Data for: Cognitive impairment and the association between frailty and functional deficits are linked to abdominal obesity in the elderly: effect of gender

This file includes the data collected in the original latest representative national survey of the Israeli elderly conducted in 2005-2006. Several values were deleted because of their irrelevance while others were formed on the basis of the available data (such as co-morbidities, estimated frailty status, obesity states and others). Pay attention - data on 45 subjects were deleted from this file due to potential report bias (their cognitive score, assessed by Mini-mental state examination were lower than 17 - a clear indication for risk to cognitive dysfunction). Also, attached the original code-book of the survey describing the different variables collected in the survey, their measurement level and the full description of the question and its answers.
