To evaluate whether changes in starch intake (in terms of amount and food sources) were associated with increments in dental caries among adults.
This is an 11-year longitudinal study (2000-2011) with duplicate assessments for all variables. A 128-item FFQ was used to estimate intake of starch (g/d) and six starch-rich food groups (potatoes, potato products, roots and tubers, pasta, wholegrains and legumes). Dental caries was assessed through clinical examinations and summarised using the number of decayed, missing and filled teeth (DMFT score). The relationship between quintiles of starch intake and DMFT score was tested in linear hybrid models adjusting for confounders.
Northern and Southern regions of Finland.
922 adults, aged 30-88 years.
Mean starch intake was 127·6 (sd: 47·8) g/d at baseline and 120·7 (55·8) g/d at follow-up. Mean DMFT score was 21·7 (6·4) and 22·4 (6·2) at baseline and follow-up. Starch intake was inversely associated with DMFT score cross-sectionally (rate ratio for highest . lowest quintile of intake: -2·73, 95 % CI -4·64, -0·82) but not longitudinally (0·32, 95 % CI -0·12, 0·76). By food sources, the intakes of pasta (-2·77, 95 % CI -4·21, -1·32) and wholegrains (-1·91, 95 % CI -3·38, -0·45) were negatively associated with DMFT score cross-sectionally but not longitudinally (0·03, 95 % CI -0·33, 0·39 and -0·10, 95 % CI -0·44, 0·24, respectively).
Changes in the amount and sources of starch intake were not associated with changes in dental caries. Further studies should be conducted in different settings and age groups while focusing on starch digestibility and specific sources of starch.
评估淀粉摄入量的变化（在量和食物来源方面）是否与成年人龋齿增加有关。
这是一项为期11年的纵向研究（2000 - 2011年），对所有变量进行重复评估。使用一份包含128个条目的食物频率问卷来估计淀粉摄入量（克/天）以及六个富含淀粉的食物组（土豆、土豆制品、块根和块茎、面食、全谷物和豆类）。通过临床检查评估龋齿情况，并使用龋失补牙数（DMFT评分）进行汇总。在调整混杂因素的线性混合模型中测试淀粉摄入量五分位数与DMFT评分之间的关系。
芬兰北部和南部地区。
922名年龄在30 - 88岁之间的成年人。
基线时淀粉平均摄入量为127.6（标准差：47.8）克/天，随访时为120.7（55.8）克/天。基线和随访时DMFT评分的平均值分别为21.7（6.4）和22.4（6.2）。淀粉摄入量与DMFT评分在横断面分析中呈负相关（摄入量最高五分位数与最低五分位数的率比：-2.73，95%置信区间 -4.64，-0.82），但在纵向分析中无相关性（0.32，95%置信区间 -0.12，0.76）。按食物来源分析，面食（-2.77，95%置信区间 -4.21，-1.32）和全谷物（-1.91，95%置信区间 -3.38，-0.45）的摄入量与DMFT评分在横断面分析中呈负相关，但在纵向分析中无相关性（分别为0.03，95%置信区间 -0.33，0.39和 -0.10，95%置信区间 -0.44，0.24）。
淀粉摄入量的量和来源变化与龋齿变化无关。应在不同环境和年龄组中开展进一步研究，同时关注淀粉消化率和淀粉的特定来源。
