Physical comorbidity among patients attending mental health services at Windhoek Central Hospital, Namibia.

Introduction: physical health problems are common among people with mental illness. Understanding common co-occurring mental and physical conditions can aid health providers to effectively screen individuals and also integrate care for both conditions. The study aimed to determine the prevalence and types of comorbidity among patients attending the outpatient section of the Mental Health Care Centre, Windhoek Central Hospital. Methods: a cross-sectional survey of 385 patients attending the Mental Health Care Centre of Windhoek Central Hospital was carried out using structured questionnaire. Results: the study found that 33.8% of participants had comorbid physical and mental conditions. The most common co-occurring physical conditions were from the cardiovascular system (40.8%), infections (30.8%), and neurological conditions (13.0%). Female patients were more likely to have comorbidity compared to their male counterparts (OR=2.8; CI = 1.5-5.0; p=0.001), and the risk of comorbidity increased with age (OR=1.1; CI = 1.0-1.1; p<0.001). Conclusion: the study emphasizes the inseparability of mental and physical health, and the bidirectional association between mental and physical conditions. The high prevalence of somatic disorder points to the need of integration of physical and mental health services. Mental health and somatic services must be adjusted to the fact that most of the people who come to seek help are likely to suffer from more than one illness.
