RESUMO
Objective@#To investigate the prevalence of adolescents dietary behavior in Shanghai, and to explore emotional influence on dietary behavior.@*Methods@#A total of 7 456 students from 10 junior and 6 senior high schools in Shanghai were selected to participate in the questionnaire survey with the stratified random cluster sampling method. The survey included general information, eating behavior, PHQ-2 and GAD-7.@*Results@#During the past week, the proportion of adolescents in Shanghai reported consumption of sugar sweetened beverages, sweet desserts, frequent fried food and fast food (≥4 times/week) were 13.26%, 16.90%, 6.99 % and 13.01%, respectively. The proportion of students reported consumption of fruits, vegetables, milk and breakfast every day were 56.96%, 73.00%, 65.03% and 76.11%, respectively. There were significant differences by sex and educational stages(both P <0.05). Adolescents with depression or anxiety have a higher incidence of unhealthy eating behaviors than those without depression or anxiety( P <0.01). After adjusting for gender, school, accommodation, grades, pocket money and social class, depression and anxiety increase the risk of various unhealthy eating behaviors in adolescents( P <0.05). Compared with those without anxiety, the risks of sugar sweetened beverages consumption (≥1 time/d) among adolescents with mild and moderate to severe anxiety were 1.42 times (95% CI =1.20-1.67) and 2.51 times (95% CI =2.09-3.01), the risks of insufficient fruits consumption (<1 time/d) were 1.30 times (95% CI =1.16-1.45) and 1.28 times (95% CI =1.11-1.47), the risks of insufficient vegetable consumption (<1 time/d) were 1.35 times (95% CI =1.20-1.52) and 1.41 times(95% CI =1.21-1.65), the risks of insufficient milk consumption (<1 time/d) were 1.29 times (95% CI =1.15-1.44) and 1.20 times(95% CI =1.04-1.39), and the risks of breakfast skipping were 1.75 times (95% CI =1.54-1.99) and 2.97 times (95% CI =2.55-3.46) among adolescents with mild and moderate to severe anxiety.@*Conclusion@#The proportion of unhealthy eating behaviors among adolescents in Shanghai is still high. Early education and intervention for students eating behaviors should be carried out, and attention should be paid to the occurrence of adolescents negative emotions, so as to reduce the risk of unhealthy eating behaviors among adolescents through the promotion of mental health.
RESUMO
Objective To evaluate the clinical efficacy of gemcitabine plus cisplatin (GP) regimen and paclitaxel plus cisplatin (TP) regimen in the treatment of recurrent or metastatic nasopharyngeal carcinoma.Methods One hundred and thirty patients with recurrent or metastatic nasopharyngeal carcinoma of Qinhuangdao Harbor Hospital,Hebei Province between September 2012 and December 2017 were chosen,and were divided into GP group (68 cases) and TP group (62 cases)according to the selection of treatment.GP group was treated with GP regimen,and TP group was treated with TP regimen.The clinical efficacy and adverse reactions of the two groups were observed,and the serum epithelial cadherin (SE-CAD) and platelet-derived growth factor (PDGF-BB) were measured before and after chemotherapy.Results There was no significant difference in short-term efficacy between GP group and TP group (P＞0.05),and the total effective rates were 88.24％ (60/68) and 79.03％ (49/62) respectively;1 month after treatment,SE-CAD in GP group and TP group were (2.57 ± 0.81) and (2.50 ± 0.96) g/L,PDGF-BB were (102.22 ± 31.18) and (110.15 ± 37.21) ng/L,and the difference was not statistically significant (P＞0.05);progression-free survival (PFS) in GP group and TP group were 13 and 12 months,and overall survival (OS) were 17 and 16 months,and the difference was not statistically significant (P＞0.05);there were no significant difference in leucopenia,hemoglobin,thrombocytopenia and abnormal liver and kidney function between GP group and TP group (P＞0.05);the incidence of gastrointestinal reactions in GP group was 16.18％ (11/68),which was significantly lower than that in TP group was 38.71％(24/62),and the difference was statistically significant (P＜0.01).Conclusions GP and TP regimens are effective in the treatment of recurrent or metastatic nasopharyngeal carcinoma.There is no significant difference in SE-CAD and PDGF-BB levels between the two regimens after treatment,but GP regimen has a lower incidence of gastrointestinal reactions.
