Quick Answer
Carnosine Sleep Quality Meta-Analysis has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: Individuals with T2DM have a higher risk of mental health disorders (Arias et al. ; Deshpande et al. ; Ducat et al. ), with the prevalence of depression reported to be two‐fold higher in those with T2DM compared with the general population (Roy and Lloyd ).
Key Takeaways
- 01Individuals with T2DM have a higher risk of mental health disorders (Arias et al. ; Deshpande et al. ; Ducat et al. ), with the prevalence of depression reported to be two‐fold higher in those with T2DM compared with the general population (Roy and Lloyd ). [Kabthymer Robel Hussen (2026)]
- 02Similarly, the prevalence of depression is moderately increased in individuals with prediabetes compared with their normo‐glycaemic counterparts (Chen et al. ). [Kabthymer Robel Hussen (2026)]
- 03This increased risk may be partly due to diabetes‐related distress, which affects a large proportion of this population and can contribute to depressive symptoms (Perrin et al. ). [Kabthymer Robel Hussen (2026)]
- 042021 2023 2019 2023 2022 Globally, approximately half a billion individuals live with diabetes, with type 2 diabetes mellitus (T2DM) accounting for 90% of the disease burden (IDF ). [Kabthymer Robel Hussen (2026)]

- The other recent systematic review and meta-analysis (Song et al.) showed that older patients living with PU experience two times higher risk of mortality than those who do not have such wounds. [Świątkiewicz Maciej (2025); evidence level 4]
Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording.
