Note: Significant probabilities are marked in bold
PTA pure-tone average, High PTA was defined as pure tone average of the threshold at 4, and 8 kHz in the better ear; Speech PTA was defined as pure tone average of the threshold at 0.5, 1, 2, and 4 kHz in the better ear
Model 1: unadjusted model
Model 2: adjusted for BMI, marital status, living alone, monthly income, education, drinking, smoking, IPAQ, ADL, IADL, diabetes, hypertension, hyperlipidemia, and stroke
