The consolidation of nephrology as a medical specialty is relatively new and its denomination does not intuitively reflects its true scope. To assess the degree of knowledge from a population sample regarding the term "nephrology". We carried out a cross-sectional study in Niterói, RJ, with adult passerby individuals answering to the question "Do you know what nephrology is?". The variables recorded included: gender, age, skin-color, residence, income, educational level and kidney-disease history in the family. p values < 0.05 were considered significant. Of the 564 individuals asked, 504 were willing to answer. Of those who refused, 64% were males, 58% caucasians--from whom 85% were aged > 30 years. The mean age among participants was 39 (22-56) years, 49% were males and 56% caucasians. Twenty-eight percent of the interviewees knew the term "nephrology". Their knowledge came from school (39%) and family (30%). Those who knew about the term "nephrology" were older (42 ± 17 vs. 39 ± 17 years, p < 0.05), had higher income (R$ 4,522 vs. R$ 2,934, p < 0.05) and higher education (27% vs. 12% with complete higher education, p < 0.001). They were predominantly caucasians (64% vs. 53%, p = 0.001), and had a higher rate of renal disease in the family (55% vs. 36%, p < 0.001). In the multivariate analysis, associations were maintained for age (OR 1.02; 95% CI 1.00 to 1.03, p = 0.004); higher education (OR 10.60, 95% CI, 4.20 to 26.86, p < 0.001) and kidney disease in the family (OR 2.2, 95% CI, 1.40 to 3.41, p < 0.001). Only 28% knew the term "nephrology", illustrating the specialty's low penetration. We must strive to popularize this field of medicine aiming at better educating the population concerning the prevention and care of kidney diseases.
