Anaemia is a major public health problem in preschool-age children because it is associated with an increased risk of death, impaired cognitive development, growth and immune function. 6 Based on recent estimates from the World Health Organization (WHO 2008) the prevalence of anaemia is 24.8% globally and the highest rates are found in preschoolage children (67.6%) and pregnant women (57.1%) in subSaharan Africa. Of the 293.1 million children who suffer from anemia worldwide, 83 million (28%) are in sub-Saharan Africa, (McLean et al., 2009; WHO, 2008) 7 World Health Organization (WHO) recommends exclusive breastfeeding for 6 months. In Kenya EBF is low 32%. However, IDA is still of concern to EBF infants .(Beard 2007). The introduction of complementary foods is not accepted before 6 months. There is evidence that even children with normal birth weights, but anemic mothers, will have low iron reserves at birth and are more likely to develop anemia (Fall 2004). 8 Current guidelines for iron supplementation in young children are based on the assumption that: However, it depends on factors not often present in low-income countries: adequate maternal iron status, low birth weights, adequate birth practices that promote the transfer of a portion of the birth iron via placental blood i.e (late umblical code clamping) and Exclusive breast-feeding that avoids pathological iron loss via damage to the integrity of the intestinal wall. (Chaparro ,2006). 9 The iron content of human milk is low (0.4-0.8 mg/L in colostrum and 0.2-0.4 mg/L in mature milk and decreases with the length of lactation. In addition, introducing CF during the first 6 months of life can hinder absorption of the iron present in breast milk. Therefore Iron deficiency has been described as the most common nutritional deficiency in the world. In a survey of 858 children 6-35 months of age in western Kenya, Anemia (71.8%) and severe anemia (8.4%) were common. Overall 16.8% of anemia cases were associated with malaria, 8.3% with iron deficiency, and 6.1% with inflammation (Foote EM 2013). 10 By the fourth month of age, neonatal iron stores are reduced by half, and exogenous iron is required to maintain the Hb during the rapid phase of growth above 4 months of age. Hence the reason of carrying the study on this 3-6 m infants. Further, deficiencies are associated with adverse effects on child cognitive, compromised immunity and motor development among other defects. (WHO 2006) recommends iron supplementation for anaemic. 11 Hence this study is designed to assess the iron status and the nutritional status of infants 3-6 months in Mama Lucy Kibaki Hospital It will provide baseline information for an intervention to address anaemia in either exclusively, partially or mixed breastfed infants. 12 It is meant to help implement effective measures for fighting iron deficiency anaemia in infants below 6months 1.5 Purpose of the study Generate information on prevalence of Iron deficiency anaemia in infants 3-6 months and its association with breastfeeding type in order to inform appropriate interventions. To establish other factors associated with Iron Deficiency Anaemia in infants 3-6 months. 13 To assess the hemoglobin concentration in relation to breastfeeding type and other associated factors among 3-6 months old infants. 1.6.1 Sub objective 1) To determine socio-economic and socio-demographic characteristics of study population. 2) To determine infant feeding practices i.e. if exclusive, partial or mixed breastfed. 3) To determine maternal and infant nutritional status 4) To determine the haemoglobin concentration in infants 3-6 months old. 5) To determine morbidity experience of the children 14 Breastfeeding types and maternal nutritional status influence the iron status of infants 3-6 months The morbidity experience, economic and socio demographic characteristics are related to the child's development of Iron Deficiency Anaemia. 1.8 Assumptions mothers will be willing to participate Will receive ethical clearance from KNH 15 The study will provide information on the iron status of infants to researchers as a reference for subsequent studies. The findings of this study can help relevant agencies like the policy makers, Ministry of Health in setting up interventions to curb iron deficiency anaemia. The study will contribute to information aimed at imparting knowledge to mothers on prevention of IDA and promotion of proper Exclusive Breastfeeding. 16 CHAPTER 2: LITERATURE REVIEW 2.0 INTRODUCTION 2.1 Overview of Infant Nutrition 2.2 Breastfeeding Types Commonly Practiced on Infants 2.2.1 Exclusive breastfeeding 2.2.2 Mixed Breastfeeding 2.2.3 Partial breastfeeding 2.2.4 Breastfeeding in HIV AID Context 2.3 Iron Deficiency and Anaemia in Infants 2.4 Prevalence of Iron Deficiency Anaemia among under five 2.5 Methods of Measuring Iron Status 2.6 Causes of Iron Deficiency and Anaemia in Infants 2.7 Consequences of Iron Deficiency Anaemia in Infants 2.8 Approaches to Ensure Adequate Iron Status in Early Infancy 17 There is inadequate data in the literature on the prevalence of anemia among children less than 6 months old, because of the assumption that at this age breast milk suffices to provide the necessary iron, irrespective of maternal nutritional status. 18 CHAPTER 3 3.0 METHODOLOGY 3.1 Study sitting The study will be conducted at MLKH near Umoja in Embakasi constituency. It’s a district hospital owned by the ministry of health. It’s located on Spine road, Umoja 3, near Kayole off Kang’undo road, Nairobi County, Kenya. Its latitude is 1.27373630S and longitude 36.89934310E. . It’s a new hospital constructed by a China Wiyu company with a bed capacity of 137 beds. 19 It’s a public hospital It’s located in a highly populated area of Nairobi serving an estimated population of two million people. It began limited operations in 2011 The hospital was officially opened on February 26, 2013 by his Exellence the former President of Kenya Mwai Kibaki. Mr Zacharia Lihumbazi the human resources manager indicated that the facility handles up to 800 outpatients in a day, 6,000 maternity deliveries. Other departments 20 The (MCH) usually receives around 300 mother-child pair daily. Most of these children are below 9 months. Those attending this well baby clinic range from the high to middle and the low income households which include: Kayole, Sinai, Mwiki, Kasarani, Buruburu, Dohnholm, Greenspan, Umoja and as far as Pipeline estates. 21 The population to be studied will be drawn from the mother child pair visiting the hospital. It will comprise of children 3-6 months both female and male and their mothers. The ethnicity, and the estate they reside in will not be a factor in determining who to assess. 3.3 Study Design A cross-sectional survey involving both descriptive and analytical It will consist of some retrospective components 3.4.1 Sample Size Determination Sample size determination will be using the Fisher et al., (1991) formula N = Z2pq d2 p- 19.1%. According to a micronutrient report on a survey conducted in Kenya in 1999 by the Micronutrient Initiative and UNICEF, q- Expected proportion expected to anaemic (1-p) (1-0.19) =0.81 z- The standard normal deviation set at 1.96 of the 95% confidence interval. d- The degree of accuracy desire set at 0.05 significance. Therefore N= (1.96)2(0.19) (0.81)/ (0.05) 2=236 infants 3-6 months. (Fishers et al, 1991). 23 Nairobi County Purposive Sampling Purposive Sampling Mama Lucy Kibaki Hospital Stratified Sampling Exclusive Breastfeeding Mixed Breastfeeding Partial Breastfeedin Proportionate Sampling 78 Mother Child Pair Systematic Sampling n=78 56 Mother Child Pair n=56 102 Mother Child Pair n=102 24 3.5.1 Data collection tools 1. A semi structured pre-tested questionnaire, contents a. General questionnaire for socio-demographic and socio-economic information of the households. b. Index child information inclusive of breastfeeding types, CF practises, morbidity experience, Hb levels and anthropometric measurements. c. Maternal nutrition status, iron supplementation status during pregnancy, incidences of anaemia and the birth process like the length of time that elapsed before the umbilical cord was clam 2) A food frequency questionnaire for partially breastfed infants. 3) A Key Informant interview guide to interview the head nutritionist 25 Five research assistants will be recruited. Four of them holders of a nutrition certificate, diploma or degree while the other one will be a lab technicians. They should be able to speak fluent English and Kiswahili. They will be trained for 1 day to equip them with knowledge on how to administer and fill questionnaires also taking of anthropometric measurements. 26 Pretesting will be carried out at Kangemi Health Center, targeting at least 10 mother child pair and the information collected will be used to modify questions so as to give the desired results. 3.5.4 Data collection procedures and methods Activities…. Equipments to be usedHaemocue Anlyzer, Adult Muac Tapes, Stadiometer, electronic scales, bathroom scales, height boards, Salter scales and 27 The permission to carry out the study will be sought from KNH/UON-Ethics and Research Committee. To minimize the discomfort and inconveniences the survey team will explain the objectives, purposes, and possible benefits of the study in a The participant will be given an opportunity to ask questions and decline participation or participate by signing a consent form. Safety of the child will be assured by providing adequate procedures. Confidentiality and privacy will be maintained and the caregiver will be assured of this. 28 Calibration Frequent of scales was done on a daily basis. supervision of the assistants during data collection was carried out. The completed questionnaire was cross-checked & examined. Data cleaning to remove extreme & wrong entries was done Field assistants will receive proper training to avoid errors in recordings. To avoid parallax during reading of measurements an average of two subsequent readings will be taken. 29 The Chi-square test will be used to determine the difference between proportions, odds ratios so as to estimate the relative risk. Correlation will be used to test the strength of the association and estimate the relation between variables that contribute to development of iron deficiency and anaemia in infants 3-6 months. The qualitative and quantitative data obtained will be entered and analyzed using specific computer packages namely (ENA) for SMART (SPSS) and nutrisurvey. Data on Key Informant interview will be analyzed using word-processing functions with features of special-purpose software designed coding and creating themes. Available errors during data entry will be noted and counterchecked using the questionnaires. 30 OBJECTIVE VARIABLES DESCRIPTIVE ADVANCED STATISTICAL STATISTICAL TEST TESTS Demographic characteristics Age ,Gender, etc Proportions Infant feeding practices EBF,Partial BF Means,Odds,Per and Mixed BF centages, Nutritional status of index child and the mother Current Height Percentages, Correlation and Weight Modes, Means or Regression Median Prevalence of Anaemia in Infants Hb Means,Odds Chi square tests Chi square, Correlation Regression, Correlation 31 Beard J ( 2007).
