Abstract Maternal lactational investment can affect female reproductive rates and offspring survival in mammals be biased towards infants of one sex. We compared estimates lactation effort among mothers, assessed as their potential milk contribution to age-specific infant diets (mother-infant differences fecal stable nitrogen isotopes, δ 15 N), the timing weaning (infant age at last nursing bou...

The onset of walking is a developmental transition that sets in motion a cascade of change across a range of domains, including social interactions and language learning. However, research on the unfolding of such change in the infant across this transition is limited. This investigation utilized a longitudinal design to examine the effect of walking acquisition on infant social development and...

In two short-term longitudinal studies, infant expressivity and maternal responsiveness to infant expressivity were examined. In Study 1, thirty-eight dyads visited a laboratory at 11 and 12 months; in Study 2, seventy-seven dyads were visited in their homes at 9 and 13 months. Mother-infant interaction was coded from videotapes of free play in both studies. Infant expressivity and maternal res...

Background The provision, maintenance and promotion of the health of infants as a vulnerable group in health care services are a high priority, and the first step in reducing infant mortality and improving their health is undoubtedly the identification of their mortality status. We aimed to study the spatial distribution of premature infant mortality in 194 count...

Objective: This analytical, cross-sectional study was designed to determine the effect of postpartum depression in mothers with 0–1 year old infant on father–infant attachment.Methods: The included 207 and fathers 0–12-month-old infants. data were collected using Introductory Information Form, Edinburgh Postpartum Depression Scale (EPDS), Father–Infant Attachment (FIAS). analyzed standard devia...

Determination of drug residues in food is of great importance due to their toxicity. Long-term exposure with low level of drug residues could be important, especially in children. Based on document study, oxytetracycline (OTC) is a prophylaxis and treatment agent for great number of diseases and possesses a broad spectrum activity against many pathogenic organisms and can be toxic or cause alle...

 Background: Having an infant in the neonatal intensive care unit (NICU) is a stressful and painful experience. Unlike to normal births, this birth is associated with admission and separation of infant from parents. The aim of this study was to compile the supporting-emotional needs of Iranian parents who have a premature infant admitted in (NICU). Methods: This study was performed using qualit...

KEY FINDINGS Data from the Linked Birth/Infant Death Data Set and Preliminary Mortality Data File, National Vital Statistics System. The U.S. infant mortality rate did not decline from 2000 to 2005. Data from the preliminary mortality file suggest a 2% decline in the infant mortality rate from 2005 to 2006. The U.S. infant mortality rate is higher than those in most other developed countries, a...
