Results: The sample was 100 adults between 60 and 70 years old. There was not a correlation between caloric intake and Body Mass Index in males nor females (P>0.05). There was a good negative correlation between physical activity and body mass index (r=-0.56) and a negative lineal relationship (P<0.05). There was a relationship between physical activity and overweight/obesity (X2= 47.29, df 1 P=.00001) and OR=102.60.
