Introduction

The medical comorbidity of psychiatric patients is a topic of increasing significance and there is a need to indicate as how common is the comorbidity [1]. The possible reasons for this increased comorbidity may include a genetic relationship between the mental and medical disorders [2]. Both conventional and novel antipsychotic agents are associated with weight gain [3]. Patients with schizophrenia treated with atypical antipsychotics had a moderately increased risk of DM [4]. The use of psychotropics contributes to weight gain, which is associated with diabetes and hypertension. Smoking in psychiatric patients contributes to heart diseases. Physical inactivity contributes to hypertension and heart disease. Those with a comorbid substance use disorder had the highest risk for some medical disorders e.g. heart diseases [5]. WHO has suggested that persons with mental disorders have a right to healthcare comparable to that received by the general population [6]. Not only medical illnesses cause cognitive impairment, but cognitive impairment may also lead to the onset and exacerbation of these medical comorbidities among patients with schizophrenia [7]. Patients with schizophrenia have high rates of under-diagnosed, under-treated and under-documented medical problems [8]. Medical illness complicates the treatment of mental illness, and patients with severe mental illness die at an earlier age from physical health problems than do those without mental illness [9]. Elderly psychiatric patients and patients with organic mental disorders e.g. dementia present the greatest risk of comorbid physical illness, with high prevalence rates of such illnesses [10]. 72% of psychiatric inpatients have medical comorbidity [11]. Prevalence of hypertension, diabetes mellitus and cardiovascular diseases among psychiatric patients are 10.2%, 7.36% and 8.77% respectively [5]. The overall prevalence of diabetes and impaired glucose tolerance in schizophrenic patients was 16.0% and 30.9%, respectively [12]. The prevalence of diabetes mellitus in schizophrenia patients in different age groups (15-25: 2%; 25-35: 3.2%; 35-45: 6.1%; 45-55: 12.7%; 44-65: 25%) [13]. Cardiovascular mortality was 6.6 times higher among psychiatric patients than the general population. Cardiovascular mortality in Schizophrenia increased from 1976 to 1995, with the greatest increase in Standardized Mortality Ratios in men from 1991 to 1995 [14]. Prevalence of diabetes mellitus in bipolar affective disorders is 19%. Prevalence of cardiovascular diseases in bipolar affective disorders is 44%. Prevalence of hypertensions in schizophrenia is 35% [15]. Depressed individuals have a 60% increased risk of developing diabetes [16]. 13.3% of mental retardation cases have both a psychiatric as well as medical illness. Psychiatric comorbidity presents in 56.67% of mental retardation patients. 35.0% of mental retardation patients have medical disease comorbidity. 41.18% of mentally-retarded patients with a psychiatric disorder had mild mental retardation and 29.41% of mentally-retarded patients had severe to profound mental retardation, whereas 23.81% of mentally-retarded patients with a medical disease had mild mental retardation and 57.14% had severe to profound mental retardation. In mentally-retarded patients who had a psychiatric comorbidity, a medical disease was present in 23.53% patients, as compared to 50.0% patients in those who had no psychiatric comorbidity [17]. I did not find researches in Saudi Arabia shed the light on the comorbidity between mental and medical illnesses. Therefore, there a need for such studies in Saudi Arabia.

Objectives

This study aimed to assess the pattern of three medical illnesses; diabetes mellitus, heart diseases and hypertension among chronic psychiatric inpatients in Taif mental hospital, Taif, Saudi Arabia.

Methodology

Study design

A cross-sectional study was conducted at Taif mental hospital, April and May 2008, in Taif city, Saudi Arabia among the chronic psychiatric inpatients by a retrospective chart review.

Study population

The study population consists of all chronically admitted psychiatric patients in Taif mental hospital who had been admitted for at least one year and with no plan for future discharge (permanent), with or without medical condition. That means they are permanent to stay in the hospital without discharge due to different reasons such as no social support or forensic issues (homicide).

Sampling procedure

465 patients who fulfill the criteria were included in this study.

Data collection

Data were collected from chart reviews to complete the pre-designed questionnaire that includes information concerning demographic data, psychiatric diagnosis and medical comorbidity. The principal investigator conducted the data collection because nobody agreed to help him and no financial support for this effort.

Analysis plan

The Epi-Info was used for data entry and analysis. The data were analyzed to estimate the prevalence of each psychiatric disorder in addition to the prevalence medical comorbidities and their distribution among them. The frequencies and distribution of mental illnesses by gender and age group were calculated. Psychiatric disorders are categorized into three categories; schizophrenia, mental retardation and other psychiatric diagnoses. I combined other psychiatric diagnoses into one group to make figures significant because some disorders have very small percentage.

Ethics

Ethical and administrative approvals were obtained from field epidemiology training program and the Ministry of Health committee. Regarding consent; no consent was required from the patients because the data were collected from medical files. The study involved no risk to the subjects. The waiver or alteration of consent did not adversely affect the rights and welfare of the subjects. Whenever appropriate, the subjects will be provided with additional pertinent information after participation. Regarding confidentiality; the confidentiality of personal data was maintained. The information was gathered and recorded by the principal investigator. No other individuals participated in data collection or had access to the medical files except the supervisor. Names and file numbers did not appear in the study. Thus, the subjects could not be identified. Codes were given to the files (e.g., #10 in the sample or the last 3 digits of the file number).

Results

A total of 465 permanent psychiatric inpatients in Taif mental hospital during the study period included in the study. Every patient had been admitted for at least one year.

Socio-demographic characteristics

All psychiatric inpatients were distributed over 13 wards (4 female wards and 9 male wards, including two forensic wards). There are 357 male patients and 108 female patients. There are 28 patients within ≥30 years age group, 91 within 31-40 years, 171 within 41-50 years, 101 within 51-60 years, 53 within 61-70 years and 21 over 70 years age groups (Tables 1 and 2).

Medical illness distribution by psychiatric diagnoses

The pattern of the three medical comorbidities among the psychiatric inpatients with comorbidity was as follows: (82.9%) present in schizophrenia, (12.9%) in mental retardation and (4.2%) in other psychiatric mental disorders. Medical illnesses are 49.3% heart diseases, 25% hypertension and 25.7% diabetes mellitus. When the pattern of medical comorbidities was described by psychiatric diagnoses, it was found that: among schizophrenic patients (51.7%) with heart diseases, (20.7%) with hypertension and (27.6%) with diabetes mellitus. Among mentally retarded patients (38.9%) are with heart diseases, (50%) with hypertension and (11.1%) with diabetes mellitus. Among those patients are with other mental illnesses (33.3%) with heart diseases, (33.3%) with hypertension and (33.3%) with diabetes mellitus (Table 5).

Discussion

It is noticed that, the prevalence of the three medical illnesses among chronic psychiatric inpatients represents a high figure 30.1% but less than that of other studies [11,17]. This difference may be due to that, our study concentrated only on three groups of medical illnesses but other study considered all medical illnesses. They are higher among schizophrenic patients (82.9%) than those in mental retardation and other psychiatric diagnoses [8]. Heart diseases prevalence is the highest among the three medical illnesses. They are approximately equal to both hypertension and diabetes mellitus. This is different from other studies [5]. Heart diseases are more comorbid with schizophrenia than other mental illnesses, while hypertension is higher among patients with mental retardation. Schizophrenia is the commonest mental disorder among psychiatric inpatients in Taif mental hospital. The study showed that, hypertension is less in schizophrenia as compared to other studies [15]. Diabetes mellitus prevalence is higher among patients of other psychiatric diagnoses than that in schizophrenia or mental retardation. This may be attributed to the presence of bipolar affective disorders and major depressive disorders among other psychiatric diagnoses group, although it is lower than its prevalence in depression when compared to other studies [12,13,15,16]. The three groups of medical illnesses have same prevalence among the patients labeled with other psychiatric diagnoses.

Limitations

The major limitation of this study is the use of secondary data in which the files are incomplete and inaccurate.

Conclusion

Heart diseases were the highest medical comorbidity among psychiatric inpatients who had medical comorbidity. They are more with schizophrenia which represented the commonest mental illness. Psychiatric inpatients should receive regular thorough medical assessment, particularly for heart diseases, hypertension and diabetes mellitus.
