Changes in Body Weight and Concurrent Changes in Cardiovascular Risk Profiles in Community Residents in Japan: the...

Area of Science:

• Cardiovascular disease research
• Obesity studies
• Public health interventions

Background:

• Weight change significantly impacts cardiovascular disease (CVD) risk.
• Understanding weight trajectories is key to managing CVD risk factors.
• Community-based studies provide real-world insights into health behaviors.

Purpose of the Study:

• To investigate how weight change influences predicted cardiovascular disease (CVD) risk.
• To examine concurrent changes in individual CVD risk factors over time.
• To assess the impact of different weight trajectories on health outcomes.

Main Methods:

• Analysis of 2,140 community-dwellers aged 40-74 years with data from 2002 and 2007.
• Classification of weight trajectories: stable obese, obese to nonobese, nonobese to obese, stable nonobese.
• Comparison of model-predicted CVD risk and individual risk factors across weight-change categories.

Main Results:

• Predicted CVD risk increased over 5 years in all groups.
• The "obese to nonobese" group showed the smallest increase in CVD risk.
• Weight loss in obese individuals and weight maintenance in nonobese individuals led to favorable changes in CVD risk factors.

Conclusions:

• Losing weight is favorably associated with reduced future CVD risk in obese individuals.
• Avoiding excessive weight gain is important for nonobese individuals to mitigate CVD risk.
• Findings support enhancing lifestyle interventions with weight change health consequences information.
