Exercise for the prevention of low back and pelvic girdle pain in pregnancy: A meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: The effect of exercise in prevention of low back and pelvic girdle pain during pregnancy is uncertain. This study aimed to assess the effect of exercise on low back pain, pelvic girdle pain and associated sick leave. DATABASES AND DATA TREATMENT: Literature searches were conducted in PubMed, EMBASE, Cochrane Library, Google Scholar, ResearchGate and ClinicalTrials.gov databases from their inception through May 2017. Randomized controlled trials (RCTs) were eligible for inclusion in the review if they compared an exercise intervention with usual daily activities and at least some of the participants were free from low back pain and/or pelvic girdle pain at baseline. Methodological quality of included studies was evaluated using the Cochrane Collaboration's tool. A random-effects meta-analysis was performed, and heterogeneity and publication bias were assessed. RESULTS: Eleven randomized controlled trials (2347 pregnant women) qualified for meta-analyses. Exercise reduced the risk of low back pain in pregnancy by 9% (pooled risk ratio (RR) = 0.91, 95% CI 0.83-0.99, I2  = 0%, seven trials, N = 1175), whereas it had no protective effect on pelvic girdle pain (RR = 0.99, CI 0.81-1.21, I2  = 0%, four RCTs, N = 565) or lumbopelvic pain (RR = 0.96, CI 0.90-1.02, I2  = 0%, eight RCTs, N = 1737). Furthermore, exercise prevented new episodes of sick leave due to lumbopelvic pain (RR = 0.79, CI 0.64-0.99, I2  = 0%, three RCTs, N = 1168). There was no evidence of publication bias. CONCLUSION: Exercise appears to reduce the risk of low back pain in pregnant women, and sick leave because of lumbopelvic pain, but there is no clear evidence for an effect on pelvic girdle pain. SIGNIFICANCE: Exercise has a small protective effect against low back pain during pregnancy.

The determinants of service complexity in children with intellectual disabilities.

BACKGROUND: To date, little is known about the predictors of healthcare service utilisation in children with intellectual disability (ID). The aim of this study was to identify the factors associated with service complexity in children with ID in Ontario, Canada. METHODS: The population of this cross-sectional study consisted of 330 children with ID ages 4 to 18 years who accessed mental health services from November of 2012 to June of 2016 in four agencies. All participants completed the interRAI Child and Youth Mental Health and Developmental Disability Assessment Instrument, which is a semi-structured clinician-rated assessment that covers a range of common issues in children with ID. The outcome of this study was a service complexity variable based on (1) mental health service utilisation including any services provided to the child and (2) the management involved in providing that care. Eight individual items were summed, resulting in a scale that ranged from 0 to 8. Scores were then dichotomised into two groups: a score of 0-2 identified children with a low service complexity and a score of 3 or higher identified children with a high service complexity. RESULTS: After adjustment for other covariates, gender was not associated with service complexity. Children aged 11-14 years and children with autism spectrum disorder used over twofold higher levels of service complexity than children aged equal to or less than 10 years or children with other causes of ID. Moreover, victims of bullying, high scores on the family functioning scale or learning or communication disorder were associated with greater service complexity. CONCLUSIONS: The findings of this study indicate that a variety of factors are related to service complexity ranged from children's nonclinical (age and experiences of bullying) to clinical (e.g. aggression, learning/communication problems and autism spectrum disorder) characteristics.

The prevalence of antenatal and postnatal co-morbid anxiety and depression: a meta-analysis.

To date, the precise prevalence of co-morbidity of anxiety and depression in the perinatal period is not well known. We aimed to estimate the prevalence of co-morbid anxiety and depression in the antenatal and postnatal periods. Systematic searches of multiple electronic databases were conducted for studies published between January 1950 and January 2016. We included 66 (24 published and 42 unpublished) studies incorporating 162 120 women from 30 countries. Prevalence of self-reported antenatal anxiety symptoms and mild to severe depressive symptoms was 9.5% [95% confidence interval (CI) 7.8-11.2, 17 studies, n = 25 592] and of co-morbid anxiety symptoms and moderate/severe depressive symptoms was 6.3% (95% CI 4.8-7.7, 17 studies, n = 27 270). Prevalence of a clinical diagnosis of any antenatal anxiety disorder and depression was 9.3% (95% CI 4.0-14.7, 10 studies, n = 3918) and of co-morbid generalized anxiety disorder and depression was 1.7% (95% CI 0.2-3.1, three studies, n = 3085). Postnatally between 1 and 24 weeks postpartum, the prevalence of co-morbid anxiety symptoms and mild to severe depressive symptoms was 8.2% (95% CI 6.5-9.9, 15 studies, n = 14 731), while co-morbid anxiety symptoms and moderate/severe depressive symptoms was 5.7% (95% CI 4.3-7.1, 13 studies, n = 20 849). The prevalence of a clinical diagnosis of co-morbid anxiety and depression was 4.2% (95% CI 1.9-6.6, eight studies, n = 3251). Prevalence rates did not differ with regard to year of publication, country income, selection bias and attrition bias. The results suggest that co-morbid perinatal anxiety and depression are prevalent and warrant clinical attention given the potential negative child developmental consequences if left untreated. Further research is warranted to develop evidence-based interventions for prevention, identification and treatment of this co-morbidity.

Identifying women at risk for postpartum anxiety: a prospective population-based study.

OBJECTIVE: To develop a multifactorial model to predict anxiety symptomatology at 8 weeks postpartum. METHOD: In a population-based study, 522 women in a health region near Vancouver, Canada, completed questionnaires at 1, 4, and 8 weeks postpartum. Questionnaires included risk factors measured at 1 week (sociodemographic, biological, pregnancy-related, life stressors, social support, obstetric, and maternal adjustment). Sequential logistic regression was completed to develop a predictive model of anxiety symptomatology at 8 weeks (State-Trait Anxiety Inventory score >40). RESULTS: The prevalence of anxiety symptomatology at 1, 4, and 8 weeks postpartum was 22.6%, 17.2%, and 14.8% respectively. In multivariable models, anxiety symptomatology at 1 week (aOR 2.78, 95% CI: 1.04-7.43), multiparous parity (aOR 3.29, 95% CI: 1.28-8.48), history of psychiatric problems (aOR 3.07, 95% CI: 1.19-7.97), perceived stress (1 SD increase: aOR 4.92, 95% CI: 2.62-9.26), and childcare stress (1 SD increase: aOR 1.63, 95% CI: 1.01-2.64) were independent predictors of anxiety symptomatology at 8 weeks. CONCLUSION: While a significant proportion of women experience anxiety symptomatology following childbirth, multiparous women with a psychiatric history who have high levels of diverse stress are at greatest risk. These key factors may be used to promote early identification and secondary preventive interventions.

Leisure-time physical activity and sciatica: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: The role of leisure-time physical activity in sciatica is uncertain. This study aimed to assess the association of leisure-time physical activity with lumbar radicular pain and sciatica. DATABASES AND DATA TREATMENT: Literature searches were conducted in PubMed, Embase, Web of Science, Scopus, Google Scholar and ResearchGate databases from 1964 through August 2015. A random-effects meta-analysis was performed, and heterogeneity and small-study bias were assessed. RESULTS: Ten cohort (N = 82,024 participants), four case-control (N = 9350) and four cross-sectional (N = 10,046) studies qualified for meta-analysis. In comparison with no regular physical activity, high level of physical activity (≥4 times/week) was inversely associated with new onset of lumbar radicular pain or sciatica in a meta-analysis of prospective cohort studies [risk ratio (RR) = 0.88, 95% CI 0.78-0.99, I2  = 0%, 7 studies, N = 78,065]. The association for moderate level of physical activity (1-3 times/week) was weaker (RR = 0.93, CI 0.82-1.05, I2  = 0%, 6 studies, N = 69,049), and there was no association with physical activity for at least once/week (RR = 0.99, CI 0.86-1.13, 9 studies, N = 73,008). In contrast, a meta-analysis of cross-sectional studies showed a higher prevalence of lumbar radicular pain or sciatica in participants who exercised at least once/week [prevalence ratio (PR) = 1.29, CI 1.09-1.53, I2  = 0%, 4 studies, N = 10,046], or 1-3 times/week (PR = 1.34, CI 1.02-1.77, I2  = 0%, N = 7631) than among inactive participants. There was no evidence of small-study bias. CONCLUSIONS: This meta-analysis suggests that moderate to high level of leisure physical activity may have a moderate protective effect against development of lumbar radicular pain. However, a large reduction in risk (>30%) seems unlikely. WHAT DOES THIS REVIEW ADD: Leisure-time physical activity may reduce the risk of developing lumbar radicular pain.

The effect of excess body mass on the risk of carpal tunnel syndrome: a meta-analysis of 58 studies.

We aimed to estimate the effects of overweight and obesity on carpal tunnel syndrome (CTS), and to assess whether sex modifies the associations. Literature searches were conducted in PubMed, Embase, Web of Science, Scopus, Google Scholar and ResearchGate databases from 1953 to February 2015. Fifty-eight studies consisting of 1,379,372 individuals qualified for a meta-analysis. We used a random-effects meta-analysis, assessed heterogeneity and publication bias, and performed sensitivity analyses. Overweight increased the risk of CTS or carpal tunnel release 1.5-fold (pooled confounder-adjusted odds ratio [OR] = 1.47, 95% CI 1.37-1.57, N = 1,279,546) and obesity twofold (adjusted OR = 2.02, 95% CI 1.92-2.13, N = 1,362,207). Each one-unit increase in body mass index increased the risk of CTS by 7.4% (adjusted OR = 1.074, 95% CI 1.071-1.077, N = 1,258,578). Overweight and obesity had stronger effects on carpal tunnel release than CTS. The associations did not differ between men and women, and they were independent of study design. Moreover, the associations were not due to bias or confounding. Excess body mass markedly increases the risk of CTS. As the prevalence of overweight and obesity is increasing globally, overweight-related CTS is expected to increase. Future studies should investigate whether a square-shaped wrist and exposure to physical workload factors potentiate the adverse effect of obesity on the median nerve.

Association between comorbidity and erectile dysfunction in patients with diabetes.

The aims of this study were to determine the prevalence of erectile dysfunction (ED) and its relationship with comorbidity in patients with diabetes. The study population comprised of 312 consecutive patients aged 20 years or over residing in the city of Hamadan in Iran in 2005. Depression was assessed by the modified version of the Beck Depression Inventory (BDI-II) and ED by the short form of the International Index of Erectile Function (IIEF-5) questionnaire. Potential confounding was controlled by stratification and by a logistic regression model. The prevalence of moderate or complete ED (IIEF score

Decreasing trend in the incidence of stomach cancer in Mumbai, India, during 1988 to 1999.

The time trend in incidence of stomach cancer in males and females in Mumbai, India during 1988 to 1999 was estimated using data collected by the Bombay Population-based Cancer Registry. During the 12-year period, a total of 3657 stomach cancer cases (3.9% of all cancers) were registered by the Bombay Population-based Cancer Registry of which 2467 (5.1% of all male cancers) were in males and 1184 (2.6% of all female cancers) in females. For evaluation of the trend, we applied a linear regression model based on the logarithm of the observed incidence rates. The annual percentage changes were also computed for the incidence rates for evaluating the time trend. A statistically significant decreasing trend in the overall age-adjusted incidence rates of stomach cancer was observed during the period 1988 to 1999, with an yearly decrease of 4.44% in males and 2.56% in females. This decrease was most striking in males in the age groups 40-59 and 60+, and in females only in the age group 40-59. The probability estimates indicated that one out of every 92 men and one out of every 187 women will contract a stomach cancer at some time in their whole life and 95% of the chance is after his or her 40th birthday. The decreasing trend in the age-adjusted incidence rates of stomach cancer in both the sexes indicates that there is a critical change in the etiology of this cancer. The findings may provide clues relating to various life-style and environmental changes impacting on stomach cancer incidence.
