A Randomized Controlled Trial of an Appearance-Focused Intervention to Prevent Skin Cancer

Hillhouse, Joel, Turrisi, Rob, Stapleton, Jerod, Robinson, June 01 December 2008 (has links)
BACKGROUND. Skin cancer represents a significant health threat with over 1.3 million diagnoses, 8000 melanoma deaths, and more than $1 billion spent annually for skin cancer healthcare in the US. Despite findings from laboratory, case-control, and prospective studies that indicate a link between youthful indoor tanning (IT) and skin cancer, IT is increasing among US youth. Appearance-focused interventions represent a promising method to counteract these trends. METHODS. A total of 430 female indoor tanners were randomized into intervention or no intervention control conditions. Intervention participants received an appearance-focused booklet based on decision-theoretical models of health behavior. Outcome variables included self-reports of IT behavior and intentions, as well as measures of cognitive mediating variables. RESULTS. Normative increases in springtime IT rates were significantly lower (ie, over 35%) at 6-month follow-up in intervention versus control participants with similar reductions in future intentions. Mediation analyses revealed 6 cognitive variables (IT attitudes, fashion attitudes, perceived susceptibility to skin cancer and skin damage, subjective norms, and image norms) that significantly mediated change in IT behavior. CONCLUSIONS. The appearance-focused intervention demonstrated strong effects on IT behavior and intentions in young indoor tanners. Appearance-focused approaches to skin cancer prevention need to present alternative behaviors as well as alter IT attitudes. Mediational results provide guides for strengthening future appearance-focused interventions directed at behaviors that increase risk of skin cancer.

Self-Reported Substance Use and Sexual Behaviors Among Adolescents in a Rural State

Dunn, Michael, Ilapogu, Varaprasad, Taylor, Lashan, Naney, C., Blackwell, Roger, Wilder, Regina, Givens, C. 01 November 2008 (has links)
Background: Research finds a strong association between substance use and risky sexual behavior but more needs to be known about this relationship. Few studies have examined this relationship among rural sixth- to eighth-grade students. As such, the purposes of this study were to provide a descriptive profile of rural sixth- to eighth-grade students' substance use behavior and sexual activity and to examine the relationship between substance use behaviors and sexual activity. Methods Participants consisted of a convenience sample of 10,273 middle school students (sixth to eighth grade) attending 10 public schools in rural Tennessee. The middle school Youth Risk Behavior Survey was administered to these students during April and May 2004. Results Analysis found that a large percentage of students had tried cigarettes, alcohol, and inhalants. Additionally, it was found that sexual intercourse had been initiated by 18.8% of females and 25.4% of males. Of those students who reported ever having had sexual intercourse, 75% had reported the use of cigarettes and alcohol. In addition, approximately 50% of those students reported marijuana and inhalant use. Conclusions The results suggest that substance use behavior has a relationship with the likelihood of initiating sexual activity. Additional longitudinal research with this population will be needed for explaining whether these select substance use behaviors are probable risk factors predisposing young rural adolescents to report engaging in sexual behaviors or a result of other factors.

Examination of the Efficacy of An Appearance-Focused Intervention to Reduce UV Exposure

Hillhouse, Joel J., Turrisi, Rob 01 August 2002 (has links)
This study designed and implemented an appearance-based skin cancer prevention intervention in college-aged females. One hundred and forty-seven respondents were randomly assigned to treatment or control groups. Treatment respondents received a short workbook describing the appearance damaging effects of indoor tanning. At short-term follow-up (2 weeks later) treatment respondents had significantly more negative attitudes toward indoor tanning, and reported fewer intentions to indoor tan. At 2-month follow-up, treatment respondents reported indoor tanning one-half as much as control respondents in the previous 2 months. This appearance-based intervention was able to produce clinically significant changes in indoor tanning use tendencies that could have a beneficial effect on the future development of skin cancer.

Social Support for Physical Activity for High Schoolers in Rural Southern Appalachia

Shah, Pooja, Southerland, Jodi L., Slawson, Deborah L. 01 December 2019 (has links)
Objective: Social support for physical activity (PA) has been shown to enhance PA levels in adolescents. Although social support has been examined extensively in the literature, less is known about the role of social support for PA for high school adolescents in rural southern Appalachia. PA is important because adolescent obesity is greater in Appalachia than in the rest of the United States. Methods: This was a qualitative secondary analysis of focus groups conducted in 2013-2014 among parents, teachers, and high school students (N = 77) in 6 counties across rural southern Appalachia. Beets' typology of social support was used to categorize themes. Results: Participants discussed instrumental supports, including providing transportation and paying fees, enrolling child in recreation/sports, and providing PA equipment at home. Performing PA with adolescents and modeling, watching/supervising, and prioritizing PA were identified as conditional supports. Several motivational supports were identified: encouragement, force, and the admiration of people who are active. Participants also identified key informational supports, including discussing the importance/health benefits of PA, how to be physically active, and general advice/information. Barriers to PA engagement (eg, body image issues, bullying, competitive nature of PA opportunities) and the role of referent groups (eg, family, peers, teachers) emerged as important concepts in the discussion. Conclusion This study identifies opportunities and practical ways for families and schools to provide, build, and strengthen supports for PA among adolescents in rural Appalachia.

Content Analysis of Twitter Chatter About Indoor Tanning

Waring, Molly E., Baker, Katie, Peluso, Anthony, May, Christine N., Pagoto, Sherry L. 01 January 2019 (has links)
Twitter may be useful for learning about indoor tanning behavior and attitudes. The objective of this study was to analyze the content of tweets about indoor tanning to determine the extent to which tweets are posted by people who tan, and to characterize the topics of tweets. We extracted 4,691 unique tweets from Twitter using the terms “tanning bed” or “tanning salon” over 7 days in March 2016. We content analyzed a random selection of 1,000 tweets, double-coding 20% of tweets (κ = 0.74, 81% agreement). Most tweets (71%) were by tanners (n = 699 individuals) and included tweets expressing positive sentiment about tanning (57%), and reports of a negative tanning experience (17%), burning (15%), or sleeping in a tanning bed (9%). Four percent of tweets were by tanning salon employees. Tweets posted by people unlikely to be tanners (15%) included tweets mocking tanners (71%) and health warnings (29%). The term “tanning bed” had higher precision for identifying individuals who engage in indoor tanning than “tanning salon”; 77% versus 45% of tweets captured by these search terms were by individuals who engaged in indoor tanning, respectively. Extrapolating to the full data set of 4,691 tweets, findings suggest that an average of 468 individuals who engage in indoor tanning can be identified by their tweets per day. The majority of tweets were from tanners and included reports of especially risky habits (e.g., burning, falling asleep). Twitter provides opportunity to identify indoor tanners and examine conversations about indoor tanning.

A Cross-Sectional Study of the Association Between Perfluorinated Chemical Exposure and Cancers Related to Deregulation of Estrogen Receptors

Omoike, Ogbebor Enaholo, Pack, Robert P., Mamudu, Hadii M., Liu, Ying, Wang, Liang 01 January 2020 (has links)
Background: Environmental exposures acting through different mechanisms have been linked with a number of cancers. Perfluoroalkyl chemicals (PFCs) are endocrine disrupting chemicals affecting estrogen homeostasis. Objectives: We examined the association between PFCs and a group of estrogen related cancers and explored if increased non-occupational exposure was associated with increased odds of developing these cancers. We also explored which of these chemical exposures was more correlated with each cancer. Methods: Using data from the National Health and Nutrition Examination Survey (NHANES), we selected participants ≥ 20 years of age. Our outcome variable was presence or absence of breast, prostate, ovarian and uterine cancer (yes/no); our exposure variables were serum PFCs. Logistic regression models were used in investigating the association between PFCs and cancer types and between quartiles of PFCs exposure concentrations and presence or absence of cancer while adjusting for covariates. Discriminant analysis was used to assess the correlation between individual PFCs compounds and individual cancer types. Results: PFCs were associated with increased odds of ovarian cancer; PFOA: 1.02(1.01, 1.02), PFOS: 1.01 (1.012, 1.013), PFHS 1.031 (1.030, 1.033), PFDE: 1.29(1.27, 1.30) and increased odds of breast cancer; PFOA: 1.089(1.089, 1.09), PFOS: 1.011(1.011, 1.011), PFNA: 1.031(1.030, 1.033), PFHS: 1.02 (1.02, 1.02), PFDE: 1.19(1.18, 1.19). PFCs were not associated with increased odds of prostate or uterine cancers. Comparing the odds in quartile 4 to quartile 1 for ovarian cancer, PFOA: 1.77(1.75,1.79), PFOS: 2.25(2.22, 2.28), PFHS: 1.86(1.84, 1.88), PFDE: 2.11(2.09, 2.14). For breast cancer, PFOA: 2.30(2.28, 2.31), PFOS: 1.47(1.46, 1.48), PFNA: 1.04(1.03, 1.05), PFHS:7.07(6.97,7.17), PFDE: 1.38(1.37, 1.39). PFOA was more correlated with breast cancer (0.7) and PFHS was more correlated with ovarian cancer (0.9). Discussion: PFCs were associated with increased odds of ovarian and breast cancers with a positive dose-response relationship. PFOA was more correlated with breast cancer and PFHS more with ovarian cancer.

Perceptions of Interprofessional Education Through the Eyes of Students: A Thematic Analysis

Freeland, Catherine A., Baker, Katie, Dean, Rachel, Masters, Jordan, Patel, Hiral, Polaha, Jodi, Bishop, Tom 01 January 2015 (has links)
Discussion surrounding interprofessional education (IPE) among graduate and professional health sciences students is beginning to appear more frequently in academic journals, government reports, and health care reform recommendations. Recommendations from an international conference cited in the Lancet provide an interesting overview from world leaders about interprofessional care and its ability to improve health system performance. Since 1995, the Academic Health Sciences Center (AHSC) at East Tennessee State University (ETSU) has shown the value of IPE and continues to do so through the Interprofessional Education Program (IPEP). In this study, a focus group was conducted in fall 2014 to collect qualitative data on AHSC students’ perceptions of IPE and interprofessional training at ETSU. Two out of five AHSC colleges were represented by a total of four focus group participants. These participants included students from the Colleges of Public Health and Medicine, as well as a student from the Department of Psychology and one medical resident. Through use of a semi-structured interview procedure, a skilled facilitator asked participants to describe their academic experiences related to IPE at ETSU. A series of open-ended questions were presented in order to determine the general perceptions, attitudes, barriers, and beliefs of health science students regarding interprofessional experiences. The focus group was audio- and video- recorded, and the recordings were transcribed by the author. Four study staff members met and conducted separate thematic analyses to determine consensus on overarching themes from transcriptions. Themes identified through these analyses included: 1) specific emphasis on the importance of communication; 2) respect for the academic rigor of other health profession programs; 3) the desire for more IPE opportunities; and 4) having a positive and open mind was a characteristic considered impactful interprofessional education. The implications of these findings and considerations for methodological improvements will be discussed.

A Qualitative Research Synthesis of Contextual Factors Contributing to Female Overweight and Obesity over the Life Course in Sub-Saharan Africa

Ozodiegwu, Ifeoma, Littleton, Mary Ann, Nwabueze, Christian, Famojuro, Oluwaseun, Quinn, Megan, Wallace, Rick L., Mamudu, Hadii M. 01 January 2019 (has links) (PDF)
Objective: Adult women are disproportionately affected by overweight and obesity in Sub-Saharan African (SSA) countries. Existing evidence on the sociocultural context remains unconsolidated. In this qualitative research synthesis, we aggregate research literature on contextual factors that potentially predispose adult women and adolescent girls to overweight and obesity to inform research, policies and programs over the life course. Methods: PubMed, CINAHL, PsychInfo, ProQuest Central, EMBASE, and Web of Science were searched to locate qualitative research articles conducted in SSA countries beginning in the year 2000. After assessment for eligibility and critical appraisal, 17 studies were included in the synthesis. Textual data and quotes were synthesized using meta-aggregation methods proposed by the Joanna Briggs Institute. Results: The synthesized studies were conducted in South Africa, Ghana, Kenya and Botswana. The three overarching themes across these studies were body size and shape ideals, barriers to healthy eating, and barriers to physical activity, with cultural and social factors as cross-cutting influences within the major themes. Culturally, the supposedly ideal African woman was expected to be overweight or obese, and voluptuous, and this was associated with their identity. Although being overweight or obese was not acceptable to adolescent girls, they desired to be voluptuous. Healthy food choices among women and adolescent girls were hampered by several factors including affordability of nutritious foods and peer victimization. Both adult women and adolescent girls experienced ageism as a barrier to physical activity. Significance: This is the first qualitative research synthesis to amplify the voices of women and girls in SSA countries highlighting the challenges they face in maintaining a healthy body weight. Sociocultural, institutional and peer-related factors were powerful forces shaping body size preferences, food choices and participation in physical activity. Our study findings provide insights for the design of contextually appropriate obesity prevention interventions and lay the foundation for further research studies.

Maximizing Public Benefit From Opioid Settlement Resources

Pack, Robert P., Healton, Cheryl G., Galea, Sandro 01 March 2020 (has links)
The historic tobacco Master Settlement Agreement (MSA) between 46 State Attorneys General and the tobacco industry in 1999 had a range of consequences. It resulted in the closure of tobacco industry policy groups that undermined public health, sharply reduced tobacco marketing using cartoon characters (eg, Joe Camel) and paid product placement in television, film and other media, and created a new nonprofit foundation whose primary goal was to educate youth and prevent them from initiating tobacco use. It also resulted in more than $206 billion in resources being allocated to states, subject to appropriation by state legislators and governors. This enabled states to recoup the cost of medical and other treatment expenditures for tobacco‐related illness.1 However, by 2018, only 2.6% of the $206 billion in settlement and tobacco state taxes had been used for tobacco‐related harm mitigation or prevention.
