Abstract

Introduction Despite many health benefits from dietary fiber, inadequate intake is prevalent among elderly population. This study aims to obtain the pattern of fiber intake in different socio-demographic backgrounds among elderly in Jakarta area, Indonesia and its’ associated factors. 
 Methods: A cross-sectional study was conducted among elderly aged > 60 years in 5 community health center across Jakarta province. A total of 126 elderly were interviewed using two non-consecutive 24-h dietary recall methods to obtain dietary intake data. Socio-demographic backgrounds on age, sex, education, income, marital status, and energy intake were assessed using structured questionnaire. Mann-Whitney or independent t-test was performed to measure the different of fiber intake in each socio-demographic variable. Linear regression test was performed to analyze the variables that associated with fiber intake.
 Results: Majority of 98.4% of elderly have total fiber intake <80% of Indonesian Recommended Dietary Allowance (RDA) with average intake of 6.6 g/d. Lower fiber intake was significantly found in females, widowed/separated, have lower education and income, and have inadequate energy intake. Factors associated with total fiber intake were income (adjusted β=0.20, p=0.01) and energy intake adequacy (adjusted β=0.65 p=0.00).
 Conclusion: Fiber intake among elderly in urban area is inadequate and the pattern was worse in the low socio-demographic settings. By this finding, it is important to give priority to the socially disadvantages group when formulating nutrition intervention policy in this population setting.
