Results from a prospective cohort of 136 children, from 4 to 10 years of age, indicated that stomach ache was almost as prevalent among preschool children as children of school age. Headache was almost absent among 4-year-olds but prevalent at 10 years of age. Generally, early pain complaints were persistent. The co-occurrence of stomach ache and headache increased from 4% of children at 4 years of age to 20% when they reached 10 years of age.
一项针对136名4至10岁儿童的前瞻性队列研究结果表明，学龄前儿童胃痛的发生率几乎与学龄儿童相同。4岁儿童几乎没有头痛症状，但10岁时头痛症状很普遍。一般来说，早期疼痛症状持续存在。胃痛和头痛同时出现的情况从4岁儿童中的4%增加到10岁时的20%。
