The relationship between body mass index (BMI) and dental caries consists of multiple contributing factors. There have been no studies documented in the literature in this part of rural India assessing the prevalence of dental caries in relation to BMI. Hence, an attempt was made to study dental caries in relation to BMI and anthropometric measurements.
The aims were to study dental caries experience in relation to BMI and anthropometric measurements of rural children in Nellore district.
A descriptive cross-sectional study was carried out in Nellore city.
A total of 1500 6- and 12-year-old children were examined. Dental caries was examined using the WHO dentition status criteria (1997) and 1-day diet chart was collected from each child followed by collection of anthropometric data.
Statistical analysis was performed using Chi-square test, Fisher's exact test, and Spearman's correlation test.
In the present study, out of all the participants, 59.2% of low weight children, 41.3% of normal weight children, and 25.7% of overweight-obese children were having dental caries. Dental caries was more among low weight children compared to normal weight and overweight-obese children and was statistically significant.
All the anthropometric measurements were positively correlated with dental caries except height for age and BMI for age. There was an inverse graded association between the height for age and BMI for age with dental caries in 6- and 12-year-old children.
体重指数（BMI）与龋齿之间的关系由多种因素构成。在印度农村的这一地区，尚无文献记载评估与BMI相关的龋齿患病率的研究。因此，我们尝试研究与BMI及人体测量学指标相关的龋齿情况。
目的是研究内洛尔地区农村儿童的龋齿患病情况与BMI及人体测量学指标之间的关系。
在维杰亚瓦达市开展了一项描述性横断面研究。
共检查了1500名6岁和12岁的儿童。使用世界卫生组织（WHO）牙列状况标准（1997年）检查龋齿情况，并收集每个儿童的一日饮食图表，随后收集人体测量数据。
采用卡方检验、费舍尔精确检验和斯皮尔曼相关性检验进行统计分析。
在本研究中，所有参与者中，体重过低儿童中有59.2%、正常体重儿童中有41.3%、超重/肥胖儿童中有25.7%患有龋齿。与正常体重和超重/肥胖儿童相比，体重过低儿童的龋齿患病率更高，且具有统计学意义。
除年龄别身高和年龄别BMI外，所有人体测量指标均与龋齿呈正相关。在6岁和12岁儿童中，年龄别身高和年龄别BMI与龋齿呈反向分级关联。
