Disability,depression and somatization in a low back pain population

Objective: The aim of this study was to determine the prevalence of low back pain (LBP) in a primary care setting population and examine its association with the symptoms of depression and somatization. Methods: This is a cross‐sectional study, utilising a survey carried out in primary health care clinics (PHCs) in Al‐Ain, United Arab Emirates (UAE). A multistage stratified sampling design was used and a representative sample of 1304 UAE nationals aged 18–65 years who attended PHC clinics for any reason were included and 1103 (84.5%) subjects agreed to participate and responded to the questionnaire during a period from June 2001 to January 2002. A specially designed questionnaire with three parts was used for the data collection: socio‐demographic information of the studied subjects, modified version of the Roland‐Morris scale for evaluating back‐related functional disability and SCL‐90 R for depression and somatization subscales was used to assess depressive and somatic symptoms. Results: Of the total number of subjects surveyed (1103), 586 (53.1%) were men and 517 (46.9%) women. The mean age was 34.9 ± 13.4 years for men and 33.5 ± 11.8 years for women. The prevalence of LBP in the studied subjects was 64.7% (95% CI, 60.7–68.5] with 46.7% among men and 53.3% among women. There were a significant differences between the subjects with LBP and without LBP with respect to gender (P < 0.001), body mass index (BMI) (P < 0.001), occupational status (P < 0.001) and living environment (P = 0.016). Functional disability was higher in patients with LBP. Young patients in aged 15–34 years, patients with preparatory/secondary educational level and students showed higher depressive symptoms. A similar pattern was found in patients with somatic symptoms. Factor analysis revealed a strong association between depression and somatization in LBP patients. Conclusions: Functional disability was higher in with LBP. Furthermore, symptoms of depression and somatization are prevalent among LBP patients.     

Minor Psychiatric Morbidity, Its Prevalence and Outcome in a Cohort of Civil Servants A Seven-year Follow-up Study

During the years 1979–1986, a cohort of direct entrantexecutive officers in the Civil Service were followed up toexamine the prevalence and outcome of minor psychiatric morbidityin an occupational setting. All studies using epidemiologicalstandardized research methods agree, that prevalence rates arehigh in occupational settings. As in primary care settings,half of the illness episodes followed a chronic course, whichemphasizes the need for early detection and prompt managementof these conditions, and for evaluative studies of interventionstrategies.     

Reflection on the geographic distribution of multiple sclerosis in France

The geographic distribution of multiple sclerosis within the 95 Départements and the 21 Régions of France was defined from a 1986 nationwide prevalence series derived from questionnaires. This indicated a significant clustering of high frequency regions in the northeastern part of the country with most significantly low areas in the south and west. Distributions were similar to those for MS death rates by Département and Région for 1968–1977, indicating geographic stability over time; but there was also evidence of diffusion over time. The 1986 prevalence distribution was also compared with all published prevalence rates for communities of France. From all these resources we conclude that all of France falls within the "high frequency zone" for MS, that the nationwide prevalence rate is at least 50 per 100000 population, and that there is evidence of geographic clustering of the disease with temporal spread of the cluster.

Maternal mortality and maternity care from 1990 to 2005: uneven but important gains

Maternal mortality continues to be the major cause of death among women of reproductive age in many countries. Data from published studies and Demographic and Health Surveys show that gains in reducing maternal mortality between 1990 and 2005 have been modest overall. In 2005, there were about 536,000 maternal deaths, and the maternal mortality ratio was estimated at 400 per 100,000 live births, compared to 430 in 1990. Noteworthy declines took place in east Asia (4% per year) and north Africa (3% per year). Maternal deaths and mortality ratios were highest in sub-Saharan Africa and southeast Asia and low in east Asia and Latin America/Caribbean. In 11 of 53 countries with data, fewer than 25% of women had had at least four antenatal visits. About 63% of births were attended by a skilled attendant: from 47% in Africa to 88% in Latin America/Caribbean. In 16 of 23 countries with data, less than 50% of the recommended levels of emergency obstetric care had been fulfilled. Only 61% of women who delivered in a health facility in 30 developing countries received post-partum care, and far fewer who gave birth at home. Countries with maternal mortality ratios of 750+ per 100,000 live births shared problems of high fertility and unplanned pregnancies, poor health infrastructure with limited resources and low availability of health personnel. The task ahead is enormous.     

Cultural adaptation is associated with atopy and wheezing among children of Turkish origin living in Germany

BACKGROUND: Turkish children have been found to suffer less from atopic diseases than their German peers. The underlying causes are unknown. OBJECTIVE: To evaluate rates of sensitization and atopic disease among children in Germany with German or Turkish ethnicity and different degrees of cultural adaptation. METHODS: This was a cross-sectional study. The setting was screening for school eligibility in an inner-city district of Berlin/Germany. The participants were preschool children born in Germany with double German or double Turkish parental citizenship. Cultural adaptation of Turkish children was assessed by the language parents used to communicate with their child: only Turkish (n = 60, group A); Turkish and German (n = 269, group B); and only German (n = 103, group C). Group D contained children from German parents (n = 383). The main outcome measures were specific sensitization to common aeroallergens (CAP-System, Pharmacia Phadiatop >or= 0.35 kU/L), and lifetime and 1-year prevalences of allergic disease symptoms (ISAAC questionnaire in German and Turkish, Mantel-Haenszel test for trend). RESULTS: Sensitization rates for groups A, B, C and D were 8.0%, 6.8%, 18.9% and 18.3%, respectively (P = 0.004). The corresponding prevalence rates for wheeze ever were 6.7%, 9.3%, 12.6% and 21.3% (P < 0.001), wheeze in the past year 3.3%, 3.7%, 9.7% and 10.2% (P = 0.001), itchy rash ever 3.3%, 6.3%, 8.7% and 13.7% (P < 0.001), itchy rash in the past year 1.7%, 3.7%, 4.9% and 9.5% (P < 0.001), respectively. No significant differences were found for hay fever symptoms. CONCLUSIONS: Higher cultural adaptation is correlated with higher rates of allergic sensitization and disease among children of Turkish origin living in Berlin. This correlation suggests that environmental rather than genetic differences are responsible for the differences observed.     

Prevalence of occupational allergy due to live fish bait

BACKGROUND: Larvae of insects and worms, used as live fish bait (LFB), are a common source of allergy in anglers and occupationally exposed workers, but the prevalence and predictors have not yet been investigated. OBJECTIVE: This study assessed the prevalence and associated factors of occupational allergy in workers exposed to LFB. METHODS: We assessed the prevalence of sensitization to LFB and work-related symptoms (WRS) in 76 workers occupationally exposed to it. All workers completed a case history questionnaire and underwent skin prick tests (SPT) for common aeroallergens and bluebottle (Calliphora vomitoria), bee moth (Galleria mellonella), mealworm (Tenebrio molitor), and gusano rojo (Cilecomadia moorei). Specific IgE were tested in 64 subjects. Two-thirds of the workers had a high level of LFB exposure. RESULTS: Sensitization to LFB was found in 24 workers (31.6%). Seven subjects (9.2%) reported WRS (asthma in 3, rhinoconjunctivitis in 5, and contact urticaria in 1), and 5 were positive for SPT and serum IgE to one or more LFB extracts. One was also exposed to LFB while fishing. Sensitization to LFB extracts and WRS were strongly associated (Odds Ratio = 6.6, P < 0.05). The 7 subjects with WRS had been exposed longer than asymptomatic subjects with positive skin tests to LFB (P < 0.05). No differences in sex, age, smoking habit, duration or level of exposure, and atopy were detected in symptomatic or in sensitized subjects, compared with normal workers. CONCLUSION: Sensitization to LFB and WRS are relatively frequent in occupationally exposed workers. No associated factors of occupational allergy to LFB could be detected.     

Epidemiology of multiple sclerosis in the county of Vestfold, eastern Norway: incidence and prevalence calculations

The county of Vestfold in the South-eastern part of Norway has undergone two incidence and prevalence surveys on multiple sclerosis. The prevalence of definite/probable MS on January 1.1963 was 61.6/100000. Based on the same diagnostic criteria, the present study reports a slight increase in prevalence to 86.4/100000 on January 1st 1983. The average annual incidence was calculated for 5 years periods from 1953 to 1983. The time periods 1953–1962 and 1973–1977 showed age-adjusted incidence rates between 4.50 and 5.49/100000 while the 10–year period 1963–1972 showed significantly lower rates. The fluctuating pattern of MS incidence and prevalence over time supports the view that MS is not a stable disease, and that exogenous factors are influencing the disease pattern.

Incidence and prevalence of the sexual dysfunctions: A critical review of the empirical literature

The research which has assessed the incidence and prevalence of sexual dysfunctions is reviewed. Twenty-three studies are evaluated. Studies completed with community samples indicate a current prevalence of 5–10% for inhibited female orgasm, 4–9% for male erectile disorder, 4–10% for inhibited male orgasm, and 36–38% for premature ejaculation. Stable community estimates with regard to the current prevalence of female sexual arousal disorder, vaginismus, and dyspareunia are not available. Recent studies completed with clinical samples suggest an increase in the frequency of orgasmic and erectile dysfunction and a decrease in premature ejaculation as presenting problems. Desire disorders have increased as presenting problems in sex clinics, with recent data indicating that males outnumber females. Methodological limitations of these studies are identified and suggestions for future research are offered.
