Association between and body mass index in healthy subjects; a theoretical pilot study.

Background: is a prevalent protozoan of the gut lumen with worldwide distribution. Recent studies showed that this microorganism may alter both richness and diversity of the gut microbiota. In the current study we assessed the dietary intakes in two -positive and -negative groups to evaluate the impact of this protozoan on the body mass index (BMI) and the dietary intakes.

Methods: In total, ninety-three participants consisted of 17 and 76 -positive and -negative subjects, respectively, were included in this study. Positive cases of had been confirmed by microscopy and culture medium. Moreover, a standard FFQ was filled out for all participants and independent t-test was employed to evaluate the correlation between and the dietary intakes.

Results: From participants, 21/93 (22.58%) and 72/93 (77.42%) were male and female, respectively. The mean age ± SD among -positive and -negative individuals was 39.41 ± 14.60 years and 37.37 ± 13.16 years, respectively. Furthermore, -positive participants had lower weight (67.84 ± 12.29 kg) in comparison to -negative individuals (69.80 ± 14.99 kg). Indeed, BMI of -positive subjects was 25.46 ± 4.66 and lower than -negative subjects 25.89 ± 5.01; ( value = 0.745).

Conclusions: Our findings showed that BMI in -positive subjects was lower than -negative persons. probably affects the dietary intakes and energy metabolism.
