Association of self-reported physical fitness with pregnancy related symptoms the gestafit project

Abstract

We explored the association of physical fitness (PF) with pregnancy-related symptoms, at the 16th and 34th gestational weeks (g.w.). The International Fitness Scale and the Pregnancy Symptoms Inventory were employed to assess self-reported PF and pregnancy-related symptoms, respec-tively. At the 16th g.w. greater self-reported overall PF was associated with lower incidence of uri-nary frequency (p = 0.020); greater overall PF, cardiorespiratory fitness (CRF), muscular strength and speed-agility were associated with lower incidence of tiredness-fatigue (all, p < 0.05); greater overall PF and speed-agility were associated with lower incidence of poor sleep (both, p < 0.05); greater CRF and flexibility were associated with lower limitations by tiredness-fatigue (both, p < 0.05); and greater flexibility was associated with lower limitations by poor sleep (p = 0.021). At the 34th g.w. greater self-reported overall PF, CRF and muscular strength were associated with lower incidence of tiredness-fatigue (all, p < 0.05); greater CRF was associated with lower incidence of poor sleep (p = 0.019); and, greater flexibility was associated with lower incidence of increased vaginal discharge (p = 0.023). Adequate levels of PF, especially CRF, may help women to cope with the most endorsed pregnancy-related symptoms and its limitations, especially tiredness-fatigue and poor sleep.
