Body mass index and waist circumference trajectories across the life course and birth cohorts, 1996–2015 Malaysia: sex and ethnicity matter
An erratum to this article was published (Int J Obes (Lond), Mar 2024 ↗)
Authors' conclusion
The profound increasing cohort trajectories of obesity, regardless of sex and ethnicity, are alarming. Future studies should focus on identifying factors associated with the less profound cohort effect among the Chinese to reduce the magnitude of trajectories in obesity, particularly among future generations.
Study context
- Population
- Non-institutionalized Malaysian adults aged 18 to 80 years
- Exposure
- BMI and waist circumference trajectories by sex and ethnicity
- Outcome
- BMI and waist circumference trajectories across the life course and birth cohorts
Methodological detailspooled data from four population-based National Health and Morbidity Surveys (1996, 2006, 2010, 2015), Hierarchical Age-Period-Cohort (HAPC) models assuming no period effect

Main finding
As reported in the abstract
BMI and waist circumference trajectories
- BMI and waist circumference trajectories generally increased across age and birth cohorts, varying by sex and ethnicity
- Females had more profound increasing BMI and waist circumference trajectories than males with age and cohort recency
- Chinese had less profound BMI and waist circumference increases across the life course and birth cohorts than other ethnic groups
Observational data: associations, not effects.
