In 30 seconds
This systematic review examined the relationship between life-course socioeconomic position (SEP) and cardiovascular diseases (CVD) among older adults in low- and middle-income countries (LMICs). It included six studies from middle-income countries, revealing inconsistent associations with CVD risk. Notably, three analyses supported the critical period model, while two supported the accumulation model, highlighting the complexity of these relationships.
Key findings
- Three analyses supported the critical period model linking low SEP to higher CVD risk.
- Two analyses supported the accumulation model, but results were inconsistent.
- No studies evaluated the social mobility model in relation to CVD.
Why it matters
Understanding the impact of socioeconomic factors on cardiovascular health is crucial for developing targeted interventions. This review highlights the need for further research to clarify these relationships, particularly in low-income settings where data is scarce.
What to keep in mind
All included studies were conducted in middle-income countries, limiting the generalizability to low-income countries.
