Intervention(s)

Intervention group (charitable donationgroup) Intervention consists of donations to the Japan Committee for UNICEF; donations are calculated based on the amount of increase in average number of steps walked per day during the 3-month intervention period, compared with baseline walking levels (pre-intervention two-month average). 1) If the increase in the daily average number of steps walked during the intervention period is at least 1 step/day above the baseline walking level, 1 Japanese yen is donated for each step over the average. 2) If the average number of steps walked during the intervention period is 9,000 steps/day (males), or 8,500 steps/day (females), 1,000 Japanese yen is donated. Universal interventions: i.Setting of step targets ii.Self-monitoring of steps iii.Twice-monthly notice (e-mail) from the health center to encourage increases in steps taken, and to inform participants of their average number of steps.
Control group (waitlist control) Only the following interventions will be performed: i.Setting of step targets ii.Self-monitoring of steps iii.Twice-monthly notice (e-mail) from the health center to encourage increases in steps taken, and to inform participants of their average number of steps.
