Nearly all female university students in this study from Uganda — 97.8% of 275 participants — reported at least one menstrual disorder, yet only 4.4% thought their periods were abnormal. Premenstrual symptoms were the most common issue, affecting 93.8% of students, with depression and mood changes reported by over 60%. Painful periods (dysmenorrhea) affected 63.6% of participants, with about a quarter describing the pain as severe.
Both premenstrual symptoms and painful periods were linked to meaningfully lower quality of life scores. Premenstrual symptoms had the strongest negative effect on how students experienced their environment — things like financial resources, safety, and access to health care. Painful periods significantly lowered quality of life in the psychological, social, and environmental areas of their lives. Among the 10.9% of students who missed classes due to menstrual problems, every single one had dysmenorrhea and nearly all had premenstrual symptoms.
One striking finding is how normalized menstrual suffering was among these students. Over half considered menstrual pain a normal part of life, and fewer than 14% had ever consulted a doctor about a menstrual problem. This suggests many people may be enduring treatable symptoms without seeking help — a pattern that likely extends beyond this particular group.
While this study looked at premenstrual symptoms broadly rather than diagnosing PMDD specifically, the high rates of premenstrual mood changes and their measurable impact on daily life reinforce the importance of recognizing and addressing premenstrual conditions. The findings highlight that premenstrual symptoms can significantly affect well-being and daily functioning, even when the people experiencing them consider those symptoms to be simply part of having a period.
Key findings
- 97.8% (269/275) of participants reported at least one form of menstrual disorder
- Premenstrual symptoms were the most common disorder at 93.8% (N=258), followed by dysmenorrhea at 63.6% (N=175), irregular menstruation at 20.7% (N=57), frequent menstruation at 7.3% (N=20), and infrequent menstruation at 3.3% (N=9)
- Dysmenorrhea significantly reduced QOL scores in psychological (56.2 vs 60.4, p<0.001, d=0.377), social (51.6 vs 59.7, p<0.001, d=0.696), and environmental domains (45.9 vs 50.3, p<0.001, d=0.504)
- Premenstrual symptoms significantly reduced QOL in the environmental domain (46.7 vs 58.8, p<0.001, d=1.212)
- 10.9% (30/275) of participants missed classes in the preceding 2 months due to menstrual problems; 100% of those who missed classes had dysmenorrhea and 93.3% had premenstrual symptoms
- Only 4.4% of participants perceived their menstruation as abnormal despite 97.8% reporting a menstrual disorder, and only 13.8% consulted a medical doctor for menstrual problems
Methods, briefly
Cross-sectional study using a self-administered questionnaire among female undergraduate students at Makerere University College of Health Sciences, Uganda. N=275 included in analysis (96% response rate from 306 approached). Quality of life was assessed using the WHO QOL-BREF instrument across four domains (physical, psychological, social, environmental). Statistical analysis used t-tests and ANOVA with Cohen's d effect sizes. Students on hormonal contraception, pregnant, or lactating were excluded.
Limitations to keep in mind
- Confounding factors affecting QOL scores (e.g., stress, socioeconomic factors) were not controlled for
- Recall bias as participants self-reported menstrual experiences retrospectively
- Menstrual disorders were not clinically diagnosed; diagnosis relied solely on self-report questionnaires
- The WHO QOL-BREF was not validated in Uganda specifically, though it was validated in Zimbabwe
- Single-center study limited to health sciences students, which may limit generalizability
- Students who missed classes due to menstrual problems may not have been captured in the study
