Rural-urban differences in meeting of physical activity recommendations by sun exposure and protection behaviors in the United States.

OBJECTIVE: To examine associations between sun protection behaviors and physical activity (PA) by rural and urban residence in the United States. METHODS: We analyzed data from the National Health and Nutrition Examination Survey (2013-2018), restricting to participants ages 20-59 with sun behavior data. Sunburns, sun exposure, and sun protection measures were dichotomized (yes/no): ≥1 sunburn in the past year, 2+ hour outside during workdays or non-workdays, and never/rarely/sometimes using sunscreen, wearing long sleeves, and staying in the shade. Meeting PA recommendations (yes/no) was defined as ≥150 min of vigorous/moderate or ≥ 75 min vigorous PA per week. Associations between sun behaviors and PA were analyzed using logistic regression models, which accounted for survey-weights and potential confounders, and stratified by rural-urban status. RESULTS: Rural and urban individuals meeting PA recommendations had greater odds of spending 2+ hour outside during workdays (OR: 2.26 [1.88, 2.74] and 3.95 [2.72, 5.73]) and non-workdays (OR: 2.06 [1.78, 2.38] and 3.33 [2.47, 4.46]). Among urban residents, odds of staying in the shade were lower among those who met PA recommendations (OR: 0.78 [0.66, 0.92]). We did not observe differences in sunburns or other sun behaviors by PA status, regardless of rurality. CONCLUSIONS: Meeting PA recommendations was associated with greater sun exposure in both rural and urban populations. Additional exercise location (indoors/outside) data is needed to inform PA and skin cancer prevention interventions to reduce unintended increases in sun exposure and reductions in PA, respectively, especially among rural populations.

Association between sun-protective behaviors and hypertension: a cross-sectional study from National Health and Nutrition Examination Survey 2009 to 2014.

BACKGROUND: In previous studies, sun-protective behaviors increased cardiovascular incidence. Our present article is to further analyze the potential relationship between sun-protective behaviors (staying in the shade, wearing long-sleeved clothing, and applying sunscreen) and hypertension. METHOD: The present cross-sectional study evaluated 8,613 participants (aged 20-60 years) from the National Health and Nutrition Examination Survey (NHANES) obtained between 2009 and 2014. We performed multiple logistic regression analysis to examine the relationship between sun-protective behaviors and hypertension. Subgroup analysis was then performed. Multiple linear regression analysis was utilized to examine the relationship of sun-protective behaviors and each sun-protective behavior with systolic and diastolic blood pressure, stratified by sex and race. RESULTS: A total of 8,613 participants (weighted n = 127,909,475) were applied in our study, including 1,694 hypertensive subjects. Our study demonstrated that sun-protective behaviors of the 2-3 category were associated with increased risk of hypertension, but not with higher systolic and diastolic blood pressure. In subgroup analysis, men, Mexican American, and 25 < BMI ≤ 30 who reported sun-protective behaviors (2-3) were prone to hypertension. Multiple linear regression models showed that non-Hispanic white men with sun-protective behaviors (2-3) were positively associated with systolic and diastolic blood pressure. The association between other-Hispanic men with frequent wearing long-sleeved clothing and diastolic blood pressure was positively correlated. CONCLUSION: Sun-protective behaviors of the 2-3 category could increase the incidence of hypertension, but not increase systolic and diastolic blood pressure. We only found that non-Hispanic white men who reported sun-protective behaviors (2-3) were positively associated with systolic and diastolic blood pressure. These findings suggested that excessive sun-protective behaviors should be avoided.

Risk factors and early prevention of skin cancer in rural older outdoor workers: A scoping review.

Skin cancer risk increases with age and prolonged exposure to ultraviolet radiation (UVR), particularly in rural geographical locations and for individuals with light skin complexions. However, the impact of UVR-induced skin cancer risk and sun-protective behaviors in rural older populations working outdoors has yet to be explored. A scoping review was conducted to fill this gap, with 12 articles meeting the inclusion criteria of aged 50 years and older among rural outdoor workers. Skin cancer risk factors, prevention strategies, and barriers to sun-protective behaviors were summarized for each study. The scoping review addressed some key differences in age-related effects of UVR among rural older outdoor workers compared to studies among adults in general. Findings have policy and research implications that highlight the need to design feasible preventive strategies to reduce rural disparities in cancer care and enhance access to preventive services for this high-risk population.

Incidence and public health burden of sunburn among beachgoers in the United States.

The beach environment creates many barriers to effective sun protection, putting beachgoers at risk for sunburn, a well-established risk factor for skin cancer. Our objective was to estimate incidence of sunburn among beachgoers and evaluate the relationship between sunburn incidence and sun-protective behaviors. A secondary analysis, of prospective cohorts at 12 locations within the U.S. from 2003 to 2009 (n = 75,614), were pooled to evaluate sunburn incidence 10-12 days after the beach visit. Behavioral and environmental conditions were cross-tabulated with sunburn incidence. Multivariable logistic regression was used to estimate the association between new sunburn and sun-protective behaviors. Overall, 13.1% of beachgoers reported sunburn. Those aged 13-18 years (16.5%), whites (16.0%), and those at beach locations along the Eastern Seaboard (16.1%), had the highest incidence of sunburn. For those spending ≥5 h in the sun, the use of multiple types of sun protection reduced odds of sunburn by 55% relative to those who used no sun protection (Odds Ratio = 0.45 (95% Confidence Interval:0.27-0.77)) after adjusting for skin type, age, and race. Acute health effects of sunburn tend to be mild and self-limiting, but potential long-term health consequences are more serious and costly. Efforts to encourage and support proper sun-protective behaviors, and increase access to shade, protective clothing, and sunscreen, can help prevent sunburn and reduce skin cancer risk among beachgoers.

Sun-protective behaviors in patients with cutaneous hyperpigmentation: A cross-sectional study.

BACKGROUND: Disorders of hyperpigmentation are seen commonly in clinical practice. Despite numerous studies investigating sun-protective habits among healthy persons, little is known about these behaviors within patient populations with hyperpigmentation disorders. OBJECTIVE: We sought to examine photo-protective behaviors and their associations in individuals with disorders of hyperpigmentation. METHODS: This cross-sectional study was conducted with 404 adults who complained of cutaneous hyperpigmentation. RESULTS: About 67.5% reported using a product containing sunscreen, and 91% endorsed using one with a sun protection factor of 21 or higher. Among the participants, 48.5% were not sure if their sunscreen provided broad-spectrum protection, and only 7.6% reapplied every 2 hours. The odds of a patient with melasma using sunscreen were 6.7 times the odds of a patient with postinflammatory hyperpigmentation using sunscreen (P < .001). Additional predictors for sunscreen use were female sex (OR = 3.8, P = .0004) and disease duration of ≥1 year (OR = 2.1, P = .003). In a multivariate analysis, the odds ratio of sunscreen use among African Americans compared to whites was 0.31 (P = .008). LIMITATIONS: Limitations included recall bias, question misinterpretation, and reporter bias. CONCLUSION: Patients diagnosed with postinflammatory hyperpigmentation, men, and those with disease duration <1 year reported lower sunscreen usage. These groups might benefit from increased counseling on sun-protective behaviors.

Sun protective behaviors among adolescents and young adults in the United States.

PURPOSE: We described sun protective behaviors in adolescents and young adults (AYA) compared to older adults. METHODS: We used data from the 2013-2018 National Health and Nutrition Examination Survey, a nationally representative samples of the civilian, noninstitutionalized US population (10,710 respondents aged between 20 and 59 and without a history of skin cancer diagnoses). The primary exposure for the study was age group: aged 20-39 defined as AYA and aged 40-59 as adults. The outcome variable was sun protective behaviors: stay in the shade, wear a long-sleeved shirt, use sunscreen, at least one of the three; and all three measures. Multivariable logistic regression models were used to assess association between age group and sun protective behaviors adjusting for sociodemographic factors. RESULTS: Overall, 51.3% of respondents were AYA, 76.1% reported staying in the shade, 50.9% using sunscreen, 33.3% wearing long-sleeved clothes, 88.1% engaging in one of the three behaviors, and 17.1% engaging in all three behaviors. In the adjusted models, the odds of engaging in all three behaviors among AYAs was 28% (aOR: 0.72, 95% CI: 0.62-0.83) lower than adult respondents. Compared to adults, AYAs were 22% less likely to wear long sleeved clothes (aOR: 0.78, 95% CI: 0.70-0.87). There were no significant differences in the odds of engaging in at least one sun protective behavior, using sunscreen, and staying in the shade between AYAs and adults. CONCLUSIONS: More targeted interventions need to be implemented to decrease the risk of skin cancer in the AYA population.

Prevalence of self-skin exams and full body skin exams among patients with disabilities.

Full body skin exams and self-skin exams are screening methods associated with reduced skin cancer incidence due to earlier detection and treatment of lesions. We performed a retrospective analysis on skin cancer screening and risk factors from the Health Information National Trends Survey (HINTS). The study cohort comprised a weighted population of 478,008,736 respondents, of whom 26,727,370 were patients with disabilities. Respondents with disabilities reported a lower frequency of full body skin exams (OR 0.74; CI 95% 0.69-0.79; P < 0.001) and self-skin exams (OR 0.85; CI 95% 0.78-0.91; P < 0.001), compared to respondents without disabilities. Lower rates of self-guided and clinician-guided screening may adversely affect skin cancer-related morbidity and mortality in persons with disabilities. Future research is needed to identify barriers to self-skin exams and full body skin exams in this population.

Sunburn Frequency and Sun Protection Attitudes among Ocean Lifeguards at Florida Beaches.

Objective: Research exists examining sunburn risks, sun protective behaviors, and interventions among pool lifeguards; however, ocean lifeguard research is limited. This study aimed to determine sunburn prevalence and associations between sunburn with photoprotective attitudes and habits among Florida ocean lifeguards. Methods: A cross-sectional study was electronically administered in 2021 to ocean lifeguards using sun protection questions. Recruitment occurred through three lifeguard agencies. The frequency of self-reported sunburns from the prior season and the opinions and practices related to photoprotection and tanning were obtained. Results: Complete data were obtained from 77 (37%) of 207 lifeguards who served during the 2020 swimming season (mean [SD] age, 22.9 [8.31] years; 40 male (52.0%) and 37 female (48.0%)). Sunburn was common with only four (5.2%) lifeguards reporting no sunburn. In total, 26 (33.8%) reported five or more sunburns. The median sunburn frequency was three. Reporting three or more sunburns was positively associated with being a teenager (16 to 18 years) (aOR: 14.9, 95% CI 3.5 to 64.2) or young adult (19 to 23 years) (aOR: 6.4, 95% CI 1.6 to 25.2) and having a neutral opinion regarding sunscreen effectiveness (aOR: 4.5, 95% CI 1.1 to 18.7) in logistic regression models. Limitations: Self-reported sunburns were recalled and not clinically evaluated. Recall, participation, and social desirability biases may have been present. Conclusion: Ocean lifeguards reported appreciably high rates of sunburn, especially younger lifeguards. Increased photoprotection education, engineering controls, and research are warranted for this occupational group.

Sun-protection Behaviors Among Active Members of the United States Lifesaving Association.

BACKGROUND: Ultraviolet radiation exposure is the most prominent modifible risk factor for developing both melanoma and non-melanoma skin cancers. OBJECTIVE: We sought to elucidate sun-protective behaviors among active members of the United States Lifesaving Association (USLA), a nationwide nonprofit organization comprising beach lifeguards, and to identify positive and negative predictors of sun protective behaviors. METHODS: This was a pilot, cross-sectional survey study. All USLA lifeguards aged 18 years or older were invited to complete a 19-item survey. Data were collected anonymously at the 2018 USLA National Lifeguard Championships in Virginia Beach, Virginia. Participant characteristics and sun-protective behaviors (e.g., hat, sunglasses, protective clothing, sunscreen, and seeking shade) were surveyed. A composite score (0-10 points) was created based on sun-protective behaviors. Simple linear regression models were fit to assess the relationship between lifeguard characteristics and the sun-behavior composite score and a multiple linear regression model was used to assess their overall positive or negative effect on composite scores. RESULTS: A total of 215 USLA lifeguards completed the survey study; of these, 64.2% were male and the average age was 34.2 years. The most common sun-protective behavior was wearing sunglasses (85%), followed by applying sunscreen (65%), wearing a hat (46.7%), seeking shade (38.6%), and wearing protective clothing (34.0%). The overall average composite score was 7.5±1.9 points. In the multiple linear regression model, female sex (ß=-0.85; p=0.0012), desiring a tan (ß=-1.26; p=0.0008), and working more summer daytime hours (ß=-0.49; p=0.049) negatively impacted composite scores. CONCLUSIONS: USLA beach lifeguards are subject to sun-exposure patterns and practiced sun-protective behaviors that potentially place them at higher risk for skin cancer.

Does one's geographic location influence their use of sun protection? A survey of 3,185 U.S. Residents.

To determine if geographical differences exist in practice of sun protective behaviors across the United States, we performed a retrospective, cross-sectional analysis of data from the Health Information National Trends Survey 4 Cycle 3. Self-reported sun protective behaviors and demographic information were collected for individuals from nine regions across the United States in 2013. Regions followed United States census divisions, including New England, Middle Atlantic, East North Central, West North Central, South Atlantic, East South Central, West South Central, Mountain, and Pacific. Study participants included 3,185 people from nine census regions. Sun protection was uncommonly practiced in the United States. The use of sunscreen in the West North Central region was the lowest sun protective practice. Long pants were more commonly worn in the West South Central and the Pacific. Sun protective behavior rates are low for all geographic locations across the United States. Future public health campaigns should place less emphasis on geographical influences of sun protective behaviors and focus more so on comprehensive, nationwide sun prevention campaigns.

A Brief Dermatology Curriculum in Skin Cancer Detection and Prevention to Improve Medical Student Knowledge and Confidence.

Introduction: While the incidence of skin cancers continues to rise, there remains a disproportionate lack of introductory training on skin cancer screening and identification of modifiable behaviors in medical curricula. Trainees and students have cited low confidence in their ability to counsel patients and lack of instruction as barriers. Methods: To address this need, we created a 1-hour didactic lecture based on a cognitive teaching framework for third-year medical students during their core primary care clerkship. The session highlighted visual identification of different skin cancers, factors increasing individual risk, and photoprotective behaviors. Session content was based on American Academy of Dermatology recommendations for skin cancer prevention. An assessment of knowledge, behaviors, and attitudes given before, immediately following, and at 6 months after the session was used to determine efficacy. Results: One hundred eight students before and immediately after the session demonstrated significantly improved knowledge (mean correct: 71% presession vs. 99% postintervention, p < .0001). Based on 39 participants completing 6-month follow-up, knowledge remained improved (mean answered correctly: 80%, p < .0001). Confidence in patient counseling on preventive behaviors, risk assessment, and reported likelihood of counseling significantly increased across the three time points (p < .0001 for all attitude questions). Specific topics included appropriate referral to a dermatologist, sunscreen application, and dangers of indoor tanning bed usage. Discussion: Our session on skin cancer screening and prevention demonstrated improvements in medical student knowledge, confidence, and patient counseling likelihood. This introductory curriculum could be adapted for multiple core clerkships or specialties.

Walking and Sun Protective Behaviors: Cross-Sectional Associations of Beneficial Health Factors.

Sun protective behaviors and physical activity have the potential to reduce cancer risk. Walking is the most common type of physical activity in the United States, but it is unclear whether sun protective behaviors differ by categories of walking, such as leisure versus transportation walking. We examined whether sun protective behaviors varied by category or duration of walking in the 2015 National Health Interview Survey (N = 26,632), age ≥ 18 years. We used logistic regression to estimate sunscreen use, sun avoidance, and sun protective clothing use by four categories of walking (no reported walking, transportation only, leisure only, or walking for both) and separately for walking duration for the general population and sun-sensitive individuals. Prevalence of sunscreen use varied across walking categories and the odds of use were higher with longer walking duration for transportation and leisure compared to those who reported no walking. Sun avoidance varied across walking categories and the odds of avoidance were lower with longer duration leisure but not transportation walking. Sun protective clothing varied across walking categories and the odds of use were higher for longer duration transportation, but not leisure walking. Data on the concurrence of walking and sun protection is needed to further understand the relationship between these health behaviors. By examining leisure and transportation walking, we found variations in sun protective behaviors that may provide important insight into strategies to increase sun protection while promoting physical activity.
