Abstract
Background and Aims: Given the high prevalence of obesity and overweight among teachers and its critical role in exacerbating musculoskeletal disorders and postural abnormalities, the present study aimed to investigate the association between obesity indices and musculoskeletal disorders and postural abnormalities in non-athlete male and female teachers.
Materials and Methods: This descriptive-analytical cross-sectional study was conducted on 200 overweight/obese teachers. Data on musculoskeletal pain were collected using the Standardized Nordic Musculoskeletal Questionnaire and the Visual Analogue Scale. Anthropometric obesity indices were measured using a body composition analyzer. Postural abnormalities were assessed through specialized diagnostic methods. Statistical analyses were performed using Pearson correlation and one-way ANOVA tests at a significance level of P < 0.05.
Results: Pearson correlation analysis revealed significant associations between all anthropometric obesity indices and postural abnormalities, including forward head posture, protracted shoulder posture, and lumbar lordosis, as well as the prevalence of pain in the neck, shoulders, lower back, knees, calves, and ankles (P < 0.05). One-way ANOVA results showed no significant differences in musculoskeletal disorders or pain between genders (P > 0.05). However, significant differences were observed in forward head posture, thoracic kyphosis, and pain in the neck, lower back, and knees across different teaching levels (P < 0.05).
Conclusion: The findings of this study demonstrate a significant role of obesity in the development and severity of musculoskeletal disorders and postural abnormalities among non-athlete teachers. These results highlight the need for preventive and tailored interventions focusing on weight management, enhancement of physical health and activity, and improvement of ergonomic conditions in the workplace, adapted to the specific needs of teachers across different genders and educational levels.
