In December 2017 researchers from Iran published their review of the medical scientific literature to assess the association of fish consumption and dietary intake of omega-3 polyunsaturated fatty acids with the risk of hip fracture. A total of 9 studies involving 292,657 individuals, aged 20 years or older, were included in the review. Results showed that an increased consumption of fish was associated with a reduced risk of hip fracture. A higher dietary intake of omega-3 polyunsaturated fatty acids was also seen to be associated with a reduced risk of hip fracture.
