2.3.2. Falls
The participants were asked whether they had experienced a fall (0 = no, 1 = yes), defined as instances of accidentally losing their balance and falling on the ground or against an object such as furniture in the prior two months as part of a self-administered questionnaire. Additional efforts to verify a fall experience were not conducted. The falls were assessed at baseline and again at 1, 2, 3, 5, and 10 years posttest. The primary analyses predicted the likelihood of prospective falling for all participants. Subgroup analyses were also conducted on those with a higher baseline risk of falling, defined as those who experienced a fall in the two months prior to baseline.
