Date Time Empowering older people could be key to positive change A research team led by Curtin University has demonstrated the potential of older people to play a direct role in tackling community issues affecting them such as food security. Published in Health Promotion International, the research put study participants aged 51-87 in the role of citizen scientists as they attended subsidised community market days aimed at improving food security and reported on ways they thought the initiative could be changed to serve them better. Lead researcher, Associate Professor Anthony Tuckett from the Curtin School of Nursing, said being able to afford and access food was an increasing problem for older people who were living longer and having to stretch their financial resources further.
