Ítem Are maximum bite forces of subjects 7 to 17 years of age related to malocclusion?(Allen Press Inc., 2016-05-01) Roldán, S.I.; Restrepo, L.G.; Isaza, J.F.; Vélez, L.G.; Buschang, P.H.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)Objective: To determine the effects of occlusion on maximum bite force of growing subjects. Materials and Methods: Incisor and first molar bite force of children and adolescents was evaluated. Four cohorts were measured annually for 3 years, starting at approximately 7, 9, 12, and 15 years of age, respectively. The initial sample included 182 females and 198 males; there were 130 subjects with normal occlusion, 111 with Class I malocclusion, and 139 with Class II malocclusion. Multilevel analyses were performed to model the growth changes and compare groups. Results: Maximum bite force increased significantly (P < .05) over time. Incisal forces peaked at 14.3 and 15.3 years of age for females and males, respectively. Maximum molar bite force peaked at 16 years for both males and females. Subjects with normal occlusion had significantly higher bite force than subjects with malocclusion. Maximum molar bite force exhibited a significant testing effect, with forces increasing 2.6 kg each year that the tests were repeated. Conclusions: Malocclusion has a detrimental effect on bite force. Changes in maximum bite force are also due to age, sex, and repeated testing.Ítem Are maximum bite forces of subjects 7 to 17 years of age related to malocclusion?(Allen Press Inc., 2016-05-01) Roldán, S.I.; Restrepo, L.G.; Isaza, J.F.; Vélez, L.G.; Buschang, P.H.; Universidad EAFIT.

Determinantes de la demanda de ubicación residencial para el 2012(Universidad EAFIT, 2016) Ibarbo Marín, Juliana; González Gil, María Paulina; Cardona Sosa, Lina Marcela; Morales Zurita, LeonardoÍtem La representación social del cuerpo según la edad y el género(Universidad EAFIT, 2019) Villada Díez, Viviana; Orejuela Gómez, Johnny JavierObjective: Identify the social representation of the body according to the age and gender of a group of people from the city of Medellín. Methods: Qualitative research with a descriptive approach and a cross-section. A case study based on semi-structured interviews to 8 people, men and women, with ages between 18 and 64 years old, of Colombian nationality who have lived all or most of their lives in the city of Medellín. Results: The data obtained allowed to identify that the subjects, independently of their age and gender, have knowledge about a repertoire of common topics that have gained great relevance in the last decades where the cult of the body has been promoted. It was also possible to see how this information about the body has repercussions and is reflected in the field of representation that is built around it; therefore, the subjects not only describe the body as a set of elements that are connected to each other but also emphasize the importance of its care and give greater relevance to its functionality and healthy state than to its aesthetic character. In the same way, the information and the field of representation that the subjects have over the body influence their attitudes towards it, where it is not only reflected in the habits that they adopt in relation to it, but also in the judgments that are emitted over the body of others. Conclusion: Although the subjects have common elements in the three dimensions that compose the social representation, they also appear in these differences according to their age and gender. These variations are linked to topics that may be more relevant for one age range than for another, or for one gender than for another. As a result, the variations tend to be more in relation to the additional topics they mention than to opposite positions on the same topic.
