Summary: Background: Data on body mass index (BMI) in infants and toddlers worldwide are lacking, relative to older age groups. Objectives: To describe the growth (weight, length/height, head circumference, and BMI z‐score) of New Zealand children under the age of 3 years, and examine differences by sociodemographic characteristics (sex, ethnicity, and deprivation). Methods: Electronic health data were collected by Whānau Āwhina Plunket, who provide free 'Well Child' services for approximately 85% of newborn babies in New Zealand. Data from children under the age of 3, who had their weight and length/height measured between 2017 and 2019, were included. The prevalence of BMI (WHO child growth standards) ≤2nd, ≥85th, and ≥95th percentiles were determined. Results: Between 12 weeks and 27 months of age, the percentage of infants ≥85th BMI percentile increased from 10.8% (95% CI, 10.4%–11.2%) to 35.0% (34.2%–35.9%). The percentage of infants with high BMI (≥95th percentile) also increased, particularly between 6 months (6.4%; 95% CI, 6.0%–6.7%) and 27 months (16.4%; 15.8%–17.1%). By contrast, the percentage of infants with low BMI (≤2nd percentile) appeared steady between 6 weeks and 6 months, and declined at older ages. The prevalence of infants with a high BMI appears to increase substantially from 6 months across sociodemographic characteristics, with a widening prevalence gap by ethnicity occurring from 6 months, mirroring that of infants with a low BMI. Conclusions: The number of children with high BMI increases rapidly between 6 months and 27 months of age, suggesting this is an important timeframe for monitoring and preventive action. Future work should investigate the longitudinal growth trajectories of these children to determine if any particular patterns predict later obesity and what strategies could effectively change them.

Background: A recent paradigm shift has highlighted the importance of considering how sleep, physical activity and sedentary behaviour work together to influence health, rather than examining each behaviour individually. We aimed to determine how adherence to 24-h movement behavior guidelines from infancy to the preschool years influences mental health and self-regulation at 5 years of age. Methods: Twenty-four hour movement behaviors were measured by 7-day actigraphy (physical activity, sleep) or questionnaires (screen time) in 528 children at 1, 2, 3.5, and 5 years of age and compared to mental health (anxiety, depression), adaptive skills (resilience), self-regulation (attentional problems, hyperactivity, emotional self-control, executive functioning), and inhibitory control (Statue, Head-Toes-Knees-Shoulders task) outcomes at 5 years of age. Adjusted standardised mean differences (95% CI) were determined between those who did and did not achieve guidelines at each age. Results: Children who met physical activity guidelines at 1 year of age (38.7%) had lower depression (mean difference [MD]: -0.28; 95% CI: -0.51, -0.06) and anxiety (MD: -0.23; 95% CI: -0.47, 0.00) scores than those who did not. At the same age, sleeping for 11–14 h or having consistent wake and sleep times was associated with lower anxiety (MD: -0.34; 95% CI: -0.66, -0.02) and higher resilience (MD: 0.35; 95% CI: 0.03, 0.68) scores respectively. No significant relationships were observed at any other age or for any measure of self-regulation. Children who consistently met screen time guidelines had lower anxiety (MD: -0.43; 95% CI: -0.68, -0.18) and depression (MD: -0.36; 95% CI: -0.62, -0.09) scores at 5. However, few significant relationships were observed for adherence to all three guidelines; anxiety scores were lower (MD: -0.42; 95% CI: -0.72, -0.12) in the 20.2% who adhered at 1 year of age, and depression scores were lower (MD: -0.25; 95% CI: -0.48, -0.02) in the 36.7% who adhered at 5 years of age compared with children who did not meet all three guidelines. Conclusions: Although adherence to some individual movement guidelines at certain ages throughout early childhood was associated with improved mental health and wellbeing at 5 years of age, particularly reduced anxiety and depression scores, there was little consistency in these relationships. Future work should consider a compositional approach to 24-h time use and how it may influence mental wellbeing. Trial registration: ClinicalTrials.gov number NCT00892983 [ABSTRACT FROM AUTHOR]

Background Gut microbiota data obtained by DNA sequencing are complex and compositional because of large numbers of detectable taxa, and because microbiota characteristics are described in relative terms. Nutrition researchers use principal component analysis (PCA) to derive dietary patterns from food data. Although compositional PCA methods are not commonly used to describe patterns from complex microbiota data, this approach would be useful for identifying gut microbiota patterns associated with diet and body composition. Objectives To use compositional PCA to describe the principal components (PCs) of gut microbiota in 5-y-old children and explore associations between microbiota components, diet, and BMI z -score. Methods A fecal sample was provided by 319 children aged 5 y. Their primary caregiver completed a validated 123-item quantitative FFQ. Body composition was determined using DXA, and a BMI z -score was calculated. Compositional PCA identified characterizing taxa and weightings for calculation of gut microbiota PC scores at the genus level, and was examined in relation to diet and body size. Results Three gut microbiota PCs were found. PC1 (negative loadings on uncultured Christensenellaceae and Ruminococcaceae) was related to lower BMI z -scores and longer duration of breastfeeding (per month) (β = −0.14; 95% CI: −0.26, −0.02; and β = 0.02; 95% CI: 0.003, 0.34, respectively). PC2 (positive loadings on Fusicatenibacter and Bifidobacterium ; negative loadings on Bacteroides) was associated with a lower intake of nuts, seeds, and legumes (β = −0.05 per gram; 95% CI: −0.09, −0.01). When adjusted for fiber intake, PC2 was also associated with higher BMI z -scores (β = 0.12; 95% CI: 0.01, 0.24). PC3 (positive loadings on Faecalibacterium, Eubacterium , and Roseburia) was associated with higher intakes of fiber (β = 0.02 per gram; 95% CI: 0.003, 0.04) and total nonstarch polysaccharides (β = 0.02 per gram; 95% CI: 0.003, 0.04). Conclusions Our results suggest that specific gut microbiota components determined using compositional PCA are associated with diet and BMI z -score. This trial was registered at clinicaltrials.gov as NCT00892983. [ABSTRACT FROM AUTHOR]

Objectives: Despite the American Academy of Pediatrics (AAP) recommending that electronic media be avoided in children under two years of age, screen use is common in infants and toddlers. The aims of this study were to determine how parenting style, infant temperament, and family type are associated with television viewing in two-year-old children. Study design: Participants were from the Prevention of Overweight in Infancy (POI) randomized controlled trial (n = 802) (Dunedin, New Zealand). Demographic information was collected at baseline (late pregnancy), and television and other screen time assessed by questionnaire at 24 months of age. Parenting style (Parenting Practices Questionnaire), infant temperament (Colorado Childhood Temperament Inventory), and family type (7 categories) were reported by both parents. Results: Data were available for 487 participants (61% of the original participants). Median television viewing was relatively low at 21 minutes per day, or 30 minutes in those watching television (82%). Children who watched television played with mobile phones (12% of children) or iPads/tablets (22% of children) more frequently than children who did not (6% of children). In terms of parenting style, children of more authoritarian mothers (β = 17, 95% CI: 6–27 minutes), more authoritarian partners (β = 14, 95% CI: 2–26 minutes), or more permissive mothers (β = 10, 95% CI: 3–17 minutes) watched significantly more television. No significant relationships were observed between child temperament and time watching television after adjustment for confounding variables. Children from “active” families (as rated by partners) watched 29 minutes less television each day (P = 0.002). Conclusions: Parenting style and family type were associated with television viewing time in young children, whereas child temperament was not. [ABSTRACT FROM AUTHOR]

OBJECTIVE: The few existing early-life obesity prevention initiatives have concentrated on nutrition and physical activity, with little examination of sleep. METHODS: This community-based, randomized controlled trial allocated 802 pregnant women (≥16 years, <34 weeks' gestation) to: control, FAB (food, activity, and breastfeeding), sleep, or combination (both interventions) groups. All groups received standard well-child care. FAB participants received additional support (8 contacts) promoting breastfeeding, healthy eating, and physical activity (antenatal-18 months). Sleep participants received 2 sessions (antenatal, 3 weeks) targeting prevention of sleep problems, as well as a sleep treatment program if requested (6-24 months). Combination participants received both interventions (9 contacts). BMI was measured at 24 months by researchers blinded to group allocation, and secondary outcomes (diet, physical activity, sleep) were assessed by using a questionnaire or accelerometry at multiple time points. RESULTS: At 2 years, 686 women remained in the study (86%). No significant intervention effect was observed for BMI at 24 months (P= .086), but there was an overall group effect for the prevalence of obesity (P = .027). Exploratory analyses found a protective effect for obesity among those receiving the "sleep intervention" (sleep and combination compared with FAB and control: odds ratio, 0.54 [95% confidence interval, 0.35-0.82]). No effect was observed for the "FAB intervention" (FAB and combination compared with sleep and control: odds ratio, 1.20 [95% confidence interval, 0.80-1.81]). CONCLUSIONS: A well-developed food and activity intervention did not seem to affect children's weight status. However, further research on more intensive or longer running sleep interventions is warranted. [ABSTRACT FROM AUTHOR]

- Abstract
Abstract: Objective: To provide a user''s guide for selecting an appropriate method to assess sedentary behaviours among children and adolescents. Design: While recommendations regarding specific instruments are not provided, the guide offers information about key attributes and considerations for objective (accelerometry; inclinometers; direct observation; screen monitoring devices) and subjective (self-report; parent report; and time use diaries/logs) approaches to assess sedentary behaviour Attributes of instruments and other factors to be considered in the selection of assessment instruments include: population (age); sample size; respondent burden; method/delivery mode; assessment time frame; physical activity information required (data output); data management; measurement error; cost (instrument and administration) and other limitations. Methods: Expert consensus among members of the Australasian Child and Adolescent Obesity Research Network''s (ACAORN) Physical Activity and Sedentary Behaviour Special Interest Group. Results: We developed decision flow charts to assist researchers and practitioners select an appropriate method of assessing sedentary behaviour, identified attributes of each method and described five real-life scenarios to illustrate considerations associated with the selection of each method of measurement. Conclusions: It is important that researchers, practitioners and policy makers understand the strengths and limitations of different methods of assessing sedentary behaviour among youth, and are guided on selection of the most appropriate instrument/s to suit their needs.

Children consume ultra-processed food (UPF) from a young age, but the proportional contribution of UPF to young children's total energy intakes has not been evaluated in developed countries. To describe UPF intake and associations with demographic factors in young children from 12 to 60 months of age. Cohort study comprising a secondary analysis of data from a randomized controlled trial. Demographic data were collected by questionnaire. At 12, 24, and 60 months of age validated food frequency questionnaires estimated percentage of energy intake from UPF (%kcal UPF). The 669 children were born in Dunedin, New Zealand, between May 2009 and December 2010. Mean percentage of energy intake from UPF at 12, 24, and 60 months of age, mean differences in %kcal UPF by demographic variables. Mixed effects regression models were used to estimate relationships between demographics and %kcal UPF. Multiple imputation methods were used to impute missing UPF data. UPF contributed mean (95% confidence interval) 45% (44%, 47%), 42% (41%, 44%), and 51% (50%, 52%) of energy intake to the diets of children at 12, 24, and 60 months of age, respectively. Energy intake from UPF was moderately correlated between 24 and 60 months (r = 0.36). No demographic factors were associated with mean %kcal UPF across time points, except for maternal obesity predicting higher UPF intake at 12 months. Bread, yoghurt, crackers, whole-wheat breakfast cereal, sausages, and muesli bars were among the 10 foods making the greatest contribution to mean %kcal UPF intakes at all time points. UPF contribute a substantial proportion of energy to the diets of young children. A range of foods with varying nutritional profiles contribute to these high intakes. [ABSTRACT FROM AUTHOR]

Introduction: Few physical activity interventions have been undertaken in infants and toddlers, despite concerns that they are insufficiently active. The Prevention of Overweight in Infancy trial encouraged parents to be physically active with their child from birth, including prone-based play ("tummy time"), while reducing time spent restrained in car seats and "strollers." Methods: A total of 802 women, recruited in late pregnancy, were randomized to a physical activity intervention, which provided information antenatally, and active group sessions with their infant at 3, 9, and 18 months of age. Questionnaires were completed at multiple time points, and toddlers wore Actical accelerometers for 5 d at 24 months of age. Results: Attendance at intervention sessions was high in infancy but declined by 18 months to 66%. Almost all parents placed their infant prone to play at least once a day (90%-95%, overall median 25 min⋅d-1), with no intervention differences observed (P = 0.445 and P = 0.350 at 4 and 6 months, respectively). Few differences were observed in other measures of restraint or parental activity at any time point. At 2 yr, children spent approximately 8 h⋅d-1 in sedentary time while awake and 3.6 h in light-to-vigorous activity. However, no group differences were apparent in counts per minute (P = 0.759) or time in light-to-vigorous activity (P = 0.960). Conclusion: An early life intervention targeting improvements in child and parent physical activity as part of a wider obesity prevention initiative had little effect on physical activity at 2 yr of age.

OBJECTIVE: To determine the impact of a baby-led approach to complementary feeding on infant choking and gagging. METHODS: Randomized controlled trial in 206 healthy infants allocated to control (usual care) or Baby-Led Introduction to SolidS (BLISS; 8 contacts from antenatal to 9 months providing resources and support). BLISS is a form of baby-led weaning (ie, infants feed themselves all their food from the beginning of complementary feeding) modified to address concerns about choking risk. Frequencies of choking and gagging were collected by questionnaire (at 6, 7, 8, 9, 12 months) and daily calendar (at 6 and 8 months); 3-day weighed diet records measured exposure to foods posing a choking risk (at 7 and 12 months). RESULTS: A total of 35% of infants choked at least once between 6 and 8 months of age, and there were no significant group differences in the number of choking events at any time (all Ps > .20). BLISS infants gagged more frequently at 6 months (relative risk [RR] 1.56; 95% confidence interval [CI], 1.13-2.17), but less frequently at 8 months (RR 0.60; 95% CI, 0.42-0.87), than control infants. At 7 and 12 months, 52% and 94% of infants were offered food posing a choking risk during the 3-day record, with no significant differences between groups (7 months: RR 1.12; 95% CI, 0.79-1.59; 12 months: RR 0.94; 95% CI, 0.83-1.07). CONCLUSIONS: Infants following a baby-led approach to feeding that includes advice on minimizing choking risk do not appear more likely to choke than infants following more traditional feeding practices. However, the large number of children in both groups offered foods that pose a choking risk is concerning. [ABSTRACT FROM AUTHOR]
