"However, one in 20 men and one in 40 women aged 35 and over reported new partner(s) while overseas in the past five years.
"These proportions are likely to increase as older people maintain good health, have the financial means to travel and are now more likely to experience partnership breakdown, and so older age groups should also be considered for health promotion messages by health professionals when consulting for travel advice."
The study, published in the journal Sexually Transmitted Infections, examined more than 15,000 responses to the British National Survey of Sexual Attitudes & Lifestyles carried out between 2010 and 2012.
More than 12,500 of the 16- to 74-year-olds polled said they had at least one sexual partner within the preceding five years.
Of these, 9.2 per cent of men and 5.3 per cent of women reported new sexual partners while overseas.
The authors found that those who reported new partners while abroad were also more likely to engage in "sexual risk" behaviours such as unprotected sex.
