ABSTRACT Aims: Our study has two aims. The first aim is to investigate the factors associated with musculoskeletal disorders and pain in adolescents; the second aim is to identify adolescents with pain and limitation of movement and refer them to the appropriate specialist. Method: The total number of students in the 5 selected schools was 3589. The sample size calculated with 95% confidence was 347. Our study is cross-sectional and was conducted between September 2017 and June 2018 with a total of 525 students, using simple random sampling from 5 schools. A questionnaire form, an anthropometric measurement form and the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) for students were used as data collection tools. Results: 51,6% of the students were female and the mean age was 14.08 years. The mean age was min: 10.0, max: 18.0 and standard deviation: 2.124. The mean pain score and pain intensity in the neck, shoulder, back, waist and wrist were found to be higher in female students (p0.05). However, with regard to BMI, it was found that overall mean scores and mean scores for feeling pain were significantly higher in lean males than in normal/overweight or obese males (p0.05). Ancak BKİ açısından zayıf erkeklerde genel puan ortalamaları ve ağrı hissetme puan ortalamalarının normal/fazla kilolu veya obez erkeklere göre anlamlı derecede yüksek olduğu bulunmuştur (p<0.05). Sonuç: Kızların erkeklere göre daha fazla ağrı bildirdiği, düzenli spor yapma, teknolojik cihazları uzun süreli kullanma, sırt çantası taşıma ve vücut kitle indeksinin kızlarda ağrı ile ilişkili olmadığı bulunmuştur.
