RÉSUMÉ
Since the first operational definition of cognitive frailty was proposed by the expert consensus group of the International Academy of Nutrition and Aging and the International Association of Gerontology and Geriatrics in 2013, frailty and neurocognitive assessment has become the standard diagnostic tool.Since then, the reported prevalence in the literature for cognitive frailty in community-dwelling elderly people vary by dozens of times, as a result of different scales and diagnostic cut-off points, seriously affecting health decision-making.This article reviewed the current literature with a focus on the re-recognition of the clinical significance of cognitive frailty, the limitations of existing assessment tools for diagnosis, and possible solutions in the future.
RÉSUMÉ
Objective@#To understand physical health of pre school children aged 3-6, so as to analyze the early life influencing factors, and to provide a reference for physical health promotion of preschool children.@*Methods@#The method of random sampling was used to select 1 580 preschoolers aged from 3-6 in Guangzhou. National physical health test and questionnaire survey were conducted to assess physical health.@*Results@#The physical fitness pass rate of preschool children was 87.2%, among which the excellent rate was 30.8%. With the increase of age, the rate of good physique of both boys and girls increased. There were statistical differences in body shape indexes (except dermal fold thickness) between male and female children at all ages ( P <0.01). The rate of overweight and obesity was 14.7%, which was higher in boys (17.2%) than in girls (12.0%). There were significant differences between overweight and non overweight obese people( χ 2=4.84，3.96，5.73，4.85， P <0.05). Logistic regression showed that preterm birth was negatively correlated with the rate of good physique of preschool children ( OR=0.81, P <0.05). There was a positive correlation between birth weight greater than gestational age and the rate of physical fitness of preschool children ( OR=1.37, P <0.05).@*Conclusion@#Preschool children aged 3-6 years old in Guangzhou have poor physical health overall, and the rate of good physical health is related to factors such as preterm gestational week in early life delivery and birth weight greater than the gestational age.
