Body fat assessment in XXXX Lankan adolescent @entity1 ; development of a simple field tool.

@entity1 @entity3595 @entity28 @entity272
BACKGROUND: Development of accurate, simple measures of body fat is essential in developing countries due to the rising prevalence of overweight and @entity28 . Application of @entity272 ( @entity272 ) to body fat prediction equations is an inexpensive method suitable for field settings. AIM: To determine percentage fat mass (%FM) of @entity3595 Lankan adolescent @entity1 using Fourier Transform Infrared spectrometry (FTIR) as a reference method and develop a @entity272 -prediction equation to estimate %FM. METHODS: Weight, height and @entity272 were measured and %FM determined by FTIR in 131 adolescent, post-menarcheal @entity1 (15-19 years). @entity272 were applied to available body composition equations for validation in the population. A new equation for %FM was derived and validated. RESULTS: Mean %FM (FTIR) was 19.13    8.2.Selected body composition prediction equations over-estimated %FM. The multiple regression procedure yielded a final equation consisting of two anthropometric and one demographic variable, % FM = 9.701 - (0.460)* age+(0.640)*TricepsSFT+(0.583)*Supra-iliacSFT. CONCLUSIONS: Existing @entity272 prediction-equations are unsuitable for predicting %FM in this population. The new equation utilizing one peripheral and one truncal skin-fold, is appropriate for prediction of %FM in this population and may be applicable to other South Asian/Asian-Indian adolescents following validation.
