Median Duration Of Exclusive Breastfeeding Research Articles

Factors associated with exclusive breastfeeding practices among mothers in Goba district, south east Ethiopia: a cross-sectional study

BackgroundExclusive breastfeeding is defined as feeding infants only breast milk, be it directly from breast or expressed, with no addition of any liquid or solids apart from drops or syrups consisting of vitamins, mineral supplements or medicine, and nothing else. Several studies have shown that exclusive breastfeeding for the first six months plays a great role in preventing morbidity and mortality. However, in Ethiopia a large portion of infants are not exclusively breastfed according to the infant feeding recommendations. Understanding the factors that influence exclusive breastfeeding is crucial to promoting the practice. This study was carried out to identify factors predicting exclusive breastfeeding among mothers in Bale Goba district, south east Ethiopia.MethodsA community-based cross-sectional study was conducted from March to February 2010 involving both quantitative and qualitative data. A total of 608 mothers were selected randomly. A convenience sampling technique was used to generate the qualitative data. The qualitative data were analyzed using thematic frameworks. A multivariable logistic regression analysis was used to identify independent predictors of exclusive breastfeeding after controlling for background variables.ResultsThe prevalence of exclusive breastfeeding in the last 24 hours preceding the survey was 71.3%. The median duration of exclusive breastfeeding was three months and mean frequency of breastfeeding was six times per day. Being unemployed [AOR: 10.4 (95% CI: 1.51, 71.50)] and age of infants of less than two months [AOR: 5.6 (95% CI: 2.28, 13.60)] were independently associated with exclusive breastfeeding.ConclusionsA large proportion of infants are not exclusively breastfed during the first 6 months, despite what is recommended in the national and global infant and young child feeding (IYCF) guidelines. Employed mothers were less likely to practice exclusive breastfeeding, implying the need for promoting workplace breastfeeding practices and creating an enabling environment for exclusive breastfeeding. Extensions of maternity leave up to the first six month of child’s age to achieve optimal level of exclusive breastfeeding practices should also be looked into as an alternative solution.

Fatores associados à interrupção precoce do aleitamento materno: um estudo de coorte de nascimento em dois municípios do Recôncavo da Bahia, Brasil

This study aimed to identify the median duration of breastfeeding and associated factors in a cohort of 531 infants in two municipalities in the Recôncavo region, Bahia State, Brazil. Breastfeeding duration was estimated by survival analysis and its associations by the Cox multivariate model. Median duration of exclusive breastfeeding, mixed breastfeeding with complementary feeding, and total breastfeeding was 74.73, 211.25, and 432.63 days, respectively. Lack of prenatal care increased the risk of shortening exclusive breastfeeding by 173% (HR = 2.73; 95%CI: 1.89-3.93), [corrected] of adopting mixed breastfeeding with complementary feeding by 83% (HR = 1.83; [corrected] 95%CI: 1.06-3.16), and of discontinuing breastfeeding entirely by 38% (HR = 1.38; 95%CI: 1.06-1.81). Both maternal employment and residence in an urban area increased the risk of early breastfeeding cessation. Expansion of access to prenatal care and the safety network for employed mothers living in urban areas could increase breastfeeding duration in the target region.

Breastfeeding practice in the Brazilian capital cities and the Federal District: current status and advances

To present the breastfeeding (BF) indicators obtained in the Second Survey on Prevalence of Breastfeeding in the Brazilian Capitals and the Federal District and to analyze their evolution from 1999 to 2008. A cross-sectional study was conducted in children younger than 1 year old who participated in the second phase of the multivaccination campaign in 2008. We used two-stage cluster sampling. The questionnaire consisted of closed questions, including data on consumption of breast milk, other types of milk, and other foods on the day prior to the survey. We analyzed the prevalence of BF in the first hour of life; exclusive BF in children younger than 6 months; BF in children aged 9 to 12 months; and medians of exclusive BF and BF. The time variation of BF was established by comparing the medians of exclusive BF and BF in 1999 and 2008. We obtained data from 34,366 children. We found that 67.7% (95%CI 66.7-68.8) of the children were breastfed in the first hour of life; the prevalence of exclusive BF in children aged 0 to 6 months was 41% (95%CI 39.7-42.4), while the prevalence of BF in children aged 9 to 12 months was 58.7% (95%CI 56.8-60.7). There was an increase of 30.7 days in the median duration of exclusive BF and 45.7 days in the median of BF. There was a significant improvement in the breastfeeding prevalence in the last decade. However, further efforts are required so that Brazil can reach BF rates compatible with the recommendations of the World Health Organization.

Infant feeding practices among HIV-positive women in Dar es Salaam, Tanzania, indicate a need for more intensive infant feeding counselling.

To assess feeding practices of infants born to HIV-positive women in Dar es Salaam, Tanzania. These data then served as a proxy to evaluate the adequacy of current infant feeding counselling. A cross-sectional survey of infant feeding behaviours. Four clinics in greater Dar es Salaam in early 2008. A total of 196 HIV-positive mothers of children aged 6-10 months recruited from HIV clinics. Initiation of breast-feeding was reported by 95·4 % of survey participants. In the entire sample, 80·1 %, 34·2 % and 13·3 % of women reported exclusive breast-feeding (EBF) up to 2, 4 and 6 months, respectively. Median duration of EBF among women who ever breast-fed was 3 (interquartile range (IQR): 2·1, 4·0) months. Most non-breast-milk foods fed to infants were low in nutrient density. Complete cessation of breast-feeding occurred within 14 d of the introduction of non-breast-milk foods among 138 of the 187 children (73·8 %) who had ever received any breast milk. Of the 187 infants in the study who ever received breast milk, 19·4 % received neither human milk nor any replacement milks for 1 week or more (median duration of no milk was 14 (IQR: 7, 152) d). Infant feeding practices among these HIV-positive mothers resulted in infants receiving far less breast milk and more mixed complementary feeds than recommended, thus placing them at greater risk of both malnutrition and HIV infection. An environment that better enables mothers to follow national guidelines is urgently needed. More intensive infant feeding counselling programmes would very likely increase rates of optimal infant feeding.

Paternal Smoking and Breastfeeding in Xinjiang, PR China

A cohort of 1088 couples in Xinjiang, PR China, were recruited to study infant feeding practices and paternal smoking. Mothers were interviewed in hospital and at 0.5, 1.5, 2.5, 3.5, 4.5, and 6 months. Survival analysis was used to calculate breastfeeding rates in smokers and nonsmokers. The paternal smoking rate was 64.8% and maternal smoking rate 1.7% (P < .01). The rates for any breastfeeding in the smoking group were significantly lower than in the nonsmoking group from 3.5 months to 6 months (P < .05). The rates for exclusive breastfeeding in the paternal smoking group were lower than in the nonsmoking group from discharge to 6 months (P < .05). The median duration of exclusive breastfeeding in the paternal smoking group was shorter than in the nonsmoking group. Paternal smoking was a risk factor for stopping any breastfeeding (hazard risk, 1.84; 95% confidence interval, 1.11-3.04) and exclusive breastfeeding (hazard risk, 1.33; 95% CI, 1.09-1.64) compared with nonsmokers.

Age at the Introduction of Solid Foods During the First Year and Allergic Sensitization at Age 5 Years

The goal was to examine the relationship between age at the introduction of solid foods during the first year of life and allergic sensitization in 5-year-old children. We analyzed data from the Finnish Type 1 Diabetes Prediction and Prevention nutrition study, a prospective, birth cohort study. We studied 994 children with HLA-conferred susceptibility to type 1 diabetes mellitus for whom information on breastfeeding, age at the introduction of solid foods, and allergen-specific immunoglobulin E levels at 5 years was available. The association between age at the introduction of solid foods and allergic sensitization was analyzed by using logistic regression. The median duration of exclusive breastfeeding was 1.8 months (range: 0-10 months). After adjustment for potential confounders, late introduction of potatoes (>4 months), oats (>5 months), rye (>7 months), wheat (>6 months), meat (>5.5 months), fish (>8.2 months), and eggs (>10.5 months) was significantly directly associated with sensitization to food allergens. Late introduction of potatoes, rye, meat, and fish was significantly associated with sensitization to any inhalant allergen. In models that included all solid foods that were significantly related to the end points, eggs, oats, and wheat remained the most important foods related to sensitization to food allergens, whereas potatoes and fish were the most important foods associated with inhalant allergic sensitization. We found no evidence of reverse causality, taking into account parental allergic rhinitis and asthma. Late introduction of solid foods was associated with increased risk of allergic sensitization to food and inhalant allergens.

Alimentação complementar de lactentes em uma cidade desenvolvida no contexto de um país em desenvolvimento

To establish the timing for introducing supplementary foods in the diet of infants from the city of Campinas, state of São Paulo, Brazil. This cross-sectional study included 2 857 children younger than 2 years of age randomly selected from the city department of health live birth database between 2004 and 2005. The mothers answered a questionnaire that included 87 closed questions designed to collect information concerning socioeconomic status, breastfeeding, and timing of introduction of supplementary foods. Assessment of the mothers revealed that 13.5% were adolescents, 73.1% had completed elementary or high school education, 45.9% had technical level jobs, 6,7% had jobs requiring a university degree, and 2.7% were health professionals. On average, participants belonged to socioeconomic class C (ranging from A, highest, to E, lowest), but all socioeconomic classes were represented. The median duration of exclusive breastfeeding was 90 days (95%CI: 87.6-92.4). Water (95%CI: 118.6-121.4) and tea (95 CI%: 113.2-126.8) were introduced at a median of 120 days. Semi-solid foods (95%CI: 178.6-181,4) and powdered milk (95%CI: 169.0-191.0) were introduced at a median of 180 days. Powdered milk and soft drinks had been ingested by 39.1% and 2.1%, respectively, at 4 months, and by 63.2 and 69.1%, respectively, at 1 year of age. Shorter breastfeeding duration was observed for women with technical level jobs, those who were unemployed, and those without a partner. The median duration of exclusive breastfeeding was far from that recommended due to the offer of supplementary fluids. Supplementary foods were introduced precociously, especially sweets.

Determinants of breast-feeding in a Finnish birth cohort

To assess milk feeding on the maternity ward and during infancy, and their relationship to sociodemographic determinants. The validity of our 3-month questionnaire in measuring hospital feeding was assessed. A prospective Finnish birth cohort with increased risk to type 1 diabetes recruited between 1996 and 2004. The families completed a follow-up form on the age at introduction of new foods and age-specific dietary questionnaires. Type 1 Diabetes Prediction and Prevention (DIPP) project, Finland. A cohort of 5993 children (77 % of those invited) participated in the main study, and 117 randomly selected infants in the validation study. Breast milk was the predominant milk on the maternity ward given to 99 % of the infants. Altogether, 80 % of the women recalled their child being fed supplementary milk (donated breast milk or infant formula) on the maternity ward. The median duration of exclusive breast-feeding was 1.4 months (range 0-8) and that of total breast-feeding 7.0 months (0-25). Additional milk feeding on the maternity ward, short parental education, maternal smoking during pregnancy, small gestational age and having no siblings were associated with a risk of short duration of both exclusive and total breast-feeding. In the validation study, 78 % of the milk types given on the maternity ward fell into the same category, according to the questionnaire and hospital records. The recommendations for infant feeding were not achieved. Infant feeding is strongly influenced by sociodemographic determinants and feeding practices on the maternity wards. Long-term breast-feeding may be supported by active promotion on the maternity ward.

Evaluación del Impacto de la Implementación de la Iniciativa Hospital Amigable a los Bebés

Assessment of the Impact of Implementing the Baby-Friendly Hospital Initiative Objective: To evaluate the impact of the Baby-Friendly Hospital Initiative on the breastfeeding practices of mothers from the urban area of Montes Claros, MG, Brazil. Methods: A comparative analysis was performed of two cross-sectional breastfeeding indicator studies with randomized samples of children under 2 years of age. One study was carried out before and the other after the Baby-Friendly Hospital Initiative had been implemented throughout all public pregnancy and childbirth care services in the city. Kaplan-Meyer survival curves were constructed for different breastfeeding patterns. Log rank testing was used to calculate the level of significance of differences between curves for before and after the Initiative. Results: The survival curves demonstrate that breastfeeding rates increased during the study period. The log rank test detected significance for increases in all patterns of breastfeeding (p < 0.000). Median overall breastfeeding duration increased from 8.9 to 11.6 months and median duration of exclusive breastfeeding rose from 27 days to 3.5 months. Conclusions: Implementation of the Baby-Friendly Hospital Initiative in all public maternity units in Montes Claros significantly increased breastfeeding rates in the city. Since the ideal state of affairs has not yet been reached, further strategies must be implemented to promote and support breastfeeding practices. (Key words: Breastfeeding, healthcare project and program evaluation, human milk, breastmilk, health promotion).

Exclusive breastfeeding of Swedish children and its possible influence on the development of obesity: a prospective cohort study

BackgroundOverweight and obesity are increasing among children all over the world. Socio-economic factors may influence the development of overweight and obesity in childhood, and it has been proposed that breastfeeding may protect against obesity. The aim of our study was to examine the relationship between exclusive breastfeeding and obesity when potential confounders, such as socioeconomic factors, are considered.MethodsThe data analyzed was from ABIS (All Babies in Southeast Sweden), a prospective cohort study. All parents with children born between October 1, 1997 and October 1, 1999 in Southeast Sweden (n = 21,700) were asked to participate. Parents were asked to answer periodic questionnaires from the time of the child's birth (n = 16,058) until he/she was five years of age (n = 7,356). Cutoffs for overweight and obesity were defined according to Cole et al, age and gender adjusted. Short-term exclusive breastfeeding was defined as < 4 months of exclusive breastfeeding. Multiple logistic regressions were used to identify variables that predict the child's BMI (Body Mass Index) at five years of age.ResultsAt five years of age, 12.9% of the children in the study wereoverweight and 4.3% were obese. At the age of three months, 78.4% of the children were being breastfed exclusively. The median exclusive breastfeeding duration was four months. High maternal BMI > 30 (AOR = 1.07; CI = 1.05–1.09; P < 0.001), maternal smoking (AOR = 1.43; CI = 1.05–1.95; P = 0.023) and being a single parent (AOR = 2.10; CI = 1.43–3.09; P < 0.001) were associated with short-term exclusive breastfeeding (less than 4 months). Short-term exclusive breastfeeding was less common if one of the parents had a university degree (Mother: AOR = 0.74; CI = 0.61–0.90; P = 0.003 Father: AOR = 0.73; CI = 0.58–0.92; P = 0.008) or if the father was more than 37 years old (AOR = 0.74; CI = 0.55–0.99; P = 0.045). Short-term exclusive breastfeeding was associated with obesity in five-year-old children (simple logistic regression: OR = 1.44; CI = 1.00–2.07; P = 0.050), but when including other independent factors in the analysis, short-term exclusive breastfeeding did not attain statistical significance.ConclusionWe cannot exclude the possibility that exclusive breastfeeding influences weight development, but it does not seem to protect against obesity at five years of age.

Intervention to promote exclusive breast-feeding for the first 6 months of life in a high HIV prevalence area

We report on a nonrandomized intervention cohort study to increase exclusive breast-feeding rates for 6 months after delivery in HIV-positive and HIV-negative women in KwaZulu-Natal, South Africa. Lay counselors visited women to support exclusive breast-feeding: four times antenatally, four times in the first 2 weeks postpartum and then fortnightly to 6 months. Daily feeding practices were collected at weekly intervals by separate field workers. Cumulative exclusive breast-feeding rates from birth were assessed by Kaplan-Meier analysis and association with maternal and infant variables was quantified in a Cox regression analysis. One thousand, two hundred and nineteen infants of HIV-negative and 1217 infants of HIV-positive women were followed postnatally. Median duration of exclusive breast-feeding was 177 (R = 1-180; interquartile range: 150-180) and 175 days (R = 1-180; interquartile range: 137-180) in HIV-negative and HIV-positive women, respectively. Using 24-h recall, exclusive breast-feeding rates at 3 and 5 months were 83.1 and 76.5%, respectively, in HIV-negative women and 72.5 and 66.7%, respectively, in HIV-positive women. Using the most stringent cumulative data, 45% of HIV-negative and 40% of HIV-positive women adhered to exclusive breast-feeding for 6 months. Counseling visits were strongly associated with adherence to cumulative exclusive breast-feeding at 4 months, those who had received the scheduled number of visits were more than twice as likely to still be exclusively breast-feeding than those who had not (HIV-negative women: adjusted odds ratio: 2.07, 95% confidence interval: 1.56-2.74, P < 0.0001; HIV-positive women: adjusted odds ratio: 2.86, 95% CI 2.13-3.83, P < 0.0001). It is feasible to promote and sustain exclusive breast-feeding for 6 months in both HIV-positive and HIV-negative women, with home support from well trained lay counselors.

BREASTFEEDING AND ATOPIC DISEASE IN CHILDHOOD: THE GENESIS STUDY

INTRODUCTION: The prevalence of asthma and atopic disease in childhood is increasing yearly. A protective connection between breastfeeding and development of atopy has been suggested in several studies. OBJECTIVE: Our goal was to investigate the correlation between breastfeeding and atopy. METHODS: We screened 1525 children aged 2 to 5 years. Information on the outcome variables “ever wheezing,” “recurrent wheezing,” “diagnosed asthma,” “itchy rash,” “recurrent rash,” and “diagnosed atopic dermatitis” was obtained. Multiple logistic regression analysis was used to estimate the association of outcome variables with the independent variable (breastfeeding) after adjustment for gender and parental history of allergy. RESULTS: Median duration of exclusive breastfeeding was 1 month (range: 0–2 months). Children who were breastfed exclusively for &amp;gt;3 months had 28% (95% confidence interval [CI]: 0.53%–0.98%) and 29% (95% CI: 0.51%–1.00%) lower likelihood of ever developing wheezing and recurrent wheezing, respectively. Partial breastfeeding seemed to place the children at significantly greater risk for ever and recurrent wheezing when compared with exclusive breastfeeding. There was no significant difference between exclusive breastfeeding versus formula feeding. Of the ever-breastfed children, 15.2% developed itchy rash versus 10.9% of those who never breastfed. Girls had a significant lower odds ratio (OR) for ever wheezing (OR: 0.76 [95% CI: 0.62–0.94]) and “diagnosed asthma” (OR: 0.60 [95% CI: 0.43–0.85]). Of the children studied, 3.7% had a positive parental background for allergy. Parental history of allergy comprised a significant factor that indicated a greater OR for all outcome variables apart from “diagnosed asthma.” CONCLUSIONS: Breastfeeding seems to have a significant protective effect against the development of wheezing and asthma but not toward the development of skin atopy. A prospective randomized, controlled trial with longer follow-up time is required to confirm our findings.

Factors Associated with Duration of Exclusive Breastfeeding

To estimate the probabilities of various factors at various time intervals for duration of exclusive breastfeeding, the present study was done at the well baby clinic. Mothers with infants below one year of age were selected and interviewed. The median duration of exclusive breastfeeding (EBF) was found 6 months. Relationship between duration of EBF and practice of breastfeeding (on demand or at fixed time) was studied and found statistically not significant (p>0.05) by log rank test. Other factors affecting EBF were also studied like literacy, type of family and monthly family income. Median duration of EBF was found more (7 months) for illiterate women than for literate (6 months) and statistically significant (p 0.05). A statistically significant difference was observed while testing two different groups based on total family income.

Feeding Patterns of Brazilian Preterm Infants During the First 6 Months of Life, Londrina, Paraná, Brazil

The present study evaluated the breastfeeding practice of 278 preterm infants born at the University Hospital of Londrina, Paraná, Brazil, during hospitalization and in the first 6 months of life. Data were obtained from the hospital records, and the mothers were interviewed by home visit (75.5%) or by telephone (24.5%) when the children were 6 months old. Data were analyzed statistically using the Kaplan-Meier survival method and Cox's multivariate regression model. During hospitalization, 100% of the preterm infants received human milk and 31% received exclusive breastfeeding. The median duration of exclusive breastfeeding and breastfeeding was 63.5 and > 180 days, respectively. The prevalence of breastfeeding in the sixth month was 54.7%, and 6.8% of the infants were still exclusively breastfed. Pacifiers were used (currently using or ever used) by 127 (45.7%) preterm infants and were associated with a 1.67 times higher risk of interruption of exclusive breastfeeding.

Tendência do aleitamento materno em município da região centro-sul do estado de São Paulo: 1995-1999-2004

OBJETIVO: Avaliar a situação do aleitamento materno em 2004 no município de Botucatu, SP, e identificar sua tendência nos últimos 10 anos. MÉTODOS: Trata-se de um estudo epidemiológico, no qual foram comparados os resultados de 3 inquéritos populacionais transversais (1995-1999-2004), metodologicamente semelhantes, sobre a situação do aleitamento materno em crianças menores de 12 meses. Os dados foram obtidos em Campanhas de Multivacinação, a partir de questionário contendo um recordatório da alimentação das crianças no dia anterior à pesquisa. Para identificar a tendência dos diferentes tipos de aleitamento (aleitamento materno exclusivo, aleitamento materno predominante e aleitamento materno), foram comparadas as prevalências, segundo faixas etárias selecionadas (0-1 mês, 0-4 meses, 0-6 meses e 0-12 meses), nos 3 inquéritos. Os resultados foram submetidos a teste estatístico (teste z) para verificação das diferenças entre proporções. RESULTADOS: Para as crianças menores de 4 meses, houve aumento progressivo e de grande magnitude (19,1% em 1995 e 36,9% em 2004) do aleitamento materno exclusivo e diminuição do aleitamento materno predominante - diferenças estatisticamente significantes. O mesmo ocorreu para as crianças menores de 6 meses: 13,0% em aleitamento materno exclusivo em 1995, 29,6% em 2004, representando 128,0% de aumento. Com relação ao aleitamento materno, tanto para as crianças menores de 4 meses, quanto para as menores de 6 meses e de 1 ano, houve pequeno aumento de prevalência, mas as diferenças não foram estatisticamente significantes. A duração mediana do aleitamento materno exclusivo aumentou 14 dias (82,0%) e do aleitamento materno 85 dias (50,9%) no período de 10 anos. CONCLUSÃO: Com a elevação expressiva da prevalência de crianças menores de 6 meses em aleitamento materno exclusivo e o aumento da mediana da amamentação exclusiva e da amamentação, pode-se afirmar que a evolução do aleitamento no município foi favorável. Entretanto, a situação em 2004 ainda está distante das recomendações atuais sobre alimentação infantil.

Fatores associados com a duração do aleitamento materno

OBJETIVOS: Determinar os índices de aleitamento materno exclusivo e complementado e identificar variáveis que interferem na prática da amamentação no município de Itaúna (MG). MÉTODOS: Estudo longitudinal realizado com 246 mulheres assistidas na maternidade do Hospital Manoel Gonçalves, no município de Itaúna (MG). O acompanhamento das mães e recém-nascidos foi realizado mensalmente nos primeiros 12 meses após o parto ou até a interrupção da amamentação. A análise da duração do aleitamento materno exclusivo e complementado foi realizada utilizando procedimentos de análise de sobrevivência. O efeito das co-variáveis sobre o tempo de aleitamento foi avaliado através do modelo de regressão de Cox. RESULTADOS: A prevalência de aleitamento materno exclusivo no sexto mês foi de 5,3%, e de aleitamento materno aos 12 meses, 33,7%. A mediana de aleitamento materno exclusivo foi de 40 dias, e a mediana de aleitamento materno, 237 dias. A análise multivariada mostrou associação negativa (p < 0,05) entre o tempo de aleitamento materno exclusivo e as variáveis: intenção de amamentar (< 12 meses), peso do recém-nascido (< 2.500 g) e uso de chupeta. O menor tempo de aleitamento materno foi associado (p < 0,05) com idade materna (< 20 anos), número de consultas de pré-natal (< 5 e > 9 consultas), uso de álcool ou tabaco, tempo da primeira mamada (> 6 horas) e uso de chupeta. CONCLUSÕES: Os índices de aleitamento materno no município de Itaúna (MG) estão muito abaixo daqueles preconizados pela Organização Mundial da Saúde. As principais variáveis relacionadas negativamente ao tempo de aleitamento materno exclusivo e complementado estão associadas à assistência materno-infantil, sendo, portanto, passíveis de intervenção.

Factors associated with duration of breastfeeding

To determine rates of exclusive breastfeeding and of complementary feeding and to identify variables that interfere with breastfeeding in the municipality of Itaúna, MG, Brazil. A longitudinal study was undertaken enrolling 246 women who gave birth at the maternity unit of the Manoel Gonçalves Hospital, in Itaúna, MG. The mothers and their infants were seen monthly for the first 12 months after birth or until they stopped breastfeeding. Survival analysis procedures were used to study the duration of exclusive breastfeeding and of complementary feeding. The impact on breastfeeding duration of a series of co-variables was assessed by means of Cox regression modeling. The prevalence of exclusive breastfeeding at 6 months was 5.3%, and for breastfeeding at 12 months it was 33.7%. The median duration of exclusive breastfeeding was 40 days, and median breastfeeding duration was 237 days. Multivariate analysis demonstrated a negative association (p<0.05) between duration of exclusive breastfeeding and the following variables: intended breastfeeding duration (<12 months), birth weight of child (<2,500 g) and use of a pacifier. Shorter breastfeeding duration was associated (p<0.05) with maternal age (< 20 years), number of prenatal consultations (<5 and >9 consultations), use of alcohol or tobacco, delay before first feed (>6 hours) and use of a pacifier. Breastfeeding rates in Itaúna (MG) are well below those recommended by the World Health Organization. The principal variables with a negative relationship with duration of exclusive breastfeeding and of complementary feeding are related to mother and baby health care and, therefore, interventions are possible.

Assessment of the impact of implementing the Baby Friendly Hospital Initiative

To evaluate the impact of the Baby-Friendly Hospital Initiative on the breastfeeding practices of mothers from the urban area of Montes Claros, MG, Brazil. A comparative analysis was performed of two cross-sectional breastfeeding indicator studies with randomized samples of children under 2 years of age. One study was carried out before and the other after the Baby-Friendly Hospital Initiative had been implemented throughout all public pregnancy and childbirth care services in the city. Kaplan-Meyer survival curves were constructed for different breastfeeding patterns. Log rank testing was used to calculate the level of significance of differences between curves for before and after the Initiative. The survival curves demonstrate that breastfeeding rates increased during the study period. The log rank test detected significance for increases in all patterns of breastfeeding (p < 0.000). Median overall breastfeeding duration increased from 8.9 to 11.6 months and median duration of exclusive breastfeeding rose from 27 days to 3.5 months. Implementation of the Baby-Friendly Hospital Initiative in all public maternity units in Montes Claros significantly increased breastfeeding rates in the city. Since the ideal state of affairs has not yet been reached, further strategies must be implemented to promote and support breastfeeding practices.

The effect of time in the U.S. on the duration of breastfeeding in women of Mexican descent.

Although women of Mexican decent have high rates of breastfeeding, these rates may vary considerably by acculturation level. This study investigated whether increased years of residence in the U.S. is associated with poorer breastfeeding practices, including shorter duration of any and exclusive breastfeeding, in a population of low-income mothers of Mexican descent. Pregnant women (n = 490) were recruited from prenatal clinics serving a predominantly Mexican-origin population in an agricultural region of California. Women were interviewed during pregnancy, shortly postpartum, and when their child was 6 months, 1 year, 2 years, and 3.5 years of age. Increased years of residence in the U.S. was associated with decreased likelihood of initiating breastfeeding and shorter duration of exclusive and any breastfeeding. Median duration of exclusive breastfeeding was 2 months for women living in the U.S. for 5 years or less, 1 month for women living in the U.S. for 6 to 10 years, and less than one week for women living in the U.S. for 11 years or more, or for their entire lives (lifetime residents). After controlling for maternal age, education, marital status and work status, lifetime residents of the U.S. were 2.4 times more likely to stop breastfeeding, and 1.5 times more likely to stop exclusive breastfeeding, than immigrants who had lived in the U.S. for 5 years or less. Efforts are needed to encourage and support Mexican-origin women to maintain their cultural tradition of breastfeeding as they become more acculturated in the U.S.

Breastfeeding practices in a public health field practice area in Sri Lanka: a survival analysis

BackgroundExclusive breastfeeding up to the completion of the sixth month of age is the national infant feeding recommendation for Sri Lanka. The objective of the present study was to collect data on exclusive breastfeeding up to six months and to describe the association between exclusive breastfeeding and selected socio-demographic factors.MethodsA clinic based cross-sectional study was conducted in the Medical Officer of Health area, Beruwala, Sri Lanka in June 2006. Mothers with infants aged 4 to 12 months, attending the 19 child welfare clinics in the area were included in the study. Infants with specific feeding problems (cleft lip and palate and primary lactose intolerance) were excluded. Cluster sampling technique was used and consecutive infants fulfilling the inclusion criteria were enrolled. A total of 219 mothers participated in the study. The statistical tests used were survival analysis (Kaplan-Meier survival curves and Cox proportional Hazard model).ResultsAll 219 mothers had initiated breastfeeding. The median duration of exclusive breastfeeding was four months (95% CI 3.75, 4.25). The rates of exclusive breastfeeding at 4 and 6 months were 61.6% (135/219) and 15.5% (24/155) respectively. Bivariate analysis showed that the Muslim ethnicity (p = 0.004), lower levels of parental education (p < 0.001) and being an unemployed mother (p = 0.021) were important associations of early cessation of exclusive breastfeeding.
