Abstract
BACKGROUND
Childhood obesity is associated with serious comorbidities during childhood and into adulthood. One potential risk factor for childhood obesity is consumption of unhealthy, energy-dense foods. This scoping review examines evidence on snacking in children aged 2-12years of age and presents the patterns and position of snacking in children's diets.
METHODS
A search of electronic databases (MEDLINE, Web of Science, PubMed, Embase) for articles published from March 2011 to November 2022 was conducted. Articles providing insight into the position of snacking (e.g., energy contribution), or patterns (e.g., location, timing), in children aged 2-12years were included. A quality assessment was conducted and data was synthesised according to data source (nationally representative or other).
RESULTS
Twenty-one articles were included, most (n = 13) reporting nationally representative data. The average number of daily snacks was 3, with 92.9-100.0% of children consuming snacks. Most were consumed in the afternoon (75.2-84.0%) and at home (46.5-67.3%). Snacks frequently consumed were 'fruits and vegetables', 'baked desserts', 'sweets, candy and confectionery', and 'dairy products'. Snacks contributed 231-565 kcal daily, up to a third of daily carbohydrate intake, a quarter of fat intake, and a fifth of protein intake. Snacks provided up to one third of vitamin C intake, one quarter of vitamin E, potassium and magnesium intake, and a fifth of calcium, folic acid, vitamins D and B12, iron and sodium intake.
DISCUSSION
This scoping review provides insight into patterns and position of snacking within children's diets. Snacking plays a significant role in children's diets with multiple snacking occasions occurring throughout a child's day, the overconsumption of which has the potential to increase risk of childhood obesity. Further research is required into the role of snacking, particularly specific foods playing a role in micronutrient intake, and clear guidance for snacking intake in children.
