Hypothesis

The study aims to evaluate the role of MMP-2 promoter polymorphisms in percentage body fat as a measure of childhood obesity.

Conclusion

The study suggests a possible genetic contribution to childhood obesity through MMP-2 promoter haplotypes.

Supporting Evidence

  • The study identified a genetic association between MMP-2 promoter haplotypes and percentage body fat in children.
  • Environmental factors were previously shown to influence body fat in the same study group.

Takeaway

The study found that certain gene variations might affect how much body fat children have, which is important for understanding obesity.

Methodology

Participants were genotyped for three MMP-2 promoter SNPs and analyzed for their association with percentage body fat using bioelectrical impedance analysis.

Potential Biases

Potential bias due to the disproportionate sample of small for gestational age and appropriate for gestational age infants.

Limitations

The study's findings may not be generalizable due to poor follow-up of non-European ethnicities.

Participant Demographics

Children from the Auckland Birthweight Collaborative study, primarily of European ethnicity.
