Objective: Children’s healthy nutrition is a priority for mothers. The mother\'s eating behavior affects her feeding behavior. The aim of this study was to investigate the tendency of healthy eating obsession of mothers parenting with chronic or acute diseases.

Material and Methods: The study was conducted with mothers of children hospitalized due to chronic or acute illness. ORTO-11 scale was given to mothers and they were asked to complete it. The ORTO-11 scale measures healthy eating obsession (orthorexic eating behavior). The low score on the scale indicates a tendency to obsess over healthy eating.

Results: There was no significant difference between the ORTO-11 scores of the mothers of children with chronic and acute disease (p> 0.05). The score of the mothers of children with chronic illness who perceived their income level good was significantly lower than those who perceived low (p <0.05). ORTO-11 scores of mothers with good income or working were significantly lower than those who don’t work or have low income (p <0.05). There was no significant relationship between the duration of illness, age, weight and height percentiles of the children and ORTO-11 scores (p> 0.05).

Conclusion: The obsession with healthy eating was found to be similar in these two groups of mothers having a diseased child hospitalized due to chronic or acute illness. It was observed that income level of mothers influenced the tendency to obsess over healthy eating regardless of the children\'s acute or chronic illness.
