The prevalence of developmental dysplasia of the hip (DDH) is unknown in China. We aimed to determine the prevalence of DDH in Chinese adults.
In this study, we performed a cross-sectional survey of a nationally representative sample of Chinese adults. All participants underwent questionnaire investigation, physical examination, and X-ray examination. Factors associated with DDH were analyzed with logistic regression.
We invited 29,180 individuals aged 18 years and over to participate, randomly selected from 18 primary sampling units (street districts in urban areas and townships in rural areas). The survey and examination were completed in 25,767 people (10,296 men and 15,471 women). DDH was diagnosed in 391 people, yielding an overall DDH prevalence of 1.52%. Based on this information, we estimate the number of individuals with DDH in China to be approximately 16.05 million. DDH prevalence increased with age (odds ratio = 1.53 [1.03-2.27], P = 0.036), was significantly higher among women than men (2.07% vs. 0.75%, P< 0.001), and was higher among rural residents than urban residents (1.75% vs. 1.29%, P< 0.001). Economic development was independently associated with the presence of DDH. There was no evidence of an association between body mass index alone, education, or current smoking or drinking and risk of DDH (P > 0.05).
DDH has become an important public health problem. Special attention should be paid to residents with DDH. Screening for DDH should be performed in China.
中国髋关节发育不良（DDH）的患病率尚不清楚。我们旨在确定中国成年人中DDH的患病率。
在本研究中，我们对具有全国代表性的中国成年人样本进行了横断面调查。所有参与者均接受问卷调查、体格检查和X线检查。采用逻辑回归分析与DDH相关的因素。
我们邀请了从18个初级抽样单位（城市街道和农村乡镇）随机选取的29180名18岁及以上的个体参与研究。25767人（10296名男性和15471名女性）完成了调查和检查。391人被诊断为DDH，总体DDH患病率为1.52%。基于此信息，我们估计中国DDH患者人数约为1605万。DDH患病率随年龄增长而增加（优势比=1.53[1.03 - 2.27]，P = 0.036），女性显著高于男性（2.07%对0.75%，P<0.001），农村居民高于城市居民（1.75%对1.29%，P<0.001）。经济发展与DDH的存在独立相关。没有证据表明仅体重指数、教育程度、当前吸烟或饮酒与DDH风险之间存在关联（P>0.05）。
DDH已成为一个重要的公共卫生问题。应特别关注DDH患者。中国应开展DDH筛查。
