More than one-third of respondents in the Slovak Republic reported an activity limitation induced by health problems, compared with only 15% in Iceland and Sweden. On average, 17% of the population is obese in the OECD (Figure 5.7). The proportion of obese people varies from about one-third in the United States and Mexico, to around one-in-four in New Zealand, Chile, Australia and Canada, to less than 5% in a number of Asian countries including India, Indonesia, China, Japan and Korea. Rates of obesity have risen rapidly in recent decades, affecting all population groups to varying extents, with more educated and higher socio-economic status women displaying substantially lower rates, and mixed patterns being observed for men (Sassi, 2010).
