However, the effect of oil tea on human health has not been confirmed yet. This study aims to explore the relationship between oil tea consumption and obesity and dyslipidemia.Methods: In a cross-sectional population study in Guangxi, China, a semi-quantitative questionnaire was used to investigate the oil tea consumed and food consumption frequency in adults aged 30 years and over. Anthropometric variables and serum biochemical indicators were measured. A total of 2001 adults were divided into five groups based on their non-consumption status and quartile of consumption (groups non-drink oil tea, Q1–Q4).Results: The risk of abdominal obesity tended to decrease significantly with increasing consumption of oil tea (P for trend< 0.05) in the overall participants (Q3 group, OR = 0.545, 95% CI = 0.336– 0.884; Q4 group, OR = 0.520, 95% CI = 0.311– 0.871) and in women (Q2 group, OR = 0.502, 95% CI = 0.274– 0.920; Q3 group, OR = 0.397, 95% CI = 0.213– 0.740; Q4 group, OR = 0.421, 95% CI = 0.228– 0.780). Oil tea consumption Q1, Q2, Q3 and Q4 group significantly reduced the risk of abnormal HDL-cholesterol (P < 0.05). Oil tea consumption Q2 group significantly increased the risk of abnormal LDL-cholesterol (OR = 2.600, 95% CI = 1.033– 6.546) in women. Oil tea consumption Q1 (OR = 0.081, 95% CI =0.008– 0.864) and Q3 (OR = 0.057, 95% CI = 0.004– 0.913) groups significantly reduced the risk of abnormal HDL-cholesterol in women.Conclusion: Oil tea consumption may be associated with a low risk of abdominal obesity. High-dose oil tea consumption may be associated with a low risk of abnormal HDL-cholesterol. Prospective studies with large sample sizes would be required to further investigate this association.Keywords: abdominal obesity, blood lipid, HDL-C
