Early prediction of physical activity level 1 year after stroke: a longitudinal cohort study.

ABSTRACT: OBJECTIVE:To investigate which variables present prior and early after stroke may have an impact on the level of physical activity (PA) 1?year poststroke. DESIGN:Prospective longitudinal cohort and logistic regression analysis. SETTING:Stroke Unit at Sahlgrenska University Hospital, Gothenburg, Sweden. PARTICIPANTS:117 individuals as part of the Stroke Arm Longitudinal Study (SALGOT) admitted to the stroke unit during a period of 18 months were consecutively recruited. The inclusion criteria were: first-time stroke, impaired upper extremity function, admitted to the stroke unit within 3 days since onset, local residency and ?18 years old. The exclusion criteria were: upper extremity condition or severe multi-impairment prior to stroke, short life expectancy and non-Swedish speaking. 77 participants followed up at 1?year poststroke were included in the analysis. PRIMARY OUTCOME:PA level 1?year after stroke was assessed using a 6-level Saltin-Grimby Scale, which was first dichotomised into mostly inactive or mostly active and second into low or moderate/high level of PA. RESULTS:Being mostly inactive 1?year after stroke could be predicted by age at stroke onset (OR 1.07, 95%?CI 1.00 to 1.13, p=0.041), functional dependency at discharge (OR 7.01, 95%?CI 1.73 to 28.43, p=0.006) and prestroke PA (OR 7.46, 95%?CI 1.51 to 36.82, p=0.014). Having a low level of PA 1?year after stroke could be predicted by age at stroke onset (OR 1.13, 95%?CI 1.06 to 1.21, p<0.001) and functional dependency at discharge (OR 3.62, 95%?CI 1.09 to 12.04, p=0.036). CONCLUSIONS:Previous low level of PA, older age and functional dependency all provided value in predicting low PA 1?year after stroke. These results indicate that age and simple clinical evaluations early after stroke may be useful to help clinicians identify persons at risk of being insufficiently active after stroke. Further research is needed to clarify if these findings may apply to the large population of stroke survivors. TRIAL REGISTRATION NUMBER:ClinicalTrials.gov (NCT01115348).

Project description:BackgroundKnowledge on longitudinal patterns and related factors of young children's physical activity (PA) is still scarce. Therefore, the aim of this study was to examine patterns and changes of accelerometer-measured PA over time in two to six-year-old children. Furthermore, the aim was to investigate if parental PA, socioeconomic status, sex, weight status, and motor skills are related to child PA over time, using prospective cohort data from a clustered randomized controlled trial.MethodsOne hundred and six children (52% girls) and their parents had PA measured yearly from age two to six with an Actigraph GT3X. The actigraph was worn on the non-dominant wrist for one week; anthropometric data and motor skills, as well as background information, was collected simultaneously. The outcome was counts per minute from the vector magnitude, and linear mixed-effect models were used to answer the research questions.ResultsAmong the children, accelerometer-measured PA increased on average by 11% per year from two years of age (mean 3170 cpm (3007-3334 95% CI)) onwards to six years of age (mean 4369 cpm (4207-4533 95% CI)). From three years of age, children were more active on weekdays than on weekend days. The rate of difference varied across low, medium, and highly active children (based on tertiles). No significant differences in weekdays/weekend PA among the lowest active children was found. Despite this, they were still significantly less active on weekend days than the most active children. Maternal, but not paternal PA was found to be significantly positively related to child PA over time, with a medium to large effect size. But no significant relationships were found between child PA and sex, weight status, or socioeconomic status.ConclusionsPA increased on average with 11% per year, similarly for boys and girls. From three years of age children were more active during weekdays than weekend days. These results indicate that child PA benefits from active stimulation by parents and care takers already from early ages. It is important to identify attributes of possible intervention designs for weekend days for families with young children as well as characterize the least active children.Trial registrationEarly STOPP was prospectively registered in the clinical trials registry: clinicaltrials.gov , ID NCT01198847.

Project description:BackgroundSufficient physical activity (PA) during pregnancy is beneficial for a woman's health; however, the PA levels of Chinese women at different pregnancy stages are not clear. The aim of our study was to investigate PA changes during pregnancy and the association of population characteristics with PA change among Chinese women.MethodsData were obtained from 2485 participants who were enrolled in the multicentre prospective Chinese Pregnant Women Cohort Study. PA level was assessed in early pregnancy (mean = 10, 5-13 weeks of gestation) and again in mid-to-late pregnancy (mean = 32, 24-30 weeks of gestation) using the International Physical Activity Questionnaire short form (IPAQ-SF). Sufficient PA (≥ 600 MET min/week) in early pregnancy and insufficient PA in mid-to-late pregnancy indicated decreasing PA. Insufficient PA in early pregnancy and sufficient PA in mid-to-late pregnancy indicated increasing PA. The associations between demographic, pregnancy and health characteristics and PA changes were examined by multivariable logistic regression.ResultsTotal energy expenditure for PA increased significantly from early (median = 396 MET min/week) to mid-to-late pregnancy (median = 813 MET min/week) (P < 0.001), and 55.25% of the participants eventually had sufficient PA. Walking was the dominant form of PA. Women with sufficient PA levels in early pregnancy were more likely to have sufficient PA in mid-to-late pregnancy (OR 1.897, 95% CI 1.583-2.274). Women in West China and those in Central China were most and least likely, respectively, to have increasing PA (OR 1.387, 95% CI 1.078-1.783 vs. OR 0.721, 95% CI 0.562-0.925). Smoking was inversely associated with increasing PA (OR 0.480, 95% CI 0.242-0.955). Women with higher educational levels were less likely to have decreasing PA (OR 0.662, 95% CI 0.442-0.991).ConclusionsPA increased as pregnancy progressed, and walking was the dominant form of PA among Chinese women. Further research is needed to better understand correlates of PA change.
