PublicationStagnant Stunting Rate Despite Rapid Economic Growth in Papua New Guinea: Factors Correlated with Malnutrition among Children under Five(World Bank, Washington, DC, 2015-06) Hou, XiaohuiMaternal and child undernutrition is a pervasive and detrimental condition in Papua New Guinea. Despite rapid economic growth during the past decade, the stunting rate for children under 5, one of the primary indicators for child undernutrition, was estimated at 46 percent in Papua New Guinea in 2010, stagnant from 44 percent in 2005. This paper analyzes the association between the demographic, socioeconomic, environmental, and health-related factors on nutritional status for children under age 5 years, using the 2009–10 Papua New Guinea Household Income and Expenditure Survey. Stunting and underweight rates sharply rise in the first 24 months. Even in the better-off quintiles, children suffer from suboptimal breastfeeding and complementary food in the first 24 months. In general, the regression results showed that household wealth and geographic location are crucial factors that contribute to children’s malnutrition. More importantly, food quality, measured by protein intake, has significant predicting power on child malnutrition. Broadly increasing socioeconomic status and improving the quantity and quality of caloric intake are general steps to improving health outcomes in Papua New Guinea. In addition, three key areas were identified as critical to alleviating the persistent and detrimental stunting rate in the country: (1) exclusive breastfeeding and complementary food; (2) interventions by health workers; and (3) nutrition education. PublicationA Snapshot of Health Equity in Papua New Guinea: An Analysis of the 2010 Household Income and Expenditure Survey(World Bank, Washington, DC, 2015-06) Irava, Wayne; Barker, Katie; Somanathan, Aparnaa; Hou, XiaohuiThis paper highlights challenges that the government of Papua New Guinea faces in delivering equitable health care. It analyses findings from the 2010 household survey, including sickness reporting, health service utilization and out of pocket expenditure, concluding that the poorest quintile is most vulnerable to illness, yet has the lowest utilization rates of healthcare facilities. The lack of healthcare workers and the distance to facilities are among the most dominant reasons cited for not utilizing healthcare facilities in the poorest quintile while out-of-pocket payments have minimal catastrophic impact, yet have still been found to be a barrier to utilization. The paper also sets out policy implications of these findings, including the need for the government to focus on, and prioritize, strengthening the health services delivery to achieve universal health coverage. PublicationDeterminants of Tobacco Consumption in Papua New Guinea: Challenges in Changing Behaviors(World Bank, Washington, DC, 2015-06) Hou, Xiaohui; Anderson, IanThis paper analyzes smoking prevalence and smoking behaviors in Papua New Guinea. Using the 2009–10 Papua New Guinea Household Income and Expenditure Survey, the paper analyzes the determinants of tobacco use and tobacco choices in Papua New Guinea. The results show that adults (18 years and above) in the poorest quartile are more likely to smoke. Tobacco consumption imposes a large financial burden to poor households. Tobacco consumption accounts for about 23 percent of total household food expenditure for households in the poorest quartile, compared with 15 percent for the entire sample. However, most of these households consume non-processed tobacco. The study reveals the urgency to control tobacco consumption in Papua New Guinea and considers some practical challenges that the country may face. PublicationFinancing the Frontline in Papua New Guinea: An Analytical Review of Provincial Administrations' Rural Health Expenditure 2006-2012(World Bank, Washington, DC, 2015-09) Cairns, Alan; Hou, XiaohuiFinancing the Frontline updates the expenditure analysis carried out in Below the Glass Floor (2013) and tests whether the spending patterns emerging in 2009 and 2010 in Papua New Guinea have been sustained or improved in 2011 and 2012. The review also supports a better understanding of the issues that confront frontline service delivery — such as the ambiguity of roles and responsibilities in some rural health functions — and proposes next steps. Concurrently, the National Department of Health performance information on facilities (from the National Health Information System) has been reviewed. The integration of the expenditure analysis, the NHIS performance information and the findings from the Promoting Effective Public Expenditure facility surveys will provide a rich source of information to help sharpen understanding and shape solutions. PublicationA Snapshot of Health Equity in Papua New Guinea: An Analysis of the 2010 Household Income and Expenditure Survey(World Bank, Washington, DC, 2015-05) Irava, Wayne; Barker, Katie; Somanathan, Aparnaa; Hou, XiaohuiIn Papua New Guinea the poorest quintile is most vulnerable to illness, yet has the lowest utilization rates of healthcare facilities. When looking at age groups the elderly ( 55) are the most vulnerable to illness and the least likely to seek treatment. The lack of healthcare workers and the distance to facilities are among the most dominant reasons cited for not utilizing heath care in the poorest quintile. The perceived quality of services is a barrier to health care utilization across all quintiles. Out-of-pocket (OOP) payments have minimal catastrophic impact, yet have been found to still be a barrier to utilization - especially amongst the poorest quintile. The government should focus on and prioritize strengthening the health services delivery to achieve universal health coverage. PublicationExploring Factors Driving the Performance of Rural Health Care in Papua New Guinea(World Bank, Washington, DC, 2018-06-06) Cairns, Alan; Witter, Sophie; Hou, XiaohuiExamining performance patterns of sub-national units, such as provinces and districts, within a health system is important to understand their drivers and what might be needed to improve outputs. Such literature is relatively rare in low and middle-income countries. It is particularly relevant for Papua New Guinea, which is underperforming in relation to its neighbours and targets for core health indicators and faces particular geographical challenges, with a dispersed and diverse population. In this analysis, we undertake simple correlation analysis between remoteness of populations, expenditure on frontline services and core outputs by provinces and regions, such as antenatal care, outpatient visits, outreach clinics, referrals of patients and facility supervision in 2012. In the context of the challenging geography of Papua New Guinea, these are expected to be important factors. Some expected patterns were found – for example, between remoteness and higher service costs, as well as between remoteness and higher outreach services. Outpatient visits, however, increased with remoteness, which was surprising. Our correlation analyses suggest a virtuous circle operating in some areas (even in the most geographically challenged) between outreach clinics, immunisation coverage, supervision, frontline spending and overall health system performance, which merits further investigation into the factors supporting these and how they can be reinforced elsewhere. Whilst expenditure did not correlate closely with provincial performance, it was evident that the provinces with higher performance across the selection of metrics typically were also the higher spenders on frontline services. There was some correlation of higher performance with density of public provision. More fine-grained assessment, including at the district level, will be needed to understand the low levels of outreach clinics, transfers and supervision, all of which are critical for quality health care in these kinds of contexts. The analysis illustrates what can be learned from combining routine data sources, as well as the limits and the need to complement such analysis with more detailed local qualitative investigations. It also reinforces the message that local leadership, supportive supervision and resources directed to frontline services can be effective in raising health system performance, even in challenging settings.
