![]() ![]() Screening for obesity in children and adolescents: US Preventive Services Task Force recommendation statement. TMI is stable in adolescents, and could be a more efficient indicator for screening obesity-related cardio-metabolic risks in routine health screening compared with BMI.įorce USPST, Barton M. Tri-ponderal mass index (TMI) performed superior to BMI z scores and similar to BMI percentiles in Chinese and American participants. Combined use of weight/height 3 and waist-to-height ratio did not change the classification accuracy. Results were similar in American participants. ![]() When 85th and 95th percentiles were set as thresholds for each sex, weight/height 3 showed similar accuracy to BMI percentiles, and were more precise than BMI z scores. Weight/height 3 is relatively stable during childhood in both populations. Misclassification rates of each index were calculated. Log-binomial regression models and areas under receiver-operating characteristic curves were used to examine their abilities on identifying cardio-metabolic risks, including elevated blood pressure, impaired fasting glucose, and dyslipidemia. ![]() Analyses and comparisons of BMI, weight/height 2.5, and weight/height 3 were predominantly discussed, while BMI z score, converted by BMI based on 2007 WHO growth standard, was set as the reference. Methodsĥ7,201 Chinese children aged 7–18 and 10,441 American children aged 12–18 with complete record of sex, age, height, weight, and waist circumference were included. #Eas daily fitness assessment cardio pdf trialAn adequately powered randomized controlled trial should be performed to further evaluate this hypothesis.To investigate the performance of weight/height n in discriminating obesity-related cardio-metabolic risks, and compare their performance with BMI in Chinese and American children. The trend for superior cognitive scores in the moderate-fitness compared to the low-fitness groups was unequivocal, both in terms of accuracy and reaction time.Ĭonclusion: Maintenance of higher levels of cardiovascular fitness may help protect against cognitive deterioration, even at an advanced age. Results: The moderately-fit group achieved significantly better scores on the global cognitive score (U = 97, p = 0.04), and a significant correlation was found between peak VO 2 and attention, executive function, and global cognitive score (r s =. Cognitive function was assessed by means of a computerized neuropsychological battery. Based on a median score of peak VO 2, participants were divided into low-fitness and moderately-fit groups. Methods: Thirty-eight individuals, aged 65.3 to 85.3 years, performed a graded, progressive, maximal exercise test. This study was thus designed to examine the relationship between physical fitness and function in multiple cognitive domains in subjects older than those previously reported. In addition, in spite of the significant increase in life expectancy, the age of participants in these studies does not extend beyond a mean age of 70 years. Background: Studies generally describe the relationship between physical fitness and cognitive function by measuring only one or two specific cognitive tasks. ![]()
