Animal experiments have found that oil tea reduces body weight and improves blood lipid levels. 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.
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).
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 ( < 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.
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.
动物实验发现油茶可减轻体重并改善血脂水平。然而，油茶对人体健康的影响尚未得到证实。本研究旨在探讨食用油茶与肥胖及血脂异常之间的关系。
在中国广西进行的一项横断面人群研究中，采用半定量问卷调查30岁及以上成年人的油茶饮用量和食物消费频率。测量人体测量学变量和血清生化指标。根据油茶饮用状态和消费四分位数，将2001名成年人分为五组（不饮用油茶组、Q1-Q4组）。
在总体参与者（Q3组，OR = 0.545，95%CI = 0.336-0.884；Q4组，OR = 0.520，95%CI = 0.311-0.871）和女性（Q2组，OR = 0.502，95%CI = 0.274-0.920；Q3组，OR = 0.397，95%CI = 0.213-0.740；Q4组，OR = 0.421，95%CI = 0.228-0.780）中，随着油茶消费量的增加，腹部肥胖风险有显著降低趋势（趋势P<0.05）。油茶消费Q1、Q2、Q3和Q4组显著降低了高密度脂蛋白胆固醇异常风险（P<0.05）。油茶消费Q2组显著增加了女性低密度脂蛋白胆固醇异常风险（OR = 2.600，95%CI = 1.033-6.546）。油茶消费Q1组（OR = 0.081，95%CI =0.008-0.864）和Q3组（OR = 0.057，95%CI = 0.004-0.913）显著降低了女性高密度脂蛋白胆固醇异常风险。
食用油茶可能与腹部肥胖风险较低有关。高剂量食用油茶可能与高密度脂蛋白胆固醇异常风险较低有关。需要进行大样本前瞻性研究以进一步探究这种关联。
