Objective:To describe the prevalence of food allergy among children aged 0-5 years in China and to explore related influencing factors.Methods:Multistage stratified random sampling method was used to collect data from 275 surveillance sites of the China National Nutrition and Health Survey of Chinese children and lactating mothers programs in 31 provinces (autonomous regions and municipalities) of China in 2016-2017. A total of 70 107 participants aged 0-5 years were included in this study. The study collected information of participants' demographic characteristics and food allergies by face-to-face questionnaire. The prevalence of food allergy was analyzed, using the complex data weighting method. The logistic regression models were used to analyze the influencing factors related to food allergy.Results:The overall prevalence of self-reported food allergy among children aged 0-5 years was 4.81%. Prevalence rates in infants aged 0-5 months, and 6-23 months and preschool children aged 2-5 years were 0.81%, 4.68% and 5.26%, respectively. The results of logistic analysis showed that there was a significantly positive correlation between factors including children from 6 months to 5 years old, urban area, southwest area, first-born, mothers with college education or above, and the prevalence of food allergy in children. Shrimp, poultry eggs, crab shellfish, fruit, milk and fish appeared the common allergic foods in children aged 0-5 years, with prevalence rates of self-reported food allergy as 1.55%, 1.25%, 0.99%, 0.97%, 0.87% and 0.86%, respectively. The proportion of single food allergy in children with allergies was 69.85%.Conclusions:Among children aged 0-5 years, the prevalence of self-reported food allergy increases with age, in China. Foods that is prone to allergies include fish, shrimp, crab, shellfish, poultry eggs, milk and fruits, etc. Most allergies were only caused by single food in children, under observation.

Objective:To investigate the effect of MCC950 (a NLRP3 inflammasome inhibitor) on cognitive impairment in mice with radiation-induced inflammatory brain injury.Methods:Mice were divided into normal (NS) group, whole body irradiation (IR) group and MCC950 intervention post irradiation (IR+ MCC950) group according to the random number table method, with 15 mice in each group. The mice in IR group and IR+ MCC950 group were irradiated with a single dose of 4.0 Gy. The radiation source was 137Cs and the dose rate was 1.118 Gy/min. The mice in NS group were not irradiated. Mice in IR+ MCC950 group were injected intraperitoneally with MCC950 once a day (10 mg/kg each time) from 3 weeks after irradiation. Behavioral tests such as new and old things recognition experiment and social cognition experiment were used to detect the cognitive function of mice. Immunohistochemistry was used to detect the expression of NeuN protein in CA3 area of mouse hippocampus. PCR and Western blot were used to detect the expression of NLRP3 inflammatory body related protein. Results:Compared with NS group, the short-term and long-term recognition index of new and old things in the IR group decreased significantly ( t=4.321, 5.473, P<0.01), and the social cognitive recognition index of the IR group also decreased significantly ( t=2.097, P<0.05). MCC950 treatment reversed the above changes (short-term and long-term new and old thing recognition test: t=5.860, 4.598, P<0.05; new and old position recognition test: t=3.040, P<0.05; social cognition test: t=4.021, P<0.01). The expression of NLRP3, Caspase-1, IL-1 β and IL-18 in mice hippocampus of the IR group was significantly higher than that of the control group ( t=2.699, 8.515, 3.340, 3.950, P<0.05). Compared with NS mice, radiation significantly increased the expressions of Bax, Caspase-3 and PARP1 in hippocampus ( t=3.887, 2.742, 3.287, P<0.05), while MCC950 significantly decreased the expressions of Bax, Caspase-3 and PARP1( t=2.852, 4.090, 9.614, P<0.05). Conclusions:NLRP3 inflammasome inhibitor MCC950 could alleviate radiation-induced cognitive impairment, which may be due to the inhibition of hippocampal inflammatory and neuronal death.

Objective:To explore the association between parental socioeconomic status (SES) and preschoolers’ consumption of sugar-sweetened beverages (SSB).Methods:In June 2018, all preschoolers from 15 kindergartens were selected from the jurisdiction of Education Commission in Dongcheng District of Beijing by using an equal-proportion stratified cluster sampling method in the study. A self-designed questionnaire was used to investigate the parents of preschoolers to obtain the basic information of preschoolers and parents, the consumption situation of preschoolers’ sugar-sweetened beverages and the perception of parents to SSB. A tatol of 3 217 preschoolers were finally included in the analysis. A generalized structural equation model was used to analyze the relationship between preschoolers' consumption of sugar-sweetened beverages and their parents' socioeconomic status and the mediating effect of their cognition of sugar-sweetened beverages. The size of mediating effect was estimated by using deviation correction non-parameter percentile Bootstrap method.Results:The age of 3 217 preschoolers was (4.23±0.67) years, of which 52.6% ( n=1 692) were boys, and 77.62% ( n=2 497) were SSB consumers. Among the parents of 3 217 preschoolers, fathers and mothers accounted for 24.90% ( n=801) and 75.10% ( n=2 416), and the M ( P25, P75) scores of SES were 66.7 (62.5, 69.5) and 69.5 (64.6, 71.4), respectively. The proportion of parents who took the initiative to learn about their children's consumption of SSB, lacked confidence in restricting preschooler's consumption of SSB and read nutrition labels before purchasing food was 74.08% ( n=2 383), 82.90% ( n=2 667) and 36.24% ( n=1 166), respectively. The generalized structural equation model showed that after adjusting for preschoolers’ gender, age, body mass index (BMI) of preschoolers and their parents, preschoolers’ consumption of SSB was negatively associated with their parents’ SES score [path coefficient (95% CI):-4.69×10 -2 (-6.56×10 -2,-2.69×10 -2) ]. The mediating effect of parents’ perception of SSB consumption could explain 48.71% of the total effect [path coefficient (95% CI):-2.28×10 -2 (-3.54×10 -2, -1.10×10 -2)]. Conclusion:The consumption of SSB in preschoolers is negatively associated with their parent’s SES, and this relationship is partially mediated by parent’s perception of SSB consumption.

Background::Breast cancer (BC) risk-stratification tools for Asian women that are highly accurate and can provide improved interpretation ability are lacking. We aimed to develop risk-stratification models to predict long- and short-term BC risk among Chinese women and to simultaneously rank potential non-experimental risk factors.Methods::The Breast Cancer Cohort Study in Chinese Women, a large ongoing prospective dynamic cohort study, includes 122,058 women aged 25-70 years old from the eastern part of China. We developed multiple machine-learning risk prediction models using parametric models (penalized logistic regression, bootstrap, and ensemble learning), which were the short-term ensemble penalized logistic regression (EPLR) risk prediction model and the ensemble penalized long-term (EPLT) risk prediction model to estimate BC risk. The models were assessed based on calibration and discrimination, and following this assessment, they were externally validated in new study participants from 2017 to 2020.Results::The AUC values of the short-term EPLR risk prediction model were 0.800 for the internal validation and 0.751 for the external validation set. For the long-term EPLT risk prediction model, the area under the receiver operating characteristic curve was 0.692 and 0.760 in internal and external validations, respectively. The net reclassification improvement index of the EPLT relative to the Gail and the Han Chinese Breast Cancer Prediction Model (HCBCP) models for external validation was 0.193 and 0.233, respectively, indicating that the EPLT model has higher classification accuracy.Conclusions::We developed the EPLR and EPLT models to screen populations with a high risk of developing BC. These can serve as useful tools to aid in risk-stratified screening and BC prevention.

Objective:To investigate sleep quality in pregnant women during their first and second trimester and to identify risk factors.Methods:Data was from the Chinese Pregnant Women Cohort Study. A total of 3 618 pregnant women were included, with the exclusion 346 women who had missing information. Sociodemographic, health-related behavior, depression and sleep quality information were collected and analyzed. Logistic regression analysis were used to explore the influencing factors of sleep quality in pregnant women.Results:Among the 3 618 pregnant woman 28.2% had poor sleep quality in their first trimester and 28.7% in the second trimester. 15.2% pregnant women had progressively worse sleep and 13.0% had persistently poor sleep had pregnant women were generally suffered from poor sleep quality, difficulty falling asleep, sleep disorders and daily fatigue. Regular diet ( OR=0.75, 95% CI: 0.62-0.92) and work ( OR=0.84,95% CI: 0.71-0.99) in the first trimester were protective factors of sleep quality in pregnant women. Age ≥30 year old ( OR=1.19, 95% CI: 1.03-1.37), passive smoking ( OR=1.18, 95% CI: 1.02-1.36) and depression ( OR=2.25, 95% CI: 1.95-2.61) in the first trimester were risk factors. Conclusions:The rate of poor sleep quality are high among Chinese pregnant woman during their first and second trimester. The risk factors of sleep quality are multiple. Regular diet and work, reduction of tobacco exposure, alleviation of depression symptom may help improve sleep quality among pregnant women.
