These findings suggest that zinc is more important for taste acuity in males than females and indicate the importance of taking sex differences into account when studying taste acuity.

Aim To investigate female university students' knowledge, attitudes, and behaviours towards sun exposure and the use of artificial tanning devices. Subject and methods A descriptive correlational survey design using online questionnaires, targeting a population of female university students aged 18-25 from one university in the United Kingdom. Results Three hundred and thirty-five students participated (response rate = 26.4%). Students demonstrated average knowledge and good attitude to tanning behaviours, but neither were statistically significantly associated with tanning behaviours. Students showed a history of substantial tanning behaviours, including the use of sunbeds, primarily because having a tanned skin made them look good and thus feel better. Conclusion This study has reaffirmed that there is no simple correlation between individuals' knowledge and attitudes and subsequent sun-tanning behaviours. Feeling good and looking good are critical attributes to female university students' self-esteem, and these values and beliefs outweigh risk perception of sun-tanning behaviours, and female university students continue to engage in risky tanning behaviours. Focused health promotion activities by public health authorities and higher education institutions should target students' principal belief of looking good feeling good, as such targeted health promotion may reduce harmful sun tanning behaviours and ultimately mitigate the rising incidence in skin cancers.
