Functional consequences and health-care seeking behaviour for recurrent non-specific low back pain in Zimbabwean adolescents: a cross-sectional study

Questionnaires that assess disability in children and adolescents with low back pain adhere to the concepts of the International classification of functioning, disability and health (ICF), but lack validity for this population: a systematic review

PURPOSE

We aimed to identify Patient-Reported Outcome Measures (PROMs) that assess disability in children and adolescents with low back pain (LBP), analyzing their adherence to the International Classification of Functioning, Disability and Health (ICF) biopsychosocial model; and to describe the measurement properties of these PROMs.

METHODS

We searched Pubmed, Embase and CINAHL databases. The review included searches up to March 2022. Meaningful concepts of the PROMs were linked to ICF domains, and we manually searched for the measurement properties of each included PROM.

RESULTS

We included 23 studies, of which eight PROMs were analyzed. We retrieved 182 concepts in total. Activities was the domain with the highest number of linked concepts, whereas personal factors had no linked concepts. The modified Hannover Functional Ability Questionnaire (mHFAQ) and the Micheli Functional Scale (MFS) had measurement properties tested in children and adolescents, but had no information about construct validity.

CONCLUSION

Although most of the identified PROMs had broad coverage of their concepts in the ICF, only two PROMs had measurement properties tested in the population of interest in this review, in which the mHFAQ presented wide coverage in relation to the ICF. Further studies are needed to investigate content validity of these PROMs.

Low back pain prevalence, beliefs and treatment-seeking behaviour in multi-ethnic Suriname

Objectives

The aims were to determine, for the first time, the prevalence of low back pain (LBP) in urban and rural communities and to assess back beliefs and treatment-seeking behaviour in Suriname, a multi-ethnic country in the Caribbean community.

Methods

A cross-sectional community-based survey using the Community Oriented Program for the Control of Rheumatic Diseases methodology was performed between April 2016 and July 2017. Information was collected on LBP prevalence and LBP-related treatment seeking, beliefs about LBP [Back Beliefs Questionnaire (BBQ)], level of disability (Oswestry Disability Index) and the risk of developing persistent disabling pain (Start Back Screening Tool).

Results

A total of 541 out of 2902 individuals reported current acute or chronic LBP. It was more prevalent in urban (20.2%) than in rural (13.7%) communities, especially in females and older adults (>55 years of age). Individuals from rural areas [median BBQ = 18.00 (14.00-22.00)] had significantly more negative beliefs than the urban population [median BBQ = 25.00 (19.00-31.00); P < 0.001]. Maroons displayed more negative beliefs than Creole (P = 0.040), Hindustani (P < 0.001), Javanese (P < 0.001) and mixed ethnicity (P < 0.001) groups. At least 75% of the LBP population sought care, especially from a western health-care practitioner. Seeking treatment and having a higher risk of developing persistent disabling pain was significantly associated with more disability (P < 0.001). Age ≥45 years (P < 0.001), Indigenous ethnicity (P < 0.05) and functional disability (P < 0.001) were factors influencing treatment seeking.

Conclusion

Low back pain is a prevalent health problem in the Surinamese urban community, especially in older adults and among females. Most individuals experiencing LBP visited a western health-care practitioner and had more negative beliefs compared with other communities.

Perspectives of spinal health within the school setting in a South African rural region: A qualitative study

BACKGROUND

Spinal pain is one of the leading causes of morbidity globally. There is an increase in the number of children and adolescents who experience spinal pain and the lifetime prevalence of adolescent spinal pain varies between countries. In Africa, one in two adolescents experiences spinal pain and the prevalence is increasing.

OBJECTIVE

This study reports on the knowledge and perspectives of school-attending children, adolescents, teachers, and parents/guardians regarding spinal health.

METHODS

We conducted a descriptive qualitative case study with an interpretative and phenomenological approach. Data coding, management and analysis was done using ATLAS.ti computer software.

RESULTS

Ninety-three participants (66 women and 27 men) were enrolled in the study. The barriers associated with students' spinal health were multifactorial, including low levels of physical activity, dangerous gameplay, sports risks, poor ergonomics, school bags, insufficient knowledge, and pregnancy risks. Participants proposed strategies to improve spinal health including the provision of students' lockers, advice on appropriate school bag types, embedding spinal education in the curriculum, general advocacy for spinal health, and integration of technology in teaching and learning.

CONCLUSION

There is a need for further engagement on school-based spinal health promotion programs that consider local socio-economic, educational, and cultural factors.

Prevalence of low back pain, seeking medical care, and lost time due to low back pain among manual material handling workers in the United States

Background

Low back pain (LBP) is a common and costly problem throughout the United States. To achieve a greater understanding of the occupational risk factors, the National Institute for Occupational Safety and Health (NIOSH) funded a low back health effects consortium, which performed several surveillance studies throughout the United States. This study combines data from the consortium research groups resulting in a data set with nearly 2000 workers in various regions of the country. The purpose of this paper is to examine prevalence and personal risk factors of low back health effects among these workers.

Methods

There were three common questions regarding history of low back health effects in the past 12 months including 1) have you had LBP lasting 7 days, 2) have you sought medical care for LBP, and 3) have you taken time off work due to LBP. The questionnaire included demographic questions. There were five data collections institutions or sites including NIOSH, Ohio State University, University of Wisconsin-Milwaukee, Texas A&M University, and University of Utah.

Results

The 12-month period prevalence of low back pain lasting 7 days, seeking medical care, and lost time due to LBP were 25, 14 and 10%, respectively. There were no statistically significant differences in gender, age or weight between cases and non-cases for any prevalence measure. The height of workers was significantly greater in the cases compared to non-cases for all three prevalence definitions. There were significant differences among the sites on the prevalence of seeking medical care for LBP and lost time due to LBP. The Ohio State University had significantly higher prevalence rates for seeking medical care and lost time due to LBP than University of Wisconsin, University of Utah, or Texas A&M University.

Conclusion

LBP, the least severe low back health effect studied, had the highest prevalence (25%) and lost time due to LBP, the most severe low back health effect studied, had the lowest prevalence (10%) among nearly 2000 US manual material handling workers. There was a significant site or regional influence in prevalence rates for seeking medical care and lost time due to LBP.

The burden of low back pain among undergraduate physiotherapy students at the University of Zimbabwe: a cross-sectional study

OBJECTIVE

Globally, non-specific low back pain (NSLBP) is a common cause of morbidity in all people including physiotherapy students. However, no study has investigated the problem among undergraduate physiotherapy students in Zimbabwe. This study was conducted, therefore, to provide evidence of the prevalence, clinical characteristics and consequences of recurrent NSLBP among undergraduate physiotherapy students at the University of Zimbabwe.

RESULTS

The final sample had 90 participants, giving a study response rate of 97.8%. The median age of the participants was 22 years. The lifetime prevalence of NSLBP was 56.7% (n = 51) and the mean age of onset for NSLBP was 19.7 years (SD = 1.64 years). The 12-month prevalence of recurrent NSLBP was 38.9% (n = 35). Of the 35, 20 (57.1%) experienced at least three episodes in the last 12 months. Each episode lasted for 1-7 days in most participants (n = 31, 88.6%). The mean intensity of recurrent episodes was 3.37 (SD = 1.43) measured on Visual Analogue Scale. Only 7 (20%) experienced at least one functional limitation due to recurrent NSLBP. Additionally, only 2 (5.7%) sought medical treatment for the pain. However, 6 (17.1%) had to be absent from the university secondary to recurrent NSLBP.

Content validity and test-retest reliability of a low back pain questionnaire in Zimbabwean adolescents

BACKGROUND

In Zimbabwe, a recent increase in the volume of research on recurrent non-specific low back pain (NSLBP) has revealed that adolescents are commonly affected. This is alarming to health professionals and parents and calls for serious primary preventative strategies to be developed and implemented forthwith. Early identification initiatives should be prioritised in order to curtail the condition and its progression. In an attempt to be proactive in minimising the prevalence of recurrent NSLBP, this study was conducted to evaluate the content validity and test-retest reliability of a survey questionnaire with the aim of proffering a valid and reliable questionnaire which can be used in non-clinical settings to identify adolescents with recurrent NSLBP in Harare, Zimbabwe and determine the possible factors associated with the condition.

METHODS

The study was conducted in two parts. The first part assessed content validity of the questionnaire using four experts derived from academia and clinical practice. The second part evaluated the reliability of the questionnaire among 125 high school-children aged between 13 and 19 years in a test-retest study.

RESULTS

Twenty-six (26) out of thirty questions in the questionnaire had an Item Content Validity index of 1.00, demonstrating complete agreement among content experts. Overall, the Scale Content Validity Index for the questionnaire was 0.97. Item completion for the reliability study was satisfactory. The questionnaire items had kappa values ranging from 0.17 (slight agreement) to 1 (perfect agreement). High levels of reliability were found for the questions on school bag use (k=0.94), sports participation (k=0.97), and lifetime prevalence (k=0.89).

CONCLUSION

Excellent content validity and slight to perfect test-retest reliability was found for the Low Back Pain (LBP) questionnaire. These results are comparable to findings of other studies evaluating the psychometric properties of LBP questionnaires. Cognisant of the limitations of the study, the results of this study suggest that the LBP questionnaire could be used in local studies investigating LBP among adolescents although questions enquiring on functional limitations and sciatica may need further consideration.

Are parents and adolescents in agreement on reporting of recurrent non-specific low back pain in adolescents? A cross-sectional descriptive study

BACKGROUND

Non-specific low back pain is a prevalent symptom in adolescents and is recurrent in some instances. Recent studies have highlighted the marked impact the condition has on daily life of adolescents. However, it is unclear if parents of adolescents reporting recurrent non-specific low back pain know about their child's status. The purpose of the study was to determine the level of agreement between adolescents and their parents in reporting recurrent non-specific low back pain in Harare, Zimbabwe.

METHODS

This cross-sectional study formed part of a large study carried out to ascertain the prevalence of non-specific low back pain in Zimbabwean adolescents. Six hundred and twenty (n = 620) Medical Health Questionnaires were sent to parents. School-children with returned questionnaires and informed consents signed were subsequently eligible to participate. A reliable and validated low back pain study questionnaire was administered to 544 adolescents between the ages of 13 and 19 years randomly selected from government-administered schools. The questionnaire sought to determine adolescents with recurrent NSLBP. The Kappa statistic (k) was used to analyse agreement between adolescents and parental reports on recurrent NSLBP status.

RESULTS

Parental and school-children response rates were acceptable (90.3 and 97.8 %, respectively). The prevalence of recurrent NSLBP was 28.8 % [95 % Confidence Interval, CI = 26.0-31.6]. Both sexes were equally affected [χ (2) (1) =0.19, p = 0.67]. The prevalence increased with age in both sexes [χ (2) trend =90.9, p < 0.001]. Parental reports agreed in 16.3 and 98.7 % for the adolescents with and without recurrent NSLBP respectively. The value of kappa (k) was 0.20 [SE = 0.04; 95 % CI, 0.13-0.27] with a prevalence index and bias index of -0.65 and 0.23, respectively. These results suggest poor strength of the agreement.

CONCLUSIONS

Recurrent non-specific low back pain is relatively common among Zimbabwean adolescents. Most of the parents of school-children with recurrent non-specific low back pain are unaware of the low back pain status of their children. Although this does not dismiss the relevance of non-specific low back pain reported during adolescence, these findings create a need to involve parents in awareness or preventive initiatives against low back pain in schools.
