Abstract
Summary Objective The aim of the current study was to assess the zinc status (intake and level) and its relationship to cognitive impairment among men and women aged 65 years and above in Riyadh, Saudi Arabia. Methods A cross-sectional single-center study was conducted in 400 participants (200 men and 200 women) aged 65 years and above. They were randomly chosen in the primary care centers in Riyadh. The impaired cognitive functions were measured using the Abbreviated Mental Test Score (AMTS). Plasma zinc concentration was analyzed using an atomic absorption spectrophotometer. Results The mean plasma zinc concentration was 70 ± 2.34 μg/dL, 36% of studied participants had zinc deficiency. Zinc deficiency was significant more frequent in women than men (45% versus 27%, respectively) (p Conclusion Our study indicates that zinc status may be associated with cognitive impairment measured by AMTS in the Saudi elderly population.
