Zusammenfassung: | Data used in the article One but not two grandmothers increased child
survival in poorer families in west Bohemian population Human childrearing
is characterized by cooperative care and grandmothers are usually the most
prominent alloparents. Nevertheless, it has been argued that limited
resources may intensify competition among kin. The effect of grandmothers’
presence on child survival may thus crucially depend on the family’s
socioeconomic status. We evaluate the impact of grandmothers’ presence on
child survival using a large historical dataset from eighteenth to
nineteenth-century western Bohemia (N = 6880) and assess the effects of
socioeconomic status. We employed a varying effects model conditioned on
relatedness between individuals because of possible genetically
transmitted benefits. Proportional hazards showed that grandmothers had
little or no impact on child survival in families of high and medium
socioeconomic status (farmers and cottagers, respectively), while in
families with the lowest socioeconomic status (lodgers), grandmothers’
presence increased the survival probability of children up to five years
of age. The beneficial effect of grandmaternal care was strongest between
the first and second year of life. Importantly, though, in families with
low socioeconomic status, we also observed lower survival chances of
children when both grandmothers lived in the same village. These findings
suggest that the balance between kin cooperation in childrearing and
competition over resources may depend on resource availability. |
