Motivational interviewing for pediatric obesity: Conceptual issues and evidence review

Counseling by health care professionals represents a potentially important intervention for the prevention and treatment of pediatric obesity. One promising approach to weight-control counseling in pediatric practice is motivational interviewing. This article explores conceptual issues related to the application of motivational interviewing for the prevention and treatment of pediatric obesity. Given the paucity of studies on motivational interviewing and pediatric obesity, we examine what is known about the application of motivational interviewing to modify diet, physical activity, and other behaviors in children and adolescents. We begin with a brief overview of motivational interviewing, describe some nuances of applying this approach to pediatric overweight, and conclude with research and clinical recommendations.

Psychosocial mediation of fruit and vegetable consumption in the body and soul effectiveness trial

In this study the authors examined psychosocial variables as mediators for fruit and vegetable (FV) intake in a clustered, randomized effectiveness trial conducted in African American churches. The study sample included 14 churches (8 intervention and 6 control) with 470 participants from the intervention churches and 285 participants from the control churches. The outcome of FV intake and the proposed mediators were measured at baseline and at 6-month follow-up. Structural equation modeling indicated that the intervention had direct effects on social support, self-efficacy, and autonomous motivation; these variables also had direct effects on FV intake. Applying the M. E. Sobel (1982) formula to test significant mediated effects, the authors confirmed that social support and self-efficacy were significant mediators but that autonomous motivation was not. Social support and self-efficacy partially mediated 20.9% of the total effect of the intervention on changes in FV intake. The results support the use of strategies to increase social support and self-efficacy in dietary intervention programs.

Effects of a holistic health program on women's physical activity and mental and spiritual health

Intervention studies aimed at promoting increased physical activity have been trialled in many different settings including primary care, worksites and the community. Churches are also potential settings for physical activity promotion. However, little is known about the effectiveness of this setting for promoting physical activity, particularly in Australia. The purpose of this study was to evaluate the effectiveness of a mind, body and spiritually based health promotion program in increasing physical activity and promoting mental and spiritual health. Nineteen women completed the 8-week intervention, and 30 women in a non-health related 8-week program at the same church comprised a comparison group. Pre- and post-program surveys assessed outcome measures. Between-group differences over time were examined using one-way MANOVA's. Physical activity was higher in the intervention group than the comparison group. In contrast to the comparison group, both mental health (depression symptoms) and spiritual health improved significantly more among intervention participants. The data highlight the potential for a church-based setting and holistic approach to health promotion as a successful means of increasing physical activity and promoting mental and spiritual health among Australian women.

Body and soul. A dietary intervention conducted through African-American churches

OBJECTIVES

Body and Soul was a collaborative effort among two research universities, a national voluntary agency (American Cancer Society), and the National Institutes of Health to disseminate and evaluate under real-world conditions the impact of previously developed dietary interventions for African Americans.

METHODS

Body and Soul was constructed from two successful research-based interventions conducted in African-American churches. Components deemed essential from the prior interventions were combined, and then tested in a cluster randomized-effectiveness trial. The primary outcome was fruit and vegetable intake measured with two types of food frequency questionnaires at baseline and 6-month follow-up.

RESULTS

At the 6-month follow-up, intervention participants showed significantly greater fruit and vegetable (F&V) intake relative to controls. Post-test differences were 0.7 and 1.4 servings for the 2-item and 17-item F&V frequency measures, respectively. Statistically significant positive changes in fat intake, motivation to eat F&V, social support, and efficacy to eat F&V were also observed.

CONCLUSIONS

The results suggest that research-based interventions, delivered collaboratively by community volunteers and a health-related voluntary agency, can be effectively implemented under real-world conditions.
