Introduction
Physical activity is one of the basic needs for toddlers because it can been shown to potentially benefit children s physical, social and cognitive growth. Acute diseases are very common among toddlers, especially in Sub-Saharan Africa. The purpose of this study was to compare activity of healthy and acutely ill toddlers.
Methods
This study was a secondary analysis of the iLiNS-DOSE trial, which took place in Malawi during 2009-2012. The ActiGraph GT3X+ accelerometer was used to measure physical activity. Morbidity measurements were collected into a form by a research assistant together with a guardian s verbal report, based on the already filled Morbidity calendar. Days during which a child was suffering from any symptoms of diarrhoea, fewer or acute respiratory infection were counted as sick days. The main activity outcome was mean vector magnitude accelerometer counts/15s. The secondary outcome was % time spent in moderate-to-vigorous physical activity by the vertical axis. We compared the activity of a sick day and a healthy day in within-children and between children.
Results
Altogether 1 932 participants were enrolled in the iLiNS-DOSE study, 279 children were included in this sub-study and contributed to 843 (41%) days with symptoms (297 participants of within-children and between-children analyses and 729 participants of all healthy or sick during the measurement week analyses). We found the mean accelerometer counts on the within-children analysis in healthy days 303, SD 67 and on days with symptoms 305, SD 70 (difference 2, 95% Cl -6 to 3, p=0.48). The mean accelerometer counts on between-children analysis in healthy days 305, SD 79, and on days with symptoms 303, SD 76, (difference - 2, 95% Cl -4 to 10, p=0.43).
Conclusion
No difference was found in physical activity between days with acute diseases and days without symptoms among Malawian toddlers.
