<p> The purpose of this study was to assess changes in after-school time spent performing sedentary behavior (SB), light intensity physical activity (LPA), and moderate to vigorous-intensity physical activity (MVPA) among elementary school children in response to the introduction of stand-biased desks in the classroom. Thirty-one 6^th grade participants randomly assigned by their teacher to a traditional (CON) or stand-biased (INT) desk provided complete accelerometer data. After-school PA and SB were measured on four consecutive weekdays at baseline and 10-weeks. Wilcoxon Rank Sum Tests were used to detect significant differences (p&lt;0.10) in changes in the proportion of after-school wear time performing SB and PA between groups. Results suggested no significant differences in changes in after-school time performing SB (p=0.770), LPA (p=0.740), or MVPA (p=0.470). Significant differences in the change in moderate PA (INT: -1.4%; CON: -0.2%, p=0.093) were detected. Stand-biased desks were not detrimental to children&rsquo;s after-school PA and SB.</p><p>

<p> Waiters who serve alcoholic beverages at the majority of bars and restaurants in the United States are apt to serve alcohol to patrons who are visually intoxicated, notwithstanding laws prohibiting such service. Adverse effects of this practice include patron injuries, deaths, and law violations resulting in fines, incarceration, and lawsuits. Waiters not effectively trained to practice responsible alcohol retailing practices put patrons and others at risk of harm from alcohol related injuries or death. The problem is that the perceptions and attitudes of waiters who serve alcohol regarding self-learning as a strategy to prevent patron intoxication are not known; the purpose of this qualitative case study was to explore these perceptions. The study utilized in-depth semi-structured interviews with 23 waiters who utilized a self-learning tool about preventing patron intoxication. The waiters perceived that this self-learning tool was a good training solution, that it would be beneficial if implemented, that the tool could be used to improve public safety, and that its specific data on patron behavior and BAC levels were helpful. The participants also indicated that there would be challenges to implementing such a tool, including the waiters&rsquo; assertiveness and social aptness. As a whole, the researcher recommended that this tool be implemented across the country to improve waiter knowledge and patron safety. For future research, the researcher recommended that the study be expanded to include the perceptions of waiters across the country, the perceptions of those who underwent this training more than a year ago, and that the learning tool be adapted for different learning styles.</p>

<p> Estudiar c&oacute;mo las mujeres ejercen el liderazgo educativo es necesario para reconocer su influencia y poder de transformaci&oacute;n en los diversos escenarios laborales. Al analizar los contextos en los cuales se manifiesta su liderazgo se pueden delinear oportunidades para la adaptaci&oacute;n transdisciplinaria en el campo de la salud. </p><p> El enfoque de esta investigaci&oacute;n gir&oacute; en torno a la trayectoria profesional de Judith Danielsen de Lugo, una mujer, educadora en salud y profesora que ocup&oacute; m&uacute;ltiples puestos de liderazgo en Puerto Rico a partir de la d&eacute;cada de los 50. Con tal fin, se indag&oacute; respecto a: c&oacute;mo las acciones de su trayectoria profesional la caracterizan como l&iacute;der al ejercer las dimensiones del liderazgo educativo; los elementos hist&oacute;ricos, sociales y culturales que se desarrollaron a lo largo de su trayectoria profesional; sus contribuciones a la pr&aacute;ctica profesional de la Educaci&oacute;n en Salud y los desaf&iacute;os y cuestionamientos que se plantean con su liderazgo educativo para el desarrollo y el avance de la salud p&uacute;blica en Puerto Rico. </p><p> La investigaci&oacute;n se fundament&oacute; en los est&aacute;ndares de liderazgo educativo establecidos en el 2011 por el <i>Educational Leadership Constituent Council</i> [ELCC].

<p> The high incidence of medical and surgical errors in U.S. hospitals and clinics affects patients&rsquo; safety. Not enough is known about the relationship between physician characteristics and medical error rates. The purpose of this quantitative correlational study was to examine the relationship between selected physician characteristics and surgical errors in U.S. hospitals. The ecological model was used to understand personal and systemic factors that might be related to the incidence of surgical errors. Archived data from the National Practitioner Data Bank database of physician surgical errors were analyzed using bivariate and multivariate logistic regression analyses. Independent variables included physicians&rsquo; home state, state of license, field of license, age group, and graduation year group. The dependent variable was surgical medical errors. Physicians&rsquo; field of license and state of license were significantly associated with surgical error. Findings contribute to the knowledge base regarding the relationship between physician characteristics and surgical medical errors, and findings may be used to improve patient safety and medical care.</p>

<p> High blood pressure (HBP) is a worldwide concern in many countries (Keamey, et al., 2005). HBP is likely to be higher in underdeveloped countries, specifically in Africa (Addo, Smeeth, &amp; Leon, 2007; Kearney, et al.,2005; World Health Organization [WHO], 2015). The prevalence of HBP in South Africa is 21%, which is about 6 million individuals (Steyn, Gaziano, Bradshaw, Laubscher, &amp; Fourier, 2001). The purpose of the study is to examine the predictive factors of HBP among older adults in South Africa. This cross-sectional study used secondary data from the World Health Organization (WHO &amp; Phaswana-Mafaya, 2008). The total number of participants included in this sample was 2,145 adults age 60 and over, of which females comprise 59%. The average age was 69.50 years (<i>SD= 7.63</i>). The prevalence of reporting HBP among respondents was 37%. The multivariate analysis shows that, when other factors are controlled, being female, having a larger waist circumference, having a diagnosis of diabetes and depression, and urban residence significantly predicted HBP among older South Africans. When comparing men and women, the results of the logistic regression shows that the decrease of odds of having HBP among men who have diabetes and depression is less than the decrease of odds of having HBP among women who have diabetes and depression. These findings indicate that the risk factors, diabetes and depression, have a bigger effect on females compared to males. The results of the study will help to implement primary HBP prevention targeting South African older adult females who have been diagnosed with diabetes, depression, and who live in urban areas.</p><p>

<p> While obesity is a nationwide phenomenon, African Americans &ndash; especially women &ndash; continue to be more severely affected than any other ethnic group. According to the Centers for Disease Control and Prevention, over 20% of African American women are obese compared to 15.6% of Caucasian women. The church is an important community center for many African Americans, and is often a site for health promotion programs, though little is known of the effectiveness of these programs. The purpose of this qualitative study was to study the experiences and attitudes of African American women who have gone through a church-based weight-loss program. Questions were asked about the cultural, environmental and social barriers to weight loss, and the components of effective church-based weight loss programs. Using a phenomenological approach, this study was designed to capture new data for the development of sustainable church-based weight-loss programs. The theory of social support was used as a theoretical framework. The major themes arising from the data concerned the importance of: (a) social support on all levels; (b) the involvement of the pastor, his spouse, or other church leadership; (c) the inclusion of weight-loss participants in program design; (d) a holistic program design to meet the needs of the entire family; and (e) a culturally sensitive program. The inclusion of all these elements is recommended for future programs. The social change implication is that these recommendations could be helpful in the design, development, and implementation of sustainable church-based weight-loss programs for African American women.</p><p>

<p> Caregivers&rsquo; compliance with polio vaccine regimens and timely receipt of the recommended 4 doses of polio vaccine are pivotal to eliminating polio. This cross sectional study, conducted in Lagos State, Nigeria, examined polio vaccine compliance and demographic attributes of caregivers&rsquo; for statistically significant associations. Using an adapted health belief model theoretical framework, 1,200 participants were recruited from well-baby clinics in 8 local government areas in Lagos State. Participants completed a brief demographic survey providing data on caregivers&rsquo; age, gender, residence (rural or urban), and their level of education as well as records from their children&rsquo;s immunization cards. Data obtained were tested for associations between caregiver&rsquo;s demographic information and their children&rsquo;s receipt of polio doses within specified timelines using chi-square and logistic regression analysis. Fisher&rsquo;s exact analysis were conducted for variables with frequencies less than 5. The only significant association recorded was between the receipt of Polio Dose A and location of caregivers&rsquo; residence: Rural dwelling caregivers were less likely to receive the first dose of polio. Results showed Polio Dose D to be the dose most likely received in an untimely manner as well as most likely missed of the 4 doses. Logistic regression analysis did not show any variable to be of greater odds in predicting completion of the 4 doses or compliance with timelines of their receipt. Study&rsquo;s results may inspire polio program planners to develop interventions that broaden the immunization coverage for rural dwellers to include nontraditional maternity locations. Positive social change will ensue by the improvement caregivers&rsquo; compliance with full polio dose receipts with timelines, maximizing immunity. </p><p>

<p> The Human Papillomavirus (HPV) is a common sexually transmitted infection (STI) and etiological agent of cervical cancer. It has been suggested that religiosity may promote a generalized disassociation between all STIs/STDs, including HPV, and personal relevance thus contributing to lower levels of HPV awareness and knowledge among certain groups. This study sought to identify the role of religiosity as a predictor of HPV awareness and knowledge among women in a Christian university. Religiosity was defined and measured using the Duke University Religion Index (DUREL). The schemata and social identity theories provided the theoretical framework for this study. A total of 173 women completed the modified survey instrument to assess level of HPV awareness and knowledge, attitudes toward premarital sex, and level of religiosity. Multiple linear regression analysis was used to test the hypotheses. Religiosity, as defined by the intrinsic religiosity subscale of the DUREL significantly contributed to HPV awareness (<i>p</i> = .002) and HPV knowledge (<i>p</i> = .036). The positive social change implications of this study include a better understanding of the role of religiosity in HPV awareness and knowledge; consideration of religiosity in dissemination of health information by informing public health policies and programs to ensure adequate and culturally relevant education and awareness about HPV transmission, HPV-related cancers, and HPV vaccination.</p><p>

<p> Public health leaders lead a diverse workforce and organizations that are comprehensive in their breadth and scope of services. The purpose of this descriptive quantitative study was to describe the transformational and transactional leadership behaviors of federal public health leaders, their coaching practices, and the relationship between those leadership and coaching behaviors. Researcher recruited a convenience sample of 91 U.S. Public Health Service (USPHS) officers from training events between March-July 2014. Participants self-selected to voluntarily complete an internet-based survey comprising a researcher-designed questionnaire, the Multifactor Leadership Questionnaire 5X Form, and Get Fit for Coaching self-assessment. The first two research questions related to leadership and coaching behaviors were analyzed in SPSS 22 using Kruskal-Wallis H, Yates&rsquo; correction, and Monte Carlo significance tests. The Pearson&rsquo;s product-moment correlation analyzed the third research question examining the relationship between leadership and coaching behaviors. No difference was found in the leadership or coaching behaviors of junior and senior officers when examined by actual rank or seniority. The data revealed several relationships between leadership and coaching behaviors, with significant correlations found for 24 dichotomous pairs, indicating transformational and constructive transactional leadership and coaching behaviors as similar, complementary, and interrelated. The findings showed the act of providing feedback improved performance, while failure to take action or implement change stifles learning and growth. Recommendations for future research included: examining these behaviors among non-uniformed and non-federal public health leaders; exploring their leadership outcomes; and the inclusion of the 360-assessment to validate the self-reported leader data.</p><p>
