Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013

Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition wasdetermined against WHOs 2006 growth standards.The prevalence in 2013 and 2002 was weighted by China sixth National Population Census (2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wastingbetween 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent totake action to control undernutrition in the vulnerable areas and subgroups.     

云南小磨高速公路沿线施工前疟疾流行现状调查

目的 了解小磨高速公路沿线疟疾流行现状，为制定防护措施提供依据。方法进行沿线居民带虫调查、疟史访问、施工人员带虫调查、两个乡卫生院近2年发热病人疟原虫检出情况及媒介按蚊调查。结果2003～2004年居民及小学生疟史率在12.4％～15.4％之间，平均13．9％；带虫率分别为0.58％（2／345）、0.33％（1／306）。勐仑、磨憨两个卫生院2003、2004年发热病人血检，阳性率分别为5．6％（89／1597）、11.6％（24／207），平均8.3％，其中勐仑乡卫生院来自于内地的流动人口感染疟疾平均65.8％。结论小磨路沿线目前疟疾流行严峻，急待加强施工人群的疟疾防治工作。     

我国东北一个县自然人群糖尿病流行病学调查

按照ＷＨＯ和中华医学会糖尿病学会规定的标准，１９９３年我们对吉林省柳河县进行了糖尿病流行病学调查，发现糖尿病（ＤＭ）及糖耐量低减（ＩＧＴ）的患病率已分别达到４．５２％和２．５３％。城镇ＤＭ患病率（５．３８％）略高于农村（２．３４％）。ＤＭ及ＩＧＴ患病率均随年龄增加而增高。ＩＧＴ患病率与标准体重百分比呈正相关关系，ＩＧＴ组平均标准体重百分数为１１３．６±２３．７％，显著高于对照组（Ｐ＜０．０２）。肥胖组ＩＧＴ患病率高达８．２９％，与非肥胖组（２．４０％）相比亦有增高的趋势。无论男性还是女性，ＤＭ和ＩＧＴ患者的腰／臀比值均显著高于对照组（Ｐ＜０．００１）。ＤＭ和ＩＧＴ患者的血压也明显高于对照组（Ｐ＜０．００１）。按体力劳动强度分组分析，随劳动强度的增加，ＤＭ患病率有减少的趋势。上述结果表明，该县糖耐量异常的比例已达很高的水平，这种情况可能与当地饮食习惯不良、体力劳动过少、腹部型肥胖者比例较大等因素有关。     

天津市城乡居民糖尿病患病情况及其影响因素

目的了解天津市城区和农村的糖尿病的患病情况及其主要的影响因素。方法采用人户调查的方法对被人选的社区开展基线调查,对个体调查对象的一般情况、健康状况、生活方式及行为、营养知识等进行询问调查,并对调查对象进行身高、体重、腰围、臀围、血压、血糖的测量。结果共调查2886人,糖尿病的患病率为8．1％,且存在城乡差异,城市（10．6％）较农村（4．O％）高,不同地区糖尿病的患病率也存在性别和年龄的差异,年龄、BMI、文化程度以及糖尿病家族史为糖尿病的主要影响因素。结论该市糖尿病患病率呈上升趋势,年龄大、超重／HE胖、文化程度低、糖尿病家族史为糖尿病的主要影响因素。
