Trial Outcomes & Findings for Body Composition in Infants With Klinefelter Syndrome and Effects of Testosterone Treatment (NCT NCT02408445)

NCT ID: NCT02408445

Last Updated: 2020-04-15

Results Overview

Body fat percentage will be measured using air displacement plethysmography (PEA POD) at the beginning and end of the study period. Age and sex-normed z-scores will be calculated. The Z-score indicates the number of standard deviations away from the mean. A Z-score of 0 is equal to the mean with negative numbers indicating values lower than the mean and positive values higher. Change in the z-score over time, if following a normal growth curve, is 0. Positive change in z-scores indicates a gain in body fat above growth typically expected. Negative change in z-scores indicates a gain in body fat that is less than typically expected.

SECONDARY outcome

Timeframe: 3 months

Muscle tone and motor development will be assessed by an occupational therapist using the standardized Alberta Infant Motor Scale (AIMS). The AIMS scale measures infant motor maturation from birth until the age of independent walking. An occupational therapists assesses 58 motor behavior items in 4 position categories: prone (21 items), supine (9 items), sitting (12 items) \& standing(16 standing). Each item receives one point (range of raw scores 0-58), with higher scores indicating more skills acquired. For change in scores, the raw score at 3 months was subtracted from the baseline raw score.

SECONDARY outcome

Timeframe: 3 months

Population: Data for this measurement was not collected for any of the participants.

Muscle tone and motor development will be assessed by an occupational therapist using the standardized Movement Assessment of Infants (MAI). The MAI evaluates four domains: muscle tone, primitive reflex, automatic reactions and volitional movement. All items are scored 1-5 and summed to generate a "Total Risk Score". Lower scores indicate better function, and Total Risk Scores of 8 or more indicate high risk.

SECONDARY outcome

Timeframe: 3 months

Motor development will be assessed by an occupational therapist using the standardized Peabody Developmental Motor Scales 2. Standard scores are normalized to age with a mean of 100 and standard deviation of 15. Change in standard score was calculated as the differences between the subject's standard score at 3 months minus the standard score at baseline. A positive change in standard scores would indicate greater growth on the measure relative to peers, while a negative number would indicate slower growth on the measure relative to peers.
