New growth charts for Libyan preschool children

ABSTRACT

To draw up new growth charts for Libyan children under 5 years of age, a cross-sectional survey was carried out in urban and rural areas in 2 regions of the Libyan Arab Jamahiriya from June 1999 to February 2000. Using WHO cluster sampling methodology, 1473 infants and children of both sexes aged between 0 and 59 months were selected from residential areas, maternal and child health centres, kindergartens and the delivery section of hospitals. Growth charts for weight-for-age, height for-age and weight-for-height were plotted and smoothed, to provide reference curves for clinical, epidemiological and research purposes. In addition, mean Z-scores were analysed by sociodemographic variables collected from interviews with parents. Factors with a strong influence on childhood growth patterns were child's age, mother's education level and sex
