Association between Berlin Questionnaire Index and lipid profile.

Objective: This study aimed to evaluate the association between the Berlin questionnaire index and the lipid profile, according to gender.

Method: This is a cross-sectional study. The group investigated was composed of the Bahiana School of Medicine and Public Health (EBMSP) employees by a sequential non-probabilistic sampling. Study design: The data were obtained by applying a validated questionnaire and collecting laboratory blood samples at the Outpatient Clinics of EBMSP.

Results: The total sample consisted of 94 employees, 21 of whom were excluded because they had not been submitted to blood collection. The sample profile evaluation had a total of 73 employees and obtained the following results in the study: the female was the most prevalent with (54.8%); the age ranged from 18 to 65 years, with a mean 38 ± 10.6 years; in men with positive Berlin (with respiratory sleep disorder), higher values of total cholesterol and LDL-c, and lower HDL-c were observed when compared to men without respiratory sleep disorder, as follows: total cholesterol (202 ± 19 vs. 180±40; p=0.040); LDL-c (137± 17 vs. 113 ± 34; p=0.048); lower HDL-c (37 ± 6 vs. 42,5 ±8; p=0.047). While in women, no significant change was observed among those with positive Berlin when compared with those with negative Berlin.

Conclusion: The findings of this study showed that men with positive Berlin (with a respiratory sleep disorder) had higher values of total cholesterol, LDL-c, and lower HDL-c when compared to men without a respiratory sleep disorder.
