Married people with higher incomes are less likely to suffer a broken bone in old age, according to new research.
The study by scientists from the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU) at the University of Southampton, published in Osteoporosis International, investigated whether differences in socioeconomic status, represented by income and marital status, were associated with fracture risk.
Researchers from the Universities of Southampton, Oxford and Bristol, as well as Aalborg and Southern Denmark, analysed data from 189,838 patients who had broken bones, compared with the same number of patients who had not experienced a broken bone, drawn from the Danish population.
The team concluded that higher income was linked to the reduced chances of experiencing a fracture of the hip, upper arm or wrist compared with average income, and that those who were married had less than half the likelihood of sustaining a fracture compared with those who were single.
Professor Nicholas Harvey, professor of rheumatology and clinical epidemiology at the MRC LEU, said: "There are over 500,000 broken bones due to osteoporosis (thinning of the bones) annually in the UK at a cost of £4.4 billion and with an immense impact on health and survival.
"Given that we are in a period of increasing social inequality, our findings of differences in fracture risk by income and marital status provide further impetus for the need to ensure adequate provision of healthcare across all social strata, and to address the factors underlying these disparities.
"We don't know for certain how being married protects against fracture, but studies show that marriage is protective against a range of adverse health outcomes, possibly through various factors related to physical and mental health, security and economic status."
Professor Cyrus Cooper, director of the MRC LEU, said: "This work forms part of a larger programme of investigations into influences, across the whole of the lifecourse, on the risk of osteoporotic fracture and other musculoskeletal conditions such as osteoarthritis and sarcopenia, and demonstrates the huge value of UK collaboration with international partners in the use of these large datasets."
