Evaluation of the guidelines and children's ability to select the anthropometrically recommendable height of school furniture: A case study of Korean primary school children

Discrepancy between pupils’ body and classroom furniture in elementary schools: A case study in the Republic of Kosovo

BACKGROUND: Primary school children spend quite a lot of time sitting in classrooms. For this reason, it is necessary to make a scientific analysis of children’s body dimensions and compare them with the furniture dimensions where they sit. OBJECTIVES: The main aim of this paper is to present anthropometric data for pupils in primary schools in the Republic of Kosovo and give recommendations for school furniture design. METHODS: Measurements were made in the public schools of four different regions in the Republic of Kosovo. The study includes 720 children from 12 different elementary schools with first and fifth graders (6–11 years old).- Twelve body parts were measured: Stature, sitting height, shoulder height, lower leg length, hip breadth, elbow height, buttock-popliteal length, thigh clearance, eye height, shoulder breadth, and knee height. The descriptive data are calculated in terms of average, standard deviation, and 5th, 50th and 95th percentile. RESULTS: We recommend that the competent authorities in the Republic of Kosovo consider improving the infrastructure of primary schools in terms of furniture size according to the findings presented in this study. CONCLUSIONS: The information presented in this paper on pupils’ anthropometry and the proposed dimensions for school furniture can be used by various bodies in Kosovo including, but not limited to: Ministry of Education Science and Technology,Ministry of Trade and Industry of Kosovo and furniture manufacturing industries as basic information for suitable furniture design for primary school children, as well as school principals to help in furniture selection.

Anthropometric perspective to classroom furniture ergonomics and the need for standards in Nigerian schools

BACKGROUND: Classroom furniture designs have been implicated in musculoskeletal disorders among school age persons due to high level mismatches between the furniture dimensions and users’ anthropometrics. OBJECTIVE: The objective of the study was to analyze classroom furniture ergonomics at selected primary, secondary and tertiary educational institutions in Nigeria and to understand if there are noticeable patterns in the match/mismatch. METHOD: Anthropometric measures relevant to furniture design were obtained from primary and secondary school children as well as from university undergraduates. The dimensions of classroom furniture available to the participants were also taken and an assessment of the suitability of the furniture was completed. RESULT: The ergonomic evaluation of the classroom furniture available to the study participants revealed enormous discrepancies between the furniture dimensions and the anthropometric measures of the users. In addition, a pattern was observed in the way the matches/mismatches occurred. The furniture dimensions that matched majority of the users tend to match across the three categories and those that did not match majority of the students, also followed the same pattern. CONCLUSION: The study presents remarkably high levels of mismatches between classroom furniture and users’ anthropometrics and therefore calls for a review of the policies for classroom furniture design in Nigeria, if at all any policy exists.

Validation of Two Instruments for the Correct Allocation of School Furniture in Secondary Schools to Prevent Back Pain

BACKGROUND

Back pain is common in secondary school students. If we adjust the school furniture to the anthropometric characteristics of the pupils, we will improve their posture and reduce back pain. There is a high degree of mismatch between the furniture used by students and that which should be used. The objectives of this research are to discover the degree of mismatch and validate two instruments that allow a correct allocation of the furniture.

METHODS

The selected sample was 132 secondary students (14.08 ± 1.10 years). An anthropometer was used to determine the ideal height of the chair and table; data were taken from body segments. The recorded values were compared with those obtained by the two measurement instruments to be validated. Inter-measurer and intra-measurer reliability and validation were performed using t-tests and Pearson's coefficient, respectively. Different analysis techniques were used: descriptive, one-way ANOVA, t-test, and effect size. The established level of significance was ρ < 0.05.

RESULTS

The mismatch between the anthropometric dimensions of the students and the existing furniture in the classrooms was 98.5 % for the chairs and 100 % for the tables. The correlational analysis of the instruments to be validated shows an r = 0.993 in the chair and r = 0.996 in the table.

CONCLUSIONS

There is a high degree of mismatch between the furniture and the anthropometric characteristics of the students. The proposed furniture allocation instruments are adequate.
