Sociodemographic Factors and Nutritional Knowledge Impacts on Overall Vitamin B12 Intake in Older Women

Abstract

BACKGROUND: The older population is at high risk for vitamin B12 deficiency, leading to various significant and chronic health problems. AIM: This study aimed to determine the association between sociodemographic characteristics, nutritional knowledge and overall vitamin B12 intake among older persons. METHODS: An observational study with a cross-sectional design was directed to 69 older women aged > 50 years. Data was collected from subject responses to various questions on the google platform, guided by professional assistance. RESULT: The study showed an inversed association between employment status (p<0.05), income level (p<0.001) and overall vitamin B12 intake, including dietary and supplement intake. The results provided new insights on monthly income level playing a crucial role in VB12 rich food consumption patterns in older persons, which were mostly unemployed. CONCLUSION: Efforts are needed to increase the coverage of VB12 supplementation, either peroral or intramuscular injection, as a solution to meet the needs of VB12 source that is affordable and effective for the older population.
