Every 1% increase in the proportion of useable or total greenspace was associated with a 4% lower anxiety/mood disorder treatment. Distance to nearest useable greenspace was also associated with anxiety/mood disorder treatment. The authors found 3% lower anxiety/mood disorder treatment for every 100 m decrease in distance to the nearest useable greenspace. Anxiety/mood disorder treatment counts were associated with three greenspace measures. The proportion of both total and useable greenspace within 3 km and distance to nearest useablegreenspace all indicated a protective effect of increased access to greenspace against anxiety/mood disorder treatment counts. Access to total and useable greenspace within 300 m did not exhibit significant associations.
