Physically active lifestyle and good cardiorespiratory fitness have been associated with good arterial health in adults. However, there is limited evidence available among children. The aim of this master\u2019s thesis was to investigate the associations of physical activity at different intensity levels, sedentary time and cardiorespiratory fitness with arterial stiffness and arterial dilation capacity in 9\u201311 years old children during two-year follow-up. \n\nThe thesis is based on baseline (2007\u20132009) and 2-year follow-up data of the Physical Activity and Nutrition in Children (PANIC) -study conducted in University of Eastern Finland. In total of 245 children (girls 51,8%) was studied. Light, moderate and vigorous physical activity and sedentary time (min/d) were assessed by using combined acceleration and heart rate monitor. Cardiorespiratory fitness (maximal workload) was assessed by maximal cycle ergometer exercise test and scaled by lean body mass (LM). Arterial stiffness (SI) and arterial dilation capacity in response to a bout of exercise (\u2206RI) were assessed by pulse contour analysis (PCA). Statistical analyses were conducted by using linear regression models. \n\nThe results indicated that during 2-year follow-up, a change in vigorous physical activity (\u2206VPA) was positively associated with arterial dilation capacity (\u2206RI) after adjustment for age and sex (p=0,031). Further adjustments (baseline VPA, adiposity, systolic blood pressure, study group) had no effect on the association (p=0,026). The independent association was found only in boys (p=0,028) when the analysis was conducted separately between sexes and the effect of maturity was considered. There were no associations observed between other variables and \u2206RI or between any variables and arterial stiffness (SI). \n\nIncrease in vigorous physical activity was the only predictor of better arterial health among 9\u221211 years old children during 2-year follow-up. The association was stronger in boys and was observed in arterial dilation capacity but not in arterial stiffness. According to these results vigorous physical activity may be important in maintaining normal arterial function in pre-pubertal children, especially among boys. The results support the role of vigorous physical activity in early prevention of arterial diseases.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-11-04T09:37:09Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-11-04T09:37:09Z (GMT).
