Down syndrome (DS) is a genetic disorder in which there is an increased risk
of developing clinical comorbidities that require regular attention: health problems, alterations in
maxillomandibular development, chewing and swallowing problems, as well as dietary habits that
may influence diet and nutritional status. This study will analyze the frequency of occurrence of
these factors with increasing age in this population. Methods: A descriptive cross-sectional study was
conducted with 18 participants aged 30–45 years. The condition of orofacial structures, chewing and
swallowing function and oral and eating habits were assessed to observe the frequency of occurrence
of these problems with increasing age. Results: A high frequency of digestive problems was observed.
There was also a presence of problems in the introduction of new tastes and consistencies. In addition,
unilateral chewing was reported in 100% of the participants, severe anatomical dysfunction of the
mandible/maxilla and high hypotonicity reflected in tongue movements. Conclusions: it is necessary
to educate, through specific intervention protocols, the younger generations with DS, as well as their
environment, as harmful habits are developed in childhood and consolidated throughout life
