UNLABELLED
Until better measures have been accepted for wider use, the Mini-Mental State Examination (MMSE) will continue to be utilized. In this context, knowledge on characteristics and determinants of its distribution for the Brazilian population are particularly valuable. The present study aimed to evaluate, based on multivariate analysis, the independent effect of age, educational level and sex, and their interactions, on MMSE scores in a healthy sample.
METHODS
Demographic data and scores on the MMSE of 1,553 healthy individuals were analyzed. The sample was grouped according to age and education.
RESULTS
The sample was composed of 963 females (62%), mean age ±SD was 49.6±20.7yrs (range 20 to 92 yrs). The mean years of education ±SD was 8.9±5.5yrs (range 0 to 28 yrs). The mean score ±SD on the MMSE was 27.3±2.7(range 15 to 30). A significant effect of the interaction between education and sex (p=0.011), and also between education and age was observed (p=0.003). An independent effect of education (p<0.001) and age (p<0.001) was found. Participants from the higher educated group presented higher MMSE scores than the other groups. Younger adults presented higher MMSE scores than the other age groups.
CONCLUSIONS
We observed an effect of education and age on MMSE scores. Younger individuals and higher educated participants presented higher scores.
未标注
在更好的测量方法被广泛接受使用之前，简易精神状态检查表（MMSE）将继续被采用。在此背景下，了解其在巴西人群中的分布特征和决定因素尤为重要。本研究旨在基于多变量分析，评估年龄、教育水平和性别及其相互作用对健康样本中MMSE分数的独立影响。
方法
分析了1553名健康个体的人口统计学数据和MMSE分数。样本按年龄和教育程度分组。
结果
样本包括963名女性（62%），平均年龄±标准差为49.6±20.7岁（范围20至92岁）。平均受教育年限±标准差为8.9±5.5年（范围0至28年）。MMSE的平均分数±标准差为27.3±2.7（范围15至30）。观察到教育与性别之间的相互作用有显著影响（p = 0.011），教育与年龄之间的相互作用也有显著影响（p = 0.003）。发现教育（p < 0.001）和年龄（p < 0.001）有独立影响。受过高等教育组的参与者MMSE分数高于其他组。年轻成年人的MMSE分数高于其他年龄组。
结论
我们观察到教育和年龄对MMSE分数有影响。年轻人和受过高等教育的参与者分数更高。
