A 34-year-old woman from rural Maharashtra presents to the primary health centre with complaints of persistent sadness, loss of interest in household activities, and sleep disturbance for the past 8 months. She reports feeling worthless and has recurrent thoughts of death, though denies any active plan or intent. Her husband attributes her symptoms to 'weakness' and believes she should 'just work harder'. On examination, she appears withdrawn, with psychomotor retardation. She has no significant past medical history and denies substance use. What is the most appropriate public health classification of her current mental health status based on epidemiological burden assessment?

Explanation

## Clinical Assessment This patient presents with a **major depressive episode** meeting DSM-5 criteria: - Persistent depressed mood (8 months) - Anhedonia (loss of interest) - Sleep disturbance - Worthlessness - Suicidal ideation (passive) - Functional impairment ### Epidemiological Classification **Key Point:** The Global Burden of Disease (GBD) framework classifies depression severity by functional disability, not just symptom count. This patient has: - Duration >2 weeks (meets chronicity threshold) - Multiple neurovegetative symptoms - Social/occupational dysfunction (household activities impaired) - Passive suicidality (elevated risk) **High-Yield:** In India, depression accounts for ~2.5% of DALYs (Disability-Adjusted Life Years). Moderate depression with functional impairment carries a disability weight of 0.406–0.510 in GBD 2019 estimates. ### Why This Is Moderate, Not Mild or Severe | Severity | Symptom Count | Disability | Suicidality | Hospitalization Need | |----------|---------------|-----------|-------------|---------------------| | **Mild** | 5–6 symptoms | Minimal | Absent | No | | **Moderate** | 6–7 symptoms | Significant | Passive ideation | Outpatient | | **Severe** | 8+ symptoms | Severe | Active plan/intent | Yes | This patient has **6–7 symptoms with clear functional impairment** and passive suicidal ideation but no active plan—hallmark of **moderate depression**. **Clinical Pearl:** The rural context and husband's dismissal of symptoms highlight the **social determinants** of mental health in India—stigma, limited health literacy, and gender-based barriers to care are major epidemiological drivers of untreated depression in women. **Warning:** Do not confuse "moderate" with "not serious." Moderate depression with suicidal ideation requires active treatment (psychotherapy ± antidepressants) and safety planning, even in an outpatient setting. [cite:Park 26e Ch 16]
