title: Congenital malformations in primary health care in Al-Qassim region.
abstract: The objective of this predesigned research was to determine the prevalence, sociodemographic correlates, and pattern of congenital malformations (CMs) in a population less than 20 years of age. From January 1991 to December 1991, the extensive examination of family health files coupled with door-to-door survey identified 1736 patients with CMs. The results showed that the prevalence of CMs was 6.9/1000 population. The male to female ratio was 1.3:1. The patient's age, sibling order, co-morbid disorders of CMs, parental age, chronic maternal diseases, and the family history of CMs were significantly associated with groups of arbitrarily classified CMs. The most frequently encountered CMs were of central nervous system (39.2%) followed by cardiovascular (22.3%), alimentary (13.1%), musculoskeletal (6.85%), urogenital (6.16%), communicative and audiovisual (5.5%), and miscellaneous (6.9%). Further one-way ANOVA found significant differences among CM categories and age of patients and parents. Unlike Western trends, our study tentatively concludes that overall the inheritance rather than socioenvironmental factors contributes significantly in the etiology of different congenital malformations. We further suggest that the basic information of this research might be useful foundation data in future analytic studies on congenital malformations.
