Gender specific associations and interactions of fat quality with sleep and mental health in the elderly

Fat quality indicators exhibit complex and gender-dependent associations with mental health and sleep outcomes in older adults. While higher FQI appears protective against anxiety, it may elevate depression risk. A favorable omega-3/omega-6 ratio supports sleep and reduces depression risk but may increase anxiety. Elevated CSI correlates with improved sleep yet heightened anxiety and stress. These findings underscore the nuanced role of dietary fat composition in psychological well-being and sleep, highlighting the importance of personalized nutritional strategies.
