This study examined cognitions relevant to sunbathing decision-making in college-aged subjects. Using Jaccard's (1981) theory of alternative behavior as a guiding model, 263 subjects were recruited from psychology classes and administered questionnaires assessing their sunbathing behavioral tendencies, attitudes toward sunbathing, attitudes toward reasonable behavioral alternatives to sunbathing, and cognitive variables underlying these attitudinal variables. The fits of models predicting sunbathing attitudes and sunbathing behavioral tendencies (evaluated using covariate structural equations modeling techniques; LISREL VIII) were good for all models tested. In contrast to previous work, the results of this study support the notion that young people will make their decisions regarding sunbathing based on the behavioral alternatives available to them (i.e., generally the one that they prefer most). Furthermore, the multivariate approach used clearly delineates the specific cognitive beliefs and orientations that might be targeted to change these attitudes. The relevance of these findings to skin cancer prevention interventions is discussed.

Ajzen's (1988) theory of planned behavior (TOPB) was used to examine psychological determinants of high-risk UV radiation exposure-related behaviors (sunbathing, tanning salon use, and sunscreen use). Undergraduates at a midsized southeastern university were assessed on their psychological and behavioral tendencies toward high-risk UV radiation exposure-related behaviors. The results generally supported the utility of the TOPB as an explanatory model for high-risk behavior. Attitudes were strongly associated with high-risk intentions (e.g., not utilize sunscreen, use salons), whereas subjective norms were less so. Perceived behavioral control was found to moderate the relationship among attitudes, norms, and intentions to sunbathe and tan at a salon. Implications for intervention strategies and future model building in this area are discussed.

Introdução: Uma elevada prevalência de deficiência de vitamina D (DVD) em crianças tem sido observada em todo o mundo, mas poucos são os estudos com relação ao estado nutricional da vitamina D (VD) em lactentes saudáveis. A principal causa da deficiência em crianças saudáveis é o aleitamento materno sem suplementação e a falta ou insuficiência de exposição solar. Objetivos: Determinar as concentrações séricas de VD e verificar sua associação com concentrações de paratormônio (PTH), fosfatase alcalina (FA), cálcio (Ca), fósforo (P) e albumina e uso da suplementação de VD em lactentes saudáveis com idades entre >= 6 e <= 24 meses atendidos em duas Unidades Básicas de Saúde do município de Ribeirão Preto, SP, Brasil. Métodos: Estudo transversal, observacional e analítico em que foram determinadas as concentrações séricas de 25 (OH)D, PTH, FA, Ca, P e albumina de 155 lactentes saudáveis. Informações sobre exposição solar, aspectos sociodemográficos das mães e características clínico-nutricionais dos lactentes foram obtidas por entrevistas com os responsáveis dos lactentes. Concentrações séricas de 25(OH)D maiores que 20ng/ml foram consideradas adequadas, entre 12 a 20ng/ml insuficientes e < 12ng/ml deficientes. Resultados: Dez lactentes (6,5%, Intervalo de Confiança 95% 3,5-11,4) apresentaram insuficiência de VD e nenhum apresentou DVD. Nenhuma alteração nas concentrações séricas de P, Ca e albumina foram detectadas. Apenas um lactente apresentou aumento nas concentrações séricas de PTH e 35,5% dos lactentes apresentaram FA elevada, porém nenhum apresentou DVD ou insuficiência de VD. Não foram encontradas associações entre as concentrações séricas de 25(OH)D e as de FA, Ca e albumina. Houve associação entre concentrações séricas de 25(OH)D e PTH mesmo após ajuste para sexo, idade e Índice de Massa Corporal; também foi observada associação entre concentrações séricas de 25(OH)D e P apenas após o ajuste pelas covariáveis. Não foram verificadas associações entre insuficiência de VD, exposição solar e suplementação de VD. Conclusões: Uma baixa prevalência de concentrações insuficientes de 25(OH)D foi observada. Não foram encontradas associações entre as concentrações séricas de 25(OH)D e PTH, FA, Ca, P e albumina. Da mesma forma, não foram encontradas associações entre de concentrações séricas de 25(OH)D, exposição solar e suplementação de VD. / Introduction: A high prevalence of vitamin D deficiency (VDD) in children has been observed worldwide, but there are few studies on the nutritional status of vitamin D (VD) in healthy infants. The main cause of deficiency in healthy children is breastfeeding without supplementation and lack or insufficiency of sun exposure. Objective: To determine serum concentrations of VD and verify its association with parathyroid hormone (PTH) levels and use of VD supplementation in healthy infants aged >= 6 to <= 24 months attended at two Basic Health Units in Ribeirão Preto city, São Paulo, Brazil. Methods: A cross-sectional, observational and analytical study was performed in which were determined serum concentrations of 25 (OH) D, PTH, alkaline phosphatase (AP), calcium (Ca), phosphorus (P) and albumin of 155 healthy infants. Information of sun exposure, sociodemographic aspects of mothers and clinical and nutritional characteristics of infants were obtained through interviews with responsible for infants. Serum concentrations of 25(OH)D greater than 20ng / ml were considered adequate, between 12 to 20ng / ml insufficient and <12ng/ml, deficient. Results: Ten infants (6.5%, 95% Confidence Interval 3.5-11.4) presented VD insufficiency and none presented DVD. Only one infant had an increase in PTH serum concentrations and 35.5% of infants had high AP but none presented DVD or VD insufficiency. No changes in serum P, Ca and albumin concentrations were detected. No associations were found between serum concentrations of 25 (OH) D and AP, Ca and albumin. There was an association between serum concentrations of 25(OH)D and PTH even after adjusting for sex, age and body mass index; an association between serum concentrations of 25(OH)D and P was observed only after adjustment for covariates. There were no associations between VD insufficiency, sun exposure and VD supplementation. Conclusions: A low prevalence of insufficient concentrations of 25 (OH)D was observed. No associations were found between serum concentrations of 25 (OH)D and PTH, FA, Ca, P and albumin. Likewise, no associations were found between serum concentrations of 25 (OH)D, sun exposure and VD supplementation.

Understanding the motives for sunbathing and indoor tanning is an extremely important public health issue. UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors for the development of skin cancer. Psychosocial models of UV exposure are often based on theories of health behavior, but theory from the body image field can be useful in understanding motives to UV expose as well. The current study examines models that prospectively predict sunbathing and indoor tanning behaviors using constructs and interrelationships derived from the tripartite theory of body image (Thompson et al., 1999), as well as those from the theory of reasoned action (Ajzen & Fishbein, 1980), health belief model (Rosenstock, 1974), revised protection motivation theory (Rogers, 1983), and a proposed integration of several health behavior models (Fishbein, 2000). The results generally support a model in which intentions mediate the relationship between appearance attitudes and tanning behaviors, appearance reasons to tan and intentions mediate the relationship between sociocultural influences and tanning behaviors, and appearance reasons not to tan and intentions mediate the role of perceived threat on behaviors. The implications of these findings yield important information relevant to the understanding of motives to UV expose, which can useful to the development of novel prevention and early intervention programs geared toward the reduction of skin cancer risk.

Understanding the motives for sunbathing and indoor tanning is an extremely important public health issue. Skin cancer rates have increased dramatically in recent years and UV exposure via sunbathing and utilization of sun lamps and tanning beds are considered important risk factors. Motives for sunbathing and tanning salon use have been thought to be related to appearance concerns, yet little research has examined the specific tan appearance attitudes that may contribute to use of these behaviors. Two studies were conducted with the aim of assessing distinct attitudes related to a tan appearance. In the first study items were created based on a review of the tanning literature and incorporation of constructs developed in the body image field, which were subsequently subject to exploratory factor analysis on 149 female university student sunbathers/tanning salon users.

Mass tourism being on the agenda of world tourism industry since post war period, has been facing stagnation with late 80&rsquo / s. Additionally consumer&rsquo / s preferences and tendencies towards seeking new activities regardless of sea-sun-sand type of tourism have been started to change. Therefore popular tourist destinations are in a position where to develop alternative tourist activities to sustain their market shares in world tourism market. In compliance with this trend, the purpose of this thesis is to analyze the need and the reason of Turkish Tourism Industry moving away from concentrating merely on mass tourism and accordingly to evaluate the efforts of Turkish tourism authorities in diversifying tourism activities and extending the tourist season to year round with reference to Tourism Development Regions, Amendment of Tourism Encouragement Law, etc. Additionally the importance of focusing on cultural, historical, traditional identity and unique assets of Turkey in order to sustain its ranking in the international tourism market is stressed.

Millions of Americans engage in tanning each year, defined as intentional ultraviolet radiation (UVR) exposure in the form of sunbathing or the use of indoor tanning beds. An emerging body of research suggests that UVR has addictive properties and some tanners engage in excessive tanning. This article provides an overview of the evidence of tanning addiction and a systematic review of existing tanning interventions with the goal of evaluating their potential to impact addicted tanners. Our search identified 24 intervention studies that were summarized and discussed according to 3 primary themes. First, there is a dearth of tanning interventions that target excessive tanning or are designed as treatments for tanning addiction. Second, tanning interventions are primarily educational interventions designed to increase knowledge of the risks of tanning. Third, there are notable aspects of existing tanning interventions that are relevant to addiction science, including the use of brief motivational and cognitive-behavioral-based interventions. Future directions are considered including recommendations for utilizing the existing evidence base to formulate interventions targeting excessive tanners.

This study explored the attitudes and behaviors of adolescents toward sunbathing and sunscreen use by employing the Theory of Alternative Behaviors (Jaccard, 1981) with adolescent participants and a respective parent co-participant. Females were found to be more likely to engage in intentional suntanning efforts, to stay in the sun for a longer duration, and to be more likely to use sunscreen yet to report higher incidence of sunburns. Those with a healthy lifestyle attitude are as likely to engage in intentional tanning, although they are more likely to wear sunscreen. Self-report of tanning behavior was positively correlated to parent's observation of adolescent's behavior. Results of this study support the position that sunscreen partially allows for longer sunlight exposure resulting in higher amounts of UV radiation exposure. Participants who were more likely to wear sunscreen were likewise more likely to spend more time in the sun and to sunburn more frequently.

BACKGROUND: A social media campaign for mothers aimed at reducing indoor tanning (IT) by adolescent daughters reduced mothers' permissiveness toward IT in an immediate posttest. Whether the effects persisted at 6 months after the campaign remains to be determined. METHODS: Mothers (N = 869) of daughters ages 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial. All mothers received an adolescent health campaign over 12 months with posts on preventing IT (intervention) or prescription drug misuse (control). Mothers completed a follow-up at 18 months post-randomization measuring IT permissiveness, attitudes, intentions, communication, and behavior, and support for state bans. Daughters (n = 469; 54.0%) just completed baseline and follow-up surveys. RESULTS: Structural equation modeling showed that intervention-group mothers were less permissive of IT by daughters [unstandardized coefficient, -0.17; 95% confidence interval (CI), -0.31 to -0.03], had greater self-efficacy to refuse daughter's IT requests (0.17; 95% CI, 0.06-0.29) and lower IT intentions themselves (-0.18; 95% CI, -0.35 to -0.01), and were more supportive of bans on IT by minors (0.23; 95% CI, 0.02-0.43) than control-group mothers. Intervention-group daughters expressed less positive IT attitudes than controls (-0.16; 95% CI, 0.31 to -0.01). CONCLUSIONS: The social media campaign may have had a persisting effect of convincing mothers to withhold permission for daughters to indoor tan for 6 months after its conclusion. Reduced IT intentions and increased support for bans on IT by minors also persisted among mothers. IMPACT: Social media may increase support among mothers to place more restrictions on IT by minors.
