The relationship of ecological factors to the dietary intakes of 166 elderly aged 65 years and over (53male, il3female) in Pygag-taek area. The ecological data was obtained by interview using questionnaires and dietary survey was done by 24-hour recall method and interview during the June 10 to July 10, 1986.

The 24.5/31.9(male/female) %, 37.7/59.3% and 54.7/47.8% of the subjects took protein, calcium and vitamin A below two-third of RDA. Male had higher intakes of calcium (p. <05), iron (p<. 01), riboflavin (p<. 05) and niacin (p<. 05) than female.
Ecological factors showed significant correlations with nutrient, intakes to some degree (r= 156~410). The male subjects´ nutrient intakes were positively influenced by socioeconomic status such as pocket money and education level, while female were positively influenced by psychological factors including self-consciousness of health.
