1. Taiwan DRI (dietary reference intakes, DRI) of magnesium for health individuals above 19 years of age is 360 mg/d for males and 315 mg/d for females.
2. Categorical variables were analyzed according to frequency distribution and expressed in number and percentages [n (%)].
3. Continuous variables were presented as mean values and standard deviation (Mean ± SD).
