A meta-analysis of the association between physical demands of domestic labor and back pain among women

The mediating role of depressive symptoms among Turkish population related to gender and low back pain: evidence from a national health survey

BACKGROUND

Low back pain (LBP), though non-life-threatening, burdens healthcare with treatment expenses and work hours lost. Globally, 70-84% experience it, with risk factors tied to societal structure, income, and living conditions, making it a leading cause of disability.

METHODS

This study utilized data from the 2019 Türkiye Health Survey, which consisted of 17,084 individuals aged 15 and above. Our study focused on investigating the factors related to low back pain through a cross-sectional analysis. To analyze these factors, we employed binary multivariate logistic regression. Additionally, we conducted post-hoc analyses to assess the potential mediating effect of depressive symptoms on the relationship between low back pain and gender.

RESULTS

We found that 31.9% of the population experienced low back pain, with women being 58% more likely [aOR = 1.58; 95% CI (1.45-1.73)] than men to report symptoms. Individuals aged 55 + years old had a 90% [aOR = 1.90; 95% CI (1.61-2.23)] chance of experiencing low back pain, indicating an age-related increase. In the general population, having depressive symptoms was 2.49 [95% CI (2.23-2.78)] times more likely associated with low back pain. Our mediation analysis showed that gender (i.e., women vs. men), indicated by direct effects with β-estimates e = 0.78, predicted the likelihood of low back pain. Additionally, the relationship between gender and low back pain, mediated through a history of depressive symptoms, had a significant total indirect effect (i.e., β-estimate given as e = 0.49). Specifically, a history of depressive symptoms accounted for 17.86% [95% CI (9.67-20.10)] of the association between women having a higher likelihood of low back pain compared to men.

CONCLUSION

We observed that a higher likelihood of low back pain associated with gender and aging. Additionally, BMI served as a significant predictor, particularly in adults. Depression mediated the association between gender and low back pain. Acknowledging these associations may help identify and address contributing factors to LBP, potentially increasing awareness and alleviating the burden. Policymakers and healthcare professionals may consider these findings when developing prevention and treatment programs for low back pain.

Beneficial and harmful effects of physical activity on care-seeking for low back pain: the AUTBACK study

PURPOSE

People who seek more care for low back pain (LBP) tend to experience poorer recovery (e.g. higher pain and disability levels). Understanding the factors associated with care-seeking for LBP might improve patient outcomes and potentially alleviate the burden of LBP on global health systems. This study aimed to investigate the relationship between different intensities, volumes, and domains of physical activity and care-seeking behaviours, in people with a history of LBP.

METHODS

Longitudinal data from adult twins were drawn from the AUstralian Twin BACK study. The primary outcome was the total self-reported frequency (counts) of overall utilisation of care for LBP, over 1 year. Secondary outcomes were the utilisation of health services, and the utilisation of self-management strategies, for LBP (assessed as total frequency over 1 year). Explanatory variables were device-based measures of sedentary behaviour and moderate-to-vigorous intensity physical activity, and self-reported physical workload, and work, transport, household, and leisure domain physical activity, at baseline.

RESULTS

Data from 340 individuals were included. Median age was 56.4 years (IQR 44.9-62.3 years) and 73% of participants were female. Medium-to-high baseline volumes of sedentary behaviour were significantly associated with greater counts of overall care utilisation (IRR 1.60, 95%CI 1.04-2.44) and utilisation of self-management strategies (IRR 1.60, 95%CI 1.02-2.50) for LBP, over 1 year. Medium-to-high baseline volumes of household domain physical activity were significantly associated with greater counts of utilising self-management strategies for LBP over 1 year (IRR 1.62, 95%CI 1.04-2.53). No explanatory variables were associated with the utilisation of health services for LBP.

CONCLUSION

People who engage in higher baseline volumes of sedentary behaviour or physical activity in the household setting (e.g. housework, gardening, yard work, general household maintenance) utilise 1.6 times more care for LBP over 1 year. Findings suggest that higher volumes of these behaviours may be harmful for LBP. No intensities, volumes, or domains of physical activity demonstrated clear benefits for LBP. Where feasible, patients and clinicians should collaborate to screen and develop strategies to reduce engagement in sedentary behaviour or physical activity in the household setting. Contextual factors (e.g. patient symptom severity, sociocultural roles, occupational demands) should be considered when devising appropriate behaviour change strategies.

Occupation-based demographic, clinical, and psychological presentation of spine pain: A retrospective analysis of 71,727 patients from urban India

BACKGROUND

Although many studies have investigated the physical and ergonomic risks of spine pain in specific occupation groups, the literature is lacking on occupation-based clinical and psychological presentation in patients with spine pain.

OBJECTIVE

To analyze occupation-based variation in demographic, clinical, and psychological presentation in patients with spine pain.

METHODS

This retrospective study analyzed the clinical data of 71727 patients with spine pain visiting a chain of spine rehabilitation clinics. Demographic and clinical variables such as gender, age, affected site, symptom duration, clinical symptoms and presentation, pain intensity, disability, and STarT Back Screening Tool (SBT) risk were compared between 9 occupational groups.

RESULTS

The service and sales workers (44%) and students (43.5%) groups had the highest percentage of patients who presented with central spine pain; military personnel had the highest percentage of patients who presented with unilateral radicular pain (51.5%); and the retired or unemployed group had the highest percentage of patients who presented with severe myotomal loss (grade≤3) (6%). Homemakers had significantly higher pain intensity and disability (p < 0.001) and had the highest percentage of patients who presented with severe pain (47%), severe and crippled disability (59.5%), and medium to high risk (59%) with SBT when compared to other occupational groups.

CONCLUSION

Patients with spine pain showed variation in demographic, clinical, and psychological presentation based on their occupation. The findings of this study can be the basis for identifying risk factors for spine pain and helping plan preventive and treatment measures based on their occupation.

Pain, Physical Demands at Work, and Future Work Expectations Among Older Adults in the United States

Background and Objectives

In the United States, pain is becoming increasingly prevalent among older adults at the same time as policies are incentivizing work longer. Given that pain and physically demanding jobs are both linked to early retirement and they often go hand-in-hand, it is important to assess how the unique effects of pain and physical work demands may interact in predicting future work expectations.

Research Design and Methods

Using Health and Retirement Study data (1998, 2004, 2010, and 2016 waves), we assess how pain and physical job demands influence future work expectations of 10,358 adults at midlife (ages 51-56), after accounting for sociodemographic, job, health, and financial characteristics.

Results

Compared to men with no pain, activity-interfering pain was associated with low expectations of full-time work past 62 regardless of job demands, while noninterfering pain was associated with 62% higher odds (odds ratio [OR] = 1.62, 95% confidence interval [CI]: 1.35-1.93) of expecting not to work full-time past age 62 only among those with physically demanding jobs. Having both interfering pain and a physically demanding job was associated with increased odds of expecting not to work full-time past age 65 for men (OR = 1.25, 95% CI: 1.06-1.47) and past age 62 for women (OR = 1.18, 95% CI: 1.00-1.39).

Discussion and Implications

The co-occurrence of physically demanding work with pain-particularly activity-interfering pain-is associated with low expectations of full-time work past ages 62 and 65 for adults at midlife. Working longer may be feasible for older adults whose pain does not interfere with work, but unrealistic for individuals facing both pain and physically demanding work.

Factors associated with the incidence and worsening of back pain during the first wave of COVID-19 in Brazil

Abstract The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson’s Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

Assessing the relationship between domestic work experience and musculoskeletal health among rural Nigerian women

BACKGROUND

Women performing strenuous domestic tasks (especially those in developing countries) are at risk of experiencing musculoskeletal pain (MSP). Physical, psychosocial, and social conditions of work in rural environments contribute to women's domestic work experiences (DWEs) and the risk of MSP. The impact of DWEs on women's health is especially severe in water-insecure countries like Nigeria. This study examines the relationship between a recently developed measure of DWEs and self-reported pain in the lower back (LBP), neck/shoulder (NSP), and elbow/hand/wrist regions (EHWP) among rural Nigerian women.

METHODS

Interviewer-administered survey data were collected from 356 women in four rural communities of Ibadan, Nigeria. Binary and ordinal logistic regression models were used to examine the relationship between DWE factor scores, sociodemographic characteristics, and musculoskeletal pain symptoms and severity after controlling for sociodemographic covariates. Effect estimates of association were presented using the odds ratio (OR), and the corresponding 95% confidence interval (CI) at p-value of 0.05.

FINDINGS

Among 356 participants, the 2-month prevalence of LBP was 58%, NSP was 30%, and EWHP 30%. High DWE scores were significantly associated with higher odds of experiencing and having more severe LBP, NSP, and EHWP. Specifically, the odds of LBP [(OR = 2.88; 95% CI = 1.64-5.11), NSP (OR = 4.58; 95% CI = 2.29-9.40) and EHWP (OR = 1.88; 95% CI = 1.26-3.77)] were significantly higher among women who perceived their domestic work responsibilities as very stressful (i.e., 'high stress appraisal') compared to those with lower stress appraisal scores. Those who were time-pressured and had less autonomy over familial duties (i.e., 'high demand/low control') had significantly higher odds of LBP [(OR = 2.58; 95% CI = 1.64-4.09) and NSP (OR = 1.49; 95% CI = 1.24-2.58)]. Frequently fetching and carrying water over long distances and time (i.e., 'high water sourcing and carriage') was also associated with higher odds of LBP [(OR = 1.31; 95% CI = 1.09-1.79) and NSP (OR = 1.20; 95% CI = 1.08-1.76).

CONCLUSION

Strenuous and stressful DWEs were associated with MSP among rural Nigerian women. This study provides new evidence on how the physical, social, and psychosocial factors of domestic work can increase women's risk of MSP.

Understanding Rural Women's Domestic Work Experiences (DWE) in Ibadan, Nigeria: Development of a Measurement Tool Using Confirmatory Factor Analysis

Gender norms prescribe domestic labor as primarily a female's responsibility in developing countries. Many domestic tasks depend on access to water, so the physical, emotional, and time demands of domestic labor may be exacerbated for women living in water-insecure environments. We developed a set of domestic work experience (DWE) measures tailored to work in rural areas in developing countries, assessed rural Nigerian women's DWE, and examined relationships among the measures. Interviewer-administered survey data were collected between August and September from 256 women in four rural Nigerian communities. Latent factors of DWE were identified by analyzing survey items using confirmatory factor analysis. Pearson's correlation was used to examine relationships among latent factor scores, and multivariate linear regression models were used to determine if factor scores significantly differed across socio-demographic characteristics. The DWE measures consisted of latent factors of the physical domain (frequency of common domestic tasks, water sourcing and carriage, experience of water scarcity), the psychosocial domain (stress appraisal and demand-control), and the social domain (social support). Significant correlations were observed among the latent factors within and across domains. Results revealed the importance of measuring rural Nigerian women's DWE using multiple and contextual approaches rather than relying solely on one exposure measure. Multiple inter-related factors contributed to women's DWE. Water insecurity exacerbated the physical and emotional demands of domestic labor DWE varied across age categories and pregnancy status among rural Nigerian women.
