RESUMO
OBJECTIVES: To examine the impact of COVID-19 vaccination on hospital admissions in England in 2021. DESIGN: Observational study of emergency admissions for COVID-19 by vaccination status in people 16 years and over in England. SETTING: Hospitals in England. PARTICIPANTS: A total of 48.1 million people registered with an English GP, aged ≥16 years with a recent NHS contact. MAIN OUTCOME MEASURES: Emergency hospital admissions with a primary diagnosis of COVID-19 between 1 January and 31 December 2021. Monthly admission rates were directly standardised for age, sex, risk category and vaccination dose to estimate vaccine effectiveness (VE) over time, between vaccine doses, age groups and risk groups. RESULTS: A total of 192,047 hospital admissions were included. The unvaccinated admission rate was higher in December 2021 (6.1 admissions per 100,000 person-days; 95% CI: 5.9 to 6.3) than January 2021 (4.9; 95% CI: 4.9 to 5.0). Vaccinated admission rates were ≤1 per 100,000 from February to December. Doses 1 and 2 VE waned over time, particularly in older and clinically vulnerable groups (although this may reflect that they were vaccinated earlier). Dose 3 VE remained above 93%. CONCLUSIONS: COVID-19 hospitalisations were consistently highest in the unvaccinated. Despite high case rates at the end of 2021, overall admission rates remained stable, driven by low admission rates among vaccinated people. There is population-level waning in VE, recovering after subsequent doses, potentially more marked in older and at-risk groups. The findings support JCVI (Joint Committee on Vaccination and Immunisation) guidance for an ongoing booster programme, especially in older people and higher clinical risk groups.

BACKGROUND: International evidence shows that severe paediatric obesity results in an increased risk of ill health and may require specialised weight management strategies, yet there remains a lack of data on the extent of the problem. OBJECTIVE: To examine the prevalence of severe obesity in children aged 4-5 and 10-11 years, attending English schools between 2006/2007 and 2012/2013. DESIGN: A retrospective analysis of National Child Measurement Programme (NCMP) data. SETTING: Maintained schools in England. PARTICIPANTS: All children aged 4-5 and 10-11 years included in the NCMP dataset. MAIN OUTCOME MEASURES: Prevalence of severe childhood obesity, defined using the 99.6th centile of the British 1990 (UK90) growth reference for body mass index (BMI), analysed by sex, geography, ethnic group and deprivation. RESULTS: The key findings show that in 2012/2013, severe obesity (BMI ≥UK90 99.6th centile) was found in 1.9% of girls and 2.3% of boys aged 4-5 years, and 2.9% of girls and 3.9% of boys aged 10-11 years. Severe obesity prevalence varies geographically and is more prevalent in children from deprived areas, and among those from black ethnic groups. CONCLUSIONS: The findings from this study should help to raise awareness of the prevalence of severe obesity and support the provision of adequate treatment and prevention services both to support children who are already severely obese and reduce the prevalence of extreme weight in the future.

The promotion of cycling and walking for everyday physical activity not only promotes health but can also have positive effects on the environment. This booklet summarizes the tools and guidance developed to facilitate this shift: the methodology for the economic assessment of transport infrastructure and policies in relation to the health effects of walking and cycling; systematic reviews of the economic and health literature; and guidance on applying the health economic assessment tools and the principles underlying it. This methodology and user guide will be of key interest to professionals at both national and local levels: transport planners, traffic engineers, and special interest groups working on transport, walking, cycling or the environment, as well as health economists, physical activity experts and health promotion experts.

Increasing regular physical activity is a key public health goal. One strategy is to change the physical environment to encourage walking and cycling, requiring partnerships with the transport and urban planning sectors. Economic evaluation is an important factor in the decision to fund any new transport scheme, but techniques for assessing the economic value of the health benefits of cycling and walking have tended to be less sophisticated than the approaches used for assessing other benefits. This study aimed to produce a practical tool for estimating the economic impact of reduced mortality due to increased cycling. The tool was intended to be transparent, easy to use, reliable, and based on conservative assumptions and default values, which can be used in the absence of local data. It addressed the question: For a given volume of cycling within a defined population, what is the economic value of the health benefits? The authors used published estimates of relative risk of all-cause mortality among regular cyclists and applied these to levels of cycling defined by the user to produce an estimate of the number of deaths potentially averted because of regular cycling. The tool then calculates the economic value of the deaths averted using the "value of a statistical life." The outputs of the tool support decision making on cycle infrastructure or policies, or can be used as part of an integrated economic appraisal. The tool's unique contribution is that it takes a public health approach to a transport problem, addresses it in epidemiologic terms, and places the results back into the transport context. Examples of its use include its adoption by the English and Swedish departments of transport as the recommended methodologic approach for estimating the health impact of walking and cycling.

Die Förderung von Radfahren und Zufußgehen zum Zwecke täglicher körperlicher Betätigung kommt nicht nur der Gesundheit zugute, sondern kann sich auch positiv auf die Umwelt auswirken. In dieser Broschüre werden die für die Erleichterung einer solchen Umstellung entwickelten Instrumente und Empfehlungen zusammengefasst: die Methodik für die ökonomische Bewertung der Verkehrsinfrastruktur und der Verkehrspolitik in Bezug auf die gesundheitlichen Effekte von Zufußgehen und Radfahren; systematische Sichtungen der ökonomischen und gesundheitsbezogenen Fachliteratur; und Empfehlungen für die Anwendung der gesundheitsökonomischen Bewertungsinstrumente und der ihnen zugrunde liegenden Prinzipien. Die Methodik und das Benutzerhandbuch sind von wesentlichem Interesse für Fachkräfte auf nationaler wie kommunaler Ebene, d. h. Verkehrsplaner und Verkehrsingenieure sowie Interessengruppen in den Bereichen Verkehr, Zufußgehen, Radfahren oder Umwelt, aber auch Gesundheitsökonomen und Experten für Bewegung und Gesundheitsförderung.

STUDY OBJECTIVE: The drive to tackle health inequalities at the local level has increased interest in mortality data for small populations. There is some concern that nursing homes may affect measures of mortality for small populations, but there has been little in depth analysis of this. DESIGN AND SETTING: Deaths between 1997 and 2001 and population figures from the GP register (Exeter) database and census 2001 were used to produce life expectancy (LE) figures for all electoral wards in West Sussex. The proportion of those dying within each ward that had been residents of nursing homes was calculated and the relation between these variables and deprivation investigated. RESULTS: There was a significant linear relation between nursing home deaths and LE (p<0.0001), which explained 36% of variation in LE between wards. Deprivation accounted for around 35% of the variation in LE (p<0.0001) but was not correlated with nursing home deaths (p> or =0.0982). Multiple linear regression shows that over 60% of the variation in LE at ward level can be explained by both nursing home deaths and deprivation (p<0.0001) and that the two variables explain similar proportions of this variation. The relation between LE and nursing home deaths within wards grouped by deprivation suggests that the impact of nursing homes is strongest in deprived wards. CONCLUSIONS: This finding has important implications for LE calculations in small populations. Further investigation is now needed to examine the impact of nursing homes in other areas, on other mortality measures, and in larger populations.
