Medians and interquartile intervals or number and percentage are shown for numerical or categorical data. High BMI, high waist circumference, high systolic/diastolic blood pressure, high HbA1c, low HDL cholesterol, high LDL cholesterol and high triglyceride were defined by ≥27 kg/m2, ≥85 cm (men) or 90 cm (women), ≥130/85 mmHg, ≥5.7%, ≤1.03 mmol/L (40 mg/dL), ≥3.62 mmol/L (140 mg/dL) and ≥1.69 mmol/L (150 mg/dL), respectively, according to the previous reports or current guidelines for the Japanese population.
n.s., not significant.
a Mann–Whitney U or Pearson chi-square tests were performed to compare numerical data or proportions between the tsunami and radiation groups, respectively.
BMI, body mass index; HDL, high-density lipoprotein; LDL, low-density lipoprotein.
