Urban Farm DB summary
A survey in October 2024 of 363 Tongan adults involved in homestead gardening across four islands investigated dietary diversity. While 79% of participants achieved a dietary diversity score of 5 or higher, a negative significant association was found between dietary diversity and both garden participation length and knowledge of nutrient composition for iron and vitamin C. No statistical significance was found between dietary diversity and garden location by island, but an effect by district location was observed.
