Introduction : In line with the rapid growth of elderly population, the quality of life of the elderly needs to be considered. There are several factors that affect the quality of life of the elderly such as balance, depression, and olfactory function. Aim: This study aimed to analyze the association between depression and olfactory function with quality of life among elderly. Methods: This was a cross-sectional study of 100 subjects aged ≥ 60 years in Pusaka Kebon Jeruk, West Jakarta. The variables were assessed by using the World Health Organization Quality of Life–BREF (WHOQOL–BREF) questionnaire, Geriatric Depression Scale-15 (GDS-15), Berg Balance Scale (BBS), and Olfactory Test. Binary logistic regression with backward conditional analysis were used to analyze the association between quality of life and determinant factors. Results: Based on sociodemographic characteristics, the respondents were mostly aged 60-74 years (75 %), had more than 9 years of education (97 %), and mostly woman (71 %). The analysis showed that depression was significantly associated with the social relationship domain (OR= 3,237 ; 95% CI 1,035-10,119 ; p= 0,043) and the overall quality of life (OR= 6,231 ; 95% CI 1,134-34,246 ; p= 0,050). Likewise, olfactory function was also significantly associated with the social relationship domain (OR = 3,327; 95% CI 1,249-8,865 ; p= 0,016). While gender was found to be a protective factor for environment domain (OR= 0,143 ; 95% CI 0,033-0,619 : p= 0,009 Discussion: In this study, depression was significantly associated with social relationship domain and overall quality of life. Olfactory function was also significantly associated with social relationship domain. While gender was found to be a protective factor for environment domain Keywords: Quality of life, depression, olfactory function, balance disorder, elderly.
