An international report led by the University of Cambridge (United Kingdom) warns that there is a serious risk of a ‘lost’ generation emerging in Gaza, due to the combination of educational, physical and psychological impacts after more than two years of the Israeli invasion. As of 1 October 2025, the UN Office for the Coordination of Humanitarian Affairs (OCHA) reported the deaths of 18,069 students and 780 education personnel in Gaza, with 26,391 students and 3,211 teachers injured. The study estimates that children in Gaza will have lost the equivalent of five years of education due to repeated school closures since 2020, first due to COVID-19 and then due to the Israeli invasion.

A team from the United States has analyzed nearly twenty studies on melatonin use in children between the ages of 0 and 6 in different countries. Although it appears that melatonin can help improve sleep onset in children with neurological conditions such as autism spectrum disorders, the data indicate that in recent years there has been an increase in sales of these products without a clear understanding of their actual effectiveness and potential long-term consequences for typically developing young children. The results are published in JAMA Network Open. 

An international team has analyzed data from nearly 60 studies involving more than 48,000 children with different types of diets and compared the nutritional profile and various health parameters between those following vegan, lacto-ovo-vegetarian, and omnivorous diets. The results indicate that plant-based diets, if well-planned, can promote healthy growth with benefits such as a better cardiovascular profile and lower cholesterol levels. However, they may have difficulty achieving adequate levels of vitamins D and B12, calcium, iron, and zinc. According to the authors, the findings underscore the need for careful planning and supplementation in children following these types of diets. The study is published in Critical Reviews in Food Science and Nutrition. 

Severe combined immunodeficiency due to ADA enzyme deficiency is a rare disease that, without treatment, usually causes death within the first two years of life. These "bubble children" are currently treated with a bone marrow transplant or with injections that aim to restore, to the extent possible, the function of this enzyme. Now, an international team presents the results of a gene therapy administered to 62 children with the disease between 2012 and 2019. The therapy was effective in 95% of cases and did not cause serious complications, according to the authors, whose work is published in the journal NEJM. 

The temporary employment rate for teaching staff in Spain is 31%, above the OECD average of 19% and the EU average of 17%. This is one of the results of the latest edition of TALIS, the Teaching and Learning International Study, promoted by the OECD and involving more than 50 participating countries. In its previous edition, in 2018, 33% of Spanish teachers had temporary contracts. The study also shows that teacher job satisfaction is among the highest, at 95%—compared to 89% in the OECD and 90% in the EU. As a new feature, TALIS analyzes four new areas: the impact of artificial intelligence on learning and teaching, managing diversity in the classroom, socio-emotional learning, and education for sustainability.

People with autism have different genetic and developmental profiles depending on the age at which they were diagnosed, according to a study published in Nature. The authors distinguish two groups: the first receive a diagnosis of autism in early childhood, with lower social and communication skills and a moderate correlation with attention deficit hyperactivity disorder (ADHD) and mental health disorders. The other group of people receive their diagnosis in adolescence, with increased socio-emotional and behavioural difficulties, and higher genetic correlations with ADHD and mental health disorders. 

A new school year has begun, and pollution, which exceeds recommended limits in many urban centres, will once again affect children and their families. What consequences could this have on health? How does climate change affect it? What solutions can be implemented? SMC Spain organised an informative session with Julio Díaz and Cristina Linares to answer these questions.

An international team has analyzed data from 17 studies in 10 countries involving more than 9,000 participants and concluded that childhood obesity prevention programs focused on mothers and fathers do not appear to have an impact on young children. According to the authors, who published their findings in The Lancet, broader, coordinated, and well-resourced public health actions are needed.

A diet rich in omega-3 fatty acids, found mainly in fish oils, may help prevent the development of myopia in children, while high consumption of saturated fats, found in foods such as butter, palm oil and red meat, may increase the risk of developing this condition, according to research published in the British Journal of Ophthalmology. The study was conducted on a thousand children in Hong Kong aged between six and eight.

Between 1980 and 2023, childhood vaccination rates against diphtheria, tetanus, whooping cough, measles, polio and tuberculosis doubled worldwide, according to a study published in The Lancet. However, this increase slowed in many countries between 2010 and 2019; during this period, measles vaccination declined in half of all countries.
