Over the past 15 years or so sitting has been connected with heart disease and diabetes(糖尿病). But is sitting really that risky?In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.We studied sitting habits of 4. 811 middle-aged people, who didnt have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetesThis is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.For people who are physically inactive, though, the storys different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obeseThats not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.For example, sitting down at work isnt strongly connected with long-term health risks, Perhaps thats because higher position jobs needs more sitting, and higher socioeconomic（社会经济） position is connected with a lower risk of disease. Its a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to( a)be of lower socioeconomic positions, unemployed, have poorer mental(（精神上的） health, eat unhealthy foods and face more unhealthy food advertising.1Why is sitting called the“ new smoking”？A.
