According to the Spearman test, a significant direct correlation was observed between physical health status and social functioning (P <0.001), physical health status and depression (P = 0.011), anxiety/insomnia status and social functioning (P = 0.026) and also depression and social functioning (P = 0.034)
(Table 2).
Among participants, there were 4 illiterate people, 9 primary educated, 11 middle school educated, 12 diploma graduated and 7 higher level educated. The highest scores of psychological status, physical condition, anxiety/insomnia and social functioning status were related to illiterate people, while depression had a higher score among people with diploma.
Discussion
This study aimed to evaluate the psychological status of HNC patients with hyposalivation due to radiotherapy. In this study, the average psychological status was reported to be 27.50. According to Ebrahimi et al.'s study, the clinical cut-off point for the GHQ-28 questionnaire in Iran was 24, so cancer and its complications overshadowed the psychological status of the subjects in this study
(16).
In different studies, different questionnaires such as mental component summary (MCS), Hospital anxiety and depression scale, PSQI, ESS, hospital anxiety and depression scale (HADS), Taiwanese depression questionnaire (THQ) and also clinical interview has been used for assessing the psychological status of HNC patients
(5, 18-22).
In a study conducted by Nielson et al., the prevalence of depression was initially 15%, increased to 29% by 3 weeks after treatment, and decreased to 8% at the end of 18 months. The prevalence of anxiety was 20% at the beginning and reached 17% 3 weeks after treatment and 22% at the end of 18 months
(19). In the Lopez-Jornet study, hyposalivation was significantly associated with depression
(5). In the study of Pelland et al., 345 patients (25.6%) had moderate to severe anxiety and 120 patients (8.9%) had moderate to severe depression
(20). In the study conducted by Lee et al., 13 patients (14%) had depression after 6 months, which had increased compared to the beginning of treatment (8.5%)
(21). In the study of Wu et al., Pre-treatment anxiety rate was high which decreased over time (from 27.3% to 6.4% and then 3.3%) and the rate of pre-treatment depression was 8.5% and then decreased to 24.5% and 14%, respectively, and hyposalivation was significantly associated with depression
(22). In the study of Astrup GL et al., mental health status in HNC patients decreased and after 6 months, returned to the previous state
(18). In the study of Nikoloudi et al., Depression and anxiety in HNC patients significantly increased after radiotherapy
(23).
This significant increase between radiation-induced hyposalivation and depression was also observed in the present study. Comparison between that study and ours showed that cancer individually makes no significant effect on psychological, but the side effects of cancer and radiotherapy such as hyposalivation can result in depression and mental illness. In most studies, the rate of hyposalivation was closely related to the psychological status, however after a long period and partial return for saliva production ability, psychological status and its components have been improved after 1 year of radiotherapy and approached to primary state
(5, 19, 21, 22).
In the present study, as age increased, psychological status and its components such as anxiety, insomnia, physical health problems and social functioning issues increased. These results were in contrast to Nielson et al.'s study, in which younger patients were more anxious
(19).
In Malekian et al.'s study, depression rate was higher in 50-65 years old patients in comparison with other age groups
(24). In the study of Rajabizadeh et al., the prevalence of depression was significantly associated with ages over 45 years
(25).
It is very difficult to diagnose depressive mood indicators in the elderly; since the symptoms of depression in the elderly vary from those in adolescence. These differences can be originated from depressing experiences such as heartburn, painful illness, or cognitive impairment such as memory loss. Depression in the elderly is the second disability after physical causes. People who have had a history of depression during their lifetime show more depression in older ages
(26).
In this study, the psychological status average among men and women was not statistically significant. Other components (depression, social functioning, anxiety/insomnia, and physical health) were not statistically significant despite being lower in men. In the study of Malekian et al., despite the higher prevalence of anxiety and depression in women, no statistically significant differences were observed between the two groups
(24). In the study of Rajabizadeh et al., No significant relationship was observed between gender, severity and prevalence of depression
(25).
Also in the study of Astrup GL et al., There was no significant difference between mental health and gender (P = 0.348)
(18). In the study conducted by Linden et al., the prevalence of anxiety in women was significantly higher (P <0.001) that can be explained by women's higher tendency to express emotions
(27). The study by Pelland et al. did not agree with the results of our study in this regard
(20).
Social anxiety is the clinically significant anxiety due to social or functional situations that often leads to avoidant behavior. Epidemiological reports have estimated that women more likely develop social anxiety disorders, like other anxiety disorders; but few studies equate this ratio. The reason for this discrepancy may be the difference in diagnostic characteristics and examination indexes. In other words, this heterogeneity in the relationship between social anxiety and gender is always seen in the articles. Researchers have found that masculinity is negatively related to anxiety. Masculinity is negatively related to general levels of fear and panic such as fear of failure and criticism and fear of the unknown and medical fear; while there is a direct relationship between femininity and anxiety as well as sensitivity to anxiety symptoms. As a result, gender role is a mediator between femininity and sensitivity to anxiety symptoms
(28).
Among the patients of this study, the highest scores of psychological status, physical condition, anxiety/insomnia and social functioning were in illiterate individuals, while the highest scores of depression were in those with diploma degree. In the study of Naseri et al, patients with higher education had higher rates of depression
(29).
In the study of Rajabizadeh et al., a significant relationship was observed between the level of education and depression of oncology patients, so with increasing education, the severity of depression decreased (P <0.001)
(25). There was a significant relationship between the rate of depression in women with breast cancer and the level of education (P = 0.001)
(28). In the study of WU et al., no significant relationship between anxiety and depression and education level and other demographic characteristics was found
(22).
Conclusion
To justify the results of this study, it can be stated that an increase in a person's level of education increases access to information resources and raises the level of knowledge and awareness about cancer and ways to treat it, and despite positive results, this can also make an individual sad and depressed.
The limitation of the present study was difficulty in assessing patients due to their poor physical condition. In this study, only the mental status of HNC patients was evaluated. It is recommended to consider the psychological status of patients with various head and neck cancers treatment.
