Status of birth and pregnancy outcome capture in Health Demographic Surveillance Sites in 13 countries.

OBJECTIVES: We compared pregnancy identification methods and outcome capture across 31 Health Demographic Surveillance System (HDSS) sites in 14 countries in sub-Saharan Africa and Asia. METHODS: From 2009 to 2014, details on the sites and surveillance systems including frequency of update rounds, characteristics of enumerators and interviewers, acceptable respondents were collected and compared across sites. RESULTS: The 31 HDSS had a combined population of over 2,905,602 with 165,820 births for the period. Stillbirth rate ranged from 1.9 to 42.6 deaths per 1000 total births and the neonatal mortality rate from 2.6 to 41.6 per 1000 live births. Three quarters (75.3%) of recorded neonatal deaths occurred in the first week of life. The proportion of infant deaths that occurred in the neonatal period ranged from 8 to 83%, with a median of 53%. Sites that registered pregnancies upon locating a live baby in the routine household surveillance round had lower recorded mortality rates. CONCLUSIONS: Increased attention and standardization of pregnancy surveillance and the time of birth will improve data collection and provide platforms for evaluations and availability of data for decision-making with implications for national planning.

The state of enrollment on the National Health Insurance Scheme in rural Ghana after eight years of implementation.

BACKGROUND: In 2004, Ghana implemented a national health insurance scheme (NHIS) as a step towards achieving universal health coverage. In this paper, we assessed the level of enrollment and factors associated with NHIS membership in two predominantly rural districts of northern Ghana after eight years of implementation, with focus on the poor and vulnerable populations. METHODS: A cross-sectional survey was conducted from July 2012 to December 2012 among 11,175 randomly sampled households with their heads as respondents. Information on NHIS status, category of membership and socio-demographic characteristics of household members was obtained using a structured questionnaire. Principal component analysis was used to compute wealth index from household assets as estimates of socio-economic status (SES). The factors associated with NHIS enrollment were assessed using logistic regression models. The reasons behind enrollment decisions of each household member were further investigated against their SES. RESULTS: Approximately half of the sampled population of 39,262 were registered with a valid NHIS card; 53.2% of these were through voluntary subscriptions by payment of premium whilst the remaining (46.8%) comprising of children below the ages of 18 years, elderly 70 years and above, pregnant women and formal sector workers were exempt from premium payment. Despite an exemption policy to ameliorate the poor and vulnerable households against catastrophic health care expenditures, only 0.5% of NHIS membership representing 1.2% of total exemptions granted on accounts of poverty and other social vulnerabilities was applied for the poor. Yet, cost of premium was the main barrier to NHIS registration (92.6%) and non-renewal (78.8%), with members of the lowest SES being worst affected. Children below the ages of 18 years, females, urban residents and those with higher education and SES were significantly more likely to be enrolled with the scheme. CONCLUSIONS: Despite the introduction of policy exemptions as an equity measure, the poorest of the poor were rarely identified for exemption. The government must urgently resource the Department of Social Welfare to identify the poor for NHIS enrollment.

Tackling malnutrition: a systematic review of 15-year research evidence from INDEPTH health and demographic surveillance systems.

BACKGROUND: Nutrition is the intake of food in relation to the body's dietary needs. Malnutrition results from the intake of inadequate or excess food. This can lead to reduced immunity, increased susceptibility to disease, impaired physical and mental development, and reduced productivity. OBJECTIVE: To perform a systematic review to assess research conducted by the International Network for the Demographic Evaluation of Populations and their Health (INDEPTH) of health and demographic surveillance systems (HDSSs) over a 15-year period on malnutrition, its determinants, the effects of under and over nutrition, and intervention research on malnutrition in low- and middle-income countries (LMICs). METHODS: Relevant publication titles were uploaded onto the Zotero research tool from different databases (60% from PubMed). Using the keywords 'nutrition', 'malnutrition', 'over and under nutrition', we selected publications that were based only on data generated through the longitudinal HDSS platform. All titles and abstracts were screened to determine inclusion eligibility and full articles were independently assessed according to inclusion/exclusion criteria. For inclusion in this study, papers had to cover research on at least one of the following topics: the problem of malnutrition, its determinants, its effects, and intervention research on malnutrition. One hundred and forty eight papers were identified and reviewed, and 67 were selected for this study. RESULTS: The INDEPTH research identified rising levels of overweight and obesity, sometimes in the same settings as under-nutrition. Urbanisation appears to be protective against under-nutrition, but it heightens the risk of obesity. Appropriately timed breastfeeding interventions were protective against malnutrition. CONCLUSIONS: Although INDEPTH has expanded the global knowledge base on nutrition, many questions remain unresolved. There is a need for more investment in nutrition research in LMICs in order to generate evidence to inform policies in these settings.

Review of contributions from HDSSs to research in sexual and reproductive health in low- and middle-income countries.

OBJECTIVE: To evaluate the contributions of the INDEPTH Network of health and demographic surveillance system (HDSS) members to research efforts and interventions on reproductive health in low- and middle-income countries (LMICs). METHODS: Review of peer-reviewed published papers on sexual and reproductive health (SRH) that use the HDSS framework through (i) an online search for publications using terminology related to HDSS, HIV, Maternal health, adolescent sexual and reproductive health, family planning/contraceptives and fertility, and (ii) asking INDEPTH member centres for information on their published papers on SRH publications that used the HDSS framework. A paper was included in the review only if it used HDSS data, dealt with SRH issues, and had been published in a peer-reviewed international journal. RESULTS: Most of the papers in the review focused on HIV, maternal health, family planning and adolescent sexual and reproductive health (ASRH). Generally, people are knowledgeable about HIV. School attendance considerably delays entry into motherhood and reduces the probability of entering into early marriage or sexual union. The general decline in maternal mortality over the last decade is partly due to better access to emergency obstetric services, improved education of women and reduction in fertility. CONCLUSION: Sexual and reproductive health is a significant public health need, yet little research has been published in this area to inform policy. The HDSS framework is ideal for SRH research, as it offers the advantage to track and monitor progress of relevant health and demographic indicators, especially in family planning, marriage and fertility studies.
