Social support, subjective well-being (SWB), and loneliness are issues of central importance in research concerned with the quality of life (QOL) of elderly people in the 21st century. However, very little is known about the situation in low-income countries such as in Nepal. The purpose of this paper is to identify the relationships significant in social support (received (SSR) and provided (SSP)) and analyze their connections with loneliness and SWB. The subjects, not suffering from dementia, were 60 years and above living in Kathmandu city. The data was analyzed using logistic regression with some confounding variables controlled. The results indicate that loneliness is high and SWB is low amongst Nepalese older adults. SSR from children living together and SSP to spouse, children living together and friends and neighbors reduce loneliness. SSP to children living apart increases SWB-life satisfaction. SSR from children living together and SSP to children (living together and apart) increases SWB-life stability. However, SSP to relatives reduces SWB-life satisfaction and SSR from relatives reduces SWB-life stability in Nepalese older adult men.
