Adolescent Sedentary Behaviors: Correlates Differ for Television Viewing and Computer Use

PURPOSE Sedentary behavior is associated with obesity in youth. Understanding correlates of specific sedentary behaviors can inform the development of interventions to reduce sedentary time. The current research examines correlates of leisure computer use and television viewing among adolescents in California. METHODS Using data from the 2005 California Health Interview Survey, we examined individual, family, and environmental correlates of two sedentary behaviors among 4,029 adolescents: leisure computer use and television watching. RESULTS Linear regression analyses adjusted for a range of factors indicated several differences in the correlates of television watching and computer use. Correlates of additional time spent watching television included male sex, American Indian and African American race, lower household income, lower levels of physical activity, lower parent educational attainment, and additional hours worked by parents. Correlates of a greater amount of time spent using the computer for fun included older age, Asian race, higher household income, lower levels of physical activity, less parental knowledge of free-time activities, and living in neighborhoods with higher proportions of nonwhite residents and higher proportions of low-income residents. Only physical activity was associated similarly with both watching television and computer use. CONCLUSIONS These results suggest that correlates of time spent on television watching and leisure computer use are different. Reducing screen time is a potentially successful strategy in combating childhood obesity, and understanding differences in the correlates of different screen time behaviors can inform the development of more effective interventions to reduce sedentary time.

Income Disparities in Obesity Trends Among California Adolescents

OBJECTIVES We assessed income-specific trends in obesity rates among a diverse population of California adolescents. METHODS We used data from 17,535 adolescents who responded to the California Health Interview Survey between 2001 and 2007 to examine disparities in obesity prevalence by family income and gender. RESULTS Between 2001 and 2007, obesity prevalence significantly increased among lower-income adolescents but showed no statistically significant differences among higher-income adolescents after adjustment for age, gender, and race/ethnicity. Although the overall disparity in obesity by family income doubled in this time period, trends were more consistent among male adolescents than among female adolescents. CONCLUSIONS The magnitude of the income disparity in obesity prevalence among California adolescents more than doubled between 2001-2007. The overall leveling off of adolescent obesity prevalence rates could indicate that efforts to decrease childhood obesity are having an impact; however, our results suggest that efforts to prevent childhood obesity may be failing to help adolescents from lower-income families, particularly male adolescents.

The influence of integrated electronic medical records and computerized nursing notes on nurses' time spent in documentation.

We investigated nurses’ time spent in documentation as it relates to the use of electronic charting. A cross-sectional analysis was completed using time and motion data collected during a nursing process improvement initiative for 105 units in 55 hospitals. Ordinary least squares regression with a cluster adjustment revealed very little difference in time spent in documentation with or without the use of electronic medical records or computerized nursing notes. Nurses spent 19% of their time completing documentation, regardless of electronic charting usage, compared with all other categories of care. These findings suggest that integrated electronic medical records and computerized nursing notes do not appear to increase the time nurses spend documenting.

Asthma-related school absenteeism and school concentration of low-income students in California.

Introduction Asthma is one of the leading causes of school absenteeism. Previous studies have shown that school absenteeism is related to family income of individual students. However, there is little research examining whether school absenteeism is related to school-level concentration of low-income students, independent of family income. The objective of this study was to examine whether the proportion of low-income students at a school was related to school absenteeism due to asthma. Methods Using data from the 2007 California Health Interview Survey, a population-based survey of California households, we examined the association between attending schools with high concentrations of low-income students and missing school because of asthma, adjusting for demographic characteristics, asthma severity, and health insurance status. Schools with high concentrations of low-income students were identified on the basis of the percentage of students participating in the free and reduced-price meal program, data publicly available from the California Department of Education. Results Students attending schools with the highest concentrations of low-income students were more likely to miss school because of asthma. Students from low-income families, younger students, those with more frequent asthma symptoms, or those taking prescription asthma medications also were more likely to miss school because of asthma. Conclusion The use of school-level interventions to decrease school absenteeism due to asthma should be explored, especially in schools with high concentrations of low-income students. Potential interventions could include school-based asthma education and disease management or indoor and outdoor air pollution control.

Engaging Frontline Staff in Performance Improvement: The American Organization of Nurse Executives Implementation of Transforming Care at the Bedside Collaborative.

BACKGROUND Process improvement stresses the importance of engaging frontline staff in implementing new processes and methods. Yet questions remain on how to incorporate these activities into the workday of hospital staff or how to create and maintain its commitment. In a 15-month American Organization of Nurse Executives collaborative involving frontline medical/surgical staff from 67 hospitals, Transforming Care at the Bedside (TCAB) was evaluated to assess whether participating units successfully implemented recommended change processes, engaged staff, implemented innovations, and generated support from hospital leadership and staff. METHODS In a mixed-methods analysis, multiple data sources, including leader surveys, unit staff surveys, administrative data, time study data, and collaborative documents were used. RESULTS All units reported establishing unit-based teams, of which >90% succeeded in conducting tests of change, with unit staff selecting topics and making decisions on adoption. Fifty-five percent of unit staff reported participating in unit meetings, and 64%, in tests of change. Unit managers reported substantial increase in staff support for the initiative. An average 36 tests of change were conducted per unit, with 46% of tested innovations sustained, and 20% spread to other units. Some 95% of managers and 97% of chief nursing officers believed that the program had made unit staff more likely to initiate change. Among staff, 83% would encourage adoption of the initiative. CONCLUSIONS Given the strong positive assessment of TCAB, evidence of substantial engagement of staff in the work, and the high volume of innovations tested, implemented, and sustained, TCAB appears to be a productive model for organizing and implementing a program of frontline-led improvement.

Neighborhood, family and individual characteristics related to adolescent park-based physical activity

BACKGROUND Local parks are an important community resource that may influence levels of physical activity among youth. However, few population-based studies have investigated park-based physical activity among youth. PURPOSE This study examines sociodemographic, family, and neighborhood characteristics associated with park-based physical activity among adolescents. METHODS Data were from the 2007 California Health Interview Survey (CHIS), a population-based survey of California households, and were analyzed in 2012-2013 and 2015. This study examined individual (age, gender, race/ethnicity, and nativity), family (household income, parental education, and nativity), and neighborhood characteristics (urbanicity, perceived park availability, perceived park safety, neighborhood income, and racial composition) associated with engaging in park-based physical activity among adolescents. RESULTS In California, 71% of adolescents reported being physically active the last time they visited a park. In adjusted multinomial logistic regression analyses, older adolescents and females were less likely to be physically active in parks. Adolescents with a park within walking distance of home and those with a safe park nearby were more likely to be physically active during a park visit. CONCLUSIONS Park availability and perceptions of park safety are important predictors of engaging in park-based physical activity among adolescents. These findings provide information that can help inform interventions intended to increase physical activity among youth. Strategies that increase availability and safety of parks and other recreation spaces may be particularly effective.

Adolescent Physical Activity: Role of School Support, Role Models, and Social Participation in Racial and Income Disparities

Few youth meet current physical activity recommendations. Protective social factors such as having a role model, social participation, and adult support at school may help promote youth physical activity. This study used data from the 2011-2012 California Health Interview Survey to examine the extent to which role models, social participation, and support at school promote physical activity among groups at risk of inactivity and obesity, specifically low-income youth and youth of color. In a model including all adolescents, those who participated in organizations outside school, did volunteer work, reported higher support from adults at school, and reported having an athlete as a role model were more physically active. However, associations varied by gender, income, and race/ethnicity. These findings suggest that some of these protective social factors, especially school support, may help promote physical activity among Latino, African American, and low-income youth, groups at increased risk of physical inactivity.
