Time course of events in the SATS according to sociodemographic characteristics. Mean age at AD onset, illness duration, time from diagnosis (start of cholinesterase inhibitor treatment) to NHP, and survival time in NHs. a. In total and according to sex. Females with AD spent on average 1.75 more years (21 months) in NHs than did males (P < 0.001). No sex-based difference was observed regarding age at AD onset, illness duration, age at diagnosis, time between diagnosis and NHP, age at NHP, and age at death. b. The interaction effect of sex with living status. Females living with family showed a trend toward a younger age at the onset of AD symptoms than did the other groups (P = 0.074). Solitary living males with AD exhibited a trend toward a significantly longer illness duration compared with females living alone (P = 0.055). Males living with a family member had longer time from AD diagnosis to NHP than did solitary living females (P = 0.022). Moreover, males living with family spent a mean of ~2–2.5 years less time in NHs compared with the other groups (P < 0.001). No significant differences were detected regarding age at diagnosis, age at NHP, and age at death.
