A trio of sisters from Brazil has drawn global attention after Guinness World Records recognized them as the world's oldest living sibling group, with a combined age of 316 years. Researchers at the University of Sao Paulo have launched the DNA Longevo Project to investigate the biological factors that keep them physically and mentally robust well beyond a century. By analyzing families with multiple centenarians, scientists hope to identify genetic markers that protect against frailty, cognitive decline, and age-related illness.
Meet the Sisters: Ages 103, 104, and 109
The sisters live in Rio de Janeiro and were identified through LongeviQuest, an organization that verifies longevity records and partners with Guinness World Records. Zulina de Deus Nunes is 103, Zoraide de Deus Mota is 104, and Levita de Deus Nunes is 109. Levita worked as a craftswoman and later at a television network. Zoraide was a nurse and raised five children. Zulina was a stay-at-home mother who raised six children. All three describe their lives as fairly ordinary, each crediting a healthy diet and an active lifestyle for their long years. One recalled a childhood spent swimming and fishing in rivers when food was fresh and refrigeration was not available. Another stressed the importance of breastfeeding in early life.
DNA Longevo Project: Uncovering Genetic Secrets
The DNA Longevo Project is led by Mayana Zatz from the Human Genome Research Centre. The study aims to understand why some individuals remain physically and cognitively robust at very advanced ages. Researchers will compare nonagenarians and centenarians with people who have developed frailty, cognitive decline, or chronic disease. The goal is to identify inherited traits linked to longevity. The team plans to use DNA testing to look for protective genes. According to Zatz, the more families with multiple centenarians included, the more accurate the findings will be. A representative from LongeviQuest noted that when siblings reach such ages, a strong genetic element is likely, though living near one another and having family support also matter. The academic team believes inherited factors could carry more weight than environmental influences in maintaining health later in life.
Study Targets 500 Centenarians for Definitive Conclusions
The study has set a target of 500 centenarians to reach more definitive conclusions about longevity. Investigators hope to learn how genetic factors might protect the heart, muscles, and cognitive function from age-related decline. The report was filed by correspondents in Rio de Janeiro and Sao Paulo and edited by senior editorial staff.
Social Media Reactions
Several social media users, including Nigerians around the world, reacted to the video of the three sisters. Danis commented, 'My grandmother is 113 years old.' ÀBÜ SǟЎэɇ wrote, 'My grandfather is 109 years old and still alive.' Amanda is Singing said, 'I also want to know if they’re living together. Genetics is a factor—but so is quality of life. If they get to spend a lot of time together and with family and friends, it’s really good for their health.'
