      abstract     = {This study examined the relationship between healthcare
                      utilization and support related factors, such as social
                      support and marital status, in patients with dementia (PwD)
                      over 5 years.We analysed data from 498 participants in the
                      GP-based randomized controlled intervention trial DelpHi-MV
                      (dementia: life- and person-centred help in
                      Mecklenburg-Western Pomerania, Germany). Negative binomial
                      regression was used to model GP and internist visits, while
                      zero-inflated negative binomial regression analysed dentist
                      and neurologist/psychiatrist visits, with predictors
                      including social support and sociodemographic
                      variables.Participants had a mean age of 80.1 years (SD =
                      5.45), with $59.6\%$ female and $43.7\%$ married. Emotional
                      support (β = 0.23, SE = 0.04, p < 0.0001), social
                      integration (β = -0.10, SE = 0.03, p = 0.003), and marital
                      status (divorcés: β = 0.24, SE = 0.07, p < 0.0001;
                      widowers: β = 0.08, SE = 0.04, p = 0.03) were associated
                      with GP visits. Practical support was positively associated
                      with dentist visits (b = 0.27, SE = 0.06, p < 0.0001).
                      Social integration (b = 0.21, SE = 0.08, p = 0.03) and
                      marital status (singles: b = 1.42, SE = 0.24, p < 0.0001)
                      emerged as significant predictors for
                      neurologist/psychiatrist visits.Our findings highlight the
                      importance of social support, including emotional and
                      practical support, social integration, and marital status,
                      as key predictors of healthcare utilization in PwD. These
                      results underscore the need for tailored interventions to
                      address social and demographic disparities in dementia
