Nutrients Intake, Zinc Status and Health Risk Factors in Elderly Korean Women as Evaluated by the Nutrition Screening Inistiative (NSI) Checklist: Jin Sook Yoon, Junghyun Lee; Korean J Community Nutr 2002;7(4):539-547. Published online August 31, 2002

Abstract PDF: The purpose of this study was to investigate whether the health status as determined by a self-assessment checklist was related to the nutritional status of elderly Korean women. We interviewed 59 female subjects living in the Daegu area aged over 55 years. Information on their dietary intake on two consecutive days was collected by the 24-hour Recall Method. Their body compositions were measured using a Bio-electrical Impedence Fatness Analyzer. Their zinc status was evaluated according to their dietary zinc intake and urinary zinc excretion in urine samples collected for 24 hours. Their heath status was determined by a NSI Checklist. While 50.9% of the total subjects belonged to a moderate nutritional risk group, 23.7% of the subjects were at a high nutritional risk. It appeared that only 25.4% of the subjects were evaluated as being healthy. Therefore, the overall nutritional health status of the elderly females belonged to the moderate nutritional risk group. Except for vitamin C, the average daily nutrient intake of the subjects was below the level of the recommended dietary allowances (RDA) for Koreans. The lower the nutritional health score, the better was their dietary intake of energy (p < .05), protein (p < .001), and zinc (p < .01). A positive relationship between their nutritional health score and body fat ratio was also observed (p < .05). Therefore, we suggest that the NSI Checklist could be used as a practical screening tool at the beginning of nutritional surveillance of the elderly in the community.

Zine Status of Adult Female in the Taegu Region as Assessed by Dietary Intake and Urinary Excretion: Hyun Mee Oh, Jin Sook Yoon; Korean J Community Nutr 1997;2(1):52-62. Published online February 28, 1997

Abstract PDF: This study was intended to examine the zinc status of free-living adult women living in the Taegu region. Zine intake of 102 female subjects was measured by food frequency method for 3 consecutive days. Urinary zine was assessed from urine samples collected fir twenty four hours. Average dietary zinc intake of adult female subjects using food record was 5.9+/-1.8 mg which was 49% of Korean RDA. When zine intake by frequency method was higher than by food record. Average urinary zine intake by frequency method was higher than that by food record. Thus, it appeared that zinc intake by frequency method was higher than that by food record. Average urinary zinc excretion of 102 adult female subjects was 0.28+/-0.16 mg, which belonged to marginal zinc deficiency range. Fifty nine of 102 subjects showed marginal zinc deficiency as assessed by urinary zinc excretion. If we compare the zinc status of adult female subjects by age group, zinc intake in the 50s was significantly higher than any other age groups. However, there were no significant differences in zinc status according to BMI groups and BMI groups. Significant correlations were found between zinc intake and energy, protein, carbohydrate and fat intake. Based on dietary zinc intake and urinary zinc, we concluded that zinc status of adult female living in the Taegu region is marginally deficient.
