Olfactory responses: attraction or avoidance of food odours in the first two years of life?
2012
National audience; Olfaction is a salient sensory modality early in life. Neonates show keen olfactory sensitivity and hedonic responsiveness. However, little is known on how olfactory responses develop over the first two years, especially in term of hedonics. Besides, olfaction plays an important role in the perception and appreciation of foods. Here, we aim to assess hedonic reactivity to food odours in the first two years of life in the context of a longitudinal study on the development of food preferences (OPALINE). Olfactory tests were conducted on 235 participants at 8, 12, 22 months. Scented and unscented bottles were presented successively and sequentially to them. The stimuli consi…

Chemosensory reactivity and food neophobia in preschool children: impact of smell, but not of taste
2014
Context and objective: Recent studies suggested that sensory sensitivity could be linked to food neophobia, described as the reluctance to eat, or the avoidance of, new foods. The objective of the present study was twofold. Firstly, this study aimed at assessing the links between smell reactivity and taste reactivity in children. Secondly, this study assessed the links between children’s smell/taste reactivity and food neophobia. The hypothesis was that the higher the chemosensory reactivity of the child, the more the child is neophobic. Method: One hundred and three dyads of mother-child, from the Opaline cohort, were involved. The child’s food neophobia was assessed using a validated pare…
A path analysis model: how liking for vegetables emerges in children

A path analysis model is used to explain how preference for vegetables emerges before 2 years. It takes into account several determinants such as the child exposition, the child preferences for odors and flavors, as well as the parental behavior.

L'alimentation périnatale en France, entre normes et pratiques. Synthèse des publications de la cohorte ELFE
2019
National audience; L'alimentation est au coeur des premières interactions avec le nourrisson. Du fait de la biologie de la grossesse et de l'allaitement, mais aussi de l'assignation traditionnelle des femmes aux tâches nourricières, la mère est de fait l'actrice de cette prime alimentation. Loin de n'être qu'une affaire de femmes, l'alimentation périnatale est aussi une préoccupation des pouvoir publics qui contribuent à son cadrage médical, normatif et à la diffusion des recommandations nutritionnelles en la matière. Dans ce contexte, comment les femmes nourrissent-elles leurs enfants? Leurs pratiques sont-elles en adéquation avec les recommandations? Comment varient-elles selon l'apparten…

P231: Déterminants socioculturels de l’initiation et de la durée d’allaitement en France : premiers résultats de l’étude nationale ELFE
2014
Introduction et but de l’etude Le lait maternel est la source d’alimentation la plus adequate pour les nourrissons pendant les 1ers mois de vie. L’Organisation Mondiale de la Sante (OMS) preconise un allaitement maternel exclusif jusqu’a 6 mois, puis un allaitement partiel complete avec des aliments de diversification adaptes jusqu’a 2 ans1. En France, la derniere enquete nationale perinatale, realisee en 2010, a revele que, malgre les recommandations de l’OMS, le taux d’allaitement a la naissance etait de 60 %2. Recemment, l’etude EPIFANE a indique que le taux d’allaitement diminuait a 35 % a 1 mois post-partum3. Il a ete mis en evidence que des facteurs demographiques et socioculturels po…

Liking the odour, liking the food. Toddlers' liking of strongly flavoured foods correlates with liking of their odour
2014
Olfaction plays a significant role in the sensing of foods. However, little information is available at any age on the relationship between the hedonic responses to given food odours and the effective liking and disliking of foods bearing these same odours. The present study aimed to assess the relationships between food odour liking and liking of the corresponding foods. This study relied on a longitudinal design involving 235 toddlers who were assessed for both their observed liking of a set of food odours and their parent-reported liking of foods at 12 and 22 months. To assess odour liking, eight odorants representing pleasant and unpleasant foods were presented in bottles along with neu…
Evolution of olfactory responses in the first two years of life : effect of early exposures and link with food behaviour
2013
The role of taste on food preferences has already been investigated, however, little is known about the role of olfaction. The main objectives of this work were to assess infants’ olfactory responses, their dynamic during the first two years of life, and also their links with early food exposures, food liking and infants’ food neophobia. This work was conducted within a longitudinal study named OPALINE (Observatory of food preferences in infants and children). Olfactory responses were assessed, in 8-, 12- and 22-month-old infants, towards pleasant odours, such as vanilla, and unpleasant odours, such as fish. The results reveal that, from 8 months, infants can discriminate pleasant and unple…

Smell but not taste reactivity is related to food neophobia in toddlers: results from the Opaline cohort
2014
National audience; Context and objective: Research has previously identified relationships between chemosensory reactivity and food neophobia in toddlers. However, most studies have addressed this question using declarative data, and without analyzing separately smell and taste. The objective of the present study was twofold. The first objective was to assess the relationships between olfactory reactivity and taste reactivity in toddlers, using experimental designs with different tastants and odorants. The second objective was to determine the relationships between olfactory /taste reactivity and food neophobia in toddlers. The hypothesis was that the higher the chemosensory reactivity of t…

National audience; Introduction. Le Programme National Nutrition Santé (PNNS) recommande l’initiation de la diversification alimentaire entre le 5ème et le 6ème mois du nourrisson avec une introduction progressive des groupes d’aliments. Cependant, les caractéristiques de cette initiation sont mal connues en France. Notre objectif est donc de déterminer les facteurs associés à l’initiation de la diversification alimentaire. Sujets et méthodes. Les données utilisées sont issues de l’Etude longitudinale française depuis l’enfance (Elfe) , qui a inclus . Pplus de 18 000 enfants, nés dans un échantillon représentatif de maternités, ont été recrutés en 2011. Un questionnaire portant sur l’introd…

International audience; OBJECTIVE: To assess the role of the mother's mother and mothers' previous personal experiences with breastfeeding and childcare in breastfeeding practices. DESIGN AND SETTING: The analysis included 13,774 mother-infant dyads from the French national birth cohort ELFE. Feeding practices were assessed by face-to-face interview in maternity wards in 2011, by phone interviews at months 2 and 12 post-partum and by Internet/paper questionnaires monthly from months 3-10. Sociodemographic, maternal and newborn-related factors were collected in the maternity unit and by postnatal phone interview at month 2. Multivariable logistic and linear regression was used to assess the …
Infants' hedonic responsiveness to food odours: a longitudinal study during and after weaning (8, 12 and 22 months)
2013
Abstract Background Olfaction is a highly salient sensory modality in early human life. Neonates show keen olfactory sensitivity and hedonic responsiveness. However, little is known about hedonic olfactory responsiveness between the neonatal period and 2 years of age. In an attempt to fill this gap, this longitudinal follow-up study aimed at investigating hedonic responses to food odours in infants during the first 2 years of life. The second objective was to evaluate whether gender has an influence on hedonic responses during this early period. Four control stimuli and eight odours (four rated by adults as a priori pleasant and four a priori unpleasant) were presented in bottles to 235 inf…
