SERUM MAGNESIUM AND BONE HEALTH: A STUDY OF THE ELDERLY NUTRITION AND HEALTH SURVEY IN TAIWAN 1999

We analyzed data from the Elderly Nutrition and Health Survey in Taiwan 1999. We chose this dataset as it has data on both serum Mg levels and bone health. Among participants who had blood samples obtained (N=1,509), 210 older adults had reported fracture(s). Variables included in our linear regression models for BUA were age, sex, blood levels of hemoglobin, albumin, and creatinine. For logistic regression models for self-reported fracture, BUA measurement was included in addition to the above covariates. Our study revealed that self-reported fracture cases (N=210, female 56%, mean age 72.6 ± 6.2) and controls (N=1,352, female 47%, mean age 71.8 ± 5.2) had similar mean serum Mg levels (2.20 ± 0.19 vs. 2.18 ± 0.19 mg/dL). Fracture cases had significantly lower mean BUA compared to controls (54 ± 21 vs. 61 ± 19, p
