Table 3.
Between-group comparison of self-reported physical activity measurements and compliance with ACOG recommendations at 28 weeks' gestation, adjusting for baseline data (n = 306)a,b.
| Intervention (n = 153) | Control (n = 153) | ||||||
|---|---|---|---|---|---|---|---|
| Pre | Post | Pre | Post | Mean difference (95% CI) | Odds ratio (95% CI) | P | |
| Light activity (minutes per week) | 71.5 ± 66.8 | 96.8 ± 71.9 | 76.1 ± 63.8 | 84.8 ± 66.3 | 13.3 (-3.1, 29.7) | – | 0.111 |
| Moderate activity (minutes per week) | 59.5 ± 65.4 | 78.1 ± 69.5 | 55.3 ± 62.6 | 50.1 ± 60.1 | 26.5 (11.7, 41.3) | – | 0.001 |
| Vigorous activity (minutes per week) | 11.8 ± 32.3 | 8.0 ± 25.1 | 9.9 ± 26.0 | 3.1 ± 13.9 | 4.0 (-5.9, 8.9) | – | 0.087 |
| MET-minutes per week | 511.4 ± 459.2 | 609.8 ± 448.6 | 487.0 ± 397.5 | 463.9 ± 324.2 | 141.4 (62.9, 219.9) | – | <0.001 |
| Meeting ACOG recommendations [n (%)] | 33 (21.6%) | 36 (24.7%) | 28 (18.3%) | 24 (15.9%) | – | 1.63 (0.89, 2.99) | 0.117 |
Values are means ± SDs; 95% CIs in parentheses, unless specified as [n (%)].
P-values were calculated using analysis of covariance (continuous data) and logistic regression (categorical data) with adjustment for corresponding baseline variables. Data in this table come from participants with complete questionnaires at both 16 and 28 weeks' gestation.
Light Activity (e.g., yoga, golf, easy walking, bowling, beginners aerobics, and light gardening).
Moderate Activity (e.g., fast walking, tennis, badminton, easy swimming, easy cycling, popular and folk dancing, intermediate aerobics, and heavy gardening).
Vigorous Activity (e.g., running, jogging, football, soccer, squash, basketball, vigorous swimming, vigorous long-distance cycling, and advanced aerobics).
MET-minutes formula: 8·0 × vigorous activity + 4·0 × moderate activity + 3·3 × light activity.
Bold value indicate significance level of <0.05.
