Together with the deterioration of mental health there was also evidence for the worsening of general health, particularly in vulnerable groups, as reported by Kentikelenis et al. . As for the perceived health status, the percentage of people who assessed their health at the level of "good" to "very good" decreased from 75.5% in 2009 to 74.1% in 2013, whereas the corresponding proportion for the assessment at the level of "bad" to "very bad" increased from 9.7% to 10.4% during the same period . A study from Zavras et al.  verified relevant findings from previous studies which have shown that better levels of self-rated health are positively associated with income and education, the two variables that mostly characterize the socio-economic status of the population. At the same time the association was also found -as expected- to be negative with unemployment, the existence of chronic disease and age. In the same vein another study of Yfantopoulos et al.  reported that the economic crisis has also led to an aggravated level of general and oral health in Greece. The study identified statistically significant oral health inequalities among the socio-economic groups with the aged, the less educated and those confronting financial difficulties to be associated with lower levels of oral health.
