“…Lanerolle-Dias et al (2011), observaron que los valores en población adolescente de Sri Lanka, son muy similares a la encontrada en población china. Igualmente estudios realizados en población infantil de la etnia aymará de Arica (Espinoza-Navarro, et al, 2009) determinaron que los índices de masa corporal en esta etnia son significativamente menores con respecto a la población infantil no aymará.…”

RESUMEN:La obesidad se caracteriza por un aumento excesivo de la grasa corporal. En Chile, en el año 2010, se determinó que el 25,1% de la población sobre los 15 años, presentaba obesidad y un 39,3 % sobrepeso. El objetivo de esta investigación fue validar un método económico y de fácil manejo para los profesionales de la Educación, que permita determinar los porcentajes de masa grasa (%MG) en población escolar, ocupando las variables de perímetros corporales, el peso y la talla (PPT). A una muestra de 1725 alumnos de enseñanza básica, 1020 niñas y 705 niños, de entre 10 a 14 años de edad de la Comuna de Arica (XV Región), se les determinó el %MG según el modelo propuesto de perímetro, peso y talla (PPT). Como modelos de referencia se utilizaron los protocolos de Durnin & Womersley (1974) y el protocolo de Slaughter et al. (1988). Los resultados muestran que los índices de masa corporal (IMC), presentan valores normales de 21 kg/m 2 tanto para niñas como niños. La sumatoria de los pliegues corporales de bíceps, tríceps, subescapular, ilíaco y abdominal (S5), es significativamente mayor en la población femenina, respecto a los varones (108,5 mm y 81,4 mm respectivamente). La comparación del porcentaje de masa grasa, entre los diversos modelos en estudio demuestra que el modelo propuesto de PPT, no presenta diferencias significativas (NS). Todos ellos expresan valores sobre el 20% en la población en estudio, propio de sobrepeso y obesidad. Se concluye que el modelo de perímetros, peso y talla, es eficaz para determinar los porcentajes de masa grasa en población escolar. La población en estudio presenta altos índices de masa grasa.

“…Fourier transform infrared (FTIR) spectroscopy has previously been shown to be a robust estimation method of detection of deuterium in saliva. Hence, deuterium dilution determined by FTIR can be used in validation of SFT equations for prediction of %FM [ 13 ].…”

BackgroundValid skinfold thickness (SFT) equations for the prediction of body fat are currently unavailable for South Asian women and would be a potentially robust field tool. Our aim was to assess the validity of existing SFT equations against deuterium (2H2O) dilution and, if invalid, to develop and validate an SFT equation for % fat mass (%FM) in Sri Lankan women.MethodsH2O dilution was used with Fourier transform infrared (FTIR) spectroscopy as the criterion method for the assessment of %FM in urban Sri Lankan women (30–45 years). This data was used to assess the validity of available SFT equations and to generate and validate a new SFT equation for the prediction of %FM against the criterion method. Women (n = 164) were divided into validation and cross-validation groups for the development and validation of the new equation. The level of agreement between the %FM calculated by the final derived prediction equation and the %FM obtained by 2H2O dilution was assessed using Pearson’s correlation coefficient (R) and Bland Altman plots. Student’s t test was used to assess over- or underestimation, and significance was set at p < 0.05.ResultsExisting equations significantly (p < 0.001) underestimated %FM compared with the 2H2O dilution method. The final equation obtained was %FM = 19.621 + (0.237*weight) + (0.259*triceps). When compared with 2H2O dilution, %FM by the equation was not significantly different. There was a significant (p < 0.001) correlation between %FM by the reference method and %FM by the equation. The limit of agreement by Bland Altman plot was narrow with a small mean positive bias.ConclusionsExisting SFT equations were not applicable to this population. The new equation derived was valid. We report a new SFT equation to predict %FM in women of South Asian ancestry suitable for field use.

“…The triceps and supra-iliac skin fold thickness required for the equation was measured in triplicate on the left side of the body, in accordance with standard protocols [12], using a Harpenden caliper (gradation 0.2 mm, range: 80 mm, Seca, HSK-BI), to the nearest 1 mm. The average of three SFT recordings was used in the analysis.…”

Background: Urbanisation has been reported to have negative effects on lifestyle and possibly on body composition. The aim of this study was to assess the effect of urbanization on dietary patterns and measures of body composition in Sri Lankan adolescent girls. Methods: Body Mass Index was calculated in 552 adolescent school dropouts. Percentage body fat was calculated using a population specific skin fold thickness equation. Dietary patterns were identified based on information obtained from a food frequency questionnaire. Extraction of factors of the dietary patterns was by principal component analysis. The sum of hours / week spent on physical activity was calculated. Focus group discussions were held to gather supportive qualitative data on food related behaviors. Multivariate linear regression models were used to assess the association between independent variables and dietary patterns. Results: Two dietary patterns were identified; a convenience-based dietary pattern with higher factor loadings for starchy foods other than rice, animal foods, dairy products, fruits, sweetened food and fried food, and a traditional pattern with higher factor loadings for rice, tubers and potatoes, vegetables and dark green leafy vegetables. An urban girl had greater than three times the risk of having a higher percentage body-fat than a rural girl (P = 0.01, OR = 3.2). Time spent on physical activity was significantly (P = 0.003) higher among the rural girls. Focus group discussions indicate that urban girls preferred food from vendors due to convenience while rural girls preferred home cooked meals. Conclusions: Urban adolescents in this study followed a convenience based dietary pattern and this dietary pattern and lower physical activity was associated with overweight and higher body fat.
