Key result

Highest quartile remnant cholesterol linked to ~49% greater odds of depression versus the lowest.

  • OR 1.49
  • 95% CI 1.02-2.17
  • P=0.04
  • n=8,263

Why the study?

Remnant cholesterol is linked to various diseases, but its relationship with depression had not been studied.

Is higher remnant cholesterol concentration associated with increased odds of depression in US adults?

Population

8,263 adults from NHANES 2005-2016

Comparison

Remnant cholesterol concentration levels

Design

Cross-sectional analysis

Implication

Associated with higher depression odds in US adults; leaves open causality and clinical relevance pending prospective studies.

Study Design

Type

Cross-Sectional (n=8,263)

Structured PICO

Is higher remnant cholesterol concentration associated with increased odds of depression in US adults?

P
Population
8,263 US adults from the National Health and Nutrition Examination Survey (NHANES) 2005-2016, weighted mean age 45.65 years.
I
Intervention
Higher remnant cholesterol concentration (calculated as total cholesterol minus HDL-C minus LDL-C)
C
Comparator
Lower remnant cholesterol concentration
O
Outcome
Depression assessed using a Patient Health Questionnaire (PHQ-9)patient reported

Main Result

Effect estimate: OR 1.49 (95% CI 1.02-2.17)

p-value: p=0.04

Higher remnant cholesterol concentrations are significantly associated with an increased likelihood of depression among US adults.

Limitations

  • Cross-sectional study design cannot derive causality
  • Cholesterol data used was fasting data, while non-fasting data was not studied
  • Remnant cholesterol was calculated indirectly rather than measured directly
  • Potential unmeasured confounding factors

Cite This Study

Wang et al. (2023) conducted a cross-sectional in Depression (n=8,263). Highest quartile of remnant cholesterol vs. Lowest quartile of remnant cholesterol was evaluated on Depression (PHQ-9 score ≥ 10) (OR 1.49, 95% CI 1.02-2.17, p=0.04). Remnant cholesterol concentration in the highest quartile was significantly associated with higher odds of depression compared to the lowest quartile (OR 1.49).
