The influence of interviewers on survey responses among female sex workers in Zambia. in [in]BMC Medical Research Methodology 19(1):60.

interviewers can substantially affect self-reported data. This may be due to random variation in interviewers' ability to put respondents at ease or in how they frame questions. It may also be due to systematic differences such as social distance between interviewer and respondent (e.g., by age, gender, ethnicity) or different perceptions of what interviewers consider socially desirable responses. Exploration of such variation is limited, especially in stigmatized populations. We found substantial interviewer-level effects for prevalence and associational outcomes among Zambian FSWs, particularly for sensitive questions. Our findings highlight the importance of careful training and response monitoring to minimize inter-interviewer variation, of considering social distance when selecting interviewers and of evaluating whether interviewers are driving key findings in self-reported data.

The influence of interviewers on survey responses among female sex workers in Zambia in B<C Medical Research Methodology

Interviewers can substantially affect self-reported data. This may be due to random variation in
interviewers’ ability to put respondents at ease or in how they frame questions. It may also be due to systematic
differences such as social distance between interviewer and respondent (e.g., by age, gender, ethnicity) or different
perceptions of what interviewers consider socially desirable responses. Exploration of such variation is limited,
especially in stigmatized populations.

Data was analyzed from a randomized controlled trial of HIV self-testing amongst 965 female sex workers
(FSWs) in Zambian towns. In the trial, 16 interviewers were randomly assigned to respondents. Hierarchical
regression models were used to examine how interviewers may both affect responses on more and less sensitive topics, and confound associations between key risk factors and HIV self-test use.

Substantial interviewer-level effects for prevalence and associational outcomes among Zambian
FSWs were found, particularly for sensitive questions. The findings highlight the importance of careful training and response monitoring to minimize inter-interviewer variation, of considering social distance when selecting interviewers and of evaluating whether interviewers are driving key findings in self-reported data.

"Every Newborn-BIRTH" protocol: observational study validating indicators for coverage and quality of maternal and newborn health care in Bangladesh, Nepal, and Tanzania in Journal of Global Health

To achieve Sustainable Development Goals and Universal Health Coverage, programmatic data are essential. The Every Newborn Action Plan, agreed by all United Nations member states and >80 development partners, includes an ambitious Measurement Improvement Roadmap. Quality of care at birth is prioritized by both Every Newborn and Ending Preventable Maternal Mortality strategies, hence metrics need to advance from health service contact alone to content of care.

EN-BIRTH is an observational study including >20000 facility births in three countries (Tanzania, Bangladesh, and Nepal) to validate selected indicators. Direct clinical observation will be compared with facility register data and a pre-discharge maternal recall survey for indicators including uterotonic administration, immediate newborn care, neonatal resuscitation, and Kangaroo mother care. 

This is the first large, multi-country study validating facility-based routine data compared to direct observation for maternal and newborn care, designed to provide evidence to inform selection of a core list of indicators recommended for inclusion in national DHIS2. Availability and use of such data are fundamental to drive progress towards ending the annual 5.5 million preventable stillbirths, maternal and newborn deaths.

People-Centered Innovations in Data Collection: The Oregon Experience in Am J Public Health

The ongoing evolution of both theory and practice in public health is both necessary and welcome given the highly interdisciplinary nature of the field. At the theoretical level, the expansion of frameworks to include multilevel thinking (which builds on the social ecological framework) and life course perspective is broadening our thinking and improving our science with respect to the factors that create health or prohealth conditions.

In this issue, a group of articles explore innovations in public health practice, with an emphasis on innovative research methods in health promotion.

Improved performance of district health systems through implementing health center clinical and administrative standards in the Amhara region of Ethiopia in BMC Health Services Research

Standards represent benchmarks against which improvements can be measured. In 2016, the Federal Ministry of Health developed and endorsed a set of standards entitled the Ethiopian Health Center Reform Implementation Guidelines (EHCRIGs). This study aims to assess the effects of planned interventions on performance and quality of services in primary health care units (PHCUs).

The implementation of the standards has garnered significant improvements in performance at the primary health care level. Therefore, continuing the initiated strengthening of health system performance against the standards and evaluation of the quality of primary health services is recommended.

The Value of Tailoring Vial Sizes to Populations and Locations in Vaccine, 2018.12.10

Frequently, a country will procure a single vaccine vial size, but the question remains whether tailoring the use of different size vaccine vial presentations based on populations or location characteristics within a single country could provide additional benefits, such as reducing open vial wastage (OVW) or reducing missed vaccination opportunities. Using the Highly Extensible Resource for Modeling Supply Chains (HERMES) software, they built a simulation model of the Zambia routine vaccine supply chain and looked at measles-rubella (MR) vials.

It was found that replacing 10-dose MR with 5-dose MR vials everywhere led to the largest reduction in MR open vial wastage (OVW), and improving MR availability by 1%. It was concluded that in Zambia, tailoring 5-dose MR vials to rural health facilities or by average session size results in the highest total vaccine availability compared to all other scenarios by reducing open vial wastage without increasing cold chain utilization.

Measurement and interpretation of hemoglobin concentration in clinical and field settings: A narrative review in Annals of the New York Academy of Sciences, 2019 Jan 16

Anemia affects over 800 million women and children globally. Defined as a limited or insufficient functional red blood cell supply in peripheral blood, anemia causes a reduced oxygen supply to tissues and can have serious health consequences for women and children. Hemoglobin (Hb) concentration is most commonly measured for anemia diagnosis. Methods to measure Hb are usually invasive (requiring a blood sample); however, advances in diagnostic and clinical chemistry over the past decade have led to the development of new noninvasive methods. Accurate diagnosis at the individual level is important to identify individuals who require treatment. At the population level, anemia prevalence estimates are often the impetus for national nutrition policies or programs. Thus, it is essential that methods for Hb measurement are sensitive, specific, accurate, and reproducible. The objective of this review is to describe the basic principles, advantages, limitations, and quality control issues related to methods of Hb measurement in clinical and field settings. There is also discussion of other biomarkers and tests that can help to determine the severity and underlying causes of anemia.

It was found that there are many established and emerging methods to measure Hb concentration, each with their own advantages, limitations, and factors to consider before use.

PrEP Awareness in the Context of HIV/AIDS Conspiracy Beliefs Among Black/African American and Hispanic/Latino MSM in Three Urban US Cities in Journal of Homosexuality, January 11: 1-11, 2019.

HIV conspiracy beliefs and PrEP awareness were examined in a convenience sample of minority MSM. Participants in three cities completed a behavioral self-assessment on sociodemographics, PrEP awareness, and HIV/AIDS conspiracy beliefs. HIV/AIDS conspiracy beliefs were more common among Black than Latino MSM, and among younger men than older men. PrEP awareness co-occurred with conspiracy belief less than with non-belief, persisting in multivariable regression. This relationship suggests that current HIV care and prevention messaging is either inaccessible or not credible to some minority subpopulations.

Predictors of early initiation of breastfeeding among Zimbabwean women: secondary analysis of ZDHS 2015 in Maternal Health, Neonatology and Perinatology, Vol. 5, Issue 2

The World Health Organization recommends initiation of breastfeeding within the first hour of delivery. Early initiation is beneficial for both the mother and baby. Previous Zimbabwe Demographic and Health Surveys (ZDHS) have shown reduction in early initiation of breast feeding from 68% (2005/06) to 58% (2015). This study sought to investigate factors associated with early initiation of breast feeding among women aged 15–49 years in Zimbabwe. 

Early initiation of breast feeding in Zimbabwe is mainly associated with residing in the rural areas and multiparity. The 78% rate of early initiation of breastfeeding was contrary to the 58% reported in the ZDHS findings. Interventions targeting an improvement in early initiation of breastfeeding must aim at women who deliver by cesarean section, women with babies of abnormal birth weight, primi-parous women and women residing in rural areas.
