To explore the positive rate of crab intolerance and its related factors in a healthy physical examination population in Beijing, China.
A cross-sectional survey was carried out from August 1, 2008 to July 30, 2009. It recruited a total of 12 765 adults with crab intorlerance at Health Sciences Center, Chinese PLA General Hospital. The epidemiological data were entered into computer by two persons and organized by Epidata3.0. Non-conditional Logistic regression model was used to calculate the values of odd ratio (OR) and 95%CI. Statistic analysis was performed by SPSS 13.0.
The incidence rate of crab intolerance was 24.5% (3128/12 765) and increased with age. Grades of crab intolerance were associated with age and gender and there was a linear correlation tendency (P < 0.05). Incidence rate of crab intolerance in females (27.5%, 1077/3912) was higher than that of males (23.2%, 2051/8853). Multiple regression analysis showed that crab intolerance was correlated with age, gender, body mass index and helicobacter infections(all P < 0.05). In comparison with age group < 40 years old, the values of OR (95%CI) of age groups 41 - 50, 51 - 60 and > 60 years old were 1.224 (1.095 - 1.368), 1.616 (1.431 - 1.827) and 2.177 (1.799 - 2.634) respectively. In comparison with males, the OR (95%CI) of females was 1.286 (1.174 - 1.408). The OR (95%CI) of Helicobacter pylori infections was 1.303(1.201 - 1.413). In comparison with normal weighters, the OR (95%CI) of obese subjects was 1.154 (1.026 - 1.298).
Crab intolerance may be correlated with age, gender, Helicobacter pylori infections and body mass index. Health education should be targeted at its characteristics.

To explore the prevalence of intolerance to eggs and its relationship with body mass index in Beijing, China.
A cross sectional survey which included 12 766 adults from health sciences center of general hospital of the Chinese People's Liberation Army from August, 2008 to July, 2009 was carried out. Data was entered computer and organized by EpiData 3.0 software for epidemiological analysis. Nonconditional logistic regression model was used for odd ratio (OR) and 95%CI calculation, and statistics analysis was carried out by SPSS 13.0 software.
Positive rate of intolerance to eggs in the cohort was 28.5%. Grades of intolerance to eggs were associated with sex (P < 0.05). Positive rate of intolerance to eggs in females (36.5%) was higher than those in males (24.9%). Data from multiple regression analysis showed that intolerance to eggs was associated with sex and body mass index. Compared with males, the OR (95%CI) of female was 1.732 (1.590 - 1.887). Compared with normal weights, the OR (95%CI) of low weights was 1.443 (1.018 - 2.045).
Sex and body mass index mignt be associated with intolerance to eggs.

To study the prevalence of food intolerance among attendants in a general hospital and to learn its related determinants in Beijing, China.
An cross sectional survey, from August 1st, 2008 to June 30th, 2009, was carried out, including 12 766 adults from Health Sciences Center, Chinese PLA General Hospital. Data for epidemiological analysis were entered (double entry) into computer and organized by EpiData 3.0. Non-conditional logistic regression model was used for odd ratio (OR) and 95%CI calculation, with statistic analysis through SPSS 13.0.
The three leading intolerance food items were egg, crab and milk, and the prevalence rates were 28.5%, 24.5% and 24.5% respectively. Prevalence of food intolerance increased along with aging. Levels and the kinds of food intolerance were associated with age, sex and appeared a linear correlation tendency (P < 0.05). Prevalence of food intolerance in females (67.3%) was higher than that in males (56.2%). Data from multiple regression analysis showed that, comparing with age group under 40 and 40 years, the OR (95%CI) of age group 41 - 50, 51 - 60, and above 60 were 1.125 (1.027 - 1.233), 1.307 (1.176 - 1.452) and 1.536 (1.275 - 1.849) respectively. Compared to males, the OR (95%CI) of females was 1.602 (1.475 - 1.741). When compared with normal weights, the OR (95%CI) of people with low weight was 1.772 (1.207 - 2.602).
Food intolerance was associated with age, sex and body mass index. Health education should be carried out according to the related characteristics of age and sex. Suggesting that reducing the risk of food intolerance, keeping the suitable weight was necessary.
