PMS and PMDD statistics

PMDD statistics

How common is PMDD? The numbers

PMDD affects about 1.6% of women and girls in community studies that confirmed it with daily symptom tracking over two cycles, 3.2% across all studies with a confirmed diagnosis, and about 7.7% on a provisional diagnosis (Reilly et al., 2024). Broader systematic reviews put the range closer to 3% to 8% worldwide, depending on study method. PMS, a separate and far more common experience, affects close to half of women globally.

How common is PMS? The numbers

PMS is common, but there's no single worldwide percentage. Published estimates range from roughly half of women in some studies to far lower in others, depending on how symptoms are defined and measured. A systematic review of Ethiopian studies, for example, found a pooled prevalence of 53%.

PMDD and divorce: what the studies measured

No large study has tracked a population-level PMDD divorce rate, so there's no reliable percentage to cite. What's documented is that PMDD is linked to real strain on relationships, including couple burnout and reduced relationship functioning, and that treatment can measurably improve that domain.

How PMS changes with age: the data

PMS prevalence estimates range from about 5% to 53%, depending on how strictly a study defines it, not mainly on age. A Swiss guideline puts PMDD, the more severe diagnosis, at 3 to 8% of women. Studies rarely break results down by exact age, since most group together everyone of reproductive age, from the teens to the late forties.

Statistic

PMDD comorbidity: which conditions overlap most?

PMDD comorbidity is common. Large reviews find that comorbidity rates were consistently high among people already diagnosed with a mood disorder, depression or bipolar. Within bipolar disorder specifically, the subtype most often linked to PMS and PMDD is bipolar II. The share swings depending on whether a study looks at a psychiatric clinic or the general population, and how strictly premenstrual disorders were defined.

Perimenopause statistics

Perimenopause depression statistics: how common is it?

Perimenopause depression statistics don't add up to one confirmed percentage. Studies measure depression differently and in different groups of women. The clearest figure comes from an 8-year study, where high depressive symptom scores were over four times more likely during the menopause transition than before it (OR 4.29, Archives of General Psychiatry, 2006).
