The hazards of sedentary lifestyles

The Canadian Health Measures Survey (CHMS) conducted a study using no less than 4 days of valid data collected from a complete of two,832 adults aged 20 to 79 and 1,608 children/adolescents aged 6 to 19. For scientific validity, the activity level of participants was measured directly using a small device akin to a classy pedometer worn on the topic’s hip for seven days.

Highlights from the survey included:

  • Just over half of all adults accumulate no less than half-hour of moderate-to-vigorous physical activity someday every week, but only 5 per cent of adults manage to build up the really useful 150 minutes through the week.
  • On average, adult men take about 9,500 steps a day, compared with 8,400 for girls. Amongst older adults aged 60 to 79, men averaged 7,900 steps every day, while women averaged 7,000 steps.

Over time, the Harvard School of Public Health has conducted two large studies to quantify the danger of sedentary lifestyle on the event of type 2 diabetes and obesity.

The primary major study (The Nurses’ Health Study) included 50,277 nurses who were aged 30 to 55 and had their health status followed for six years. Of this group, 3757 (7.5%) of them who weren’t obese at first of the study became obese by the tip. There have been also 1,515 recent cases of type 2 diabetes. Adjusting for age, smoking, exercise levels, dietary aspects, and other variables, each 2 hour block of TV watching was related to a 23% increase in obesity and a 14% increase in the danger of diabetes. Researchers estimated that 30% of recent cases of obesity and 43% of recent cases of diabetes might be prevented by adopting a more energetic lifestyle (<10 hours/week of TV watching and ≥half-hour/day of brisk walking).

The second study (The Health Professionals Follow-up Study) included 37,918 health skilled men aged 40 to 75 years whose health status was followed for 20 years. Each 2 hour block of watching TV independent of physical activity was related to a 20% higher risk for Type 2 diabetes. The participants within the study who watched more TV also tended to have unhealthy eating habits (higher intake of processed meat, snacks and sugar-sweetened beverages, and fewer fruits, vegetables and whole grains). This eating pattern was directly related to advertisements and food cues appearing on TV.
