Background
Noncommunicable diseases are major contributors to morbidity and mortality worldwide. Modifying the risk factors for these conditions, such as physical inactivity, is thus essential. Addressing the context or circumstances in which physical activity occurs may promote physical activity a...t a population level. We assessed the effects of infrastructure, policy or regulatory interventions for increasing physical activity.
Methods
We searched PubMed, Embase and clinicaltrials.gov to identify randomised controlled trials (RCTs), controlled before-after (CBAs) studies, and interrupted time series (ITS) studies assessing population-level infrastructure or policy and regulatory interventions to increase physical activity. We were interested in the effects of these interventions on physical activity, body weight and related measures, blood pressure, and CVD and type 2 diabetes morbidity and mortality, and on other secondary outcomes. Screening and data extraction was done in duplicate, with risk of bias was using an adapted Cochrane risk of bias tool. Due to high levels of heterogeneity, we synthesised the evidence based on effect direction.
Results
We included 33 studies, mostly conducted in high-income countries. Of these, 13 assessed infrastructure changes to green or other spaces to promote physical activity and 18 infrastructure changes to promote active transport. The effects of identified interventions on physical activity, body weight and blood pressure varied across studies (very low certainty evidence); thus, we remain very uncertain about the effects of these interventions. Two studies assessed the effects of policy and regulatory interventions; one provided free access to physical activity facilities and showed that it may have beneficial effects on physical activity (low certainty evidence). The other provided free bus travel for youth, with intervention effects varying across studies (very low certainty evidence).
Conclusions
Evidence from 33 studies assessing infrastructure, policy and regulatory interventions for increasing physical activity showed varying results. The certainty of the evidence was mostly very low, due to study designs included and inconsistent findings between studies. Despite this drawback, the evidence indicates that providing access to physical activity facilities may be beneficial; however this finding is based on only one study. Implementation of these interventions requires full consideration of contextual factors, especially in low resource settings.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

These guidelines for the prevention and management of cardiovascular diseases are a critical ingredient for streamlining care across the entire health services provision continuum. They are a strategic component in achieving universal health coverage, securing affordable heal...th care and improving the livelihood of all Kenyans which in turn will guarantee a healthy nation working towards sustainable development and prosperity.These guidelines bring to the fore the need for availability of skilled human resource, sustained adequate funding and partnership building at all levels of governance. It provides clear roles for health workers at the different levels of our devolved system which will ensure a harmonized referral system with basic cardiovascular diseases treatment services available closest to the people while decongesting the county and national referral facilities.

2nd edition, July 2021. This WHO and HRP guideline is designed to help countries make faster progress, more equitably, on the screening and treatment of cervical cancer. It includes some important shifts in WHO’s recommended approaches to cervical screening, and includes a total of 23 recommendati...ons and 7 good practice statements.
Among the 23 recommendations, 6 are identical for both the general population of women and for women living with HIV and 12 are different and specific for each population.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

Declarations of interests were collected from all external contributors and assessed for any conflicts of interest. Summaries of the reported interests can be found on the SAGE meeting website and SAGE Covid-19 Working Group webpage. This guidance should be considered along with the broader COVID-...19 policy advice to WHO member states and in particular the advice on how to reach the COVID-19 vaccination targets.

Cervical cancer continues to be a significant public health problem and a major cause of premature mortality among women, disproportionately affecting the socioeconomically disadvantaged population in low- and middle-income countries (LMICs). In the absence of implementing the known evidence-based, ...cost-effective interventions, the number of deaths per year is projected to reach approximately 416 000 globally in 2035. It was estimated in 2020 that 32% of incident cervical cancer cases and 34% of cervical cancer deaths in the world occurred in the 11 Member States of the WHO South-East Asia (SEA) Region. In 2020, 190 874 new cases and 116 015 deaths were estimated due to cervical cancer, which is the third commonest cancer in the Region

Pneumonia and diarrhoea account for 23% of under-five mortality and were responsible for an estimated 1.17 million deaths in children under five globally. Furthermore, pneumonia and diarrhoea were responsible for 18% of mortality in children 5–9 years of age, resulting in an estimated 86 000 preve...ntable deaths globally in 2021. Existing World Health Organization (WHO) guidance on the clinical management of pneumonia and diarrhoea has mainly focused on children less than 5 years of age.

Immunization is one of the most cost-effective public health interventions to date, saving an estimated 2 to 3 million lives each year. As a direct result of immunization, the world is closer than ever to eradicating polio, and deaths from measles – a major child killer – have declined by 73 per... cent worldwide between 2000 and 2018, saving an estimated 23.2 million children’s lives. The emergence of COVID-19, however, threatens to reverse this progress by severely limiting access to life-saving vaccines.

Diets are changing everywhere, and the burden of disease associated with unhealthy diets is a worldwide concern. Measurement and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the wor...ld is evolving.
This report assesses the validity, usefulness and fitness for purpose of existing healthy diet metrics as global and national monitoring indicators, presents a comparative assessment of selected healthy diet metrics and discusses priorities and opportunities to improve diet monitoring. This report is an important first step of the Healthy Diets Monitoring Initiative to respond to the need for developing healthy diets metrics for assessing and monitoring diets at national and global level.
