*Numbers may not sum to overall totals owing to missing data; two men had missing data for skin sensitivity, and seven men had missing data for number of sunburns; two women had missing data for number of sunburns; these participants were excluded from further analyses.
†Defined as reaction to one hour of sun exposure first time in summer.
