Childhood obesity is on the rise, mostly in the low-income regions in South Asia including Sri Lanka. Simultaneously, undernutrition also continues to be an ongoing public health issue. The coexistence of childhood obesity with undernutrition has resulted in a double burden of malnutrition in these countries.
Management of obesity in a community already affected by undernutrition is a challenging situation. At present, management of childhood obesity occurs as a hospital-based lifestyle modification intervention which cannot address all tiers in the community alike. Although national level multifaceted strategies are in place, implementation is limited due to financial constraints. In this context, the general practitioners can be considered as an important group of medical professionals who can reach families in the community.
In many households in Sri Lanka, an overweight child is considered as normal and well-nourished in comparison to an underweight child. Unhealthy eating habits and force feeding have become norms in the society. Changing mindsets of people need significant time and commitment. General practitioners, in the community would be able to achieve this target through effective communication based on a nutrition sensitive approach.
While uplifting the infrastructure facilities, steps have to be taken to update the knowledge and communication skills of the general practitioners on managing childhood obesity in a community affected with double burden of malnutrition. The well-equipped GP is an asset to modify the attitudes and thinking patterns of parents with regard to child nutritional problems.

The rising prevalence of obesity in children and adults is a global health concern. Obesity has been determined as a key factor in the aetiology of several non-communicable diseases (NCD) including cardiovascular disease, type 2 diabetes, non-alcoholic steatohepatitis and several types of cancer
During the past four decades, the worldwide prevalence of childhood obesity has plummeted by nearly eight-folds among children and adolescents and it is anticipated to escalate further throughout the world. While the increasing trend in body mass index (BMI) have plateaued in most of the high-income countries, obesity prevalence continues to escalate in the low and low-middle income countries particularly in East and South Asia
The world-wide prevalence of childhood obesity in 2016 was 7.8% in boys and 5.6% in girls
While addressing obesity has been given priority on a global scale, many countries in South Asia are still grappling with high rates of stunting, wasting, and micronutrient deficiencies among children. More than half of the under 5 child population with undernutrition in the world live in South and South East Asia. Consequences of undernutrition are both short-term and long-term. Despite recent progress, undernutrition remains yet a pressing concern in many low-income regions of South Asian countries.
The study conducted by Naotunna et al in a rural region of Sri Lanka in 2017, revealed a survey design adjusted prevalence of underweight and stunting at, 25.93% (95% CI 24.07– 27.89%) and 43.92%(95% CI 40.55–47.56%) respectively
The increasing prevalence of overweight and obesity with simultaneous existence of undernutrition (thinness and stunting) represents an additional health burden for Asian countries, particularly in their low income and nutrition deficit regions
The double burden of malnutrition refers to the coexistence of undernutrition (e.g., stunting, wasting) and overnutrition (e.g., obesity) in the same population, household, or individual. This complex public health challenge can lead to a major health and economic burden to a country.
Hossain et al reported, based on their analysis of Demographic and Health Surveys conducted in Bangladesh, India, Pakistan, Maldives and Nepal, which were conducted between 2009 and 2016, that the prevalence of underweight was 37% in Bangladesh, 19% in Maldives, 38% in India, 29% in Nepal and 28% in Pakistan. Nepal, Bangladesh and India had similar overweight prevalence (between 2% and 4%) while Pakistan (7%) and Maldives (9%) had higher prevalence
A recent Sri Lankan survey reported that the percentages of thinness and overweight (including obese) among children were 19.3% and 13.4%, respectively, while the percentages of thinness and overweight (including obesity) in mothers were 5.0% and 36.5%, respectively
This phenomenon is often observed in low- and middle-income countries experiencing rapid urbanization and undergoing nutrition transitions. Causes of the double burden of malnutrition are multifaceted. Rapid urbanization accompanied by associated lifestyle changes is one of the primary causes. Excessive consumption of ultra-processed food, lack of access to nutritious foods, limited awareness about the importance of balanced nutrition, particularly among the disadvantaged populations are strong contributory factors for the nutrition transition.
The inadequacy of healthcare infrastructure to effectively address both undernutrition and obesity within a population marked by socioeconomic disparities and inequalities remain an unresolved issue in many South Asian countries, including Sri Lanka.
The Sri Lankan government has already embarked on a multidimensional strategic approach towards eliminating the double-burden of malnutrition involving both the curative and the preventive health care sectors
General practitioners are an important group of medical professionals to reach families in the community. However, the general practitioner may find it a challenging task to manage a child with obesity in a community where undernutrition coexists, particularly when it occurs within the same family. In many households in Sri Lanka, parents consider that an overweight child is quite normal, well-nourished and healthy when compared to the underweight child. It is a difficult task to convince the parents and care givers that being overweight is not normal and that excess body fat is unhealthy.
An adolescent with obesity would pose a different type of a challenge to the general practitioner. Adolescents make up to about 18% of the world population and more than half of them live in Asia
Since adolescents are typically considered a “healthy” group, less attention has been paid to adolescent health. The adolescent health programmes in South Asian regions traditionally focus on reproductive and sexual health issues rather than the maintenance of a healthy BMI. Hence, adolescent obesity is often neglected, and not well addressed.
At instances where the same family has kids at both ends of the spectrum of malnutrition, parents may be overwhelmed with different health advice given to treat their children.
Even if the caregivers are convinced about the adverse consequences of high BMI during childhood and beyond, implementation of lifestyle modifications would also be a challenge to the general practitioner.
At present, the management of childhood overweight and obesity is a clinic-based lifestyle modification intervention that include dietary, physical activity and behavioural modifications. Family involvement in the management of an obese child is essential to achieve successful weight reduction. The most important modification in the dietary management is directing the child towards a healthy eating pattern. Severe calorie restriction is not recommended in the paediatric population. The basic concept is a nutritionally balanced diet. The best diet for a child is home-cooked food. It would be a challenge for the parents when they also have an undernourished child in the same household for whom they need to prepare meals with higher energy density while making a low-fat, low-carb meal for the obese child. As a result, chances are extremely high for poor adherence and drop-off from the prescribed lifestyle modification interventions. Most studies published to date on clinic -based weight reduction programmes have demonstrated either a low level effectiveness or only short-term positive effect
In this context, the general practitioner can play a pivotal role in the community setting. Generating awareness through appropriate health education and empowering caregivers of children need to be considered with high priority. Each and every visit to the GP could make a difference in the family’s attitude and approach to caring for their children with nutritional concerns. In this regard, addressing the development of healthy eating habits in the child starting from early infancy is essential. The general practitioner can play a key role in inculcating a better parenting style where responsive feeding is established very early in life followed by introduction of complementary feeding using healthy food choices. By 8-9 months, parents have to start dining with their children as a family, so that role modelling takes place during the meal times. It would allow infants watch their parents and other family members trying new food and the ways of communicating hunger and satiety. Force-feeding
which is a very common practice in Sri Lanka, though not in record, has to be completely discouraged. Most importantly, parents should not feed children to satisfy their own emotional needs but to fulfill the child’s own requirement.
In dealing with older children and adolescents, the communication skill of the medical practitioner will be a decisive factor in achieving success of a lifestyle modification intervention. Adequate health education, delivered appropriate to the child’s age is crucial prior to introduction of the lifestyle changes. Molding an adolescent’s mindset to view body composition maintenance as a proactive behaviour that contributes to the development of their personality and personal wellness would be a successful approach.
General practitioners, in addition to dealing with individual families coming to their practice, can extend their influence on a wider community of the general public through media channels. This collaborative effort ensures a more comprehensive and effective approach to managing the double burden of malnutrition in general practice.
Children and adolescents with obesity could be filtered at general practise to be referred to the specialist paediatric clinics through identifying associated comorbidities such as metabolic abnormalities, obstructive sleep apnoea and psychological concerns.
Addressing the double burden of malnutrition at the general practice level requires a comprehensive and multifaceted approach. It is mandatory to improve the facilities to promote health education, raising awareness about balanced nutrition, healthy eating habits, and the importance of physical activity. While uplifting the infrastructure facilities, steps have to be taken to update the knowledge and communication skills of the general practitioners on managing childhood obesity in a community affected with double burden of malnutrition. This could be achieved through well-planned training programmes and workshops at national level. The well-equipped GP is an asset to modify the attitudes and thinking patterns of parents with regard to child nutritional problems.
As part of multi-dimensional approach to curb childhood obesity, improving accessibility and affordability to nutritious food especially to vulnerable populations would be of paramount importance. At the same time, the healthcare infrastructure has to be strengthened with the facilities to diagnose and manage both undernutrition and obesity.
Implementation of community-based interventions with the involvement of general practitioners, in the form of community programmes targeting both undernourished and obese individuals would be effective.
National level implementation of policies through governmental leadership to reform obesogenic environments, attitudes towards healthy eating and physical activity of children would pave the way towards permanent societal changes
Addressing the double burden of malnutrition in South Asia is a complex challenge, but with a concerted effort from governments, healthcare providers, communities, and international organizations, it would be possible to make progress in managing childhood obesity and undernutrition simultaneously. General practitioners have a pivotal role to play to support affected families with an individualised nutrition-sensitive approach.
Continued research and data collection to monitor and assess the trajectories of both conditions will be mandatory to design evidence-based interventions to address these complex clinical dilemmas and associated social determinants of health.
