Factors Affecting Sex Ratio at birth in Croatia 1998-2008

This study analysed the impact of ecological and population factor on sex ratio at birth in Croatia. The significant factors lowering the sex ratio at birth are the joint higher age of both mother and father and the birth occurring in the Central Croatia. The age-related changes in reproductive physiology alter the sex ratio at birth, and the regional pattern can be attributed to different occurrence of obesity and physical inactivity between the Croatian regions.
