Objective To study the prevalence of food intolerance and to explore its related factors among adult health check-up receivers.Methods A total of 863 adults who took physical examinations in our hospital from April to October 2011 were enrolled in this investigation.Height,body weight and blood pressure were measured,and serum IgG level was measured by enzyme-linked immunosorbent assay (ELISA).Results The total positive rate of food intolerance was 73％,and the leading intolerance items were crab (40.1％ ),egg (29.8％ ),cod fish ( 21.6％ ),milk ( 20.0％ ) and soybean ( 14.4％ ).Females showed significantly higher prevalence of food intolerance than males.Various positive rate of milk or soybean intolerance was found in different age groups.No correlations of serum specific IgG with body mass index and systolic or diastolic blood pressure were observed.In logistic regression analysis,the odds ratio of food intolerance of women was 1.67 ( 95 ％ confidence interval 1.190 to 2.607 ).ConclusionsThe prevalence rate of food intolerance was high.The risk for food intolerance was significantly increased in women.Specific IgG antibody detection may help to early prevent and diagnose food intolerance-related diseases.

OBJECTIVETo investigate the characteristics of brachial-ankle pulse wave velocity (baPWV)in populations having health check-up and to explore its relationship with risk factors of cardiovascular diseases.

METHODS13 841 people who had health check-up were included and their baPWV were tested by automatic arteriosclerosis measurement system. All people were inquired about their diseases history, while height, weight, body mass index(BMI), blood pressure, fasting blood-glucose as well as serum lipid were also measured.

RESULTSWith increasing of age, baPWV were increased both in males and females. The baPWV of male aged less than 60 years was significantly higher than that of female less than 60. Multi-variable regressive analysis showed the age, systolic pressure,BMI, fasting blood-glucose, uric acid and triglyceride were the risk factors of baPWV.

CONCLUSIONBaPWV values of health check-up population in Chengdu area demonstrated different characteristics in different age and gender group. Attention should be paid on baPWV measurement among elder people, especially the elder women, in order to prevent cardiovascular events happening in high risk population.

OBJECTIVETo explore the effect of blood lipid and lipoprotein ratios on the change of brachial-ankle pulse wave velocity (baPWV) among prehypertensive subjects.

METHODS11 611 subjects with normal blood pressure (BP) were divided into two groups, which was one with optimal blood pressure (BP<120/80 mmHg) and the other with prehypertension (BP:120-139/80-89 mmHg). Height, weight, baPWV, fasting blood-glucose, TC, TG, LDL-C and HDL-C were detected.

RESULTSThe abnormal rate of baPWV in prehypertension group was obviously higher than that in the optimal blood pressure group. For optimal blood pressure group, the abnormality of TG, TC, LDL-C, TC/HDL-C as well as LDL-C/HDL-C, caused the increase of baPWV significantly (P < 0.001). For prehypertensive group, the abnormality of TC and LDL-C caused the significant increase of baPWV (P < 0.001). Results from logistic regression analysis showed that except for age, BMI and fasting blood-glucose, TC/HDL-C increasing was the independent risk factor in optimal blood pressure group, while TG increasing was for the prehypertension group.

CONCLUSIONWith different normal BP level, both abnormality of blood lipid and lipoprotein ratio were the independent risk factors for baPWV increasing.
