Healthy Lifestyle Behaviors and Disparities between the United States mainland compared to Puerto Rico, Guam, and United States Virgin Islands (i. e., United States territories)

Background: No studies have compared the lifestyle behaviors between Puerto Rico, Guam, and the U. S. Virgin Islands to that of the United States mainland. Documenting and addressing health disparities between these geographically and culturally distinct areas are important public health objectives. Differences in health status between and among the United States mainland and territories merit systematic and careful analyses. Methods: Four key healthy lifestyle characteristics include tobacco use, body mass index, physical activity, and fruit/vegetable consumption. Data from the 2009 Behavioral Risk Factor Surveillance System (N=420,481) were used to examine United States mainland and territorial differences among the four key healthy lifestyle behaviors. Descriptive statistics were summarized with chi-square tests for independence and multiple adjusted logistic regression models were used to examine differences in health compliance rates while controlling for age, gender, income, and education. Frequencies determined whether Healthy People 2010 goals were met by each location. Results: Differences were found between the United States mainland and territories for smoking rates, body mass index, physical activity, and consumption of fruit/vegetables. None of the countries met all four Healthy People 2010 goals. Discussion: Even though, each location had unique challenges, Puerto Ricans’ health behaviors were significantly less favorable than residents in the other countries. We document prevalence rates and differences by country for each of the four healthy lifestyle characteristics. This study highlights the need for more research in these understudied areas as well as the importance of effective health promotion and disease prevention programs for all United States citizens including the mainland and all territories

The Construct and Predictive Validity of Psychosocial Correlates of Television Viewing

Background: Many studies have examined the consequences of prolonged television viewing, but few studies have examined the psychological states that contribute to this behavior. In this study, we evaluated the construct and predictive validity of psychosocial correlates of television viewing in a population of African American (AA) breast cancer survivors (BCS). Methods: AA BCS (N = 342, Mean age = 54 years) completed measures of decisional balance, self-efficacy, family support, and time spent watching television online. Exploratory structural equation modeling (ESEM) was used to examine the construct and predictive validity as well as the differential item functioning of the instruments among population subgroups. Results: The construct validity of the measures was supported among subgroups. The scales were measuring the construct similarly among the education and body size groups, but not among age groups. Subsequent analysis indicated that pros (β = -0.19, P \u3c 0.05), cons (β = 0.18, P \u3c 0.05), and self-efficacy (β = -0.16, P \u3c 0.05) were significantly associated with time spent watching television. Conclusions: Minor modifications may be needed to support the validity and reliability of the decisional balance and self-efficacy subscales among older survivors. More studies are needed to modify these measures to establish sufficient levels of construct and predictive validity in this population

Lifestyle factors and ovarian cancer outcomes

Purpose: Few studies have reported on the lifestyle characteristics of ovarian cancer survivors. The objectives of this study were to characterize the associations between physical activity (PA) and body size (BS) with health-related quality of life (HRQOL) and ovarian cancer recurrence in a sample of regional and distal stage ovarian cancer survivors. Methods: Epithelial ovarian cancer survivors in their first clinical remission, with no evidence of recurrent disease were identified from The University of Texas MD Anderson Cancer Center tumor registry. A total of 51 survivors consented to participate in a battery of self-reported questionnaires. Trained staff collected data on anthropometric and recurrence data were collected from the tumor registry. Generalized linear models were used to assess the relationship between PA, BS, and HRQOL. Cox proportional hazard models were used to assess the associations between PA, BS, and recurrence-free survival. Results: Most (59%) women were overweight or obese (BMI \u3c 25 kg/m2) , 49% met current guidelines for PA (150 minutes of moderate to vigorous PA/week), and 29% displayed characteristics of abdominal obesity (\u3e88 centimeters). Women who were not obese reported significantly higher (better) overall HRQOL (point difference = 10.8, P \u3c 0.05) and mental health (point difference = 12.4, P \u3c 0.05) scores than women who were obese. Elevated waist circumference and physical activity were not significantly associated with HRQOL outcomes and we did not find any associations between lifestyle behaviors and recurrence free survival (all P \u3e 0.05). Conclusions: Ovarian cancer survivors with characteristics of overall and abdominal obesity may be at risk for deficits in HRQOL and could benefit from interventions designed to reduce weight. More research is needed to determine whether meeting guidelines for physical activity is associated with improvements in health outcomes this population

Impact of Booster Breaks and Computer Prompts on Physical Activity and Sedentary Behavior Among Desk-Based Workers: A Cluster-Randomized Controlled Trial

Introduction The 15-minute work break provides an opportunity to promote health, yet few studies have examined this part of the workday. We studied physical activity and sedentary behavior among office workers and compared the results of the Booster Break program with those of a second intervention and a control group to determine whether the Booster Break program improved physical and behavioral health outcomes. Methods We conducted a 3-arm, cluster-randomized controlled trial at 4 worksites in Texas from 2010 through 2013 to compare a group-based, structured Booster Break program to an individual-based computer-prompt intervention and a usual-break control group; we analyzed physiologic, behavioral, and employee measures such as work social support, quality of life, and perceived stress. We also identified consistent and inconsistent attendees of the Booster Break sessions. Results We obtained data from 175 participants (mean age, 43 y; 67% racial/ethnic minority). Compared with the other groups, the consistent Booster Break attendees had greater weekly pedometer counts (P \u3c .001), significant decreases in sedentary behavior and self-reported leisure-time physical activity (P \u3c .001), and a significant increase in triglyceride concentrations (P = .02) (levels remained within the normal range). Usual-break participants significantly increased their body mass index, whereas Booster Break participants maintained body mass index status during the 6 months. Overall, Booster Break participants were 6.8 and 4.3 times more likely to have decreases in BMI and weekend sedentary time, respectively, than usual-break participants. Conclusion Findings varied among the 3 study groups; however, results indicate the potential for consistent attendees of the Booster Break intervention to achieve significant, positive changes related to physical activity, sedentary behavior, and body mass index

Organizational Culture and Implications for Workplace Interventions to Reduce Sitting Time Among Office-Based Workers: A Systematic Review

Background: Time spent in sedentary behaviors is an independent risk factor for several chronic diseases (e.g., cardiometabolic diseases, obesity, type 2 diabetes, and hypertension). Recently, interventions to reduce sitting time at work (a prominent sedentary behavior) have been developed and tested. Organizational culture plays a critical role in the success of workplace interventions. However, there are a limited number of studies that have examined the role of organizational culture in reducing sitting time in the workplace.Objectives: Therefore, in this systematic review, we summarized the empirical literature investigating organizational culture and sedentary behavior in the workplace and identify gaps in the knowledge base.Methods: We described the procedures of our systematic review and included two study flow diagrams that detailed the step by step process. Combinations of several search terms were used; the databases searched were PubMed, Medline, Academic Search Complete, and Google Scholar. We started with thousands of citations. After applying the inclusion and exclusion criteria, eight relevant articles were identified.Results: For each identified article, the data extracted included citation, sample, objective, intervention, assessment of organizational culture and workplace sitting, findings, and implications. Each article was rated for risk of bias by population, intervention, comparator, outcomes, and study design (PICOS) analysis. The classification for each study was either: high-, moderate-, or low-quality evidence. Given the paucity of data, no definitive conclusions were presented; however, positive trends were highlighted.Conclusions: Work place interventions to reduce sitting time at work may benefit from considering elements of organizational culture; however, the evidence to date is sparse and more high-quality studies in this area are needed. To advance the field of workplace health promotion, organizational culture, and interventions to reduce sitting at work, we present 11 recommendations

Neighborhood disadvantage, physical activity barriers, and physical activity among African American breast cancer survivors

In view of evidence that African American cancer survivors experience the greatest challenges in maintaining adequate levels of physical activity, this cross-sectional study was designed to determine whether individual and residential environment characteristics are associated with physical activity in this population. A total of 275 breast cancer survivors completed self-report items measuring sociodemographic variables, physical activity, and select barriers to physical activity in Spring of 2012. Neighborhood disadvantage variables were extracted from national databases. Regression models were computed to assess relationships. Traditional correlates of smoking status and the presence of health complications were associated with physical activity. In addition, the relative number of renters versus homeowners in one's neighborhood was associated with lower levels of physical activity in the context of individual level barriers (i.e., interest and space), which were also associated with lower levels of physical activity. Higher renter rates and individual barriers both contribute to lower levels of physical activity in African American breast cancer survivors. These data suggest that the potential for constant residential turnover (via rentership) and perceived barriers may increase physical inactivity even where facilities may be available

Is There a Relationship Between Family Structure and Substance Use Among Public Middle School Students?

We investigated the relationship between family structure and substance use in a sample of 2,138 public middle school students in a southern state. The CDC Middle School Youth Risk Behavior Survey was utilized and adjusted logistic regression models were created separately for four race/gender categories (African American females/males, and Caucasian females/males) to examine associations among selected drug use variables (tobacco, alcohol, marijuana and inhalants). Analyses were adjusted for social economic status. Results suggested differences (p .05) among race/gender groups for the protective effect of living in an intact family (both mother and father, real or adoptive) regarding substance use among middle school students. In addition, family structure appeared to have a stronger relationship with substance use for Caucasians as opposed to African American adolescents. Caucasian adolescents living in cohabitated family households were more likely to report substance use, when compared to those living in intact two-parent households. Adolescents who are undergoing parental divorce may need special attention as they transition into new family structures

Middle school students’ perceptions of quality of life

Data are reported on 2278 public middle school students in South Carolina, U.S.A. Levels and demographic effects on their satisfaction with their overall lives as well as five specific domains (family, friends, self, school, and living environment) were assessed. Similar to findings with adults and high school students, most middle schoolers reported positive levels of global and domain-specific life satisfaction. Although statistically significant in some cases, the practical significance of the demographic variables was limited. Many middle schoolers reported particular dissatisfaction with their school experiences. Copyright Springer 2005adolescents, demographics, perceived quality of life,
