Risk assessment of occupational skin cancer among outdoor workers in southern Spain: local pilot study

OBJECTIVE

Overexposure to ultraviolet (UV) radiation is the main preventable cause of skin cancer. Outdoor workers, exposed to the sun for many hours throughout their working lives, are at special risk. The aim of this study is to determine occupational photoexposure and photoprotection among outdoor workers employed by a municipality in southern Spain.

METHODS

Cross-sectional descriptive study focusing on outdoor workers employed by the municipality of Fuengirola (in areas such as construction, gardening, urban cleaning and beach maintenance). The participants were monitored by personal dosimetry, participated in a dermatological check-up and answered a validated questionnaire (CHACES) on their habits, attitudes and knowledge related to sun exposure.

RESULTS

The median effective erythema dose of exposure to solar UV radiation during the working day (n=20) was 379.4 J/m², equivalent to 3.8 standard erythema doses, almost 3 times higher than the recommended limits for an 8-hour workday. Skin examination (n=128) revealed the presence of actinic lentigines (79.7%), actinic keratoses (8.6%) and skin cancer (3.9%). The CHACES questionnaire (n=128) revealed a sunburn rate of 50.0%. Photoprotection practices were markedly deficient: only 16.7% of the survey respondents sought protection in the shade, 20.3% avoided exposure during the peak exposure hours and 33.1% applied sunscreen.

CONCLUSIONS

This is the first study to evaluate UV radiation exposure, occupational sun protection practices, sunburn and actinic injuries of different outdoor workers in one of the sunniest regions of Spain and underlines the need for effective interventions to protect outdoor workers' health.

Teachers' knowledge about type 1 diabetes in south of Spain public schools

AIMS

To evaluate the knowledge of teachers in educative public centres (pre-, primary, and secondary schools) about type 1 diabetes (T1D) in the Puerto Real University Hospital area (Cadiz, Spain).

METHODS

Descriptive observational study in which 756 teachers' answers on the Test of Diabetes Knowledge for Teachers (TDKT) were analysed. Teachers from 44 educative public centres in the Puerto Real University Hospital area (Cadiz, Spain) were selected by randomized sampling (mean age, 44.3 ± 8 years; 61.7% women).

RESULTS

Although 43.2% survey respondents recognised having had or currently having children or adolescent students with T1D, most demonstrated they did not have enough knowledge about T1D (mean score, 6.0 ± 4.3 points from a maximum of 16), and only 5.1% had sufficient knowledge (13-16 points) to be an effective support person to students with diabetes in school. However, the vast majority of survey respondents correctly answered questions about symptoms (74.2%) and hypoglycaemia treatment (85.9%). Univariate analysis of factors associated with teachers' knowledge about diabetes revealed that teachers with ≤ 15 years of teaching experience and physical education teachers had better knowledge than their co-workers.

CONCLUSIONS

It is necessary to improve teachers' knowledge about diabetes in our health area with the aim of improving the security of children and adolescent students with T1D in school centres.
