A comparison between the feeding practices of parents and grandparents

Grandparents play a valuable role in the socialisation of young children, and as many as 36% of British parents use grandparents as their main form of childcare. Research has begun to explore how grandparents impact the social and cognitive development of children, but very little research has evaluated their contribution to child feeding. The present study explores whether there are differences between parents and grandparents in terms of their feeding practices, and whether grandparents' feeding practices are related to the number of hours that they spend caring for grandchildren. Results indicate that grandparents reported using significantly more maladaptive feeding practices such as using food to regulate emotions and restricting food, but more positive practices such as providing a healthy food environment. The more hours that grandparents spent caring for children the more their feeding practices resembled those broadly reported by parents. Results suggest that grandparents can have a measurable impact on child feeding behaviour which in turn is likely to predict the eating behaviours of their grandchildren. © 2014 Elsevier Ltd.

Teaching our children when to eat:how parental feeding practices inform the development of emotional eating-a longitudinal experimental design

Background: Emotional eating in children has been related to the consumption of energy-dense foods and obesity, but the development of emotional eating in young children is poorly understood. Objectives: We evaluated whether emotional eating can be induced in 5-7-y-old children in the laboratory and assessed whether parental use of overly controlling feeding practices at 3-5 y of age predicts a greater subsequent tendency for children to eat under conditions of mild stress at ages 5-7 y. Design: Forty-one parent-child dyads were recruited to participate in this longitudinal study, which involved parents and children being observed consuming a standard lunch, completing questionnaire measures of parental feeding practices, participating in a research procedure to induce child emotion (or a control procedure), and observing children's consumption of snack foods. Results: Children at ages 5-7 y who were exposed to a mild emotional stressor consumed significantly more calories from snack foods in the absence of hunger than did children in a control group. Parents who reported the use of more food as a reward and restriction of food for health reasons with their children at ages 3-5 y were more likely to have children who ate more under conditions of negative emotion at ages 5-7 y. Conclusions: Parents who overly control children's food intake may unintentionally teach children to rely on palatable foods to cope with negative emotions. Additional research is needed to evaluate the implications of these findings for children's food intake and weight outside of the laboratory setting. This trial was registered at clinicaltrials.gov as NCT01122290.

Eating behaviours of preadolescent children over time:stability, continuity and the moderating role of perceived parental feeding practices

The links between childhood eating behaviours and parental feeding practices are well-established in younger children, but there is a lack of research examining these variables in a preadolescent age group, particularly from the child's perspective, and longitudinally. This study firstly aimed to examine the continuity and stability of preadolescent perceptions of their parents' controlling feeding practices (pressure to eat and restriction) over a 12 month period. The second aim was to explore if perceptions of parental feeding practices moderated the relationship between preadolescents' eating behaviours longitudinally. Two hundred and twenty nine preadolescents (mean age at recruitment 8.73 years) completed questionnaires assessing their eating behaviours and their perceptions of parental feeding practices at two time points, 12 months apart (T1 and T2). Preadolescents' perceptions of their parental feeding practices remained stable. Perceptions of restriction and pressure to eat were continuous. Perceptions of parental pressure to eat and restriction significantly moderated the relationships between eating behaviours at T1 and T2. The findings from this study suggest that in a preadolescent population, perceptions of parental pressure to eat and restriction of food may exacerbate the development of problematic eating behaviours.

Infant feeding practices of Cuban mothers residing in Dade County, Florida

Research has shown that infant feeding practices differ between cultures. A convenience sample of 51 first generation Cuban mothers with infants birth to 12 months of age were surveyed to identify their infant feeding practices, and why they introduce foods to their infants in the manner in which they do. Data obtained from the mothers' responses to an English/Spanish Questionnaire were summarized by frequencies. Findings revealed that Cuban mothers consider a variety of foods from the major four food groups to be suitable for their infants. They introduced solids to their infants at the average age of four months and fed their infants in the manner in which they did because they thought it was healthy/nutritious. Cuban mothers may feed their infants as taught by health care professionals if their infant feeding practices are incorporated in the culture specific infant feeding programmes developed by the health team.

Parental influences and mothers’ experiences on infant and young child feeding practices

The objective of this thesis was to better understand how parental factors influence feeding practices, how mothers experience feeding and what factors mothers perceive influencing feeding in different contexts. This study is largely based on STEPS Study (Steps to Healthy Development of Children), which is a longitudinal cohort of 1797 families. In addition, qualitative data was collected among mothers in Finland and Solomon Islands. The results of this study show that different parental determinants associate with infant and young child feeding behavior and practices. Mothers with high cognitive restraint of eating introduced complementary foods earlier and neophobic mothers’ breastfed exclusively for a shorter time than mothers who ranked lower in these behaviors. Fathers’ poor diet quality associated with shorter total breastfeeding duration. Mothers’ postnatal depressive symptoms associated with shorter duration of exclusive breastfeeding, earlier introduction of complementary foods and lower compliance of feeding recommendations. The higher amount of marital distress associated with longer duration of exclusive breastfeeding and better compliance with feeding recommendations. Mothers, who participated in qualitative interviews, described how complex interplay of individual perceptions, significant others and socio-cultural environment influenced feeding practices and behavior. This study showed that several parental factors influence infant and young child feeding practices as well as compliance with the feeding recommendations. Maternal experiences and perceptions on child feeding relate to the context where mother-infant pair lives in. These results highlight the importance of targeting feeding support and, if needed, specific interventions to mothers and families who are in risk of poor feeding practices.

Parent modeling and child food consumption

Obesity, among both children and adults, is a growing public health epidemic. One area of interest relates to how and why obesity is developing at such a rapid pace among children. Despite a broad consensus about how controlling feeding practices relate to child food consumption and obesity prevalence, much less is known about how non-controlling feeding practices, including modeling, relate to child food consumption. This study investigates how different forms of parent modeling (no modeling, simple modeling, and enthusiastic modeling) and parent adiposity relate to child food consumption, food preferences, and behaviors towards foods. Participants in this experimental study were 65 children (25 boys and 40 girls) aged 3-9 and their parents. Each parent was trained on how to perform their assigned modeling behavior towards a food identified as neutral (not liked, nor disliked) by their child during a pre-session food-rating task. Parents performed their assigned modeling behavior when cued during a ten-minute observation period with their child. Child food consumption (pieces eaten, grams eaten, and calories consumed) was measured and food behaviors (positive comments toward food and food requests) were recorded by event-based coding. After the session, parents self-reported on their height and weight, and children completed a post-session food-rating task. Results indicate that parent modeling (both simple and enthusiastic forms) did not significantly relate to child food consumption, food preferences, or food requests. However, enthusiastic modeling significantly increased the number of positive food comments made by children. Children's food consumption in response to parent modeling did not differ based on parent obesity status. The practical implications of this study are discussed, along with its strengths and limitations, and directions for future research.^

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation

The transition period is associated with the peak incidence of production problems, metabolic disorders and infectious diseases in dairy cows (Drackley, 1999). During this time the cow’s immune system seems to be weakened; it is apparent that metabolic challenges associated with the onset of lactation are factors capable of affecting immune function. However, the reasons for this state are not entirely clear (Goff, 2006). The negative energy balance associated with parturition leads to extensive mobilization of fatty acids stored in adipose tissue, thus, causing marked elevations in blood non-esterified fatty acids (NEFA) and B-hydroxybutyrate (BHBA) concentrations (Drackley et al., 2001). Prepartal level of dietary energy can potentially affect adipose tissue deposition and, thus, the amount of NEFA released into blood and available for metabolism in liver (Drackley et al., 2005). The current feeding practices for pregnant non-lactating cows has been called into question because increasing amounts of moderate-to-high energy diets (i.e. those more similar to lactation diets in the content of energy) during the last 3 wk postpartum have largely failed to overcome peripartal health problems, excessive body condition loss after calving, or declining fertility (Beever, 2006). Current prepartal feeding practices can lead to elevated intakes of energy, which can increase fat deposition in the viscera and upon parturition lead to compromised liver metabolism (Beever, 2006, Drackley et al., 2005). Our general hypothesis was that overfeeding dietary energy during the dry period, accompanied by the metabolic challenges associated with the onset of lactation would render the cow’s immune function less responsive early postpartum. The chapters in this dissertation evaluated neutrophil function, metabolic and inflammation indices and gene expression affected by the plane of dietary energy prepartum and an early post-partum inflammatory challenge in dairy cows. The diet effect in this experiment was transcendental during the transition period and potentially during the entire lactation. Changes in energy balance were observed and provided a good model to study the challenges associated with the onset of lactation. Overall the LPS model provided a consistent response representing an inflammation incident; however the changes in metabolic indices were sudden and hard to detect in most of the cases during the days following the challenge. In general overfeeding dietary energy during the dry period resulted in a less responsive immune function during the early postpartum. In other words, controlling the dietary energy prepartum has more benefits for the dairy cow during transition.

Variations between post- and pre-harvest seasons in stunting, wasting, and Infant and Young Child Feeding (IYCF) practices among children 6-23 months of age in lowland and midland agro-ecological zones of rural Ethiopia

Introduction: Food availability and access are strongly affected by seasonality in Ethiopia. However, there are little data on seasonal variation in Infant and Young Child Feeding (IYCF) practices and malnutrition among 6-23 months old children in different agro-ecological zones of rural Ethiopia. Methods: Socio-demographic, anthropometry and IYCF indicators were assessed in post- and pre-harvest seasons among children aged 6–23 months of age randomly selected from rural villages of lowland and midland agro-ecological zones. Results: Child stunting and underweight increased from prevalence of 39.8% and 26.9% in post-harvest to 46.0% and 31.8% in pre-harvest seasons, respectively. The biggest increase in prevalence of stunting and underweight between post- and pre-harvest seasons was noted in the midland zone. Wasting decreased from 11.6% post-harvest to 8.5% pre-harvest, with the biggest decline recorded in the lowland zone. Minimum meal frequency, minimum acceptable diet and poor dietary diversity increased considerably in pre-harvest compared to post-harvest season in the lowland zone. Feeding practices and maternal age were predictors of wasting, while women’s dietary diversity and children age was predictor of child dietary diversity in both seasons. Conclusion: There is seasonal variation in malnutrition and IYCF practices among children 6-23 months of age with more pronounced effect in midland agro-ecological zone. A major contributing factor for child malnutrition may be poor feeding practices. Health information strategies focused on both IYCF practices and dietary diversity of mothers could be a sensible approach to reduce the burden of child malnutrition in rural Ethiopia.

Persistence of a biocontrol Pseudomonas inoculant as high populations of culturable and non-culturable cells in 200-cm-deep soil profiles

Little is known about the ecology of soil inoculants used for pathogen biocontrol, biofertilization and bioremediation under field conditions. We investigated the persistence and the physiological states of soil-inoculated Pseudomonas protegens (previously Pseudomonas fluorescens) CHA0 (108 CFU g−1 surface soil) in different soil microbial habitats in a planted ley (Medicago sativa L.) and an uncovered field plot. At 72 days, colony counts of the inoculant were low in surface soil (uncovered plot) and earthworm guts (ley plot), whereas soil above the plow pan (uncovered plot), and the rhizosphere and worm burrows present until 1.2 m depth (ley plot) were survival hot spots (105-106 CFU g−1 soil). Interestingly, strain CHA0 was also detected in the subsoil of both plots, at 102-105 CFU g−1 soil between 1.8 and 2 m depth. However, non-cultured CHA0 cells were also evidenced based on immunofluorescence microscopy. Kogure's direct viable counts of nutrient-responsive cells showed that many more CHA0 cells were in a viable but non-culturable (VBNC) or a non-responsive (dormant) state than in a culturable state, and the proportion of cells in those non-cultured states depended on soil microbial habitat. At the most, cells in a VBNC state amounted to 34% (above the plow pan) and those in a dormant state to 89% (in bulk soil between 0.6 and 2 m) of all CHA0 cells. The results indicate that field-released Pseudomonas inoculants may persist at high cell numbers, even in deeper soil layers, and display a combination of different physiological states whose prevalence fluctuates according to soil microbial habitats.

Attitudes et pratiques d’éducatrices en milieux de garde au Québec à l’égard de l’alimentation des enfants

Contexte. De plus en plus d’enfants fréquentent les milieux de garde et y consomment leur repas. Les éducatrices présentes constituent des modèles dont les attitudes et les pratiques alimentaires peuvent contribuer au développement des habitudes alimentaires des enfants. Toutefois, peu d’études ont été menées sur le sujet. Objectifs. Décrire les attitudes et les stratégies d’éducatrices en milieux de garde au Québec à l’égard de l’alimentation des enfants et dégager les styles alimentaires dominants. Méthode. La collecte de données a eu lieu par sondage sur le site Web www.nospetitsmangeurs.org. À partir de 86 énoncés, la recherche a documenté les styles et pratiques alimentaires des éducatrices au moyen de huit mises en situation : mets principal non apprécié par l’éducatrice, aliment particulier non apprécié par un enfant, nouveau mets non désiré par les enfants, enfant difficile ne voulant pas manger, enfant qui n’a pas faim, fillette avec embonpoint, fillette de petit poids et enfant n’ayant pas terminé son repas. Analyse statistique. Des statistiques descriptives, des échelles de fiabilité et des corrélations ont été générées. Des tests de t pour échantillons appariés ont également été utilisés pour évaluer le degré relatif des styles alimentaires. Résultats. Au total, 371 répondants ont rempli l’ensemble du questionnaire. Globalement, les éducatrices étudiées utilisent le style alimentaire démocratique. Celles-ci mentionnent représenter des modèles pour les enfants. Elles encouragent aussi les enfants à manger et utilisent la division des responsabilités. Paradoxalement, la pratique alimentaire associée au style autoritaire la plus utilisée est la pression à manger, pratique en opposition avec le concept de division des responsabilités. Conclusion. Cette étude indique que les éducatrices démontrent des attitudes positives à l’égard de l’alimentation des enfants. Malgré certaines discordances à l’égard de stratégies utilisées, ces résultats sont encourageants, car le style alimentaire démocratique permet aux enfants de reconnaitre leurs signaux de faim et de satiété.

Estudio descriptivo de las prácticas y percepción de seguridad alimentaria y nutricional del municipio de Pacho Cundinamarca, 2014

El presente documento tuvo como objetivo el diagnóstico de las prácticas de alimentación de interés en nutrición y salud pública y la percepción de seguridad alimentaria en los hogares del municipio de Pacho departamento de Cundinamarca, información que permitió hacer análisis descriptivo de las frecuencias de consumo de los grupos alimentarios y la cualificación de seguridad en cuanto al acceso a los alimentos. Lo anterior se desarrolló mediante la adaptación de dos de los cinco formularios estructurados para la encuesta nacional de situación nutricional en Colombia del año 2010 liderado por el ministerio de protección social; las encuestas fueron realizadas a 400 personas jefe de hogar de acuerdo a muestreo aleatorio estratificado. El estudio mostró que hay inseguridad alimentaria total en un 34,7%, lo que incluye una percepción de inseguridad en un 3% del total de las familias encuestadas. Por último el estudio permitió concluir la importancia de fortalecer los programas de gobierno existentes, en aras de permitir el favorecimiento de la seguridad alimentaria y nutricional y el cambio de hábitos de nutrición desde una perspectiva intersectorial donde se incluyan los factores sociales, culturales, económicos y ecológicos de la comunidad orientados a estilos de vida saludables transcendentales en prevenir y disminuir el riesgo de enfermedades crónicas no transmisibles.

Dietary practices and nutritional status of 0-24-month-old children from Brazilian Amazonia

Objective: To assess the nutritional status and dietary practices of 0-24-month-old children living in Brazilian Amazonia. Design: Cross-sectional study. Information oil children`s dietary intakes was obtained from diet history data. Weight and length Were measured for anthropometric evaluation. Fe status Was assessed Using fasting venous blood samples; Hb, serum ferritin and soluble tranferrin receptor concentrations were measured. Setting: The towns of Assis Brasil and Acrelandia in the state of Acre, north-west Brazil. Subjects: A total of sixty-nine randomly selected 0-24-month-old children. Results: Of these children, 40.3 % were anaemic, 63.1% were Fe-deficient, 28.1% had Fe-deficiency anaemia and 11.6% were stunted. Breast-feeding was initiated by 97.1% of mother followed by early feeding with complementary foods. The dietary pattern reflected a high intake of carbohydrate-rich foods and cow`s milk, with irregular intakes Of fruit, Vegetables and meat. All infants and 92.3% of toddlers were at risk Of inadequate Fe intakes. Fe from animal foods contributed Oil average 0.5% and 14.3% to total dietary Fe intake among infants and toddlers, respectively. Conclusions: Poor nutritional status and inadequate feeding practices in this study population reinforce the importance of exclusive breast-feeding during the first 6 months of life. Greater emphasis is required to improve the bioavailability of dietary Fe during complementary feeding practices.

Considera-se 46 min., tempo mais adequado para avaliar atratividade de algodoeiro a lagartas de S. frugiperda.

Efeito da prática de alimentação infantil e de fatores associados sobre a ocorrência da cárie dental em pré-escolares de 18 a 48 meses

Este estudo foi realizado objetivando estudar o efeito das práticas de alimentação infantil e de fatores associados sobre a ocorrência de cárie dental. Para isso, determinou-se o ceo-d e o ceo-s em 156 crianças de 18 a 48 meses e foi aplicado às mães um questionário incluindo perguntas sobre a ocupação do pai, nível educacional da mãe, higiene bucal, época de erupção do dente e sobre práticas de alimentação infantil. Os dados obtidos foram analisados através dos testes X2 e Mann-Whitney U. A média do ceo-s foi 3,4 com 40% das crianças livres de cáries, sendo que 36 e 24% tinham um ceo-d maior que 0 e 4, respectivamente. Notou-se que 72% das crianças eram alimentadas ao seio, 17% apenas com mamadeira e 10% pelos dois meios. Das crianças alimentadas apenas com mamadeira 70% apresentaram cárie. A cárie de mamadeira foi observada em 20% das crianças, sendo que 77% destas tinham sido alimentadas por mais de 12 meses. As crianças, cujos pais eram profissionais com terceiro grau de escolaridade, tiveram significativamente menos cárie do que aquelas de pais com nível técnico ou pais operários. A prevalência de cárie na faixa etária estudada foi relativamente alta. As crianças com cárie de mamadeira tenderam a manter seus hábitos de aleitamento por mais de 12 meses, sendo que o uso de mamadeira açucarada estava presente em 100% dos casos.
