Exercise linked to lighter mood through menopause

Menopause is a period when depression and depressive symptoms become markedly more common, and they can substantially impair quality of life. Physical activity has repeatedly been reported to help prevent and treat depression in general populations, but whether that benefit holds specifically for menopausal women — and whether it depends on how hard, how often or in what form the exercise is done — has been less clear. This meta-analysis set out to pool the randomised evidence on leisure-time physical activity and depression in this specific group.

The researchers searched nine databases, including PubMed, Embase, Cochrane Library, Web of Science, PsycINFO, CINAHL Plus and the Chinese-language CNKI, VIP and WanFang, for randomised controlled trials of leisure-time physical activity in menopausal women with depression or depressive symptoms as outcomes. Seventeen studies met the criteria. Effects were pooled as weighted or standardised mean differences, heterogeneity was tested, sensitivity analyses were run, and subgroup analyses examined depression severity, exercise intensity, exercise form, intervention duration, supervision, sample size and geographical region.

Exercise alleviated depressive symptoms in menopausal women, with a pooled standardised mean difference of −1.23 (95% CI −2.21 to −0.24). On specific instruments, exercise was associated with reductions of −5.76 points on the Center for Epidemiologic Studies Depression Scale (95% CI −6.63 to −4.89) and −6.86 points on the Self-Rating Depression Scale (95% CI −9.24 to −4.49). Strikingly, results were similar across subgroups: depression degree, exercise intensity, form, intervention duration, supervision status, sample size and region made little difference to the pattern.

The finding is consistent with the broader literature showing physical activity benefits mood, and it extends that evidence to menopausal women specifically. The consistency across subgroups suggests the effect is not confined to any single exercise prescription, though the wide confidence interval on the main pooled estimate points to considerable variation between studies. The authors are explicit that further high-quality trials are needed to confirm the findings and to pin down the specific effects of different types of physical activity in this population.

For women going through menopause, this is a reason to think that leisure-time physical activity — in essentially any form that appeals — is associated with meaningfully lighter depressive symptoms. The fact that intensity, format and programme length made little difference in these trials suggests the choice of activity may matter less than doing something at all. This is pooled trial evidence rather than a guarantee for any individual, and the study's authors themselves want stronger trials before drawing firmer conclusions.
