    (Demographic Research, 2015-01-01) Lipsi, RM; Caselli, G; Pozzi, L; Baggio, G; Carru, C; Franceschi, C; Vaupel, JW; Deiana, L
    © 2015 Rosa Maria Lipsi et al.Objective: This article provides an overview of the AKeA2 study, with a particular focus on data collection concerning family genealogies of the Sardinian centenarians and controls, and on the quality of these data. A first analysis of the main characteristics of the survey data is also summarized and selected preliminary results are presented. Methods: We use descriptive statistics to analyze data collected by the AKeA2 survey on Sardinian centenarians and controls. Results: Centenarian women have on average fewer children, and at an older age, particularly for their last child. The mothers of centenarians, especially centenarian women, lived longer on average than those of deceased controls and controls born between 1905 and 1910 but still living at the moment of the survey.

    Maternal longevity is associated with lower infant mortality
    (Demographic Research, 2014-01-01) Caselli, G; Lapucci, E; Lipsi, RM; Pozzi, L; Baggio, G; Carru, C; Deiana, L; Franceschi, C; Vaupel, JW
    © 2014 Caselli et al.Objective: Referring to the multidisciplinary and multipurpose survey AKeA2, and focusing on family genealogy data on centenarian women and controls, this paper aims to verify the hypothesis that maternal longevity is associated with lower infant mortality in offspring, after having controlled for fertility characteristics, familial longevity and some contextual variables. Methods: The association between the longevity of a mother and her children's infant mortality level was assessed using a multivariate Poisson Regression Model with robust estimates, which is suitable for estimating consistently and efficiently the relative risk when binary data are used. Results: Our results show an association between longevity and infant mortality among the children of the Sardinians who survived to become centenarians. Infant mortality is significantly lower for children belonging to a mother born and living in Sassari and Oristano than Nuoro, close to each other and both located on the Western coast.
