To examine whether the prevalence of childhood anemia in white low-income children has continued to decline into the 1990s.
An examination of 14 years of hematocrit data from the Centers for Disease Control and Prevention's Pediatric Nutrition Surveillance System in Vermont from 1981 through 1994.
Public health clinics for the Special Supplemental Nutrition Program for Women, Infants, and Children in Vermont. The same screening method and criteria for identifying and defining anemia and the same quality-assurance procedures were used during the 14 years. The program eligibility criteria were also consistent except for part of 1991 and 1992.
The annual prevalence of anemia.
Between 1981 and 1994, the prevalence of anemia halved (from 7.9% to 3.6%, P<.001). For children aged 6 to 24 months, this decline was from 7.8% to 4.6% (P<.001); for children aged 2 to 5 years, the decline was from 7.9% to 3.1% (P<.001).
The decline in the prevalence of anemia among low-income children observed by the Centers for Disease Control and Prevention's Pediatric Nutrition Surveillance System up to the mid-1980s has continued into the 1990s in Vermont. This finding indicates that iron nutrition in infancy and early childhood is still improving.
研究20世纪90年代白人低收入儿童中儿童贫血患病率是否持续下降。
对1981年至1994年佛蒙特州疾病控制与预防中心儿科营养监测系统14年的血细胞比容数据进行检查。
佛蒙特州妇女、婴儿和儿童特别补充营养计划的公共卫生诊所。在这14年中使用了相同的贫血筛查方法、识别和定义标准以及相同的质量保证程序。除1991年和1992年部分时间外，该计划的资格标准也保持一致。
贫血的年患病率。
1981年至1994年期间，贫血患病率减半（从7.9%降至3.6%，P<0.001）。6至24个月龄儿童的患病率从7.8%降至4.6%（P<0.001）；2至5岁儿童的患病率从7.9%降至3.1%（P<0.001）。
疾病控制与预防中心儿科营养监测系统观察到的低收入儿童贫血患病率在20世纪80年代中期之前的下降趋势在20世纪90年代的佛蒙特州仍在持续。这一发现表明婴儿期和幼儿期的铁营养状况仍在改善。
