Childhood obesity is one of the most serious public health challenges of the 21st century. The WHO reports that the number of overweight or obese children and adolescents has risen dramatically over the past four decades. In the UAE, an estimated 13-15% of children are classified as obese, with higher rates of overweight.
Why Does Childhood Obesity Matter?
Immediate Health Effects
- Type 2 diabetes (once considered an adult disease, now increasingly seen in children)
- High blood pressure
- High cholesterol
- Asthma (obesity worsens symptoms)
- Sleep apnoea
- Joint problems and musculoskeletal pain
- Fatty liver disease
Long-Term Health Consequences
- Obese children are significantly more likely to become obese adults
- Increased lifetime risk of cardiovascular disease, type 2 diabetes, and certain cancers
- Reduced life expectancy
Psychological Impact
- Low self-esteem
- Bullying and social isolation
- Depression and anxiety
- Poor body image
Contributing Factors
Childhood obesity results from multiple interacting factors:
Dietary Factors
- Excessive intake of high-calorie, nutrient-poor foods (fast food, sugary snacks, sweetened beverages)
- Large portion sizes
- Irregular meal patterns (skipping breakfast, frequent snacking)
- Low intake of fruits, vegetables, and whole grains
Physical Activity
- Sedentary lifestyles (excessive screen time, insufficient outdoor play)
- WHO recommends children aged 5-17 get at least 60 minutes of moderate-to-vigorous activity daily - many do not achieve this
- Hot climate in the UAE can limit outdoor activity during summer months
Screen Time
- The average child spends several hours per day on screens (TV, tablets, phones, gaming)
- Screen time is associated with reduced physical activity, mindless snacking, and disrupted sleep
Sleep
- Insufficient sleep is independently associated with weight gain in children
- Recommended sleep: 9-12 hours for ages 6-12; 8-10 hours for teenagers
Genetics and Family Environment
- Children with obese parents are more likely to be obese (genetics plus shared environment)
- Family eating habits and activity levels strongly influence children
Management: A Family Approach
NICE guideline NG246 and the AAP emphasise that weight management in children should be:
- Family-centred (involving the whole family, not singling out the child)
- Gradual (in growing children, the goal is often weight maintenance or slowed gain, allowing height to "catch up")
- Positive (focused on health and wellbeing, not appearance or restriction)
Dietary Changes for the Family
- Cook and eat meals together at home as often as possible
- Include vegetables and salad with every main meal
- Replace sugary drinks with water, milk, or diluted juice
- Keep healthy snacks accessible (fruit, vegetables, nuts, yoghurt)
- Remove or limit access to sweets, crisps, and biscuits
- Avoid using food as a reward or punishment
- Teach children to recognise hunger and fullness cues
- Model healthy eating - children learn from their parents
Increasing Physical Activity
- Make activity fun - swimming, cycling, football, dancing, playground time
- Walk to school when possible
- Limit screen time to 1-2 hours per day for entertainment
- Be active as a family (walks, bike rides, park visits)
- In the UAE, use indoor facilities during summer (malls with play areas, indoor sports centres, swimming pools)
Sleep and Screen Habits
- Establish a consistent bedtime routine
- Remove screens from bedrooms
- No screens for at least 1 hour before bed
- Ensure adequate sleep duration for age
Psychological Support
- Avoid negative language about weight or body shape
- Praise efforts and healthy choices, not appearance
- Address bullying if it occurs
- Seek professional support if the child shows signs of low mood or disordered eating
When to Seek Medical Help
Consult your paediatrician if:
- Your child's BMI is consistently above the 91st percentile (overweight) or 98th percentile (obese) on growth charts
- Weight gain is rapid or unexplained
- You are concerned about your child's relationship with food
- There are symptoms of complications (excessive thirst, joint pain, snoring, skin darkening at the neck or armpits)
