Is sedentary behavior increasing with age?
Podrekar Nastja, Kozinc Žiga, Šarabon Nejcsedentary behavior young workers, older workers correlation
Sedentary behavior has been identified as a significant risk factor for pre-mortality independently of daily physical activity. At the same time the number of older adults remaining at work increases nowadays. The issue of sedentary behavior in older adults is therefore a growing field of research. ...
