目的 探究孕期母亲缺铁性贫血与子代孤独症谱系障碍(ASD)结局的关联,为ASD的早期预防及干预提供思路。方法 于2018-2020年采用病例对照研究,选取ASD儿童145名(病例组)与 正常儿童251名(对照组)纳入研究。采用调查问卷收集儿童及母亲一般情况及母亲孕期缺铁性贫血暴露等情况,采用单因素及多因素Logistic回归分析母亲孕期缺铁性贫血暴露与子代ASD发病的风险。进一步采用中介分析探索产儿科不良结局如剖宫产、早产、低出生体重在母亲孕期缺铁性贫血与子代ASD风险关联中的中介作用。结果 ASD 组母亲孕期缺铁性贫血发生率高于对照组(21.31% vs. 7.56%,P<0.001)。单因素Logistic 回归分析显示母亲孕期缺铁性贫血是子代发生ASD 的危险因素(OR=3.31,95%CI:1.73~6.32)。在校正了儿童性别、母亲学历、母亲被动吸烟及孕早期营养素补充后,多因素Logistic回归分析结果趋势未发生改变(OR=3.44,95%CI:1.53~7.71)。本研究未见剖宫产(间接效应 OR=0.99,95%CI:0.94~1.05)、早产(间接效应OR=1.00,95%CI:0.95~1.08)、低出生体重(间接效应 OR=0.99,95%CI:0.94~1.04)在母亲缺铁性贫血和子代ASD发生风险中存在中介作用。结论 母亲孕期缺铁性贫血是子代发生ASD的独立危险因素。孕期缺铁性贫血的早期筛查、早期干预十分必要,可减少子代ASD的发生风险。 相似文献

目的 探讨围孕期环境暴露因素与先天性心脏病(CHD)发生风险之间的关系.方法 采用1∶2配比的病例对照研究方法,于2012年1月至2014年1月对武汉市某区妇幼机构儿童进行“CHD免费筛查”,通过常规听诊、超声心动图初筛,并经市级以上医院确诊.以CHD患儿为病例组,按照年龄、性别、社区配对选择健康的儿童为对照组.用EpiData 3.1软件录入数据,用SPSS 11.5软件进行单因素和多因素的条件logistic回归分析.结果 采集138名患儿和276名对照儿童的父母信息.对27个主要研究因素进行单因素条件logistic回归分析.结果显示,孕早期补钙、孕早期精神刺激、母亲孕期营养、不良孕产史、经产妇、围孕期患病及居住地附近有污染企业与子代CHD发生有一定关联;多因素条件logistic回归分析显示,孕早期精神刺激(HR=3.35,95%CI:1.28 ~ 8.79)、母亲孕期营养不良(HR=1.50,95%CI:1.10 ~ 2.03)及不良孕产史(HR=1.62,95%CI:1.03 ~ 2.57)是子代发生CHD的危险因素,而孕早期适当补钙(HR=0.40,95%CI:0.25~0.65)则可降低CHD发生的风险.结论 CHD的发生可能与孕早期精神刺激、围孕期营养、孕早期补钙及既往不良生育史有一定关系,应加强围孕期保健,降低CHD的发病率. 相似文献

目的 探讨父母亚甲基四氢叶酸还原酶(MTHFR)基因C677T、胱硫醚β-合酶(CBS)基因T833C、环境因素与子代先天性心脏病(CHD)发生之间的关联。方法 采用1:1配对病例对照研究方法,分析115对CHD患儿与对照儿父母的环境暴露因素,并检测其MTHFR与CBS基因型,对CHD可能的危险因素进行单因素及多因素条件logistic回归分析。结果 母亲怀孕早期接触农药(OR=8.62)、妊娠合并症(OR=2.069)、孕早期感冒(OR=4.125)、孕期情绪状况(OR=4.653)、母亲MTHFR基因677TT型(OR=3.872)共5个因素为予代发生CHD的危险因素。结论 母亲MTHFR基因677TT型与子代CHD发生有关,未发现父母CBS基因T833C与子代CHD存在关联,母亲怀孕早期接触农药、妊娠合并症、孕早期感冒、孕期情绪紧张或忧郁可能增加子代发生CHD的危险。 相似文献

孕母叶酸摄入与MTHFR基因C677T多态性对子代先天性心脏病发病风险研究 总被引:1,自引:0,他引:1
目的 分析孕母孕早期环境高危因素,探讨叶酸摄入与MTHFR基因多态性间交互作用对子代先天性心脏病(简称先心病)发病的影响.方法 通过病例对照研究回顾性分析98例12岁以下先心病患者母亲和101例正常婴儿的母亲(对照组)孕期危险因素暴露水平以及叶酸摄入情况,进一步应用变性液相高效色谱(DHPLC)检测MTHFR基因C677T多态性,并分析其与叶酸摄入的交互作用.结果 经Logistic回归分析,6项因素纳入先心病风险模型,孕母教育程度、没有定期产检、精神紧张、接触化学物质是子代先心病的高危因素,服用叶酸和复合维生素是先心病的保护因素.叶酸补充充足情况下,MTHFR基因各基因型比较,病例组与对照组无统计学差异.将间断服用及未服用叶酸者合并作为叶酸补充不足者,其孕母基因型为CT与CC时发病无统计学意义(P=0.066,OR=2.018,95%CI:0.95~4.285).结论 提高孕母的自我保健意识是减少先心病危险因素暴露的重要措施.怀孕早期孕母叶酸的补充不足可能是导致子代先心病发病风险增高的独立因素,孕母MTHFR基因C677T基因型合并叶酸补充不足可能增加先心病风险.Abstract: Objective To explore the environmental risk factors,periconceptional folate intake and methylenetetrahydrofolate reduetase (MTHFR)gene C667T polymorphism of pregnant women on congenital heart diseases (CHD)in offspring.Methods Retrospective case-control study was carried out to investigate periconceptional folate supplementation and environmental factors in 98 parents with CHD offsprings and 101 parents with normal offsprings.The mothers'MTHFR gene C667T mutation was also identified.The possible risk factors were analyzed by simple and multiple factors Logistic regression methods.Results Six factors were related to the occurrence of CHD in the offspring:education of gestation mother,no prenatal examination,under depressed or nervous condition during pregnancy and maternal exposures to harmful substance;periconceptional folate and compound vitamin supplementation were protection factors.There were significant difference between case and control group in folate supplement(P<0.05).The maternal MTHFR 677genotypes CC and TT in combination with daily folate supplements were associated with no increased risk for CHD in offspring,however in combination with not use of folate a two-fold(P=0.066,OR=2.018,95%CI 0.95-4.285)increased risk.Conclusion Improving self health care of gestational mother is the most important protection measures to avoid the risk factors exposure.Periconceptional folate deficiency may be the independence risk factor for CHD.Periconceptional mother carrying MTHER heterozygote's(CT)genotype in combination with deficiency may increase risk for CHD. 相似文献

Few epidemiologic studies have examined the role of maternal iron status in allergic diseases in offspring and findings have been inconsistent. We used a large birth cohort in Japan to explore the association of the markers for maternal iron status (maternal hemoglobin, hematocrit and dietary iron intake during pregnancy) with allergy development in offspring during early childhood. We analyzed information on children age 0–3 years from the Japan Environment and Children’s Study (JECS). We used logistic models and generalized estimating equation models to evaluate the effect of maternal hemoglobin and hematocrit levels and dietary iron intake on allergies in children. Models were also fitted with propensity score-matched datasets. Data were collected for a total of 91,247 mother–child pairs. The prevalence (95% confidence interval) of low hemoglobin and hematocrit was 14.0% (13.7–14.2%) and 12.5% (12.3–12.8%), respectively. After adjusting confounders, low hemoglobin and hematocrit during pregnancy were not associated with childhood allergic outcomes. Findings from models with propensity score-matched datasets also indicated that children born to mothers with low hemoglobin or hematocrit levels during pregnancy did not have a higher risk of developing allergic conditions at 3 years old. We found no meaningful associations between low energy adjusted maternal dietary iron intake and allergies in children. In conclusion, using birth cohort data, we found no evidence supporting an association of low maternal hemoglobin, hematocrit and low dietary iron intake with allergy symptoms during early childhood. Further studies with more suitable proxy markers for blood iron status are needed. 相似文献
