Family and infant characteristics associated with timing of core and non-core food introduction in early childhood

Socioeconomic Characteristics and the Home Food Environment Are Associated With Feeding Healthful and Discretionary Foods During the First Year of Life in the Pregnancy Eating Attributes Study

BACKGROUND

Feeding of nutrient-poor foods begins in infancy and may adversely influence long-term food preferences.

OBJECTIVE

To examine associations of socioeconomic characteristics, childbearing parent eating behaviors, and home food environment with infant feeding characteristics.

DESIGN

Secondary analysis of a prospective cohort study from first trimester of pregnancy through 12 months postpartum.

PARTICIPANTS/SETTING

Participants with uncomplicated singleton pregnancies and no major chronic illness were enrolled from November 2014 through October 2016 from 2 university-based obstetrics clinics in Chapel Hill, NC. Of 458 enrolled, 321 were retained through 12 months postpartum.

MAIN OUTCOME MEASURES

Participants completed infant food frequency questionnaires indicating age at introduction and frequency of consuming multiple food groups. Exposures included childbearing parent socioeconomic characteristics, hedonic hunger, addictive-like eating, Healthy Eating Index 2015 calculated from three 24-hour diet recalls, and home food environment fruit/vegetable and obesogenic scores.

STATISTICAL ANALYSES PERFORMED

Multiple imputation using Heckman selection model; linear and logistic regressions examining associations with infant feeding characteristics.

RESULTS

Lower education and income were associated with later infant age at introduction to, and lower frequency of consuming fruits and vegetables at age 12 months. Socioeconomic characteristics were not associated with age at introduction to discretionary solid foods; however, lower education and income were associated with greater infant frequency of intake of discretionary foods and greater odds of introducing fruit juice and sweetened beverages by age 12 months. Childbearing parent Healthy Eating Index 2015, hedonic hunger, and addictive-like eating were not consistently associated with infant feeding characteristics. A more obesogenic food environment was associated with greater frequency of intake of discretionary foods, lower frequency of intake of fruit, and greater odds of fruit juice introduction by age 12 months.

CONCLUSIONS

Infant feeding characteristics may be important intervention targets for addressing socioeconomic disparities in child diet quality. Efforts to reduce routine feeding of discretionary foods across socioeconomic groups are needed; modifying the home food environment may promote healthful infant feeding.

Prevalence and maternal determinants of early and late introduction of complementary foods: results from the Growing Up in New Zealand cohort study

A nationally generalisable cohort (n 5770) was used to determine the prevalence of non-timely (early/late) introduction of complementary food and core food groups and associations with maternal sociodemographic and health behaviours in New Zealand (NZ). Variables describing maternal characteristics and infant food introduction were sourced, respectively, from interviews completed antenatally and during late infancy. The NZ Infant Feeding Guidelines were used to define early (≤ 4 months) and late (≥ 7 months) introduction. Associations were examined using multivariable multinomial regression, presented as adjusted relative risk ratios and 95 % confidence intervals (RRR; 95% CI). Complementary food introduction was early for 40·2 % and late for 3·2 %. The prevalence of early food group introduction were fruit/vegetables (23·8 %), breads/cereals (36·3 %), iron-rich foods (34·1 %) and of late were meat/meat alternatives (45·9 %), dairy products (46·2 %) and fruits/vegetables (9·9 %). Compared with infants with timely food introduction, risk of early food introduction was increased for infants: breastfed < 6months (2·52; 2·19-2·90), whose mothers were < 30 years old (1·69; 1·46-1·94), had a diploma/trade certificate v. tertiary education (1·39; 1·1-1·70), of Māori v. European ethnicity (1·40; 1·12-1·75) or smoked during pregnancy (1·88; 1·44-2·46). Risk of late food introduction decreased for infants breastfed < 6 months (0·47; 0.27-0·80) and increased for infants whose mothers had secondary v. tertiary education (2·04; 1·16-3·60) were of Asian v. European ethnicity (2·22; 1·35, 3·63) or did not attend childbirth preparation classes (2·23; 1·24-4·01). Non-timely food introduction, specifically early food introduction, is prevalent in NZ. Interventions to improve food introduction timeliness should be ethnic-specific and support longer breast-feeding.

Correlates of Sub-Optimal Feeding Practices among under-5 Children amid Escalating Crises in Lebanon: A National Representative Cross-Sectional Study

Sub-optimal feeding practices among under-5 children are the major drivers of malnutrition. This study aims to assess the prevalence of malnutrition and the factors affecting exclusive breastfeeding, bottle feeding, and complementary feeding practices among under 5 children amid the COVID-19 pandemic as well as the economic and the political crises in Lebanon. A nationally representative stratified random sample of mother-child dyads (n = 511) was collected from households using a stratified cluster sampling design. The survey inquired about infant's feeding and complementary feeding practices using a valid questionnaire. Anthropometric measurements of the mother and child were collected. Multivariate logistic regression was conducted to explore the determinants associated with under-5 children's practices. The prevalence of underweight, stunting, wasting, overweight and obese children was 0.5%, 8.4%, 6.7%, 16.8% and 8.9%, respectively. In total, among under-5 children, the prevalence of ever breastfeeding, exclusive breastfeeding, and bottle feeding at birth was 95.1%, 59.1% and 25.8%, respectively. Half the children in this study started solid foods between 4 and 6 months. Regression analysis showed that supporting breastfeeding at hospital (aOR = 8.20, 95% CI (3.03-22.17)) and husband's support (aOR = 3.07, 95% CI (1.9-4.92)) were associated with increased breastfeeding odds. However, mother's occupation (aOR = 0.18, 95% CI (0.55-0.58)) was inversely associated with breastfeeding practices. Male children (aOR = 2.119, 95% CI (1.37-3.27), mothers diagnosed with COVID-19 (aOR = 0.58, 95% CI (0.35-0.95)), and bottle feeding at hospital (aOR = 0.5, 95% CI (0.32-0.77)) were more likely to induce early initiation of solid foods at 4 months of age. This study demonstrated non-negligible rates of malnutrition, low prevalence of exclusive breastfeeding, and high rates of early introduction of formula feeding and solid foods among Lebanese under-5-children amid escalating crises.

Factors Influencing the Early Introduction of Sugar Sweetened Beverages among Infants: Findings from the HSHK Birth Cohort Study

Understanding the determinants of early introduction of sugar sweetened beverages (SSBs) may assist in designing effective public health interventions to prevent childhood weight related conditions (obesity). This study explores the relationship between family/infant characteristics and the early introduction of SSBs among infants in Sydney, Australia. Mothers (n = 934) from an ongoing birth cohort study were interviewed at 8, 17, 34, and 52 weeks postpartum. Multivariable logistic regression analysis was used to identify family/infant factors independently associated with the likelihood of early introduction of SSBs (<52 weeks of age). Of the 934 mothers interviewed, 42.7% (n = 399) of infants were introduced to SSBs before 52 weeks. Mothers who were born in Vietnam (adjusted Odds Ratio (AOR) = 2.14; 95% confidence interval (CI) 1.33, 3.47), other Asian countries (AOR = 1.62; 95% CI 1.02, 2.58) as well as single mothers (AOR = 3.72; 95% CI 2.46, 5.62) had higher odds of introducing SSBs early to their infants. Mothers from highly advantaged socioeconomic background (AOR = 0.43; 95% CI 0.28, 0.68), those who breastfed their baby for 17–25 weeks (AOR = 0.60; 95% CI 0.37, 0.99), 26–51 weeks (AOR = 0.65; 95% CI 0.45, 0.94), and 52 weeks or more (AOR = 0.62; 95% CI 0.43, 0.90); and those who introduced solids between 17–25 weeks (AOR = 0.58; 95% CI 0.36, 0.91) and 26 weeks or more (AOR = 0.55; 95% CI 0.34, 0.91) had reduced odds of introducing SSBs early. Tailoring health promotion programs for these vulnerable groups may delay the introduction of SSBs.

Introduction to complementary feeding in the first year of life and risk of overweight at 24 months of age: changes from 2004 to 2015 Pelotas (Brazil) Birth Cohorts

Complementary feeding (CF) and overweight relationships during early childhood are inconsistent in the literature. We described the association of CF during the first year of life with risk of overweight at 24 months of age in the population-based 2004 and 2015 Pelotas (Brazil) Birth Cohorts (2004c and 2015c). CF introduction was evaluated at the 3 and 12 months' follow-ups by asking mothers using a list of foods. Risk of overweight at 24 months of age was BMI-for-age z-score above +1sd from the median of the WHO 2006 growth standards. Our analyses included 3823 (2004c) and 3689 (2015c) children. Early introduction CF (before 6 months of age) prevalence in 2004c was 93·3 (95 % CI 92·5, 94·1) % and in 2015c was 87·2 (95 % CI 86·1, 88·2) %. Tea was the item introduced earlier in both 2004c (68·8 %) and 2015c (55·7 %). At 6 months of age, vegetable mash was the most introduced food in 2004c (33·5 %) and 2015c (47·9 %). Between 2004c and 2015c, the introduction of fresh milk decreased 82·1 to 60·5 % and yogurt from 94·4 to 78·1 % during the first year. Risk of overweight prevalence at 24 months was 33·0 (95 % CI 31·6, 34·5) % in 2004c and 32·0 (95 % CI 30·5, 33·5) % in 2015c. In 2015c, the adjusted odds of risk of overweight at 24 months were increased 1·66 and 1·50 times with the early introduction of fresh/powdered milk: plus water, tea or juice, and plus semi-solid/solid food groups, respectively. It is essential to reinforce the adherence to global recommendations on timely feeding introduction and encourage exclusive breast-feeding until 6 months of age to prevent child overweight.

Predictors of Early Introduction of Core and Discretionary Foods in Australian Infants-Results from HSHK Birth Cohort Study

Early introduction of complementary foods can have a detrimental impact on children's long-term health. This study examined the timing and determinants of early introduction of core and discretionary foods among infants in Sydney, Australia. Mothers (n = 1035) from an ongoing population-based birth cohort study were interviewed at 8, 17, 34 and 52 weeks postpartum. The outcome was 'age at which particular core and discretionary food items were first introduced'. Multivariable logistic regression models were used to investigate family and infant-related determinants of early introduction of core (<17 weeks of age) and discretionary foods (<52 weeks of age). Of the 934 mother-infant dyads interviewed, 12% (n = 113) of infants were introduced core foods before 17 weeks of age (median: 22). Mothers working part-time (adjusted odds ratio (OR): 3.42, 95% confidence interval (CI): 1.54-7.62) and those exclusively formula-feeding their babies at four-weeks postpartum (adjusted OR 3.26, 95% CI: 1.99-5.33) were most likely to introduce core foods early. Ninety-five percent (n = 858) of infants were introduced discretionary foods before 52 weeks of age (median: 28). Low socio-economic status was significantly associated with early introduction of discretionary foods (adjusted OR: 3.72, 95% CI: 1.17-11.78). Compliance with infant feeding guidelines related to core foods was better; however, discretionary foods were introduced early in most infants.

Family Eating Behavior and Child Eating Patterns Differences Between Children With and Without Siblings

OBJECTIVE

To examine the differences in family eating behaviors and child eating patterns in children with siblings (nonsingletons) and without siblings (singletons).

METHODS

Cross-sectional analysis of mother-child dyads of 5-7-year-old children, (nonsingletons with a 2-to-4-year-old sibling) was conducted. Anthropometrics were measured. Mothers completed questionnaires and a child dietary log. Healthy Eating Index 2010 (HEI) score was calculated. Linear regression models adjusting for child age, child sex, maternal body mass index, and hours-away-from-home were conducted, with a revised P < .021.

RESULTS

Sixty-eight mother-child dyads (27 singletons, 41 nonsingletons) participated. Singletons exhibited less healthy family eating behaviors (β = -4.98, SE = 1.88, P = .003), and lower total HEI scores than did nonsingletons (average: β = -8.91, SE =2.40, P = .001). On average, singletons had lower scores in 3 HEI components compared with nonsingletons (P < .021 for all).

CONCLUSION

In this sample, singleton children exhibited less healthy eating behaviors. Additional investigation into parent-level differences is warranted.

Difference in Objectively Measured Physical Activity and Obesity in Children With and Without Siblings

Background/Context: Children without siblings (singletons) have higher rates of obesity than do children with siblings (nonsingletons). Higher moderate to vigorous physical activity (PA) and less sedentary behavior (SB) are associated with lower childhood obesity.

PURPOSE

To examine the difference in PA and SB between singleton and nonsingleton children.

METHODS

Mothers of children ages 5.0-7.9 years old who were singletons or nonsingletons with a sibling between the ages of 2.0 and 4.9 years old were recruited. Height, weight, and waist circumference of the 5.0- to 7.9-year-old children were measured, and age and sex percentiles were calculated. Accelerometry measured SB and PA, including light PA, moderate to vigorous PA, and counts per minute.

RESULTS

Fifty-six mother-child dyads (23 singletons and 33 nonsingletons) with an average child age of 5.7 (0.7) years participated. More singletons were classified as overweight or obese than were nonsingletons (49% vs 17%, P = .04). In adjusted linear models, singletons had less light PA per day (β = -38.1, SE = 19.2, P = .001) and more SB (β = 38.0, SE = 16.5, P = .02) than did nonsingletons, with no difference in moderate to vigorous PA or counts per minute.

CONCLUSION

In this sample, singletons had higher obesity and lower light PA than did nonsingleton children. Investigation into differences in singleton/nonsingleton families, including family health behaviors, may help assess sibling influence in early behavior development.

Factors associated with early introduction of complementary feeding and consumption of non-recommended foods among Dutch infants: the BeeBOFT study

BACKGROUND

Timing and types of complementary feeding in infancy affect nutritional status and health later in life. The present study aimed to investigate the factors associated with early introduction of complementary feeding (i.e., before age 4 months), and factors associated with infants consumption of non-recommended foods, including sweet beverages and snack foods.

METHODS

This study used cross-sectional data from the BeeBOFT study (n = 2157). Data on complementary feeding practices and potential determinants were obtained by questionnaire at infant's age of 6 months. Logistic regression models were used to investigate factors associated with early introduction of complementary feeding and infants' consumption of non-recommended foods.

RESULTS

21.4% of infants had received complementary feeding before 4 months of age. At the age of 6 months, 20.2% of all infants were consuming sweet beverages daily and 16.5% were consuming snack foods daily. Younger maternal age, lower maternal educational level, absence or shorter duration of breastfeeding, parental conviction that "my child always wants to eat when he/she sees someone eating" and not attending day-care were independently associated with both early introduction of complementary feeding and the consumption of non-recommended foods. Higher maternal pre-pregnancy BMI and infant postnatal weight gain were associated only with early introduction of complementary feeding.

CONCLUSIONS

We identified several demographical, biological, behavioral, psychosocial, and social factors associated with inappropriate complementary feeding practices. These findings are relevant for designing intervention programs aimed at educating parents.

Timing of complementary feeding and associations with maternal and infant characteristics: A Norwegian cross-sectional study

Norwegian Health authorities recommend solid food to be introduced between child age 4-6 months, depending on both the mother´s and infant's needs. The aim of this paper is to describe timing of complementary feeding in a current sample of Norwegian mother/infant-dyads and explore potential associations between timing of introduction to solid foods and a wide range of maternal and infant characteristics known from previous literature to influence early feeding interactions. The paper is based on data from the Norwegian randomized controlled trial Early Food for Future Health. In 2016, a total of 715 mothers completed a web-based questionnaire at child age 5.5 months. We found that 5% of the infants were introduced to solid food before 4 months of age, while 14% were not introduced to solid food at 5.5 months of age. Introduction of solid food before 4 months of age was associated with the infant not being exclusive breastfed the first month, receiving only formula milk at 3 months, the mother being younger, not married/cohabitant, smoking, less educated and having more economic difficulties. Not being introduced to solid food at 5.5 months was associated with the infant being a girl, being exclusive breastfed the first month, receiving only breastmilk at 3 months, the mother being older, married and having 3 or more children. This study shows that there are still clear socioeconomic differences regarding timing of complementary feeding in Norway. Infants of younger, less educated and smoking mothers are at higher risk of not being fed in compliance with the official infant feeding recommendations. Our findings emphasize the importance of targeting socioeconomically disadvantaged mothers for support on healthy feeding practices focusing on the infant`s needs to prevent early onset of social inequalities in health.

Maternal and infant factors associated with reasons for introducing solid foods

The current UK Department of Health advice is to introduce solid foods to infants at around 6 months of age, when the infant is showing signs of developmental readiness for solid foods. However, many mothers introduce solid foods before this time, and for a wide variety of reasons, some of which may not promote healthy outcomes. The aim of the current study was to examine infant and maternal characteristics associated with different reasons for introducing solid foods. Seven hundred fifty-six mothers with an infant aged 6-12 months old completed a questionnaire describing their main reason for introducing solid foods alongside demographic questions, infant weight, gender, breast/formula feeding and timing of introduction to solid foods. The majority of mothers introduced solid foods for reasons explicitly stated in the Department of Health advice as not signs of readiness for solid foods. These reasons centred on perceived infant lack of sleep, hunger or unsettled behaviour. Maternal age, education and parity, infant weight and gender and breast/formula feeding choices were all associated with reasons for introduction. A particular association was found between breastfeeding and perceiving the infant to be hungrier or needing more than milk could offer. Male infants were perceived as hungry and needing more energy than female infants. Notably, signs of readiness may be misinterpreted with some stating this reason for infants weaned prior to 16 weeks. The findings are important for those working to support and educate new parents with the introduction of solid foods in understanding the factors that might influence them.

Maternal weight status, diet, and supplement use as determinants of breastfeeding and complementary feeding: a systematic review and meta-analysis

CONTEXT

Infant feeding practices are influenced by maternal factors.

OBJECTIVE

The aim of this review is to examine the associations between maternal weight status or dietary characteristics and breastfeeding or complementary feeding.

DATA SOURCES

A systematic literature search of the Embase, Cochrane Library, Google Scholar, MEDLINE, PubMed, and Web of Science databases was performed.

STUDY SELECTION

Interventional and cohort studies in healthy mothers and infants that reported on maternal weight status, diet, or supplement use were selected.

DATA EXTRACTION

Outcomes assessed included delayed onset of lactogenesis; initiation, exclusivity, duration, and cessation of breastfeeding; and timing of complementary feeding.

DATA ANALYSIS

Eighty-one studies were included. Maternal underweight, diet, and supplement use were not associated with infant feeding practices. Obese women had a relative risk of failure to initiate breastfeeding (risk ratio [RR] = 1.23; 95%CI, 1.03-1.47) and a delayed onset of lactogenesis (RR  =  2.06; 95%CI, 1.18-3.61). The RR for breastfeeding cessation was 1.11 (95%CI, 1.07-1.15) per increase in category of body mass index.

CONCLUSIONS

Prevention of obesity in women of reproductive age, as well as counseling of obese women after delivery, could be targeted to improve infant feeding practices.

Obesogenic dietary intake in families with 1-year-old infants at high and low obesity risk based on parental weight status: baseline data from a longitudinal intervention (Early STOPP)

Purpose

To compare dietary intake in 1-year-old infants and their parents between families with high and low obesity risk, and to explore associations between infant dietary intake and relative weight.

Methods

Baseline analyses of 1-year-old infants (n = 193) and their parents participating in a longitudinal obesity intervention (Early STOPP) were carried out. Dietary intake and diet quality indicators were compared between high- and low-risk families, where obesity risk was based on parental weight status. The odds for high diet quality in relation to parental diet quality were determined. Associations between measured infant relative weight and dietary intake were examined adjusting for obesity risk, socio-demographics, and infant feeding.

Results

Infant dietary intake did not differ between high- and low-risk families. The parents in high-risk families consumed soft drinks, French fries, and low-fat spread more frequently, and fish and fruits less frequently (p < 0.05) compared to parents in low-risk families. Paternal intake of vegetables and fish increased the odds for children being consumers of vegetables (OR 1.7; 95 % CI 1.0–2.9) and fish, respectively (OR 2.5; 95 % CI 1.4–4.4). Infant relative weight was weakly associated with a high intake of milk cereal drink (r = 0.15; p < 0.05), but not with any other aspect of dietary intake, obesity risk, or early feeding patterns.

Conclusions

At the age of one, dietary intake in infants is not associated with family obesity risk, nor with parental obesogenic food intake. Milk cereal drink consumption but no other infant dietary marker reflects relative weight at this young age.

Infant feeding knowledge, attitudes, and beliefs predict antenatal intention among first-time mothers in Queensland

AIM

This study assessed infant feeding knowledge, attitudes, and beliefs among women from Queensland, Australia, in their first pregnancy. Antenatal feeding intention in this group was described, and the hypothesis was tested that antenatal knowledge, attitudes, and beliefs about infant feeding are associated with antenatal intention for the duration and exclusivity of breastfeeding for the infant's first year.

SUBJECTS AND METHODS

The Feeding Queensland Babies Study is a prospective survey of infant feeding attitudes and behaviors among first-time mothers in Queensland, Australia. Data on infant feeding knowledge, attitudes, beliefs, and intention were collected antenatally, and an Infant Feeding Attitudes Score was calculated.

RESULTS

Although 85% of respondents endorsed breastfeeding as most appropriate for infants, 11% valued formula feeding equally. Intention to give any breastmilk during the first weeks was 98%, but it fell to 18% during the second year. More than one-quarter of women reported intention to introduce foods other than breastmilk before 5 months of infant age. The infant feeding attitudes and beliefs score correlated positively with feeding intention for breastfeeding and the introduction of complementary solids.

CONCLUSIONS

Enhancing women's knowledge of recommendations and their understanding of breastfeeding's specific benefits and the reasons for recommended scheduling of feeding transitions may positively impact breastfeeding exclusivity and duration and the age-appropriate introduction of complementary solids. Communication of detailed feeding recommendations for the infant's first year and specific information about the health benefits of breastfeeding should be a goal of healthcare providers working with pregnant women.

Complementary feeding and obesity risk

PURPOSE OF REVIEW

This article will summarize recent progress in research in the area of complementary feeding as it relates to childhood obesity. Newly emerged findings demonstrate how research on contributing factors has shifted. Examining nutrient and caloric intakes alone has failed to answer the critical question, 'Why are some children obese, whereas others are not?' Recent research explores parental attitudes, beliefs and parental feeding styles as contributing factors.

RECENT FINDINGS

Studies examining the impact of specific macronutrients on obesity risk may have partially uncovered a link between consistently high protein intakes during infancy and an elevated obesity risk, at least until the second year of life. However, this relationship was not evident in all studies evaluated in a systematic review this year. Childhood obesity is not linked to any specific types of foods or food groups during the complementary feeding period. Adherence to dietary guidelines is associated with increased lean body mass, but not BMI or fat mass. Complementary feeding practices, socioeconomic and other family dynamics at least partially explain obesity risk.

SUMMARY

As young infants are dependent on adults for nourishment, parental attitudes and beliefs about infant nutrition and actual feeding practices directly influence infant nutritional status. Early nutrition interventions to prevent obesity should take nutrition belief systems, parental feeding styles, socioeconomic and educational status, among other characteristics into consideration.
