TI  - Diet, energy expenditure, and body composition of lactating Ribeirinha women in 
      the Brazilian Amazon.
PG  - 722-34
AB  - Lactation is the most energetically demanding part of human reproduction; yet, 
      compared with pregnancy, we know little about the strategies women in different 
      settings employ to cope with these increased energy demands. This paper takes a 
      biocultural approach and reports longitudinal data on the anthropometry, dietary 
      intakes and energy expenditure of a sample of 23 rural, lactating Ribeirinha 
      women living in subsistence-based communities in the eastern Amazon. The dietary 
      intakes of these lactating women were insufficient to meet their lactating energy 
      needs and were least sufficient during resguardo, a 40-day period in the 
      immediate postpartum when the women observed a series of food taboos and work 
      restrictions. Instead, the women in this study met the increased energy demands 
      of lactation by drawing on their energy reserves and reducing their energy 
      expenditure in physical activity. The women showed a significant reduction in 
      weight (P<0.001), BMI (P<0.001) and in circumferences (hip, P=0.01; waist, 
      P=0.03) and skinfolds (thigh, P=0.03) in the gluteal femoral region. Total daily 
      energy expenditure (TDEE) was lowest during resguardo and increased as lactation 
      progressed (P=0.01). While the practice of resguardo reduced maternal energy 
      expenditure and allowed women more time to spend with their newborn infants, it 
      came at a cost (low dietary intake), which appears to be related to the loss of 
      the adult woman from subsistence activities. By taking a biocultural approach 
      this study illustrates the role the social environment plays in shaping the 
      experience of lactating women.
