Infrastructure, policy and regulatory interventions to increase physical activity to prevent cardiovascular diseases and diabetes: a systematic review

Durão, S.; Burns, J.; Schmidt, B. et al. BMC Public Health (2023) CC

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. more

Therapeutics and COVID-19 (Living Guideline, 10 November 2023)

World Health Organization WHO (2023) C_WHO

WHO has updated its guidelines for COVID-19 therapeutics, with revised recommendations for patients with non-severe COVID-19. This is the 13th update to these guidelines. Updated risk rates for hospital admission in patients with non-severe COVID-19 The guidance includes updated risk rates for... hospital admission in patients with non-severe COVID-19. The current COVID-19 virus variants tend to cause less severe disease while immunity levels are higher due to vaccination, leading to lower risks of severe illness and death for most patients. This update includes new baseline risk estimates for hospital admission in patients with non-severe COVID-19. The new ‘moderate risk’ category now includes people previously considered to be high risk including older people and/or those with chronic conditions, disabilities, and comorbidities of chronic disease. The updated risk estimates will assist healthcare professionals to identify individuals at high, moderate or low risk of hospital admission, and to tailor treatment according to WHO guidelines: **High: **People who are immunosuppressed remain at higher risk if they contract COVID-19, with an estimated hospitalization rate of 6%. **Moderate: **People over 65 years old, those with conditions like obesity, diabetes and/or chronic conditions including chronic obstructive pulmonary disease, kidney or liver disease, cancer, people with disabilities and those with comorbidities of chronic disease are at moderate risk, with an estimated hospitalization rate of 3%. Low: Those who are not in the high or moderate risk categories are at low risk of hospitalization (0.5%). Most people are low risk. Review of COVID-19 treatments for people with non-severe COVID-19 WHO continues to strongly recommend nirmatrelvir-ritonavir (also known by its brand name ‘Paxlovid’) for people at high-risk and moderate risk of hospitalization. The recommendations state that nirmatrelvir-ritonavir is considered the best choice for most eligible patients, given its therapeutic benefits, ease of administration and fewer concerns about potential harms. Nirmatrelvir-ritonavir was first recommended by WHO in April 2022. If nirmatrelvir-ritonavir is not available to patients at high-risk of hospitalization, WHO suggests the use of molnupiravir or remdesivir instead. WHO suggests against the use of molnupiravir and remdesivir for patients at moderate risk, judging the potential harms to outweigh the limited benefits in patients at moderate risk of hospital admission. For people at low risk of hospitalization, WHO does not recommend any antiviral therapy. Symptoms like fever and pain can continue to be managed with analgesics like paracetamol. WHO also recommends against use of a new antiviral (VV116) for patients, except in clinical trials. The update also includes a strong recommendation against the use of ivermectin for patients with non-severe COVID-19. WHO continues to advise that in patients with severe or critical COVID-19, ivermectin should only be used in clinical trials. more
