RESUMO

Background: Food fortification and micronutrient supplementation are public health strategies to improve micronutrient status in Guatemala; their population effectiveness has not been evaluated in recent years. Objective: We evaluated trends in food fortification, micronutrient supplementation, anemia, and iron deficiency among nonpregnant women aged 15-49 y [women of reproductive age (WRA)] and children 6-59 aged mo [preschool age children (PSC)]. Method: Nationally representative serial cross-sectional surveys were used to assess changes in hemoglobin, anemia, ferritin, iron deficiency, iron deficiency anemia, and self-reported consumption of fortifiable foods and micronutrient supplements during 2008/2009, 2013, 2015, 2016, 2017/2018, and 2018/2019. Predictors of hemoglobin and ferritin were assessed using generalized linear mixed models adjusted for survey year as random effects, and the consumption of fortifiable foods, supplements, and other potential confounders were fixed effects. Results: Multiple micronutrient powder consumption among PSC during the previous 3 mo was 53.3% (95% CI: 49.4, 57.2) in 2013 and 33.6% (28.8, 38.4) in 2018/2019. Anemia among PSC was 11.3% (8.0, 14.5) in 2008/2009 and 6.1% (3.6, 8.6) in 2018/2019. Anemia among WRA was 10.7% (7.2, 14.2) in 2008/2009 and 3.9% (2.7, 5.2) in 2018/2019. Iron deficiency among PSC was 15.5% (12.1, 19.0) in 2008/2009 and 10.9% (7.4, 14.5) in 2016 (lowest), but 17.1 (13.3, 21.0) in 2017/2018 (highest). Iron deficiency among WRA was 14.9% (11.6, 18.2) in 2008/2009, 13.8% (11.8, 15.8) in 2013 (lowest), and 18.9% (16.3, 21.6) in 2017/2018 (highest). Wheat flour/bread consumption was positively associated with hemoglobin among PSC, and sugar consumption was positively associated with hemoglobin among WRA. The reported consumption of fortifiable foods was not associated with ferritin among PSC or WRA. Conclusions: Guatemala has implemented multiple food fortification strategies, and anemia has declined. Increases in iron deficiency in 2017-2019 warrant further attention. Secular trends toward poverty alleviation, education, and development might be responsible for changes not explained by the micronutrient interventions evaluated.

RESUMO

Zinc is an essential micronutrient that promotes normal growth, development and immune function. In the context of persistent dietary zinc inadequacies, large-scale food fortification can help fill the gap between intake and requirements. Burkina Faso mandates wheat flour fortification with iron and folic acid. We used activity-based cost modelling to estimate the cost of adding zinc to the country's wheat flour fortification standard assuming (1) no change in compliance with the national standard, and (2) a substantial improvement in compliance. We used household food consumption data to model effective coverage, that is, the number of women of reproductive age (WRA) predicted to achieve adequate zinc density (zinc intake/1000 kcal) with the addition of fortification to diets. Without interventions, the prevalence of inadequate dietary zinc density was ~35.5%. With no change in compliance, the annual average incremental cost of adding zinc to fortified wheat flour was $10,347, which would effectively cover <1% of WRA at an incremental cost of ~$0.54/WRA effectively covered. Improving compliance added ~$300,000/year to the cost of the fortification programme without zinc; including zinc added another ~$78,000/year but only reduced inadequate intake among WRA by 3.6% at an incremental cost of ~$0.45/WRA effectively covered. Although the incremental cost of adding zinc to wheat flour is low ($0.01/wheat flour consumer/year), given low levels of wheat flour consumption, zinc fortification of wheat flour alone contributes marginally to, but will not fully close, the dietary zinc gap. Future research should explore potential contributions of zinc to a broader set of delivery vehicles.

RESUMO

Food fortification can be effective in reducing the prevalence of anemia and micronutrient deficiencies. This study assessed risk factors for-and the impact of the wheat flour program in Uzbekistan on-anemia, and iron and folate deficiency (FD) in non-pregnant women (NPW) of reproductive age. National data were analyzed for risk factors using multivariable regression. Additional iron intake from fortified flour was not associated with iron deficiency (ID) and did not result in a significantly different prevalence of anemia regardless of the levels, whereas women with additional folic acid intake had a lower relative risk (RR) of FD (RR: 0.67 [95% CI: 0.53, 0.85]). RR for anemia was greater in women with ID (RR: 4.7; 95% CI: 3.5, 6.5) and vitamin A insufficiency (VAI; RR 1.5; 95% CI: 1.3, 1.9). VAI (RR: 1.4 [95% CI: 1.3, 1.6]) and breastfeeding (RR: 1.1 [95% CI: 0.99, 1.2]) were associated with increased risk of ID, while being underweight reduced the risk (RR: 0.74 [95% CI: 0.58, 0.96]). Breastfeeding (RR: 1.2 [95% CI: 1.1, 1.4]) and inflammation (RR: 1.2 [95% CI: 1.0, 1.3]) increased risk of FD. FD results indicate that the fortification program had potential for impact, but requires higher coverage of adequately fortified wheat flour and a more bioavailable iron fortificant.

RESUMO

OBJECTIVE: To examine changes in the prevalence of anaemia and its correlates among children of pre-school age after implementation of wheat flour fortification with multiple micronutrients in Jordan. DESIGN: Retrospective analysis of the data from two repeated national cross-sectional panels of pre-school children. SETTING: The two surveys were conducted in 2007 and 2009, 16-20 months and 34-36 months, respectively, after implementation of wheat flour fortification with multiple micronutrients in Jordan. Anaemia was considered if Hb level was <11 g/dl. An anaemia prevalence of ≥40 % was considered a severe public health problem, while that of 20-39·9 % was considered a moderate public health problem. SUBJECTS: A total of 3789 and 3447 children aged 6-59 months tested in 2007 and 2009, respectively. RESULTS: The prevalence of anaemia in pre-school children declined from 40·4 % in 2007 to 33·9 % in 2009 (adjusted OR=0·74; P24 months (-13·7 points), children living in urban areas (-8·0 points), children from rich households (-9·0 points), children who had never been breast-fed (-17·0 points) and well-nourished children (-6·8 points). In both surveys, presence of childhood anaemia was strongly associated with child age ≤24 months, living in poor households, breast-feeding for ≥6 months, malnourishment, poor maternal education and maternal anaemia. CONCLUSIONS: The public health problem of childhood anaemia declined from severe in 2007 to moderate in 2009, after the implementation of wheat flour fortification with multiple micronutrients in Jordan.

RESUMO

Iron deficiency anemia (IDA) is a widespread nutritional disorder that affects a significant proportion of the Brazilian population. The obligatory fortification of wheat flour with iron and folic acid represents a strategy of the Brazilian Ministry of Health for combating IDA. However, several studies have reported the occurrence of iron in excessive concentrations and insufficient contents of folic acid in commercial flour samples. In the light of these information, a participatory observational study on the wheat flour production processes was undertaken in 11 major flour mills located in the São Paulo state, Brazil. This study aimed at writing a detailed good manufacturing practice (GMP) guidelines for the industrial sectors, including directives for standardized operational procedures (SOPs) on the flour fortification. The outcomes of this study are a GMP checklist and the recommended SOPs, which help to standardize the production processes in flour fortification, which currently is incongruous one, and also to facilitate the work of the government health inspectors...

RESUMO

O governo brasileiro adotou a fortificação de farinhas de trigo com ferro para auxiliar na redução da anemia no país. Esta intervenção não está administrada como um programa sanitário coordenado, com monitoramento de atividades e avaliação de impacto. Essas ações têm ocorrido na forma de pesquisa acadêmica dispersa no país, e têm focado na compreensão da estratégia pelos moinhos de trigo, no monitoramento da concentração de ferro nas farinhas do mercado, e na avaliação do impacto sobre a saúde de grupos vulneráveis à anemia. Os resultados dessas pesquisas levam a pensar num trabalho coordenado, com avaliações padronizadas sobre alvos adequados, e na necessidade de instrumentos específicos de monitoramento da fortificação para a indústria e para a fiscalização sanitária. O objetivo deste trabalho foi elaborar um roteiro de verificação das Boas Práticas de Fabricação de farinhas enriquecidas com ferro em moinhos de trigo, que incluísse diretrizes para procedimentos operacionais padronizados de fortificação, nas hipóteses da existência de grande diversidade tecnológica de fortificação nos moinhos, e na necessidade deste checklist pela fiscalização para auditar esse processo. A padronização desses procedimentos é imprescindível para a efetividade do combate a anemia, porque normaliza a qualidade dos produtos fortificados, tornando-os mais homogêneos. Para elaborar o roteiro de verificação foi realizada uma pesquisa bibliográfica científica e de regulação, sobre Boas Práticas de Fabricação. Um roteiro inicial, para uma pesquisa de observação da indústria do trigo, foi extraído das legislações da vigilância sanitária, inclusive do programa nacional de fortificação do sal com iodo. A partir desse roteiro, entre 2007 e 2008, o pesquisador realizou uma pesquisa etnográfica em 11 moinhos de trigo no estado de São Paulo e elaborou uma lista de verificação de procedimentos operacionais de fortificação, contando com a colaboração de 20 profissionais de vigilância sanitária, convidados para aplicar o roteiro de BPF e apresentar parecer sobre o instrumento elaborado. Eles receberam do pesquisador uma capacitação em tecnologia de produção de farinhas em moinhos de trigo e posteriormente, colaboraram na elaboração e avaliação da efetividade do instrumento, acompanhando o pesquisador nas observações dos moinhos. O resultado é uma extensa lista de verificação das Boas Práticas de Fabricação em moinhos de trigo, com atenção às operações de fortificação das farinhas, que incluem procedimentos de dosagem e homogeneização de micronutrientes altamente diluídos na farinha, e de controles de qualidade de formulações de fortificantes e produtos finais, inclusive o registro de todas as informações. No checklist são indicados procedimentos operacionais padronizados de fortificação de farinhas e também, a amostragem para análise laboratorial da concentração de ferro e ácido fólico baseado no volume de moagem de trigo diário do moinho. A lista de verificação incluiu observações de moinhos de grande porte, que utilizavam diferentes sistemas de dosagem (volumétricos e gravimétricos) dos compostos de micronutrientes, controlados por procedimentos desde mecânicos até eletrônicos. Observações de laudos analíticos de farinhas levaram a concluir que existe ampla faixa de variação na concentração de micronutrientes entre as amostras analisadas. A qualidade dos resultados pode ser atribuída à baixa freqüência de controle dos sistemas de dosagem de menor automação, ao ponto de dosagem dos fortificantes que provoca pouca homogeneização da farinha fortificada, e à qualidade do composto de micronutrientes. Para melhorar a confiabilidade dos resultados de análise de ferro e ácido fólico são indicados procedimentos padronizados para análises laboratoriais com métodos analíticos validados. Concluiu-se que o método de observação participativa dos moinhos catalisou o conhecimento do pesquisador sobre a cultura do setor moageiro do trigo, fornecendo uma coleção significativa de itens de observação, que influenciam a qualidade dos procedimentos de fortificação. O checklist resultante de Boas Práticas de Fabricação enfocado na fortificação de farinhas contempla a variedade de situações tecnológicas observadas no mercado do estado de São Paulo e sugere-se sua utilização pelos moinhos de trigo para monitorar a produção de farinhas fortificadas e pela vigilância sanitária para auditorias e inspeções dos procedimentos industriais de fortificação.


The Brazilian government adopted the compulsory fortification of wheat flour with iron and folic acid to help reduce the iron deficiency anemia in the country. This intervention is not managed as a centralized sanitary program, with specific activities to monitor and to evaluate the impact on the health of a target population. These actions are being performed as a country spread academic research, on: the understanding of the intervention by wheat mills managers; the monitoring of the iron and folic acid concentration on samples of wheat flour for bakery and domestic use; and the evaluation of the intervention impact on the health of anemia vulnerable groups. The results of these researches make us think about a coordinated work, with standardized evaluations on adjusted targets, and specific instruments for monitoring the fortification process in the mills, and to be adopted by the sanitary inspection. The objective of this dissertation is to draw up a checklist for the inspection of the Good Manufacturing Practices of wheat mills focused in the production of iron fortified flour, including directions for the standardization of the fortification processes, in case there is great technological diversity in the mills in the country. In addition, it is useful to provide public health agents with a checklist for sanitary inspection. The standardization of the fortification processes is essential for the effectiveness of the fight against anemia, because it brings the quality of the fortified products into line, thus making them more homogeneous. To draw up the checklist, a scientific and regulatory bibliographical research was conducted on Good Manufacturing Practices. An initial checklist to make the first observation of the wheat mills was obtained from the Sanitary Surveillance Agency legislation, including the national program for fortifying salt with iodine. Between 2007 and 2008, the researcher conducted an ethnographic research in 11 wheat mills in the state of São Paulo, using the initial guideline, and elaborated the checklist for the inspection of the flour fortification operational procedures, counting on the contribution of 20 professionals of the Sanitary Surveillance system, who were invited both to use the checklist and to give their expert remarks. The researcher shared his knowledge and trained these professionals on wheat flour technology, and after that they could better collaborate to test the effectiveness of the checklist, accompanying the researcher during the wheat mills observation trip. The result is a comprehensive checklist for Good Manufacturing Practices in wheat mills, with special focus on the operations to fortify flour, including dosage and dilution of micronutrients, and quality control of micronutrients and fortified flours, including the registration of all information. The checklist highlights the standardized operational procedures for flour fortification and the sampling for laboratory analysis of iron and folic acid contents, based on the daily grinding volume of wheat in the mill. The checklist includes observation of big mills that used different systems for dosaging micronutrients (volumetric and gravimetrical), controlled by mechanic and electronic procedures. The analysis of some analytical reports on flours showed a considerable variation in the concentration of micronutrients of the samples. These results can be attributed to the infrequent control of the dosage systems of micronutrients; the point of dosage of fortifiers in the production line, thus impairing homogenization of the flour; and to the quality of the micronutrient compounds. To improve the reliability of lab results for iron and folic acid, some standardized procedures with validated analytical methods are recommended. As a conclusion, the ethnographic research method of participant observation of wheat mills has accelerated the researcher´s knowledge of the culture of the wheat milling sector. This approach brought significant information on items to be observed that influence the quality of the fortification process. The Good Manufacturing Practices checklist focused on the fortification of flour included a variety of technological situations observed in the state of São Paulo. We suggest its use for monitoring the production of fortified flours by the mills, and for inspections of the fortification procedures by the Sanitary Surveillance system.

RESUMO

Anemia caused by iron defi ciency is very prevalent in Brazil, and so the government decided that wheat flour should be fortified with iron. This paper presents the perceptions of the wheat milling industry on the Brazilianlaw which determines flour fortification. Professionals responsible for implementing the law, and representing 60% of the Brazilian wheat flourmarket, were interviewed and the answers analyzed using the method of Collective Discourse of the Subjects. This method combines the main ideas of the subjects, using their own verbal expressions, to reveal their perceptions. Interpretation of the results showed that millers agree with the law; how everthey complained about the authoritarian way in which it was introduced. They had previously asked the government for advertising to educate the consumers, but this was not done. The millers do not believe that the population of low socioeconomic status will be benefitted by this law because of the high cost of wheat-derived products. The millers say they are observing the law, in spite of initial technological deficiencies. These have been solvedby using the services of micronutrient suppliers and over-dosing the flour.Wheat flour for domestic use is usually fortified with reduced iron, but other iron compounds are used in the flour supplied to industry. In the perceptionof the millers, the fortification issues are more administrative and politicalthan technical.


Debido a la elevada prevalencia en el paísde anemia por défi cit de hierro, el gobiernobrasileño decidió implantar la fortificaciónde la harina de trigo con este elemento. Estetrabajo expone la opinión de la industriamolinera sobre la resolución que determinala fortificación. Fueron entrevistados los profesionales responsables por la implementación de la medida que su ministran 60% de laharina al mercado brasileño. Las respuestas seanalizaron utilizando el método del Discursodel Sujeto Colectivo. Este método combina las principales ideas de los entrevistados pararevelar sus opiniones sobre el tema. El análisis de los resultados mostró que los molinerosestán de acuerdo con la legislación, pero no concuerdan con la forma autoritaria como fue presentada. Ellos habían solicitado al gobiernola realización de propaganda educativa delos consumidores, que no fue realizada. La industria no cree que la población de bajo poder adquisitivo será beneficiada por la medida, debido al elevado costo de los derivados detrigo. Afirman estar cumpliendo la legislación, a pesar de las dificultades tecnológicas, que hansido resueltas con sobredosis de micronutrientesen las harinas. La harina de trigo para uso doméstico es generalmente fortificada con hierroreducido, pero otros compuestos de hierro son usados para la harina industrial. El juicioque la industria tiene es que los problemas defortificación son más políticos y administrativosque técnicos.

Este trabalho apresenta a percepção da indústria moageira do trigo sobre a Resolução brasileira que determina a fortificação.Profissionais responsáveis pela implementação da legislação e que fornecem 60% da farinha do mercado brasileiro foram entrevistados e suas respostas foram analisadas usando o métododo Discurso do Sujeito Coletivo. Este combina as principais idéias dos entrevistados, usando suas expressões verbais para revelar suas percepções sobre o assunto. A interpretação dos resultados mostrou que os moleiros concordam com a legislação, no entanto reclamam sobre a forma autoritária como esta foi apresentada. Eles haviam solicitado ao governo que realizas se propaganda para educar os consumidores, mas isto não foi feito. A indústria não acredita que as populações de baixo poder aquisitivo serão atendidas pela legislação, devido ao alto custo dos produtos derivados do trigo. Eles afirmam estar cumprindo a legislação, apesar das dificuldades tecnológicas, que têm sido resolvidas com a sobre-dosagem na farinha dos micronutrientes, cujos fornecedores incluem serviços laboratoriais. A farinha de trigo para uso doméstico é geralmente fortificada com ferroreduzido, mas outros compostos de ferro são usados para a farinha industrial. Na percepção da indústria, os problemas da fortificação são mais político-administrativos que técnicos.
