The objective of the study was to identify the association between social support and psychosocial well-being among men and women aged over 65 years in Europe during the COVID-19 pandemic.MethodsCross-sectional data on 36 621 men (n=15 719) and women (n=20,902) aged 65 years or higher were obtained from the ninth round of the Survey of Health, Ageing and Retirement in Europe. The outcomes were measured by psychosocial well-being reflected with self-reported depression, nervousness, loneliness and sleep disturbances. Social support was measured in terms of receiving help from own children, relatives and neighbours/friends/colleagues since the pandemic outbreak.ResultAbout one-third of the participants reported depression (31.03%), nervousness (32.85%), loneliness (32.23%) and sleep trouble (33.01%). The results of multivariable regression analysis revealed that social support was a protective factor to psychological well-being. For instance, receiving help from own children (RD=−0.13, 95% CI=−0.14 to –0.12), relatives (RD=−0.08, 95% CI=−0.11 to –0.06), neighbours/friends/colleagues (RD=−0.11, 95% CI=−0.13 to –0.09) and receiving home care (RD=−0.20, 95% CI=−0.22 to –0.18) showed significantly lower risk difference for depression. Similar findings were noted for loneliness, nervousness, and sleep trouble as well, with the risk difference being slightly different for men and women in the gender-stratified analysis. For instance, the risk difference in depression for receiving help from own children was −0.10 (95% CI=−0.12 to –0.08) among men compared with −0.12 (95% CI=−0.14 to –0.11) among women. The risk differences in the outcome measures were calculated using generalised linear model for binomial family.ConclusionFindings of the present study highlight a protective role of social support on psychological well-being among both men and women. Developing strategies to promote social support, especially among older adults, may mitigate the rising burden of psychological illness during the COVID-19 pandemic.
