Sitting Time and Sedentary behaviors

Have been associated with adverse health outcomes including Obesity

,diabetes and cardiovascular diseases(CVD within nonHispanic white

populations.

Similar associations have not been described within Hispanic

Populations despite their high CVD risk profile .

Most adults in U.S . do not meet daily recommended amounts of

Physical activity and engaged in large amounts of sedentary behaviours

As commuting by automobile,sitting at work and watching TV at home.

Data collected between 2004 and 2010 were analyyzed in late 2010 with

Regression analysis evaluated associations between self --,reported daily sitting hours

And disease outcomes, controlling for demographics,employment status ,family

Disease history ,and light ,moderate and strenous physical activity.

Results. Participants were mostly females (81.1)percent

Mexican origin adults .Sitting time was associated with increased odds

Of being obhaving diabetes and having hypertension ,but not cholesterol.

Adjusted obese ds ratios of participants who reported sitting greater than four hours

/Day compared to those sitting for 1-2hours/day were for obesity OR =1.55(95%CI

1.39.1.73),P,,≤.001 for diabetes OR =1.29,(95%CI.1.09.1.52). p,=.003for hypertension OR

1.17 (95%CI,1.01,1.37),p=.041

An Odds ratio (OR)is a measure of association between an out come

If OR ,=1 Exposure does not affect odds of out come.

If OR =>1 Exposure is associated with higher odds of outcome

If OR <1 Exposure is associated with lower odds of outcome

Sitting time is not associated with increased odds for having high cholesterol.
