-Factors affecting human linear growth.

Factors affecting human linear growth.

• Age
• Sex
• Race.
• Hereditary factors:- Children of two short parents will probably be short and vice versa.
• Endocrinal factors e.g Growth Hormone which is responsible for stimulation of body growth in humans.
• Nutritional factors:- Adequate nutrients must be available for normal growth.
• General health:- Any serious systemic disease in childhood is likely to reduce growth (e.g. chronic kidney disease or chronic infection).
• Intrauterine growth retardation (small birth weight):-These infants often growpoorly in the long term.
• Emotional deprivation and psychological factors:- These can impair growth by complex, poorly understood mechanisms.
• Chromosomal abnormalities.
• Skeletal maturity.
