Reduced circulating folate among older adults caused by continuous work: nested cross-sectional study conducted in a country with folic acid fortification program.

Population aging is 1 of the biggest challenges facing public health today, and cognitive dysfunction is an important concern. Cognitive impairment may be associated with high folate concentrations and low vitamin B concentrations; the latter is a common problem among elderly people. Therefore, we hypothesized there was a high circulating folate concentration among older people living in a country with a mandatory folic acid fortification program.

Educational interventions on nutrition among older adults: A systematic review and meta-analysis of randomized clinical trials.

Poor nutrition is a major risk factor for non-communicable diseases and nutritional deficiencies. Dietary interventions have been proposed to improve eating habits. The aim of this systematic review is to evaluate the efficacy of randomized clinical trials of nutritional interventions in food habits among older people.
