Objective:To develop a three-dimensional body image stimuli suitable for middle-aged people in China, and verify the validity and reliability of the body image stimuli.Method:According to China and World Health Organization body mass index classification standards of adults, a set of three-dimensional body image stimuli of Chinese middle-aged males and females with different body size was developed by using 3D Studio Max and Adobe Photoshop CC based on the literature and expert consultation method. Forty-two 45- and 59-year-old middle-aged people in Zhengzhou City, Henan Province were recruited to verify the three-dimensional body image stimuli. Through questionnaire survey and physical examination, the coincidence between the selected body type and the actual body type was tested; the body composition was measured by dual-energy absorptiometry (DXA), and the structure validity of the image was tested; the body size satisfaction was investigated by the body image stimuli and the standard questionnaire, and the empirical validity of the image was tested. The repeated survey was conducted 14 days after the initial survey, and three experts were invited to score the current somatotype of the subjects to test the test-retest reliability and inter-rater reliability of the body image stimuli. Pearson, Spearman, Kendall correlation and Kappa consistency analysis were used to evaluate the validity and reliability of the body image stimuli.Results:The average age of 42 subjects was 52.7 years old, including 13 males and 29 females. A group of three-dimensional body image stimuli of middle-aged men and women were developed, and each group included 8 images. 73.8% of the subjects chose the body size consistent with the actual body type, and the weighted Kappa coefficient was 0.755 ( P<0.01). The selected somatotype was positively correlated with body weight and body composition indexes such as fat content, and the Pearson correlation coefficient of construct validity was 0.623-0.717 ( P<0.05). The results of the two surveys were positively correlated, and the Spearman correlation coefficient of test-retest reliability was 0.784-0.821 ( P<0.05). The scores of the three experts on the current somatotype of the subjects were positively correlated, and the Kendall correlation coefficient of inter-rater reliability was 0.818-0.878 ( P<0.05). Conclusion:The development of principle and reference basis of three-dimensional body image stimuli of middle-aged people is reliable, and the validity and reliability of the body image stimuli are good.

Objective To screen out significant differential genes for predicting the effect of neoadjuvant chemotherapy (NAC) and select the most suitable breast cancer patients for NAC. Methods A total of 60 breast cancer patients' samples before and after NAC were collected for high-throughput RNA-Seq. We selected AHNAK, CIDEA, ADIPOQ and AKAP12 as the candidate genes that related to tumor chemotherapeutic resistance. We analyzed the correlation of AHNAK, CIDEA, ADIPOQ, AKAP12 expression levels with the effect of NAC by logistic regression analysis, constructed a prediction model and demonstrated the model by the nomogram. Results AHNAK, CIDEA, ADIPOQ and AKAP12 expression were up-regulated in the residual tumor tissues of non-pCR group after NAC(P < 0.05). Compared with pCR group, non-pCR group presented higher expression levels of AHNAK, CIDEA, ADIPOQ and AKAP12 (P < 0.05). The high expression levels of AHNAK, CIDEA, ADIPOQ and AKAP12 significantly reduced the pCR rate of NAC for breast cancer (P < 0.05). Our prediction model which AHNAK, CIDEA, ADIPOQ and AKAP12 were involved in showed a good fitting effect with H1 test (χ²=6.3967, P=0.4945) and the ROC curve (AUC 0.8249, 95%CI: 0.722-0.9271). Conclusion AHNAK, CIDEA, ADIPOQ and AKAP12 may be novel marker genes for NAC effect on breast cancer. The efficacy prediction model based on this result is expected to be a new method to select the optimal patients of breast cancer for neoadjuvant chemotherapy.

Objective: To investigate the total amount and types of fluid intake among college students in Hebei Province during spring and to provide scientific basis for fluid-intake education. Methods: A simple random sampling method was used to select 156 college students from a college in Hebei Province. The information on amount and type of fluid intake was recorded using the 7-day 24-hour recording method. A separate analysis was performed on people who consumed beverages during the 7 days. Results: The median intake of plain water, milk, sugar-sweetened beverages and other beverages was 866 mL, 43 mL, 43 mL and 2 mL, respectively. The median of plain water, milk, sugar-sweetened beverages and other beverages by the beverage-consumers was 845 mL, 36 mL, 63 mL and 11 mL, respectively. The intake of plain water and sugar-sweetened beverages in male students was significantly higher(Z=2.31, 3.03; 2.31, 2.11, P<0.05), and milk consumption was lower than female students of these two groups of people(Z=-2.73, -2.23, P<0.05). The intake of other beverages in male students was higher than that of female students, but only significant among beverage-consumers(Z=3.31, P<0.01). There was no significant difference in the total amount of different fluid types among different BMI(P>0.05). Conclusion College students in Hebei Province mainly drink plain water. Sex difference is observed in the types of fluid intake.

Objective: To investigate students’ satisfaction on school feeding program in 8 cities in China, and to provide the basis for improving school feeding management and lunch quality. Methods: Multi-stage random cluster sampling method was used to randomly select the second, fifth and eighth-grade students from 67 primary and middle schools in 8 cities including Beijing, Shanghai, Harbin, Shijiazhuang, Guangzhou, Changsha, Bengbu and Pinghu. Results: A total of 15 475 students participated in the survey, 15 170(98.0%) of which were valid questionnaires. A total of 13 297(87.7%) students had lunch in school. Twenty-six(38.8%), 14(20.9%) and 27(40.3%) schools served lunch by self-run canteens, custody canteens, and food delivery companies respectively. Twenty-one schools provided milk or yogurt for lunch, accounting for 31.3%. The reported rates of very satisfied, satisfied, moderate, dissatisfied, and extremely dissatisfied among students were 40.8%, 28.1%, 20.1%, 7.3%, and 3.6%, respectively. The satisfaction rate of the eighth-grade students was lower than that of the second-and fifth-grade(56.9% vs 77.1% vs 73.5%). The satisfaction rate among students from schools with self-run canteen was higher than that of custody canteens and food delivery companies(73.8% vs 60.5% vs 66.2%). The satisfaction rate of school lunch is highest in dining surrounding (75.3%), followed by amount of meals(71.6%), food hygiene(71.1%), food combination(65.4%), and the appearance of the food(60.5%), and food taste(55.9%). Conclusion The satisfaction rate of students for school lunch was acceptable. The food taste is the main factor for students’ dissatisfaction. Schools should be encouraged to provide lunch in the self-run canteens with tasty food while meeting the nutritional standard.

Objective: To understand nutrition knowledge,related attitude and behavior among primary students in six cities of China, and to provide evidence for nutrition education and intervention strategies. Methods: A multi-stage stratified cluster random sampling method was used to select 12 197 grade 4 and grade 5 primary school students from 72 primary schools in 6 cities of China, whom were administered with a questionnaire survey on nutrition knowledge, practice and practice. Results: Average nutritional knowledge was relatively low (12.0±6.4), practice score was moderate(11.4±2.4), while nutritional attitude was relatively high(17.0±2.4). The nutritional KAP scores of girls were higher than those of boys; the nutritional knowledge and practice scores of urban students were higher than those of suburban students; the nutritional knowledge score of fifth-grade students was higher than that of fourth-grade students(P<0.05). The overall nutritional knowledge awareness rate was 26.1%, with the highest in knowledge of whole grains(73.9%). About 83.5% of the students held positive nutritional attitude, 97.6% considered nutritional knowledge important. The overall rate of healthy eating behavior of students was 88.1%. Most students had breakfast almost every day(88.5%). About 34.9%, 38.0%,46.1% and 50.5% were reported of rarely consumption in snacks, fast food and drinks. Students in urban area and grade 5 were more likely have breakfast. Girls reported higher rates of having breastfast and low consumption of snack food and beverage while boys reported higher consumption of fast food. Students from suburban areas reported high consumption of western fast food but lower beverage(P<0.05). The score of students’ nutritional knowledge was positively correlated to attitude, so as attitude and practice(P<0.05). Conclusion Insufficient nutritional knowledge and unhealthy dietary behavior is observed in primary school students in China. Nutritional K-A-P varies in students with different gender, area and grade. Specific nutritional education in school-setting should be developed accordingly to culture healthy lifestyle among primary school students.

Objective: To understand food intake frequency among primary students in six cities of China, and to provide evidence for nutrition education and intervention strategies. Methods: A multi-stage stratified cluster random sampling method was used to select 12 197 grade 4 and grade 5 primary school students from 72 primary schools in Beijing，Guangzhou,Nanjing,Chongqing,Jinan,Harbin. All the participants were administered with a self-administered questionnaire on dietary behaviors. Results: For the fourth and fifth grade primary school students, the highest proportion of "almost every day" was fresh vegetable(83.2%), and the highest proportion of "nearly eaten" was oat (50.2%). There was a remarkable difference between children of different genders, areas and grades. The intake of whole grains, meat and poultry, fishery products, eggs, soybeans and nutritional supplements of boys was higher than that of girls, while the intake of oats, fresh vegetables, fruits, fungi and algae of girls was higher than that of boys. The intake of oats, vegetables, fruits, fungi and algae, meat and poultry, milk of central urban areas students was higher than that of suburban areas students, while the intake of fishery products, soybeans and nutritional supplements of suburban areas students was higher than that of central urban areas students. The intake of oats, fresh vegetables, fruits, meat and poultry, eggs, milk and soybeans of fifth grade students was higher than that of fourth grade students, while the intake of whole grains, fishery foods and nutritional supplements of grade 4 students was higher than that of grade 5 students. The differences were all statistically significant(P<0.05). Conclusion The frequency of food intake varies among students of different genders, urbanities and grades. School teachers, parents and community workers should make efforts targeting at students with different characteristics to enhance nutritional literacy and cultivate healthy eating behaviors.
