PWM: Overview Table: Individual and Family Based Interventions (2006)

Overview Table: Individual and Family Based Interventions

Evidence Summaries for Individual and Family Interventions focus on specific weight loss components (for example, counseling or diet or physical activity recommendations). However, interventions generally include more than one component.

The following table is a summary of the range of studies we analyzed. As you see, most studies examined multi-component interventions. To see our summary of the effectiveness of each component, select the item from the left navigation bar.

Summary Table for Individual and Family Interventions 

Intervention may include one or a combination of components: Dietary (D), Physical Activity (PA), Sedentary Activity (SA) or Behavioral (B) components, Family Counseling (F) or Parent Training or Modeling (PT).

PT

Subjects were randomized to 2 groups: Parent only behavioral sessions, 4 weekly followed by 4 biweekly and then six every sixth week versus child only diet and physical activity instruction, 8 weekly followed by bi-weekly sessions for 10 months---both groups taught by a registered dietician.

Weight, height, %overweight

29 (97%) families in the parent only group behavioral instruction and 21 (70%) in the child diet and physical activity instruction completed the study (p<0.02). Both groups significantly reduced %overweight at 12 months (p<0.001 parent only and p<0.01 child only). Children in the parent only group had a significantly greater reduction in %overweight at 12 months (14.6%) than children in the child only group (8.1% [p<0.03]).

Children were ranked by %overweight and assigned randomly from stratified blocks 3 groups: behavioral, problem solving, or instruction-only. All groups attended 8 weekly 60-minute sessions including games stories and activities to teach treatment objectives. Traffic light diet and self-monitoring of food and activity in all groups. In the behavioral group, behavioral therapy was conducted for 20 minutes including diet information, exercise information, stimulus control, family support, cognitive restructuring, peer relations and maintenance strategies. In the problem-solving group, 20 minutes of problem solving activity was included in the sessions. In the instruction only group 15 minutes of exercise was included in the session.

Weight, height, %overweight, and BMI

Children in problem solving and behavioral groups decreased weight, %overweight and BMI significantly (p<0.05) at 8 weeks. Differences were significantly different between groups: problem solving > behavioral and instruction (p<0.05). Significant differences were maintained at 3 and 6-month follow-up. Only children in the problem-solving group maintained significant differences in %overweight and BMI at 6 months.

Subjects were assigned to three treatment groups according to severity of obesity: Phase I (30 weeks) for severely obese; Phase II (20 weeks) for moderately obese; Phase III (10 weeks) for mildly obese. When goal weight attained (<120% IBW), subjects began Phase IV “maintenance” phase.  Treatment included protein sparing modified fast diet, behavior modification, and progressive exercise program of moderate intensity.

Weight, %IBW, BMI, relative fat (%) and fat free mass (determined by formula using triceps and subscapular skinfolds)

 

69 (95%) completed initial phase of 10, 20 or 30 weeks; 48 (67%; 18M, 30F) completed 1 year program.  Body weight, %IBW, BMI and % fat decreased significantly in all 3 groups by 10 weeks compared to baseline (p<.001).  Percent fat and BMI remained decreased at 52 weeks follow-up (p<.001).

Subjects participated in multi disciplinary weight management program with aerobic exercise alone (AE) or aerobic exercise plus resistance training (RT). Subjects in both groups attended weekly 2-hour sessions. Protein sparing modified fast diet and/or balanced hypocaloric diet (based on initial weight status) and behavior modification. Subjects in AE group were instructed to walk 3 times per week for 60 minutes at 65-70%VO2max (76-80% heart rate).

RT subjects and families participated in moderate intensity progressive exercise including resistance training 1-2 days per week, 8-10 exercises targeting major muscle groups based on Social Cognitive Therapy (Committed to Kids and Trim Kids approach).

Weight, height, %overweight, BMI, %fat by skin folds (RT only)

15 of 19 RT subjects completed 1 year study (78.9%) and 17 of 48 controls completed one year program (35.4%). BMI and %overweight decreased significantly from baseline to 10 weeks and one year in both groups (p<.0001). Weight was significantly lower than baseline at 10 weeks in both groups but only in RT group at one year (p<.001). In RT subjects, %body fat decreased significantly from 42.6% at baseline to 32.6% at 120 weeks and 31.0% at 1 year (p<.0001).
