title: Nutritional status of 11-12-year-old Jamaican children: coexistence of under- and overnutrition in early adolescence.
abstract: OBJECTIVE
  To determine the nutritional status of a cohort of 11-12 year olds and ascertain social and demographic factors associated with under- and overweight in early adolescence.
  
  
  METHODS
  Cross-sectional.
  
  
  METHODS
  Subgroup (n = 1698) of the birth cohort (September-October 1986) of the Jamaican Perinatal Survey enrolled in schools in the Kingston Metropolitan area. One thousand and sixty-three parents or caregivers provided social and demographic information.
  
  
  RESULTS
  Undernutrition and overnutrition are of public health significance among adolescent Jamaican children. Ten per cent of 11-12 year olds had body mass index (BMI) values below the 5th percentile (boys, 10.6%; girls, 7.1%) but this prevalence is relatively low compared with other developing countries. The prevalence of stunting was low (3%). The prevalence of overweight (BMI > or = 85th percentile) (19.3%) was approaching prevalence rates found in the USA. Similar social and demographic variables were associated with thinness and fatness in males. Birth weight predicted overweight in girls.
  
  
  CONCLUSIONS
  Under- and overnutrition in early adolescence are important problems in Jamaica. There is a need to address both under- and overnutrition in adolescence in preventive and rehabilitative intervention programmes.
