The North east region (?=39.3, ?=9.0 per 100,000 inhabitants, significant temporal decrease) and North region (?=37.3, ?=8.9 per 100,000 inhabitants, significant temporal decrease) expressed the highest coefficients. Stood out the female population (?=58.5%, ?=1.01%, significant temporal decrease), the elderly (?=56.7%, ?=0.79%, stable) and brown people (?=39.1%, ?=1.2%, stable).
