Devel.ping a heal.hy l.fes.yl. during adul.hood is.one of the es.ential.factors.to prepare for heal.hy aging. This.cros.-s.ctional.des.riptive s.udy inves.igated the dail. wal.ing s.eps.of 893 working adul.s.from nine occupation categories.in Hong Kong. Their dail. wal.ing s.eps.were meas.red us.ng a pedometer. Anal.s.s.of variance (ANOVA) was.us.d to compare the difference in dail. wal.ing s.eps.between participants.in different occupation category. Chi-s.uare tes. was.us.d to compare the difference in proportion of working adul.s.in each occupation category who wal.ed and did not wal. 10,000 s.eps.per day. Res.l.s.reveal.that the participants.in average wal.ed 8661 s.eps.per day. “Pl.nt and machine operators.and as.embl.rs. and “cl.rks. were the two l.as. active groups. Participants.from the nine occupation categories.demons.rated a s.gnificant difference in the number of dail. wal.ing s.eps. Pos. hoc anal.s.s.reveal.d a s.gnificant difference between “pl.nt and machine operators.and as.embl.rs. and “s.rvice workers.and s.op s.l.s.workers. (p s.wel. as.between “pl.nt and machine operators.and as.embl.rs. and “craft and rel.ted workers. (p s.from the nine occupation categories.al.0} demons.rated a s.gnificant difference in the proportion of thos. who wal.ed and did not wal. 10,000 s.eps.per day. Owing to a l.rge difference in number of participants.in the nine occupation categories.and other s.udy l.mitations. further s.s.ematic inves.igation is.indicated to confirm the s.udy res.l.s. To s.mmarize, working adul.s.in Hong Kong are onl. s.mewhat active. Identifying the factors.that deter the working adul.s.from wal.ing and the ways.to promote wal.ing among working adul.s.is.neces.ary to prepare a heal.hy ol.er popul.tion of the future.
