Purpose: Cystic fibrosis (CF) is a genetic, metabolic disease. Long-term therapy often leads to inappropriate calcification of bones. Dual X-ray absorptiometry (DXA) is considered a „gold-standard” for bone mineral density (BMD) assessment, but high usage costs can limit its availability. This paper compares two methods for BMD assessment in CF patients: hand radiograms method and densitometry using DXA method. Materials and methods: The study was performed in a group of 26 CF patients (10F, 16M), aged 7-30 years. In all cases, DXA measurements were performed, along with bone mass assessment using DENSY2004 system for digital assessment of hand radiograms. Stepwise binary logistic regression was used to examine the contribution of bone age, BMI, Cole's index and hand radiograms parameters to low BMD expressed as Z-score ≤-1SD. Results: Statistical analysis of the gathered data revealed that hand radiograms method allow for estimation of Z-score below -1SD with accuracy of 84.62% comparing to DXA. Sensitivity and specificity of this estimation in the studied group of CF patients was 86.67% and 81.82%. Conclusions: Hand radiograms method has good accuracy, sensitivity and specificity; therefore, it can be an alternative for DXA in BMD assessment. It can be implemented in chronic diseases affecting BMD like cystic fibrosis.

Falls may occur in each ontogenesis phase, but they become more frequent in the elderly and lead to serious health consequences. Dynamic changes in senior citizens’ environment and lifestyle makes studies of risk for falls necessary. To determine the relationship between the risk for falls and the objective functional and structural examination in the elderly living in Poland. The research consisted of 196 females and 61 males aged 60-88 recruited from health clinics, senior citizen centers and Universities of the Third Age between 2009-2012. Following parameters were collected: functional physical tests “30 second Chair Stand Test” and Timed Up and Go Test”, the flexor muscles and knee extensors force, the bone mineral density was measured in distal radius of the forearm with the EXA - 3000, the total risk for fall assessed by 5 tests by abbreviated version of Fallscreen test. Multiple linear regression and linear correlation were used for assessment of relationship with total estimated risk for fall and other parameters. The subjects displayed significant dimorphic differences within the range of the functional parameters and bone mineral density to the advantage of males. Only in women results revealed a significant link between the risk for falls and the dynamic balance, as well as the maximum quadricep muscle force equal. Strength of the lower limb muscles seems to be critical for decreasing the risk for fall. Special programs for strengthening this part of the body for older people should be elaborate.

Objectives: The objective of this study was to assess the relation between body composition and body mass index (BMI) to bone mineral density (BMD) in college American football players. Methods: A total of 90 players (22.44 + 1.71 years old) from the major college football league in Mexico participated. The dual-energy X-ray absorptiometry (DEXA) equipment was used, in which the values of BMI, fat mass, lean mass, total mass and BMD were obtained. Findings: Players who had higher BMI got higher BMD. The strongest significant positive correlations found were lean mass, body weight, and BMI with BMD of the arms, legs, trunk, and spine. Conclusions: Most of the players analyzed had problems of excess weight and obesity, however, those who had a higher BMI such as obesity type I, II and III had also higher BMD than those with excess weight and normal weight, with significant differences in the regions of arms, legs, spine and total body.

Objetivos: El objetivo de este estudio fue relacionar el índice de masa corporal (IMC) y la composición corporal con la densidad mineral ósea (DMO) en jugadores de fútbol americano universitario. Métodos: Participaron un total de 90 jugadores (22.44 + 1.71 años de edad), de la liga mayor de fútbol americano universitario en México. Se utilizó el equipo de la absorciometría dual de rayos X (DEXA), en la cual se obtuvieron los valores del IMC, masa grasa, masa magra, masa total y la DMO. Resultados: Los jugadores que presentaron un mayor IMC obtuvieron una mayor DMO. Conclusiones: si observamos que la mayoría de los jugadores suelen tener problemas de sobrepeso y obesidad, encontramos que la masa grasa no se asocia con la DMO, es decir, que el jugador a pesar de tener un peso corporal elevado, su beneficio de la elevada DMO se debe a la alta cantidad de masa magra.
