Risk Factors for Kala-Azar in Bangladesh

Since 1990, South Asia has experienced a resurgence of kala-azar (visceral leishmaniasis). To determine risk factors for kala-azar, we performed cross-sectional surveys over a 3-year period in a Bangladeshi community. By history, active case detection, and serologic screening, 155 of 2,356 residents had kala-azar with onset from 2000 to 2003. Risk was highest for persons 3–45 years of age, and no significant difference by sex was seen. In age-adjusted multivariable models, 3 factors were identified: proximity to a previous kala-azar patient (odds ratio [OR] 25.4, 95% confidence interval [CI] 15–44 within household; OR 3.2 95% CI 1.7–6.1 within 50 m), bed net use in summer (OR 0.7, 95% CI 0.53–0.93), and cattle per 1,000 m2 (OR 0.8, 95% CI 0.70–0.94]). No difference was seen by income, education, or occupation; land ownership or other assets; housing materials and condition; or keeping goats or chickens inside bedrooms. Our data confirm strong clustering and suggest that insecticide-treated nets could be effective in preventing kala-azar

Association between Acculturation and Breastfeeding among Hispanic Women: Data from the Pregnancy Risk Assessment and Monitoring System

Background: Breastfeeding rates are typically higher among Hispanic women; however, they vary by acculturation status in that those more acculturated are less likely to breastfeed than those who are less acculturated. This study examined the association between acculturation and breastfeeding behaviors using population-based data. Methods: Data (N = 8942) from the Pregnancy Risk Assessment Monitoring System (PRAMS) were used for analysis. Acculturation status was determined using self-reported Hispanic ethnicity and the language in which the women responded to the PRAMS survey, either English or Spanish. Hispanic women who responded to the survey in Spanish were categorized as less acculturated than those who responded in English. Breastfeeding indicators used were: initiation, duration to ≥ 10 weeks, and exclusive breastfeeding to ≥ 10 weeks. Results: The prevalence rates of breastfeeding initiation, duration, and exclusive breastfeeding to ≥ 10 weeks were significantly higher among less acculturated than among highly acculturated. More acculturated were less likely to initiate breastfeeding (prevalence ratio [PR] = 0.88; 95% CI, 0.86-0.90), less likely to breastfeed ≥ 10 weeks (PR = 0.77; 95% CI, 0.72-0.82), and less likely to report exclusive breastfeeding to ≥ 10 weeks (PR =,0.70; 95% CI, 0.58-0.85). The relationship between breastfeeding continuation and acculturation persisted after adjusting for covariates in that more acculturated were less likely to breastfeed to ≥ 10 weeks (adjusted prevalence ratio [APR] = 0.81; 95% CI, 0.75-0.87), as did the relationship between exclusivity and acculturation; more acculturated were less likely to report exclusive breastfeeding (APR = 0.69; 95% CI, 0.55-0.87). Conclusions: Breastfeeding promotion efforts must include culturally/linguistically supportive services to assure that women are able to make optimal infant feeding decisions

Birth outcomes of intended pregnancies among women who used assisted reproductive technology, ovulation stimulation, or no treatment

Objective: To study birth outcomes among live born infants conceived by women who used infertility treatment. Design: Population-based surveillance of women who recently delivered a live infant. Setting: The birth outcomes among infants whose mothers used assisted reproductive technology (ART) or ovulation stimulation medications alone were compared with the outcomes of infants conceived without treatment. Patient(s): Stratified random sample of women who were attempting conception and gave birth to a live infant in six US states (n = 16,748). Intervention(s): Assisted reproductive technology and ovulation stimulation. Main Outcome Measure(s): Adjusted odds ratios for perinatal outcomes. Result(s): The prevalence of infertility treatment use overall among women attempting conception was 10.9% (5.4% ART procedures, 5.5% ovulation stimulation medications). Singletons of mothers who received ART procedures were more likely to be born with low birthweight, preterm, and small for gestational age (SGA) than singleton infants conceived without treatment. Singleton infants of mothers who used ovulation stimulation medications alone were more likely to be SGA than singleton infants conceived without treatment. No differences were found between ART and no treatment twin infants. Conclusion(s): Among singleton infants, ART is associated with decreased fetal growth, decreased gestational length, and SGA; ovulation stimulation alone is associated with SGA

Percentage of current tobacco smoking students receiving help or advice to quit: Evidence from the Global Youth Tobacco Survey, 56 countries, 2012–2015

Introduction We assessed self-reported receipt of help or advice to stop smoking among current tobacco smoking students enrolled in school. Methods Using cross-sectional data collected between 2012–2015 from the Global Youth Tobacco Survey (GYTS), and representing the latest year for which data were collected, we calculated prevalence of receipt of help or advice to stop smoking among current tobacco smoking students aged 13–15 years from 56 countries. The sources of help or advice assessed in the GYTS were: 1) from a program or professional, 2) from a friend, and 3) from a family member. Overall response rates ranged from 60.3% in Nicaragua to 99.2% in Sudan. The analytic sample size ranged from 55 in Gabon to 950 in Bulgaria. Results In 53 of the 56 assessed countries, more than half of current tobacco smoking students received help or advice to quit from either a program or professional, friend, or family member (range=39.9% San Marino to 96.9% Timor-Leste). From a friend or family member only, the range was 37.2% Bahamas to 69.9% Montenegro, and from a program or professional only, the range was 3.7% Latvia to 34.2% Togo. Conclusions Family and friends are the most common sources of help or advice to quit smoking among current tobacco smoking students in the GYTS countries assessed, while programs and professionals were the least common. The use of evidence-based measures is critical to prevent and reduce tobacco use among youth and to ensure they are receiving appropriate help or advice to quit

Monitoring seasonal influenza vaccination coverage among pregnant women in the United States

This report describes surveillance systems used for assessing influenza vaccination coverage among pregnant women in the United States. Coverage estimates and factors associated with maternal vaccination are reviewed for internet panel surveys of pregnant women and the Pregnancy Risk Assessment Monitoring System (PRAMS); new estimates are reported from the Behavioral Risk Factor Surveillance System (BRFSS) and Internet panel surveys. Influenza vaccination coverage among pregnant women improved from 11% during the 2001-2002 influenza season to approximately 38% measured by BRFSS and 50% measured by Internet panel surveys during the 2010-2011 influenza season. Coverage varied by state, ranging from 26% to 68% among the states participating in PRAMS in 2009-2010. Provider recommendation increased a woman’s likelihood of vaccination nearly 6-fold. Despite increases in influenza vaccination coverage among pregnant women, approximately half remain unvaccinated. Continued efforts are needed to ensure pregnant women receive recommendations and offers of vaccination from their health care providers

Immunization coverage of children in a semi-urban village panchayat in Nepal, 1985

This research project, funded by the Yale International Committee and in cooperation with UNICEF, Nepal, used a questionnaire to survey and assess the immunization status of children 3 years or younger in a semi-urban panchayat. Mothers of children ranging in age from less than 1 month to 3 years were questioned both about immunization status of their children and their own use of health care and specific sources of information. 54% (124/228) of the children had received at least one vaccine and only 4% (10/228) had full coverage with the recommended vaccines (3 doses of DPT and TOPV, one dose of measles and BCG). The mean number of vaccinations for males was significantly greater than that for females (2.12 vs 1.39, P = 0.007, t = 2.80). Male children were twice as likely to have received vaccines as females (76/122, 62% vs 48/106, 45%; Odds Ratio = 2.00). Children born at a hospital were more likely than those born at home to have been vaccinated (23/34, 68% vs 101/194, 52%; P = 0.05, x2 = 12.52, d.f. = 2). Most mothers obtained health information from neighbors (38%), radio (22%), or health workers (18%), and 85% of the children were born at home; the majority (164/228, 72%) of the women received assistance during childbirth, 28% of the total reported self delivery. More than 70% of the women felt that vaccinations were good preventive measures. The study results suggest that health education about immunization efforts should be focused on women and these efforts should be intensified.Nepal immunization coverage epidemiology children

Sustainability of community-capacity to promote safer motherhood in northwestern Tanzania: What remains?

Objective. To examine the remains of the Community-Based Reproductive Health Project (CBRHP) implemented by CARE-Tanzania to address high maternal mortality in two rural districts. Methods. In early 2007, data were collected from 29 villages and used to assess sustainability of emergency transport systems, retention of village health workers (VHWs), and their potential impact on maternal health. Surveillance data from the Ministry of Health were reviewed to assess changes in prenatal and service use indicators. Results. From 2001 through 2006, the CBRHP-trained VHWs have continued to provide education and referrals to women in their communities including prenatal and emergency obstetric care; six villages with emergency transport systems have continued for more than 5 years providing free or low-cost transport to health facilities. Selected maternal and infant health indicators, such as early prenatal care, identification of pregnancy-related danger signs, and data on maternal and infant outcomes, improved in the two targeted districts over time. Conclusions. The two components of CBRHP, work of VHWs and community-financing for emergency transport systems in six villages, have continued. Both of these promote maternal health and linkages with the health delivery systems. Surveillance data show changes in maternal health indicators that were targeted by the district-wide CBRHP interventions. Programs such as CBRHP, with focus on capacity-building and empowerment, can assist in mobilizing the formal and informal systems in communities, components of which may be sustained over time

State-specific prevalence of selected chronic disease-related characteristics--Behavioral Risk Factor Surveillance System, 2001.

PROBLEM: High-risk behaviors and lack of preventive care are associated with higher rates of morbidity and mortality in the United States. Without continued monitoring of these factors, state health departments would have difficulty tracking and evaluating progress toward Healthy People 2010 and their own state objectives. Monitoring chronic disease-related behaviors is also key to developing targeted education and intervention programs at the national, state, and local levels to improve the health of the public. REPORTING PERIOD COVERED: Data collected in 2001 are compared with data from 1991 and 2000, and progress toward Healthy People 2010 targets is assessed. DESCRIPTION OF SYSTEM: The Behavioral Risk Factor Surveillance System (BRFSS) is an ongoing, state-based, telephone survey of persons aged > or =18 years. State health departments collect the data in collaboration with CDC. In 2001, participants in data collection included all 50 states, the District of Columbia, Guam, the U.S. Virgin Islands, and the Commonwealth of Puerto Rico. BRFSS data are used to track the prevalence of chronic disease-related characteristics and monitor progress toward national health objectives related to 1) decreasing high-risk behaviors, 2) increasing awareness of medical conditions, and 3) increasing use of preventive health services. For certain national objectives, BRFSS is the only source of data. RESULTS: BRFSS data indicate changes in certain high-risk behaviors from 1991 to 2001. Among the findings are substantial increases in the prevalence of obesity among adults aged > or =20 years. Among states, prevalence of persons classified as obese in 2001 ranged from 15.5% in Colorado to 27.1% in Mississippi. From 1991 to 2001, the median prevalence for all participating states and territories increased from 12.9% to 21.6%. In 1991, no state had an obesity prevalence of > or =20%; in 2001, 37 states had a prevalence of > or =20%. Percentage increases in prevalence of obesity, from 1991 to 2001, ranged from 24.9% in the District of Columbia to 140.2% in New Mexico. In 2001, substantial variations also existed among states and territories regarding prevalence of other high-risk behaviors and awareness of medical conditions. Ranges included, for no leisure-time physical activity, 16.5% (Utah) to 49.2% (Puerto Rico); cigarette smoking, 9.6% (Virgin Islands) to 31.2% (Guam); binge drinking, 6.8% (Tennessee) to 25.7% (Wisconsin); heavy drinking, 2.5% (Tennessee) to 8.7% (Wisconsin); persons ever told they had diabetes, 4% (Alaska) to 9.8% (Puerto Rico); persons ever told they had high blood pressure, 20% (New Mexico) to 32.5% (West Virginia); and persons ever told they had high blood cholesterol, 24.8% (New Mexico) to 37.7% (West Virginia). Substantial variations also existed among states regarding prevalence of using preventive health services. Ranges included, for persons aged > or =50 years ever screened for colorectal cancer by use of sigmoidoscopy or colonoscopy, 30.5% (Virgin Islands) to 62% (Minnesota); persons aged > or =65 years who received an influenza vaccination in the past year, 36.8% (Puerto Rico) to 79% (Hawaii); persons aged > or =65 years who ever received a pneumococcal vaccination, 24.1% (Puerto Rico) to 70.9% (Oregon). In 2001, 13 states, Guam, and the U.S. Virgin Islands used the women's health module. Ranges included, for women aged > or =18 years who had a Papanicolaou (Pap) smear test in the past 3 years, 79.8% (Virgin Islands) to 89.6% (Wisconsin); women aged > or =40 years who ever had a mammogram, 71.9% (Virgin Islands) to 93% (Rhode Island); and women aged > or =40 years who had a mammogram in the past 2 years, 57.2% (Virgin Islands) to 85.1% (Rhode Island). BRFSS data in 2001 also indicated variations by sex, race or ethnicity, and age group. Greater percentages of men than women reported cigarette smoking, binge drinking, heavy drinking, and were classified as overweight; greater percentages of women reported no leisure-time physical activity. Among racial or ethnic groups, greater percentages of black non-Hispanics than other groups reported being told by a health professional they had high blood pressure and diabetes, and were classified as obese; greater percentages of white non-Hispanics than other groups reported being told they had high cholesterol. Among age groups, greater percentages of persons aged 18-24 years than those in older groups reported smoking cigarettes, binge drinking and heavy drinking; greater percentages of persons in older age groups than younger age groups reported being told they had diabetes, high blood pressure, and high blood cholesterol. Also, comparison of 2001 BRFSS data with 12 targets from Healthy People 2010 indicates that, in 2001, no state had met the targets for obesity, cigarette smoking, binge drinking, receiving a fecal occult blood test within the past 2 years, receiving annual influenza vaccinations, receiving pneumococcal vaccinations, and receiving Pap tests. Certain states had already met targets for no leisure-time activity, receiving a sigmoidoscopy or colonoscopy, having blood cholesterol checked within the past 5 years, and receiving a mammogram within the past 2 years. INTERPRETATION: BRFSS data in this report indicate that despite certain improvements, persons in a high proportion of U.S. states and territories continue to engage in high-risk behaviors and do not report making sufficient use of preventive health practices. Substantial variations (i.e., by state, sex, age group, and race/ethnicity) in prevalence of behaviors, awareness of medical conditions, and use of preventive services indicate a continued need to monitor these factors at state and local levels and assess progress toward reducing morbidity and mortality. PUBLIC HEALTH ACTIONS: BRFSS data can be used to guide public health actions at local, state, and national levels. For certain states, BRFSS is the only reliable source of chronic-disease-related, risk-behavioral data. BRFSS data enable states to design, implement, evaluate, and monitor health-promotion strategies, targeting specific high-risk behaviors among populations experiencing high burdens of disease. BRFSS data continue to be key sources for assessing progress toward both national Healthy People 2010 objectives and state health objectives.https://www.cdc.gov/mmwr/preview/mmwrhtml/ss5208a1.ht

Money Gone Up in Smoke: The Tobacco Use and Malnutrition Nexus in Bangladesh

BackgroundThe tobacco epidemic in Bangladesh is pervasive. Expenditures on tobacco may reduce money available for food in a country with a high malnutrition rate.ObjectivesThe aims of the study are to quantify the opportunity costs of tobacco expenditure in terms of nutrition (ie, food energy) forgone and the potential improvements in the household level food-energy status if the money spent on tobacco were diverted for food consumption.MethodWe analyzed data from the 2010 Bangladesh Household Income and Expenditure Survey, a nationally representative survey conducted among 12,240 households. We present 2 analytical scenarios: (1) the lower-bound gain scenario entailing money spent on tobacco partially diverted to acquiring food according to households' food consumption share in total expenditures; and (2) the upper-bound gain scenario entailing money spent on tobacco diverted to acquiring food only. Age- and gender-based energy norms were used to identify food-energy deficient households. Data were analyzed by mutually exclusive smoking-only, smokeless-only, and dual-tobacco user households.FindingsOn average, a smoking-only household could gain 269-497 kilocalories (kcal) daily under the lower-bound and upper-bound scenarios, respectively. The potential energy gains for smokeless-only and dual-tobacco user households ranged from 148-268 kcal and 508-924 kcal, respectively. Under these lower- and upper-bound estimates, the percentage of smoking-only user households that are malnourished declined significantly from the baseline rate of 38% to 33% and 29%, respectively. For the smokeless-only and dual-tobacco user households, there were 2-3 and 6-9 percentage point drops in the malnutrition prevalence rates. The tobacco expenditure shift could translate to an additional 4.6-7.7 million food-energy malnourished persons meeting their caloric requirements.ConclusionsThe findings suggest that tobacco use reduction could facilitate concomitant improvements in population-level nutrition status and may inform the development and refinement of tobacco prevention and control efforts in Bangladesh
