Selected AbstractsOriginal Article: Activity, inactivity and quality of life among Lebanese adolescentsPEDIATRICS INTERNATIONAL, Issue 4 2010Abdallah Fazah Abstract Background:, The aim of the present study was to investigate recent overweight and obesity prevalence rates for Lebanese adolescents, and to examine differences in physical activity, screen time (sum of time spent in front of TV, computer, and videogames), and health-related quality of life (HRQOL) for the first time among normal, overweight, and obese adolescents. Methods:, One thousand Lebanese adolescents (14,18 years old) from nine schools participated in the study. Height, weight, physical activity, screen time, and HRQOL variables were assessed using validated self-report questionnaires. Results:, A total of 7.8% of boys and 1.75% of girls were obese, and 22.5% of boys and 12.47% of girls were overweight. Normal-weight boys reported higher physical activity scores at health clubs than obese boys. Normal-weight girls reported higher leisure time and total physical activity scores than obese girls. In the normal-weight group, boys reported higher total screen time than girls. Normal-weight boys reported higher physical functioning scores than their obese peers. Normal-weight girls reported higher physical functioning and average HRQOL scores than obese girls. Normal-weight and overweight boys reported higher average HRQOL scores than girls. Conclusion:, The present study is the first to provide data on physical activity, screen time, and HRQOL among Lebanese adolescents. Despite the need for further research, all those concerned with the pediatric population are urged to develop and implement effective strategies to increase physical activity and improve HRQOL among adolescents based on the present findings.

Additionally, we analysed the interaction between baseline fitness level and changes in fitness. Methods:, This is a 3-year longitudinal study of 345 high school students aged 11,19 years. Students performed curl-ups, push-ups and 20-m shuttle run tests from Fitnessgram. PA and ST were evaluated using a standard questionnaire. Standardized scores of fitness tests were summed. Changes over time were calculated as ,1 (2007 minus 2006), ,2 (2008 minus 2007) and ,3 (2008 minus 2006). Results:, Changes in PAI were positively and independently associated with changes in fitness in ,1, ,2 and ,3. Changes in BMI were negatively associated with changes in fitness in ,3. Participants highly fit at baseline were those who showed positive changes in PAI over ,3, decreased changes in ST and had the lowest increase in BMI over 3 years compared with those low-fit at baseline. Conclusions:, Changes in BMI were associated with changes in fitness over 3 years. However, changes in PAI were the best predictor for changes in fitness in each year and over the 3 years of evaluation in youth.

Methods: A cohort of 122 girls and 146 boys (age at entry 10 years) from three rural states in the western USA was studied over an 18-month period. Subjects were measured for height and weight. Habitual physical activity, screen time (television viewing, video games and computer use) and dietary variables were assessed by a questionnaire. Cross-sectional and longitudinal analyses were conducted to examine the associations between physical activity, screen time and diet with BMI at baseline and follow-up and change in BMI. Results: At baseline, approximately 10% of boys and girls were obese and 17.8% of boys and 14.8% of girls were overweight. BMI showed a high degree of stability for boys and girls (r = 0.90), whereas physical activity, screen time and dietary habits showed moderate stability (r = 0.31,0.50) across the 18-month period. Cross-sectional and longitudinal correlations between physical activity, screen time, diet and BMI were low and non-significant (r < 0.15). The regression models explained between 8% and 22% of the variance in the change in BMI; however, none of the predictor variables were statistically significant. Conclusion: Physical activity, screen time and dietary habits were not significantly related to the BMI in cross-sectional or longitudinal analyses. Further research is warranted to better understand the complex, multifactorial phenotype of the BMI in growing and maturing children. [source] | ||||||||||
