Household Food Insecurity,Breastfeeding, and Related Feeding Practices in US Infants and Toddlers: Results From NHANES 2009–2014

ObjectiveTo examine the relationships among food insecurity, breastfeeding, and other related feeding practices by race/ethnicity among US infants and toddlers.DesignNational Health and Nutrition Examination Surveys 2009–2014, a nationally representative cross-sectional survey.ParticipantsInfants and toddlers aged 0–24 months with complete data on household food security status (n = 2,069).Main Outcome MeasuresInitiation of breastfeeding (yes or no), duration of breastfeeding, and age of introduction to foods/drinks.AnalysisDifferences in feeding practices by food security status were tested in survey-weighted, stratified multiple regression models.ResultsBreastfeeding initiation rates among non-Hispanic whites, Hispanics, and non-Hispanic blacks were estimated at 80.0%, 77.5%, and 57.4%, respectively (P < .001). A total of 43% of infants and toddlers were introduced to foods/drinks before 4 months. After adjusting for household income, education, and other covariates, food insecurity was not a significant predictor of poor feeding behaviors.Conclusions and ImplicationsRacial/ethnic disparities existed, with non-Hispanic black infants at the highest risk for never being breastfed, nor to continue through the recommended period of breastfeeding. Food insecurity was not shown to affect breastfeeding and other infant feeding practices directly. Further investigation is needed to understand whether food insecurity, through stress and other sociostructural pathways, mediates poor infant feeding practices.     

The Australian Feeding Infants and Toddler Study (OzFITS 2021): Breastfeeding and Early Feeding Practices

The Australian Feeding Infants and Toddler Study 2021 (OzFITS 2021) is a nationwide survey of Australian caregivers’ infant and toddler feeding practices. Here, we describe breastfeeding rates and duration, use of breastmilk substitutes, and introduction of complementary (solid) foods, including common food allergens. Caregivers (n = 1140) were recruited by a digital marketing company and were interviewed using a structured telephone questionnaire to obtain information. Breastfeeding was initiated in 98% of infants, but the duration of exclusive breastfeeding to six months was less than 1%. Nearly 40% of children continued to receive breastmilk beyond one year, with 10% of toddlers receiving breastmilk at two years. One-quarter of infants were introduced to solid foods between 4 to 5 months, and nearly all infants had received solid foods by 7 months. New guidelines encourage the early introduction of potential food allergens to reduce the risk of allergy, and by 12 months, over 90% of children had been given eggs and peanuts. One-third of children received no breastmilk substitutes during their first year. One-third of infants first received breastmilk substitutes following birth and before discharge from the hospital. Of these infants, 30% ceased breastmilk substitute use after discharge. Our findings suggest a high rate of continued breastfeeding with 44% receiving breastmilk beyond 1 year. One approach to increase the duration of exclusive breastfeeding is to reduce breastmilk substitute use while in hospital.     

Transitions in infants’ and toddlers’ beverage patterns

ObjectiveTo describe transitions and patterns in infants’ and toddlers’ beverage intakes, with focus on nonmilk beverages.DesignA cross-sectional study was conducted by telephone to obtain a 24-hour dietary recall of infants’ and toddlers’ food intakes, as reported by mothers or other primary caregivers.SubjectsA nationwide sample of infants and toddlers (n=3,022) ages 4 to 24 months, who participated in the Feeding Infants and Toddlers Study (FITS).AnalysesBeverages were categorized as total milks (ie, breast milk, infant formulas, cow’s milk, soy milk, goat’s milk), 100% juices, fruit drinks, carbonated beverages, water, and “other.” Analyses included means ± standard deviations, percentages, frequencies, nutrient densities, and linear regression.ResultsBeverages provided 84% of total daily food energy for infants 4 to 6 months of age, decreasing to 36% at ages 19 to 24 months. Apple juice and apple-flavored fruit drinks were the most frequently consumed beverages in the 100% juice and fruit drink categories, respectively. Juices, fruit drinks, and carbonated beverages appeared to displace milk in toddlers’ diets (P<.0001).Applications/conclusionsThis research shows that beverages make important contributions to infants’ and toddlers’ energy and nutrient needs, but they must be wisely chosen. Registered dietitians should advise parents and caregivers that excessive intakes of any beverage, including milks and 100% juices, may displace other foods and beverages in the diet and/or contribute to excess food energy (kcal). Further research is needed to define excessive amounts in each beverage category, and such guidance could be very useful to parents and caregivers of infants and toddlers.     

Breastfeeding Practice in Zhejiang Province, PR China, in the Context of Melamine-contaminated Formula Milk

A prospective cohort study of 1,520 mothers from Zhejiang province of China was undertaken to determine the duration of breastfeeding and associated factors during the first six months postpartum. Most (95.3%) mothers had introduced complementary foods by six months, making them at risk from contaminated infant formula. The mean duration of ‘any breastfeeding’ was greater than 180 days but only 48 days for ‘exclusive breastfeeding’. Factors relating to cessation of any breastfeeding were maternal age, timing of the breastfeeding decision, admission of the infant to a special-care nursery, return of the mother to work, the early introduction of water and/or other complementary foods, and their location of residence. The introduction of infant formula before three months was positively associated with the late decision to breastfeed, births in city, and infants being given a prelacteal feed. To combat the melamine disaster, strategies to improve the duration of breastfeeding must be developed taking these factors into account.Key words: Breastfeeding, Cohort studies, Disasters, Exclusive breastfeeding, Melamine, Melamine disasters, Prospective studies, China     

Breastfeeding and introduction of solid foods in Swedish infants: the All Babies in Southeast Sweden study

The aim of this report is to describe breastfeeding duration and introduction of foods in Swedish infants born 1997-9, in relation to current recommendations. A secondary aim is to examine breastfeeding duration and introduction of certain allergenic foods in allergy-risk families (for whom allergy-preventive advice has been issued). Out of 21,700 invited infants, screening questionnaires were completed for 16,070 infants after delivery. Parents to 11,081 infants completed a follow-up questionnaire regarding breastfeeding and introduction of foods and 9849 handed in detailed food diaries at 1 year of age. The percentages of infants who were exclusively breast-fed at 3, 6 and >or=9 months of age were 78.4, 10.1 and 3.9, respectively. The corresponding percentages for partial breastfeeding were 87.8, 68.9 and 43.6. Gluten-containing foods were introduced to 66% of infants between 4 and 6 months, as recommended at the time of the study, and one-quarter had stopped breastfeeding when gluten was introduced. More than 90% of parents introduced the first sample of solid food during months 4-6, as recommended. Fish and eggs had been introduced during the first year in 43% and 29%, respectively, of infants with atopic heredity. Exclusive breastfeeding duration and time of introduction of solid foods, including gluten, seemed to have been in line with Swedish recommendations at the time, although gluten was often introduced late, and not during ongoing breastfeeding as recommended. The adherence to allergy-preventive advice was less than optimal in infants with atopic heredity.     

Meningococcal serogroup B vaccine (4CMenB): Booster dose in previously vaccinated infants and primary vaccination in toddlers and two-year-old children

ObjectiveThe multicomponent, recombinant serogroup B vaccine, 4CMenB, is approved in Europe, Canada and Australia from two months of age. We investigated persistence to booster doses at 12 months of age following infant vaccination, and immune response to catch-up vaccination of toddlers and children up to two years of age.MethodsWe assessed persistence of immune responses after one year in participants vaccinated as infants, and responses to two doses at 12–15 or 24–26 months of age in vaccine-naïve children, as serum bactericidal activity with human complement (hSBA) against indicator strains for four vaccine antigens. Adverse events were recorded after each vaccination.ResultsHigh antibody titers were induced against all four 4CMenB components following booster vaccination in infant-primed toddlers and after two doses in previously unvaccinated toddlers or two-year-olds. Antibodies waned over 12 months, particularly those against NZ OMV. Systemic reactogenicity in toddlers was lower than in infants, and lower again in vaccine-naïve two-year-olds. Local reactogenicity was common in all groups.ConclusionsFour infant or two toddler 4CMenB vaccinations elicit immune responses believed to be protective for the first two years of life, which can be boosted. Reactogenicity is lower in toddlers than in infants.     

Commercial Baby Food Consumption and Dietary Variety in a Statewide Sample of Infants Receiving Benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children

Dietary variety and exposure to fruits and vegetables in infancy have been associated with nutritional benefits and later acceptance of these foods. The objective of this study was to examine the prevalence of fruit and vegetable commercial baby food consumption and its relation to dietary variety during infancy. A cross-sectional statewide telephone survey of 733 Maryland mothers and infants receiving benefits from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) was conducted between July 2004 and July 2005. A 24-hour dietary recall was examined to assess infant dietary variety. Among infants from birth to age 5 months, 54% had consumed complementary foods in the past 24 hours; 60% received commercial baby foods. Among infants aged 6 to 12 months, 98% had consumed complementary foods in the past 24 hours; 81% received commercial baby foods. In the latter age range, the average daily number of different types of fruits and vegetables consumed was 1.5±1.2, range 0 to 6). In a multivariate model, infants aged 6 to 12 months who received commercial baby foods consumed a greater variety of fruits and vegetables (β=.54, 95% confidence interval 0.26-0.84; P<0.001) than infants who did not, characterized by a diet that was lower in white potatoes (14% vs 22%) and higher in dark-green (6% vs 5%) and deep-yellow (35% vs 10%) vegetables. Commercial baby food is consumed by a majority of WIC infants, although many mothers introduce it before the recommended age of 6 months. Among infants aged 6 to 12 months, commercial baby food is associated with dietary variety in fruits and vegetables. By encouraging consumption of fruits and vegetables after 6 months of age, either through the provision of commercial baby foods and/or education and resources related to the preparation of fruits and vegetables for infants, WIC can increase dietary variety and appropriate introduction of complementary foods among infants.     

Added Sugars Intake among US Infants and Toddlers

BackgroundLimited information is available on added sugars consumption in US infants and toddlers.ObjectivesTo present national estimates of added sugars intake among US infants and toddlers by sociodemographic characteristics, to identify top sources of added sugars, and to examine trends in added sugars intake.DesignCross-sectional analysis of 1 day of 24-hour dietary recall data.Participants/settingA nationally representative sample of US infants aged 0 to 11 months and toddlers aged 12 to 23 months (n=1,211) during the period from 2011 through 2016 from the National Health and Nutrition Examination Survey. Trends were assessed from 2005-2006 through 2015-2016 (n=2,795).Main outcome measuresAmong infants and toddlers, the proportion consuming any added sugars, the average amount of added sugars consumed, percent of total energy from added sugars, and top sources of added sugars intake.Statistical analysisPaired t tests were used to compare differences by age, sex, race/Hispanic origin, family income level, and head of household education level. Trends were tested using orthogonal polynomials. Significance was set at P<0.05.ResultsDuring 2011 to 2016, 84.4% of infants and toddlers consumed added sugars on a given day. A greater proportion of toddlers (98.3%) consumed added sugars than infants (60.6%). The mean amount of added sugars toddlers consumed was also more compared with infants (5.8 vs 0.9 tsp). Non-Hispanic black toddlers (8.2 tsp) consumed more added sugars than non-Hispanic Asian (3.7 tsp), non-Hispanic white (5.3 tsp), and Hispanic (5.9 tsp) toddlers. A similar pattern was observed for percent energy from added sugars. For infants, top sources of added sugars were yogurt, baby food snacks/sweets, and sweet bakery products; top sources among toddlers were fruit drinks, sugars/sweets, and sweet bakery products. The mean amount of added sugars decreased from 2005-2006 through 2015-2016 for both age groups; however, percent energy from added sugars only decreased among infants.ConclusionAdded sugars intake was observed among infants/toddlers and varied by age and race and Hispanic origin. Added sugars intake, as a percent of energy, decreased only among infants from 2005 to 2016.     

Infant feeding patterns in the Finnish type I diabetes prediction and prevention nutrition study cohort

OBJECTIVE: To investigate infant feeding patterns during the first 2 y and their relation to sociodemographic factors. DESIGN: A population-based cohort study. SETTING: Oulu and Tampere University Hospital district areas 1996-1999, Finland. SUBJECTS AND METHODS: All newborn infants (n=675) with increased genetic risk for type I diabetes were invited to the study in 1996-1997. Of these, 429 (64%) completed the dietary follow-up form by the time they reached 2 y of age. RESULTS: The median duration of exclusive breastfeeding (BF) was 1.8 months (range 0-6 months) and that of total BF 7.0 months (0.3-25 months). Among the infants 20% were exclusively breastfed at least 4 months (recommendation 4-6 months). Infants were introduced to infant formula at the median age of 1.8 months (range 0-25 months) and other supplementary foods at the median age of 3.5 months (1-6 months). Infant's ponderal index at birth was inversely associated with the duration of total BF. The age of introduction of supplementary foods correlated positively with the duration of total BF. Longer parental education and increased maternal age were associated with a longer duration of BF and older age at introduction of supplementary foods. Infant formula and other supplementary foods were added earlier to the diet of the boys than that of the girls. CONCLUSION: Duration of breastfeeding in Finland is shorter than recommended. Compliance with the current recommendations on the timing of introduction of first supplementary food and dairy products is relatively poor. The diet during infancy seems to be conspicuously influenced by the duration of parental education, maternal age and the sex of the infant.

Timing of Introduction of Complementary Foods to US Infants,National Health and Nutrition Examination Survey 2009-2014

Background

Although there has been inconsistency in recommendations regarding the optimal time for introducing complementary foods, most experts agree that introduction should not occur before 4 months. Despite recommendations, studies suggest that 20% to 40% of US infants are introduced to foods at younger than 4 months. Previous studies focused on the introduction of solid foods and are not nationally representative.

Improved general health status in an unselected infant population following an allergen-reduced dietary intervention programme: the ZUFF-STUDY-PROGRAMME Part II: infant growth and health status to age 6 months

Summary Aim of the study. An allergen-reduced dietary intervention programme with strict dietary requirements was implemented over the first four months of life in an unselected population-based infant cohort and compared to a non-intervention cohort (the ZUFF study). Recommendations for the dietary programme in the intervention cohort were extended, but not strictly implemented, until the end of month six. The intervention was based on breastfeeding, a moderate whey hydrolysate formula (pHF), and delayed introduction of weaning foods with a high allergenicity. This study was a prospective, controlled, and unblinded study, the first to assess the effects of an allergen-reduced, pHF-based early nutritional programme in a broad unselected infant population. Because overall healthy development of the infant is a major objective of any nutritional programme, the study evaluated the effects of the dietary intervention on infant growth and general health status rather than specific allergic manifestations. Part I of this paper gave results for nutritional behaviour only, and Part II gives results for growth and general health status during the intervention period through the sixth month of life. Methods. Assignment of study infants was to demographically comparable intervention (Z) or control (FF) cohorts according to place of birth. In the intervention cohort (Z=564), the recommended dietary regimen was breastfeeding and – if exclusive breastfeeding was not possible – supplementation with a moderately hydrolysed, allergen-reduced infant formula (pHF). Weaning foods were delayed until four months of age or later in case of weaning foods with high allergenicity. In the control cohort (FF=566), there was no specific intervention. Imbalances between cohorts in confounding (adjuvant) factors that could influence health related outcomes were integrated as covariates into the logistic regression of the main analyses. Growth parameters included weight, length, head circumference, BMI, and Z scores (SDS). General health status was assessed by clinically significant findings in gastrointestinal, respiratory, or skin symptoms. Results. Growth at 6 weeks and at 3 and 6 months was similar for Z and FF. Significantly fewer Z than FF infants had clinically noteworthy health findings at 3 months (Z=27% versus FF=37%, odds ratio=0.63, CI=0.48–0.82) and 6 months (Z=33% versus FF=49%, odds ratio=0.51, CI=0.40–0.66). This corresponds to a 30% reduction in overall health concerns at 6 months for the intervention cohort. At 3 and 6 months, differences between cohorts in most measures of general health status were strongly influenced by a lower incidence of skin symptoms in the Z cohort. Within FF, there were fewer exclusively breastfed (eBF) infants with health problems at 3 months compared with those who were partially (pBF) or non-breastfed (nBF) (eBF=31%, pBF=40%, nBF=39%, p<0.05). In contrast, in the Z intervention cohort, the number of infants with health concerns was similar for exclusively breastfed infants and for those in whom mother's milk was supplemented or replaced by pHF (eBF=29%, pBF=25%, nBF=26%, ns). In a subanalysis of overall health findings in infants without a family risk of allergies, there were again significantly fewer Z than FF infants with any health or any skin problem. Conclusion.An allergen-reduced dietary recommendation that includes a moderate whey hydrolysate infant formula (pHF) has no negative effects on growth parameters up to 6 months of life in an infant population unselected for atopic risk. The dietary intervention produced improvements in general health status when compared with a control cohort that received infant formula with unhydrolysed proteins (IF), and high allergenic weaning foods at an earlier age. The difference between cohorts was principally due to fewer adverse skin findings. In infants following our allergen-reduced feeding recommendation, 3-month general health status was comparable between those who were exclusively breastfed and those in whom breastfeeding was supplemented or replaced by pHF. Our results demonstrate that a pHF feeding recommendation during the first 4 to 6 months of life – when exclusive breestfeeding is not possible – is a safe and feasible regimen not only in high-allergic risk populations but in general unselected infant population. The general use of pHF formula in non- or partly breastfed infants could therefore be considered an important contribution to optimised infant nutrition.

Addition of Supplementary Foods and Infant Growth (2 to 24 Months)

Objective: To determine the effect of adding supplementary foods on infant growth 2 to 8 and 12 to 24 months.

Methods: Length (cm/month) and weight (kg/month) of white infants (n = 94) were measured five to nine times from 2 to 24 months of age. Mothers reported birth weights, infants’ ages at first introduction of supplementary food, illnesses and information sources about infant feeding. Simple linear regression equations were used to compute slopes for each child (unit changes in length and in weight by age). Stepwise linear regression was used to determine the effect on weight and length slopes by the introduction of supplementary foods (e.g., an infant’s age when cereal, fruit, juice, vegetables and a meat cluster were first added) to the diet. Breast feeding (months duration or ever fed), illness scores and gender were covariates in the regression models.

Results: A significant model (F = 10.09, p = .002) for weight gain (2 to 8 months) showed that gender explained 10% of the variance; for length slope, the model was non-significant and gender explained 3% of the variance. Females had a slower weight gain compared to that of males. None of the covariates or supplementary foods were retained in the models. Weight prior to 12 months was the best predictor (p = .0001, 54% of the variance) of weight gain 12 to 24 months.

Conclusions: Unit changes in weight or length for an infant’s age were not statistically associated with the timing of when supplementary foods were first added to the diet 2 to 8 or 12 to 24 months. Weight prior to 12 months was a significant predictor of weight gain 12 to 24 months.     

Associations between Infant Feeding Practice Prior to Six Months and Body Mass Index at Six Years of Age

Rapid growth during infancy is associated with increased risk of overweight and obesity and differences in weight gain are at least partly explained by means of infant feeding. The aim was to assess the associations between infant feeding practice in early infancy and body mass index (BMI) at 6 years of age. Icelandic infants (n = 154) were prospectively followed from birth to 12 months and again at age 6 years. Birth weight and length were gathered from maternity wards, and healthcare centers provided the measurements made during infancy up to 18 months of age. Information on breastfeeding practices was documented 0–12 months and a 24-h dietary record was collected at 5 months. Changes in infant weight gain were calculated from birth to 18 months. Linear regression analyses were performed to examine associations between infant feeding practice at 5 months and body mass index (BMI) at 6 years. Infants who were formula-fed at 5 months of age grew faster, particularly between 2 and 6 months, compared to exclusively breastfed infants. At age 6 years, BMI was on average 1.1 kg/m² (95% CI 0.2, 2.0) higher among infants who were formula fed and also receiving solid foods at 5 months of age compared to those exclusively breastfed. In a high-income country such as Iceland, early introduction of solid foods seems to further increase the risk of high childhood BMI among formula fed infants compared with exclusively breastfed infants, although further studies with greater power are needed.     

Predictors of Breastfeeding Duration among Women in Kuwait: Results of a Prospective Cohort Study

The purposes of this paper are to report the prevalence of breastfeeding to six months among women in Kuwait and to determine the factors that are associated with the duration of breastfeeding. A cohort of 373 women recruited from maternity wards in four hospitals in Kuwait city were followed from birth to 26 weeks postpartum. The association of any and full breastfeeding duration and predictor variables were explored using multivariate Cox’s proportional hazards models. At six months, 39% of all infants were receiving some breast milk and only 2% of infants had been fully breastfed to 26 weeks. Women born in other Arab countries were less likely to discontinue breastfeeding than women born in Kuwait. Other factors positively associated with breastfeeding duration were level of maternal education, higher parity, infant being demand fed in hospital and a preference for breastfeeding on the part of the infant’s father and maternal grandmother. The introduction of a pacifier before four weeks of age and the mother intending to return to work by six months were negatively associated with duration. These findings present a number of opportunities for prolonging breastfeeding duration in Kuwait.     

Frequency of Sweet and Salty Snack Food Consumption Is Associated with Higher Intakes of Overconsumed Nutrients and Weight-For-Length z Scores During Infancy and Toddlerhood

BackgroundCurrent dietary guidelines recommend avoiding foods and beverages with added sugars and higher sodium before age 2 years.ObjectiveThe aim was to describe daily snack food intake (frequency and total energy) and the associations with overconsumed nutrients (added sugars, sodium, and saturated fats) and child weight-for-length z scores.DesignA cross-sectional, secondary analysis of baseline data from an ongoing longitudinal intervention was conducted.Participants and settingA sample of 141 caregivers with infants (aged 9 to 11 months) and toddlers (aged 12 to 15 months) was recruited in Buffalo, NY, between 2017 and 2019.Main outcome measuresThree 24-hour dietary recalls were used to categorize 'sweet and salty snack foods' or 'commercial baby snack foods' based on the US Department of Agriculture What We Eat in America food group classifications and estimate nutrient intakes. Child recumbent length and weight were measured by trained researchers.Statistical analysisDaily frequency (times/day), energy (kcal/day), and overconsumed nutrients from snack food intake were calculated. Multivariable regression models examined associations between the frequency of and energy from snack food intake with overconsumed nutrients and child weight-for-length z scores.ResultsInfants consumed snack foods on average 1.2 times/day contributing 5.6% of total daily energy, 19.6% of added sugars, and 6.8% of sodium. Toddlers consumed snack foods on average 1.4 times/day contributing 8.9% of total daily energy, 40.0% of added sugars, and 7.2% of sodium. In adjusted models including all children, greater frequency of sweet and salty snack food intake, but not commercial baby snack foods, was associated with higher weight-for-length z scores.ConclusionsSnack foods are frequently consumed by infants and toddlers and contribute to the intake of overconsumed nutrients such as added sugars and sodium. Given the current guidelines to avoid added sugars and higher sodium before age 2 years, additional recommendations related to nutrient-dense snack intake may be beneficial.     

A longitudinal study of breastfeeding and weaning practices during the first year of life in Dunedin,New Zealand

OBJECTIVE: To investigate infant feeding practices during the first year of life in a group of white infants in Dunedin, New Zealand. DESIGN: Prospective study of infants from birth to 12 months of age. PARTICIPANTS: A self-selected sample of 74 white mothers and their infants born in Dunedin, New Zealand, between October 1995 and May 1996. Statistical analyses Regression analyses were performed to determine factors associated with successful breastfeeding initiation and duration. RESULTS: Among mothers, 88% (n=65) initiated breastfeeding, 42% (n=31) were exclusively breastfeeding at 3 months, and 34% (n=25) were partially breastfeeding at 12 months. Intention to breastfeed increased the likelihood of successful breastfeeding initiation. Mothers who reported that they did not have enough breastmilk tended to exclusively breastfeed for a shorter period of time. Tertiary education and exclusively breastfeeding at 1 month were associated with a longer duration of breastfeeding. Perception of breastfeeding in public as embarrassing was associated with a shorter duration of breastfeeding. Among infants, 45% (n=33) were given nonmilk foods before 4 months of age, and 69% (n=51) were given unmodified cow's milk as a beverage before 12 months. APPLICATIONS: Breastfeeding rates in this study, although higher than in many Western countries, were still lower than current recommendations. Our findings suggest that women should be taught how to increase their breastmilk supply. Parents should also be informed of the importance of delaying the introduction of nonmilk foods until their infant is 4 to 6 months of age and cow's milk until they are 12 months of age. Society also needs to address the social issue of embarrassment many mothers feel when breastfeeding in public.     

Caregiver's Provision of Non-Recommended Commercially Prepared Milk-Based Drinks to Infants and Toddlers

ObjectiveAssess milk type provision (commercially prepared infant and toddler formula, cow's milk, and plant milk) to infants and toddlers, accounting for sociodemographic characteristics and marketing claims.ParticipantsCaregivers (N = 1,645) of children (aged 6–36 months) recruited through online panels in 2017.MethodsCross-sectional survey analysis (system of probit equations) estimated associations between sociodemographics and agreement with marketing claims (independent variables) with milk type provision in the past month (binary dependent variable).ResultsMost caregivers (63%) of infants (aged 6–11 months) provided only breastmilk and/or commercially prepared infant formula. Sixty-five percent of caregivers of 12-month-old infants provided commercially prepared infant formula, and 47% provided cow's milk. Most caregivers (64%) of toddlers (aged 13–36 months) provided cow's milk; some also provided other non-recommended milk types (51%).Associations between milk types suggested milk-based drink provision should be evaluated as a pattern and not as independent behaviors (all Ps < 0.048). Milk type provision was significantly associated with a child's age (months), household income, and race (all Ps < 0.049). Including agreement with marketing claims reduced the significance of associations between milk type provision and some sociodemographic characteristics.Conclusions and ImplicationsThese findings suggest the need for additional expert guidance to discourage inappropriate and unnecessary milk for young children, provide strategies to transition from breastmilk (or commercially prepared infant formula) to cow's milk, and conduct outreach to communities at risk for health disparities about the dangers of serving milk that is not recommended for their child's age. Research is needed to understand how diverse populations interpret product claims and how marketing may perpetuate health disparities.     

Breastfeeding and the introduction of solids in Australian infants: data from the 2001 National Health Survey

OBJECTIVE: To present estimates on rates of breastfeeding and timing of introduction of solid foods to Australian children, 1998-2001. METHODS: Analysis of data from the 2001 Australian National Health Survey (NHS) using lifetable methods. Infant feeding questions were asked by personal interview in respect to 1,883 children aged under three years of age. RESULTS: At discharge from hospital, 83.3% of infants were breastfeeding, which is similar to estimates from the 1995 NHS. At 13 weeks postpartum, 64.3% were breastfeeding, 49.0% at 25 weeks and 24.9% were continuing to breastfeed at one year. At 25 weeks, 18.4% of infants were fully breastfed. Solid food was being offered regularly to 15.2% of infants at 13 weeks and 88.0% by 26 weeks. CONCLUSION: Fewer than 50% of infants are receiving breast milk at six months, which is considerably lower than the 80% figure recommended by the latest Dietary Guidelines for Children and Adolescents. Very few Australian infants are being exclusively breastfed for the recommended six months. Infant feeding practices in Australia appear to have remained unchanged between 1995 and 2001.     

Breastfeeding patterns and energy adequacy

To analyze caloric adequacy in infant feeding six months of age or under, the volume of breast milk consumed was estimated through a regression equation as proposed by Drewett. Energy adequacy was estimated according to World Health Organization guidelines for developing countries and the recommended daily allowance of the Food and Nutrition Board. A cross-sectional analysis was conducted on data from a cohort of 118 infants in a neighborhood around a health center in Campinas, S?o Paulo, Brazil, with home interviews by trained students. Data were gathered on social and demographic characteristics, infant feeding patterns, duration of breastfeeding, frequency of feedings, and age when breast milk substitutes were introduced. On average, weaning began early, with a 2.7-month median duration of exclusive breastfeeding. Mean breast milk volume was estimated (from frequency of feeding) as 561.0 ml, 558.9 ml and 565.5 ml for children in exclusive, predominant, and supplemented breastfeeding, respectively. Mean energy consumption was adequate for all exclusively breastfed children regardless of age and above the recommended level for infants with supplemented breastfeeding and those already weaned.
