Background To date, the vast majority of studies on infant feeding behavior of Chinese population have been conducted in Asian and some western countries but not the U.S. As the fastest growing Asian subgroup and with the largest Chinese community outside of Asia, studies that focus on their health choices in the U.S. are long overdue. Where studies are available, the overseas Chinese population is often regarded as high formula feeding and low breastfeeding. Chinese mothers often cite family, cultural, and social expectations as the determining factors for their choice of infant feeding. Given the cultural beliefs and traditions of Chinese immigrant population in the U.S., this study argues for the importance of including the input of the overall community, as opposed to only mothers, as a more data-based explanation of the prevalence of formula feeding among the Chinese community in New York City, and in addition, why this community continues to accept formula feeding as the norm. Methods Guided by Theory of Planned Behavior, this study incorporated both quantitative and qualitative components. A total of 434 surveys and 20 in-person interviews were collected in Chinese populated areas in New York City. Results In examining the prevalence of formula feeding in the Chinese community, both quantitative and qualitative findings consistently identified the central role friends and family played in motivating certain groups to use formula. These less acculturated, educated, and China-born subgroups are likely to conform to the idea that breast milk supplemented by infant formula is necessary in order to meet the nutritional demand of a growing infant. For the first-generation immigrants who breastfeed for health benefits and tradition, their attitudes towards infant feeding shifted after seeing other formula-fed children in populated Chinese communities as evident by shorter breastfeeding durations for the child born in the U.S. as compared to previous child born in China. As for the second-generation, who are more acculturated and educated, although they are aware of the benefits of breastfeeding and intend to breastfeed, they are expected by the older generation to continue the formula feeding tradition in the family. Conclusion When investigating why infant formula remained as the popular choice of feeding and is often perceived as the norm by this community, the current study identified the psychosocial variables that motivated individual subgroups and the context underlay. The findings provided new insights to the current literature and are intended to help guide future studies and to develop educational policy interventions to improve the overall infant feeding experiences for the Chinese community in New York City.

Our objective was to study the effect of GLN supplementation on whole body protein turnover, somatic growth and gastrointestinal tolerance to enteral feeding in neonates following surgical stress. We hypothesized that GLN in total parenteral nutrition (TPN) would (1) favor retention of lean body mass by reducing protein breakdown (PB) during the acute phase after surgery, (2) promote somatic growth, (3) decrease length of time to achieve full feeds. Protein turnover was measured in a double-blind randomized trial involving neonates admitted to the Neonatal Intensive Care Unit after major surgery. L-GLN (n = 6) was added to TPN at a dose of 200 mg/g of protein intake. Controls (n = 7) were isonitrogenous. Isotope studies were performed on Day 4 of TPN. Subjects were given a 4-hour primed constant intravenous infusion of L-[1-13C]-leucine and [15N2]-urea. In the GLN group, a 15% reduction in PB was measured (unpaired t-test, p < 0.05). There was a trend towards improved net protein balance which was statistically different from zero in the GLN group. There were no differences in somatic growth during TPN course and in the length of time to achieve full enteral feeds. Results suggest that early TPN supplemented with GLN has a beneficial sparing effect on protein metabolism in critically ill neonates after major surgical stress.

The objective of this randomized, double-blind, placebo-controlled trial was to determine whether glucose enhanced memory for a repeated auditory stimulus in human newborns. Infants consumed water or glucose (2-g/kg) solution. Memory test phases were: Orientation (turning towards the stimulus); Habituation (not turning towards), indicating familiarity; Delay (100 seconds); Spontaneous Recovery (stimulus representation: not turning towards indicates remembering, while turning towards indicates forgetting), and Novelty (turning towards a different word confirms wakefulness). Decreased head-turning towards during Spontaneous Recovery indicates enhanced memory. Blood glucose levels were measured after testing. / "Glucose" infants had higher blood glucose levels than "water" infants (p < 0.001). "Glucose" infants had significantly decreased turns towards during Spontaneous Recovery compared to "water" infants (p = 0.008), indicating memory enhancement. / Therefore, glucose specifically enhances memory for a repeated auditory stimulus in newborn humans. Elevating blood glucose levels by approximately 2 mmol/L appears to be sufficient for memory enhancement in healthy newborns.

Breastfeeding is the optimal form of infant feeding. It appears to protect children from certain childhood diseases that are over represented in the Aboriginal population. Although breastfeeding rates in the general Canadian population have increased over the past two decades, they remain lower than recommended. Rates in the Canadian Aboriginal population are even lower. Breastfeeding literature among Aboriginals is largely demographic and statistical in nature and focuses primarily on First Nations women living on reserves. The purpose of this study was to investigate the factors influencing the infant feeding decisions of Aboriginal women living in Saskatoon. Data were collected using qualitative methods, including face-to-face interviews and prolonged observation. Between October 2003 and May 2004, interviews were conducted with a total of eight participants recruited from the Food for Thought program in Saskatoon. A semi-structured prenatal interview was followed by two unstructured, in-depth interviews at approximately one month postpartum. The researcher's participation in two weekly Food for Thought sessions over the same time period allowed for prolonged observation. Observations were recorded using field notes and interviews were tape-recorded and transcribed verbatim. Observation and interview data from each participant were analyzed separately for dominant themes and then integrated to establish collective influencing factors. Results indicated influencing factors are numerous and varied in nature. Contextual (sociocultural and environmental), attitudinal, cognitive (knowledge, information and beliefs), experiential (previous infant feeding experiences), and psychological influences were revealed. The principle implication of this study for those involved with the protection, support, and promotion of breastfeeding in this population is that there are many factors capable of influencing feeding decisions. Feeding decisions are not static; they are dynamic and result from the complex interplay between influencing factors. The importance or significance of any single factor is a reflection of the circumstances surrounding the particular feeding decision.

Thesis (MNutr (Human Nutrition))--University of Stellenbosch, 2006. / Objective: To identify the reasons why high socio-economic class women in the Cape Metropole decide not to breastfeed; to identify the factors that influence the decision-making process when deciding which infant formula to feed the infant aged 0–6 months of age and to evaluate whether the type and volume of infant formula selected by the mother is appropriate for the infant’s needs. Method: The study was conducted as an observational descriptive study and consecutive sampling was used. Data was collected by means of a self-administered questionnaire that was available both in Afrikaans and English. Both open and closed ended questions were included. A Likert scale comprising four possible answers was used to determine attitude. Results: A total of 55 utilizable questionnaires were obtained. The majority of the mothers decided only after the birth of their infant to rather opt for formula feeding. Evident factors that were identified as a barrier to breastfeeding include a lack of knowledge and experience as well as a lack of facilities at public places and at work to breastfeed. Perceived benefits of infant formula included that the father could help with the workload and thus the father does not feel left out if the mother is breastfeeding, the mother knows what volume of infant formula the infant receives and it is more convenient if she is working. The mothers were overall not concerned about possible side effects of breastfeeding e.g. leaking and engorgement and did not feel that their breasts were physically not of optimal physiology e.g. too small or too large to be able to breastfeed. Conclusion: Numerous internal as well as external factors influence high socio-economic class women in the Cape Metropole when they decide whether to breastfeed or formula feed their infants. The identified barriers to breastfeeding will have to be addressed in this population in order to reach the WHO/UNICEF recommendation of exclusive breastfeeding up to the age of 6 months, and thereafter breastfeeding up to 2 years of age with the introduction of appropriate complementary foods.
