OBJECTIVES: (1) To determine the prevalence of joint hypermobility in children aged 4-14 years old without organic disease of the locomotor system; (2) to compare the prevalence of hypermobility in children with and without arthralgia and (3) to analyze the influence of certain variables on the development of arthralgia. PATIENTS AND METHODS: We performed an observational study in a sample of children aged 4-14 years old living in Area 4 of the Community of Madrid (Spain). Joint hypermobility was evaluated using a goniometer. Hypermobility was defined using Beighton's criteria. RESULTS: A total of 222 subjects were analyzed: 176 in the primary care setting and 46 in the emergency department of a referral hospital. Of the 222 children, 43 reported arthralgia. The prevalence of hypermobility (> or = 4 criteria) was 55 % (123/222), reaching 71 % (49/69) in children aged less than 8 years. No significant differences were found in the prevalence of hypermobility in children with and without arthralgia (65 % and 53 % respectively). Of the variables analyzed (age, sex, country of origin, primary care/emergency department setting) only differences in the absolute number of Beighton criteria present in children with and without arthralgia (4.34 +/- 2.47 and 3.48 +/- 2.35, p = 0.03) were detected, which disappeared when at least four criteria (definition of hypermobility) were required. CONCLUSIONS: Fifty-five percent of the population studied and 71 % of those younger than 8 years old met the criteria for joint hypermobility. In the sample analyzed, the presence of joint hypermobility did not seem to favor the development of arthralgias.
