Nutritional status in elderly population in kibbutzim
Summary
Elderly Israelis show nutritional deficiencies in ascorbic acid, hemoglobin, iron, carotene, retinol, thiamin, and riboflavin. However, pyridoxine levels were adequate in this study population.
Area of Science:
- Gerontology
- Human Nutrition
- Clinical Biochemistry
Background:
- Nutritional status is crucial for elderly health.
- Age-related physiological changes can impact nutrient absorption and utilization.
- Assessing micronutrient levels in older populations is essential for preventative healthcare.
Purpose of the Study:
- To evaluate the nutritional status of elderly individuals residing in Israeli Kibbutzim.
- To assess key vitamins (thiamin, riboflavin, pyridoxine, carotene, retinol, ascorbic acid) and minerals (iron, albumin).
- To identify potential nutrient deficiencies within this specific demographic.
Main Methods:
- Blood samples were collected from 59 elderly subjects (60-85 years old).
- Nutrient status was determined using enzymatic activation coefficients for thiamin, riboflavin, and pyridoxine.
- Levels of ascorbic acid, hemoglobin, plasma iron, carotene, retinol, and plasma albumin were analyzed.
Main Results:
- Deficiencies were observed in leucocyte ascorbic acid (5%), hemoglobin (18%), plasma iron (20%), plasma retinol (20%), and plasma carotene (32%).
- Thiamin deficiency was noted in 14% and riboflavin deficiency in 32% of the participants.
- No pyridoxine deficiencies were detected in the study group.
Conclusions:
- The elderly population in these Israeli Kibbutzim exhibits several significant micronutrient deficiencies.
- Riboflavin, carotene, and plasma iron status require particular attention in this demographic.
- Pyridoxine status appears adequate, but further research may be warranted.
