“…The metabolic rate of sleeping infants in thermoneutral conditions was estimated to be 50 W/m 2 . It is the average from earlier studies: 28-55 W/m 2 (Arkell et al 2007), mean (SD) 45(10) W/m 2 (Hull et al 1996a, b) and 53-60 W/m 2 (Rising et al 2003). The diVerence between observed clothing insulation in use and IREQ [observed clothing insulation (clo) ¡ required clothing insulation (clo)] was calculated.…”

Evaluation of the thermal insulation of clothing of infants sleeping outdoors in Northern winter

It is a common practice in Northern countries that children aged about 2 weeks to 2 years take their daytime sleep outdoors in prams in winter. The aim was to evaluate the thermal insulation of clothing of infants sleeping outdoors in winter. Clothing data of infants aged 3.5 months was collected, and sleep duration, skin and microclimate temperatures, humidity inside middle wear, air temperature and velocity of the outdoor environment were recorded during sleep taken outdoors (n = 34) and indoors (n = 33) in families' homes. The insulation of clothing ensembles was measured by using a baby-size thermal manikin, and the values were used for defining clothing insulation of the observed infants. Required clothing insulation for each condition was estimated according to ISO 11079. Clothing insulation did not correlate with ambient air temperature. The observed and required insulation of the study group was equal at about -5 °C, but overdressing existed in warmer and deficiency in thermal insulation in colder temperatures (r (s) 0.739, p< 0.001). However, even at -5 °C a slow cooling (ca. 0.012 °C/min) of mean skin temperature (T (sk)) was observed. When the difference between observed and required insulation increased, the cooling rate of T (sk) increased linearly (r (s) 0.605, p < 0.001) and the infants slept for a shorter period (r (s) 0.524, p = 0.001). The results of this study show the difficulty of adjusting systematically the optimal thermal insulation for outdoor sleeping infants during northern winter. Therefore, the necessity for guidelines is obvious. The study provides information for adequate cold protection of infants sleeping in cold conditions.

“…The recording of energy and macronutrient intake started one-hour prior to and ended one-hour before the conclusion of the 24-hour metabolic testing period. The one-hour off-set was necessary to include or exclude energy consumed before and after the metabolic testing period which compensates for variations in feedings and the intestinal transient time in this age group of infants [15]. …”

“…In a similar manner the total amount of interaction time by biological mothers one hour prior to feeding was calculated by taking the sum of all summary periods one hour prior to each feeding episode. Finally, the total time infants spent engaged in feeding was calculated by taking the sum of all summary periods were the infant was being fed [15]. Feeding included all formula and complementary foods.…”

“…Once all of the instruction and instrument calibrations were completed each infant was placed in the EMTAC for 24-hours from 9:30 AM till 9:29 AM the following day for continuous measurements of energy expenditure (EE; kcal/min) and physical activity (PA; oscillations in weight/min/kg body weight) as described previously [15]. Any supplies such as diapers, formula, complementary infant foods or toys were placed in the EMTAC in hanging bags before the start of the test.…”

“…Obese biological mothers may interact in such a way as to possibly contribute to greater energy intake in their infants earlier in life. Recently we published the results of 24-hour metabolic measurements in four-to-six month old infants in the Enhanced Metabolic Testing Activity Chamber (EMTAC) [15]. This study allowed collection of data to assess the relationship between maternal body composition and infant feeding and interaction patterns.…”

Background: There are no data regarding the relationship between maternal adiposity and interaction and feeding of infants and possible contribution to childhood obesity. In this study we determined the relationship between maternal body weight and composition and infant feeding patterns and maternal-infant interaction during 24-hour metabolic rate measurements in the Enhanced Metabolic Testing Activity Chamber (EMTAC).
