Résumé
Postprandial thermogenesis was assessed by indirect calorimetry in 32 Gambian women classified into three groups as follows: 12 non-pregnant non-lactating and 10 lactating women studied during the dry season and 10 lactating women studied during the rainy season. The test meal consisted of a typical Gambian breakfast and its energy content corresponded to 30% of the individual's resting metabolic rate (RMR)/24 h. During the dry season, the postprandial thermogenesis of the lactating women averaged 6.0 +/- 0.4% of the test meal energy content and was similar to that observed in the non-pregnant non-lactating women studied during the same season (5.8 +/- 0.3%). In contrast, the postprandial thermogenesis of lactating women studied during the rainy, nutritionally unfavourable season was found to be significantly lower (4.9 +/- 0.5%). There was no significant difference in the pre- and postprandial respiratory quotients among groups. This leads to the conclusion that lactation does not alter the thermogenic response to food and that the reduction in postprandial thermogenesis observed in lactating women during the wet season constitutes an adaptive response to energy deficit allowing a saving of energy in periods of food restriction.
