By the year 2000, there will be one million elderly persons in Hong Kong. With the rise of an older population, the cost of health care is likely to increase. Studies conducted in Hong Kong have shown that over 30% of health care expenditure is spent on the elderly. Unless steps are taken to slow the onset of chronic illnesses in elderly people, health care expenditure will increase rapidly in the future. The present paper describes strategies that have been adopted for promoting a healthier elderly population in Hong Kong. The paper also reports the results of an evaluative study on the largest health promotion program for older people in Hong Kong. It seems to show that health promotion activities may have the potential to save lives, delay institutionalization, and improve life satisfaction.
