Early childhood is critical to the development of lifelong food habits. Given the high proportion of children with inadequate fruit and vegetable consumption, identification of modifiable factors associated with higher consumption may be useful in developing interventions to address this public health issue. This study aimed to identify the characteristics of the home food environment that are associated with higher fruit and vegetable consumption in a sample of Australian preschool children.
A cross-sectional telephone survey was conducted with 396 parents of 3 to 5 year-old children attending 30 preschools within the Hunter region, New South Wales, Australia. Children's fruit and vegetable consumption was measured using a valid and reliable subscale from the Children's Dietary Questionnaire. Associations were investigated between children's fruit and vegetable intake and characteristics of the home food environment including parental role-modeling, parental providing behaviour, fruit and vegetable availability, fruit and vegetable accessibility, pressure to eat, family eating policies and family mealtime practices. Characteristics of the home food environment that showed evidence of an association with children's fruit and vegetable consumption in simple regression models were entered into a backwards stepwise multiple regression analysis. The multiple regression analysis used generalised linear mixed models, controlled for parental education, household income and child gender, and was adjusted for the correlation between children's fruit and vegetable consumption within a preschool.
The multiple regression analysis found positive associations between children's fruit and vegetable consumption and parental fruit and vegetable intake (p=0.005), fruit and vegetable availability (p=0.006) and accessibility (p=0.012), the number of occasions each day that parents provided their child with fruit and vegetables (p<0.001), and allowing children to eat only at set meal times all or most of the time (p=0.006). Combined, these characteristics of the home food environment accounted for 48% of the variation in the child's fruit and vegetable score.
This study identified a range of modifiable characteristics within the home food environment that are associated with fruit and vegetable consumption among preschool children. Such characteristics could be considered potential targets for interventions to promote intake among children of this age.

    • "Among non-rural populations, evidence suggests associations between children's eating behaviors and family-level factors including parent education and role modeling1415161718, family food rules[14,19], and family meal patterns20212223. Additionally, other home environmental factors, such as availability of healthy foods[14,18,24], eating while watching TV[25], and fast food consumption[15,25], may make it easier or harder for children to eat healthfully. Unfortunately, research examining these and other obesity-promoting or -preventing factors in rural family-home settings is limited. "

    ABSTRACT: Obesity and food insecurity rates are higher among rural compared to non-rural populations. Little is known, however, about how family-home environments influence childhood obesity-related behaviors, particularly in rural settings. This study examined associations between the family-home nutrition (FN) environment, food insecurity, and dietary intake (fruits, vegetables, whole grains, dairy, protein foods, and added sugars) in rural elementary school-age children (grades K-5/6; n = 102). Parents/caregivers completed surveys on FN, food insecurity, and the Block Kids Food Screener (BKFS). Body mass index (BMI, kg/m2) was calculated from measured height and weight. Approximately 33% of children were classified as overweight/obese and 28% of families were at-risk for food insecurity. Multivariable linear regression analyses examined associations between dietary intakes with FN and food insecurity. More favorable FN scores were associated with lower added sugar intake (B = ̵ 1.38, p = 0.04) and higher vegetable (B = 0.15, p < 0.001), fruit (B = 0.71, p = 0.01), and dairy (B = 0.31, p < 0.001) intakes. No significant associations were found between food insecurity and dietary intake. Given the association between higher FN scores and more favorable dietary intake, promoting healthy FN environments among rural children is warranted

    • "However, regarding food intake, the strong negative association between cost and home availability of certain food items (i.e., low cost of energy dense foods compared to more expensive healthy foods, such as fruits and vegetables), particularly for population subgroups of lower socio-economic status groups, highlights the need for assessing food cost as well [273] . To date, there is strong evidence indicating that food availability at home is positively associated with the actual consumption of the respective healthy (e.g., fruits, vegetables , whole grain cereals, etc.) [6,217,250,274] or unhealthy (e.g., soft drinks, confectionary, etc.) foods [21,275] . Furthermore, other studies have also highlighted food accessibility as a strong physical environmental factor influencing the actual consumption of the respective healthy or unhealthy foods [21]. "

    ABSTRACT: Clinical manifestations of cardiometabolic risk (CMR) may be set early in childhood due to unfavorable behaviors or lifestyle patterns related to diet and physical activity. Several factors may determine the adoption of such lifestyle-related behaviors, which researchers have tried to cluster under certain frameworks or models. In this context, the framework developed and proposed by this review gathers all the present knowledge regarding these determining factors to date and groups them into three main categories related to personal characteristics and the social and physical environment. Based on the proposed framework, a large variety of personal, social and physical environmental factors can positively or negatively influence CMR-related behaviors (either directly or indirectly via their interrelations), thus leading to decreased or increased risk, respectively. This framework could be of great value to public health policy makers and legislators for designing and implementing interventional programs tailored to the needs of susceptible population groups who are most in need for such initiatives. Targeting the correlates as potential determinants of CMR-related behaviors, and not just on the behaviors themselves, has been shown previously to be the most effective approach for tackling health issues related to CMR starting from early life stages.

    ABSTRACT: BACKGROUND: Consumption of non-core foods in childhood is associated with excessive weight gain in childhood. Parents play a vital role in establishing healthy diet behaviours in young children. The aim of this study was to assess the effectiveness of a telephone-based intervention in reducing child consumption of non-core foods, and to examine parent and home food environment mediators of change in child consumption. METHODS: The 'Healthy Habits' trial utilised a clustered randomised controlled design.Setting/participants: Parents were recruited from 30 preschools (N = 394 participants, mean age 35.2+/-5.6 years). Parents randomized to the intervention group received four telephone contacts and print materials. Parents allocated to the control condition receive generic print materials only. Non-core food consumption was assessed using a validated child dietary questionnaire at baseline, 2 and 6 months post recruitment in 2010. RESULTS: The intervention was effective in reducing child consumption of non-core foods at 2 months (intention to treat analysis: z=-2.83, p<.01), however this effect was not maintained at 6 months. Structural equation modelling using 2 month data indicated that child access to non-core foods in the home and child feeding strategies mediated the effect of the intervention. CONCLUSION: The telephone-based intervention shows promise in improving short term dietary behaviour in preschool age children, however further development is needed to sustain the effect in the long-term.Trial registration: Australian Clinical Trials Registry: ACTRN12609000820202.
