The Cambodia Anthropometrics Survey (CAS) 2008 was conducted to collect updated information on nutrition since the Demographic and Health Survey in 2005, covering micronutrient deficiency, food consumption, disease, coping strategies, breastfeeding, and several targeted health services.

The survey collected anthropometric measurements from 7,495 households with children ages 0-59 months from all areas of the country.

The questionnaire consisted of three sections: for households, children, and mothers or caretakers. The topics from the questionnaires included sociodemographic information, infant and young child feeding, children's diet, child morbidity, and health interventions such as the administration of antihelminthics and the supplementation of iron and Vitamin A.
