California Environmental Protection Agency. In order to evaluate more precisely the potential health risks from air pollution, it is critically important to have accurate estimates of the volume of air breathed (VE) by exposed populations. There is a substantial amount of characteristic VE data available in the literature, but values typically are representative of adult males during rest and in light to moderate activities. This is due in part to difficulties in the direct measurement of VE in free-ranging people, which requires portable respirometers that can restrict normal performance of some common activities. Thus, VE for free-ranging activity has usually been estimated from unobtrusive heart rate (HR) measurements in individuals whose VE to HR relationship response to varied intensities of cycle ergometer or treadmill exercise had been established in the laboratory. However, it is not known how accurately VE is predicted in the field when using this method. To resolve this problem, both VE and HR must be measured simultaneously in the field across a wide range of free-ranging activities. The primary purposes of this research were to 1) identify mean values and ranges of VE for specific activities and populations, and 2) develop equations which would permit VE predictions based on known activity and population characteristics. The subject population utilized in this study comprised 160 normally active individuals of both genders, and of varied age (6-77 years) and ethnicity. In addition, 40 children (6-12 years) were recruited for data validation and 12 young children (3-5 years) were identified as subjects for pilot testing purposes. Subjects completed resting (lying, sitting and standing) and active (walking and running) laboratory protocols, and usually one or more field protocols (i.e., play, car driving/riding, car maintenance, yardwork, housework, mowing and/or woodworking). Collected laboratory data included steady-state measurements of VE, HR, breathing frequency (fB) and oxygen consumption (VO2), while data collection in the field was limited to the continuous measurement of VE, HR and fB during each protocol. Resting responses for the children's groups revealed no significant gender differences and those for the adult groups demonstrated minimal age-group differences; therefore, resting data were combined into children, adult female and adult male groups. Heart rate and VE responses were poorly correlated in all resting postures for each group. However, fB was a better predictor for VE, with body surface area (BSA) being an important additive variable in multiple regression equations. Very similar observations were obtained from the cross-validation children's group. Regression analysis revealed higher r values for walking and running protocols than for field protocols, which were higher than for resting protocols. Typically, HR was poorly correlated with VE except during active laboratory protocols, whereas fB and BSA were variables that better predicted VE across all types of activities and population groups. The inclusion of all three variables (BSA, HR and fB) in multiple regression equations, generally provided the most accurate predictions of Vs across groups and activity types. The lower precision of prediction for active field protocols than for laboratory walking and running protocols was at~ibuxed primarily to the wide variety of individual activities and intensity of effort during field protocols. Using the mean VE values obtained for each population group and activity, field protocols were categorized into one of the following: sedentary activity, and light or moderate exercise. For the children's groups, spontaneous play protocols were identified as moderate exercise. Car driving/riding was classified as sedentary activity for both genders. Car maintenance for the male adult group was categorized as light exercise, while their VE responses to woodworking, mowing and yardwork protocols were class

    The "refereed" or "peer review" status of a journal comes from the Ulrichsweb Global Serials Directory (http://ulrichsweb.serialssolutions.com/), as supplied by the publisher. The term refers to the system of critical evaluation of manuscripts/articles by professional colleagues or peers. The content of refereed publications is sanctioned, vetted, or otherwise approved by a peer-review or editorial board. The peer-review and evaluation system is utilized to protect, maintain, and raise the quality of scholarly material published in serials. Publications subject to the referee process are assumed, then, to contain higher quality content than those that are not.

The importance of exclusive breast-feeding in the first 6 mo of life is widely recognized, but most mothers still do not reach this goal. Several studies have shown that face-to-face lactation counseling is effective in increasing not only exclusive breast-feeding rates but also the total duration of breast-feeding. However, it is unclear whether counseling could increase breast milk intake. The purpose of this study was to evaluate the effect of lactation counseling on breast milk intake, assessed through the deuterium dilution method. This was a blind, randomized intervention trial of lactation counseling in a sample of 188 babies born in Pelotas, selected with the same criteria used for the WHO Multicentre Growth Reference Study (MGRS). The main outcomes were breast-feeding pattern and duration for all infants as well as breast milk intake for a subsample of 68 infants at the age of 4 mo. Mothers in the control group were almost twice as likely to stop breast-feeding by 4 mo as those in the intervention group (prevalence ratio 1.85; P = 0.04). Cox regression confirmed that the velocity of weaning was twice as high in the control group. Breast milk and total water intakes did not differ between the groups. The deuterium dilution technique proved to be a practical means of assessing breast milk intake. Lactation counseling reduced early weaning, but breast milk intake at 4 mo was not affected.
