There are many proposed causes of<unk>  and it is likely the result of multiple interacting factors. Understanding of the causes of<unk>  is incomplete, however changes in hormones, immobility, age-related muscle changes, nutrition and neurodegenerative changes have all been recognized as potential causative factors. The degree of<unk>  is determined by two factors: initial amount of muscle mass and rate at which muscle mass declines. Due to variations in these factors across the population, the rate of progression and the threshold at which muscle loss becomes apparent is variable. Immobility dramatically increases the rate of muscle loss, even in younger people. Other factors that can increase rate of progression of<unk>  include decreased nutrient intake, low physical activity, or chronic disease. Additionally, epidemiological research has indicated that early environmental influences may have long-term effects on muscle health. For example, low birth weight, a marker of a poor early environment, is associated with reduced muscle mass and strength in adult life.
