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.

Recruitment & Eligibility

Inclusion Criteria

Aged 8-17 years old
BMI ≥ 95th percentile or have a BMI ≥ 85th percentile with comorbidities (e.g. hypertension, heart disease, type 2 diabetes, insulin resistance, sleep apnea, orthopedic problems, or fatty liver disease)

Exclusion Criteria

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.
