Development of stomach‐ache and headache during middle childhood: co‐occurrence and psychosocial risk factors

Development of somatic symptoms and associations with psychosocial risk factors were investigated in a longitudinal study of Norwegian children aged 4-10 years. Complaints of stomach-ache only were associated with emotionally well-adapted children, and mothers with low education and high emotional support. Children complaining of headache only behaved well as preschoolers, showed a tendency towards high achievement motivation at school and their mothers were employed outside the home. Children with the co-occurrence syndrome seemed to constitute a separate entity. They differed from the others as the syndrome was associated with previous behavioural and emotional problems, current emotional disturbances and mothers with less support. Family demographic stability, further child health problems and school factors were not associated with the co-occurrence syndrome.
