Abstract:

Objective

To compare and analyze the distribution differences of oral health behaviors of Zhuang and Han ethnic children aged at 3-5 years in Baise, Guangxi, and to explore whether children′s health behaviors are affected by ethnic and socioeconomic risk factors.

Methods

In September 2016, three kindergartens were randomly selected after the numbering of 23 kindergartens in Baise, Guangxi. Zhuang and Han ethnic children aged at 3-5 years (196 each nation) were randomly selected from three kindergartens. The single factor analysis was used to analyze oral health behaviors of children. Multiple logistic regression was used to explore whether ethnic factor affected oral health behaviors.

Results

The proportion of Zhuang ethnic children (41.84%) who consumed sweet fruit juice more than once a day was significantly higher than that of Han children (3.06%, χ2 = 84.64, P<0.001) . The proportion of Zhuang children (74.00%) who always or intermittently took desserts and sweet drinks before bedtime was statistically higher than that of Han children (28.06%, χ2 = 82.69, P<0.001) . The proportion of Zhuang ethnic children who started brushing teeth before the age of 3 (65.31%) was significantly higher than that of Han ethnic (25.00%, χ2 = 64.29, P<0.001) . The proportion of Zhuang ethnic children who brushed their teeth more than twice a day (66.33%) was significantly higher than that of Han Chinese (19.39%, χ2 = 88.17, P<0.001) . The proportion of Zhuang ethnic parents who assisted their children in cleaning their teeth daily was significantly higher (65.31%) than that of Han ethnic parents (23.98%, χ2 = 67.73, P<0.001) . The results of the multifactorial analysis showed that Zhuang ethnic children had 9.52 times higher risk of daily consumption of juice (OR = 9.52, 95% CI = 3.00-30.19) and 3.94 times higher risk of taking desserts/ sweet drinks before bedtime than Han ethnic children (OR = 3.94, 95% CI = 2.32-6.68) . Besides, Zhuang ethnic children started cleaning their teeth at an earlier age (OR = 3.29, 95% CI = 1.92-5.63) and more frequently each day (OR = 4.97, 95% CI = 3.01-8.22) than Han children. Additionally, Zhuang ethnic parents assisted their children to clean their teeth more frequently than Han parents (OR = 2.88, 95% CI = 1.74-4.76) . Furthermore, sociological factors were also considerably associated with oral health behaviors of children.

Conclusion

Ethnic and socioeconomic factors are important in influencing the oral health behaviors of Zhuang and Han ethnic children.
