PREVALENCE OF ANEMIA AND EFFECTIVENESS OF WEEEKLY IRON SUPPLEMENTATION IN THE PREVENTION OF ANEMIA AMONG INFANTS AGED 9 - 12 MONTHS IN WELL BABY CLINIC, POLICE GENERAL HOSPITAL
Keywords:anemia, iron deficiency anemia, infant aged 9-12 months
Anemia in infants and preschool children is a permanent public health problem of Thailand. The most common causes of anemia are iron deficiency and Thalassemia. The purposes of this retrospective descriptive study were to find out the prevalence and causes of anemia among infants aged 9-12 months who had hematocrit (Hct) screening for anemia in well baby clinic, Police General hospital. Data were extracted from medical records between 1 Oct 2017 to 30 Sep 2018. Also, They were to evaluate effectiveness of supplementation weekly 12.5 mg. oral elemental iron compared with control on prevalence of iron deficiency anemia (IDA) in infants. Anemic infants were followed up in changing of Hct after treatment of iron deficiency anemia. Baseline characteristics of samples were analyzed by using descriptive statistic. The chi-square statistic was used for comparing between two independent groups. Limit for statistical significance was set at .05.
Results showed that 129 out of 550 infants were anemia (23.45 percent). While the cut point of anemic Hct is less than 33%. There were 117 infants to find the causes and follow up. Predominant causes of anemia were iron deficiency and abnormal types of hemoglobin. 62 Infants had iron deficiency anemia (52.99 percent). Infants with IDA were proofed by monitoring the response in increase of 3% in Hct after taking 3 mg/kg/day oral elemental iron for 1-2 months.
There was no statistically significant difference in prevalence of IDA between weekly iron supplemented group and control group (35.29 and 60 % , p = .132) .All infants with IDA were responded to treatment by Hct was increased 4.44±1.42% (M± SD).The results lead to conclude that we should focus on not only awareness of anemia and IDA among infants but also prevention of iron deficiency anemia. The Increase dosage of weekly elemental iron supplementation may be effective in prevention of IDA and reduction in prevalence of IDA. We should recommend earlier about appropriate complementary food for infants that have risk factors of iron deficiency.
