ABSTRACT
High blood pressure in children, especially in developing countries is growing. Birth weight, age and anthropometric parameters such as current height and weight as factors in childhood hypertension and adolescents have been considered. The objective of this study was to evaluate the prevalence of hypertension in children school and it's correlation with birth weight and current height and weight. In a cross-sectional study, between 2006-2008 among 1195924 students in Tehran's schools, 2040 individuals were selected by multistage random sampling method. Inclusion criteria were age 6 to 19 years, physical health and having health card. The twins, students with hypertensive and smoker mothers were excluded. Statistical analysis was conducted by SPSS software version 16. The multiple regression analysis equation was used to determine the predictors of blood pressure levels. 69 students [3.4%], including 4.84% of girls and 3.5% of boys had high blood pressure [p=0.14]. Significant direct correlation between age, current weight, current height, and body mass index, systolic and diastolic blood pressure was found. However, birth weight has a weak reverse linear correlation with systolic and diastolic blood pressure [respectively=-0.152 and r=-0.111, p<0.001]. Attention to Current size, especially Current weight with consideration to birth weight can be helpful to predict blood pressure in adulthood. This is important in monitoring the weight and blood pressure in children, especially child with an abnormal birth weight and overweight children
ABSTRACT
The operating room is one of the main units in a hospital, where the most important phase of treatment is performed. Due to the physical properties, use of gases, and different electric devices in the operating room, the safety of both the patients and the staff should be considered carefully. This study aims to estimate the safety standards of the operating rooms in Tehran University Hospitals and to provide solutions to the existing problems. This is a descriptive, cross-sectional study conducted in the operating rooms of TUMS hospitals. The research instrument was a checklist used by interviewers while observing the place. The safety standards were studied in terms of physical environment, protection against fire, personnel safety, patients' safety, and infection control. The data were analyzed by SPSS software. The overall safety of the operating rooms of TUMS hospitals was found to be 84.9 percent. The figures for infection control and personnel safety, however, were lower. The operating rooms of Tehran University of Medical Sciences hospitals were studied in terms of five safety standards. Considering the physical environment, fire protection, and patient safety, they were quite safe but as to infection control they were relatively safe. However, they were found to be unsafe regarding the safety of their staff. Tehran Heart Center with an overall safety of 97.5% for its operating rooms can be considered as a model for the other TUMS treatment centers
