Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

Diabetes Burdens: 10.5% adults around the world are currently loving with diabetes.
The aim of this toolkit is to guide countries on how to best estimate their current burden of dengue by combining existing data from dengue surveillance systems with on-going research efforts to measure the community burden
of dengue.
The article provides a systematic analysis estimating the prevalence of Chronic Obstructive Pulmonary Disease (COPD) across Africa. It highlights the significant health burden COPD imposes on the continent, emphasizing varying prevalence rates influenced by factors such as tobacco smoking, exposure ...to biomass fuel, and occupational hazards. The analysis reveals substantial gaps in data and disparities in COPD diagnosis and management across different African countries. The authors call for more comprehensive data collection, increased awareness, and better healthcare infrastructure to effectively address and manage COPD in Africa.

The burden of diabetes is enormous, positioning it as one of the main challenges facing public health today. Currently, it is estimated that 62 million people are living with diabetes in the Region of the Americas and projections show its prevalence will continue rising over the following years. The... Region shows the highest number of years of healthy life lost (through either disability or premature death) due to diabetes worldwide. The high costs associated with its treatment produce a heavy economic burden. Its complications can seriously affect the quality of life of people living with diabetes, their families, and society and overload health systems. This report shows the latest internationally comparable data on diabetes and its main risk factors by year, country, and sex. It also includes a summary of the countries health systems’ response to diabetes, including national plans, targets, surveillance, guidelines, and access to essential drugs and technologies, and synthesizes information about diabetes-related complications and the close relationship between diabetes and other pathologies, such as cardiovascular diseases, tuberculosis, and COVID-19. The data presented here reveal that, despite advances in national responses, diabetes continues to expand, and our response remains insufficient. This report aims to draw attention to the urgent need to strengthen efforts to prevent, diagnose, and control diabetes in the Region of the Americas.

Non-communicable diseases (NCDs) pose a substantial threat to many health systems, especially in low-income and middle-income countries (LMICs) where they are already overstretched. In the past few decades, deaths from NCDs in LMICs have spiked, whereas numbers in high-income countries have stabilis...ed. Worryingly, a large proportion of deaths from NCDs (29%) in LMICs occur among people younger than 60 years compared with the proportion in high-income countries (13%). This finding has been attributed to poor access to effective and equitable health-care services in most LMICs. The threat of NCDs in LMICs was recognised by the UN 2011 High-Level Meeting, and is now featured in Sustainable Development Goal 3 in the form of reducing premature mortality from NCDs by one-third before 2030. Cardiovascular diseases (CVDs) are the leading cause of deaths from NCDs (ie, 48% of all NCDs deaths). Therefore, substantial reductions in CVDs will have a major impact on reducing the overall burden of NCDs globally. The good news is that most CVDs can be prevented by addressing the key underlying behavioural risk factors, such as physical inactivity, unhealthy diet, tobacco use, and harmful use of alcohol, through population-wide approaches. Among individuals with or at high risk of CVD, early detection and effective management with appropriate counselling and medicines can reduce cardiovascular deaths substantially.
The importance of effective treatment for CVD has been recognised in the Global NCD Action Plan 2013–20, for which one of the nine global targets is that at least 50% of eligible individuals should receive drug therapy and counselling to prevent heart attacks and strokes by 2025.5 Although admirable, this is a hard target to achieve given that secondary prevention strategies in LMICs are often unaffordable or unavailable.

Since 2016, the Pan American Health Organization (PAHO) has been promoting the implementation of the HEARTS Initiative in the Americas as a regional adaptation of the World Health Organization's Global HEARTS Initiative. During this time, 33 countries in the Region of the Americas have committed to ...implementing HEARTS, and PAHO has developed many technical resources to support them. Most of these resources are clinical tools for primary healthcare teams and focus on quality improvement. This compendium aims to group all these clinical tools in a single document under a simple format that facilitates their practical implementation in daily clinical practice. The reader will notice that each tool is summarized on a single page and presented in a modular format. Therefore, each tool can be used together or separately as needed. In addition, at the bottom of each tool, the reader will find the references and hyperlinks to access full texts in case deeper knowledge is required.

As the culminating volume in the DCP3 series, volume 9 will provide an overview of DCP3 findings and methods, a summary of messages and substantive lessons to be taken from DCP3, and a further discussion of cross-cutting and synthesizing topics across the first eight volumes. The introductory chapte...rs (1-3) in this volume take as their starting point the elements of the Essential Packages presented in the overview chapters of each volume. First, the chapter on intersectoral policy priorities for health includes fiscal and intersectoral policies and assembles a subset of the population policies and applies strict criteria for a low-income setting in order to propose a "highest-priority" essential package. Second, the chapter on packages of care and delivery platforms for universal health coverage (UHC) includes health sector interventions, primarily clinical and public health services, and uses the same approach to propose a highest priority package of interventions and policies that meet similar criteria, provides cost estimates, and describes a pathway to UHC.

Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.

This report is part of the gender and noncommunicable diseases (NCDs) initiative launched by the WHO Regional Office for Europe, which aims to strengthen the response to NCDs through a gender approach. It is part of a series of country profiles and a synthesis report. The country profile of Ukraine ...presents a gender analysis of the WHO STEPwise survey (STEPS) data to support international commitments to reducing the burden of NCDs with evidence and knowledge exchange. A gender analysis of STEPS NCD risk-factor survey data describes how risk factors for chronic diseases differ between and among men and women by exploring and tracking the direction and magnitude of trends in risk factors and accessing services by sociodemographic variables. Important differences hide even in sex-disaggregated data that need to be unpacked through sociodemographic characteristics, because men and women are not homogenous groups. The report also recognizes gaps in evidence and calls for further analysis of the impact of gender-based inequalities.

Since the launch of the 2012–2020 World Health Organization (WHO) road map for the control, elim-ination and eradication of neglected tropical diseases (NTDs) (1), considerable progress against NTDs has been made. Between 2010 and 2020, the number of people requiring interventions against NTDs glo...bally fell by 600 million, and 42 countries, areas and territories eliminated at least one NTD (2). In January 2021, a new NTD road map for 2021–2030 (2) was launched, setting future targets and mile-stones for 20 diseases and disease groups. The road map also sets cross-cutting targets, including for strengthened capacity of national health systems to deliver interventions through existing infrastructure.
