Abstract

A cross-sectional observational study was conducted to describe the lifestyle of people ≥90 years, living in Evdilos or Raches, two municipalities of the Greek island of Ikaria, classified a longevity blue zone. The 71 participants were interviewed and underwent the Mediterranean Islands study food frequency questionnaire (MEDIS-FFQ) and the international physical activity questionnaire (IPAQ). The frequency of social contacts was daily for 77.9% of participants, weekly for 16.1%, and monthly for 5.9%. Most participants (90.0%) believed in God, and 81.4% took part in religious events. A total of 62.0% attended Panigiria festivals. Access to primary health care was considered difficult in the past for 66.2% of participants, while 22.1% felt that it remained difficult at the time of the survey. The level of adherence to the Mediterranean diet was 62.7% (61.6% in women and 64.0% in men). Physical activity levels were moderate or high for 71.8% of participants (59.5% of women and 85.3% of men). In conclusion, the participants had a very high level of family solidarity, social interaction and physical activity. The results concerning the Mediterranean diet are less convincing. It would be interesting to study the impact of these factors on the longevity of the oldest old aged people living in Ikaria.

  • Blue Zones share common dietary, lifestyle, and social factors that contribute to the remarkable health and longevity of their residents.

    “Despite their diverse cultural and environmental contexts, Blue Zones share common dietary, lifestyle, and social factors that contribute to the remarkable health and longevity of their residents [7,148,149,150,151,152].”

    From The Power of Environment: A Comprehensive Review of the Exposome's Role in Healthy Aging, Longevity, and Preventive Medicine-Lessons from Blue Zones and Cilento (2025) · cites this paper as [151]

    The Introduction and Conclusions describe diet, physical activity, and social life among people aged 90 or older in Ikaria. They do not establish that these factors are shared across Blue Zones; the Conclusions also call for a study to assess their impact on longevity, rather than finding that they contribute to it.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
