Obesity before the age of 30 significantly raises the risk of early death, with studies indicating over a 75% increase in risk. This comes from a large-scale investigation.
Currently, about two-thirds of adults in the UK are considered overweight or obese. Average weights have risen; for instance, the typical man now weighs over 85 kg (around 13st 5lb) while the average woman is about 73 kg (11st), which is over 6 kg heavier than in 1993.
While being overweight is common, research from Sweden points out that gaining weight early in adulthood poses a higher risk of mortality compared to those who gain weight later.
At Lund University in Malmö, researchers monitored 620,000 adults aged 17 to 60. They found that obese women under 30 had an 84% higher chance of dying early, while for men, it was a 79% greater risk when compared to their peers who maintained a healthy weight.
Participants generally added about 0.5 kg per year until they reached 60. However, for those under 30, each half-kilogram increase translated to a 24% greater risk for men and 22% for women.
This study was presented at the European Obesity Congress in Malaga and tracked male participants over an average of 23 years and women for about 12 years.
The researchers emphasized that weight gained before age 30 particularly raised the risk of early death from conditions like heart disease and type 2 diabetes. For women, obesity also heightened the cancer-related mortality risk.
Lead researcher Huyen Le highlighted the critical need to avoid weight gain during late adolescence and early adulthood. She stated, “Gaining weight early and developing obesity is associated with increased risk of dying from several chronic diseases later in life.”
Although weight gain after turning 30 also correlated with early death, the increase in risk was less severe—52% for those aged 30 to 45 and just above 25% for individuals aged 45 to 60.
Professor Tanja Stock, a senior researcher, explained that prolonged exposure to weight gain likely contributes to these health issues, advocating for more initiatives to promote healthy eating and exercise among young adults.
She noted, “Supporting healthy habits during these formative years can yield long-lasting benefits. Even minor weight gain in your 20s can markedly increase the risk of early death if it continues over several years.”
In response to these findings, Sonia Pombo, a director of the study, mentioned the significance of behavior and environment in shaping dietary habits. She emphasized the necessity of urgent action to change food reformulation, restrict marketing practices targeting children, and ensure that healthy options are the most accessible and affordable.
Catherine Jenner, from the Obesity Health Alliance, called the findings a wake-up call. Excess weight in youth increases risks beyond obesity itself—it can lead to type 2 diabetes, heart disease, certain cancers, and deteriorating mental health.
She added that many young individuals are influenced by a food environment dominated by fast food, oversized portions, and highly processed items, which can lead to obesity by their 30s.
This situation reflects longstanding shortcomings in the food industry and a lack of government action to address it. She underscored the importance of preventing obesity if the government wants to ensure longer, healthier lives for individuals.
Such prevention measures must go beyond treatment; decisive actions are essential to make healthy foods both appealing and economical.
