Interaction between feeding method and co-sleeping on maternal-newborn sleep.

BACKGROUND: Previous studies have demonstrated that breastfed newborns spend more time awake than bottle-fed newborns, breastfeeding mothers have more fragmented sleep than bottle-feeding mothers, and mother-newborn sleeping arrangements may affect the sleep/wake pattern of mother-newborn pairs. OBJECTIVE: To address the unsolved question of whether there is an interaction between type of feeding and sleeping arrangements that affects postpartum sleep during the 4th postpartum week. DESIGN: Correlational, two-way design using feeding method and location of newborn at night as independent variables, and sleep patterns as the dependent variables. SETTING: Patient's home during 4th week after giving birth. PATIENTS/PARTICIPANTS: First-time mothers and their newborns (n = 33). MAIN OUTCOME MEASURES: Amount of total sleep, amount of night sleep, number of night awakenings, and number of sleep periods in 24 hours using a modified version of the self-report sleep instrument by Barnard and Eyres. RESULTS: Breastfed newborns had less total sleep per day than bottle-fed newborns, and breastfeeding mothers had more sleep periods in 24 hours than bottle-feeding mothers. Breastfeeding mothers slept more than bottle-feeding mothers when co-sleeping, but bottle-feeding mothers' sleep was unaffected by location of newborn. Average total sleep for 4-week-old newborns was about 14 hours daily. CONCLUSIONS: More sleep was obtained when breastfeeding mothers slept with the newborn. Methods or devices that allow breastfeeding mothers and newborns to sleep next to each other in complete safety need to be developed.

Developmental issues and the choice of feeding method of adolescent mothers.

Approximately one million teenagers become pregnant each year, resulting in over 600,000 live births. An exploratory study was conducted to look at attitudes of adolescent mothers toward breastfeeding. Striking differences were found in the responses between groups of breastfeeding and bottlefeeding mothers. The effect of developmental needs and levels on the choice of feeding method was explored.

Feeding method and motor activity in 3-month-old human infants.

It is currently acknowledged that breast-fed and formula-fed infants exhibit different rates of physical growth. Little is known, however, about behavioral differences that may be attributable to early feeding method. In the present investigation, activity level in 3-mo.-old infants was examined by measuring motoric output in 40 breast-fed and 40 formula-fed infants. Maternal ratings of temperament did not differ across the two groups, but scores derived from the actometer in a laboratory setting showed breast-fed infants to be more active. Upper limb activity appeared to be particularly sensitive to feeding regimen. Possible explanations for this effect as well as implications of these results are discussed.

Incidence of Haemophilus influenzae in the throats of healthy infants with different feeding methods.

BACKGROUND: Haemophilus influenzae is the major cause of otitis media and lower respiratory tract infection in childhood. In the presence of human milk, which contains numerous host defense factors, Haemophilus influenzae may be inhibited in attaching to and colonizing pharyngeal cells. We investigated the incidence of H. influenzae in the throats of 162 healthy infants with different feeding methods: 70 breast-fed, 49 mixed-fed and 43 formula-fed infants. METHODS AND RESULTS: Haemophilus influenzae was identified using standard microbiological procedures and the API NH system. The incidence of H. influenzae in breast-fed infants, mixed-fed infants and formula-fed infants was 0, 0 and 7.0% respectively. CONCLUSION: The results suggest that the colonization of H. influenzae in the throat was inhibited by the presence of breast milk.

A prospective randomized trial of feeding methods in very low birth weight infants.

OBJECTIVE: To test the hypothesis that very low birth weight infants fed by continuous nasogastric gavage (CNG) would achieve full enteral feedings (100 kcal/kg/d) at an earlier postnatal age and have less feeding intolerance (FI) than infants fed by intermittent bolus gavage (IBG). METHODS: Eighty infants were stratified by birth weight (700 to 1000 g and 1001 to 1250 g) and randomized into CNG or IBG feeding groups. CNG infants were comparable with IBG in birth weight, gestational age, sex, race, and day of onset of feeding (5.7 +/- 2.1 days vs 5.6 +/- 2.2 days, respectively). Feedings were given as undiluted Similac Special Care formula (Ross Laboratories, Columbus, OH) via a specific protocol designed for each 50 to 100 g birth weight category. Feedings were advanced isoenergetically by a maximum of 25 mL/kg/d until an endpoint of 100/kcal/kg/d for at least 48 hours was reached. An infant whose feedings were withheld for >12 hours based on predetermined criteria was considered to have an episode of FI. RESULTS: Infants in the CNG group reached full enteral feeding at 17.1 +/- 8.9 days compared with 15.5 +/- 5.5 days in the IBG group; these were not statistically different. Secondary outcome variables such as days to regain birth weight (CNG, 12.6 +/- 5 days vs IBG, 12.5 +/- 3.7 days), days to reach discharge weight of 2040 g (CNG, 60 +/- 13.4 days vs IBG, 62 +/- 13.6 days), and number of episodes of FI were not significantly different between feeding methods. FI was primarily associated with birth weight </=1000 g (71%) vs 1001 to 1250 g (38%). CONCLUSION: Feeding methods are associated with similar outcomes when feeding regimens are comparable.

Sipping/lapping is a safe alternative feeding method to suckling for preterm infants.

AIM: To determine whether sipping/lapping is a safe alternative to suckle bottle-feeding without any hydrostatic pressure, in terms of physiological stability and the relationship between swallowing and respiration. In addition, tongue movement was compared between sipping/lapping and suckling (bottle- and breastfeeding). METHODS: Eighteen infants (30-35?wk of gestation at birth) were studied while sipping/lapping and suckling a bottle without any hydrostatic pressure at different feeding sessions on the same day of the first oral feeding. The postmenstrual age at the time of study was 34.6+/-0.2 wk. We evaluated the amounts ingested and administration times. The heart rate, O(2) saturation (SpO(2)), and relationship between swallowing and respiration were examined while feeding. Tongue movements were also observed by ultrasonography. Statistical analysis was performed by a paired t-test. RESULTS: The amounts ingested and intake volume per minute were lower while sipping/lapping compared to suckling. The overall heart rate and SpO(2) showed no statistically significant difference. The frequency of swallows followed by inspiration (27.6+/-0.8% and 31.0+/-1.3%) and swallows followed by expiration (46.4+/-0.9% and 45.4+/-1.4%, sipping and suckling, respectively) also showed no difference. Tongue movements while sipping/lapping differed from those while suckling a bottle or breast. CONCLUSION: Because physiological parameters and the relationship between swallowing and respiration while sipping/lapping are comparable to those while suckle bottle-feeding without any hydrostatic pressure, sipping/lapping is a safe alternative feeding method to suckle bottle-feeding, even in preterm infants.

The use of dried bakery products in a free-choice feeding method for small-scale broiler production.

Waste material from bakeries is an unconventional energy feed source which is available in sufficient quantities for use in small-scale broiler production in South Africa. Small-scale broiler producers do not have access to the computer programs required to balance home-mixed rations. This investigation confirms that the use of dried bakery products (DBP) in a 2-stage, free-choice method can be used to compensate for this lack. A total of 570 day-old male broiler chickens was assigned to 3 feeding treatments: the control group was fed a 2-stage feeding programme using standard commercial starter and grower rations. The 2nd group received a commercial starter ration up to Day 7 and was thereafter given a choice of a commercial starter ration with normal salt content (0.35%) and DBP. The 3rd group was fed a commercial starter ration up to Day 7, then offered a choice of commercial starter ration with a lower salt content (0.1%) and DBP. The low salt alternative was used to test whether the higher salt percentage in DBP influenced the choice of feed by the birds. It was found that the control group consumed significantly more feed (P < 0.05) and was significantly heavier (P < 0.05) than the experimental groups. However, there was no significant difference between the 2 experimental groups, which indicated that salt content did not play a role in the choice of ration. Feed consumption by both experimental groups was about one-third less than the control group, but the profit margin, as calculated using gross margin analysis, was approximately 15 % higher. It was therefore concluded that dried bakery products can be profitably incorporated as an energy feed source, using the free-choice feeding method, in small-scale broiler enterprises.

A simple, artificial-membrane feeding method for the radio-isotope labelling of Aedes aegypti polypeptides in vivo.

An artificial feeding unit has been designed and constructed to feed laboratory-bred Aedes aegypti with a radio-isotope (35S), so that the mosquitoes' polypeptides can be labelled in vivo. In the unit, a piece of Parafilm M barrier film is stretched over the bottom, outer surface of a polystyrene Petri dish, to create a small gap in which the mixture of blood and radio-isotope is placed. Warm water is placed in the dish, to keep the blood at about 37 degrees C. When such units were placed on net-covered rearing cages, almost all (80%-90%) of the female mosquitoes in the cages took bloodmeals from them. When checked by polyacrylamide-gel electrophoresis and autoradiography 1 h after feeding had begun, the blood-fed mosquitoes were found to have radio-labelled polypeptides. The unit is simple, easy to handle, disposable and can be used to offer small blood samples (>or=50 microl) to Ae. aegypti and, presumably, other mosquito species.
