In the context of World AIDS Day, which is celebrated on 1 December, it is essential to reflect on one of the most urgent challenges in the fight against this disease: HIV in the paediatric population. A project led by the Complutense University of Madrid seeks to reduce paediatric mortality by training research leaders in sub-Saharan Africa and applying technology and innovation.
An analysis of the gut microbiota of children growing up on farms or with pets shows that early establishment of anaerobic commensal bacteria is associated with lower rates of allergy later in life. The study, which used data from 65 children aged between three days and 18 months, is published in the journal PLOS ONE.
The restriction of sugar during the first 1,000 days of life, starting from gestation, may protect against diabetes and hypertension in adulthood, according to a study published in Science. The research uses data from sugar rationing implemented in the United Kingdom after World War II. The findings highlight the long-term benefits of reduced sugar intake during early development.
Global childhood immunisation coverage stagnated in 2023, with 2.7 million more children unvaccinated or under-vaccinated than at pre-pandemic levels in 2019. This is one of the data published by the World Health Organization (WHO) and UNICEF in the World Health Organization's Worldwide Estimates of National Immunisation Coverage (WUENIC), which captures global vaccination trends against 14 diseases. More than half of unvaccinated children live in 31 countries with fragile and conflict-affected environments.
Both sex and gender are associated with distinct networks in the brains of boys and girls, according to an analysis of brain images of 4,757 children in the US. Understanding these neurobiological patterns is important for identifying how sex and gender influence health and for developing specific diagnostic tools, the research team writes in Science Advances.
A study published in the journal PLOS ONE, which includes data from over 3,000 Spanish adolescents and children, has shown that those living in more walkable areas report spending more minutes per day engaging in active transportation compared to those from less walkable neighborhoods. Along those lines, the lowest average minutes spent playing outdoors are observed among participants from neighborhoods with lower socioeconomic status and less walkability. The research is part of the PASOS study, coordinated by the Gasol Foundation.
Research involving more than 3,000 adolescents and children from all Spanish autonomous communities concludes that those living in less walkable neighbourhoods with lower socioeconomic status walk less and engage in less physical activity at weekends than those living in more walkable areas with higher socioeconomic status. The paper, published in the journal PLOS ONE and part of the PASOS study, was presented by two of its authors at a briefing organised by SMC Spain.
Children born in October are more likely to be vaccinated against flu during that month and less likely to be diagnosed with the disease than those born in other months, according to a study published in BMJ. The research involved more than 800,000 US children aged two to five years who were vaccinated against the flu between 1 August and 31 January in the period from 2011 to 2018. The results suggest that the month of birth is related to both the timing of flu vaccination and the likelihood of flu diagnosis, and that October is the best month for flu vaccination.
Dressing in school uniform is associated with less physical activity in children, especially primary school girls, according to a study by the University of Cambridge (UK) published in the Journal of Sport and Health Science. The study analysed data on the physical activity levels of more than one million children aged 5-17 in 135 countries, including Spain, combined with an online survey.
The largest meta-analysis to date that studies the risk of children of people with a mental disorder also suffering from some type of mental disorder during their lifetime has been published, with Spanish participation. According to the study, the risk is more than double that of the rest of the population. To explain the study and resolve any doubts that may arise, the Science Media Centre Spain organised an information session with one of the authors, psychiatrist Joaquim Raduà.
