People who were obese by the time they were 25 years of age had a greater risk of developing more severe obesity later in their lives.

While this seems to be a bleak projection for those battling obesity, the study also revealed some more hopeful findings. Examining the effects of long-term obesity, the study showed that present weight, as opposed to the duration of obesity, was a much better indicator of cardiovascular and metabolic risk. This means that losing weight at any stage may help reduce risks, regardless of how long a person has been overweight.
"The current findings suggest that the biological risks of longer-term obesity are primarily due to the risk of more severe obesity later in life among those obese early in life, rather than the impact of long-term obesity per se," explains study lead author Jennifer B. Dowd, PhD, Associate Professor, Epidemiology and Biostatistics, City University of New York (CUNY) School of Public Health, Hunter College. "This is good news in some respects, as overweight and obese young adults who can prevent additional weight gain can expect their biological risk factors to be no worse than those who reach the same level of BMI later in life."
Although the study found that current weight was a better indicator of risk than the length of obesity, it is still significant that those obese at 25 years were more likely to be morbidly obese in middle age. By being more likely to reach severe levels of obesity, they are more susceptible to complications such as hypertension, inflammation, and diabetes. Also, investigators admit that long-term obesity may play a role in other chronic conditions.
"Duration of obesity may still have important implications for mobility and musculoskeletal disease, research questions that should be investigated. Prevention of weight gain at all ages should thus be a clinical and public health priority," adds study co-author Anna Zajacova, PhD, Assistant Professor of Sociology at the University of Wyoming.
As the obesity epidemic continues to unfold, studies like this give us better insight into both the short and long-term effects of being overweight, as well as a model to predict those who are most at risk later in life.
