BACKGROUND Inexpensive, reliable objective methods are needed to measure physical activity (PA) in large scale trials. This study compared the number of pedometer step counts with accelerometer data in pregnant women in free-living conditions to assess agreement between these measures. METHODS Pregnant women (n = 58) with body mass index ≥25 kg/m(2) at median 13 weeks' gestation wore a GT1M A...

The study was undertaken to evaluate (a) the reliability of pedometer data and reactivity of children to wearing a pedometer, (b) the effectiveness of a missing data replacement procedure, and (c) the validity of the Leisure Time Exercise Questionnaire (LTEQ). Six days of pedometer data were collected from 299 middle-school children, followed by administration of the LTEQ. Six days of pedometer...

We examined the reliability of scores from physical activity monitors in a sample of 193 individuals with multiple sclerosis (MS) who wore a pedometer and an accelerometer for a 7-day period. There were no significant differences among days for the pedometer (p = .12) or the accelerometer (p = .15) indicating that week and weekend days can be analyzed in a single intra-class correlation (ICC) a...

OBJECTIVE To examine whether wearing a pedometer was associated with higher objectively-measured physical activity (PA) among adolescents independent of other behavior change strategies, and whether this association differed by sex or day of wear. METHOD In a parallel-group population-based cohort study, 892 adolescents (43.4% male, mean±SD age, 14.5±0.5years) from Eastern England were recrui...

Objectives: To investigate the influence of wearing a pedometer and recording daily step counts on ambulatory activity. Methods: During the first visit to the laboratory, fifty healthy volunteers, blinded to the study aim, were provided with a sealed pedometer (New-Lifestyles NL-2000) and informed that it was a 'Body Posture Monitor' (sealed condition). Participants wore the pedometer throughou...

OBJECTIVES To determine the effectiveness of a behavior change intervention (BCI) with or without a pedometer in increasing physical activity in sedentary older women. DESIGN Prospective randomized controlled trial. SETTING Primary care, City of Dundee, Scotland. PARTICIPANTS Two hundred four sedentary women aged 70 and older. INTERVENTIONS Six months of BCI, BCI plus pedometer (pedomet...

BACKGROUND The purpose of this study was to determine if a short-term pedometer-based intervention results in immediate increases in time spent in moderate-to-vigorous physical activity (MVPA) compared to a minimal educational intervention. METHODS A sample of 43 overweight adults 35 to 64 years of age participated in a one week pedometer-based feasibility trial monitored by accelerometry. Pa...

INTRODUCTION Regular pedometer use can help initiate and maintain regular walking activity that can lead to a number of health-related benefits. The primary health care setting has been found to be an ideal venue in which to counsel low-active individuals for physical activity. AIM To examine general practitioners' (GPs) views on the role of pedometers in health promotion. METHODS Fifteen G...

BACKGROUND Due to high rates of inactivity and related chronic illnesses among Latinas, the current study examined the feasibility and acceptability of using pedometers as an intervention tool in this underserved population. METHODS Data were taken from a larger randomized, controlled trial2 and focused on the subsample of participants (N = 43) who were randomly assigned to receive a physical...

BACKGROUND Physical activity (PA) is important for controlling childhood obesity, but a comprehensive PA model for school-aged children is lacking. OBJECTIVES Guided by the youth PA promotion (YPAP) model, this study estimated the direct and indirect effects of self-efficacy, enjoyment, parental influence, and environment on self-reported PA and pedometer steps. A secondary purpose was to exp...
