survey in Southern Ethiopia

BackgroundPodoconiosis is preventable if genetically susceptible people wear shoes starting from an early age and do so consistently. However, lack of routine use of footwear is one of the major risk factors for podoconiosis and several other foot-related Neglected Tropical Diseases (NTDs). This study is aimed at describing the extent of footwear use among school-age rural children susceptible to the disease and investigating associated socioeconomic factors.MethodsCross sectional surveys were conducted in 330 randomly selected households in Wolaita zone, southern Ethiopia. A household head and a child aged between 9 and 15 years were recruited from each household. Household heads provided socioeconomic data while children were asked about their footwear ownership and footwear use.ResultsNearly half (49.5%) of the children reported either walking barefoot or wearing under-protective footwear in a range of situations. Girls, older children, those in higher school grades, who belonged to families with higher socio-economic status, and those who owned a larger number of pairs of footwear reported more protective use of footwear. The linear regression model constituting the adequacy of footwear ownership and interaction term (i.e. family socioeconomic status by adequacy of footwear ownership) variables explained 30% of variance in the protective use of footwear (AR² = 0.307). The interaction effect of adequate ownership of footwear and family socioeconomic status consistently predicted the protective use of footwear among children (β = -0.175, p<0.01) though the main effect of adequacy of footwear ownership was stronger (β = 0.507, p<0.001).ConclusionIncreased adoption of protective footwear is needed to effectively prevent school-age children living in endemic areas from developing podoconiosis and other neglected tropical diseases. Interventions aimed to improve the protective footwear use should consider approaches that also increase the socio-economic capacity of families in podoconiosis endemic communities.     

Preventing injuries in children: cluster randomised controlled trial in primary care

ObjectiveTo assess the effectiveness of safety advice at child health surveillance consultations, provision of low cost safety equipment to families receiving means tested state benefits, home safety checks, and first aid training on frequency and severity of unintentional injuries in children at home.DesignCluster randomised controlled trial.Setting36 general practices in Nottingham.SubjectsAll children aged 3-12 months registered with participating practices.InterventionsA package of safety advice at child health surveillance consultations at 6-9, 12-15, and 18-24 months; provision of low cost safety equipment to families on means tested state benefits; and home safety checks and first aid training by health visitors.ResultsAt baseline, both groups had similar risk factors for injury, sociodemographic characteristics, safety practices, possession and use of safety equipment, knowledge and confidence in dealing with first aid, and perceptions of risk. No significant difference was found in frequency of at least one medically attended injury (odds ratio 0.97, 95% confidence interval 0.72 to 1.30), at least one attendance at an accident and emergency department for injury (1.02, 0.76 to 1.37), at least one primary care attendance for injury (0.75, 0.48 to 1.17), or at least one hospital admission for injury (0.69, 0.42 to 1.12). No significant difference in the secondary outcome measures was found between the intervention and control groups. ConclusionsThe intervention package was not effective in reducing the frequency of minor unintentional injuries in children at home, and larger trials are required to assess the effect on more severe injuries.

Key messages

• A package of activities for preventing injuries, as suggested by the Health of the Nation, delivered to families with children aged under 3 in primary care did not reduce the frequency of minor injuries
• The findings were consistent with a reduction in the frequency of more severe injuries, and larger primary care based studies are required to test this hypothesis
• The effectiveness of each of the interventions, delivered singly, is not known

     

Puerperal morbidity: A neglected area of maternal health in Sri Lanka

Abstract

Data on women with at least two children are used to examine how the breastfeeding experience with the first child affects whether subsequent children are breastfed. Our results indicate that women most often repeat with later children the feeding decision they made with their first child. That is, those who breastfed their first child are very likely to breastfeed a later child and those who did not breastfeed their firstborn are unlikely to breastfeed a later‐bom. Among those who did not breastfeed their first child, education beyond high school increases the likelihood that they will switch to breastfeeding with a later‐born. Those who breastfed their first child are less likely to breastfeed a later‐born if the first breastfeeding experience was of short duration or was perceived to be unsuccessful or unsatisfactory or if the woman had not gone beyond high school or received anesthesia at the later birth. Hence, educational differences are greater at higher parities than at first parity.     

Services d’éducation préscolaire et comportements agressifs : un rôle de prévention pour les familles vulnérables

Context

Physical violence is a significant problem in health terms and for society as a whole. Many studies have shown that socio-economic indicators such as poverty and poor parental educational attainment are associated with an increased risk of difficulties in social adjustment of the child. The hypothesis of this study was that the pre-school educational services (PES) could help to prevent the development of physical aggression (PA) in the children of vulnerable families, and that this would depend on the age at which the child first had access to the service.

Methods

Identification of children presenting with a pattern of increased PA between 17 and 60 months of age, taken from a representative sample of children born in Quebec (N = 1691). We took into consideration the educational level of the mother and the age at which the child started to receive PES. We examined the association of these factors with the PA group to which the child belonged, while controlling against several other family characteristics which are associated with PES and PA.

Results

The children of mothers with a low level of educational attainment (no secondary school qualification) were less likely to have received PES than the others. Those who had received such attention had a considerably reduced risk of displaying a behaviour pattern of increased PA. The results of multiple logistic regression analysis revealed that the PES reduced the risk of high PA, especially if the child was exposed to the service before the age of 9 months (d = ?0.62; SD = 0.24; 95% CI: ?1.09 to ?0.16; odds ratio = 0.20; 95% CI: 0.05–0.9). Children whose mothers had obtained a secondary school diploma were at reduced risk of high PA. For them, the PES did not represent an additional protective factor.

Interpretation

PES directed towards children of poorly educated mothers might reduce considerably the risk of chronic physical aggression, especially if initiated soon after birth. As those children who aremost likely to benefit from PES are the least likely to receive it, it is necessary to put special measures in place to direct this sort of service towards at risk families.     

A family-based approach to preventing excessive weight gain

Objective: Preventing weight gain in adults and excessive weight gain in children is a high priority. We evaluated the ability of a family‐based program aimed at increasing steps and cereal consumption (for breakfast and snacks) to reduce weight gain in children and adults. Research Methods and Procedures: Families (n = 105) with at least one 8‐ to 12‐year‐old child who was at‐risk‐for‐overweight or overweight (designated as the target child) were recruited for the study. Eighty‐two families were randomly assigned to receive the family‐based intervention and 23 families to the control condition. The 13‐week intervention consisted of specific increases in daily steps (an additional 2000 steps/d) and consumption of 2 servings/d of ready‐to‐eat cereal. Results: The intervention was successful in increasing walking (steps) and cereal consumption. The intervention had positive, significant effects on percentage BMI‐for‐age and percentage body fat for target children and weight, BMI, and percentage body fat for parents. On further analysis, the positive effects of the intervention were seen largely in target girls and moms, rather than in target boys and dads. Discussion: This family‐based weight gain prevention program based on small changes holds promise for reducing excessive weight gain in families and especially in growing overweight children.     

Reproductive patterns and thalassaemia major

This study investigated the effect of the diagnosis of transfusion-dependent homozygous beta-thalassemia on subsequent parental reproductive patterns in 44 families in New South Wales. The results indicate a shift over time from parental risk-taking (either consciously or in ignorance of the implications of the diagnosis) to premature curtailment of reproduction to the likelihood of attaining birth expectations through antenatal diagnosis. 67% of families with both of their 1st 2 children affected by thalassemia major had additional children, compared with 38% of those where the 1st child was affected and the 2nd child was unaffected and 37% of families where the 1st child was unaffected and the 2nd child was affected. Overall, 48% of mothers of children with thalassemia major had as many children as they had expected at the time of marriage, 13% had more, and 39% had fewer children. The mothers of older children were less likely to have had the planned number of births than those of children born more recently. The value of antenatal diagnosis to couples at risk of thalassemia appears to have been to enable them to meet or almost meet their birth expectations.     

Association between Spouse/Child Separation and Migration-Related Stress among a Random Sample of Rural-to-Urban Migrants in Wuhan,China

BackgroundMillions of people move from rural areas to urban areas in China to pursue new opportunities while leaving their spouses and children at rural homes. Little is known about the impact of migration-related separation on mental health of these rural migrants in urban China.MethodsSurvey data from a random sample of rural-to-urban migrants (n = 1113, aged 18–45) from Wuhan were analyzed. The Domestic Migration Stress Questionnaire (DMSQ), an instrument with four subconstructs, was used to measure migration-related stress. The relationship between spouse/child separation and stress was assessed using survey estimation methods to account for the multi-level sampling design.Results16.46% of couples were separated from their spouses (spouse-separation only), 25.81% of parents were separated from their children (child separation only). Among the participants who married and had children, 5.97% were separated from both their spouses and children (double separation). Spouse-separation only and double separation did not scored significantly higher on DMSQ than those with no separation. Compared to parents without child separation, parents with child separation scored significantly higher on DMSQ (mean score = 2.88, 95% CI: [2.81, 2.95] vs. 2.60 [2.53, 2.67], p < .05). Stratified analysis by separation type and by gender indicated that the association was stronger for child-separation only and for female participants.ConclusionChild-separation is an important source of migration-related stress, and the effect is particularly strong for migrant women. Public policies and intervention programs should consider these factors to encourage and facilitate the co-migration of parents with their children to mitigate migration-related stress.     

Expectation versus Reality: The Impact of Utility on Emotional Outcomes after Returning Individualized Genetic Research Results in Pediatric Rare Disease Research,a Qualitative Interview Study

PurposeMuch information on parental perspectives on the return of individual research results (IRR) in pediatric genomic research is based on hypothetical rather than actual IRR. Our aim was to understand how the expected utility to parents who received IRR on their child from a genetic research study compared to the actual utility of the IRR received.MethodsWe conducted individual telephone interviews with parents who received IRR on their child through participation in the Manton Center for Orphan Disease Research Gene Discovery Core (GDC) at Boston Children’s Hospital (BCH).ResultsFive themes emerged around the utility that parents expected and actually received from IRR: predictability, management, family planning, finding answers, and helping science and/or families. Parents expressing negative or mixed emotions after IRR return were those who did not receive the utility they expected from the IRR. Conversely, parents who expressed positive emotions were those who received as much or greater utility than expected.ConclusionsDiscrepancies between expected and actual utility of IRR affect the experiences of parents and families enrolled in genetic research studies. An informed consent process that fosters realistic expectations between researchers and participants may help to minimize any negative impact on parents and families.     

A Pet for the Children: Factors Related to Family Pet Ownership

ABSTRACT

The demographic variables related to pet ownership in New Zealand families of 8–12 -year-olds were investigated. Questionnaire surveys were used to establish data from 312 families of primary school children. Family composition, reasons for pet acquisition, and the advantages and disadvantages of pets were also examined. Almost 90% of families owned at least one pet, and over half of these families included a child who was the sole owner of a pet. Parental employment level, living locality, and sibling status (number and position) were related to pet ownership. Parents acquired pets for their children mainly to teach responsibility and care, or because their child had asked for the pet, and these reasons were related to sibling status. Perceived advantages of pet ownership included teaching responsibility and care, love, respect and affection, and companionship. Over half the sample claimed no disadvantages of pet ownership. The most common disadvantages were finding holiday care, the time and work involved in pet care, and the mess caused by animals. Implications for future research include the distinction between child-owned and family-owned pets, the reasons for acquiring pets and their effect on the relationship with the pet, and comparisons of parent and child beliefs about the role of the family pet.     

The Cost of Autism Spectrum Disorders

Objective

A diagnosis of an autism spectrum disorders is usually associated with substantial lifetime costs to an individual, their family and the community. However, there remains an elusive factor in any cost-benefit analysis of ASD diagnosis, namely the cost of not obtaining a diagnosis. Given the infeasibility of estimating the costs of a population that, by its nature, is inaccessible, the current study compares expenses between families whose children received a formal ASD diagnosis immediately upon suspecting developmental atypicality and seeking advice, with families that experienced a delay between first suspicion and formal diagnosis.

Design

A register based questionnaire study covering all families with a child with ASD in Western Australia.

Participants

Families with one or more children diagnosed with an ASD, totalling 521 children diagnosed with an ASD; 317 records were able to be included in the final analysis.

Results

The median family cost of ASD was estimated to be AUD $34,900 per annum with almost 90% of the sum ($29,200) due to loss of income from employment. For each additional symptom reported, approximately $1,400 cost for the family per annum was added. While there was little direct influence on costs associated with a delay in the diagnosis, the delay was associated with a modest increase in the number of ASD symptoms, indirectly impacting the cost of ASD.

Conclusions

A delay in diagnosis was associated with an indirect increased financial burden to families. Early and appropriate access to early intervention is known to improve a child''s long-term outcomes and reduce lifetime costs to the individual, family and society. Consequently, a per symptom dollar value may assist in allocation of individualised funding amounts for interventions rather than a nominal amount allocated to all children below a certain age, regardless of symptom presentation, as is the case in Western Australia.     

鼓膜置管术对分泌性中耳炎患儿术后生活质量的影响

目的:探讨鼓膜置管术对分泌性中耳炎(SOM)患儿术后生活质量的影响,为临床治疗SOM患儿提供理论参考。方法:采用中文版本《慢性耳病调查量表》(CCES)、中耳炎儿童生活质量调查问卷(OM-6)评分和儿童行为量表(CBCL)对我院2016年1月到2019年8月收治的300例SOM患儿行鼓膜置管术前术后进行评分,比较分析鼓膜置管术对患者生活质量的影响。结果:治疗后,患儿CCES各项目分值较治疗前均明显升高(P0.05),患者OM-6调查问卷评分在听力丧失、情感障碍、身体疼痛、活动限制及家长担忧五个方面分值均明显降低,差异均有统计学意义(P0.05)。治疗后,男患儿CBCL调查在抑郁、社交退缩、多动、攻击性、分裂样及强迫性六个方面评分明显低于治疗前,差异均有统计学意义(P0.05);女患儿CBCL调查在抑郁、社交退缩、多动、攻击性及分裂强迫五个方面评分明显低于治疗前,差异均有统计学意义(P0.05)。结论:SOM患儿鼓膜置管术后临床症状和生活质量改善明显,鼓膜置管术是分泌性中耳炎患儿患儿有效的治疗措施。     

Oral microbiota of children in a school-based dental clinic

ObjectivesDental caries disproportionately affects disadvantaged subjects. This study hypothesized that there were greater caries extent and higher levels of caries-associated and anaerobic subgingival bacterial species in oral samples of Hispanic and immigrant children compared with non-Hispanic and US born children.MethodsChildren from a school-based dental clinic serving a community with a large Hispanic component were examined, and the extent of caries was recorded. Microbial samples were taken from teeth and the tongues of children. Samples were analyzed using DNA probes to 18 oral bacterial species.ResultsSeventy five children were examined. Extent of caries increased with child age in immigrant, but not in US born or Hispanic children. There were no differences in the microbiota based on ethnicity or whether the child was born in US or not. There was a higher species detection frequency from teeth than tongue samples. Levels of Streptococcus mutans and other Streptococcus spp increased with caries extent. Prevotella intermedia, Tannerella forsythia and Selenomonas spp were detected at low levels in these children.ConclusionsWe conclude that, while there was a high rate of dental caries in disadvantaged school children, there were no differences in the caries-associated microbiota, including S. mutans, based on ethnicity or immigration status. Furthermore, while anaerobic subgingival, periodontal pathogens were also detected in children, there was no difference in species detection based on ethnicity or immigration status. Increased levels of streptococci, including S. mutans, however, were detected with high caries levels. This suggested that while it is beneficial to target preventive and treatment programs to disadvantaged populations, there is likely no additional benefit to focus on subgroups within a population already at high risk for dental disease.     

Conditional cash transfer program and child mortality: A cross-sectional analysis nested within the 100 Million Brazilian Cohort

BackgroundBrazil has made great progress in reducing child mortality over the past decades, and a parcel of this achievement has been credited to the Bolsa Família program (BFP). We examined the association between being a BFP beneficiary and child mortality (1–4 years of age), also examining how this association differs by maternal race/skin color, gestational age at birth (term versus preterm), municipality income level, and index of quality of BFP management.Methods and findingsThis is a cross-sectional analysis nested within the 100 Million Brazilian Cohort, a population-based cohort primarily built from Brazil’s Unified Registry for Social Programs (Cadastro Único). We analyzed data from 6,309,366 children under 5 years of age whose families enrolled between 2006 and 2015. Through deterministic linkage with the BFP payroll datasets, and similarity linkage with the Brazilian Mortality Information System, 4,858,253 children were identified as beneficiaries (77%) and 1,451,113 (23%) were not. Our analysis consisted of a combination of kernel matching and weighted logistic regressions. After kernel matching, 5,308,989 (84.1%) children were included in the final weighted logistic analysis, with 4,107,920 (77.4%) of those being beneficiaries and 1,201,069 (22.6%) not, with a total of 14,897 linked deaths. Overall, BFP participation was associated with a reduction in child mortality (weighted odds ratio [OR] = 0.83; 95% CI: 0.79 to 0.88; p < 0.001). This association was stronger for preterm children (weighted OR = 0.78; 95% CI: 0.68 to 0.90; p < 0.001), children of Black mothers (weighted OR = 0.74; 95% CI: 0.57 to 0.97; p < 0.001), children living in municipalities in the lowest income quintile (first quintile of municipal income: weighted OR = 0.72; 95% CI: 0.62 to 0.82; p < 0.001), and municipalities with better index of BFP management (5th quintile of the Decentralized Management Index: weighted OR = 0.76; 95% CI: 0.66 to 0.88; p < 0.001). The main limitation of our methodology is that our propensity score approach does not account for possible unmeasured confounders. Furthermore, sensitivity analysis showed that loss of nameless death records before linkage may have resulted in overestimation of the associations between BFP participation and mortality, with loss of statistical significance in municipalities with greater losses of data and change in the direction of the association in municipalities with no losses.ConclusionsIn this study, we observed a significant association between BFP participation and child mortality in children aged 1–4 years and found that this association was stronger for children living in municipalities in the lowest quintile of wealth, in municipalities with better index of program management, and also in preterm children and children of Black mothers. These findings reinforce the evidence that programs like BFP, already proven effective in poverty reduction, have a great potential to improve child health and survival. Subgroup analysis revealed heterogeneous results, useful for policy improvement and better targeting of BFP.

In a cross-sectional analysis, Dandara Ramos, Nívea B. da Silva, and colleagues investigate the association between the Bolsa Família conditional cash transfer program, and mortality of children under 5 years of age.     

What Potentially Modifiable Factors are Associated With Treatment Nonadherence in Pediatric Growth Hormone Deficiency? A Quantitative Study

ObjectiveA recent systematic review reported that up to 71% of patients with growth hormone deficiency and their families are nonadherent to treatment as prescribed. Nonadherence to growth hormone treatment presents a substantial and costly problem for the patient, health care provider, and health care system. The current study uniquely investigated the potentially modifiable factors associated with treatment nonadherence in this endocrine disorder.MethodsThe cross-sectional study was conducted among 82 parent/caregivers of children with growth hormone deficiency who were receiving growth hormone treatment. Self-report questionnaires investigated parent/caregiver perceptions and experiences of their child’s condition and prescribed treatment, in addition to their perceived relationship with their health care professional. The 8-item Morisky medication adherence scale was used for the assessment of treatment adherence.ResultsSixty-two percent of parents/caregivers were found to be nonadherent to growth hormone treatment as prescribed. Illness perceptions (consequences, identity, and coherence) and treatment concerns were found to be significantly associated with treatment adherence, as was the quality of the health care professional–parent/caregiver relationship.ConclusionThe study confirmed the extent of the adherence problem evident among the pediatric growth hormone deficiency population. In addition, it presented an insight into the explanatory factors that underpin nonadherence to growth hormone treatment. Our findings can be used to inform the development of adherence-focused interventions, with the purpose of supporting patients and their families and improving the use of prescribed growth hormone treatment within endocrine clinical practice.     

Postmortem investigations and identification of multiple causes of child deaths: An analysis of findings from the Child Health and Mortality Prevention Surveillance (CHAMPS) network

BackgroundThe current burden of >5 million deaths yearly is the focus of the Sustainable Development Goal (SDG) to end preventable deaths of newborns and children under 5 years old by 2030. To accelerate progression toward this goal, data are needed that accurately quantify the leading causes of death, so that interventions can target the common causes. By adding postmortem pathology and microbiology studies to other available data, the Child Health and Mortality Prevention Surveillance (CHAMPS) network provides comprehensive evaluations of conditions leading to death, in contrast to standard methods that rely on data from medical records and verbal autopsy and report only a single underlying condition. We analyzed CHAMPS data to characterize the value of considering multiple causes of death.Methods and findingsWe examined deaths identified from December 2016 through November 2020 from 7 CHAMPS sites (in Bangladesh, Ethiopia, Kenya, Mali, Mozambique, Sierra Leone, and South Africa), including 741 neonatal, 278 infant, and 241 child <5 years deaths for which results from Determination of Cause of Death (DeCoDe) panels were complete. DeCoDe panelists included all conditions in the causal chain according to the ICD-10 guidelines and assessed if prevention or effective management of the condition would have prevented the death. We analyzed the distribution of all conditions listed as causal, including underlying, antecedent, and immediate causes of death. Among 1,232 deaths with an underlying condition determined, we found a range of 0 to 6 (mean 1.5, IQR 0 to 2) additional conditions in the causal chain leading to death. While pathology provides very helpful clues, we cannot always be certain that conditions identified led to death or occurred in an agonal stage of death. For neonates, preterm birth complications (most commonly respiratory distress syndrome) were the most common underlying condition (n = 282, 38%); among those with preterm birth complications, 256 (91%) had additional conditions in causal chains, including 184 (65%) with a different preterm birth complication, 128 (45%) with neonatal sepsis, 69 (24%) with lower respiratory infection (LRI), 60 (21%) with meningitis, and 25 (9%) with perinatal asphyxia/hypoxia. Of the 278 infant deaths, 212 (79%) had ≥1 additional cause of death (CoD) beyond the underlying cause. The 2 most common underlying conditions in infants were malnutrition and congenital birth defects; LRI and sepsis were the most common additional conditions in causal chains, each accounting for approximately half of deaths with either underlying condition. Of the 241 child deaths, 178 (75%) had ≥1 additional condition. Among 46 child deaths with malnutrition as the underlying condition, all had ≥1 other condition in the causal chain, most commonly sepsis, followed by LRI, malaria, and diarrheal disease. Including all positions in the causal chain for neonatal deaths resulted in 19-fold and 11-fold increases in attributable roles for meningitis and LRI, respectively. For infant deaths, the proportion caused by meningitis and sepsis increased by 16-fold and 11-fold, respectively; for child deaths, sepsis and LRI are increased 12-fold and 10-fold, respectively. While comprehensive CoD determinations were done for a substantial number of deaths, there is potential for bias regarding which deaths in surveillance areas underwent minimally invasive tissue sampling (MITS), potentially reducing representativeness of findings.ConclusionsIncluding conditions that appear anywhere in the causal chain, rather than considering underlying condition alone, markedly changed the proportion of deaths attributed to various diagnoses, especially LRI, sepsis, and meningitis. While CHAMPS methods cannot determine when 2 conditions cause death independently or may be synergistic, our findings suggest that considering the chain of events leading to death can better guide research and prevention priorities aimed at reducing child deaths.

In an analysis of data from the Child Health and Mortality Prevention Surveillance (CHAMPS) network, Robert Breiman, Dianna Blau, and colleagues investigate how considering all conditions in the causal chain leading to death informs the identification of deaths attributable to various diagnoses.
