Individual-level interventions to reduce personal exposure to outdoor air pollution and their effects on long-term respiratory conditions

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: 1. To assess the efficacy, safety and acceptability of individual‐level interventions that aim to help people with or without chronic respiratory conditions to reduce their exposure to outdoor air pollution. 2. To assess the efficacy, safety and acceptability of individual‐level interventions that aim to help people with chronic respiratory condition reduce the personal impact of outdoor air pollution and improve health outcomes.
