          Abstract

          Background

          Exclusive breastfeeding (EBF) is a simple and cost-effective intervention to improve child health and survival. Effective EBF has been estimated to avert 13% - 15% of under-five mortality and contribute to reduce mother to child transmission of HIV. The prevalence of EBF for infant less than six months is low in most developing countries, including Tanzania (50%). While the Tanzania Demographic Health Survey collects information on overall EBF prevalence, it does not evaluate factors influencing EBF. The aim of this paper was to determine the prevalence and predictors of exclusive breastfeeding in urban and rural areas in Kilimanjaro region.

          Methods

          A population-based cross-sectional study was conducted between June 2010 to March 2011 among women with infants aged 6–12 months in Kilimanjaro. Multi-stage proportionate to size sampling was used to select participants from all the seven districts of the region. A standardized questionnaire was used to collect socio-demographic, reproductive, alcohol intake, breastfeeding patterns and nutritional data during the interviews. Estimation on EBF was based on recall since birth. Multivariable logistic regression was used to obtain independent predictors of EBF.

          Results

          A total of 624 women participated, 77% (483) from rural areas. The prevalence of EBF up to six months in Kilimanjaro region was 20.7%, without significant differences in the prevalence of EBF up to six months between urban (22.7%) and rural areas (20.1%); (OR = 0.7, 95% CI 0.5,1.4).

          In multivariable analysis, advice on breastfeeding after delivery (Adjusted odds ratio, AOR = 2.6, 95% CI 1.5, 4.6) was positively associated with EBF up to six months. Compared to married/cohabiting and those who do not take alcohol, single mothers (AOR = 0.4, 95% CI 0.2, 0.9) and mothers who drank alcohol (AOR = 0.4, 95% CI 0.3, 0.7) had less odds to practice EBF up to six months.

          Conclusion

          Prevalence of EBF up to six months is still low in Kilimanjaro, lower than the national coverage of 50%. Strengthening of EBF counseling in all reproductive and child health clinics especially during antenatal and postnatal periods may help to improve EBF rates.

          Early exclusive breastfeeding reduces the risk of postnatal HIV-1 transmission and increases HIV-free survival.

          The promotion of exclusive breastfeeding (EBF) to reduce the postnatal transmission (PNT) of HIV is based on limited data. In the context of a trial of postpartum vitamin A supplementation, we provided education and counseling about infant feeding and HIV, prospectively collected information on infant feeding practices, and measured associated infant infections and deaths. A total of 14 110 mother-newborn pairs were enrolled, randomly assigned to vitamin A treatment group after delivery, and followed for 2 years. At baseline, 6 weeks and 3 months, mothers were asked whether they were still breastfeeding, and whether any of 22 liquids or foods had been given to the infant. Breastfed infants were classified as exclusive, predominant, or mixed breastfed. A total of 4495 mothers tested HIV positive at baseline; 2060 of their babies were alive, polymerase chain reaction negative at 6 weeks, and provided complete feeding information. All infants initiated breastfeeding. Overall PNT (defined by a positive HIV test after the 6-week negative test) was 12.1%, 68.2% of which occurred after 6 months. Compared with EBF, early mixed breastfeeding was associated with a 4.03 (95% CI 0.98, 16.61), 3.79 (95% CI 1.40-10.29), and 2.60 (95% CI 1.21-5.55) greater risk of PNT at 6, 12, and 18 months, respectively. Predominant breastfeeding was associated with a 2.63 (95% CI 0.59-11.67), 2.69 (95% CI 0.95-7.63) and 1.61 (95% CI 0.72-3.64) trend towards greater PNT risk at 6, 12, and 18 months, compared with EBF. EBF may substantially reduce breastfeeding-associated HIV transmission.

            Do baby-friendly hospitals influence breastfeeding duration on a national level?

            In Switzerland, the Baby-Friendly Hospital Initiative (BFHI) proposed by the United Nations Children's Fund (UNICEF) was introduced in 1993 to promote breastfeeding nationwide. This study reports results of a national study of the prevalence and duration of breastfeeding in 2003 throughout Switzerland and analyzes the influence of compliance with UNICEF guidelines of the hospital where delivery took place on breastfeeding duration. Between April and September 2003, a random sample of mothers who had given birth in the past 9 months in Switzerland received a questionnaire on breastfeeding and complementary feeding. Seventy-four percent of the contacted mothers (n = 3032) participated; they completed a 24-hour dietary recall questionnaire and reported the age at first introduction of various foods and drinks. After excluding questionnaires with missing information relevant for the analyses, we analyzed data for 2861 infants 0 to 11 months of age, born in 145 different health facilities. Because it was known whether each child was born in a designated baby-friendly hospital (45 hospitals) or in a health facility in the process of being evaluated for BFHI inclusion (31 facilities), we were able to assess a possible influence of the BFHI on breastfeeding success. For this purpose, we merged individual data with hospital data on compliance with the UNICEF guidelines, from a data source collected on an annual basis for quality monitoring of designated baby-friendly hospitals and health facilities in the evaluation process. Information on actual compliance with the guidelines allowed us to investigate the relationship between breastfeeding outcomes and compliance with UNICEF guidelines. We were also able to compare the breastfeeding results with those for non-baby-friendly health facilities. The comparison was based on median durations of exclusive, full, and any breastfeeding calculated for each group. To allow for other known influencing factors, we calculated adjusted hazard ratios by using Cox regression; we also conducted logistic regression analyses with the 24-hour dietary recall data, to calculate adjusted odds ratios for validation of results from the retrospectively collected data. In 2003, the median duration of any breastfeeding was 31 weeks at the national level, compared with 22 weeks in 1994, and the median duration of full breastfeeding was 17 weeks, compared with 15 weeks in 1994. The proportion of exclusively breastfed infants 0 to 5 months of age was 42% for infants born in baby-friendly hospitals, compared with 34% for infants born elsewhere. Breastfeeding duration for infants born in baby-friendly hospitals, compared with infants born in other hospitals, was longer if the hospital showed good compliance with the UNICEF guidelines (35 weeks vs 29 weeks for any breastfeeding, 20 weeks vs 17 weeks for full breastfeeding, and 12 weeks vs 6 weeks for exclusive breastfeeding). To control for differences in the study population between the different types of health facilities, hazard and odds ratios were calculated as described above, taking into account socioeconomic and medical factors. Although the analysis of the retrospective data showed clearly that the duration of exclusive and full breastfeeding was significantly longer if delivery occurred in a baby-friendly hospital with high compliance with the UNICEF guidelines, whereas this effect was less prominent in other baby-friendly health facilities, this difference was less obvious in the 24-hour recall data. Only for the duration of any breastfeeding could a positive effect be seen if delivery occurred in a baby-friendly hospital with high compliance with the UNICEF guidelines. Known factors involved in the evaluation of baby-friendly hospitals showed the expected influence, on the individual level, on duration of exclusive, full, and any breastfeeding. If a child had been exclusively breastfed in the hospital, the median duration of exclusive, full, and any breastfeeding was considerably longer than the mean for the entire population or for those who had received water-based liquids or supplements in the hospital. A positive effect on breastfeeding duration could be shown for full rooming in, first suckling within 1 hour, breastfeeding on demand, and also the much-debated practice of pacifier use. After controlling for medical problems before, during, and after delivery, type of delivery, well-being of the mother, maternal smoking, maternal BMI, nationality, education, work, and income, all of the factors were still significantly associated with the duration of full, exclusive, or any breastfeeding. Our results support the hypothesis that the general increase in breastfeeding in Switzerland since 1994 can be interpreted in part as a consequence of an increasing number of baby-friendly health facilities, whose clients breastfeed longer. Nevertheless, several alternative explanations for the longer breastfeeding duration for deliveries that occurred in baby-friendly hospitals can be discussed. In Switzerland, baby-friendly hospitals actively use their certification by UNICEF as a promotional asset. It is thus possible that differences in breastfeeding duration are attributable to the fact that mothers who intend to breastfeed longer would choose to give birth in a baby-friendly hospital and these mothers would be more willing to comply with the recommendations of the UNICEF guidelines. Even if this were the case, however, this selection bias would not explain the differences in breastfeeding duration between designated baby-friendly health facilities with higher compliance with the UNICEF guidelines and those with lower compliance. Especially this last point strongly supports a beneficial effect of the BFHI, because mothers do not know how well hospitals comply with the UNICEF program. The fact that breastfeeding rates have generally improved even in non-baby-friendly health facilities may be indirectly influenced by the BFHI; its publicity and training programs for health professionals have raised public awareness of the benefits of breastfeeding, and the number of professional lactation counselors has increased continuously. Breastfeeding prevalence and duration in Switzerland have improved in the past 10 years. Children born in a baby-friendly health facility are more likely to be breastfed for a longer time, particularly if the hospital shows high compliance with UNICEF guidelines. Therefore, the BFHI should be continued but should be extended to include monitoring for compliance, to promote the full effect of the BFHI.

              Prevalence and predictors of 6-month exclusive breastfeeding among Canadian women: a national survey

              Background In spite of the evidence supporting the importance of breastfeeding during the first year of life, data on breastfeeding practices remain limited in Canada. The study aimed to examine the prevalence and predictors of 6-month exclusive breastfeeding among Canadian women. Methods The analysis was based on the Maternity Experience Survey targeting women aged ≥ 15 years who had singleton live births between February 2006 - May 2006 in the Canadian provinces and November 2005 - February 2006 in the territories. The main outcome was exclusive breastfeeding based on the World Health Organization definition. Socioeconomic, demographic, maternal, pregnancy and delivery related variables were considered for a multivariate logistic regression using stepwise modeling. Bootstrapping was performed to account for the complex sampling design. Results The sample size in this study was 5,615 weighted to represent 66,810 Canadian women. While ever breastfeeding was 90.3%, the 6-month exclusive breastfeeding rate was 13.8%. Based on the regression model, having higher years of education, residing in the Northern territories and Western provinces, living with a partner, having had previous pregnancies, having lower pre-pregnancy body mass index and giving birth at older age were associated with increased likelihood of 6-month exclusive breastfeeding. Moreover, smoking during pregnancy, Caesarean birth, infant's admission to the intensive care unit and maternal employment status before 6 months of infant's age were negatively associated with exclusive breastfeeding. Mothers choosing to deliver at home were more likely to remain exclusively breastfeeding for 6 months (Odds Ratio: 5.29, 95% Confidence Interval: 2.95-9.46). Conclusions The 6-month exclusive breastfeeding rate is low in Canada. The study results constitute the basis for designing interventions that aim to bridge the gap between the current practices of breastfeeding and the World Health Organization recommendation.
