Women Working in Night Shifts Are on Higher Risk of Early Menopause

For the study, the team studied more than 80,000 nurses who worked at least in the night shifts in a month for over 22 years in addition to day and evening shifts

Women who work in night shifts, even occasionally, are at an increased risk of early menopause, which can heighten the possibility of developing cardiovascular disease, osteoporosis and memory problems, finds a new study.

The study showed women who had done continued night shifts for 20 months or more in the preceding two years had a nine per cent increased risk of early menopause, the Daily Mail reported. If they had done rotating night shifts for more than 20 years, the risk rose to 73 per cent.

“For women who went through menopause before the age of 45, shift work seemed to be particularly important. This could be due to disruption of their circadian rhythms, stress or fatigue, although more research is needed,” lead author David Stock, from the University of Dalhousie in Canada, was quoted as saying.

An early menopause could also come from the stress of working late at night, as stress hormones are believed to disrupt sex hormones like oestrogen. This could also increase the chance that a woman stops ovulating, according to the study published in the journal Human Reproduction.

Previous evidence suggests working in ‘high-strain’ jobs and those with ‘difficult schedules’ is linked to earlier menopause.

Premature Menopause More Likely to Increase Health Problems After 60

Compared with women who experienced menopause at the age of 50-51 years, women with premature menopause were twice as likely to develop multimorbidity by the age of 60, and three times as likely to develop multimorbidity from the age of 60 onwards

Women who experience premature menopause are almost three times more likely to develop multiple, chronic medical problems in their 60s, says a new study.

It is known already that premature menopause, occurring at the age of 40 or younger, is linked to a number of individual medical problems in later life, such as cardiovascular disease and diabetes.

However, there is little information about whether there is also an association between the time of natural menopause and the development of multiple medical conditions known as multimorbidity.

For the findings, published in the journal Human Reproduction, researchers at the University of Queensland followed more than 5,000 women aged 45 to 50 from 1996 until 2016.

“We found that 71 per cent of women with premature menopause had developed multimorbidity by the age of 60 compared with 55 per cent of women who experienced menopause at the age of 50-51,” said study researcher Xiaolin Xu from Zhejiang University in China.

“In addition, 45 per cent of women with premature menopause had developed multimorbidity in their 60s compared with 40 per cent of women who experienced menopause at the age of 50-51,” Xu added.

The women responded to the first survey in 1996 and then answered questionnaires every three years (apart from a two-year interval between the first and second survey) until 2016.

The women reported whether they had been diagnosed with or treated for any of 11 health problems in the past three years: diabetes, high blood pressure, heart disease, stroke, arthritis, osteoporosis, asthma, chronic obstructive pulmonary disease, depression, anxiety or breast cancer.

Women were considered to have multimorbidity if they had two or more of these conditions.

During the 20 years of follow-up, 2.3 per cent of women experienced premature menopause and 55 per cent developed multimorbidity.

Compared with women who experienced menopause at the age of 50-51 years, women with premature menopause were twice as likely to develop multimorbidity by the age of 60, and three times as likely to develop multimorbidity from the age of 60 onwards.

“Our findings indicate that multimorbidity is common in mid-aged and early-elderly women,” said Indian-origin researcher and study senior author Gita Mishra.

“We also found that premature menopause is associated with a higher incidence of individual chronic conditions,” Xu added. (IANS)
