- Brief Summary
The purpose of the study was to examine the influence of step goals with pedometers to improve children's weight loss, physical activity, and psychosocial health during behavioral treatment. Children with overweight or obesity were assigned to receive the behavioral treatment alone, plus pedometers, or plus pedometers with step goals.
- Detailed Description
A total of 105 overweight and obese children ages 8 to 17 years participated in a 10-week family-based weight management intervention focusing on physical activity, nutrition, and behavioral modification. A quasi-experimental design was used to group cohorts into three conditions: two cohorts had no pedometer (n=24); two cohorts had pedometer only (n=25); and four cohorts had pedometer with step goals (i.e. 500 steps/day weekly increase above baseline; n=56). Height and weight were measured at baseline and week 10 and used to calculate body mass index (BMI). Analysis of covariance was performed to examine difference by condition for change in weight, BMI, and BMI z-score, controlling for age and baseline value. Differences in steps/day and psychosocial health were compared between the two pedometer conditions.

Group Intervention Description Pedometer Only Pedometer In addition to participating in the family-based weight management intervention, participants were given a pedometer and instructions at session 1. Participants were asked to wear the pedometer every day for the entirety of the program and return at session 10. No step goals were provided. No Pedometer Family-based weight management Participants only participated in the family-based weight management intervention. Participants were not given a pedometer or step goals. Pedometer Plus Step Goals Pedometer In addition to participating in the family-based weight management intervention, participants were given a pedometer and instructions at session 1. Participants were asked to wear the pedometer every day for the entirety of the program and return at session 10. Participants were given individualized step goals to increase their activity by 500 steps each week (above baseline calculated as average daily steps/day during week 1). Pedometer Plus Step Goals Family-based weight management In addition to participating in the family-based weight management intervention, participants were given a pedometer and instructions at session 1. Participants were asked to wear the pedometer every day for the entirety of the program and return at session 10. Participants were given individualized step goals to increase their activity by 500 steps each week (above baseline calculated as average daily steps/day during week 1). Pedometer Only Family-based weight management In addition to participating in the family-based weight management intervention, participants were given a pedometer and instructions at session 1. Participants were asked to wear the pedometer every day for the entirety of the program and return at session 10. No step goals were provided. Pedometer Plus Step Goals Individualized step goals In addition to participating in the family-based weight management intervention, participants were given a pedometer and instructions at session 1. Participants were asked to wear the pedometer every day for the entirety of the program and return at session 10. Participants were given individualized step goals to increase their activity by 500 steps each week (above baseline calculated as average daily steps/day during week 1).
- Primary Outcome Measures
Name Time Method BMI Z-score Change 10 weeks Height was measured at sessions 1 and 10 using a stadiometer. Weight was measured at each session using a calibrated scale. BMI z-score was calculated from the Centers for Disease Control and Prevention macro program based on the sex, height, and age of the child. Change was calculated as difference between baseline and end of 10-week study.
- Secondary Outcome Measures
Name Time Method BMI Change 10 weeks BMI was calculated as weight in kg divided by height in meters squared. Change was calculated as difference between baseline and end of 10-week study.
Physical Activity Change 10 weeks Physical activity was measured in the pedometer only and pedometer plus goals groups using an Omron pedometer (Omron HJ-324U, Omron Healthcare, Lake Forest, IL). Change was calculated as difference between baseline and end of 10-week study.
Quality of Life Kidscreen-10 Index Change 10 weeks Health-related quality of life was measured using the Kidscreen-10 Index. Change was calculated as difference between baseline and end of 10-week study. the scale ranged from 0 to 15, with higher values indicating a better outcome.
Body Weight Change 10 weeks Weight was measured using a calibrated scale. Change was calculated as difference between baseline and end of 10-week study.
Physical Activity Enjoyment Change 10 weeks Physical activity enjoyment was measured using the Physical Activity Enjoyment Scale (PACES). Change was calculated as difference between baseline and end of 10-week study. The scale ranged from 0 to 32, with higher values indicating a better outcome.
Subjective Health Change 10 weeks Subjective health was measured using a 1-item Likert scale ("In general, how would you say your health is?"). Change was calculated as difference between baseline and end of 10-week study. The scale ranged from 0 to 4, with higher values indicating a better outcome.
