Is this trial a fit for you?

Likely a good fit

Women aged 18–45 in their third trimester with the ability to give informed consent, a singleton low-risk pregnancy, and who are followed at Gebze Fatih State Hospital are ideal candidates.

Probably not a fit

Women with high-risk or multiple pregnancies, chronic systemic/neurological/orthopedic diseases, or those outside the third trimester are unlikely to benefit from participation or be eligible.

What this trial studies

This is a prospective observational study enrolling pregnant women in their third trimester who are followed at Gebze Fatih State Hospital and referred to the Exercise Therapy Laboratory at Bezmialem Vakıf University. Participants provide informed consent and complete a demographic form along with the Pregnancy Physical Activity Questionnaire (PPAQ), a nutritional status assessment, and a pregnancy-related anxiety questionnaire during face-to-face visits. The study will analyze which of these three factors shows the strongest association with excessive gestational weight gain. No interventions are given; the study aims to compare the relative contributions of activity, diet, and anxiety to weight gain during pregnancy.

Why it matters

Potential benefit: If successful, the findings could help clinicians focus prevention efforts on the factor most strongly linked to excessive gestational weight gain, improving maternal and neonatal outcomes.

How similar studies have gone: Previous studies have linked physical activity, nutrition, and pregnancy anxiety separately to gestational weight gain, but few prospective studies have directly compared all three factors head-to-head, so this approach is relatively uncommon.
