Nearly one in five women and one in seven men have experienced sexual violence before the age of 18 worldwide

Research published in The Lancet estimates that 18.9% of women and 14.8% of men worldwide experienced sexual violence before the age of 18.

The authors highlight the difficulty of distinguishing whether these variations are due to real differences or to unequal levels of reporting. In Spain, the figures obtained in this systematic review are 10.8% for girls and 12.2% for boys.

Banning tobacco among young people would prevent more than a million deaths from lung cancer

If lifetime tobacco consumption were banned among young people currently aged 14 to 18, 1,200,000 lung cancer deaths worldwide could be prevented in the future, according to a study with Spanish involvement published in the journal The Lancet Public Health. The greatest impact would occur in low- and middle-income countries, but in higher-income regions, more than 60% of lung cancer deaths in that age group would also be avoided.
