A survey of 248 individuals was carried out. They included both males and females aged between 16 and 80 years, and they were selected as a representative sample of the population on care in the health center "Huerta de la Reina" for an error margin of 5% and p less than 0.05. The possible influence of cultural and socioeconomic factors on the opinion of the population about the received attention and the degree of use of health care services was evaluated. 76.2% of our patients are not working, 68.5% are females and 57% are older than 46 years. These two groups show the highest rate of consultation for administrative purposes. The educational level, profession, sex, age and the district of origin do not influence the evaluation of the received care. The patients from the quarter with the lowest socioeconomic status consider that the physician pays less attention to them and have a poorer understanding of the latter's explanations (p less than 0.05). Both factors exert an influence on the evaluation of the new model of care. It was concluded that the socioeconomic characteristics of a population are very important for the development of an integrated type of attention by primary care teams.
