Study design and methodology

Saudi Maternal and Child Health Survey was designed to study the utilisation of maternal health services by ever-married women of child-bearing age, by measuring level of tetanus vaccination coverage; breastfeeding and meaning knowledge, attitude and practices; and by measuring the level of vaccination coverage with BCG, DPT, Poliomyelitis and measles vaccines among children 1-2 years old at the national level. The standard world health organization (WHO) cluster technique was employed. The kingdom was divided into five geographical areas. The sampling frame used was available at the Ministry of Health (MOH) in the form of ascending cumulative frequency tables where the catchment areas of 1625 health centres (HC) constitute primary sampling units (PSUs). Thirty clusters were randomly selected from each of the five geographic areas, and 40 household per cluster were used. The target populations included: (i) the ever-married Saudi females in the child-bearing age (15-49 years), (ii) children less than 5 years old, and (iii) children 1-2 years old. The respondents were interviewed using a questionnaire. The quality of data was assured by pre-coding of data which was edited throughout the field work period. A 4-day workshop was held for the interviewers and supervisors 48 hours prior to commencement of the survey. During the workshop, interviewers were instructed to read the questions precisely, were acquainted with survey methodology in general, pretested the questionnaire, received guide manual, instruction notes, progress sheets and follow-up formats for referring to when needed. The investigators were in the field during the first few days to solve any problem arising.
