Association between mustard oil consumption and thrombocytopenia: a case-control study in Bangladesh
Abstract
Background and objectives: Mustard oil, a common ingredient in South Asian cuisine, has been associated with both culinary appeal and potential health benefits. While studies suggest its role in reducing the risk of ischemic heart disease, concerns arise due to the presence of erucic acid, which has been linked to adverse cardiovascular effects and thrombocytopenia. This case-control study aimed to investigate the association between mustard oil consumption and thrombocytopenia in the Bangladeshi population.
Materials and methods: Consecutive patients diagnosed with thrombocytopenia (platelet count < 150000/µL) were enrolled as cases, while controls were selected as the next consecutive patients with normal platelet counts, regardless of demographic characteristics or disease status. Data on demography, clinical variables and mustard oil consumption were collected from medical records and face-to-face interviews.
Results: Seventy-six participants were included in the study of which 38 belonged to case and 38 to control groups. The mean age of the individuals in control and case groups was 57.5 and 58.2 years respectively (p = 0.808). Notably, 83.3% of cases reported using mustard oil compared to 28.3% of controls (p<0.001). Cases exhibited significantly (p < 0.001) lower platelet counts (114,789 ± 24,453 /µL) compared to controls (278,211 ± 84,595 /µL). Male gender and the use of mustard oil in cooking were identified as predictors of thrombocytopenia. No bleeding symptoms…
How strong is the evidence?
Evidence Hub reads this as a case-control, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
