A systematic review and meta-analysis were conducted to assess whether childhood obesity predicts adult obesity. The study included 15 prospective cohort studies, with a total of 200,777 participants. The results showed that children and adolescents who were obese were around five times more likely to be obese in adulthood than those who were not. Approximately 55% of obese children became obese in adolescence, 80% remained obese in adulthood, and 70% were obese by age 30. However, 70% of obese adults were not obese in childhood or adolescence, indicating that childhood obesity is not the sole determinant of adult obesity. The study found that BMI was the only measure of obesity used in the included studies, and it was the most commonly used measure. The analysis showed that childhood obesity is a strong predictor of adult obesity, but the predictive accuracy varied across studies. The study also found that obesity is moderately persistent into adulthood, with about 79% of obese adolescents still obese as adults. However, the predictive accuracy of childhood BMI for adult obesity was limited, as many obese adults were not obese in childhood or adolescence. The study concluded that while childhood obesity is a significant predictor of adult obesity, it is not the only factor, and public health interventions should consider the broader context of obesity development. The study also highlighted the limitations of using BMI as a measure of obesity and the need for further research on alternative measures. The review was conducted following established guidelines for systematic reviews and meta-analyses, and the results were synthesized using statistical methods to estimate summary sensitivity and specificity. The study found that childhood obesity is a major public health issue, and early intervention may be necessary to reduce the burden of adult obesity. However, the study also emphasized the importance of considering the broader context of obesity development and the limitations of using BMI as a measure of obesity. The study was funded by the National Institute for Health Research and was part of a broader health technology assessment. The study was conducted in accordance with ethical guidelines, and the results were interpreted by the authors. The study was published in the Obesity Reviews journal and is available online.
