Background Social isolation and loneliness are serious public health risks affecting a significant number of older adults globally. However, it is uncertain whether their health effects are short-term or long-term, which impedes the developing of more effective and precising interventions. We therefore assessed the varied health effects of short-term and long-term exposure of social isolation and loneliness among a nationwide sample of older adults from China. Methods We assessed social

Social isolation was assessed in terms of absence of key family members, including spouse, children or siblings, and a deficiency in participating in social activities. Loneliness was administered by using a questionnaire. Four health outcomes were investigated: self-rated health, activities of daily living (ADLs), Instrumental activities of daily living (IADLs), and cognitive function measured by Mini-Mental State Examination (MMSE). We used different tests and multivariate regression analyses to examine the short-term (< 3 years) and long-term (>= 3 years) effects of social isolation and loneliness on health outcomes.Results After controlling for covariates of demographic, socioeconomic, lifestyle, and baseline health factors, in the short-term effects, there are significant associations found between absence of children and poor SRH and cognitive impairment (ORs=1.53 and 9.87); absence of siblings and poor SRH, cognitive impairment, and difficulty with ADLs and IADLs (ORs=1.29, 1.35, 1.26 and 1.22 respectively); loneliness and poor SRH and difficulties with IADLs (ORs=1.92 and 1.55). While, in the long-term effects, absence of siblings is marginally significantly associated with cognitive impairment (OR=1.21), but significant associations are found between deficiency in participating in social activities and poor SRH, difficulty with ADLs and IADLs (ORs=1.33, 1.55 and 1.69, respectively); loneliness and poor SRH, difficulty with IADLs and less difficulties in ADLs (ORs=2.96, 2.45 and 0.32, respectively).Conclusions The results of this study show that social isolation at family level mainly have short-term effects, while social isolation at societal level have mainly have long-term, and loneliness has both short-term and long-term effects on older people's health outcomes.
