Enquesta de salut de Catalunya
Latest data from the 2013 Health Survey shows that 81,1% of the population consider themselves as healthy, slightly better that in 2010 that was 79,3%. Regarding satisfaction, 86,9% of population is satisfied with public health services, again better than 2010 that was 84,7%. Though in 2012 results were a little bit better.
In the details of the results you'll find that obesity and overweight is the biggest issue to address in my opinion. There is still a lot to do on tobacco and alcohol, but data shows some improvement.
This health survey should be broadcast in the media and efforts to promote healthy behaviours should raise. Unfortunately nowadays media is focused on negative messages and this issue lies far from journalists' interests.
