Objective To explore the impact of intergenerational support and sociodemographic characteristics on attitudes toward aging in urban communitydwelling elderly population. Methods A total of 810 communitydwelling elderly people in Xi′an were investigated by using the Aging Attitude Questionnaire(AAQ) and Intergenerational Support Scale. Results Dimension scores of psychosocial loss, coping with body changes with aging, and psychological acquisition in the AAQ were 21.39±5.55, 26.07±5.04, and 28.32±4.46, respectively, showing significant differences in the elderly with different marriage status, selfrated health and activities of daily living (ADL) level (P<0.01 for all). Age, residence, education, ADL level, chronic disease and caring for offspring were influencing factors of psychosocial loss (P<0.05, P<0.01). Marriage, offspring′s health status, selfrated health, chronic disease, intergenerational emotional support, grandchild care, and receiving support from offspring were predictive factors of psychological acquisition (P<0.05, P<0.01). Age, marriage, selfrated health, chronic disease, intergenerational emotional support, caring for offspring and grandchild were factors affecting coping with body changes with aging (P<0.05, P<0.01). Conclusion The urban communitydwelling elderly have positive attitudes toward aging, and intergenerational support and sociodemographic characteristics show different influences on dimensions of aging attitude. It is necessary to establish a harmonious and healthy intergenerational relationship, and provide individualized psychological counseling, thus to help the elderly to develop more positive attitudes toward aging.
