Perceived Discrimination and Hypertension Among African Americans in the Jackson Heart Study

OBJECTIVES Using Jackson Heart Study data, we examined whether perceived discrimination was associated with prevalent hypertension in African Americans. METHODS Everyday discrimination, lifetime discrimination, burden of discrimination, and stress from discrimination were examined among 4939 participants aged 35 to 84 years (women = 3123; men = 1816). We estimated prevalence ratios of hypertension by discrimination, and adjusted for age, gender, socioeconomic status, and risk factors. RESULTS The prevalence of hypertension was 64.0% in women and 59.7% in men. After adjustment for age, gender, and socioeconomic status, lifetime discrimination and burden of discrimination were associated with greater hypertension prevalence (prevalence ratios for highest vs lowest quartile were 1.08 [95% confidence interval (CI) = 1.02, 1.15] and 1.09 [95% CI = 1.02,1.16] for lifetime discrimination and burden of discrimination, respectively). Associations were slightly weakened after adjustment for body mass index and behavioral factors. No associations were observed for everyday discrimination. CONCLUSIONS Further understanding the role of perceived discrimination in the etiology of hypertension may be beneficial in eliminating hypertension disparities.

Exposure to occupational hazards among Hispanics, blacks and non-Hispanic whites in California

Relative risks of exposure to each of six types of occupational injuries and illnesses for Hispanic and Black workers compared to Whites who are not Hispanic were calculated using 1986 California data. Among males, Hispanics faced relative risks of exposure to all hazards adjusted for education and years of work experience of 1.33 (95% CI 1.22, 1.45), while Blacks faced relative risks of 1.17 (1.0, 1.37). Among females, adjusted relative risks were 1.19 (1.09, 1.29) for Hispanics and 1.31 (1.15, 1.50) for Blacks.

A systematic review of interventions to promote physical activity in the preschool setting

Purpose Conduct a systematic review of school-based interventions to promote physical activity in preschoolers. Design and Methods A systematic search of literature between 2002 and 2014 in nine electronic databases and reference lists was conducted using the terms physical activity combined with environment, children, or interventions. Results Fourteen articles were identified. Interventions were environmental, cognitive/behavioral, or a combination. Positive interventions involving preschool children included manipulation of the playground with the number of children playing at one time, markings, or equipment, and goal setting and reinforcement. Practice Implications More research is needed to determine interventions to promote physical activity in preschool children.PURPOSE Conduct a systematic review of school-based interventions to promote physical activity in preschoolers.

Assessing environmental support for better health: Active living opportunity audits in rural communities in the southern United States

OBJECTIVE Leisure-time physical activity in the United States is lower rural areas and the South and has been linked to socioeconomic and environmental aspects of where people live. The purpose of this study is to assess the built environment and policies for physical activity in rural communities. METHODS Eight rural communities in Alabama and Mississippi were assessed in 2011 using the Rural Active Living Assessment (RALA) street segment (SSA), town-wide (TWA), and town program and policies (PPA) assessment tools. Community Health Advisors Trained as Research Partners (CHARPS) and local staff conducted the assessments. The TWA and PPA were scored by domain and total scores. Data were analyzed using descriptive and nonparametric statistics. RESULTS 117 segments were assessed in 22 towns in 8 counties. Built environmental barriers existed in all communities. Sidewalks were available in only 10-40% of the segments. TWA identified parks and playgrounds as the most available community feature. PPA scores indicated few policies for physical activity outside of school settings with mean scores higher in Mississippi compared to Alabama (61 vs. 49, respectively). CONCLUSIONS Multiple components of rural communities can be successfully assessed by CHARPs using RALA tools, providing information about resources and barriers for physical activity.

The impact of neighborhood on physical activity in the Jackson Heart Study.

Physical inactivity is an independent risk factor for many diseases. Most research has focused on individual-level factors for physical activity (PA), but evidence suggests that neighborhood is also important. We examined baseline data collected between 2000 and 2004 from 5236 participants in the Jackson Heart Study to determine the effects of neighborhood on 2 types of PA: Active Living (AL), and Sports and Exercise (Sport) in an all-African American cohort. Participants were georeferenced and data from individual baseline questionnaires and US Census were analyzed using descriptive, bivariate, and multilevel models. In both types of PA, neighborhood factors had an independent and additive effect on AL and Sport. Living in an urban (p=0.003) or neighborhood with a higher percentage of residents with less than a high school education (p<0.001) was inversely associated with AL. There was an inverse interaction effect between individual and lower neighborhood education (p=0.01), as well as between age and urban neighborhoods (p=0.02) on AL. Individual level education (OR=1.30) and per capita income (OR=1.07) increased the odds of moderate-to-high sports. Future studies should focus on what contextual aspects of urban or less educated neighborhoods are influential in determining PA, as well as longitudinal multilevel analyses of neighborhood effects on PA.

Weight loss and improved metabolic outcomes amongst rural African American women in the Deep South: six-month outcomes from a community-based randomized trial

Obesity is highly prevalent in African American women, especially those in the rural southern USA, resulting in persistent health disparities.

The Identity Threat of Weight Stigma in Adolescents

Obesity remains a serious public health issue in adolescents, who may be subjected to weight stigma leading to increased stress and poor health outcomes. Stigma can be detrimental to adolescents during self-identity formation. The purpose of this study was to examine weight stigma in adolescents in light of the Identity Threat Model of Stigma. A cross-sectional correlational design was used to examine the relationships among the variables of weight stigma, psychosocial stress, coping styles, disordered eating, and physical inactivity. Regression modeling and path analysis were used to analyze the data. Over 90% of the sample had scores indicating weight stigma or antifat bias. Avoidant coping style and psychosocial stress predicted disordered eating. The strongest path in the model was from avoidant coping to disordered eating. The Identity Threat Model of Stigma partially explained adolescents’ weight stigma. Nursing practice implications are discussed.

Healthcare Quality: A Concept Analysis.

Worsening quality indicators of health care shake public trust. Although safety and quality of care in hospitals can be improved, healthcare quality remains conceptually and operationally vague. Therefore, the aim of this analysis is to clarify the concept of healthcare quality. Walker and Avants method of concept analysis, the most commonly used in nursing literature, provided the framework. We searched general and medical dictionaries, public domain websites, and 5 academic literature databases. Search terms included health care and quality, as well as healthcare and quality. Peer-reviewed articles and government publications published in English from 2004 to 2016 were included. Exclusion criteria were related concepts, discussions about the need for quality care, gray literature, and conference proceedings. Similar attributes were grouped into themes during analysis. Forty-two relevant articles were analyzed after excluding duplicates and those that did not meet eligibility. Following thematic analysis, 4 defining attributes were identified: (1) effective, (2) safe, (3) culture of excellence, and (4) desired outcomes. Based on these attributes, the definition of healthcare quality is the assessment and provision of effective and safe care, reflected in a culture of excellence, resulting in the attainment of optimal or desired health. This analysis proposes a conceptualization of healthcare quality that defines its implied foundational components and has potential to improve the provision of quality care. Theoretical and practice implications presented promote a fuller, more consistent understanding of the components that are necessary to improve the provision of healthcare and steady public trust.

Concept Analysis of Illness Engulfment in Schizophrenia

Schizophrenia has a significant risk of damaging an individuals self-concept. Through the process of illness engulfment an individuals self-concept becomes reorganized entirely around the experience of having schizophrenia. The purpose of this manuscript is to clarify the structure and function of the concept of illness engulfment in schizophrenia using Walker and Avants (2011) method of concept analysis. Data came from a review of scholarly literature, as well as contemporary and historical art, literature, music, and other media forms. The analysis discussed two defining attributes of experience of illness and impact on self-concept with a total of seven indicators. The article listed antecedents, consequences, and discussed the Modified Engulfment Scale as empirical referents. Fictional cases were developed to illustrate the concept. Finally, the concept of illness engulfment was discussed within the framework of the Roy Adaptation Model.

Barriers to Physical Activity and Healthy Diet Among Children Ages 6 Through 13 in a Mississippi Elementary School

The purpose of this study was to identify barriers to adequate physical activity and a healthy diet, investigate differences in the perceived barriers among subgroups, and determine predictors of high versus low total barrier scores in one inner-city elementary school. A mixed method design was used and included students ages 6 through 13 (n=110) and parents, teachers, and community leaders (n=20). Data were collected using questionnaires and focus groups. Quantitative findings revealed no differences in total barriers based on age, gender, number of parents, or household income; however, subscale differences among groups were noted. Qualitative findings indicated that perceived barriers to physical activity were knowledge-related, and barriers to healthy diet concerned access to healthy foods.
