Can a 12-Week lifestyle program lower harmful chemical levels?
NCT ID NCT07773233
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether a 12-week structured program can help women aged 18-49 reduce their exposure to endocrine-disrupting chemicals (EDCs), which are found in everyday products and may affect reproductive health. Participants are randomly assigned to either the program or a control group. The program includes education, goal setting, self-monitoring, and WhatsApp support. Researchers measure urine levels of bisphenol A (BPA) and phthalates before and after to see if the program makes a biological difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A 12-week structured behavioral change program based on Pender's Health Promotion Model, including education, goal setting, self-monitoring, and WhatsApp support.
- What this could lead to
- If effective, this program could offer a practical, low-cost way for women to reduce their exposure to chemicals that may affect reproductive health.
- What could go wrong
- The trial is relatively small and relies on self-reported behavior changes, which may not translate into lasting reductions in chemical exposure. Individual results may vary.

Inclusion Criteria: * A total of 108 women aged 18-49 years will be randomly allocated in a 1:1 ratio to an intervention or control group. The intervention group will participate in a 12-week structured behavioral change program based on Pender's Health Promotion Model. The program will include education, goal setting, action planning, self-monitoring, problem solving, social support, behavioral rehearsal, environmental restructuring, and digital reinforcement messages delivered via WhatsApp Exclusion Criteria: * At the beginning of the study, women who are pregnant or breastfeeding, menopausal, have cognitive or psychiatric disorders severe enough to interfere with active participation in the study or independent completion of the data collection instruments, have a diagnosed serious endocrine disorder that could significantly affect the endocrine system (e.g., pituitary disorders or Cushing's syndrome), or have participated in a structured educational program on endocrine-disrupting chemicals within the previous six months will be excluded from the study
