Objective:
To assess whether pedometers and text messaging increase physical activity in adolescents with type 1 diabetes.
Research Design And Methods:
A 12-week randomized controlled trial was conducted. A total of 78 subjects participated in the trial (mean +/- SD age 14.4 +/- 2.37 years, 36 [47%] male). Intervention participants wore an open pedometer and received regular motivational text messages. Control participants received usual care. Primary outcomes were daily step count (4-day closed pedometer) and physical activity questionnaire.
Results:
Baseline median step count was 11,063 steps/day (range 1,541-20,158). At 12 weeks, mean daily step count reduced by 840 (95% CI -1,947 to 266) in the control group and by 22 (-1,407 to 1,364) in the intervention group (P = 0.4). Mean self-reported moderate or vigorous physical activity increased by 38.5 min/week in the control group and by 48.4 in the intervention group (P = 0.9).
Conclusions:
A 12-week intervention using pedometers and text messaging as motivational tools in adolescents with type 1 diabetes did not increase physical activity.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
