SINGAPORE – With “Western-style” ailments such as obesity and diabetes on the increase in Asia, health-related businesses are ramping up their efforts to keep those diseases at bay. Asia’s spending on health care has been soaring. By 2017, the region’s expenditure will reach $2.1 trillion, 24% of the global total, according to a report by The Economist Intelligence Unit. “As incomes rise, education levels also improve, creating much greater awareness of health issues,” the report said. But as Asians earn more, they are becoming not only better educated but also more susceptible to so-called “lifestyle” diseases — afflictions the World Health Organization classes as “noncommunicable” and “chronic.” Chronic maladies such as heart disease and diabetes are the No. 1 killers in Southeast Asia, accounting for 62% of all deaths, according to the WHO. Growing Asian affluence and the spread of fast-food chains have led to increasingly unhealthy eating habits, as foods high in fat, salt and sugar are consumed in greater amounts. This, in turn, has caused a spike in conditions previously more common in Western countries. Malaysia-based IHH Healthcare is among the hospital operators responding to the region’s growing medical needs. “Rapid growth, rapid rise in affluence and the development of the middle income group, these are all very favorable factors for the health care industry,” said Tan See Leng, IHH’s managing director and CEO, speaking at the FT-Nikkei Asia300 Forum in Hong Kong on April 25.
