Randomized Controlled TrialEffects of a weight maintenance program with or without exercise on the metabolic syndrome: a randomized trial in obese men.
Weight maintenance (WM) after weight reduction (WR) is difficult, but increased physical activity may help. We studied whether adding exercise to diet counseling decreases the occurrence of the metabolic syndrome (MBO). ⋯ Adding structured exercise to diet counseling did not alleviate MBO better than diet only. However, the occurrence of MBO was reduced in all groups at the end.

Precision and accuracy of an ankle-worn accelerometer-based pedometer in step counting and energy expenditure.
Walking is a widely used approach to increase physical activity levels in obese patients. In this paper, we investigate the precision and accuracy of an ankle-worn dual-axis accelerometer (Stepwatch) and investigate its potential application as a predictor of energy expenditure. ⋯ The counts from the Stepwatch were virtually identical to the manual counts from a trained investigator and provided a reliable predictor of walking energy expenditure.

Poverty is a predictor of non-communicable disease among adults in Peruvian cities.
Rapid health and nutrition transitional changes are resulting in greater prominence of non-communicable disease (NCD) in Latin America, particularly among the poor. ⋯ The high prevalence of NCD in urban areas of Peru is not only associated with excess body weight, but also with poverty itself. The greater burden of NCD in the poorest areas of society requires a better understanding of causal determinants and may have implications in terms of public health policies and interventions.
