Reactions to the obesity map in child and adult populations in Spain

In Spain, both in the child and adult populations, excess weight and obesity are more prevalent among men. Additionally, lower educational levels, lower income, disability, and the presence of individuals with obesity in the household are factors associated with a higher prevalence of excess weight and obesity. These are some of the conclusions drawn from two scientific articles and two complementary reports prepared by the National Center for Epidemiology of the Carlos III Health Institute and the Spanish Agency for Food Safety and Nutrition (AESAN). The data is derived from the ENE-COVID survey, which investigated the seroprevalence of COVID-19 infection in Spain.

Reactions: study links living as a renter to faster biological ageing

Living as a private renter is associated with faster biological ageing than owning a home, according to a study using a UK database with data available on 1,420 people. The team, whose research is published in the Journal of Epidemiology and Community Health, used DNA methylation data - chemical modifications - to measure people's biological age, and says this correlation is stronger than the association between biological ageing and unemployment, or having been a smoker. Apart from blood samples from the database, the research also used historical data from a national survey.

Reactions: record heat in summer 2022 caused more than 61,000 deaths in Europe, more than 11,000 of them in Spain

The heat waves that took place in Europe during the summer of 2022 were associated with more than 61,000 deaths on the continent, more than 11,000 of them in Spain. These are the results of a modelling study published in the journal Nature Medicine and led by ISGlobal researchers.

Reactions: exposure to urban green spaces is associated with slower epigenetic ageing

Living near green spaces over a long period of time is associated with better health, an association more marked in women and white people than in men and black people, according to a study conducted in four US cities. The analysis concludes that exposure to urban green space between 1985 and 2006 is associated with slower epigenetic ageing, and that this association is stronger in disadvantaged neighbourhoods. The international team publishing this paper in Science Advances includes a researcher from ISGlobal in Barcelona.

Reaction: mortality increased by 20 % in the summer months of 2022 compared to 2019 due to heat, among other causes

From May to August 2022, 157,580 deaths were recorded, 20.5% more than in the same months of 2019, before covid. This increase in mortality was mainly among people aged 75 years and older. Of the causes of death directly related to the heat, heat stroke and dehydration stood out. These are some of the provisional data published by the National Statistics Institute (INE) in relation to deaths in 2022. Covid-19 was the most frequent cause of death, with 31,559 people dying, 20% less than in 2021.

Reaction to study associating lung infections in infancy with increased risk of death from respiratory disease in adulthood

People who had a lower respiratory tract infection—such as bronchitis or pneumonia—before the age of two have twice the risk of premature death from respiratory disease in adulthood, according to a study published in The Lancet. The research is based on long-term data from over 3,500 people born from 1946 onwards in England, Scotland and Wales. According to the study, one in five premature deaths in this representative sample could be due to respiratory infections. The team adjusted their estimate by taking into account factors such as socioeconomic status in childhood and smoking in adulthood.
