“…The results for aerobic fitness support some 34,35 but not all 36,37 previous work. From prior studies, the relationship between aerobic fitness and CVD risk factors is strongly mediated by body fatness.…”

PURPOSE:The purpose of this study was to examine the association of body mass index (BMI) and aerobic fitness on cardiovascular disease (CVD) risk factors in adolescents. METHODS: The sample included 416 boys and 345 girls 9-18 y of age from the Québec Family Study. Participants were crosstabulated into four groups using a median split of age-adjusted physical working capacity (PWC) and body mass index (BMI). Group differences in age-adjusted CVD risk factors (blood pressures, fasting total cholesterol (CHOL), LDL -C, HDL-C, HDL/ CHOL, triglycerides, glucose, and a composite risk factor score) were examined by two-way ANOVA. RESULTS: Several CVD risk factors showed significant main effects for PWC, BMI and/or the PWC by BMI interaction. In general, low fit males and females had higher blood lipids and glucose compared to their high fit counterparts within BMI categories although none of the differences reached statistical significance. The high fit/low BMI group showed the best CVD risk factor profile while the low fit/high BMI showed a poorer profile as evidenced by several significant differences between these two groups. Other significant differences occurred for various risk factors between groups. CONCLUSION: Both aerobic fitness and BMI show an independent association with CVD risk factors in adolescents.

“…The impact on health may thus be similar in both groups. The findings, especially among the coastal students, are in accordance with other reports (Tell & Vellar, 1988;Oygard et al, 1995;Boreham et al, 1999).…”

Blood lipids, fatty acids, diet and lifestyle parameters in adolescents from a region in northern Norway with a high mortality from coronary heart disease

Introduction: Students aged 13 and 14 y, in a region in northern Norway with high blood cholesterol levels and high mortality from coronary heart disease (CHD) in the adult population, were studied with respect to lifestyle, dietary habits, nutritional intake and blood lipids including fatty acids in serum. The students came from a coastal community with seawater fish as an important part of the traditional diet, and an inland community with meat from reindeer as a major constituent of the diet. Objective: To investigate whether the traditional diet was maintained among the adolescents and to evaluate the lifestyle and blood lipids. The study was followed up after 1 y. Results: The adolescents from the coastal region did not maintain the traditional diet. In the inland region the students had a high intake of meat, probably reflecting the traditional food culture. The inland boys had higher mean body mass index (BMI) than the coastal boys, and 12% had BMI>28, as compared to none of the coastal boys. Other findings showed that the students had higher levels of blood cholesterol than in the south of Norway and several other countries (about 25% had total cholesterol >5.2 mmol=l), higher intake of dietary sugar and fat than the national recommendations and little intake of seawater fish with corresponding low levels of n-3 fatty acids. This did not change after 1 y of follow up. Some 10 -20% reported daily smoking and 8 -13% reported that they rarely or never did physical exercise. About 30% of the students presented no factors negatively related to development of cardiovascular disease.Conclusion: The findings demonstrate, in the majority of students at the age of 13 and 14 y, the appearance of factors contributing to development of cardiovascular disease (CHD).

“…Although some cross-sectional studies in adolescents have found an inverse relationship between physical activity and BMI or skinfold measurements (Tell et al 1988;Macek et al 1989;Kemper et al 1990), other studies could not confirm the association (Andersen et al 1989;Marti & Vartiainen, 1989;Sallis et al 1989). Two large crosssectional studies, which reported data on both activity and diet, noted only a weak association between lower levels of activity and higher levels of adiposity (Sunnegardh et al 1986;Shannon et al 1995), but in both studies confounding variables could not be fully excluded.…”

How active are we? Levels of routine physical activity in children and adults

The accurate measurement of physical activity is fraught with problems in adults, but more especially in children because they have more complex and multi-dimensional activity patterns. In addition, the results of different studies are often difficult to interpret and compare, because of the diversity of methodological approaches, differences in data analysis and reporting, and the adoption of varying definitions of what constitutes an appropriate level of activity. Furthermore, inactivity is seldom quantified directly. Although there exists an extensive literature documenting the health benefits of regular physical activity in adults, activity-health relationships in children are not clear-cut. Current recommendations reinforce the concept of health-related activity, accumulating 30 min moderate-intensity exercise on at least 5 d/week (adults) and 1 h moderate-intensity exercise/d (children). Evidence suggests a high prevalence of inactivity in adults, but whether or not inactivity is increasing cannot be assessed currently. Similarly, no definite conclusions are justified about either the levels of physical activity of children, or whether these are sufficient to maintain and promote health. Data to support the belief that activity levels in childhood track into adulthood are weak. Inactivity is associated with an increased risk of weight gain and obesity, but causality remains to be established. In children there is strong evidence to demonstrate a dose-response relationship between the prevalence and incidence of obesity and time spent viewing television. Future research should focus on refining methodology for physical activity assessment to make it more sensitive to the different dimensions and contexts of activity in different age-groups.
