Black women with symptoms of depression more often report sleep disturbances, self-criticism, and irritability than stereotypical symptoms such as depressed mood, according to a new study led by researchers at NYU Rory Meyers College of Nursing and Columbia University School of Nursing.
“Based on our findings, it’s possible that health care providers may miss depression symptoms in Black women, resulting in underdiagnosis and undertreatment,” said Nicole Perez, Ph.D., RN, a psychiatric-mental health nurse practitioner and postdoctoral associate at NYU Rory Meyers College of Nursing and the lead author of the study published in Nursing Research.
Depression is diagnosed based on symptoms that patients report during an evaluation by a health provider. Common symptoms include low mood, loss of interest in activities, changes in appetite or sleep, and feelings of hopelessness or worthlessness.
But symptoms of depression can vary from one person to the next—and there are more than 1,500 possible combinations of symptoms that meet criteria for a depressive disorder, meaning that patients can share the same diagnosis and have no symptoms in common. As a result, depression often gets overlooked and undertreated.
Moreover, research exploring variations in depression symptoms has been predominantly conducted in white people, increasing the chances that depression will be missed among racial and ethnic minority populations.
The Nursing Research study aimed to address this research gap by exploring variations in depression symptoms among Black women, a population that is understudied despite being at increased risk for depression.
The researchers analyzed data from 227 Black women who were screened for depression as part of the Intergenerational Impact of Psychological and Genetic Factors on Blood Pressure (InterGEN) study, a study of Black mothers and children that seeks to understand the genetic, psychological, and environmental factors that contribute to high blood pressure.
Black women in the study with greater depressive symptoms were more likely to report somatic symptoms (e.g. fatigue, insomnia, decreased libido) and self-critical symptoms (e.g. self-hate, self-blame) than stereotypical depression symptoms such as feelings of hopelessness or depressed mood. They also reported experiencing anhedonia (an inability to experience pleasure) and irritability.
While the researchers caution that the results cannot be generalized to all Black women, given that the study participants were younger and had relatively low levels of depression, their findings demonstrate the heterogeneity in depression symptoms and need for screening tools that account for this variation. Notably, symptoms experienced by Black women may not be adequately assessed in clinical practice using standard screening tools, especially those that focus on feeling depressed without addressing somatic and self-critical symptoms.
