Validation of the SenseWear Mini activity monitor in 5-12-year-old children.

ABSTRACT: OBJECTIVES:This study aimed to validate SenseWear Mini software algorithm versions 2.2 (SW2.2) and 5.2 (SW5.2) for estimating energy expenditure (EE) in children. DESIGN:Laboratory-based validation study. METHODS:57 children aged 5-12 y completed a protocol involving 15 semi-structured sedentary (SED), light-intensity (LPA), and moderate- to vigorous-intensity (MVPA) physical activities. EE was estimated using portable indirect calorimetry (IC). The accuracy of EE estimates (kcal·min-1) from SW2.2 and SW5.2 were examined at the group level and individual level using the mean absolute percentage error (MAPE), Bland-Altman plots and equivalence testing. RESULTS:MAPE values were lower for SW5.2 (30.1±10.7%) than for SW2.2 (44.0±6.2%). Although mean differences for SW5.2 were smaller than for SW2.2 during SED (-0.23±0.22 vs. -0.61±0.20kcal·min-1), LPA (-0.69±0.76 vs. -1.07±0.46kcal·min-1) and MVPA (-2.22±1.15 vs. -2.57±1.15kcal·min-1), limits of agreement did not decrease for the updated algorithms. For all activities, SW2.2 and SW5.2 were not equivalent to IC (p>0.05). Errors increased with increasing intensity. CONCLUSION:The current SenseWear Mini algorithms SW5.2 underestimated EE. The overall improved accuracy for SW5.2 was not accompanied with improved accuracy at the individual level and EE estimates were not equivalent to IC.

Project description:ObjectivesNationwide prevention programs in Germany aim to promote oral health. The group prevention program starts in kindergarten and ends when the children are about 12 y old. While in a recent study, toothbrushing behavior of 12-y-old children was analyzed, the present study's objective was to examine the children's ability to achieve oral cleanliness and to analyze how toothbrushing behavior and compliance with the toothbrushing recommendations taught in the group prevention programs predict oral cleanliness.MethodsTwelve-year-old randomly selected children (N = 174) were asked to brush their teeth to the best of their abilities, and simultaneously a video was recorded for behavioral analyses. Plaque levels were measured before and immediately after toothbrushing. In addition, dental status and gingival bleeding were assessed.ResultsAfter brushing to the best of their abilities, there was plaque on 50% (±24.72%) of all measured sites at the gingival margin (Marginal Plaque Index). Regression analyses revealed approximately 22% of the variance of marginal plaque on the outer surfaces to be explained by the time brushed by circular movements (β = -0.41;P < 0.001) and the number of sextants brushed for at least 7.5 s (β = -0.171; P < 0.05). Circular movements explained most additional variance (ΔR2 = 0.113; P < 0.001). With respect to inner surfaces, none of the behavioral aspects explained any variance of oral cleanliness.ConclusionDespite regular group prevention measures, 12-y-old children show limited skills to clean their teeth adequately. Furthermore, none of the recommended behaviors relates to oral cleanliness after toothbrushing at inner surfaces. As a consequence, it is necessary to explore further which behavioral sequences effectively improve oral cleanliness.Knowledge transfer statementThis study illustrates that children's compliance to toothbrushing recommendations is not necessarily related to toothbrushing effectiveness. Clinicians should therefore assess the effectivity of recommendations individually and provide individual guidance for improvement.

Project description:BackgroundThe Swedish Quality Registry for caries and periodontal disease (SKaPa) automatically collects data on caries and periodontitis from patients' electronic dental records. Provided the data entries are reliable and accurate, the registry has potential value as a data source for registry-based research. The aim of this study was to evaluate the reliability and accuracy of the SKaPa registry information on dental caries in 6- and 12-year-old children.MethodThis diagnostic accuracy study compared dental caries data registered at an examination with dental health status registered in the patient's electronic dental records, and with corresponding data retrieved from the SKaPa registry. Clinical examinations of 170 6- and 12-year-old children were undertaken by one of the researchers in conjunction with the children's regular annual dental examinations where the number of teeth were registered, and dental caries was diagnosed using ICDAS II. Teeth with fillings were defined as filled and were added to the ICDAS II score and subsequently dft/DFT was calculated for each individual. Cohen's Kappa, the intraclass correlation coefficient (ICC), and sensitivity and specificity were calculated to test the agreement of the 'decayed and filled teeth' in deciduous and permanent teeth (dft/DFT) from the three sources.ResultsCohen's Kappa of the dft/DFT-values was calculated to 0.79 between the researcher and the patient record, to 0.95 between patient dental record and SKaPa, and to 0.76 between the researcher and SKaPa. Intraclass correlation coefficient (ICC) was calculated to 0.96 between the researcher and the patient journal, to 0.99 between the patient dental record vs. SKaPa, and to 0.95 between the researcher and SKaPa.ConclusionThe SKaPa registry information demonstrated satisfactory reliability and accuracy on dental caries in 6- and 12-year-old children and is a reliable source for registry-based research. Trial registration The study was registered in Clinical Trials ( www.ClinicalTrials.gov , NCT03039010).
