ABSTRACT
Objective To understand the epidemic status quo and influencing factors of Kashin-Beck disease among children in mountain areas of Jilin Province.Methods Two hundred eighty-two severe endemic areas in 18 counties were selected and stratified by random cluster sampling method,and the status quo of KashinBeck disease prevalence was investigated among 7-12 year-old children according to the Diagnostic Criteria of Kashin-Beck Disease (WS/T 207-2010).In the meantime,the annual household income and the proportion of economic crops replanted,grain out-sourced,and returning farmlands to forests and grass were surveyed in the disease affected areas.Results A total of 14 162 children were investigated who had no clinical symptoms.Among them,28 cases were detected positive using X-ray with a detection rate of 1.98‰,while most of the cases were metaphysis positive.The annual household income (≥5 000 Yuan vs.< 5 000 Yuan) in the year 2009-2011 had a significant impact on the incidence of Kashin-Beck disease (1.47‰ vs.3.67‰,x2 =6.179,P < 0.05),while the areas of returning farmland to forests and grass which accounted > 1% had no significant influence on the incidence compared with that ≤ 1% (3.30‰ vs.1.57‰,x2 =3.876,P > 0.05);the areas of economic crops replanting which accounted > 10% had no significant influence on the incidence compared with that ≤ 10% (3.07‰ vs.1.65‰,x2 =2.565,P > 0.05);the proportion of grain out-sourcing which accounted > 50% had no significant influence on the incidence compared with that ≤50% (3.07‰ vs.1.65‰,x2 =2.565,P > 0.05).Conehision Up to 2012,the disease among 7-12 year-old children of the mountain areas of Jilin Province have basically met the standard of Kashin-Beck disease elimination and the situation remains stable;furthermore,the household income has a significant impact on the incidence of Kashin-Beck disease.
