Behavioural interventions for HIV positive prevention in developing countries: a systematic review and meta-analysis

Objective

To assess the evidence for a differential effect of positive prevention interventions among individuals infected and not infected with human immunodeficiency virus (HIV) in developing countries, and to assess the effectiveness of interventions targeted specifically at people living with HIV.

Methods

We conducted a systematic review and meta-analysis of papers on positive prevention behavioural interventions in developing countries published between January 1990 and December 2006. Standardized methods of searching and data abstraction were used. Pooled effect sizes were calculated using random effects models.

Findings

Nineteen studies met the inclusion criteria. In meta-analysis, behavioural interventions had a stronger impact on condom use among HIV-positive (HIV+) individuals (odds ratio, OR: 3.61; 95% confidence interval, CI: 2.61–4.99) than among HIV-negative individuals (OR: 1.32; 95% CI: 0.77–2.26). Interventions specifically targeting HIV+ individuals also showed a positive effect on condom use (OR: 7.84; 95% CI: 2.82–21.79), which was particularly strong among HIV-serodiscordant couples (OR: 67.38; 95% CI: 36.17–125.52). Interventions included in this review were limited both in scope (most were HIV counselling and testing interventions) and in target populations (most were conducted among heterosexual adults or HIV-serodiscordant couples).

Conclusion

Current evidence suggests that interventions targeting people living with HIV in developing countries increase condom use, especially among HIV-serodiscordant couples. Comprehensive positive prevention interventions targeting diverse populations and covering a range of intervention modalities are needed to keep HIV+ individuals physically and mentally healthy, prevent transmission of HIV infection and increase the agency and involvement of people living with HIV.     

Prevalence and Predictors of Tuberculosis Coinfection among HIV-Seropositive Patients Attending the Aminu Kano Teaching Hospital,Northern Nigeria

Background

The HIV/AIDS epidemic has been accompanied by a severe epidemic of tuberculosis (TB), although the prevalence of coinfection is largely unknown, especially in developing countries, including Nigeria. The aim of this study was to determine the prevalence and predictors of TB coinfection among HIV-seropositive Nigerians.

Methods

The case files of HIV/AIDS patients attending Aminu Kano Teaching Hospital, Nigeria from January to December 2006 were reviewed.

Results

A total of 1320 HIV/AIDS patients had complete records and were reviewed, among which 138 (10.5%) were coinfected with TB (95% CI, 8.9% to 12.2%). Pulmonary TB was diagnosed in 103 (74.6%) patients, among whom only 18 (17.5%) were sputum-positive. Fifty (36.2%) coinfected patients had some type of extrapulmonary TB (EPTB); 15 had both pulmonary TB and EPTB. Among the 35 patients with EPTB only, 20 (57.1%) had abdominal TB, 5 (14.3%) had TB adenitis, 5 (14.3%) had spinal TB, 3 (8.6%) were being monitored for tuberculous meningitis, and 1 (2.9%) each had renal TB and tuberculous adrenalitis. The highest prevalence of TB, 13.7% (n = 28), was seen among patients aged 41–50 years. TB coinfection was significantly associated with marital status, WHO clinical stage, and CD4 count. Marital status (OR, 2.1; 95% CI, 1.28–3.59; P = 0.04), WHO clinical stage at presentation (4.81; 1.42–8.34; P = 0.001), and baseline CD4 count (2.71; 1.51–6.21; P = 0.02) remained significant predictors after adjustment for confounding.

Conclusions

The moderately high prevalence of TB among HIV-seropositive patients underscores the urgent need for strategies that lead to rapid identification and treatment of coinfection with active or latent TB.Key words: tuberculosis, HIV, coinfection, prevalence, Kano, Nigeria     

Multidrug-resistant tuberculosis in Belarus: the size of the problem and associated risk factors

Objective

To assess the problem of multidrug-resistant tuberculosis (MDR-TB) throughout Belarus and investigate the associated risk factors.

Methods

In a nationwide survey in 2010–2011, 1420 tuberculosis (TB) patients were screened and 934 new and 410 previously treated cases of TB were found to meet the inclusion criteria. Isolates of Mycobacterium tuberculosis from each eligible patient were tested for susceptibility to anti-TB drugs. Sociobehavioural information was gathered in interviews based on a structured questionnaire.

Findings

MDR-TB was found in 32.3% and 75.6% of the new and previously treated patients, respectively, and, 11.9% of the 612 patients found to have MDR-TB had extensively drug-resistant TB (XDR-TB). A history of previous treatment for TB was the strongest independent risk factor for MDR-TB (odds ratio, OR: 6.1; 95% confidence interval, CI: 4.8–7.7). The other independent risk factors were human immunodeficiency virus (HIV) infection (OR: 2.2; 95% CI: 1.4–3.5), age < 35 years (OR: 1.4; 95% CI: 1.0–1.8), history of imprisonment (OR: 1.5; 95% CI: 1.1–2.0), disability sufficient to prevent work (OR: 1.9; 95% CI: 1.2–3.0), alcohol abuse (OR: 1.3; 95% CI: 1.0–1.8) and smoking (OR: 1.5; 95% CI: 1.1–2.0).

Conclusion

MDR-TB is very common among TB patients throughout Belarus. The numerous risk factors identified for MDR-TB and the convergence of the epidemics of MDR-TB and HIV infection call not only for stronger collaboration between TB and HIV control programmes, but also for the implementation of innovative measures to accelerate the detection of TB resistance and improve treatment adherence.     

Prevalence and factors associated with sedentary behavior in adolescents

OBJECTIVE

To analyze the prevalence of sedentary behavior and associated factors in adolescents.

METHODS

A cross-sectional study with adolescents aged 10 to 17 years, of both sexes, belonging to a 1994-1999 birth cohort in the city of Cuiabá, MT, Central Western Brazil. Data were collected using a questionnaire containing sociodemographic, economic, lifestyle and anthropometric variables. Sedentary behavior was determined as using television and/or computer/video games for a time greater than or equal to 4 hours/day. Associations with sedentary behavior were evaluated using body mass index in childhood and adolescence and sociodemographic and behavioral variables using hierarchical logistic regression.

RESULTS

The overall prevalence of sedentary behavior was 58.1%. Of the 1,716 adolescents evaluated, 50.7% (n = 870) were male. In multivariate analysis, after adjustment for confounding factors, the variables that remained associated with sedentary behavior were: age (14 and over) (OR = 3.51, 95%CI 2.19;5.60); higher socioeconomic class (OR = 3.83, 95%CI 2.10;7.01), higher level of maternal education (OR = 1.81, 95%CI 1.09;3.01); living in the country (OR = 0.49, 95%CI 0.30;0.81); insufficient physical activity (OR = 1.25, 95%CI 1.02;1.53); experimentation with alcoholic beverages (OR = 1.34, 95%CI 1.08;1.66) and being overweight in adolescence (OR = 1.33, 95%CI 1.06;1.68).

CONCLUSIONS

The high proportion of adolescents in sedentary activities and the lack of association with being overweight in childhood, indicates the need for educational initiatives to reduce multiple risk behaviors. Encouraging physical activity in young people as a way of reducing sedentary behavior and, consequently, being overweight is fundamental.     

Nonadherence to Antiretroviral Therapy Among People Living with HIV/AIDS Attending Two Tertiary Care Hospitals in District of Northern India

Introduction:

Adherence to antiretroviral therapy is a principal predictor for the success of human immunodeficiency virus (HIV) treatment. It remains as a challenge to acquired immunodeficiency syndrome (AIDS) treatment and care with the widespread of the associated risks. Therefore, study aims to assess nonadherence level and factors associated with nonadherence to ART among people living with HIV/AIDS (PLHA).

Materials and Methods:

A hospital-based, cross-sectional study was conducted at two tertiary care hospital of Lucknow. A total of 322 adult HIV-positive patients registered in the ART center were included. Systematic random sampling was used to recruit patients. Nonadherence was assessed on the basis of pill count method.

Results:

A total of 10.9% of patients were found to be nonadherent to ART. Principal causes cited were being busy with other work (40.0%), felt sick or ill (28.5%), not having money (14.2%), and being away from home (11.4). Multivariate logistic regression analysis revealed that nonadherence was significantly associated with nonbeneficial perceptions towards ART (odds ratio (OR) 18.5; 95% confidence interval (CI) 3.2-106.6; P = 0.001), being counseled for adherence for more than 3 months (OR 13.9; 95% CI 1.6-118.9; P = 0.01), presence of depression (OR 2.6; 95% CI 1.0-6.7; P = 0.04), and those who were not satisfied with healthcare facilities (OR 5.63; 95% CI 1.88-16.84; P = 0.00).

Conclusion:

Although adherence to ART varies between individuals and over time, the factors that affect nonadherence can be addressed with proper periodic counseling and motivation of patients and their family members. Adherence to highly active antiretroviral therapy (HAART) could delay the progression of this lethal disease and minimize the risk of developing drug resistance.     

Severity of Outcomes Associated to Illnesses Funded by GFATM Initiative and Socio Demographic and Economic Factors Associated with HIV/AIDS,TB and Malaria Mortality in Kinshasa Hospitals,DRC

Background

For the past decades, developing countries have received considerable support to fight infectious illnesses in their homelands. This global effort has tremendously reduced case fatality rates associated with illnesses such as HIV/AIDS, tuberculosis and malaria in many countries. However, this information is still missing in some developing countries, hindering international effort for control programs; we designed this study in effort to close this gap.

Methods

Data on 23,487 inpatients from Kinshasa hospitals were gathered and analyzed using EpiData and SPSS. Major illnesses affecting inpatients were identified; mortality and case fatality rates associated with each such illness were estimated. Case fatality rates associated with each illness were compared between consecutive years. Socio demographic and economic factors associated with mortality due to HIV/AIDS, TB and malaria were investigated using logistic regression.

Results

The outstanding findings were that case fatality rates associated with major illnesses were relatively higher in 2008 than in the previous year; inpatients hospitalized for HIV/AIDS, TB and malaria in 2008 were more likely to die than those hospitalized in the previous year. Low socioeconomic status inpatients hospitalized for malaria, HIV/AIDS or TB were more likely to die than high socioeconomic status inpatients (AOR 0.29, 95% CI 0.22–0.40; AOR 0.20, 95%CI0.12–0.33; AOR 0.33, 95%CI 0.21–0.53), even though both groups presumably had access to free life-saving treatment and care.

Conclusion

These results indicate that while improvement in health indicators greatly depends on funds availability and sustainability, these alone might not be enough in resource poor developing countries. Other factors, i.e., population SES also need to be addressed before needed changes may occur.     

Notified tuberculosis among Singapore residents by ethnicity, 2002–2011

Setting:

The National Tuberculosis Programme in Singapore where, among resident cases, higher tuberculosis (TB) rates have been reported in ethnic Malays.

Objective:

To describe the socio-demographic and clinical characteristics of resident TB cases by ethnicity, and to assess whether Malays differ from other groups in terms of the above parameters.

Design:

Cross-sectional review of records from the tuberculosis registry’s electronic database.

Results:

Among 15 622 resident cases notified, 72.2% were Chinese, 18.7% Malay, 5.8% Indian and 2.9% were from other minorities. Compared to other ethnicities, Malays were more likely to be incarcerated at the time of notification (odds ratio [OR] 3.70, 95%CI 3.03–4.52) and clustered at the same residential address (OR 1.65, 95%CI 1.44–1.89), but were less likely to be aged ≥65 years (OR 0.61, 95%CI 0.54–0.70) or to reside in high-cost housing (OR 0.11, 95%CI 0.07–0.17). In terms of disease characteristics, more Malays had diabetes mellitus (OR 1.54, 1.37–1.73), a highly-positive acid-fast bacilli smear (OR 1.64, 95%CI 1.47–1.83) and cavitary disease on chest X-ray (OR 1.41, 95%CI 1.28–1.55).

Conclusion:

Compared to other ethnicities, reported TB cases among Malays were more severe and were likely to be more infectious. Increased vigilance in case management and contact investigations, as well as an improvement in the socio-economic conditions of this community, are required to reduce TB rates in this ethnic group.     

Malnutrition: Prevalence and its associated factors in People living with HIV/AIDS,in Dilla University Referral Hospital

Background

Literatures on prevalence and factors associated with malnutrition among peoples living with HIV/AIDS are limited in Ethiopia and not well documented either. The proper implementation of nutritional support and its integration with the routine highly active antiretroviral therapy package demands a clear picture of the magnitude and associated factors of malnutrition. The objective of this study is, therefore, to assess the prevalence and factors associated with malnutrition among peoples living with HIV/AIDS.

Methods

Institution based cross sectional study was conducted in Dilla University referral Hospital including adult HIV patients who were in highly active anti retroviral therapy. Interview administered questionnaires were used to collect data on socio demographic factors. Besides, HIV related clinical information was extracted from anti retro viral therapy data base and clinical charts. The nutritional status of the patients was determined by Body Mass Index (BMI) where BMI < 18kg/m² was defined as malnutrition according to World Health Organization (WHO). Binary logistic regression was used to assess association between different risk factors and malnutrition. Confidence interval of 95% was considered to see the precision of the study and the level of significance was taken at α <0.05.

Results

A total of 520 patients were included in the analysis. The overall prevalence of malnutrition was 12.3% (95% CI 9.5–15.0). After full control of all variables; unemployment (OR = 3.61, 95% CI: 3.6 − 7.76), WHO clinical stage four (OR = 12.9, 95% CI: 2.49− 15.25), gastrointestinal symptoms (OR = 5.3, 95% CI: 2.56 − 10.78) and previous (one) opportunistic infection (OR = 3.1, 95% CI 2.06 − 5.46), and two & above previous opportunistic infections (OR = 4.5, 95% CI: 3.38 − 10.57) were significantly associated with malnutrition. However, moderately poor economic condition was found to be protective factor for malnutrition (OR = 0.4, 95% CI: 0.14 − 0.95).

Conclusion

Unemployment, WHO clinical AIDS stage four, one & more number of previous opportunistic infections and gastrointestinal symptoms were found to be important risk factors for malnutrition among People Living with HIV/AIDS. From this study it has been learnt that nutritional programs should be an integral part of HIV/AIDS continuum of care. Furthermore, it needs to improve household income of PLHIV with employment opportunity and to engage them in income generating activities as well.     

Comparative analysis of non-adherence to medication treatment for systemic arterial hypertension in urban and rural populations

OBJECTIVE:

to evaluate the indexes and the main factors associated with non-adherence to medication treatment for systemic arterial hypertension between urban and rural areas.

METHOD:

analytical study based on an epidemiological survey with a sample of 247 hypertensive residents of rural and urban areas, with application of a socio-demographic and economic questionnaire, and treatment adherence assessment. The Pearson''s Chi-square test was used and the odds ratio (OD) was calculated to analyze the factors related to non-adherence.

RESULTS:

the prevalence of non-adherence was 61.9% and it was higher in urban areas (63.4%). Factors significantly associated with non-adherence were: male gender (OR=1.95; 95% CI 1.08-3.50), age 20-59 years old (OR=2.51; 95% CI 1.44-4.39), low economic status (OR=1.95; 95% CI 1.09-3.47), alcohol consumption (OR=5.92, 95% CI 1.73-20.21), short time of hypertension diagnosis (OR=3.07; 95% CI 1.35-6.96) and not attending the health service for routine consultations (OR=2.45; 1.35-4.42).

CONCLUSION:

the socio-demographic/economic characteristics, lifestyle habits and how to relate to health services were the factors that presented association with non-adherence regardless of the place of residence.     

Evaluation of Community-Based Trichiasis Surgery in Northwest Ethiopia

Background

Surgery to correct trachomatous trichiasis (TT) is recommended to prevent blindness caused by trachoma. This study evaluated the outcomes of community-based trichiasis surgery with absorbable sutures, conductd in Amhara Regional State, Ethiopia.

Methods

A simple random sample of 431 patients was selected from surgical campaign records of which 363 (84.2%) were traced and enrolled into the study. Participants were interviewed and examined for trichiasis recurrence, complications of TT surgery and corneal opacity. Multilevel logistic regression models were used to explore the associations between trichiasis recurrence, corneal opacity and explanatory variables at the eye level.

Results

The prevalence of trichiasis recurrence was 9.4% (95% Confidence Interval [CI] 6.6–12.8) and corneal opacity was found in 14.3% (95% CI 10.9–18.3) of the study participants. The proportion of participants with complications of TT surgery was: granuloma 0.6% (95% CI 0.1–2.0); lid closure defects 5.5% (95% CI 3.4–8.4) and lid notching 16.8% (95% CI 13.1–21.1). No factors were identified for trichiasis recurrence. Corneal opacity was associated with increased age (Ptrend=0.001), more than 12 months post surgery (OR=2.7; 95%CI 1.3–5.6), trichiasis surgery complications (OR=2.9; 95%CI 1.4–5.9) and trichiasis recurrence (OR=2.5; 95%CI 1.0–6.3).

Conclusion

Prevalence of recurrent trichiasis and granuloma were lower than expected but higher for lid closure defects and lid notching. The majority of the participants reported satisfaction with the trichiasis surgery they had undergone. The findings suggest that recurrence of trichiasis impacts on the patients'' risk of developing corneal opacity but longitudinal studies are required to confirm this.     

Willingness to participate in trials and to be vaccinated with new tuberculosis vaccines in HIV-infected adults

Background:

New tuberculosis (TB) vaccines are required to meet global targets for TB control.

Objectives:

To determine willingness to participate (WTP) in new TB vaccine trials, willingness to be vaccinated with a newly licensed TB vaccine and associated factors among human immunodeficiency virus (HIV) infected persons.

Setting:

Two primary care clinics in South Africa.

Design:

Cross-sectional study design. Participants were asked about WTP and willingness to be vaccinated. Demographic, clinical, knowledge of TB and perception of risk information were collected. Log binomial regression was used to determine associated factors.

Results:

A total of 827 participants were included in the analysis: 80.4% female, 72.2% on antiretroviral therapy, median age 35 years (interquartile range [IQR] 29–42 years), CD4 count 523 cells/µl (IQR 427–659 cells/µl). WTP and willingness to be vaccinated were high, at 84.5% and 92.6%, respectively. WTP was associated with knowledge about TB (prevalence ratio [PR] 1.10, 95% confidence interval [CI] 1.03–1.17) and perception of risk (PR 1.07, 95%CI 1.01–1.13). Willingness to be vaccinated was associated with employment (PR 1.04, 95%CI 1.01–1.08) and perception of risk (PR 1.05, 95%CI 1.01–1.09).

Conclusions:

There was high WTP in TB vaccine trials and willingness to be vaccinated among HIV-infected patients with good TB knowledge and high perceived risk of contracting TB.     

Why do child contacts of multidrug-resistant tuberculosis not come to the assessment clinic?

Background:

Local policy advises that children exposed to multidrug-resistant tuberculosis (MDR-TB) should be assessed in a specialist clinic. Many children, however, are not brought for assessment.

Methods:

Focus group discussion was used to design appropriate questionnaires. From 1 September 2011, the first 50 children referred to the specialist paediatric MDR-TB clinic, Cape Town, South Africa, and who attended their clinic appointment, were recruited. The first 50 children who were referred but who did not attend were concurrently identified, traced and recruited. Differences in group characteristics were compared.

Results:

The median age of the children was 35 months: 48 (48%) were boys, 4 (4%) were human immunodeficiency virus infected and 47 (47%) were of coloured ethnicity. Factors significantly associated with non-attendance at the MDR-TB clinic were: Coloured ethnicity (OR 2.82, 95%CI 1.21–6.59, P = 0.01), the mother being the source case (OR 3.78, 95%CI 1.29–11.1, P = 0.02), having a smoker resident in the house (OR 2.37, 95%CI 1.01–5.57, P = 0.04), the time (P = 0.002) and cost (P = 0.03) required to get to the specialist clinic, and fear of infection whilst waiting to be seen (OR 2.45, 95%CI 1.07–5.60, P = 0.03).

Conclusions:

Reasons for non-attendance at paediatric MDR-TB clinic appointments are complex and are influenced by demographic, social, logistical and cultural factors.     

Disseminated bacille Calmette�CGu��rin disease in HIV-infected South African infants

Objective

To determine the population-based incidence of disseminated bacille Calmette–Guérin (BCG) disease in HIV-infected infants (aged ≤ 1 year) in a setting with a high burden of tuberculosis and HIV infection coupled with a well-functioning programme for the prevention of HIV infection in infants.

Methods

The numerator, or number of new cases of disseminated BCG disease, was derived from multicentre surveillance data collected prospectively on infants with a confirmed HIV infection during 2004–2006. The denominator, or total number of HIV-infected infants who were BCG-vaccinated, was derived from population-based estimates of the number of live infants and from reported maternal HIV infection prevalence, vertical HIV transmission rates and BCG vaccination rates.

Findings

The estimated incidences of disseminated BCG disease per 100 000 BCG-vaccinated, HIV-infected infants were as follows: 778 (95% confidence interval, CI: 361–1319) in 2004 (vertical HIV transmission rate: 10.4%); 1300 (95% CI: 587–2290) in 2005 (transmission rate: 6.1%); and 1013 (95% CI: 377–1895) in 2006 (transmission rate: 5.4%). The pooled incidence over the study period was 992 (95% CI: 567–1495) per 100 000.

Conclusion

Multicentre surveillance data showed that the risk of disseminated BCG disease in HIV-infected infants is considerably higher than previously estimated, although likely to be under-estimated. There is an urgent need for data on the risk–benefit ratio of BCG vaccination in HIV-infected infants to inform decision-making in settings where HIV infection and tuberculosis burdens are high. Safe and effective tuberculosis prevention strategies are needed for HIV-infected infants.     

Surveillance of anti-tuberculosis drug resistance in the world: an updated analysis, 2007-2010

Objective

To present a global update of drug-resistant tuberculosis (TB) and explore trends in 1994–2010.

Methods

Data on drug resistance among new and previously treated TB patients, as reported by countries to the World Health Organization, were analysed. Such data are collected through surveys of a representative sample of TB patients or surveillance systems based on routine drug susceptibility testing. Associations between multidrug-resistant TB (MDR-TB) and human immunodeficiency virus (HIV) infection and sex were explored through logistic regression.

Findings

In 2007–2010, 80 countries and 8 territories reported surveillance data. MDR-TB among new and previously treated cases was highest in the Russian Federation (Murmansk oblast, 28.9%) and the Republic of Moldova (65.1%), respectively. In three former Soviet Union countries and South Africa, more than 10% of the cases of MDR-TB were extensively drug-resistant. Globally, in 1994 to 2010 multidrug resistance was observed in 3.4% (95% confidence interval, CI: 1.9–5.0) of all new TB cases and in 19.8% (95% CI: 14.4–25.1) of previously treated TB cases. No overall associations between MDR-TB and HIV infection (odds ratio, OR: 1.4; 95% CI: 0.7–3.0) or sex (OR: 1.1; 95% CI: 0.8–1.4) were found. Between 1994 and 2010, MDR-TB rates in the general population increased in Botswana, Peru, the Republic of Korea and declined in Estonia, Latvia and the United States of America.

Conclusion

The highest global rates of MDR-TB ever reported were documented in 2009 and 2010. Trends in MDR-TB are still unclear in most settings. Better surveillance or survey data are required, especially from Africa and India.     

Cohort study of institutionalized elderly people: fall risk factors from the nursing diagnosis

Objective:

to determine the incidence of falls in elderly residents of long-stay institutions of the Federal District, to identify the aspects involved in the falls, in terms of risk factors, from the application of scales and the Taxonomy II of NANDA-I, and to define the level of accuracy with its sensitivity and specificity for application in the clinical nursing practice.

Method:

this was a cohort study with the evaluation of 271 elderly people. Cognition, functionality, mobility and other intrinsic factors were evaluated. After six months, the elderly people who fell were identified, with significance analysis then performed to define the risk factors.

Results:

the results showed an incidence of 41%. Of the 271 patients included, 69 suffered 111 episodes of falls during the monitoring period. Risk factors were the presence of stroke with its sequelae (OR: 1.82, 95% CI 1.01 - 3.28, p=.045), presenting more than five chronic diseases (OR: 2.82, 95% CI 1.43 - 5.56, p=.0028), foot problem (OR: 2.45, 95% CI 1.35 - 4.44, p=.0033) and motion (OR: 2.04, 95% CI 1.15 - 3.61, p=.0145).

Conclusion:

the taxonomy has high validity regarding the detection of elderly people at risk of falling and should be applied consistently in the clinical nursing practice.     

Human intestinal schistosomiasis in communities living near three rivers of jimma town, South Western ethiopia

Background

Schistosoma mansoni is one of the parasites with high public and medical importance in Ethiopia. However, information is scarce about S. mansoni epidemiology in people living with higher risk of infection in Jimma town. This study was designed to determine point prevalence, intensity and risk factors of S. mansoni infection among residents nearby three rivers of Jimma town and assess the rate of Biomphalaria species shading cercariae from January to April, 2007.

Methods

A cross-sectional study was conducted in communities residing nearby three rivers of Jimma town. Structured questionnaires were used to collect data on socio- demographic and behavioral risk factors. After physical examination, stool samples were collected from 517 study participants and processed with Kato-Katz technique for microscopic examination and quantification of egg load. Snails were collected for identification of Biomphalaria species and then checked for cercarial shading.

Results

The prevalence of S. mansoni was 26.3 % with intensity ranging 24 to 936 eggs per gram of stool. Participants in the age group 10–19 years, OR = 2.19 (95% CI; 1.10 – 4.34), and those living near the Awetu River, OR = 2.67 (95% CI; 1.06 – 6.75), had higher risk of S. mansoni infection. Moreover, water contact while crossing a river, OR = 3.77 (95% CI; 1.79 – 7.95), and swimming, OR = 2.59 (95% CI; 1.37 – 4.91, was significantly associated with infection. Biomphalaria snails collected from Chore and Awetu Rivers shaded higher rate of cercariae compared with Kito River.

Conclusion

A moderate prevalence of S. mansoni infection was shown in the study population. Infection rate among the residents correlated with rate of cercarial shading Biomphalaria snails. Treatment of targeted groups, appropriate health education and environmental measures (e.g. snail control) are needed to improve the situation.     

Risk Factors Associated with Invasive Cervical Carcinoma among Women Attending Jimma University Specialized Hospital,Southwest Ethiopia: A Case Control Study

Background

Cervical cancer is a more serious public health problem than other cancers in women in Sub-Saharan Africa in general and in Ethiopia in particular. Thus, this study assessed risk factors related to invasive cervical carcinomas in southwestern Ethiopia.

Methods

Unmatched case control study was conducted in Jimma University Specialized Hospital from April 1 to September 30, 2010. The study consisted of 60 cases (women who had cervical cancers based on histopathologic examination) and 120 controls (women with no cervical cancers). Semi-structured questionnaire was utilized for data collection. Vaginal examinations often visualized with speculum insertions were done for both cases and controls. Punch cervical biopsies were then performed for the suspected cases at Jimma University Hospital that serves about 15 million people in a catchment radius of 250 kms. Data were analyzed using SPSS version 13.0 software. Univariate and multivariate analyes were done to describe and identify independent predictors of cervical cancer.

Results

The mean ages of cases and controls were 47.7 (SD=10.8) and 35.5 (SD =10.5) years respectively. Older women (40–59 years), (OR= 4.7; 95%CI= 2.3–9.6), more than one husband (OR= 2.0; 95%CI=1.0–3.9), as well as more than one wife in lifetime, (OR= 3.0; 95% CI= 1.5–5.9), women who had more than 4 children, (OR =10.3, 95% CI= 3.6–29.0), and age greater than 25 years at first full term delivery, (OR= 8.8; 95% CI= 3.5–22.0) were statistically significant and the latter two were independently associated with invasive cervical cancer. Only 7(11.7 %) of cases and 58(48.3%) of controls ever heard of cervical cancers; however, 2(3.3%) of cases and 7(5.8%) of controls had ever had history of papaneocolous (pap) smear tests done.

Conclusion

Poor knowledge on cervical cancer was observed that required more work to be done to increase knowledge of mothers on cervical cancer and on associated risk factors. Behavioral communication activities and establishment of cervical cancer screening programs for the young could help reduce the advancement of cervical cancer particularly among the less knowledgeable, older and grand multiparous women in our parts of the world.     

Prevalence and intensity of chronic pain and self-perceived health among elderly people: a population-based study

OBJECTIVE:

to identify the prevalence and intensity of chronic pain among elderly people of the community and to analyze associations with the self-perceived health status.

METHOD:

cross-sectional study with a populational sample (n=934), conducted through household interviews in the city of Goiânia, Brazil. The intensity of chronic pain (existing for 6 months or more) was measured using a numerical scale (0-10) and the self-perceived health through a verbal scale (very good, good, fair, poor, very poor). For the statistical analysis, the absolute frequency and percentage, CI (95%), Chi-square test, Odds ratio, and regression analysis were used. Significance of 5%.

RESULTS:

The prevalence of chronic pain was 52.8% [CI (95%):49.4-56.1]; most frequently located in the lower limbs (34.5%) and lumbar region (29.5%); with high or the worst possible intensity for 54.6% of the elderly people. The occurrence of chronic pain was associated with (p<0.0001) a worse self-perception of health (OR=4.2:2.5-7.0), a greater number of chronic diseases (OR=1.8:1.2-2.7), joint disease (OR=3.5:2.4-5.1) and the female gender (OR=2.3:1.7-3.0). A lower intensity of chronic pain was associated with a better self-perception of health (p<0.0001).

CONCLUSION:

the majority of the elderly people of the community reported chronic pain, of a severe intensity, and located in areas related to movement activities, thus influencing the morbidity and mortality of this population.
