The tonga healthy weight loss program 1995-97.

A health and weight awareness program was initiated in 1995 by the Tonga National Food and Nutrition Committee to combat a high prevalence of obesity and its associated non-communicable diseases. The strategy of the program was to provide a fun activity in which people wanted to join, and at the same time gain health benefits. Three successive weight loss competitions were organized, of 4 to 6 months in length, in which radio, television, and newspaper media were major elements. A Tongan version of the 1993 South Pacific Commission weight for height chart was produced, allowing identification of overweight/obesity using body mass index. Participants were registered and given individual encouragement on diet/exercise. Prizes donated by local businesses added to the campaign, as well as the involvement of His Majesty King Taufa'ahau Tupou IV. Aerobic exercise, public walks, weigh station manager training, and weight watcher group meetings were special activities. An unexpected element was the interest by the international press, which proclaimed the Tonga national weight loss competitions to be the first in the world. A total of 3429 participants registered in the three competitions, with 1617 competing to the end. First place winners lost from 25.5 to 28.4 kg in the competitions. Difficulties encountered included problems of coordination, funds, scales, newness of the healthy weight concept, and weight gain at the close of the competition. The activity was received positively by the community, with requests for the competitions and exercise activities to continue, and much awareness on health issues relating to overweight was achieved.
