Item Household food insecurity, nutrient intakes and BMI in New Zealand infants(Cambridge University Press on behalf of The Nutrition Society, 2025-11-03) Katiforis I; Smith C; Haszard JJ; Styles SE; Leong C; Fleming EA; Taylor RW; Conlon CA; Beck KL; Von Hurst PR; Te Morenga LA; Daniels L; Rowan M; Casale M; McLean NH; Cox AM; Jones EA; Brown KJ; Bruckner BR; Jupiterwala R; Wei A; Heath A-LMObjective: The first year of life is a critical period when nutrient intakes can affect long-term health outcomes. Although household food insecurity may result in inadequate nutrient intakes or a higher risk of obesity, no studies have comprehensively assessed nutrient intakes of infants from food insecure households. This study aimed to investigate how infant nutrient intakes and body mass index (BMI) differ by household food security. Design: Cross-sectional analysis of the First Foods New Zealand study of infants aged 7–10 months. Two 24-hour diet recalls assessed nutrient intakes. “Usual” intakes were calculated using the Multiple Source Method. BMI z-scores were calculated using World Health Organization Child Growth Standards. Setting: Dunedin and Auckland, New Zealand. Participants: Households with infants (n=604) classified as: severely food insecure, moderately food insecure, or food secure. Results: Nutrient intakes of food insecure and food secure infants were similar, aside from slightly higher free and added sugars intakes in food insecure infants. Energy intakes were adequate, and intakes of most nutrients investigated were likely to be adequate. Severely food insecure infants had a higher mean BMI z-score than food secure infants, although no significant differences in weight categories (underweight; healthy weight; overweight) were observed between groups. Conclusions: Household food insecurity, in the short term, does not appear to adversely impact the nutrient intakes and weight status of infants. However, mothers may be protecting their infants from potential nutritional impacts of food insecurity. Future research should investigate how food insecurity affects nutrient intakes of the entire household.Item Parent-reported offering of allergen foods to infants during complementary feeding: An observational study of New Zealand infants(Elsevier Ltd, 2024-12-01) Medemblik JM; Conlon CA; Haszard JJ; Heath A-LM; Taylor RW; Von Hurst P; Beck KL; Te Morenga L; Daniels L; Keller KThe prevalence of food allergies in New Zealand infants is uncertain but is believed to be similar to Australia, exceeding 10%. Current recommendations for reducing food allergy risk are to offer all major food allergens to infants from as early as six months of age (start of complementary feeding), and before 12 months of age. However, little is known regarding parental practices around introducing major food allergens. This study aimed to explore parental offering of major food allergens to infants during complementary feeding, and parent-reported food allergies. The cross-sectional study is a secondary analysis of the multi-centre (Auckland and Dunedin) First Foods New Zealand study of 625 parent-infant dyads. Participants were recruited in 2020-2022 when infants were 7-10 months of age. Questionnaires assessed sociodemographic characteristics, complementary feeding approach, infant pouch use and parental responses to five food allergy questions. All major food allergens had been offered to only 17% of infants by 9-10 months of age. Having offered egg, peanut, tree nuts, sesame, soy and seafood was more commonly associated with using a baby-led complementary feeding approach than a parent-led approach (p < 0.001). Frequent baby food pouch use was associated with a lower likelihood of offering egg and peanut (both p < 0.001). Overall, 12.6% of infants had a reported food allergy, with symptomatic response after exposure being the most common diagnostic tool. Most infants are not offered all major food allergens during early complementary feeding, with some parents actively avoiding major food allergens in the first year of life. These results provide up-to-date knowledge of parental practices, highlighting the need for more targeted advice and strategies to improve parental engagement with allergy prevention and diagnosis.Item Frequent Use of Baby Food Pouches in Infants and Young Children and Associations with Energy Intake and BMI: An Observational Study.(MDPI (Basel, Switzerland), 2024-09-19) McLean NH; Bruckner BR; Heath A-LM; Haszard JJ; Daniels L; Conlon CA; von Hurst PR; Beck KL; Te Morenga LA; Firestone R; McArthur J; Paul R; Cox AM; Jones EA; Katiforis I; Brown KJ; Casale M; Jupiterwala RM; Rowan MM; Wei A; Fangupo LJ; Healey M; Pulu V; Neha T; Taylor RW; Fernandez M-LOBJECTIVE: Most wet commercial infant foods are now sold in squeezable 'pouches'. While multiple expert groups have expressed concern about their use, it is not known how commonly they are consumed and whether they impact energy intake or body mass index (BMI). The objectives were to describe pouch use, and determine associations with energy intake and BMI, in infants and young children. METHODS: In this observational cross-sectional study of 933 young New Zealand children (6.0 months-3.9 years), pouch use was assessed by a questionnaire ('frequent' use was consuming food from a baby food pouch ≥5 times/week in the past month), usual energy intake using two 24-h recalls, and BMI z-score calculated using World Health Organization standards. RESULTS: The sample broadly represented the wider population (27.1% high socioeconomic deprivation, 22.5% Māori). Frequent pouch use declined with age (infants 27%, toddlers 16%, preschoolers 8%). Few children were both frequent pouch users and regularly used the nozzle (infants 5%, toddlers 13%, preschoolers 8%). Preschoolers who were frequent pouch users consumed significantly less energy than non-users (-580 kJ [-1094, -67]), but infants (115 [-35, 265]) and toddlers (-206 [-789, 378]) did not appear to have a different energy intake than non-users. There were no statistically significant differences in the BMI z-score by pouch use. CONCLUSIONS: These results do not support the strong concerns expressed about their use, particularly given the lack of evidence for higher energy intake or BMI.Item Baby Food Pouches, Baby-Led Weaning, and Iron Status in New Zealand Infants: An Observational Study.(MDPI (Basel, Switzerland), 2024-05-15) McLean NH; Haszard JJ; Daniels L; Taylor RW; Wheeler BJ; Conlon CA; Beck KL; von Hurst PR; Te Morenga LA; McArthur J; Paul R; Katiforis I; Brown KJ; Gash MC; Rowan MM; Casale M; Cox AM; Jones EA; Jupiterwala RM; Bruckner B; Fleming L; Heath A-LM; Chen Y; Tran PV; Felt BTIron deficiency in infants can impact development, and there are concerns that the use of baby food pouches and baby-led weaning may impair iron status. First Foods New Zealand (FFNZ) was an observational study of 625 New Zealand infants aged 6.9 to 10.1 months. Feeding methods were defined based on parental reports of infant feeding at "around 6 months of age": "frequent" baby food pouch use (five+ times per week) and "full baby-led weaning" (the infant primarily self-feeds). Iron status was assessed using a venepuncture blood sample. The estimated prevalence of suboptimal iron status was 23%, but neither feeding method significantly predicted body iron concentrations nor the odds of iron sufficiency after controlling for potential confounding factors including infant formula intake. Adjusted ORs for iron sufficiency were 1.50 (95% CI: 0.67-3.39) for frequent pouch users compared to non-pouch users and 0.91 (95% CI: 0.45-1.87) for baby-led weaning compared to traditional spoon-feeding. Contrary to concerns, there was no evidence that baby food pouch use or baby-led weaning, as currently practiced in New Zealand, were associated with poorer iron status in this age group. However, notable levels of suboptimal iron status, regardless of the feeding method, emphasise the ongoing need for paying attention to infant iron nutrition.Item Baby food pouches and Baby-Led Weaning: Associations with energy intake, eating behaviour and infant weight status.(Elsevier B.V., 2024-01-01) Cox AM; Taylor RW; Haszard JJ; Beck KL; von Hurst PR; Conlon CA; Te Morenga LA; Daniels L; McArthur J; Paul R; McLean NH; Jones EA; Katiforis I; Brown KJ; Gash M; Rowan M; Fleming EA; Jupiterwala R; Bruckner BR; Heath A-LMAlthough concern is frequently expressed regarding the potential impact of baby food pouch use and Baby-Led Weaning (BLW) on infant health, research is scarce. Data on pouch use, BLW, energy intake, eating behaviour and body mass index (BMI) were obtained for 625 infants aged 7-10 months in the First Foods New Zealand study. Frequent pouch use was defined as ≥5 times/week during the past month. Traditional spoon-feeding (TSF), "partial" BLW and "full" BLW referred to the relative proportions of spoon-feeding versus infant self-feeding, assessed at 6 months (retrospectively) and current age. Daily energy intake was determined using two 24-h dietary recalls, and caregivers reported on a variety of eating behaviours. Researchers measured infant length and weight, and BMI z-scores were calculated (World Health Organization Child Growth Standards). In total, 28% of infants consumed food from pouches frequently. Frequent pouch use was not significantly related to BMI z-score (mean difference, 0.09; 95% CI -0.09, 0.27) or energy intake (92 kJ/day; -19, 202), but was associated with greater food responsiveness (standardised mean difference, 0.3; 95% CI 0.1, 0.4), food fussiness (0.3; 0.1, 0.4) and selective/restrictive eating (0.3; 0.2, 0.5). Compared to TSF, full BLW was associated with greater daily energy intake (BLW at 6 months: mean difference 150 kJ/day; 95% CI 4, 297; BLW at current age: 180 kJ/day; 62, 299) and with a range of eating behaviours, including greater satiety responsiveness, but not BMI z-score (6 months: 0.06 (-0.18, 0.30); current age: 0.06 (-0.13, 0.26)). In conclusion, neither feeding approach was associated with weight in infants, despite BLW being associated with greater energy intake compared with TSF. However, infants who consumed pouches frequently displayed higher food fussiness and more selective eating.Item Adherence to Infant Feeding Guidelines in the First Foods New Zealand Study.(MDPI (Basel, Switzerland), 2023-11-02) Brown KJ; Beck KL; Von Hurst P; Heath A-L; Taylor R; Haszard J; Daniels L; Te Morenga L; McArthur J; Paul R; Jones E; Katiforis I; Rowan M; Casale M; McLean N; Cox A; Fleming E; Bruckner B; Jupiterwala R; Wei A; Conlon C; Rodríguez Martínez GInfant feeding guidelines provide evidence-based recommendations to support optimal infant health, growth, and development, and exploring adherence to guidelines is a useful way of assessing diet quality. The aim of this study was to determine adherence to the recently updated Ministry of Health "Healthy Eating Guidelines for New Zealand Babies and Toddlers (0-2 years old)". Data were obtained from First Foods New Zealand, a multicentre observational study of 625 infants aged 7.0-10.0 months. Caregivers completed two 24-h diet recalls and a demographic and feeding questionnaire. Nearly all caregivers (97.9%) initiated breastfeeding, 37.8% exclusively breastfed to around six months of age, and 66.2% were currently breastfeeding (mean age 8.4 months). Most caregivers met recommendations for solid food introduction, including appropriate age (75.4%), iron-rich foods (88.3%), puréed textures (80.3%), and spoon-feeding (74.1%). Infants consumed vegetables (63.2%) and fruit (53.9%) more frequently than grain foods (49.5%), milk and milk products (38.6%), and meat and protein-rich foods (31.8%). Most caregivers avoided inappropriate beverages (93.9%) and adding salt (76.5%) and sugar (90.6%). Our findings indicated that while most infants met the recommendations for the introduction of appropriate solid foods, the prevalence of exclusive breastfeeding could be improved, indicating that New Zealand families may need more support.
