      abstract     = {To determine the prevalence of overweight and obesity, and
                      to identify factors associated with obesity, among the
                      oldest old.For this study, data from follow-up (FU) wave 7
                      and FU wave 8 of the 'Study on Needs, Health Service Use,
                      Costs and Health-Related Quality of Life in a Large Sample
                      of Oldest-Old Primary Care Patients (85+)' (AgeQualiDe) were
                      used. At FU wave 7, the mean age was 88.9 years (SD: 2.9;
                      85-100 years). Body-mass-index (BMI) categories were defined
                      according to the World Health Organization (WHO) thresholds:
                      underweight (BMI < 18.5 kg/m²), normal weight (18.5 kg/m²
                      ≤ BMI < 25 kg/m²), overweight (25 kg/m² ≤ BMI < 30
                      kg/m²), and obesity (BMI ≥ 30 kg/m²). Longitudinal
                      regression analysis was used to determine factors associated
                      with obesity.At FU wave 7, 3.0 $\%$ were underweight, 48.9
                      $\%$ were normal weight, 37.9 $\%$ were overweight, and 10.2
                      $\%$ were obese. Regressions showed that the probability of
                      obesity decreased with age (OR: 0.77 [95 $\%$ CI:
                      .593-.999]) and less chronic conditions (OR: 1.32 [95 $\%$
                      CI: 1.11-1.57]). The probability of obesity was not
                      associated with sex, educational level, marital status,
                      social isolation, visual impairment, hearing impairment,
                      depression, and dementia.Nearly half of the individuals in
                      very late life had excess weight. Thus, excess weight
                      remains a major challenge, even in very old age. Given the
                      demographic ageing in upcoming decades, this is an issue
                      which we should be aware of.},
