Happy feet, food & fat

Voor het eerst in de geschiedenis van de mensheid zijn er meer mensen met overgewicht dan met ondervoeding. Overgewicht is in snel tempo toegenomen en is een van de grootste maatschappelijke (gezondheids)problemen van deze tijd. Overgewicht heeft ondervoeding overschaduwd. In "The land of plenty"’ is geen gebrek meer, en dus geen ondervoeding zou je verwachten. Ondervoeding blijkt echter ook in deze tijd nog steeds een van de grootste maatschappelijke (gezondheids). Door inactiviteit of door ziekte kan spiermassa afnemen en wordt het steeds lastiger ondervoeding door de laag vet heen te ontdekken. Het aanpakken van overgewicht en ondervoeding door de professional vergt goed gewichtsmanagement. Voeding en beweging spelen hierbij een cruciale rol. Energie uit de voeding is gerelateerd aan vetmassa, en eiwit uit de voeding en beweging is gerelateerd aan spiermassa

Agreement of measurement of body composition with seven alternative electrode positions on the hand compared to the standard protocol with single-frequency 50 kHz bioelectrical impedance in healthy young adults

RationaleIn bioelectrical impedance analysis (BIA) measurements, one pair of electrodes is typically placed dorsal on the right hand (position A) and one pair on the foot. In patients with fragile skin, scars or wounds, this dorsal hand placement is not always possible. This study compares agreement of BIA measurements at seven alternative placements with position A. MethodsBIA measurements were performed with the Bodystat-500 using eight combinations of hand electrodes: at the dorsal side of the hand (position A) or dorsal side hand-forearm (position B and C); at the palmar side of the hand (position D) or palmar side hand-forearm (position E and F) or mixed palmar-dorsal side of the hand (position G and H). ICCs were used to compare alle outcomes to position A. Changes in fat mass ∆FM, fat-free mass ∆FFM and appendicular skeletal muscle mass ∆ASMM were calculated using Kyle’s formula.ResultsSeventy healthy Caucasian participants were measured: median age 22 years, IQR 21-23; mean BMI 22.8 ± 2.5 kg/m². Electrode positions D,G and H showed an ICC 0.99-1.00 for ∆FM, ∆FFM and ∆ASMM with minimal changes in ∆FFM and ∆FM: 0.1–0.4 kg ± 0.3 kg and ∆ASMM: 0.0–0.2 kg ± 0.2 kg. Measurements at position B, C, E, and F showed significant and clinically relevant differences with ∆FM and ∆FFM: 3.8–4.0 kg ± 1.1 kg and ∆ASMM: 2.0–2.1 kg ± 0.6 kg, with ICCs 0.96-0.97.ConclusionAlternatively to the typical electrode placement on the dorsal side of the hand, this study demonstrates that three alternative placements results in an excellent agreement with only minimal changes in FFM, FM and ASMM. In practice, placing electrodes at more proximal positions on the forearm should be avoided. Alternatively, we recommend a mixed or palmar electrode placement on the hand.

Format zorgpad Voeding bij kanker

Het zorgpad ‘Voeding bij kanker’ beschrijft het (logistiek) pad dat de oncologische patiënt doorloopt binnen de voedingszorg vanaf het moment dat screening op behoefte aan voedingszorg plaatsvindt en verwijzing naar de diëtist tot en met follow-up of palliatieve fase. Hierbij zijn het format en de indeling aangehouden van de IKNL-formats van (niet-)tumorspecifieke zorgpaden

The effects of a preschool-based intervention for Early Childhood Education and Care teachers in promoting healthy eating and physical activity in young children: A cluster randomised controlled trial

The need for excess weight gain prevention in disadvantaged young children is widely recognised. Early Childhood Education and Care teachers are potential key actors in early interventions to prevent overweight and obesity. This study examines the effects of a preschool-based intervention for teachers in promoting healthy eating and physical activity in young children. A cluster randomised controlled trial was conducted at 41 preschools in a deprived area of Amsterdam, The Netherlands. The intervention consisted of 2 programmes that were applied in succession: A Healthy Start and PLAYgrounds for TODdlers. The study period was 9 months. Primary outcomes were assessed via questionnaires and included teachers’ knowledge, attitude, food/activity-related practices, and level of confidence in promoting healthy behaviours. Secondary outcomes in this study were teachers’ and children’s BMI (z-score), body composition, dietary intake and physical activity level. Intention-to-treat analyses were performed using linear mixed models. In total, 115 teachers and 249 children (mean age 3.0 (0.2) years) were included. A positive effect on teachers’ knowledge about the Dutch dietary guidelines was found after the programme A Healthy Start (difference = 1.38; 1-sided 95% CL = 0.29; p = 0.02). This effect was not sustained at 9 months (difference = 0.34; 1-sided 95% CL = -0.76; p = 0.31). The overall intervention had a positive effect on 3 of the 5 attitude statements regarding a healthy lifestyle (difference ranged from 0.34 to 0.55) and on the practice scale Activity-related-Modelling (difference = 0.16; 1-sided 95% CL = 0.06; p = 0.01). No intervention effects were observed on food-related practice scales and the level of confidence in promoting healthy behaviours. At this stage, no effects were seen on teachers’ and children’s BMI (z-score). This study contributes to the professional development of Early Childhood Education and Care teachers and addresses the call for interventions to prevent overweight/obesity and to minimise health inequalities in young children.

Bio-impedantiemeting in de eerste lijn

Naar aanleiding van het overzichtsartikel in het NTVD nr. 5, 2009 ontstond er discussie over het wel of niet geschikt zijn van bio-impedantiemeting ter bepaling van de lichaamssamenstelling in de eerstelijnsgezondheidszorg. De discussie wordt hier verder gevoerd.
