ABSTRACT 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.

    ABSTRACT: High amounts of time spent sedentary and low levels of physical activity have been implicated in the process of excessive adiposity gains in youth. The aim of this review is to discuss the role of physical activity, sedentary time and behaviour (i.e. television (TV)-viewing) in relation to adiposity during the first two decades of life with a specific focus on whether the association between sedentary time, and behaviour and adiposity is independent of physical activity. We identified nine cohort studies (three prospective) whether sedentary time was associated with adiposity independent of physical activity. Eight of these studies suggested that sedentary time was unrelated to adiposity when physical activity was taken into account. Results from studies (n 8) examining the independent association between TV-viewing and adiposity independent of physical activity were mixed. Those that observed a positive association between TV-viewing and adiposity independent of physical activity discussed that the association may be due to residual confounding. A few additional studies have also challenged the general notion that low levels of physical activity leads to fatness and suggested that higher baseline fatness may be predictive of a decline in physical activity. It appears unlikely that higher levels of sedentary time are associated with or predictive of, higher levels of adiposity when physical activity is controlled for in youth. Specific sedentary behaviours such as TV-viewing may be associated with adiposity independent of physical activity but the results may be explained by residual confounding.

    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: BACKGROUND: Movement by an infant during the first year of life might influence its activity level and thereby influence growth in early childhood. AIM: To examine whether the time that an infant is able to move unrestrictedly and time spent in baby seats are related to weight and waist circumference at age 9months and growth from 9 to 24months. METHODS: In the GECKO Drenthe birth cohort, weight and height were measured in Well Baby Clinics at the ages of 9 and 24months. Time spent moving unrestrictedly and time spent in baby seats were reported on a questionnaire at age 9months. Children born <37weeks or with a low birthweight (<2500g) were excluded. Outcomes were defined as the Z-scores for weight-for-height, weight-for-age, and waist circumference-for-age at the ages of 9 and 24months, and changes in Z-scores as between 9 and 24months of age. RESULTS: The time an infant is able to move unrestrictedly at age 9months was inversely related to Z-score waist circumference at 9months, and the change in Z-scores weight-for-height and weight-for-age between the ages 9 and 24months. For time spent in baby seats, 'never users' showed a decline in Z-score weight-for-height as compared to those who used baby seats. On the contrary, Z-score waist circumference-for-age declined in children sitting for 1h or more in baby seats. CONCLUSION: More time spent moving unrestrictedly in infancy may contribute to a healthy growth pattern.
