Objective: To evaluate the effect of replacing 1 h/week of watching television with
1 h/week of light to moderate (LMPA) or vigorous physical activity (VPA) before and
during pregnancy on the risk of gestational diabetes mellitus (GDM).
Methods: A case–control study was conducted in pregnant women. Physical activity
and television watching before and during pregnancy were assessed using the
Paffenbarger Physical Activity Questionnaire. Each type of activity was classified according
to intensity (metabolic equivalent of task; MET): less than 6 METs is LMPA, 6
METs or more is VPA. The duration of physical activity and watching television was
calculated, and logistic regression models were used to estimate adjusted odds ratios
(aOR) and 95% confidence intervals for their association with GDM risk. The isotemporal
substitution model was used to calculate the effect of replacing 1 h/week of
watching television with the same duration of physical activity.
Results: The GDM cases (n = 290) spent less time performing VPA than controls without
GDM (n = 1175) and more time watching television during pregnancy (P < 0.05). During
pregnancy, the risk of GDM increased for each hour of watching television (aOR = 1.02;
95% confidence interval 1.00–1.03). Women who spent more time watching television
during pregnancy were likely to develop GDM (aOR>14 h/week vs. 0–6 h/week = 2.03;
95% confidence interval 1.35–3.08). Replacing 1 h/week of watching television with
1 h/week of VPA during pregnancy could decrease the chance of developing GDM
(aOR = 0.66; 95% confidence interval 0.43–1.00).
Conclusions: A simple change of 1 h/week of watching television for 1 h/week of VPA
in pregnant women may reduce the risk of GDM considerably
