Latent Profiles of Emotional Distress and Sleep and Their Correlates Among Hospitalized Patients With Hypertension and Diabetes: A Multicenter Cross-Sectional Study
This multicenter cross-sectional study of 529 hospitalized patients with hypertension and diabetes identified three distinct latent profiles of emotional distress and sleep characteristics, revealing that serious clinical status, nutritional risk, and specific coping strategies are significantly associated with membership in the emotional distress–predominant profile.

When a person is hospitalized with chronic conditions like high blood pressure and diabetes, the medical team focuses heavily on the physical numbers: blood pressure readings, blood sugar levels, and heart function. Yet, inside the hospital room, the patient's experience is often shaped by invisible forces that are just as real as a fever or a wound. These include the heavy weight of worry, the sharp edge of fear, and the frustrating inability to sleep. For decades, doctors and nurses have known that these emotional and sleep problems often travel together in people with chronic illness, but they have struggled to see the full picture. Usually, medical assessments treat these issues as separate items on a checklist, adding up scores to get an average. But human experience rarely averages out; it clusters in specific, recognizable patterns. A new study from China seeks to map these patterns, moving beyond simple averages to understand how emotional distress and sleep troubles actually combine in the bodies of hospitalized patients. By looking at the specific ways these symptoms group together, researchers hope to help nurses and doctors see the unique needs of each patient, rather than just seeing a collection of symptoms.
The researchers, working across four hospitals in Hubei Province, gathered a group of 529 adults who were currently admitted to the hospital with confirmed diagnoses of both hypertension and diabetes. These patients were not just a random sample; they represented a wide cross-section of people living with these conditions, ranging from those in stable condition to those in serious or critical states. To understand their inner lives, the team asked them to fill out a series of detailed questionnaires. These tools asked about how often they felt down or anxious over the past two weeks, and how they had slept over the past month. The sleep questions were particularly granular, breaking the night down into seven distinct parts: how long it took to fall asleep, how often they woke up, whether they used sleeping pills, and how tired they felt during the day. The researchers also asked about how the patients coped with their illness, whether they felt supported by family and friends, and their current nutritional status.
Instead of simply averaging these answers to find a "typical" patient, the researchers used a sophisticated statistical method to find hidden groups, or profiles, within the data. They were looking for clusters of people who shared similar patterns of symptoms. The analysis revealed that the patients did not fall into one uniform group, nor did they simply range from "very sick" to "very well." Instead, the data sorted them into three distinct categories. The largest group, making up nearly 62 percent of the patients, was characterized by low levels of emotional distress and few sleep problems. These individuals were relatively stable in both their mood and their rest. A second, substantial group, comprising about 31 percent of the patients, showed a different pattern: they suffered from significant emotional distress, with high levels of depression and anxiety, yet their sleep problems were only moderately elevated. They were the most emotionally troubled, but not necessarily the most sleep-deprived. The third and smallest group, representing just over 7 percent of the patients, presented a unique and specific challenge. These individuals did not report high levels of depression or anxiety. Instead, their primary struggle was with sleep. They relied heavily on sleeping medication, woke up frequently, and suffered from severe daytime dysfunction, feeling unable to function normally during the day despite having relatively calm emotions.
The study then looked at what factors were linked to these different groups. The researchers found that the group struggling most with emotional distress was distinctively different in their physical and psychological circumstances. Patients in this group were more likely to be in a serious or critical clinical state, meaning their physical illness was more severe. They also had higher scores for nutritional risk, suggesting their bodies were under greater strain or they were eating less. Psychologically, this group tended to use coping styles that involved avoiding the problem or resigning themselves to helplessness, rather than confronting the illness directly. Interestingly, the group that was primarily struggling with sleep and daytime dysfunction did not show a clear link to these specific physical or psychological factors in the same way. Their sleep issues appeared to be driven by a different set of circumstances, possibly related to the hospital environment, specific medications, or other factors not fully captured by the study's questions.
This distinction is crucial because it challenges the idea that emotional distress and sleep problems always rise and fall together. In the past, a nurse might have assumed that a patient with severe sleep issues was also deeply depressed, or that a patient with high anxiety was also unable to sleep. This study shows that is not always true. A patient can be emotionally overwhelmed but still manage to sleep, while another can be emotionally calm but completely unable to rest due to medication side effects or environmental disruptions. The findings suggest that a "one-size-fits-all" approach to assessing these patients is insufficient. For the nurses and doctors caring for these patients, the study offers a clearer way to look at the whole person. It suggests that when a patient is admitted, the care team should look for these specific configurations of symptoms. If a patient falls into the emotional distress group, the focus might need to be on psychological support and managing the stress of a serious illness. If a patient falls into the sleep-dysfunction group, the focus might need to shift to reviewing their medication, checking for pain, or adjusting the hospital environment to reduce noise and light. By recognizing these different patterns, medical teams can move beyond treating isolated symptoms and start addressing the specific, complex reality of the patient's experience.
