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.

The World Health Organization (WHO) is releasing the second edition of its Global Accelerated Action for the Health of Adolescents (AA-HA!) guidance. The document aims to equip governments to respond to the health and well-being challenges, opportunities and needs of adolescents.
The guidance pro...vides the latest available data on adolescent health and well-being. It also outlines an updated list of core indicators that data should be collected on. Globally, road injury was the top cause of death for adolescent males in 2019. Among female adolescents, the leading causes of death were diarrhoeal diseases among the younger group (10-14 years) and tuberculosis (TB) in the older group (15-19 years).
Over the last 20 years, mortality rates have declined among adolescents globally, with the largest decline in older (15–19 years) adolescent girls. For non-fatal diseases, the burden has not improved over the past two decades, with the main causes of ill health in this category being: mental health conditions (depressive and anxiety disorders, childhood behavioural disorders), iron deficiency anaemia, skin diseases and migraine.
Adolescent well-being depends on a range of factors, including healthy food, education, life skills and employability, connectedness, feeling valued by society, safe and supportive environments, resilience, and the freedom to make choices. To take an appropriately holistic approach, the guidance outlines how to take crosscutting action to support adolescent health and well-being, with mutually reinforcing interventions across sectors, such as health, education, social protection, and telecommunications. Targeted efforts are also required to engage adolescents, as they trust health systems less than adults do and are especially vulnerable to modern-day trends, like online bullying and gaming.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to prevent and control CVD, in addition to multisector...al population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Community-based strategies play a significant role in many health systems in low- and middle-income countries, especially in light of critical shortages in the health workforce. The term community health worker has been used to refer to volunteers and salaried, professional or lay health workers wit...h a wide range of training, experience, scope of practice and integration in health systems. In the context of this study, we use the term community-based practitioner (CBPs) to reflect the diverse nature of these cadres of health workers.
CBPs provide preventive, promotive, curative and palliative services across a range of areas, including reproductive, maternal, newborn and child health, HIV, tuberculosis, malaria, control of other endemic diseases, and noncommunicable diseases. Significant evidence has emerged over the past two decades on their effectiveness, which has triggered interest in the potential to use their services to expand access to care, in particular in rural and underserved areas where deployment and retention of more qualified health workers is problematic. Calls have been made to integrate CBP programmes in human resources and health strategies, and to scale up rapidly the extent and coverage of CBP initiatives.

This fourth annual report monitors global progress towards the 2023 target for global elimination of industrially produced trans-fatty acids (TFA), highlighting achievements during the past year (October 2021 – September 2022). Countries are responding to the World Health Organization (WHO) call t...o action by putting into place best-practice TFA policies. Mandatory TFA policies are currently in effect for 3.4 billion people in 60 countries (43% of the world population); of these, 43 countries have best-practice policies in effect, covering 2.8 billion people (36% of the world population).
Over the past year, several additional countries took action to eliminate industrially produced TFA: best-practice policies came into effect in India in January 2022, Uruguay in May 2022 and Oman in July 2022. Best-practice policies were passed in Bangladesh in November 2021 (to come into effect in December 2022) and in Ukraine in September 2020 (to come into effect in October 2023), best-practice TFA policies are projected to pass soon in Mexico, Nigeria and Sri Lanka.
