Safe swaddling and healthy hips: don't toss the baby out with the bathwater

Evaluation of the Community's Awareness of Developmental Dysplasia of the Hip: A Cross-Sectional Study in Jordan

BACKGROUND

Developmental dysplasia of the hip (DDH) is a condition where there is an abnormal relationship between the femoral head and acetabulum. DDH is prevalent in Jordan, where late presentations of complicated cases are common due to the absence of a national screening program and cultural behaviors that can exacerbate DDH progression. The study aims to prove that the absence of a nationwide screening program and low awareness of the population about DDH are the primary reasons for the high incidence of late-presenting DDH in Jordan. The study highlights the need for addressing modifiable risk factors like swaddling and correcting common misconceptions such as using multiple diapers as a treatment option.

METHODS

The cross-sectional study evaluated the awareness level of DDH among Jordan residents above the age of 18. An online questionnaire was used, containing two sections. The Chi-square test was used to analyze the level of awareness scores according to demographic variables and cultural norms such as tight swaddling and using multiple diapers. The sample was categorized into three groups based on their scores: low awareness (0-4), moderate awareness (5-8), and high awareness (9-12).

RESULTS

The study included 1013 participants. The results indicated that 48.9% had moderate awareness, 37.8% had low awareness, and 13.3% had high awareness of DDH. Gender and place of residence had no significant relationship with the level of awareness. However, the majority of participants with high and moderate levels of awareness were in the 25-40 years age group, and healthcare workers had the highest levels of awareness. The study showed that 33.9% of participants gained their knowledge from either relatives or self-experience, while awareness campaigns were the least assessed source of information with only 2.9% of participants getting their information from them. The study also revealed misconceptions regarding DDH, such as the belief that tight swaddling and wearing many diapers reduced the risk of developing DDH. Additionally, about half of the participants were unaware of the presence of screening guidelines for DDH.

CONCLUSION

The study underscores the urgent need to establish a national screening program and awareness campaigns to increase knowledge about DDH and prevent late presentations of complicated cases in Jordan. The study findings provide essential information for the development of future DDH campaigns and screening protocols.

Developmental Dysplasia of Hip and Post-natal Positioning: Role of Swaddling and Baby-Wearing

INTRODUCTION

Traditional swaddling, which implies restrictive immobilisation of the infant's lower limbs with the hips in forced extension and adduction, has been shown to be a risk factor for Developmental Dysplasia of Hip (DDH).

METHODS

We reviewed the literature regarding the correlation between DDH and post-natal positioning by swaddling and baby-wearing, to draw awareness of healthcare professionals towards an important risk factor for DDH that has often been overlooked.

RESULTS

There is overwhelming evidence in the literature, by both experimental and clinical studies, that proves the close association between improper post-natal positioning of the baby's hips in extension-adduction and an increased incidence of DDH. On the other hand, "hip safe" swaddling which allows unrestricted flexion-abduction movements of the infants' hips, and the use of baby-wearing devices which keep the lower limbs in an attitude of hip flexion-abduction and knee flexion, is optimal for hip development. Populations which practice these "hip-safe" techniques of infant immobilisation have a lower incidence of DDH as compared to those which practice restrictive immobilisation. Furthermore, populations which have adopted "hip-safe" positioning have demonstrated a significant decrease in the incidence of DDH. Understanding this association is vital, since this is a modifiable risk factor, rectification of which can decrease the incidence of DDH.

CONCLUSION

Policy makers and governments must design educational campaigns tailored to their respective populations to increase awareness regarding the benefits of "hip-safe" techniques of infant positioning, since this simple intervention has the potential of decreasing the incidence of DDH.

Transition to a Safe Home Sleep Environment for the NICU Patient

Of the nearly 3.8 million infants born in the United States in 2018, 8.3% had low birth weight (<2500 g [5.5 lb]) and 10% were born preterm (gestational age of <37 completed weeks). Many of these infants and others with congenital anomalies, perinatally acquired infections, and other disease require admission to a NICU. In the past decade, admission rates to NICUs have been increasing; it is estimated that between 10% and 15% of infants will spend time in a NICU, representing approximately 500 000 neonates annually. Approximately 3600 infants die annually in the United States from sleep-related deaths, including sudden infant death syndrome International Classification of Diseases, 10th Revision (R95), ill-defined deaths (R99), and accidental suffocation and strangulation in bed (W75). Preterm and low birth weight infants are particularly vulnerable, with an incidence of death 2 to 3 times greater than healthy term infants. Thus, it is important for health care professionals to prepare families to maintain their infant in a safe sleep environment, as per the recommendations of the American Academy of Pediatrics. However, infants in the NICU setting commonly require care that is inconsistent with infant sleep safety recommendations. The conflicting needs of the NICU infant with the necessity to provide a safe sleep environment before hospital discharge can create confusion for providers and distress for families. This technical report is intended to assist in the establishment of appropriate NICU protocols to achieve a consistent approach to transitioning NICU infants to a safe sleep environment as soon as medically possible, well before hospital discharge.

Swaddling Practices in an Indian Institution: Are they Hip-Safe? A Survey of Paediatricians, Nurses and Caregivers

PURPOSE

Traditional infant swaddling or binding with hips and knees extended is a known risk factor for Developmental Dysplasia of the Hip (DDH), while 'hip-safe swaddling' with hips and knees flexed is believed to eliminate this risk. We conducted a survey to determine the prevalent practices for infant swaddling in India; why mothers practice swaddling and who teaches them; and whether Paediatricians, nurses and caregivers are aware of hip-safe swaddling.

METHODS

Anonymous one-time surveys were conducted in three groups-Paediatricians, Nurses and caregivers - at a tertiary-care, urban based, paediatric and maternity hospital.

RESULTS

Forty-five paediatricians, 219 nurses and 100 caregivers were surveyed. Ninety percent caregivers practiced traditional swaddling, for on average 10.2 hours a day, starting soon after birth, up to 4.2 months of life. Traditional swaddling was advocated by 99% nurses and 53% Paediatricians. Reasons for swaddling included sleep, warmth and the misbelief that the child's legs would remain bowed if not bound straight; contrarily few mothers (8%) avoided swaddling out of superstition. Mothers learnt swaddling mainly from relatives (94%) and nurses (64%). Most nurses (70%) had learnt the practice during nursing training. Only 6.6% Paediatricians, 4% caregivers and 0% nurses were aware of 'hip-safe swaddling'.

CONCLUSION

Traditional swaddling of infants is a practice deeply rooted in India, born out of misbeliefs, and propagated by lack of awareness. Training in hip-safe swaddling targeted at nurses and Paediatricians would be an effective initial step in creating awareness among mothers and changing their practices.

Infantile Colic: New Insights into an Old Problem

Infant colic is a characteristic group of behaviors seen in young infants. The most prominent feature is prolonged crying. Additional characteristics, including clenching of the fists and flexion of the hips, have led to the suggestion that these behaviors are related to abdominal discomfort. In this article, we show emerging evidence to support the concept that infant colic could represent gut inflammation and microbial dysbiosis that impacts brain function and even brain development.

Evaluation and treatment of developmental hip dysplasia in the newborn and infant

Developmental dysplasia of the hip (DDH) encompasses a spectrum of physical and imaging findings. The child's hip will not develop normally if it remains unstable and anatomically abnormal by walking age. Therefore, careful physical examination of all infants to diagnosis and treat significant DDH is critical to provide the best possible functional outcome. Regardless of the practice setting, all health professionals who care for newborns and infants should be trained to evaluate the infant hip for instability and to provide appropriate and early conservative treatment or referral.

To swaddle, or not to swaddle? Paleoepidemiology of developmental dysplasia of the hip and the swaddling dilemma among the indigenous populations of North America

OBJECTIVES

Clinical prevalence of developmental dysplasia of the hip (DDH) is high among modern indigenous populations of North America, yet no systematic study of the paleoepidemiology of this group exists. This study discusses the skeletal criteria, epidemiology, pathophysiology, and risk factors of DDH. A range of cases of DDH from an archaeological Native American population are described and the clinical and prehistoric prevalence of DDH among indigenous populations of North America are calculated and discussed within a biocultural perspective.

METHODS

Pelves of 390 adults from the Late Prehistoric (1490 B.P. ± 70) Buffalo site, West Virginia, were examined for DDH. Morphology of true and false acetabula was classified and other changes of the pelvis, lower limb, and spine were noted along with cranial deformation, providing evidence of infant restriction. Prevalence of DDH among living and archaeological indigenous peoples of North America were calculated and compared. Cranial deformation was assessed as evidence for swaddling.

RESULTS

DDH was identified in 18 adults from Buffalo, resulting in a minimum prevalence of 46.15 per 1,000, within the range reported in modern indigenous groups in North America. Most, but not all, of the DDH cases were associated with cranial deformation, but not all cases of cranial deformation were associated with DDH.

CONCLUSIONS

The etiology of DDH suggests that components of both genetic predisposition and swaddling practices have combined to create a high-risk environment for the development of DDH, contributing to high prevalence within archaeological populations, like Buffalo, and modern Indigenous groups of North America.

Joined at the hip? A paleoepidemiological study of developmental dysplasia of the hip and its relation to swaddling practices among indigenous peoples of North America

OBJECTIVES

Clinical prevalence of developmental dysplasia of the hip (DDH) is the highest among modern indigenous populations of North America, yet no systematic study of the paleoepidemiology of this group exists. This study discusses the skeletal criteria, epidemiology, pathophysiology, and risk factors for DDH. A range of cases of DDH from an archaeological Native American population are described, and the clinical and prehistoric prevalence of DDH among indigenous populations of North America are calculated and discussed within a biocultural perspective.

METHODS

Pelves of 390 adults from the Late Prehistoric (1490 BP ± 70) Buffalo site, West Virginia were examined for DDH. Morphology of true and false acetabula was classified and other changes of the pelvis, lower limb, and spine were noted along with cranial deformation, providing evidence of infant restriction. Prevalence of DDH among living and archaeological indigenous peoples of North America were calculated and compared.

RESULTS

DDH was identified in eighteen adults from Buffalo, resulting in a prevalence of 46.15, within the range reported in modern indigenous groups in North America. However, there is a significant difference between the DDH prevalence in prehistory and today in the target population.

CONCLUSIONS

Indigenous peoples of North America have the highest reported global prevalence of DDH today and in prehistory. The etiology of DDH suggests that components of both genetic predisposition and swaddling practices have combined to create a high-risk environment for the development of DDH, contributing to its high prevalence within archaeological populations, like Buffalo, and modern Native American/Aboriginal groups within North America.

The epidemiology and demographics of hip dysplasia

The etiology of developmental dysplasia of the hip (DDH) is unknown. There are many insights, however, from epidemiologic/demographic information. A systematic medical literature review regarding DDH was performed. There is a predominance of left-sided (64.0%) and unilateral disease (63.4%). The incidence per 1000 live births ranges from 0.06 in Africans in Africa to 76.1 in Native Americans. There is significant variability in incidence within each racial group by geographic location. The incidence of clinical neonatal hip instability at birth ranges from 0.4 in Africans to 61.7 in Polish Caucasians. Predictors of DDH are breech presentation, positive family history, and gender (female). Children born premature, with low birth weights, or to multifetal pregnancies are somewhat protected from DDH. Certain HLA A, B, and D types demonstrate an increase in DDH. Chromosome 17q21 is strongly associated with DDH. Ligamentous laxity and abnormalities in collagen metabolism, estrogen metabolism, and pregnancy-associated pelvic instability are well-described associations with DDH. Many studies demonstrate an increase of DDH in the winter, both in the northern and southern hemispheres. Swaddling is strongly associated with DDH. Amniocentesis, premature labor, and massive radiation exposure may increase the risk of DDH. Associated conditions are congenital muscular torticollis and congenital foot deformities. The opposite hip is frequently abnormal when using rigorous radiographic assessments. The role of acetabular dysplasia and adult hip osteoarthritis is complex. Archeological studies demonstrate that the epidemiology of DDH may be changing.
