The human voice is produced by a neurophysiological mechanism which adds to itself individual and emotional aspects. When there is any deviation which prevents voice production in a healthy way, it can develop vocal symptoms and may result in dysphonia that can affect the quality of the individual´slife. Some factors increase the probability of dysphonia and it is called vocal risk factors. Exposure to these factors can relate to the genesis and/or maintenance of the problem. Some factors related to emotion can promote changes in the voice production process and interfere in a negative way for healthy production, being considered risk factors as well. The objective of this study was to determine which risk factors have promoted greater influence on the development of a vocal problem. The study is a case-control. Participants were divided into two groups from the cutoff of Vocal ScaleSymptoms. The case group (GCA) was composed of participants with vocal problems and had the Vocal ScaleSymptoms up 16 points, and the control group (GCO), with participants without voice problems, with less than or equal to 16. The data collection was held at the Integrated Laboratory of Voice of the Federal University of Paraíba (UFPB) and at the Dermatology clinic of the University Hospital LauroWanderley / UFPB. For data collection, the instruments were used: Vocal ScaleSymptoms, Vocal Screening Protocol and State Trait Anxiety Inventory (STAI). Data were analyzed using descriptive statistics and logistic regression to determine which vocal and emotional risk factors influenced the outcome of the vocal problem. All analyzes were done in the statistical program R. It was found that the average age for the GCA was 40.37 years old and 37.43 for COG. Most participants were female both GCA (83.6%) and for GCO (64.9%). The most frequent audiological diagnostic GCA was lesion in the membranous portion of the vocal fold (52.2%). The total score of Vocal ScaleSymptomsGCA was 52.2 and the GCO was 7.94. The GCA had a mean number of risk factors to 11.74 and 9.37 to the CGO. Most of the GCA presented High Anxiety rating (58.2%) and GCO predominated classification Low anxiety (54.4%). The logistic regression model showed that the most influential variables for a vocal problem is effort to speak (p <0.001), age (p = 0.006), excessive vocal demand (p = 0.03) and constant cough (p = 0.006 ), and time long service (p <0.001), the latter being considered as a protective factor for vocal problem. The conclusion is that older people, who make effort to speak, present constant and excessive vocal demand cough have a higher chance of developing a vocal problem, on the other hand the ones who have a long time of service has less chance. Regarding to anxiety, most GCA participants have high anxiety and GCO have low anxiety.
