Publication Estimation of Causes of Death in Suburban Nepal Using Verbal Autopsy(Kathmandu University, 2016) Ide, N; Fitzpatrick, AL; Flaxman, AD; Koju, R; Tamrakar, D; Hernandez, BABSTRACT Background Nepal is in the midst of a disease transition, including a rapid increase of non- communicable diseases. In order for health policy makers and planners to make informed programmatic and funding decisions, they need up to date and accurate data regarding cause of death throughout the country. Methods of improving cause of death reporting in Nepal are urgently required. Objective We sought to validate SmartVA-Analyze, an application which computer certifies verbal autopsies, to evaluate it as a method for collecting mortality data in Nepal. Method We conducted a medical record review of mortality cases at Dhulikhel Hospital, Kathmandu University Hospital. Cases with a verifiable underlying cause of death were used as gold standard reference cases. Verbal autopsies were conducted with caregivers of 48 gold standard cases. Result Of the 66 adult gold standard mortality cases reviewed, 76% were caused by cancer, cirrhosis, cardiovascular disease, COPD or injury. When assessing concordance between cause of death from verbal autopsy vs. gold standards, we found an overall agreement (Kappa) of 0.50. Kappa based on broader ICD-10 categories was 0.69. Cause-Specific Mortality Fraction Accuracy was 0.625, and disease specific measures of concordance varied widely, with sensitivities ranging from 0-100%. Conclusion Ongoing, countrywide mortality data collection is crucial for evidence-based priority setting in Nepal. Though not valid for all causes, we found SmartVA-Analyze to provide useful general cause of death data, particularly in settings where death certification is unavailable.

The distribution of tobacco consumption in Nepal varies across the population subgroups. There is little information on the correlates of tobacco use among suburban population in Nepal. Objective To estimate the prevalence of smoking and oral tobacco use; and determine the socio-demographic and other CVD risk factors associated with them in a suburban population of Dhulikhel, Nepal. Method This cross sectional study utilized data from the first wave of the baseline survey of the Dhulikhel Heart Study (DHS). A total of 2225 households of Dhulikhel city were enumerated and a third of the households (n=735) were randomly selected. Questions on tobacco use were ascertained from 1073 adults age 18 years and older using the questions based on the WHO STEPS survey questionnaire. Result More than a third (36%) of the men were current smokers and 12% reported regular use of oral tobacco. About 14% of the women were current smokers and only 0.5% reported to use oral tobacco regularly.In the multivariate analysis, sex, ethnicity, education, alcohol consumption and body mass index were significantly associated with tobacco use. Males were 2.6 times as likely as females to smoke (95%: 1.53-4.59; p<0.001). Brahmin/Chhetri were 2.8 times more likely to smoke compared to Newars (95% Ci: 1.53-5.18; p=0.001). Education reduced the odds of smoking; compared to those with no formal education, those with up to high school and those with a high school degree or higher were 0.50 (95% CI: 0.27-0.92; p=0.02 ) and 0.38 (95% CI: 0.16-0.91; p=0.03) percent less likely to smoke, respectively. Moderate drinkers were 8 times more likely (95% CI: .54 – 18.40; p<0.001) and high drinkers were 13 times (95% CI: 6.63 – 24.26; p<0.001) compared to non-drinkers. Regarding oral tobacco use males were 15 times as likely as females to use oral tobacco (95% CI: 4.1-58.8; p<0.001). Compared to Newars, Brahmin/Chhetri were 2.7 times as likely to use oral tobacco (95% CI: 1.08 – 6.66; p=0.03). Conclusion Although Nepal has made some progress in passing progressive laws for tobacco control, and national surveys have shown slight reduction on tobacco use, this is far from satisfactory to meet the global target of bringing tobacco consumption to less than 5% by 2040. We recommend future studies to focus on socio-cultural, gender and behavioral aspects of tobacco use in addition to the epidemiological aspects. KEY WORDS Dhulikhel, Heart study, Sub-urban, TobaccoPublication Quit Intentions and Attempts among Smokers in Sub-urban Nepal: Findings from the Dhulikhel Heart Study(Kathmandu University, 2018) Karmacharya, BM; Fitzpatrick, AL; Koju, R; Sotodehnia, N; Xu, DR; Pradhan, PMS; Shrestha, AABSTRACT Background The most effective way for smokers to avoid or minimize the harmful effects is to quit smoking. Smoking cessation has been attributed to multiple factors operating at physiological, psychological, environmental and social level. There is common consensus that smoking cessation programs should be tailored for specific populations. However, there has been lack of data regarding factors that influence smoking cessation in Nepal, which has hindered the development of effective smoking-cessation interventions. Objective To assess the prevalence of quit attempts, successful quitting and the factors associated with them in a randomly selected, population-based adult participants in sub-urban Nepal. Method This cross-sectional study utilized data from the first wave of the baseline survey of the Dhulikhel Heart Study (DHS). A total of 2225 households of Dhulikhel city were enumerated and a third of the households (n=735) were randomly selected. Questions on tobacco use were ascertained using the questions based on the WHO STEPS survey questionnaire and questions on past quit attempts. Result Out of 1073 participants, 248 (23.1%) were current smokers and 99 (9.2%) were former smokers. Only 58% of the current smokers mentioned that they had attempted to quit smoking. When asked if they were interested in quitting if helped, almost 90.5% mentioned they were willing. Brahmins were less likely to have quit smoking (former smoker) compared to Newars (OR: 0.41, 95% CI: 0.18-0.90). We also observed that those who had high alcohol consumption were less likely to have quit smoking (OR: 0.36, 95% CI: 0.17-0.76). We didn’t find any meaningful significant association between socio-demographic factors or other CVD risk factors and the quit attempts. Conclusion As the country braces to address the burden of non-communicable diseases in Nepal, it is crucial to incorporate tobacco cessation programs in the national health system to meet the global target of bringing tobacco consumption to less than 5% by 2040. We recommend future studies to get a broader understanding of quit effort and factors associated with thereby supporting the development of evidence-based strategies to address tobacco cessation.

The WHO (2014) has reported that indoor air pollution caused by cooking and heating with biomass fuel, living in crowed homes and parenting smoking are risk factors of pneumonia. Objectives The objective of the study was to identify the risk factors for pneumonia among children under-5 years of age. Methods A case control study was carried out among the mothers having under-5 years children who were admitted in the paediatric ward of Dhulikhel Hospital in 2012/13. A convenience sampling technique was used to select 50 children with pneumonia and 150 children with non-pneumonia diseases matched on age, sex and setting. A semi-structured interview consisting of questions related to risk factors for pneumonia was used to collect data from mothers of both cases and controls. Results Sex of the child did not differ by case/control group whereas the children with pneumonia were slightly older with 26% cases and 15% controls older than 3 years of age. Mother’s education was similar in both groups as was family income. Living in a household with a chulo with smoke increased the odds of having pneumonia significantly, with the risk almost 4 times greater if the chulo was located within the same building (OR: 3.76, 95% CI: 1.20-11.82, p=0.02). Children who had diarrhea in the past 3 months were protected from pneumonia (OR: 0.38, 95% CI: 0.18- 0.82, p=0.01). An increasing trend of pneumonia was observed among children of tobacco smoking parents with greater risk if both parents smoked; it was, however, not statically significant (OR: 2.21, 95% CI: 0.56-8.82, p=0.26). Conclusion The present study suggests that two factors related to smoke, presence of a smoky chulo in a household and both parents smoking, are modifiable risk factors related to pneumonia in young children. Reliable longitudinal studies, interventions, and programs to educate parents in prevention are important for reducing mortality and morbidities related to acute respiratory illnesses in Nepal.

Objective To identify factors that contributes to the high rate of infant mortality in the mountain zone in Nepal. Method Data were derived from the 2011 Nepal Demographic and Health Survey (NDHS). Infant mortality was analyzed across three ecological zones in a sample of 5,306 live births in the five years preceding the survey. The contribution of risk factors to the excess infant mortality was assessed using multiple logistic regression. Result Infant mortality rate (deaths per 1000 live births) in the ecological zones were 59 (95% CI: 36, 81), 44 (35, 53), and 40 (33, 47) for the mountain, hill and terai zones, respectively. Women living in the mountain zone were more likely to report that distance to care was a “big problem” and had a greater risk of infant mortality compared to the terai zone (OR=1.42, 95% CI: 1.01, 2.02, p=0.04). This increased risk was observed only among births to mothers who perceived distance to the nearest health facility as a “big problem” (aOR=1.57, 95% CI: 1.01, 2.40, p=0.04) controlling for other risk factors. Conclusion These findings suggest that the higher Infant mortality rate (IMR) in the mountain zone was among the women who perceived distance to health facilities as a big problem. Improved accessibility to health services, particularly in this zone, is an essential strategy for reducing infant mortality in Nepal.
