Determinants of Malnutrition among Adults Psychiatric patients Attending Psychiatric Follow-up Clinics in Public Hospitals in Hawassa, Southern Ethiopia: A Convergent Mixed-Methods Study

In the crowded landscape of public health, where infectious diseases and famine often grab the headlines, a quieter but equally damaging struggle plays out within the minds and bodies of those living with mental illness. Malnutrition is not merely a lack of food; it is a state where the body does not receive the right balance of nutrients to function, repair itself, or maintain its strength. For most people, this condition stems from a simple shortage of resources, but for patients with psychiatric disorders, the causes are layered and complex. Their mental health conditions can alter appetite, distort the desire to eat, or make the simple act of preparing a meal feel impossible. Furthermore, the medications used to treat these conditions can change how the body processes food or suppress hunger. When these biological and psychological hurdles meet the harsh realities of poverty and social isolation, the risk of becoming malnourished skyrockets, often going unnoticed by the very doctors treating the mind.

In the city of Hawassa, in the southern region of Ethiopia, a team of researchers set out to understand this hidden crisis among adults seeking care for mental health conditions. They focused on the public hospitals where these patients regularly return for follow-up appointments, looking beyond their psychiatric diagnoses to see the state of their physical bodies. The researchers knew that while mental illness is well-documented, the nutritional status of these specific patients in this region had never been systematically studied. They wanted to find out exactly how many of these individuals were struggling with malnutrition and, more importantly, what factors were driving this problem. Was it the severity of their mental illness, the side effects of their medication, or something outside the hospital walls, such as the lack of money for food or the absence of family support?

To answer these questions, the team conducted a comprehensive study involving 308 adult patients over a three-month period. They did not rely on a single method of investigation but instead combined two approaches to get a full picture. First, they gathered hard data by measuring the patients' height and weight to calculate their body mass index, a standard way to determine if a person is underweight. They also asked detailed questions about the patients' lives, including what they ate, how often they ate, whether they had access to money for food, and if they used substances like alcohol, tobacco, or khat. They assessed how much support the patients received from family and friends and reviewed their medical charts to see what medications they were taking. To fill in the gaps that numbers alone could not explain, the researchers also held group discussions and one-on-one interviews with patients, their caregivers, and hospital staff. These conversations allowed the participants to share their personal stories about the daily struggles of eating when one is depressed, isolated, or financially broke.

The results revealed a stark reality: nearly one in four of the psychiatric patients studied was malnourished. This is a significant portion of the population, indicating that poor nutrition is a widespread companion to mental illness in this setting. The study identified several clear factors that made a patient much more likely to be malnourished. The most powerful predictor was food insecurity, meaning the household did not have reliable access to enough food. Patients living in households where food was scarce were far more likely to be malnourished than those who could reliably put food on the table. Living in a rural area also increased the risk, likely due to limited access to diverse foods and economic opportunities. Being male was another factor associated with higher rates of malnutrition in this specific group.

Beyond the physical environment, the study found that the social and behavioral aspects of the patients' lives played a critical role. Those who had poor social support—meaning they lacked family or friends to help them shop, cook, or simply encourage them to eat—were significantly more likely to be malnourished. The use of psychoactive substances, such as alcohol, tobacco, and khat, was also a major driver. These substances can suppress appetite and divert the little money a patient might have away from food and toward the drug. Additionally, the frequency of meals mattered greatly; patients who ate two or fewer meals a day were at a much higher risk than those who ate three or more. The qualitative interviews brought these statistics to life, with patients describing how depression made them forget to eat, how they spent their limited money on khat instead of food, and how living alone made the simple task of cooking feel insurmountable.

The researchers also uncovered a gap in the healthcare system itself. Despite the clear link between mental health and nutrition, the hospitals where these patients received care did not routinely check for malnutrition. Doctors and nurses, often overwhelmed by heavy workloads and a shortage of staff, focused primarily on the psychiatric symptoms, leaving the nutritional needs of the patients unaddressed. The interviews with health workers confirmed that nutrition was rarely part of the treatment plan, and there were few dietitians available to guide patients on what to eat. This systemic oversight meant that even when a patient was physically wasting away, the medical team might not notice until it was too late.

The study concludes that malnutrition among adult psychiatric patients in Hawassa is not caused by a single factor but by a web of interconnected challenges. It is driven by the inability to afford food, the isolation that comes with mental illness, the use of substances that replace food, and a healthcare system that has not yet integrated nutritional care into mental health treatment. The findings suggest that to improve the health of these patients, interventions must go beyond prescribing medication. They must include efforts to ensure food security, strengthen social support networks, address substance use, and train medical staff to recognize and treat malnutrition as a core part of psychiatric care. Without addressing these root causes, the cycle of poor nutrition and poor mental health will continue to undermine the recovery of thousands of individuals in the region.
