The Growing Concern of Obesity in Nigeria
Obesity is no longer a concern exclusive to Western nations; it has become a significant public health issue in Nigeria, with far-reaching implications for both individuals and society. Experts have raised alarms about the increasing prevalence of obesity, particularly among children and pregnant women. This shift in health challenges reflects a broader transformation in the country’s health landscape, where chronic, non-communicable diseases are now as prevalent as infectious ones.
Over the past three decades, Nigeria has witnessed a dramatic change in health trends. What was once focused on combating infectious diseases has now expanded to include the management of conditions such as obesity, diabetes, hypertension, and various cancers. This phenomenon, known as the “double burden of disease,” highlights the coexistence of both communicable and non-communicable diseases within the population.
The rise in obesity can be attributed to several factors, including rapid urbanization, a decline in physical activity, and the growing consumption of high-calorie, processed foods. These changes have significantly altered the Nigerian diet, making it more reliant on fast food and sugary beverages. As a result, obesity rates have surged, particularly among children.
According to a study published in The Lancet, the prevalence of overweight children aged 5 to 14 years in Africa increased by 67.1% from 1990 to 2021, while obesity rates rose by an alarming 215.8% during the same period. Projections suggest that these figures may continue to grow, with estimates indicating a further increase of 33.3% in overweight children and 140.3% for obesity by 2050.
Dr. Charles Adedamola Adeogun, a physician and public health advocate, emphasizes the serious medical implications of obesity. He notes that obesity is not just a matter of body size but a disease in itself, closely linked to hypertension, type 2 diabetes, heart disease, infertility, arthritis, stroke, and even certain types of cancer. He attributes the rise in childhood obesity to sedentary lifestyles, excessive screen time, and poor dietary patterns.
The World Health Organization (WHO) has also highlighted the global obesity crisis, noting that over 35 million children under age five were estimated to be overweight in 2024. The organization continues to promote its Acceleration Plan to Stop Obesity through comprehensive, life-course, and multi-sectoral policies.
The Implications of Obesity During Pregnancy
Obesity during pregnancy poses significant risks for both mothers and their babies. Dr. Margaret Obienu, a resident physician at Lagos University Teaching Hospital, explains that obesity increases the risk of complications such as miscarriage, gestational diabetes, gestational hypertension, pre-eclampsia, venous thromboembolism, and preterm labor. For the fetus, there is an increased risk of congenital anomalies, fetal macrosomia, and prematurity.
Antenatal care for obese pregnant individuals presents additional challenges, including difficulties in measuring blood pressure, performing obstetric examinations, and conducting ultrasound scans. Labor complications can also arise, with increased risks of slow progress, instrumental delivery, traumatic injuries, perinatal asphyxia, emergency cesarean sections, excessive bleeding, and poor wound healing.
To address weight management prior to conception, Dr. Obienu advises obese women to seek preconception care, which includes lifestyle modifications such as weight loss, exercise, and dietary changes. Folic acid supplementation and stabilizing co-existing medical conditions are also crucial steps in mitigating complications during pregnancy.
Dietary Recommendations for Managing Obesity
A registered dietitian, Toluwalope Phoebe Farodoye, provides key strategies for managing obesity through proper nutrition. She emphasizes the importance of achieving appropriate gestational weight gain, ideally within the recommended range of 5 to 9 kg (11 to 20 lb). A balanced, calorie-controlled diet should focus on fruits, vegetables, whole grains, lean protein sources, and low-fat dairy products.
Farodoye recommends portion control, minimizing the intake of added sugars and saturated fats, and ensuring adequate consumption of essential micronutrients such as folate, iron, and calcium. For women planning to conceive, she advises adopting a nutrient-dense diet and starting daily folic acid supplementation at least one month prior to conception.
In addressing the role of processed and fast foods in contributing to obesity, Farodoye highlights the need to reduce their consumption and promote healthier alternatives. She suggests replacing sugary snacks and beverages with water, unsweetened fruit-infused water, smoothies, or low-fat milk, and substituting pastries and candies with fresh fruits, yogurt, or roasted nuts.
Strategies for Healthy Eating Habits
Farodoye emphasizes the importance of adhering to age-specific dietary guidelines, such as the WHO growth standards and the My Plate model. Parents are encouraged to serve small, frequent, nutrient-dense meals rather than traditional large meals, especially for children whose stomachs are still developing.
Successful meal planning involves preparation, selecting nutritious food items, and preparing balanced meals in advance. Families are encouraged to develop weekly menus featuring a diverse array of fruits, vegetables, whole grains, lean proteins, and healthy fats. Shopping with a list helps minimize impulse purchases of processed foods.
Practices such as batch cooking and portioning meals support consistency and facilitate portion control. Involving the entire family in this process, including setting regular meal times and engaging children in meal preparation, fosters healthier habits and long-term adherence to balanced eating.
For adults struggling with obesity, Farodoye emphasizes that an adequate, calorie-controlled diet combined with regular physical activity remains the cornerstone of effective weight management. While dietary supplements and functional foods may offer supportive benefits, they should not replace a balanced diet.
