Understanding Community-based HIV/AIDS Service Organizations: An Invaluable Source of HPV-related Cancer Information for At-risk Populations.

To describe non-clinical HIV service providers (NCHSPs) as surrogate seekers and health information mavens for people living with HIV (PLWH), men who have sex with men (MSM), and other vulnerable populations.In May/June 2016, we recruited 30 NCHSPs from three community-based HIV/AIDS service organizations. NCHSPs completed a 118-item self-administered, paper-and-pencil survey about HPV, cancer, and health communication. Data were analyzed using Stata/SE 14.1.Almost all (97%) NCHSPs were surrogate seekers and had looked for HIV/AIDS (97%), STD (97%), and cancer (93%) information. Most (60%) cancer information seekers had looked for information about HPV. The Internet (97%) and healthcare providers (97%) were health information sources almost all NCHSPs trusted. Nearly all NCHSPs (93%) were completely or very confident about their ability to find health information. The mean health information mavenism score (17.4 ± 2.1) was significantly higher than the scale's high-score cutoff (15.0) (p < 0 .001).NCHSPs look for and share health information with the vulnerable populations (e.g., PLWH, MSM) they serve. More research is needed to understand what NCHSPs' know and think about the health information they are sharing with vulnerable populations.

Social network analysis for assessing college-aged adults' health: A systematic review.

OBJECTIVE: Social network analysis (SNA) is a useful, emerging method for studying health. College students are especially prone to social influence when it comes to health. This review aimed to identify network variables related to college student health and determine how SNA was used in the literature. PARTICIPANTS: A systematic review of relevant literature was conducted in October 2015. METHODS: Studies employing egocentric or whole network analysis to study college student health were included. We used Garrard's Matrix Method to extract data from reviewed articles (n = 15). RESULTS: Drinking, smoking, aggression, homesickness, and stress were predicted by network variables in the reviewed literature. Methodological inconsistencies concerning boundary specification, data collection, nomination limits, and statistical analyses were revealed across studies. CONCLUSIONS: Results show the consistent relationship between network variables and college health outcomes, justifying further use of SNA to research college health. Suggestions and considerations for future use of SNA are provided.

Predictors of Intention to Obtain Colorectal Cancer Screening Among African American Men in a State Fair Setting.

Racial disparities in health among African American men in the United States are appalling. African American men have the highest mortality and incidence rates from colorectal cancer compared with all other ethnic, racial, and gender groups. Juxtaposed to their white counterparts, African American men have colorectal cancer incidence and mortality rates 27% and 52% higher, respectively. Colorectal cancer is a treatable and preventable condition when detected early, yet the intricate factors influencing African American men's intention to screen remain understudied. Employing a nonexperimental, online survey research design at the Minnesota State Fair, the purpose of this study was to explore whether male role norms, knowledge, attitudes, and perceptions influence intention to screen for colorectal cancer among 297 African American men. As hypothesized, these Minnesota men (ages 18 to 65) lacked appropriate colorectal cancer knowledge: only 33% of the sample received a "passing" knowledge score (85% or better). In a logistic regression model, the three factors significantly associated with a higher probability of obtaining colorectal cancer screening were age, perceived barriers, and perceived subjective norms. Findings from this study provide a solid basis for informing health policy and designing health promotion and early-intervention colorectal cancer prevention programs that are responsive to the needs of African American men in Minnesota and beyond.

Measuring Factors Associated with Colorectal Cancer Screening among Young Adult African American Men: A Psychometric Study.

The Male Role Norms, Knowledge, Attitudes, and Perceptions associated with Colorectal Cancer Screening (MKAP-CRCS) survey was developed to assess the attitudes, knowledge, male role norms, perceived barriers, and perceived subjective norms associated with screening for colorectal cancer (CRC) among young adult African American men. There is a critical need for exploring the complex factors that may shape attitudes towards CRC screening among men who are younger (i.e., ages 19-45) than those traditionally assessed by clinicians and health promotion researchers (age 50 and older). Psychometrically sound measures are crucial for eliciting valid and reliable data on these factors. The current study, therefore, assessed the psychometric properties of the MKAP-CRCS instrument using an online sample of young adult African American men (N = 157) across the United States. Exploratory principal component factor analyses revealed that the MKAP-CRCS measure yielded construct valid and reliable scores, suggesting that the scale holds promise as an appropriate tool for assessing factors associated with CRC screening among younger African American men. Strengths and limitations of this study, along with directions for future research are discussed, including the need for more research examining the relationship between masculinity and CRC screening among African American men.

Explanatory Models of Genetics and Genetic Risk among a Selected Group of Students.

This exploratory qualitative study focuses on how college students conceptualize genetics and genetic risk, concepts essential for genetic literacy (GL) and genetic numeracy (GN), components of overall health literacy (HL). HL is dependent on both the background knowledge and culture of a patient, and lower HL is linked to increased morbidity and mortality for a number of chronic health conditions (e.g., diabetes and cancer). A purposive sample of 86 students from three Southwestern universities participated in eight focus groups. The sample ranged in age from 18 to 54 years, and comprised primarily of female (67.4%), single (74.4%), and non-White (57%) participants, none of whom were genetics/biology majors. A holistic-content approach revealed broad categories concerning participants' explanatory models (EMs) of genetics and genetic risk. Participants' EMs were grounded in highly contextualized narratives that only partially overlapped with biomedical models. While higher education levels should be associated with predominately knowledge-based EM of genetic risk, this study shows that even in well-educated populations cultural factors can dominate. Study findings reveal gaps in how this sample of young adults obtains, processes, and understands genetic/genomic concepts. Future studies should assess how individuals with low GL and GN obtain and process genetics and genetic risk information and incorporate this information into health decision making. Future work should also address the interaction of communication between health educators, providers, and genetic counselors, to increase patient understanding of genetic risk.

The Role of Gender in Adolescents' Social Networks and Alcohol, Tobacco, and Drug Use: A Systematic Review.

BACKGROUND: Despite previous research indicating an adolescents' alcohol, tobacco, and other drug (ATOD) use is dependent upon their sex and the sex composition of their social network, few social network studies consider sex differences and network sex composition as a determinant of adolescents' ATOD use behavior. METHODS: This systematic literature review examining how social network analytic studies examine adolescent ATOD use behavior is guided by the following research questions: (1) How do studies conceptualize sex and network sex composition? (2) What types of network affiliations are employed to characterize adolescent networks? (3) What is the methodological quality of included studies? After searching several electronic databases (PsycINFO, EBSCO, and Communication Abstract) and applying our inclusion/exclusion criteria, 48 studies were included in the review. RESULTS: Overall, few studies considered sex composition of networks in which adolescents are embedded as a determinant that influences adolescent ATOD use. Although included studies all exhibited high methodological quality, the majority only used friendship networks to characterize adolescent social networks and subsequently failed to capture the influence of other network types, such as romantic networks. CONCLUSIONS: School-based prevention programs could be strengthened by (1) selecting and targeting peer leaders based on sex, and (2) leveraging other types of social networks beyond simply friendships.

What's love got to do with it? Adolescent romantic networks and substance use.

This study examined how romantic aspiration network characteristics at the individual level (in-degree and out-degree) are associated with substance use (i.e. smoking and drinking) among a cross-sectional sample of US adolescents (10th grade, n = 1523) from 4 high schools in Los Angeles. Findings highlighted that, with an increase in out-degree (romantic aspiration nominations made), adolescents in our sample were less likely (OR = .824, CI = .688-.986, p < .05) to report smoking in the past 30 days. Additionally, with an increase in in-degree (romantic aspiration nominations received), adolescents were more likely (OR = 1.186, CI = 1.04-1.36, p < .05) to report drinking in the past 30 days. We conclude that romantic aspirations/relations influence adolescents' substance use behaviour (i.e. smoking and drinking alcohol), particularly because of the intensity of such relationships and the desire to please or be acceptable to the other person. Moreover, understanding adolescents' aspirations/relations can be useful for the development of intervention/prevention programmes to target adolescents' substance use.

Factors Associated with Colorectal Cancer Screening among Younger African American Men: A Systematic Review.

Of cancers affecting both men and women, colorectal cancer (CRC) is the second leading cancer killer among African Americans in the U.S. Compared to White men, African American men have incidence and mortality rates 25% and 50% higher from CRC. Despite the benefits of early detection and the availability of effective screening, most adults over age 50 have not undergone testing, and disparities in colorectal cancer screening (CRCS) persist. Owing to CRC's high incidence and younger age at presentation among African American men, CRCS is warranted at age 45 rather than 50. However, the factors influencing young adult (i.e., age < 50) African American men's intention to screen and/or their CRCS behaviors has not been systematically assessed. To assess whether the factors influencing young adult African American men's screening intentions and behaviors are changeable through structured health education interventions, we conducted a systematic review, with the two-fold purpose of: (1) synthesizing studies examining African American men's knowledge, beliefs, and behaviors regarding CRCS; and (2) assessing these studies' methodological quality. Utilizing Garrard's Matrix Method, a total of 28 manuscripts met our inclusion/exclusion criteria: 20 studies followed a non-experimental research design, 4 comprised a quasi-experimental design, and 4, an experimental design. Studies were published between 2002 and 2012; the majority, between 2007 and 2011. The factors most frequently assessed were behaviors (79%), beliefs (68%), and knowledge (61%) of CRC and CRCS. Six factors associated with CRC and CRCS emerged: previous CRCS, CRC test preference, perceived benefits, perceived barriers, CRC/CRCS knowledge, and physician support/recommendation. Studies were assigned a methodological quality score (MQS - ranging from 0 to 21). The mean MQS of 10.9 indicated these studies were, overall, of medium quality and suffered from specific flaws. Alongside a call for more rigorous research, this review provides important suggestions for practice and culturally relevant interventions.

US adolescents' friendship networks and health risk behaviors: a systematic review of studies using social network analysis and Add Health data.

Background. Documented trends in health-related risk behaviors among US adolescents have remained high over time. Studies indicate relationships among mutual friends are a major influence on adolescents' risky behaviors. Social Network Analysis (SNA) can help understand friendship ties affecting individual adolescents' engagement in these behaviors. Moreover, a systematic literature review can synthesize findings from a range of studies using SNA, as well as assess these studies' methodological quality. Review findings also can help health educators and promoters develop more effective programs. Objective. This review systematically examined studies of the influence of friendship networks on adolescents' risk behaviors, which utilized SNA and the Add Health data (a nationally representative sample). Methods. We employed the Matrix Method to synthesize and evaluate 15 published studies that met our inclusion and exclusion criteria, retrieved from the Add Health website and 3 major databases (Medline, Eric, and PsycINFO). Moreover, we assigned each study a methodological quality score (MQS). Results. In all studies, friendship networks among adolescents promoted their risky behaviors, including drinking alcohol, smoking, sexual intercourse, and marijuana use. The average MQS was 4.6, an indicator of methodological rigor (scale: 1-9). Conclusion. Better understanding of risky behaviors influenced by friends can be useful for health educators and promoters, as programs targeting friendships might be more effective. Additionally, the overall MQ of these reviewed studies was good, as average scores fell above the scale's mid-point.

School nurses' knowledge, attitudes, perceptions of role as opinion leader, and professional practice regarding human papillomavirus vaccine for youth.

BACKGROUND: Because human papillomavirus (HPV) vaccine rates remain low, we evaluated US school nurses' knowledge, attitudes, perceptions of their role as opinion leaders, and professional practice regarding HPV vaccine, and assessed whether knowledge, attitudes, and perceptions of being an opinion leader influenced their professional practice regarding the HPV vaccine. METHODS: We used a cross-sectional design by recruiting members from the National Association of School Nurses. All participants (N = 505) were e-mailed a survey designed for this study. Structural equation modeling (SEM) tested direct and indirect effects. RESULTS: Overall, school nurses had knowledge about HPV and the vaccine, and positive attitudes toward the vaccine. They had less-than-enthusiastic perceptions of their role as opinion leaders regarding the vaccine and implemented few activities related to providing vaccine information. The model revealed a good fit (χ(2)=20.238 [df=8, p< .01]), with knowledge directly related to attitudes, attitudes directly related to perceptions and practice, and perceptions directly affecting practice. In our model, perceptions functioned as a partial mediator. CONCLUSIONS: To enhance school nurses' practice regarding the HPV vaccine, focus should be on increasing positive attitudes toward the vaccine and strengthening perceptions of their role as opinion leaders.

Male Role Norms, Knowledge, Attitudes, and Perceptions of Colorectal Cancer Screening among Young Adult African American Men.

Racial disparities in health among African American men (AAM) in the United States are extensive. In contrast to their White counterparts, AAM have more illnesses and die younger. AAM have colorectal cancer (CRC) incidence and mortality rates 25% and 50% higher, respectively, than White men. Due to CRC's younger age at presentation and high incidence among AAM, CRC screening (CRCS) is warranted at the age of 45 rather than 50, but little is known about younger AAM's views of CRCS. Employing survey design, the purpose of the study was to describe the male role norms (MRN), knowledge, attitudes, perceived subjective norms, and perceived barriers associated with screening for CRC among a non-random sample of 157 young adult AAM (ages 19-45). Sixty-seven percent of the study sample received a passing knowledge score (85% or better), yet no significant differences were found among the three educational levels (i.e., low, medium, high). More negative attitudes toward CRCS correlated with the participants' strong perceptions of barriers, but no extremely negative or positive MRN and perceived subjective norms were found. The factors significantly associated with attitudes were family history of cancer (unsure), work status, and perceived barriers. Findings from this study provide a solid basis for developing structured health education interventions that address the salient factors shaping young adult AAM's view of CRC and early detection screening behaviors.

Perceived barriers to children's active commuting to school: a systematic review of empirical, methodological and theoretical evidence.

Active commuting to school (ACS) may increase children's daily physical activity and help them maintain a healthy weight. Previous studies have identified various perceived barriers related to children's ACS. However, it is not clear whether and how these studies were methodologically sound and theoretically grounded. The purpose of this review was to critically assess the current literature on perceived barriers to children's ACS and provide recommendations for future studies. Empirically based literature on perceived barriers to ACS was systematically searched from six databases. A methodological quality scale (MQS) and a theory utilization quality scale (TQS) were created based on previously established instruments and tailored for the current review. Among the 39 studies that met the inclusion criteria, 19 (48.7%) reported statistically significant perceived barriers to child's ACS. The methodological and theory utilization qualities of reviewed studies varied, with MQS scores ranging between 7 and 20 (Mean =12.95, SD =2.95) and TQS scores from 1 to 7 (Mean =3.62, SD =1.74). A detailed appraisal of the literature suggests several empirical, methodological, and theoretical recommendations for future studies on perceived barriers to ACS. Empirically, increasing the diversity of study regions and samples should be a high priority, particularly in Asian and European countries, and among rural residents; more prospective and interventions studies are needed to determine the causal mechanism liking the perceived factors and ACS; future researchers should include policy-related barriers into their inquiries. Methodologically, the conceptualization of ACS should be standardized or at least well rationalized in future studies to ensure the comparability of results; researchers' awareness need to be increased for improving the methodological rigor of studies, especially in regard to appropriate statistical analysis techniques, control variable estimation, multicollinearity testing, and reliability and validity reporting. Theoretically, future researchers need to first ground their investigations in theoretical foundations; efforts should be devoted to make sure theories are used thoroughly and correctly; important theoretical constructs, in particular, need to be conceptualized and operationalized appropriately to ensure accurate measurement. By reviewing what has been achieved, this review offered insights for more sophisticated ACS studies in the future.

A recommendation to use the diffusion of innovations theory to understand school nurses' role in HPV vaccine uptake.

Vaccinations represent one of the greatest public health achievements of the past century, but their success largely depends on populations' uptake. Seven years after its approval in 2006 for females, the HPV vaccination rates remain relatively low. Previous literature provides information about research examining U.S. physicians, pediatricians, and other healthcare providers' knowledge, attitudes, and professional practice toward the HPV vaccine. No research has yet investigated U.S. school nurses' role in educating the school community about the vaccine's benefits. Diffusion of Innovations theory is an appropriate perspective for examining school nurses as opinion leaders who can influence the uptake of the HPV vaccine for youth. This theory explains how innovations diffuse throughout a social system, and highlights the construct of opinion leadership. School nurses exhibit the characteristics of opinion leaders; therefore, Diffusion of Innovations can be a useful lens for assessing their role in efforts to promote HPV vaccination for youth.

Factors affecting decisions to accept or decline cystic fibrosis carrier testing/screening: a theory-guided systematic review.

PURPOSE: To assess factors affecting individuals' decision to accept or decline cystic fibrosis carrier testing/screening, as reported in studies published until December 2006. The Health Belief Model guided classification of each factor, and the studies' methodological quality was assessed. METHODS: A three-stage search and retrieval process, alongside application of specific inclusion/exclusion criteria, yielded 40 studies (in 35 articles). For each reviewed study, authors abstracted and organized selected data into a matrix and assigned a methodological quality score. RESULTS: The four most frequently identified acceptance factors included three Health Belief Model factors and one non-Health Belief Model factor: perceived benefits of undergoing cystic fibrosis carrier testing/screening, weaker perception of barriers to cystic fibrosis carrier testing/screening, fewer/no children or desiring children, and research-related factors (non-Health Belief Model factor construct). All four most frequent factors associated with declining testing were Health Belief Model factor constructs: perceived barriers to obtaining cystic fibrosis carrier testing/screening, parity, lack of knowledge, and weaker perception of benefits of undergoing cystic fibrosis carrier testing/screening. The average methodological quality of the studies was 10.2 (SD=3.2; range, 5-18 points). CONCLUSIONS: The methodological and theoretical quality of this body of literature could be substantially improved if researchers employed theory-based approaches, tested (and reported) the validity/reliability of their own data, and employed multivariate statistical analyses and/or better controlled research designs. Improving the quality of future studies may allow better inferences regarding the relative contribution of each factor identified in this review to individuals' decision-making process.

O risco de contaminaçäo com vírus da AIDS e percepçäo desse risco entre estudantes da UNICAMP / The risk of contamination with the AIDS virus and perception of that risk among students of UNICAMP

Analisaram-se 736 questionários que indagaram sobre conhecimentos relativos ao contágio pelo vírus da AIDS, enviados a alunos aprovados no vestibular da UNICAMP em 1986 e 1987. Quase todos (98,5% e 99,8%) dos 736 estudantes que responderam, sabiam que a transmissäo do vírus näo é só entre homossexuais, que o condon reduz o risco e que a infecçäo também pode ser adquirida através de transfusöes de sangue e uso de agulhas näo esterilizadas. Mais de 85% sabiam que a principal via de transmissäo é a sexual. Uma porcentagem menor (54,4%) sabiam que o risco de infecçäo da relaçäo anal é maior que o de outras atividades sexuais. Segundo as respostas que avaliavam comportamentos de riscos, cada estudante foi classificado como de risco alto, baixo ou nulo de contrair AIDS. Essa classificaçäo foi comparada com a autoavaliaçäo que cada estudante fez do seu risco, também classificado como alto, baixo ou nulo. A porcentagem em que os estudantes se autoavaliaram nas diferentes categorias näo foi significantemente diferente nos de alto risco real comparados com os de risco real nulo. Os autores concluem que as atividades educacionais em relaçäo a AIDS devem visar a conscientizaçäo e mudanças de atitudes e näo apenas limitar-se a dar informaçöes (AUs

O sistema anticonceptivo Norplant do ponto de vista das usuárias / The Norplant contraceptive system of users point of view

O objetivo da pesquisa foi conhecer a experiência e a opiniäo de um grupo de mulheres brasileiras que aceitaram experimentar o sistema anticoncepcional Norplant. Foram estudadas 280 mulheres, selecionadas em três clínicas de planejamento familiar em Campinas, Curitiba e Fortaleza. Houve poucas diferenças significativas entre as clínicas. A equimose foi a moléstia mais freqüentemente relacionada com a inserçäo (60%), e a coceira foi o sintoma local mais comumente mencionado (40%) durante o uso. A percentagem de mulheres que disseram que as cólicas menstruais, corrimento, dor de cabeça e nervosismo tinham diminuido com o uso do método foi maior do que a das que relataram aumento. Mais da metade das mulheres estudadas estiveram em amenorréia durante dois ou mais meses, ou menstruaram, sangraram e/ou mancharam durante dez ou mais dias em um mês. A grande maioria das usuárias (77,2%) considerou "boa ou "muito boa" sua experiência com o Norplant e 80,6% disse tê-lo recomendado a outra mulher

Percepçäo das usuárias de Norplant a respeito da informaçäo recebida sobre o método / Perception of Norplant users concerning information received about the method

Esse trabalho apresenta resultados de um estudo desenvolvido em 1985 com 280 usuários dos implantes contraceptivos subdérmicos Norplant em três cidades brasileiras (Curitiba, Fortaleza e Campinas). As mulheres foram entrevistadas em seus domicílios através de um questionário estruturado pré-testado. Além de se estudarem características das usuárias, sua percepçäo da informaçäo recebida e sua satisfaçäo com o método, objetivou-se verificar até que ponto a informaçäo recebida nas clínicas de planejamento familiar tenha sido retida pelas mulheres, e o que lembravam dessa informaçäo vários meses após o início do uso do método. Como já se esperava, encontravam-se diferenças significativas entre os grupos de cada clínica estudada. Duas das clínicas informavam adequadamente suas clientes enquanto a terceira mostrou sérias deficiências na transmissäo de informaçöes indispensáveis para o uso apropriado do Norplant. Além disso, aparentemente, nem todas as mulheres que aceitaram o método nessa última clínica tinham compreendido plenamente que se tratava de um método em processo de pesquisa
