This review summarizes the association between directly assessed physical activity and adiposity in preschool children (age 1.5-6 years). It includes 17 cross-sectional and longitudinal studies that were published between January 1999 and February 2010. The association between physical activity and obesity seems to depend on the outcome measure of adiposity. In 60% (3/5) of the studies using percentage body fat, an inverse significant relationship with physical activity was found against 18% (2/11) of the studies that used body mass index as method to assess adiposity. Physical activity is inversely related to percentage body fat in preschool children. The associations between physical activity and body mass index as a measure of adiposity in preschool children remain elusive. Further studies using directly measured physical activity and percentage body fat to define adiposity are needed to draw more firm conclusions.

    • "Despite these limitations, Must and Tyboor concluded that research generally supports a significant longitudinal relation between physical activity and weight in middle childhood and adolescence. Our examination of studies not included in this review suggests that this evidence is less clear for younger children, as results are mixed and methodological shortcomings are more common[35,36].The second review was conducted by Reichert, Menezes, Well, Dumith, and Hallal[37]. They examined 24 studies of the relation between physical activity and adiposity in adolescents. "

    • "Numerous validation studies have been performed to justify the use of particular cut-offs in this population, but no consensus has been reached regarding which cut-offs are the most appropriate for studies of pre-school-aged children (Bornstein et al., 2011). Third, our sample was comprised of Japanese children, setting it apart from the previous studies that examined Caucasian, African-American and Hispanic pre-schoolers (Sijtsma et al., 2011). The relationship between PA and environmental factors in Japan may be different than those in other countries. "

    ABSTRACT: Abstract Background: The prevalence of thinness has increased among Japanese children. Aim: The purpose of this study was to examine the association between physical activity and body mass index (BMI) among Japanese pre-school children. Subjects and methods: Subjects were 425 4-6-year-old Japanese girls and boys. Their weights were classified as normal, overweight or thin, based on Cole's international cut-offs for BMI. Physical activity was assessed using a triaxial accelerometer (ActivTracer, GMS) for 6 consecutive days. Results: Physical activity in overweight children was comparable to that in normal-weight children after controlling for age and gender. However, thin children spent significantly greater time engaged in low-intensity activities (physical activity ratio < 2) and spent less time engaged in light-intensity physical activity (2 ≤ physical activity ratio < 3) and moderate-to-vigorous physical activity (physical activity ratio ≥ 3) than normal-weight and overweight children, and less time engaged in higher-intensity physical activity (physical activity ratio ≥ 4) than normal-weight children. Moreover, thin children spent significantly less time engaged in locomotive physical activity than normal-weight or overweight children. Conclusion: This study suggests that thinness, rather than excess weight, is associated with decreased light, moderate and high intensity physical activity in Japanese pre-school children.

    ABSTRACT: OBJECTIVE To assess the effects of a multidisciplinary intervention program for 3-year-old to 5-year-old overweight and obese children compared with a usual-care program. DESIGN Randomized controlled clinical trial conducted from October 2006 to March 2008. SETTING Groningen Expert Center for Kids with Obesity at Beatrix Children's Hospital, University Medical Center Groningen. PARTICIPANTS Seventy-five children (29 overweight, 46 obese) aged 3 to 5 years. INTERVENTION A multidisciplinary intervention program vs a usual-care program. Anthropometry was performed and body composition was determined by bioelectrical impedance analysis and ultrasonography at the start and end of the 16-week program and 12 months after starting the intervention. MAIN OUTCOME MEASURES The actual weight reduction, change in body mass index (BMI, calculated as weight in kilograms divided by height in meters squared), BMI z score, body fat percentage, and visceral fat in the multidisciplinary intervention group compared with a usual-care group. RESULTS At the end of the treatment program, children in the multidisciplinary intervention group showed a greater decrease in BMI, BMI z score, and waist circumference z score compared with children in the usual-care group. At 12 months, children in the intervention group showed greater decreases in BMI, BMI z score, waist circumference, and waist circumference z score compared with children in the usual-care group. Visceral fat showed a trend toward a higher decrease. CONCLUSIONS A multidisciplinary intervention program in 3-year-old to 5-year-old overweight and obese children had beneficial effects on anthropometry and body composition. The positive effects were still present 12 months after the start of the intervention. TRIAL REGISTRATION Identifier: ISRCTN47185691.
