Abstract

Abstract Background Iron deficiency anemia remains a persistent issue in developing countries, including Indonesia, prompting recommendations for routine iron supplementation. However, supplementation is often provided without prior screening, increasing the risk of unnecessary treatment and potential side effects. Validated, non-invasive screening tools could be especially valuable in these settings. This study aimed to evaluate the validity and reliability of a modified NutricheQ Questionnaire for identifying iron deficiency risk in the Indonesian pediatric population. Method A two-step cross-sectional study was conducted among 300 children aged 1–3 years across Jakarta, Indonesia. The first step assessed the validity of the modified NutricheQ Questionnaire, followed by analysing its correlation with dietary iron intake and serum ferritin level. Validity was assessed through Spearman correlation test. Internal consistency was measured using Cronbach’s alpha, and inter-rater reliability was assessed using Cohen’s kappa. Receiver operating characteristic (ROC) analysis was performed to identify optimal threshold scores based on sensitivity, specificity, and area under the curve (AUC). Results The modified questionnaire demonstrated acceptable construct validity, with Spearman correlation coefficients >0.30 for all items except red meat intake. Inter-rater reliability ranged from fair to perfect agreement (Cohen’s kappa: 0.40–1.00). There was moderate correlation with dietary iron intake (r = 0.39, p < 0.01) and serum ferritin levels (r = 0.29, p < 0.01). The 5-question version had an optimal threshold score of 5, yielding a sensitivity of 80.4% and specificity of 48.3% in predicting iron intake; AUC was 0.709 (CI 95%: 0.648-0.770). A shortened 3-question version with a threshold of 4 maintained the same sensitivity (80.4%) and improved specificity (67.0%) for predicting iron intake (AUC = 0.768; 95% CI: 0.712–0.825), with sensitivity of 71.6% and specificity of 61.5% for predicting low serum ferritin (AUC = 0.682; 95% CI: 0.597–0.758). Conclusion The modified NutricheQ Questionnaire demonstrated good validity and reliability for identifying risk factors of iron deficiency in Indonesian children aged 1–3 years. The shortened three-item version, in particular, shows promise as a non-invasive screening tool for use in low-resource settings.

The prevalence of pediatric anemia in Southeast Asia is 65.5%, equivalent to approximately 115.3 million children. 1 First national data from Indonesia showed a prevalence of 40–45% in children aged 1–5 years old in the year 2007, with even higher rates in rural areas, reaching 75–76%. 2,3 As recommended by the World Health Organization (WHO), iron supplementation is deemed necessary when the national prevalence reaches 40%. 4 Consequently, the Indonesian Pediatric Society recommends iron supplementation for all children, prioritizing those aged 0–5 years without the need for prior screening. 5 The American Academy of Pediatrics (AAP), on the other hand, recommends all babies to be screened and tested to determine Hb concentration by the age of 12 months, with decisions regarding iron supplementation made based on various factors, including exclusive breastfeeding status and the composition of complementary feeding. 6 Whilst iron supplementation without prior screening provides practical benefits, it is important to acknowledge that iron is a potent pro-oxidant which may lead to the formation of free radicals. Some health problems that may rise due to inappropriate iron supplementations are growth problems, increased infection risk, as well as increased mortality and morbidity in malaria endemic areas. 7 – 10 However, confirming iron status needs facilities and funds that may not be available in many areas of developing countries, such as Indonesia. Therefore, the usage of a valid and reliable questionnaire to screen for iron deficiency prior to blood tests can be beneficial to such a population, requiring less funds. In 2010, the NutricheQ questionnaire was developed in Ireland to identify micronutrient deficiency risk factors and dietary imbalances. The questionnaire was tested for its validity by Sjarif in 2011 for the Indonesian population and was found invalid due to the terms used as well as the significant difference in the Indonesian diet from European. 11 Sjarif then modified the questionnaire according to the Indonesian diet. 12 However, the modified NutricheQ has yet to be tested for its validity and correlation with iron intake and ferritin levels, which are the two parameters that provide insight towards adequacy of dietary iron intake and iron storage; often reflecting the state of iron deficiency before anemia occurs. 6 , 13 , 14 Hence, this study aims to test the validity and reliability of modified NutricheQ in identifying iron intake and ferritin levels as iron deficiency risk factors in the Indonesian population. 2 Methods 2.1 Study design This cross-sectional study was conducted in two steps. The first step validated the Modified NutricheQ Questionnaire as a screening tool for iron deficiency anemia and the second step tested the correlation of the questionnaire towards iron intake and ferritin levels, aimed to find the score threshold which gives the best diagnostic value. This study adhered to the Declaration of Helsinki and received ethical approval from The Clinical Ethics Committee of Cipto Mangunkusumo National General Hospital (ref-no: 662/H2.F1/ETIK/2013). Written informed consent forms were provided and signed by all participants. The modified NutricheQ Questionnaire consists of 5 questions, which were modified from the iron-intake related section of the original 12-question NutricheQ questionnaire. The 5 question item included questions on the frequency of formula milk (growing-up milk) intake, chicken or beef liver intake, red meat intake, red-meat based food intake, and egg intake. Each question is scored on a scale of 0 to 2, where a score of 0 indicates higher intake/portion and a score of 2 indicates lower intake/portion (see Supplementary Materials 1 and 2). 2.2 Study population This study took place in 5 integrated service posts (Posyandu) across East and Central Jakarta. Data is sampled from December 2013 to January 2014. The target population for this study is children aged 1–3 years old who fulfilled the inclusion and exclusion criteria. The inclusion criteria were children aged 1–3 years whose parents are literate (able to read and write), permanently reside in Jakarta, and agreed to participate in the study. Children who were severely undernourished, suspected or diagnosed with thalassemia, on a routine iron supplementation of minimal 2 weeks prior participating, erythrocyte sedimentation rate of more than 15 mm, as well as children with acute or chronic infection and history of recent blood transfusion (1 month prior study) were excluded from this study. 2.3 Sample size determination and sampling method Sample size of this study was determined using the 10% rule. As this study was a part of a bigger study of the same questionnaire which included all 12 questions, the sample size was determined by the following formula: N = 12x(10–15) N = 120–180 subjects x 1,3* N = 234 subjects *Dropout rate took into consideration the estimated subjects with ESR > 15 mm/hour to be 30% 15 The researchers rounded up the sample size to 300 subjects which were then recruited in integrated service posts. The integrated service posts were selected using stratified random sampling, while subjects were recruited through consecutive sampling until the minimum required sample of 300 subjects was achieved. For the validity, reliability, and correlation tests, subjects were sampled consecutively, with a total of 30 subjects for the validity and reliability tests and 60 subjects for the correlation test. 2.4 Study timeline and procedures All interviewers and dieticians involved in this study received prior training. All parents or guardians with children aged 1–3 years were given explanations on the purpose, procedures, benefits and risks of this study. Prospective subjects who fulfilled the inclusion and exclusion criteria were recruited. Peripheral blood was collected from consenting subjects for hematological profiles and serum ferritin level analyses. All samples underwent processing using consistent machines and techniques. Hematological profiles were analyzed using ADVIA 2120 through flow cytometry, and serum ferritin levels were analyzed using Immulite 2000 through immunochemiluminescent methods. Subjects with erythrocyte sedimentation rates (ESR) ≥ 15mm/hour were excluded from the analysis. Additionally, dietary analysis was conducted for all subjects, involving parents who were asked to maintain a food diary detailing all consumed items over a 72-hour period (2 weekdays and 1 weekend) following the meeting. All parents and/or caregivers received training on maintaining a food diary from the research team. The food diaries were subsequently evaluated and analyzed by dieticians using the NutriSurvey 2007 software. 2.5 Data analysis Data analysis was conducted using the SPSS software. Validity was tested using Spearman correlation test. Internal consistency was measured using Cronbach’s alpha and inter-rater reliability was assessed using Cohen’s kappa. The questionnaire’s level of agreement for iron intake and ferritin level was determined using Pearson correlation test. Diagnostic test was determined using the receiver operating characteristic (ROC) area under the curve. Sensitivity, specificity, positive predictive value, and negative predictive value were also presented in this study. 3 Results 3.1 Validity and reliability of the modified NutricheQ questionnaire First, internal consistency was assessed by calculating the Cronbach’s alpha for the questionnaire. Cronbach's alpha was 0,208. Inter-rater reliability was found to have Cohen’s kappa of 0,4-1. Spearman correlation test showed all questions to be >0,3, except for the question on red meat intake.

All subjects received explanations on good feeding practices and options of iron-rich diet. Children with iron-deficiency anemia as well as non-iron-deficient anemia were referred to be treated in primary healthcare centers or regional general hospitals. Flow diagram on subject’s inclusion and exclusion into the analysis can be found in Figure 3.3 According to the peripheral blood and ferritin analysis, subjects can be categorized into 4 groups: normal iron status, iron deficient, iron-deficiency anemia, and non-iron-deficient anemia (Table 3.3) Table 3.3.

We first identified the threshold score of the modified NutricheQ to predict the risk if inadequate iron intake (<7 mg/day) by calculating the area under the receiver operating characteristic (ROC) curve (AUC). According to the 5 question items, we found an area of 0.709 (CI 95%: 0.648-0.770). In this questionnaire, the lowest and highest score that can be achieved is 0 and 10, respectively. Through sensitivity and specificity tests, we found an optimal threshold score of 5. Table 3.7.1 presents the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of multiple threshold scores in predicting iron intake.

NPV: negative predictive value In regard to serum ferritin level, the AUC was 0.598 (CI 95%: 0.514-0.682). The score 5 showed better diagnostic test results compared to the other prospective threshold (Table 3.7.2).

The total score of the questionnaire in relation to iron intake and ferritin level still showed moderate to strong correlation, with each correlation coefficient to be -0.527 and -0.41, sig(2-tailed) <0.01, respectively. The AUC of the 3 selected questions on iron intake was higher compared to the complete, 5-question Modified NutricheQ Questionnaire: 0.768 (CI 95%: 0.712-0.825) (Figure 3.7.1). The lowest and higher scores of the 3 questions were 0 and 6, respectively. We found an optimal threshold score of 4, which provided sensitivity, specificity, PPV and NPV of 90.4%, 67%, 53.8% and 87.7%. (Table 3.7.3).

The original questionnaire has 4 question items that were correlated to iron intake: age and amount of cow’s milk or formula milk intake, meat or oily fish intake, and fortified cereal intake. 16 , 17 Due to the difference in dietary habits in Indonesia, the questionnaire was found to be inapplicable. Hence, Sjarif modified the questionnaire to better align with the Indonesian population, consisting of question items on formula milk intake, red meat intake, liver intake, red-meat-based food intake and egg intake, as well as providing more understandable terms to describe the portion, based on familiar measurements used by the population. In our study, the Modified NutricheQ Questionnaire has shown to be a valid and reliable tool in assessing iron deficiency risks in toddlers. Most questions exhibited correlation coefficients exceeding 0.3, indicating validity. However, the questionnaire's reliability, measured by Cronbach’s alpha, was 0.208, lower than the study in Ireland, which reported 0.4. 17 Neither the modified nor the original NutricheQ Questionnaire achieved the desired reliability threshold of > 0.6. This discrepancy may be attributed due to the difference in the number of questions. The Modified NutricheQ Questionnaire comprises only 5 questions, while the NutricheQ Questionnaire has 18, allowing for a broader assessment beyond iron deficiency risk factors. Nevertheless, the Modified NutricheQ Questionnaire demonstrated a fair to perfect agreement in inter-rater reliability, with a Cohen’s kappa score of 0.4-1. Amongst all questions in the Modified NutricheQ Questionnaire, only the question on growing-up milk showed statistical significance in its relationship with iron intake. This may be attributed to the question's design, which directly asks respondents for the daily volume in milliliters, potentially reducing recall bias. Even though the questions on liver and red meat consumption weren’t statistically significant, the question utilized a relatively more objective measurement unit compared to other questions. For instance, the questionnaire used a matchbox to describe the portion of red meat, aiding respondents in visualizing their intake accurately. However, red-meat based food, such as sausages, meatballs, and meatloaf, have various unstandardized portions, posing a limitation. Similarly, while eggs are easy to quantify, many mothers prepare eggs alongside other ingredients and often feed multiple children from the same plate at the same time. This may lead to inaccuracies in recalling the amount of egg consumed by a single toddler. Likewise, only the question on growing-up milk has statistical significance in its relation to ferritin levels. However, relying solely on a single question about formula milk consumption to predict iron deficiency would not be able to accommodate children with dietary habits of consuming iron-rich foods without formula milk. The area under the ROC curve for the Modified NutricheQ associated with iron intake and serum ferritin are 0.709 and 0.598, respectively. Threshold score of 5 resulted in optimal sensitivity of 80.4% and optimal specificity of 48.3% when correlated to iron intake. On the other hand, when correlated to serum ferritin, optimal sensitivity and specificity were 73.1% and 43.4%. Ideally, a screening tool should have both sensitivity and specificity of at least 80%. Considering the consistent trend among 3 questions (formula milk intake, liver intake and red meat intake), we conducted a further analysis on the AUC of the 3 questions and compared it to the 5-question set. The 3 questions presented a better result, with an AUC of 0.768 when associated with iron intake and 0.678 with serum ferritin level. Furthermore, the significance of their correlation coefficients were also preserved. The 3-question set showed an optimal threshold score of 4, presenting with sensitivity and specificity of 80.4% and 67% in predicting iron intake and 71.6% and 61% in predicting serum ferritin level. Summary of the diagnostic tests of the 3 questions and 5 questions may be found in Table 4 . Table 4 Summary of diagnostic tests performed in this study for the Modified NutricheQ Questionnaire.

Bogen’s questionnaire showed higher sensitivity of 91.5%, but lower specificity of 29%. Additionally, the questionnaire comprises of a higher number of questions (15 items). Overall, Bogen et al did not recommend the usage of their questionnaire to predict iron deficiency nor iron deficiency anemia. On the other hand, the questionnaire by Boutry et al had an overall higher diagnostic value, showing sensitivity, specificity, PPV and NPV of 71%, 79%, 22% and 97%. 18 However, it is worth noting that the questionnaire was primarily aimed for iron deficiency anemia (defined as hemoglobin of < 11g/dL and MCV < 73 fl). In our study, we aimed to look for a questionnaire capable of predicting iron deficiency before iron deficiency anemia occurs. Hence, we evaluated the Modified NutricheQ Questionnaire for its correlation with iron intake and serum ferritin level. Additionally, our 3-question Modified NutricheQ was evaluated on a population in which the ESR was ≤ 15 mm/hour. In real-life situations, ESR levels may not be readily available, hence its application in real life may pose a different diagnostic value. Addressing this concern, we also assessed the diagnostic values by including subjects with ESR ≥ 15 mm/hour. The AUC was 0.616 with sensitivity, specificity, PPV and NPV of 60.3%, 61.1%, 56.6% and 64.7%, respectively. Lastly, this study was conducted only in Central and East Jakarta due to financial and time limitations, representing only half of the Jakarta population. Hence, we recommend a similar study conducted on a bigger scale, allowing a better representation of the population. To the best of our knowledge, this study is the first to develop a non-invasive method in identifying iron deficiency risk factors in Indonesia. 5 Conclusion The Modified NutricheQ Questionnaire has good validity and reliability in identifying iron deficiency risk factors in the Indonesian population of age 1–3 years old, particularly the 3-question version. Threshold score of 4 provides sensitivity, specificity, PPV and NPV of 80.4%, 67%, 53.8% and 87.7% in predicting iron intake and 71.6%, 61%, 43.6% and 83% in predicting serum ferritin level, respectively. It is hoped that this simple and easy-to-use questionnaire will aid health care providers to screen iron deficiency risks in toddlers, allowing them to refer those at risks for confirmatory tests and therefore providing a more targeted and cost-efficient iron deficiency supplementation.

However, the questionnaire's reliability, measured by Cronbach\u0026rsquo;s alpha, was 0.208, lower than the study in Ireland, which reported 0.4.\u003csup\u003e\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e\u003c/sup\u003e Neither the modified nor the original NutricheQ Questionnaire achieved the desired reliability threshold of \u0026gt;\u0026thinsp;0.6. This discrepancy may be attributed due to the difference in the number of questions. The Modified NutricheQ Questionnaire comprises only 5 questions, while the NutricheQ Questionnaire has 18, allowing for a broader assessment beyond iron deficiency risk factors. Nevertheless, the Modified NutricheQ Questionnaire demonstrated a fair to perfect agreement in inter-rater reliability, with a Cohen\u0026rsquo;s kappa score of 0.4-1.\u003c/p\u003e \u003cp\u003eAmongst all questions in the Modified NutricheQ Questionnaire, only the question on growing-up milk showed statistical significance in its relationship with iron intake. This may be attributed to the question's design, which directly asks respondents for the daily volume in milliliters, potentially reducing recall bias. Even though the questions on liver and red meat consumption weren\u0026rsquo;t statistically significant, the question utilized a relatively more objective measurement unit compared to other questions. For instance, the questionnaire used a matchbox to describe the portion of red meat, aiding respondents in visualizing their intake accurately. However, red-meat based food, such as sausages, meatballs, and meatloaf, have various unstandardized portions, posing a limitation. Similarly, while eggs are easy to quantify, many mothers prepare eggs alongside other ingredients and often feed multiple children from the same plate at the same time. This may lead to inaccuracies in recalling the amount of egg consumed by a single toddler.\u003c/p\u003e \u003cp\u003eLikewise, only the question on growing-up milk has statistical significance in its relation to ferritin levels. However, relying solely on a single question about formula milk consumption to predict iron deficiency would not be able to accommodate children with dietary habits of consuming iron-rich foods without formula milk.\u003c/p\u003e \u003cp\u003eThe area under the ROC curve for the Modified NutricheQ associated with iron intake and serum ferritin are 0.709 and 0.598, respectively. Threshold score of 5 resulted in optimal sensitivity of 80.4% and optimal specificity of 48.3% when correlated to iron intake. On the other hand, when correlated to serum ferritin, optimal sensitivity and specificity were 73.1% and 43.4%. Ideally, a screening tool should have both sensitivity and specificity of at least 80%.\u003c/p\u003e \u003cp\u003eConsidering the consistent trend among 3 questions (formula milk intake, liver intake and red meat intake), we conducted a further analysis on the AUC of the 3 questions and compared it to the 5-question set. The 3 questions presented a better result, with an AUC of 0.768 when associated with iron intake and 0.678 with serum ferritin level. Furthermore, the significance of their correlation coefficients were also preserved. The 3-question set showed an optimal threshold score of 4, presenting with sensitivity and specificity of 80.4% and 67% in predicting iron intake and 71.6% and 61% in predicting serum ferritin level.

Bogen\u0026rsquo;s questionnaire showed higher sensitivity of 91.5%, but lower specificity of 29%. Additionally, the questionnaire comprises of a higher number of questions (15 items).

Receiver operating characteristic (ROC) analysis was performed to identify optimal threshold scores based on sensitivity, specificity, and area under the curve (AUC).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults\u003cbr\u003e\n \u003c/strong\u003eThe modified questionnaire demonstrated acceptable construct validity, with Spearman correlation coefficients \u0026gt;0.30 for all items except red meat intake. Inter-rater reliability ranged from fair to perfect agreement (Cohen’s kappa: 0.40–1.00). There was moderate correlation with dietary iron intake (r = 0.39, p \u0026lt; 0.01) and serum ferritin levels (r = 0.29, p \u0026lt; 0.01). The 5-question version had an optimal threshold score of 5, yielding a sensitivity of 80.4% and specificity of 48.3% in predicting iron intake; AUC was 0.709 (CI 95%: 0.648-0.770). A shortened 3-question version with a threshold of 4 maintained the same sensitivity (80.4%) and improved specificity (67.0%) for predicting iron intake (AUC = 0.768; 95% CI: 0.712–0.825), with sensitivity of 71.6% and specificity of 61.5% for predicting low serum ferritin (AUC = 0.682; 95% CI: 0.597–0.758).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion\u003cbr\u003e\n \u003c/strong\u003eThe modified NutricheQ Questionnaire demonstrated good validity and reliability for identifying risk factors of iron deficiency in Indonesian children aged 1–3 years. The shortened three-item version, in particular, shows promise as a non-invasive screening tool for use in low-resource settings.\u003c/p\u003e","manuscriptTitle":"Enhancing Treatment Precision: Evaluating The Validity and Reliability of Modified NutricheQ in Detecting Iron Deficiency in Children Aged 1-3 Years in Indonesia","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-05-27 17:53:41","doi":"10.21203/rs.3.rs-6566656/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"c4c3350d-202d-4d3d-ab2e-2103cb4d959e","owner":[],"postedDate":"May 27th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2025-06-26T13:53:57+00:00","versionOfRecord":[],"versionCreatedAt":"2025-05-27 17:53:41","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-6566656","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6566656","identity":"rs-6566656","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
