Boys and girls as health-promoting actors—determinants of oral health-related lifestyle among 11- to 12-year-old schoolchildren

The aim of this study was to explore childand parent-related determinants of oral health-related lifestyle and presence of active initial caries lesions among a group of Finnish schoolchildren. The original study population consisted of 5th and 6th graders and their parents in Pori (n = 1691) and in Rauma (n = 821), Finland. Data concerning oral health-related knowledge, attitudes, beliefs and behaviors were gathered with questionnaires. In Pori, all children included in the sample were invited to participate in a dental screening performed to find suitable candidates for a randomized clinical trial. For screening, the presence or absence of active initial caries lesions was used. A group of behaviors comprising frequencies of toothbrushing with fluoride toothpaste, consumption of sweets and soft drinks and use of xylitol products described oral health-related lifestyle. More girls (36%) than boys (21%) had a favorable lifestyle lifestyle (i.e. at least three of the four recommended behaviors). Parents' healthy lifestyle was indicative of a healthy lifestyle among their children. Among boys, the effect of parents' lifestyle was slightly stronger than among girls. Children whose behaviors were favorable were more likely to have good knowledge about oral health-related items than did those whose behaviors were unfavorable. In addition, parents whose children belonged to the favorable lifestyle group had better oral health-related knowledge than those parents whose children belonged to the moderate or poor lifestyle groups. Parent's poor self-assessed dental health and poor oral health-related lifestyle were found to be indicators for dental decay among their children. Those children who did not know if their mother and/or father had dental decay were more likely to have at least one active initial caries lesion than those who knew whether their parents had tooth decay. Poor belief and negative attitudes were associated with the presence of caries lesions. Both children's and their parents' oral health-related knowledge is associated with children's oral health-related lifestyle. Parents' favorable lifestyle and good dental health seem to have a favorable impact on their children's dental health. In adopting healthy oral health-related lifestyle, both the mother and the father seem to play an important role.
