RESUMEN
Objective@#To analyze the total fluids intake and sources of college students from Hebei in spring and summer, and to provide a scientific reference for appropriate fluids intake in different seasons.@*Methods@#Subjects were recruited in a university in Baoding, Hebei Province, and investigations were conducted in April and June 2021. The number of people who completed both spring and summer investigations was 80. Quantitative instruments and 7 day 24 h Fluid Intake Questionnaire were used to investigate the total drinking fluids, and it was recorded for 7 consecutive days in spring and summer respectively. The duplicate portion method was used to investigate the water from food. The total fluids intake and sources among subjects were analyzed in spring and summer.@*Results@#There was no statistical significance between the total drinking fluids and total fluids intake between spring and summer [1 141(715), 1 176(649)mL/d, (2 496±604)(2 458±554)mL/d] ( F=1.86, 0.59, P >0.05). Spring showed significantly higher water from food compared with summer [(1 318±274)(1 217±302)mL/d]( F=16.63, P <0.05). The proportions of total drinking fluids and water from food in spring were 46% and 54%, respectively, and both were 50% in summer, the differences were statistically significant ( F=12.97, 12.97, P <0.05). There were differences in total fluids intake,total drinking fluids and water from food of different genders in earch season ( t/Z =4.75, -3.63, 3.44; 4.80, -2.91, 4.01, P <0.05). There were differences in total water intake, total drinking fluids, the proportions of total drinking fluids and water from food of different BMI groups in each season ( F/H =8.08, 16.65, 3.03, 3.03; 7.11,17.97, 4.52, 4.52, P <0.05). In spring, only 13.8% of subjects achieved the recommended total drinking fluids of China, compared with 18.8% in summer. In spring and summer, the total fluids intake, total drinking fluids, the proportions of total drinking fluids in the group achieved the recommendation were all higher than those who did not reach the recommendation ( t/Z =6.64, -5.19, 5.79; 8.12, -5.97, 5.70, P <0.05).@*Conclusion@#Season is a factor that affects total fluids intake, and it should be taken into account when setting the recommendation on adequate water intake.
RESUMEN
Objective@#To investigate the status of immunization of National Immunization Program (NIP) and its adverse reaction rate in children with tuberous sclerosis.@*Method@#Questionnaire survey was adopted to identify the vaccination coverage and its adverse events; 72 cases of children with tuberous sclerosis and 78 normal controls (healthy children completing age-appropriate NIP) admitted to Chinese People′s Liberation Army General Hospital from December 2014 to November 2015 were involved into this study.@*Result@#The age-appropriate NIP coverage rate of tuberous sclerosis was 36%(26/72). The coverage rate of bacillus calmette-guerin (BCG), hepatitis B vaccine 1st to 3rd doses (HepB1-3), oral poliovaccine 1st dose (OPV1), diphtheria, pertussis and tetanus 1st dose (DPT1), DPT1-3, meningococcal polysaccharide vaccine group A (MPVA), measles amd rubella vaccine/measles vaccine 1st dose (MRV/MCV1), and Japanese encephalitis vaccine 1st dose (JEV1) were 100%(72 cases), 75%(51 cases), 97%(66 cases), 91%(62 cases), 82%(56 cases), 66%(45 cases), 69%(42 cases), and 61%(37 cases) respectively. The reasons why the children did not complete the vaccination plan were that parents were concerned about vaccination-induced seizures or seizures had not been controlled. Among 72 children with TSC, the rate of adverse events or suspected adverse events after vaccination was 17% (12 cases), which was higher than the normal control children (2 cases, 3%) (χ2=8.799, P<0.05). The main adverse events were seizure events, which accounted for 92%(11 cases).@*Conclusion@#The age-appropriate NIP coverage rate among children with tuberous sclerosis is low. The high incidence of adverse events may be associated with a fact that there are some nervous system abnormalities in cases with tuberous sclerosis. TSC children vaccination is relatively safe, with no serious adverse events.
