Abstract

近年,妊娠期の歯周病が低体重児出産(2,500g未満での出産)の危険因子として注目されている.徳島県では,平成17年度8020運動特別推進事業の一環として妊婦歯科健診が実施された.本研究では,妊婦歯科健診で得られた739名の健診結果ならびにアンケート結果より,妊婦の口腔保健の現状を調査した.その結果,口腔内に不満や不自由を覚える者は454名(61.4%),ブラッシング時に出血を認める者は380名(51.4%),未処置歯または楔状欠損歯を有する者は406名(54.9%),4mm以上の歯周ポケットを有する者は301名(40.7%)と高い値が示された.一方,定期的に歯科医院を受診している者は136名(18.4%)と低い値であった.さらに,産後に出生児の出生時体重を郵送法にて調査し,回答が得られた227名について,口腔保健の現状と低体重児出産との関連性について検討を行った.ロジスティック回帰分析の結果,喫煙習慣(OR 5.96, 95%CI 1.16-30.53, p=0.03)および4mm以上の歯周ポケットを有する状態(OR 3.34, 95%CI 1.18-9.42,p=0.02)が低体重児出産に有意に関連していた.今後,妊婦に対しては,歯科医院の定期受診率を上げることに加え,さらに充実した禁煙支援を含めた歯周状態の管理が必要であると考えられる.

Recent studies have suggested that periodontal diseases in pregnant women may be a significant risk factor for low-birth-weight deliveries (less than 2,500g). The aim of this study was to investigate the relationships between the oral health condition, health behavior of pregnant women, and low-birth-weight outcome. We performed oral examinations and conducted a survey of pregnant women to investigate their oral health status and behavior in Tokushima Prefecture. Among 739 pregnant women that received oral examinations, 454 (61.4%) reported complaints and inconvenience related to their oral cavities, 380 women (51.4%) reported gingival bleeding on brushing, while 406 women (54.9%) had teeth which needed treatment. Three hundred and one women (40.7%) harbored periodontal pockets with a depth &ge;4mm, and were assigned a Community Periodontal Index (CPI) code of 3 or 4. On the other hand, there were only 136 women (18.4%) who received regular dental checkups. The percentage of pregnant women with a CPI of 3 or 4 was higher than that of women in the same age group based on the Comprehensive Guide to the Survey of Dental Diseases (2005). The percentage of subjects with a CPI of 3 or 4 among pregnant women with a smoking habit was higher than in a group of non-smoking pregnant women (p<0.05). All pregnant women with a smoking habit had a CPI&ge;1. In addition, we examined the relationship between the oral health status of the pregnant women and a low-birth-weight outcome. Stepwise logistic regression analysis of the 227 pregnant women who signed the informed consent document for this study showed that a smoking habit (OR 5.96, 95% CI 1.16-30.53, p=0.03) and periodontal pocket depth &ge;4mm (OR 3.34, 95% CI 1.18-9.42, p=0.02) were significantly associated with low-birth-weight deliveries. In conclusion, efforts should be made to motivate pregnant women to undergo regular dental checkups for periodontal disease prevention and quit smoking.
