BACKGROUND Body size attitudes and body image form early in life, and understanding the factors that may be related to the development of such attitudes is important to design effective body dissatisfaction and disordered eating prevention interventions. This study explored how fathers' and mothers' body size attitudes, body dissatisfaction, and dietary(More)
Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3-year-old children and their parents, who provided data at baseline and 1 year later. Parents completed self-report body size attitude and dieting measures. Child weight(More)
Dieting is a risk factor for the development of eating disorders , and research suggests that dietary restraint emerges from a young age. There is a need to understand factors associated with the development of dieting intentions to prevent later disordered eating. The aim of this research was to explore individual and sociocultural factors related to(More)
Relationships between the body size attitudes of fathers and mothers and those of their four-year-old sons and daughters Despite evidence that parents can influence the development of body dissatisfaction and disordered eating in older children and adolescents, few studies have examined relationships between parents' body size attitudes and related(More)
School-based body image interventions for girls have typically been evaluated in single-sex rather than coeducational settings. However, there may be advantages to including boys within classes and it might also be more practical to deliver interventions to coeducational classes. Hence, it is important to examine any difference in outcomes between these two(More)
Very little is known about the development of body size attitudes in young children. We examined weight attitudes in 279 4-year-old girls and boys to test the hypothesis that children hold stereotypical beliefs about others based on body size, and that both child and maternal body image variables are related to these attitudes. Children completed an(More)
The role of serotonergic pathways in the hypnotic response to dexmedetomidine was examined in neurochemical and behavioral studies. Following acute administration of dexmedetomidine, loss of righting reflex and changes in serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine turnover in different brain regions (locus coeruleus and hippocampus) were(More)
We measured the concentrations of alpha-melanocyte-stimulating hormone (alpha-MSH) in various brain regions as well as in the pituitary gland and plasma of the toad Bufo speciosus during a 24-hr light:dark cycle. There was significant diurnal variation of alpha-MSH concentrations in the hypothalamus and brainstem. In both areas alpha-MSH concentrations were(More)
We investigated the potential influence of opioid and melanotropic peptides on endogenous norepinephrine (NE) release from the A2 noradrenergic cell group of rats using a static, fixed-volume incubation procedure. Norepinephrine release from slices of caudal dorsomedial medulla (CDMM) was evoked by high potassium concentrations (20 and 60 mM) in a(More)
