The study examined energy intake in relation to dental caries and periodontal disease in 11-yr-old rural and urban black children in low fluoride areas of KwaZulu and Namibia (0.15 ppm F) and one higher fluoride area of Namibia (1.56 ppm F). Twenty-four hour dietary recalls were conducted by trained interviewers and daily energy intake estimated using the MRC dietary analysis programme. DMFS was recorded according to WHO criteria: periodontal disease was measured using CPITN and SAS was used for statistical analysis. The prevalence of dental caries and periodontal disease (using CPITN), were compared within three energy groupings; < or = 850 kcal/day; > 850, < 1400 kcal/day and > or = 1400 kcal/day. The rural low fluoride Namibian children had the lowest mean energy intake (616 kcal/day), which also was the grouping with highest healthy periodontal prevalence (65%). The urban groups had higher energy intakes than the rural communities. Statistically significant effects on caries prevalence were seen for country and fluoride grouping; for periodontal disease, significant effects were noted for country, fluoride group and environment. Energy intake had no statistically significant effect, so this is not a risk marker for the disease.
该研究调查了夸祖鲁和纳米比亚低氟地区（氟含量0.15 ppm）以及纳米比亚一个高氟地区（氟含量1.56 ppm）11岁城乡黑人儿童的能量摄入与龋齿和牙周疾病的关系。由经过培训的访谈人员进行24小时饮食回顾，并使用医学研究委员会饮食分析程序估算每日能量摄入量。根据世界卫生组织标准记录龋失补牙面数（DMFS）；使用社区牙周指数（CPITN）测量牙周疾病，并使用SAS进行统计分析。在三个能量分组范围内比较了龋齿和牙周疾病（使用CPITN）的患病率；每天≤850千卡；＞850千卡且＜1400千卡；以及≥1400千卡。纳米比亚农村低氟地区儿童的平均能量摄入量最低（每天616千卡），该分组的牙周健康患病率也是最高的（65%）。城市组的能量摄入量高于农村社区。对于国家和氟分组，观察到对龋齿患病率有统计学显著影响；对于牙周疾病，观察到国家、氟分组和环境有显著影响。能量摄入没有统计学显著影响，因此这不是该疾病的风险指标。
