Bulletin 16 - Age and sex distribution
Age and sex distribution
The age distribution of persisting cases of SCI from traumatic causes is
presented in Figure 3. The age group of 10 to 14 years was excluded from the
figure because of a suspected poor coverage of this group by the SUs. It is
evident that the highest case count and age specific rate occurred in the age
group 15-24 years (age specific rate was 26/1,000,000 of population). This age
group comprised 30% of the persisting cases of SCI from traumatic causes. With
increasing age, the age specific rate declined to the age group 45-54 years,
after which there was a relatively strong increase from the age groups 55-64
years to 65-74 years. There was a statistically significant difference in the
rates between the age group 15-24 and each of the ten year age groups from 35
years to 64 years. The only other statistically significant difference in the
rates was between the age groups 25-34 years and 45-54 years. None of the other
differences in the rates between the age groups, that are apparent in the
figure, were statistically significant.

Note: excludes 5 cases where age was 10-14 years and 1 case where age was not
reported
Of the persisting cases of SCI from traumatic causes, 77 per cent were male and
23 per cent were female. Figure 4 shows that the male rate was substantially
higher than the female rate at all age groups except for the 75 plus age group.
The difference in the rates was statistically significant for all age groups
with the exception of 55-64 years and the 75 plus age group. The ratio of the
male to female rates ranged from 3.1:1 (in the age group 24-34 years) to 5.1:1
(in the age group 45-54 years).
