Among the economically deprived community-dwelling Chinese older adults, we examined the associations between levels of food insecurity and (1) various types and (2) the number of geriatric syndromes, and investigated the mediating role of malnutrition risk in these relationships.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cross-sectional study was conducted. 281 older adults aged\u2009\u2265\u200965 years with household income\u2009&lt;\u200975% of the population median and participating in a food assistance program evaluation study in Hong Kong were included.

The mean (SD) food insecurity score was 0.79 (1.56). The majority (88.0%) had at least one geriatric syndrome. Logistic regressions showed that every one-point increase in the food insecurity score was significantly associated with a higher malnutrition risk [adjusted Odds Ratio (aOR):\u00a01.94, 95% CI 1.48\u20132.55], possible sarcopenia (aOR:\u00a01.41, 95% CI 1.15\u20131.74), falls (aOR:\u00a01.33, 95% CI 1.11\u20131.61), and frailty (aOR:\u00a01.26, 95% CI 1.02\u20131.56), and a 43% greater risk of having one additional geriatric syndrome (aOR:\u00a01.43, 95% CI 1.23\u20131.66). The proportions of association mediated by malnutrition risk were 48.6% for possible sarcopenia, 50.0% for falls, 91.3% for frailty, and 90.5% for the number of geriatric syndromes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Food insecurity was associated with geriatric syndromes, and malnutrition risk mediated these relationships.
