Promotion of a healthy lifestyle among 5-year-old overweight children: health behavior outcomes of the 'Be active, eat right’ study

Table 3 Baseline and follow-up means of playing outside and watching television per day, and regression coefficients of the intervention condition compared with the control condition

	n	Intervention condition	n	Control condition	Beta coefficient (95% CI)¹	Beta coefficient (95% CI)²
Outside play, mean (SD)
Baseline	315	161.84 (106.66)*	264	160.50 (100.91)
Follow-up	153	135.93 (91.32)*	140	123.82 (76.34)	15.00 (-4.14; 34.15)	8.22 (-15.77; 32.22)
Watching television, mean (SD)
Baseline	318	103.93 (74.05)	270	105.94 (66.57)
Follow-up	156	102.64 (61.67)	142	104.34 (54.81)	-1.56 (-14.56; 11.44)	-1.56 (-14.57; 11.45)

¹Beta coefficient and 95% confidence interval (95% CI) from regression model evaluating the difference between intervention and control condition on the outcome at follow-up, corrected for baseline value of the outcome, time between measurements and age of the child at baseline.
²Beta coefficient and 95% confidence interval (95% CI) from multilevel regression model evaluating the difference between intervention and control condition on the outcome at follow-up, corrected for baseline value of the outcome, time between measurements and age of the child at baseline.
Note: Bold printed numbers indicate statistically significant within-group change; within-group change of behavior from baseline to follow-up was evaluated using cluster-adjusted intercept only regression analysis, asterisks indicates significance level: *p < 0.05.
