TI  - Activity, adiposity and weight change in Jamaican adults.
PG  - 398-403
AB  - OBJECTIVE: Populations in developing countries are particularly vulnerable to the 
      development of obesity in the period of rapid transition to a more modernized 
      lifestyle. We sought to determine the relationship between activity energy 
      expenditure (AEE), adiposity and weight change in an adult population undergoing 
      rapid socio-economic transition. METHODS: Total daily energy expenditure (TDEE) 
      was measured using the doubly labelled water method, resting energy expenditure 
      (REE) using indirect calorimetry and AEE calculated as the difference between 
      TDEE and REE, in adults from a working class community in Spanish Town, Jamaica. 
      During six years of follow-up, weight was measured between one and four times. 
      Mixed effects regression modelling was used to test for association between 
      components of the energy budget and weight change. RESULTS: Men (n = 17) weighed 
      more but women (n = 18), had significantly more body fat, 38.5% vs 24.5%, 
      respectively (p < 0.01). Men had higher levels of EE, particularly AEE after 
      adjustment for body weight, 66.3 versus 46.4 kJ/kg.d for men and women, 
      respectively (p < 0.001). At baseline, adjusted AEE was inversely associated with 
      body fat in men and women, r = -0.46 and r = -0.48, respectively (p < 0.05). Mean 
      rate of weight change was + 1.1 and + 1.2 kg/year for men and women, 
      respectively. No component of EE, ie TDEE, REE or AEE, significantly predicted 
      weight change in this small sample. CONCLUSIONS: These results suggest an 
      important role for AEE in maintaining low levels of adiposity. The lack of 
      association between EE and weight change, however, suggests populations in 
      transition are at risk of obesity from environmental factors (eg dietary) other 
      than simply declining physical activity levels.
