Heavy Lifting: How Excess Weight Affects Construction Workers’ Performance

Introduction

The UK construction industry is a cornerstone of the nation’s economy, employing hundreds of thousands of workers. The demographic characteristics of the construction worker population show a diverse workforce, with notable variations in age that can influence health behaviors and risks. However, recent studies reveal a concerning trend: a significant proportion of construction workers are overweight or obese. In a 2025 cross-sectional study based on a sample of construction workers, 32.6% of UK construction workers were classified as overweight, with 51.7% exhibiting elevated blood pressure and 30.2% falling under Stage 1 hypertension. These figures align with broader international findings, where up to 73.3% of construction workers in some studies were overweight or obese, based on a comparison with the general population. This prevalence is notably higher than in many other occupational sectors, highlighting differences between this group and other groups.

The Impact of Excess Weight on Construction Performance

Physical Demands and Musculoskeletal Strain

Construction work is physically demanding, requiring strength, endurance, and flexibility. Excess body weight increases the strain on the musculoskeletal system, making tasks such as lifting, carrying, and climbing more challenging. Overweight workers are at higher risk for musculoskeletal disorders, particularly in the neck, shoulders, lower back, legs, and knees. Nearly half of construction workers report experiencing body pain in the past three months, with pain most commonly affecting areas critical for manual labour.

Productivity, Absenteeism, and Safety

Excess weight is correlated with increased absenteeism and reduced productivity. Workers with higher body weight are more likely to be absent due to health issues, leading to lower overall wages and greater indirect costs for employers. Obesity also raises the risk of occupational diseases, including cardiovascular disease, asthma, and vibration-induced injuries. Additionally, excess weight can limit the effectiveness of personal protective equipment and increase the likelihood of workplace accidents, particularly when operating heavy machinery or working at heights. Many construction workers also drive long distances by car to reach job sites, which increases their exposure to transportation-related risks such as motor vehicle accidents.

Mental Health and Wellbeing

Beyond physical health, overweight construction workers are more likely to experience mental health challenges. In the UK, 74.3% of construction workers were found to have medium mental wellbeing, and over half showed signs of minimal depression. Stress, depression, and anxiety are significant predictors of sickness absence and presenteeism, further impacting workplace performance. Some workers may turn to drink as a way to cope with these mental health challenges, which can further impact their wellbeing.

Understanding the Causes of Excess Weight in Construction Workers

The high prevalence of overweight construction workers is shaped by a unique set of factors tied to the nature of their work and lifestyle. While construction workers engage in physically demanding manual labor, this activity does not always equate to the kind of structured physical activity that supports healthy weight management. The unpredictable schedules and long hours common in the construction industry often lead workers to choose quick, convenient meals that are typically high in calories, fat, and sugar.

Additionally, access to healthy food options on or near construction sites is often limited, making it difficult for workers to maintain a balanced diet. The culture within the construction industry can also play a role, as social norms may prioritize productivity and endurance over health, leading to habits such as skipping meals or relying on energy-dense snacks. Alcohol consumption is another factor, with many workers turning to drinks after a long day, which can further increase calorie intake and contribute to weight gain. These combined lifestyle and environmental factors not only increase the risk of overweight and obesity but also heighten the likelihood of related health issues, ultimately impacting productivity and overall wellbeing.

Barriers to Weight Management in the Construction Industry

Despite the clear health risks associated with excess weight, construction workers face several barriers to effective weight management. One of the most significant challenges is the lack of access to healthy food options on construction sites, where vending machines and fast food are often the most convenient choices. The physically demanding nature of construction work can also lead to fatigue and injuries, making it difficult for workers to engage in additional physical activity or structured training outside of work hours.

Long shifts and irregular schedules leave little time for meal planning, exercise, or participation in wellness programmes. The culture within the construction industry may discourage open discussions about health and weight management, with some workers feeling pressure to prioritize work over personal wellbeing. Additionally, the cost of healthy foods and gym memberships can be prohibitive, especially for those on tight budgets. These barriers make it challenging for construction workers to adopt and maintain healthy lifestyle habits, underscoring the need for targeted support and accessible resources within the industry.

The Role of Diet and Exercise in Managing Weight

For construction workers, a balanced approach to weight management is essential for maintaining health and productivity. Prioritizing a nutritious diet that includes plenty of fruits, vegetables, whole grains, and lean proteins can help workers manage their weight and reduce health risks. Limiting the intake of processed foods, sugary snacks, and high-calorie drinks is equally important, especially given the limited healthy options often available on construction sites.

Regular physical activity is another key component of effective weight management. While construction work is physically demanding, incorporating additional exercise—such as cardiovascular workouts, strength training, and flexibility exercises—can further support overall health. Simple changes, like taking the stairs, walking during breaks, or participating in on-site fitness activities, can make a significant difference. Employers can also contribute by providing access to healthy food choices, organizing fitness classes, or offering on-site facilities to encourage a healthier lifestyle. By focusing on both diet and exercise, construction workers can take proactive steps to manage their weight, improve their wellbeing, and reduce the risk of long-term health issues.

Why Addressing Excess Weight Matters

The high prevalence of overweight and obesity among construction workers is not just a personal health issue-it’s a sector-wide concern. Excess body weight contributes to:

• Increased risk of chronic diseases (e.g., diabetes, hypertension, cardiovascular disease)
• Higher rates of musculoskeletal injuries and pain
• More frequent and longer absences from work
• Reduced productivity and efficiency
• Greater risk of workplace accidents and safety incidents

The majority of construction workers are affected by at least one of these health or productivity issues.

These factors combine to create a substantial economic burden for both workers and employers, making effective weight management strategies a priority for the industry.

New Solutions: Medical Weight Loss Programmes

To achieve lasting results, it is important to continue making healthy lifestyle changes alongside medical interventions.

The Rise of Semaglutide and Ozempic

In the UK, there has been a surge in interest around new weight loss medications, particularly those containing semaglutide, such as Ozempic and Wegovy. While Ozempic is primarily licensed for type 2 diabetes, its active ingredient, semaglutide, is also used in Wegovy, which is approved for weight management.Awareness of these medications is high: 42.4% of UK respondents know about semaglutide, and 44.8% have used it for weight loss. These medications work by suppressing appetite and regulating blood sugar, helping users achieve significant weight loss when combined with healthy lifestyle changes.
