[Prevalence of overweight and obesity, and associated factors in adolescents, at the central west area of the state São Paulo (SP, Brazil)].
The aim of the study was to evaluate the relationship between the Body Mass Index (BMI) and the DMFT index, in 207 adolescents aged 12 years old, from 8 public and private schools of the central west area of São Paulo State. From a sample of 380 12 year-old adolescents, both genders, 207 were examined. We used the index DMFT, CBI for weight, measured of stature and applied a questionnaire about alimentary habits, characteristic anthropometrics and physical activity. Regarding body weight, 55.93% was normal, 35.59% had low weight, and 8.47% were pre-obese in private schools. In the public schools, 52.03% had normal weight, 41.22% had low weight, 4.73% were pre-obese and 2.03% were obese, without significant difference (p=0.45). The DMFT of public schools was 2.16, compared to 0.23 in private schools (p<0.05), with 39.2% of caries-free individuals in public schools and 88.1% in private schools. There was no correlation between the increase in BMI and the increase in DMFT. There was negative correlation between socioeconomic conditions and dental caries. It was concluded that, even though the pre-obese and obese groups presented a higher frequency of food ingestion, obesity was not correlated with the increase in dental caries. However, the socioeconomic conditions were determinant for this occurrence.
