Unmarried individuals face a significantly higher likelihood of developing depression compared to their married counterparts, a new study published in Nature Human Behavior revealed. The research, led by Cuicui Wang of Harvard University, analyzed data from 106,556 participants across seven countries — the US, UK, Mexico, Ireland, Korea, China, and Indonesia. The findings indicate that marital status plays a crucial role in mental health outcomes."Our analysis revealed that unmarried individuals had a higher risk of depressive symptoms than their married counterparts across all countries," the authors stated.Depression Is The New Global PandemicDepression has become the new health pandemic. It currently affects 5% of adults globally and is projected to rise to over 10% by 2025. According to the study, unmarried individuals are 79% more likely to experience depression than married people. Widowed individuals also face an increased risk of 64%, while divorced or separated people show a staggering 99% higher likelihood of depression compared to happily married couples.Beyond Emotional SupportThe health advantages of marriage extend beyond emotional well-being. Recent data published in Global Epidemiology indicates that marriage reduces mortality rates by a third for women. Additionally, even unhappily married individuals often fare better health-wise than those who are single.Research suggests that marriage or cohabitation correlates with lower blood sugar levels, regardless of spousal support or strain. This may be due to shared economic resources, mutual social support, and the positive influence partners have on each other's mental health, according to Wang and her co-authors.Cultural Differences And Contributing FactorsThe study also highlights regional variations. Single individuals in western countries such as the US, UK, and Ireland were at the highest risk of depression as compared to their eastern counterparts in nations like China, Korea, and Indonesia.Notably, lifestyle factors like alcohol consumption further amplified the risk. Among participants in China, Korea, and Mexico, higher alcohol intake was associated with an increased likelihood of developing depression, especially among singles, widows, and divorcees.Understanding DepressionCentres for Disease Control and Prevention (CDC) defines depression as a common but serious mental health condition that negatively affects how a person feels, thinks, and handles daily activities. Unlike occasional feelings of sadness, depression lasts for at least two weeks and can interfere with work, school, relationships, and overall quality of life. In extreme cases, it can prompt a person to end their life.Key symptoms of depression include:- Persistent sadness or empty mood- Loss of interest or pleasure in activities once enjoyed- Fatigue or decreased energy- Difficulty concentrating, remembering, or making decisions- Changes in appetite and weight (increase or decrease)- Sleep disturbances (insomnia or oversleeping)- Feelings of guilt, worthlessness, or hopelessness- Physical symptoms like aches or digestive problems without a clear cause- Thoughts of death or suicideIf you or someone you know is experiencing these symptoms, seek professional help. It is important to note that depression is treatable, and early intervention can make a significant difference to the person's life.
