Predictors of Long COVID: older adults, women, and an incomplete COVID-19 vaccination schedule.

Karina Marques Prediger, Ana Cristina Ribeiro La Scaléa, Silvia Carla da Silva André Uehara

PMID 42484298

WHAT IT FOUND

In adults with long COVID in Brazil, older people reported more shortness of breath, women more hair loss, and people with no vaccine doses more chest pain.

These are associations from records, not proof these factors caused symptoms.

Key findings

01Women with long COVID reported hair loss more often than men.

02Adults aged 60 or older reported shortness of breath more often than younger adults.

03People with no vaccine doses reported chest pain more often.

What it does not show

The study used existing medical records, so symptom information may have been incomplete or inconsistent, and symptoms may have been underreported. It was cross-sectional, so it can show associations between age, gender or vaccination status and symptoms, but not cause. It included only people who returned to primary health care with reported symptoms, so people with long COVID who did not seek care were not represented. The sample came from one municipality and 350 adults, so it may not represent other regions or the diversity of Brazil. Many symptom comparisons were made, and some tables show missing data, so individual differences should be read cautiously.

The easy way to misread this

Do not conclude that vaccination prevents long COVID or that unvaccinated people caused their chest pain. The study is cross-sectional and used symptom records, so it shows associations, not cause.
