Eating behaviour in childhood Flashcards
Weaning
happens when milk cannot satisfy infant, provide nutrients and motor skills are sufficiently developed (requires complex oral motor skills, delayed transition may miss developmental period causing problems as these skills also used in language development)
Issues with weaning
can cause problems if children given solids too early
anxiety about choking or aspiration (accidental ingestion of foods/fluids into lungs) can delay
gag reflex common in transition period, adaptive to prevent choking but can cause panic
mothers report anxiety/difficulties and seeking advice suggests gap in provision of information (Infant feeding survey 2010)
Knowing what to eat
non-edible substances distinguished through sensory qualities of food, anticipated consequences and cultural beliefs
caregivers have important role to help unlearn associations between foods and negative consequences
Pica
condition where people eat non-foods
Accepting new foods
10-20 tastes needed before ‘liking’ new food but fewer exposure needed over weaning period (Birch et al 1968)
can still accept novel food when older as continued cognitive development influences further accpetance
Food preferences
children prefer sweet/familiar foods as give greater post-ingestive feedback, dislike bitter as can suggest poisonous foods (evolutionary) and less post-ingestive feedback
Infants self-regulation
infants are good at self-regulating how much to eat, 2-5 year olds have better compensation than adults (eat more if had low energy snack and vice versa) (Birch & Dysher 1986)
eating in absence of hunger increases from 5-9 years (Birch et al 2003)
2-3 year olds eat roughly same amount when different portion sizes offered but 4-6 year olds may overeat (Rolls et al 2000)
Approaches to weaning
traditional - caregiver spoon feeds puree -> small lumps -> larger lumps -> solids
baby-led - self-feeds solid finger foods, no puree or infant specific foods
Impact of baby-led weaning
increased liking for carbs and more underweight, sweet foods most preferred and more obese in SP, suggests BLW promotes healthy food preferences and protections against obesity (Townsend & Pitchford 2012)
BLW follow post-ingestive feedback and learn carbs are more satiating
caregiver needs a varied diet
rarely ready before 6 months so may consume less food, more milk and have nutritional deficiencies
Impacts of spoon-feeding
most pre-made baby foods made of fruit so mostly sweet
learn preference for these and can’t regulate portions
prolonged duration of smooth foods delays development of oral skills (Mason et al 2005)
less exposure to different textures to so more food refusal later (Northstone et al 2001)
later introduction of lumpy solids associated with higher risk of parent-reported feeding problems (Babik et al 2021)
Inappropriate feeding
relatively common, driven by inappropriate beliefs, generational influences, confusion over guidelines
more common in mothers with depression/obesity, low SES families, non BF infants (Wasser et al 2011)
Impacts of inappropriate feeding
associated with activity level/distress and issues in child temperament?
associated with higher daily intake of over 100kcal and higher weight-for-length ratio (Thompson & Bentley 2013)
Feeding problem behaviour
Child - food refusal, rejecting bitter tastes, preference for unhealthy food
caregiver - pressure to eat, food as reward/to soothe
authoritative parenting style associated with healthiest eating habits (Ventura & Birch 2008) but unclear of direction
poor diet in childhood predicts poor diet in adulthood (Craigie et al 2011) and development of preventable diseases (obesity, cancer, heart disease) (Nicklas & Hayes 2008)
Food refusal
caused by neophobia, developing cognition, developmentally predictable (common phase in children)
Pressure to eat
predicts picky eating in adults (Batsell et al 2002), can reduce intake (Galloway et al 2006) due to negative associations or increase intake (Orrell-Valente et al 2007) as overrides internal fullness cues
associated with increased neophobia (Fisher et al 2002) and lower fruit/veg intake (Galloway et al 2005)
elicits negative comments and reduced willingness to consume pressured foods (negative long-term consequences) (Galloway et al 2005)
may be children refuse to exert control over environment as eating is one of few ways they can have control
