Total daily energy expenditure (TDEE) and energy expended in activity (EAC) were estimated by the minute-by-minute heart-rate method in 22 (16 men, 6 women) individually calibrated subjects and compared with values obtained by whole-body indirect calorimetry. Subjects followed four activity protocols during the 22 h in the calorimeter; no exercise (n = 6)(More)
BACKGROUND Knowledge on human papillomavirus (HPV) genotype distribution in recurrent respiratory papillomatosis (RRP) is essential to assess the impact of HPV vaccine. It is provided information for Colombia. METHODS In all, 189 RRP primary cases diagnosed between 1985 and 2009 were identified from 5 pathology laboratories of Cali and Medellin, Colombia.(More)
Using minute-by-minute heart rate recording, the pattern of energy expenditure (EE), total daily energy expenditure (TDEE) and energy expenditure in activity (EAC) were measured in 132 boys and 110 girls 6-8, 10-12 and 14-16 years of age during ordinary school days. The children were living under economically deprived conditions in Colombia; 70 boys and 59(More)
Treadmill measurements of maximum oxygen intake were made in 218 boys and 136 girls 6-16 years of age who were classified as nutritionally normal or marginally malnourished. max (1· min-1 )increased with age, was lower in the undernourished than in the normal, and was significantly lower in girls than in boys. The sex differences persisted when max was(More)
BACKGROUND This study examined the components of energy balance in poor, free-living pregnant women living in an urban setting of a developing country. OBJECTIVES We tested the following hypotheses: 1) energy intake increases in pregnancy and is greater than when nonpregnant and nonlactating (NPNL), 2) basal metabolic rate (BMR) increases in pregnancy and(More)
Measurements of basal metabolic rate (BMR) were made in 528 children 2-16 y of age living in underprivileged areas of the city of Cali, Colombia (153 control and 186 undernourished boys, 93 control and 96 undernourished girls). The data are related to BMR calculated from the equations of Schofield and to estimates of the lean body mass (LBM). The ethnic(More)
Anthropometry, basal metabolic rate (BMR), and resting energy expenditure (RMR) measured by indirect calorimetry and total daily energy expenditure (TDEE) by the minute-by-minute heart rate (HR) method have been studied in 52 school-aged girls 6-16 years and 46 nonpregnant, nonlactating women 19-43 years of age. BMR, RMR, and TDEE increased with age in(More)
