Promoting sunscreen use and skin self-examination to improve early detection and prevent skin cancer: quasi-experimental trial of an adolescent psycho-educational intervention

A Study of Skin Cancer Knowledge, Attitudes, and Preventive Practices Among Healthcare Professionals and the General Population in Pakistan: Insights for Healthcare Interventions and Policy Development

Background: Skin cancer is a major global health issue that can be life-threatening. The current study explores the knowledge, attitudes, and practices of healthcare professionals and the general population regarding skin cancer. Method: A cross-sectional study was conducted between January and June 2023 in Lahore, the second-largest city in Pakistan. A total of 407 respondents from the general population and 230 healthcare professionals were recruited using a convenient and snowball sampling technique, respectively. Data were collected using questionnaires and statistical analysis, including chi-square tests, and bivariate logistic regression was performed using SPSS Version 20. Result: In the overall population, 46.4% identified as male, 45.0% as female, and 8.6% chose not to disclose their gender. Significantly differing levels of skin cancer knowledge were observed between genders, with males reporting a higher knowledge (36.4%, crude odds ratio = 1.413, p < 0.001) compared to females (32.9%). In addition, females displayed a more positive attitude (crude odds ratio = 1.874, p < 0.001) and practice (crude odds ratio = 1.401, p < 0.05) toward skin cancer prevention. Furthermore, younger age groups exhibited greater knowledge, attitudes, and practices regarding skin cancer. Education and employment status also have a direct influence on skin cancer knowledge and practices. Moreover, in the current study, healthcare professionals comprised 61.3% physicians, 16.5% nurses, and 22.2% pharmacists. Among these, 37.3% of physicians, 11.3% of nurses, and 12.6% of pharmacists demonstrated the ability to identify common signs and symptoms of skin cancer in a patient (p < 0.001). Furthermore, 44% of physicians regarded regular skin cancer screenings as "very important" (p < 0.01). In addition, 27.4% of physicians and 8.7% of pharmacists exhibited a positive attitude toward regular screening of at-risk patients (p < 0.05). Conclusion: The current study highlights gender and age disparities in skin cancer knowledge and prevention among the general population, emphasizing the need for targeted public health interventions to enhance knowledge and proactive practices. In addition, among healthcare professionals, it reveals variations in knowledge levels, emphasizing the importance of tailored education initiatives to promote consistent skin cancer prevention and management practices within the healthcare community.

When Arguments Meet a Story: An Experiment Testing Message Design Strategies for Skin Cancer Prevention and Detection

Persuasion research often suggests combining different message formats such as facts, statistics, and narratives in message design to maximize persuasive effects. However, the effect of the combination, especially between fact-based arguments and long-form narratives, varies depending on many factors which have been understudied. Our study therefore tested how argument strength, argument position, and target behavior interacted in impacting behavioral outcomes for such a combined message about skin cancer. Findings from our experiment revealed a significant three-way interaction, as weak arguments were more effective when embedding them in a long-form narrative, whereas strong arguments were more impactful when placing them before the narrative. Such an interaction emerged only when messages recommended sunscreen use but not when recommending skin-self exams. We discussed the implications of the findings for message design about skin cancer prevention and detection.

Characterization and Anti-Ultraviolet Radiation Activity of Proanthocyanidin-Rich Extracts from Cinnamomum camphora by Ultrasonic-Assisted Method

The ultrasonic-assisted extraction (UAE) method was employed to separate Cinnamomum camphora proanthocyanidin-rich extracts (PCEs). This extraction process was optimized by the Box-Behnken design, and the optimal conditions, on a laboratory scale, were as follows: an ethanol concentration of 75%, a liquid-to-solid ratio of 24 mL/g, an ultrasonic time of 39 min, and an ultrasonic power of 540 W. Under the obtained conditions, the PCE yield extracted by UAE was higher than that from heat reflux extraction and soaking extraction. An ultra-performance liquid chromatography-tandem mass spectrometry analysis was employed to characterize the phloroglucinolysis products of the C. camphora PCEs, by which epigallocatechin, catechin, epicatechin, and (-)-epigallocatechin-3-O-gallate were identified as the terminal units; epigallocatechin, epicatechin, and (-)-epigallocatechin-3-O-gallate were recognized as extension units. The C. camphora PCEs possessed higher anti-ultraviolet activity in vitro compared with the commercially available sunscreen additive of benzophenone with respect to their ethanol solutions (sun protection factor of 27.01 ± 0.68 versus 1.96 ± 0.07 at a concentration of 0.09 mg/mL) and sunscreens (sun protection factor of 17.36 ± 0.62 versus 14.55 ± 0.47 at a concentration of 20%). These results demonstrate that C. camphora PCEs possess an excellent ultraviolet-protection ability and are promising green sunscreen additives that can replace commercial additives.

Advances in Early Detection of Melanoma and the Future of At-Home Testing

The past decade has seen numerous advancements in approaches to melanoma detection, each with the common goal to stem the growing incidence of melanoma and its mortality rate. These advancements, while well documented to increase early melanoma detection, have also garnered considerable criticism of their efficacy for improving survival rates. In this review, we discuss the current state of such early detection approaches that do not require direct dermatologist intervention. Our findings suggest that a number of at-home and non-specialist methods exist with high accuracy for detecting melanoma, albeit with a few notable concerns worth further investigation. Additionally, research continues to find new approaches using artificial intelligence which have promise for the future.

A Review of the Impact of Sun Safety Interventions in Children

INTRODUCTION

In the United States, melanoma and non-melanoma skin cancers comprise the largest proportion of new cancer diagnoses every year. The prevalence of skin cancer can be largely reduced if proper preventative behaviors are adopted at an early age.

OBJECTIVES

We assessed the impact of various informational, economic, and environmental interventions on sun-protective behaviors, knowledge, attitudes, and sun exposure in the pediatric population reported in previous studies.

METHODS

A systematic search for relevant articles was conducted using three databases. Studies were included if they met the following three criteria: study subjects less than 18 years old, clear, measurable interventions and outcomes, and publication in the English language.

RESULTS

A total of 66 studies were included, of which 48 resulted in positive behavioral changes (i.e. increases in sunscreen application, use of hats and sun-protective clothing, shade-seeking, and avoidance of outdoor activities during peak UV radiation), 28 resulted in increased knowledge, 2 resulted in changes in attitudes towards tanning, and 10 resulted in decreased sun exposure effects (i.e. new sunburns, number of new nevi, and change in pigmentation of the skin).

CONCLUSIONS

It is crucial that children be educated on the importance and benefits of sun protection. Although a variety of interventions showed promise in achieving this goal, the challenges associated with adopting change were evident. This review provides direction for future interventions aimed at improving sun safety in children and illustrates the potential impact that early intervention can have on the incidence of skin cancer in future generations.

Designing a Social Marketing-Based Intervention to Promote Sun-protective Behaviors among Urban Adolescent Boys: A Study Protocol

Background

Skin cancer is one of the most preventable diseases. The purpose of this study is to describe a social marketing-based intervention design protocol to promote sun-protective behaviors among adolescent boys living in urban areas in Yasuj, south west of Iran.

Methods

This study will be conducted based on six specific steps including a qualitative study, a systematic review, development of appropriate tools, a cross-sectional study, intervention designing, and a feasibility study. The main objective of the qualitative study is to elicit the views and opinions of adolescent boys, their parents, and teachers about sun-protective behaviors. In the second step, factors affecting sun-protective behaviors will be reviewed systematically. Based on the findings of the first and second steps, an appropriate model/theory of behavior change will be selected, and a standardized questionnaire will then be developed. In the fourth step, a cross-sectional survey will be conducted using the developed questionnaire to assess current sun-protective behavior practices.

Results

Findings of the first to fourth stages will provide a comprehensive picture of the issue and the affecting factors. During the fifth step, the structure and the content of the intervention package, as well as educational and promotional materials, will be developed and pre-tested. Finally, in the sixth step, a feasibility study will be conducted.

Conclusion

This study will provide practical information on the achieving of content and construct of a community-based social marketing intervention. This protocol reports on how to achieve audience-oriented insights for designing a tailored intervention aimed at promoting sun-protective behaviors among adolescent boys using social marketing.

The Communal Sense on Skin Cancer and Sun Knowledge and Behavior on an Island with Four Seasons of Sun

Purpose: This study aims to determine the relationship between skin cancer and sun knowledge and sun protection behavior of adults living in Dikmen region. Methods: The type of research was cross-sectional. From the population served by the primary health care center (N=1078) located in Dikmen region, the sample of n=284 individuals who applied to the health center while the study was being conducted and volunteered to participate in the study were taken. The data were collected with the 'Socio-Demographic data form', 'Fitzpatrick Skin Type Scale', 'Skin Cancer and Sun Information Scale' and 'Sun Protection Behavior Scale'. Frequency, percentage, mean, Independent t Test, One-way Anova and Pearson Correlation Test were used for data analysis. Results: Participants had the mean age of 49.04±17.65 and 53.2% of them were female. When the skin types of participants were examined according to the Fitzparick classification, it was found that 32.7% of them had average skin color and there were no individuals with very dark/black skin. The 'Skin cancer and sun knowledge scale' of the participants were determined as 12.88±2.51 (min:7.0; max:21.0). The total mean score of the participants in the 'Sun protection behavior scale' was 23.67±6.84 (min:8.0; max:40.0). A positive, weak, statistically valuable relationship was realized between the participants' overall mean score of the 'Skin Cancer and Sun Information Scale' and the total mean score of the 'Sun Protection Behavior Scale' (p

The effectiveness of educational programmes in promoting sun protection among children under the age of 18: a systematic review and meta-analysis

Childhood ultraviolet radiation exposure has a strong connection to the development of skin cancer in later life. Therefore, there have been numerous sun protection educational programmes targeted to this age group. However, the association between these have not been well established. This systematic review aims to summarize the evidence on, and assess, the effectiveness of educational programmes in improving sun protection among children under age-18. The protocol was prospectively registered in the PROSPERO database (CRD42020178264). Per PRISMA guidelines, bibliographic databases CENTRAL, OVID (EMBASE, MEDLINE, PsycINFO), LILACS, trial registries, grey literature and other sources were systematically searched for randomized controlled and clinical controlled trials published between database inception to 9 June 2020. Dual independent review of abstracts and full texts was performed. Eligible studies were assessed for methodological quality using the Cochrane risk-of-bias tool. The primary outcome was postintervention scores [standardized mean difference (SMD)] for sun protection (i) knowledge (ii) attitudes and beliefs (iii) behavioural intentions and behaviours. Sidik-Jonkman random effects meta-analysis, sensitivity and subgroup analyses were performed for specific outcomes (sunscreen and sun-safe hat use) which were sufficiently reported. 1350 publications were identified and 24 eligible trials, conducted across 8 different countries, with sufficient aggregate data were included. Small-to-moderate effects of educational programmes were observed across all sun protection outcomes of interest, but negligible effect sizes were demonstrated when specific outcomes were meta-analysed - sunscreen use, SMD 0.18 (95% CI 0.07-0.29; n = 8) and sun-safe hat use, SMD 0.08 (95% CI, 0.00-0.16; n = 6). A promising approach in the future may be to consider targeting children in secondary education with a digitally delivered interactive intervention. Current evidence, however, is insufficient to assess the effects of potential moderators and change in sun protection outcomes is likely not one-size-fits-all. Further research is warranted to direct intervention design and public policy.

Life Interrupted: Experiences of adolescents, young adults and their family living with malignant melanoma

AIM

Melanoma is one of the most common human malignancies; yet, it is often thought of as a disease of adulthood rather than one affecting adolescents and young adults. This study sought to understand the experiences of adolescents, young adults and their family living with malignant melanoma.

DESIGN

A qualitative study using Interpretive Phenomenological Analysis, through a multi-perspective design.

METHODS

Data collection was conducted between January and August 2018 in each participant's Primary Care Centre when they were attending for an outpatient appointment. Each young person and a nominated family member were interviewed (n = 10) either individually (n = 4) or as a dyad (n = 6) according to their personal choice. In-depth semi-structured interviews were conducted and audio-recorded with the participant's consent. Interview data were transcribed verbatim and analysed.

FINDINGS

The metanarrative 'Life Interrupted' was the core conceptual thread woven throughout the findings. It represents the interconnections and interrelationships between the adolescent or young adult and their family. Being able to recognize the disease and seek support was challenging with often limited physical, emotional or social support resulting in feelings of fear and isolation. Four super-ordinate themes were identified: (a) 'Is it Serious', (b) 'Too Much too Young', (c) 'Not the Same' and (d) 'Time to Live'.

CONCLUSIONS

With the rising incidence of MM in the adolescents and young adults population globally, there are demands to improve healthcare professionals and nurse's knowledge and understanding of MM. As young people with MM experience their journey outside specialist cancer services, the care delivery for this patient group and their families require stronger links between services.

IMPACT

This study will inform the improvement of care delivery for MM in order that this patient group is provided with the same access to service delivery as other adolescents and young adults with cancer.

School-based interventions to improve sun-safe knowledge, attitudes and behaviors in childhood and adolescence: A systematic review

Ultraviolet radiation exposure is the leading cause of skin cancer, and childhood and adolescence is a particularly susceptible life period for exposure. This systematic review assessed whether interventions in elementary and secondary school settings reduced sun exposure, sunburns, and development of melanocytic nevi, and improved sun-safe knowledge, attitudes and sun protection behaviors in childhood and adolescence. A systematic search up to June 2020 of MEDLINE, Embase, CINAHL, Cochrane and ProQuest databases was undertaken, for studies conducted among students in an elementary or secondary school setting that compared an intervention group with a pre-intervention or separate control group. Data were summarized using qualitative synthesis. Pooled effects from meta-analysis with random effects were also reported where appropriate. Sixty-five studies were included (22 randomized, 43 non-randomized). Most studies assessed measures of sun-safe behaviors, knowledge and attitudes (57, 48 and 33 studies, respectively), and observed improved sun protection behaviors and sun-safe knowledge, whereas few studies reduced time in the sun. About half improved participants' attitudes towards tanning desirability. Sunburns and nevus counts were less frequently assessed, but about half of these studies observed a reduction. There was substantial heterogeneity for outcomes except attitudes towards the desirability of tanning (pooled odds ratio from 6 studies: 0.81, 95% confidence interval 0.70-0.94). Key positive intervention features included: elementary school settings, interactive features or multiple components, and incorporating social norm influences. Most studies were classified at high risk of bias. In conclusion, school-based sun-related interventions had positive impacts on behaviors and attitudes among elementary and secondary school children.

Parents' knowledge and understanding of skin cancer and skin self-examination and behaviors to protect their children from the sun

PURPOSE

The aim of this study was to determine parents' knowledge of skin cancer and skin self-examination (SSE) and their efforts to protect their school aged children from the sun.

METHODS

This cross-sectional study was conducted between November 2018 and November 2019 in Turkey with 1004 parents of middle school students.

RESULTS

Of the parents, 53.7% did not have knowledge about skin cancer or SSE, and 76% did not conduct SSEs with their 9-14 years old children. A total of 61.3% of the participants prevented their children from standing in the sun, but 56.1% did not apply sunscreen to their children. The total mean score on the Skin Cancer and Sun Knowledge Scale (SCSKS) was 13.16 ± 3.03. There were significant differences in the total SCSKS scores by parental gender, number of children, education level, economic status, use of sunscreen, frequency of application of sunscreen, use of light-colored clothing, prevention of exposure to sunlight, use of sunglasses outside, knowledge about skin cancer and SSE and knowledge about early diagnosis of skin cancer (p < 0.05).

CONCLUSION

This study showed that parents' behaviors related to sun protection and their skin cancer and SSE knowledge levels were not sufficient. In schools, both students and parents should receive health education regarding skin cancer and prevention methods.

Sunscreen use: a theory-based interventional study using HAPA

Purpose

The current study was aimed to assess health action process approach (HAPA) effectiveness in sunscreen using among paddy workers

Design/methodology/approach

This interventional study was conducted on 177 paddy workers from Rudsar city. The subjects were randomly assigned into motivational, volitional and control groups. The motivational and volitional groups received the educational intervention based on HAPA. Three groups were evaluated in terms of HAPA constructs, intention and behavior at three times before the intervention, immediately afterward and one month later. Chi-square, repeated measure test were used to analyze the data using SPSS software version 19.

Findings

The mean age was 47.78 ± 12.66. The majority of the participants were female (69.3%) and had diploma. based on repeated measure test results the score of the use of sunscreen during the time in intervention groups as well as between the three groups were changed. Based on the results of this study, the score of the constructs of both phases of HAPA in the two groups (motivational and volitional) compared to control group was significantly improved (p < 0.05).

Practical implications

The study shows the use of HAPA for the behavioral change related to sunscreen use among the paddy workers as the high-risk group.

Spatial clusters and temporal trends of malignant melanoma mortality in Ecuador

OBJECTIVE

The aim of this study is two fold. First, it describes the temporal trends of malignant melanoma mortality from 2000 to 2016 in Ecuador. Second, it analyzes the spatial clusters of high mortality rates due to malignant melanoma in the country, from 2011 to 2016.

METHODS

This is an ecological study; we included all death certificates of malignant melanoma from the National Institute of Statistics and Census database in Ecuador from 2000 to 2016. We calculated crude mortality rates and age-standardized mortality rates, all rates are expressed as deaths per 100,000 population. In order to assess the trend of malignant melanoma rates, we obtained average annual percent changes through Joinpoint regression analysis. Spatial scan statistics were used to identify high-risk clusters and the spatial autocorrelation was evaluated through a global Moran index.

RESULTS

In Ecuador, between 2000 and 2016, malignant melanoma caused a total of 958 deaths. Crude mortality rates increased significantly (annual percent change = 4.8%; 95% confidence interval: 2.6-7.0), the age-standardized mortality rate also increased (annual percent change: 2.9%; 95% confidence interval: 0.5-5.4). The most likely cluster included 19 cantons and the second most likely cluster included 10 cantons, located in the Highlands region. The Global Moran I index for the study period shows a positive spatial autocorrelation (0.32; p = 0.001).

CONCLUSION

Mortality due to malignant melanoma in Ecuador significantly increased over the 17-year study period; the spatial analysis and spatial autocorrelation indicates the presence of high-risk occurrence clusters in the Highlands region of the country.

Skin cancer-related knowledge, attitudes, beliefs, and practices among the population in Gulf Cooperation Council countries: a systematic search and literature review

Skin cancers are the most common malignancies diagnosed worldwide. In Gulf Cooperation Council (GCC) countries, skin cancer remains a significant health burden. Multiple studies have attempted to elucidate patient knowledge and attitudes regarding skin cancer risks and behavioral interventions to reduce risks. A systematic literature search of relevant articles was conducted in PubMed, ScienceDirect, and the Saudi Digital Library databases. A narrative analysis of relevant study results was conducted. A total of 12 studies were reviewed across GCC. These studies revealed common themes among GCC populations. Many study participants were aware that excess sun exposure represents a threat to health and increases cancer risk. Several studies reported sun exposure, with a mean of 19.13 h per week. More studies reported patients engaging in lower or no sunscreen use rather than regular sunscreen use. There are discrepancies in the understanding of sun exposure risk and risk mitigation practices among the study populations. Skin cancer poses a significant burden to patients in GCC countries and improved patient education will enhance population health.

Sun protection education for adolescents: a feasibility study of a wait-list controlled trial of an intervention involving a presentation, action planning, and SMS messages and using objective measurement of sun exposure

BACKGROUND

People increase their risk of melanoma unless they are protected from the harmful effects of sun exposure during childhood and adolescence. We aimed to assess the feasibility of a three-component sun protection intervention- presentation, action planning, and SMS messages - and trial parameters.

METHODS

This feasibility wait-list trial was conducted in the United Kingdom in 2018. Students aged 13-15 years were eligible. Feasibility outcomes were collected for recruitment rates; data availability rates for objective measurements of melanin and erythema using a Mexameter and self-reported sunburn occurrences, severity and body location, tanning, sun protection behaviours and Skin Self-Examination (SSE) collected before (baseline) and after the school summer holidays (follow-up); intervention reach, adherence, perceived impact and acceptability. Quantitative data were analysed using descriptive statistics; qualitative data were analysed thematically.

RESULTS

Five out of eight schools expressing an interest in participating with four allocated to act as intervention and one control. Four parents/carers opted their child out of the study. Four hundred and eighty-seven out of 724 students on the school register consented to the study at baseline (67%). Three hundred and eighty-five were in intervention group schools. Objective skin measurements were available for 255 (66%) of the intervention group at baseline and 237 (61%) of the group at follow up. Melanin increased; erythema decreased. Complete self-report data were available for 247 (64%) students in the intervention group. The number of students on the school register who attended the presentation and given the booklet was 379 (98%) and gave their mobile phone number was 155 (40%). No intervention component was perceived as more impactful on sun protection behaviours. Adolescents did not see the relevance of sun protection in the UK or for their age group.

CONCLUSIONS

This is the first study to use a Mexameter to measure skin colour in adolescents. Erythema (visible redness) lasts no more than three days and its measurement before and after a six week summer holiday may not yield relevant or meaningful data. A major challenge is that adolescents do not see the relevance of sun protection and SSE.

Development and piloting of 'When Cancer Comes Along': A cancer awareness program for Australian secondary school students

ISSUE ADDRESSED

Given the increasing prevalence of cancer, there is a growing need for health interventions educating individuals about the disease and its impacts, risk-reduction strategies and how to support others who are affected. School-based programs are a promising medium addressing these issues in adolescents, yet no comprehensive cancer education program exists in Australia. This paper reports on the piloting of a cancer awareness program for Australian students.

METHODS

When Cancer Comes Along is a 90-minute interactive presentation covering cancer's impacts, risk-reduction strategies and how to support those affected. The program was piloted in four Australian secondary schools, with students (N = 113, 13-16 years) and teachers (N = 2) providing feedback via postprogram survey.

RESULTS

Participants reported high satisfaction overall (92%-97%) and with each program component (71%-95%), and agreed that the program achieved learning outcomes (72%-95%).

CONCLUSIONS

Results indicate that When Cancer Comes Along is relevant, engaging and age-appropriate. Participants reported improved understanding of cancer, its impacts, risk-reduction strategies and how to support those affected. A larger-scale evaluation is underway to more comprehensively evaluate program outcomes. SO WHAT?: The program has potential in educating students about various aspects of the cancer experience. It further demonstrates the feasibility and value of addressing psychosocial impacts and support strategies as well as information about cancer risks, elements which have not previously been combined in educational interventions. Equipping adolescents with the knowledge and skills to reduce their cancer risk and support others who are affected has significant health promotion implications for cancer prevention and support provision.
