Objective
To explore the combined effect of abdominal obesity and depressive symptoms on the risk to type 2 diabetes, while also assessing the potential influence of various glycemic states and gender on this combined relationship.

Methods
Data is acquired from the China Health and Retirement Longitudinal Study, and 5949 participants were included for analysis. Participants were divided into four groups: neither have abdominal obesity nor depressive symptoms (AO−/DS−), only have depressive symptoms (AO−/DS+), only have abdominal obesity (AO+/DS−), and have both abdominal obesity and depressive symptoms (AO+/DS+). Stratified analyses differentiating the glycemic statuses and sex of the participants were also carried out.

Results
After adjusting for the confounders, the AO−/DS+, AO+/DS− and AO+/DS+ phenotypes were all discovered to be risk factors for type 2 diabetes (OR = 1.38, 95%CI: 1.06–1.79; OR = 2.07, 95%CI: 1.63–2.63; OR = 2.38, 95%CI: 1.83–3.11, respectively) compared with the AO−/DS− phenotype in the overall population. In further stratified analyses, we arrived at the same conclusion for normoglycemic individuals, especially in females. For prediabetes and males, the AO+/DS− and AO+/DS+ phenotypes are risk factors for type 2 diabetes compared with the AO−/DS− phenotype, but not with AO−/DS+.

Conclusion
Regardless of glycemic status and sex, the coexistence of abdominal obesity and depressive symptoms were associated with an increased risk of type 2 diabetes. Depressive symptoms were independent risk factors for type 2 diabetes only in normoglycemic individuals and females.
