Abstract:
Background: The ergonomic suitability of classroom furniture plays a crucial role in students' comfort, posture, and overall musculoskeletal health. However, in many developing countries like Nigeria, school furniture often does not align with the anthropometric measurements of students, leading to discomfort and potential long-term health risks.

Objectives: This study aims to evaluate the mismatch between the anthropometric measurements of school children and the dimensions of classroom furniture in Lagos State, Nigeria. It also seeks to investigate the potential musculoskeletal implications of this mismatch on students’ health.

Methods: A cross-sectional study was conducted among 164 students from public and private schools in Lagos State, aged 10-17 years. Multistage Sampling Technique with Simple Random Sampling used at each stage to select participants. Anthropometric measurements such as weight, stature, popliteal height, and elbow height (sitting) were taken using standard and appropriate instruments and also follow ISAK recommendation. Classroom furniture dimensions, including seat height, seat depth, and desk height were measured. The ergonomic fit of the furniture was assessed by comparing students’ body dimensions with furniture dimensions. Pain and discomfort were graded using a Visual Analog Scale (VAS).

Results: The study revealed significant mismatches between the students' anthropometric measurements and the classroom furniture dimensions, particularly in popliteal height vs. seat height, buttock-popliteal length vs. seat depth, and elbow height (sitting) vs. desk height. However, there are some furniture dimension which match the students’ anthropometry measurements. Furthermore, the outcome of pain for students’ varies across age groups and school category.

Conclusions: The findings highlight the urgent need for ergonomically designed classroom furniture that aligns with the anthropometric characteristics of Nigerian school children. Properly fitted furniture could reduce discomfort and prevent musculoskeletal issues, thereby promoting better health and learning outcomes. Policymakers and school authorities should prioritize adjustable or size-appropriate furniture to cater to the diverse needs of students.
