In this study, methods of decreasing highly preferred sedentary behaviors were compared and the consequent effects on activity choice were examined. Following free choice of sedentary and physical activities, 34 obese children either were positively reinforced for decreases in high-preference sedentary activity, were punished for high-preference sedentary activity, had access to high-preference sedentary activity restricted, or had no contingencies on activity (control group). Children randomized to reinforcement and punishment were more physically active on intervention days than the control group. Liking for targeted sedentary activity decreased in the reinforcement group, but increased in the restriction and control groups. Results suggest that reinforcing decreases in high-preference sedentary activity can increase physical activity and decrease liking for targeted sedentary activities.
EPSTEIN, LEONARD H, MICHELLE D MYERS,KATARINA ANDERSON. The association of maternal psychopathology and family socioeconomic status with psychological problems in obese children. Obes Res, 1996;4:65-74. In an earlier study we found parental psychiatric symptoms to be a better correlate of behavioral problems in obese children than either child or parental obesity. This study sought to extend this research by assessing the association of general maternal distress, specific maternal psychopathology, family socioeconomic status and child obesity with the psychological problems of 152 children seeking treatment for obesity in two cohorts. Child psychological problems were measured using the Child Behavior Checklist/4-18 (CBCL) in each cohort. In sample 1 maternal general psychiatric symptoms were measured using the Cornell Medical Index (psychiatric subscales) and the Inventory of Interpersonal Problems whereas specific psychopathology was assessed with the Beck Depression Inventory and the Bulimia Test. In sample 2 the Symptom Checklist-90 and Binge Eating Scale provided general and specific measures of psychopathology. In the combined sample, 58% percent of the boys and 44 % of the girls met criteria on at least one CBCL behavioral problem scale, with Social Problems the most prevalent problem in both boys and girls. For both samples, child obesity did not account for any variance in child psychosocial problems beyond that accounted for by maternal psychopathology and family SES. Family SES accounted for a significant increment in variance in child behavioral problems in only two scales. This study systematically replicates previous research, adding support for a broader conceptualization of factors that influence psychological problems in obese treatment-seeking children than one which focuses on child obesity.
The primary goal of childhood obesity interventions is regulation of body weight and fat with adequate nutrition for growth and development. Ideally, these interventions are associated with positive changes in the physiologic and psychological sequelae of obesity. To contribute to long-term weight maintenance, interventions should modify eating and exercise behaviors such that new, healthier behaviors develop and replace unhealthy behaviors, thereby allowing healthier behaviors to persist throughout development and into adulthood. This overview of pediatric obesity treatment, using predominantly randomized, controlled studies, highlights important contributions and developments in primarily dietary, activity, and behavior change interventions, and identifies characteristics of successful treatment and maintenance interventions. Potential positive (eg, reduction in blood pressure, serum lipids, and insulin resistance) and negative (eg, development of disordered eating patterns) side effects of treatment also are described. Recommendations for improving implementation of childhood obesity treatments, including application of behavioral choice theory, improving knowledge of response extinction and recovery in regards to behavior relapse, individualization of treatment, and integration of basic science with clinical outcome research, are discussed.
This paper reviews the use of exercise programs with obese children and adolescents. Studies included for review met two criteria: 1) children or adolescents were defined as obese using objective criteria for obesity, and 2) obese children or adolescents were provided either different types of exercise programs or an exercise program compared with a no-exercise control condition. Thirteen controlled outcome studies were identified. Experimental design, methods, and outcomes are presented and evaluated for each study. Factors that should be considered in research testing exercise interventions are discussed, including adherence, diet, age, gender, and type of exercise. In addition, the potential for exercise programs in the prevention of obesity in childhood and adolescence is discussed. The results support the continued use of exercise in combination with diet for child and adolescent obesity treatment, but the limited number of controlled studies indicates the need for more research in the area. The potential for exercise programs in the prevention of obesity in childhood and adolescence is discussed.
