Every hour per day watching television increases the risk of diabetes – El Universal – Colombia

Each time a person spends sitting watching television every day increases the risk of developing diabetes by 3.4 percent, according calculates a study published in Diabetologia ‘, the journal of the European Association for the Study Diabetes. This research on the effects of sedentary or spend much time sitting in the risk of diabetes was performed by Dr. Bonny Rockette-Wagner and Andrea Kriska, University of Pittsburgh, USA, and colleagues.

In this new research, the authors used data from participants in the study Program Diabetes Prevention (DPP), released in 2002 and funded by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK, for their acronym in English), a division of the National Institutes of Health (NIH, for its acronym in English) Americans.

This study enrolled 3,234 adult Americans are overweight (1996-1999) of at least 25 years of age in order to delay or prevent type 2 diabetes in people at high risk with either metformin or a drug intervention in their lifestyle. Previous works have already suggested that intervene in lifestyle is successful in reducing the incidence of diabetes and achieve the goals of a weight loss of 7 percent and 150 minutes per week of moderate-intensity activity (walking by step light).

What is unknown is whether this change in lifestyle had any impact on time spent sitting (sedentary). The above results suggest that it is unclear whether interventions focused on increasing physical activity also reduces the time spent sitting still. This new work examined whether the intervention of the lifestyle of the DPP, which has proven effective in increasing physical activity, also reduced the hours they spend sitting recognizes that, and the effect of sedentary behavior in developing diabetes.

Before the intervention, the total time spent watching television was not significantly different between the placebo, metformin and lifestyle of the DPP (about 140 minutes per day the three groups). The total daily time spent sitting at work and time watching television was not significantly different between groups (between 410 and 423 minutes per day) at baseline.

For participants lifestyle, a reduction was observed in the time they said spend watching television throughout follow-up for all subgroups of participants, including age, gender, employment status, race / ethnicity, state obesity or those who achieve the goal of weight and / or activity.

Similarly, the lifestyle group had the largest reduction in the average time spent watching television and sitting time at work during the monitoring period. The average reduction combining time sitting watching TV and time sitting at work was 9, 6, and 37 min / day for placebo, metformin and lifestyle groups, respectively.

Then The authors analyzed the impact of sedentary behavior over time on the incidence of diabetes. For participants in all treatment groups, the risk of developing diabetes increased by about 3.4 percent for every hour spent watching television after adjusting for age, sex, treatment group and leisure time devoted to physical activity.

“It is likely that an intervention program in the lifestyle that incorporates a specific goal of reducing sedentary time may result in major changes in this attitude and probably more improvements in health which are shown here, “predicts Kriska.
