Children's skin cancer prevention: a systematic review of parents' psychosocial measures

CONTEXT

Parents' knowledge, attitudes, and beliefs may be influenced through intervention to increase children's sun protection. Little is known about measures of these psychosocial characteristics, including psychometric properties. This paper systematically reviews parents' psychosocial measures in children's skin cancer prevention studies.

EVIDENCE ACQUISITION

A search of standard databases conducted in 2008, updated in 2011, yielded 5797 unique citations. A study was eligible if (1) it was published between January 1980 and March 2011; (2) it was published in English; (3) it reported a psychosocial measure relevant to children's skin cancer prevention; and (4) the psychosocial measure was administered to parents, the majority of whom had children aged ≤12 years. Screening yielded 57 eligible studies. Data were analyzed in 2008 and 2011.

EVIDENCE SYNTHESIS

Most studies measured one (n=24) or two (n=18) psychosocial constructs; few (n=7) measured more than three. The most frequently measured constructs were knowledge (n=41); attitudes (n=22); perceived susceptibility/risk (n=11); self-efficacy (n=9); and perceived barriers (n=9). Most studies did not mention theory. Theoretic mechanisms underlying interventions were not examined. There was little description of measure validity. Reliability, usually internal consistency, was reported more often (n=19).

CONCLUSIONS

Few studies assessed more than two parent-related psychosocial constructs, so it was not possible to test theoretic models of parental influences on children's sun protection. Validated measures were lacking. There was conceptual overlap of measures because of the presence of analogous constructs across theories and assessment of multiple constructs within a single measure.

Sun-care product advertising in parenting magazines: what information does it provide about sun protection?

This study analyzed the content of sun-care product advertisements in five major U.S. parenting magazines with high circulation: Family Circle, Parents, Family Fun, Parenting (Early Years), and Parenting (School Years). The study examined what information sun-care product advertisements tell parents about skin cancer prevention and about sunscreen use for themselves or for their children based on the Health Belief Model concepts of perceived benefits and perceived barriers. Results showed that the most commonly mentioned benefit of the product was that it blocks ultraviolet A (UVA) and ultraviolet B (UVB) rays. One-third of the ads promoted the product's effectiveness in overcoming four of the barriers that prevent people from using sunscreens: eye irritation, skin irritation, an unpleasant smell, and the need to reapply sunscreen too often or after physical activity. However, only a few of the ads provided information about the consequences of unprotected sun exposure or mentioned methods of sun protection or skin cancer prevention other than sunscreen use. We discuss the implications of these messages for parents' ability to understand correctly how to protect their children from damaging sun exposure.

A randomized intervention study of sun protection promotion in well-child care

BACKGROUND

This study evaluated the behavioral impact of a skin cancer prevention program in which health care providers delivered advice and materials to parents of infants over a 3-year period from 1998 to 2001.

METHODS

Fourteen offices of a large managed care organization in Colorado were randomly assigned to the intervention or control groups. 728 infants and their parents were recruited within 6 months of birth. At intervention offices, health care providers attended orientation sessions, prompts for delivering sun protection advice were placed in medical records, and parents received sun protection packets at each well-child visit between 2 and 36 months of age.

RESULTS

Based on provider self-report and exit interviews of parents, providers in the intervention group delivered approximately twice as much sun protection advice as providers in the control group. Annual telephone interviews of parents indicated small but statistically significant differences in parent sun protection practices favoring the intervention. Skin exams revealed no significant differences in tanning, freckling, or number of nevi. Behavioral differences between groups appeared to grow over the 3 years of follow-up.

CONCLUSIONS

This intervention strategy was successful in increasing the delivery of sun protection advice by health care providers and resulted in changes in parents' behaviors. While the behavioral effect was probably not strong enough to reduce risk for skin cancer, the effect may increase as children age and have more opportunities for overexposure to the sun.

Public health challenges in sun protection

Sunscreens are a popular choice for protection from ultraviolet radiation, and hence, important components in the public health campaign to reduce the burden of skin cancer. Public health messages in skin cancer prevention have been used effectively in educational campaigns. The benefits of sunscreen extend beyond skin cancer prevention into other aspects of health and disease prevention: sunscreen decreases the risk for sunburn during physical activity outdoors and seems not to increase the risk for osteoporosis. Public health efforts have laid a solid foundation on which to face the continuing challenge of promoting and developing effective public health campaigns and health policies that encourage sunscreen use, sun protection, and the primary prevention of skin cancer. In this article, the controversies, concerns, and challenges of sunscreen use as it relates to public health are discussed.

Melanoma and ionizing radiation: is there a causal relationship?

This review was initiated in response to concerns that ionizing radiation could be a cause of melanoma. Studies presenting the relative risks for melanoma after external ionizing radiation exposure were in seven categories: (1) The Canadian Radiation Dose Registry, (2) nuclear industry workers, (3) subjects near nuclear test blasts, (4) survivors of the atomic bombings of Japan, (5) airline pilots and cabin attendants, (6) recipients of medical radiation, and (7) radiological technicians. Relative risks for leukemia in each of the studies were used to confirm the likelihood of exposure to ionizing radiation. When studies within a category were compatible, meta-analytic methods were used to obtain combined estimates of the relative risk, and a meta-regression analysis of melanoma relative risk compared to leukemia relative risk was used to examine consistency across exposure categories. Generally, exposure categories with elevated relative risks of leukemia had proportionately elevated relative risks of melanoma. This suggests that people exposed to ionizing radiation may be at increased risk of developing melanoma, although alternative explanations are possible. Future epidemiological studies of ionizing radiation effects should include melanoma as an outcome of interest.

[Prevention of skin cancer programs: analysis of the impact of randomized trials]

INTRODUCTION

Exposure to ultraviolet sun rays is an important risk factor for the development of skin cancer. Confronted with the increase in the incidence of severe forms (melanoma), primary prevention plays a major part, together with the development of campaigns promoting individual and collective protection against ultraviolet rays.

OBJECTIVE

The aim of this trial was to identify the factors of success or failure of skin cancer prevention programs and to analyze their impact.

METHOD

Articles published in the literature from 1982 to 2002 were selected from the Medline databank using the following key words: "skin cancer, melanoma, evaluation, prevention and education, review, program, campaign and randomized controlled trial". For the final analysis, only the randomized trials with control group were retained.

RESULTS

All the prevention programs increased short, median or long term knowledge. Conversely, the trials were sometimes contradicting with regard to the change in attitude. No methodologically correct trial clearly reported any change in behavior, the majority of them only collected intent behavior.

CONCLUSION

Despite the methodological weaknesses of most of the trials published, this review of the literature underlined certain points. The most efficient programs appear to be those targeting children, the training sessions of which are long and/or repeated, with active individual participation. Programs based on the deleterious consequences of sun exposure on physical appearance appeared to produce better results in terms of any change in attitude and intent behavior.

Interventions to prevent skin cancer by reducing exposure to ultraviolet radiation: a systematic review

The relationship between skin cancer and ultraviolet radiation is well established. Behaviors such as seeking shade, avoiding sun exposure during peak hours of radiation, wearing protective clothing, or some combination of these behaviors can provide protection. Sunscreen use alone is not considered an adequate protection against ultraviolet radiation. This report presents the results of systematic reviews of effectiveness, applicability, other harms or benefits, economic evaluations, and barriers to use of selected interventions to prevent skin cancer by reducing exposure to ultraviolet radiation. The Task Force on Community Preventive Services found that education and policy approaches to increasing sun-protective behaviors were effective when implemented in primary schools and in recreational or tourism settings, but found insufficient evidence to determine effectiveness when implemented in other settings, such as child care centers, secondary schools and colleges, and occupational settings. They also found insufficient evidence to determine the effectiveness of interventions oriented to healthcare settings and providers, media campaigns alone, interventions oriented to parents or caregivers of children, and community-wide multicomponent interventions. The report also provides suggestions for areas for future research.

Sunburn in children -- the Aberdeen experience

Sun exposure in children is known to be a risk factor for the development of malignant melanoma in later life. The incidence of melanoma in the UK is increasing more rapidly than that of most other malignant tumours and there is now increasing awareness in adults of the necessity to protect against over-exposure and sunburn. However sun protection of children in the UK is generally less than optimum and it would appear that parents and children are unaware of the long-term risks of over-exposure to the sun. This study demonstrates significant morbidity from sunburn even in the temperate climes of the north-east of Scotland. It is suggested that strategies to reduce melanoma incidence should begin at an early age with preventative education for children, their parents, carers and teachers.
