Dental Caries
- Streptococcus mutans uses CHO as food and excretes acid, causing tooth decay
- Exposure to strong caries promoters (e.g., sticky candy) contributes to dental caries
- Prevention methods:
- Seek early pediatric dental care
- Begin oral hygiene when teeth appear
- Use fluoridated toothpaste
- Avoid using a bottle (milk or juice) at bedtime
- Avoid snacking on sticky CHO throughout the day
- Drink fluoridated water
- Fluorosis (staining of the teeth) can be caused by:
- Excessive fluoride supplementation
- Consumption of toothpaste with fluoride
- Natural water supply high in fluoride
Constipation
- Passage of hard and dry stools associated with painful bowel movement
- Contributing factors:
- Painful experience
- Lack of privacy or cleanliness (preschool)
- Avoidance of toilet due to involvement in play
- Diet (sugar and desserts prone to constipation)
- Switching milk (breast milk vs. formula)
- Intense changes (illness, bedridden, eating less, dehydration)
Nutrition Recommendations
- Adequate intake of fibre: 19-25 g/day for young children (RNI Malaysian, 2017)
- Fluid intake: 4-6 glasses of water per day for children between 2-6 years (Malaysian Dietary Guidelines)

Iron-Deficiency Anaemia
- Toddlers (esp. 9 – 18 months old) are at highest risk due to rapid growth rate and inadequate iron intake
- Caused by decreased production of RBCs
- Other causes: dietary factor (deficiency of folate) and non-dietary factor (chronic inflammation or recent infection)
Diagnosis of Iron-Deficiency Anaemia
- Based on the 5th percentile of Hb & Ht for age
- Hemoglobin concentration and hematocrit levels vary by age:
- 1–2 years: < 11.0 g/dL and < 32.9 %
- 2–5 years: < 11.1 g/dL and < 33.0 %
- 5–8 years: < 11.5 g/dL and < 34.5 %
- 8 – 12 years: < 11.9 g/dL and < 35.4 %
Signs & Symptoms
- Lethargy, pale skin, unable to pay attention, shortness of breath, palpitations or irritability
- Consequences in young children: long-term delays in cognitive development and behavior disturbances
Identification & Prevention
- Children at risk: those who have a low-iron diet or consume more than 24 oz of milk per day
- Prevention: increase intake of meat, poultry, and fish, and offer children healthier choices
Dental Caries
- Prevalence among Asian children:
- 40% to 97% in Eastern Asia
- 38%-73.7% in Southern Asia
- 26.5%-74.7% in Western Asian countries
- Causes: baby-bottle tooth decay, frequent exposure to CHO foods, and poor dietary choices
- Prevention: good oral hygiene, limiting sugary snacks, and regular dental check-ups
Lead Poisoning
- Consequences:
- High level in the blood: affects brain, blood, and kidney
- Elevated blood levels: decreases growth in children
- Low level exposure: associated with decreases in IQ, behavioral problems, and academic achievement
Childhood Obesity
- Increased prevalence rate, affecting both high and low-income populations
- Prevention is the most cost-effective way
- Possible causes: family history of obesity, environmental and social factors, lifestyle factors, and adiposity rebound
- Consequences: type 2 diabetes, hypertension, stroke, PCOS, and depression/low self-esteem
Total Energy Expenditure (TEE)
- TEE is the energy expended by an individual within 24 hours
- Composed of three components:
- Basal metabolic rate (BMR)
- Thermic effect of diet
- Energy expended in physical activity
Basal Metabolic Rate (BMR)
- Accounts for 60-75% of TEE
- Energy required for maintenance of intracellular environment and crucial mechanical processes (e.g., cardiac function and respiration)
- Measurement of BMR requires standardized conditions:
- Postprandial state (12-14 hours after eating)
- Completely relaxed and still (shortly after waking)
- Thermoneutral environment
- Free from thermic effect of drugs
- 20-30 minutes of stable measurements
Resting Metabolic Rate (RMR) and Resting Energy Expenditure (REE)
- RMR: BMR + thermic effect of food (TEF) + state of unrelaxed rest
- REE: measurements made in post-absorptive state
- Values between BMR and RMR/REE differ by approximately 10-15% (RMR > BMR)
Sleeping Metabolic Rate (SMR)
- Energy expended during sleeping
- Accounts for 1-5% of total energy expenditure
