Skin Cancer: Interventions in Outdoor Occupational Settings

Summary of CPSTF Finding

The Community Preventive Services Task Force (CPSTF) recommends interventions in outdoor occupational settings to prevent skin cancer based on strong evidence of effectiveness in increasing outdoor workers’ sun protective behaviors (e.g., use of sunscreen or sun protective clothing or combination of sun protective behaviors) and reducing sunburns.


Interventions in outdoor occupational settings to promote sun protective behaviors among workers include at least one of the following:
  • Educational approaches (e.g., providing informational messages about sun protection to workers through instruction, small media such as posters or brochures, or both)
  • Activities designed to influence knowledge, attitudes, or behavior of workers (e.g., modeling or demonstrating behaviors)
  • Environmental approaches to encourage sun protection (e.g., providing sunscreen or shade)
  • Policies to support sun protection practices (e.g., requiring sun protective clothing)

About The Systematic Review

The CPSTF finding is based on evidence from a Community Guide systematic review published in 2004 (Saraiya et al., 7 studies with behavioral outcomes; search period January 1966 June 2000) combined with more recent evidence (8 studies, search period June 2000 April 2013). The systematic review was conducted on behalf of the CPSTF by a team of specialists in systematic review methods, and in research, practice, and policy related to preventing skin cancer. This finding updates and replaces the 2002 Task Force finding on Education and Policy Approaches in Outdoor Occupational Settings..

Summary of Results

Updated Evidence (search period June 2000 – April 2013)

Included studies (8 studies, 11 study arms) evaluated intervention effects on various measures of sun protection behaviors and on physiological consequences of UV radiation exposure among outdoor workers. Results were generally favorable across outcomes.

  • Sunscreen use
    • Median increase of 8.0 percentage points (range: 7.0 to 10.1 percentage points; 3 studies)
    • Other measures of sunscreen use also showed favorable results (1 study)
  • Hat use
    • Median increase of 8.8 percentage points (range: 4.8 to 11.0 percentage points; 4 studies)
    • Other measures of hat use also showed favorable results (1 study)
  • Clothing use
    • Increases of 23.4 and 52.0 percentage points (2 studies)
    • Other measures of clothing use also showed favorable results (1 study)
  • Combined sun-protective behaviors
    • Several measures of combined sun-protection behaviors showed favorable results (4 studies, 7 study arms)
  • Sunburn incidence
    • Median decrease of 5.2 percentage points in the number of sunburn episodes (range: 7.0 to 3.0 percentage points; 3 studies)
    • Other measures of decrease in sunburns showed favorable results (1 study)
  • Included studies also showed favorable effects of the intervention on the incidence of solar keratosis (1 study) and skin cancer (1 study).

Unfavorable or mixed results were found for the following outcomes.

  • Shade seeking behavior among outdoor workers (1 study)
  • UV radiation exposure measured as a change in skin pigmentation (2 studies)

Previous Review (search period January 1966-June 2000)

Results from 7 studies of behavioral outcomes found favorable results for sunscreen use (2 studies), hat use (1 study), protective clothing use (2 studies), shade use (1 study), sun exposure (1 study), composite sun protective behaviors (1 study), and number of sunburns (1 study).

Summary of Economic Evidence

An economic review of this intervention was not conducted.


Based on the settings and populations from included studies, results are applicable to the following:
  • Workers of all ages
  • People who are white (applicability to other groups is unclear)
  • Full-time and seasonal workers
  • Recreational and non-recreational outdoor settings

Evidence Gaps

The CPSTF identified several areas that have limited information. Additional research and evaluation could help fill remaining gaps in the evidence base. (What are evidence gaps?)

Large, multi-arm studies, in diverse occupational settings are needed to assess comparative effectiveness by specific intervention components in specific context and settings.

  • Limited evidence is available on the following:
    • Interventions with worksite policy components
    • Interventions targeting non-White outdoor workers
    • Interventions that target outdoor workers in non-recreational occupational settings
    • Interventions to evaluate health outcomes (e.g., new cases of skin cancers)
    • Studies with longer follow-up times would provide useful information about the sustainability of intervention effects and also account for seasonal variations.

Study Characteristics

  • Most studies were randomized control trials conducted in the United States.
  • Most studies combined educational and environmental interventions.
  • 50% of the studies were conducted in recreational settings.
  • One study was implemented as part of a mandatory worksite policy.
  • All studies assessed sun protective behaviors; half assessed sunburns, and one study also assessed solar keratosis and number of skin cancers.

Analytic Framework

Effectiveness Review

Analytic Framework

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

Search Strategies

This literature search was performed to provide a systematic review of the evidence to the Guide to Community Preventive Services and update previous reviews of the literature on skin cancer prevention methods (Saraiya et al., 2004).

Effectiveness Review

The updated search applied a slightly broader search strategy than was used in the Saraiya et al. reviews. Three bibliographic databases were searched: MEDLINE, CINAHL, and PsycINFO. The databases searched covered publications in biomedical and behavioral sciences. The types of documents searched in the databases included journal articles, books, book chapters, reports, conference papers, and dissertations.

Search strategies were adjusted to each database, based on controlled and uncontrolled vocabularies and search software. In addition, the bibliographies of all reviewed articles were used to identify any further literature.

The search period was from June, 2000 – May, 2011 for the following updated reviews, though the search was extended to include items published earlier if they had been added to the databases since the last search was performed.

  • Mass media
  • Multicomponent community-wide interventions
  • Childcare center-based interventions
  • High school- and college-based interventions
  • Primary and middle school interventions

The search period was from 2011 – 2013 for the following updated reviews, though the search was extended to include items published earlier if they had been added to the databases since the last search was performed.

  • Outdoor occupational settings
  • Outdoor recreational and tourism settings

Once the literature search was completed, Community Guide staff reviewed the citations using the following inclusion and exclusion criteria to narrow down the publications to be reviewed.

Considerations for Implementation

The following considerations are drawn from studies included in the evidence review, the broader literature, and expert opinion. The Community Guide does not conduct systematic reviews of implementation.
  • Employers should consider worker safety when implementing sun protection interventions.
  • Employers can provide sun safety supports such as shade structures, sun protective clothing, and sunscreen.
