Abstract
To investigate if blindness influences the growth rate of young subjects we measured height and weight of 71 prepubertal blind subjects (33 females and 38 males) aged 7–10 yr, in Tanner stage one puberty, living at the Institute “Martuscelli’ for young blind individuals in Naples, Italy. They were divided into two groups: group 1 consisting of 27 subjects (14 females and 13 males) with total blindness; group 2 consisting of 44 subjects (20 females and 24 males) having only a light perception. The distribution in quintiles of their height and weight was compared by X2 test for trend to that of an age-matched large population (7902 subjects: 3808 females and 4094 males) of primary school from the same district. A stature significantly lower than controls was evidenced in both group 1 (p = 0.0006) and in group 2 (p = 0.008). When the comparison is performed taking into account the sex of subjects, the girls of both group 1 (p = 0.0014) and group 2 (p = 0.0004) show a stature significantly lower than female controls, whereas the stature of boys of both groups did not differ from that of male controls. No statistically significant differences in weight distribution were found between controls and either group 1 and group 2. Our results suggest that total or partial blindness could influence negatively the growth of prepubertal subjects; in particular it can cause short stature or growth delay especially in female sex.
