Knowledge, attitudes and practices of Australian trainee childcare educators regarding their role in the feeding behaviours of young children

Background: Early childhood (2–5 years) is acknowledged as a critical time for the establishment of healthy behaviours. The increasing number of children and amount of time spent in childcare provides strong rationale to explore the important role that childcare services and childcare educators play in influencing healthy eating behaviours of young children in their care. Methods: This study used a qualitative exploratory approach to describe the knowledge, attitudes and practices of Australian childcare trainee educators’ regarding their role in the feeding of young children. Results: All participants agreed that feeding of young children was an important part of their role, but described challenges to the promotion of healthy eating and the adoption of responsive child feeding practices. These included personal beliefs and experiences with food, the bi-directional nature of child feeding, conflicting parental requests and/or unsupportive centre-based policies and procedures. Conclusion: Training about responsive child feeding practices within the childcare sector should include all childcare staff; aim to enhance relational efficacy and communication skills with parents; and empower childcare staff to lead organisational change. To support this, childcare centres need to provide coherent centre-based healthy eating policies inclusive of healthy food provision and desirable feeding practices

Children\u27s physical activity and screen time : qualitative comparison of views of parents of infants and preschool children

BackgroundWhile parents are central to the development of behaviours in their young children, little is known about how parents view their role in shaping physical activity and screen time behaviours.MethodsUsing an unstructured focus group design, parental views and practices around children&prime;s physical activity and screen time (television and computer use) were explored with eight groups of new parents (n=61; child age &lt;12 months) and eight groups of parents with preschool-aged (3&ndash;5 year old) children (n=36) in Melbourne, Australia.ResultsParents generally believed children are naturally active, which may preclude their engagement in strategies designed to increase physical activity. While parents across both age groups shared many overarching views concerning parenting for children&prime;s physical activity and screen time behaviours, some strategies and barriers differed depending on the age of the child. While most new parents were optimistic about their ability to positively influence their child&prime;s behaviours, many parents of preschool-aged children seemed more resigned to strategies that worked for them, even when aware such strategies may not be ideal.ConclusionsInterventions aiming to increase children&prime;s physical activity and decrease screen time may need to tailor strategies to the age group of the child and address parents&prime; misconceptions and barriers to optimum parenting in these domains.<br /

A cluster randomised controlled trial of a telephone-based intervention targeting the home food environment of preschoolers (The Healthy Habits Trial): the effect on parent fruit and vegetable consumption

AbstractBackground: The home food environment is an important setting for the development of dietary patterns in childhood. Interventions that support parents to modify the home food environment for their children, however, may also improve parent diet. The purpose of this study was to assess the impact of a telephone-based intervention targeting the home food environment of preschool children on the fruit and vegetable consumption of parents.Methods: In 2010, 394 parents of 3 &ndash; 5 year &ndash; old children from 30 preschools in the Hunter region of Australia were recruited to this cluster randomised controlled trial and were randomly assigned to an intervention or control group. Intervention group parents received four weekly 30-minute telephone calls and written resources. The scripted calls focused on; fruit and vegetable availability and accessibility, parental role-modelling, and supportive home food routines. Two items from the Australian National Nutrition Survey were used to assess the average number of serves of fruit and vegetables consumed each day by parents at baseline, and 2-, 6-, 12-, and 18-months later, using generalised estimating equations (adjusted for baseline values and clustering by preschool) and an intention-to-treat-approach.Results: At each follow-up, vegetable consumption among intervention parents significantly exceeded that of controls. At 2-months the difference was 0.71 serves (95% CI: 0.58-0.85, p &lt; 0.0001), and at 18-months the difference was 0.36 serves (95% CI: 0.10-0.61, p = 0.0067). Fruit consumption among intervention parents was found to significantly exceed consumption of control parents at the 2-,12- and 18-month follow-up, with the difference at 2-months being 0.26 serves (95% CI: 0.12-0.40, p = 0.0003), and 0.26 serves maintained at 18-months, (95% CI: 0.10-0.43, p = 0.0015).Conclusions: A four-contact telephone-based intervention that focuses on changing characteristics of preschoolers&rsquo; home food environment can increase parents&rsquo; fruit and vegetable consumption.(ANZCTR12609000820202)<br /

The initiator methionine tRNA drives cell migration and invasion leading to increased metastatic potential in melanoma

The cell's repertoire of transfer RNAs (tRNAs) has been linked to cancer. Recently, levels of the initiator methionine tRNA (tRNAiMet) in stromal fibroblasts have been shown to influence extracellular matrix (ECM) secretion to drive tumour growth and angiogenesis. Here we show that increased tRNAiMet within cancer cells does not influence tumour growth, but drives cell migration and invasion via a mechanism that is independent from ECM synthesis and dependent on α5β1 integrin and levels of the translation initiation ternary complex. In vivo and ex vivo migration (but not proliferation) of melanoblasts is significantly enhanced in transgenic mice which express additional copies of the tRNAiMet gene. We show that increased tRNAiMet in melanoma drives migratory, invasive behaviour and metastatic potential without affecting cell proliferation and primary tumour growth, and that expression of RNA polymerase III-associated genes (which drive tRNA expression) are elevated in metastases by comparison with primary tumours. Thus specific alterations to the cancer cell tRNA repertoire drive a migration/invasion programme that may lead to metastasis

Development and evaluation of a food frequency questionnaire for use among young children

Background/Objectives:&nbsp;This study described the development of a parent food frequency questionnaire (FFQ) for measuring diets of young children over the past month and the validation of this FFQ against three non-consecutive 24 hour recalls.&nbsp;&nbsp;Subjects/Methods:&nbsp;Food and nutrient intakes from a 68-item FFQ were compared with three non-consecutive 24 hour recalls in a follow-up cohort of children aged 1.5, 3.5 and 5.0 years old. Data from both methods were available for 231, 172 and 187 participants at ages 1.5, 3.5 and 5.0 years, respectively.&nbsp;&nbsp;Results:&nbsp;Out of 11 nutrients, four (protein, fat, fibre, iron), two (Vitamin C, folate) and three (protein, vitamin C and folate) nutrients showed good-acceptable outcome for 2 out of 3 group-level validation tests at ages 1.5, 3.5 and 5.0 years, respectively. Of 26 food groups, good-acceptable outcome for 2 out of 3 group-level validation tests was revealed for two, four and six food groups at ages 1.5, 3.5 and 5.0 years, respectively. For individual-level validation tests, all nutrients showed good-acceptable outcome for 2 out of 3 individual level tests across three time points, except for folate at age 1.5 years and energy intake at age 3.5 years. Most food groups (22 out of 26) at age 1.5 years and all food groups at both ages 3.5 and 5.0 years showed good-acceptable outcome for 2 out of 3 individual-level validation tests.&nbsp;&nbsp;Conclusions:&nbsp;At all three time points, the FFQ demonstrated good-acceptable validity for some nutrients and food groups at group-level, and good-acceptable validity for most nutrients and food groups at individual-level. This quantitative FFQ is a valid and robust tool for assessing total diet of young children and ranking individuals according to nutrient and food intakes

Is socioeconomic status associated with dietary sodium intake in Australian children? A cross-sectional study

Objective To assess the association between socioeconomic status (SES) and dietary sodium intake, and to identify if the major dietary sources of sodium differ by socioeconomic group in a nationally representative sample of Australian children.Design Cross-sectional survey.Setting 2007 Australian National Children\u27s Nutrition and Physical Activity Survey.Participants A total of 4487 children aged 2&ndash;16 years completed all components of the survey.Primary and secondary outcome measures Sodium intake was determined via one 24 h dietary recall. The population proportion formula was used to identify the major sources of dietary salt. SES was defined by the level of education attained by the primary carer. In addition, parental income was used as a secondary indicator of SES.Results Dietary sodium intake of children of low SES background was 2576 (SEM 42) mg/day (salt equivalent 6.6 (0.1) g/day), which was greater than that of children of high SES background 2370 (35) mg/day (salt 6.1 (0.1) g/day; p&lt;0.001). After adjustment for age, gender, energy intake and body mass index, low SES children consumed 195 mg/day (salt 0.5 g/day) more sodium than high SES children (p&lt;0.001). Low SES children had a greater intake of sodium from processed meat, gravies/sauces, pastries, breakfast cereals, potatoes and potato snacks (all p&lt;0.05).Conclusions Australian children from a low SES background have on average a 9% greater intake of sodium from food sources compared with those from a high SES background. Understanding the socioeconomic patterning of salt intake during childhood should be considered in interventions to reduce cardiovascular disease.<br /

Associations between dietary intakes of first-time fathers and their 20-month-old children are moderated by fathers\u27 BMI, education and age

Children\u27s learning about food is considerable during their formative years, with parental influence being pivotal. Research has focused predominantly on maternal influences, with little known about the relationships between fathers\u27 and children\u27s diets. Greater understanding of this relationship is necessary for the design of appropriate interventions. The aim of this study was to investigate the associations between the diets of fathers and their children and the moderating effects of fathers\u27 BMI, education and age on these associations. The diets of fathers and their first-born children (n 317) in the Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program were assessed using an FFQ and 3&times;24-h recalls, respectively. The InFANT Program is a cluster-randomised controlled trial in the setting of first-time parents groups in Victoria, Australia. Associations between father and child fruit, vegetable, non-core food and non-core drink intakes were assessed using linear regression. The extent to which these associations were mediated by maternal intake was tested. Moderation of associations by paternal BMI, education and age was assessed. Positive associations were found between fathers\u27 and children\u27s intake of fruit, sweet snacks and take-away foods. Paternal BMI, education and age moderated the relationships found for the intakes of fruit (BMI), vegetables (age), savoury snacks (BMI and education) and take-away foods (BMI and education). Our findings suggest that associations exist at a young age and are moderated by paternal BMI, education and age. This study highlights the importance of fathers in modelling healthy diets for their children

Pregnant women\u27s knowledge of weight, weight gain, complications of obesity and weight management strategies in pregnancy

BACKGROUND: Obesity is increasingly common in the obstetric population. Maternal obesity and excess gestational weight gain (GWG) are associated with increased perinatal risk. There is limited published data demonstrating the level of pregnant women's knowledge regarding these problems, their consequences and management strategies.We aimed to assess the level of knowledge of pregnant women regarding: (i) their own weight and body mass index (BMI) category, (ii) awareness of guidelines for GWG, (iii) concordance of women's own expectations with guidelines, (iv) knowledge of complications associated with excess GWG, and (v) knowledge of safe weight management strategies in pregnancy. METHODS: 364 pregnant women from a single center university hospital antenatal clinic were interviewed by an obstetric registrar. The women in this convenience sample were asked to identify their weight category, their understanding of the complications of obesity and excessive GWG in pregnancy and safe and/or effective weight management strategies in pregnancy. RESULTS: Nearly half (47.8%) of the study population were overweight or obese. 74% of obese women underestimated their BMI category. 64% of obese women and 40% of overweight women overestimated their recommended GWG. Women's knowledge of the specific risks associated with excess GWG or maternal obesity was poor. Women also reported many incorrect beliefs about safe weight management in pregnancy. CONCLUSIONS: Many pregnant women have poor knowledge about obesity, GWG, their consequences and management strategies. Bridging this knowledge gap is an important step towards improving perinatal outcomes for all pregnant women, especially those who enter pregnancy overweight or obese

Dietary associations of fathers and their children between the ages of 20 months and 5 years

OBJECTIVE: To examine associations between dietary intakes of fathers and their children at child age 20 months, 3&middot;5 years and 5 years, and to determine if fathers\u27 intake predicts change in children\u27s intake between 20 months and 3&middot;5 and 5 years of age. DESIGN: The diets of fathers and their first-born children participating in the longitudinal Melbourne Infant Feeding Activity and Nutrition Trial (InFANT) Program were assessed using FFQ and three 24 h recalls, respectively. SETTING: Sixty-two pre-existing first-time parent groups were selected from fourteen local government areas within a 60 km radius of Deakin University Burwood, Victoria, Australia. SUBJECTS: Fathers and their first-born children at 20 months (n 317), 3&middot;5 years (n 214) and 5 years of age (n 208). RESULTS: Positive associations were found between fathers\u27 and children\u27s intakes of fruit and sweet snacks at 20 months (P=0&middot;001) and 5 years of age (P=0&middot;012). Fathers\u27 intake at child age 20 months was associated with change in children\u27s intake for fruit, sweet snacks and sugar-sweetened beverages between child age 20 months and 3&middot;5 years, and for sweet snacks and sugar-sweetened beverages between child age 20 months and 5 years (all P&lt;0&middot;05). After adjustment for maternal intake, fathers\u27 intake of sweet snacks remained a predictor of change in children\u27s sweet snack intake between 20 months and 3&middot;5 years of age (P=0&middot;03). CONCLUSIONS: Associations between the dietary intakes of fathers and their children commence at a young age and continue through early childhood. Fathers should be included in future interventions aimed at improving children\u27s diets
