Influences on the quality of preschool children's diets
Influences on the diet quality of preschool children: importance of maternal psychological characteristics Dr Megan Jarman PhD ANutr (Public Health) MRC Lifecourse Epidemiology Unit NIHR Southampton Nutrition Biomedical Research Centre [email protected] Background Quality of childrens diet is integral to optimal growth, development and lifelong health Poor quality diets are common among children aged 1.5-4.5 years and improving diet quality of preschool children is an important area for investment (Scientific Advisory Committee on Nutrition) Maternal, child and home food environment characteristics have been identified as important influences on childrens quality of diet but these are often studied in isolation Maternal psychological factors General control I think that what happens in my life is Research question:
often determined by factors within my control General self-efficacy I can overcome challenges in my life Do maternal psychological profiles predict childrens quality Self-efficacy for healthy of diet? Food involvement I enjoy cooking for others and myself eating I can overcome barriers to having a healthy diet Well-being I feel cheerful and in good spirits
Methods Mothers taking part in the Southampton Initiative for Health, with a 2-5 year old, were invited to complete a survey A questionnaire was used to collect information on childs quality of diet, characteristics and the home and mealtime environment Information about the mother was available from her participation in the Southampton Initiative for Health Quality of diet score Good quality (high score) Poor quality (low score) Maternal and child characteristics N 348 Children characteristics Age Gender Boys Girls Number of children in the house 1 2 3

Results 1 Percentage of mothers with scores above the median for psychological factors according to cluster membership
Cluster 1 = more resilient Cluster 2 = less resilient *difference in proportion is significant (p=<0.001) Results 2 Characteristic More resilient Less resilient P Value Mothers with university level education (n(%)) 63 (31) 19 (15) <0.001b More than 3 children in the house (n(%)) 33 (16)

consume meals (4 categories) Frequency of child eating meals in front of the television (4 categories) Childs average daily screen-time (hours) Summary Mothers who are less resilient tend to manage their childrens mealtime environments differently and have children with poorer quality diets than mothers who are more resilient These factors are more common in women disadvantaged by lower educational attainment Interventions to improve childrens quality of diet need to support women to manage their childrens eating habits and mealtime environments in a way that makes them feel more in control Thanks goes to The women who took part in our surveys and focus groups.
