By moderate physical effort, I mean tasks that caused light sweating or a slight to moderate increase in your heart rate or breathing, such as raking leaves, mowing the lawn, or heavy cleaning.

5 Comparison to others Sedentary Meeting recommendation for physical activity (USDHHS 2008) Categorical variable either yes (1) or no (0): minutes/week moderate intensity aerobic - or 75 minutes/week vigorous intensity aerobic - or an equivalent of mixed combination of moderate and vigorous intensity aerobic by multiplying vigorous minutes by 2. PAMEET PAD440 X X X (1) more active, (2) less active, or (3) about the same PAQ520 TV/Video X X (0) less than 1 hour, (1) 1 hour, (2) 2 hours, (3) 3 hours, (4) 4 hours, (5) 5 hours or more, (6) none. Computer X X (0) less than 1 hour, (1) 1 hour, (2) 2 hours, (3) 3 hours, (4) 4 hours, (5) 5 hours or more, (6) none. PAD590 PAD600 *Frequency was answered in number of times per day, week, or past 30 days for the past month. This was converted to average frequency per week. For days, the values were multiplied by 7 to obtain a week. For past 30 days, the values were divided by 30 and then multiplied by 7 to obtain a week. **Duration was answered in average number of minutes or hours. Minutes were converted to hours. ª This question was required to be at least 10 minutes in length. The variable should be checked and if less than 10 minutes in length should be set to zero and calculated as no activity for this mode.
