A new study has revealed that cancer patients who are malnourished experience significantly greater levels of psychological distress than those who are more adequately nourished.
For the study, Dr Shafia Amdouni, from the Cancer Nutrition Rehabilitation Program at Canada's McGill University Health Center, and colleagues set out to examine the relationship between malnutrition and psychological distress in patients who were taking part in a cancer nutrition rehabilitation program.
AdvertisementThey looked at 213 patients with advanced cancer, asking them to assess their own nutrition status and their distress.
Nutrition was measured using a patient-generated subjective global assessment, which calculates a grouping of nutritional scores after combining information from food intake, weight change, nutrition-related symptoms, and performance status and categorizes patients into three distinctive classes of nutritional status.
Distress was measured using a 'distress thermometer', a self-reported measure using an 11-point scale from 0 (no distress) to 10 (extreme distress).
The researchers found that the score on the distress thermometer was positively correlated with the total score of the patient-generated subjective global assessment. The higher the distress, the worse the patient's nutrition status.
"Our data suggest that nutrition status may contribute to the level of distress in patients with cancer. Evaluation of the nutrition status should be included in the evaluation of distress experienced by these patients," Amdouni said.
The researchers said that ideally, patients should be seen by a clinical nutritionist or a clinical dietician.
The new results have been reported at the European Society for Medical Oncology's Symposium on Cancer and Nutrition.
