Objective:

To know the prevalence of diseases according to the blood group of the population studied in the province of Cuenca (Spain).

Methods:

An observational, descriptive, cross-sectional, and population-based study. The sample is 73 people (39 men and 34 women), over 60 years. All blood groups were identified, studying them by age and gender.

Results:

The percentages of blood groups of the population studied by gender are 42.6% (group A), 42.4% (O), 13% (B) and 1.4% (AB). A+ predominates (35.6%), followed by O+ (27.4%).The prevalence of a certain disease based on blood group is studied. In this sense, differences are detected within the same group, according to the Rh factor. Rh positive groups suffer more from hypertension, insomnia and depression than Rh negative groups. Groups A and 0 O suffer a greater increase in cholesterol than those of group B. Those in group 0 O have more hypertension than the rest and the 0O + suffer a higher percentage of anemia (Fe), while those A + anemia (B12). Osteoporosis is greater in the negative groups than in the positive ones, except in the AB + group.

Conclusions:

The blood group with which we are born can condition the diseases that we will suffer throughout our lives. Being 0 could predispose them to have hypertension, anemia (Fe), cholesterol, lung diseases and insomnia, while A could predispose them to have depression, anemia (B12) and prostate problems in men.
