Nutritional survey of children and adolescents with myelomeningocele (MMC): overweight associated with reduced energy intake

Metabolic Syndrome in Children With Myelomeningocele and the Role of Physical Activity: A Narrative Review of the Literature

Objectives

The purpose of this review is to describe the current scientific literature on the prevalence of metabolic syndrome in children with myelomeningocele and to gain insight into the baseline levels of aerobic fitness, endurance, and strength in this population in order to identify gaps in knowledge, suggest potential primary prevention strategies, and provide recommendations for future studies.

Methods

A literature review of articles published in English and French between 1990 and April 2020 was conducted.

Results

Obese adolescents with myelomeningocele have an increased prevalence of components of the metabolic syndrome. Children and adolescents with myelomeningocele have decreased aerobic fitness and muscular strength, decreased lean mass, and increased fat mass, all of which, when combined with higher levels of physical inactivity, put them at higher risk of developing metabolic syndrome and cardiovascular diseases.

Conclusion

Until more research is conducted, addressing weight-related challenges and promoting healthy habits (such as optimal activity levels) could be easily integrated into yearly myelomeningocele clinics. An actionable suggestion might be to systematically weigh and measure children in these clinics and utilize the results and trends as a talking point with the parents and children. The follow-up appointments could also be used to develop physical activity goals and monitor progress. We recommend that the health care practitioner tasked with this intervention (physician, nurse, etc.) should be aware of locally available accessible sports platforms and have knowledge of motivational interviewing to facilitate removal of perceived barriers to physical activity.

Basics of bone metabolism and osteoporosis in common pediatric neuromuscular disabilities

Bone modeling is a process that starts with fetal life and continues during adolescence. Complex factors such as hormones, nutritional and environmental factors affect this process. In addition to these factors, physical conditioning and medications that have toxic effects on bony tissue should be carefully considered in patient follow-up. Osteoporosis is a significant problem in pediatric population because of ongoing growth and development of skeletal system. Two types of osteoporosis are primary and secondary types and children with neuromuscular disabilities constitute a major group with secondary osteoporosis. Low bone mass in patients with cerebral palsy, spina bifida, and Duchenne muscular dystrophy cause increased bone fragility in even slight traumas. Maximizing peak bone mass and prevention of bone loss are very important to reduce the fracture risk in neuromuscular diseases. This article aims to review the determinants of bone physiology and bone loss in children with cerebral palsy, spina bifida, and Duchenne muscular dystrophy.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Obesity and myelomeningocele: anthropometric measures

OBJECTIVE

To evaluate the appropriate use of arm span measurements as a substitute for height/linear length to evaluate obesity in people with myelomeningocele by comparing calculated body mass indices (BMIs) with recently published BMI graphs by the Centers for Disease Control and Prevention (CDC) and National Center for Health Statistics standards (NCHS) published in 2000.

STUDY DESIGN

Retrospective analysis of collected data on patients seen in the University of Washington Birth Defects Clinic from July 1, 1965, through June 1, 2008. Observations included degree of paralysis, presence of scoliosis, height (linear length), weight, and arm span. We compared published CDC/NCHS BMIs with our data using both height and arm span in place of height/linear length. There were 14,701 measures collected during 4968 visits from 709 patients. Mean values were calculated using age, gender, and lesion level as independent variables.

RESULTS

Comparison of BMI means of patients with myelomeningocele suggests that our observations using arm span and height are comparable with the CDC/NCHS BMI means using height for the 2 least paralyzed groups but not for those groups with paralysis from high-level lesions that are more likely to exhibit lower extremity deformities or scoliosis.

CONCLUSIONS

Published CDC/NCHS graphs, with their percentiles, are appropriate for estimating normal growth by BMI for children born with myelomeningocele when arm span is substituted for length if severe body differences due to high-level paralysis are taken into consideration.

Body composition and resting energy expenditure in patients aged 11 to 21 years with spinal cord dysfunction compared to controls: comparisons and relationships among the groups

OBJECTIVES

To compare body composition in patients aged 11 to 21 years with spinal dysfunction due to spinal cord injury (SCI) and spina bifida (SB) vs. able-bodied control (CTRL) and able-bodied overweight (OW) groups and to examine the relationships between resting energy expenditure (REE) and total lean mass (TLM) in the SCI, SB, CTRL, and OW groups.

METHODS

Two hundred fifteen subjects, including 85 CTRL, 31 OW, 33 SCI, and 66 SB, were evaluated. Body composition was estimated by dual energy x-ray absorptiometry (DXA). Measurements included height, weight, total lean mass (TLM), fat tissue mass (FTM), body mass index (BMI), BMI percentile (BMI%tile), and % fat. Resting energy measurements were obtained in fasting subjects with an open-circuit indirect calorimeter.

RESULTS

There were gender differences in height, weight, BMI, TLM, fat mass, % fat, and REE. The REE in the SCI and SB groups was significantly different from that in the CTRL and OW groups, but no significant difference was found between the SCI and SB groups. The SB group had significantly higher REE/TLM ratios than did the other groups. The % fat was significantly higher in the SB and OW groups as compared to the CTRL and SCI groups. TLM was significantly higher in CTRL and OW groups as compared to SCI and SB groups, with the lowest TLM found in the SB group.

CONCLUSION

Patients aged 11 to 21 years with SB or SCI have significant lean tissue mass deficits by DXA as compared to able-bodied CTRL and OW groups, with the greatest deficits in total lean mass measured in SB. The absolute REE values were significantly reduced in both SCI and SB groups in association with their lean tissue deficits. Interestingly, REE/TLM ratios were remarkably constant in the CTRL, OW, and SCI groups but significantly elevated in the SB group. One would expect an even greater degree of adiposity in the SB group if their REE/TLM ratios were not elevated relative to those without congenital paralysis.

Osteoporosis in Adults With Meningomyelocele: An Unrecognized Problem at Rehabilitation Clinics

OBJECTIVES

To assess the prevalence of osteoporosis and osteopenia in adults with meningomyelocele and to explore whether neurologic level, ambulatory status, and other medical problems are associated with bone mineral density (BMD).

DESIGN

A cross-sectional study, including a self-administered questionnaire and clinical assessment.

SETTING

Outpatient referral clinic in Sweden.

PARTICIPANTS

Twenty-one adults (mean age, 30 y) with meningomyelocele admitted to the Young Adult Teams in Göteborg and Boras, Sweden.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

BMD in the lumbar spine and hip and forearm measured with dual x-ray absorptiometry.

RESULTS

Seven (33%) subjects had osteoporosis in at least 1 of the measured sites. Three patients had osteopenia and 2 had osteoporosis in the lumbar spine. Among the 15 subjects whose BMD of the hip region could be reliably measured, 7 (47%) had osteoporosis in the femoral neck or trochanteric region of the hip. Subjects with other medical problems commonly occurring in meningomyelocele had lower BMD in the femoral neck and trochanteric region of the hip than subjects without such factors. Ambulation alone showed only a tendency to be associated with BMD of the femoral neck, whereas the effect of other medical risk factors on BMD of the femoral neck was stronger among the nonambulators than the ambulators.

CONCLUSIONS

Our results show that osteoporosis is a medical problem to be considered when treating and rehabilitating patients with meningomyelocele.
