- Brief Summary
Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Measurements of children and parent dyads are assessed at baseline and at the end (week 24) of the intervention or control periods. Outcome measures include PA, body composition, motor proficiency, central sensory reception and integration (subsample of children only), quality of life and physical activity self-efficacy. PA intervention compliance is monitored using mail-in daily self-report checklists.
- Detailed Description
Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Specifically, approaches that involve the family have been identified as possible areas where further research is needed. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Tips related to scheduling and coping with barriers to daily program implementation are also included. Throughout, parents are contacted by phone once a week (weeks 1-4) and then every other week to provide support in between visits. Measurements of children and parent dyads are assessed at baseline, at 12-weeks of receiving the intervention and at the end (week 24) of the intervention or control periods. PA intervention compliance is monitored using mail-in daily self-report checklists.
Recruitment & Eligibility
- Status
- UNKNOWN
- Sex
- All
- Target Recruitment
- 115
- Having Prader-Willi Syndrome and being between ages 8-15 years. PWS status will be documented by appropriate molecular and cytogenetic testing (i.e., chromosomes, florescence in situ hybridization [FISH] 15, DNA methylation, DNA polymorphism studies)
- Being obese and between ages 8-11 years. Obesity is defined as having a body fat percentage greater than the 95th percentile (McCarthy, H. D., Cole, T. J., Fry, T., Jebb, S. A., & Prentice, A. M. (2006). Body fat reference curves for children. International Journal of Obesity (Lond), 30(4), 598-602).
- Obese children without Prader-Willi Syndrome currently on lipid-lowering medication, diabetes medications, or blood pressure medications.
- Being pregnant

- Primary Outcome Measures
Name Time Method Physical Activity Baseline to 24 weeks PA level: This outcome will be measured using accelerometers which provide detailed information on the temporal patterns (duration, frequency, and intensity) of PA. Data are stored as acceleration counts and data can be downloaded to a personal computer. Youth will use the 4MB GT3X (Actigraph, Pensacola, FL) triaxial activity monitor at the hip for eight consecutive days. Participants should wear the monitor all day while they are awake and remove the monitor when they shower, bathe, swim, or do something that may get the monitor completely wet. The youth and parents will be asked to fill out a log of all the physical activities they engage in during the days they wear the accelerometer. The child will wear the accelerometer for eight days to capture two typical weekend days. Physical activity will be defined as minutes per day of Moderate to Vigorous Physical Activity. Accelerometry cut-points published by Evenson et al. will be used to determine MVPA.
- Secondary Outcome Measures
Name Time Method Quality of life Baseline to 24 weeks will be measured using Pediatric Quality of Life Inventory (PedsQL™) to assess multidimensional constructs covering physical, emotional, mental, social, and behavioral components of well-being and function in youth (Varni, J.W., et al., The PedsQL 4.0 as a pediatric population health measure: feasibility, reliability, and validity. Ambul Pediatr, 2003. 3(6): p. 329-41)
Body composition Baseline to 24 weeks Percentage of body fat will be measured using dual x-ray absorptiometry (DXA) model Lunar Prodigy Advance Plus (GE Healthcare, Milwaukee, WI). For female participants who have had their first menses, a urine pregnancy test will be completed before conducting the DXA scan. A pregnancy test is required by law because the x-rays might be harmful to the fetuses. If the participant is pregnant, she will be excluded from the study as a major study outcome is body composition and the participant will experience changes in body composition because of pregnancy, thus invalidating the study findings.
Motor proficiency Baseline to 24 weeks The Bruininks-Oseretsky Test of Motor Proficiency (BOTMP™-2) is used to evaluate overall motor proficiency. The BOTMP™-2 test measures fine manual control (fine motor precision and fine motor integration), manual coordination (manual dexterity and upper limb coordination), body coordination (bilateral coordination and balance), and strength and agility (running speed and agility and strength). This test also provides an overall motor proficiency score, as well as separate scores for the different domains of motor proficiency (Bruininks, R., Bruininks-Oseretsky test of motor proficiency: examiner's manual. 1978, MN: American Guidance Service). It is expected that significant improvements are demonstrated following completion of the PA intervention in the areas of upper limb coordination, bilateral coordination, balance, running speed, and agility and strength.
Sensory reception and motor integration Baseline to 24 weeks Sensory reception and motor integration will be measured using The Sensory Organization Test. The SOT is designed to identify impairments in one or more of the three sensory systems (i.e., vision, somatosensory, vestibular) that contribute to standing balance. This test has been previously used with pediatric populations, with and without disabilities such as cerebral palsy. The test is comprised of six test conditions. This test will be administered only in a subsample of participants (30 with PWS and 55 with non-syndromal obesity).
Physical activity self-efficacy Baseline to 24 weeks Self-efficacy for physical activity will be measured with an eight item questionnaire rated on a five point scale ranging from disagree a lot to agree a lot . This questionnaire was originally developed for use with children in fifth grade, but also validated with children in eighth grade. This questionnaire had a test-retest reliability of r= 0.84 over a period of two weeks. Additionally, the questionnaire had an internal consistency score of 0.88. Dishman, R.K., et al.
