Independent-group t-tests were conducted to compare mean log CRP levels between groups of girls based on investment in growth and adipose reserves, as defined by median splits for height velocity and global adiposity.

Frequent turnover, requiring some relatively constant commitment of energetic resources, though the metabolic cost of this is unknown. Our data also imply that there are meaningful differences in low levels of CRP.

As an anti-inflammatory effect [51]. How other types of physical activity, such as that associated with agricultural lifestyles, relates to immune function is an important locus for future research. The dominant public health discourse concerning CRP is one of pathology and "chronic inflammation", yet for at least a decade human biologists working in non-Western populations have found lower CRP th
Urrent caloric excess, but still have very low absolute levels of adipose tissue. While organisms may use markers of energetic balance to judge whether to embark upon long term energetic projects, such as female reproduction [6], an acute immune response will demand a large amount of energy in a short period of time [3]. Given this, it may be more reliable for organisms to use signals of energetic
