For analysis, Begg and Mazumdar test at a significance level of 0.1 and the corresponding Funnel plot were used. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2).
In the review of 98 studies with a total sample size of 79976, the prevalence of malnutrition in the world's elderly was obtained as 18.6 % (95 % confidence interval: 16.4-21.1 %), so that the highest prevalence of malnutrition was in the elderly of Africa with 35.7 %, followed by the America with 20.3 %.
