Regularly protected was defined as those reporting Regular (60–80% of the time) use of at least one of the recommended ways to protect from the sun (i.e. Sunscreen SPF 15+, Clothes, Shade or Avoidance of midday sun), and Consistently protected were defined as those reporting Always (90–100%) using at least one of the recommended ways to protect from the sun (i.e. Sunscreen SPF 15+, Clothes, Shade or Avoidance of midday sun).
