We evaluated breast-feeding and complementary feeding practices in Mexico, using data from a national probabilistic survey carried out in 17,716 households, with regional and urban-rural representation. Mothers of children <2 y old (n = 3,191) reported duration of breast-feeding and the ages of usual introduction of 7 food groups. The Kaplan-Meier method was used to estimate the median time of ...

Data were prospectively obtained from exclusively breast-fed healthy term neonates at birth and from healthy mothers with no obstetric complication to determine risk factors for excess weight loss and hypernatremia in exclusively breast-fed infants. Thirty-four neonates with a weight loss > or = 10% were diagnosed between April 2001 and January 2005. Six of 18 infants who were eligible for the ...

The first two years of life are the most vital in a child’s growth and development. The nutrition provided during this phase of life, lays the foundation of health and healthy feeding habits. Poor feeding practices during 0-5 years, resulting in malnutrition, contribute to impaired cognitive and social development, and reduced productivity in later life. Research studies were clearly provided t...

This paper summarizes findings from a formative research study conducted in Haiti to develop a behavior change communication (BCC) strategy to improve infant and child feeding practices and to reduce childhood malnutrition. It describes the methodology used and the tools developed to facilitate decisionmaking and effective use of formative research for program planning. The study is part of a l...

Cross-feeding, a relationship wherein one organism consumes metabolites excreted by another, is a ubiquitous feature of natural and clinically-relevant microbial communities and could be a key factor promoting diversity in extreme and/or nutrient-poor environments. However, it remains unclear how readily cross-feeding interactions form, and therefore our ability to predict their emergence is li...

Wood-feeding insects encounter challenging diets containing low protein quantities, recalcitrant carbohydrate sources, and plant defensive compounds. The Asian longhorned beetle (Anoplophora glabripennis) is a wood-feeding insect that attacks and kills a diversity of hardwood tree species. We compared gene expression of midguts collected from larvae feeding in a preferred tree, sugar maple, to ...

The onset of feeding at birth is a vital step for the adaptation of the neonate to extra uterine life. Prader-Willi syndrome (PWS) is a complex neurogenetic disorder caused by the alteration of several imprinted contiguous genes including MAGEL2. PWS presents with various clinical manifestations, including poor suckling behaviour and feeding problems in neonates. Hypothalamic defects have been ...

Feeding performance studies can address questions relevant to feeding ecology and evolution. Our current understanding of feeding mechanisms for aquatic mammals is poor. Therefore, we characterized the feeding kinematics and performance of five Steller sea lions (Eumetopias jubatus) and six northern fur seals (Callorhinus ursinus). We tested the hypotheses that both species use suction as their...

OBJECTIVE To determine the relationship between pacifier use and the duration of exclusive breast-feeding in the first six months of age, among poor children with unfavourable birth weight, from an underdeveloped region in Brazil. METHOD Prospective cohort study with infants followed from birth to 6 months of age. Healthy children born with unfavourable birth weight (<3,000), being exclusivel...
