The Cloisterstudy - Or is there a biological age gap between men and women?

A data-heavy posting, more formating and translation work than anything else:

The starting point and until today the most important research project of the cloister study is the question if male excess mortality (in the industrialized countries currently 5-8 years in life expectancy at birth) is mainly caused by biological factors (genetic or hormonal differences) or non-biological factors (differences in life-style or environmental issues). The fact that non-biological risk factors can be largely ruled out inside the catholic cloistered population allows testing the impact of biological causes on female survival advantages. The works of this study have been awarded with the first prize for researches by young scholars of the German Foundation for World Population (DSW) and the German Association for Demography (DGD) in 1998 and with the Gunther Beyer Award of the European Association of Population Studies (EAPS) in 2003.

Life expectancy at age 25 for German females and males and for Bav. nuns and monks represented at the mid calendar year of the observation periods



Frauen = Women | Männer = Men | Nonnen = Nuns | Mönche = Monks

In conclusion, if there is a biological difference, the difference is very small (about 2 years). To answer the question why men die earlier, we have to look at many different factors and I will eventually do so in another post. Nevertheless male health does not have the same focus female health has and without a doubt the difference in mortality rates is another reason we should have a closer look at men's health.

  2. Hallo,

    gibt es den Text auch in deutsch?

    Ich würde das gerne in WikiMANNia einbauen, natürlich mit Quellenangabe hierher.

  4. Outstanding post Feck! Looking forward to more on this. If I could actually make the argument that the life expectancy gender gap is not innate... well, it would do my work on men's issues a world of good.
