Mean waist circumference and BMI in 1986, 2001 and 2011, and change in waist/BMI between 2001 & 2007, and 2001 & 2011 in different TV time groups, with Tukey-Kramer corrected pairwise TV group comparisons.

n =  All available observations for the variable in question.
Waist  =  Waist circumference.
BMI =  Body mass index.
Constantly low  =  TV time ≤1 h/day in 2001, 2007 and 2011.
Constantly moderate  =  TV time >1 h, but <3 h/day in 2001, 2007 and 2011.
Constantly high  =  TV time ≥3 h/day in 2001, 2007 and 2011.
Increased  =  TV time increased with ≥1 h/day between 2001 and 2011.
Decreased  =  TV time decreased with ≥1 h/day between 2001 and 2011.
* =  adjusted by sex, age, physical activity, energy intake, smoking, and Waist or BMI in 2001.
Tukey-Kramer adjusted pairwise comparisons:
1 = statistically significant difference with Low group (p<0.05).
2 = statistically significant difference with Moderate group (p<0.05).
3 = statistically significant difference with High group (p<0.05).
4 = statistically significant difference with Increase group (p<0.05).
