Data of smoking habits and physical activities were obtained by interview and fat intake was determinated by food recall. Data of cognitive ability was obtained through interview using Mini Mental State Exam (MMSE) questionnaire. Data were tested using Spearman correlation to determine the relationship between variables.Results: The results showed that there was a significant relationship between smoking habit with cognitive ability in elderly (P<0.001). There was a significant relationship between physical activity and cognitive ability in elderly (P=0.001). There was no significant relationship between fat intake and cognitive ability in elderly (P=0.494).Conclusion: Low smoking habits and high physical activity was correlated to a better cognitive function in Indonesian elderly.
