The aim of this study was to assess the relation between the diagnosis of encopresis at 8 and 10 years of age, and mental and somatic health 10 years later. The importance of type of encopresis (primary or secondary) at 8 years was also studied. Subjects were a non-clinical encopretic sample (N=73) and control subjects (N=75) [2]. Seven assessment variables from conscription surveys provided information about mental and somatic health status at 18 years of age. Former encopretics (n=66) did not differ significantly from the controls (n=67) at 18 years of age, although there were consistent, small negative differences. The boys who at 10 years of age had still been encopretic did not differ significantly at 18 years of age from the boys who at 10 years had recovered from encopresis, and the signs indicating the small differences varied. For former primary and secondary encopretic boys, there were two significant differences, the men in the secondary group being more often exempted from conscription than the primary group and the control cases. The results indicate that boys with non-clinical encopresis show only small, if any, mental and somatic disturbances at the beginning of adulthood. Comprehensive investigations of encopretic patients are recommended as important clinical problems, in addition to encopresis, might be present.
