Trial results from the "Modeling the Epidemiologic Transition Study" investigating obesity were posted on ClinicalTrials.gov on 2025-09-17. The study observed varied changes in body weight across different populations, with mean increases up to 2.33 kilograms (kg) in Seychelles women.
Background
Obesity is a complex and growing global health concern. This study investigated the ecological hypothesis that reduced activity energy expenditure (AEE) contributes to rising obesity rates. Understanding the relationship between AEE, adiposity, and diabetes is crucial for public health strategies.
Trial design
The completed "Modeling the Epidemiologic Transition Study" enrolled 2506 participants, focusing on Obesity and Diabetes. The project aimed to assess the relationship between individuals' activity energy expenditure (AEE) and adiposity/diabetes-related hormones, testing the hypothesis that declining AEE levels drive increasing obesity rates in various societies using objective measures.
Key results
The study measured "Change in Body Weight" across various participant groups:
- For Ghanaian Men, the mean change in body weight was 0.69 kilograms (kg) (Standard Deviation 3.15).
- For South African Men, the mean change in body weight was 0.76 kilograms (kg) (Standard Deviation 4.67).
- For Jamaican Men, the mean change in body weight was 0.20 kilograms (kg) (Standard Deviation 3.90).
- For Seychelles Men, the mean change in body weight was 0.81 kilograms (kg) (Standard Deviation 5.22).
- For United States Men, the mean change in body weight was 0.11 kilograms (kg) (Standard Deviation 5.99).
- For Ghanaian Women, the mean change in body weight was 1.94 kilograms (kg) (Standard Deviation 4.10).
- For South African Women, the mean change in body weight was 2.15 kilograms (kg) (Standard Deviation 6.82).
- For Jamaican Women, the mean change in body weight was -0.11 kilograms (kg) (Standard Deviation 3.72).
- For Seychelles Women, the mean change in body weight was 2.33 kilograms (kg) (Standard Deviation 4.27).
- For United States Women, the mean change in body weight was 0.08 kilograms (kg) (Standard Deviation 6.60).
What this means
This study reveals varied body weight changes across populations and genders. Women in Ghana, South Africa, and Seychelles showed mean weight increases of 1.94 kg, 2.15 kg, and 2.33 kg, respectively. Jamaican women experienced a slight mean decrease of -0.11 kg, while men generally had smaller increases. These findings underscore diverse factors influencing weight changes across groups. The study's focus on activity energy expenditure offers insights for public health interventions and research into population-specific weight dynamics.
