In Ghana, obesity is rising rapidly due to urbanisation, changing diets, and reduced physical activity, marking a shift from infectious diseases to lifestyle-related conditions and increasingly affecting both adults and younger populations.
Rising Prevalence
Over the past two decades, Ghana has recorded a steady increase in overweight and obesity. Current estimates indicate that about 17% of adults are obese, while over 40–43% are either overweight or obese, meaning roughly 2 in every 5 adults fall above a healthy weight range. Among women, particularly those of reproductive age, the burden is significantly higher, with 45–50% classified as overweight or obese, compared to 20–30% among men, highlighting a clear gender disparity (Ghana Demographic and Health Survey; BMC Public Health; Journal of Health, Population and Nutrition).
Childhood and adolescent obesity is also rising, with urban-based studies suggesting 8–15% prevalence among school-aged children, signaling a growing long-term public health concern.
Unequal Burden
- Obesity in Ghana is unevenly distributed, with clear demographic and geographic differences:
- Women are up to 2 times more likely to be obese than men
- Urban residents have prevalence rates nearly 1.5 to 2 times higher than rural populations
- Higher-income households show significantly higher obesity rates, often linked to diet and lifestyle
In major cities such as Accra, sedentary lifestyles and dietary shifts have intensified the problem (World Health Organization; University of Ghana research).
Key Drivers
The rise in obesity is closely tied to Ghana’s ongoing nutrition transition, marked by measurable behavioural shifts. These changes reflect broader economic and social transformations.:
- Increased intake of energy-dense foods, with some studies estimating over 30% of daily calories coming from processed foods in urban settings
- Physical inactivity levels affecting approximately 25–30% of adults, particularly in formal employment sectors
- Rapid urbanisation, with more than 55% of the population now living in urban areas, influencing both diet and activity patterns
Health Implications
Obesity is a major driver of non-communicable diseases (NCDs) in Ghana. It is estimated that:
- Over 48% of adults have hypertension, many of whom are overweight or obese
- About 6–7% of adults live with diabetes, with a large proportion linked to excess weight
- Individuals who are obese are 2 to 3 times more likely to develop cardiovascular diseases
- This growing burden is increasing pressure on the health system, which continues to manage both infectious diseases and rising chronic conditions.
Overall Outlook
Obesity in Ghana reflects a dual burden of disease, where undernutrition and overnutrition coexist. While awareness and policy responses are improving, the scale of the problem affecting millions of adults and a growing number of children points to the need for sustained, system-wide interventions across health education, food systems, and urban planning.
