Energy requirements in preschool-age children with cerebral palsy

BACKGROUND There is a paucity of data concerning the energy requirements (ERs) of preschool-age children with cerebral palsy (CP), the knowledge of which is essential for early nutritional management. OBJECTIVE We aimed to determine the ERs for preschool-age children with CP in relation to functional ability, motor type, and distribution and compared with typically developing children (TDC) and published estimation equations. DESIGN Thirty-two children with CP (63% male) of all functional abilities, motor types, and distributions and 16 TDC (63% male) aged 2.9-4.4 y participated in this study. The doubly labeled water method was used to determine ERs. Statistical analyses were conducted by 1-factor ANOVA and post hoc Tukey honestly significant difference tests, independent and paired t tests, Bland and Altman analyses, correlations, and multivariable regressions. RESULTS As a population, children with CP had significantly lower ERs than did TDC (P < 0.05). No significant difference in ERs was found between ambulant children and TDC. Marginally ambulant and nonambulant children had ERs that were ∼18% lower than those of ambulant children and 31% lower than those of TDC. A trend toward lower ERs with greater numbers of limbs involved was observed. The influence of motor type could not be determined statistically. Published equations substantially underestimated ERs in the nonambulant children by ∼22%. CONCLUSIONS In preschool-age children with CP, ERs decreased as ambulatory status declined and more limbs were involved. The greatest predictor of ERs was fat-free mass, then ambulatory status. Future research should build on the information presented to expand the knowledge base regarding ERs in children with CP. This trial was registered with the Australian New Zealand Clinical Trials Registry as ACTRN 12612000686808.

The Association between the Mediterranean Dietary Pattern and Cognitive Health: A Systematic Review

The ageing population is accompanied by increased rates of cognitive decline and dementia. Not only does cognitive decline have a profound impact on an individual’s health and quality of life, but also on that of their caregivers. The Mediterranean diet (MD) has been known to aid in reducing the risk of cardiovascular diseases, cancer and diabetes. It has been recently linked to better cognitive function in the elderly population. The purpose of this review was to compile evidence based data that examined the effect of adherence to the MD on cognitive function and the risk of developing dementia or Alzheimer’s disease. This review followed PRISMA guidelines and was conducted using four databases and resulted in 31 articles of interest. Cross-sectional studies and cohort studies in the non-Mediterranean region showed mixed results. However, cohort studies in the Mediterranean region and randomized controlled trials showed more cohesive outcomes of the beneficial effect of the MD on cognitive function. Although more standardized and in-depth studies are needed to strengthen the existing body of evidence, results from this review indicate that the Mediterranean diet could play a major role in cognitive health and risk of Alzheimer’s disease and dementia.

The use of bioelectrical impedance analysis to estimate total body water in young children with cerebral palsy

BACKGROUND & AIMS Body composition assessment is an essential component of nutritional evaluation in children with cerebral palsy. This study aimed to validate bioelectrical impedance to estimate total body water in young children with cerebral palsy and determine best electrode placement in unilateral impairment. METHODS 55 young children with cerebral palsy across all functional ability levels were included. Height/length was measured or estimated from knee height. Total body water was estimated using a Bodystat 1500MDD and three equations, and measured using the gold standard, deuterium dilution technique. Comparisons were made using Bland Altman analysis. RESULTS For children with bilateral impairment, the Fjeld equation estimated total body water with the least bias (limits of agreement): 0.0 L (-1.4 L to 1.5 L); the Pencharz equation produced the greatest: 2.7 L (0.6 L-4.8 L). For children with unilateral impairment, differences between measured and estimated total body water were lowest on the unimpaired side using the Fjeld equation 0.1 L (-1.5 L to 1.6 L)) and greatest for the Pencharz equation. CONCLUSIONS The ability of bioelectrical impedance to estimate total body water depends on the equation chosen. The Fjeld equation was the most accurate for the group, however, individual results varied by up to 18%. A population specific equation was developed and may enhance the accuracy of estimates.

Differences in body composition according to functional ability in preschool-aged children with cerebral palsy

BACKGROUND & AIMS Altered body composition is evident in school children with cerebral palsy (CP). Fat free mass and fat mass amounts differ according to functional ability and compared to typically developing children (TDC). The extent to which body composition is altered in preschool-aged children with CP is unknown. We aimed to determine the fat free mass index (FFMI) and body fat percentage (BF%) of preschool-aged children with CP and investigate differences according to functional ability and compared to TDC. METHODS Eighty-five children with CP (68% male) of all functional abilities, motor types and distributions and 16 TDC (63% male) aged 1.4-5.1 years participated in this cross-sectional study. Body composition was determined via isotope dilution. Children with CP were classified into groups based on their Gross Motor Function Classification System (GMFCS) level. Statistical analyses were via ANOVA, ANCOVA, post-hoc Tukey HSD tests, independent t-tests and multiple regressions. RESULTS There were no significant differences in FFMI or BF% when comparing all children with CP to TDC. Children classified as GMFCS levels III, IV and V had significantly lower FFMI levels compared to children classified as GMFCS I and II (p < 0.05). Children of GMFCS IV and V had the highest mean (± SD) BF% of all children (24.6% (± 10.7%)), significantly higher than children of GMFCS I and II (18.6% (± 6.8%), p < 0.05). CONCLUSIONS Altered body composition is evident in preschool-aged children with CP, with a trend towards lower FFMI levels and greater BF% across functional ability levels from GMFCS I to V. Further research is required to determine optimal body composition parameters and investigate contributing factors.

Relationships between Dietary Intake and Body Composition according to Gross Motor Functional Ability in Preschool-Aged Children with Cerebral Palsy

Background/Aims: We aimed to determine the relationships between energy intake, macronutrient intake and body composition in preschool-aged children with cerebral palsy (CP) according to gross motor functional ability in comparison with typically developing children (TDC). Methods: Seventy-three children with CP (70% male) of all functional abilities and 16 TDC (63% male) aged 2.8 ± 0.9 years participated in this study. Dietary intake was measured via a validated 3-day weighed food record. Body composition was determined via isotope dilution techniques. Results: There was a significant relationship between energy intake and fat-free mass index, which was stronger in TDC compared to children with CP. There were no significant correlations between other dietary intake and body composition variables, despite differences in body composition as ambulatory status declined. Non-ambulant, tube-fed children had significantly lower protein intakes compared to orally fed children. No other differences in macronutrient intake between children with CP and TDC were apparent. Conclusions: Results suggest that relationships between dietary intake and body composition are not evident in this population, but develop over time. Physical activity levels may have a greater impact on body composition at this age. Longitudinal research is required to examine these factors.

A review of energy intake measures used in young children with cerebral palsy

The aim of this review was to evaluate the psychometric properties and clinical utility of energy intake measures used in young children with cerebral palsy (CP). Five databases were searched for relevant literature, and measures were included if they (1) directly measured energy intake in kilojoules/kilocalories per day; (2) had published data in kilojoules/kilocalories per day for children with CP from birth to 5 years; and (3) at least 40% of participants had a diagnosis of CP. Three measures met criteria: a 3‐day weighed food record, a 3‐day estimated food record, and a 7‐day estimated food record. Included measures were evaluated on their characteristics, intended outcome, and validity. Reliability and responsiveness were not reported for any measure. Currently there is no dietary methodology that has proven reliability or repeated validity in young children with CP. Clinicians and researchers should not rely on current methodologies until further evaluation.

The validity of dietary assessment methods to accurately measure energy intake in children and adolescents who are overweight or obese: a systematic review

The accurate assessment of energy intake in children and adolescents is an important outcome measure for clinical and population-based research. This systematic review aimed to determine the validity of dietary assessment methods to measure energy intake in children and adolescents who are classified as overweight or obese by comparison with doubly labelled water. Five electronic databases were searched using keywords. Of the 5263 papers identified, seven papers describing six studies met the inclusion criteria. Studies were included in the review if participants were classified as overweight or obese, aged 0–18 years old, if they estimated energy intake via a dietary assessment method and if they compared this to total energy expenditure measured via the doubly labelled water method. All studies were cross-sectional in nature, and each used one dietary assessment method, including 14-day-food record (FR; n = 1), 24 h dietary recall (n = 1), 8-day FR (n = 1), 9-day FR (n = 1), 3-day FR (n = 1) and diet history interview (n = 1). Sample sizes ranged from 9 to 59 participants, with the majority of studies including less than 30 participants (n = 4). Mis-reporting was evident in all of the studies, with under-reporting (n = 5) more frequent than over-reporting (n = 1). Findings from this review suggest that a 24-h dietary recall and diet history interview were the most accurate methods at the group level for children aged 4–14 years, where the parent or combined child and parent were the reporters.

The Need for Early Referral: Characteristics of Children and Adolescents Who Are Overweight and Obese Attending a Multidisciplinary Weight Management Service

There is a need to examine the issue of childhood obesity from a systems perspective. This study aimed to describe the baseline characteristics of children attending pediatric multidisciplinary weight management services and understand how this information will inform future service delivery. A total of 51 children and adolescents who were overweight and obese (27 male) and aged between two and 16 years participated. Body size measures such as body mass index (BMI) and body fat percentage were collected. Participants and their parents/guardians also completed questionnaires on dietary intake, behaviors and habits, physical activity and health-related quality of life. A total of 72% of participants were classified as morbidly obese. Adolescents had significantly lower scores for overall diet, physical activity and particular health-related quality of life scores. No significant correlations were found between BMI z-scores and diet, physical activity and health-related quality of life. In adolescents, correlations were detected between dietary scores and health-related quality of life. Results confirm the need to critically examine the current context to adapt and tailor interventions to individual circumstances, and when combined with focused referral, triaging and screening processes, should assist in delivering the right care at the right time.
