    WMG (World Masters Games) athletes have either pursued a physically active lifestyle for an extended period of time or have initiated exercise/sport in later life. This unique cohort of middle-aged to older-aged adults remains relatively uninvestigated with regards to various measures of health. With a need for multifaceted solutions to the obesity epidemic, investigating specialpopulations such as those competing in sport at older ages may further the understanding of the nexus between aging, physical activity and obesity. This study aims to investigate the BMI (body mass index) of North American WMG competitors with respect to national health guidelines and demographics. An online survey was utilized to collect demographic information from athletescompeting at the Sydney WMG. BMI was derived using the participant’s height and body mass. A total of 928 (46.7% male, 53.3% female) participants from Canada and the United States (age: 52.6 ±9.8 years) completed the survey. The top 5 sports in which participants competed were football (25.6%), track/field (15.4%), swimming (8.4%), volleyball (8.2%), and softball (7.8%). Femaleand male BMI (kg/m2) across all sports were: > 30 (obese: 13.9%), 25-29.9 (overweight: 34.1%), 18.5-24.9 (normal: 50.3%), and <18.5 (underweight: 1.7%). Data indicated that BMI was a health risk factor for 13.9% of the participants and a developing risk factor for 34.1% of the participants. Analysis demonstrated a significantly reduced (P < 0.05) classification of obesity of the North American WMG competitors when compared to Canadian and United States national populations. It is believed that adherence to exercise improves indices of general health. A key index of health (obesity) is significantly lower in incidence for North American WMG competitors when compared to Canadian and US populations.
