In our study, we found that care burden increases by decreasing level of education. Results of the study by Aydın et al. (14) published in 2009 are consistent with our study that lower educational level increases care burden. However, in another study done in Nigeria in 2006 by Ukpong, it was concluded that higher number of years of education increases care burden. This was interpreted as well-educated person leaving his/her working environment, spending more time with his/her spouse and higher responsibility to financially support the patient (15). These inconsistent results may be due to differences at study designs and sample sizes but also be interpreted as intercultural differences which educational level may arise due to different social consequences and life styles.
