What is already known about this subject
- • Recent obesity trends across the world in adults are mixed, varying from showing signs of levelling off to a continuously increasing prevalence.
- • Secular trends in body mass index (BMI) and waist circumference may vary by sex and age.
- • Relying exclusively on BMI data may lead to underestimate the obesity epidemic.
What this study adds
- • Adverse trends in obesity indicators have continued in Finland in the 2000s.
- • In older men, BMI remained quite stable and in older women BMI has decreased since 1997.
- • Steep upward trends in abdominal obesity (waist circumference and waist-to-height ratio, WHtR) have taken place in both men and women and in all age groups, especially during the past 10 years.
- • The impact of BMI adjustment on trends in abdominal obesity varied by age such that increases in BMI-adjusted waist circumference and WHtR were more prominent in older age groups.
