Questionnaire on body awareness of postural habits in young people: construction and validation

Young people's low back pain and awareness of postural habits: A cross-sectional study

BACKGROUND

Young people tend to spend most of their time in activities involving inappropriate positions, which can promote musculoskeletal alterations and disorders.

OBJECTIVE

To investigate the prevalence of low back pain (LBP) in young people and analyse its associations with daily postural habits.

METHODS

Cross-sectional and retrospective study evaluating 679 Brazilian young people (15 to 18 years old), using questionnaires about LBP and awareness of postural habits. The prevalence values were calculated for the present moment, the last three months and throughout life. The Mann-Whitney U test and the Chi-square test were applied.

RESULTS

The prevalence of LBP at the present moment was 27.2%, 57.7% over the last three months and 73.9% throughout life. Boys and girls presented significantly different values, a larger number of girls manifesting pain for the three moments. The associated postural habits were: turning the body, reduction of lumbar lordosis when seated, not placing the feet on the floor, crossing the legs when sitting in the classroom and at home, sitting or lying in an inappropriate position, and distributing the body asymmetrically on the legs when standing.

CONCLUSIONS

Young people from 15 to 18 years of age show a high prevalence of low back pain. Inadequate postural habits adopted during everyday activities are associated with this complaint. These findings could contribute to the implementation of prevention and rehabilitation strategies.

DEVELOPMENT OF THE POSTURAL HABITS AND AWARENESS SCALE (PHAS): A RELIABILITY AND VALIDITY STUDY

Objectives. The aim of this study was to develop a scale that assesses postural awareness and habits, as well as to establish the validity and reliability thereof. Methods. The 19-item Postural Habits and Awareness Scale was developed. The scale has a score range of 0-95, with a higher score indicating good posture and awareness. 278 healthy adults with an age range of 18-65 years were included in the study. The sociodemographic form, Short Form 36 Health Survey (SF-36), and Body Awareness Questionnaire (BAQ) were used to test the validity and reliability of this newly developed scale. Results. From factor analyses, it was observed that the items clustered in 4 factors, which explained 55.99% of the variance. The Cronbach's α for each factor of the scale varied between 0.619 and 0.832. A high correlation was observed regarding test-retest reliability of the scale (r: 0.905). Conclusion. This newly developed self-reported scale allows for the comprehensive determination of both postural habits and awareness together. The PHAS is a valid and reliable scale that can be used by professionals who are interested in posture.
