ABSTRACT
Objective To investigate the occurrence situation and related influencing factors of obesity among children aged 6-17 years old in Chengde City.Methods The random sampling method was adopted to extract 16 811 children from 10 primary and middle schools in urban and rural areas of this city.The physical examinations were carried out.The incidence rates of over weight and obesity in different ages,sexes and areas were calculated.The risk factors for childhood obesity were preliminarily screened through questionnaire.And the Logistic regression analysis was conducted for further analyzing the risk factors for childhood obesity.Results Among 16 811 sampled children,the overweight rate was 13.09％ and the obesity rate was 12.1％.The overweight rate and obesity rate in boys were higher than those in girls;which had no statistically significant difference between urban and rural areas(P＞0.05);the incidence rates of overweight and obesity in adolescence were higher than those in preadolescence.The multivariate Logistic regression analysis showed that parental overweight,like to drink sugary drinks and watching television for long time might be the risk factors for childhood obesity.Conclusion The overweight rate and obesity rate among children aged 6-17 years old in this city are higher.Reasonable diet,correct life style and increasing exercise can partially reduce the incidence of children obesity.
ABSTRACT
Objective To summarize the clinical manifestation ,the main pathogenic bacteria distribution and drug resistance of neonatal community acquired sepsis late onset in our hospital .Methods Retrospectively analyse the clinical material of 122 cases (41 premature cases and 81 cases of full term) with neonatal community acquired sepsis late onset ,which were clinically diagnosed , from January 2009 to December 2012 in our hospital .Results The main clinical manifestation of neonatal community acquired sep-sis late onset was poor response(64 .7% ) ,repellent milk(57 .4% ) ,temperature changes(61 .5% ) ,and the respiratory tract and um-bilical region were the main infection ways .42 cases were checked out with pathogen in the 122 cases ,blood culture positive rate was 34 .4% ,and there was no statistically differences between the premature and the full term infant group ,In the 42 cases ,there were 29 cases with staphylococcus ,including 10 cases of staphylococcus aureus ,14 cases of coagulase negative staphylococcus and 5 cases of enterococcus ;and there were 10 cases are checked out with e .coli .All of the coccus detected were resistant to penicillin and erythromycin ,but sensitive to vancomycin ,teicoplanin ,linezolid .The e .coli was sensitive to amikacin ,imipenem ,meropenem ,and al-so had a higher sensitivity to cefazolin ,ceftriaxone ,cefepime ,cefoperazone and nitrofurantoin .Conclusion Blood culture positive rate is not high in neonatal community acquired sepsis late onset ,and its′clinical manifestations are nonspecific .The main pathogenic bacteria is coagulase negative staphylococcus ,staphylococcus aureus ,followed by escherichia coli .
