Iodine is an indispensable micronutrient
essential for the normal, physical, mental development, and well-being
of all humans. Although Sokoto State has long been considered iodine
sufficient, increasing evidence suggests that it might now be mildly to
moderately iodine deficient. The study assessed whether mild to moderate iodine
deficiency in adolescent’s girls was associated with an adverse effect on
academic performance. Systematic random sampling study was conducted among
public secondary schools of the three zones of Sokoto State, 248 girls aged 14
– 17 were recruited. Performance in English and Mathematics was assessed using
quasi experimental method. Validated pre-test and post-test questionnaires were
used to assess subject’s demographical data. Interval plot was used for mean
scores in performance of English and Mathematics of the study subjects, column
charts was used for comparing grades of performance in English and Mathematics
of the subjects in the zones. Result in means scores showed 54.4 in SCZ
subjects and 54.1 in SWZ subjects compared to 38.5 in SEZ subjects. Grades of
Performance in English and Mathematics showed 28.9% subjects in SCZ, 32.9%
subjects in SWZ compared to 41.7% subjects in SEZ, scoring below satisfactory
level ranging from fair and poor performance. Inadequate iodine level is seen
to be associated with decrease in academic performance of the study subjects.
Adequate iodine intake should continue to be encouraged in the general
population more especially in the secondary schools girls, most of whom are at
the verge of becoming mothers of children who would be enrolled in schools.
