Background: Previous research suggests an association between exposure to nature and improved attention. However, no observational studies explored the underlying mechanisms or considered bluespace, and none used Polish data. We investigated the association between exposure to nature and attention, and whether it was mediated by nature perception, physical activity and sleep duration. Methods: Data derived from the case-control NeuroSmog study comprised 195 participants with attention deficit hyperactivity disorder (ADHD) and 457 participants without ADHD, all aged 10 to 13. Attention was evaluated using the computerized attention network test and the continuous performance test. Lifelong and current exposure to nature, determined by percentage of grass and tree cover and water presence within 500m buffer around residences, as well as domestic garden, were examined through linear, log-linear and negative binomial regressions. Potential pathways were explored using structural equation modelling. Results: Participants with ADHD with higher exposure to tree cover tended to have improved orienting ability, shorter reaction time and fewer correct rejections, while participants without ADHD tended to show decreased alertness and improved orienting ability. Participants with ADHD with higher exposure to grass cover tended to have longer reaction time, decreased alertness, improved orienting ability, reduced target discrimination ability, fewer correct rejections and less risky response style, while participants without ADHD tended to show decreased orienting ability, more mistakes, longer reaction time, better hit rate and more risky response style. Participants without ADHD with water in their neighbourhood tended to have improved orienting ability, fewer mistakes and better hit rate. Participants without ADHD with a garden tended to show improved target discrimination ability, better hit rate and more risky response style. No mediating pathways were revealed. Conclusion: Tree cover and presence of garden and water tended to be associated with improved attention in Polish adolescents while grass tended to have negative impact.
