ABSTRACT
Objective To evaluate the changes of smoking related knowledge,attitude and behavior among adult residents and to provide evidence for tobacco control strategy.Methods The adult residents in Shangcheng District were investigated by Multi -stage stratified radom sampling method in 2007,2010 and 2013,and the dynamic status of knowledge,attitude and behavior of smoking were analyzed.Results There were 239,250 and 259 people investigated in 2007,2010,and 2013,respectively.The current smoking rates of the interviewees were 25.52%,22.40%,and 24.71%,and there was no changes during these years(P >0.05).The awareness rates of bronchitis and lung cancer were more than 90%,and the awareness rates of lung cancer increased by years(P <0.05).Family smoking behavior rate decreased from 49.37% to 35.14%.The passive smoking rate decreased from 63.60% to 53.28% (P <0.05 ).The supporting rate of smoking prohibition at 7 public places increased (P <0.05),with the entertainment venues from 71.55% to 84.17% and school, hospital from 87.87% to 98.07%.Conclusion Family smoking rate and passive smoking rate decreased.The supporting rate of smoking prohibition at common area is increasing.
ABSTRACT
Objective To establish the reference intervals of serum pepsinogen(PG)in healthy adults in Changsha area,and to explore their distribution as well as related factors.Methods Serum PGⅠand PGⅡ levels were determined by a latex-enhanced turbidimetric immunoassay method in 1 279 subjects from Changsha area.Then PGⅠ/PGⅡ was calculated.Results The PGⅠ, PGⅡ and PGⅠ/PGⅡ levels of 1 279 healthy adult residents showed a skew distribution.The levels of serum PGⅠand PGⅠ/PGⅡ in males were 62.0 ng/mL and 4.3,which in females were 59.4 ng/mL and 4.1,significantly lower than those in males(P<0.05).Age was significantly positive correlated with serum concentrations of PGⅡ(r= 0.278,P<0.01),and was negative correla-ted with PGⅠ/PGⅡratio(r= -0.173,P<0.01).The normal reference ranges of serum PGⅠ,PGⅡ and PGⅠ/PGⅡ in males were≥56.8 ng/mL,≤22.6 ng/mL,and ≥3.3,respectively,and in females were ≥51.4 ng/mL,≤23.1 ng/mL,and ≥3.0,respec-tively.Conclusion The serum PG levels of healthy adult residents significantly show skew distributions in Changsha area,which are affected by gender and age.The establishment of reference intervals of PG contributes to clinical screening and diagnosis of gas-tric-related deseases.
ABSTRACT
Objective To understand hypertension risk factors among adult residents in Hebei province.Methods The adult residents were selected by multistage stratified sampling,and investigated with the same questionnaires,body measurement,blood pressure measurement,blood sample analysis,to analyze risk factors of hypertension by ?2 with simple factor and by logistic regression with mult-factors.Results The prevalence of hypertension in 4200 adult residents(18-69 ages) was 39.6% and age-adjusted rate was 28.5%.The single factors analysis indicated that the prevalence of hypertension was higher in men than in women,in countryside than in city,and increased with age rising.Its prevalence is correlated with education level,marriage status,occupation,income,smoking,passive smoking,manual activity,eating habits,BMI,waist,diabetes,blood fat,status of spirit and health.Multiple logistic regression analysis indicated that city,female,educational level of senior high school and above that,farm working,eating less brined vegetables is protective factors for hypertension,and their OR(95%CI) were 0.777(0.644~0.937),0.674(0.551~0.823),0.654(0.534~0.801),0.826(0.684~0.997),0.844(0.729~0.977) respectively,and more than 35 ages,not usually eating vegetable,bad status of health by self-sensations,high serum TC and TG,overweight and obesity were the main risk factors for hypertension,and their OR(95%CI) were 4.145(3.263~5.266),4.460(1.049~18.969),1.234(1.068~1.425),1.400(1.200~1.634),1.420(1.074~1.878),1.478(1.235~1.768),1.728(1.448~2.061) respectively.Conclusion The prevalence of hypertension in adult residents in Hebei province was correlated with multi-factors,so complicated prevention and control in hypertension should be reinforced.
