AimTo evaluate the association between baseline starch intake (amount and sources) and changes in periodontal status over 11 years in adults.MethodsAdults aged 30–82 years, who participated in the Finnish Health 2000 survey and were re‐examined in 2004/2005 and/or 2011 were included in the study. The consumption of total starch and six relevant food groups (potatoes, fried potatoes, roots and tubers, pasta, wholegrains and legumes) over the past year was determined at baseline with a validated food frequency questionnaire. The number of teeth with periodontal pocketing ≥ 4 mm (NTPP) was recorded during clinical examinations in 2000, 2004/2005 and 2011. The association between baseline starch intake and the 11‐year change in the NTPP was tested in mixed‐effects negative binomial regression models, adjusting for covariates.ResultsA total of 1369 adults were included in the analysis. The mean NTPP was 4.1 ± 5.6, 6.3 ± 5.6, and 4.8 ± 5.9 in waves 1, 2 and 3, respectively. Baseline starch intake (in g/day or % energy intake) was not associated with changes in the NTPP after adjustment for covariates. In analysis by food groups, the baseline intake of wholegrains was negatively associated with the NTPP at baseline.ConclusionThis study found no evidence of an association between baseline starch intake and changes in periodontal status. Baseline intake of wholegrains was associated with better periodontal status at baseline.

淀粉摄入量与牙周状况有关吗？芬兰成年人 11 年纵向分析


目的评估成人基线淀粉摄入量（数量和来源）与 11 年内牙周状况变化之间的关联。方法参加芬兰健康 2000 年调查并于 2004/2005 年和/或 2011 年被纳入研究。过去一年的总淀粉和六种相关食物组（土豆、炸土豆、块根和块茎、面食、全麦和豆类）的消耗量是通过经过验证的食物频率调查问卷确定的基线。在 2000 年、2004/2005 年和 2011 年的临床检查中记录了牙周袋≥ 4 毫米 (NTPP) 的牙齿数量。基线淀粉摄入量与 NTPP 11 年变化之间的关联通过混合效应负二项式进行了测试回归模型，调整协变量。结果 分析中总共包括 1369 名成年人。第 1、2 和 3 波中的平均 NTPP 分别为 4.1 ± 5.6、6.3 ± 5.6 和 4.8 ± 5.9。调整协变量后，基线淀粉摄入量（以克/天或能量摄入百分比计）与 NTPP 的变化无关。在按食物组进行的分析中，全谷物的基线摄入量与基线的 NTPP 呈负相关。结论本研究没有发现基线淀粉摄入量与牙周状态变化之间存在关联的证据。全谷物的基线摄入量与基线时更好的牙周状态相关。
