ABSTRACT
Objective@#To investigate the intake of liquid dairy products and identify its influencing factors among the fourth grade students in Nanjing City. @*Methods@#The fourth grade students were selected as the study subjects in Nanjing City using a multi-stage random cluster sampling method in September 2020. Their general information, frequency of liquid dairy product intake one week prior to survey and mean intake amount per time were collected. According to the 2016 Dietary Guidelines for Chinese Residents, weekly intake of liquid dairy products of 2 100 g and greater was defined eligible. Factors affecting the frequency and amount of liquid dairy product intake were identified using multivariable logistic regression analysis.@*Results@#A total of 2 268 questionnaires were allocated and 2 216 valid questionnaires were recovered, with an effective recovery rate of 97.71%. The respondents included 1 199 boys ( 54.11% ) and 1 017 girls ( 45.89% ). The frequency of liquid dairy product intake was (6.41±4.86) times per week, and the median intake amount was 1 250.00 g per week (interquartile range, 1 750.00 g per week). There were 607 students ( 27.39% ) consuming liquid dairy products of 2 100 g and greater a week, and 1 016 students ( 45.85% ) consumed liquid dairy products for 7 times and more a week. Multivariable logistic regression analysis showed that living in urban areas ( OR=1.204, 95%CI: 1.005-1.443 ), knowing nutrition labels ( OR=1.221, 95%CI: 1.021-1.460 ), periodical measurement of body weight (OR=1.486, 95%CI: 1.098-2.011) and restricted intake of sugar-containing drinks ( OR=1.264, 95%CI: 1.005-1.590 ) facilitated the intake of liquid dairy products for 7 times and more a week, and students with periodical measurement of body weight were more likely to consume liquid dairy products for 2 100 g and greater a week ( OR=1.821, 95%CI: 1.240-2.676 ).@*Conclusions@#Inadequate intake of liquid dairy products is found among the fourth grade students in Nanjing City. Residence, awareness of nutrition labels, periodical measurement of body weight, and parental restriction of sugar-containing drink intake affect the intake of liquid dairy products.
ABSTRACT
Objective To investigate the application value of combination of thinprep cytologic test (TCT),human papilloma virus (HPV),c-MYC and human chromosome telomerase gene (hTERC) genes to screen cervical cancer.Methods A total of 230 cases of the study objects was detected with TCT and HP,respectively.Amplification of c-MYC and hTERC genes was tested with fluorescence in situ hybridization (FISH) method.The histopathological results were the gold standard,and the sensitivity,specificity and accuracy of cervical intraepithelial neoplasia (CIN) Ⅱ / Ⅲ and squamous cell carcinoma (SCC) were compared with the four combined detection.Results Of 230 screened patients,there were 124 cases of TCT positive,155 cases of HPV positive,c-MYC gene amplified in 118 cases,and hTERC gene amplified in 128 cases.When TCT,HPV,c-MYC,and hTERC were used alone,the highest sensitivity was HPV (84.5％),the highest specificity was c-MYC (97.6％),and the highest accuracy was hTERC (85.2％).When the three indexes were used in coordination with each other,the sensitivity and accuracy of TCT + HPV + hTERC were the highest (98.6％ and 90.9％),and the specificity of TCT + c-MYC + hTERC was the highest (79.3％).When the four indexes were used together,the sensitivity was 98.6％,the specificity was 72.0％,and the accuracy was 89.1％.Conclusions Combined examination can improve the sensitivity and accuracy of screening cervical lesions,and the three combination of TCT + HPV + hTERC had the best effect,and c-MYC gene detection had the highest specificity.
