ABSTRACT BMI has been recommended for evaluating overweight and obesity in children and adolescents in the clinical setting. Definitions of overweight and obesity are based on percentile cutoff points. There are both strengths and limitations of BMI for this use. The strengths include the fact that BMI is cheap and relatively easy to use. The weaknesses include the fact that BMI percentiles are not widely used, and categorization of BMI percentiles may not adequately define risk of comorbid conditions. In addition, percentiles are not optimal for stratifying children and adolescents with very high BMI. Alternatives to the use of BMI and BMI percentiles include waist circumference to evaluate regional fat deposition and replacement of percentiles with z scores. Despite limitations, BMI and BMI percentiles have great utility in the clinical setting and the potential to be even more useful as BMI is used more frequently and more appropriately by primary care providers. Additional research on alternatives or adjuncts to BMI is needed.

    ABSTRACT: Introduction School-based health centers (SBHCs) serve many overweight/obese children, yet little is known about provider adherence to obesity guidelines. The purpose of this descriptive study was to evaluate obesity care assessment practices of SBHC providers prior to completing training on obesity guidelines. Method Providers (n = 33) from SBHCs in six states (AZ, CO, NM, MI, NY, and NC) completed The International Life Science Institute Research Foundation Assessment of Overweight in Children and Adolescents Survey. Results Most providers reported using body mass index percentile (93.9%) to assess weight. In caring for overweight/obese children, providers reported screening for hypertension 100% of the time and cardiovascular disease 93.9% of the time, and approximately two thirds reported requesting total cholesterol and lipid profile laboratory assessments. Some assessment guidelines were not routinely followed. Discussion SBHCs serve a high-risk population, and providers in this study may benefit from additional training on assessment guidelines and quality improvement processes to improve adherence to current guidelines.

    ABSTRACT: Aim: to analyze the secular changes in body size and composition of two cohorts of children from La Plata City, Argentina, with a 35-year follow-up. Subjects and methods: Cohort 1 (C1) was measured in 1969–1970 and included 1772 children (889 boys, 883 girls), and Cohort 2 (C2), measured in 2004–2005, included 1059 children (542 boys, 517 girls). Both cohorts were obtained from matching geographical areas and comprised children from 4 to 12 years. Body weight (W); Height (H); Upper arm circumference (UAC); Tricipital (TS) and Subscapular skinfolds (SS) were measured, and Body Mass Index (BMI) and muscle (UMA) and fat (AFA) brachial areas were calculated. Prevalence of overweight and obesity was estimated by IOTF. To compare C1-C2 we used a generalized linear model with log-transformed variables, and chi square test. Results: There were significant and positive differences between C2-C1 in W, UAC, SS, TS, and AFA. In contrast, H was not significantly different and UMA was significantly different but with negative values. The prevalence of over-weight and obesity was 14.5 % and 3.8 % in C1, and 17.0 % and 6.8 % in C2. Differences between cohorts were significant for obesity. Conclusion: The shifts observed for soft tissues – positive trend for fat and negative for muscle area – occurring without changes in height lead us to suppose that in these three decades, La Plata's population has experienced deterioration in living conditions and important changes in their lifestyle, such as an increased consumption of energy-dense foods and sedentary habits.

    ABSTRACT: Obez adolesanlarda vücut yağı ölçüm yöntemlerinin etkinliği Hayri Baran YOSMAOĞLU, Gül BALTACI, Orhan DERMAN [Yosmaoğlu HB, Baltacı G, Derman O. Obez adolesanlarda vücut yağı ölçüm yöntemlerinin etkinliği. Fizyoter Rehabil. 2010;21(3):125-131. Effectiveness of body fat measurement methods in obese adolescents.] Research Article Amaç: Bu çalışmanın amacı basit antropometrik ölçümleri objektif vücut yağı ölçüm sonuçları ile karşılaştırıp, etkinliği yüksek yöntemleri belirlemek; böylece obeziteyi en erken ve doğru bir şekilde belirlemeye katkı sağlamaktı. Gereç ve yöntem: Seksen sekiz obez adolesanın vücut yağ kütlesi biyoelektrik empedans analizi ile ölçüldü. Vücut yağ kütlesinin dağılımını belirlemek için bel çevresi, kalça çevresi ve deri kıvrım kalınlığı ölçümleri yapıldı. Bu ölçümler arasındaki ilişkiyi ortaya çıkarmak için korelasyon analizi yapıldı. Sonuçlar: Kız çocuklarında; vücut yağ kütlesi sonuçları ile triceps, abdominal ve suprailiak deri kıvrım kalınlığı ölçümleri arasında orta düzeyde pozitif korelasyon bulundu (sırasıyla r=0.56, 0.52, 0.62; p<0.01). Vücut yağ kütlesi ile vücut kütle indeksi (kg/m²) (VKİ), bel çevresi ve kalça çevresi arasında yüksek düzeyde pozitif korelasyon vardı (sırasıyla r=0.89, 0.82, 0.85; p<0.01). Erkek çocuklarında ise; vücut yağ kütlesi ile subskapular deri kıvrım kalınlığı ve pektoral deri kıvrım kalınlığı arasında orta düzeyde pozitif korelasyon vardı (sırasıyla r=0.67, 0.43; p<0.01). Aynı zamanda triceps deri kıvrım kalınlığı, bel çevresi ölçümü, kalça çevre ölçümü, VKİ ile vücut yağ kütlesi arasında yüksek düzeyde pozitif korelasyon bulundu (sırasıyla r=0.75, 0.86, 0.89, 0.96; p<0.01). Her iki cinsiyette bel-kalça oranı ile vücut yağ kütlesi arasında bulunan düşük düzeyde pozitif korelasyon istatistiksel olarak anlamlı değildi (kızlar için r=0.18, erkekler için 0.13; p>0.05). Tartışma: Bu çalışmanın sonuçları bel çevresi ve kalça çevresi ölçümleri ile vücut yağ kütlesi arasında yüksek düzeyde korelasyon olduğunu gösterdi. Deri kıvrım kalınlığı ölçümlerinin ise, vücut yağ kütlesi ile korelasyonu daha düşük bulundu. Bel ve kalça çevre ölçümleri, vücut yağ kütlesini daha doğru şekilde göstermesi nedeniyle, adolesanlarda obezitenin belirlenmesi için kullanılabilecek etkili yöntemler olarak önerilebilir. Anahtar kelimeler: Adolesan, Obezite, Vücut yağ dağılımı, Deri kıvrım kalınlığı. Effectiveness of body fat measurement methods in obese adolescents Purpose: The aim of this study was to compare simple anthropometric measurements with objective body fat measurement outcomes and to determine the methods which had high effectiveness thus to make a contribution to the easy and effective diagnosis of the obesity. Materials and methods: Body fat mass of 88 obese adolescents was measured by bioelectric impedance analysis. Skinfold thickness, waist and hip circumferences were measured to determine the distribution of body fat. Correlation analysis was performed to investigate the relationship among these measurements. Results: A modest positive correlation was found between fat mass and triceps, abdominal, suprailiac skinfold thickness in girls (r=0.56, 0.52, 0.62; p<0.01, respectively). There was a strong positive correlation between body fat mass and body mass index (BMI), waist, hip circumference (r=0.89, 0.82, 0.85; p<0.01, respectively). In boys, there was a modest positive correlation between fat mass and subscapular, pectoral skinfold thickness (r=0.67, 0.43; p<0.01, respectively). Strong positive correlation was also found between fat mass and triceps skinfold thickness, waist, hip circumference, BMI (r=0.75, 0.86, 0.89, 0.96, p<0.01). Weak positive correlation between waist to hip ratio and fat mass was not statistically significant in both genders (girls: r=0.18, boys: r=0.13; p>0.05). Conclusion: The result of these study indicated that there was a strong correlation between body fat mass and waist, hip circumference. The skinfold thickness correlated less with body fat mass. Therefore, waist and hip circumferences which show body fat more accurately could be suggested as an effective method to measure obesity in adolescents. Key words: Adolescent, Obesity, Body fat distribution, Skinfold thickness.
