The goal of this clinical trial is to evaluate whether a structured nutritional education intervention can improve gestational weight gain outcomes and related maternal and neonatal health indicators in women with uncomplicated pregnancy. The main question it aims to answer is whether a group-based nutritional education program increases the proportion of women achieving gestational weight gain within Institute of Medicine (IOM) recommended ranges compared with standard prenatal care.
Researchers will compare a structured nutritional education intervention group to a control group receiving routine prenatal care and a nutritional information brochure to see if the intervention improves gestational weight gain within recommended ranges and affects maternal and neonatal outcomes.
Participants in the intervention group will:
* Attend three weekly group-based nutritional education sessions delivered by trained healthcare professionals
* Attend one practical cooking (show-cooking) session
Participants in the control group will:
* Receive routine prenatal care and a written nutritional information brochure
* Be followed from early pregnancy until 8 weeks postpartum
All participants (including control group) will:
* Record body weight regularly throughout pregnancy using a telemedicine system
* Complete questionnaires on dietary intake and quality of life at multiple time points
* Undergo assessments of body composition and urinary biomarkers of oxidative stress during pregnancy
