In the study, anthropometric measurements, body compositions, nutrient intakes, and biochemical markers were used to validate the questionnaire. The studied population consisted of 245 group-living elderly sampled from Yi-Yuan and Tsui-Po elderly centers. The average age of surveyed subjects was 79.4 ± 5.1 years old. Most of the male elderly were veterans, teachers or civil servants, and female elderly were housekeepers mostly. They had higher education levels compared with their contemporaries of community dwelling. Thirty-one percent of studied population were overweight, and the obese rate was 23 %. The average levels of blood biochemical markers were at normal ranges for both sexes. Except serum cholesterol of female elderly. Cataract was the highest prevalent chronic diseases among surveyed subjects, followed by hypertension, arthritis, coronary heart disease and hemorrhoids. Daily energy intake of male elderly was 1821.4 ± 483.7 kcal and it was 1358.7 ± 394.2 kcal for female. Both male and female elderly''s protein intakes（male：70.1 ± 18.1 g, female：55.5 ± 13.6 g）met the recommendation of Dietary Reference Intakes ( DRI’s ). Besides vitamin E, vitamin B6 and calcium intakes of both sexes, female’s energy, vitamin B12 intakes were below DRI’s. Three factors with 7 nutrition related questions were screened out for the nutrition screening questionnaire by factor analysis. Internal reliability and correlation analysis showed that the shortened nutrition screening questionnaire ( SNSQ ) had good internal consistency. Positive correlations were found between SNSQ and body mass index, mid arm circumference and hemoglobin. At the cut-off point of 9.5, the sensitivity and specificity of shortened nutrition screening questionnaire ( SNSQ ) were highest. It showed that the shortened nutrition screening questionnaire ( SNSQ ) has good validity and reliability.
