In the birth statistics since 1990, we find a four-point increase in the sex ratio at birth for mothers born in India, attributable particularly to an increase at higher birth orders, mirroring findings reported for India. This suggests that sex-selective abortion is occurring among mothers born...
Using annual province-level data for the period 1988-2004, we show that a 0.01 increase in the sex ratio raised violent and property crime rates by some 3%, suggesting that the rise in excess males may account for up to one-seventh of the overall rise in crime. 展开 关键词:...

Here, in a coastal seabird, the European shag (Phalacrocorax aristotelis), we studied the influence of climate (North Atlantic Oscillation, NAO; Sea Surface Temperature, SST) on two sex-related population parameters: fledgling sex ratio and sex-specific dispersal. We found that fledgling sex ...
There was an approximate log‐linear relationship between measures of general and central adiposity and the risk ofMIin both sexes. A 1‐SDhigher in body mass index, waist circumference, waist‐to‐hip ratio, and waist‐to‐height ratio, respectively, were associated with hazard ratios (...
