Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Hypertension (n=323). Intervention: Anhedonic subtype of major depression vs. No major depression (reference) and non-anhedonic subtype of major depression. Primary outcome: Presence of type 2 diabetes (OR 2.62, 95% CI 1.21 to 5.66, p=0.040).

Q: What does this research mean for the field?

The anhedonic subtype of major depression, unlike the non-anhedonic subtype, is significantly associated with an increased likelihood of type 2 diabetes in hypertensive individuals. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key result

Anhedonic depression linked to ~2.6-fold higher odds of type 2 diabetes in hypertensive patients.

OR 2.62
95% CI 1.21 to 5.66
P=0.040

Why the study?

Data in the literature regarding the association between type 2 diabetes and the anhedonic subtype of major depression in hypertensive individuals were limited.

Is the anhedonic subtype of major depression associated with a higher likelihood of having type 2 diabetes in hypertensive individuals?

Key Points

To investigate the association between type 2 diabetes and the anhedonic subtype of major depression in hypertensive individuals.
Analyzed demographic and polysomnographic data from 323 hypertensive individuals (61 with type 2 diabetes and 262 without) recruited from the Erasme Hospital Sleep Laboratory database.
Identified type 2 diabetes via American Diabetes Association criteria and evaluated depression subtypes using the Beck Depression Inventory.
Conducted multivariate logistic regression analyses adjusting for major confounding factors.
The rate of type 2 diabetes was 18.9% (n = 61), while the rates of anhedonic and non-anhedonic major depression were 15.8% (n = 51) and 15.5% (n = 50), respectively.
Compared to hypertensive individuals without diabetes, those with diabetes showed reduced slow-wave sleep (6.0% vs. 7.0%, p = .035) and increased wake after sleep onset (16.0% vs. 12.0%, p = .011).
After adjusting for major confounding factors, multivariate logistic regression demonstrated that unlike the non-anhedonic subtype, only the anhedonic subtype of major depression was significantly associated with a higher likelihood of having type 2 diabetes.

Is the anhedonic subtype of major depression associated with a higher likelihood of having type 2 diabetes in hypertensive individuals?

P

Population

323 adult hypertensive patients (median age 52 years, 36.2% female) referred to the Erasme Hospital Sleep Laboratory between 2017 and 2019, excluding those with non-type 2 diabetes or severe uncontrolled somatic/psychiatric comorbidities.

E

Exposure

Anhedonic subtype of major depression (n=51, 15.8%) and non-anhedonic subtype of major depression (n=50, 15.5%), diagnosed via systematic psychiatric assessment according to DSM-5 criteria.

C

Comparator

Hypertensive individuals without major depression (n=222, 68.7%).

O

Outcome

Odds Ratio: 2.62 (95% CI 1.21–5.66)

Absolute Event Rate: 31.4% vs 17.1%

p-value: p=0.040

Identifies that specifically the anhedonic subtype of major depression—rather than non-anhedonic depression—is independently associated with type 2 diabetes in hypertensive patients, suggesting a need for targeted screening and management in this high-risk group.

Limitations

Retrospective data from a clinical database that cannot be verified directly with the patient in most cases, requiring replication in prospective studies.
Exclusion of other types of diabetes limits generalisability solely to type 2 diabetes.
Focus only on anhedonic and non-anhedonic subtypes of major depression limits generalisation to other subtypes.
Sample restricted to hypertensive individuals who agreed to undergo a sleep laboratory evaluation, limiting generalisability.
Retrospective data analysis that could not be verified directly with patients in most cases
Results only applicable to type 2 diabetes due to exclusion of other diabetes types
Results cannot be generalized to subtypes of major depression other than anhedonic and non-anhedonic subtypes
Selection bias from recruiting only hypertensive individuals referred to and agreeing to a sleep laboratory examination

Implication

Anhedonic depression may identify hypertensive patients at higher diabetes risk; leaves open causality and requires longitudinal validation.

Abstract

Given the limited data in the literature, the aim of this study was to investigate the association between type 2 diabetes and anhedonic subtype of major depression in hypertensive individuals. Demographic and polysomnographic data from 323 hypertensive individuals recruited from the database of the Erasme Hospital Sleep Laboratory were analysed. Only individuals with a diagnosis of type 2 diabetes according to the diagnostic criteria of the American Diabetes Association at admission were included in the "diabetes group". Logistic regression analyses were used to study the association between type 2 diabetes and anhedonic subtype of major depression in hypertensive individuals. The rate of type 2 diabetes was 18.9% in our sample of hypertensive individuals. After adjusting for major confounding factors, multivariate logistic regression analyses demonstrated that unlike the non-anhedonic subtype of major depression, only the anhedonic subtype of major depression was significantly associated with higher likelihood of having type 2 diabetes in hypertensive individuals. In this study, the authors demonstrated that the anhedonic subtype of major depression is significantly associated with type 2 diabetes in hypertensive individuals, which could potentially open up new perspectives for the development of therapeutic strategies complementary to conventional treatments for type 2 diabetes in this subpopulation at high risk of complications related to the co-occurrence of this metabolic disorder.

Willame et al. (2022) conducted a cross-sectional in Hypertension (n=323). Anhedonic subtype of major depression vs. No major depression (reference) and non-anhedonic subtype of major depression was evaluated on Presence of type 2 diabetes (OR 2.62, 95% CI 1.21 to 5.66, p=0.040). The anhedonic subtype of major depression was associated with a higher likelihood of type 2 diabetes in hypertensive patients.
