Diketahui bahwa kekuatan otot dasar panggul dan taksiran berat janin memiliki perbedaan bermakna dengan inkontinensia urin tekanan p = 0,002, < 0,001, secara berurutan . Uji multivariat menunjukkan bahwa kekuatan otot dasar le; 25,5 cmH2O panggul dan TBJ ge; 3.100 gram paling mempengaruhi kejadian inkontinensia urin tekanan OR = 2,52, p= 0,021 dan OR = 3,34, p= 0,001, secara berurutan . Uji probabilitas menunjukkan bahwa apabila TBJ >3.100 gram dan kekuatan otot dasar panggul
