#4Corners4Health Social Media Cancer Prevention Campaign for Emerging Adults: Protocol for a Randomized Stepped-Wedge Trial

#4Corners4Health Social Media Cancer Prevention Campaign for Emerging Adults: Protocol for a Randomized Stepped-Wedge Trial

The primary outcomes measured at all assessment times will be MVPA, healthy eating patterns, nicotine product use, alcohol intake, sunburn, and HPV vaccination. The social media campaign will be conducted over 12 months in 4 separate Facebook private groups. The intervention will start in each cohort at successive 13-week intervals, so cohorts will receive varying doses of campaign exposure (ie, 180 posts per 13-week interval) via stepped entry.

Hell’s Itch: A Unique Reaction to UV Exposure

Hell’s Itch: A Unique Reaction to UV Exposure

Patient accounts like this distinguish Hell’s Itch from a typical sunburn. One in 3 people in the United States experience a sunburn annually [1]. Sunburn is characterized by cutaneous erythema appearing 24 to 72 hours following sun exposure. The cause of sunburn is excessive exposure to UV radiation, commonly causing acute, transient inflammation in the skin [2]. Symptoms depend on sunburn severity and may include blistering, peeling, and pruritus due to peeling [2].

The Comparison of Sun Protection Factor 30 Persistence Between Inorganic and Organic Sunscreen in Swimmers: Double-blind Randomized Clinical Trial

The Comparison of Sun Protection Factor 30 Persistence Between Inorganic and Organic Sunscreen in Swimmers: Double-blind Randomized Clinical Trial

These exposures can cause various skin disorders such as sunburn [3,4]. For sunburn prevention, protection from the sun is needed and can be achieved in several ways, one of which is by using sunscreen [5,6]. There are two types of sunscreens based on their filters, specifically, organic and inorganic. Organic sunscreen absorbs and prevents UV light from entering the epidermis. Meanwhile, inorganic sunscreen works by reflecting and scattering radiation [5,7,8].

Assessing Sunscreen Protection Using UV Photography: Descriptive Study

Assessing Sunscreen Protection Using UV Photography: Descriptive Study

Sunlight or UV radiation is the main risk factor for skin cancers, and sunburn remains highly prevalent in the northern Australian state of Queensland, with 49% of adults and 45% of children sunburnt in the previous 12 months [8]. Of the children who were sunburnt in the past 12 months, 69% were most recently sunburnt during a water-based activity [8]. These findings are concerning and highlight the importance of adequate sunscreen coverage and reapplication when participating in water-based activities.

Real-Time UV Measurement With a Sun Protection System for Warning Young Adults About Sunburn: Prospective Cohort Study

Real-Time UV Measurement With a Sun Protection System for Warning Young Adults About Sunburn: Prospective Cohort Study

Initially, participants selected their skin type based on their perceived sun sensitivity to sunburn, which corresponded to skin type I, II, or III. The minimal erythema dose (MED) for skin type I, II, and III is 200 J/m2, 250 J/m2, and 300 J/m2, respectively [17]. Thus, a sunburn line was established for each participant according to their self-reported skin type (Figure 2). Sunburn was defined as only just perceptible reddening of the skin (pink) at 24 hours after UV exposure [18].

Testing Wearable UV Sensors to Improve Sun Protection in Young Adults at an Outdoor Festival: Field Study

Testing Wearable UV Sensors to Improve Sun Protection in Young Adults at an Outdoor Festival: Field Study

Sunburn remains highly prevalent in Australia in the younger age groups, and as little as one severe sunburn in childhood can double the risk of developing a melanoma before the age of 40 years [6,7]. Australian adolescents continue to report high-risk behaviors such as spending long periods of time in the sun and positive views of tanning [8].

A Mobile Technology Intervention With Ultraviolet Radiation Dosimeters and Smartphone Apps for Skin Cancer Prevention in Young Adults: Randomized Controlled Trial

A Mobile Technology Intervention With Ultraviolet Radiation Dosimeters and Smartphone Apps for Skin Cancer Prevention in Young Adults: Randomized Controlled Trial

Consistently across the United States, several European countries, and Australia, young adults are reporting higher levels of sunburn compared with older adults, despite having good knowledge and sun-protective intentions [3-5]. In Australia, people aged 18-24 years were seven times more likely to report sunburn on the previous weekend than those aged >65 years [6]. Young people, men, and those from a lower socioeconomic class or education level are all less likely to engage in preventive activities [7].

Capturing Ultraviolet Radiation Exposure and Physical Activity: Feasibility Study and Comparison Between Self-Reports, Mobile Apps, Dosimeters, and Accelerometers

Capturing Ultraviolet Radiation Exposure and Physical Activity: Feasibility Study and Comparison Between Self-Reports, Mobile Apps, Dosimeters, and Accelerometers

Monitoring physical activity levels is also important in skin cancer prevention studies as three large-scale cross-sectional studies have shown increased levels of physical activity among adults were associated with higher levels of sunburn [2-5]. Ultralight radiation diary app. A) Log-in screen for participants to enter their unique study identifier. B) Home screen. In the home screen, participants select the date to enter their sun exposure and sun protection used for that day.
