Brief summary
This is a randomized controlled trial study. We evaluate effectiveness of maternal exercise on anxiety during normal pregnancy compared to those who receive antenatal care regularly. We plan to recruit 220 healthy pregnant women over the age of 18 in Shenzhen and to use a standard maternal exercise from Korea as intervention.
Interventions
BEHAVIORALmaternal exercise
The maternal exercise is broadly practiced by pregnant women in China. It is designed by a team led by Shen Shanmei, a professor of Maternity Exercises at Department of Obstetrics and Gynecology of First Hospital in Korea.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline of State Anxiety at 32 Weeks of Gestation | The participants are examined between 12 and 16 weeks of gestation (baseline visit) and at gestation week 32 (after the intervention). | We use state anxiety subscale of State-Trait Anxiety Inventory (STAI) as the measure of anxiety severity. The STAI comprises two-self report scales for measuring two distinct anxiety concepts, the State anxiety and Trait anxiety. Both scales contain 20 statements that ask the respondent to describe how she feels at a particular moment (state anxiety) or how she generally feels (trait anxiety). State anxiety is conceptualized as a transitory emotional state, where as trait anxiety refers to relatively stable individual differences in proneness to anxiety. The respondents are required to rate themselves on a four point likert scale 'not at all' to 'very much so on' various anxiety related symptoms which they experience in the past weeks for the state scale or how they generally feel for the trait scale. STAI is widely used and has been shown to have high reliability and validity with a Cronbach's alpha of 0.88 and 0.83 for state (STAI-I) and trait anxiety (STAI-II) respectively. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline of Depressive Symptom at 32 Weeks of Gestation | The participants are examined between 12 and 16 weeks of gestation (baseline visit) and at gestation week 32 (after the intervention). | We use Beck Depression Inventory second edition (BDI-Ⅱ) as the measure of depressive symptom severity. The BDI-II is a 21-item self-report measure of common depressive symptoms. Each item has four possible responses, and higher total scores are indicative of a greater number and severity of depressive symptoms. Scores ranging from 0 to 13 indicate minimal/no symptoms, 14-19 indicate mild depression, 20-28 indicate moderate depression, and 29-63 indicate severe depression. |
| Change from Baseline of Pain at 32 Weeks of Gestation | The participants are examined between 12 and 16 weeks of gestation (baseline visit) and at gestation week 32 (after the intervention). | We use Brief Pain Inventory (BPI) as the measure of the severity of pain. The pain intensity section of the BPI is composed by four items that are scored from 0 (no pain) to 10 (worst pain), while the functional interference section is composed by seven items that are scored from 1 (no interference with activities of daily living) to 10 (total interference). The severity index is calculated on the basis of the mean of the four pain intensity items, and interference index is calculated from the mean of the seven pain interference items. |
