The Influence of Age, Sex and Body Mass Index on the Effectiveness of Brisk Walking for Obesity Management in Adults: A Systematic Review and Meta-Analysis.
Study Goal
The researchers aimed to determine whether participant age, sex, and BMI influenced the effectiveness of brisk walking for obesity management in adults.
Results Summary
Brisk walking led to clinically significant reductions in body weight, BMI, waist circumference, and fat mass for obese men and women under 50. Obese women over 50 achieved modest losses, but gains in fat-free mass reduced overall weight change.
Population
Obese adults (men and women), with specific findings stratified by age (under and over 50) and sex.

BACKGROUND: Brisk walking is the most popular activity for obesity management for adults. We aimed to identify whether participant age, sex and body mass index (BMI) influenced the effectiveness of brisk walking. METHODS: A search of 9 databases was conducted for randomized controlled trials (RCTs). Two investigators selected RCTs reporting on change in body weight, BMI, waist circumference, fat mass, fat-free mass, and body fat percentage following a brisk walking intervention in obese adults. RESULTS: Of the 5072 studies screened, 22 met the eligibility criteria. The pooled mean differences were: weight loss, -2.13 kg; BMI, -0.96 kg/m CONCLUSIONS: Brisk walking can create a clinically significant reduction in body weight, BMI, waist circumference, and fat mass for obese men and women aged under 50 years. Obese women aged over 50 years can achieve modest losses, but gains in fat-free mass reduce overall change in body weight. Further research is required for men aged over 50 years and on the influence of BMI for all ages and sexes.
