RESUMO
BACKGROUND: The ambitious expansion of social health insurance in China has played a crucial role in preventing and alleviating poverty caused by illness. However, there is no government-sponsored health insurance program specifically for younger children and inequities are more pronounced in healthcare utilization, medical expenditure, and satisfaction in some households with severely ill children. This study assessed the effectiveness of child health insurance in terms of alleviating poverty caused by illness. METHODS: Data were collected from two rounds of follow-up surveys using the China Family Panel Studies 2016 and 2018 child questionnaires to investigate the relationship between child health insurance and household medical impoverishment (MI). Impoverishing health expenditure (IHE) and catastrophic health expenditure (CHE) were measured to quantify "poverty due to illness" in terms of absolute and relative poverty, respectively. Propensity score matching with the difference-in-differences (PSM-DID) method, robustness tests, and heterogeneity analysis were conducted to address endogeneity issues. RESULTS: Social health insurance for children significantly reduced household impoverishment due to illness. Under the shock of illness, the incidences of IHE and CHE were significantly lower in households with insured children. The poverty alleviation mechanism transmitted by children enrolled in social health insurance was primarily driven by hospitalization reimbursements and the proportion of out-of-pocket medical payments among the total medical expenditure for children. CONCLUSIONS: Children's possession of social health insurance significantly reduced the likelihood of household poverty due to illness. The poverty-reducing effect of social medical insurance is most significant in rural areas, low-income families, no-left-behind children, and infants. Targeted poverty alleviation strategies for marginalized groups and areas would ensure the equity and efficiency of health system reforms, contributing to the goal of universal health insurance coverage in China.

BACKGROUND: While medical costs of chickenpox have been researched, little is known about indirect costs. Understanding total costs is important for decisions about vaccination. This study estimated the value of lost productivity of adults missing work to care for children with chickenpox. RESEARCH DESIGN AND METHODS: It comprised an international literature review, online survey of 1,526 parents of children aged 1 to 11 years, and computation of indirect costs of chickenpox in the UK. The survey covered chickenpox episodes amongst respondents' children, time children took off school/nursery, and work absenteeism by parents/caregivers caring for them. RESULTS: Respondents reported on 2,283 children, of whom 52% (1185/2283) experienced chickenpox. Almost half (591/1185) missed days of school/nursery, averaging 5.6 days missed. In 260 cases of 542 adults providing data with such a child, an adult missed work to care for the child. The daily value of this lost productivity was £170. There were approximately 200,000 GP consultations for chickenpox and 625,000 births annually, suggesting annual chickenpox incidence lies between these figures. The estimated annual UK productivity loss due to chickenpox is £20 -£70 million ($25-$90 million). CONCLUSIONS: Annual value of lost productivity due to chickenpox is in range £20 to £70 million.
RESUMO
BACKGROUND: Maternal and child health outcomes are positively influenced by early intervention, and digital health (DH) tools provide the potential for a low-cost and scalable solution such as informational platforms or digital tracking tools. Despite the wide availability of DH tools out there for women from before to after pregnancy, user engagement remains low. OBJECTIVE: This study aims to explore the factors that shape women's DH adoption and sustained use across the maternal journey from preconception to postbirth, to improve user engagement with DH tools. METHODS: One-hour semistructured qualitative interviews were conducted with 44 women from before to after pregnancy (age range 21-40 years) about their experiences with DH. This study is part of a larger study on women's maternal experiences with health care and DH and focuses on the factors that affected women's DH adoption and sustained use. Interviews were audio recorded, transcribed verbatim, and analyzed using inductive thematic analysis. RESULTS: Five main themes and 10 subthemes were identified that affected women's adoption and sustained use of DH tools. These included themes on their preexisting attitudes to DH, perceived ease of use, perceived usefulness, perceived credibility, and perceived value of the tool. CONCLUSIONS: The themes that emerged were fully or partially mapped according to the Unified Theory of Acceptance and Use of Technology 2 model. The applicability of the model and the need to consider specific cultural nuances in the Asian context (such as the importance of trust and social influence) are discussed. The interaction of the 5 themes with DH adoption and sustained use are explored with different themes being relevant at various points of the DH adoption journey. The insights gained serve to inform future DH design and implementation of tools for women to optimize their DH engagement and the benefits they derive from it.

OBJECTIVE: To systematically assess the modifiable risk factors for developing otitis media with effusion (OME) in children under 12 years. METHODS: We searched Embase, MEDLINE, INAHTA database, CENTRAL, CDSR and Epistemonikos for cohort studies with ≥40 children per arm/prognostic factor, published in English from 2000 to November 2022. We assessed risk of bias using the Quality in Prognosis Studies checklist, and overall evidence quality was assessed using Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. Outcomes were analysed as risk ratio (RR), OR or Peto OR. RESULTS: Seven studies totalling 2 760 292 children were included. The evidence was very low quality. Fluid or pus discharge from ears (OR 2.1, 95% CI 1.01 to 4.35) and exposure to other children (RR 2.79, 95% CI 1.98 to 3.93) (OR 5.21, 95% CI 2.9 to 9.36) were strongly associated with development of OME. Coughs/colds ≥5 times (OR 1.91, 95% CI 1.22 to 2.99), breathing problems ≥5 times (RR 1.78, 95% CI 1.26 to 2.53) and ear infections (RR 1.95, 95% CI 1.39 to 2.72) in past year were associated with development of OME. Adenoid hypertrophy was strongly associated with development of fluctuating OME (recurrent OME) (OR 9.96, 95% CI 5.17 to 19.19). There was scare evidence for some potential modifiable risk factors, including breast feeding, household smoking, gastro-oesophageal reflux, dummy use and swimming. CONCLUSIONS: Upper respiratory tract infection, ear infection, adenoid hypertrophy and exposure to other children could be the predictors for development of OME. Further observational studies are needed to investigate other potential modifiable risk factors.
RESUMO
Introduction: The purpose of this secondary analysis, from a pilot randomized controlled trial of guided participation (GP), was to describe patterns of coparenting for mother and father dyads caring for an infant with complex congenital heart disease and to examine the influencing factors at infant age 6 months. Our theoretical framework included GP treatment, severity of neonatal illness (severity), coparenting pattern, and parent attention to infant weight gain (weight gain). Method: From transcribed interviews with 25 parent dyads at infant age 2 and 6 months, data relevant to coparenting were categorized for entry into a matrix table. These categories included family circumstances; infant health status, feeding, and sleeping; and how the parents worked in relation to each other for caregiving, the caregiving issues they were working on, and their caregiving goals. Results: The tabled data showed two coparenting patterns, collaborative and cooperative, with very little change from 2 to 6 months, and 6-month weight gain mention. We used Bayesian sensitivity network analysis to examine, at 6 months, GP effect in contrast to usual care (control group) effect and the effect of higher or lower severity on coparenting pattern and weight gain. The treatment group had greater percentage of collaborative coparenting pattern with higher severity. In contrast, the control group showed the percentage of dyads with a collaborative coparenting pattern was similar for higher and lower severity. Weight gain mention was higher with higher severity. Conclusion: Further coparenting pattern identification and study replication with a larger, diversified sample is planned.
RESUMO
OBJECTIVE: To determine the agreement between measurements of accommodative amplitude (AoA) in children using a specialised accommodative rule and measurments without it. METHODS: A total of 502 children underwent optometric examinations, including the measurement of visual acuity, objective and subjective refraction. AoA measurements were done with and without the Berens accommodative rule. The measurements of AoA were conducted monocularly using a -4 D lens. A fixation stick containing English letters equivalent to 20/30 visual acuity and a long millimetre ruler was used to measure AoA without the accommodative rule. This measurement was performed by the two trained examiners. The agreement between these methods was reported by 95% limits of agreement (LoA) and interclass correlation coefficient (ICC). RESULTS: The mean age of the participants was 11.7±1.3 years (range: 9-15 years) and 52.4% were male. The mean AoA with and without the accommodative rule was 20.02±6.02 D and 22.46±6.32 D, respectively. The 95% LoA between the two methods was -12.5 to 7.5 D, and the ICC was 0.67 (95% CI 0.63 to 0.70). The 95% LoA was narrower in higher age groups and males compared with females (18.92 vs 20.87). The 95% LoA was narrower in hyperopes (16.83 D) compared with emmetropes (18.37 D) and myopes (18.27 D). The agreement was not constant and decreased in higher values of AoA. CONCLUSION: There is a poor and non-constant agreement between the measurements of the AoA with and without the accommodative rule. The mean AoA was 2.5 D lower with using the accommodative rule.

OBJECTIVE: The COVID-19 pandemic severely interrupted the functioning of healthcare systems, negatively affecting the global provision of maternal and child health (MCH) services. This study aims to specify the effects of COVID-19 on these services in the Gauteng province (South Africa) and to put forward context-specific recommendations aimed at augmenting them and ensuring ongoing uninterrupted coverage, even and especially during pandemics. METHODS: In this quantitative study, a retrospective review of District Health Information System data routinely collected between February 2019 and March 2021 was conducted, comparing performance of the relevant indicators across the two-year span. The data were analyzed using Stata 16 statistical software (StataCorp). The two sample t-test with equal variance and the Mann-Whitney test were applied to evaluate the equality of the indicators. RESULTS: Routine MCH services were negatively impacted, with marked declines in all relevant indicators from the onset of the pandemic. There was a statistically significant decline in cervical cancer coverage and maternal postnatal visits within six days of delivery. While declines in the other critical indicators were likewise observed, they were not statistically significant. CONCLUSION: The South African response to the pandemic had negative repercussions on all MCH services in the Gauteng province. The lessons to be drawn from the pandemic experience should help to strengthen health system capacities, boost service provision, and mitigate future damage to the healthcare system.
RESUMO
The coronavirus disease 2019 (COVID-19) pandemic led to an unprecedented change in healthcare systems, including the swift roll-out of technology-enabled care services, such as remote consultations. Interventions such as nutrition assessments for children are likely to continue to be conducted remotely as part of an online consultation. This article considers nutrition screening and nutritional assessment in children in acute and primary care settings. The article also provides an overview of the development of the Paediatric Remote Malnutrition Application (Pedi-R-MAPP), designed to assist healthcare professionals to undertake a standardised, nutrition-focused assessment via remote consultation and/or in primary care settings. The aim of the Pedi-R-MAPP is to help identify children with declining nutritional status or new nutritional concerns and to recommend frequency of review based on the outcomes of the assessment.
RESUMO
Contraception, and the opportunity and ability to decide the timing, number, and spacing of one's pregnancies, is not just critical for maternal and infant health, but necessary for the attainment of basic reproductive rights. Short inter-pregnancy intervals have significant consequences for both maternal and newborn mortality, including preterm birth and maternal anemia, and they are a key cause of preventable deaths worldwide. Addressing the unmet need for contraception could have widespread implications for health equity and access. Integrating comprehensive contraceptive services into various health settings including antenatal care, postpartum care, and child immunization visits is vital. Contraceptive counseling should be holistic, and should involve shared decision-making and patient autonomy. Contraceptive counseling is particularly important in the post-pregnancy period, where loss to follow-up may be high, and for adolescents and other vulnerable populations who are often overlooked in these discussions. Addressing the unmet need for contraception requires collaboration and teamwork among healthcare professionals, particularly midwives and physicians, who have the opportunity to amplify one another's efforts, share best practices, advocate for broader contraceptive services, and strengthen training among midwifery and medical trainees. Members of FIGO and ICM have worked together to produce this joint statement, identifying priorities within contraceptive provision and underlining key collaborative strategies to address the unmet need for contraception.
RESUMO
BACKGROUND: Anaemia is one of the most common problems in HIV-infected patients associated with increased HIV progression, decreased functional capacity, survival and quality of life. For better interventions, up-to-date information concerning anaemia among HIV-infected children less than 5 years of age on antiretroviral therapy (ART) is vital. Thus, this study aims to determine the predictors of anaemia among HIV-infected children less than 5 years of age receiving ART in North-West Ethiopia. DESIGN: An institution-based retrospective follow-up study was conducted. STUDY SETTING: Amhara region Comprehensive Specialized Hospitals, North-West Ethiopia. PARTICIPANTS: In total, we examined 460 HIV-infected children less than 5 years of age who had followed highly active antiretroviral treatment from 2010 to 2020. OUTCOME MEASURES: The outcome measures were median time to detection of anaemia, the incidence and the effects of cotrimoxazole preventive therapy (CPT), ART adherence, tuberculosis (TB), WHO clinical stage and wasting on anaemia. RESULTS: The overall follow-up time was 9234 person-months of observation. The incidence density of anaemia was 8.34 per 1000 person-months of observation (95% CI 6.67 to 10.43). The cumulative survival probability of children after the last months of follow-up was 0.54. The independent predictors of anaemia were not receiving CPT (adjusted HR (AHR)=4.44; 95% CI 2.48 to 7.93), poor adherence to ART (AHR=2.46; 95% CI 1.37 to 4.42), TB (AHR=3.40; 95% CI 1.72 to 6.72), severe WHO clinical stage (AHR=3.03; 95% CI 1.40 to 6.58) and severe wasting (AHR=1.98; 95% CI 1.08 to 3.64). CONCLUSION AND RECOMMENDATION: The incidence rate of anaemia was high and it was provoked by predictors like CPT, ART adherence, TB, WHO clinical stage and wasting. Therefore, it is necessary to emphasise for these predictors.

BACKGROUND: Environmental enteric dysfunction (EED) is an asymptomatic intestinal disorder associated with growth impairment, delayed neurocognitive development, and impaired oral vaccine responses. OBJECTIVES: We set out to develop and validate a histopathologic scoring system on duodenal biopsies from a cohort study of children with growth failure in Bangladesh, Pakistan, and Zambia ("EED") with reference to biopsies from United States children with no clinically reported histologic pathology (referred to hereafter as "normal") or celiac disease. METHODS: Five gastrointestinal pathologists evaluated 745 hematoxylin and eosin slide images from 291 children with EED (mean age: 1.6 y) and 66 United States children (mean age: 6.8 y). Histomorphologic features (i.e., villus/crypt architecture, goblet cells, epithelial and lamina propria acute/chronic inflammation, Brunner's glands, Paneth cells, epithelial detachment, enterocyte injury, and foveolar metaplasia) were used to score each histopathologic slide. Generalized estimating equations were used to determine differences between EED, normal, and celiac disease, and receiver operating characteristic curves were used to assess predictive value. RESULTS: Biopsies from the duodenal bulb showed higher intramucosal Brunner's gland scores and lower intraepithelial lymphocyte scores than from the second or third parts of the duodenum (D2/3), so only D2/3 were included in the final analysis. Although 7 parameters differed significantly between EED and normal biopsies in regression models, only 5 (blunted villus architecture, increased intraepithelial lymphocytosis, goblet cell depletion, Paneth cell depletion, and reduced intramucosal Brunner's glands) were required to create a total score percentage (TSP-5) that correctly identified EED against normal biopsies (AUC: 0.992; 95% CI: 0.983, 0.998). Geographic comparisons showed more severe goblet cell depletion in Bangladesh and more marked intraepithelial lymphocytosis in Pakistan. CONCLUSIONS: This scoring system involving 5 histologic parameters demonstrates very high discrimination between EED and normal biopsies, indicating that this scoring system can be applied with confidence to studies of intestinal biopsies in EED.

The reciprocal relationship between education and health is well-established, emphasizing the need for integrating health, nutrition, and well-being components into educational sector planning. Despite widespread acknowledgment of this need, countries lack concrete measures to achieve this integration. We examine challenges that countries have faced and the progress they have made in integrating these components into education sector plans and review the extent to which existing educational planning guidelines and tools address health and well-being. The review reveals a significant underrepresentation of health, well-being, and related themes in existing educational planning frameworks. Recent tools and frameworks developed to support a more holistic approach to education have not yet been widely adopted in standard education sector planning processes. The implementation of such approaches remains inconsistent, with significant barriers including limited cross-sectoral collaboration, lack of capacity, and insufficient funding, among others. Addressing these gaps requires improved guidance, technical support, and a multisectoral approach to education planning that includes health, nutrition, and well-being as fundamental components of foundational learning, supported by political commitment, capacity, and adequate financing.

Childhood nutritional status serves as a lens through which nations and communities identify missed opportunities to improve health and wellbeing across the life cycle, as well as economic development and other related sectors. Countries have committed to the global nutrition targets endorsed by the World Health Assembly in 2012, which were included in the Sustainable Development Goals framework under the target to end all forms of malnutrition by 2030. The child malnutrition indicators for tracking countries' progress toward the agreed-upon targets are based on standard definitions of nutritional status against the widely adopted and used World Health Organization (WHO) Child Growth Standards. The standards were based on a sample of healthy breastfed infants and young children from diverse ethnic backgrounds and cultural settings as part of the WHO Multicentre Growth Reference Study. The WHO Child Growth Standards developed represent the best description of physiological growth for children aged <5 y. The standards depict normal early childhood growth under optimal environmental conditions and can be used to assess children everywhere, regardless of ethnicity, socioeconomic status, and type of feeding.
RESUMO
Effective community entry processes influence community participation and acceptance of public health interventions. Though there is a growing body of literature on the importance of community partnerships, there is a lack of pragmatic and practical documentation of the experiences involved in the community entry process as it relates to culturally sensitive topics such as child marriage which can help to support researchers working in this field. This article highlights key themes related to knowledge of the community, effective communication, cultural sensitivity, coproduction and giving feedback which help to build trust between the community members and the research team. Institutional representation, not managing expectations, and lack of clarity, along with personal opinions of community gatekeepers can create challenges for the fostering of trustworthy relationships with the community. These realities must be actively addressed right at the onset of the process between the research team and community stakeholders. Researchers can develop trust, form connections and engage different communities by working with local groups and leaders, using culturally appropriate methods, and addressing community concerns. Future projects working with communities on child marriage in Nigeria and other countries would benefit from the reflections presented in this paper.

INTRODUCTION: To ensure that humanitarian action is disability-inclusive, evidence is needed to understand how different strategies to support children living with disabilities and their families can work in these settings. Evidence from other contexts suggests support groups can improve caregiver quality of life (QOL). This study reports an evaluation of the 'Mighty Children' programme a participatory educational support group programme for caregivers of children living with disability in Kabul province, Afghanistan. METHODS: We conducted a mixed-methods realist-informed before-and-after study to measure change in caregiver-reported QOL and explore how and for whom the programme worked, and in what contexts. Female caregivers of children with any disability were recruited through clinics in urban Kabul (n=3) and rural Paghman district (n=3). We collected quantitative data on QOL pre/post programme using the Paediatric Quality of Life Inventory Family Impact Module (PedsQL-FIM). Qualitative data were collected through facilitator and participant focus groups postprogramme. RESULTS: 118 caregivers participated in two cohorts (November 2020, February 2021). Caregivers expressed a significant increase in QOL from baseline to programme completion (t(125)=-10.7, p≤0.0001). Participation in cohort 2 was associated with the greatest PedsQL-FIM change.Qualitative data revealed positive changes postprogramme in five key areas: caregiver mindset, parenting practices, disability-inclusive behaviours, psychological well-being and child functioning. These changes were seen as both outcomes and mechanisms influencing the primary outcome of QOL. Mechanisms that mediated these changes included increased knowledge of disability and the core acceptance and commitment therapy components of mindfulness and acceptance. CONCLUSION: The Mighty Children caregiver support programme for children living with disability in Afghanistan was associated with improved caregiver QOL. Further studies are warranted to explore pathways to scale, sustainability and potential application in other settings.

OBJECTIVE: To evaluate the safety of short-term use of inhaled salbutamol in children under 2 years of age with acute wheezing. DATA SOURCES: Electronic databases (PubMed, Trip, MEDLINE) and the Cochrane Library were searched for studies published up to October 2022. STUDY SELECTION: The search was restricted to randomised controlled trials published in English regarding the safety of inhaled salbutamol in wheezing children under the age of 2. DATA EXTRACTION AND SYNTHESIS: The literature search strategy yielded 3532 references. The meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MAIN OUTCOMES AND MEASURES: The incidence of adverse reactions associated with inhaled salbutamol administration compared with placebo. RESULTS: A total of 24 records were included. In 7 studies involving 597 patients, inhaled salbutamol was compared with controls and no statistically significant difference in the incidence of adverse drug reactions was found between the two groups (OR 2.12, 95% CI 0.69 to 6.51; p=0.19). Salbutamol administration via nebulisation was associated with an increased incidence of adverse reactions (OR 6.76, 95% CI 2.01 to 22.71; p=0.002). None of the studies reported severe cardiac side effects that necessitated withdrawal from the study following salbutamol administration. Only one study reported a significant non-cardiac side effect (severe tremulousness) that necessitated withdrawal from therapy. CONCLUSIONS: Inhaled salbutamol can be safely used in children under 2 years of age with acute wheeze with the administration via a metered-dose inhaler being potentially safer than a nebulised formulation. Neither of the formulations was associated with severe adverse effects.
RESUMO
OBJECTIVE: To assess natural history of otitis media with effusion (OME)-related hearing loss and OME causing hearing loss in children under 12 years. METHODS: Embase, MEDLINE, CINAHL, INAHTA database, CENTRAL, CDSR, Epistemonikos and PsycINFO were searched to identify observational single group studies, and comparative studies with untreated control arms published in English up to June 2022, reporting natural history of OME-related hearing loss and OME causing hearing loss. Risk of bias and overall quality of evidence were assessed using the JBI (Joanna Briggs Institute (JBI) checklist and GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology, respectively. RESULTS: Thirteen studies with 24-639 children were included. Resolution of OME-related hearing loss was 50% by 3 months, 60% by 6 months and 61-77% by 12 months. Resolution of OME causing hearing loss (OME of <1 month, >3 months, >6 months or unknown duration before follow-up) was 23-55% by 3 months, 20-50% by 6 months, 31% by 9 months and 21-93% by 12 months, depending on population and how resolution was defined. Resolution of chronic OME (OME of >12 months duration before follow-up) was only 7% by 1 month, 12% by 6 months and 6% by 12 months. Resolution was only 42% by 57 months in children with primary ciliary dyskinesia. CONCLUSIONS: There was greater resolution of OME-related hearing loss over longer follow-up periods. Resolution of OME causing hearing loss also showed a trend towards greater resolution over longer follow-up periods; however, this did not follow a linear pattern, potentially due to differences in populations and definitions of resolution across studies.
