Feeding outcome in breast-fed term babies supplemented by cup or bottle

OBJECTIVE: To describe the feeding method at discharge from midwifery care of term babies supplemented either by cup or bottle while in hospital. DESIGN: A retrospective review of the obstetric and midwifery records of 531 consecutively born babies. SETTING: A large maternity unit, with an integral General Practitioner Unit, in an inner city in the south of England. PARTICIPANTS: 63 term breast-feeding babies; 30 supplemented by cup and 33 supplemented by bottle. MAIN OUTCOME MEASURE: Breast feeding on discharge from midwifery care. FINDINGS: There were no significant differences between the bottle and cup supplementation groups in relation to feeding outcome (OR 1 94 95% CI 0.61, 6.31), or in the length of time from the beginning of supplementation to leaving hospital (median difference 1 95% CI 0, 1) or discharge from midwifery care (median difference 0 95% CI, -1, 1). Babies who received supplements of expressed breast milk, as opposed to artificial milk, were more likely to be supplemented by cup (OR 4 29, 95% CI 0.9, 26.91; p = 0.05), but were not more likely to be discharged from midwifery care breast feeding (OR 3.79, 95% CI 0.69, 38.36). CONCLUSION: Owing to the small scale and retrospective nature of this survey, its results must be viewed with caution. However, given the apparent lack of evidence in this area, prospective work should be undertaken to examine the most appropriate method of supplementation for term babies. Generalisation from work related to babies in special care baby units is no longer acceptable.     

A randomised trial of low dose aspirin for primiparae in pregnancy

Objective To investigate whether low dose aspirin medication given to primiparous women provides benefit in preventing pre-eclampsia or intrauterine growth retardation.
Design Randomised double-blind controlled trial of low dose aspirin and placebo in pregnancy.
Population Residents of the parishes of Kingston and St Andrew, Jamaica; 6275 primiparae enrolled between 12 and 32 weeks of gestation.
Main outcome measures Hypertensive disorders of pregnancy (including pre-eclampsia and eclampsia), preterm delivery, and low birthweight. In addition, to assess whether enrolment early, rather than late had more beneficial effect. Possible adverse effects on the woman and her infant were monitored.
Results Of enrolled primiparae, 97% were followed throughout pregnancy. There were no differences between those on aspirin and those on placebo in the development of hypertensive disorders (e.g. for a rise in diastolic pressure of 25 mmHg the odds ratio [OR] was 1.02 [95% CI 0.86–1.211; for proteinuric pre-eclampsia OR 1.15 [95% CI 0.92–1.44]; eclampsia OR 0.82 [95% CI 0.44–1.531); except for oedema which was significantly less prevalent in those on aspirin (OR 0.85 [95% CI 0.75–0.961). Women on aspirin were not significantly less likely to deliver preterm (OR 0.93 [95% CI 0–79-1.091) or have a larger fetus (mean birthweight difference 18 g [95% CI -9 to 451). They were, however, significantly more likely to suffer from bleeding disorders antenatally, intrapartum and postpartum; for postpartum haemorrhage OR 1.40 (95% CI 1.13–1-73).
Conclusions This trial shows that low dose aspirin has no consistent beneficial effect in primiparae.     

In‐Hospital Formula Supplementation of Breastfed Babies: A Population‐Based Survey

Abstract: Background: In‐hospital formula supplementation of breastfed newborns is commonplace despite its negative association with breastfeeding duration. Although several studies have described the use of formula supplementation, few have explored the factors that may be associated with its use. The aim of this study was to explore factors associated with in‐hospital formula supplementation using data from a large Australian population‐based survey. Methods: All women who gave birth in September and October 2007 in two Australian states were mailed questionnaires 6 months after the birth. Women were asked how they fed their baby while in hospital after the birth. Multivariable logistic regression was used to explore specified a priori factors associated with in‐hospital formula supplementation. Results: Of 4,085 women who initiated breastfeeding, 23 percent reported their babies receiving formula supplementation. Breastfed babies had greater odds of receiving formula supplementation if their mother was primiparous (adj. OR = 2.16; 95% CI: 1.76–2.66); born overseas and of non‐English‐speaking background (adj. OR = 2.03; 95% CI: 1.56–2.64); had a body mass index more than 30 (adj. OR = 2.27; 95% CI: 1.76–2.95); had an emergency cesarean section (adj. OR = 1.72; 95% CI: 1.3–2.28); or the baby was admitted to a special care nursery (adj. OR = 2.72; 95% CI: 2.19–3.4); had a birthweight less than 2,500 g (adj. OR = 2.02; 95% CI: 1.3–3.15) or was born in a hospital not accredited with Baby‐Friendly Hospital Initiative (BFHI) (adj. OR = 1.53; 95% CI: 1.2–1.94). Conclusions: The number of factors associated with in‐hospital formula supplementation suggests that this practice is complex. Some results, however, point to an opportunity for intervention, with the BFHI appearing to be an effective strategy for supporting exclusive breastfeeding. (BIRTH 38:4 December 2011)     

Association of maternal fever during labor with neonatal and infant morbidity and mortality.

OBJECTIVE: To examine the association of intrapartum fever with infant morbidity and early neonatal (0-6 days) and infant (0-364 days) death. METHODS: We carried out a retrospective cohort analysis among singleton live births in the United States for the period 1995-1997 using the National Center for Health Statistics linked birth-infant death cohort data. RESULTS: Among the 11,246,042 singleton live births during the study period, intrapartum fever (at least 38C) was recorded in 1.6%. Intrapartum fever was associated with early neonatal (adjusted odds ratio [OR], 95% confidence interval [CI] for preterm and term infants respectively: 1.32; 1.11, 1.56 and 1.67; 1.14, 2.46) and infant (OR, 95% CI for preterm and term, respectively: 1.31; 1.14, 1.51 and 1.27; 1.01, 1.59) death among nulliparous mothers. Among preterm infants of parous mothers, intrapartum fever was associated with early neonatal (OR 1.29, 95% CI 1.01, 1.64) death. In the combined analyses (infants of nulliparous and parous mothers), intrapartum fever was a strong predictor of infection-related death. These associations were stronger among term (OR 3.16, 95% CI 1.56, 6.40 for early neonatal; OR 1.75, 95% CI 1.20, 2.57 for infant death) than preterm infants (OR 1.52, 95% CI 1.15, 2.00 for early neonatal; OR 1.29, 95% CI 1.05, 1.57 for infant death). Intrapartum fever was also a risk factor for meconium aspiration syndrome, hyaline membrane disease, neonatal seizures, and assisted ventilation. CONCLUSION: Intrapartum fever is an important predictor of neonatal morbidity and infection-related mortality.     

A case-control study of intrapartum stillbirths.

OBJECTIVE: To determine antenatal and intrapartum risk factors for intrapartum stillbirths in a total population. DESIGN: Matched case-control study. SETTING: Western Australia 1980-1983. SUBJECTS: Intrapartum stillbirths of > or = 1000 g birthweight (cases) and liveborn infants (controls) individually matched for year of birth, plurality, sex and birthweight of infant and race of mother. RESULTS: Intrapartum stillbirths were more likely than controls to have had placental abruption (OR = 9.55, CI = 2.09-43.69), fetal distress (OR = 4.64, CI = 1.92-11.19), cord prolapse (OR = 10.00, CI = 1.17-85.60) and unhealthy placentas (OR = 2.26, CI = 1.13-4.52), and more likely to have been born by vaginal breech manoeuvre (OR = 3.51, CI = 1.40-8.80) and emergency caesarean section (OR = 2.15, CI = 1.13-4.10); mothers of intrapartum stillbirths were less likely to have had no labour (OR = 0.14, CI = 0.04-0.55) and to have been delivered normally (OR = 0.20, CI = 0.10-0.40). Mothers of cases born by emergency caesarean section had longer labours than mothers of controls born by this method. All intrapartum stillbirths with breech presentation were born by vaginal breech manoeuvre compared with only 53% of the controls; the remainder of the controls were born by caesarean section. CONCLUSIONS: Results indicate that little could have been done early in pregnancy to prevent the intrapartum stillbirths as no antenatal risk factors predicted these deaths. Most of the risk factors identified related to labour and delivery problems. Considering cases born by emergency caesarean section, delivery of the mother earlier in labour may have prevented some of the deaths.     

Effect of Operative Delivery in the Second Stage of Labor on Breastfeeding Success

Abstract: Background: Operative delivery rates are currently rising in many countries, but the effects of this factor on the initiation and duration of breastfeeding are unclear. The purpose of this study was to evaluate breastfeeding success after instrumental vaginal delivery or cesarean section at full dilatation, and to investigate whether timing of discharge after operative delivery affects breastfeeding rates. Methods: A prospective cohort study was conducted of 393 women with term, singleton, live, cephalic pregnancies who required delivery in theater during the second stage of labor between February 1999 and February 2000. Postal questionnaires were mailed to participants at 6 weeks and 1 year. Logistic regression models were used to explore the relationships between infant feeding and mode of delivery, controlling for factors previously correlated with breastfeeding success. Results: Rates of exclusive breastfeeding at discharge and 6 weeks postpartum were 70 and 44 percent, respectively. No significant differences occurred when instrumental vaginal delivery was compared with cesarean section, adjusted OR 0.84 (95% CI 0.50, 1.41) and 1.15 (95% CI 0.69, 1.93) respectively. Breastfeeding rates after failed instrumental delivery were similar to those after immediate cesarean section, adjusted OR 0.99 (95% CI 0.72, 1.38) and 1.28 (95% CI 0.91, 1.78). Women who had a longer in‐patient stay after cesarean section were more likely to achieve exclusive breastfeeding at hospital discharge (78% vs 66%, p = 0.03). Conclusions: Method of operative delivery in the second stage of labor does not appear to influence initiation or duration of exclusive breastfeeding. A longer inpatient stay may help cesarean‐delivered women to initiate breastfeeding. (BIRTH 30:4 December 2003)     

Association between Intrapartum Interventions and Breastfeeding Duration

Introduction : Few women who reside in Hong Kong exclusively breastfeed, and one‐half stop breastfeeding within the first few months. There is little research in this population on the association between intrapartum interventions and breastfeeding duration. Methods : A sample of 1280 mother‐infant pairs were recruited from the obstetric units of 4 public hospitals in Hong Kong and followed prospectively for 12 months or until the infant was weaned. The outcome variables for this analysis were the duration of any and exclusive breastfeeding. Predictor variables were 4 intrapartum interventions: receipt of opioid pain medication, induction versus spontaneous labor, epidural administration, and mode of birth. We used Cox proportional hazards modeling to assess the impact of intrapartum interventions on the duration of any and exclusive breastfeeding, and we constructed Kaplan‐Meier survival curves to evaluate the cumulative impact of multiple intrapartum interventions on breastfeeding outcomes. Results : Bivariate analysis showed that induction of labor (hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.09‐1.41), opioid pain medication (HR, 1.21; 95% CI, 1.06‐1.37), and having an emergency cesarean birth (HR, 1.22; 95% CI, 1.01‐1.48) were associated with a shorter duration of any breastfeeding. Induction of labor (HR, 1.23; 95% CI, 1.08‐1.39) and having an emergency cesarean birth (HR, 1.25; 95% CI, 1.05‐1.51) were associated with a shorter duration of exclusive breastfeeding. After controlling for known confounding variables, there was no longer any association between individual intrapartum interventions and the duration of any or exclusive breastfeeding. The median duration of breastfeeding for participants who experienced a natural birth with no intrapartum interventions was 9 weeks compared with 5 weeks for participants who experienced at least 3 intrapartum interventions. Discussion : Clinicians working with new breastfeeding mothers should focus on providing additional support to mothers who experience a difficult labor and birth with multiple interventions to improve their breastfeeding experiences.     

How much influence do women in Sweden have on caesarean section? A follow-up study of women's preferences in early pregnancy

OBJECTIVE: to investigate factors associated with having a caesarean section, with special emphasis on women's preferences in early pregnancy. DESIGN: a cohort study using data from questionnaires in early pregnancy and 2 months after childbirth, and data from the Swedish Medical Birth Register. SETTING: women were recruited from 97% of all antenatal clinics in Sweden at their booking visit during 3 weeks between 1999 and 2000, and followed up 2 months after birth. PARTICIPANTS: a total of 2878 Swedish-speaking women were included in the study (87% of those who consented to participate and 63% of all women eligible for the study). FINDINGS: Of 236 women who wished to have their babies delivered by caesarean section when asked in early pregnancy, 30.5% subsequently had an elective caesarean section and 14.8% an emergency caesarean section. The logistic regression analyses showed that, a preference for caesarean section in early pregnancy (odds ratio [OR] 9.63, 95% confidence interval [CI] 5.94-15.59), a medical diagnosis (OR 9.03, 95% CI 5.68-14.34), age (OR 1.08, 95% CI 1.03-1.13), parity (OR 0.58, 95% CI 0.37-0.91), a previous elective caesarean section (OR 15.11, 95% CI 6.83-33.41) and a previous emergency caesarean section (OR 18.29, 95% CI 10.00-33.44) was associated with having an elective caesarean section. Having an emergency caesarean section was associated with a preference for a caesarean section (OR 2.59, 95% 1.61 to 4.18), a medical diagnosis (OR 4.12, 95% CI 2.91-5.88), age (OR 1.08, 95% CI 1.05-1.12), primiparity (OR 3.34, 95% CI 1.78-6.27), a previous emergency caesarean section (OR 10.69, 95% CI 6.03-18.94), and a previous elective caesarean section (OR 7.21, 95% CI 2.90-17.92). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: a woman's own preference about caesarean section was associated with the subsequent mode of delivery. Asking women about their preference regarding mode of delivery in early pregnancy may increase the opportunity to provide adequate support and possibly also to reduce the caesarean section rate.     

Associations of drugs routinely given in labour with breastfeeding at 48 hours: analysis of the Cardiff Births Survey

Background  Little is known about how breastfeeding rates are affected by drugs routinely administered in labour.
Objective  To examine a large obstetric data set to investigate potentially modifiable associations between drugs routinely administered in labour and breastfeeding in healthy women and infants.
Design  Retrospective cohort.
Setting  The Cardiff (Wales UK) Births Survey.
Population  A total of 48 366 healthy women delivering healthy singleton babies at term.
Methods  Analysis of the Cardiff Births Survey.
Main outcome measure  Association between intrapartum medications and breastfeeding at 48 hours postpartum.
Results  At 48 hours, 43.3% (20 933/48 366) women were not breastfeeding. Regression analysis confirmed previously reported associations of lower breastfeeding rates with certain demographic indicators, epidural analgesia, intramuscular opioid analgesia and ergometrine. Novel associations were detected with oxytocin alone or in combination with ergometrine administered for prevention of postpartum haemorrhage (PPH), which were associated with reductions of 6–8%, (intramuscular oxytocin OR 0.75, 95% CI 0.61–0.91, intravenous oxytocin OR 0.68, 95% CI 0.57–0.82, oxytocin/ergometrine OR 0.77, 95% CI 0.65–0.91), and prostaglandins administered for induction of labour. The associations were maintained when subgroups, such as primiparous women, women whose labours were neither induced nor augmented, and women not receiving epidural analgesia were considered.
Conclusion  Prospective studies on drugs in labour are needed to investigate potential causative associations between intrapartum medications and breastfeeding. Such studies will delineate the optimum balance between breastfeeding and maternal health, most importantly the risk of PPH.     

Risk factors for surgical site infection following caesarean section in England: results from a multicentre cohort study

Please cite this paper as: Wloch C, Wilson J, Lamagni T, Harrington P, Charlett A, Sheridan E. Risk factors for surgical site infection following caesarean section in England: results from a multicentre cohort study. BJOG 2012;119:1324-1333. Objective To assess the frequency and risk factors for surgical site infection following caesarean section. Design Prospective multicentre cohort study. Setting Fourteen NHS hospitals in England, April to September 2009. Population Women who underwent caesarean section at participating hospitals during designated study periods. Methods Infections that met standard case definitions were identified through active follow up by healthcare staff during the hospital stay, on return to hospital, during midwife home visits and through self-completed patient questionnaires. Main outcome measure Surgical site infection within 30?days of operation. Results Altogether, 9.6% (394/4107) of women in the study developed a postsurgical infection following caesarean section with 0.6% (23/4107) readmitted for treatment of the infection. Being overweight (body mass index [BMI] 25-30?kg/m(2) odds ratio [OR] 1.6, 95% confidence interval [95% CI] 1.2-2.2) or obese (BMI 30-35?kg/m(2) OR 2.4, 95% CI 1.7-3.4; BMI?>?35?kg/m(2) OR 3.7, 95% CI 2.6-5.2) were major independent risk factors for infection (compared with BMI 18.5-25?kg/m(2) ). There was a suggestion that younger women, and operations performed by associate specialist and staff grade surgeons had a greater odds of developing surgical site infection with OR 1.9, 95% CI 1.1-3.4 (<20?years versus 25-30?years), and OR 1.6, 95% CI 1.0-2.4 (versus consultants), respectively. Conclusions This study identified high rates of postsurgical infection following caesarean section. Given the number of women delivering by caesarean section in the UK, substantial costs will be incurred as a result of these infections. Prevention of these infections should be a clinical and public health priority.     

Impact of early infant feeding practices on mortality in low birth weight infants from rural Ghana.

OBJECTIVE: To assess the impact of early infant feeding practices on low birth weight- (LBW) specific neonatal mortality in rural Ghana. STUDY DESIGN: A total of 11 787-breastfed babies were born between July 2003 and June 2004 and survived to day 2. Overall, 3411 (30.3%) infants had weight recorded within 48 h. Two hundred and ninety-six (8.7%) infants were <2.5 kg and 15 died in the neonatal period. Associations were examined using multivariate logistic regression. RESULT: Initiation of breastfeeding after day 1 was associated with a threefold increase in mortality risk (adjusted odds ratio (adjOR) 3.23, 95% confidence interval (95% CI) (1.07-9.82)) in infants aged 2 to 28 days. Prelacteal feeding was associated with a threefold significantly increased mortality risk (adjOR 3.12, 95% CI (1.19-8.22)) in infants aged 2 to 28 days but there was no statistically significant increase in risk associated with predominant breastfeeding (adjOR 1.91, 95% CI (0.60-6.09)). There were no modifications of these effects by birth weight. The sample size was insufficient to allow assessment of the impact of partial breastfeeding. CONCLUSION: Improving early infant feeding practices is an effective, feasible, low-cost intervention that could reduce early infant mortality in LBW infants in developing countries. These findings are especially relevant for sub-Saharan Africa where many LBW infants are born at home, never taken to a health facility and mortality rates are unacceptably high.     

Low prepregnant body mass index and breastfeeding practices.

The relationship of low prepregnant body mass index with breastfeeding was investigated in 1272 women who delivered a term infant with birthweight > or = 2500 g at the San Paolo Hospital in Milan, Northern Italy. Underweight was defined using the Institute of Medicine's cutoff of 19.8 kg/m(2). Women were interviewed via telephone through 12 months postdelivery about breastfeeding practices. Education level (high versus low, odds ratio [OR], 1.41), primiparity (OR, 1.35), vaginal delivery (OR, 0.74), and birthweight of the infant (normal versus high, OR, 1.89) were associated with low, as opposed to normal, pre-pregnant body mass index. After adjustment for these confounders, no difference was found between underweight and normal weight women for initiation or duration of breastfeeding (mean adjusted difference, 0.4; 95% confidence interval [95% CI], -0.1 to 0.9 months) or exclusive breastfeeding (0.1 [95% CI, -0.1 to 0.3] months). Underweight mothers of healthy term infants may not be at increased risk for not initiating or shorter breastfeeding.     

Breastfeeding duration rates and factors affecting continued breastfeeding among infants born at an inner-city US Baby-Friendly hospital.

The effects of Baby-Friendly status on breastfeeding duration in the United States have not been published. The objectives of this study were to obtain breastfeeding rates at 6 months among babies born in a US Baby-Friendly hospital and to assess factors associated with continued breastfeeding at 6 months. The authors randomly selected 350 medical records of infants born in 2003 at Baby-Friendly Boston Medical Center. Of 336 eligible infants, 248 (74%) attended the 6-month well-child visit and 37.1% (92/248) were breastfeeding at 6 months. In multivariate logistic regression, the likelihood of breastfeeding at 6 months was decreased by presence of a feeding problem in the hospital (AOR 0.27; 95% CI 0.07-0.99), whereas the likelihood of breastfeeding at 6 months increased with maternal age (AOR 1.05; 95% CI 1.00-1.10) and for mothers born in Africa (AOR 4.29; 95% CI 1.36-13.5) or of unrecorded birthplace (AOR 3.29; 95% CI 1.38-7.85). Breastfeeding duration is traditionally poor in low-income, black populations in the United States. Among a predominantly low-income and black population giving birth at a US Baby-Friendly hospital, breastfeeding rates at 6 months were comparable to the overall US population.     

Obstetric outcomes subsequent to intrauterine death in the first pregnancy

Objective  To compare obstetric outcomes in the pregnancy subsequent to intrauterine death with that following live birth in first pregnancy.
Design  Retrospective cohort study.
Setting  Grampian region of Scotland, UK.
Population  All women who had their first and second deliveries in Grampian between 1976 and 2006.
Methods  All women delivering for the first time between 1976 and 2002 had follow up until 2006 to study their next pregnancy. Those women who had an intrauterine death in their first pregnancy formed the exposed cohort, while those who had a live birth formed the unexposed cohort.
Main outcome measures  Maternal and neonatal outcomes in the second pregnancy, including pre-eclampsia, placental abruption, induction of labour, instrumental delivery, caesarean delivery, malpresentation, prematurity, low birthweight and stillbirth.
Results  The exposed cohort ( n = 364) was at increased risk of pre-eclampsia (OR 3.1, 95% CI 1.7–5.7); placental abruption (OR 9.4, 95% CI 4.5–19.7); induction of labour (OR 3.2, 95% CI 2.4–4.2); instrumental delivery (OR 2.0, 95% CI 1.4–3.0); elective (OR 3.1, 95% CI 2–4.8) and emergency caesarean deliveries (OR 2.1, 95% CI 1.5–3.0); and prematurity (OR 2.8, 95% CI 1.9–4.2), low birthweight (OR 2.8, 95% CI 1.7–4.5) and malpresentation (OR 2.8, 95% CI 2.0–3.9) of the infant as compared with the unexposed cohort ( n = 33 715). The adjusted odds ratio for stillbirth was 1.2 and 95% CI 0.4–3.4.
Conclusion  While the majority of women with a previous stillbirth have a live birth in the subsequent pregnancy, they are a high-risk group with an increased incidence of adverse maternal and neonatal outcomes.     

New postnatal urinary incontinence: obstetric and other risk factors in primiparae

OBJECTIVE: To identify obstetric and other risk factors for urinary incontinence that occurs during pregnancy or after childbirth. DESIGN: Questionnaire survey of women. SETTING: Maternity units in Aberdeen (Scotland), Birmingham (England) and Dunedin (New Zealand). POPULATION: A total of 3405 primiparous women with singleton births delivered during 1 year. METHODS: Questionnaire responses and obstetric case note data were analysed using multivariate analysis to identify associations with urinary incontinence. MAIN OUTCOME MEASURES: Urinary incontinence at 3 months after delivery first starting in pregnancy or after birth. RESULTS: The prevalence of urinary incontinence was 29%. New incontinence first beginning after delivery was associated with older maternal age (oldest versus youngest group, OR 2.02, 95% CI 1.35-3.02) and method of delivery (caesarean section versus spontaneous vaginal delivery, OR 0.28, 95% CI 0.19-0.41). There were no significant associations with forceps delivery (OR 1.18, 95% CI 0.92-1.51) or vacuum delivery (OR 1.16, 95% CI 0.83-1.63). Incontinence first occurring during pregnancy and still present at 3 months was associated with higher maternal body mass index (BMI>25, OR 1.68, 95% CI 1.16-2.43) and heavier babies (birthweight in top quartile, OR 1.56, 95% CI 1.12-2.19). In these women, caesarean section was associated with less incontinence (OR 0.39, 95% CI 0.27-0.58) but incontinence was not associated with age. CONCLUSIONS: Women have less urinary incontinence after a first delivery by caesarean section whether or not that first starts during pregnancy. Older maternal age was associated with new postnatal incontinence, and higher BMI and heavier babies with incontinence first starting during pregnancy. The effect of further deliveries may modify these findings.     

Health workers' support for breastfeeding in Ibadan, Nigeria.

Breastfeeding in Nigeria is universal, and exclusive breastfeeding was introduced in 1992, yet no study has assessed health workers' support for breastfeeding at the grassroots level. This study assessed health workers' tangible support for breastfeeding at primary care facilities in Ibadan and factors affecting it, including knowledge of and attitudes toward breastfeeding. Among the 386 workers, there was moderate support for breastfeeding (median score = 15.0, maximum = 20). Following multivariate analysis, young age of worker (20-29 years; odds ratio [OR] = 2.9, 95% confidence interval [CI]: 1.2-6.8), more than 5 years of post-training experience (OR = 2.3, 95% CI: 1.2-4.4), senior profession (OR = 2.1, 95% CI: 1.0-4.4), high breastfeeding knowledge scores (OR = 2.5, 95% CI: 1.4-4.5), and sufficient opportunities to practice tangible breastfeeding support (OR = 4.3, 95% CI: 2.4-7.7) were found to predict tangible breastfeeding support. Deliberate efforts should be made to incorporate continuing education workshops to better prepare health professionals for their role in providing tangible breastfeeding support at the primary care level.     

Psychiatric and substance use disorders as risk factors for low birth weight and preterm delivery

OBJECTIVE: We examined the associations between psychiatric and substance use diagnoses and low birth weight (LBW), very low birth weight (VLBW), and preterm delivery among all women delivering in California hospitals during 1995. METHODS: This population-based retrospective cohort analysis used linked hospital discharge and birth certificate data for 521,490 deliveries. Logistic regression analyses were conducted to assess the associations between maternal psychiatric and substance use hospital discharge diagnoses and LBW, VLBW, and preterm delivery while controlling for maternal demographic and medical characteristics. RESULTS: Women with psychiatric diagnoses had a significantly higher risk of LBW (adjusted odds ratio [OR] 2.0; 95% confidence interval [CI] 1.7, 2.3), VLBW (OR 2.9; 95% CI 2.1, 3.9), and preterm delivery (OR 1.6; 95% CI 1.4, 1.9) compared with women without those diagnoses. Substance use diagnoses were also associated with higher risk of LBW (OR 3.7; 95% CI 3.4, 4.0), VLBW (OR 2.8; 95% CI 2.3, 3.3), and preterm delivery (OR 2.4; 95% CI 2.3, 2.6). CONCLUSION: Maternal psychiatric and substance use diagnoses were independently associated with low birth weight and preterm delivery in the population of women delivering in California in 1995. Identifying pregnant women with current psychiatric disorders and increased monitoring for preterm and low birth weight delivery among this population may be indicated.     

Parental Attitudes Toward Breastfeeding: Their Association with Feeding Outcome at Hospital Discharge

Abstract: Background : A woman chooses to breastfeed for many reasons. Recent research, however, suggests that parental attitudes toward breastfeeding are stronger predictors of infant feeding choice than commonly cited sociodemographic factors. The objective of the current study was to compare the infant feeding attitudes of expectant couples, and to determine to what degree their individual attitudes during early pregnancy were predictive of the method of infant feeding at discharge from hospital. Methods : A convenience sample of pregnant women (gestational age 8–12 weeks), who were attending maternity clinics in Glasgow, Scotland, in 2000, completed the 17‐item Iowa Infant Feeding Attitude Scale (IIFAS), together with their partners. Results : The IIFAS was completed by 108 expectant couples. At discharge from hospital 49.1 percent of women were exclusively breastfeeding, and 50.9 percent were exclusively formula‐feeding. A woman's total infant feeding attitude score was significantly correlated with her partner's score(r = 0.67, p < 0.001). There was no difference in the infant feeding attitudes of formula‐feeding couples(p = 0.987), but breastfeeding women tended to be more supportive of breastfeeding than their partners(p = 0.022). Maternal, but not paternal, infant feeding attitude was a significant predictor of the choice of feeding method (OR = 1.16 95% CI = 1.09–1.24). Conclusions : Infant feeding attitudes tended to be shared by expectant couples. Maternal infant feeding attitude was a better predictor of feeding choice than were demographic factors. Paternal attitudes were not found to be independently associated with feeding choice. Identification of women with neutral infant feeding attitudes using the IIFAS may be an effective way of targeting interventions at those women who are most likely to be receptive to such programs.     

What are the Risks Associated with Formula Feeding? A Re‐Analysis and Review

Abstract: Background: Most infant feeding studies present infant formula use as “standard” practice, supporting perceptions of formula feeding as normative and hindering translation of current research into counseling messages supportive of exclusive breastfeeding. To promote optimal counseling, and to challenge researchers to use exclusive breastfeeding as the standard, we have reviewed the scientific literature on exclusive breastfeeding and converted reported odds ratios to allow discussion of the “risks” of any formula use. Methods: Studies indexed in PubMed that investigated the association between exclusive breastfeeding and otitis media, asthma, types 1 and 2 diabetes, atopic dermatitis, and infant hospitalization secondary to lower respiratory tract diseases were reviewed. Findings were reconstructed with exclusive breastfeeding as the standard, and levels of significance calculated. Results: When exclusive breastfeeding is set as the normative standard, the re‐calculated odds ratios communicate the risks of any formula use. For example, any formula use in the first 6 months is significantly associated with increased incidence of otitis media (OR: 1.78, 95% CI: 1.19, 2.70 and OR: 4.55, 95% CI: 1.64, 12.50 in the available studies; pooled OR for any formula in the first 3 mo: 2.00, 95% CI: 1.40, 2.78). Only shorter durations of exclusive breastfeeding are available to use as standards for calculating the effect of “any formula use” for type 1 diabetes, asthma, atopic dermatitis, and hospitalization secondary to lower respiratory tract infections. Conclusions: Exclusive breastfeeding is an optimal practice, compared with which other infant feeding practices carry risks. Further studies on the influence of presenting exclusive breastfeeding as the standard in research studies and counseling messages are recommended. (BIRTH 37:1 March 2010)
