Abstract:
This study was performed to investigate how milk supplementation can benefit the elderly by increasing bone density but possibly harming the iron status concomitantly. Forty one elderly subjects over 65 years of age(male : 9, female : 32) participated. All subjects were apparently healthy, home staying and attending meal service for lunch at the welfare center. They were from low income area of Puchon city. One cup of milk per day was served for 10 months. The mean intake of calcium was significantly increased for females after milk supplementation. Males showed significantly increased means of triceps skinfold thickness, suprailiac skinfold thickness and waist circumference. Females showed significantly increased measurements fo three kinds of skinfold thickness, waist circumference, and hip circumference. There were no significant change in the mean bone density of lumbar spine(L2~L4), femoral neck, ward's triangle and torchanter, but the proportion of osteopenia estimated by the T score of lumbar spine bone density was lowered from 50.0% to 34.6% for females. The mean Hb level was significantly for males. The proportion of anemia estimated by Hb(<12g/dl), Hct(<36%) and serum ferritin(<15mg/ml) were increased from 17.2% to 51.7%, from 20.7% to 44.8% and from 10.3% to 17.2%, respectively for females. It looks like milk supplementation can effect the intakes of several nutrients considered to be commonly deficient in the Korean diet fo elderly people, increase some anthropometric measurements, and decrease the proportion of osteopenia. However it can have adverse effects on iron status of females.
