Treatment and study plan

Pregnancy Weight Management Counseling

Behavioral

Participants will receive in-person pregnancy weight management counseling provided by healthcare professionals. The counseling will provide individualized guidance on pregnancy weight management and related health behaviors according to participants' needs.

Primary outcomes

  1. Change in body weight

    Time frame: Baseline and after 8-12 weeks of intervention

    Body weight will be measured in kilograms before and after the pregnancy weight management intervention.

  2. Change in technology acceptance

    Time frame: Baseline and after 8-12 weeks of intervention

    Technology acceptance will be assessed using the 23-item Technology Acceptance Model questionnaire. Each item is rated from 0 (strongly disagree) to 4 (strongly agree). Higher scores indicate greater acceptance of the pregnancy weight management application.

Secondary outcomes

  1. Change in exercise self-efficacy

    Time frame: Baseline and after 8-12 weeks of intervention

    Exercise self-efficacy will be assessed using the exercise-related items of the Diet and Exercise Daily Life Self-Efficacy Scale. Each item is rated from 0 to 4, with higher scores indicating greater exercise self-efficacy.

  2. Change in dietary self-efficacy

    Time frame: Baseline and after 8-12 weeks of intervention

    Dietary self-efficacy will be assessed using the dietary-related items of the Diet and Exercise Daily Life Self-Efficacy Scale. Each item is rated from 0 to 4, with higher scores indicating greater dietary self-efficacy.
