The system can also spot damaged packs, and uses
weight estimation to identify missing packs or
items,
for example missing toys in the
children packs.
For one
item not available in the NATSISS (having seen a health professional in the past year), we made comparisons with the National Aboriginal and Torres Strait Islander Health Survey (NATSIHS), a similar ABS household survey of 5757 adults and 4682
children conducted from August 2004 to July 2005, using similar person and replicate
weights.18 We also investigated the effect of the slightly different definitions of smoking status in our survey, the NATSISS and the Australian ITC Project surveys.
