ABSTRACT

BACKGROUND: Increased mobile phone penetration allows the interviewing of respondents using interactive voice response surveys in low- and middle-income countries. However, there has been little investigation of the best type of incentive to obtain data from a representative sample in these countries. OBJECTIVE: We assessed the effect of different airtime incentives options on cooperation and response rates of an interactive voice response survey in Bangladesh and Uganda. METHODS: The open-label randomized controlled trial had three arms: (1) no incentive (control), (2) promised airtime incentive of 50 Bangladeshi Taka (US $0.60; 1 BDT is approximately equivalent to US $0.012) or 5000 Ugandan Shilling (US $1.35; 1 UGX is approximately equivalent to US $0.00028), and (3) lottery incentive (500 BDT and 100,000 UGX), in which the odds of winning were 1:20. Fully automated random-digit dialing was used to sample eligible participants aged ≥18 years. The risk ratios (RRs) with 95% confidence intervals for primary outcomes of response and cooperation rates were obtained using log-binomial regression. RESULTS: Between June 14 and July 14, 2017, a total of 546,746 phone calls were made in Bangladesh, with 1165 complete interviews being conducted. Between March 26 and April 22, 2017, a total of 178,572 phone calls were made in Uganda, with 1248 complete interviews being conducted. Cooperation rates were significantly higher for the promised incentive (Bangladesh: 39.3%; RR 1.38, 95% CI 1.24-1.55, P<.001; Uganda: 59.9%; RR 1.47, 95% CI 1.33-1.62, P<.001) and the lottery incentive arms (Bangladesh: 36.6%; RR 1.28, 95% CI 1.15-1.45, P<.001; Uganda: 54.6%; RR 1.34, 95% CI 1.21-1.48, P<.001) than those for the control arm (Bangladesh: 28.4%; Uganda: 40.9%). Similarly, response rates were significantly higher for the promised incentive (Bangladesh: 26.5%%; RR 1.26, 95% CI 1.14-1.39, P<.001; Uganda: 41.2%; RR 1.27, 95% CI 1.16-1.39, P<.001) and lottery incentive arms (Bangladesh: 24.5%%; RR 1.17, 95% CI 1.06-1.29, P=.002; Uganda: 37.9%%; RR 1.17, 95% CI 1.06-1.29, P=.001) than those for the control arm (Bangladesh: 21.0%; Uganda: 32.4%). CONCLUSIONS: Promised or lottery airtime incentives improved survey participation and facilitated a large sample within a short period in 2 countries.

ABSTRACT

In light of the suboptimal noncommunicable disease (NCD) risk factor surveillance efforts, the study's main objectives were to: (i) characterize the epidemiological profile of NCD risk factors; (ii) estimate the prevalence of hypertension; and (iii) identify factors associated with hypertension in a peri-urban and rural Ugandan population. A population-based cross-sectional survey of adults was conducted at the Iganga-Mayuge Health and Demographic Surveillance System site in eastern Uganda. After describing sociodemographic characteristics, the prevalence of NCD risk factors and hypertension was reported. Prevalence ratios for NCD risk factors were calculated using weighted Poisson regression to identify factors associated with hypertension. Among 3220 surveyed respondents (mean age: 35.3 years (standard error: 0.1), 49.4% males), 4.4% were current tobacco users, 7.7% were current drinkers, 98.5% had low fruit and vegetable consumption, 26.9% were overweight, and 9.3% were obese. There was a high prevalence of hypertension and prehypertension, at 17.1% and 48.8%, respectively. Among hypertensive people, most had uncontrolled hypertension, at 97.4%. When we examined associated factors, older age (adjusted prevalence ratio (APR): 3.1, 95% CI: 2.2-4.4, APR: 5.2, 95% CI: 3.7-7.3, APR: 8.9, 95% CI: 6.4-12.5 among 30-44, 45-59, and 60+-year-old people than 18-29-year-olds), alcohol drinking (APR: 1.6, 95% CI: 1.3-2.0, ref: no), always adding salt during eating (APR: 1.6, 95% CI: 1.1-2.2, ref: no), poor physical activity (APR: 1.3, 95% CI: 1.1-1.6, ref: no), overweight (APR: 1.3, 95% CI: 1.1-1.5, ref: normal weight), and obesity (APR: 2.0, 95% CI: 1.6-2.4, ref: normal weight) had higher prevalence of hypertension than their counterparts. The high prevalence of NCD risk factors highlights the immediate need to implement and scale-up population-level strategies to increase awareness about leading NCD risk factors in Uganda. These strategies should be accompanied by concomitant investment in building health systems capacity to manage and control NCDs.

ABSTRACT

BACKGROUND: Unintentional childhood injuries are a growing public health concern, and the home is the most common location for non-fatal injuries in children less than 5 years of age. This study describes the long-term effects of two injury prevention educational interventions for caregivers-an educational pamphlet and an in-home tutorial guide-by comparing the change in the prevalence of home injury hazards before and after the interventions. METHODS: This was a pre- (June and July 2010) and post-study with short-term follow-up (November-December 2010) and long-term follow-up (November 2012- January 2013). Neighborhood one included households that received only educational pamphlets after completing a baseline assessment; neighborhood two included households that received an in-home tutorial guide after completing the baseline assessment and receiving the educational pamphlet. The main outcome of this study was the reduction in home injury hazards for children under 5 years of age. RESULTS: A total of 312 households participated in the long-term phase to compare the effect of the interventions. Between the short-term to long-term follow-up, injury hazards significantly reduced in neighborhood two compared to neighborhood one. These included fall hazards (walker use) (IRR 0.24 [95% CI 0.08-0.71]), drowning hazards (open bucket of water in the courtyard and uncovered water pool) (IRR 0.45 [95% CI 0.85-0.98] and IRR 0.46 [95% CI 0.76-0.94]), burn hazards (iron, water heater within reach of child) (IRR 0.56 [95% CI 0.33-0.78] and IRR 0.58 [95% CI 0.32-0.91]), poisoning hazards (shampoo/soap and medicine within reach of child) (IRR 0.53 [95% CI 0.44-0.77] and IRR 0.7 [95% CI 0.44-0.98]) and breakable objects within reach of child (IRR 0.62 [95% CI: 0.39-0.99]). CONCLUSION: An injury prevention tutorial to caretakers of children supplemented with pamphlets could significantly decrease the incidence of falls, drowning, burns, poisoning, and cut injury hazards for children under 5 years of age in their homes in a low-resource setting. This intervention has the potential to be integrated in existing public health programs, such as Lady Health Visitors (LHVs), to disseminate injury prevention information in routine home health visits.

ABSTRACT

BACKGROUND: Mobile phone surveys provide a novel opportunity to collect population-based estimates of public health risk factors; however, nonresponse and low participation challenge the goal of collecting unbiased survey estimates. OBJECTIVE: This study compares the performance of computer-assisted telephone interview (CATI) and interactive voice response (IVR) survey modalities for noncommunicable disease risk factors in Bangladesh and Tanzania. METHODS: This study used secondary data from a randomized crossover trial. Between June 2017 and August 2017, study participants were identified using the random digit dialing method. Mobile phone numbers were randomly allocated to either a CATI or IVR survey. The analysis examined survey completion, contact, response, refusal, and cooperation rates of those who received the CATI and IVR surveys. Differences in survey outcomes between modes were assessed using multilevel, multivariable logistic regression models to adjust for confounding covariates. These analyses were adjusted for clustering effects by mobile network providers. RESULTS: For the CATI surveys, 7044 and 4399 phone numbers were contacted in Bangladesh and Tanzania, respectively, and 60,863 and 51,685 phone numbers, respectively, were contacted for the IVR survey. The total numbers of completed interviews in Bangladesh were 949 for CATI and 1026 for IVR and in Tanzania were 447 for CATI and 801 for IVR. Response rates for CATI were 5.4% (377/7044) in Bangladesh and 8.6% (376/4391) in Tanzania; response rates for IVR were 0.8% (498/60,377) in Bangladesh and 1.1% (586/51,483) in Tanzania. The distribution of the survey population was significantly different from the census distribution. In both countries, IVR respondents were younger, were predominantly male, and had higher education levels than CATI respondents. IVR respondents had a lower response rate than CATI respondents in Bangladesh (adjusted odds ratio [AOR]=0.73, 95% CI 0.54-0.99) and Tanzania (AOR=0.32, 95% CI 0.16-0.60). The cooperation rate was also lower with IVR than with CATI in Bangladesh (AOR=0.12, 95% CI 0.07-0.20) and Tanzania (AOR=0.28, 95% CI 0.14-0.56). Both in Bangladesh (AOR=0.33, 95% CI 0.25-0.43) and Tanzania (AOR=0.09, 95% CI 0.06-0.14), there were fewer completed interviews with IVR than with CATI; however, there were more partial interviews with IVR than with CATI in both countries. CONCLUSIONS: There were lower completion, response, and cooperation rates with IVR than with CATI in both countries. This finding suggests that, to increase representativeness in certain settings, a selective approach may be needed to design and deploy mobile phone surveys to increase population representativeness. Overall, CATI surveys may offer a promising approach for surveying potentially under-represented groups like women, rural residents, and participants with lower levels of education in some countries.

ABSTRACT

OBJECTIVES: Injuries are among the top causes of hospital-based mortality for adults in Oman. However, little is known about the distribution and risk of injuries among children. This paper describes the epidemiology and risk factors for childhood injuries (0-15 years of age), in two hospitals of Oman. METHODS: Data were collected between November 2014 and April 2015 at Khoula and Nizwa Hospitals. All patients between 0 and 15 years with a diagnosis of injury/trauma admitted to the hospital, and those who had trauma team activation in the emergency department were included in the analysis. Descriptive and multivariable Poisson regression analyses were conducted to generate sociodemographic risk factor profiles associated with the need for surgical management of injuries. RESULTS: Out of 795 cases, 59% were under 5 years of age; 67% were males. Around 50% injuries were fall related, followed by exposure to inanimate mechanical forces and transport injuries. Burn injuries were more prevalent in females than males. Three-fourths of all injuries occurred in private residences. Almost 92% injuries were minor (Injury Severity Score <9). Of children with all types of injuries, 303 (40.9%) received surgical treatment. Patients suffering from head injuries (RR 8.8: 95% CI 4.9 to 15.3) or being involved in a burn injury (RR 1.5: 95% CI 0.3 to 7.5) were at increased risk of undergoing surgical treatment. CONCLUSION: In this study, >30% of injury admissions were children 0-15 years of age. The high incidence of falls, home injuries and burns highlight the need for age-targeted interventions and injury control programmes. Although infrequent, transport injuries and head injuries put children in need of surgical management and prolonged hospital care.

ABSTRACT

World Health Organization has identified violence against children as a growing public-health issue with a global magnitude. This paper explored violence against children as a challenge in the developing world using Pakistan as a case study. A systematic review of existing research and literature on violence against children was followed by assessing the magnitude of this challenge and its impact on policy. Most research done in Pakistan is observational, descriptive, and anecdotal with data collected through survey methods and interviews with small sample sizes. The findings suggest that the confluence of macro risk factors, such as poverty, poor legal protections, illiteracy, large family size, and unemployment, create an enabling environment for violence against children. Lack of empirical data makes it difficult to assess the magnitude of this issue. The health problems reported and the extent of human potential destroyed are unknown. Conclusion calls for focused research to examine the prevalence, potential interventions, and policies in Pakistan.

ABSTRACT

Over a million people died from road traffic injuries (RTI) globally in the year 2000 and as many as 50 million were injured. Yet there has been little work focused on the South Asia region, let alone the vulnerable segments of population such as children and adolescents. This study aims at measuring the burden of disease caused by urban road traffic injuries among children and adolescents in South Asia. This study selected 26 studies for review and data extraction out of 1505 published articles. Data from the studies were pooled to calculate the proportion and characteristics of child and adolescent RTI, regional RTI incidence and mortality rates, and an estimate of the burden of disease caused by these injuries through the use of the healthy life years lost (HeaLY) composite measure. Our findings showed that the majority of injuries occurred in males (67-80%) and the most frequent age group injured was between ages 0 and 9 representing 40% of cases. Children and adolescents represent an average of 22% of all those with RTI whom seek care. Children and adolescents represented an average of 13% of all RTI deaths. Regional RTI incidence rate was calculated at 880 per 100,000 urban persons aged 0-19. Mortality due to RTI was at 17 deaths per 100,000 urban persons aged 0-19 in South Asia. Burden of disease was calculated 16 HeaLYs per 1000 general population from road traffic mortality alone. With disability data added, then 27.7 HeaLYs per 1000 general population are lost from road traffic injuries in South Asia. The increasing burden of RTI in young persons in South Asia is a call for considering appropriate research and effective interventions. This relatively high loss of healthy life from RTI needs to be addressed by public health systems in South Asia.

ABSTRACT

There are no official data on suicide from Pakistan, a conservative South Asian Islamic country with traditionally low suicide rates. Both suicide and attempted suicide are illegal acts, as well as socially and religiously condemned, making research in this area difficult. Recent reports suggest an increase in suicide rates. In this study, police data from the Sindh province were examined to provide a unique picture of trends of suicide over 15 years (1985-1999). During this period there were 2,568 reported suicides (71% men, 39% women; ratio 1.8). The lowest number was 90 in 1987 and maximum was 360 in 1999. Poisoning by organophosphates was the most common method followed by hanging. This study, although limited in scope, provides evidence of an increase in suicide rates in Pakistan, from one data source. There is urgent need for further research on suicide in Pakistan; interventions for suicide prevention in the country can then be planned.

ABSTRACT

This article reviews evidence of the economic impact of interpersonal violence internationally. In the United States, estimates of the costs of interpersonal violence reach 3.3% of GDP. The public sector-and thus society in general-bears the majority of these costs. Interpersonal violence is defined to include violence between family members and intimate partners, and violence between acquaintances and strangers that is not intended to further the aims of any formally defined group or cause. Although these types of violence disproportionately affect poorer countries, there is a scarcity of studies of their economic impact in these countries. International comparisons are complicated by the calculation of economic losses based on foregone wages and income, thus undervaluing economic losses in poorer countries.

ABSTRACT

OBJECTIVE: To pilot an in-home unintentional injury hazard assessment tool and to quantify potential injury risks for young children in a low-income urban setting. METHODS: Two low-income neighbourhoods in Karachi, Pakistan, were mapped, and families with at least one child between the ages of 12 and 59 months were identified. Using existing available home injury risk information, an in-home injury risk assessment tool was drafted and tailored to the local setting. Home injury assessments were done in June-July 2010 after obtaining informed consent. RESULTS: Approximately 75.4% of mothers were educated through at least grade 12. The main risks identified were stoves within the reach of the child (n=279, 55.5%), presence of open buckets in the bathroom (n=240, 47.7%) within the reach of the child, and pedestal fans accessible to the child (n=242, 48.1%). In terms of safety equipment, a first-aid box with any basic item was present in 70% of households, but only 4.8% of households had a fire extinguisher in the kitchen. CONCLUSIONS: This was the first time that an in-home, all-unintentional injury risk assessment tool was tailored and applied in the context of a low-income community in Pakistan. There was a significant burden of hazards present in the homes in these communities, representing an important opportunity for injury prevention. This pilot may have future relevance to other LMICs where child injury prevention is a critical need.

ABSTRACT

OBJECTIVE: To identify and estimate the population costs and effects of a selected set of enforcement strategies for reducing the burden of road traffic injuries in developing countries. DESIGN: Cost effectiveness analysis based on an epidemiological model. SETTING: Two epidemiologically defined World Health Organization sub-regions of the world: countries in sub-Saharan Africa with very high adult and high child mortality (AfrE); and countries in South East Asia with high adult and high child mortality (SearD). INTERVENTIONS: Enforcement of speed limits via mobile speed cameras; drink-drive legislation and enforcement via breath testing campaigns; legislation and primary enforcement of seatbelt use in cars; legislation and enforcement of helmet use by motorcyclists; legislation and enforcement of helmet use by bicyclists. MAIN OUTCOME MEASURES: Patterns of injury were fitted to a state transition model to determine the expected population level effects of intervention over a 10 year period, which were expressed in disability adjusted life years (DALYs) averted. Costs were expressed in international dollars ($Int) for the year 2005. RESULTS: The single most cost effective strategy varies by sub-region, but a combined intervention strategy that simultaneously enforces multiple road safety laws produces the most health gain for a given amount of investment. For example, the combined enforcement of speed limits, drink-driving laws, and motorcycle helmet use saves one DALY for a cost of $Int1000-3000 in the two sub-regions considered. CONCLUSIONS: The potential impact of available road safety measures is inextricably bound by the underlying distribution of road traffic injuries across different road user groups and risk factors. Combined enforcement strategies are expected to represent the most efficient way to reduce the burden of road traffic injuries, because they benefit from considerable synergies on the cost side while generating greater overall health gains.
