Hearing loss grades and the International classification of functioning, disability and health

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. The case is made 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.

Addressing the rising prevalence of hearing loss

Hearing loss is the fourth highest cause of disability globally, with an estimated annual cost of over 750 billion dollars. These facts are well known and have contributed to growing global consciousness on the need for accessible hearing care in all regions of the world. Looking forward however, the demand for hearing care is likely to grow significantly in coming decades. This report highlights the potential escalation of hearing loss to the middle of the century, and focusses on the factors responsible for hearing loss and the means to address them. 

WHO estimates in 2008 found that 360 million people worldwide live with disabling hearing loss, including 32 million children and 180 million older adults. The most recent estimations place this figure at over 466 million people with disabling hearing loss in 2018. The main areas of the world affected by disabling hearing loss are the South Asian, Asia Pacific and Sub-Saharan African regions, with a prevalence rate almost four times that of the high income regions.

 

Measures to address these concerns deal with: prevention of infections in mothers and babies; chronic ear infections; noise exposure; and ototoxic hearing loss.

 

Public health aspects are highlighted.

Global and regional estimates of violence against women : prevalence and health effects of intimate partner violence and non-partner sexual violence

"The report presents the first global systematic review of scientific data on the prevalence of two forms of violence against women: violence by an intimate partner (intimate partner violence) and sexual violence by someone other than a partner (non-partner sexual violence). It shows, for the first time, global and regional estimates of the prevalence of these two forms of violence, using data from around the world. Previous reporting on violence against women has not differentiated between partner and non-partner violence"

This report "reviews evidence about the situation of people with disabilities around the world. Following chapters on understanding disability and measuring disability, the report contains topic-specific chapters on health; rehabilitation; assistance and support; enabling environments; education; and employment. Within each chapter, there is a discussion of the barriers confronted, and case studies showing how countries have succeeded in addressing these by promoting good practice. In its final chapter, the report offers nine concrete recommendations for policy and practice which if put in place could lead to real improvements in the lives of people with disability"

Preventing intimate partner and sexual violence against women : taking action and generating evidence

"This document aims to provide sufficient information for policy-makers and planners to develop data-driven and evidence-based programmes for preventing intimate partner and sexual violence against women. Chapter 1 outlines the nature, magnitude and consequences of intimate partner and sexual violence within the broader typology of violence. Chapter 2 identifies the risk and protective factors for such violence and the importance of addressing both risk and protective factors in prevention efforts. Chapter 3 summarizes the scientific evidence base for primary prevention strategies, and describes programmes of known effectiveness, those supported by emerging evi-dence and those that could potentially be effective but have yet to be sufficiently evaluated for their impact. Chapter 4 presents a six-step framework for taking action, generating evidence and sharing results. In the closing section, several future research priorities are outlined and a number of key conclusions drawn"

WHO’s multi-country study on women’s health and domestic violence against women : summary report of initial results on prevalence, health outcomes and women's responses

"Violence against women by an intimate partner is a major contributor to the ill-health of women. This study analyses data from 10 countries and sheds new light on the prevalence of violence against women in countries where few data were previously available. It also uncovers the forms and patterns of this violence across different countries and cultures, documenting the consequences of violence for women’s health. This information has important implications for prevention, care and mitigation... The high rates documented by the Study of sexual abuse experienced by girls and women are of great concern, especially in light of the HIV epidemic. Greater public awareness of this problem is needed and a strong public health response that focuses on preventing such violence from occurring in the first place...This study will help national authorities to design policies and programmes that begin to deal with the problem"
