Description of intervention(s) / exposure
The Brazilian population is aging at an increasing pace, especially in recent decades. This increase in life expectancy is due to several factors that together has provided an improvement in living conditions. The result is a significant change in the age of the population pyramid distribution, with a reduction in birth rate and aging population. The feed can affect the development and cooperate in the progression of diseases of the oral cavity, while these diseases can result in tooth loss, which in turn, within this cycle, may influence the choice of food. Cross-sectional study with 54 subjects (grandparent-elderly), of both sexes, each with his child (54 adult) and grandchild (54 child). In this study was measured the association between oral condition and nutritional status. The oral health status was determined using the codes and criteria established by the World Health Organization (1997) and assessed by a dmft index (decayed, missing or filled primary teeth) for children, DMFT index (permanent teeth decayed, missing and filled) for adults and the number of functional units present in the oral cavity was used for grandparents. The classification of nutritional status was performed according to criteria adopted by World Health Organization (WHO, 2008) for adults and the elderly and, for children was used the criteria recommended by WHO, 2006, 2007, based on Body Mass Index (BMI). The approximate duration of assessment in each participant was of the 2 hours and on one occasion only.

Assessment of oral health status
Oral health status was assessed by a single calibrated operator under natural light. The dmft index (decayed, missing or filled primary teeth) for children, DMFT index (permanent teeth decayed, missing and filled) for adults and the number of functional units present in the oral cavity was used for grandparents, were determined using the codes and criteria established by the World Health Organization (1999). The oral health status was classified into satisfactory and unsatisfactory, according to age, adapted indexes, established for oral health by the WHO (1997) and SB-Brazil Project (2004). For ages between five and under twelve years was considered satisfactory when dmft/DMFT equal zero and unsatisfactory when dmft/DMFTmore than zero. For ages between twenty years and less than or equal to sixty-five years was considered satisfactory when DMFT less or equal to 13 and unsatisfactory when DMFT more than 13. For individuals with more than to sixty-five years was considered satisfactory when have 10-14 functional units dental and unsatisfactory when less or equal to 10 functional units dental. Habits related to oral health care were investigated through an interview with questions that relate to the following variables: frequency of consumption of foods with sugar and visit to the dentist.

Assessment of nutritional status
For the evaluation of body weight was used a portable electronic scale (Marte MS-160 with platform, Sao Paulo, Sao Paulo, Brazil), with a sensibility of 50 g and maximum capacity of 160 kg. To check this, was following this procedures: light clothes and without shoes, the individual remained standing on the center of scale platform, with your weight evenly distributed on both feet, with arms side of the body. Weight was recorded in kilograms (kg) and grams (g) (WHO, 1995). To check the height was used a anthropometer (Alturaexata, Belo Horizonte, Minas Gerais, Brazil), with a precision of 0.1 cm, as recommended by WHO (1995). With the head in the line of sight perpendicular to the body, ie, parallel to the ground, the individual was instructed to inhale deeply, and in apnea was taken the measure of stature. The reference was the measure the highest point of the head with sufficient pressure to compress the hair. There were two measures, by calculating the arithmetic mean of these (WHO, 1995). The classification of nutritional status was performed according to criteria adopted by World Health Organization (WHO, 2008) for adults and the elderly and, for children was used the criteria recommended by WHO, 2006, 2007, based on Body Mass Index (BMI). The triceps skinfold (TSF) was collected with the skinfold compass (Lange Skinfold Caliper, Santa Cruz, California, USA) in the right hemibody, according to the methodology of the World Health Organization (1995). For TSF were used the reference values of Frisancho (1981). The waist circumference (WC) was collected using the procedure described by Callaway et al. (1991). Were used a flexible tape measure with an precision of 1 mm. The values of waist circumference for children and adolescents are presented as percentiles, with the cut off points by age and sex according to Taylor et al. (2000). The classification of central obesity in adults and older met the criteria suggested by WHO (2000). To measurement the circumference of the calf was used the methodology of the World Health Organization (1995). Was used a tape measure graduated, flexible, inelastic, with an accuracy of 0.1 cm. Habits eating were investigated through an interview.

Socio-economic status
The sample was classified according to a criterion adapted from the Brazil economic classification, developed by the Associacao Brasileira de Empresas de Pesquisa (2003), that classifies the population in economic classes A, B, C, D and E, as determined by their spending power and level of schooling of the head of the family.
