>Background. Attention given to frailty or pre-frailty in community-dwelling older adults is limited. Pre-frail is the condition in which individuals either have low handgrip strength (HGS) or low physical activity. This study aims to investigate the prevalence of pre-frailty in a community-dwelling aged population in Hong Kong and identify factors associated with pre-frailty. >Methods. This was the analysis of the baseline data of an interventional study in physical activity. Low handgrip strength was defined as ≤14.35kg for female or ≤22.00 kg for male. Energy consumption per week was measured by accelerometers. Energy consumed less than 270 Kcal/week for female or 383 Kcal/week for male was considered as pre-frail. Correlations and logistic regression models were used. >Results. A total of 199 subjects were included. Mean (SD) of age was 73.4 (7.5). The prevalence of pre-frailty of this sample was 27.1%. Gender (OR=1.1, p<.001), high blood pressure (OR=1.747, p<.01), and number of chronic illnesses (OR = 1.458, p <.05) were associated with pre-frailty. >Discussion. One-third of community-dwellers suffered from pre-frailty but they have never been informed. Pre-frail condition has seldom been given attention in Chinese society, assuming that physical weakness is the norm to aged population. Assessment of frailty should be carried out in the community and strategies to prevent frailty are worthy to be developed.
