Correlation of food intolerance with hyperlipidemia: a cross-sectional survey in healthcare population

Abstract

To explore the correlation of food intolerance and hyperlipidemia. A cross-sectional survey was conducted from August 2008 to June 2009. It recruited a total of 11 434 adults from Health Sciences Center at our hospital. Non-conditional Logistic regression model was utilized for determining odd ratio (OR) and 95% confidencer interval (CI). And statistic analysis was performed with SPSS 13.0. Among them 6 897 participants were food intolerance positive and 4 537 food intolerance negative. The prevalence of food intolerance was 60.32%. Age, gender, smoking, body mass index, total cholesterol, triglycerides and high density lipoprotein (HDL) cholesterol were significantly different between positive and negative ones (all P < 0.05). Multiple regression analysis showed that food intolerance was significantly correlated with age, gender, body mass index, but negatively with hyperlipidemia. Compared with age group ≤ 40 years, the OR (95%CI) of age groups 41-50, 51-60 and >60 years were 1.125(1.021-1.238), 1.350(1.207-1.510) and 1.564(1.279-1.912) respectively. Compared with males, the OR (95%CI) of females was 1.528(1.382-1.689). Compared with normal weighters, the OR (95%CI) of low weighters was 1.720 (1.147-2.580). Compared with normal blood lipids, the OR (95%CI) of hyperlipidemia was 0.879 (0.810-0.955). Food intolerance may be negatively correlated with hyperlipidemia in healthcare population.
