A study conducted in three Greek villages found that a diet based on traditional Mediterranean eating patterns significantly reduces overall mortality in elderly people. The study used a validated questionnaire to assess dietary habits and found that a one-unit increase in the diet score, based on eight components of the traditional Mediterranean diet, was associated with a 17% reduction in overall mortality. The diet included high consumption of legumes, cereals, fruits, and vegetables, and low consumption of meat and dairy products. The study also found that older age was a significant predictor of mortality, while current smoking and male sex were not. The results suggest that a diet meeting current health criteria can predict survival among elderly people. The study also discussed the cost-effectiveness of antenatal screening for cystic fibrosis. The analysis considered different screening strategies, including sequential and couple screening, and estimated the cost per affected pregnancy detected. The results showed that sequential screening costs between £40,000 and £90,000 per affected pregnancy detected, while couple screening was more expensive, ranging from £46,000 to £104,000. The study concluded that while economic analysis cannot determine screening policy, it provides the NHS with the information needed to inform decisions on the introduction of a screening service for cystic fibrosis.A study conducted in three Greek villages found that a diet based on traditional Mediterranean eating patterns significantly reduces overall mortality in elderly people.
