Descriptive epidemiological studies are of relevance, given that there are inconsistencies in the literature with regard to their nomenclature and classification. We reviewed 19 international and six national academic textbooks on epidemiology, where the main criterion was to have them available in order to undertake an in-depth review of chapters on descriptive epidemiology and study types. In 11 books, the authors prioritize analytical studies. Twelve foreign texts and two from Brazil include descriptive studies, although the majority did not specifically refer to a category with this name. We propose a classification based on the answers to research questions, including the following types of study: case report, case series, clinical cohort, prevalence study, incidence study (cohort) and descriptive ecological study. We discuss potential uses, implementation of novel data analysis methods and their relevance in health surveillance.

Características de la mortalidad por enfermedad isquémica del corazón en Costa Rica de 1970 al 2014 / Characteristics of mortality due to ischemic heart disease in Costa Rica from 1970 to 2014

Resumen Objetivo: Actualizar algunos aspectos importantes de la epidemiología descriptiva de la enfermedad isquémica del corazón (EIC) en Costa Rica durante el periodo 1970-2014. Métodos: Se obtuvieron las tasas de mortalidad por EIC en dos periodos. De 1930 al año 1969 y luego, para un análisis más específico, de 1970 al 2014, utilizando promedios móviles y quinquenios, a partir de datos del Instituto Nacional de Estadística y del Centro Centroamericano de Población, para analizarlos en relación con edad, sexo, ubicación geográfica y aporte porcentual a la mortalidad general. También se obtuvo información para determinar la carga de la enfermedad, en este caso mediante años de vida ajustados por discapacidad, años de vida perdidos y años de vida perdidos por discapacidad. Resultados: Se apreció ascenso de las tasas en la población general y con mayor empuje en la población de 35 a 74 años, hasta el quinquenio 1995-1999, a partir del cual se inicia un descenso que aparentemente se detiene durante el quinquenio 2010-2014 (ambos sexos: r = 0.9964, r2 = 0.9928, β = —2.4950, p = 0.04; hombres: r = 0.9994, r2 = 0.9988, β = —2.770, p = 0.02; mujeres: r = 0.9896, r2 = 0.9793, β = —2.4950, p = 0.07). Las tasas más altas se presentan en las provincias del centro del país. Predomina durante todo el periodo en el sexo masculino y representa en promedio el 14% de la mortalidad general. Conclusión: La mortalidad por EIC está en fase de disminución, pero el aumento de la obesidad y el sobrepeso en el país amenaza con frenar dicha tendencia, al menos durante el último quinquenio.

Abstract Objective: To update some important aspects of the descriptive epidemiology of ischemic heart (EIC) disease in Costa Rica during the period 1970-2014. Methods: EIC death rates were obtained in two periods: from 1930 to 1969 and then, for a more specific analysis, from 1970 to 2014, using moving and five-year averages, based on data from the Instituto Nacional de Estadística and the Centro Centroamericano de Población, to analyze them according to age, sex, geographical location and percentage contribution to the general mortality. Information was also obtained to determine the burden of the disease, in this case through Years of Adjusted Life for Disability, Years of Life Lost and Years of Life lost due to Disability. Results: There was a rise in rates in the general population, with greater momentum in the population from 35 to 74 years, up to the five-year period 1995-1999, after which a decline began that apparently stopped during the five-year period 2010-2014 (both sexes: r = 0.9964, r2 = 0.9928, β = -2.4950, p 0.04; men: r = 0.9994, r2 = 0.9988, β = -2.770, p = 0.02; women: r = 0.9896, r2 = 0.9793, β = -2.4950, p = 0.07). The highest rates occur in the provinces of the center of the country. It predominates during the whole period in the male sex and represents on average 14% of the general mortality. Conclusions: Mortality due to EIC is in a phase of decline but the increase in obesity and overweight in the country threatens to slow down this trend, at least during the last five years.

Checklist for reporting results using observational descriptive studies as research designs: the MInCir initiative / Lista de verificación para reporte de resultados usando estudios observacionales descriptivos como diseños de investigación: la iniciativa Mincir

Observational and descriptive studies (ODS) represent between 70 % and 80 % of the designs utilized in biomedical publications of the different scientific journals. Despite this, there are no tools to guide writers and to assist reviewers in reporting results with this type of research design. The aim of this study was to report the characteristics of a validated checklist for reporting the results using ODS as research designs in an English version. Two-stage study with qualitative methodology. In a first stage, a proposal was designed, by collecting items and domains from an extensive review of the literature. In the second, an instrument was developed by applying reduction items and domains through a panel of 45 experts comprised of clinical academics, reviewers and editors of biomedical journals, and experts in research methodology. These worked determining the validity of facade and content of the instrument. The items and domains incorporated into the final instrument were those in which over 80 % of agreement was achieved between the participants (36 of 45). In this way an instrument was created composed of 19 items, grouped into four domains. Characteristics of the design, construction and validation of a checklist that could help authors, reviewers and journal editors to write and review articles using ODS as research designs to report results was reported.

Análisis de la mortalidad por enfermedades cerebrovasculares en Costa Rica entre los años 1920-2009 / Analysis of cerebrovascular disease mortality in Costa Rica between the years 1920-2009

Resumen Objetivo Analizar la tendencia de la mortalidad por enfermedades cerebrovasculares en Costa Rica y su impacto sobre la mortalidad general entre los años 1920-2009. Métodos Se obtuvieron las tasas brutas por trienios y quinquenios del lapso estudiado, así como las tasas estandarizadas del grupo etario entre 35-74 años durante el lapso 1970-2009. Igualmente, la proporción de muertes por accidente cerebrovascular (ACV) en relación a la mortalidad general. Resultados La tendencia durante el periodo 1920-1969 fue hacia el ascenso (r = 0.82, r2 = 0.67, betha: 0.30; p = ≤ 0,00) en tanto que para el lapso 1970 ocurrió lo contrario (r = 0.42, r2 = 0.18, betha: −0.064; p = 0.01). Las tasas ajustadas para el grupo 35-74 años entre 1970-2009 descendieron en un 58.03%, siendo la tendencia estadísticamente significante para ambos sexos; varones: r2 = 0.94, betha: −0.73; mujeres: r2 = 0.97, betha: 0.95. El máximo porcentaje de la mortalidad por ACV en relación a la mortalidad general fue de 7,22 alcanzado en el quinquenio 1985-1989, descendiendo a 5.92% en el periodo 2005-2009. Conclusiones En el contexto latinoamericano, las tasas de mortalidad por ACV en Costa Rica son bajas, pero todavía constituyen un grave problema de salud pública por la gran mortalidad, morbilidad y discapacidad que ocasionan, pese a una tendencia hacia el descenso.

Abstract Objective To analyze the trend in mortality from cerebrovascular diseases in Costa Rica and its impact on overall mortality from 1920 to 2009. Methods Crude rates by triennium and quinquennium were obtained. We also obtanied age standardized rates in the age group 35-74 years during the period 1970-2009. Finally we got the death percentage from stroke in relation to overall mortality. Results The trend for the period 1920-1969 was to the upside (r=0.82, r2 =0.67, betha 0.30; P≤0.00) whereas for the period 1970 occurred otherwise (r=0.42, r2 =0.18, betha −0064; P=0.01). Adjusted for the group 35-74 years between 1970-2009 rates decreased by 58.03% was statistically significant trend for both sexes; men r2=0.94, betha: —0.73; women: r2=0.97, betha: 0.95. The maximum percentage of mortality from stroke in relation to the overall mortality was 7.22 in the period 1985-1989 reached down to 5.92% in 2005-2009. Conclusions In the Latin American context, stroke mortality rates in Costa Rica are low but still represent a serious public health problem by the high mortality, morbidity and disability that they cause, despite a downward trend.

Prevalencia de factores de riesgo de enfermedades crónicas no transmisibles en funcionarios de una institución bancaria del Uruguay / Prevalence of risk factors for chronic non communicable diseases in employees of a bank in Uruguay

Introducción: las enfermedades crónicas no transmisibles, fundamentalmente la enfermedad cardiovascular, la diabetes, el cáncer y las enfermedades respiratorias, son la primera causa de muerte en los países desarrollados y el Uruguay no escapa a esta realidad. El 30% de esas muertes se produce antes de los 60 años. Las discapacidades generadas por estas enfermedades tienen un alto impacto social y también económico. Los principales factores de riesgo conductuales para el desarrollo de estas enfermedades se relacionan con los estilos de vida: alimentación inadecuada, sedentarismo y consumo de alcohol y tabaco. Estas conductas llevan a desarrollar factores de riesgo metabólicos: obesidad, dislipemias, hipertensión arterial y prediabetes. Estos factores de riesgo pueden ser modificados, pudiéndose así prevenir las propias enfermedades no transmisibles. El lugar de trabajo está reconocido mundialmente como un marco adecuado para la promoción de salud. Objetivo: conocer la prevalencia de factores de riesgo conductuales y metabólicos en funcionarios de una institución bancaria estatal del Uruguay. Metodología: estudio descriptivo, de corte transversal, sobre una muestra probabilística de los funcionarios de una institución bancaria. Se aplicó cuestionario y se realizó antropometría. Para estudiar la asociación de los factores de riesgo se usaron tablas de contingencia y modelos de regresión logística. Resultados: se encuestaron 136 funcionarios. La distribución por sexo fue pareja, la edad promedio fue de 48 años. El 16% refirió fumar actualmente; 58% beber alcohol en forma semanal; 85% consumir fruta y verdura por debajo de las recomendaciones, y 46% no realizar actividad física. El 63% presentó sobrepeso u obesidad; 30% declaró ser hipertenso; 33% tener una dislipemia, y 12% presentar prediabetes. La obesidad abdominal se asoció con mayor riesgo de desarrollar hipertensión arterial y prediabetes. El tabaquismo y la inactividad física son menos frecuentes en esta población que en poblaciones similares en otros países de la región, sin embargo los factores de riesgo metabólicos tienen casi la misma prevalencia. Conclusiones: si bien no se trata de una población representativa del país, se hizo una comparación con la situación nacional y en relación con la población adulta uruguaya se encontró una mayor prevalencia de obesidad, hipertensión arterial, hipercolesterolemia, prediabetes, sedentarismo, consumo inadecuado de frutas y verduras y consumo de alcohol en forma semanal. A su vez, esta población presentó una prevalencia menor de tabaquismo, sobreagregado de sodio, consumo de alimentos que son una fuente de grasas trans e ingesta de bebidas azucaradas. Estos resultados representan un aporte para futuras intervenciones.

Introduction: Non communicable diseases, mainly cardiovascular disease, diabetes, cancer and respiratory diseases are the leading cause of death in developed countries and Uruguay does not escape this reality. 30% of these deaths occur before age 60 years. Disability generated by these diseases have a high social and economic impact. The main behavioral risk factors for the development of these diseases are related to lifestyle: poor diet, sedentary lifestyle, alcohol consumption and smoking. These behaviors lead to developing metabolic risk factors: obesity, dyslipidemia, hypertension and prediabetes. These risk factors can be modified, preventing the non-communicable diseases development. The workplace is recognized worldwide as a framework for health promotion. Objective: To make a situation diagnosis of the prevalence of behavioral and metabolic risk factors in employees of a state bank in Uruguay. Methodology: Descriptive, cross-sectional study, based on a random sample of the bank employees. A survey and anthropometric measures were performed. To study the association of risk factors contingency tables and logistic regression models were used. Results: 136 employees were surveyed. The gender distribution was similar, the average age was 48 years. 16% reported currently smoking, 58% drink alcohol weekly, 85% consume fruits and vegetables below the recommendations and 46% did not do physical activity. 63% had overweight or were obese, 30% reported hypertension, 33% high cholesterol and 12% prediabetes. Abdominal obesity was associated with increased risk of developing high blood pressure and prediabetes. Smoking and physical inactivity behave better in this population than in similar populations of other countries in the region, however the metabolic risk factors have almost the same prevalence. Conclusions: Even if not representative of the whole country, compared to the adult Uruguayan population this population has a higher prevalence of obesity, hypertension, hypercholesterolemia, prediabetes, sedentary lifestyle, inadequate intake of fruits and vegetables and alcohol consumption on a weekly basis. In turn, presented lower prevalence of smoking, added sodium intake and consumption of foods that contain trans fats and sugary drinks. These results represent a contribution for future interventions.

Recurrencias de malaria por Plasmodium vivax según el uso de primaquina: análisis de estudios descriptivos longitudinales / Plasmodium vivax malaria recurrence according to the use of primaquine: analysis of longitudinal descriptive studies

ANTECEDENTES: la primaquina (PQ) es el único medicamento disponible en el mercado para prevenir recurrencias del paludismo por Plasmodium vivax pero varios aspectos suyos se desconocen. OBJETIVO: comparar regímenes de PQ para prevenir recurrencias de malaria vivax. METODOLOGÍA: revisión sistemática de datos. RESULTADOS: 1. ¿Según los estudios descriptivos, la PQ es eficaz para prevenir las recurrencias del paludismo vivax? Sí. La comparación de estudios que no usaron PQ con otros que sí la aplicaron, en cualquier esquema, mostró que si no se usa PQ la recurrencia es altamente probable. 2. ¿Tienen la misma eficacia dosis diarias (mg/kg) iguales pero dosis totales diferentes? La dosis total de 75 mg es tanto o más eficaz que la de 210 mg. 3. ¿La eficacia anti-recurrencias depende del lugar donde sucede la infección? Si. Hay variación según país y región. 4. ¿La frecuencia de recurrencias depende del tiempo de seguimiento post tratamiento? La respuesta no es uniforme para todos los lugares. CONCLUSIONES: la PQ resultó eficaz para prevenir las recurrencias, pero no fue 100%. Las dosis totales de 210 y de 75 mg tuvieron igual eficacia, pero 75 mg sólo han sido evaluados en India, donde P. vivax parece ser más sensible a la PQ que en otros lugares. Parece indudable la influencia del lugar en la proporción de recurrencias, incluso con una misma dosis total. El papel del tiempo de seguimiento no resultó claro. Deben evaluarse esquemas alternativos al estándar, que tiene eficacia promedio de 90% o más.

BACKGROUND: primaquine (PQ) is the only drug available in the market to prevent Plasmodium vivax malaria recurrence, but several aspects are still unknown. OBJECTIVE: To compare PQ regimens to prevent recurrence of vivax malaria. METHODS: systematic review and meta-analysis of data. RESULTS: 1. According to descriptive studies, is PQ effective in preventing recurrence of vivax malaria? Yes. The comparison of studies that did not use PQ to others that did, using any regimen, showed that if PQ is not used, recurrence is highly likely. 2. Are equal daily doses effective (mg/kg) but total doses different? The total dose of 75 mg is equally or more effective than 210 mg. 3. Does the efficacy depend on where the infection happens? Yes. There is variation by country and region. 4. Does the recurrence rate depend on the post-treatment time follow-up? The answer is not uniform everywhere. CONCLUSIONS: Although not 100%, PQ is effective in preventing recurrence. Total doses of 210 and 75 mg are equally effective, but 75 mg alone has been evaluated in India, where P. vivax seems to respond better to PQ than elsewhere. The effect of place in the proportion of recurrences seems evident, even using the same total dose. The role of follow-up time is not clear. Although the standard regimen has an average effectiveness of 90% or more, alternative regimens should be assessed.

Association of Postpartum Maternal Morbidities with Children’s Mental, Psychomotor and Language Development in Rural Bangladesh.

Little is known from developing countries about the effects of maternal morbidities diagnosed in the postpartum period on children’s development. The study aimed to document the relationships of such morbidities with care-giving practices by mothers, children’s developmental milestones and their language, mental and psychomotor development. Maternal morbidities were identified through physical examination at 6-9 weeks postpartum (n=488). Maternal care-giving practices and postnatal depression were assessed also at 6-9 weeks postpartum. Children’s milestones of development were measured at six months, and their mental (MDI) and psychomotor (PDI) development, language comprehension and expression, and quality of psychosocial stimulation at home were assessed at 12 months. Several approaches were used for identifying the relationships among different maternal morbidities, diagnosed by physicians, with children’s development. After controlling for the potential confounders, maternal anaemia diagnosed postpartum showed a small but significantly negative effect on children’s language expression while the effects on language comprehension did not reach the significance level (p=0.085). Children’s development at 12 months was related to psychosocial stimulation at home, nutritional status, education of parents, socioeconomic status, and care-giving practices of mothers at six weeks of age. Only a few mothers experienced each specific morbidity, and with the exception of anaemia, the sample-size was insufficient to make a conclusion regarding each specific morbidity. Further research with a sufficient sample-size of individual morbidities is required to determine the association of postpartum maternal morbidities with children’s development.

Seropositivity of Toxoplasmosis in Antenatal Women with Bad Obstetric History in a Tertiary-care Hospital of Andhra Pradesh, India.

Toxoplasmosis is a well-documented cause of bad obstetric history (BOH) and a major reason of congenitally- acquired infection. The study was conducted to determine the seropositivity of toxoplasmosis in women with BOH, attending the antenatal clinic of the Mamata General Hospital, Khammam, Andhra Pradesh, India. The study subjects included 105 antenatal women with BOH and 105 antenatal women who had previous normal deliveries. A serological evaluation was carried out to determine the presence of Toxoplasma gondii-specific IgG and IgM antibodies, using commercial diagnostic kits, by the enzyme-linked immunosorbent assay method. The seropositivity for Toxoplasma was 49.52% in the study group compared to 12.38% in the control group. The difference in seropositivity was significant (p=0.00). The seroprevalence gradually increased with advancing age. Abortion (51.92%) was the commonest form of pregnancy wastage, followed by stillbirths (36.53%) and premature deliveries (7.69%). The seropositivity of toxoplasmosis was significantly higher in the study group than that in the control group, and the seropositivity played an important role in determining the foetal outcome. Considering the subclinical pattern of infection, routine serological test is recommended for all pregnant women for both IgG and IgM antibodies.

Skilled Care at Birth among Rural Women in Nepal: Practice and Challenges.

In Nepal, most births take place at home, and many, particularly in rural areas, are not attended by a skilled birth attendant. The main objectives of the study were to assess the use of skilled delivery care and barriers to access such care in a rural community and to assess health problems during delivery and seeking care. This cross-sectional study was carried out in two Village Development Committees in Nepal in 2006. In total, 150 women who had a live birth in the 24 months preceding the survey were interviewed using a structured questionnaire. The sample population included married women aged 15-49 years. Forty-six (31%) women delivered their babies at hospital, and 104 (69%) delivered at home. The cost of delivery at hospital was significantly (p<0.001) higher than that of a delivery at home. Results of univariate analysis showed that women from Brahmin-Chhetri ethnicity, women with higher education or who were more skilled, whose husbands had higher education and more skilled jobs, had first or second childbirth, and having adverse previous obstetric history were associated with institutional delivery while women with higher education and having an adverse history of pregnancy outcome predicted the uptake of skilled delivery care in Nepal. The main perceived problems to access skilled delivery care were: distance to hospital, lack of transportation, lack of awareness on delivery care, and cost. The main reasons for seeking intrapartum care were long labour, retained placenta, and excessive bleeding. Only a quarter of women sought care immediately after problems occurred. The main reasons seeking care late were: the woman or her family not perceiving that there was a serious problem, distance to health facility, and lack of transport. The use of skilled birth attendants at delivery among rural women in Nepal is very poor. Home delivery by unskilled birth attendants is still a common practice among them. Many associated factors relating to the use of skilled delivery care that were identified included age, education and occupation of women, and education and occupation of husbands. Therefore, the availability of skilled delivery care services at the community, initiation of a primary health centre with skilled staff for delivery, and increasing awareness among women to seek skilled delivery care are the best solution.

Trends in Choosing Place of Delivery and Assistance during Delivery in Nanded District, Maharashtra, India.

Delivery in a medical institution promotes child survival and reduces the risk of maternal mortality. Many initiatives under the National Rural Health Mission (NRHM) focus on increasing the institutional deliveries. This study describes the trends in choosing place of delivery in Nanded district at the end of the first phase of the mission. Key informants were interviewed to document the initiatives under NRHM implemented in the district. A cross-sectional descriptive study was conducted in 30 villages selected using one stage cluster-sampling method. A house-to-house survey was conducted in June 2009. A set of structured open-ended questionnaire was used for interviewing all women who had delivered during January 2004–May 2009. The outcomes studied were place of delivery and assistance during delivery. Analysis was done by calculating chi-square test and odds ratio. Interventions to improve the quality of health services and healthcare-seeking behaviour were implemented successfully in the district. The proportion of institutional deliveries increased from 42% in 2004 to 69% in 2009. A significant increase was observed in the proportion of institutional deliveries [60% vs 45%; χ2=173.85, p<0.05, odds ratio (OR)=1.8 (95% confidence interval (CI) 1.65-1.97)] in the NRHM period compared to the pre-NRHM period. The deliveries in government institutions and in private institutions also showed a significant rise. The proportion of deliveries assisted by health personnel increased significantly during the NRHM period [62% vs 49%; χ2=149.39; p<0.05, OR=1.73, 95% CI 1.58-1.89] However, less than 10% of the deliveries in the home (range 2-9%) were assisted by health personnel throughout the study period. There was a wide geographic variation in place of delivery among the study villages. The results showed a significant increase in the proportion of institutional deliveries and deliveries assisted by health personnel in the NRHM period. Since a less proportion of deliveries in the home is conducted by health personnel, the focus should be on increasing the institutional deliveries. Special and innovative interventions should be implemented in the villages with a less proportion of institutional deliveries.

Limited Access to Iodized Salt among the Poor and Disadvantaged in North 24 Parganas District of West Bengal, India.

Iodine deficiency is endemic in West Bengal as evident from earlier studies. This community-based, crosssectional descriptive study was conducted in North 24 Parganas district during August-November 2005 to assess the consumption of adequately-iodized salt and to ascertain the various factors that influence access to iodized salt. In total, 506 households selected using the multi-stage cluster-sampling technique and all 79 retail shops from where the study households buy salt were surveyed. The iodine content of salt was tested by spot iodine-testing kits. Seventy-three percent of the households consumed salt with adequate iodine content (≥15 ppm). Consumption of adequately-iodized salt was lower among rural residents [prevalence ratio (PR): 0.8, 95% confidence interval (CI) 0.7-0.9], Muslims (PR: 0.8, 95% CI 0.7-0.9), and households with monthly per-capita income of ≤US$ 10 (PR: 0.7, 95% CI 0.6-0.8). Those who heard and were aware of the risk of iodine-deficiency disorders and of the benefit of iodized salt were more likely to use appropriate salt (PR: 1.2, 95% CI 1.1-1.3). Those who were aware of the ban on non-iodized salt were more likely to consume adequately-iodized salt (PR: 1.1, 95% CI 1.01-1.3). The iodine content was higher in salt sold in sealed packets (PR: 2.9, 95% CI 1.8-4.8) and stored on shelves (PR: 1.6, 95% CI 1.3-2.0). Seventy-two percent of the salt samples from the retail shops had the iodine content of ≥15 ppm. The findings indicate that elimination of iodine deficiency will require targeting the vulnerable and poor population.

Infant- and Young Child-feeding Practices in Bankura District, West Bengal, India.

A community-based, cross-sectional descriptive study was conducted during June-July 2008 to assess the infant- and young child-feeding (IYCF) practices in Bankura district, West Bengal, India. In total, 647 children aged less than two years selected through revised 40-cluster sampling using the indicators of the Integrated Management of Neonatal and Childhood Illness (IMNCI) and World Health Organization. The proportions of infants with early initiation of breastfeeding (13.6%) and exclusive breastfeeding under six months (57.1%) and infants who received complementary feeding at the age of 6-8 months (55.7%) were low. Appropriate feeding as per the IMNCI protocol was significantly less among infants aged 6-11 months (15.2%) and children aged 12-23 months (8.7%) compared to infants aged less than six months (57.1%), which could be attributable to low frequency and amount of complementary feeding. The main problems revealed from the study were late initiation of breastfeeding, low rates of exclusive breastfeeding, and inappropriate complementary feeding practices.

A Descriptive Profile of Abused Female Sex Workers in India.

This descriptive study presents the profiles of abused female sex workers (FSWs) in Chennai, India. Of 100 abused FSWs surveyed using a structured questionnaire, severe forms of violence by intimate partners were reported by most (98%) respondents. Of the total sample, 76% experienced violence by clients. Sexual coercion experiences of the FSWs included verbal threats (77%) and physical force (87%) by intimate partners and forced unwanted sexual acts (73%) by clients. While 39% of the women consumed alcohol before meeting a client, 26% reported that their drunkenness was a trigger for violence by clients. The findings suggest that there is an urgent need to integrate services, along with public-health interventions among FSWs to protect them from violence. Recognition of multiple identities of women in the contexts of intimate relationships versus sex work is vital in helping women to stay safe from adverse effects on health.

Homeless in Dhaka: Violence, Sexual Harassment, and Drug-abuse.

Bangladesh has experienced one of the highest urban population growth rates (around 7% per year) over the past three decades. Dhaka, the capital city, attracts approximately 320,000 migrants from rural areas every year. The city is unable to provide shelter, food, education, healthcare, and employment for its rapidly- expanding population. An estimated 3.4 million people live in the overcrowded slums of Dhaka, and many more live in public spaces lacking the most basic shelter. While a small but growing body of research describes the lives of people who live in urban informal settlements or slums, very little research describes the population with no housing at all. Anecdotally, the homeless population in Dhaka is known to face extortion, erratic unemployment, exposure to violence, and sexual harassment and to engage in high-risk behaviours. However, this has not been systematically documented. This cross-sectional, descriptive study was conducted to better understand the challenges in the lives of the homeless population in 11 areas of Dhaka during a 13-month period from June 2007 to June 2008. A modified cluster-sampling method was used for selecting 32 clusters of 14 female and male respondents, for a sample of 896. In addition to sociodemographic details, this paper focuses specifically on violence, drug-abuse, and sexual harassment. The findings showed that physical assaults among the homeless, particularly among women, were a regular phenomenon. Eighty-three percent of female respondents (n=372) were assaulted by their husbands, station masters, and male police officers. They were subjected to lewd gestures, unwelcome advances, and rape. Male respondents reported being physically assaulted while trying to collect food, fighting over space, or while stealing, by police officers, miscreants, or other homeless people. Sixty-nine percent of the male respondents (n=309) used locally-available drugs, such as marijuana and heroin, and two-thirds of injecting drug-users shared needles. The study determined that the homeless are not highly mobile but tend to congregate in clusters night after night. Income-generating activities, targeted education, gender-friendly community police programmes, shelters and crises centres, and greater community involvement are suggested as policy and programmatic interventions to raise the quality of life of this population. In addition, there is a need to reduce high rates of urban migration, a priority for Bangladesh.

Emergency Contraception: Knowledge and Attitudes of Family Physicians of a Teaching Hospital, Karachi, Pakistan.

This study was conducted to assess the knowledge of family medicine providers and their attitudes towards emergency contraception in a teaching hospital in Karachi, Pakistan. A 21-item questionnaire containing the demographic profile of respondents and questions concerning knowledge of and attitudes towards emergency contraception was distributed among participants. In total, 45 interviews were conducted, with a response rate of 100%, with faculty physicians (33%), residents (27%), medical officers (40%), 36% male and 64% female physicians; of them, the majority (64%) were married. Although the large majority (71%) of the respondents reported considerable familiarity with emergency contraception, objective assessment revealed deficiencies in their knowledge. About 38% of the participants incorrectly chose menstrual irregularity as the most common side-effect of progestin-only emergency contraception pills, and only 33% answered that emergency contraception was not an abortifacient while 42% were unsure. Forty percent of the physicians prescribed emergency contraception in the past. The large majority (71%) of the physicians were familiar with emergency contraception, yet deficiencies in knowledge inaccuracies were identified. Barriers to its use were identified as ‘it will promote promiscuity’ (31%), religious/ethical reasons (27%), liability (40%), teratogenicity (44%), and inexperience (40%). Overall attitudes regarding emergency contraception were positive; however, most (82%) physicians were unsatisfied with their current knowledge of emergency contraception, and there was a discrepancy between perceptions of physicians and actual knowledge. Interventions providing education to family physicians regarding emergency contraception is strongly recommended.
