The findings showed that there is a direct and negative correlation between the two lifestyle variables and depression, and among the different lifestyle items, social support and exercise components are more strongly correlated with depression. From a psychological perspective, people's lifestyle plays an important role in their mental and social health. In this regard, in a similar study conducted by Njogu et al., it was reported that stress, anxiety, and depression are side effects of treatment for infertile women (
19). Also, Alnaeem et al. evaluated anxiety and depression in infertile women with polycystic ovary syndrome and its correlation with lifestyle; the findings of the aforementioned study showed that two-thirds of the women studied had depression, anxiety, and stress, which was correlated with their age, weight, diet, and lifestyle (
20).
Based on the findings of the present study, there is a direct and negative relationship between the social health variable and depression. Although all social health components have an impact on depression, this correlation was slightly stronger for the cohesion and participation components and weaker for the flourishing component. Bedaso et al. reported that pregnancy is a time of profound physical and emotional changes, as well as an increased risk of mental illness. They believe that strengthening social support as one of the components of social health is a common factor for reducing mental health risks. Therefore, policymakers and those working in the field of maternity care should consider developing targeted social support programs with the aim of helping to reduce mental health problems among pregnant women (
21). In a study conducted on infertile women, Zarif Golbar Yazdi et al. concluded that both women and men are affected emotionally, physically, and socially by infertility, but women are in a more difficult position compared to men (
22). The findings of the study by Tafvizi Zavareh et al. showed that there is an inverse and significant relationship between mental health statuses and perceived social support score, which is consistent with the findings of the present study (
23).
According to the findings of this study, there was significant and negative correlation between depression and components of marital satisfaction in infertile women. Infertility can cause disruption in the quality of marital relationships, fear of separation, decreased self-confidence, and feelings of rejection from family and society. The combination of these factors can make an individual susceptible to mental and psychological diseases such as depression and anxiety, and lack of enjoyment of marriage. Fazaeli et al. emphasized in their study that marital dissatisfaction is associated with the occurrence of psychological problems including depression and stress (
24). The mental and social health of individuals is influenced by a range of psychological, sociological, and demographic factors. In Iran, despite the existing deficiencies, especially in deprived areas, appropriate steps have been taken for the physical health of individuals. Sometimes, in Iran, the mental and social dimensions of health are neglected, and this neglect of the social aspect of health increases the vulnerability of individuals (
11,
22). In various studies, the correlation between depression and infertility with marital satisfaction has been evaluated as intertwined factors. Mansouri et al. believe that infertility, as one of the stressors, can create important problems in couples' relationships, including reduced communication with each other, difficulties in sexual activity, and emotional and mental disorders (
25).
Also, based on the findings of this study, the lifestyle variable had an indirect effect on depression through the mediation of marital satisfaction. To explain this finding, it can be said that common factors in marital satisfaction and lifestyle lead to life satisfaction and improve mental health. Marital satisfaction is actually positive and enjoyable attitude that makes couples satisfied with various aspects of life, including opportunities, decision-making, income, lifestyle, sexual relationship, etc. In addition, marital satisfaction creates feeling of happiness that has significant impact on the mental health of couples.
The findings of the present study showed that the social health variable had an indirect effect on depression through the mediation of marital satisfaction. Perhaps the social dimension of health is the most complex and at the same time the most controversial aspect of health. Also, the social health of individuals is one of the factors affecting the level of marital satisfaction, which is supported by which family relationships can be understood and predicted. People with appropriate social health and high marital satisfaction do not feel isolated and feel calm and trusting with their family.
Based on the results of the present study, the main hypothesis of this study was confirmed and it can be stated that depression in infertile women can be predicted based on lifestyle and social health components with the mediation of marital satisfaction. Theories of scientists and psychologists as well as similar studies also strengthen the validity of this hypothesis.
5.1. Limitations
Limitations of the study include the following:
- Since the questionnaires were online, the researchers could not track and control whether the participants understood the questions and responded appropriately.
- Due to the COVID-19 pandemic and the decrease in the number of visits to the infertility clinic, sampling was conducted over longer period of time.
- Environmental stressors such as the COVID-19 emergency were not controllable by the researcher.
- Stressors resulting from difficult infertility treatments, disappointment, and family problems were not controllable by the researcher.
5.2. Conclusions
Based on the findings of the present study, it can be said that the three main variables including social health, lifestyle and marital satisfaction have indirect (negative) and significant relationship with the depression variable. While, there was direct (positive) and significant correlation between the three main variables mentioned above with each other in two-by-two manner. Also, based on the findings of this study, the lifestyle and social health variables had an indirect effect on depression through the mediation of marital satisfaction. Based on the results of the present study, the main hypothesis of this study was confirmed and it can be stated that depression in infertile women can be predicted based on the components of lifestyle and social health through the mediation of marital satisfaction.
