The effect of an area-based intervention on breastfeeding rates in Victoria, Australia

Objectives
Best Start is an area-based early childhood intervention where projects are developed and implemented through a community partnership. A core tenet of the initiative is that implementing projects through a partnership generates greater value than would be expected if projects were undertaken independently by partner members. In this study we examine whether: (1) Best Start is effective in increasing the proportion of infants being fully breastfed at 3 months and 6 months. (2) The quality of community partnerships is a potential mechanism for change.

Methods
Best Start was implemented in Victoria, Australia. The study examined breastfeeding rates before and after Best Start in sites with Best Start breastfeeding projects compared to the rest of state. The relationship between partnership quality scores and breastfeeding percentages was also examined. Both analyses controlled for socioeconomic and demographic differences and clustering by area.

Results
Best Start targeted some of the most socially disadvantaged communities in Victoria. In the 3 years of its operation, the rates of fully breastfeeding at 3 months (OR 1.30, 95% CI 1.14–1.47) and 6 months (OR 1.33, 95% CI 1.1–1.61) increased in Best Start sites compared to the rest of the state. Quality of partnership scores was positively associated with increased percentages of fully breastfeeding (3 months = OR 1.03, 95% CI 1.01–1.06; 6 months = OR 1.03, 95% CI 0.98–1.08).

Conclusions
These results suggest that area-based interventions are effective in increasing percentages of fully breastfeeding. The study also supported the idea that developing quality community partnerships had a positive influence on their success.

Atopic disease and breastfeeding - cause or consequence?

Background

A number of studies have observed an association between breast-feeding and increased risk of development of asthma and eczema. It has been proposed that these results might be due to early signs of atopic disease in the infant causing mothers to prolong breast-feeding.

Objective

We sought to determine whether early symptoms of atopic disease (eczema, food reaction, or asthma) or positive skin prick test responses reduce the likelihood of ceasing breast-feeding.

Methods

A prospective birth cohort of 620 infants from Melbourne, Australia, was used. Telephone interviews every 4 weeks were conducted until 64 weeks and then again at 78 and 104 weeks to determine duration of breast-feeding (both exclusive and total) and evidence of atopic disease. Because of the varying time of onset of atopic symptoms, they were modeled as time-varying covariates in Cox models.
Results

Only 52 (8.4%) infants did not establish breast-feeding, whereas an additional 103 (25.0%) did not establish exclusive breast-feeding. Early signs of atopic disease or sensitization were independently associated with an approximately 28% reduction in risk of ceasing exclusive breast-feeding (adjusted hazard ratio, 0.72; 95% CI, 0.53-0.97); P = .029), but there was no evidence for a relationship with risk of ceasing breast-feeding completely (adjusted hazard ratio, 1.12; 95% CI, 0.92-1.37; P = .262).
Conclusion

Early signs of atopic disease might prolong the duration of exclusive breast-feeding. This could mask a protective effect of breast-feeding or even result in breast-feeding appearing to be a risk factor for the development of atopic diseases. Future investigation of the relationship between breast-feeding and atopic diseases should consider this possibility.

Issues of power and control within women's experience of breastfeeding following childbirth

In this interpretive study, six women who have had some difficulty with breastfeeding, tell of their experiences of breastfeeding following childbirth. These stories are discussed using the feminist poststructuralist theory of discourse analysis, as presented by Weedon (1987). The women's stories reveal a wide range of experiences, and conflicting discourses, many of which relate to issues of power and control surrounding breastfeeding.

Influence of peers on breastfeeding discontinuation among new parents : the Melbourne InFANT Program

OBJECTIVE We aimed to investigate whether the proportion of breastfeeding mothers in first-time parent groups influenced the likelihood of ceasing breastfeeding and whether this was independent of socioeconomic position.
METHODS Data were from 501 mothers (from 62 first-time parent groups initiated ~6 weeks after birth) who provided data at the baseline and mid-intervention assessments of the Melbourne Infant Feeding, Activity, and Nutrition Trial. Parent groups were divided into those in which ≤25% of mothers had ceased breastfeeding by 6 weeks (low-cessation groups) and those in which >25% had ceased by 6 weeks (high-cessation groups).
RESULTS With the exclusion of mothers who had already ceased breastfeeding by 6 weeks, the proportion of mothers who ceased breastfeeding between the time of parent group initiation (6 weeks) and 6 months was higher in high-cessation groups than in low-cessation groups (37.4% vs 21.7%; P = .001). After adjustment for maternal age, BMI, employment, and education and area-level socioeconomic position, membership in a group in which a large proportion of mothers had ceased breastfeeding by 6 weeks was strongly related to cessation of breastfeeding before 6 months (odds ratio: 2.1 [95% confidence interval: 1.3–3.3]).
CONCLUSIONS Attendance at parent groups where peers are breastfeeding infants of a similar age may have an important influence on the continuation of breastfeeding to 6 months. First-time parent groups or other similar groups may be an important setting in which to promote the continuation of breastfeeding.

Breastfeeding mothers consume more vegetables and a greater variety of fruits and vegetables than non-breastfeeding peers : the influence of socioeconomic position

Aim:  This study compared the diets of breastfeeding and non-breastfeeding mothers from socioeconomically diverse regions of Melbourne to determine whether breastfeeding is a marker for healthier maternal dietary intakes.

Methods:  This cross-sectional study obtained information via self-reported questionnaire from 529 first-time Melbourne mothers. Breastfeeding status was determined when the children were 3.9 months. Diet information was obtained using a validated Food Frequency Questionnaire. Maternal diet was assessed by seven indicators: average daily intake of fruit, vegetables, non-core drinks, non-core sweet snacks, non-core savoury snacks, variety of fruit and variety of vegetables eaten in the preceding 12 months. Associations between breastfeeding status and each dietary variable were assessed using linear regression analyses. Socioeconomic position, maternal body mass index and the cluster-based sampling design were controlled for.

Results:  Of the 529 subjects, 70% were breastfeeding their child. Compared with non-breastfeeding mothers, breastfeeding mothers were found to consume more serves of vegetables (P= 0.001), a greater variety of fruit and vegetables (P= 0.001 and P≤ 0.001 respectively), and sweet snacks were consumed more frequently (P= 0.006). Differences were observed between low and high socioeconomic position mothers for fruit serves (P= 0.003), vegetable serves (P= 0.010) and fruit variety (P= 0.006). These associations persisted after controlling for socioeconomic position and maternal body mass index.

Conclusions:  The association between infant feeding (breastfeeding) and some aspects of maternal diet provides further evidence suggesting a link between maternal and child diets from a younger age than previously examined.

Commentary : Fatty acids, breastfeeding and Autism Spectrum Disorder

Fatty acid deficiencies are linked to Autism Spectrum Disorder. This commentary discusses the protective role of breastfeeding and the urgency of research into the human infant's intake of colostrum to prevent fatty acid deficiency.

Breastfeeding and infant sleep patterns : an Australian population study

Objective : Our purpose was to determine if babies breastfed at 6 months of age were more likely to wake at night and less likely to sleep alone than formula-fed babies.

Patients and Methods : Data were drawn from the first wave of The Longitudinal Study of Australian Children, an ongoing, nationally representative study of the growth and development of Australia's children. The 4507 participants met the criteria for this study. The measures examined infant sleep problems as the outcome and breastfeeding at 6 months of age as the exposure in addition to the demographic data, maternal mental health, infant birthweight and gestational age at delivery.

Results : After adjustment for covariates, reports by mothers of infants that breastfed at 6 months of age suggested infants were 66% more likely to wake during the night and 72% more likely to report difficulty sleeping alone. However, breastfeeding had a strongly protective effect on wheezing, coughing, snoring and breathing problems, and it was not associated with restless sleep or problems getting to sleep for the infant.

Conclusions : Breastfeeding was found to be associated with increased night waking and this is consistent with other studies. There are biological reasons why this might be required to ensure breastfeeding continues to 6 months and beyond. The current low rates of sustained breastfeeding in many Western countries needs to be reconsidered in relation to parental and public health practices promoting prolonged nocturnal infant sleep patterns.

A longitudinal study of the effect of psychosocial factors on exclusive breastfeeding duration

Objective
to examine the effect of psychosocial factors on exclusive breastfeeding duration to six months postpartum

Design
longitudinal, prospective questionnaire based study.

Setting
participants were recruited from a publically funded antenatal clinic located in the western metropolitan region of Melbourne, Victoria, Australia and asked to complete questionnaires at three time points; 32 weeks pregnancy, two months postpartum and six months postpartum.

Participants
the participants were 125 pregnant women aged 22–44 years.

Measurements and findings
psychosocial variables such as breastfeeding self-efficacy, body attitude, psychological adjustment, attitude towards pregnancy, intention, confidence and motivation to exclusively breastfeed and importance of exclusive breastfeeding were assessed using a range of psychometrically validated tools. Exclusive breastfeeding behaviour up to six months postpartum was also measured. At 32 weeks gestation a woman׳s confidence to achieve exclusive breastfeeding was a direct predictor of exclusive breastfeeding duration to six months postpartum. At two months postpartum, psychological adjustment and breastfeeding self-efficacy were predictive of exclusive breastfeeding duration. Finally, at six months postpartum, psychological adjustment, breastfeeding self-efficacy, confidence to maintain and feeling fat were directly predictive of exclusive breastfeeding duration.

Psychosocial correlates of exclusive breastfeeding duration to six months postpartum

 In Australia 17% of infants are exclusively breastfed to six months postpartum. This thesis examined the effect of psychosocial factors on women’s ability to maintain exclusive breastfeeding. The thesis demonstrated the paucity of research in this area and the importance of psychosocial factors such as breastfeeding self-efficacy and psychological adjustment in women’s exclusive breastfeeding outcomes.

Interventions designed to promote exclusive breastfeeding in high-income countries: a systematic review
