Sardinian village where more women reach 100 may be new centenarian ‘blue zone’
A recent study identifies the Sardinian village of Bolotana as a potential new blue zone due to its exceptionally high rate of female centenarians. The research indicates that 13.8% of women in the village who reach age 70 live to 100, a rate that ranks second globally after Hong Kong. This finding marks the first expansion of Sardinia's longevity reputation outside its original designated blue zone in over 25 years.
- ▪Researchers from the University of Sassari and the University of Alabama at Birmingham published findings in Frontiers in Aging regarding the longevity of Bolotana residents.
- ▪Thirteen point eight percent of women in Bolotana who reach age 70 are projected to live to 100, which is significantly higher than the 3.5% national average in Italy.
- ▪The village currently has 12 centenarians among a population of 2,266, a density roughly 12 times the Sardinian average.
- ▪Lead scientist Giovanni Mario Pes noted that female longevity in Bolotana is three times higher than that of most Western women.
- ▪The study analyzed records of individuals born between 1900 and 1925, finding that 38 residents lived beyond the age of 100.
