Hearing impairment negatively affects well-being and is a major contributor to years lived with disability. The World Health Organization (WHO) estimates that 466 million people were living with disabling hearing impairment in 2018 and this estimate is projected to rise to 630 million by 2030 and to over 900 million by 2050. However, these projections are based on a hearing impairment classification that does not fully reflect the provisions of the International classification of functioning, disability and health for assessing all forms of functional impairments. Here we make the case for a review of the concept of disabling hearing loss adopted by WHO after the recommendation of the Global Burden of Disease (GBD) Expert Group on Hearing Impairment in 2008. The need for an independent classification system for all impairments and disabilities as a complement to the well-established International statistical classification of diseases and related health problems, was first suggested in 1976 by the World Health Assembly. As a result, in 1980 WHO developed the International classification of impairments, disabilities and handicaps. One of the key features of this system was the use of qualifiers such as mild, moderate, severe and profound to distinguish various levels of observed or measured deviations outside of the range considered for normal functioning for any health condition. This categorization has been reinforced in the subsequent revisions to the system, such as the International Classification of Functioning, Disability and Health, and accompanied with descriptions of typical problems encountered in daily activities at various levels of severity. The classification, notably, does not use the term disabling, as it recognizes the needs of all persons with functional impairments for appropriate intervention.

At any age, disabling hearing impairment has a profound impact on interpersonal communication, psychosocial well-being, quality of life and economic independence. According to the World Health Organization's estimates, the number of people with such impairment increased from 42 million in 1985 to about 360 million in 2011. This last figure includes 7.5 million children less than 5 years of age. In 1995, a \"roadmap\" for curtailing the burden posed by disabling hearing impairment was outlined in a resolution of the World Health Assembly. While the underlying principle of this roadmap remains valid and relevant, some updating is required to reflect the prevailing epidemiologic transition. We examine the traditional concept and grades of disabling hearing impairment - within the context of the International Classification of Functioning, Disability and Health - as well as the modifications to grading that have recently been proposed by a panel of international experts. The opportunity offered by the emerging global and high-level interest in promoting disability-inclusive post-2015 development goals and disability-free child survival is also discussed. Since the costs of rehabilitative services are so high as to be prohibitive in low- and middle-income countries, the critical role of primary prevention is emphasized. If the goals outlined in the World Health Assembly's 1995 resolution on the prevention of hearing impairment are to be reached by Member States, several effective country-level initiatives - including the development of public-private partnerships, strong leadership and measurable time-bound targets - will have to be implemented without further delay.

Background There are over 53million children worldwide under five with developmental disabilities who require effective interventions to support their health and well-being. However, challenges in delivering interventions persist due to various barriers, particularly in low-income and middle-income countries. Methods We conducted a global systematic umbrella review to assess the evidence on prevention, early detection and rehabilitation interventions for child functioning outcomes related to developmental disabilities in children under 5 years. We focused on prevalent disabilities worldwide and identified evidence-based interventions. We searched Medline, Embase, PsychINFO, and Cochrane Library for relevant literature from 1st January 2013 to 14th April 2023. A narrative synthesis approach was used to summarise the findings of the included meta-analyses. The results were presented descriptively, including study characteristics, interventions assessed, and outcomes reported. Further, as part of a secondary analysis, we presented the global prevalence of each disability in 2019 from the Global Burden of Disease study, identified the regions with the highest burden and the top ten affected countries. This study is registered with PROSPERO, number CRD42023420099. Results We included 18 reviews from 883 citations, which included 1,273,444 children under five with or at risk of developmental disabilities from 251 studies across 30 countries. The conditions with adequate data were cerebral palsy, hearing loss, cognitive impairment, autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder. ASD was the most prevalent target disability ( n  = 8 reviews, 44%). Most reviews ( n  = 12, 67%) evaluated early interventions to support behavioural functioning and motor impairment. Only 33% ( n  = 10/30) of studies in the reviews were from middle-income countries, with no studies from low-income countries. Regarding quality, half of reviews were scored as high confidence ( n  = 9/18, 50%), seven as moderate (39%) and two (11%) as low. Conclusions We identified geographical and disability-related inequities. There is a lack of evidence from outside high-income settings. The study underscores gaps in evidence concerning prevention, identification and intervention, revealing a stark mismatch between the available evidence base and the regions experiencing the highest prevalence rates of developmental disabilities.

From a developmental perspective, optimal speech and language outcome is indisputably the primary motivation for neonatal hearing screening of infants with congenital or early-onset hearing loss (PCHL). This paper additionally outlines more broadly the potential value of early hearing detection and intervention in resource-poor countries against the backdrop of limitations of primary prevention of PCHL based on a review of literature from low-income and middle-income countries with per capita incomes of approximately US$6000 or less. It establishes the scientific and developmental foundation for priority consideration for neonatal hearing screening and intervention in any global initiatives for effective early childhood development programmes in resource-limited countries. It also highlights approaches to addressing the various challenges to implementing effective early hearing detection and intervention programmes, and concludes with a discussion on the pivotal role of paediatricians in facilitating timely referral for requisite tests and (re)habilitative services especially for infants with established risk factors.

Background Exclusive breastfeeding (EBF) has important benefits for both the mother and child. In India, no nationwide studies have examined patterns of EBF in the past decade to inform national and subnational breastfeeding programmes. The present study aimed to investigate the regional prevalence and determinants of EBF in India. Methods This study used a total weighted sample of 21,352 from the 2015–2016 India National Family Health Survey. EBF was measured as the proportion of infants 0–5 months of age who received breast milk as the only source of nourishment, based on mother’s recall on feeds given to the infant 24 h before the survey. The prevalence of EBF and other breastfeeding patterns were estimated by region, and multivariable logistic regression that adjusted for clustering and sampling weights was used to investigate the association between the study factors (child, maternal, household, health service and community factors) and EBF by regional areas in India. Results This study indicated that wide differences in the prevalence of EBF and other childhood feeding practices exist across regions of India, where Southern India had the highest EBF prevalence (79.2%) and the North-East reported the lowest (68.0%). EBF prevalence decreased with infant age, dropping faster in the South (43.7% at 5 months) compared to the North-East region (54.0% at 5 months). Similarly, substantial variations in key determinants of EBF were evident by region, where higher birth order was the only common factor associated with non-EBF across all regions. Key modifiable determinants of non-EBF included higher maternal education in the South and belonging to rich households in Central India, while those for EBF were higher maternal education in the Central region and frequent antenatal care (≥ 4) visits in Northern India. Conclusion This study demonstrates wide variations in regional prevalence and determinants of EBF in India. Improving EBF participation in India would require multifaceted national and subnational efforts that include dedicated funds and the establishment of appropriate policy and interventions that are consistently monitored and evaluated.

For example, in 1995, the World Health Assembly passed a resolution on the prevention and control of major causes of avoidable hearing impairment and for early detection of hearing loss in babies, toddlers, and children, as well as in the elderly, within the framework of primary health care.11 This resolution was predicated on concerns about the growing problem of disabling but largely preventable hearing impairment worldwide (affecting an estimated 120 million people in 1995) and the recognition of its adverse consequences for optimum childhood development, especially for language acquisition and educational achievement.

Mothers are frequently the first to observe the onset of jaundice in their newborn infants before the decision to seek treatment. However, simple-to-use tools that could facilitate early detection of jaundice and assist mothers to seek professional care, especially after hospital discharge, are rare. This study therefore, set out to evaluate the performance of a -two-color icterometer (Bilistrip™) as a possible screening tool for detecting significant jaundice by mothers or care-givers in the first week of life. Prior to discharge, mothers in a maternity hospital were trained to use the Bilistrip™ on the blanched skin of their baby's nose to ascertain absence (Light Yellow) or presence (Dark Yellow) of significant jaundice. Their babies had transcutaneous bilirubin (TcB) measurements independently, along with total serum bilirubin (TSB) if indicated. The reliability of Bilistrip™ as a screening test for significant jaundice was determined at different TcB and TSB thresholds. The predictive performance of Bilistrip™ was also evaluated with multivariable logistic regression. Some 2492 mother-infant pairs were enrolled over 15 months, of which 347 (13.9%) chose Dark Yellow. The mean TcB for Dark Yellow (10mg/dL) was significantly higher (p<0.001) than for Light Yellow (6.1mg/dL). Bilistrip™ showed increasing sensitivity (47.0% - 92.6%) and negative predictive value (NPV) (91.4% - 99.9%) for selected TcB thresholds (≥10mg/dL, ≥12mg/dL, ≥15mg/dL, and ≥17mg/dL). Among neonates with TSB measurements (n = 124), Bilistrip™ was associated also with increasing sensitivity (86.8% - 100%) and NPV (62.5% - 100%). The sensitivity and NPV for detecting neonates requiring phototherapy were 95.8% respectively. Only one of the 24 neonates who required phototherapy was missed by the Bilistrip™. Bilistrip™ is a potential decision-making tool for empowering mothers to detect neonates with clinically significant jaundice that may require close monitoring or treatment, and neonates not requiring treatment for jaundice in the first week of life.

Filtered-sunlight phototherapy (FSPT) that blocks ultraviolet light and reduces infrared radiation is safe and non-inferior to intensive electric phototherapy (IEPT) for treating mild-to-severe neonatal hyperbilirubinemia. In this randomized non-inferiority trial, the safety, efficacy, exchange transfusion (ET), and mortality rates of FSPT versus IEPT among Nigerian neonates with severe-to-hazardous hyperbilirubinemia were investigated. Safety was defined as the absence of hyperthermia, hypothermia, dehydration, or sunburn; efficacy by the proportion of assessable treatment days during which total serum or plasma bilirubin (TSB) increased by < 0.2 mg/dL/hr for newborns aged ≤ 72 h-old or decreased for newborns > 72 h-old. A treatment day was deemed assessable if a neonate received phototherapy for ≥ 4 h, and non-inferiority was inferred for differences within a 10% margin. We enrolled 192 newborns (admission TSB ≤ 62 mg/dL), assigned to FSPT (n = 98) or IEPT (n = 94). FSPT was effective on 94.2% of the assessable treatment days compared with 97.1% for IEPT. The mean difference in efficacy between FSPT and IEPT was -2.9%, 95% CI: -7.6, 1.9). 2.6% of newborns who received FSPT developed controlled hyperthermia, and no baby met the criteria for withdrawal for safety reasons. Overall, 50.6% (39/77) of newborns who received FSPT and 53.7% (51/95) of newborns who received IEPT had ET (p = 0.89) and 7 in each group (9.1% vs 7.4%; p = 0.86) died. In conclusion, FSPT is safe and non-inferior to IEPT for treating neonates with severe-to-hazardous hyperbilirubinemia, it is not associated with significantly higher rates of ET and mortality and should be considered where practicable when IEPT cannot be assured.
