Randomized controlled trial of a sun protection intervention for children of melanoma survivors

Persistent poverty and incidence-based melanoma mortality in Texas

PURPOSE

Previous studies have shown that individuals living in areas with persistent poverty (PP) experience worse cancer outcomes compared to those living in areas with transient or no persistent poverty (nPP). The association between PP and melanoma outcomes remains unexplored. We hypothesized that melanoma patients living in PP counties (defined as counties with ≥ 20% of residents living at or below the federal poverty level for the past two decennial censuses) would exhibit higher rates of incidence-based melanoma mortality (IMM).

METHODS

We used Texas Cancer Registry data to identify the patients diagnosed with invasive melanoma or melanoma in situ (stages 0 through 4) between 2000 and 2018 (n = 82,458). Each patient's PP status was determined by their county of residence at the time of diagnosis.

RESULTS

After adjusting for demographic variables, logistic regression analyses revealed that melanoma patients in PP counties had statistically significant higher IMM compared to those in nPP counties (17.4% versus 11.3%) with an adjusted odds ratio of 1.35 (95% CI 1.25-1.47).

CONCLUSION

These findings highlight the relationship between persistent poverty and incidence-based melanoma mortality rates, revealing that melanoma patients residing in counties with persistent poverty have higher melanoma-specific mortality compared to those residing in counties with transient or no poverty. This study further emphasizes the importance of considering area-specific socioeconomic characteristics when implementing place-based interventions to facilitate early melanoma diagnosis and improve melanoma treatment outcomes.

Moderating influences on parents' fatalistic beliefs about cancer and their association with sun safety behaviors among children of melanoma survivors: Implications for treatment

The purpose of this study is to examine the association between parents' fatalism about melanoma and their children's sun protection, and the potential moderating role of parent-child communication. In this observational study of N = 69 melanoma-surviving parents of children ages 8-17, parents reported on their own melanoma fatalism, as well as their children's sun safety behaviors and parent-child discussion about sun safety. Parent gender, family history of melanoma, and frequency of parent-child discussions moderated the relationship between parents' fatalism and children's sun safety behaviors. Among mothers and parents with a family history of melanoma, high fatalism was associated with lower child sunscreen use, especially when discussions were less frequent. Melanoma surviving parents' fatalistic beliefs about cancer indirectly influence their children's health behavior and are a risk factor for unsafe sun behavior. Attending to parent gender, family history, and their communications about protective behaviors as co-factors of this risk could inform future intervention targeting.

The Family Lifestyles, Actions and Risk Education (FLARE) study: Protocol for a randomized controlled trial of a sun protection intervention for children of melanoma survivors

BACKGROUND

Children of parents who had melanoma are more likely to develop skin cancer themselves owing to shared familial risks. The prevention of sunburns and promotion of sun-protective behaviors are essential to control cancer among these children. The Family Lifestyles, Actions and Risk Education (FLARE) intervention will be delivered as part of a randomized controlled trial to support parent-child collaboration to improve sun safety outcomes among children of melanoma survivors.

METHODS

FLARE is a two-arm randomized controlled trial design that will recruit dyads comprised of a parent who is a melanoma survivor and their child (aged 8-17 years). Dyads will be randomized to receive FLARE or standard skin cancer prevention education, which both entail 3 telehealth sessions with an interventionist. FLARE is guided by Social-Cognitive and Protection Motivation theories to target child sun protection behaviors through parent and child perceived risk for melanoma, problem-solving skills, and development of a family skin protection action plan to promote positive modeling of sun protection behaviors. At multiple assessments through one-year post-baseline, parents and children complete surveys to assess frequency of reported child sunburns, child sun protection behaviors and melanin-induced surface skin color change, and potential mediators of intervention effects (e.g., parent-child modeling).

CONCLUSION

The FLARE trial addresses the need for melanoma preventive interventions for children with familial risk for the disease. If efficacious, FLARE could help to mitigate familial risk for melanoma among these children by teaching practices which, if enacted, decrease sunburn occurrence and improve children's use of well-established sun protection strategies.

Attitudes, Behaviors, and Risks of Sun Protection to Prevent Skin Cancer Amongst Children, Adolescents, and Adults

Skin cancer is the most common cancer diagnosis worldwide. Many factors are involved in the development of skin cancers, but ultraviolet (UV) light exposure is the most modifiable. Our lifetime cumulative UV exposure may be a result of poor sun protection practices in childhood and adolescence. Modifying the attitudes and behaviors of children can be done in the classroom, at recreational activities, and at home. A review of the literature was conducted using Embase and PubMed to examine the relationship between attitudes and behaviors as they relate to sun protection strategies. Well-developed, standardized sun protection educational programs are needed to instruct children and adolescents. Individualized counseling from physicians or online programs is needed to help parents increase sun-safe standards for their children. Many young women utilize indoor tanning beds frequently, but many instructional programs increased their tanning bed usage. Time should be allotted at schools, sports practices, camps, and other outdoor activities for sunscreen reapplication. Many parents and children report the media is their primary source of information about sun safety. Media outlets may positively change attitudes and behaviors when reporting about sun safety. Parents and children need individualized programs or counseling to reduce ultraviolet (UV) exposure and increase sun protection. At-risk populations need tailored instruction, but few strategies have worked to decrease UV exposure.

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.

Moderators of the Effects of mySmartSkin, a Web-Based Intervention to Promote Skin Self-examination and Sun Protection Among Individuals Diagnosed With Melanoma

BACKGROUND

Identifying the characteristics of persons who benefit more from behavioral interventions can help health care providers decide which individuals should be offered particular interventions because this is the subgroup of persons who are more likely to derive greater benefit from the intervention and refine the underlying constructs of the model guiding the intervention.

PURPOSE

This study evaluated possible demographic, medical, knowledge and attitudinal, and psychosocial variables that may moderate the impact of an online intervention, called mySmartSkin (MSS), on engagement in skin self-examination (SSE) and sun protection behaviors among melanoma survivors.

METHODS

Participants completed a baseline survey and were then randomized to the MSS condition or usual care. Follow-up surveys were completed by participants at 8-, 24-, and 48-week postrandomization.

RESULTS

A greater impact of MSS on SSE was illustrated among participants with more phenotypic skin cancer risk factors and participants reporting lower baseline self-efficacy in conducting SSE. A more favorable response of MSS on sun protection behaviors was shown when initial knowledge about abnormal lesions and sun protection barriers were high. Greater use of MSS and more favorable evaluations of it were also associated with higher intervention response.

CONCLUSIONS

Future studies seeking to improve SSE and sun protection among melanoma survivors might benefit from focusing on survivors who report more skin cancer risk factors, lower self-efficacy in conducting SSE, less knowledge about what abnormal skin lesions look like, more perceived barriers to sun protection behaviors, and less worry about recurrence and cancer-related distress.

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.

The effect of 'I am Protecting my Child from the Sun' programme on parental sun protection behaviours: Randomized controlled trial

AIMS

This study aims to examine the effect of the 'I am Protecting my Child from the Sun' program based on the social cognitive theory, on parental use of sun protection products and sun avoidance behaviours.

DESIGN

Cluster randomized controlled trial.

METHODS

The study was conducted with three groups using a pre-test, post-test, and follow-up design. The study included 185 parents, of which 63 were in the education group, 62 were in the education + SMS group, and 60 were in the control group. The parents in the intervention group were engaged in the 'I am Protecting my Child from the Sun' program for a period of 6 weeks, while the education + SMS group, in addition to the program, also received. Primary outcomes include sunscreen use and sun avoidance behaviour and secondary outcomes were self-protection and protection of their children's behaviour. A repeated-measures ANOVA and marginal homogeneity were the main statistical tests.

RESULTS

The interventions made as part of the 'I am Protecting my Child from the Sun' program increased the following behavioural components of parents in the education group and the education + SMS group, compared with the control group: sun protection product use behaviours, sun avoidance behaviours, and behaviours related to protecting themselves and their children from the sun. There was an even higher increase in these behavioural components for those parents who also received short reminder text messages.

CONCLUSION

The 'I am Protecting my Child from the Sun' program and the receiving of short reminder messages had positive effects on the parents' behaviours related to protecting themselves and their children from the sun.

IMPACT

The 'I am Protecting my Child from the Sun' developed parents' sunscreen use self-efficacy, norms/attitudes about sunscreen use and sunscreen use expectancy behaviour, and reduced their impediments to sunscreen use behaviour. In addition, the program developed parents' sun avoidance self-efficacy, norms/attitudes about sun avoidance and sun avoidance expectancy behaviours, and reduced tanning expectancy behaviour. Receiving SMS messages following the training was effective in parental behaviours for use of sunscreen, sun avoidance, and protecting themselves and their children from the sun. Registration number: Study is registered at ClinicalTrials.gov NCT04251598.

A pilot study of a telehealth family-focused melanoma preventive intervention for children with a family history of melanoma

OBJECTIVE

Melanoma preventive interventions for children with familial risk are critically needed because ultraviolet radiation (UVR) exposure and sunburn occurrence early in life are the primary modifiable risk factors for melanoma. The current study examined the feasibility and acceptability of a new, family-focused telehealth intervention for children with familial risk for melanoma and their parents. The study also explored changes in child sun protection and risk behaviors, sunburn occurrence, and objectively measured UVR exposure.

METHODS

This was a prospective study with a single-group design (n = 21 parent-child dyads, children ages 8-17). Dyads were asked to participate in three in-person assessments and three live video teleconference intervention sessions.

RESULTS

The intervention was feasibly delivered, and the intervention content was acceptable to parents and children. The intervention was associated with improvements in child use of certain sun protection strategies over time and declines in child UVR exposure.

CONCLUSIONS

A telehealth-delivered,family-focused melanoma preventive intervention was feasibly delivered and was acceptable to parent-child dyads. Future melanoma preventive interventions for this at-risk population could incorporate eHealth technologies to facilitate improvements in use of sun protection and monitoring of UVR exposure. This trial was registered with Clinicaltrials.gov, number NCT02846714.

Differences in Sun Protection Behaviors Between Rural and Urban Communities in Texas

PURPOSE

The increasing incidence of skin cancer is a global health issue. In order to identify at-risk populations in Texas, we compared sun protection behaviors and sunburn history across rural and urban counties.

METHODS

An online health screening survey collected data from a nonprobability sample of Texas residents in 2018. Data were weighted by sex, age, race, and ethnicity. Multinomial multivariable logistic regression identified key factors associated with sun protection behaviors and sunscreen use. Weighted Pearson's χ²  test identified differences between urban and rural respondents in strength of sunscreen used and sunburn history.

FINDINGS

Rural residents in Texas were less likely to seek shade (OR = 0.58; P = .004) and less likely to use sunscreen lotion (OR = 0.65; P = .013) compared to their urban counterparts. Sunscreen use was also lower among current versus never smokers (OR = 0.67; P = .034) but higher in those with personal versus no cancer history (OR = 2.14; P = .004). Although rural versus urban residents were more likely to use higher SPF sunscreen (P < .002), they had more blistering sunburns over the course of their life (P < .001) and these injuries were more likely to occur at an earlier age, between 5 and 14 years old (P < .001).

CONCLUSIONS

Increased attention to sun protective behaviors among rural communities in Texas is vital to help reduce the high prevalence of sunburn injury and incidence of skin cancer.

Randomized trial of a web-based survivor intervention on melanoma prevention behaviors of first-degree relatives

OBJECTIVES

Melanoma can be prevented through reducing sun exposure and detected early by increasing examination of skin for lesions. First-degree relatives of melanoma cases have higher risk than the general population and, therefore, could be targets of behavioral interventions through families. We tested the effects of a family-based web delivered intervention to melanoma families on the melanoma risk reduction behaviors of first-degree relatives of melanoma cases.

METHODS

A total of 313 families that included one first-degree relative were recruited to join this randomized trial. All intervention families received access to the Suntalk website developed to promote family communication and behavioral risk reduction among families of melanoma survivors.

RESULTS

First degree relatives in the intervention arm significantly increased their yearly performance of both skin self examination and thorough provider examination from baseline to 12-month follow-up while the control FDRs decreased their yearly performance of both of those behaviors (p's = 0.006 and 0.005, respectively). Several sun protection behaviors increased significantly in FDRs in the intervention arm but not the control arm, including wearing a covering on the head (p = 0.005), staying in available shade (p = 0.008), and avoiding sun exposure during peak hours (p = 0.010). Some of these changes were mediated by perceptions of risk and other process variables.

CONCLUSIONS

A web-based intervention can reduce risk of melanoma through changes in relevant behaviors among first-degree relatives of melanoma survivors. Future research should identify methods for making this type of intervention accessible to more families and for broadening the reach to other types of cancer families.

PRACTICE IMPLICATIONS

This program can be provided to melanoma families to improve their sun protection and screening behaviors, at the point of diagnosis.

Development of an Educational Program Integrating Concepts of Genetic Risk and Preventive Strategies for Children with a Family History of Melanoma

Efforts to prevent melanoma, especially for those at elevated risk for the disease, should ideally begin during childhood. However, there are few preventive interventions targeting children who are at higher risk for melanoma due to a family history of the disease. Further, there are no educational interventions that aim to help these at-risk children understand their risk for melanoma and the ways in which preventive behaviors, such as sun protection, can mitigate their risk. The current paper describes a multidisciplinary team's process for creating a developmentally appropriate educational intervention about melanoma risk and prevention for children ages 8-17 years who have a family history of melanoma. Drawing from the fields of dermatology, health behavior change and education, genetic risk communication, science education, and graphic arts, the multimedia intervention created covers key learning points relevant to understanding melanoma, the role of DNA damage in melanoma development, inherited risk factors for melanoma, environmental factors causing DNA damage, and methods for preventing DNA damage, such as sun protective behaviors. Lessons learned during the development of the educational intervention, particularly relevant to multidisciplinary team interactions, are discussed. Implications for future testing and refinement of the novel educational content are also reviewed.

Skin cancer interventions across the cancer control continuum: A review of experimental evidence (1/1/2000-6/30/2015) and future research directions

While the general efficacy of skin cancer interventions have been reviewed, employing the cancer control continuum would be useful to identify research gaps at specific cancer control points. We characterized the intervention evidence base for specific behavioral targets (e.g., tanning, sun protection, screening) and clinically related targets (e.g., sunburn, skin exams, cancers) at each point in the cancer control continuum. The review included articles published from 1/1/2000-6/30/15 that had an experimental design and targeted behavioral intervention in skin cancer (e.g., specific behaviors or clinically related targets). The search yielded 86 articles, including seven dissemination studies. Of the 79 non-dissemination studies, 57 exclusively targeted primary prevention behaviors, five exclusively targeted screening, 10 targeted both detection and prevention, and eight addressed cancer survivorship. Among prevention studies (n=67), 29 (43%) targeted children and 38 (57%) targeted adults. Of the 15 screening studies, nine targeted high-risk groups (e.g., men aged ≥50 years) and six targeted the general population. Although research has focused on skin cancer prevention, empirically validated interventions are still needed for youth engaged in indoor tanning and for behavioral interventions to pursue change in clinically relevant targets. Research must also address detection among those at highest risk for skin cancer, amelioration of emotional distress attendant to diagnosis and treatment, and survivorship concerns. We discuss essential qualities and opportunities for intervention development and translational research to inform the field.

Improving Sun-Protective Behaviors and Self-Skin Examinations Among African Americans: A Randomized Controlled Trial

BACKGROUND

Few studies describing sun-protective behaviors, knowledge, and self-efficacy in African Americans exist. Although educational programs targeting Caucasians and Hispanics have been successful in increasing melanoma awareness and knowledge, no such investigation has been applied to African Americans.

OBJECTIVE

To evaluate the effectiveness of a brochure or video educational intervention on the sun-protective behaviors, knowledge, and self-efficacy regarding melanoma in African Americans.

MATERIALS AND METHODS

A randomized controlled trial of a presurvey and postsurvey, in an academic outpatient dermatology clinic. Participants were self-identified African Americans, at least 18 years old, fluent, and literate in English. Patients randomized to the brochure-intervention group (n = 72) received a melanoma brochure from the National Cancer Institute. Patients randomized to the video-intervention group (n = 71) received the brochure and watched an online melanoma tutorial.

RESULTS

Sun-protective behaviors, knowledge, and self-efficacy regarding melanoma all improved equally from pre-to posteducation, in both the brochure- and video-intervention groups.

CONCLUSION

Melanoma educational interventions similar to those previously demonstrated to be successful in Caucasian and Hispanic populations are also effective among African Americans.

A novel educational intervention targeting melanoma risk and prevention knowledge among children with a familial risk for melanoma

OBJECTIVE

To examine the acceptability of and preliminary effects associated with a novel educational intervention for children at elevated risk for melanoma. The intervention incorporated information on mechanisms through which melanoma preventive behaviors mitigate risk for melanoma and was delivered to parents and children concurrently.

METHODS

Twenty-two parents (with a personal history of melanoma or spouse with a history of melanoma) and 33 children (mean age 11.8 years) were asked to complete questionnaires immediately prior to and after an educational session and at a one-month follow-up.

RESULTS

Both parents and children endorsed that the educational materials were acceptable. Knowledge about melanoma risk and preventive and screening behaviors increased significantly. Children's perceived risk for melanoma increased significantly, while parents' perceptions of children's risk started at a higher level and remained constant. There were significant increases in reported engagement in sun protective behaviors.

CONCLUSION

The educational intervention shows promise in terms of its acceptability and effects on participant knowledge, perceived risk, and engagement in melanoma preventive behaviors.

PRACTICE IMPLICATION

Children at elevated risk for melanoma and their parents may benefit from receiving educational information on their disease risk and strategies for prevention and screening.

Pediatric Predispositional Genetic Risk Communication: Potential Utility for Prevention and Control of Melanoma Risk as an Exemplar

Predispositional genetic testing among minor children is intensely debated due to the potential benefits and harms of providing this type of genetic information to children and their families. Existing guidelines on pediatric genetic testing state that predispositional testing could be appropriate for minors if preventive services exist that mitigate children's risk for or severity of the health condition in question. We use the example of hereditary melanoma to illustrate the rationale for and potential application of genetic risk communication for an adult-onset cancer to a pediatric population where childhood behaviors may reduce risk of disease later in life. We draw from the adult melanoma genetic risk communication and pediatric health behavior change literatures to suggest ways in which genetic test reporting and complementary education could be delivered to children who carry a hereditary risk for melanoma and their families in order to foster children's engagement in melanoma preventive behaviors. Genetic discoveries will continue to yield new opportunities to provide predispositional genetic risk information to unaffected individuals, including children, and could be delivered within programs that provide personalized and translational approaches to cancer prevention.

Correlates of Sun Protection and Sunburn in Children of Melanoma Survivors

INTRODUCTION

Sunburns during childhood increase melanoma risk. Children of melanoma survivors are at higher risk, but little is known about their sunburn and sun protection. One study showed that almost half of melanoma survivors' children experienced sunburn in the past year. This study evaluated sunburn and sun protection in melanoma survivors' children, and relevant survivor characteristics from Social Cognitive Theory and the Health Belief Model.

METHODS

Melanoma survivors (N=340) were recruited from a comprehensive cancer center. Survivors completed a baseline questionnaire administered by telephone to report on the behavior of their children (N=340) as part of an RCT of a sun protection intervention. Data were collected in 2008 and analyzed in 2015.

RESULTS

In the prior 6 months, 28% of children experienced sunburn. "Always" or "frequent" sun protection varied by behavior: sunscreen, 69%; lip balm, 15%; wide-brimmed hats, 9%; sleeved shirts, 28%; pants, 48%; sunglasses, 10%; shade, 33%; and limiting time outdoors, 45%. Survivors' sunburn and sun protection were positively associated with these outcomes in children. Correlates of sunburn also included older child age and higher risk perceptions. Correlates of sun protection behaviors included younger child age; stronger intentions, higher self-efficacy, and more positive outcome expectations about sun protection; and greater number of melanomas in survivors.

CONCLUSIONS

Melanoma survivors may have a heightened awareness of the importance of their children's sun protection, but their children are not routinely protected. Correlates of children's sunburn and sun protection suggest subgroups of survivors to target with interventions to improve sun protection.

Ultraviolet Radiation Exposure and Its Impact on Skin Cancer Risk

OBJECTIVES

To review research and evidence-based resources on skin cancer prevention and early detection and their importance for oncology nurses.

DATA SOURCES

Journal articles, federal reports, cancer surveillance data, behavioral surveillance data.

CONCLUSION

Most cases of skin cancer are preventable. Survivors of many types of cancer are at increased risk of skin cancers.

IMPLICATIONS FOR NURSING PRACTICE

Oncology nurses can play an important role in protecting their patients from future skin cancer morbidity and mortality.

A systematic review of interventions to improve adherence to melanoma preventive behaviors for individuals at elevated risk

BACKGROUND AND OBJECTIVES

To examine the effectiveness of behavioral interventions for melanoma prevention targeted to individuals at elevated risk due to personal and/or family history.

METHODS

Through literature searches in 5 search databases (through July 2014), 20 articles describing 14 unique interventions focused on melanoma prevention among individuals at elevated risk for the disease were identified. Interventions targeting only patients undergoing active treatment for melanoma were excluded.

RESULTS

The average study quality was moderate. The majority of interventions (6 out of 9, 66% of studies) led to improvements in one or more photoprotective behaviors, particularly for improvements in use of protective clothing (3 out of 5, 60% of studies), and frequency and/or thoroughness of skin self-examinations (9 out of 12, 75%). Fewer interventions (5 out of 14, 36%) targeted uptake of total body skin examinations (60% led to improvements). Also, fewer interventions targeted all three preventive behaviors (5 out of 14, 36%).

CONCLUSIONS

Findings suggest that future interventions should aim to improve adherence across multiple preventive behaviors, over a longer time period (past 8months post-intervention), and target high-risk children. Studies should include adequate sample sizes to investigate moderators and mediators of intervention effectiveness. Interventions may be strengthened by new techniques, such as incorporating family members (e.g., to improve thoroughness of skin self-examinations) and eHealth technology.

Melanoma Epidemiology and Prevention

The epidemiology of melanoma is complex, and individual risk depends on sun exposure, host factors, and genetic factors, and in their interactions as well. Sun exposure can be classified as intermittent, chronic, or cumulative (overall) exposure, and each appears to have a different effect on type of melanoma. Other environmental factors, such as chemical exposures-either through occupation, atmosphere, or food-may increase risk for melanoma, and this area warrants further study. Host factors that are well known to be important are the numbers and types of nevi and the skin phenotype. Genetic factors are classified as high-penetrant genes, moderate-risk genes, or low-risk genetic polymorphisms. Subtypes of tumors, such as BRAF-mutated tumors, have different risk factors as well as different therapies. Prevention of melanoma has been attempted using various strategies in specific subpopulations, but to date optimal interventions to reduce incidence have not emerged.

Sun protection practices and sun exposure among children with a parental history of melanoma

BACKGROUND

First-degree relatives of melanoma survivors have a substantially higher lifetime risk for melanoma than individuals with no family history. Exposure to ultraviolet radiation (UVR) is the primary modifiable risk factor for the disease. Reducing UV exposure through sun protection may be particularly important for children with a parental history of melanoma. Nonetheless, limited prior research has investigated sun protection practices and sun exposure among these children.

METHODS

The California Cancer Registry was used to identify melanoma survivors eligible to participate in a survey to assess their children's sun protection practices and sun exposure. The survey was administered by mail, telephone, or web to Latino and non-Latino white melanoma survivors with at least one child (0-17 years; N = 324).

RESULTS

Sun exposure was high and the rate of sunburn was equivalent to or higher than estimates from average-risk populations. Use of sun protection was suboptimal. Latino children were less likely to wear sunscreen and hats and more likely to wear sunglasses, although these differences disappeared in adjusted analyses. Increasing age of the child was associated with lower sun protection and higher risk for sunburn, whereas higher objective risk for melanoma predicted improved sun protection and a higher risk for sunburns. Perception of high barriers to sun protection was the strongest modifiable correlate of sun protection.

CONCLUSIONS

Interventions to improve sun protection and reduce sun exposure and sunburns in high-risk children are needed.

IMPACT

Intervening in high-risk populations may help reduce the burden of melanoma in the United States.

Transtheoretical Model Constructs' Longitudinal Prediction of Sun Protection Over 24 Months

PURPOSE

This research examined dynamic transtheoretical model (TTM) constructs for adopting sun protection practices. This secondary data analysis pooled four large population-based TTM-tailored intervention studies and examined use of constructs across three groups, organized by longitudinal progress: maintainers, relapsers, and stable non-changers.

METHODS

A total of 3463 adults, in the USA, who met criteria for unsafe sun exposure at baseline received a TTM-tailored computerized intervention at baseline, 6 months, and 12 months. The final analytic sample consisted of 1894 participants; the majority were female, White, married, and middle-aged. The three groups were assessed with reliable and valid scales assessing use of TTM constructs at baseline, 6 months, 12 months, and 24 months. Analyses included a MANOVA followed by a series of ANOVAs, with Tukey follow-up tests assessing differences in use of TTM constructs across the three groups at each timepoint.

RESULTS

Findings demonstrated that relapsers and maintainers were similar in their use of most TTM processes of change at baseline, with the exception of Consciousness Raising, Stimulus Control, Reinforcement Management, and Self-Liberation.

CONCLUSIONS

These findings suggest that although relapsers reverted to unsafe sun practices, their overall greater use of processes of change indicates that their change efforts remain better than that of stable non-changers.

Effects of web-based intervention on risk reduction behaviors in melanoma survivors

PURPOSE

Melanoma is the most severe form of skin cancer, and survivors of melanoma carry increased risk of additional melanoma diagnosis. Multiple methods exist for primary and secondary prevention of melanoma in survivors. This study tested a web-based family communication intervention to improve these preventive behaviors in melanoma families.

METHODS

Families (a survivor, at least one first-degree relative and a parent) were randomized either to receive the intervention package or to serve as comparison families. We assessed melanoma prevention behaviors in each cohort member before and after the intervention. The intervention was a web-based multicomponent intervention focused on increasing family communication and exchange of risk information.

RESULTS

Results indicated that, compared to comparison survivors, intervention survivors improved their skin self-examination and their sun protection behaviors significantly from before to after intervention.

CONCLUSION

These data support the use of web-based interventions for behavioral changes in survivors and allow for consideration of dissemination of this successful intervention. These data have implications for interventions that can help cancer families deal with issues of risk and illness.

IMPLICATIONS FOR CANCER SURVIVORS

These data indicate that survivors can benefit from exposure to a website that helps direct their future health behaviors.
