Me. Valencia et al., ENERGETIC CONSEQUENCES OF MILD GIARDIA-INTESTINALIS INFESTATION IN MEXICAN CHILDREN, The American journal of clinical nutrition, 61(4), 1995, pp. 860-865
This study explored the effects of mild infestation with Giardia on en
ergy intake and expenditure at rest and in activity in an urban Mexica
n population. Ten boys aged 6-10 y living in low-income sectors in nor
thwest Mexico who had Giardia infestation were recruited. Energy intak
e, basal metabolic rate (BMR), and total free-living expenditure (TEE)
measured by the doubly labeled water method were determined for 7 d d
uring both infestation and after treatment. There was no significant d
ifference in recorded energy intake between the two periods (7.76 and
7.70 MJ/d; P = 0.847). BMR showed no significant change in response to
treatment; values were 4.79 and 4.86 MJ/d (P = 0.03). The mean TEE in
creased by almost 1 MJ/d in the Giardia-free period. This increase was
observed in 8 of the 10 subjects; however, the overall change was not
statistically significant (P = 0.08).
