[Incidence and prevalence of @entity299 and XXXX in Spain: a systematic review of the literature].

@entity1 @entity66 @entity299 @entity583 @entity65
@entity65 morbidity is not well documented in Spain, due to the fact that there is no comprehensive and reliable data source. This study sought to describe the population frequency of @entity299 and @entity66 in Spain. We used bibliographic search strategies in four different databases to identify scientific studies published in Spanish medical journals or by Spanish authors after 1990. We then selected studies drawn from population-based registers, prevalence surveys and cohort studies, from which age-adjusted incidence and/or prevalence rates could be extracted. We identified 19 papers published in the period 1993-2005, containing valid information on @entity65 population incidence or prevalence in Spain. Acute @entity583 incidence rates per 100,000 population ranged between 135-210 and 29-61 new cases annually for @entity1 and @entity1 aged 25-74 years, respectively. Acute @entity583 prevalence rates were not available, but a study of prevalence of angina showed rates of 7.3% in @entity1 and 7.5% in @entity1 . @entity66 incidence rates per 100,000 population ranged between 364 for @entity1 and 169 @entity1 , in aged 69 years and over rising to 2.371 in @entity1 and 1.493 in @entity1 . Prevalence rates in population aged 65 years and over would be estimated in 7% in @entity1 and 6% in @entity1 . Although currently available information may serve as an initial reference, monitoring of the incidence and prevalence of these diseases will nevertheless call for an effort which exceeds the capacity of isolated research teams.
