A significantly high number of patients with anorexia nervosa are overweight immediately before the onset of the condition. This premorbid weight may be a feature of their constitution but is sometimes a more transitory phenomenon. Menstruation ceases early in the condition but usually within the context of significant weight loss. However, the subsequent amenorrhoea, related to factors that pr...

The modern world is saturated with highly palatable and highly available food, providing many opportunities to associate food with environmental cues and actions (through Pavlovian and operant or instrumental learning, respectively). Basic learning processes can often increase the tendency to approach and consume food, whereas extinction, in which Pavlovian and operant behaviors decline when th...

While shark-based tourism is a rapidly growing global industry, there is ongoing controversy about the effects of provisioning on the target species. This study investigated the effect of feeding on whale sharks (Rhincodon typus) at a provisioning site in Oslob, Cebu, in terms of arrival time, avoidance and feeding behaviour using photo-identification and focal follows. Additionally, compliance...

BACKGROUND Despite the importance of early initiation of and exclusive breastfeeding, prelacteal feeds continue to pose a barrier to optimal breastfeeding practices in several countries, including Vietnam. This study examined the factors associated with prelacteal feeding among Vietnamese mothers. METHODS Data from 6068 mother-child (<6 m) dyads were obtained from a cross-sectional survey con...

The feeding biology of eight species of benthivorous fishes was studied in a sandy shore at Anchieta Island, south-eastern Brazilian coast. The fishes fed mainly on Amphipoda and Mysidacea crustaceans. The diet of the most abundant species, the drum Umbrina coroides, was analyzed in three standard length classes (20-55, 56-90 and 91-135 mm). This sciaenid showed an ontogenetic diet shift from M...

STUDY OBJECTIVES The main aim of the study was to discover if a midwife home visiting programme has a significant effect on the prevalence of health problems and breast feeding behaviour of mothers who delivered normally and their healthy fullterm newborn babies, during a period of 42 days after delivery. Another aim was to compare the mothers', the midwife's, and the doctor's findings of preva...

BACKGROUND Breastfeeding has numerous health benefits. In 2010, the province of Newfoundland and Labrador had the lowest breastfeeding initiation rate (64.0%) in Canada. Formula feeding is associated with well-known health risks. Exclusive formula feeding is the "cultural norm" in some regions of the province. Women appear resistant to changing their infant feeding behaviors and remain committe...

The study of human appetite and eating behaviour has become increasingly important in recent years due to the rise in body weight dysregulation through both obesity and eating disorders. Adequate control over appetite is paramount for the control of body weight and in order to understand appetite, it is necessary to measure eating behaviour accurately. So far, research in this field has reveale...

BACKGROUND Exclusive breastfeeding until six months followed by the introduction of solids and continued breastfeeding is recommended by the World Health Organisation. The dominant approach to achieving this has been to educate and support women to start and continue breastfeeding rather than understanding behaviour change processes from a broader perspective. METHOD Serial qualitative interv...

Feeding is an important factor for the successful rearing of larvae of the crab species. Further information on the morphological features of the foregut may to reveal larval feeding behaviour and or/whether there is a lecithotrophy in some or even in all stages of the larval cycle. In the present study, the structural development of the foregut and their digestive functions were examined in la...
