To evaluate if poor oral status was associated with percentage body fat in a representative sample of south Brazilian community-dwelling elderly.
Evidence suggests that elders with extensive tooth loss and edentulism present with compromised chewing function, which results in dietary changes. However, few studies have assessed whether poor oral status is associated with percentage body fat in community-dwelling elderly.
A random sample of 471 south Brazilians =>60 years of age was evaluated. Measurements included a questionnaire to assess socio-demographic, behavioural, general, and oral health data. Percentage body fat was measured with a Tanita TBF 612 digital scale, which measures foot-to-foot bioelectrical impedance; and oral status assessment, by means of oral examinations assessing the number of teeth and use of dental prostheses. Correlates of risk of inadequate percentage body fat were assessed by means of multinomial logistic regression.
Edentulous participants were more likely to be underfat [OR: 3.11 (1.27-7.61)] or overfat/obese [OR: 1.82 (1.05-3.16)].
The present study shows that edentulous older people had higher odds for inadequate percentage body fat. The maintenance of teeth had a crucial role in increasing the chance of having an adequate body fat percentage in the study population.
评估在南巴西南部的一个有代表性的社区居住的老年人样本中，口腔状况不佳是否与体脂肪百分比有关。
有证据表明，大量缺牙和无牙的老年人咀嚼功能受损，导致饮食改变。然而，很少有研究评估口腔状况不佳是否与社区居住的老年人的体脂肪百分比有关。
评估了南巴西南部的一个随机样本 471 名年龄在 60 岁以上的人。测量包括一个问卷，以评估社会人口统计学、行为、一般和口腔健康数据。体脂肪百分比采用 Tanita TBF 612 数字秤测量，该秤通过测量足底到足底的生物电阻抗来测量；口腔状况评估通过口腔检查评估牙齿数量和使用牙科假体来进行。通过多项逻辑回归评估了体脂肪百分比不足的风险的相关因素。
无牙参与者更有可能处于消瘦状态[OR：3.11（1.27-7.61）]或超重/肥胖状态[OR：1.82（1.05-3.16）]。
本研究表明，无牙的老年人更有可能出现体脂肪百分比不足。在研究人群中，保持牙齿对增加体脂肪百分比适当的机会具有关键作用。
