Introdução: O baixo peso ao nascer (BPN) representa risco crucial para as crianças. Em contrapartida, a amamentação é considerada a estratégia de maior impacto na redução da mortalidade em crianças menores de cinco anos. O aleitamento materno exclusivo (AME) é recomendado até o sexto mês de vida, devendo ser complementado até dois anos de idade ou mais. Crianças com consumo alimentar inadequado desde a infância tendem ao desenvolvimento precoce de sobrepeso e obesidade, além de outras doenças crônicas associadas. Objetivo: Verificar o padrão de aleitamento materno (AM) e as práticas de alimentação complementar de lactentes menores de um ano nascidos com baixo peso e analisar a influência de determinantes individuais e contextuais. Métodos: Estudo transversal com dados de 64 municípios brasileiros (incluindo as capitais e Distrito Federal) que abrangeu 5115 lactentes menores de um ano com BPN da Pesquisa de Prevalência de Aleitamento Materno (PPAM) em Municípios Brasileiros, 2008. O questionário continha questões sobre a prática de AM e sobre o consumo de todos os grupos alimentares nas últimas 24 horas. A tese gerou três manuscritos: 1) Descreve as práticas de aleitamento materno, o consumo de líquidos e alimentos semi-sólidos nas últimas 24 horas e os indicadores de consumo alimentar de lactentes entre seis e 11,9 meses segundo estratos de BPN. 2) Avalia os determinantes individuais e contextuais do AME. 3) Analisa a influência de determinantes individuais e contextual sobre a dieta diversificada e sobre o consumo de alimentos ultraprocessados em lactentes de seis a 11,9 meses com BPN. Nos manuscritos 2 e 3, os determinantes individuais corresponderam às características socioeconômicas (representadas pela proxy escolaridade materna), dos lactentes (idade; sexo), maternas (faixa etária; situação de trabalho; paridade) e aos serviços de saúde (local de acompanhamento ambulatorial). No manuscrito 2 foi incluído também o \'nascimento em Hospital Amigo da Criança (HAC)\'. Os determinantes contextuais corresponderam às características dos municípios, representadas pelas variáveis \'número de Bancos de Leite Humano (BLH) por mil nascidos vivos\' e \'Índice de Desenvolvimento Humano do município\' no manuscrito 2, e \'prevalência estimada de desnutrição infantil\' como proxy de pobreza, no manuscrito 3. Para análise, utilizou-se regressão de Poisson com estrutura multinível e adotou-se nível de significância de 5%. Resultados: Descritos de acordo com cada manuscrito produzido: 1) No estrato de muito BPN o AME até 60 dias e 90 dias foi mais elevado do que nos demais, mas com intervalos de confiança superpostos. A prevalência de AME em menores de seis meses apresentou patamar semelhante nos três estratos de peso ao nascer. A prevalência de AM na primeira hora de vida e o AM foram mais prevalentes entre os nascidos com 2000 a 2499g. Observou-se consumo elevado de alimentos ultraprocessados (AUP) em lactentes de 6|-9 e de 9|-12 meses, sendo esta prevalência maior quanto maior o PN. As prevalências dos indicadores de consumo alimentar estão aquém do recomendado. 2) O AME foi mais prevalente entre lactentes cujas mães tinham de 20 a 35 anos (RP=1,35; IC95%=1,09-1,69), não trabalhavam fora (RP=1,36; IC95%=1,08-1,71) ou estavam em licença maternidade(RP=1,30; IC95%=1,06-1,59); lactentes que nasceram em HAC (RP=1,22; IC95%=1,09-1,37) e que residiam em municípios com maior número de BLH por mil nascidos vivos (RP=1,42; IC95%=1,14-1,76). 3) Aproximadamente 59% dos lactentes consumiram alimentos ultraprocessados, enquanto 29% apresentaram dieta diversificada. Crianças cujas mães residiam em municípios com prevalência de desnutrição infantil inferior a 10% (RP=1,66; IC95%=1,23-2,24), tinham escolaridade superior (RP=1,37; IC95%=1,18-1,60) e trabalhavam fora de casa (RP=1,29; IC95%=1,12-1,49) foram mais propensas a oferecer uma alimentação diversificada. O consumo de alimentos ultraprocessados foi maior entre lactentes cujas mães residiam em municípios com prevalência de desnutrição infantil inferior a 10% (RP=1,17; IC95%=1,04-1,31), eram mais jovens (RP=1,30; IC95%=1,15-1,46) e multíparas (RP=1,16; IC95%=1,03-1,30). Conclusões: A tese evidenciou o efeito independente de estratégias que integram a Política Nacional de Aleitamento Materno. Nascer em HAC, residir em município com maior disponibilidade de BLH e o direito à licença maternidade remunerada exercem influência positiva sobre a prática de AME. Este resultado aponta para a necessidade de expansão da cobertura dessas estratégias com vistas ao cumprimento das metas de AM propostas pela OMS. Foi detectado impacto de fatores individuais e contextuais sobre a qualidade da dieta que demandam o desenvolvimento de estratégias eficazes para aumentar o consumo de alimentos in natura ou minimamente processados e diminuir o consumo de ultraprocessados nesta população vulnerável. / Introduction: Low birth weight (LBW) represents a major risk to children. On the other hand, breastfeeding is recognized as the strategy with the greatest impact on reducing childhood mortality. Thus, exclusive breastfeeding (EBF) is recommended up to the sixth month of the child\'s life and should be complemented up to two years of age or more. Inadequate nutrition during early childhood is associated with early development of overweight, obesity, and other chronic diseases. Objectives: 1) To verify the breastfeeding pattern and complementary feeding practices of infants under one year of age who were born with low weight and, 2) to assess the influence of its individual and contextual determinants. Methods: This cross-sectional analysis included 5,115 infants less than one year of age born with LBW from the Second National Survey of Breastfeeding Prevalence (IIPPAM). The survey evaluated the situation of breastfeeding and complementary feeding in 64 Brazilian municipalities (including capitals and the Federal District). Dietary data was collected using a questionnaire with dichotomous questions about breastfeeding practices and consumption of foods from all food groups in the previous 24 hours. The thesis generated three manuscripts as follows: 1) The first one describes breastfeeding practices, consumption of any liquids (including non-human milk) and semi-solid foods in the last 24 hours, and indicators of young child feeding practices of infants between six and 11.9 months according to birth weight strata. 2) The second manuscript evaluates individual and contextual determinants of exclusive breastfeeding. 3) The third one assesses the influence of individual and contextual factors on dietary diversity and on consumption of ultraprocessed foods in LBW infants between six and 11.9 months of age. The individual-level-factors studied on manuscripts 2 and 3 were: socioeconomic (represented by the proxy maternal education), infants (age, sex), maternal (age range, work situation, parity), and health services (type of outpatient follow-up). The individual-level-factor \'being born in a Baby-Friendly Hospital (BFH)\' was also studied on manuscript 2. The community-level factors studied at the second level in the manuscript 2 included municipalities\' characteristics (number of Human Milk Banks (HMB) per thousand live births in each municipality in 2007, and Human Development Index of the municipality, used as proxy of poverty). The community-level factor studied at the second level in manuscript 3 was municipal prevalence of childhood malnutrition, used as a proxy for poverty. The individualized effect of the study factors on the outcome was evaluated using multilevel Poisson regression analysis. For all manuscripts, a significance level of 5% was adopted. Results: Summary of the findings of each manuscript produced: 1) In the stratum of very LBW, the rates EBF up to 60 and 90 days were higher among very LBW infants compared to others, however with overlapping confidence intervals. The overall prevalence of breastfeeding in infants under six months was similar among the groups. The rates of breastfeeding in the first hour of life and total breastfeeding were both higher among those born with weight between 2000 and 2499g. A high consumption of ultraprocessed foods was observed among infants aged 6|-9 and 9|-12 months, and it was noted that the higher the birth weight the higher was the prevalence of consumption. The prevalence of food groups consumption indicators are below the recommended. 2) EBF was more prevalent among infants born with LBW whose mothers were 20-35 years old, those who did not work outside the home or were on paid maternity leave; those born in a BFH; and those who lived in municipalities with the highest number of HMB per thousand live births. 3) Approximately 59% of infants consumed ultraprocessed foods, while 29% achieved dietary diversity. Mothers with the highest education level, those who worked outside the home, and who lived in municipalities with a prevalence of child malnutrition below 10% were more likely to offer a diverse diet. Consumption of ultra-processed foods was higher among infants whose mothers were younger, multiparous, and who lived in municipalities with a prevalence of child malnutrition below 10%. Conclusions: The thesis augments the evidence that integrated actions of the National Breastfeeding Program already implemented in Brazil - BFH Initiative, Brazilian Network of HMB, and adoption of labor laws for paid maternity leave - are associated with EBF even in the vulnerable population of infants born with LBW. Our results also suggest the need to expand and intensify the coverage of these strategies in order to meet the goals of breastfeeding proposed by the World Health Organization. Our findings also indicate the effects of individual and community-level factors on the dietary quality of this population, suggesting a need for developing effective strategies to increase consumption of unprocessed or minimally processed foods, while decreasing the ultra-processed counterpart for this vulnerable population.

Thesis (MNutr (Interdisciplinary Health Sciences. Human Nutrition))--Stellenbosch University, 2008. / Objective: Primary: To investigate the effect of pasteurisation on the composition of expressed breast milk from HIV positive mothers and its adequacy in relation to the growth of their VLBW premature infants. Methods: A descriptive, prospective case-controlled pilot study was performed in 3 regional state hospitals in the Western Cape, South Africa. The control and study groups consisted of 12 HIV negative and 11 HIV positive mothers, with their VLBW premature infants, respectively. All mothers (19 - 35 years old) belonged to the Xhosa ethnic group. All infants were born <34 weeks gestation and birth weight <1500g. Eight breast milk samples were collected on days 6, 7, 13, 14, 20, 21, 27 and 28 from all mothers during the first 28 days after birth. Breast milk was expressed by hand or pump from either the right or left breast. Half of each breast milk sample was kept raw. The remaining sample was Pretoria pasteurised, after which both samples were subdivided into 3 or 4 aliquots to determine energy, protein, carbohydrate, fat, folate, calcium, phosphorus, magnesium, sodium, otassium, iron, copper, zinc content and HI viral load (study group only). The mothers’ dietary intake during pregnancy and lactation was obtained by means of a quantitative food frequency questionnaire and repeated 24-hour recall respectively. The infants’ dietary intake was recorded daily. Mothers’ anthropometric measurements taken at study entry and exit were weight, height and mid-upper arm circumference. All infants’ daily weight, as well as length and head circumference at birth and on day 28 postpartum was obtained. Biochemical analysis was performed on the blood samples obtained at study entry and exit from all mothers and infants. For statistical analysis, Statistica® (release no 7, 2006) was used for repeated measures analysis of variance (ANOVA) to determine the effect of HIV, pasteurisation, milk expression and time on the composition of the breast milk. Results: There was no significant difference in the studied macro- and micronutrient composition between raw or pasteurised expressed breast milk from HIV positive and HIV negative mothers with premature infants. A significant decline in breast milk protein (p<0.01), magnesium (p=0.045), potassium (p=0.002), zinc (p<0.01) and copper (p=0.03) content was observed for the whole study population over time, while folic acid content increased significantly (p=0.012) over time. The sodium/potassium ratio of both groups remained strongly indicative of the presence of sub-clinical mastitis. A significant (p=0.03) greater mean volume of milk was obtained with pump [42.5 Standard Deviation (SD) 18.1 ml], compared to hand expression [36.7 (16.7) ml]. Method of expression did not result in a significant difference in breast milk composition for any of the nutrients studied. Eight (35%) infants were born SGA while 21 (91%) infants were SGA on day 28. The infants gained a mean of 16.37 (4.5) g/kg/day (i.e. 91% of the recommended growth rate of >18g/kg/day) from the day on which birth weight was regained. The control and study group infants respectively consumed a mean of 3.27 (1.36) and 3.21 (1.36) g protein/kg/day and 138.1 (33.8) and 142.3 (33.8) kcal total energy/kg/day. This corresponds to a PER of 2.6 (control group) and 2.5 (study group) respectively, which cannot provide for the increased growth needs of the SGA infant in need of catch-up growth. Six infants experienced an incident of Grade 1 NEC which resolved and all completed the study. Two (18%) HIV-exposed infants were found to be HIV positive at 28 days post delivery. Four participating infants died. No adverse event or mortality was related to the study protocol as no intervention was undertaken. Conclusion: HIV positive Xhosa mothers provide as nutritious breast milk to their VLBW premature infants as HIV negative Xhosa mothers. Maternal nutrient intake during pregnancy and lactation did not have a significant effect on the nutritional composition of breast milk, except for folate content.

The WHO Code of Marketing of Breast Milk Substitute is a public health recommendation to reduce preventable causes of infant morbidity and mortality associated with malnutrition. Irresponsible marketing of infant formula in hospitals is a threat to exclusive breastfeeding. Nurses are mandated to support, encourage and protect breastfeeding and to familiarize themselves with their responsibilities under this Code. The researcher explored Geneva nurses' knowledge of the Code and its impact in practice. Eighty seven point seven percent of the participating nurses had poor level of knowledge of the Code. Poor knowledge of the Code impacts on the quality and consistency of information given to mothers in hospitals. Inadvertent violations of the Code were observed among a minority of the respondents: 7.3% indicated that they received gifts; 2.4% received sponsorships to conferences. Training about the Code and its application in counseling is recommended to complement the babyfriendly initiative at hospitals to improve nutrition outcomes. / Health Studies / M.A. (Public Health)

Introdução - A anemia ferropriva constitui um problema de saúde pública da maior relevância dadas a elevada frequência com que ocorre e as consequências dela decorrentes. Programas de intervenção foram implantados para seu controle: a fortificação universal de farinhas de trigo e milho com ferro e a suplementação profilática com sulfato ferroso (PNSF), especialmente para lactentes. Ao mesmo tempo, houve a aproximação dos serviços públicos de saúde da população com a transformação de Unidades Básicas de Saúde em Estratégia da Saúde da Família em todo o território nacional. Objetivos - Estimar as prevalências de anemia na criança no primeiro ano de vida e na mãe biológica e a relação entre elas; identificar a prática alimentar familiar e da criança. Metodologia - Estudo transversal desenvolvido em UBS no universo de crianças no primeiro ano de vida e suas mães (122 pares), que compareceram às oito UBSs que mantêm uma rotina de puericultura. Os dados antropométricos, socioeconômicos, de consumo alimentar foram obtidos através de entrevista e informações de prontuários. O sangue para diagnóstico de anemia foi colhido por punção digital e leitura em hemoglobinômetro portátil. Resultados - A prevalência de anemia entre as mulheres ([Hb]<12,0g/dL) foi de 61,5 por cento e entre as crianças encontrou-se 77,0 por cento delas com [Hb]<11,0g/dL, sendo que 30 das 34 crianças com até quatro meses de idade estavam nessa condição. Entre as mais velhas, a prevalência de [Hb]<11,0g/dL foi de 72,7 por cento . Foi verificado através do teste de Mc Nemar e do coeficiente de correlação de Yule que a prevalência de anemia em mães e seus filhos são significativamente diferentes e não existe correlação entre elas. Das oito unidades de serviços de saúde, seis são Estratégia de Saúde da Família; no entanto, apenas 10 por cento das mulheres referiram ter participado de alguma atividade de educação alimentar. Durante a gestação, 106 mulheres referiram a ingestão de sulfato ferroso e 44 delas referiram seu uso no puerpério. Entre as 54 crianças com 6 a 11 meses de idade, 21 estavam ingerindo o suplemento. A alimentação familiar tem por base o arroz/feijão e carnes diariamente nas refeições. Dentre os alimentos fortificados com ferro, o pão foi referido como alimento diário e o macarrão como alimento de consumo semanal. Frutas, verduras e legumes apareceram com frequência abaixo do recomendado. Dentre as 34 crianças menores de quatro meses, apenas 38 por cento mantinham-se em regime de aleitamento materno exclusivo. Entre as 88 mais velhas, 55 por cento ainda ingerem o produto junto com a alimentação complementar. Alimentos fontes de ferro não são frequentes na alimentação dos lactentes cuja restrição à diversidade alimentar é nítida. Legumes, frutas e verduras foram referidos com pouca frequência, estando ausentes na maioria dos questionários. Conclusões - Verificou-se alta prevalência de anemia na população estudada e que não existe correlação entre as prevalências de anemia nas mães e respectivas crianças. Constatou-se também que, embora alimentos fontes de ferro estejam presentes na alimentação habitual da família e suplementos profiláticos de ferro estejam disponíveis para a população atendida pelos serviços públicos de saúde de Santa Isabel, a deficiência marcial ocorre em grande proporção, sugerindo a necessidade de que os profissionais das UBSs sensibilizem a população através de orientação nutricional destinada à família como um todo / Introduction - Deficiency anemia is a public health problem of great importance given the high frequency with which it occurs and the consequences resulting there from. Intervention programs were implemented for its control: universal fortification of wheat flour and corn prophylactic supplementation with iron and ferrous sulfate (PNSF), especially for infants. At the same time, there was the approach of public health services of the population with the transformation of Basic Health Units in the Family Health Strategy across the country. Objectives - To estimate the prevalence of anemia in children in the first year of life and the biological mother and the relationship between them; identify feeding practices family and child. Methodology - Sectional study developed in UBS in the universe of children in the first year of life and their mothers (122 pairs), who attended 8 UBS maintains a routine childcare. Anthropometric, socioeconomic, dietary intakes were obtained through interviews and information from medical records. Blood samples for diagnosis of anemia were collected by fingerstick reading and portable hemoglobin. Results - The prevalence of anemia among women ([Hb] <12.0 g / dL) was 61.5 per cent among children and found them to be 77.0 per cent ([Hb] <11.0 g/dL) with 30 of the 34 children up to four months of age were in this condition. Among older women, the prevalence of [Hb] <11.0 g / dL was 72.7 per cent . It was determined using the McNemar test and the correlation coefficient of Yule that the prevalence of anemia in mothers and their children are significantly different and there is no correlation between them. 8 units of health services are 6 Family Health Strategy however, only 10 per cent of women reported having participated in some educational activity feed. During pregnancy 106 women referred to the ingestion of ferrous sulfate and 44 of them reported their use postpartum. Among the 54 infants 6-11 months of age, 21 were ingesting the supplement. The family diet is based on rice/beans and meats, in daily meals. Among the iron-fortified foods such as bread was the daily food and noodles as food consumption weekly. Fruits and vegetables appeared frequently below recommended. Among the 34 children under 4 months only 38 per cent had remained regime of exclusive breastfeeding. Among the 88 older, 55 per cent still ingest the product along with complementary feeding. Food sources of iron are not frequent in the feeding of infants whose restriction on food diversity is clear. Vegetables, fruits and vegetables have been reported infrequently are absent in most questionnaires. Conclusions - There was a high prevalence of anemia in this population and that there is no correlation between the prevalence of anemia in mothers and their children. It was also found that although food sources of iron are present in normal feed the family, and prophylactic iron supplements are available to the population served by the public health services of Santa Isabel, martial deficiency occurs in large proportion suggesting the need for professionals of UBS sensitize the population through nutritional guidance designed the family as a whole

The objectives of this study were: a) to observe the diet of premature and full-term babies aged under two years, assessing the breastfeeding indicators of the World Health Organization (WHO): exclusive breastfeeding, predominant breastfeeding, complementary proper foods, continued breastfeeding and milk bottle feeding; b) to compare standardized diets among premature and full-term newborns. Casuistics: Two hundred of mothers of newborns and infants participated the study. They were divided into four groups (50 each): Group I (< 4 months); Group II ( between 6 and <10 months); Group III ( between 12 and < 16 months); Group IV ( between 20 and <24 months). Method: At first the project was approved by the Ethics Committee of Research. Afterwards, before the routinely consulting, the mothers answered a questionnaire based on a methodology standardized by WHO about information of diet during the last 24 hours. Results: The majority of mothers was adult (lesser than 20% of adolescents), able to read and write (97%; IC:93 to 99%), living with a partner (estimative of 79.5%; IC:73 to 85%), minority worked outside (27%; IC:21 to 34%). Average of 70.5% (IC:64 to 77%) of cesarean labor and 50.5% (IC:43 to 57%) of premature labor. The minority performed the first breastfeeding in the labor room (estimative of 18%; IC:13 to 25%). In Group I, the rate of exclusive breastfeeding was 40% (IC:26 to 55%), and predominant breastfeeding 28% (IC:16 to 42%). In Group II, the rate of breastfeeding with complementary proper foods was 46% (IC:32 to 61%). In Group III, the rate of continued breastfeeding up to one year was 30% (IC:18 to 45%); and in Group IV, the rate of continued breastfeeding up to two years was 32% (IC:20 to 47%). The rate of milk bottle feeding for babies under one year was 57% (IC:47 to 67%). Conclusions: The characteristics of the groups of mothers and babies were almost homogeneous, both have been following partially the facilitator routines of breastfeeding. As the age of babies increased, breastfeeding diminished, with the early introduction of liquids and complementary diet. The standardized diet of full-term and premature babies was similar. / O Brasil adota uma política de saúde voltada para a promoção, proteção e apoio ao aleitamento materno, como forma de reduzir a mortalidade infantil e melhorar a qualidade de vida das crianças. Os objetivos deste estudo foram; a) caracterizar a amostra e verificar a alimentação de bebês com idade inferior a dois anos, prematuros e a termo, avaliando os indicadores de aleitamento materno propostos pela Organização Mundial de Saúde (OMS): amamentação exclusiva, amamentação predominante, alimentação complementar oportuna, amamentação continuada e alimentação por mamadeira; b) comparar padrões alimentares entre bebês prematuros e a termo. Casuística: participaram do estudo 200 mães de recém-nascidos e lactentes divididas em quatro grupos de 50 mães; Grupo 1 (<4 meses); Grupo II (entre 6 e <10 meses); Grupo III (entre 12 e <16 meses); Grupo IV (entre 20 e <24 meses). Método; O projeto foi aprovado pelo Comitê de Ética em Pesquisa. Antes da consulta rotineira, as mães responderam a um questionário, fundamentado em metodologia padronizada pela OMS, sobre informações alimentares relativas as últimas 24 horas. Resultados: A maioria das mães encontrava-se na fase adulta (menos de 20% de adolescentes), alfabetizadas (97%; lC:93 a 99%), com parceiros (estimativa de 79,5%; 10:73 a 85%), minoria trabalhava fora (27%; 10:21 a 34%). Estimativa de 70,5% (lC:64 a 77%) de parto cesárea e 50,5% (lC:43 a 57%) de prematuridade. A minoria realizou a primeira mamada na sala de parto (estimativa de 18%; lC:13 a 25%). No Grupo 1 a taxa de aleitamento materno exclusivo foi 40% (lC:26 a 55%) e de aleitamento materno predominante 28% (10:16 a 42%). No Grupo II a taxa de aleitamento materno com alimentação complementar oportuna de 46% (10:32 a 61%). Para o Grupo III, a taxa de aleitamento materno continuado até um ano foi de 30% (10:18 a 45%) e para o Grupo IV a taxa de aleitamento materno continuado até dois anos foi de 32% (10:20 a 47%). Nota de Resumo A taxa de alimentação por mamadeira para menores de um ano foi de 57% (10:47 a 67%). Conclusões: As características dos grupos de mães e crianças foram quase homogêneas; ambos seguiam parcialmente rotinas facilitadoras da amamentação. O aleitamento materno diminui com o aumento da idade, havendo a introdução precoce de líquidos e alimentação complementar. O padrão alimentar dos bebês a termo e prematuros foi semelhante.
