The screening questionnaires were answered by 256 middle
aged and elderly adults in the community. A total of 156
subjects were included on the basis of the inclusion criteria.
However, 31 of the 156 subjects were excluded because they
were not interested in the intervention program or other
causes. Among the remaining, 125 subjects, 23 subjects were
further excluded because they disagreed with the collection of
blood sample. Therefore, 102 subjects were initially included
in our research, but 6 subjects dropped out before the start of
our intervention program.
