Associations between caloric compensation ability and eating behaviour in infants

Discrimination des expressions faciales et environnement olfactif – Corrélats cérébraux en électroencéphalographie (EEG) chez l’adulte et le très jeu…
2019
This thesis examines the mechanisms subtending the perception of emotional facial expressions and their early development using a Fast Periodic Visual Presentation (FPVS) approach coupled with electroencephalography (EEG). More specifically, we tried to characterize brain responses reflecting facial expression discrimination and to determine whether hedonic odor contexts influence these responses in adults (studies 1 and 2), and in infants at different developmental stages (studies 3 and 4).We showed specific responses to the discrimination of every facial expression in the adult brain, indicating rapid and automatic categorization of basic facial expressions (study 1). In addition, we reve…
Determinants of complementary feeding practices in infants from the ELFE study : familial health, socio-economic and demographic characteristics and …
2018
Infant feeding practices could be risk factors for cardiovascular diseases, via early nutritional programming. These practices have not been described in detail in France until now and knowing their determinants could help improve nutritional prevention interventions.For more than 11 000 children followed in the ELFE cohort (French Longitudinal Study since childhood), we calculated the age at introduction of complementary feeding (CFg) and of food groups, evaluated the uses of added sugar, salt and fat from 3 to 10 months old, and defined three principal components of early feeding. Their associations with familial characteristics were evaluated, taking in account the influence of the infan…
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…
Dietary Sugar and Fat Exposure : Determinants and Links with Sweet Taste Liking and Fat Sensation Liking
2017
Context : Dietary exposures in the first year of life could play a role in the development of food preferences in children. Aims : To characterize dietary sweet and fat exposures in infancy and to study their links with sweet taste and fat sensation liking in school-aged children. Methods : During the first year, dietary sweet and fat exposures were assessed with a nutritional approach in the EDEN study and with a sensory approach in the OPALINE study. Next, early factors related to these dietary sweet and fat exposures were analyzed. Associations between the nutritional sweet and fat exposure and sweet taste and fat sensation liking scores in 9-to-12 y old children in the EDEN study were s…
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…
Learning to Eat Vegetables in Early Life: The Role of Timing, Age and Individual Eating Traits
2014
Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to repeated exposure, data from the same experiment conducted in three groups of children from three countries (n = 332) aged 4-38 m (18.9 +/- 9.9 m) were combined and modelled. During the intervention period each child was given between 5 and 10 exposures to a novel vegetable (artichoke puree) in one of three versions (basic, sweet or added e…
A quelles saveurs les nourrissons sont-ils exposés dans la première année de vie ?
2010
International audience; Résumé Les consommations alimentaires des jeunes enfants sont influencées par leurs préférences alimentaires, lesquelles sont en partie déterminées par l'attirance pour les différentes saveurs (sucrée, salée, acide, amère et umami). Les expériences alimentaires précoces pourraient moduler cette attraction. Or aucun travail n'avait jusqu'à présent décrit les saveurs de l'alimentation des nourrissons au cours de la première année. Tel est l'objectif de cette étude. Les caractéristiques de l'alimentation de 76 nourrissons ont été consignées par leurs parents pendant une semaine par mois au cours de la première année. Ce suivi a conduit à recenser 2902 aliments a priori …
Lipid content and essential fatty acid (EFA) composition of mature Congolese breast milk are influenced by mothers' nutritional status: Impact on inf…
1998
To measure the lipid content and the fatty acid (FA) composition of breast milk as part of a nutritional survey of the essential fatty acid (EFA) status of 5 months old Congolese infants.Cross sectional nutrition survey.A suburban district of Brazzaville (capital of the Congo).A random sample of nursing mothers and their 5 months old infants (n = 102). Data collection procedures: The mothers were questioned on their socio-economic status, dietary habits, and their body mass index (BMI) was measured. Breast milk samples were collected from each mother. Milk lipid content and fatty acid composition were determined.Compared with milk from various countries, Congolese women's mature breast milk…
