- NORMAL BIRTH WEIGHT
- Infant weighing between 2500g to 4000g irrespective of gestational
age
- LOW BIRTH WEIGHT (LBW)
- Infant weighing less than 2500g irrespective of gestational
age
- VERY LOW BIRTH WEIGHT
(VLBW)
- Infant weighing less than 1500g irrespective of gestational age
- EXTREMELY LOW BIRTH WEIGHT
(ELBW)
- Infant weighing less than 1000g irrespective of
gestational age
- FACTORS
- PRIMARY FACTORS
- PRETERM BIRTH
- Born early (<37 weeks gestation, and often <30 weeks), less
time in the mother’s womb to gain weight. Much of the
weight is gained in the later stages of the pregnancy
- INTRAUTERINE GROWTH RESTRICTION
(IUGR)
- Problems with placenta, maternal health or birth
defects
- MATERNAL FACTORS
- MATERNAL WEIGHT & BMI
- <45kg and underweight
- MATERNAL AGE
- <20yrs and >35yrs
- EDUCATION
- Lack of knowledge on prenatal care, proper diet during
pregnancy and effects of maternal behaviour on fetus
- HISTORY OF LBW
- Mothers with familial vertical history of LBW or
experienced of having LBW infant
- SOSIOECONOMIC CONDITION
- Deprived socioeconomic level such as unhygienic
environment and improper diet
- SMOKING, ALCOHOL & DRUG ABUSE
- Interrupt the baby’s growth in the womb and increase
the risk for premature birth and birth defects
- PREGNANCY RISK
FACTORS
- SUPPLEMENTATIONS
- Percentage of LBW babies is higher in mothers who had
not taken iron-folic acid (IFA) supplements
- MULTIPLE PREGNANCY
- Multiple parity (twin or more) is associated with LBW
- INTER-PREGNANCY INTERVAL
- Interval less than 1 year cause mothers unable to recover from
the biological stresses from the previous pregnancy
- MALNUTRITION
- Proper nutrients are needed for fetus growth, malnourished
mothers increase risk of LBW infants
- MATERNAL INFECTIONS
- Chronic infections such as UTI, STI, malaria or kidney infection during
pregnancy result in direct intrauterine growth leading to LBW
- CONSEQUENCES
- SHORT TERM
- LBW
- VLBW & ELBW
- LONG TERM
- ELBW
- VLBW
- LBW
- = Complications are markedly increased in VLBW, and especially ELBW,
infants.
- The lower a baby's birthweight, the greater are
the risks for complications
