Feeding, artificial sucking habits, and malocclusions in 3-year-old girls in different regions of the world.

PURPOSE: The way babies and young children are reared is important to their health and development. Extensive breast-feeding has also been shown to reduce the development of artificial sucking habits like digit or pacifier-sucking. The aim of this study was to determine feeding methods, artificial sucking habits, and the presence of malocclusions in 3-year-old girls living in different regions of the world. METHODS: Children from the following countries were involved in the present study: (1) Brazil (Porto Alegre); (2) Japan (Niigata); (3) Mexico (Mexico City); (4) Norway (Oslo); (5) Sweden (Falköping); (6) Turkey (Istanbul); (7) and the United States (Iowa City, Iowa). During the interview and examination, the following variables were evaluated and registered: (1) breastfeeding and bottle-feeding; (2) duration and frequency; (3) sucking habits; (4) posterior and anterior crossbites; and (5) other malocclusions/normal occlusion. RESULTS: The prevalence of breast-feeding was very high in all groups, ranging between 78% and 98%. The prevalence of bottle-feeding in the different areas was also high. Except for Iowa City, the prevalence of digit-sucking was relatively low. Pacifier-sucking is fairly popular in most areas, with the exception of Niigata. The prevalence of normal occlusion in different cities ranged from 38% to 98%. CONCLUSIONS: There are considerable differences in feeding, as well as artificial sucking habits, in different areas of the world and at different periods.

A review of viruses affecting raptors.

Outbreaks of viral diseases have been diagnosed more commonly in raptors in recent years. The practice of feeding carnivorous birds with food derived from other birds exposes them directly to a wide range of potential pathogens. Some viruses which are avirulent in their natural host are known to be more pathogenic when they cross the species barrier. Compromised immunity due to stress or inbreeding may further increase the disease risk. Traditional feeding methods may need to be re-appraised and changed in view of this risk. This paper reviews the literature on viral diseases of raptors and provides additional clinicopathological observations from unpublished cases.

Breast-feeding and its relation to smoking and mode of delivery.

OBJECTIVE: To examine the effects of cesarean and forceps or vacuum delivery and parental smoking habits on the initiation and duration of breast-feeding. METHODS: We conducted a prospective, population-based birth cohort study in 1997. Data were collected on breast-feeding history, household smoking habits, method of delivery, and other demographic, obstetric, behavioral, and potential confounding variables via a standardized self-administered questionnaire. Multivariable logistic regression was used to examine the association between method of birth (cesarean versus forceps or vacuum delivery versus normal vaginal birth) and either not initiating breast-feeding or doing so for less than 1 month. Among women who breast-fed for 1 month or more, multivariable survival analysis was employed to study the relationship between method of delivery and breast-feeding duration. We repeated these analyses to examine the link between parental smoking habits and breast-feeding initiation and duration. RESULTS: A total of 7825 mother-infant pairs were followed up for 9 months. Cesarean delivery was a risk factor for not initiating breast-feeding, for breast-feeding less than 1 month, and remained a significant hazard against breast-feeding duration. Assisted delivery with forceps or vacuum, although not associated with breast-feeding initiation, was a significant risk against breast-feeding duration. Conversely, current parental smoking habits only affected breast-feeding initiation but were unrelated to breast-feeding duration. CONCLUSION: This study indicates a possible effect of forceps or vacuum delivery on breast-feeding and of cesarean on long-term breast-feeding duration. The findings provide additional evidence in support of the avoidance of unnecessary obstetric interventions.

Hospital infant formula discharge packages. Do they affect the duration of breast-feeding?

OBJECTIVE: To determine whether the duration of breast-feeding is affected by the contents of the hospital discharge package. DESIGN: A randomized clinical trial with 2 experimental interventions (a discharge package containing a manual breast pump only and a discharge package containing a commercially prepared infant formula and a manual breast pump) and a control group who received a commercially prepared infant formula discharge package only. Sociodemographic characteristics and information concerning prior births (including feeding methods) were obtained from each mother within 48 hours of her infant's birth. Sources of influence on the mother's feeding decision, maternal attitudes concerning breast-feeding, and maternal feeding preferences were also assessed. PARTICIPANTS: The sample consisted of 763 women who had given birth who were admitted to the maternal-fetal unit of a midwestern community hospital. MAIN OUTCOME MEASURES: Information concerning current method of infant feeding was obtained from telephone interviews conducted at 2-week intervals until the infant was 16 weeks old. The data were analyzed using descriptive statistics, multivariate analysis of variance, logistic regression analysis, and survival analysis. RESULTS: The content of the hospital discharge package did not affect whether the mother engaged in exclusive or partial breast-feeding during the 16-week follow-up interval. However, there was some evidence that providing formula samples at discharge from the hospital increased the duration of exclusive breast-feeding compared with providing a manual breast pump. CONCLUSION: This study does not support the assumption that inclusion of infant formula in hospital discharge packages decreases the duration of breast-feeding.

[Evaluation of child-rearing environmental factors that affect the occurrence of sudden infant death syndrome: interview conducted by public health nurses].

PURPOSE: We examined the child-rearing environmental factors that affect the occurrence of sudden infant death syndrome (SIDS) by using a nation-wide survey. METHOD: Infants who died due to SIDS between January 1996 and June 1997 in Japan were identified from death certificates. Controls of the same sex, birthplace, and birth months as the corresponding SIDS were chosen from birth certificates. Interviews of both cases and controls were undergone in January and February 1998 by public health nurses. RESULTS: The following Child-rearing factors exhibited a significant relationship with the occurrence of SIDS: 1. Concerning the sleeping position, the prone position was associated with increased risk compared to the supine position, with an odds ratio of 3.02 (95% c.i. 2.07-4.65). 2. Regarding the feeding method, artificial feeding only demonstrated a higher risk than breast feeding only, with an odds ratio of 4.92 (95% c.i. 2.78-9.63). 3. With regard to smoking, infants with both parents who smoked exhibited a higher risk than infants where neither parents smoked, with an odds ratio of 3.50 (95% c.i. 1.74-8.32).

Personal preferences and ethnic variations among Anglo and Hispanic breast and bottle feeders.

The preferences of Spanish-speaking Hispanics and English-speaking Anglos for breast and bottle feeding were evaluated using marketing research techniques. Preliminary interviews with 55 mothers conducted within the first 48 hr post-partum elicited a list of verbatim responses regarding the positive and negative aspects of both feeding methods. An additional 195 women rank-ordered the most frequently mentioned statements in terms of their preference for each. Socio-demographic data on the mothers were analyzed with chi-square analysis and discriminant analysis. Multidimensional scaling was used to assess the preferred characteristics of breast and bottle feeding. Results indicated that most mothers prefer a method of infant feeding that allows the mother to be 'closer to her baby' and allows the baby to 'grow up healthier.' Bottle feeders perceived bottle feeding to be superior because it insured that baby would be 'full and satisfied' and would 'get all the vitamins and nutrients it needed,' especially when 'mother was not eating right" or was 'on medications.' Analysis of cultural preference patterns revealed that there exists a strong culture pattern or preference for breast feeding and its characteristics among Anglos. In contrast, the Hispanics show no clear preference for either breast or bottle feeding.

Bacitracin determination in feeds: evaluation of methods.

Assay of bacitracin activity in feeds is subject to many sources of variation. Bacitracin standards are complex mixtures and may contain various amounts of less active forms of bacitracin. Test organisms may respond differently to these mixtures. Collaborative studies should involve the use of one standard, perhaps USP zinc bacitracin. The use of different types of bacitracin standards (regular or zinc) in a laboratory may contribute to variation in sample potency. The pyridine extraction method is subject to serious operational difficulties. Among the contributing factors are incomplete evaporation of pyridine (causing positive bias), allowing the temperature to increase too much during evaporation (causing negative bias), and the numerous manipulative steps in the technique (causing large variability). Because of these factors and the toxic properties of pyridine, the method finds little use. Methanol extraction offers a better substitute for determining zinc or methylene disalicylate bacitracin in premixes and complete feeds by the plate method.

Breast feeding on campus: personal experiences, beliefs, and attitudes of the university community.

Breast feeding a new baby is a special challenge for college students and university employees. Although success is usually associated with availability of support from the community, little is known about the social context for breast feeding on campus. Personal breast feeding experiences, beliefs about outcomes of breast-feeding and bottle feeding, attitudes toward breast feeding and bottle feeding, and regard for appropriateness of various settings for breast feeding in the campus community were investigated. One hundred seven students, faculty, staff, and administrators at a North Central state university participated in the study. Almost all reported at least one personal breast-feeding experience. Benefits of breast feeding over bottle feeding were acknowledged; however, the university community regarded both feeding methods favorably and saw practical advantages to bottle feeding. Personal spaces, such as infant home or family car, were regarded as more appropriate for breast feeding than public settings. Implications for promotion, support, and protection of breast feeding on campus are discussed.

The role of the nurse in support of breast feeding.

The nurse can provide information about, and support of, breast feeding. The prenatal nurse can inform the mother of the advantages of breast feeding to herself and her baby. The labour and delivery nurse can aid the mother in her first contact with the baby and reassure the mother who has a Caesarean birth, or a premature or sick infant, that she too can nurse. The postpartum nurse can help breast feeding to continue by providing frequent maternal-infant contact during the mother's hospital stay. The nursery nurse supports breast feeding by refraining from giving the baby other fluids. The paediatric nurse continues the helping pattern by reinforcing the statements and actions of others which will further impress the mother with the appropriateness of her infant feeding method. Mothers need to be informed about infant feeding options in order to make a knowledgeable choice based on awareness of alternatives. The nurse's role in support of breast feeding varies with the time and place where patient care is provided. In each setting, however, the nurse plays a significant role in helping the mother to begin breast feeding and to enjoy it, at the same time providing her infant with optimum nutrition for his early growth and development.

The influence of reported paternal attitudes on the decision to breast-feed.

OBJECTIVE: To identify factors that influence a woman's decision to breast-feed. METHODOLOGY: Five hundred and fifty-six women were recruited from the maternity wards of two Perth hospitals. Data were collected from a self-administered questionnaire completed by participants prior to discharge. Logistic regression analysis was used to determine factors influencing the initiation of breast-feeding. RESULTS: At discharge from hospital 83.8% of women were breast-feeding, including 6% who were giving complementary formula feeds. After controlling for potentially confounding demographic and biomedical factors, the father's reported preference for breast-feeding was found to be the most important factor influencing a woman's decision to breast-feed (OR 10.18). CONCLUSION: Fathers participate in and influence the choice of infant feeding method and should be included in breast-feeding discussions.

Breast feeding and cognitive development at age 1 and 5 years.

AIM: To examine whether duration of breast feeding has any effect on a child's cognitive or motor development in a population with favourable environmental conditions and a high prevalence of breast feeding. METHODS: In 345 Scandinavian children, data on breast feeding were prospectively recorded during the first year of life, and neuromotor development was assessed at 1 and 5 years of age. Main outcome measures were Bayley's Scales of Infant Development at age 13 months (Mental Index, MDI; Psychomotor Index, PDI), Wechsler Preschool and Primary Scales of Intelligence (WPPSI-R), and Peabody Developmental Scales at age 5. RESULTS: Children breast fed for less than 3 months had an increased risk, compared to children breast fed for at least 6 months, of a test score below the median value of MDI at 13 months and of WPPSI-R at 5 years. Maternal age, maternal intelligence (Raven score), maternal education, and smoking in pregnancy were significant confounders, but the increased risk of lower MDI and total IQ scores persisted after adjustment for each of these factors. We found no clear association between duration of breast feeding and motor development at 13 months or 5 years of age. CONCLUSION: Our data suggest that a longer duration of breast feeding benefits cognitive development.

Monitoring bolus nasogastric tube feeding by the Brix value determination and residual volume measurement of gastric contents.

BACKGROUND: Critically ill patients do not always tolerate nasogastric tube feeding. Gastric residual volumes (GRVs), obtained by aspiration from a nasogastric tube, are widely used to evaluate feeding tolerance and gastric emptying, but controversy exists about what constitutes the true GRV (diet formula or digestive juice) and how it should affect management. In this pilot study, we used the Brix value (BV) measurement of gastric contents to monitor both GRV and food content in patients receiving nasogastric feeding. METHODS: Forty-three patients receiving bolus nasogastric feeding were monitored for 24 hours before entry into the study and then divided into 2 groups according to traditional use of GRV; patients with low GRVs (< 75 mL) were placed in group 1, whereas patients with higher GRVs (> 75 mL) were placed in group 2. All subjects were given 250 mL of polymeric formula by bolus nasogastric infusion, followed by BV measurement of gastric contents at 0, 30, 60, 120, and 180 minutes. All gastric fluid was aspirated after 180 minutes of feeding; the volume was recorded and BV measurement made, then reinstilled with an added 30 mL of dilutional water, after which a final aspiration and BV measurement was performed. Calculated GRV and volume of formula remaining in the stomach was determined by derived equations. RESULTS: Serial BV measurements decreased in both groups after bolus feeding. For patients in group 2, the decrease was less such that at 180 minutes, the mean BV for gastric contents was significantly higher than for those patients in group 1 (10.1 vs 5.1, respectively; p < .01). Aspirated GRV, calculated GRV, and volume of formula remaining in the stomach at 180 minutes were significantly greater for patients in group 2 compared with those in group 1. Use of refractometry in combination with traditional use of GRV identified 4% (1/25) of patients in group 1 with low GRVs who might have possible gastric dysmotility (> 20% of initial 250-mL volume of formula remaining at 180 minutes) and ensured that 72% (13/18) of patients in group 2 with higher GRVs had sufficient gastric emptying (< 20% of initial 250 mL volume of formula remaining). CONCLUSION: This pilot study raises the feasibility that refractometry and the BV measurement of gastric juice may be a promising tool for bedside monitoring of tolerance and gastric emptying in patients receiving nasogastric feeding, providing valuable complementary information to traditional use of GRV.

The effect of breast- and bottle-feeding on oxygen saturation and body temperature in preterm infants.

From July 1997 to June 1998, 25 preterm infants (birth weight < 1800 g) were included in a prospective study to compare the clinical effects of breast- and bottle-feeding. Oxygen saturation, heart rate, respiratory rate, and body temperature were recorded every minute for 20 minutes during feeding periods. Eighty pairs of breast- and bottle-feeding sessions were observed at the chronological age of 9.3 +/- 4.3 (range = 2.1-25.3) weeks. Oxygen saturation and body temperature of the preterm infants were significantly higher when they were directly breastfed. There were 2 episodes of apnea (breath pause more than 20 seconds) and 20 episodes of oxygen desaturation (PaO2 < 90%) during bottle-feeding and none during breastfeeding. We conclude that breastfeeding is a more physiological feeding method for the preterm infant and bottle-feeding may be more stressful.

A decrease in mother-to-child transmission of human T lymphotropic virus type I (HTLV-I) in Okinawa, Japan.

To investigate the chronologic change of mother-to-child transmission of human T lymphotropic virus type I (HTLV-I) in Okinawa, Japan, the presence of antibody to HTLV-I was tested in 4,187 healthy residents between, 4,528 nursery school children, and 3,837 pregnant women between 1968 and 2000. The chronologic change of the feeding method and the length of the breast-feeding period among 1,117 healthy mothers from 1937 to 1995 were also obtained by interview. Age-adjusted prevalence of HTLV-I among healthy residents decreased from 9.1% in 1968-1970 to 7.8% in 1981-1984 and to 6.3% in 1996-1998. The crude prevalence of antibody to HTLV-I among healthy residents less than 20 years old decreased significantly from 4.6% in 1968-1970 to 0.1% in 1996-1998 (P < 0.0001). The prevalence of antibody to HTLV-I among nursery school children decreased significantly over the study period, from a high of 1.8% in 1984 to a low of 0.2% in 1998 (P = 0.03). The prevalence among pregnant women decreased significantly from 5.6% in 1989-1992 to 3.7% in 1997-2000 (P = 0.0275). Prior to 1967, all healthy mothers breast-fed their children. After 1968, the use of bottled and mixed milk (breast milk and bottled milk) increased, with bottled milk becoming predominant after 1990 (89%). The percentage of healthy mothers breast-feeding for more than one year significantly decreased from 68.3% in 1937-1947 to 0.4% in 1990-1995 (P < 0.0001). Infection with HTLV-I in Okinawa has decreased mainly due to a reduction in the number of mothers breast-feeding and a shortening of the breast-feeding period. However, because the mother-to-child transmission rate among non-breast-feeders decreased from 12.8% in 1986-1991 to 3.2% in 1995-1999, there may be other factors involved in the decrease in mother-to-child transmission.

[Study on therapeutic effects of metformin on rat fatty livers induced by high fat feeding].

OBJECTIVES: To explore the therapeutic effects of metformin on rat fatty livers induced by high fat feeding. METHODS: A fatty liver model was established by feeding rats with a high caloric laboratory chow for 12 weeks, then the rats were randomly divided into three groups, i.e. model control group, metformin group and dietary treatment group. A normal control group was organized at the same time. The rats of the metformin group were given metformin 156 mg/kg/d while the other groups were given distilled water of the same volume by stomach feeding. The model control group rats were fed with high caloric laboratory chow while other groups were fed a normal diet. After four weeks, all the animals were sacrificed. Liver index (liver/body weight ratio), serum activities of liver-associated enzymes, blood lipids, liver triglycerides, fasting blood glucose, fasting plasma insulin, HOMA insulin resistance index (HOMA-IR), and the liver histology of rats of all groups were assayed. RESULTS: The body weight, liver index, serum activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), total cholesterol (TC), triglycerides (TG) and liver triglycerides in the model group increased significantly, while HDL-cholesterol concentration decreased significantly. Fasting blood glucose, fasting plasma insulin and HOMA-IR showed an increasing tendency, but there was no significant difference of those indexes among the three groups. The liver histology in the model group showed moderate to severe steatosis, mainly as macro vesicle steatosis, lobular inflammatory, cell infiltration and necrosis. Compared with the model group, the levels of body weight, liver index, serum ALT, ALP, TC, TG and liver triglycerides in the metformin group were significantly lower and were similar to those of the normal group, while their HDL-cholesterol concentration was significantly higher. The liver histology in the metformin group was nearly normal. In the dietary treatment group, hyperlipidemia persisted, although liver index and GGT were lower and the liver histology changes were somewhat milder. CONCLUSION: It is suggestive that metformin might be effective in treating rat fatty liver induced by high fat feeding.

A pilot study to assess the viability of a randomised controlled trial of methods of supplementary feeding of breast-fed pre-term babies.

OBJECTIVES: to compare the impact of two methods of supplementary feeding of pre-term babies (bottle vs cup) on subsequent breast feeding and to assess the feasibility of using a randomised controlled trial (RCT) to investigate the topic. DESIGN AND METHOD: small scale prospective RCT. Data on breast feeding, as defined as the exclusive method of feeding, were collected. A range of relevant bio-data was also collected and their impact on breast feeding assessed. SETTING: a special care baby unit in a District General Hospital in the UK. PARTICIPANTS: over a three-month period, all pre-term babies (32-37 weeks' gestation) who fulfilled the inclusion criteria and has been born to mothers who had expressed a pre-partum desire to breast feed, who had consented to take part, were included (n=14). PROCEDURE: the eligible babies were randomly allocated to supplementary feeding of breast milk, via either a cup or a bottle. Whether or not the baby was being breast fed at discharge was noted. FINDINGS: the study suggested that this RCT framework is a viable method of investigating baby feeding. Because of the small-scale nature of the project, the actual database must be treated with extreme caution. No significant differences were found between the two groups in terms of breast feeding. However, the mothers reported high levels of support and also the breast-feeding rates were above the national averages. These two findings could have contributed to the non-significant results observed in this analysis. CONCLUSIONS: if the present findings could be supported by further research, then the non-significant results relating method of supplementary feeds to subsequent breast feeding could be explained by reference to three factors. Firstly, there is, in fact, no real effect of method of supplementary feeding and subsequent breast feeding; secondly, the method adopted differed from existing research and thus may be expected to produce non-corroborative results; and finally, the overall levels of breast feeding within the Unit generally were higher than the national average. The relevance of the RCT for investigating this subject is also discussed with reference to the present data set. Further experimental work to develop these ideas and to identify causal links is required.

A feeding protocol for healthy preterm infants that shortens time to oral feeding.

OBJECTIVE: To test the hypothesis that healthy preterm infants randomly assigned to a semi-demand feeding protocol would require fewer days to attain oral feeding and have a satisfactory weight gain compared with control infants receiving standard care. STUDY DESIGN: In 2 neonatal intensive care nurseries, 81 infants 32 to < or = 34 weeks' postconceptional age were randomly assigned to the control (n = 41) or experimental (n = 40) protocol for transition from gavage to oral feedings. The control protocol followed the standard practice of gradually increasing scheduled oral feedings, whereas the experimental protocol used a semi-demand feeding method contingent on infant behavior. Analysis of variance techniques were used to compare the study groups for number of days to attain oral feeding and weight gain. RESULTS: The semi-demand method shortened the time for infants to achieve oral feeding by 5 days (P < .001). There were no differences in weight gain between the study groups, and both groups had satisfactory weight gain. CONCLUSION: The semi-demand method for the transition from gavage to oral feeding in healthy, preterm infants 32 to < or = 34 weeks postconceptional age promotes faster attainment of oral feeding and does not compromise their weight gain.

Who is breast-feeding? Implications of associated social and biomedical variables for research on the consequences of method of infant feeding.

The objective of this paper is to identify social and biomedical variables that influence the selection of methods of infant feeding in the United States and to provide guidelines for the choice of control variables in the design and interpretation of studies that examine the influence of breast-feeding on infant and child health. Data were drawn from a national household survey, the Child Health Supplement of the 1981 Health Interview Survey conducted by the National Center for Health Statistics. Relationships between demographic, socioeconomic, and health variables were studied for the total sample of children under age 5 y as well as for black and white women separately. The data provide evidence for the importance of both social and health variables as selection factors for breast-feeding in the United States.
