Learning Objective 1: reflect about the importance of using objectives methods as pedometers to measure physical activity in adults with type 2 diabetes to enrich the nursing knowledge.

Learning Objective 2: know about the relationship between physical activity and body composition in order to design specific nursing interventions.

Purpose: To determine physical activity defined as steps/day in adults with type 2 diabetes, and their relationship with body mass index, waist circumference, body fat and visceral fat.

Methods: Correlational study in adults with type 2 diabetes registered in 20 Health Community Centers in Tampico Tamaulipas Mexico. It was used a randomized sampling, a sample size with a confidence of 95%, and a power of 90% (129 participants).  Exclusion criteria were: <19 points in the MMSE, neurological and psychiatric disorders, physical limitation and any problem of senses. For data collection there were used the pedometer New Life Style-2000 by seven days, anthropometric measures as BMI, waist circumference, body fat  and visceral fat, which was measured with Tanita monitor. For data analysis it was calculated central tendency measures, Pearson correlation and, student test.

Results: The average of age was 53.45 ± 9.20, steps/day was 8,108 ± 3655, BMI was 30.57 ± 4.60, waist circumference 101 ± 10.44, body fat 36.85 ± 7.04 and, visceral fat 10.38 ± 4.04. Men had significantly more visceral fat  than women (t  = 4.82,  p < .001). Twenty five percent of participants had low activity (< 5,000 steps/day), 23 % minimums activity (5,000 – 7,499 steps/day), 23 % moderate activity (7,500 – 9,999 steps/day), 16 % were active (10,000 – 12,499 steps/day), and 13 % were very active (> 12,500 steps/day). Steps/day was inversely and significantly correlated with BMI (r = -0.31, p < .001), waist circumference (r = -0.32, p < .001) and visceral fat (r = -0.40, p < .001).

Conclusion: Findings of this research lead suggest that objective measures through pedometers in Mexican diabetic people will permit both researchers and practitioners to have level of ambulatory activity, which can be very useful to design specific interventions to prevent metabolic complications in this population.
