What are reasons behind loneliness in men as per a research?

Loneliness is highest among men in their late 40s but it also occurs at other times, as per Australian researchers. Increased social isolation, romantic partnership dissolution, having a long-term disability, and stronger beliefs that the man, rather than the woman, should be the breadwinner, are associated with greater loneliness. Men who were in insecure jobs experienced more loneliness.
