In summary, multiple body size indices were associated with high-grade prostate cancer.
Since there are multiple body size traits linked to the broader 2.41 Mb region in many mammalian species, it is likely that there is a common underlying biological mechanism, i.e. loss or gain of function of a single gene through species-specific mutations.
The region that harbors the NCPAG and LCORL genes on OAR6 is highly conserved among mammalian species and multiple body size traits in various species have been associated with this syntenic region, which may reflect that the underlying biological mechanisms share a common ancestry.
Future studies that use a comparative phylogeographic approach, examining multiple species with different body sizes, ecological niches and life histories would be the best approach to understand shared aspects of evolutionary history and ecological response between species.
As we have used multiple measures of body size at four different time points, we have ended up making multiple tests.
Genetic covariance between size and growth at different ages is likely due to pleiotropy, in which expression of single genes (e.g. those that code for growth factors) affect multiple traits (e.g. body sizes) at different ages (Cheverud et al. 1983).
Strengths include the large sample size, multiple measures of body size, and the laboratory techniques for arsenic speciation, characterized by low limits of detection.
The Strong Heart Study (SHS) is a large rural cohort study with standardized measures of cardiovascular risk factors including multiple measures of body size and body composition (body mass index, percent body fat and fat free mass measured by bioelectrical impedance, and waist circumference).
As an integral component of multi-country collaborative research, the Understanding the Relationship between Activity and Neighbourhoods (URBAN) Study seeks to overcome these limitations by determining the strengths of association between detailed measures of the neighborhood built environment with PA levels across multiple domains and body size measures in adults and children.
Boys' and girls' body sizes grow at different rates; however, multiple studies, including ours, have demonstrated that renal length is not significantly different between the sexes.
