Personen, die als Kinder (0–17 Jahre) der Raumluftverschmutzung durch feste Brennstoffe ausgesetzt waren, schnitten im Erwachsenenalter (45+ Jahre) bei kognitiven Tests deutlich schlechter ab; wobei Männer, Raucher und regelmäßige Alkoholkonsumenten besonders anfällig für diesen Effekt sind

> the study is the first to investigate how early-childhood exposure to indoor air pollution affects cognitive performance in adulthood. It analysed nationally representative data from over 7,000 Chinese adults aged 45, using advanced machine learning techniques

>Among biological mechanisms, overweight and limitations in daily activities were highlighted, suggesting that early exposure may harm long-term physical health and indirectly impact brain function.
>
>In terms of socioeconomic mechanisms, childhood exposure to air pollution was associated with lower levels of education and income in adulthood, both of which are known risk factors for cognitive decline.

> Men, smokers and regular alcohol users were particularly vulnerable to the detrimental effects of early exposure to indoor air pollution on cognitive performance. The results are consistent with the idea that inflammation and stress – often exacerbated by tobacco or alcohol use – may amplify the neurological damage caused by air pollution.
