Association Between Serum Lipid Levels and Severe Headache or Migraine in Representative American Population: A Cross-sectional Study.

BACKGROUND

The relationship between serum lipids and migraine remains controversial.

OBJECTIVE

This study aimed to analyze the association between serum lipids and severe headache or migraine in the general population.

METHODS

Data were collected from a nationally representative sample of participants in the National Health and Nutrition Examination Survey from 1999 to 2004. Interviewers recorded self-reported severe headaches or migraines and whether pain lasted for more than 24 h in three months. A weighted general linear model was used to estimate the association between serum lipids and severe headache or migraine. Regression analyses were performed after adjusting for age, sex, race, energy intake, sodium intake, etc. Subgroup analyses were performed using the same regression model.

RESULTS

We included 5,937 individuals in the study, with a weighted mean age of 45.8 years. Males accounted for 47.6% of the participants. After adjusting for covariates, a non-significant association was found between migraine and total cholesterol (odds ratio=0.96, 95% confidence interval= 0.85, 1.05; P=0.32), low-density lipoprotein cholesterol (odds ratio=0.96; 95% confidence interval= 0.75, 1.17, P=0.55), and high-density lipoprotein cholesterol (odds ratio=0.99; 95% confidence interval=0.49, 1.59, P=0.58) in the continuous form. In subgroup analyses, no significant association was found between total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and self-reported severe headache or migraine.

CONCLUSION

Total cholesterol, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol were not significantly associated with severe headache or migraine in the general American population after adjusting for covariates. The supporting information for measuring common serum lipids in general headaches and migraines is insufficient.
