Cost-effectiveness of a community-based obesity control programme

Abstract

We evaluated two 12-week long community-based obesity control programmes in Korea. One was a visiting-type programme (V-type) (n = 515) administered by a public health centre and the other was a remote-type programme (R-type) (n = 410) utilizing an Internet website and mobile phones with a short message service. The total cost for the intention-to-treat subjects was US$116,993 in the V-type programme and $24,555 in the R-type programme. In the per-protocol subjects, 66% of V-type participants (n = 117) achieved the target bodyweight reduction (5%) and 13% of R-type participants (n = 15). In the per-protocol subjects, the cost per person was $227 (V-type) and $60 (R-type). The cost per person achieving the target weight reduction was $975 (V-type) and $1637 (R-type). The average amount that participants were willing to pay was $71 (V-type) and $21 (R-type). The cost-effectiveness of the visiting-type community-based, short-duration obesity control programme was higher than the remote-type programme.
