Introduction: Body mass index (BMI) provides little information on body composition. For example, two people with the same BMI might have different compositions. In this sense, development of a new able to provide composition is clinical and scientific interest. The aim study was suggest modified formula.Material methods: A total 108 subject, females 56 males 52, 0-73 years old, in various phys...

The aim of this study was to estimate the association between birth order and number of siblings with body composition in adolescents. Data are from a birth cohort study conducted in Pelotas, Brazil. At the age of 18 years, 4563 adolescents were located, of whom 4106 were interviewed (follow-up rate 81.3 %). Of these, 3974 had complete data and were thus included in our analysis. The variables ...

General considerations in assessing body composition in children and youths are described. Various methods are explored and recommendations are made for methods to be used in the International Growth Standard for Preadolescent and Adolescent Children Project. Exclusion of under- and overweight participants is recommended, and a method is proposed to assess both underweight and overweight. In ad...

Background and Objectives: Breast milk composition is affected by several factors such as maternal diet and body mass index. Milk fats include a major calorie content of the milk, which changes dramatically throughout the lactation. The aim of the present study was to assess breast milk fatty acid profile in overweight and obese mothers and its correlations with maternal body mass index. Mater...

BACKGROUND Physical activity (PA) is suggested to contribute to fat loss not only through increasing energy expenditure "per se" but also increasing muscle mass; therefore, it would be interesting to better understand the specific associations of PA with the different body's components such as fat mass and muscle mass. The aim of the present study was to examine the association between objectiv...

UNLABELLED The body mass index (BMI) is used to assess nutritional status. The result in athletes may be overestimated due to increase in muscle mass. OBJECTIVE To assess the usefulness of fat mass index (FMI) and lean mass index (LMI) determination as indicators of nutritional status and to compare the results with BMI. MATERIAL AND METHODS We studied 28 amateur rugby players, male. After ...

BACKGROUND Dual-energy X-ray absorptiometry (DXA) provides separate measurements of fat mass, fat-free mass and bone mass, and is a quick, accurate, and safe technique, yet one that is not readily available in routine clinical practice. Consequently, we aimed to develop statistical formulas to predict fat mass (%) and fat mass index (FMI) with simple parameters (age, sex, weight and height). ...

Decreased physical performance due to loss of muscle mass (i.e. sarcopenia) is prevalent in ageing and appears more pronounced in chronic disease. A comprehensive profile of the sarcopenic phenotype in chronic obstructive pulmonary disease (COPD) is not yet available. The aim of the present study was to characterise prevalence, functional implications and predictive value of sarcopenia with or ...
