Harris lines were assesed in 194 right tibiae of prehispanic inhabitants of Gran Canaria, belonging to 52 adult females and 123 adult males. No Harris lines were detected in 45 (23%) of the adult individuals, 13 females (25%) and 26 males (21%), these differences being not statistically significant. Female tibiae showed a slightly lower mean number of Harris lines at the distal end than males ones (1.692+-1.681 in females vs 1,91+-1.825 in males). Ages at wich Harris lines were formed showed two peaks, a major one at the age of 1 year, and another between 15 and 16 years in males and between 11-12 and 14- 15 years in females. Harris lines were more frequently at the distal than at the proximal end of the bone . The relative low number of lines detected in our population when compared with the high prevalence of osteoporosis among the adult population of this island is striking.
