Data processed univariate and bivariate with the Spearman test.Results: There was an effect of schoolbag-weights and musculoskeletal complaints among high-school students in Jakarta, Indonesia. Spearman correlation analysis results, got p=0.000 with r=0.225, which means there is a weak correlation between schoolbag-weights with musculoskeletal complaints.

Variabel bebas adalah berat tas sedangkan variabel terikat adalah MSDs. Pengambilan data dengan pengisian kuesioner. Data diolah secara univariat dan bivariat dengan uji korelasi spearman. Hasil: Didapatkan korelasi antara berat tas dengan musculoskeletal disorder. Hasil Analisis Korelasi Spearman antara berat tas dengan keluhan nyeri otot, didapatkan nilai p=0.000 dengan nilai r=0.225 yang artinya terdapat korelasi yang lemah antara berat tas dengan keluhan nyeri otot. Arah korelasi positif menunjukkan bahwa semakin berat beban tas maka keluhan nyeri otot makin tinggi, begitu juga sebaliknya. Simpulan: Berat beban tas berkorelasi dengan keluhan Musculoskeletal disorders (MSDs).
