Implementation of educational interventions among operating engineers (heavy equipment operators) in Michigan significantly increased the use of sunscreen and decreased the number of reported sunburns. The objectives were to determine changes in sunscreen use and sunburning among Operating Engineers randomized to four conditions in the Sun Solutions study: The study was published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.
Rates Of Melanoma
The rates of melanoma have been increasing in recent decades in the United States, and outdoor workers are at an increased risk for developing this deadliest form of skin cancer. They wanted to investigate how behavioral interventions can affect sunscreen use and sunburning among operating engineers as a way to prevent skin cancer.
While prior studies have indicated that interventions can result in beneficial sun-safety behaviors among outdoor workers, a systematic analysis revealed that this population had inadequate sun-protective behaviors.
Furthermore, in a previous analysis, they found that approximately two-thirds of operating engineers reported rarely or never wearing sunscreen, even though 80% of this population reported spending four to five hours per day in the sun during summer work hours. The use of sunscreen and protective clothing can mitigate exposure to UV radiation and decrease the risk of developing skin cancer.
Participants were provided baseline survey with and were randomized to four interventions: education only; education and text message reminders; education and mailed sunscreen; and education, text message reminders, and mailed sunscreen. Following the summer intervention, 82.1% of participants responded to post-intervention surveys.
Sun Protection For Skin
Key topics included current use of sun protection in this population as identified in a prior survey, the incidence and prevalence of skin cancer among outdoor workers, skin cancer risk factors and types of skin cancer, and methods to prevent sunburning.
Overall, the percentage of participants who reported never wearing sunscreen was 38.1% at baseline and decreased to 21.8% at follow-up. All four interventions resulted in the significantly increased use of sunscreen, with a marginally significant increase among participants who received the intervention comprised of education and text message reminders.
Overall, the percentage of participants who reported burning at least four times during the summer decreased from 18.6% at baseline to 5.8% at follow-up. The number of reported sunburns decreased significantly across all intervention groups. However, there was no significant difference in reported sunburns among the four interventions.
Our most important finding was that a simple educational intervention significantly decreased the number of sunburns in operational engineers.
Limitations of the study include a reliance on self-reported data. Additionally, nearly half of participants who received text messaging opted out of this service; the authors hypothesize that the high opt-out rate was due to the perceived cost of text messaging fees.
