Objective To assess the possible effects of residential characteristics on the association between oral hygiene and body mass index (BMI) of elderly people in Indonesia. Methods This cross‐sectional study involved 186 participants (87 males, 99 females) aged ≥60 years who were randomly recruited from 8 community health stations for the elderly people. Dentition status, oral hygiene index (OHI), probing pocket depth (PPD) and clinical attachment level (CAL) were assessed in accordance with WHO guidelines. Salivary condition was assessed through the unstimulated whole saliva collection method. Education status and oral health behaviours were evaluated using a standardised questionnaire. BMI was calculated as weight in kilograms divided by height in metres squared. Participants were grouped in accordance with their OHI status (poor, moderate or good) combined with their residential characteristic (rural or urban) to assess the independent effect of OHI and residential characteristic on BMI through linear regression analysis with confounder adjustment. Results In the crude model of linear regression analysis, the poor OHI group is associated with low BMI regardless of their residential characteristic (rural/urban) when compared to the “good OHI, urban” group with P‐values of .045 and
