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.
A meta-analysis by the University of Valencia has studied the links between leisure reading habits on digital devices and the reading comprehension of students of different ages. The research - which is based on 25 studies published between 2000 and 2022 involving some 470,000 students from different countries - concludes that in the early stages (primary and 1st and 2nd ESO in the Spanish case) there were small negative relationships between digital leisure reading and reading comprehension, while in later stages (3rd and 4th ESO, baccalaureate and university) the relationship became slightly positive. The research is published in Review of Educational Research.
Intimate partner violence is associated with an increased risk of depression and miscarriage, according to a systematic review of the scientific literature published since 1970. Sexual abuse in childhood is associated with an increased risk of alcohol use disorder and self-harm, says the study published in Nature Medicine. According to its authors, this analysis of 229 previous studies reveals that intimate partner violence and childhood sexual abuse have a more extensive impact on health than previously described.
