The Site of Musculoskeletal Pain in School Children with Excessive Body Weight and Obesity in Bosnia and Herzegovina

INTRODUCTION: The number of school age children with excessive body weight and perception of musculoskeletal pain is on the rise. AIM: The aim of this study is to identify the most common sites of acute and chronic musculoskeletal pain in school children with excessive body weight and obesity. METHODS: A survey included 1315 children aged 9-14 years from September 2016 to January 2017 in the Primary schools of Canton Tuzla. The weight and height were measured for each subject based on which a body mass index was determined and two groups were categorized: a group of children with excessive BMI and obesity (N = 406), and the remaining respondents were part of the control group. The Nordic questionnaire was utilized to examine places of perception of musculoskeletal pain experienced by children in the preceding 7 days (acute) or preceding 1 year (chronic pain). RESULTS: Prevalence of overweight and obesity in school children is 31% (significantly higher in boys than in girls, 38%: 25%). The incidence of acute and chronic pain in children with normal BMI 49% is significantly higher than in excessive BMI 45% or in children with overweight 39.1%. Obesity and overweight are risk factors for the development of nonspecific musculoskeletal pain (OR = 1.161, 95% CI, 1.020-1.322). The most common places for chronic pain associated with overweight and obesity are neck (OR = 1.212, 95% CI, 0.893-1.644) and knee (OR = 1.103, 95% CI, 0.690-1.760). While the most common place of acute pain is knee (OR = 1.127 , 95% CI, 0.673-1.890). CONCLUSION: The relationship between excessive body weight and chronic musculoskeletal pain (MSP) in the neck and knees indicates the cumulative effect of exposure to excessive body weight and obesity in BiH school children.
