Changing patterns of sun protection between the first and second summers for very young children.

OBJECTIVES: To determine if an intensive intervention directed to mothers of newborns would increase levels of sun protection practice and lower rates of sunburning for their children; and to examine changes in sun protection practices and burning rates experienced between the first and second summers of life. DESIGN: Randomized study. SETTING AND PARTICIPANTS: Mothers of infants residing in the coastal town of Falmouth, Mass. INTERVENTION: Mothers were randomly selected to receive hospital education alone or hospital education plus tailored materials and telephone counseling. MAIN OUTCOME MEASURES: Child's sun protection practices and degree of skin damage at mean ages 6 and 18 months, as reported by the mother. RESULTS: Baseline surveys were completed by 108 mothers; 92 (85%) of the mothers completed posttests. There were few differences between intervention and control groups in use of sun protection for infants from the first summer (mean age, 6 months) to the second summer (mean age, 18 months). The child's routine use of hats, shirts, and shade dropped substantially from the first to the second summer. Conversely, sunscreen use rose from 34% to 93% (P<.001) for both groups during the same period. During the first summer, 22% of children received a sunburn or tan compared with 54% during the second summer (P<.001). CONCLUSIONS: Comprehensive sun protection begins to decline at a much earlier age than previously reported. Future studies should focus on parents' beliefs about the need for, and practice of, vigilant sun protection as their children grow from infancy to toddlerhood.

What's in store for medical students? Awareness and utilization of expert nutrition guidelines among medical school preceptors.

BACKGROUND: Instruction of physicians and other health professionals in medical nutrition sciences is among the expert recommendations to promote population health and reduce risks for cancer and other major causes of morbidity and mortality in the population. However, formal training in nutrition in United States medical schools is still lacking compared to the gains in basic and applied medical nutrition sciences. We sought to understand the awareness and current utilization of expert nutrition recommendations and practice guidelines among medical student faculty preceptors. METHODS: We surveyed the teaching faculty who precept for first-, second-, and third-year medical students in two required courses at Boston University. The instrument queried preceptor awareness and current utilization of expert nutrition recommendations, nutritional management practice guidelines, as well as faculty-student interactions regarding patient nutritional education and counseling. RESULTS: Of 187 faculty surveyed, 139 (74%) responded. Faculty reported using 2.3 expert guideline sources (N = 111; SD = 1.8; range = 0-8) but 83% had considered only one or no sources or did not remember what guidelines they had used. Eighty-four percent of preceptors expected students to routinely discuss nutritional practices with patients and/or their families; however, less than half of preceptors routinely provided feedback to students on patient nutritional education or counseling strategies. CONCLUSION: Our findings suggest gaps in faculty awareness and utilization of expert nutrition recommendations and practice guidelines relating to cancer and other chronic disease-risk reduction and population health promotion, underscoring the need for improvements in faculty and medical student training in basic and applied medical nutrition sciences.

Evaluation of current tobacco curriculum at 12 US medical schools.

BACKGROUND: Training medical students in tobacco prevention and treatment skills is critical if we are to have competent physicians prepared to address the grave levels of morbidity and mortality associated with tobacco use. Tobacco Prevention and Cessation Education at US Medical Schools (PACE), a National Cancer Institute funded project, was launched to assess and improve curriculum content and teaching at 12 US medical schools. METHODS: The 2003 survey was completed by faculty and administrators. The survey was divided into four main sections: tobacco content and skills, curricular evaluation, faculty perceptions of barriers and promoters, and educational vision. RESULTS: Thirty-six percent of all medical school courses had some tobacco-related content. Five schools provided a total of between 4 and 8 hours of teaching, 5 schools provided 10-13 hours, and 2 schools provided 17 and 18 hours of teaching. Of the 12 schools, 8 had fewer hours devoted to tobacco teaching in the clerkships than during the 1st-year courses. Only 2 schools noted any tobacco content for Obstetrics/Gynecology clerkships, and only 4 schools provided teaching in the pediatric setting (range 5-201 minutes). CONCLUSION: In comparison to earlier studies, it appears that more tobacco content is now integrated into medical school courses. More improvement is necessary, however, particularly in tobacco use prevention. Institutions need to examine the role of faculty in prioritizing tobacco information and promoting a culture that builds competency in tobacco control and treatment.

Melanoma in the older person.

Melanoma accounts for the majority of skin cancer deaths worldwide and has dramatically increased in incidence over the past half-century. Despite recent trends showing improved survival, and stabilization of incidence rates in younger Americans, melanoma incidence and mortality continue to rise unabated in older individuals, particularly in men over age 65. Efforts at early clinical detection of melanoma in older individuals should take into account the differences in melanoma subtypes in older individuals, potentially reduced access to medical specialists in this population, as well as comorbidities that may affect ability to undergo treatment for advanced disease. Secondary melanoma prevention should be focused on targeted education to older men and their spouses for early detection and reduction of mortality in this extremely high-risk group.

Can an hour or two of sun protection education keep the sunburn away? Evaluation of the Environmental Protection Agency's Sunwise School Program.

BACKGROUND: Melanoma incidence is rising at a rate faster than any other preventable cancer in the United States. Childhood exposure to ultraviolet (UV) light increases risk for skin cancer as an adult, thus starting positive sun protection habits early may be key to reducing the incidence of this disease. METHODS: The Environmental Protection Agency's SunWise School Program, a national environmental and health education program for sun safety of children in primary and secondary schools (grades K-8), was evaluated with surveys administered to participating students and faculty. RESULTS: Pretests (n = 5,625) and posttests (n = 5,028) were completed by students in 102 schools in 42 states. Significant improvement was noted for the three knowledge variables. Intentions to play in the shade increased from 68% to 75%(p < 0.001) with more modest changes in intentions to use sunscreen. Attitudes regarding healthiness of a tan also decreased significantly. CONCLUSIONS: Brief, standardized sun protection education can be efficiently interwoven into existing school curricula, and result in improvements in knowledge and positive intentions for sun protection.

Epidemiology of melanoma and nonmelanoma skin cancer.

OBJECTIVES: To describe the epidemiology of melanoma and nonmelanoma skin cancers. DATA SOURCES: Review and research articles, book chapters, and Surveillance, Epidemiology, and End Results (SEER) data. CONCLUSIONS: In 2002, an estimated 1.3 million Americans were diagnosed with skin cancer. Of these, 53,000 individuals were diagnosed with melanoma, the most common fatal form of skin cancer, and more than 7,000 Americans died of melanoma. Nonmelanoma skin cancer has the highest incidence of all cancers and the rise in the rate of cutaneous melanoma exceeds all other preventable cancers. IMPLICATIONS FOR NURSING PRACTICE: Nurses can act as case-finders and as advocates and educators for prevention of overexposure to ultraviolet radiation. Nurses should ascertain possible inherited risk and monitor patients for additional primary skin cancers.

The first 15 years of the American Academy of Dermatology skin cancer screening programs: 1985-1999.

BACKGROUND: In response to the precipitous increase of melanoma, the American Academy of Dermatology (AAD) has coupled melanoma/skin cancer education with free skin cancer screening programs throughout the United States since 1985. The purpose of this analysis is to investigate the risk factors, access to dermatologic services, and screening results of participants in AAD-sponsored programs during the first 15 years that this service was available to the US public. METHODS: Before screening, participants completed a standardized AAD screening form. Screening forms were counted in the AAD central office and recorded in annual summaries. Forms were sent for keypunching and returned to the AAD on a computer disk annually. In 1999, disks were sent to Boston University and a master file was created. RESULTS: Computerized records were available for 819,019 screening forms and 639,835 individuals. In all, 65% of screenees had at least 1 risk factor and 33% had at least 2 risk factors. Of screenees, 33% reported a changing mole and 37% had skin type I or II. Among all screenees, nearly 80% did not have a regular dermatologist, 78% reported no prior AAD skin cancer screening, 60% had never had their skin checked by any doctor, and 51% would not have seen a doctor for skin cancer without the free screening. Nearly 30% of screenees had a presumptive diagnosis of skin cancer or a precursor lesion. Melanomas confirmed by postscreening biopsy were more likely than those in population-based registries to be less than 1.50 mm in thickness. CONCLUSIONS: AAD national screening and educational programs have expanded to all 50 states, provided educational messages about sun protection and early detection to millions, and served many US citizens with an above average risk for skin cancer and suboptimal access to dermatologic care. Screenees had a disturbingly high point prevalence of malignant and premalignant skin lesions. Sustained commitment by the AAD leadership and membership to the screening program is critical to reducing the morbidity and mortality of skin cancer.

Sunburn reduction through parental role modeling and sunscreen vigilance.

OBJECTIVES: To identify characteristics associated with child sunburn experience and sun protection practices, including parent and child demographics, phenotype, and sun-related knowledge, attitudes, and behaviors. STUDY DESIGN: A nationally representative telephone survey conducted in 1999 with 651 parents of children 5 to 12 years of age to collect data relating to the sun-related knowledge, attitudes, and behaviors of the parent and child. RESULTS: Nearly half of parents (49%) and children (44%) were sunburnt during the previous summer. Parents who reported that they had been sunburnt were more likely to have children who had been sunburnt (OR = 2.9, 95% CI = 2.0, 4.2). Conversely, parents with a high level of sun protection behavior were less likely to report being sunburnt (OR = 0.6, 95% CI = 0.4, 0.9), and their children were more likely to have a high level of sun protection behavior (OR = 3.0, 95% CI = 2.0, 4.6) and sunscreen vigilance (OR = 2.7, 95% CI = 1.7, 4.5). High sunscreen vigilance was associated with a 60% reduction in child sunburning. CONCLUSIONS: The sunburn experience and sun protection practices of children (5-12 years of age) are closely linked to a number of modifiable attitudes and behaviors of their parents. Therefore the inclusion of parents and care givers in interventions targeting children may increase program efficacy.

Skin cancer prevention and detection practices among siblings of patients with melanoma.

BACKGROUND: Family members of patients with melanoma have an increased risk of the disease, and families with multiple affected members account for about 10% of melanoma cases. These statistics suggest that first-degree relatives of patients with melanoma, who are at particularly high risk, warrant targeted public health action. OBJECTIVE: We sought to document rates for dermatologist examinations for cutaneous lesions, the practice of skin self-examination, and sunscreen use in this at-risk group. METHODS: Before participation in a randomized trial, 404 siblings of recently diagnosed patients with melanoma completed a survey on beliefs and practices regarding skin cancer prevention and detection. RESULTS: Sixty-two percent of participants had carefully examined their skin, 54% routinely used sunscreen, and 27% had received a skin cancer examination by a dermatologist during the past year; 47% had never received a dermatologist examination. Multivariate analysis found modifiable positive predictors for skin self-examination and dermatologist examinations, including having a clinician with whom to talk about melanoma and believing in the importance of regular skin examinations by a physician. Significant modifiable negative predictors included enjoyment of being tanned, not being sure what to look for when examining moles, and feeling uncomfortable having others look at their skin. CONCLUSIONS: Skin self-examination rates among these high-risk siblings are markedly higher than in population-based studies. However, many siblings were not screened for skin cancer by a dermatologist despite having strong risk profiles, being nearly fully insured, and being under care of primary care physicians. Improvements in communication between physicians and high-risk families and changes in office systems to assess family history of melanoma could increase screening rates for the estimated 1 million siblings of patients with melanoma.

Gender differences in young adults' beliefs about sunscreen use.

This study employs focus group methodology to explore gender differences in sunscreen use. Guided by the theory of reasoned action, males and females were found to differ on each of the following constructs: behavior, behavioral beliefs, and normative beliefs. Males and females differed in their sunscreen use, with females adopting a more preventive style of sunscreen use and males a more reactive style. Males and females differed in their salient beliefs that motivated their sunscreen use, many of which were related to traditional American gender roles. In addition, although males and females were aware of both positive and negative sources of normative beliefs regarding sunscreen use, females received more encouragement from their mothers and peers than males. Findings are discussed in terms of their implications for the design of future interventions.

Strategies for improving melanoma education and screening for men age >or= 50 years: findings from the American Academy of Dermatological National Skin Cancer Sreening Program.

BACKGROUND: Recently, the Institute of Medicine (2000) and the Third United States Preventive Services Task Force (2001) called for studies to help clinicians identify patients, especially elderly patients, who are at high risk for melanoma. In the current study, the authors sought to identify factors associated with a high yield in skin cancer screening and to explore strategies for improving mass screenings for melanoma. METHODS: The authors analyzed the data base of the 242,374 skin cancer screenings conducted on more than 206,000 Americans who attended the American Academy of Dermatology National Skin Cancer Screening Programs during the period 1992-1994. RESULTS: Ninety-six percent of 3476 screenees with a presumptive diagnosis of melanoma or possible melanoma were contacted, and follow-up records were obtained for 73% of screenees. Of these, 363 screenees had histologically proven melanoma. Middle-aged and older men (age >or= 50 years) comprised only 25% of screenees but comprised 44% of those with a confirmed diagnosis of melanoma. The overall yield of melanoma (the number of confirmed diagnoses per the number of screenees) was 1.5 per 1000 screenings (363 diagnoses of 242,374 screenees) compared with a yield of 2.6 per 1000 screenings among men age >or= 50 years. The yield was improved further for men age >or= 50 years who reported either a changing mole (4.6 per 1000 screenings) or skin types I and II (3.8 per 1000 screenings). The predictive value of a screening diagnosis of melanoma was more than twice as high for men age >or= 50 years with either a changing mole or skin types I and II compared with all other participants. CONCLUSIONS: The yield of mass screening for melanoma would be improved by outreach to middle-aged and older men, with particular focus on men with changing moles or with skin types I and II. Primary care physicians should be attuned to the risk factors among all of their patients but should be alerted in particular to the heightened risk of melanoma for men age >or= 50 years. Formal assessment of the impact of targeted screening on mortality warrants further study.

Sun protection policies and environmental features in US elementary schools.

OBJECTIVE: To assess current sun protection policies and the receptiveness to new policies at elementary schools in the United States. DESIGN: A cross-sectional telephone survey. SETTING: General educational community. PATIENTS OR OTHER PARTICIPANTS: In 1998, a random sample of 1000 public elementary schools in the United States was selected (proportional to population size) from 27 metropolitan areas chosen from the 58 US cities regularly reporting the UV index in 1997. A final sample of principals from 412 elementary schools completed the survey. INTERVENTION: None. MAIN OUTCOME MEASURES: Only 3.4% of schools had a sun protection policy. The most common reasons for not having a policy included the principal's lack of awareness (n = 113) or organizational barriers in the school districts (n = 77). Most principals (84.2%) said that students were outdoors during midday hours. Many principals (48.3%) were willing to adopt a sun protection policy. Most schools (72.8%) had shade structures but the majority (67.3%) reportedly covered less than one fifth of the grounds. Most principals (76.4%) were willing to increase the amount of shade structures. CONCLUSIONS: The low frequency of sun protection policies and shade structures calls for national efforts to change policies and environments to increase sun protection at US schools. Research is needed to demonstrate the efficacy of these changes.

Should the skin cancer examination be taught in medical school?

BACKGROUND: The fact that thin melanomas are associated with a greater than 95% survival rate, while later, more deeply invasive melanomas have a 5-year survival rate of less than 10%, demonstrates the potential personal and public health impact of early detection. The majority of patients with skin lesions are seen by nondermatologists who infrequently counsel patients about skin cancer prevention or perform a complete skin examination as part of routine care. We documented the antecedents of physician practice by evaluating medical students' observation, training, performance, and self-reported skill level for the skin cancer examination and sun protection counseling. METHODS: Surveys were administered and completed in classrooms and student workshops in each of the 4 medical school years during the spring of 1996 and 1997. We concentrate our analysis on the graduating fourth-year students. RESULTS: Of the 302 fourth-year students enrolled at Boston University School of Medicine, Boston, Mass, in 1996 and 1997, 223 (74%) completed surveys. Among fourth-year students, 52% rated themselves as unskilled in skin cancer examinations. Twenty-eight percent of fourth-year students had never observed a skin cancer examination, 40% had received no training, and 35% had never practiced the examination. However, fourth-year students reporting at least 1 opportunity to observe, train, or practice an examination were 3 times as likely to report themselves as moderately to very skilled as students without such opportunities. CONCLUSION: If medical student training rates for the skin cancer examination are equally low elsewhere, as is likely, the present data suggest that even brief additions to the current curriculum, integrated into systems teaching, would augment student exposure and likely boost student skill levels.

Evaluation of a cancer prevention and detection curriculum for medical students.

BACKGROUND: Undergraduate medical education needs revision to ensure that medical students graduate with the skills necessary to assist their patients in cancer prevention and detection. We sought to implement and incorporate a cancer education curriculum into the students' core curriculum and to assess their skill levels prior to (1996), during (1997), and at the peak (1998-1999) of the incorporation of new hours. METHODS: We conducted pretest and posttest surveys of students at Boston University School of Medicine (medical student years 1-4) enrolled in each of the four study years (1996-1999). A total of 1,956 surveys (response rate, 82%) were completed. The primary outcome measure was the student's self-reported skill level (with responses ranging from 1 (very unskilled) to 5 (very skilled)) for counseling for tobacco cessation, tobacco prevention, and sun protection and for the early detection of breast, skin, and cervical cancer. Mean scores were computed for each chronological year of the study and medical school year. Differences and trends over time in mean scores of students in each medical school year were evaluated using multiple regression analysis. RESULTS: The number of hours of cancer education increased from 6 in 1996 to 15 in 1999. Strong improvements in self-rated skill levels were recorded for four of the six measures. In particular, tobacco cessation counseling skill rose from 2.16 (1996) to 3.13 (1999) for second year students (P < 0.001) and from 3.27 (1996) to 4.17 (1999) for fourth year students (P < 0.001). Among fourth year students, the percentage reporting that cancer prevention was given too little emphasis declined from 62% (1996) to 26% (1999) (P < 0.001), suggesting that the expanded curriculum reflected the students' preferences. CONCLUSIONS: Cancer education can be interwoven into the existing medical school curriculum and produce improvements in students' skill levels for counseling and examinations. Strategies to enhance prevention teaching can use this model.

The Environmental Protection Agency's National SunWise School Program: sun protection education in US schools (1999-2000).

BACKGROUND: Melanoma, the most fatal form of skin cancer, is rising at a rate faster than that of all preventable cancers except lung cancer in the United States. Childhood exposure to ultraviolet (UV) light increases the risk for skin cancer as an adult; thus starting positive sun protection habits early may be key to reducing incidence. METHODS: We evaluated the US Environmental Protection Agency's SunWise School Program, a national, environmental education program for sun safety of children in primary and secondary schools (kindergarten through eighth grade). The program was evaluated with surveys administered to participating students. An identical 18-question, self-administered survey was completed by students (median age, 10 years) in the classroom before and immediately after the SunWise educational program. RESULTS: Surveys were completed by students in 40 schools before (pretests; n = 1894) and after the program was presented (post-tests; n = 1815). Significant improvement was noted for the 3 knowledge variables: appropriate type of sunscreen to be used for outdoor play, highest UV Index number, and need for hats and shirts outside. Intentions to play in the shade increased from 73% to 78% (P <.001), with more modest changes in intentions to use sunscreen. Attitudes regarding healthiness of a tan also decreased significantly. CONCLUSIONS: Brief, standardized sun protection education can be efficiently interwoven into school health education and result in improvements in knowledge and positive intentions for sun protection.
