Experimental: Shade Sail
Shade sails were constructed over passive recreation areas in public parks between pretest and posttest. Shade sails maximized available shade in the passive recreation areas from 11 am to 3 pm in the summer.
Behavioral: Shade Sail
Shade sails had powder-coated or gout galvanized steel poles and a lighter colored shade cloth to transmit visual light. The shade cloth met Ultraviolet Protection Factor (UPF) ratings to reduce UV under the shade cloth by 94%. The final shade sail designs and sizes were determined with input from parks department staff and complied with all local engineering, building, and planning codes. Shade sails exceeded the minimum safety requirements for strength (for wind and snow load), resistance to light degradation, and UV transmission. The design minimized climbing access points and hazards to adjacent activities.
No Intervention: Unshaded Control
Passive recreation areas in public parks that remained unshaded at pretest and posttest.
- Observed Use of Passive Recreation Area by Adults [ Time Frame: One-year ]Any use of each passive recreation, assessed by observing each passive recreation areas for 30 minutes on four weekend days between 11 am and 3 pm when forecast high temperatures were had forecast high temperature were between 72°F/22°C and 95°F/35°C over a 20-week period during two summers (pretest summer, posttest summer) by trained research assistants. Observations were suspended during rain.
- Solar Ultraviolet Radiation Level [ Time Frame: One-year ]Average potential UV exposure for a user of the passive recreation area assessed in standard erythemal units, based on measurements from a handheld UV meter performed by trained research assistants during assessment of the primary outcome.
