Abstract

OBJECTIVE

To assess whether short-term changes in income (IC) in adulthood were associated with self-rated oral health (SROH) and chewing difficulties (CD).

METHODS

Secondary analysis of a longitudinal study in Florianópolis, Southern Brazil (EpiFloripa); a total of 1720 adults participated in 2009 and 1223 in 2012. Logistic regression analysed the variation of SROH and CD according to short-term changes in income (IC) groups ('high income-stable', 'increased income', 'decreased income' and 'low income-stable') and adjusted for covariates (age, sex, marital status, skin colour, self-reported number of teeth and education).

RESULTS

After adjusting for covariates, participants in the 'decreased income' were more likely to have poor SROH and CD than those at the 'high income-stable' group (OR: 1.78, 95% CI: 1.23, 2.58; OR: 2.76, 95% CI: 1.61, 4.74, respectively). Significant differences were also found between the 'low income-stable' and 'high income-stable' groups, but these differences were explained when adjusted for potential confounders. There were no significant differences in SROH and CD between the 'increased income' and the 'high income-stable' groups.

CONCLUSIONS

Overall, SROH and CD were adversely influenced by negative changes in income during adulthood in a short period of 3 years.

摘要

目的

评估成年期收入的短期变化（IC）是否与自评口腔健康（SROH）和咀嚼困难（CD）相关。

方法

对巴西南部弗洛里亚诺波利斯的一项纵向研究（EpiFloripa）进行二次分析；2009年共有1720名成年人参与，2012年有1223名。逻辑回归分析了根据收入（IC）组的短期变化（“高收入稳定”、“收入增加”、“收入减少”和“低收入稳定”）划分的SROH和CD的变化，并对协变量（年龄、性别、婚姻状况、肤色、自我报告的牙齿数量和教育程度）进行了调整。

结果

在对协变量进行调整后，“收入减少”组的参与者比“高收入稳定”组的参与者更有可能出现较差的SROH和CD（OR：1.78，95%CI：1.23，2.58；OR：2.76，95%CI：1.61，4.74）。在“低收入稳定”组和“高收入稳定”组之间也发现了显著差异，但在对潜在混杂因素进行调整后，这些差异得到了解释。“收入增加”组和“高收入稳定”组在SROH和CD方面没有显著差异。
