Why the complementary feeding period

Why the Complementary Feeding Period?

  • Nutritionally sensitive period

    • Breastfeeding duration

    • Age of introduction of solids

    • Type, amount and composition of food

      • Supply of energy and nutrients

  • Establishment of lifelong dietary behaviours

    • Food habits

    • Taste and texture preferences

  • Implications for later diet, health and development


What s the challenge

What’s the Challenge?

  • Three studies ‘diet quality’ <12 mo age Smithers et al Nutr Reviews 2011

    • Nutrient adequacy, Diet diversity

    • Child Feeding Index

  • Complementary feeding guidelines

    • Sufficient nutritious food for growth, development & health (amount, quality, variety, moderation)

    • Developmentally appropriate (timing, texture)

    • ‘How’ to feed (responsive feeding, persistence)


  • Study aim

    Study Aim

    • To development an index to characterise quality of the complementary feeding period

      • adherence to complementary feeding guidelines

      • developed country context

      • address (some) methodological challenges

    • To examine the face validity of the Complementary Feeding Utility Index (CFUI)

      • Food and nutrient intake

      • sociodemographic characteristics

      • Dietary patterns in childhood


    Summary of diet index construction

    Summary of Diet Index Construction

    Selection of index components

    Quantification of component scores

    Summing of component scores

    Adapted Kourlabaet al 2009

    TOTAL SCORE ‘Diet quality’


    Cfui 14 components

    CFUI: 14 components

    Breastfeeding (months)

    0 1 2 3 4 5 6 7 8 9 10 11 12

    0 5 10

    Energy dense nutrient poor foods (types)

    0 1 2 3 4 5 6

    0 5 10

    Fed on demand (categorical )

    N S Y

    0 5 10


    Quantification of component scores conversion to probabilities

    Quantification of component scores: Conversion to Probabilities

    Variety of Protein foods

    = # children having 1 to 3 types protein foods - # having 1 or 2 or 3 types

    # children having 1 to 3 types protein foods

    = 9747 - # children having 1 type protein foods i.e. 4735

    9747

    = 0.51


    Quantification of component scores theoretical derived probabilities

    Quantification of component scores: Theoretical Derived Probabilities


    How to derive a total score

    How to derive a total score?

    • Each component has score of 0 to 1

    • Sum or mean: various pathways=same score

    • Inverse Euclidian norm: how each component score varies from guideline adherence


    Mean cfui score 0 48 0 1

    Mean CFUI score = 0.48±0.1

    N=6065

    6 mo


    Association with energy adjusted nutrient intake

    Association with energy-adjusted nutrient intake

    Nutrient intake at 8 months of age for Children In Focus sub-sample (n=989)


    Socio demographic factors

    Socio-demographic factors

    • Higher Complementary Feeding Utility Index scores were associated with

      • older maternal age

      • higher maternal education level

      • Healthy maternal weight status.

    • Higher Complementary Feeding Utility Index scores were not associated with

      • Number of siblings


    Association with d ietary patterns at 3 y

    Association with Dietary Patterns at 3 y

    N=6065

    Adjusted models; dietary pattern scores, child, maternal and family socio-demographics


    Conclusions

    Conclusions

    • The Complementary Feeding Utility Index

      • reflects adherence to early feeding guidelines

      • has face validity as a composite measure of early diet quality

      • scores were associated with food and nutrient intake largely in the expected direction

    • Methodological challenges addressed

      • components that are unit free

      • Scoring range based on observed/ theoretical preferences

      • Contribution of components to total score

    • Next steps

      • Predictive validity: association with child health and development outcomes
