Prevalence of overweight and underweight in schoolchildren in Constantine, Algeria: comparison of four reference cut-off points for body mass index.

Background: Algeria is experiencing a nutritional transition and increasing overweight in children.

Aims: This study aimed to determine the prevalence of overweight and underweight in children aged 6-10 years in Constantine city, Algeria using four international reference cut-offs for body mass index.

Methods: A cross-sectional study was conducted between February and May 2015 with a sample of 509 schoolchildren aged 6-10 years.

Bile acid receptor TGR5 is critically involved in preference for dietary lipids and obesity.

We investigated the implication of Takeda G protein-coupled receptor 5 (TGR5) in fat preference and fat sensing in taste bud cells (TBC) in C57BL/6 wild-type (WT) and TGR5 knock out (TGR5/) male mice maintained for 20 weeks on a high-fat diet (HFD). We also assessed the implication of TGR5 single nucleotide polymorphism (SNP) in young obese humans. The high-fat diet (HFD)-fed TGR5/ mice were more obese, marked with higher liver weight, lipidemia and steatosis than WT obese mice.
