Type 2 diabetes incidence and socio-economic position: a systematic review and meta-analysis

Key Points

• To evaluate the association between socioeconomic position and the incidence of type 2 diabetes across high-, middle-, and low-income countries.
• Conducted a systematic review and meta-analysis investigating the relationship between socioeconomic position (SEP) and type 2 diabetes risk.
• Assessed and compared effect estimates across global income classifications, including high-, middle-, and low-income settings.
• Lower socioeconomic position was significantly associated with an increased risk of type 2 diabetes globally and within high-, middle-, and low-income countries.
• Risk associations showed strong consistency across high-income countries, whereas data from low- and middle-income countries demonstrated substantial need for further research.
