Social Backgrounds for Mothers Having Infants and Children with Developmental Dysplasia of Hip

Abstract

Background: Developmental dysplasia of the hip (DDH) embraces conditions of varying severity. Early identification of affected infants is important for optimal outcome. The incidence of DDH is variable and depends on many factors. Approximately one in 1 000 children is born with a dislocated hip, and 10 in 1 000 may have hip subluxation. Factors contributing to DDH include breech presentation, female sex, positive family history, firstborn status, and oligohydramnios. Intrauterine position, sex, race, and positive family history are the most important risk factors. These factors have been meticulously globally studied by many researchers, this study aimed at exploring the effect of social backgrounds for mothers having babies with DDH. Aim: To examine the impact of different socio-economic and medical characteristics for women and the subsequent occurrence of developmental dysplasia of hip among their children. Study design: Case-control study, where 43 women with DDH babies, were allocated as cases. Another 91 women who have not had babies with DDH were considered as controls. Study period: 1st. February 2007 to 1st. December 2007.Data collection tools: Including, assessment of socio-economic features such as personal characteristics, life events and social context. In addition, previous history of oral contraceptive usage and the presence of one or more of chronic non-communicable diseases were also gained. Results: Regarding Personal Characteristics; positive family history was found to be significantly associated with the development of DDH (P=0.001), while sedentary life styles were found to be significantly negatively associated with the occurrence of DDH (P=0.022). According to Life Events; stress, in this work appeared to be significantly associated with the development of DDH (P= 0.017), while social discontinuities and geographical mobility, both showed negative significant association with DDH. Regarding Social Context, both social disintegration and urbanization appeared to be significantly (P=0.032, P=0.023 respectively), negatively associated with the occurrence of DDH. According to Other Variables, the previous history for use of oral contraceptives showed significant (P=0.018) negative association with DDH, while obesity in women appeared to be positively associated with the occurrence of DDH among their children. Conclusion: Women with positive family history stress and obesity appeared to be at significant risk to have children with DDH. While, women with sedentary life, social discontinuities, geographical mobility, social disintegration, urbanization and previous usage of oral contraceptives appeared significantly protected from having children with DDH.Key words: Social, Backgrounds, Mother, Developmental Dysplasia of Hip
