Type 2 diabetes and depression are commonly comorbid, high-prevalence, chronic disorders. Individuals with diabetes mellitus may have concurrent mental health disorders and are shown to have poorer disease outcomes. However, the evidence for clinical correlation is still unclear. Objectives To find the prevalence of depression among patients with type 2 diabetes at King Abdullah Medical City (KAMC). Materials and methods A cross-sectional observational study was conducted at KAMC in Makkah, the Kingdom of Saudi Arabia. Study participants were 267 people with type 2 diabetes (aged between 18-70 years). Those who had preexisting depression or drank alcohol, pregnant women, and postpartum women were excluded from the study. Participants’ clinical and demographic data and depression assessment were obtained on phone through an interview and using the Arabic version of the Patient Health Questionnaire-9 (PHQ-9), respectively. Glycated hemoglobin (HbA1c) test results of participants were collected electronically. Results The participants’ mean age was 57.88 ± 8.71 years, and 64.4% were males. Only 15.4% were current smokers and 16.9% were ex-smokers. The most common medical condition was hypertension (65.2%) and the majority (92.1%) had uncontrolled HbA1c with a mean value of 8.37 ± 1.92. Among the studied patients, 73% suffered from different degrees of depression; 36%, 19.9%, 8.6%, 5.2%, and 3.4% of the participants were suffering from minimal, mild, moderate, moderately severe, and severe depression, respectively. Only neuropathy was a significant risk factor of depression (odds ratio=2.87, 95% confidence interval=1.18-6.97, p=0.02). Conclusion Depressive symptoms are common in patients with uncontrolled type 2 diabetes who also suffer from neuropathy and retinopathy. Hypertension, cardiovascular diseases, and unhealthy diet had a significant correlation with depression. Diabetes is one of the most widespread chronic diseases globally [1] . The International Diabetes Federation (IDF) estimates that 463 million people in the world have diabetes. Among these, 55 million live in the Middle East and North Africa region, and this figure is expected to reach 108 million by 2045 [1] . The Kingdom of Saudi Arabia (KSA) is one of the 21 participant countries and territories in the International Diabetes Federation Middle East and North Africa (IDF MENA) region. Approximately 18.3% of the total adult population in the KSA is diabetic [1] . The World Health Organization (WHO) states that depression is the second leading cause of loss of disability-adjusted life years [2] . Depression is a psychological disorder characterized by constant low mood, a sense of hopelessness, and several risk factors. The prevalence of depression in primary care varies between 15.3% and 22%, with a prevalence of up to 13% worldwide [3] . In KSA, the prevalence of depression ranges from 17% to 46%. Moreover, nearly 80% of primary care physicians Thus, there is a need to understand how depression and its associated factors affect people with type 2 diabetes [13] . More knowledge in this area will help to make better decisions to enhance healthcare provided to diabetic patients [13] . The present study focuses on estimating the prevalence of depression among patients with type 2 diabetes at King Abdullah Medical City (KAMC) in Makkah, KSA, and determine the associated factors. A cross-sectional observational study was carried out at KAMC in Makkah, KSA from July 2020 to January 2021. Patients with type 2 diabetes (aged between 18 and 70 years) receiving follow-up treatment at outpatient clinics in KAMC participated in the study. Those who had preexisting depression or drank alcohol, pregnant women, and postpartum women were excluded from the study. Using the WHO sample size calculator, a sample size of 385 patients was considered adequate. The final sample comprised 267 patients who agreed to participate in the study. Data were collected using a predesigned questionnaire that included two sections. The first section included items on the demographic data of patients. Data in the second section included HbA1c results of patients were collected electronically and patient responses to the Arabic version of the Patient Health Questionnaire-9 (PHQ-9) [14] were obtained via phone. The Arabic version of PHQ-9 is a sensitive but not specific screening tool for depression in comparison to clinical diagnosis. The PHQ-9 is a self-administered scale used to measure depression. Items are rated from 0 to 3, according to the increased frequency of experiencing different mental health concerns, and the total score ranges from 0 to 27. The score is interpreted as indicating no depression or minimal, mild, moderate, moderately severe, or severe depression [14, 15] . SPSS version 26 (IBM Corp, Armonk, USA) was used to analyze the data. Qualitative data were expressed as numbers and percentages, and the Chi-square test (χ2) was used to analyze relationships between variables. Quantitative data were expressed as mean and standard deviation (mean ± SD), and the Mann-Whitney U test was performed for non-parametric variables. The Mann-Whitney U test was used after testing the normality of quantitative data. The normality was tested using the one-sample Kolmogorov-Smirnov test and the value of significance was less than 0.05. So, it was considered as not normally distributed data and the nonparametric Mann-Whitney U test was used. Among the patients, 73% suffered from different degrees of depression. Figure 1 illustrates that 36%, 19.9%, 8.6%, 5.2%, and 3.4% of the patients suffered from minimal, mild, moderate, moderately severe, and severe depression, respectively. Multivariate logistic regression analysis was performed to assess the independent predictors (risk factors) of depression among patients. Only neuropathy was found to be a risk factor (odds ratio = 2.87, 95% confidence interval = 1.18-6.97, p = 0.02) ( Table 5) . Depression affects approximately one-third of people with diabetes [16] , impacting their quality of life and presenting self-management challenges. Therefore, identifying mental health problems and associated factors among diabetic patients will assist healthcare physicians in providing better healthcare for such cases. A local study has suggested that patients with diabetes should undergo periodic psychological assessment as part of their clinical evaluation [13] . The current study estimates that 73% of patients with type 2 diabetes in Makkah, KSA, suffer from depression, which is a higher number than that reported by another study in Makkah (20.68%) in 2018 [16] . This variation in prevalence could be explained by the fact that the current study was conducted in a single facility at King Abdullah Medical City, which is a tertiary specialized hospital that deals with complicated cases and referred cases from other general hospitals. While the study conducted in 2018 included patients from three different institutions (Al Noor Hospital, the diabetes center of Hera'a hospital, and the Alaziziah outpatient clinic) Additionally, differences in sample size could have played a role. The 2018 study involved patients suffering from two different types of diabetes, while this study focused only on type 2 diabetic patients, representing 90% of diabetics worldwide and in Saudi Arabia [16] . The prevalence of depression estimated in our study conforms with a study conducted in Tabuk city (78%) including 221 patients with type 2 diabetes [17] . Another study included 450 patients with type 2 diabetes attending primary healthcare centers, and the prevalence of depression was found to be 33.8% using the Depression, Anxiety and Stress Scale-21 (DASS-21) questionnaire [9] . The DASS-21 has a similar utility as the PHQ-9 in measuring the severity of depression symptoms [18] . Another study used the Hospital Anxiety and Depression Scale (HADS-D) and found 34.8% of 300 patients with type 2 diabetes in a hospital in Unaiza, Qassim region suffering from depression [19] . In another study conducted in the Eastern Province, KSA in 2013, depression prevalence was 49.6% [20] . The current study reported a higher prevalence of depression among diabetic patients than the studies conducted in Jazan (20.6%) [21] and Arar (37%) [5] that were both conducted in primary healthcare centers as well. A national-level meta-analytic study conducted in 2021 found the prevalence of depression was 38.06% in patients with type 2 diabetes (95% confidence interval = 30.84-45.28) [22] . Another point that could explain this variation in the result is the fact that this study was conducted during the COVID-19 pandemic, which had a huge psychological impact on the general population worldwide, leading to an increase in the global estimated prevalence of depression in general. Furthermore, depression was associated with the prevalence of diabetes-related complications, which aligns with the findings of other studies. Among these complications, only peripheral neuropathy was found to be significantly associated with depression. This finding confirms a study conducted at the primary healthcare centers in Qatif in 2011 [23] . Our findings demonstrated a significant association between depression and cardiovascular disease. Previous studies have also reported similar results [24] . According to our findings, physical activity lowers the likelihood of acquiring a psychiatric condition, such as depression, and type 2 diabetic patients who are physically inactive have a higher risk of depression, which is consistent with the findings of a study conducted in primary healthcare centers in Jazan in 2020 [25] . Patients with hypertension and ischemic heart disease were found to have a higher risk of developing depression than those with other comorbidities [25] . Increased diabetes duration is linked to a higher risk of complications and healthcare costs [26] . Neuropathy and retinopathy predicted a higher risk of depression than other diabetes-related complications during a study conducted in Arar [5] . The majority of our sample was male (64.4%), and our study concluded that there is no association between females and depression, unlike previous studies [27] . As 92.1% of our sample had uncontrolled HbA1c, we could not assess the association between HbA1c and depression. A link between poor glycemic control and depression has been discovered in several cross-sectional studies [28] . This study has a few limitations. A cross-sectional design is insufficient for assessing the direction of the relationship between depression and diabetes in patients. Additionally, a single-center, hospital-based investigation with a randomly selected small sample size during a particular period of time does not provide reliable data about the prevalence of depression among patients with type 2 diabetes. Also, the fact that this study was conducted during the COVID-19 pandemic period could affect the results. Depression symptoms are common in patients with uncontrolled type 2 diabetes who also suffer from neuropathy and retinopathy. Hypertension, cardiovascular diseases, and unhealthy diet also had a significant correlation with depression. We advise that patients with uncontrolled type 2 diabetes who have these diabetes-related complications be regularly screened for depression. Furthermore, most patients with uncontrolled type 2 diabetes were found to suffer from neuropathy; therefore, we recommend proper screening for depression among diabetic patients with neuropathy and early screening for neuropathy in type 2 diabetic patients to prevent depression because of late management of these complications.
