Introduction: Among the world's longest-lived communities the so-called Longevity Blue Zone (LBZ) of Sardinia, Italy, has attracted a lot of interest. In the present study, health profile and functional characteristics of LBZ oldest-old were compared with an age-matched sample from Northern Sardinia (NSS) with a lower longevity level. Methods: Cognitive status, symptomatic depression, disability, and nutritional status were assessed by standardized instruments. In addition, the proportion of escapers (illness-free medical history), delayers (illness only after age 80), and survivors (at least one disease before age 80) was calculated. Results: Three hundred individuals, 150 from the LBZ (age range 89-101, 89 women), and 150 from NSS (age range 89-101, 101 women) were enrolled. The proportion of married individuals in the LBZ cohort was significantly greater compared with the NSS (55% vs. 32%, p = 0.0001). The educational level among nonagenarians in the LBZ was almost half compared with NSS (p < 0.0001). Unskilled workers, shepherds, and peasants prevailed in the LBZ (79% vs. 21%, p < 0.0001). Institutionalized subjects were 1% in the LBZ and 14% in the NSS (p < 0.0001). Disability, comorbidity, and daily physical activity were more represented in LBZ. There was a significantly higher percentage of delayers (37% vs. 18%, p < 0.0002), and a reduction in the number of survivors (30% vs. 44%, p = 0.012) in the LBZ compared with the NSS group. The proportion of escapers was similar in both groups (33% vs. 38%, n.s.). Conclusion: These findings suggest that in the LBZ there are factors enabling frail individuals to live longer despite a greater burden of comorbidity.

Abstract

Introduction: Among the world's longest-lived communities the so-called Longevity Blue Zone (LBZ) of Sardinia, Italy, has attracted a lot of interest. In the present study, health profile and functional characteristics of LBZ oldest-old were compared with an age-matched sample from Northern Sardinia (NSS) with a lower longevity level. Methods: Cognitive status, symptomatic depression, disability, and nutritional status were assessed by standardized instruments. In addition, the proportion of escapers (illness-free medical history), delayers (illness only after age 80), and survivors (at least one disease before age 80) was calculated. Results: Three hundred individuals, 150 from the LBZ (age range 89-101, 89 women), and 150 from NSS (age range 89-101, 101 women) were enrolled. The proportion of married individuals in the LBZ cohort was significantly greater compared with the NSS (55% vs. 32%, p = 0.0001). The educational level among nonagenarians in the LBZ was almost half compared with NSS (p < 0.0001). Unskilled workers, shepherds, and peasants prevailed in the LBZ (79% vs. 21%, p < 0.0001). Institutionalized subjects were 1% in the LBZ and 14% in the NSS (p < 0.0001). Disability, comorbidity, and daily physical activity were more represented in LBZ. There was a significantly higher percentage of delayers (37% vs. 18%, p < 0.0002), and a reduction in the number of survivors (30% vs. 44%, p = 0.012) in the LBZ compared with the NSS group. The proportion of escapers was similar in both groups (33% vs. 38%, n.s.). Conclusion: These findings suggest that in the LBZ there are factors enabling frail individuals to live longer despite a greater burden of comorbidity.
