Predictors of Response to an Intervention Modifying Physical Activity and Sedentary Behavior in Overweight/Obese Children: Attitudes vs. Behavior

Gary S. Goldfield

Objective:

To compare liking and other attitudes toward physical activity (PA) and television (TV) viewing versus PA behavior and time viewing TV at baseline as predictors of response to lifestyle intervention in 30, 8 to 12 year old overweight/obese children.

Method:

Secondary analyses from a randomized controlled trial designed to increase PA and reduce sedentary behavior. PA was measured by accelerometers worn by participants every day for 8 weeks. TV viewing at baseline and during intervention was assessed by self-report.

Results:

Multiple regression analyses showed that base rates of PA and TV viewing significantly predicted changes in PA (Beta = .39, P < .05) and TV viewing (Beta = .37, P < .05) during the intervention, even after statistically controlling for child age, gender, body mass index, as well as baseline attitudes and liking of PA and TV viewing. However, self-reported liking of TV viewing and PA, perceived adequacy, and predilection were not predictive of response to intervention.

Conclusions:

Baseline measure of PA and TV viewing behaviors may be better predictors of response to lifestyle intervention than measure of liking and other attitudinal variables of PA. The theoretical and clinical implications of these findings are discussed.

Web-Based Behavioral Intervention Increases Maternal Exercise but Does Not Prevent Excessive Gestational Weight Gain in Previously Sedentary Women

Katie Smith, L. Lanningham-Foster, Amy Welch, and Christina Campbell

Background:

Innovative methods are warranted to optimize prenatal outcomes. This study’s objective was to determine if a web-based behavioral intervention (BI) can prevent excessive gestational weight gain (GWG) by increasing physical activity (PA).

Methods:

Participants were randomized to usual care (UC; n = 21) or BI (n = 24) between 10 to 14 weeks gestation. GWG, PA, and diet were assessed at baseline, mid-, and late pregnancy.

Results:

No differences in GWG or adherence to GWG recommendations presented between groups. Total UC MET-minutes significantly decreased from baseline to late-pregnancy (1,234 ± 372 MET-minutes, P = .013). Mid-pregnancy sustained PA was greater for BI than UC (20-minute PA bouts: 122 ± 106 vs. 46 ± 48 minutes/week, P = .005; 30-minute PA bouts: 74 ± 70 vs. 14 ± 24 minutes/week, P < .001), and greater for BI at mid-pregnancy compared with baseline (20-minute PA bouts: 61.3 ± 21.9; 30-minute PA bouts: 39.6 ± 14.8, both P < .05). BI energy intake at mid-pregnancy significantly increased from baseline (336 ± 127 kcals, P = .04) and was significantly greater than UC (2,503 ± 703 vs. 1,894 ± 594, P = .005).

Conclusions:

Sedentary pregnant women should increase PA but may need additional dietary counseling to prevent excessive GWG.

Operationalizing Environmental Indicators for Physical Activity in Older Adults

Scott Strath, Raymond Isaacs, and Michael J. Greenwald

This qualitative study describes environmental supports and barriers to physical activity in an older adult sample drawn from low- and high-walkable neighborhoods. Thirty-seven individuals age 55 and over were recruited and answered open-ended survey questions, with a subsample invited back to partake in a semistructured interview. Content analysis identified categories and themes linking perceptions of neighborhood-environment characteristics to activity. Emerging categories and themes did not differ across neighborhood walkability, so results are presented for both groups combined. Infrastructure was the most common category identified to encourage activity, specifically, well-maintained sidewalks, bike paths or lanes, and traffic control. Other categories of land use, landscape, and aesthetics were reported. Poorly maintained or missing sidewalks, crosswalks, bike paths or lanes, and traffic safety were categories that discouraged activity. In conclusion, the information obtained is helpful in solidifying which environmental characteristics are important to measure as they relate to activity behavior in an older adult population.

Results From New Zealand’s 2016 Report Card on Physical Activity for Children and Youth

Ralph Maddison, Samantha Marsh, Erica Hinckson, Scott Duncan, Sandra Mandic, Rachael Taylor, and Melody Smith

Background:

In this article, we report the grades for the second New Zealand Report Card on Physical Activity for Children and Youth, which represents a synthesis of available New Zealand evidence across 9 core indicators.

Methods:

An expert panel of physical activity (PA) researchers collated and reviewed available nationally representative survey data between March and May 2016. In the absence of new data, (2014–2016) regional level data were used to inform the direction of existing grades. Grades were assigned based on the percentage of children and youth meeting each indicator: A is 81% to 100%; B is 61% to 80%; C is 41% to 60%, D is 21% to 40%; F is 0% to 20%; INC is Incomplete data.

Results:

Overall PA, Active Play, and Government Initiatives were graded B-; Community Environments was graded B; Sport Participation and School Environment received a C+; Sedentary Behaviors and Family/Peer Support were graded C; and Active Travel was graded C-.

Conclusions:

Overall PA participation was satisfactory for young children but not for youth. The grade for PA decreased slightly from the 2014 report card; however, there was an improvement in grades for built and school environments, which may support regional and national-level initiatives for promoting PA.

Perceived Individual, Social, and Environmental Factors for Physical Activity and Walking

Michelle L. Granner, Patricia A. Sharpe, Brent Hutto, Sara Wilcox, and Cheryl L. Addy

Background:

Few studies have explored associations of individual, social, and environmental factors with physical activity and walking behavior.

Methods:

A random-digit-dial questionnaire, which included selected individual, social, and environmental variables, was administered to 2025 adults, age 18 y and older, in two adjacent counties in a southeastern state. Logistic regressions were conducted adjusting for age, race, sex, education, and employment.

Results:

In multivariate models, somewhat different variables were associated with physical activity versus regular walking. Self-efficacy (OR = 19.19), having an exercise partner (OR = 1.47), recreation facilities (OR = 1.54), and safety of trails from crime (OR = 0.72) were associated with physical activity level; while self-efficacy (OR = 4.22), known walking routes (OR = 1.54), recreation facilities (OR = 1.57-1.59), and safety of trails from crime (OR = 0.69) were associated with regular walking behavior.

Conclusions:

Physical activity and walking behaviors were associated with similar variables in this study.
