BackgroundNeonatal mortality is declining slowly compared to under-five mortality in many developing countries including Afghanistan. About three-fourths of these deaths occur in the early neonatal period (i.e., the first week of life). Although a number of studies investigated determinants of early neonatal mortality in other countries, there is a lack of evidence regarding this in Afghanistan. This study investigated determinants of early neonatal mortality in Afghanistan.MethodsData from the Afghanistan Demographic and Health Survey 2015 (AfDHS 2015) were analyzed. After reporting the weighted frequency distributions of selected factors, a multilevel logistic regression model revealed adjusted associations of factors with early neonatal mortality.ResultsA total of 19,801 weighted live-births were included in our analysis; 266 (1.4%) of the newborns died in this period. Multivariable analysis found that multiple gestations (adjusted odds ratio (AOR): 9.3; 95% confidence interval (CI): 5.7–15.0), larger (AOR: 2.9; 95% CI: 2.2–3.8) and smaller (AOR: 1.8; 95% CI: 1.2–2.6) than average birth size, maternal age ≤ 18 years (AOR: 1.8; 95% CI: 1.1–3.2) and ≥ 35 years (AOR: 1.7; 95% CI: 1.3–2.3), and birth interval of < 2 years (AOR: 2.6; 95% CI: 1.4–4.9) had higher odds of early neonatal mortality. On the other hand, antenatal care by a skilled provider (AOR: 0.7; 95% CI: 0.5–0.9), facility delivery (AOR: 0.7; 955 CI: 0.5–0.9), paternal higher education level (AOR: 0.7; 95% CI: 0.5–1.0), living in north-western (AOR: 0.3; 95% CI: 0.1–0.6), central-western regions (AOR: 0.5; 95% CI: 0.3–0.9) and in a community with higher maternal education level (AOR: 0.4; 95% CI: 0.2–0.9) had negative association.ConclusionsSeveral individual, maternal and community level factors influence early neonatal deaths in Afghanistan; significance of the elements of multiple levels indicates that neonatal survival programs should follow a multifaceted approach to incorporate these associated factors. Programs should focus on birth interval prolongation with the promotion of family planning services, utilization of antenatal care and institutional delivery services along with management of preterm and sick infants to prevent this large number of deaths in this period.

Key Points Question What is the change in prevalence of hypertension among adults in Nepal due to lowering the blood pressure threshold in the 2017 American College of Cardiology/American Heart Association (ACC/AHA) hypertension guideline? Findings Using data from the nationally representative 2016 Nepal Demographic and Health Survey, the estimated prevalence of hypertension was 44.2% according to the 2017 ACC/AHA guideline, 23% higher than the estimate under previous guidelines (21.2%). Meaning The new estimates suggest that nearly half of adults in Nepal may have hypertension; these results support the need for public health programs to increase awareness and minimize complications of hypertension.

We analyzed the Bangladesh Demographic and Health Survey 2011 data to examine absolute differences in hypertension prevalence according to the hypertension definition of the "2017 American College of Cardiology/American Heart Association (2017 ACC/AHA) Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults" and "Seventh Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC7)" 2003 guidelines. Among 7839 participants ≥35 years, the JNC7 and 2017 ACC/AHA classified 25.7% (95% confidence interval (CI): 24.5-27.0%) and 48.0% (95% CI: 46.4-49.7%) people hypertensive, respectively. The JNC7 prevalence was 19.4% (95% CI: 18.0-21.0%) among males and 31.9% (95% CI: 30.1-33.6%) among females. The prevalence was 41.4% (95% CI: 39.4-43.5%) among males and 54.5% (95% CI: 52.4-56.4%) among females as per the 2017 ACC/AHA guideline. From JNC7 to 2017 ACC/AHA, the overall difference in prevalence was 22.3% (95% CI: 19.8-24.8%). Males and females had similar differences, 22.0% (95% CI: 18.3-25.7%) and 22.6% (95% CI: 19.4-26.0%), respectively. As per the 2017 ACC/AHA guideline, >50% prevalence was observed among people with body mass index ≥25 kg/m, college-level education, co-morbid diabetes, richest wealth quintile, females, age ≥55 years, urban residence, or living in Khulna, Rangpur or Dhaka divisions; the absolute difference was >20% in most categories. We found a substantial increase in the prevalence of hypertension due to change in blood pressure thresholds as per the 2017 ACC/AHA guideline. We recommend conducting more comprehensive population-based studies to estimate the recent burden of hypertension in Bangladesh. Future studies should estimate similar prevalence in other countries.
