Abstract [en]

Background: In 2014, there were nearly 2 billon overweight people around the world. This causes excessive costs for the society and is also a threat to the human condition. In recent time, there has been an increase of understanding the individual parts of the body composition. One method to measure body composition is using a bioelectrical impedance analyzer. The current recommendation is to measure during fasting conditions. However, there are few studies that have investigated a meal’s effect on body composition measured with bioelectrical impedance analysis, and those studies have presented varying results. If a bioelectrical impedance analyzer could be used without previous fasting, it would increase the use and utility of bioelectrical impedance analyzers. This could in turn, for example, reduce waiting lists in hospitals where bioelectrical impedance analyzers are used. Aim: The main aim of this study was to investigate a meal’s effect on body composition when measured with a bioelectrical impedance analyzer. The secondary aim was to investigate the correlation between skeletal muscle mass and hand grip strength when using a bioelectrical impedance analysis and a hand-held dynamometer respectively, during fasting conditions. Methods: In this present study, 27 subjects in the age of 21-59 years old participated. The subjects arrived at the laboratory in the morning during fasting conditions. Firstly, a bioelectrical impedance analyze and a hand grip strength test were completed. Thereafter, all subjects ate a meal containing at least 500 kcal. The following bioelectrical impedance analysis were completed 60, 90 and 120 minutes’ post meal intake. The data was then analyzed in SPSS version 20 through a paired T-test and a Pearson correlation test respectively. Results: The results showed that all body composition parameters investigated in this present study, except for minerals, not were statistically different 90 minutes after a meal intake containing at least 500 kcal, compared to the fasting condition, when measured with a bioelectrical impedance analyzer. Furthermore, a moderate correlation was found between hand grip strength and skeletal muscle mass for women. The same correlation was found weak for men. Conclusion: The results from this present study indicates that it is possible to measure body composition with a bioelectrical impedance analyzer 90 minutes’ post meal intake, except for minerals. Also, it indicates that a hand grip strength test is not a valid test for measuring skeletal muscle mass.
