Aih. Borge et al., PREVALENCE AND PERSISTENCE OF STOMACH ACHE AND HEADACHE AMONG CHILDREN - FOLLOW-UP OF A COHORT OF NORWEGIAN CHILDREN FROM 4 TO 10 YEARS OF AGE, Acta paediatrica, 83(4), 1994, pp. 433-437
Results from a prospective cohort of 136 children, from 4 to 10 years
of age, indicated that stomach ache was almost as prevalent among pres
chool children as children of school age. Headache was almost absent a
mong 4-year-olds but prevalent at 10 years of age. Generally, early pa
in complaints were persistent. The co-occurrence of stomach ache and h
eadache increased from 4% of children at 4 years of age to 20% when th
ey reached 10 years of age.
