Cognitive testing of questions about antenatal care and nutrition interventions in southern Nepal.

Large scale surveys such as the Demographic and Health Surveys (DHS) are used to measure the coverage and quality of antenatal care (ANC)-related services. Studies have increasingly validated questions from these surveys, though few have explored respondent comprehension or associated thought processes. This study aimed to use cognitive testing and validation approaches to understand how survey respondents understand questions related to ANC-related nutrition services. The study was nested within a larger validation study in southern Nepal. Pregnant women's receipt of ANC related services was directly observed at five health posts followed by a recall interview at 6 months postpartum. A week later, a survey module was re-administered to 30 women containing 15 questions about receipt of ANC care and specifically nutrition-related services. Detailed probing was used to identify cognitive challenges related to comprehension, retrieval, judgement, and response. Respondents accurately recalled the four specific ANC visits recommended by the government of Nepal but those with more visits struggled to estimate the total number of ANC visits they had made. A number of terms including "antenatal care, "nutrition" and "breastfeeding" were challenging for many respondents to understand. Visits to private providers including for ultrasounds were inconsistently included in ANC visit counts suggesting that question wording could better specify the type of care. Many respondents over-estimated the number of iron folic acid (IFA) supplements taken during pregnancy, and recall was challenging. Calculations were based on estimating the number of months between first ANC visit to delivery, and only sometimes factored in missed tablets. Opportunities exist to improve questions to facilitate better comprehension by respondents through a combination of using local terms and explanations, reordering some questions, and adapting questions to better match respondents' approaches to estimating numeric responses.

Validation of Maternal Report of Receipt of Iron-Folic Acid Supplementation during Antenatal Care in Rural Southern Nepal.

BACKGROUND: Coverage of iron-folic acid (IFA) supplementation is a key indicator for tracking programmatic progress within and across countries. However, the validity of maternal report of this information during household surveys has yet to be determined. OBJECTIVES: This study aimed to examine the validity of maternal recall of receipt of IFA supplementation during antenatal care (ANC) and factors associated with accuracy of maternal recall. METHODS: A longitudinal cohort design was employed. The direct observation of the IFA received during all ANC visits at the 5 study health posts served as the "gold standard" to the maternal report of IFA received during the postpartum interview. Individual-level validity was assessed by calculating indicator sensitivity, specificity, and AUC. The inflation factor (IF) measured population-level bias. A multivariable log-binomial model was used to assess factors associated with accurate recall. RESULTS: The majority (95.8%) of women were observed receiving IFA during pregnancy. Women overreported the number of IFA tablets received compared with what was observed during ANC visits (mean difference: 45 tablets). Maternal report of any IFA receipt was moderate (AUC = 0.60; 95% CI: 0.50, 0.71), and population bias was low (IF = 1.01). However, the individual-level validity was poor across the 7 IFA tablet count categories; the AUC for categories ranged from misleading to moderate. Driven by the trend of maternal overreport, the IF indicated that maternal report drastically underestimated the coverage of lower tablet categories and overestimated the coverage of higher tablet counts. Accuracy of maternal report was not associated with months since last ANC observation nor any maternal characteristics. CONCLUSIONS: Maternal report of the amount of IFA supplementation received during pregnancy produced extremely biased population coverage and performed poorly to moderately for individual-level validity. It is imperative to improve this indicator because it is used in global frameworks and national program planning.

Validation of maternal report of nutrition-related interventions and counselling during antenatal care in southern Nepal.

The delivery of nutrition-related interventions and counselling during antenatal care is critical for a healthy pregnancy for both mother and child. However, the accuracy of maternal reports of many of these services during household surveys has not yet been examined. Our objectives were to assess the validity of the maternal reports of 10 antenatal nutrition interventions, including counselling, and examine associates between maternal characteristics and accuracy. Maternal report of services received collected during a post-partum survey was compared to the gold standard, the direct observation of all women's antenatal care visits. Individual-level validity was assessed by calculating indicator sensitivity, specificity and area under the operating curve (AUC). The inflation factor (IF) measured population-level bias. For five indicators, the high true coverage limited our ability to assess the validity of the maternal reports. There were no indicators that had both high individual-level validity (AUC > 0.70) and low population bias (0.75 < IF < 1.25). Indicators with greater true coverage estimates had higher sensitivity and lower specificity estimates compared to those indicators with lower true coverage. There were no maternal characteristics associated with the accuracy of the report. Maternal report of antenatal nutrition-related interventions and counselling during household surveys was found to have variable validity across indicators. Additional research in settings with varying coverage levels should be considered to best inform antenatal care coverage measurement in household surveys.

Alcohol Consumption and Risky Sexual Behavior Among Persons Attending Alcohol Consumption Venues in Gaborone, Botswana.

Alcohol use is a known key risk factor associated with risky sexual behavior that contributes to HIV transmission. This cross-sectional study used time location sampling to investigate alcohol use and risky sexual behaviors that occurred after ingesting alcohol among 609 patrons of alcohol venues in Gaborone, Botswana. Alcohol Use Disorders Identification Test (AUDIT) scores were categorized as low (1-7), medium (8-15), and high (16+) for analysis. Logistic regression models stratified by gender assessed the association between alcohol use and condom use at last sex after drinking alcohol. Among females, the odds of condom use during last sex after drinking alcohol were significantly lower for high compared to low AUDIT scores (AOR = 0.17, 95% CI 0.06-0.54). Among males, factors significantly associated with condom use at last sex after alcohol use were low levels of education (primary level compared to university and above AOR = 0.13; 95% CI 0.03-0.55) and beliefs that alcohol use did not increase risky sexual behaviors (AOR = 0.26; 95% CI 0.11-0.62). HIV prevention interventions should target females and emphasize sexual risks associated with alcohol use.
