Nutrient deficiencies such as antioxidants are common problems in elderly subjects which can result in different cancers and macular degeneration. due to it, assessment of the dietary intake of antioxidants is important to design some plans for solving this problem.


This case-control study was conducted on 152 elderlies (≥60 years) with and without health care in primary care centers in isfahan (iran). nutritional assessment was performed by expert nutritionist with the use of semi quantitative validated food frequency questionnaire (ffq). also, n4 software was used as food analyzer software. ancova test and independent t-test was used to analysis.


Mean (sd) age, weight, height and bmi were 68.7 (5.5) years, 63.5 (7.9) kg, 162.6 (7.1) cm and 24.1 (3.4) kg/m2 respectively. intake of beta carotene was significantly lower but intake of vitamin a and c were significantly higher in women under health care (pβ-carotene=0.015; pvita=0.003; pvitc=0.045). also, selenium intake was significantly higher in men under health care (pse=0.046). overall, total intake of energy, vitamin e and selenium were significantly higher and beta carotene intake was significantly lower in elderlies with health cares than the control group (penergy=0.038; pse=0.010; pvite=0.004; pβ-carotene=0.014).


Current study indicated that nutritional care can improve some antioxidants in primary care centers. findings showed that the intake of energy, vitamin e and selenium were high but beta carotene intake was low among elderlies under health care.
