*Physical activity levels (during work and at leisure time) reflect the physical activity continuum, ie, sedentary, low, moderate and high. For leisure-time physical activity, these categories roughly indicate: spending most leisure time sitting (sedentary), occasionally engaging in light intensity physical activities during leisure time such as slow walking or household activities (low), engaging in physical activities of moderate intensity such as intense household activities or brisk walking (moderate), regular engagement in high intensity physical activities such as jogging or cycling, thereby meeting physical activity guidelines (high). For occupational physical activity, categories roughly indicate: mainly sitting work (sedentary), work that mainly involves standing or walking, but without lifting or carrying loads (low), work that involves carrying light objects or walking stairs (moderate), highly physically demanding works involving frequent carrying or lifting heavy loads (high).
