ABSTRACT
Objective To explore the main risk factorrelated to the incidence of chroniobstructive pulmonary disease (COPD) among Chinese people in mainland so ato provide the basifothe decision making on COPD prevention .MethodEighpublished literatureof case-control studieon the risk factoof COPD were collected and analyzed quantitatively and synthetically by the metanalysi;the RevMan 5 .2 software waadopted to perform the consistency tesand calculate the pooled oddradio (OR) value and 95% CI .The risk factorwith the Ovalue＞1 were performed the calculation of population attributable risk pro-portion(PARP) .ResultThe pooled oddradio value,95% CI and PARP were smoking OR= 2 .12(1 .58 -2 .86) ,PARP=28 .16% ;occupational exposure OR=1 .82(1 .04-3 .18) ,PARP=11 .60% ;family history of respiratory disease OR=1 .82(1 .36-2 .44) ,PARP=14 .25% ;coal and biomasfuel focooking and heating OR=3 .29(1 .01-10 .67) ,PARP=41 .29% ;low body masindex OR=2 .58(1 .78-3 .74) ,PARP=5 .71% ;low educational degree OR=1 .24(1 .02 -1 .50) ,PARP=12 .93% ;history of re-currenrespiratory tracinfection during childhood OR= 2 .10 (0 .99 -4 .47 ) ,PARP= 13 .39% ;passitive smoking OR= 1 .00 (0 .89-1 .11) .Conclusion Smoking ,occupational exposure ,family history of respiratory disease ,coal and biomasfuel focooking and heating ,low body masindex ,low educational degree and history of recurrenrespiratory tracinfection during childhood are the risk factorinfluencing the incidence of COPD among Chinese people in mainland .
